Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that is installed at the bottom of a belt conveyor O-belt, and scrapes off residual conveyed material with a scraper to clean the belt. Regarding conveyor cleaning equipment, it is conventional)
Various products have been provided and put into practical use. First of all, when it comes to the material of the scraper used to scrape off the adhesion-resistant residual water, 0*m metal such as tungsten carbide and aluminum-based 12-metal scrapers are often used. There is. The former has a high degree of cleanliness and is highly adherent! The lifespan of the pigeon coops used is extremely short. The latter has extremely high hardness and long service life due to the extremely high hardness of the metal, but has the drawback that it is prone to cracking during transportation or cleaning, and the sharp edges caused by the cracks can damage the belt.

In addition, the scraper has a single blade that corresponds to the required belt width. A support shaft KIR is attached to the support shaft, and in order to fix the support shaft, it generates an oypHo pressing force to the base/ray AO belt.

tOa due to the rubber cutter, ** above the Pumutatsushi seal, the scraper O fluctuation tracking is allowed at a number of l1jlL or at.
<Confirmation of contact pressure is also ll1jIl.

Since the belt surface 111 moves irregularly up and down, it is not possible to keep the scraper in close contact with the belt at all times. The leaf spring type and the expanded heavy hook type are able to follow the up and down movement of the belt surface up to several dozen square meters, but the up and down movement of the belt is irregular. It is difficult to bring the belt into close contact with the metal body.

To the east, these cleaning devices are installed on the transport side of the belt, that is, on the underside of the belt, with the scraper facing upward, and have a structure that applies pressing force to the scraper against the belt.
The support means and support shaft of the scraper are generally arranged at a position where the material scraped off by the scraper falls.

For this reason, the scraped material accumulates on the support shaft and the support shaft, and reaches the surface of the support shaft, which in turn lifts the belt surface and extremely rarely damages the cleaning result. On the other hand, the pressure caused by the accumulated material often causes the support shaft to bend downward.

The purpose of the present invention is to follow the irregularities of the belt, always keep the scraper in close contact with the belt, have good cleaning efficiency, have a long scraper life, and eliminate the risk of damaging the belt. We provide a belt cleaning device that prevents scrapings from accumulating on the support axle.

The cleaning device for this belt conveyor is installed at the end of the belt conveyor, and uses a scraper to scrape off the conveyed material that remains on the belt. The cleaning device is characterized by having the following components -) to (e).

(a) A steel scraper that is divided into multiple parts and has two pieces of steel on both sides.

(b) A support shaft that is provided parallel to the belt surface and perpendicular to the conveying direction, and can be maintained at the required plow position.

(,) The armpit support shaft KIl is equipped and can be fixed at the desired rotational position), and the same number of short tubes as the scrapers.

(d) An il spring that is wound around the short tube and has one end locked to a stopper provided on the short tube.

(・) It has an arm and a stopper for fixing the scraper at its tip facing the belt, and is fixed to the OII small tube on the 41A side of the coil spring by engaging the stopper with the other end of the coil spring O. holder ring.

The cleaning device for a pair of belts according to the present invention rotates each of the short tubes, brings the width of each scraper 10 into contact with the belt, fixes each short tube to the support shaft, and then fixes the support shaft to the support shaft. By fixing the coil by moving it in the unwinding direction of the spring, a restoring force is generated in the coil spring, and the scraper tip is pressed against the belt by this restoring force. It is a device.

Other aspects of the actual device are detailed below.
It would be obvious that he would be criticized by himself.

Hereinafter, the apparatus of the present invention will be described in detail based on examples. Fig. 1 is a schematic side view showing the situation of several lines to the belt conveyor of the OSm example installed in Honjitsu 11101, Fig. 2 and Fig. 3 are a schematic plan view as seen from the arrow in Fig. 4m1, 211th W-W @ 5w1m, 1II Klok track tube and anti-corrosion cover; 6th wJ is the holder ring At the Seiwa Garden.

