Building sand screening device facilitating feeding

Abstract

The invention discloses a building sand screening device facilitating feeding. The building sand screening device comprises a sand screening roller, two sets of clamping rings are arranged on the sandscreening roller in bilateral symmetry and sleeving manners, a ball bearing is arranged between the inner wall faces of the clamping rings and the outer wall face of the sand screening roller, the tops of the clamping rings are connected to a connecting plate, a rotary disc is arranged in the center of the upper surface of the connecting plate, a hinge block is welded to the center of the top ofthe rotary disc, the top end of the hinge block is provided with a connecting rod through hinged connection, a top plate is arranged above the ball bearing, the upper end of the connecting rod is connected to the top plate, a feeding hopper is inserted into the front end of the top plate, the left and right sides of the ball bearing are symmetrically sleeved with two sets of side connecting rings,a fixed cabin door is installed on the side connecting ring on the right side through a bolt, a sliding cabin door is arranged on the left side of the ball bearing, and six sets of sliding columns connected to the sliding cabin door are installed on the side connecting ring on the left side in a penetrating manner.

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
