Meanwhile, since the lifting plate 7 is slidably mounted on the sidewall of the tub 1, when the second grinding roll 16 applies downward pressure to the mesh 17, the mesh 17 drives the annular plate 8 and the lifting plate 7 to move downward. Because the bracing piece 12 is equipped with the screw rod, set up in the first carousel with screw rod complex screw, so first carousel can clockwise rotate when screen cloth 17 descends to first carousel drives screen cloth 17 clockwise through first one-way bearing 15 and rotates, and because the rotatable direction of second one-way bearing 14 is opposite with the rotatable direction of first one-way bearing 15, consequently, annular plate 8 can not rotate this moment, promptly, produces relative rotation between screen cloth 17 and the annular plate 8. The slide rod 10 is slidably engaged with the guard plate 20 through the slide hole, so that the slide rod 10 is moved together when the screen 17 is rotated, that is, the rolling ball 9 moves in the clockwise direction in the oval slot 22. In the moving process of the rolling balls 9 in the elliptical groove 22, the rolling balls move from the long axis to the short axis of the elliptical groove, and the length of the long axis is greater than that of the short axis, so that the distance between the two rolling balls 9 is reduced from large to small, the distance between the two groups of scraper assemblies is reduced from large to small, and the scraper assemblies collect materials to the middle part, so that the second grinding roller 16 can accurately grind the materials. After the screen 17 loses the downward pressure that applies of second grinding roller 16, screen 17 and annular plate 8 can be at upward movement under the effect of spring to make first carousel and second carousel anticlockwise rotation under the effect of screw rod, the relative rotation takes place for the inner and outer lane of first one-way bearing 15 this moment, makes screen 17 can not rotate, and the second carousel can drive annular plate 8 anticlockwise rotation through second one-way bearing 14, makes the direction of oval groove 22 change. In the lifting process of the screen 17 and the annular plate 8, the directions of the scraper component and the elliptical groove 22 are changed, the scraper component moves next time, materials are collected to the middle part from the other direction, and in the process, the scraper rod 11 repeatedly moves relative to the screen 17, so that the bristles clean the lower surface of the screen 17, and the blockage of the materials is avoided. In the moving process of the sliding rod 10, the movable scraper 19 can move along the guide groove 21 and the sliding rail, so that a scraper component formed by the movable scraper 19 and the fixed scraper 18 can always block materials and gather the materials in the middle of the screen 17.
