The inner walls of the left and right side walls below the grinding box are provided with side wall grooves. The shaft body is fixed in the left side wall groove, and the rotating screw is rotatably installed in the right side wall groove. The rotating screw is driven by the bottom motor. The left and right sides of the bottom mounting frame have integrally formed protruding parts. The protruding part on the left side is movably mounted on the shaft body fixed in the side wall groove, and the protruding part on the right side is installed in cooperation with the rotating screw.

[0007] As a preferred technical solution of the utility model, a plurality of brushes are distributed on the outer surface of the cleaning shaft, and when the cleaning shaft rotates, the brushes on the surface of the filter plate are used to clean the surface of the filter plate.

[0008] As a preferred technical solution of the utility model, the rotating transmission mechanism includes a toothed plate and a gear, a toothed plate is fixed on the bottom surface inside the rear mounting groove, the rear end of the cleaning shaft passes through the through hole opened on the rear side of the pulling frame, and a gear is fixed on the end head extending into the rear mounting groove, the gear and the toothed plate are meshed with each other, when the pulling frame is pulled, the cleaning shaft installed therein also moves to the right, during this process, relative movement occurs between the gear and the toothed plate, since the two are meshed, when relative movement occurs, the gear rotates under the meshing action, driving the cleaning shaft to rotate for cleaning.

[0009] The beneficial effects of the utility model include: the filter holes of the filter plate are cleaned regularly through the filter hole cleaning mechanism to avoid clogging of the filter holes of the filter plate after long-term use, which affects the use effect; raw materials are likely to remain on the filter plate after use; the pulling frame is pulled manually and the rotating transmission mechanism is cooperated to make the cleaning shaft in the pulling frame move along the filter plate while rotating to clean the surface of the filter plate; the cleaning is simple and is conducive to popularization and use.
