The support rods 37 can support the outer shell 2, and the support block 38 can support the conveying box 31. Among them, in order to achieve the purpose of transmission, the present device adopts the following technical solution: Two connecting blocks 39 are fixedly connected to one side of the conveying box 31. A motor 40 is fixedly connected to the bottom of one of the connecting blocks 39. The output shaft of the motor 40 is fixedly connected to a worm 41. The worm 41 penetrates through the two connecting blocks 39. Worm wheels 42 meshing with the worm 41 are arranged on both the front and rear sides of the worm 41. The two worm wheels 42 are respectively fixedly sleeved outside the two second rotating shafts 25. The worm 41 is connected to the two connecting blocks 39 through bearings. A third gear 43 is fixedly sleeved outside the top of the worm 41. A fourth gear 44 meshing with the third gear 43 is arranged on one side of the third gear 43. The fourth gear 44 is fixedly sleeved on the top of the third rotating shaft 35. Sprockets 45 are fixedly sleeved on both the worm 41 and the rotating plate 5. A chain 46 is sleeved outside the two sprockets 45. The two sprockets 45 are drivingly connected through the chain 46. Two through holes are formed in the outer shell 2. The chain 46 penetrates through the two through holes. The designs of the motor 40, the worm 41, the worm wheels 42, the chain 46, the sprockets 45, the third gear 43, and the fourth gear 44 can realize the simultaneous rotation of the second rotating shaft 25, the rotating plate 5, and the spiral blades 36; Among them, in order to achieve the purpose of reducing wear, the present device adopts the following technical solution: The rotating plate 5 is connected to the connecting plate 4 through a bearing, the first rotating shaft 12 is connected to the connecting block 11 through a bearing, and the reciprocating lead screw 16 is connected to the support block 15 through a bearing. The bearing connection can reduce wear.

[0019] The use process of the present invention is as follows: When the solid waste of the injection molded parts needs to be recycled, the waste is added to the storage box 3. Then, the motor 40 is controlled to work. The motor 40 drives the worm 41 to rotate when it works. The worm 41 rotates to make the chain 46 rotate. The chain 46 rotates to drive the rotating plate 5 to rotate. In this way, the four distribution boxes 8 can be rotated, so that the four distribution boxes 8 take turns to move past the bottom end of the blanking pipe 21. When moving past, the waste will fall into the distribution box 8 through the blanking pipe 21 and the ring 9 on the distribution box 8. In this way, when the four distribution boxes 8 take turns to move past, waste will fall into all four distribution boxes 8; Among them, when the four distribution boxes 8 perform circular motion in the outer shell 2, the second gear 20 on the distribution box 8 will mesh with the annular gear ring, so that the reciprocating lead screw 16 can rotate. The reciprocating lead screw 16 rotates to drive the sliding seat 17 to move up and down once, so that the pull rod 18 and the toothed plate 19 can move up and down once. Then, under the action of the two first gears 14, the two first rotating shafts 12 can rotate back and forth once. The two first rotating shafts 12 rotate to drive the two baffles 13 to rotate. In this way, the two baffles 13 can flip back and forth once. When flipping back and forth, the waste in the distribution box 8 can fall, so that intermittent blanking can be realized, which can avoid excessive waste falling at one time, and further avoid the phenomenon of blockage; When the waste material falls from the material distribution box 8, it will fall between the two crushing wheels 26 through the discharge hopper 7. When the worm 41 rotates, it can also cause the two worm wheels 42 to rotate. The rotation of the two worm wheels 42 drives the rotation of the two second rotating shafts 25, so that the two crushing wheels 26 can rotate. In this way, the two crushing wheels 26 can crush the waste material. Then the crushed waste material falls onto the blanking plate 28. Since the blanking plate 28 is arranged in an inclined shape, the waste material can enter the conveying box 31 through the material shell 34. When the worm 41 rotates, it can also cause the third gear 43 to rotate. The rotation of the third gear 43 drives the rotation of the fourth gear 44. The rotation of the fourth gear 44 drives the rotation of the third rotating shaft 35. The rotation of the third rotating shaft 35 drives the rotation of the spiral blade 36. The rotation of the spiral blade 36 can convey the crushed waste material upward. Then the waste material returns to the storage box 3 through the return pipe 33, and then enters the material distribution box 8 again and falls between the two crushing wheels 26 by the same principle. In this way, cyclic crushing can be realized, so that the quality of crushing can be guaranteed during the recycling and crushing process of the waste material, which is convenient for later processing; After the crushing is completed, rotate the blanking plate 28 so that it rotates 90 degrees with the column 29 as the rotation axis. In this way, the right end of the blanking plate 28 will point to the front side, and the crushed waste material can be discharged from the device.

[0020] The above is only a preferred embodiment of the present invention. Any person skilled in the art may modify the present invention by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present invention shall fall within the scope of protection required by the present invention.
