Definitions

the present invention concerns a device to clean screw-type tools, for example drills with a continuous screw used to drill the ground, lay pipes or otherwise.
the device according to the invention is able to remove the material and detritus which remain retained between the profiles of the screw, particularly, but not exclusively, during the drilling of clayey ground.
the invention also concerns the method to clean a screw-type tool which uses the device.
Such conventional devices normally consist of a non-motorized scraper element, that is, arranged idle on the plane of the spirals of the screw.
the scraper element exploits the component of tangential force, resulting from the reaction orthogonal to the plane of the tool, to follow the translation of the screw and rotate in order to keep itself at the same height, in such a manner that, following the movement of the screw, it does not interfere with the drive members of the screw or the ground, and can perform its cleaning action.
the state of the art includes a motorized cleaning device able to cooperate with a screw when the screw translates axially without rotating.
This cleaning device has a scraper element associated with motor means which make it rotate at a speed synchronized with the speed of axial translation of the screw.
This conventional device has the disadvantage that it needs the attention of an operator to manage the drive of the motor, particularly to guarantee the perfect synchronism (which is practically impossible to obtain without a continuous control in feedback) between the rotation of the scraper and the linear movement of translation of the screw.
the cleaning device is also subjected to a movement of vertical translation, this can create damage to its supporting structure and/or interference with other apparatuses in the vicinity, and in any case does not ensure an efficient cleaning action.
cleaning devices of a conventional type are vertically movable along the longitudinal axis of the tool. This disadvantage does not allow the device to be attached to various rotation heads.
a further disadvantage of cleaning devices of a conventional type is that they are mainly specific for particular types of screw; therefore, in most cases, every type of screw requires a specific cleaning device, which entails long times and high costs to replace and prepare the cleaning device which is suitable for the specific screw.
EP 0 844 364 A2 discloses a cleaning device for screw-type tools comprising a non-motorized scraper element placed, in use, between two adjacent spirals of the screw.
This scraper element is associated to a support element slideably mounted on a bar; the support element is comprised between two helical springs associated at their ends to respective force sensors.
the scraper element is subjected to an upward or downward movement with respect to the spirals of the screw. This movement can be detected either visually by an operator or automatically by the detection of the force sensors associated to the helical springs.
the rotational or translational speed of the screw is modified to restore the balance in the movement of the screw so as to maintain the scraper element in its correct and possibly fixed position between two adjacent spirals of the screw.
This solution is rather complex and scarcely reliable because the correction of the position of the scraper element with respect to the screw is not carried on directly but involves a regulation of the movement of the screw itself which is difficult and slow to reach. Moreover, this solution entails a complex and expensive regulation circuit due to the necessity to finely control the amount of the values of correction of the speed of the screw to first restore and then maintain the correct position of the scraper element.
the cleaning element can not be used when the screw is only rotating, or only translating, because the cleaning element is not provided with own driving means and therefore cannot follow such a movement of the screw maintaining itself between two adjacent spirals.
this cleaning element has the further disadvantage that, during the cleaning step, the screw must be rotated in the inverse sense (i.e. in an unscrewing sense) when is extracted from the ground; this can entail the detachment of material from the tip of the screw and the fall of this material in the hole just made.
the purpose of the invention is to achieve a cleaning device for screw-type tools which does not need the attention of an operator to be activated and to function, and which is not affected by the irregular and unbalanced action of the forces and frictions at play, or the size of the tool and/or the shape and pitch of the screw.
Another purpose is to guarantee that the cleaning element is subjected to minimum axial displacement even when the tool is translating, thus ensuring that a substantially fixed vertical position is maintained without requiring any control of the synchronism, which is difficult and expensive to do, and without requiring a fine control of the balance in the movement of the screw tool.
a further purpose is to provide a cleaning element which is able to be used also when the screw tool is only rotating or only translating.
