Abstract

The invention relates to a device for stripping impurities from belt bands in conveying systems in the area of a drive and/or deflection cylinder of the belt band. The inventive device comprises a system support which is fastened to a belt band-supporting frame and on which at least one stripping element is arranged. Said stripping element is provided with a stripping lamella that is mounted on a lamella support and leans in a stripping manner against the belt band in the stripping position. The stripping element is also provided with a lower rotating joint which is connected to the lamella support and has a horizontal rotating shaft, the term horizontal and similar in principle referring to the operational position of the stripping element, and a spring device that acts upon the lamella support in order to press the stripping lamella against the belt band. Said lower rotating joint and spring device are configured and disposed such that the lamella support is pivoted in a spring-loaded manner about the horizontal rotating shaft in the stripping position of the stripping lamella while slightly swiveling away and swiveling hack into the operating position on the belt band when obstacles which permanently stick to the belt band hit the stripping lamella. In order to be able to use the inventive stripping device at least as a preliminary stripper showing a regular stripping performance in the cylinder area of the belt band while obtaining extended operating times even at high belt speeds which are associated with correspondingly large quantities of material, the stripping lamella is pivotally mounted on the lamella support by means of an upper rotating joint having a horizontal rotating shaft and is maintained in a spring-biased position by means of an upper spring device, the spring effect of which is in the opposite direction relative to the lower rotating joint and the spring device thereof.

The present invention relates to a device for cleaning the scraper, which is in contact with the belt in the operation of dirt from the belt in the belt conveyor position, systems in the area of the main and/or leading bay, and in which the cleaning element includes a lower flap, a hinge, attached to the holder, and which has a mountain - - containing a traverse, which is attached to the frame umbrella pivot axis - the use of such a word, conveyor, as "horizontal" here and hereinafter refers to the head - - on which is located at least one operating position cleaning element, mentu - - cleaning element that has a scraper installed on the scraper holder,

- as well as an elastic means designed to then return back to the cleaning position by pressing the scraper on the holder to the belt in such a conveyor belt, exactly as it happens in the form and design of the cleaning device according to the prototype. However, - that the holder of the scraper in the working position according to the invention, the deflection of the scraper reaches - the scraper rotates around the horizontal axis and thanks to the new principle, when the lower support is a spring-loaded, spring-driven hinge of the holder interacts with - its when an obstacle that is firmly attached to the pins with the upper hinge on the holder, namely in the place of the tape, hits the scraper, the holder can slightly where the scraper is attached to the holder and at normal- deviate and then return to the working position of the cleaning operation, and when the scraper must be on the conveyor tape skip the obstacle on the conveyor belt.

In the prototype of a cleaning device of this type In the normal cleaning process, the homogeneous type EP 0 739 303 VI) the plate holder has a layer- the contact of the scraper with the front part of the belt of wells with a limited angle of rotation of this design, provides mainly the lower hinge due to which the scraper, which is in contact with the belt, can be attributed to the predetermined deflection force of the spring to changes in the inclination of the tape by means acting on the scraper holder. Top joint, tomato twist. The hinge, which contains the spring together with the upper spring means, the retaining means acting on the holder, consists of a scraper unit in the desired cleaning position under the torsional spring, attached to a variable cleaning angle of the scraper to the tape. In dependence - soul. In this prototype, a very quick result of the working conditions, equipped with a spring, is achieved. For cases where the contact of the scraper with the tape, which is essential for the tape to permanently or temporarily adhere to a large uniformly high cleaning capacity. Because of the amount of material to be cleaned, small inhomogeneities on the conveyor belt, the sensing device may be overloaded. In will cause a short-term lifting of the scraper, in such cases it is necessary to install the previous ones, in particular, with higher speeds, sometimes bringing- cleaners capable of cleaning from the tape large quantities or even to a longer time of return of the scraper in the hundred of material. working position on the conveyor belt, esp

