Asphalt laying device used for road construction

Abstract

The invention discloses an asphalt laying device used for road construction. The asphalt laying device used for road construction comprises a bottom board, a stirring cavity, a cylinder body, a conveying cavity and a vibrating leveling board. The stirring cavity is arranged at the upper end of the bottom board, and the upper end of the left side of the stirring cavity communicates with a feeding hopper. The conveying cavity is formed in the lower end of the stirring cavity. The cylinder body is fixedly installed on the right side of the stirring cavity, a piston is arranged in the cylinder body in a sliding mode, a push rod is fixedly installed at the upper end of the piston, the upper end of the push rod penetrates through an upper cover board of the cylinder body and is hinged to a connecting rod, the connecting rod is rotationally connected to a crankshaft, and the crankshaft is fixedly connected with a first rotary shaft. The asphalt laying device is novel in design, the effect ofcontrolling the discharging amount of asphalt can be achieved through the arranged conveying cavity, so that the asphalt laying thickness is changed, different laying requirements are met, air emittedby the cylinder body is cooled by a refrigerating machine and then sprayed to the laid asphalt through a nozzle, so that asphalt cooling is quickened, following vibrating leveling treatment is facilitated, work efficiency is high, and the automation degree is high.

Description

technical field [0001] The invention relates to the field of road construction, in particular to an asphalt laying device for road construction. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is liquid, semi-solid or solid. It is a waterproof, moisture-proof and anti-corrosion organic gelling material. Used in coatings, plastics, rubber and other industries, as well as paving roads, etc. Asphalt is solid at room temperature, so it needs to be heated to melt the solid asphalt during use. The heating temperature is generally around 120°C. The asphalt in the prior art is generally heated by a boiler and then transported to the laying equipment. As a result, the temperature of the asphalt has dropped, and the quality of the paved asphalt pavement has declined. After the general paving device is laid, it needs to be cooled for a certain period of time before bein...

Problems solved by technology

Asphalt is solid at room temperature, so it needs to be heated to melt the solid asphalt during use. The heating temperature is generally around 120°C. The asphalt in the prior art is generally heated by a boiler and then transported to the laying equipment. As a result, the temperature of the asphalt has dropped, and the quality of the paved asphalt pavement has declined. After the general paving device is laid, it needs to be cooled for a certain period of time before being vibrated by other devices, which leads to low work efficiency and cannot meet the requirements of asphalt paving with different thicknesses.
