[0002] Agricultural crushing devices are used to help farmers crush crop plant stalks, mainly for crushing materials such as crop straws, grains, and feeds. Their main functions include crushing large pieces of materials into smaller particles and separating particles of different particle sizes to improve the crushing efficiency and material utilization rate.

[0003] After retrieval, a kind of agricultural crushing device with the publication number CN220991152U belongs to the technical field of agricultural devices, which includes a box body. An activity hole is opened on the surface of the box body. An activity plate is arranged in the activity hole. A delivery pump is fixedly connected to the surface of the activity plate through a support frame. A first connecting pipe is fixedly connected to the surface of the delivery pump. One end of the first connecting pipe penetrates through the surface of the activity plate. By setting the delivery pump, when people need to convey the crushed materials, people only need to control the delivery pump to work through an external control switch, and then the crushed materials in the box body can be transferred to a suitable position through a suction cup, a first connecting pipe, and a second connecting pipe, so as to convey the crushed materials. Under the action of the delivery pump, people can convey the crushed materials more quickly, and at the same time, it is convenient for people to bag and collect the crushed materials.

[0004] Based on the above patent, by means of the delivery pump, when people need to convey the crushed materials, people only need to control the delivery pump to work through an external control switch, and then the crushed materials in the box body can be transferred to a suitable position through a suction cup, a first connecting pipe, and a second connecting pipe, so as to convey the crushed materials.
