Circulatory sand screening device used for construction site

The invention discloses a circulating sand screening device for a construction site, which comprises a vibrating motor, a screen, a hydraulic cylinder and a circulating conveying device. The vibration of the vibrating motor is used to speed up the screening of the sand by the screen, and at the same time, the sand screening of the sand screen is avoided. The holes cause blockage and affect the normal use of the screen. The screen is set horizontally to fully screen the sand, and the hydraulic cylinder is used to drive the hydraulic rod to extend and then push the frame to rotate along the side hinged with the box, thus realizing the screen. The inclined setting of the screen makes the sand that does not pass through the screen fall into the collection tank under the action of gravity, which realizes the automatic cleaning of the sand that does not pass through the screen, improves the practicability of the equipment, and falls from the screen into the collection tank The sand inside further slides into the cylinder body along the slanting plate, thereby realizing the circular screening of the sand and improving the effect of sand screening.
