Description

Technical Field

In engineering geological construction, it is often necessary to use sand and gravel screening devices to screen and separate sand and gravel of different particle sizes to meet engineering needs.

[0003] For example, the utility model patent with announcement number CN216064167U discloses a sand and gravel screening device for hydrological and engineering geological construction, including a base, a material guide trough is arranged on the top of the base, a mounting seat is arranged on the right side of the top of the base, and an operation cabinet is arranged on the front side of the mounting seat, a motor is arranged on the top of the mounting seat, a driving gear is sleeved on the power end of the top of the motor, the rear side of the driving gear is meshed and connected with the rack rod, and the top of the rack rod is connected with the screening assembly. After the sand and gravel screening is completed, the counterweight rod is removed upwards, and then the baffle is pulled forward, and then the screening slot is controlled to move, so that the through hole on the screening slot is opposite to the push block, and the hydraulic telescopic rod is controlled to drive the push block to push the push plate forward, so that the sand and gravel left in the screening slot that cannot pass the screening can be pushed out, thereby effectively improving the efficiency of sand and gravel removal.