A cleaning device used in the event that this is caused by only one as a pre-cleaner for the drum area, glass- spring-loaded means acting below. It is made of plastic blocks, which are usually installed. In unforeseen cases, in particular, when the scraper hits large obstacles, which are difficult to ry the tapes next to each other, each of the blocks is separated, both equipped with hinged springs. the cleaning edge and for cleaning can turners come into action and raise the scraper above the tape and press against the tape. Thanks to the elastic in a fraction of a second, so that the obstruction of plastic materials can be removed, the blocks can be removed under the scraper, as will be explained later. you are obstacles that stuck to the tape. However, when an obstacle firmly attached to the belt- the cleaning edges of the blocks are prone to severe wear, for example, so-called belt damage, and, in particular, break at high speed- hits the scraper, the scraper can easily leave the belts. In addition, the wear of the material to its place of cleaning on the conveyor belt. The cleaning edges of the scraper are very different, so the cleaning edges with their cleaning edge come into contact with an obstacle and reveal an uneven contour, and the cleaning edge is diverted to the side. This can lead to ober- ability is heterogeneous. tal movement around the rotary axis of the upper

Therefore, the purpose of this invention is to create a hinge in which the force of the spring, and therefore of the rotating device, which could be used in the zone of the melting force of the compressed spring means, of the conveyor drum, at least as the previous one melts. On this rotational movement of the scraper superimposes a cleaner with a uniform cleaning capacity and sia rotational movement of the plate holder around which could work longer even at high lower hinge in the opposite direction, which belt speeds, associated in particular with relatively caused by belt reaction forces transmitted by high by the amount of material that needs to be removed through the scraper. This leads to further warping in the drum area. improving the action of the spring of the spring means acting on

According to the invention, the goal is to reach the lower hinge in such a way that the turning force is also increased here. During this rotation, the scraper (8) is hinged on three movements, at the moment when the distance from the upper rotary scraper with the help of the upper hinge, which is the axis to the tape, increases to the distance has a horizontal rotary axis, and between the upper rotary axis and cleaning - is held by the upper elastic means, which sooner or later, the scraper begins to move away from is in a tense state and the action of the spring interacts with the obstacle, and the obstacle can pass through - in relation to the lower hinge and its you under the scraper. of an elastic means - directed in the opposite direction A sequence of two rotational movements in the direction are placed one on one, significantly depends on

The cleaning element of the cleaning device has many forces, in particular in the area of the scraper and the upper structure according to the present invention, characterized by a hinge, including an elastic means operating there, and by the fact that the holder on which the scraper is installed, from the resulting torque, which can easily to deviate when an obstacle that mit- this arises. The smaller the number of these components stuck to the tape, hits the scraper, and can tives, that is, the components in the upper part of the holder,

the faster and, in particular, the easier the scraper can react to the impact of obstacles, i.e. move back. during the course, preference is given to torsion bushings, which

In particular, for conveyor belts that quickly have a relatively large deviation angle, in both - and move, and a large amount of forces, as well as in the upper and lower - hinges, because the upper slope depends on the size of the obstacles that stuck to the belt should be as close as possible to the belt, the belt, rotating around the lower hinge tri- so that the rotational movement of the scraper has as little as possible the scraper that was caused by the impact of the obstacle at the moment of inertia. For the lower hinge, the scraper may still be in progress, or the return is also kept as large as possible. scraper in the opposite direction around the top- To use the well-proven features of its hinge, which depends significantly on the quick- application of torsion bushings and in addition to reach a hundred tape, has already ended, or is ending. At the largest possible angle of deviation, in this case, the return of the scraper to its working position on the holder may occur so quickly that the scraper will not be located on the conveyor a square element and the tape corresponding to it with its cleaning edge, and directly with the square body, which contains elastic elements, with its angular cleaning surface.

