Description

Technical Field

[0001] This utility model belongs to the field of coal mine production technology, and more specifically, it relates to a belt cleaner. Background Technology

[0002] In the field of coal mining and transportation, belt conveyors are core equipment for the continuous transport of bulk materials, and their operational stability and transportation efficiency directly affect the overall benefits of coal mine production. During coal transportation, coal is transferred and transported via belt conveyors after crushing and screening. However, materials such as coal gangue and coal powder mixed in with the coal are prone to leave residues on the surface of the belt, especially the problem of coal gangue adhesion on the working face (upper surface) of the belt, which has long plagued the industry's production.

[0003] Currently, traditional belt conveyor cleaning solutions using soft cleaners struggle to handle the adhesion of hard residues such as coal and gangue. While hard cleaners can effectively remove coal and gangue, they easily wear down belt buckles, affecting the normal operation of the belt conveyor. Furthermore, the removed coal and gangue fall directly from beneath the belt under gravity, posing a significant risk of injury to personnel below, as the area beneath the belt conveyor is often used for inspections or equipment operation. Utility Model Content

[0004] The purpose of this utility model is to provide a belt cleaner to solve the technical problems in the prior art where belt buckles are easily damaged during the cleaning process and coal and gangue fall, posing a safety hazard.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a belt sweeper, comprising:

[0006] A storage shell is used to be fixedly installed below the belt conveyor; the upper end of the storage shell is provided with an opening communicating with the interior, and the lower end is provided with a detachable sealing plate.

[0007] There are two mounting brackets, arranged in parallel and spaced apart inside the storage shell; each mounting bracket is equipped with a connecting shaft and a torsion spring. The connecting shaft is rotatably connected to the mounting bracket, and the torsion spring is installed at the end of the connecting shaft, with both ends connected to the connecting shaft and the mounting bracket respectively.

[0008] Two cleaning blocks are fixedly installed on the two connecting shafts respectively. Multiple cleaning blocks in the same group are arranged at intervals along the length of the connecting shaft. Each cleaning block has a pointed structure, and the pointed structure passes through the opening and contacts the belt. Multiple cleaning blocks on the two connecting shafts are arranged alternately, and the width of each cleaning block is greater than or equal to the distance between two adjacent cleaning blocks.

[0009] In one possible implementation, the mounting bracket includes a base plate and two vertical plates respectively mounted on both sides of the base plate. The vertical plates are provided with connecting holes, and the connecting shaft is rotatably connected to the two connecting holes. The end of the connecting shaft is provided with a limiting flange, and the torsion spring is installed between the limiting flange and the corresponding vertical plate, and both ends are connected to the limiting flange and the vertical plate.

[0010] In one possible implementation, the connecting shaft is provided with a long strip block arranged along the length direction, and mounting holes are provided on both sides of the long strip block; the lower end of the cleaning block is provided with a mounting groove that mates with the long strip block, and both sides are provided with through holes communicating with the mounting groove and fasteners for fixing the cleaning block and the long strip block.

[0011] In one possible implementation, the cleaning block is arranged at an angle, with its upper end extending in the opposite direction to the direction of the lower belt movement; the upper surface of the cleaning block is an inclined surface, and the tip structure is located on the upper side of the inclined surface.

[0012] In one possible implementation, the cleaning block has a thickened portion on one side, which is located on the same side as the tip structure and below the tip structure.

[0013] In one possible implementation, the storage shell includes four side plates arranged in a rectangular shape and connected end to end, and two extension plates. The sealing plate is located at the lower end of the four side plates and is detachably connected to the side plates. The two extension plates are located at the upper end of the two parallel and spaced-apart side plates, and the two extension plates are respectively used to be fixedly connected to both sides of the frame of the belt conveyor.

[0014] In one possible implementation, a pivot is provided at the lower end of one of the side plates, a rotating hole is provided at one end of the sealing plate to be rotatably connected to the pivot, and a locking member is provided on the side plate corresponding to the other end of the sealing plate for connecting with the sealing plate.

