An asphalt pavement paving material mixing device

Abstract

The invention relates to the technical field of asphalt pavement paving, in particular to a mixing device for asphalt pavement paving materials, comprising a housing, a feeding mechanism, a collecting mechanism, a stirring mechanism, a first screening mechanism, a second screening mechanism and a shaking mechanism; The feeding mechanism is beneficial to prevent the material from sliding down and clogging, and the primary screening and filtering of the material is carried out through the first screening mechanism, which is beneficial to the removal of fine sand and gravel, and the screened sand and gravel are further screened under the action of the second screening mechanism The waste of resources is reduced, and the blocking of the first screening mechanism is prevented under the action of the shaking mechanism. Through the work of the second screening mechanism, the fallen sand and gravel particles are classified and dropped, and are collected under the action of the collection mechanism. Collecting and storing is convenient for subsequent use. Under the action of the stirring mechanism, it is beneficial to mix and blend the materials, which is convenient for subsequent road laying. At the same time, the stirring mechanism is conducive to providing power for the first screening mechanism to rotate.

Description

technical field [0001] The invention relates to the technical field of asphalt pavement paving, in particular to a mixing device for asphalt pavement paving materials. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metal derivatives. It is a kind of high-viscosity organic liquid. It is liquid and has a black surface. It is soluble in carbon disulfide. Asphalt is a waterproof and moisture-proof and As an anti-corrosion organic gelling material, asphalt can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch: among them, coal tar pitch is a by-product of coking, petroleum pitch is the residue after crude oil distillation, and natural pitch is stored underground. , Some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries as well as paving roads. [0003] When layin...

AI Technical Summary

Problems solved by technology

[0003] When laying asphalt pavement, it is necessary to mix stones with asphalt to lay the road surface. Before laying asphalt pavement, the mixed stones need to be filtered, and then mixed and stirred, so as to ensure that the particles of stones are uniform, which is conducive to improving the inside quality and service life, however, the traditional work of stone screening is separated from stirring, which reduces the efficiency, and at the same time, the stones after screening are inconvenient to be further sorted and stored, so that after collection, treatment and screening It is inconvenient to operate when there are stones, time-consuming and labor-intensive
