[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] This utility model provides a dust-free waste rubber shredder. Rubber is placed into the shredding drum for crushing. Then, the sealing cover is rotated, and the hand-tightened bolts ensure a tight seal between the cover and the drum, preventing dust from escaping. Starting the motor drives the entire shredder to rotate. Simultaneously, a small helical gear on the U-shaped plate meshes with a large helical gear on the fixed plate, causing the second pulley to rotate. The second pulley, via a transmission belt, drives the first pulley. The first pulley, through a connecting rod, causes the second gear to drive the first gear, which in turn rotates the crushing roller inside the drum. This process prevents waste rubber from accumulating while simultaneously crushing the waste rubber, increasing the crushing effect.

[0026] like Figure 1-6 As shown, this utility model discloses a dust-free waste rubber shredder, comprising a fixed plate 1 and a base 24. The base 24 is welded to the bottom of the fixed plate 1. A large helical gear 12 is welded to the surface of the fixed plate 1. A motor 2 is mounted on the surface of the fixed plate 1. A rotating rod 16 is provided on the surface of the motor 2. A U-shaped plate 3 is fixedly connected to the other end of the rotating rod 16. A crushing cylinder 4 is fixedly connected to the surface of the U-shaped plate 3. A crushing roller 5 is connected to the inner side of the crushing cylinder 4 via a bearing. A first gear 6 is welded to the surface of the crushing roller 5. A second gear 7 is meshed with the surface of the first gear 6. A first pulley 8 is connected to the second gear 7 via a connecting rod. A transmission belt 9 is meshed with the surface of the first pulley 8. A second pulley 10 is meshed with the inner side of the transmission belt 9. A first transmission rod 11 is fixedly connected to the surface of the second pulley 10. A small helical gear 29 is fixedly connected to the other end of the first transmission rod 11. The surface of the small helical gear 29 is meshed with a large helical gear 12. This allows rubber to be placed into the crushing cylinder 4 for crushing. Then, the sealing cover is rotated, and the hand-tightening bolt 26 is tightened to ensure a tight seal on the crushing cylinder 4, preventing dust from escaping. The motor 2 is then started, causing the entire crusher to rotate. Simultaneously, the small helical gear 29 on the U-shaped plate 3 meshes with the large helical gear 12 on the fixed plate 1, causing the second pulley 10 to rotate. The second pulley 10, via the transmission belt 9, drives the first pulley 8 to rotate. The first pulley 8, via the connecting rod, causes the second gear 7 to drive the first gear 6 to rotate, thus causing the crushing roller 5 inside the crushing cylinder 4 to rotate. This prevents the accumulation of waste rubber while simultaneously causing the crushing roller 5 to rotate and crush the waste rubber, increasing the crushing effect.

[0027] A rigid water supply pipe 13 is connected to the surface of the crushing cylinder 4 via a sealed bearing. A water tank 15 is fixedly connected to the other end of the water supply pipe. A pump body 14 is installed on the top of the water tank 15. When the crushing cylinder 4 rotates to crush waste rubber, the pump body 14 is activated, and water from the water tank 15 is fed into the crushing cylinder 4 through the rigid water supply pipe 13. In this way, the mud and dust on the surface of the waste rubber can be washed at the same time during the rotation crushing process.

[0028] A first transmission wheel 17 is welded to the surface of a rotating rod 16. A second transmission wheel 18 is connected to the surface of the first transmission wheel 17 via a transmission belt. A second transmission rod 19 is fixedly connected to the inner side of the second transmission wheel 18. A turntable 20 is fixedly connected to the surface of the second transmission rod 19. A protruding post 21 is welded to the surface of the turntable 20. A movable groove 22 is fitted onto the surface of the protruding post 21. A filter frame 23 is fixedly connected to the surface of the movable groove 22. The crushed and cleaned rubber falls into the filter frame 23. Then, the waste rubber is put back into the crushing cylinder 4. When the motor 2 is started, the rotating rod 16 connected to the motor 2 drives the first transmission wheel 17 to rotate. The first transmission wheel 17 drives the second transmission wheel 18 to rotate via a transmission belt. The second transmission wheel 18 drives the turntable 20 to rotate via the second transmission rod 19. At this time, the protruding post 21 on the turntable 20 will rotate centrifugally and drive the filter frame 23 to make a relatively fast back-and-forth reciprocating motion through the movable groove 22, which speeds up the outflow of water from the crushed rubber and increases the cleaning efficiency of the device.

[0029] The bottom of the filter frame 23 is attached to a roller 27, and the surface of the roller 27 is connected to a base 24 via a rotating shaft. In this way, the friction coefficient between the filter frame 23 and the base 24 is reduced by the roller 27, which facilitates the back-and-forth movement of the filter frame 23.

[0030] The base 24 has a stabilizing plate 28 welded to its surface. The stabilizing plate 28 is symmetrically distributed, which prevents the filter frame 23 from shaking during back-and-forth movement and increases the stability of the device.

[0031] A rotating cover 25 is connected to the surface of the crushing cylinder 4 via a rotating shaft. A hand-tightening bolt 26 is connected to the surface of the rotating cover 25 via a thread. The crushing cylinder 4 is connected to the surface of the hand-tightening bolt 26 via a thread. By rotating the sealing cover and tightening the hand-tightening bolt 26, the sealing cover is tightly connected to the crushing cylinder 4, preventing dust from escaping.

[0032] Combination Figures 1-6The specific operation process of the waste rubber dust-free crusher of this embodiment is as follows: When the rubber is put into the crushing cylinder 4 for crushing, the sealing cover is rotated and the hand-tightening bolt 26 is tightened to make the sealing cover tightly connected to the crushing cylinder 4 to prevent dust from escaping. Then, the motor 2 is started to drive the crusher to rotate. At the same time as the crusher rotates, the small helical gear 29 on the U-shaped plate 3 and the large helical gear 12 on the fixed plate 1 are meshed and rotated, thereby driving the second pulley 10 to rotate. The second pulley 10 drives the first pulley 8 to rotate through the transmission belt 9. The first pulley 8 drives the second gear 7 to rotate through the connecting rod, thereby causing the crushing roller 5 inside the crushing cylinder 4 to rotate. In this way, while preventing the accumulation of waste rubber during the rotation of the crusher, the crushing roller 5 is simultaneously rotated to crush the waste rubber, increasing the crushing effect.

[0033] In this embodiment, since the waste rubber may have a lot of mud and impurities adhering to it, it may be inconvenient to separate and clean it after crushing. Therefore, please refer to the following again. Figures 1-6 In this embodiment, when the crushing drum 4 rotates to crush waste rubber, the pump body 14 is started, and water from the water tank 15 is introduced into the crushing drum 4 through the rigid water pipe 13. This allows the surface of the waste rubber to be cleaned of dirt and dust during the rotational crushing process. After crushing, the sealing cover is opened by unscrewing the hand-tightening bolt 26, allowing the crushed and cleaned rubber to fall into the filter frame 23. Then, the waste rubber is put back into the crushing drum 4. At the same time as the motor 2 is started, the rotating rod 16 connected to the motor 2 drives the first transmission wheel 17 to rotate. The first transmission wheel 17 drives the second transmission wheel 18 to rotate through the transmission belt. The second transmission wheel 18 drives the turntable 20 to rotate through the second transmission rod 19. At this time, the protrusion 21 on the turntable 20 will drive the filter frame 23 to make a relatively fast back-and-forth reciprocating motion through the movable groove 22 via centrifugal rotation, which speeds up the outflow of water from the crushed rubber and increases the cleaning efficiency of the device.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