[0015] In one possible implementation, vertically arranged elongated holes are provided on the corresponding side walls of the storage shell; the lower end face of the mounting bracket is provided with downwardly extending mounting plates on both sides, and the two mounting plates are respectively connected to the corresponding two inner walls of the storage shell; the mounting plates are provided with studs passing through the corresponding elongated holes and nuts threaded onto the studs.

[0016] In one possible implementation, an operating lever for gripping is provided between the two mounting plates.

[0017] In one possible implementation, the stud includes a square segment and a threaded segment arranged sequentially, the square segment being slidably connected to the elongated hole, the threaded segment being located outside the elongated hole, and the nut being mounted on the threaded segment.

[0018] The beneficial effects of the belt cleaner provided by this utility model are as follows: Compared with the prior art, when the belt is running, the belt drives the surface coal and gangue to contact the tip of the cleaning block. The tip structure effectively peels off the adhered coal and gangue. The double-set staggered cleaning blocks ensure that residual materials in the middle or edge of the belt can be thoroughly removed. The connecting shaft maintains the fit between the cleaning block and the belt under the action of the torsion spring. When encountering protruding structures such as belt buckles, the torsion spring undergoes elastic deformation, causing the connecting shaft to rotate slightly, so that the cleaning block temporarily avoids the belt buckle, significantly reducing the damage to the belt buckle caused by rigid friction and solving the problem of belt buckle wear caused by traditional hard cleaners. The removed coal and gangue fall into the shell through the opening of the storage shell under the action of gravity, avoiding direct fall to the working area below and eliminating the safety hazard of coal and gangue falling and injuring people.

[0034] Please see Figures 1 to 8 The belt cleaner provided by this utility model will now be described. A belt cleaner includes a storage shell 10, mounting frames 20, and a cleaning block assembly 30. The storage shell 10 is used for fixed installation below a belt conveyor 50. The upper end of the storage shell 10 has an opening 11 communicating with the interior, and the lower end has a detachably connected sealing plate 12. There are two mounting frames 20, arranged parallel and spaced apart within the storage shell 10. Each mounting frame 20 is provided with a connecting shaft 21 and a torsion spring 22. The connecting shaft 21 is rotatably connected to the mounting frame 20, and the torsion spring 22 is mounted on the connecting shaft 21. The end of the cleaning block group 30 is connected to the connecting shaft 21 and the mounting bracket 20 at both ends respectively; there are two cleaning block groups 30, which are fixedly installed on the two connecting shafts 21 respectively; multiple cleaning blocks 31 in the same group are arranged at intervals along the length direction of the connecting shaft 21, and each cleaning block 31 has a pointed structure 32, which passes through the opening 11 and contacts the belt 51; multiple cleaning blocks 31 on the two connecting shafts 21 are arranged alternately, and the width of the cleaning block 31 is greater than or equal to the distance between two adjacent cleaning blocks 31.

[0035] Compared with the prior art, the belt cleaner provided by this utility model consists of a storage shell 10, a mounting frame 20, and a cleaning block assembly 30. The storage shell 10 serves as the basic load-bearing component and is fixedly installed below the belt conveyor 50. The upper opening 11 provides a working channel for the cleaning blocks 31, while the detachable sealing plate 12 at the lower end facilitates the collection of coal and gangue. Two parallel and spaced mounting frames 20 provide support for the cleaning execution mechanism. The connecting shaft 21 rotatably connected to the mounting frames 20, together with the end torsion spring 22, forms an elastic pressure structure. The two ends of the torsion spring 22 are respectively connected to the connecting shaft 21 and the mounting frame 20, which ensures that the cleaning blocks 31 and the surface of the belt 51 maintain stable contact pressure, and can also buffer the impact force during the cleaning process through its own deformation. The cleaning block assembly 30 adopts a double-set staggered design. Its tip structure 32 passes through the opening 11 of the storage shell 10 and contacts the surface of the belt 51. The width of the cleaning blocks 31 is greater than the adjacent spacing, and the staggered arrangement achieves no dead angle coverage of the surface of the belt 51.

