[0037] Each swing seat 35 is provided with a swing bearing, the swing crushing roller 33 is arranged in the crushing shell 31 and is connected to the two swing bearings, and the swing crushing roller 33 can rotate in the crushing shell 31, each fixed seat 34 is provided with a fixed bearing, the fixed crushing roller 32 is arranged in the crushing shell 31 and is connected to the two fixed bearings, and the fixed crushing roller 32 can also rotate in the crushing shell 31, the ends of the fixed crushing roller 32 and the swing crushing roller 33 are extended to the outside of the crushing shell 31 and are provided with a power receiving part, and the power transmission structure on the vehicle body 5 can drive the fixed crushing roller 32 and the swing crushing roller 33 to rotate through the fixed crushing roller 32 and the swing crushing roller 33, thereby achieving the crushing of crops.

[0038] The outer circumferential surfaces of the fixed crushing roller 32 and the swinging crushing roller 33 are both provided with crushing edges, and a crushing channel is formed between the fixed crushing roller 32 and the swinging crushing roller 33 in the crushing shell 31.
