The material will be pushed by the spiral blade 212 under the rotation of the conveying shaft 211, and conveyed to the discharge pipe 215, and finally fall to the position of the two-stage pushing mechanism 300 through the discharge pipe 215, which is convenient for subsequent separation. By adopting the spiral pushing method, it can ensure that the herbicide material with a high solid content can smoothly enter the centrifuge, reducing the problem of feed blockage.
