When in use, the rotating shaft 5 drives the rotating plate 14 to rotate, and drives the square plate 16 to move up and down periodically through the connecting plate 15, so that the sieve plate 10 moves up and down periodically in the lifting hole 19. At this time, the telescopic sleeve rod 20 moves up and down accordingly to prevent the position of the sieve plate 10 from shifting during movement. When it is necessary to adjust the height of the up and down movement of the sieve plate 10, rotate the threaded rod 18 to drive the sliding block 17 to slide in the sliding groove, and adjust the height of the up and down movement of the sieve plate 10 by changing the position of the sliding block 17.

[0025] When the utility model is in use, the device is first moved to a suitable position and fixed by the Forma wheel 12, and then the soil to be crushed is placed on the conveyor belt 23.
