Multiple wheel brushes are provided, with support springs and telescopic cleaning brushes fixedly connected between each adjacent wheel brush. The telescopic cleaning brush is sleeved on the outside of the support spring. A limit ring is fixedly connected to one side of the outermost wheel brush. An upper synchronous pulley is rotatably connected to one side of the limit ring. A first sliding sleeve is fixedly connected inside the upper synchronous pulley. The first sliding sleeve is sleeved on the outside of the rotating rod. A limit frame is rotatably connected to the outside of the first sliding sleeve. A drive shaft is movably connected inside the bottom end of the limit frame. A support plate is rotatably connected to one end of the drive shaft extending to the outside of the limit frame. A limit sleeve is fixedly connected to one side of the support plate. A second sliding sleeve is rotatably connected inside the limit sleeve. A guide shaft passes through the second sliding sleeve and is slidably connected to the second sliding sleeve.

[0007] Preferably, a third bevel gear is fixedly connected to one end of the rotating shaft, and a fourth bevel gear is fixedly connected to one end of the guide shaft. The third bevel gear and the fourth bevel gear mesh with each other. A second limiting groove is provided on both sides of the guide shaft. A second limiting plate is integrally formed on both sides of the inside of the second sliding sleeve. The two second limiting plates are slidably connected to the outside of the two second limiting grooves and are adapted to the second limiting grooves. The second limiting grooves limit the second limiting plates, thereby driving the second sliding sleeve to rotate.

[0008] Preferably, a lower synchronous pulley is rotatably connected to one side of the bottom of the limiting frame, and a third limiting plate is integrally formed on both sides of the lower synchronous pulley. A third limiting groove is opened on both sides of the transmission shaft. The two third limiting plates are slidably connected to the outside of the two third limiting grooves and are adapted to the two third limiting grooves. A synchronous belt is tensioned and sleeved on the outside of the upper and lower synchronous pulleys.

[0009] Preferably, a first bevel gear is fixedly connected to one side of the second sliding sleeve, and a second bevel gear is fixedly connected to one end of the transmission shaft extending to the outer side of the support plate. The second bevel gear meshes with the first bevel gear, and the first bevel gears on both sides are located at opposite positions of the two second bevel gears, driving the two second bevel gears to rotate in the same direction.

[0010] Preferably, the inner ring of the brush has multiple first limiting plates integrally formed, and the outer side of the rotating rod has multiple first limiting grooves. The multiple first limiting plates are slidably connected to the inner side of the multiple first limiting grooves and are adapted to the multiple first limiting grooves. The inner side of the first sliding sleeve has multiple fourth limiting plates integrally formed, and the multiple fourth limiting plates are slidably connected to the outer side of the multiple first limiting grooves and are adapted to the multiple first limiting grooves. The first limiting grooves limit the first limiting plates, so that when the rotating rod rotates, it drives the multiple brushes to rotate, and the brushes can move horizontally on the outer side of the rotating rod.

[0011] Preferably, the limiting frame has an installation groove inside, and a collection box is provided between the two limiting frames. The collection box is fixed on both sides and is installed between the two limiting frames through the two fixing plates. The top two sides of the collection box are fixedly connected to guide plates to facilitate the guidance of debris and make it easy to collect.

[0012] Preferably, a sliding plate is sleeved on the outer side of the limiting frame, and support plates are fixedly connected to both sides of the sliding plate. A strong tension spring is fixedly connected to the bottom of the support plate. Two connecting plates are fixedly connected to one side of the side plate, and the bottom ends of the two strong tension springs are respectively fixedly connected to the two connecting plates. This facilitates the stretching of the side plate, so that the side plate always has an upward force.