[0036] During operation, the belt 51 drives the surface coal and gangue to contact the tip of the cleaning block 31. The tip structure 32 effectively peels off the adhered coal and gangue. The double-set staggered cleaning blocks 31 ensure that residual material in the middle or at the edge of the belt 51 can be thoroughly removed. Under the action of the torsion spring 22, the connecting shaft 21 always maintains the fit between the cleaning block 31 and the belt 51. When encountering protruding structures such as belt buckles, the torsion spring 22 undergoes elastic deformation, causing the connecting shaft 21 to rotate slightly, so that the cleaning block 31 temporarily avoids the belt buckles, significantly reducing the damage to the belt buckles caused by rigid friction and solving the problem of wear on belt buckles in traditional hard cleaners. The removed coal and gangue falls into the storage shell 10 through the opening 11 under the action of gravity, avoiding direct fall to the working area below and eliminating the safety hazard of falling coal and gangue injuring people.

[0037] During daily operation, the swept coal gangue is naturally collected in the storage shell 10. The accumulated material in the shell can be cleaned periodically by disassembling the lower end sealing plate 12, making maintenance and operation simple.

[0038] Please see Figures 1 to 5 As a specific embodiment of the belt sweeper provided by this utility model, the mounting frame 20 includes a base plate 23 and two vertical plates 24 respectively mounted on both sides of the base plate 23. The vertical plates 24 are provided with connecting holes, and the connecting shaft 21 is rotatably connected to the two connecting holes. The end of the connecting shaft 21 is provided with a limiting flange 25, and a torsion spring 22 is installed between the limiting flange 25 and the corresponding vertical plate 24, with both ends connected to the limiting flange 25 and the vertical plate 24. This optimizes the core support and transmission structure of the belt sweeper. The mounting frame 20 adopts a frame design of base plate 23 plus two vertical plates 24 on both sides. The base plate 23 provides stable support, and the connecting holes on the two vertical plates 24 provide precise rotation fulcrums for the connecting shaft 21, ensuring that the connecting shaft 21 rotates flexibly and is reliably positioned during sweeping operations. The limiting flange 25 at the end of the connecting shaft 21 plays an axial positioning role, effectively preventing axial displacement or detachment of the connecting shaft 21 during rotation, ensuring the stability of equipment operation. The torsion spring 22 is installed between the limiting flange 25 and the vertical plate 24. The structural design, with the limiting flange 25 and the vertical plate 24 connected at both ends, allows the elastic force of the torsion spring 22 to act directly on the connecting shaft 21. The contact pressure of the cleaning block 31 on the belt 51 is precisely adjusted by the deformation of the torsion spring 22. When a protrusion appears on the surface of the belt 51 or the belt buckle passes by, the torsion spring 22 can drive the connecting shaft 21 to make a fine adjustment through elastic contraction, avoiding rigid collision.

[0039] Please see Figure 2 , Figure 4 and Figure 5As a specific embodiment of the belt cleaner provided by this utility model, the connecting shaft 21 is provided with a long strip block 26 arranged along the length direction, and mounting holes 27 are opened on both sides of the long strip block 26; the lower end of the cleaning block 31 is provided with a mounting groove 33 that mates with the long strip block 26, and both sides are provided with through holes 34 communicating with the mounting groove 33 and fasteners 35 for fixing the cleaning block 31 and the long strip block 26. The long strip block 26 arranged along the length direction on the connecting shaft 21 serves as the connecting base, and the mounting holes 27 on both sides provide precise positioning for fixing the cleaning block 31; the mounting groove 33 at the lower end of the cleaning block 31 and the long strip block 26 form a fitting and fitting structure. During installation, the cleaning block 31 is inserted into the long strip block 26 through the mounting groove 33, so that the through holes 34 on both sides are aligned with the mounting holes 27 of the long strip block 26, and then fasteners 35 such as bolts and nuts 42 are used to fix it, so as to achieve a stable connection between the cleaning block 31 and the connecting shaft 21. Through this structure, the interlocking mounting groove 33 and the fastener 35 ensure that the cleaning block 31 is not easily loosened or shifted during high-speed cleaning operations, ensuring the stability of the contact between the tip structure 32 and the belt 51 and improving the cleaning effect; the matching design of the long strip 26 and the mounting groove 33 ensures the positioning accuracy of the cleaning block 31 along the connecting shaft 21, ensuring that the spacing of the cleaning blocks 31 in the same group is uniform, and the double-group staggered arrangement achieves cleaning without dead angles.

