A screen shaft pulley 11 is sleeved on the right end of the screen shaft 7, and a V-belt 12 is sleeved on the screen shaft pulley 11. A cleaning shaft pulley 13 is sleeved on the right end of the rotating square shaft 18, and the cleaning shaft pulley 13 and the V-belt 12 cooperate with each other to form a power mechanism. When the screen shaft 7 rotates, the screen shaft 7 drives the screen The shaft pulley 11 rotates. Since the screen shaft pulley 11, the V-belt 12 and the cleaning shaft pulley 13 cooperate with each other to form a power mechanism, the rotating square shaft 18 rotates at this time, so that the cleaning teeth 16 on the rotating square shaft 18 clean the materials between the screen plates 8 on the screen shaft 7 in turn. In this way, when the screen shaft 7 rotates, the rotating square shaft 18 drives the cleaning teeth 16 to rotate, thereby cleaning the materials on the screen shaft 7. The two rows and four groups of cleaning teeth 16 clean the screen shaft in turn, thereby effectively reducing the contact and wear between the cleaning teeth 16 and the screen shaft 7, thereby effectively improving the service life of the cleaning teeth 16.

[0030] A plurality of groups of cleaning teeth 16 are evenly arranged on the rotating square shaft 18 inside the roller screen box 1, each group of cleaning teeth 16 has two cleaning teeth 16, and the cleaning teeth 16 are opposed to each other up and down. By increasing the number of cleaning teeth 16 on the screen shaft 7 to four rows, the cleaning efficiency of the device during operation is greatly improved.

[0031] A through hole is provided on the side away from each other of each group of cleaning teeth 16, and a fixing bolt 17 is installed inside the through hole of the rear cleaning teeth 16, and the insertion end of the fixing bolt 17 extends to the outside of the front cleaning teeth 16 through the square shaft through hole 19. Each group of cleaning teeth 16 is installed on the rotating square shaft 18 through the square shaft through hole 19 and the fixing bolt 17. Therefore, when a cleaning tooth 16 is seriously worn or damaged, it is only necessary to screw the fixing bolt 17 on the square shaft through hole 19 so that the square shaft through hole 19 no longer connects the worn cleaning tooth 16 to the rotating square shaft 18, and then replace the cleaning tooth 16 that needs to be replaced, which greatly reduces the maintenance and repair costs.

[0032] A first bevel gear 21 is sleeved on the right end of the rotating square shaft 18 inside the roller screen box 1, a sleeve 20 is fixedly installed on the right side of the inner wall of the roller screen box 1, a rotating shaft 23 is movably sleeved on the inner side of the sleeve 20, a second bevel gear 22 is fixedly installed on the top of the rotating shaft 23, and the second bevel gear 22 and the first bevel gear 21 are meshed with each other, a fixing frame 26 is fixedly installed on the right side of the inner wall of the roller screen box 1, a sliding frame 25 is slidably installed on the top of the fixing frame 26, a half gear 24 is provided inside the sliding frame 25, and the teeth on the half gear 24 cooperate with the teeth inside the sliding frame 25, the top of the half gear 24 is fixedly connected to the bottom end of the rotating shaft 23, and the left side of the sliding frame 25 is fixedly installed on the right side of the inner wall of the roller screen box 1. A plug plate 38 is fixedly installed on the side, and a connecting plate 27 is provided on the left side of the plug plate 38. A sponge plate 28 is fixedly installed on the top of the connecting plate 27. The first bevel gear 21 is driven to rotate by rotating the square shaft 18. The first bevel gear 21 is meshed with the second bevel gear 22, thereby driving the rotating shaft 23 to rotate, and the half gear 24 at the bottom end of the rotating shaft 23 is meshed with the sliding frame 25, so that the sliding frame 25 slides left and right on the fixed frame 26, so that the sponge plate 28 slides on the cleaning teeth 16, thereby cleaning the materials adhered to the fixed frame 26, thereby reducing the accumulation of materials on the cleaning teeth 16, thereby affecting the cleaning efficiency of the cleaning teeth 16 for the second bracket 8.

[0033] A slot 29 is provided on the right side of the connecting plate 27, and the left end of the plug plate 38 is inserted into the inside of the slot 29. A second cavity 32 is provided in the connecting plate 27 at the bottom of the inner wall of the slot 29, and the second cavity 32 is communicated with the slot 29. A first cavity 30 is provided at the bottom end of the plug plate 38, and a compression spring 31 is fixedly installed inside the first cavity 30. A limit plug block 39 is fixedly installed at the bottom end of the compression spring 31, and the bottom end of the limit plug block 39 extends to the inside of the second cavity 32. A slide groove 36 is provided in the connecting plate 27 at the top of the inner wall of the slot 29, and a slider 37 is slidably installed inside the slide groove 36. The bottom end of the slider 37 is connected to the plug plate 38. The top of the plug board 38 is fixedly connected. When installing, the slot 29 is aligned with the plug board 38 and inserted. When inserting, the right side of the connecting plate 27 squeezes the limiting plug block 39. At this time, the limiting plug block 39 is forced to move inward, thereby driving the compression spring 31 to compress and deform. When the plug board 38 is completely inserted into the inside of the slot 29, the elastic potential energy generated by the compression of the compression spring 31 is released, and the elastic force generated by the reset drives the limiting plug block 39 to be inserted into the inside of the second cavity 32. At this time, the limiting plug block 39 and the second cavity 32 limit each other, so that the plug board 38 is connected and limited with the connecting plate 27. At this time, the installation is completed. The installation is fast and convenient, which greatly improves the flexibility of the device when used.

