The guide rails are arc-shaped, and the connection holes are located at the center of the arc-shaped guide rails Position, the material box is placed on the bottom plate, located in the middle of the two support plates, directly below the sieve.

The beneficial effect of adopting the above technical solution is that the support plate realizes the supporting function, the guide rail restricts the movement position of the sieve, and the material box realizes the storage of sand.

The sieve includes a guide rod, a rotating hole, a connecting plate, and a screen mesh. There are two guide rods, which are fixedly installed at one end on both sides of the sieve. The two guide rods are respectively fitted with two guide rails on the support plate There are two connecting plates, which are fixedly installed on the central axis positions on both sides of the sieve. There are two rotating holes, which are respectively located on the connecting plates. The screen is fixedly installed on the bottom of the sieve. The connecting hole and the turning hole are matched for installation.

The beneficial effect of adopting the above technical solution is that the guide rail constrains the moving direction of the guide rod, the rotating shaft supports the sieve through the connecting plate, and the sieve realizes the screening of sand.

The motor includes a motor body, a flywheel, and a connecting shaft. The motor body is fixedly installed on the base plate and is located next to the guide rail of the support plate. The flywheel is installed in cooperation with the motor body, and the connecting shaft is fixedly installed on the edge of the flywheel. The connecting shaft is connected with the guide rod through the connecting rod.

The beneficial effect of adopting the above technical solution is that the motor converts the rotation of the motor into the reciprocating motion of the guide rod through the flywheel, the connecting shaft and the connecting rod.