[0040] Please see Figure 4 and Figure 5 As a specific embodiment of the belt cleaner provided by this utility model, the cleaning block 31 is arranged in an inclined shape, with its upper end extending in the opposite direction to the movement direction of the lower belt 51; the upper surface of the cleaning block 31 is an inclined surface 36, and the tip structure 32 is located on one side of the upper end of the inclined surface 36. The cleaning block 31 is arranged in an inclined shape, with its upper end extending in the opposite direction to the movement of the belt 51, forming an operating angle opposite to the running trajectory of the belt 51; the upper surface is designed as an inclined surface 36, and the tip structure 32 is located on one side of the upper end of the inclined surface 36, so that the tip forms an acute angle contact with the surface of the belt 51. During operation, the belt 51 moves forward, and the inclined cleaning block 31, with its reverse extension posture, allows the tip structure 32 to contact the coal and gangue on the surface of the belt 51 before the main body of the cleaning block 31. Utilizing the acute angle characteristic of the tip, it accurately inserts into the adhesion gap between the coal and gangue and the belt 51, and efficiently peels off the residual material through shearing force. The inclined surface 36 serves as a guide, directing the stripped coal and gangue downwards along the inclined surface 36 into the storage shell 10, thus preventing the coal and gangue from accumulating on the surface of the cleaning block 31.

[0041] Please see Figure 5As a specific embodiment of the belt cleaner provided by this utility model, a thickened portion 37 is provided on one side of the cleaning block 31. The thickened portion 37 is disposed on the same side as the tip structure 32 and is located below the tip structure 32. The thickened portion 37 of the cleaning block 31, being on the same side as and below the tip structure 32, forms a targeted reinforcement structure. By increasing the material thickness below the tip structure 32, the thickened portion 37 enhances the structural strength and rigidity of the critical stress area of ​​the cleaning block 31. When the tip structure 32 contacts and peels off the coal and gangue on the surface of the belt 51, the thickened portion 37 can effectively disperse the impact and friction forces borne by the tip, preventing breakage or excessive wear below the tip due to long-term high-intensity cleaning.

[0042] Please see Figures 1 to 4 As a specific embodiment of the belt cleaner provided by this utility model, the storage shell 10 includes four rectangular side plates 13 connected end to end and arranged in a rectangular shape, and two extension plates 14. A sealing plate 12 is located at the lower end of the four side plates 13 and is detachably connected to the side plates 13. The two extension plates 14 are located at the upper end of two parallel and spaced-apart side plates 13, and are respectively used to fix them to both sides of the frame of the belt conveyor 50. The storage shell 10 is composed of four rectangular side plates 13 connected end to end forming the main frame. The lower end is closed by the detachable sealing plate 12, and the upper ends are fixed to the frame of the belt conveyor 50 by extension plates 14 on both sides. The rectangular side plates 13 form a closed space, which can effectively collect and clean fallen coal and gangue, preventing materials from scattering to the working area below. The detachable sealing plate 12 facilitates regular cleaning of accumulated material inside the shell, reducing maintenance difficulty. The fixed connection method between the extension plates 14 and both sides of the frame ensures that the storage shell 10 is installed firmly and stably. The extension plate 14 is provided with multiple through holes for fixing the extension plate 14 to the frame using bolts or the like.