Due to the design of the scraper according to the invention and two separate torsion springs, elastically connected to its functioning in a normal cleaning operation, they are connected to each other in series so that the full re obstacles, such as damage to the tape, for the sum of the deflection angles of individual torsional front wipers, it is possible to achieve an unusual spring (item 4 of the formula). cleaning efficiency. Special suitability for the use of eye-

The use of the proper geometry of the cleaning feeler device according to the present invention, the element according to the invention, as will be explained later, is monstrous with a torsion sleeve, in which three separate torsion springs, starting from the installation of the cleaning device, are installed next to each other continuously until the very final wear of the scraper is not sweaty. internal square rod, have an additional regulation function, i.e. the pressure of the scraper- separate housings and spring elements and form the tape remains constant. This means that the cleaning device according to the present invention uses a double spring, that is, such a torsion spring, which has a double deflection angle and in which two sides do not require maintenance. their bodies are rigidly fastened and form one

In addition to the relatively high and uniform cleaning end of the double spring, while the average housing capacity, the cleaning device according to the data represents the second end of the double spring (item 5 of the invention also has an advantage in terms of the best formula). preservation of the tape, because the scraper can easily be removed. The above-mentioned double spring is built and protected from damage to the tape or something similar. For the same reasons, the invention also allows the holder, which is used for the connection between the lower and upper torsion bushings. made of steel, ceramic or something similar, which has an upper torsion sleeve, designed to maintain its shape, and based on the perspective of a double spring and with its lower end guarding the surface of the tape - homogeneous and attached to the middle body of the lower torsion normal cleaning ability. bushing, designed in the form of a double pro-

The elastic device, which, together with the bottom hinge of the gimbal, while both side bodies are attached together to the holder, can be a mechanical spring to the scraper plate (upper torsion sleeve) of the gimbal for stretching or compression, or even hydra- and to the sole ( lower torsional bushing) of a cleaning mechanical means or something similar. According to the element (clause 6 of the formula). Please note - by further development of the invention, it is preferred that this arrangement can also be converted to a torsion spring, which is connected to both - rnuto, that is - depending on the design requirements - the lower and upper - hinge, or with only one of the levers of the holder can also be connected from the upper ones (item 2 of the formula). and/or the lower side casing of the torsion spring

Accordingly, the upper and/or lower hinge sconces. such a torsion bushing can be used, in particular - a rubber torsion bushing (item C for- as a lower and/or upper torsion bushing and thanks to the mule), because it has been verified that this combination of a hinge and the use of known the advantages of the rubber torsion spring itself is suitable for cleaning the torsion spring can be easily assembled in devices for conveyor belts thanks to the extrinsic, and in it, in addition, thanks to the design of the roll and the long service life of such torsion-double spring, it is achieved the doubling of the amplifier bushings, as well as due to their compact design, the maximum deflection of the spring. Such shares. thus, a double deflection angle is achievable for the torsion sleeve.

The double spring also has the advantage that the edge of the scraper is on the side of the drum, and the upper axis changes the force of the spring when the hinge is deviated by a certain angle from the side opposite to the drum, less than the maximum force of the spring, even on the side of this plane (item C of the formula). Thus, within the limits of a relatively small angle of deviation, and the change of nom, the scraper holder is installed in a place near the force of the spring per unit of the angle of rotation is, from where after the impact of the obstacle on the scraper, it can be seen, large. Thanks to this, the operator can quickly react and deviate. With this cleaning element according to the present invention, the aim of the lower hinge axis is the following advantage: in all conditions, the important is achieved on or near the tangent plane (a point of sufficient deviation to create a pressure force for formula 10). scraper However, it has been proven that for the functioning of the upper pressure within the wear angle, i.e. in the area of the hinge angle, it is useful if a relatively long deviation by which the scraper holder moves to the grain of the plate holder allows the scraper at the impact of full wear. obstacles are easily deflected. Therefore, in

Preferably, the working line of the cleaning edge until the further development of this invention of the scraper in the working position of the scraper on the conveyor between the upper and lower hinges should be the tape passes anywhere in the lower 90" is chosen large enough so that the angle for the sector of the contact angle of the tape with the drum between us, the deflection of the spring means associated with the horizontal and vertical central lower hinge, and the angle for the amount of deflection by the planes - in particular, in the place oriented, as the plate holder around the lower pivot axis is said, "at three o'clock" (clause 7 of the formula).

