The invention discloses a simple and efficient sand-stone screening device. The simple and efficient sand-stone screening device comprises a feeding pipe, a grid, a liquid level meter, a box, a waterinlet pipe, a flowmeter, a spraying head, a rotating shaft, a camera, a timer, an impeller, a screening plate, a vibration exciter, a coarse sand discharging pipe and a fine sand discharging pipe. Thetop end of the box is provided with the feeding pipe. The grid is obliquely arranged in the feeding pipe. The lowest end of the grid is provided with an impurity discharging pipe. The box is providedwith the liquid level meter. The box communicates with the water inlet pipe. The outlet end of the water inlet pipe is provided with the spraying head. The flowmeter is mounted on the water inlet pipe. The camera is arranged on the inner wall of the top end of the box. The box is internally provided with the rotating shaft. The impeller is mounted on the rotating shaft. The screening plate is obliquely arranged in the box. The lower surface of the screening plate is provided with the vibration exciter. The screening plate comprises a first screening plate body and a second screening plate body. According to the simple and efficient sand-stone screening device, sand-stone is screened, the working efficiency is improved, both time and labor are saved, the structure is simple, using is convenient, and popularization is facilitated.
