DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] like Figures 1 to 6 As shown, a rotary belt cleaning device includes a conveyor belt 1 and a receiving hopper 2. The receiving hopper 2 is arranged at the tail end of the conveyor belt 1, and also includes a cleaning mechanism and an adjusting mechanism. The cleaning mechanism is connected to the adjusting mechanism. The cleaning mechanism is located above the receiving hopper 2 and below the conveyor belt 1. In this embodiment, the cleaning mechanism is used to clean the material adhered to the working surface of the conveyor belt 1. The height and horizontal position of the cleaning mechanism can be adjusted by the adjusting mechanism to ensure that the cleaning mechanism can always clean the material adhered to the conveyor belt 1 and facilitate the removal of the cleaning mechanism from under the conveyor belt 1. By installing the receiving hopper 2 at the tail end of the conveyor belt 1, it is convenient to collect the material cleaned by the cleaning mechanism, so as to prevent the material from falling off the belt corridor below the conveyor belt 1 and falling onto the ground.

[0030] The adjustment mechanism includes a U-shaped seat 3 and a transverse movement assembly. The U-shaped seat 3 is provided on both sides of the receiving hopper 2. The transverse movement assembly is provided on the outside of each U-shaped seat 3. The transverse movement assembly includes a transverse movement seat 7 and a transverse movement slider 10. The transverse movement seat 7 is fixedly provided on the outside of the U-shaped seat 3, and the transverse movement slider 10 is slidably provided on the transverse movement seat 7. In this embodiment, the height of the transverse movement assembly can be adjusted by moving the U-shaped seat 3 to achieve the purpose of adjusting the height of the cleaning mechanism; the transverse movement assembly is used to adjust the horizontal position of the cleaning mechanism.

[0031] The cleaning mechanism includes a brush assembly and a drive assembly for rotating the brush assembly, wherein the drive assembly is connected to the transverse movement assembly. In this embodiment, the brush assembly contacts the lower portion of the conveyor belt 1 and is driven by the drive assembly to rotate the brush assembly below the conveyor belt 1, thereby achieving the effect of the brush assembly cleaning materials adhered to the working surface of the conveyor belt 1. When the conveyor belt 1 rotates clockwise, that is, the movement direction of the lower portion of the conveyor belt 1 is to the left, the drive assembly drives the brush assembly to rotate clockwise.

[0032] A plurality of adjustment holes 4 are arranged at intervals on both sides of the U-shaped seat 3. A fixing bolt 5 matching the adjustment holes 4 is provided on the upper portion of the receiving hopper 2. The U-shaped seat 3 is connected to the receiving hopper 2 via the fixing bolts 5. In this embodiment, there are five adjustment holes 4 on each side of the U-shaped seat 3, and the adjustment holes 4 are threaded holes. There are two fixing bolts 5. By cooperating with the fixing bolts 5 and the adjustment holes 4, the height of the U-shaped seat 3 can be adjusted to achieve the effect of adjusting the height of the cleaning mechanism. When adjusting the height of the cleaning mechanism, the fixing bolts 5 fixing the U-shaped seat 3 are removed, and then the U-shaped seat 3 is moved upward. When the cleaning mechanism reaches the required height, the adjustment holes 4 of the U-shaped seat 3 are aligned with the threaded holes on the receiving hopper 2. The fixing bolts 5 are then passed through the adjustment holes 4 and the threaded holes on the receiving hopper 2 to fix the U-shaped seat 3. After the two U-shaped seats 3 are re-fixed, the operation of adjusting the height of the cleaning mechanism is completed.

[0033] Multiple guide rails 6 are spaced apart on either side of the receiving hopper 2. Guide rail grooves matching the guide rails 6 are defined within the inner side of the U-shaped seat 3, with the guide rails 6 positioned within the grooves. In this embodiment, there are two guide rails 6 on each side of the receiving hopper 2, and two guide rail grooves within the inner side of the U-shaped seat 3. The guide rails 6 correspond to the grooves, and when the U-shaped seat 3 is moved, it slides on the receiving hopper 2 and the guide rails 6. The cooperation between the guide rails 6 and the grooves acts as a limiting guide for the movement of the U-shaped seat 3.

[0034] A chute 8 is provided on the top of the transverse seat 7, and the transverse slider 10 is slidably arranged in the chute 8; a limiting arc groove 9 is symmetrically provided in the chute 8, and limiting arc blocks 11 are symmetrically provided on both sides of the lower part of the transverse slider 10. The limiting arc blocks 11 match the limiting arc groove 9 and are located in the limiting arc groove 9. In this embodiment, the chute 8 is used to allow the transverse slider 10 to slide on the transverse seat 7, so that the transverse sliders 10 of the two adjustment mechanisms can drive the cleaning mechanism to move out from under the conveyor belt 1, wherein when the transverse slider 10 slides in the chute 8, the limiting arc block 11 slides in the limiting arc groove 9. Through the cooperation of the limiting arc block 11 and the limiting arc groove 9, the movement of the transverse slider 10 is limited and guided.