Therefore, preferably the working line is located in the total value between 40" and 80", however, preferably in the zone, behind the belt, immediately after the point 65" in the sum (paragraph 11 of the formula). of the discharge of the transported material. Thus, when assembling the cleaning device according good access to the cleaning device is provided by the invention, while the space below the adjacent sector is left free for other purposes in the desired location of the scraper. In addition, the plate holder sleeps. That is why, according to the material, cleaned from the tape, remains close to the invention, it is desirable that the working position of the scraper is the collection point of the transported material. as they say, for three hours. of an elastic agent connected with it, and fixed with

According to the present invention, the cleaning posi- with the help of an adjusting screw or gasket, the scraper on the conveyor belt in conditions of speed or something similar (item 12 of the formula). the deviation of the scraper when hitting an obstacle can, when setting the desired position of the holder, in addition, be located anywhere in the end relative to the tape, it is necessary to carry out the corresponding stroke angle, that is, in the upper 90" sector, and to adjust the position of the holder on the traverse . even if there is a need for this, under the lower 90" To implement this, it is appropriately deflected by the sector. Such a wide range allows, if the force of the spring means, acting in the lower part of the hinge, to be installed in a row in the front part of the stream, is adjusted by means of the corresponding kidney, two or more cleaning devices. gate of the holder by the amount of the required displacement

At the same time, the axis of rotation of the lower hinge and fixation of the holder in the deflected position rests mainly on a circle drawn around the butt, using a separate adjusting axis of the drum, and accordingly, the axis of the upper hinge of the screw or with the help of a gasket (item 13 for- is also located on such koli. Like the inside of a mule). After such a separate adjustment, it is located between the tape and one, the holder and the cleaning element of the traverse by the outer circle, which is determined by the possible approach to the tape until the cleaning edge of the lower hinge. the scraper will not take, accordingly, the given working

For the cleaning arrangement of the scraper on the bed and an effective line. Then, accordingly, the conveyor belt is allowed to release and turn back the screw so that the invention works and according to the following development of the given force of the spring and the scraper properly presses the invention, it is desirable that the angle of attack of the scraper is all to the belt. the working position on the conveyor belt was in As a possible option, in accordance with the range from about 40" to about 80" a relative development of this invention, the installation of a plane tangent to the belt on the drum, in the scraper in the working position on the conveyor belt point of the working line of the cleaning edge of the scraper, completed by the appropriate rotation of the blade holder, however, it is equal to 60" (item 8 of the formula). protecting elements around the lower hinge,

The angle of attack in this area determines the high cleaning ability, which is accompanied by the deviation of the corresponding lin capacity and at the same time allows the spring means to quickly remove the scraper by adjusting the traverse when the tape is damaged (item 14 of the formula). To adjust the traverse, something like this hits the scraper. different systems can be considered, explained below.

In particular, when the working line of the cleaning edge First, the adjustment and deviation of the scraper holders is located in a place oriented to the three can be carried out by moving the travers- hour, as well as for positions that are si (paragraph 15 of the formula). After the movement, i.e. below, it is beneficial for the axis of the lower hinge to be in a predetermined position relative to the plane tangent to the belt, and therefore the cleaning edges of the scrapers reach the drum, at the point of the effective line of the cleaning its working position and their effective line is on the tape, the traverse is mostly fix- Fig. 3 shows a side view of the element, similar to It is also possible to allow the force required for the element in Fig. 2 installed in the working position to achieve this position, continues position, and additionally shows the scraper in deviations to act, for example, by using a strong position after contact of this scraper with springs or something similar. an obstacle firmly attached to the tape;

Preferably, the movement of the crossbar in the horizontal direction Fig. 4 shows a schematic side view of the ram in the case of installing an effective belt with a tape to demonstrate the possible line of the cleaning edge in particular in the position of the cleaning elements relative to the ram, oriented "on three hours" (clause 16 of the ban; formulas). The location of the traverse under the effective Fig. 5 shows a similar schematic view of the scraper is a prerequisite for all options on the side of the cleaning element, as in Fig. 2, which has a location. in each, upper and lower, hinges eye-

