[0016] 1. The screening plate and the screening barrel are arranged to slide relative to each other, and the barrel door is rotated to keep it open. At the same time, the seeds are poured into the screening barrel. At this time, the first motor drives the support plate to rotate, so that the support plate drives the support rod to push the screening plate to slide back and forth along the connecting block inside the screening barrel. At this time, the screening plate intercepts the impurities in the seeds on the upper surface of the screening plate, thereby completing the screening and filtering of the seeds;

[0017] 2. The universal wheel and the first guide rod are relatively slidably arranged, and the device is displaced to the specified position along the universal wheel by pushing the push rod. At the same time, because the farmland ground is uneven, the universal wheel slides up and down along the first guide rod at the lower end of the mounting plate. At this time, the universal wheel squeezes the spring to compress and rebound to provide a buffer space, thereby completing the shock absorption protection work of the device;

[0018] Furthermore, the second motor drives the connecting rod to rotate inside the mounting plate, and the connecting rod pushes the supporting column to move toward the lower end along the second guide rod, so that the soil-breaking block can reclaim and loosen the farmland soil. At this time, the seeds fall into the gullies reclaimed by the soil-breaking block through the sowing port, thereby completing the seed sowing work. BRIEF DESCRIPTION OF THE DRAWINGS
