Hot rolling roller for asphalt road construction

Abstract

The invention discloses a hot rolling roller for asphalt road construction. The roller structurally comprises a vertical rod, a mounting frame, a fixing head and a cylinder body; the cylinder body ismechanically connected with the mounting frame through the fixing head; the mounting frame is mounted on the walking device through two vertical rods vertically fixed at the upper end; the cylinder body comprises a charging hole, a heating core, small heat dissipation holes, a discharging hole, a material collecting mechanism and a self-propelled scraper blade; the charging hole and the discharging hole are communicated with the heating core; more than two small heat dissipation holes are formed in the heating core; and a slideway matched with the self-propelled scraper blade is arranged on the heating core. According to the invention, when the cylinder body rolls, remaining materials are concentrated in the lower layer due to the gravity effect, therefore, the charging hole and the discharging hole which are distributed in an X shape in the crossed mode are formed in the heating core, no matter how the heating core rolls, one discharging port is located in the lower layer, remaining materials in the heating core are effectively discharged, the remaining materials on the inner wall of the heating core can be scraped cleanly by combining the self-propelled scraper blade in the discharging process, and the situation that combustion is affected due to mixing of newly-added materials and old materials is avoided.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a hot rolling roller for asphalt road construction. Background technique [0002] In the construction process of paving asphalt roads, asphalt floor hot rolling rollers are usually used to roll and level the road surface to achieve a certain degree of flatness. The main structure of the existing asphalt floor hot rolling rollers is a metal The hollow cylinder is used as the outer drum, and there is a closed hollow semi-cylindrical inner heating core inside the outer drum. There are many heat dissipation holes on the inner heating core, and a shaft is welded at both ends of the inner heating core and passes through it. Due to the effect of the center of gravity on the central hole of the end cover of the outer drum and the outside of the push handle, the opening of the heating core is always upward. During construction, the burning charcoal is first placed in the inner h...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a hot rolling roller for asphalt road construction, which is used to solve the problem that the burnt charcoal in the heating core needs to be stopped for cleaning along with the construction of the hot rolling roller. During this process, it cannot Realize the continuous operation of the hot rolling drum, and the internal temperature of the hot rolling drum is high. At this time, the safety factor of replacing charcoal is not only low, but also the carbon ash is easy to volatilize into the environment, causing technical problems of environmental pollution