According to the first version of the traverse, the torsion springs of the pushing element, in particular, are fixed at both ends directly on the brackets - a demonstration of the torsion bar supports used (item 17 of the formula). According to the second option, we use springs and large angles of deflection of the holders (item 18 of the formula), the traverse is attached to both cleaning elements, which thanks to this become ends to rigid supports, each of which can be fixed; on the bearings, which allow their horizontal - Fig. b is a front view of the cleaning element ly shift, installed in the center of the zone, or on Fig. 5, shown in a section along the C-O line at the height of the horizontal axis of the drum and on the horizon - Fig. .5. sliding bearings. According to the third variant, Fig. 7 - cross-sectional view, additional to the volume shown (item 19 of the formula), it is provided that the traverse in Fig. 5, given to illustrate the design of the torso, is attached at both ends to rigid supports, a double spring according to with the following development are horizontally sliding with the help of the sub-tissue of this invention; bearings, each of which is installed above the mountain. according to Fig. 7, for an undeformed torsion spring

Instead of shifting the traverse for adjusting the opening; adjusting elements or plate holders can be Fig. 9 - side view of the structure shown in Fig. 7, as well as in Fig. 8, which demonstrates the deviation of the traverse. For this, it is desirable that the traverse of the casing located in the center of the torsion spring is installed below the working line of the scraper, and for partial rotation of the structural element, the external installation of the traverse is carried out by its rotation of the casing of the rubber torsion spring, as well as rotation by applying a rotary continuous internal square moment element to the traverse itself or to its hinged all three bodies; bearing (item 20 of the formula). The rotary motion can be generated pneumatically, hydraulically, by the cleaning element touching the conveyor or mechanically by stretching, squeezing or drum in the position positioned "at three o'clock" by the torsion of the springs, or by the force of weight, or by something in the front part. tape, and which is installed on a similar (paragraph 21 of the formula). traverse, which has a sliding support for displacement under

Due to a small change in the angle of rotation, the force of the side in the process of cleaning is in close contact with the strip-spring Ry changes very slightly and the remaining and its cleaning edge 9 in position, is oriented almost constant.

The density of this contact is determined by the force of the spring Ry, if in this case it is achieved by the force of the spring Ry, with which the holder holder 7 occupies the position shown in Fig. 2 as 7 presses the scraper 8 against the tape 1, moving 7". Such a situation may arise when an obstacle around the horizontal pivot axis 13 lower-H, which is tightly attached to the belt 1, such as, for example, the hinge 11. In the typical implementation shown here, damage to the belt, or something similar, hits the lower hinge 11 contains a torsion sleeve 15, the cleaning surface 8. the operation of which will be explained on the example of Fig. 5-9. From Fig. 2 and 3 it can be seen that the scraper 8 is installed on

The torsion sleeve 15 is connected to the traverse 4. the upper end of the holder 7 with the help of equipment

To create the force of the spring Рy, with which the spring of the upper hinge 12, which has a scraper 8, the holder 7 presses the horizontal rotary axis 14 firmly enough. For this, it is varied to the tape 1, the holder 7 is deflected by an angle of 40" in this implementation, when the upper hinge 12 is equipped with a spring from the neutral equilibrium position of the lower hinge, the torsion sleeve 16 of the analog torsion sleeve 15 was selected, in which the holder would occupy a hinged structure, as for the lower torsion sleeve position 7, for pressing the scraper 8 to the tape 15 The torsion spring of the upper torsion sleeve 1 until the holder 7 actually takes the position 16 is deflected so that the spring force Go for the torsion sleeve 15 shown in Fig. 2 when acting as shown in the clockwise direction of the spring force Bi can effectively create and arrow, precisely in the opposite direction to relatively maintain close contact of the scraper 8 with the tape of the force of the lower spring Рy, the magnitude of the force Го fic- 1.

After that, the holder 7 can, as will be explained later, pass to the release so that the force of the spring Рy starts acting under the scraper 8 and provides the necessary contact pressure scraper The scraper 8 touches the obstacle H with its 8. The working position shown leads to the cleaning edge 9 and is deflected. It rotates so that the dirt stuck to the tape is removed, scraped around the rotary axis 14 by the upper pivot 8 with the cleaning edge 9 and then removed. ra 16 in the counterclockwise direction, in that

