When working, the device body 1 drives the driving shaft 21 to rotate, and the driving shaft 21 drives the first rotating disk 22 to rotate. The first rotating disk 22 and the second rotating disk 28 are connected together through the connecting column 26. When the connecting column 26 rotates with the first rotating disk 22, it will abut against the inner wall of the movable groove 25 and push the swing rod 24 to rotate. The swing rod 24 is located between the first rotating disk 22 and the second rotating disk 28 and does not contact the first rotating disk 2 2 and the second rotating disk 28 to avoid friction with the swing rod 24 when the first rotating disk 22 and the second rotating disk 28 rotate.

Similarly, when the knife rod 29 rotates to the right, the first brush 44 located on the left side of the knife rod 29 will move forward to prevent the first brush 44 and the second brush 49 from hindering the movement of the scraper during the cleaning process. During operation, the first brush 44 and the second brush 49 are close to the bearing shell body 61 but do not contact the bearing shell body 61.

During operation, the bottom end of the clamping block 54 is threadedly connected to the threaded rod 57.
