Sand screening device for building equipment

Abstract

The invention relates to the technical field of building equipment, and discloses a sand screening device for building equipment. The sand screening device comprises a bottom plate, wherein hydrauliclifting rods which are symmetrical with each other are uniformly distributed on the bottom of the bottom plate; the bottoms of the hydraulic lifting rods are fixedly equipped with circular table supporting discs; a gasket between the hydraulic lifting rods is uniformly distributed on the bottom of the bottom plate; universal wheels are fixedly mounted on the bottom of the gasket; four supporting plates which are symmetrical with each other fixedly sleeve the top of the bottom plate; the tops of the four supporting plates are fixedly connected through the bottom of a rack plate; and the back surfaces of the two supporting plates are fixedly connected with the front surfaces of the two supporting plates through the two sides of a fixed plate. According to the sand screening device for building equipment disclosed by the invention, a drive motor, a rotary rod and an extrusion wheel are matched for use, so that sand poured to the top of a sieve tray is conveniently vibrated to vibrate anddrop sand, and the problem that sand screening efficiency is affected as the sand is blocked on a screen and cannot drop is avoided.

Description
