[0035] Refer to Figure 2 and Figure 6, a vibration mechanism 3 is provided on the surface of the rotating rod 202. The vibration mechanism 3 includes a first roller 301. The inner cavity of the first roller 301 is fixedly connected to the surface of the rotating rod 202. A belt 305 is movably connected to the surface of the first roller 301. A second roller 304 is movably connected to the top of the inner cavity of the belt 305. A rotating column 303 is fixedly connected to the front side of the second roller 304. The front side of the rotating column 303 penetrates into the inner cavity of the box body 101. The back side of the rotating column 303 is movably connected to the front side of the inner cavity of the box body 101. A cam 302 is fixedly connected to the surface of the rotating column 303. The top of the cam 302 is movably connected to the bottom of the filter disc 109. By the operation of the rotating rod 202, the first roller 301 is driven to rotate. By the rotation of the first roller 301, the belt 305 is driven to rotate. Subsequently, the second roller 304 is driven to rotate. By the rotation of the second roller 304, the rotating column 303 is driven to rotate. By the rotation of the rotating column 303, the cam 302 is driven to rotate, thereby realizing the effect of vibrating the filter disc 109 and further avoiding the phenomenon that the material blocks the slots of the filter disc 109.

[0036] Working principle: First, start Servo Motor 1 (103). The rotation of Servo Motor 1 (103) drives the rotation of the rotating shaft (106). The rotation of the rotating shaft (106) drives the rotation of the turntable (107). The rotation of the turntable (107) drives the rotation of the grinding wheel (108). Subsequently, the material is ground between the bottom of the grinding wheel (108) and the filter plate (109). Then, the operator pours the material into the top of the filter plate (109) through the feed hopper (102). Subsequently, the grinding wheel (108) grinds it, and the filter plate (109) filters the sufficiently ground material. Then, the material falls onto the top of the diversion trough (112) under the action of gravity. At the same time, the ground material is discharged through the discharge pipe (104) through the diversion of the diversion trough (112). Second, start Servo Motor 2 (201). The rotation of Servo Motor 2 (201) drives the rotation of the rotating rod (202). The rotation of the rotating rod (202) drives the rotation of the gear (203). Under the meshing action, it drives the tooth frame (209) to move to the left. At the same time, the movement of the tooth frame (209) drives the slider (208) to slide in the inner cavity of the chute (113), thereby achieving the effect of supporting and guiding the moving tooth frame (209). Subsequently, the movement of the tooth frame (209) drives the fixed rod (211) to move. The movement of the fixed rod (211) drives the housing (206) to move. At the same time, the movement of the fixed rod (211) drives the connecting plate (205) to slide on the surface of the guiding column (204), thereby realizing the effect of supporting and guiding the moving housing (206) and fixed rod (211). The movement of the housing (206) drives the scraper (207) to move. As the slope of the diversion trough (112), the scraper (207) gradually moves downward, thereby achieving the effect of scraping the remaining material on the top of the diversion trough (112). At the same time, as the slope of the diversion trough (112), the scraper (207) slides in the inner cavity of the housing (206) and slides on the surface of the positioning shaft (214). The movement of the scraper (207) gradually restores the deformation of the second spring (213). At the same time, the limiting block (212) limits the moving scraper (207) to prevent the scraper (207) from falling off the inner cavity of the housing (206) during the movement. Finally, when the filter plate (109) is in the grinding state, the cam (302) is in the vertical state and is in close contact with the bottom of the filter plate (109), so that the top of the filter plate (109) is in close contact with the bottom of the grinding wheel (108). Then, when the rotating rod (202) rotates, it drives the first roller (301) to rotate. The rotation of the first roller (301) drives the rotation of the belt (305). Subsequently, it drives the second roller (304) to rotate. The rotation of the second roller (304) drives the rotation of the rotating column (303). The rotation of the rotating column (303) drives the rotation of the cam (302), thereby realizing the effect of vibrating the filter plate (109) and further avoiding the phenomenon of material clogging the slots of the filter plate (109).

Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification only illustrates the principles of the present utility model.
