Crushing and sand screening device for building construction

Abstract

The invention discloses a sand crushing and screening device for building construction, comprising a support installation module, an auxiliary swing module and a rolling screening module. The support installation module includes a bottom installation plate, and the upper right end of the bottom installation plate is provided with a swing installation plate. The rolling screening module is arranged above the bottom mounting plate between the swing motor and the swing mounting plate, the rolling screening module includes a rolling screening mechanism and a rolling transmission mechanism, the rolling screening mechanism includes a screening drum, and the screening drum includes two ends symmetrical The roller mounting plate is provided, and the auxiliary swinging module is arranged above the bottom mounting plate, and the auxiliary swinging module includes a swinging motor fixed on the bottom mounting plate arranged under the swing mounting plate on the left side. The present invention has good screening tolerance, There are obvious improvements and advantages such as high utilization rate of building materials, efficient and stable structural transmission, high sand screening efficiency, time-saving and labor-saving.

Description

technical field [0001] The invention relates to building construction equipment, in particular to a crushing and sand screening device for building construction. Background technique [0002] The sand sieving machine imitates the working principle of artificially using the inclined screen to screen sand. It adopts a flat rolling screen cylinder and ensures that the material flow can be continuously rolled for more than five circles between the multi-turn inner spiral blades in the screen cylinder, so that the sand material can be repeatedly screened. It is fully discrete and separated by tumbling and sliding; it is different from the pushing and burying of large and small materials caused by inclined roller sieves, and the screening process is rushed; it is also different from the vibration and mixing of large and small materials caused by inclined vibrating screens. [0003] Due to the imperfect design of the traditional sand screening device for building construction, the ...

Problems solved by technology

[0003] Due to the imperfect design of the traditional sand screening device for building construction, the sand screening tolerance is poor, the treatment effect on sand with many debris is poor, the processing efficiency is low, and the transmission efficiency is low. damage headlight problem

[0004] In order to solve the above problems, the present invention is proposed, which overcomes the traditional sand screening device for building construction. Since the sand and stones that are agglomerated are not treated when screening sand and stones, and the sand and stones mixed with soil are not distinguished, the sand and stones that are screened The utilization rate of stone is low, and due to the existence of these large-sized debris, the screening efficiency is low, and the working surface needs to be cleaned frequently, resulting in time-consuming and laborious sand screening process, and in serious cases, the construction period will be delayed and the problem of heavy losses will be solved. The traditional sand screening device for building construction has a slow sand screening speed and poor sand screening effect. Through the ingenious fusion of the auxiliary swing module and the rolling screening module, the present invention has good screening tolerance, high utilization rate of building materials, and efficient structural transmission. Stable, high sand screening efficiency, saving time and labor and other obvious improvements and advantages