[0013] Preferably, a piston cylinder is fixedly connected to one end of the support plate, a piston plate is slidably connected inside the piston cylinder, the piston cylinder is filled with buffer solution, and multiple through holes are arranged in a ring array inside the piston plate. A sliding rod is fixedly connected to one side of the piston plate, the sliding rod passes through the end wall of the piston cylinder and is slidably connected to the piston cylinder, and two fixing blocks are fixedly connected to one side of the side plate. The bottom ends of the two sliding rods are respectively fixedly connected to the two fixing blocks to form a damping effect. This, together with a strong tension spring, buffers the side plate and improves its stability.

[0014] Preferably, a threaded rod is rotatably connected inside the sliding plate, a handle is fixedly connected to one end of the threaded rod, a movable plate is threadedly connected to the outside of the threaded rod, and two positioning pins are fixedly connected to one side of the movable plate. Rotating the threaded rod causes the movable plate and positioning pins to move.

[0015] Preferably, both positioning pins penetrate the sliding plate and are slidably connected to it. The limiting frame has multiple positioning holes inside, and the positioning pins are adapted to the positioning holes. The sliding plate is fixed by inserting the positioning pins into the positioning holes.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This application enables the limiting frame to push the wheel brushes to slide on the outside of the rotating rod, and the wheel brushes on both sides move towards the middle, squeezing multiple support springs and telescopic cleaning brushes. At the same time, it reduces the distance between multiple wheel brushes. It is adjusted in conjunction with the width of the belt. After adjustment, the top of the limiting frame is locked at the bottom of the conveyor to limit the multiple wheel brushes. Alternatively, bolts can be used to fix the limiting frame to the bottom of the conveyor. The width of the multiple wheel brushes and telescopic cleaning brushes is consistent with the width of the belt, which is conducive to adaptive adjustment according to the width of the belt, and is convenient and quick.

[0017] 2. This application involves two rubber wheels engaging with the rubber toothed belts on both sides of the conveyor belt, while multiple wheel brushes also engage with the bottom of the conveyor belt. The belt is cleaned by multiple wheel brushes and multiple telescopic cleaning brushes. When the side plate moves, it drives the fixed block to move, which in turn drives the slide rod to move. The slide rod then drives the piston plate to slide inside the piston cylinder. As the piston plate moves, the buffer solution inside the piston cylinder flows through the through holes inside the piston plate, creating a damping effect. This, combined with the elasticity of the strong tension spring, buffers the side plate, thereby improving its stability. This ensures that the side plate, along with the two rubber wheels and wheel brushes, maintains stable contact with the bottom of the belt.

[0018] 3. This application enables the limiting sleeve to rotate under the limit of the guide shaft, thereby automatically adapting the limiting sleeve to the angle change between the guide shaft and the limiting frame, allowing the guide shaft to slide inside the second sliding sleeve. The guide shaft and the second sliding sleeve can also maintain synchronization, allowing the guide shaft to drive the second sliding sleeve to rotate. This is beneficial for installation on conveyors with different inclinations, is convenient to use, has a wide range of applications, is easy to adjust, and does not require an additional power source, as it can be used with the power of the conveyor itself.