Another purpose is to guarantee that the cleaning element maintains, during its action on the screw tool, an axial position substantially fixed with respect a point of reference, which can be fixed or movable, for any combination of the rotational and translational speed of the screw.
the cleaning device for screw-type tools is provided with at least a cleaning element consisting of at least a scraper element associated with support means.
the scraper element is suitable to be arranged, in use, between two spirals of the screw, so as to remove, in association with the rotary and/or translatory movement of the tool, the material retained between the spirals.
the scraper element is associated with own motor means which make it selectively rotate around the axis of rotation of the tool.
the cleaning device comprises sensor means able to detect a movement of axial translation of the cleaning element, in one direction or the other, with respect to a nominal working position, in relation to a displacement caused by the translatory movement of the screw not balanced by the rotating movement.
the sensor means are suitable to condition the drive of the motor means, in terms of the direction and/or speed of rotation, so that the scraper element directly follows the movement of the tool and remains in a substantially constant vertical position, delimited between two pre-determined end positions, and eventually related to a point of reference of the machine on which the screw is mounted.
the cleaning device comprises linear guide means able to allow the cleaning element, consisting of the scraper element and its support means, to translate linearly for a short travel defined between said two end positions, according to the direction of movement of axial translation of the tool.
the guide means in a preferential embodiment, consist of column elements solid with a support, such as a feeding head for vertical tubes or a slider.
the sensor means comprise feeler means of a mechanical, optical, magnetic or other type suitable for the purpose.
the feeler means are associated with the guide means and are able to detect when the cleaning element, translating axially, reaches or approaches the upper or lower end of said guide means. When this happens, the feeler means are able to condition the drive of the motor means in order to return the cleaning element, and hence the scraper element, to the initial position, therefore keeping it substantially always at the same height.
the cleaning element consists of a first substantially annular element, functioning as a base, provided with a central hole inside which the tool is arranged.
the first element is free to translate axially along the guide means but is blocked rotationally by the guide means themselves.
a second element substantially annular and also axially holed, is associated to the first element by means of a rotation member such as an annular bearing or similar, and acts as a support for the scraper element.
the second element is not only movable axially together with the first element, but is also free to rotate around the longitudinal axis of the tool, and with respect to the first element, due to the presence of said rotation member.
the scraper element itself consists, in a preferential embodiment, of a roller element supported, by means of rotation means such as for example bearings or brasses, by an arm facing radially towards the axis of the tool and sized so that it can locate the roller element between two adjacent spirals of the screw.
the radial arm is mounted on the second element by means of a bolt-type joint, which allows a rapid and easy replacement according to the size and conformation of the screw; it also allows a rapid dismantling of the equipment and easy maintenance operations.
Motor means are mounted on the first element and are connected to the rotation member to make the second element rotate, together with the scraper element supported thereby, around the axis of the tool, normally following the direction of rotation thereof.
the cleaning device according to the invention functions as follows.
the second element is made to rotate by the motor means in substantially normal working conditions, keeping the scraper element in contact with the profile of the screw and facilitating the rotation thereof. In this way the scraper element remains in a substantially constant vertical position.
the roller in turn rotates on the axis of the supporting arm, rolling on the plane of the spirals of the screw, in order to perform its function of removing the material, together with the relative supporting arm.
the whole cleaning element not only rotates normally as driven by the motor means, but is also subjected to a translation force which displaces it along the guide means.
the sensors detect this condition and activate the motor means to modify the working conditions, following, in one direction or the other, the translatory movement of the tool and hence returning the cleaning element to the initial operating position.
the speed of rotation of the motor will be increased, or the direction of rotation will be inverted, so that the roller element, rolling on the plane of the spirals of the screw, returns to the initial position wherein the motor returns to its condition of normal rotation.
