The stirring block 22 can stir the water in the screening barrel 2, so that the water has a certain impact force. The impact force of the water rotation can break up the wheat, and the impurities mixed with the wheat will also float to the surface of the water. Then the sealing plug 12 is pulled out, and the water and impurities will flow out of the water outlet 11 together. The sealing block 21 can effectively seal the rotating shaft position of the motor 19 and the telescopic shaft position of the telescopic cylinder 20, thereby avoiding water leakage in the screening barrel 2. When the wheat needs to be taken out, the user starts the telescopic cylinder 20 to lift the filter plate 6 and bring the wheat out of the water. Due to the existence of the first rotating shaft 7, the rotation of the support rod 8 is facilitated, and the second rotating shaft 9 can facilitate the rotation of the push plate 10. Pushing the push plate 10 can pile up the impurities on the water surface, which is more conducive to the cleaning of impurities in the later stage. Due to the existence of the base 15, the base 15 can increase the force-bearing area of ​​the bottom end of the leg 14, thereby effectively improving the stability of the leg 14 itself. At the same time, the wear-resistant layer is a wear-resistant coating, which can improve the anti-friction ability of the bottom end of the base 15, thereby effectively improving the service life of the base 15 itself. Due to the existence of the rubber pad 18, the rubber pad 18 has good protection and shock absorption capabilities. While sharing the force-bearing area of ​​the bottom end of the base 15, it also effectively improves the stability of the bottom end of the bracket 16, thereby effectively improving the firmness of the bottom end of the mounting plate 1. Due to the opening of the rectangular opening, the user can directly view the wheat in the water through the protective glass 26, so that the user can observe the status of wheat impurity screening at all times.
