[0027] The servo motor a61 drives the connecting rod 62 and the pulley 63 to rotate. The pulley 63 rotates and contacts the sieve plate 2 to push the sieve plate 2 downward. The downward movement of the sieve plate 2 drives the spring 4 to extend. After the pulley 63 is no longer in contact with the sieve plate 2, the spring 4 contracts and drives the sieve plate 2 to move upward.

[0036] The utility model, when in use:

[0037] The seeds are poured into the screening box 1 through the feed hopper, and the servo motor a61 drives the connecting rod 62 and the pulley 63 to rotate. The pulley 63 rotates and contacts the sieve plate 2 to push the sieve plate 2 to move downward. The sieve plate 2 moves downward and drives the spring 4 to extend. After the pulley 63 is no longer in contact with the sieve plate 2, the spring 4 contracts and drives the sieve plate 2 to move upward. In this way, the seeds are screened through the sieve plate 2 to screen out larger impurities in the seeds. The cone frame 14 guides the seeds that fall from the sieve plate 2. The water pump 131 draws water from the water tank 12 and discharges it into the placement box 11 through the drain pipe 133. After screening, the seeds fall into the placement box 11. The water is injected into the placement box 11 to float the fine impurities and inferior seeds in the seeds and discharge them into the waste collection box a9 through the waste outlet b8. The servo motor b161 drives the stirring paddle 162 to rotate slowly to stir the accumulated seeds, thereby floating the fine impurities and inferior seeds in the seeds, and slowly stirs the seeds to clean them.
