Hot wind layered heating type re-stirring locomotive

Abstract

The invention belongs to the technical field of highway engineering machines and in particular relates to a hot wind layered heating type re-stirring locomotive. The hot wind layered heating type re-stirring locomotive comprises a stander supported by bearing wheels, wherein a new material receiving hopper is arranged at the front end of the stander; a scraper blade lifting device and a stirring jar are arranged on the stander; a weighing measuring hopper is arranged at the upper end of the scraper blade lifting device; a feeding opening of the stirring jar is positioned below the weighing measuring hopper; a hot material vertical lifting device and a hot wind circulation heating device are arranged in the middle of the stander; the upper part of the vertical lifting device is provided with a discharge opening; the lower part of the hot wind circulation heating device is provided with a conveying plate chain; and the discharge opening is formed towards one side of a feeding end of the surface of the conveying plate chain. By utilizing the hot wind layered heating type re-stirring locomotive, a new-old asphalt mixture can be sufficiently and uniformly heated, the material distribution is layered and uniform, the stirring temperature is sufficient and uniform finally, a new mixture with the stable temperature is obtained, and the stable quality of a new pavement is ensured.

Description

technical field [0001] The invention belongs to the technical field of road engineering machinery, and in particular relates to a hot air layered heating remixing locomotive. Background technique [0002] After long-term use of asphalt pavement, there will be defects such as ruts and depressions, which will accelerate the damage of the pavement and affect driving safety. The hot-in-place regeneration process of asphalt pavement can be summarized as follows: first, the defective asphalt pavement is heated by a preheating locomotive, and after the asphalt is heated and melted, the road surface reaches a certain temperature and softened, and then milled by a milling locomotive. The softened pavement makes the asphalt pavement change from the original compacted state to the loose piled material state under the small milling force. Because the old asphalt mixture produced by milling has not changed its gradation, it is still possible to reheat the mixed asphalt mixture while add...

Problems solved by technology

This requires the heating device to provide a large amount of heating power and lengthen the heating device, resulting in extremely poor maneuverability of the remixing locomotive, which in turn affects construction efficiency and quality

Simply put, after the old and new asphalt mixtures are mixed, they cannot reach a good temperature before mixing, and temperature segregation occurs, and the temperature is not uniform enough, which will eventually affect the quality of the newly paved road surface.