According to the second option, the deflection of the holders 7 as the force of the spring Po, and therefore the turning force of a number of cleaning elements 6 and the installation of the twisted torsion spring of the upper torsion bar 8 is carried out by approaching the traverse of the sleeve 16, increases. This rotational movement of the scraper 8 4 together with the cleaning elements 6 to the belt 1 and is covered by a rotational movement in the opposite direction by pressing them together with the traverse 4 to the direction of the holder 7 around the lower torsion belt 1 until the scrapers 8 are installed in the robotic sleeve 15 , which is caused by the opposing forces of the position on the effective line of the MU. tapes 1, which are transmitted through the scraper 8. At the same time, the elastic pressure of the lower torsion sleeve 15 further increases so that it also increases with the rotating rod (the external structure of the case body is not strong. After all, during this rotary applies) attached through the soles 30 to the tra - movements in the opposite direction of the holder 7 and the scrubber 4 (shown purely schematically in Fig. 7-9). ka 8 the distance from the upper pivot axis 14 to Between both side casings 22, 23, coaxial with the tape 1 becomes the same as the distance between the upper ones, a central casing 24 is installed, which has a pivot axis 14 and a cleaning edge 9 - except in particular the same the internal cross-section, as well as the side, must take into account the dimensions of the obstacle H - the housings 22, 23. The internal square rod of the scraper, as shown in Fig. 3, can move away from the pe- 25 passes through three housings 22, 23, 24 . as shown in the figures, the scraper 8 has a rotation angle of 51" against the force of four elastic, foam springs Ео in a compressed state, and the rotational movement of anti-reverse rubber elements 29. In the central, reverse direction of the holder 7 to reaching the corner of the casing 24 there are two groups of four elastic turning elements 9" and is in the position indicated by 29, located next to each other, so the whole as 7, the structure contains four groups.

In the introductory part of the description, it was already mentioned that it is well known about the use of rubber reverse movement, as well as the return of the scraper 8 in torsion spring elements in the presence of internal working position, the faster the square rod and body, the smaller the mass of the components in the upper part held in such a way that at least one of its inner parts 7. The task of the scraper 8 is to settle into the position of the surface has a square shape with rubber elastic elements installed in the angle of attack before it returns to the necessary corner zones, the position of the holder 7. Thus, the return in particular - in cleaning devices for conveyors, the scraper 8 is in the working position on the holder 7 of the tapes. However, the construction and connection of the described should occur in such a way that the scraper 8 begins to touch both side casings 22, 23 and separate them from the tape 1 not by the cleaning edge 9, but by the middle casing 24 with its common release cleaning surface 10. This requires all three on the inner square, in order to achieve the best possible preservation of the current of the rod 25 and determines the peculiarity of the design of the chka and the smallest possible interruption of the process of the clearing bushing 15, which has two external torsion bars. the springs in the side casings 22, 23 are rigidly connected

Possible implementations of the cleaning device with each other, in this case - through the traverse according to the presented invention, are shown in example 4, while the central torsion spring in the middle

Fig. 4, near the drum. It turns out that the casing 24 described by him can rotate freely relative to the action of the cleaning device according to the invention of the side housings 22, 23. Since the inner quad is not limited by the position of the scraper 8 near the tape rod 25 is not fixed, but freely "plate 1, oriented for three hours, but any wobble" and is held only by elastic elements, the place of the contact angle of the tape 1, which is located 29, the inner square rod 25 can rotate in its upper or lower 90" segment relative to all three bodies. If, for example - to be considered suitable for the location of the working stock, the holder 7 (in Fig. 7 shows only the schematic position of the scraper 8, and there is even a possibility), attached to the outside of the middle casing 24, to install the scraper 8 in the working position, which (compare with Fig. b) , rotates by 30", the inner one is outside the lower 90" segment, the square rod 25 rotates only when the contact angle of the tape 1 exceeds 90" and for 157. Deviation t the orsion spring also corresponds to the cleaning device, there is a need for a remote deviation of 157. So, thanks to the given location of the cleaning place. Such a large design, the angular displacement of the holder 7 represents a range of possible cleaning places allows the insertion of a doubled deflection of the torsion spring, as shown in Fig. 9. In the deflected position, three or more cleaning devices, as indicated by 7 in Fig. 5, the side casings 23 show a corresponding angular displacement relative to the but in Fig. 4 for three additional cleaning devices of the central body. devices in different places around the drum, which can be seen from Fig. 5 and 6 that the designs are marked with the symbols 6", 6" and 6", and the devices of the illustrated torsion sleeve 15 and the upper torsion sleeve are indicated by dashed-dotted lines . Each pivoting arm 16 - the holder 7 connects them - are the same and equally the axis of the lower torsion bushing 15 is at work. In both cases, the double design of the outer circle 21, and each pivoting axis of the upper spring enables large deflection angles. As it torsion bushing 16 - on the inner circle can also be seen from Fig. 7, both side skins - relative to the axis of the drum. x 22, 23 are rigidly attached to the plate 31

