Device and method for spreading asphalt structure

Abstract

The invention discloses a device and method for spreading an asphalt structure, and relates to the field of technical road construction machines. The device comprises a work box. The top of the work box is fixedly connected with a storage box. The front side of the work box is fixedly connected with driving cases, and the left side and the right side of the work box are both fixedly connected withdriven wheel boxes. The inside of the work box is fixedly connected with a first fixing plate and a second fixing plate in sequence from top to bottom. Piston cylinders penetrate into the first fixing plate. According to the device and method for spreading the asphalt structure, the five piston cylinders and discharging sprayers are arranged, asphalt can be divided into five parts to flow onto the ground and thus be distributed more evenly, the amount of each part of the asphalt is made basically the same by adoption of the quantitative piston cylinders, and the homogenizing effect is improved; and through the matching of a crankshaft, a sliding sleeve and a rotating rod, five push rods can be pushed to act at the same time, the asphalt is squeezed out onto the ground, operation is synchronous and the asphalt distributing effect is good.

Description

technical field [0001] The invention relates to the technical field of road construction machinery, in particular to a device and method for adjusting an asphalt structure. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid with a black surface and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. Pitch 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 asphalt is the residue after distillation of crude oil. Natural bitumen is stored underground, and 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. In civil engineer...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device and method for adjusting the asphalt structure, which solves the problem of pouring the asphalt to the ground with a pipe or bucket, and the asphalt is all piled up in one piece with a large amount and spread around. After opening, the asphalt is prone to the problem of uneven thickness distribution
