A fixing sleeve 10 is fixed to the outer wall of the mounting frame 4, and a rotating rod 11 is penetrated through the side wall of the mounting frame 4, and the rotating rod 11 is rotatably connected to the penetration of the mounting frame 4, and the end point of the rotating rod 11 is fixedly connected to the side wall of the rotating column 6, and a spring 12 is fixed to the outer wall of the rotating rod 11, and the side of the spring 12 away from the rotating rod 11 is fixed to the inner wall of the fixing sleeve 10, and a disc 16 is fixed to the outer wall of the rotating rod 11, and an extrusion block 18 is fixed to the outer wall of the disc 16 The outer wall of the disk 16 is provided with a card slot 17, an L-shaped slider 13 is slidably installed on the side wall of the installation frame 4, a limit block 14 is slidably installed on the inner side of the L-shaped slider 13, a connecting spring 15 is fixed to the side wall of the limit block 14, a side of the connecting spring 15 away from the limit block 14 is fixed to the inner side of the L-shaped slider 13, the outer wall of the limit block 14 is fitted with the inner wall of the card slot 17, an L-shaped transmission block 19 is slidably installed on the side wall of the installation frame 4, a hinged rod 20 is hinged to the side wall of the L-shaped slider 13 at one end of the hinged rod 20 away from the L-shaped transmission block 19, and the L-shaped transmission block A return spring 21 is fixed to the top of 19, and the top of the return spring 21 is fixed to the inner side of the mounting frame 4. A rotating rod 23 is passed through the side wall of the L-shaped transmission block 19, and a rotating disk 25 is fixed to one end of the rotating rod 23, and a collecting box 24 is fixed to the other end of the rotating rod 23. An L-shaped transmission rod 22 is passed through the L-shaped transmission block 19, and the top of the L-shaped transmission rod 22 is fixed to the inner side of the outer wall of the mounting frame 4. A sleeve rod 26 is slidably installed on the inner side of the L-shaped transmission rod 22, and a movable rod 27 is hinged on the top of the sleeve rod 26, and one end of the movable rod 27 away from the L-shaped transmission rod 22 is hinged to the outer wall of the rotating disk 25.

[0034] When the limit block 14 is in the slot 17, the mainspring 12 is in a state of contraction and deformation, so that the mainspring 12 applies a reverse force to the rotating rod 11. When the limit block 14 is removed from the slot 17, the limit on the disc 16 can be released. Since the mainspring 12 is in a contracted state, the mainspring 12 drives the rotating rod 11 and the rotating column 6 to reverse, thereby achieving the effect of switching the brush roller 9.

[0035] The angle between the top of the extrusion block 18 and the top of the limit block 14 is 180°. When the disc 16 drives the extrusion block 18 to rotate to the top of the limit block 14, the rotating rod 11 will rotate 180°, thereby rotating the rotating column 6 180°, so that the switched brush roller 9 will rotate to the position of cleaning the belt.

[0036] By arranging a connecting spring 15 on the inner side of the L-shaped slider 13, when the L-shaped slider 13 approaches the disk 16, the limit block 14 will be pressed against the outer wall of the disk 16, so that the connecting spring 15 is compressed. By rotating the disk 16 forward, when the disk 16 rotates until the slot 17 is aligned with the limit block 14, the limit block 14 can be extended into the slot 17 through the cooperation of the connecting spring 15.

[0037] A belt conveyor belt cleaning method, using the above-mentioned belt conveyor belt cleaning device, comprises the following steps:

[0038] Step 1: When the belt of the conveyor 1 needs to be cleaned, the device is moved to the end point of the conveyor 1, and then the position of the device is adjusted so that the outer wall of the brush roller 9 fits with the end of the conveyor 1 belt, and the top of the scraper 5 fits with the outer wall of the conveyor 1 belt;

[0039] Step 2: After the brush roller 9 is attached to the belt, the conveyor 1 is started, so that the belt of the conveyor 1 rotates from left to right, and the drive motor 8 is started, so that the drive shaft of the drive motor 8 drives the brush roller 9 to reverse, and the conveyor 1 belt is cleaned by the brush roller 9;

[0040] Step three: When the brush roller 9 finishes cleaning the impurities on the belt, the belt cleaned by the brush roller 9 will rotate to the scraper 5, and the scraper 5 will clean the impurities adhering to the belt, so that the cleaned impurities will fall into the collection box 3 for collection.