As an example, Fig. 5-9 shows a typical implementation of a scraper, and therefore one to the other, while the center of the original design principle of the torsion sleeve is the body 24 of the middle torsion spring, which is for the torsion sleeves 15, 16, the principle is functionally rotates, rigidly attached to the drive of which is explained further on the example of the lower shaft 7. torsion sleeve 15. To install the traverse 4 on the frame of the belt

From Fig. 6 in combination with Figs. 7, 8 and 9, it is possible to see the conveyor unit and the adjustment of the cleaning elements, which are used to create the so-called double torsions 6, which are supported by the traverse 4 near the belt spring, the left side casing 22 and the right side chki 1, there are several possibilities, which will be light casing 23 firmly connected to the square inner len in the example of Fig. 10-15 in combination with Fig. 1-3, and which, to serve as a typical example, should be in different ways. So, for example, the installation is explained. scrapers of 8 cleaning elements can be carried out

First, the scraper 8 is installed in the desired position by shifting the crossbar 4 using the horizontal working position by rotating and deflecting the laterally sliding support 32 in the direction of the arrow P of the upper torsion sleeve 16 and is fixed in this under the drum 2, as shown in Fig. 10. From Fig. 11 position (separate adjustment). it can be seen that the central support of the traverse 4 for

Then the desired position for installing the scrapers 8 is set in a place oriented "on the three holders 7 relative to the tape 1. To do this, hours" can also be implemented with the auxiliary sleeve 15 is adjusted or prepared by the rigid support 33. by the appropriate deviation to the desired angle In this case, the horizontal plane under (compare Fig. 2 and 5) the holder 7 and by fixing the bearings 32 can also be above the horizontal holder 7 in a deviated position, for example, the axis 34 of the drum 2, as shown in Fig.12. by using the adjusting screw or Fig. 13-15 are all examples of the rotary support of the gasket. After this adjustment of the holder 7 of the crossbar 4 for installation and pressing of the scrapers 8, the crossbar 4 is brought closer to the tape 1 until the cleaning of the holders 7 of the crossbars 4 shown for the case of the rising edge 9 of the scraper 8 does not reach the set working position of the scrapers 8 in the working position, approximately - what is the position on the effective line M/. Then the screw is turned "for three hours". In Fig. 13, where the traverse 4 can be released or turned back in such a way, it is installed in the area under the drum 2, the traverse so that the force of the spring of the holder 7 can act and the scraper 4 is set in the working position by 8 being pressed against the belt 1, for example in place , rotation or rotation when applying rotationally oriented "for three hours", as shown in the last moment to the very traverse 4 means of pneumatic implementation. matrix, hydraulic or mechanical, spring

Instead of the individual deviation of each holder, we stretch, compress or twist, or 7 or the lower torsion sleeve 15, this is regulated by weight, or something similar. In Fig. 14, matching, according to the second option mentioned above, but with the first option, the torque can also be implemented for a whole series of cleaners below the horizontal axis passing through the elements b in general by their approach to the center of the drum 2, in in any case thanks to the tape 1 and pressing against it with the help of tra- bearings that are at a distance to this version 4. axis on both sides of the traverse 4. In both cases

The approach of the crossbar 4 to the drum 2 with the torque causes a rotational movement by pressing the scrapers 3 of the cleaning elements of the crossbar 4 through the rigid side supports 33, which, located on the crossbar, can support the crossbar 4. and more
