Description

Technical Field

Background Art

[0002] Peanut shelling machine is an important equipment in agricultural mechanized production. Its main task is to peel the shell of peanuts for subsequent processing or consumption. The existing peanut shelling machine usually puts peanuts into the machine manually. The peanuts first fall into the coarse grid. The peanut shells are peeled off by the rotation of the grid plate and the rubbing force between the fixed grid bars and the concave plates. Subsequently, the peanut kernels and shells fall through the grid at the same time and pass through the air duct, and most of the peanut shells are blown out of the machine by wind. However, there are many disadvantages in its use. First, during the shelling process, the peanut shelling machine has a high crushing rate due to the relatively hard overall material of the machine and rubbing back and forth on the surface of the peanuts. Secondly, the existing peanut shelling machine is easy to get stuck in the gap of the shelling net during the shelling process, resulting in blockage and affecting the shelling efficiency. Finally, in the process of separating peanut shells and peanuts, the existing equipment directly uses wind power to blow out the peanut shells and dust, resulting in the generation of a large amount of dust around the equipment, posing a potential threat to the health of the staff. In addition, the peanuts are not filtered for the second time during the separation process, and the separation effect is poor, and there are more peanut shells in the peanuts.