[0035] Two sets of locking holes 12 are arranged on the top of the transverse seat 7. Locking plates 13 are fixedly installed on both sides of the transverse slider 10. The locking plates 13 are located on the top of the transverse seat 7. Locking bolts 14 are provided on the locking plates 13 to cooperate with the locking holes 12. In this embodiment, the locking holes 12 are threaded holes and match the locking bolts 14. When the horizontal position of the cleaning mechanism needs to be adjusted, the locking bolts 14 are removed from the locking plates 13 and the transverse seat 7 to release the restraint on the transverse slider 10. As the transverse slider 10 slides in the chute 8, the locking plates 13 slide on the top of the transverse seat 7.

[0036] A support block 15 is fixedly mounted on the top of the transverse slider 10, and a mounting plate 16 is mounted on the top of the support block 15. In this embodiment, the support block 16 serves to mount and support the mounting plate 16. The mounting plate 16 is bolted to the top of the support block 16, and the mounting plate 16 serves to mount the seated bearing 17 and the reduction motor 20.

[0037] The drive assembly includes a reduction motor 20 and two bearing blocks 17. The two bearing blocks 17 are respectively mounted on top of the two mounting plates 16, and the reduction motor 20 is mounted on top of one of the mounting plates 16. In this embodiment, the two bearing blocks 17 are bolted to the tops of the two mounting plates 16, and the mounting plates 16 support the reduction motor 20, which drives the brush assembly to rotate.

[0038] The brush assembly includes a brush shaft 18 and a brush 19. The ends of the brush shaft 18 are interference fit with the inner rings of the two seat bearings 17. One end of the brush shaft 18 passes through the seat bearings 17 and is connected to the output shaft of the reduction motor 20. In this embodiment, the two seat bearings 17 enable the reduction motor 20 to drive the brush shaft 18 to rotate.

[0039] The brushes 19 are evenly distributed on the brush shaft 18, and the brushes 19 are in contact with the conveyor belt 1. In this embodiment, the brush shaft 18 drives the brushes 19 to rotate during rotation, and the brushes 19 are used to clean the materials adhered to the working surface of the conveyor belt 1.

[0040] The working principle of the present utility model is as follows: when the conveyor belt 1 of the belt conveyor rotates clockwise to convey materials, when it is necessary to clean the materials adhered to the working surface of the conveyor belt 1, the reduction motor 20 is turned on, and the output shaft of the reduction motor 20 drives the brush shaft 19 to rotate clockwise, and the brush shaft 19 drives the brush 19 to rotate clockwise. During the operation of the conveyor belt 1, the brush 19 can clean the materials adhered to the working surface of the conveyor belt 1, and the cleaned materials fall into the receiving hopper 2.

[0041] When the brush 19 is severely worn and affects the effect of cleaning materials, it is necessary to adjust the height of the brush assembly, that is, remove the fixing bolts 5 that fix the U-shaped seat 3, release the limit on the two U-shaped seats 3, and then move the two U-shaped seats 3 upward at the same time. When the brush 19 of the brush assembly is in full contact with the conveyor belt 1 again, that is, when the brush assembly reaches the required height, stop moving the two U-shaped seats 3 upward, and then make the adjustment holes 4 of the two U-shaped seats 3 correspond to the threaded holes on the hopper 2 respectively, and then pass the fixing bolts 5 through the adjustment holes 4 on the two U-shaped seats 3 and the threaded holes on the hopper 2 to fix the U-shaped seat 3. After the two U-shaped seats 3 are re-fixed, the operation of adjusting the height of the brush assembly is completed.

[0042] When the brush assembly needs to be disassembled and replaced, the locking bolt 14 is removed from the locking plate 13 and the transverse seat 7, and the limits on the two transverse sliders 10 are released respectively. Then, the two transverse sliders 10 are moved to the right at the same time. The transverse slider 10 slides to the right in the slide groove 8, the locking plate 13 slides to the right on the top of the transverse seat 7, and the limiting arc block 11 slides to the right in the limiting arc groove 9. When the brush assembly is completely removed from under the conveyor belt 1, the brush assembly can be disassembled and replaced.

[0043] The embodiments described above are only preferred embodiments of the utility model and do not limit the scope of implementation of the utility model. Therefore, any equivalent changes or modifications made according to the technical solutions described in the patent scope of the utility model should be included in the scope of the patent application of the utility model.
