Anti-clogging sand screening and crushing device for municipal construction

Abstract

The invention discloses an anti-clogging sand screening and crushing device for municipal construction. The device comprises a base, wherein a supporting plate is fixedly arranged at the top of the base through supporting legs; a left vertical plate and a right vertical plate are fixedly arranged on the left side and the right side of the top of the supporting plate respectively; a roller is arranged between the left vertical plate and the right vertical plate; baffles are fixedly arranged on the left side and the right side in the roller respectively; a plurality of rectangular openings are formed in the side wall of the roller; the rectangular openings are fixedly connected with arc-shaped screen meshes; a crushing box is fixedly arranged at the right side of the top of the base througha support; the inner side wall of the crushing box is fixedly connected with a crushing cylinder; a third reduction motor is fixedly arranged at the center of the top of the crushing box; a motor shaft at the bottom end of the third reduction motor penetrates through the top wall of the crushing box and is fixedly connected with a zigzag shaft; and the zigzag shaft is rotatably connected with a crushing roller through a bearing. According to the device, the crushing cylinder is arranged in the crushing box, the crushing roller moves along the circumferential direction of the inner wall of thecrushing cylinder to crush sand with larger particles, sand is recycled, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of municipal construction machinery, in particular to an anti-clogging sand screening and crushing device for municipal construction. Background technique [0002] In my country, municipal facilities refer to various buildings, structures, equipment, etc., which are set up within the planning and construction scope of urban areas and towns (townships) and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. Various public infrastructure constructions supporting urban life belong to the category of municipal engineering, such as common urban roads, bridges, subways, such as the construction of various pipelines closely related to life, urban greening, etc., all belong to the category of municipal engineering. Sand is a kind of raw material often used in municipal construction. Sand often contains a lot of impurities such as gravel and clods. ...

AI Technical Summary

Problems solved by technology

[0003] Many construction units use artificial sand screening, which has a large workload, low efficiency, and high labor intensity; in order to improve work efficiency, some construction units use screening machines for sand screening. Although ordinary sand screening machines can increase the speed of sand screening, the sand screening The efficiency is still not high. The feed port of the sand screening machine is generally high, and the feeding is troublesome. The screen mesh is easy to block during the sand screening process, which affects the sand screening effect; after screening, the sand with larger particles is often discarded, resulting in a waste of resources.
