Small crushing device with dust falling function for municipal roads

Abstract

The invention relates to the field of municipal construction equipment, in particular to a small crushing device with a dust falling function for municipal roads. The feeding bin is communicated with the upper end of the crushing device body; the first crushing assembly is mounted in the feeding bin; the feeding hopper is communicated with the upper end of the feeding bin; the feeding hole is formed in the upper end of the feeding hopper; the guide disc is movably mounted at a position where the lower end of the feeding bin is communicated with the upper end of the crushing device body through a pin shaft; the material guide wheels are distributed in the crushing device body in an inclined linear array manner; the second crushing assembly is arranged at the lower end of the crushing device body; the discharging bin is communicated with the bottom end of the crushing device body; according to the small crushing device with the dust falling function for the municipal roads, when materials are machined, the design of the arranged first crushing assembly is improved, and the good crushing effect on the materials of different shapes can be achieved; and through cooperative use of the first crushing assembly and the second crushing assembly, secondary crushing machining of the materials can be achieved.

Description

technical field [0001] The invention relates to the field of municipal construction equipment, in particular to a small crushing device for municipal roads with a dust-reducing function. 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. All kinds of public infrastructure construction supporting urban life belong to the category of municipal engineering, such as common urban roads, bridges, subways, such as various pipelines closely related to life: rainwater, sewage, water, reclaimed water, electricity (outside the red line) Parts), telecommunications, heat and gas, as well as the construction of squares, urban greening, etc., all belong to the category of municipal engineering.

AI Technical Summary

Problems solved by technology

Most of the crushing equipment in the prior art is composed of a group of identical crushing rollers. The pair of crushing rollers are installed at the position of the feed inlet, and the diameter of the feed inlet is relatively large. The place enters the gap formed by the crushing roller; through the extrusion and shear force generated by the crushing roller, the material is crushed and processed; during the crushing process, due to the large diameter of the feed inlet, the dust generated is flying all over the sky and pollutes the environment; Moreover, after only one crushing process, secondary processing is required when some processed materials do not meet the requirements; in addition, for some special shapes such as spherical materials, when the crushing roller moves, the spherical materials need to be pressed by external force when they are turned over. tight for processing
