Sand sorting and screening device for building construction

Abstract

The invention discloses a sand sorting and screening device for building construction, and relates to the technical field of building equipment. The device includes a tank body, a sand inlet incline channel is fixedly connected with the top of the tank body, a sliding groove is formed in an inner side face of the tank body, a plurality of arc-shaped rotating board is connected with the inside of the sliding groove in a sliding mode, a ring-shaped sand screening screen board is fixedly connected with a side face of a support board, the inner circumferential side face of the ring-shaped sand screening screen board is attached to the outer circumferential side face of the arc-shaped rotating boards, a rotating shaft is connected with an inner side face of the tank body in a rotating mode, a fixing rod is fixedly connected with the circumferential side face of the rotating shaft, and one end of the fixing rod is fixedly connected with the inner circumferential side faces of the arc-shapedrotating boards. According to the device, through the design of the sliding groove, the arc-shaped rotating boards, the ring-shaped sand screening screen board, the rotating shaft, the fixing rod anda stop board, sand materials in the ring-shaped sand screening screen board can be rolled continuously up and down, the sand screening efficiency and the sand screening effect can be greatly improved,meanwhile the situation that sand materials are attached into the ring-shaped sand screening screen board so that the cleaning difficulty is increased can be efficiently prevented.

Description

technical field [0001] The invention belongs to the technical field of construction equipment, in particular to a sorting and sand screening device for building construction. Background technique [0002] Concrete is a commonly used building material in the process of building construction. It mainly uses cement as the cementitious material, mixed with water, sand, and stones, and if necessary, chemical admixtures and mineral admixtures are mixed in an appropriate proportion. After uniform mixing, Artificial stone made of dense molding and hardening. When using sand, there are more large-grained stones in the natural sand, so it must be screened before use to remove the larger particles in the sand. , Some small sand screening devices are commonly used on the construction site to screen coarse sand. [0003] At present, the sand screening device is usually an inclined screen. Workers spread sand on the inclined screen. The fine sand falls through the screen through its own ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a sorting and sand screening device for building construction. Through the design of chute, arc-shaped rotating plate, annular sand screening net plate, electric telescopic rod, vibrating plate and inclined channel for sand feeding, the existing problems are solved. The current sand screening device is usually an inclined screen, which has low sand screening efficiency and poor sand screening effect, which greatly increases the labor intensity of workers.
