[0031] Third step: Start the electric telescopic rod 20, drive the material blocking plate 21 to move away from the screening box 3 through the electric telescopic rod 20, and then make the unqualified sand material discharge through the second discharge port, the sieve plate 14 and the first discharge port through reciprocating movement.
