By providing the device housing 1, the driving motor 2, the partition 3, the driving shaft 4, the first crushing piece 5, the first roller 6, the second crushing piece 7, the driving gear 8, the driven gear 9, the toothed ring 10, the planet carrier 11, the hollow shaft 12, the second roller 13 and the third crushing blade 14, the work of multi-stage screening and crushing is realized, thereby effectively improving the fineness of crushing, and it is realized by one motor, effectively reducing the operation energy consumption, and further reducing the crushing cost, meeting the work needs of people, and is worthy of popularization and use.

[0022] Furthermore, the partition 3 is distributed in an inclined shape, and through holes matching the partition 3 are arranged on the outer wall of the device housing 1, which facilitates the screening work.

[0023] Furthermore, the driving shaft 4 is connected through the hollow shaft 12 and penetrates through the partition 3, and the hollow shaft 12 is connected through a bearing and penetrates through the partition 3, which facilitates the support work.

[0024] Furthermore, through holes are arranged on the outer wall of the first roller 6, and the bottom wall of the first roller 6 is distributed in an inclined shape, which facilitates the screening work.

[0025] Furthermore, through holes are arranged on the outer wall of the second roller 13, and the bottom wall of the second roller 13 is distributed in an inclined shape, which facilitates the screening work.

[0026] Furthermore, the driving gear 8 meshes with the driven gear 9, the driven gear 9 meshes with the gear ring 10, the gear ring 10 is fixed to the bottom of the partition plate 3, and the driven gear 9 is rotatably connected to the planet carrier 11 through a shaft, which facilitates the driven gear 9 to rotate around its own axis while revolving around the sun gear.

[0027] During use, first start the drive motor 2, so that the drive motor 2 drives the drive shaft 4 to rotate, and the drive shaft 4 drives the first crushing piece 5 and the first roller 6 to rotate. Thus, under the action of centrifugal force, the object is crushed inside the first roller 6.

At this time, the first roller 6 drives the second crushing piece 7 to rotate, and the drive shaft 4 drives the driven gear 9 to rotate around its own axis while revolving around the sun gear through the driving gear 8, so that the driven gear 9 drives the hollow shaft 12 to rotate in the opposite direction to the drive shaft 4 through the planet carrier 11. Then, the hollow shaft 12 drives the second roller 13 to rotate in the opposite direction to the second crushing piece 7, which is conducive to further crushing. The crushed object falls onto the top of the partition plate 3 through the through holes on the outer wall of the second roller 13. When the second roller 13 rotates, it drives the third crushing blade 14 to rotate, so that the third crushing blade 14 performs a third crushing operation on the object. The crushed object is discharged through the through holes on the outer wall of the device housing 1, thus effectively realizing the multi-stage screening and crushing work and effectively improving the fineness of crushing.
