The rotation of the damping shaft 14 drives the cylinder 15 to rotate. Since the cylinder 15 has a receiving port 16, after the storage box 10 is filled with corn seeds, the corn seeds will enter the receiving port 16. As the cylinder 15 rotates, the receiving port 16 rotates downward, so that the corn seeds fall into the trough body of the discharge hopper 17, and then enter the discharge pipe 18 through the feeding cavity, and finally are discharged through the first hollow tube 1, so that the corn seeds can fall accurately into the pit for sowing and material dropping, which greatly reduces the burden on the farmer's waist, effectively prevents the discomfort caused by long-term bending work, protects the farmer's health, and also solves the problem that traditional sowing equipment is difficult to control the sowing and feeding amount.
