A municipal road asphalt laying device

Abstract

The invention discloses a road asphalt laying device for municipal use. The road asphalt laying device comprises a traction bracket, a bottom plate, a dust suction device, a stirring cavity, a cylinder body, a trowelling plate, a vibrating tamper and a ramming wheel, wherein the dust suction device is arranged on the bottom plate; the cylinder body is arranged at the right side of the dust suctiondevice; the stirring cavity is formed in the upper end of the cylinder body; a feed hopper is mounted at the upper end of the stirring cavity; a first motor is arranged at the right side of the feedhopper; the output end of the first motor is fixedly connected with a first rotating shaft; the lower end of the stirring cavity is connected with and communicates with the cylinder body through a liquid guide pipe; the lower end of a rotating shaft is fixedly connected with a blade; a refrigerating device is arranged at the lower end of the blade; the left side of the cylinder body is connected with a discharge pipe; the vibrating tamper is also arranged at the lower end of the bottom plate; a trowelling wheel and the ramming wheel are mounted at the lower end of an upright rod of an L-shapedrod. The road asphalt laying device disclosed by the invention has dust removal and cooling functions, is high in working efficiency and good in laying effect, can meet laying requirements of different thicknesses, and has a wide range of application.

Description

technical field [0001] The invention relates to the municipal field, in particular to a municipal road asphalt laying device. Background technique [0002] Municipal roads are divided into four categories: expressways, trunk roads, secondary trunk roads and branch roads. The expressway is set up in a megacity or a large city. It uses a central divider to separate the on and off vehicles. It is a dedicated express road for automobiles. It mainly connects the main areas of the urban area, the urban area and the main suburbs, satellite towns and cities. It connects with the main external outlets, bears the main passenger and freight traffic in the city, and has a relatively high speed and a large traffic capacity. Some municipal roads need to be paved with asphalt to facilitate vehicle traffic. [0003] 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 ...

AI Technical Summary

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, and the pavement needs to be dust-removed before asphalt pavement, otherwise it will affect the quality of the asphalt pavement. The general paving device does not have this function, and the work efficiency is low. The paving effect is poor, and it cannot meet the requirements of asphalt paving with different thicknesses
