step 2, a triangular pushing block (30) is driven to reciprocate together in the reciprocating motion process of a screening box (22), the triangular pushing block (30) moves to impact a cylindrical block (18), meanwhile, shaking of a collecting tray (12) is achieved under the cooperation of a supporting spring (14), raw materials smaller than the aperture of a filter screen fall into the collecting tray (12) when the screening box (22) screens, raw materials larger than the aperture are left in the screening box (22), and the raw materials falling into the collecting tray (12) slide along the collecting tray (12) and are discharged from a discharge outlet (11);
step 3, after the screening of the raw materials in the screening box (22) is completed, the fixing plate (7) is pushed to move upwards through the first electric cylinder (9), the fixing plate (7) pushes the supporting rod (5) to incline, the supporting rod (5) can drive the screening box (22) to incline correspondingly after inclining, meanwhile, the output end of the second electric cylinder (16) contracts to drive the sealing plate (23) to move upwards to open the discharge port (28), at the moment, the residual raw materials screened in the screening box (22) can be discharged from the discharge hopper (15) under the movement of the screening box (22), and the second electric cylinder (16) and the first electric cylinder (9) are reset after the raw materials are completely discharged;
step 4, when the screen cloth at the bottom of the screening box (22) needs to be switched, the two speed reducing motors (8) are operated to drive the scroll (29) to correspondingly rotate, so that the combined screen cloth (10) can be dragged to wind on the scroll (29), the scroll (29) at one side winds, the scroll (29) at the other side is discharged, and further the switching of the screen cloth at the bottom of the screening box (22) can be realized.
