Lay on the first sieve plate 25 to avoid sand accumulation and affect the screening efficiency. At the same time, the brush 7 continuously brushes the second sieve plate 27 to avoid the blockage of the round holes of the second sieve plate 27, which further improves the screening efficiency. At the same time, the electric heating element Work 17 dries the sand, and the screened sand falls into a collection frame 2 under the cooperation of the inclined plate 28 and the movable plate 29. After filtering out sand with a particle size, the second sieve is adjusted by an electric push rod. The position of the plate 27, and then adjust the size of the sieve hole, and turn the handle 4, so that the movable plate 29 rotates a certain angle, so that the sand outlet is connected with another collection frame 2, and then the sand of another particle size is screened out. Sands of different particle sizes can be screened out, which improves the screening efficiency.