[0019] 4. When the rotating rod rotates, the first limiting groove on its outer side limits the first limiting plate, thereby driving the wheel brush to rotate synchronously. At this time, the rotation direction of the wheel brush is opposite to the rotation direction of the rubber wheel, so that the transmission direction of the wheel brush and the belt is opposite. This causes multiple wheel brushes and multiple telescopic cleaning brushes to roll at the bottom of the belt, cleaning the debris adhering to the belt and causing the debris to fall into the collection box. The guide plate guides the debris to prevent splashing. The collection box can be kept vertically set under the support of the limiting frame, which facilitates the collection and storage of debris and prevents the debris from spilling out due to tilting.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example: Figures 1-15As shown, the present invention provides a technical solution for an adjustable belt cleaning device that can remove debris adhering to a belt. It includes a conveyor 1, with mounting plates 2 installed on both sides of the conveyor 1. Mounting frames 3 are fixedly connected to the bottom of each mounting plate 2. Side plates 4 are provided at the bottom of the mounting frames 3. A rotating shaft 5 is rotatably connected to one end of each side plate 4. Rubber wheels 6 are fixedly connected to the outer sides of both ends of the rotating shaft 5. Rubber toothed belts 49 are fixedly connected to both sides of the conveyor belt 1. The two rubber wheels 6 respectively mesh with the two rubber toothed belts 49. An L-shaped plate 7 is rotatably connected to one end of the rotating shaft 5 extending to the outer side of the side plate 4. A guide shaft 8 is rotatably connected inside the L-shaped plate 7. A rotating rod 9 is provided inside the other end of the side plate 4. Multiple wheel brushes 10 are sleeved on the outer side of the rotating rod 9. The wheel brushes 10 have internal... The annular array is integrally formed with multiple first limiting plates 11. Multiple first limiting grooves 12 are formed on the outer side of the rotating rod 9. The multiple first limiting plates 11 are slidably connected to and adapted to the multiple first limiting grooves 12. Multiple fourth limiting plates 48 are integrally formed inside the first sliding sleeve 16. The multiple fourth limiting plates 48 are slidably connected to and adapted to the outer side of the multiple first limiting grooves 12. The first limiting grooves 12 limit the first limiting plates 11, causing the rotating rod 9 to rotate and drive multiple wheel brushes 10 to rotate, allowing the wheel brushes 10 to move horizontally outside the rotating rod 9. Support springs 15 and telescopic cleaning brushes 14 are fixedly connected between multiple adjacent wheel brushes 10. Located outside the support spring 15, a limiting ring 13 is fixedly connected to one side of the outermost wheel brush 10. An upper synchronous pulley 30 is rotatably connected to one side of the limiting ring 13. A first sliding sleeve 16 is fixedly connected inside the upper synchronous pulley 30. The first sliding sleeve 16 is fitted onto the outside of the rotating rod 9. A limiting frame 47 is rotatably connected to the outside of the first sliding sleeve 16. A drive shaft 17 is movably connected inside the bottom end of the limiting frame 47. A support plate 18 is rotatably connected to one end of the drive shaft 17 extending to the outside of the limiting frame 47. A limiting sleeve 19 is fixedly connected to one side of the support plate 18. A second sliding sleeve 20 is rotatably connected inside the limiting sleeve 19. A first bevel gear 23 is fixedly connected to one side of the second sliding sleeve 20. A second bevel gear 24 is fixedly connected to one end of the drive shaft 17 extending to the outside of the support plate 18. The first bevel gear 23 is meshed with the second bevel gear 24, which is located on opposite sides of the first bevel gear 23, driving the two second bevel gears 24 to rotate in the same direction. The guide shaft 8 passes through the second sliding sleeve 20 and is slidably connected to it. One end of the rotating shaft 5 is fixedly connected to the third bevel gear 45, and one end of the guide shaft 8 is fixedly connected to the fourth bevel gear 46. The third bevel gear 45 and the fourth bevel gear 46 are meshed with each other. The guide shaft 8 has second limiting grooves 21 on both sides. The second sliding sleeve 20 has two integrally formed second limiting plates 22 on both sides inside. The two second limiting plates 22 are slidably connected to the outside of the two second limiting grooves 21 and are adapted to the second limiting grooves 21. The second limiting grooves 21 limit the second limiting plates 22.This drives the second sliding sleeve 20 to rotate. A lower synchronous wheel 27 is rotatably connected to one side of the bottom of the limiting frame 47. Both sides of the lower synchronous wheel 27 have integrally formed third limiting plates 29. Third limiting grooves 28 are provided on both sides of the drive shaft 17. The two third limiting plates 29 are slidably connected to the outside of the two third limiting grooves 28 and are adapted to fit the two third limiting grooves 28. A synchronous belt 31 is tensioned and fitted on the outside of the upper synchronous wheel 30 and the lower synchronous wheel 27. The two drive shafts 17 are supported and limited by the fixing plate 26.