[0043] Please see Figure 1 and Figure 4 As a specific embodiment of the belt cleaner provided by this utility model, a rotating shaft 15 is provided at the lower end of one side plate 13, and a rotating hole is provided at one end of the sealing plate 12 for rotatably connecting with the rotating shaft 15. A locking member is provided on the side plate 13 corresponding to the other end of the sealing plate 12 for connecting with the sealing plate 12. A rotating shaft 15 is provided at the lower end of one side plate 13 of the storage shell 10, and one end of the sealing plate 12 is rotatably connected to the rotating shaft 15 through the rotating hole. The other end is fixed with a locking member corresponding to the side plate 13. This structure allows the sealing plate 12 to rotate flexibly around the rotating shaft 15. It does not need to be completely disassembled when opening, and it is firmly fixed by the locking member when closing. The rotating connection design greatly simplifies the cleaning operation of the material accumulation inside the shell. The staff does not need to frequently disassemble and assemble the sealing plate 12, which improves the maintenance efficiency. The locking member ensures that the sealing plate 12 fits tightly against the side plate 13 when closed, preventing coal and gangue from leaking out from the gaps and avoiding safety hazards to the area below. Locking devices can include latch locks, bolt and nut 42 components, pin-type locking devices, magnetic locking devices, etc.

[0044] Please see Figure 1 , Figure 4 , Figure 6 and Figure 7 As a specific embodiment of the belt cleaner provided by this utility model, the storage shell 10 has vertically arranged elongated holes 16 on both corresponding side walls; the lower end face of the mounting frame 20 has downwardly extending mounting plates 40 on both sides, and the two mounting plates 40 are respectively connected to the corresponding inner walls of the storage shell 10; the mounting plates 40 are provided with studs 41 that pass through the corresponding elongated holes 16 and nuts 42 that are threaded onto the studs 41. The storage shell 10 has vertically arranged elongated holes 16 on both sides, and the mounting plates 40 on both sides of the lower end of the mounting frame 20 are connected to the inner walls of the storage shell 10. The studs 41 on the mounting plates 40 pass through the elongated holes 16 and are fixed by the nuts 42. This structure achieves height adjustment of the mounting frame 20 by vertical movement of the studs 41 in the elongated holes 16, and the position is fixed by tightening the nuts 42. The adjustment function can flexibly adjust the contact pressure between the cleaning block 31 and the belt 51 according to the wear degree of the belt 51 or the adhesion of coal and gangue, so as to ensure the cleaning effect while avoiding excessive pressure and damage to the belt 51.

[0045] Please see Figure 6 As a specific embodiment of the belt sweeper provided by this utility model, an operating rod 43 for gripping is provided between the two mounting plates 40. The operating rod 43 added between the two mounting plates 40 provides a convenient gripping structure for adjusting the mounting frame 20. The operating rod 43 is connected between the mounting plates 40 to form a stable force support point. When it is necessary to adjust the contact pressure between the sweeping block 31 and the belt 51, the operator can directly grip the operating rod 43 and move it up and down to drive the mounting frame 20 to adjust its position vertically along the elongated hole 16 of the storage shell 10, and complete the fixation with the stud 41 and nut 42.

[0046] Please see Figure 7 As a specific embodiment of the belt cleaner provided by this utility model, the stud 41 includes a square segment 44 and a threaded segment 45 arranged sequentially. The square segment 44 is slidably connected to the elongated hole 16, and the threaded segment 45 is located outside the elongated hole 16. A nut 42 is installed on the threaded segment 45. The stud 41 is adapted to the elongated hole 16 of the storage shell 10 through the segmented design of the square segment 44 and the threaded segment 45. The square segment 44 and the elongated hole 16 form a sliding fit, and the limiting effect of the square structure prevents the stud 41 from rotating during adjustment or fixing, ensuring the relative position stability of the mounting plate 40 and the storage shell 10. The threaded segment 45 extends out of the elongated hole 16, and the mounting bracket 20 is fixed and locked by tightening the nut 42. This design allows the stud 41 to slide smoothly along the elongated hole 16 when the height of the mounting bracket 20 is adjusted, avoiding adjustment deviation, and the connection is firm after the nut 42 is tightened.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
