Sand screening device with raw material lifting function for municipal construction

Abstract

The invention discloses a sand screening device with a raw material lifting function for municipal construction. The sand screening device comprises a base, wherein a supporting plate is fixedly arranged at the top of the base through supporting legs, the supporting plate is inclined towards the right lower part, a left vertical plate and a right vertical plate are correspondingly and fixedly arranged on the left side and the right side of the top of the supporting plate, a roller is arranged between the left vertical plate and the right vertical plate, and baffles are fixedly arranged on theleft side and the right side in the roller correspondingly; and a plurality of material passing ports are uniformly formed in the circumferential direction of a joint between each baffle and the innerwall of the roller, a plurality of rectangular ports are formed in the side wall of the roller, and the rectangular ports are fixedly connected with arc-shaped screens, and a rectangular port matchedwith the roller is formed in the supporting plate. According to the sand screening device, a lifting device is arranged to drive sand to move upwards to carry out automatic feeding, so that the sandscreening device is more convenient to use; the sand is driven to move through rotation of the roller, so that sand screening is carried out, and the screening efficiency is high; and the arc-shaped screens are flapped through rotation of a rubber belt, so that the sand is prevented from blocking screen holes.

Description

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

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.
