The outer surface of the second stroke column 463 presses against the inner wall of the stroke ring 462 and slides along the inner wall of the stroke ring 462, so that the stroke ring 462 drives the first stroke column 452 to move up and down through the pusher 461. The outer surface of the first stroke column 452 presses against the inner wall of the first stroke groove 451, so that the rotating rod 430 rotates up and down around the support member 440 as the rotation center. The rotating rod 430 then drives the striking plate 410 to move together through the connecting rod 420. Then, the second motor 703 is started, and the second motor 703 drives the threaded rod 702 to rotate. The threaded rod 702 drives the transmission block 701 to move back and forth through the thread. The transmission block 701 then indirectly drives the striking plate 410 to move back and forth, so that the striking plate 410 quickly hits the surface of the screening mechanism 3 and knocks the stones stuck on the surface of the screening mechanism 3 off.
