A sand screening device for construction with convenient material loading

Abstract

The invention discloses a sand screening device for construction which is convenient for loading materials. Ball bearings are arranged between the walls, and the tops of the clamping rings are all connected to the connecting plate, and a turntable is arranged in the center of the upper surface of the connecting plate, and a hinge block is welded in the center of the top of the turntable, and the top of the hinge block is connected by a hinge. A connecting rod, a top plate is arranged above the ball bearing, and the upper end of the connecting rod is connected to the top plate, a feeding funnel is arranged on the front end of the top plate, and two sets of side connecting rings are arranged symmetrically on the left and right sides of the ball bearing, And the side connecting ring on the right side is equipped with a fixed door through bolts, the ball bearing is provided with a sliding door on the left side, and the side connecting ring on the left side is inserted with six sets of sliding columns connected to the sliding door .

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a sand screening device for construction which is convenient for loading materials. Background technique [0002] In the construction industry, sand is one of the main building materials. However, the raw materials of sand are relatively rough, and generally need to be filtered before use. Due to the relatively large amount of sand used in construction sites, sand screening devices are widely used in construction sites. Existing sand screening machines are generally divided into drum type sand screening machines, washing drum type sand screening machines and vibrating screen sand screening machines. [0003] Most of the existing drum-type sand screening machines use sand to be poured into the drum, and the sand is gradually leaked from the mesh on the surface of the drum for screening through the rotation of the drum. It is easy to make coarse sand leak from bo...

Problems solved by technology

[0003] Most of the existing drum-type sand screening machines use sand to be poured into the drum, and the sand is gradually leaked from the mesh on the surface of the drum for screening through the rotation of the drum. It is easy to make coarse sand leak from both sides, if the sand blocking cover is added on both sides, it is not conducive to the rapid loading and unloading of the inside of the drum
