Through the arrangement of the fine sieve plate 8 and the coarse sieve plate 11, impurities and sand grains of different thicknesses can be effectively screened, so as to meet the requirements of building projects for sand grains of different thicknesses, thereby improving the use efficiency of the device. A second guide plate 12 is fixed to one side of the coarse sieve plate 11. A bearing frame 13 is installed below the inner side of the side plate 5. A first motor 14 is installed on one side of the bearing frame 13. A runner 15 is installed at the output end on one side of the first motor 14. A conveyor belt 16 is sleeved outside the runner 15. The runner 15 forms a rotating structure with the bearing frame 13 through the first motor 14. The central axis of the first motor 14 coincides with the central axis of the runner 15.
