Novel sand screening device for constructional engineering

Abstract

The invention discloses a novel sand screening device for constructional engineering. The device comprises a sand inlet groove, a screening plate, a bottom plate and a shell, wherein the shell is arranged at the top of the bottom plate, a mounting frame is transversely arranged at the upper end of the inner wall of the shell, a mounting shaft is vertically arranged in the center of the mounting frame, a second gear is arranged in the position, on the outer side of the mounting shaft, in the mounting frame, an electric piston rod is arranged on one side of the interior of the mounting frame, asecond rack matched with the second gear is transversely arranged at the output end of the electric piston rod, the top end of the mounting shaft extends to the outer side of the mounting frame and isprovided with a striker plate, a mounting plate is fixedly connected to the position, above the striker plate, of the inner wall of the shell, and the sand inlet groove is formed in the top end of the shell. According to the device, through ingenious structural design, intermittent falling is achieved, a transverse rod and a protruding strip can be driven to stir back and forth, sand accumulationis effectively prevented, and meanwhile, sand screening can be accelerated, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a novel sand screening device for construction engineering. Background technique [0002] Sand refers to fine stone particles, or something shaped like sand. Fine sand and coarse sand are generally mixed together. In order to ensure the effect of sand use, it is generally necessary to use a screen to screen out the coarse sand with larger particles to obtain particles. More uniform and smaller fine sand, so as to ensure the construction effect of sand. Existing sand screening devices generally use manual dumping, which is prone to sand accumulation and low sand screening efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a new type of sand screening device for construction engineering, which can drive the horizontal bar and the convex strip to stir back and forth while realizing intermittent blanking, effectively ...
