[0031] When the pneumatic cylinder 6 moves, the moving block 7 will move upward driven by the pneumatic cylinder 6, and then the moving block 7 will drive the two moving rods 8 to move. At this time, the opposite ends of the two moving rods 8 will drive the two moving plates 10 to move through the two hinge blocks 9. Due to the design of the two limit blocks 3, the two moving plates 10 will move toward each other under the limit of the two limit blocks 3, thereby achieving the effect of automatically opening and closing the top of the crushing box 1, thereby preventing the rubber from splashing to the outside of the crushing box 1 when it is crushed inside the crushing box 1.

[0032] Among them, a fixing plate 11 is fixedly installed on the left side of the front of the crushing box 1, and a driving motor 12 is fixedly installed on the front of the fixing plate 11. The other end of the output shaft of the driving motor 12 is fixedly sleeved with a rotating shaft 13, and the other end of the rotating shaft 13 passes through the front of the fixing plate 11 and extends to the inside of the fixing plate 11. A first gear 14 is fixedly installed on the other end of the rotating shaft 13. There are two first gears 14. The opposite ends of the two first gears 14 are meshed and connected. The backs of the two first gears 14 are movably connected to the front of the crushing box 1.

A crushing roller 16 is fixedly sleeved on the outer surface of the round rod 15 located inside the crushing box 1, and the outer surface of the crushing roller 16 is movably connected to the inside of the crushing box 1.

[0033] When the driving motor 12 is running, the rotating shaft 13 will drive the two first gears 14 to rotate. Since the two first gears 14 are meshed and connected, the two first gears 14 will rotate in opposite directions. Then, the two first gears 14 will drive the two crushing rollers 16 to rotate in opposite directions through the two round rods 15. At this time, the rubber between the two crushing rollers 16 will be crushed in the opposite rotation of the two crushing rollers 16.

The other end of the long shaft 22 passes through the left side of the crushing box 1 and extends to the interior of the crushing box 1. The outer surface of the long shaft 22 located inside the crushing box 1 is fixedly sleeved with a vibration block 23, and the top end of the vibration block 23 is movably connected to the bottom end of the screen plate 17.

[0037] When the first power motor 21 is running, the long shaft 22 will drive the vibration block 23 to rotate. Since the vibration block 23 is elliptical in shape, the sieve plate 17 will vibrate up and down when the vibration block 23 rotates.

[0038] A square groove 24 is provided at the top of the back side of the fixed box 4 , a guide block 25 is fixedly installed at the top of the back side of the fixed box 4 , and the interior of the guide block 25 is connected to the interior of the crushing box 1 through a feed port 26 .

[0039] Due to the design of the interior of the guide block 25, when the large-volume rubber particles inside the fixed box 4 move to the interior of the guide block 25 through the square groove 24, the interior of the guide block 25 will guide the large-volume rubber particles. Then, the large-volume rubber particles will move to the interior of the crushing box 1 through the feed port 26, so that the large-volume rubber particles can be crushed for the second time.

[0040] Among them, the bottom end of the fixed box 4 is movably connected with a lifting plate 27, and a tooth plate 28 is fixedly installed on the right side of the top of the lifting plate 27.

[0042] Among them, a vertical plate 29 is fixedly installed on the top of the fixed box 4, and a second power motor 30 is fixedly installed on the back of the vertical plate 29. The other end of the output shaft of the second power motor 30 is fixedly sleeved with a rotating shaft 31. The other end of the rotating shaft 31 passes through the back of the vertical plate 29 and extends to the front of the front of the vertical plate 29. The outer surface of the other end of the rotating shaft 31 is fixedly sleeved with a second gear 32, and the outer surface of the second gear 32 is meshed with the outer surface of the toothed plate 28.

[0043] When the second power motor 30 moves, the rotating shaft 31 will drive the second gear 32 to rotate, and then the gear plate 28 will move upward under the drive of the second gear 32 .

[0044] The working principle and use process of this utility model:

[0045] First, the operator pours the rubber into the crushing box 1, and then the operator starts the pneumatic cylinder 6, which will drive the moving block 7 to move upward, and then the two moving rods 8 will move under the drive of the moving block 7, and then the two moving rods 8 will drive the two moving plates 10 to move through the two hinge blocks 9. Due to the design of the two limit blocks 3, the two moving plates 10 will move towards each other under the limit of the two limit blocks 3. When the facing ends of the two moving plates 10 are in contact, the top of the crushing box 1 will be in a closed state, thereby preventing the rubber from splashing to the outside of the crushing box 1 when being crushed. At this time, the operator starts the drive motor 12 At this time, the rotating shaft 13 will drive the first gear 14 to rotate. Since the two first gears 14 are meshed and connected, the two first gears 14 will rotate in opposite directions. Then, the two first gears 14 will drive the two crushing rollers 16 to rotate in opposite directions through the two round rods 15. At this time, the rubber on the top of the two crushing rollers 16 will be crushed in the opposite rotation of the two crushing rollers 16, and then the crushed rubber particles will fall to the top of the sieve plate 17. At this time, the rubber particles smaller than the mesh diameter of the sieve plate 17 will fall into the interior of the collecting box 2 through the sieve plate 17 to complete the collection, while the large-volume rubber particles larger than the mesh diameter of the sieve plate 17 will stay on the top of the sieve plate 17.

[0046] Then the operator starts the first power motor 21, at which time the long shaft 22 will drive the vibration block 23 to rotate. Due to the design of the shape of the vibration block 23, when the vibration block 23 rotates, the screen plate 17 will vibrate. Due to the design of the four vertical rods 18, the screen plate 17 can only vibrate up and down. Due to the design of the spring 19, a good reset effect will be provided for the movement of the screen plate 17. At this time, the large-volume rubber particles at the top of the screen plate 17 will move to the top of the lifting plate 27 through the discharge port 20 during the vibration of the screen plate 17. At this time, the operator starts the second power motor 30, and then the rotating shaft 31 will drive the second gear 32 to The toothed plate 28 will move upwards driven by the second gear 32, and the lifting plate 27 will move upwards driven by the toothed plate 28 at the same time. When the lifting plate 27 moves to the front of the square slot 24, the large-volume rubber particles at the top of the lifting plate 27 will move to the inside of the guide block 25 through the square slot 24. Due to the design of the inside of the guide block 25, the inside of the guide block 25 will guide the large-volume rubber particles. Finally, the large-volume rubber particles will move to the inside of the crushing box 1 through the feed port 26 under the guidance of the inside of the guide block 25, thereby realizing the function of multiple crushing of the large-volume rubber particles.
