Install the anti-overflow structure on the outer side of the upper end of the feed pipe 6 to facilitate preventing the powdery materials from overflowing. Since the sieve holes of the sieve plate 10 disposed inside the square sieve machine 3 decrease sequentially from top to bottom, start the telescopic cylinder 18, so that the telescopic cylinder 18 drives the connecting plate 2 to shake left and right inside the middle part of the support plate 1, thereby driving the square sieve machine 3 by the connecting plate 2 to shake, and further enabling the powdery materials on the sieve plate 10 to be screened through the sieve plate 10, which is convenient for screening the powdery materials;

Pull the disassembly plate 4 outward to separate the disassembly plate 4 on the outside of the square sieve machine 3. Then rotate the installation rod 17 to connect the installation rod 17 inside the middle of the fixed plate 16, so that the installation rod 17 slides inward in the middle of the fixed plate 16, and then the installation rod 17 is separated inside the installation block 15. Then pull the sieve plate 10 upward to drive the installation block 15 to separate inside the fixed plate 16 by the sieve plate 10, so that the sieve plate 10 is separated inside the square sieve machine 3, which is convenient for replacing and repairing the sieve plate 10.