[0024] The limiting frame 47 has an installation slot inside, and a collection box 32 is set between the two limiting frames 47. A fixing plate 26 is installed on both sides of the collection box 32. The two sides of the collection box 32 are installed between the two limiting frames 47 through the two fixing plates 26. A guide plate 33 is fixedly connected to both sides of the top of the collection box 32 to facilitate the guidance of debris and collection.

[0025] A sliding plate 34 is fitted on the outer side of the limiting frame 47. Support plates 35 are fixedly connected to both sides of the sliding plate 34. A strong tension spring 36 is fixedly connected to the bottom of the support plate 35. Two connecting plates 41 are fixedly connected to one side of the side plate 4. The bottom ends of the two strong tension springs 36 are fixedly connected to the two connecting plates 41 respectively, which is conducive to stretching the side plate 4 and keeping the side plate 4 always having an upward force. A piston cylinder 37 is fixedly connected to one end of the support plate 35. A piston plate 38 is slidably connected inside the piston cylinder 37. The piston cylinder 37 is filled with buffer solution. The piston plate 38 has multiple through holes in a ring array inside. A sliding rod 39 is fixedly connected to one side of the piston plate 38. The sliding rod 39 passes through the end wall of the piston cylinder 37 and is slidably connected to the piston cylinder 37. Two fixing blocks 40 are fixedly connected to one side of the side plate 4. The bottom ends of the two sliding rods 39 are fixedly connected to the two fixing blocks 40 respectively, forming a damping effect. Together with the strong tension spring 36, the side plate 4 is buffered, improving the stability of the side plate 4.

[0026] A threaded rod 43 is rotatably connected inside the sliding plate 34. A handle is fixedly connected to one end of the threaded rod 43. A movable plate 42 is threadedly connected to the outside of the threaded rod 43. Two positioning pins 44 are fixedly connected to one side of the movable plate 42. Rotating the threaded rod 43 causes the movable plate 42 and the positioning pins 44 to move. Both positioning pins 44 pass through the sliding plate 34 and are slidably connected to the sliding plate 34. The limiting frame 47 has multiple positioning holes 25 inside. The positioning pins 44 are adapted to the positioning holes 25. The sliding plate 34 is fixed by inserting the positioning pins 44 into the positioning holes 25.

[0027] In use, the device is placed at the bottom of conveyor 1, and the mounting plates 2 on both sides are bolted to both sides of conveyor 1. The installation position between the two mounting plates 2 and conveyor 1 can be adjusted with bolts to accommodate conveyors 1 of different widths. By pushing the limiting frames 47 on both sides, the limiting frames 47 push the wheel brushes 10 to slide outside the rotating rod 9. The wheel brushes 10 on both sides move towards the center, compressing the multiple support springs 15 and telescopic cleaning brushes 14, and reducing the distance between the multiple wheel brushes 10. This is adjusted in conjunction with the width of the belt. After adjustment, the top of the limiting frame 47 is locked at the bottom of conveyor 1 to limit the multiple wheel brushes 10. Alternatively, the limiting frame 47 can be fixed to the bottom of conveyor 1 with bolts. The width of the multiple wheel brushes 10 and telescopic cleaning brushes 14 is consistent with the width of the belt, which is convenient and quick to adjust according to the width of the belt. When the limiting frame 47 moves, its bottom drives the lower synchronous wheel 27 to move, so that the lower synchronous wheel 27 moves outside the drive shaft 17 to accommodate the adjustment of the wheel brushes 10.