As shown in No. 111, the apparatus 100 of the present invention is installed on the return side of the belt conveyor 20 of the belt conveyor 20. In the 1st E, 22 is a lap pulley and 23 is a snap pulley.

In No. 1 to No. 411, 1 is a scraper for scraping off transferred objects that adhere to the belt 21 and are resistant to residual noise.In the device of the present invention, the scraper 1 is divided into a plurality of pieces, and both sides are sandwiched between steel plates or the like. -ky (The main feature of the -ky is that it is similar to the board. By dividing the scraper 1, the belt 1 can follow the harmful birds even if the belt is not connected properly. Also, the scraper 1 can be It is difficult to keep the scraper (1) in close contact with the belt even if it is worn out.The width of the divided scraper (10) should be made narrower so that it can be used for better employment. It is considered mtL to provide pressure contact means to the belt for each A, but unnecessarily increasing the number of scraper tips will complicate the structure and make it difficult to manage. It is not a good idea to make the width of the scraper narrower than it should be, and the method of crimping each scraper to the belt becomes a problem. Only then can it be effective.

In this actual MO device, the width of the line scraper 10 is 80 to 15
0, preferably about 100 proverbs. Also, since this scraper] < 1 O@ll'1-41 power supply @ 0 manpower 0 ease of use also depends, the distance between the scrapers 1 and 1
When using a 0.00 mm width scraper and the crimping means of the present invention, 1 mm width is sufficient. Since attached equipment is installed near both edges of the belt snow 1 of the belt conveyor 20, it is generally difficult to press the scraper against the belt width metal body. According to the example, 100 mg@0 scrapers are used in the number shown in Table 1 for each belt width.

As shown in Figure 4, it consists of a ceramic plate, such as a heavy electrical equipment board I, and stainless steel plates IB and IC sandwiching it on both sides. . - In the example, the thickness of the ceramic [IAO is 3, the thickness of the outer stainless steel plate IB is 3-1, the inner stainless steel plate I
The thickness of C is Im. These three plates are firmly glued together, stainless steel 1 [IB, IC is ceramic plate I]

Since it is recessed into the IC, the belt will not be damaged by the hem. Scraper 1 is Ryutsu Z Tsukusu 1 [If IA is worn out, it must be replaced, and ceramic plate IAK
Since it is troublesome to make a hole in advance, the vicinity of the attachment part of the scraper 101 to the arm 9B is replaced with a stainless steel plate 10.

As shown in FIG. 1, the present apparatus 10 is provided with a support shaft 2 parallel to the bell 2111111 of the belt conveyor 20 and perpendicular to the conveying direction of the belt 21.

The support shaft 2 is a belt conveyor, as shown in Figures 1 and 3.・The O base part (Il not shown) is Km* and is mounted on nine angles 3 and supported by nine bearings 4. Further, the bearing 4 is provided on the angle 3 and bolted to nine long holes 5, and is connected in the vertical direction in FIG. 3, that is, the support shaft 2 and the belt 2.

After moving the screw to the yytttto position, tighten the bolt 4A to fix the support shaft 2, and the device 100 is ready for use.

The number of support shafts is 2Ka, the same number as the number of scrapers 1 (it has 4 rotors in one embodiment)! Each short tube 6 is fitted with a small tube 6.
The tightening pole) 6A is placed on the foot, and the 6 tightening bolts are tightened. This makes it easier to fix the short tube 6 in any desired surrounding position. Of course, *the support shaft of the small tube 6 The position of No. 3 in the axial direction is one end Ol! The small tube 6 is positioned in the appropriate position relative to the bell) 21. ! I [The length of the small tube 6 is the scraper 11c! Width〉1 to number ■ (l■ in the lI example)
Since it is a short comb, each scraper l can be held at an appropriate position and in a correct posture by sequentially placing the working short tubes 6 next to the nine short tubes 6 on the support shaft 2. Referring to FIG. 5, the stopper side I[7 is melted at one end of the small tube and is integrated with the short tube.

