A scattering component is provided on the outer surface of one end of the scattering chassis; the rotation of the rotating shaft drives the rotation of the second spiral blade, and the second spiral blade drives the rotation, so that the discharge pipe is not easily blocked by the material, and the rotation of the second spiral blade facilitates faster discharge; the defect of this structure is that it adopts double rotating shafts for scattering and does not have a knocking function. Not only is the scattering effect not good, but the rotating shaft does not have a conveying function and needs to rely on the spiral blade for conveying. The structure is complicated, which increases the cost of the equipment and cannot meet the needs of actual use. Therefore, there is an urgent need for improved technology on the market to solve the above problems. Utility Model Content