[0041] When the present embodiment is working: when it is necessary to clean the belt of the conveyor 1, the device is moved to the designated position, the brush of the brush roller 9 is brought into contact with the belt at the end of the conveyor 1, and the top of the scraper 5 is brought into contact with the outer wall of the belt, and the conveyor 1 and the drive motor 8 are started to clean the belt, and after the brush roller 9 is cleaned, the belt is rotated to the scraper 5, and the scraper 5 can scrape off the impurities adhering to the belt, and when the brush roller 9 is cleaned to a certain extent, the amount of impurities falling into the collection box 24 will increase, so that the collection box 24 will drive the L-shaped transmission block 19 to move downward, and when the L-shaped transmission block 19 moves downward, the L-shaped transmission block 19 will be pressed against the hinged rod 2 0 is pulled to rotate the hinged rod 20 at the hinge, so that the hinged rod 20 pulls the L-shaped slider 13 away from the disc 16, driving the limit block 14 to move out of the card slot 17, and releasing the limit on the disc 16. Because the clockwork spring 12 is in a contracted state, the clockwork spring 12 drives the rotating rod 11 to reverse, so that the rotating column 6 and the fixed frame 7 are reversed. When the disc 16 drives the extrusion block 18 to rotate to the top of the limit block 14, the limit block 14 limits the position of the extrusion block 18, thereby stopping the rotation of the disc 16, rotating the unused brush roller 9 to the position of the belt cleaning, and rotating the used brush roller 9 to the position where the cleaning operation is not performed, thereby ensuring that the cleaning operation is completed without stopping the machine. The switching of the brush roller 9 facilitates the cleaning operation and improves the work efficiency. When the limit block 14 is moved out of the slot 17, the sleeve rod 26 will move to the bottom of the inner wall of the L-shaped transmission rod 22. Then, when the L-shaped transmission block 19 continues to move downward, the sleeve rod 26 will squeeze the movable rod 27, so that the movable rod 27 squeezes the rotating disk 25 to reverse, so that the rotating disk 25 drives the rotating rod 23 to reverse, and the collecting box 24 is reversed, so that the impurities collected in the collecting box 24 are discharged, and the next collection operation is carried out. When the impurities in the collecting box 24 are discharged, the reset spring 21 will be deformed and stretched because the L-shaped transmission block 19 moves downward, so that the collecting box 24 has no weight, and the reset spring 21 is used to release the impurities in the collecting box 24. The spring 21 drives the L-shaped transmission block 19 to move upward. Since the elastic coefficient of the reset spring 21 is greater than the elastic coefficient of the connecting spring 15, when the L-shaped transmission block 19 moves upward, the L-shaped transmission block 19 will squeeze the hinged rod 20 at the hinge, so that the L-shaped slider 13 drives the limit block 14 to reset, and the limit block 14 will be against the outer wall of the disk 16, thereby compressing the connecting spring 15. When resetting is required, the disk 16 is rotated forward, so that the rotating rod 11 drives the mainspring 12 to shrink and deform. When the slot 17 of the disk 16 rotates to align with the limit block 14, since the connecting spring 15 is in a compressed state, the limit block 14 will extend into the slot 17, thereby fixing the disk 16 and performing the next switching operation.

[0043] When the arc surface of the arc block 286 rotates on the arc surfaces of the multiple groups of semicircular blocks 283, the connection plate 285 moves back and forth left and right through the cooperation of the transmission spring 287;

[0044] A plurality of sets of striking rods 288 are inserted into the brush of the brush roller 9. When the striking rods 288 move back and forth in the brush of the brush roller 9, impurities attached to the brush can be knocked off, thereby realizing self-cleaning of the brush roller 9, facilitating subsequent cleaning operations of the brush roller 9 on the belt, and reducing the labor of the staff.

[0045] The toggle assembly includes an L-shaped extrusion rod 291, a stopper 292, a long plate 293, an inclined groove 294, a hinge seat 295, a toggle block 296 and a fixed plate 297. The L-shaped extrusion rod 291 passes through the connecting plate 285, and the L-shaped extrusion rod 291 fits with the connecting plate 285 at the penetration point. The end of the L-shaped extrusion rod 291 is fixed with a stopper 292. The side wall of the stopper 292 is rotatably connected to the side wall of the connecting plate 285.

The end of the slide bar 298 away from the fixed plate 297 is fixed to the side wall of the long plate 293.

[0046] When the L-shaped extrusion rod 291 moves in the inclined groove 294, the long plate 293 will move under the extrusion force, so that the long plate 293 can drive the slide rod 298 to move on the inner wall of the slide groove of the fixed plate 297, thereby driving the toggle block 296 to toggle at the angle between the belt and the scraper 5, and to toggle the impurities attached to the angle off, to prevent the accumulation of impurities which will increase the friction between the belt and the scraper 5, resulting in increased wear of both and shortening the service life.

[0047] When this embodiment is working: when the rotating column 6 drives the fixed frame 7 to reverse, the fixed frame 7 will drive the striking assembly to reverse, and when the arc block 286 rotates to contact the semicircular block 283, the arc block 286 will be subjected to extrusion force, so that the arc block 286 drives the connecting plate 285 to move toward the fixed frame 7, compressing the transmission spring 287, so that the connecting plate 285 drives the connecting rod 284 and the striking rod 288 to move in the brush of the brush roller 9, and when the arc block 286 rotates between the two groups of semicircular blocks 283, because the transmission spring 287 is in a compressed state, the connecting plate 285 drives the connecting rod 284 and the striking rod 288 to reset, and then when the connecting plate 285 rotates, the striking rod 288 will move back and forth in the brush of the brush roller 9, knocking off the impurities attached to the brush roller 9.

[0048] When the connecting plate 285 moves toward the fixed frame 7, the connecting plate 285 pushes the stopper 292 to move toward the fixed frame 7, so that the stopper 292 drives the L-shaped extrusion rod 291 to move in the inclined groove 294 of the long plate 293, so that the L-shaped extrusion rod 291 squeezes the long plate 293 to move toward the scraper 5, so that the long plate 293 drives the slide bar 298 to move toward the scraper 5, and the slide bar 298 moves in the slide groove of the side wall of the fixed plate 297, so that the slide bar 298 squeezes the fixed plate 297 to move, so that the fixed plate 297 drives The toggle block 296 rotates at the hinge to move the toggle block 296 out of the scraper 5, so that the toggle block 296 can push and drop the impurities attached to the angle between the belt and the scraper 5, and when the connecting plate 285 drives the stopper 292 away from the fixed frame 7, the L-shaped extrusion rod 291 will move away from the fixed frame 7 in the inclined groove 294, and the long plate 293 will move away from the scraper 5, so that the long plate 293 drives the sliding rod 298 to reset, and the fixed plate 297 is squeezed and rotated to be straightened, so that the toggle block 296 returns to its original position for the next cleaning operation.
