[0026] In the above structure, large waste particles are discharged through the left extension groove 14, so that the large waste particles are located on the left side of the bottom shell 10, and small waste particles are discharged through the right extension groove 17, so that the small waste particles are located on the right side of the bottom shell 10.
[0027] In a preferred embodiment: the top of the top sieve plate 11 is provided with a plurality of sieve holes 12, the lowest point of the top sieve plate 11 is located on the left side of the bottom shell 10, and the lowest point of the bottom plate 15 is located on the right side of the bottom shell 10.
[0028] In the above structure, the screen holes 12 allow small waste materials to fall onto the bottom plate 15 through the screen holes 12. The top screen plate 11 and the bottom plate 15 are both in an inclined state, allowing large waste materials on the top screen plate 11 to roll towards the left extension groove 14, and small waste materials on the bottom plate 15 to roll towards the right extension groove 17.
[0029] In a preferred embodiment: a ring block 21 is installed at the bottom of the bottom housing 10. The bottom of the ring block 21 has several triangular grooves 22. A roller 23 is provided at the bottom of the ring block 21. A connecting piece 24 is movably connected to the outer edge of the roller 23. The inner wall of the connecting piece 24 is fixedly sleeved on the power output shaft of the bottom motor 26. The bottom motor 26 is fixed on the base 19 by a fixing bracket 25.
[0030] In the above structure, the power output shaft of the bottom motor 26 drives the connecting piece 24 to rotate. The rotation of the connecting piece 24 drives the roller 23 to rotate on the ring block 21. When the connecting piece 24 and the roller 23 rotate, they will push the ring block 21 upward and then enter the triangular groove 22, so that the bottom shell 10 can move up and down, so that the waste on the top screen plate 11 and the bottom plate 15 can be vibrated, so that the waste can be screened.

[0033] Working principle: During use, waste material is placed in the top housing 1. The power output shaft of the crushing motor 9 rotates clockwise, driving the first turntable 8 to rotate. The rotation of the first turntable 8 drives the belt 7 to rotate, which in turn drives the second turntable 6 to rotate. The rotation of the second turntable 6 drives the left rotating shaft 3 to rotate. At this time, gear 201 on the left rotating shaft 3 drives gear 201 to rotate, causing the right rotating shaft 2 to rotate along with gear 201. Simultaneously, the right-side slice group 4 and the left-side slice group 5 rotate, and the waste material is crushed by the shearing force of the right-side slice group 4 and the left-side slice group 5. Simultaneously, the power output shaft of the bottom motor 26 rotates, driving the connecting plate 24 to... As the connecting piece 24 rotates, the roller 23 rotates at the bottom of the ring block 21. The roller 23 pushes the ring block 21 and the bottom shell 10 upward. When the roller 23 is in the triangular groove 22, the ring block 21 and the bottom shell 10 move downward, allowing the bottom shell 10 to move up and down. The crushed waste falls onto the top screen plate 11, and the small waste falls onto the bottom plate 15 through the screen holes 12. The large waste rolls on the top screen plate 11 towards the left extension groove 14, and the small waste on the bottom plate 15 rolls towards the right extension groove 17, so that the large waste is on the left side of the bottom shell 10 and the small waste is on the right side of the bottom shell 10.
