The outer sides of the drive roller 21 and the driven roller 22 are provided with shearing teeth 23, and the shearing teeth 23 of the drive roller 21 and the driven roller 22 mesh with each other. A mounting base 26 is fixedly installed on one outer surface of the crushing bin 2. A reversible motor 25 is fixedly installed on the outer side of the mounting base 26. The output shaft of the reversible motor 25 is fixedly connected to one end of the drive roller 21. A belt 24 is provided between the outer sides of the drive roller 21 and the driven roller 22.

[0015] In this embodiment, a feeding bin 1, a crushing bin 2, and a discharging bin 3 are arranged sequentially from top to bottom. A feeding port 11 is provided at the top of the feeding bin 1. Inside the feeding port 11, two relatively movable closing plates 12 are provided, and a drive mechanism is provided to activate them, so that the closing plates 12 can be opened and closed conveniently and quickly. Thus, the feeding port 11 is open when feeding rubber and closed when crushing rubber. This ensures that when the device is crushing rubber, it prevents personnel from accidentally touching the inside of the crushing bin 2, and also prevents the rubber in the crushing bin 2 from splashing during crushing, thereby ensuring the safety of the device during operation. Inside the crushing bin 2, a relatively rotating drive roller 21 and a driven roller 22 are provided. Inside the drive roller 21 and the driven roller 22, mutually meshing shearing teeth 23 are provided, so that the rubber can be crushed quickly and thoroughly.

[0016] Specifically, a chute 101 is provided in the middle of the feeding bin 1. Two closing plates 12 are movably installed inside the chute 101. A sealing protrusion 122 is provided on one side of one of the closing plates 12, and a sealing groove 121 integrally formed therewith is provided on one side of the other closing plate 12. The sealing groove 121 and the sealing protrusion 122 are corresponding and compatible.

[0017] In this embodiment, by providing a sealing groove 121 and a sealing protrusion 122 on one side of each of the two closing plates 12, when the two closing plates 12 come close to each other and close, the sealing protrusion 122 enters the interior of the sealing groove 121, thereby completely closing the two closing plates 12 and preventing the rubber in the crushing chamber 2 from splashing.

[0018] Specifically, the drive mechanism includes a rotating component 15 rotatably mounted on the outside of the feeding bin 1. A driven gear 16 is fixedly sleeved on the outside of the middle position of the rotating component 15. A driving gear 17 is meshed directly below the driven gear 16. A reversible motor 18 is fixedly mounted on the outer surface of one side of the feeding bin 1. The output shaft of the reversible motor 18 is fixedly connected to the driving gear 17. Threaded rods 14 are screwed into the interior of both ends of the rotating component 15. The threads of the two threaded rods 14 are opposite in direction. The interior of the rotating component 15 has threaded grooves that are compatible with the two threaded rods 14. A fixing plate 13 is fixedly connected to the end of the threaded rod 14 away from the rotating component 15. The fixing plate 13 is fixedly connected to the outside of the closing plate 12. A control switch 27 is fixedly mounted on the front outer surface of the crushing bin 2. The control switch 27 is electrically connected to the reversible motor 18 and the reversible motor 25, respectively.

[0019] In this embodiment, a drive mechanism for the relative movement of two closing plates 12 is provided on the outside of the feeding bin 1. Under the action of the drive mechanism, when it is necessary to close the two closing plates 12, the forward and reverse motor 18 is first started by the control switch 27. Under the action of the forward and reverse motor 18, the drive gear 17 starts to rotate, thereby driving the driven gear 16 to rotate. The driven gear 16 drives the rotating part 15 to rotate. When the rotating part 15 rotates, the two threaded rods 14 screwed on both ends of the rotating part 15 move simultaneously, thereby driving the two closing plates 12 to move closer to each other through the fixed plate 13, thereby achieving the purpose of closing the feeding port 11. To open the two closing plates 12, the forward and reverse motor 18 can be started in reverse.

[0020] Specifically, the discharge bin 3 is located directly below the crushing bin 2, and the bottom surface of the discharge bin 3 is an inclined surface 32. A discharge port 31 is opened on one side of the lower end of the discharge bin 3, and the discharge port 31 is located at the lower end of the inclined surface 32.

[0021] In this embodiment, an inclined surface 32 is provided at the bottom of the inner part of the discharge bin 3, and a discharge port 31 is opened at the lower end of the inclined surface 32, so that the rubber fragments after crushing can be moved to the discharge port 31, which makes it easier for workers to collect them.

[0022] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
