Municipal road asphalt paving device

Abstract

The invention discloses a municipal road asphalt paving device, belongs to the field of road building machines and aims at providing a paving device used for reducing the phenomenon of local asphalt mixture excessive filling during road surface paving. The technical scheme of the municipal road asphalt paving device includes that the device comprises a forwarding frame, a stirring mechanism and aflattening mechanism, wherein the stirring mechanism is arranged at the end, in the forwarding direction, of the forwarding frame, and the flattening mechanism is arranged at the end, away from the stirring mechanism, of the forwarding frame; a leaking port is formed in the middle of the forwarding frame, and a filling device is arranged in the leaking port; and the filling device comprises a conveying flattening mechanism arranged at the end close to the stirring mechanism and a push plate flattening mechanism arranged at the end close to the flattening mechanism. The municipal road asphalt paving device has the advantages that an asphalt mixture is uniformly filled flatly, and the phenomenon of local asphalt mixture excessive filling during road surface paving is reduced.

Description

technical field [0001] The invention relates to the field of road construction machinery, in particular to an asphalt laying device for municipal roads. 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, and the pavement needs to be dust-removed before asphalt pavement, otherwise it will affect the...

Problems solved by technology

[0004] Although this asphalt integrated paving machine is equipped with an adjustable connection mechanism between the tractor and the laying device, thereby reducing the deformation of the connection mechanism due to vibration; but in the actual use process, the asphalt mixture falls from the leakage port to On the paving surface, the auger with positive and negative transmission can initially fill the asphalt mixture back and forth. When the auger is working, it smooths the asphalt mixture on the straight line where the auger is located. Since the laying machine is always in motion, the auger The position of the dragon also moves with the production, which has a certain impact on the leveling of the asphalt mixture, which will cause excessive filling of the asphalt mixture locally
