[0031] Among them, the number of crushing components is multiple groups, and the multiple groups of crushing components are arranged up and down; in this embodiment, the crushing components are configured into two groups, and the crushing device can be divided into a primary crushing device and a secondary crushing device. The primary crushing device is located above the secondary crushing device, and the lower end of the primary crushing device is connected to the upper end of the secondary crushing device.

[0032] Specifically, the primary crushing device includes a primary housing 310, a primary gear, a roller body 311 and a primary rotating shaft. Circular holes 318 matching the primary rotating shaft are provided on both sides of the primary housing 310. A key 312 is provided on the primary rotating shaft. A key groove matching the key 312 is provided on the primary gear and the roller body 311 (not shown in the figure). The primary rotating shaft includes a primary main shaft 313 and a primary secondary shaft 314. The primary gear is arranged on the outer side of the primary housing 310. The primary gear includes a primary driving gear 315 and a primary passive gear 316. The primary driving gear 315 is externally meshed with the primary passive gear 316. When the primary gear is rotated from the side where the power device is located, the primary driving gear 315 and the primary passive gear 316 in the primary gear rotate in opposite directions. In this embodiment, the primary driving gear 315 is arranged to rotate clockwise, and the primary passive gear 316 is arranged to rotate counterclockwise.

The other end of the primary main shaft 313 and the other end of the primary secondary shaft 314 pass through the circular hole 318 on the other side of the primary housing 310 and are respectively engaged with the key slots (not shown in the figure) on the primary driving gear 315 and the primary driven gear 316 through the key 312.