[0034] A connecting groove 33 is provided at the bottom end of the connecting plate 27, and the connecting groove 33 is communicated with the second cavity 32. A push rod 34 is inserted into the interior of the connecting groove 33. By holding the push rod 34 and pushing it upward, the push rod 34 drives the limit plug 39 to squeeze the compression spring 31 and shrink inward, so that the limit plug 39 is no longer connected to the second cavity 32 for limiting. The operation is simple and convenient, which is convenient for the staff to operate and use the device.

[0035] A tension spring 35 is fixedly installed in the connecting plate 27 at the bottom end of the inner wall of the second cavity 32, and there are two tension springs 35. The top ends of the two tension springs 35 are fixedly connected to the bottom end of the push rod 34 inside the second cavity 32. When the push rod 34 moves upward in the second cavity 32, the push rod 34 drives the tension spring 35 to stretch and deform. When the force on the push rod 34 stops, the elastic force generated by the stretching of the tension spring 35 is released, and the push rod 34 is reset to move downward and fix the position of the push rod 34, thereby reducing the up and down movement of the push rod 34 in the second cavity 32 during operation, thereby affecting the use of the device, thereby improving the stability of the device during operation.

[0036] Working principle: When the screen shaft 7 rotates during use, it drives the screen shaft pulley 11 to rotate, thereby driving the V-belt 12 to rotate. Since the screen shaft pulley 11, the V-belt 12 and the cleaning shaft pulley 13 cooperate with each other to form a power mechanism, the rotating square shaft 18 rotates at this time, so that the cleaning teeth 16 on the rotating square shaft 18 sequentially clean the materials between the screen plates 8 on the screen shaft 7. When the rotating square shaft 18 rotates, the rotating square shaft 18 drives the first bevel gear 21 to rotate. Since the second bevel gear 22 at the bottom of the first bevel gear 21 is connected to the first bevel gear 16, the cleaning teeth 16 on the rotating square shaft 18 can clean the materials between the screen plates 8 on the screen shaft 7. The wheel 21 is meshed, so the second bevel gear 22 is forced to rotate at this time, and drives the rotating shaft 23 to rotate, and the rotating shaft 23 is fixedly connected to the half gear 24, so the half gear 24 is forced to rotate at this time, and the teeth on the half gear 24 are meshed with the teeth in the sliding frame 25. Therefore, when the half gear 24 rotates, it drives the sliding frame 25 to move left and right on the fixed frame 26. At this time, the sliding frame 25 drives the sponge plate 28 on the left connecting plate 27 to move left and right, so as to move and fit with one end of the fixed frame 26, and absorb the material adhered to one end of the fixed frame 26.

[0037] When the cleaning tooth 16 is worn, the square shaft through hole 19 no longer connects and fixes the cleaning tooth 16 to the rotating square shaft 18 by screwing the fixing bolt 17 on the worn cleaning tooth 16, so that a single worn cleaning tooth 16 can be replaced. When the connecting plate 27 and the sponge plate 28 need to be cleaned, repaired or replaced, the push rod 34 is held and pushed upward. At this time, the push rod 34 moves upward in the second cavity 32 and drives the tension spring 35 to stretch and deform. When the push rod 34 moves to a certain position, the top end of the push rod 34 fits with the bottom end of the limit plug 39. When continuing to move, the push rod 34 drives the limit plug 39 to squeeze the compression spring 31 and compress and deform. When the limit plug 39 moves to a certain position, the limit plug 39 is no longer connected and limited with the second cavity 32. At this time, the connecting plate 27 is no longer connected and fixed with the plug plate 38. At this time, the connecting plate 27 and the plug plate 38 can be disassembled for repair and replacement.

[0038] During installation, the slot 29 is aligned with the plug board 38 and inserted. When inserted, the right side of the connecting plate 27 squeezes the limiting plug block 39. At this time, the left side of the limiting plug block 39 is subjected to force. Since the left side of the limiting plug block 39 is an arc-shaped surface, when the left side of the limiting plug block 39 is subjected to force, the limiting plug block 39 moves inward, thereby driving the compression spring 31 to compress and deform. When the plug board 38 is fully inserted into the interior of the slot 29, the elastic potential energy generated by the compression of the compression spring 31 is released, and the elastic force generated by the reset drives the limiting plug block 39 to be inserted into the interior of the second cavity 32. At this time, the limiting plug block 39 and the second cavity 32 limit each other, thereby connecting the plug board 38 and the connecting plate 27 and limiting the position. At this time, the installation of the device is completed.

[0039] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
