Efficient sand screening equipment for construction

Abstract

The invention relates to the technical field of building equipment, and in particular relates to efficient sand screening equipment for construction. The equipment comprises a base, wherein a shell isslidably connected to the inner side of the base, a feeding hopper is arranged at the top of the shell, a screening mechanism is arranged on the lower side of the feeding hopper, and the screening mechanism is connected with a supporting mechanism arranged on the inner side of the base through a transmission mechanism. According to the equipment, through the arrangement of the screening mechanism, a motor drives a cam to rotate through a rotating rod, a containing frame can move left right repeatedly under the action of the cam and a spring, the screening efficiency of the equipment can be improved, and through the arrangement of the transmission mechanism, the motor can enable a movable plate to move left right repeatedly while enabling the containing frame to move left right repeatedly,the movable plate enables the shell to vibrate up and down through a supporting rod, and thus the screening effect of the equipment is further improved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to high-efficiency sand screening equipment for construction. Background technique [0002] Sand has a wide range of uses. In addition to being used for construction, road construction, filtration, breeding and beautification, and as an accelerator for smelting, it is also the main material for making glass. It contains silicon, and it can be used in sports besides sand pools. Sandbags for boxing and flood control are indispensable. Sand is one of the main components of concrete and mortar. It is a bulk material for civil engineering. In the process of using sand in construction, in order to ensure the quality of buildings, The sand needs to be sifted through screening equipment when it is used. [0003] Existing manual screening of sand and machine screening, the screening speed is slow during manual screening, resulting in low efficiency and a lot of labor, while t...

AI Technical Summary

Problems solved by technology

[0003] Existing manual screening of sand and machine screening, the screening speed is slow during manual screening, resulting in low efficiency and a lot of labor, while the machine screening operation is complicated, and can only screen finished sand with a single particle diameter, which cannot be used according to the use. Therefore, in view of the above situation, it is urgent to develop a high-efficiency screening equipment for construction sand to overcome the shortcomings in current practical applications.
