After the crushing operation is completed, the sealing cover plate 400 is rotated, and the crushed corn stalks are taken out. When the sealing cover plate 400 is in an open state, cleaning liquid is introduced into the crushing bin 100. At this time, the servo motor 200 is started, and the rotating disc 502 drivingly connected with the servo motor 200 is rotated. The rotating disc 502 is fixedly connected with an extrusion plate 503 on the outside, the side surface of the hydraulic bin 501 is slidingly connected with a stress rod 504, the side surface of the stress rod 504 is fixedly connected with a spring 505, one end of the spring 505 away from the stress rod 504 is located in the inside of the hydraulic bin 501, and the spring 505 and the inner wall of the hydraulic bin 501 are in a fixed connection state. When the rotating disc 502 rotates, the rotating disc 502 drives the extrusion plate 503 fixedly connected with the rotating disc 502 to rotate, and the plurality of extrusion plates 503 intermittently extrude the stress rod 504 in sequence. Because the side surface of the stress rod 504 is fixedly connected with the spring 505, the stress rod 504 reciprocatingly moves in the hydraulic bin 501 slidingly connected with the stress rod 504. The bottom of the hydraulic bin 501 is slidingly connected with a transmission rod 506, and the bottom of the transmission rod 506 is fixedly connected with a brush plate 507. When the stress rod 504 reciprocatingly moves in the hydraulic bin 501, the transmission rod 506 slidingly connected with the hydraulic bin 501 is driven to reciprocate, so that the transmission rod 506 drives the brush plate 507 fixedly connected with the transmission rod 506 to reciprocate on the inner wall of the crushing bin 100.
