The automatic high-precision sand screening device for the synthetic production of building materials drives the output shaft to rotate through the driving device, the output shaft drives the cam to squeeze the screening plate intermittently, the screening plate drives the sliding rod down, and the sliding rod compresses The gas in the sleeve enters the air bag through the second one-way valve. When the screening plate is reset under the action of the second spring, due to the inertia of the screening plate, the screening plate hits the pendulum, and the pendulum drives the U-shaped rod to vibrate. The coil on the rod cuts the magnetic field line to generate current, and the generated current passes through the coil at the lower end of the coil to form a magnetic field. Since the current in the coil is alternating current, the magnetic field is formed to push the magnetic block to reciprocate in the sliding slot, and the gas in the air bag passes through the through hole. In addition, due to the vibration of the screening plate, the air jet device squeezes the third spring to move upward, and the air jet leaks out and blows the large particles of sand crushed by the cam, so that it is screened out from the sand leakage hole on the outer periphery of the screening plate.
