Asphalt pavement paving material mixing device

Abstract

The invention relates to the technical field of asphalt pavement laying, in particular to an asphalt pavement laying material mixing device. The device comprises a shell, a feeding mechanism, a collecting mechanism, a stirring mechanism, a first screening mechanism, a second screening mechanism and a shaking mechanism. Materials are prevented from sliding down and being blocked through the feedingmechanism, the materials are preliminarily screened and filtered through the first screening mechanism, fine gravel is removed, the screened gravel is further screened under the action of the secondscreening mechanism, resource waste is reduced, the first screening mechanism is prevented from being blocked under the action of the shaking mechanism, and the screening efficiency is improved. Through work of the second screening mechanism, fallen gravel particles fall in a classified mode and are collected and stored under the action of the collecting mechanism, subsequent use is facilitated, mixing, stirring and blending of materials are facilitated under the action of the stirring mechanism, and subsequent pavement laying is facilitated; meanwhile, the stirring mechanism is beneficial toproviding 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
