The frame includes a feeding cover and a discharge cover that are fixedly communicated. A bale breaking rotary knife assembly and a conveyor are arranged in the feeding cover. The bale breaking rotary knife assembly includes a secondary shaft and a main shaft arranged up and down. The secondary shaft and the main shaft are both rotatably connected between two side walls of the feeding cover, and the secondary shaft and the main shaft are in transmission connection. A plurality of first cutter discs and a plurality of second cutter discs are vertically installed on both the secondary shaft and the main shaft, and the diameter of the first cutter disc is larger than that of the second cutter disc. The plurality of first cutter discs and the plurality of second cutter discs are arranged in parallel and alternately. A motor cavity is arranged at the bottom of the feeding cover, and a servo motor and a stepping motor are arranged in the motor cavity.

The crushed forage is discharged into the discharge cover, and workers can use tools such as rakes to take out the forage. For the forage that remains on the pushing plate and is not easy to discharge, the hydraulic cylinder can be controlled to stretch the piston rod to drive the pushing plate to turn over, so as to push the forage above outwards, facilitating the workers to take out the remaining forage.
[0018] The beneficial effects of the present utility model are as follows: through the bale-breaking rotary cutter assembly, not only can high-density bales be broken, but also they can be roughly crushed, providing convenience for subsequent processing; through the frame, the pushing plate, the hydraulic cylinder and the partition plate, the forage remaining in the discharge cover can be discharged, facilitating discharging.
