Sand sieving device for building construction

Abstract

The invention discloses a sand screening device for building construction, which includes a feed box. The sand screening device for building construction has a simple structure and stable operation. The second gear motor drives the screen material cylinder to rotate to perform coarse screening of sand and gravel. Layered screening, the sieve plate rotates and lifts to carry out secondary screening of the gravel to improve the screening efficiency and quality of the gravel. The feeding hopper and slag discharge plate can be turned and adjusted to facilitate the discharge of coarse slag on the upper side and inner side of the sieve material cylinder. The outer pipe and the inner pipe are driven to rotate by the first reduction motor, so that the sieve plate rotates in the sliding seat with the inner pipe, and the sand falling from the blanking plate is evenly distributed on the sieve plate under the action of centrifugal force, and cooperates with the sieve plate The movement in the vertical direction makes the gravel quickly pass through the sieve plate, which improves the efficiency of sand screening. The separation of coarse sand and fine sand is realized through the partition plate, which is more convenient to use, simple in structure, high in sand screening efficiency, and reduces the labor intensity of workers. , more convenient to use.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a sand screening device for building construction. Background technique [0002] Gravel is a kind of building material commonly used in construction. Generally, construction workers need to screen the sand pile through a sand screening device in order to select gravel of different sizes and use suitable gravel for construction. Traditional sand drying devices generally It consists of a mesh door panel and a door panel bracket. Workers support the mesh door panel through the door panel bracket, and use shovels to throw sand to the mesh door panel. The sand hits the mesh door panel and is filtered, so as to obtain gravel materials suitable for construction. However, this sand screening method is not only labor-intensive, but also has low sand screening efficiency, which reduces the construction progress and is very inconvenient to use.