Another advantage of the present invention is that the material scraped from the screw is discharged at a substantially constant height, which allows to provide a member to convey the scraped material, so as to prevent the latter from falling back in proximity of the excavation zone.
a device 10 to clean screw-type tools such as drills 11 or similar, is applied to a conventional-type machine, not shown in greater detail in the drawings, for example of the type able to drill ground or lay pipes.
the cleaning device 10 comprises a cleaning element 40 consisting of a first, axially holed element 12, able to function substantially as a base, and a second element 20, consisting of an axially holed box-like structure 21 able to function as a support for a scraper element, indicated in its entirety by the reference number 25.
the cleaning element 40 is mounted on guide elements, consisting in this case of four column elements 15 arranged at the corners of said first element 12.
the column elements 15 are solid with a support, consisting in this case of a plate 24 attached, for example, to the drilling machine.
the first element 12 consists in this case of a pair of plates 12a, 12b arranged parallel to each other and having an axial hole 13 for the passage of the screw of the drill 11; peripherally said plates 12a, 12b have holes 14 for insertion on the guide column elements 15.
the first 12 and the second element 20 are connected together by means of a rotation member, consisting in this case of an annular bearing, of a conventional type and therefore not shown in the drawings, attached to an annular sheet 23 of the second element 20.
a rotation member consisting in this case of an annular bearing, of a conventional type and therefore not shown in the drawings, attached to an annular sheet 23 of the second element 20.
a motor 30 is mounted by means of a positioning hole 31 on the first element 12 and is able to make a pinion (not visible in the drawings) selectively rotate which engages on the outer circumference of the annular bearing, in order to make the second element 20 rotate with respect to the axis of rotation X of the drill 11 and the first element 12 itself.
the box-like structure 21 which constitutes the second element 20 has an axial hole 22 for the passage of the screw of the drill 11 and, at the upper part, an edge, flared towards the outside, which has the function of centering the drill 11.
the scraper element 25 substantially consists of a supporting arm 26, mounted below the second element 20 and facing radially towards the axis X of the drill 11; the arm 26 is able to support, on bearings or brasses 28, a roller 27 which is inserted between two adjacent spirals 11a of the screw and rests and rolls on the plane of said spirals 11a.
the whole cleaning element 40 is free to slide axially along the guide elements 15 when it is subjected to a force of linear translation caused by a translatory movement of the drill 11.
guide bushings 16 at the corners of the plates 12a, 12b there are guide bushings 16 able to maintain the plates 12a, 12b united and also to allow the linear sliding of the first element 12 along the guide columns 15.
end-of-travel means Near the ends, upper and lower, of the guide columns 15 there are end-of-travel means, respectively upper 18 and lower 19.
the end-of-travel means act on the motor means 30 to make them increase their speed, or invert the direction of rotation, in order to keep the cleaning element 40 always substantially at the same vertical height for any combination of translational and rotational speed of the drill 11.
This vertical height can be related to a fixed position with respect an external point of reference, which can be itself fixed or movable, of the machine where the drill 11 is mounted; for example, the point of reference can be a precise position of discharging of the material removed form the spirals of the drill 11, or can be a zone which is easily visible and controllable by an operator of the machine.
an external point of reference which can be itself fixed or movable, of the machine where the drill 11 is mounted; for example, the point of reference can be a precise position of discharging of the material removed form the spirals of the drill 11, or can be a zone which is easily visible and controllable by an operator of the machine.
the device 10 as described heretofore functions as follows.
the motor 30 makes the second element 20 rotate, by driving the annular bearing, and hence the scraper element 25 mounted on the second element 20, with a speed corresponding to a substantially stationary condition and with a direction of rotation which follows that of the drill 11.
the end-of-travel elements 19 command the direction of rotation of the motor 30 to be inverted, so that the scraper element 25, by the roller 27 rolling on the plane of the spirals 11a, returns to its initial position.
the cleaning element 40 if stressed by a component of vertical thrust due to the movement of the screw of the drill 11, can move only for a short travel defined by the desired distance between the two end-of-travel elements 18, 19; once these limit positions have been reached, it is automatically, and substantially instantaneously, returned to its nominal working position.
elastic means are provided, not shown in the drawings, able to keep the first element 12 and the second element 20 normally in a rest position substantially central with respect to the travel defined between the two end-of-travel elements 18 and 19.