At this time, make sure that the scraper 1 is in contact with the bell 21 at an approximately right angle or at most an acute angle, and avoid making an obtuse angle with the support shaft 2 and the bell).
! If the distance between 14D and 14D is adjusted to an obtuse angle, there is a high risk of damage to the scrap Al or the belt 111.

When the adjustment of all the short and small tube sogw movement positions is complete and the movement position is round, loosen the bearing 40 of the support shaft 2, make the support 3 movable, insert the par into the hole, and lever the bar. As a result, the support axis will be moved to the left 11DKIl in the first cabinet. The tip of the scraper 10 is in contact with Bell) 21KIi (or already in contact with Kll), so]
When power is applied, the position of scraper 1 does not move due to heavy weight (
Actually, it moves slightly with Bell) 210 Ewami. ) Since the support shaft 3, and therefore the short tube 6, are moved to the left, the coil spring 8 is unwound. In this state, when the support shaft 2 is fixed with the bolt 4, a restoring force is generated in the coil spring.
1. This restoring force is proportional to the coil deflection angle, and this angle is the dust force, <-1xo
It can be clearly read from the angle 10A of the N needle 12A and the side plate 10.

As a coil spring, coil l16 lu■, wire 417■
In one embodiment using a coil spring with 7 closely stacked coils, a 1330 kF peak is generated at the scraper tip by unwinding the 4S coil spring, i.e., 6. It is possible to generate contact pressure of 8 cicadas.

The features of the device of the present invention which is constructed and operates as described above are summarized as follows.

(Since the scraper is composed of ceramic plates sandwiched between corrosion-resistant steel plates on both sides, there is little risk of damage or cracking. Even if the temporary scraper cracks, there are four layers of corrosion-resistant steel plates on both sides.) Since the ceramic plate maintains the original engraving, it can achieve the same scraping effect as a crack-free ceramic plate without damaging the belt.In addition, since it is protected by a corrosion-resistant steel plate, the ceramic plate can be removed without damaging the belt. [K scraper is divided and pressed against the belt by appropriate elasticity of the coil spring, so the pressure contact force can be small. The lifespan of high-quality ceramic plates can be significantly extended.

(2) The scraper is divided, and each scraper can be adjusted to the appropriate position with respect to the belt depending on the change in WIO of the belt and the difference in the wear of the scraper IIO. Therefore, in order to improve the four-dimensional property of the belt, it is possible to open the support shaft of the metal scraper at the same time and keep the scraper constant at the same time. It slows down because of the pressure.

In addition, each divided scrape A@ is narrow and is pressed with the elasticity of an appropriate coil spring, so it can fully follow the wide range of upper and lower O movements of the belt with little pressure contact force, and always maintain a stormy fourth floor. It is possible to hold it.

(3) A steel bar is used for the support arm of the scraper,
The attachment part to the support shaft is covered with a cylindrical dust-proof pipe and a dust-proof cover, so even if the belt's adhesion-resistant residue is scraped onto these parts with a scraper, it will not stick and will slide. Therefore, there is no chance of accidents due to accumulation of scrapings as with conventional equipment.
Force #411 Due to the fact that the fourth floor to the spider belt is strong, this pressure contact force is small, and the coil is in pressure contact due to elasticity), the belt surface is
This will allow smooth passage through the center of the 311th township.

As described above, the belt tone bear cleaning device of the present invention has the following features:
It follows the irregular movements of the belt and allows the scraper A to be placed well on the belt at all times, increasing the cleaning effect, prolonging the lifespan of expensive ceramic scrapers, and eliminating the risk of damaging the belt. Since there is no scraping and no scrapings accumulate on the support shaft, etc., the value for m Tojo oH is extremely large.
