Screening device for concrete stirring

The utility model discloses a screening device for concrete mixing, a screening assembly and a spraying assembly are arranged in a box body, and the screening assembly comprises a motor, a rotating shaft, an eccentric wheel, a screening plate and a guide rod; the motor is mounted outside the box, an output shaft of the motor extends into the box and is connected with one end of the rotating shaft, two ends of the rotating shaft are rotatably connected with the inner wall of the box, eccentric wheels are fixedly connected to the outer side wall of the rotating shaft at equal intervals, and limiting grooves are formed in the left inner wall and the right inner wall of the box. Through the screening assembly capable of vibrating, accumulation on the screening plate can be prevented, and the screening efficiency is improved. And meanwhile, the spraying assembly can spray cement adhered to stones on the sieve plate, the viscosity of the cement is reduced, so that stone adhesion is prevented, falling, cleaning and