[0028] After the sliding plate 34 slides on the outside of the mounting bracket 3 and the initial position is adjusted, the moving plate 42 is moved by rotating the threaded rod 43. The moving plate 42 moves the positioning pin 44, thereby pushing the positioning pin 44 into the positioning hole 25 to fix the sliding plate 34 and the support plate 35. The initial position of the support plate 35 is adjusted. The large pulling force of the strong tension spring 36 drives the connecting plate 41 and the side plate 4 upward, so that the side plate 4 drives the rotating shaft 5 upward. This makes the two rubber wheels 6 mesh with the bottom of the rubber toothed belt 49 on both sides of the conveyor belt 1, and at the same time, the multiple wheel brushes 10 also mesh with the bottom of the conveyor belt 1. The belt is cleaned by multiple wheel brushes 10 and multiple telescopic cleaning brushes 14. When the side plate 4 moves, it drives the fixed block 40 to move, which in turn drives the slide rod 39 to move. The slide rod 39 drives the piston plate 38 to slide inside the piston cylinder 37. As the piston plate 38 moves, the buffer solution inside the piston cylinder 37 flows through the through hole inside the piston plate 38, creating a damping effect. This, combined with the elastic force of the high-strength tension spring 36, buffers the side plate 4, thereby improving the stability of the side plate 4. This ensures that the side plate 4, along with the two rubber wheels 6 and wheel brushes 10, maintains a stable fit with the bottom of the rubber toothed belt 49. The high-strength tension spring 36 provides a continuous upward pulling force to the side plate 4 through the sliding plate 34 and the connecting plate 41, thereby creating a stable and sufficient contact pressure between the rubber wheels 6 and the lower surface of the belt.

[0029] Because the rubber wheel 6 meshes with the rubber toothed belts 49 on both sides of the belt, the belt moves and drives the two rubber wheels 6 to roll. The rolling of the rubber wheels 6 drives the rotating shaft 5 to rotate, which in turn drives the third bevel gear 45 to rotate. The third bevel gear 45 then drives the fourth bevel gear 46 to rotate, thereby rotating the guide shaft 8. When the guide shaft 8 rotates, the multiple second limiting grooves 21 on its outer side limit the second limiting plate 22, causing the guide shaft 8 to rotate and drive the second sliding sleeve 20 to rotate. Furthermore, when the angle of the limiting frame 47 changes... This causes the limiting frame 47 to move the support plate 18 and the limiting sleeve 19, and the limiting sleeve 19 to rotate under the limit of the guide shaft 8. This allows the limiting sleeve 19 to automatically adapt to the angle change between the guide shaft 8 and the limiting frame 47, so that the guide shaft 8 slides inside the second sliding sleeve 20. The guide shaft 8 and the second sliding sleeve 20 can also keep synchronized, so that the guide shaft 8 drives the second sliding sleeve 20 to rotate. This is beneficial for adapting to the installation of conveyors 1 with different inclinations, making it convenient to use, with a wide range of applications, easy to adjust, and requiring no additional power source. It can be used by the power of the conveyor 1 itself.

[0030] When the second sliding sleeve 20 rotates, it drives the first bevel gear 23 to rotate. The first bevel gear 23 then drives the second bevel gear 24 to rotate. The second bevel gear 24 then drives the transmission shaft 17 to rotate, which in turn drives the lower synchronous pulley 27 to rotate. The lower synchronous pulley 27 then drives the synchronous belt 31 and the upper synchronous pulley 30 to rotate. This causes the upper synchronous pulley 30 to rotate, which in turn drives the first sliding sleeve 16 to rotate. The first sliding sleeve 16 then drives the rotating rod 9 to rotate. When the rotating rod 9 rotates, its outer first limiting groove 12 limits the first limiting plate 11. The position drives the wheel brush 10 to rotate synchronously, and at this time the rotation direction of the wheel brush 10 is opposite to the rotation direction of the rubber wheel 6, so that the transmission direction of the wheel brush 10 and the belt is opposite, causing multiple wheel brushes 10 and multiple telescopic cleaning brushes 14 to roll at the bottom of the belt, cleaning the debris adhering to the belt, and causing the debris to fall into the collection box 32. The debris is guided by the guide plate 33 to prevent splashing, and the collection box 32 can be kept vertically set under the support of the limiting frame 47, which facilitates the collection and storage of debris and prevents the debris from spilling out due to tilting.

[0031] It will be apparent to those skilled in the art that the present 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 its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
