Soil screening device

The utility model relates to the technical field of geological detection, and discloses a soil screening device which comprises a box body, supporting legs are connected to the bottom of the box body in a bolting mode, a soil blocking mechanism is arranged in the box body, a damping mechanism is arranged on the top of the box body, and a shell is connected to the top of the damping mechanism in a bolting mode. The motor drives the rotating block to rotate, the rotating block drives the material spreading rod to rotate, and the material spreading rod rotates to scatter soil on the surface of the screen, so that the anti-blocking purpose can be achieved, the screening efficiency is improved, the workload is reduced, and use is convenient; the rotating rod rotates to enable the connecting rod to drive the clamping head to move, the clamping head moves to enable the clamping head to be separated from the limiting plate, and the limiting plate and the rotating block are taken out, so that the purpose of convenient
