Description

Technical Field

[0001] The utility model relates to the technical field of road asphalt rolling, in particular to a road asphalt rolling device. Background Art

[0002] After searching, it was found that the Chinese patent publication number CN219752899U disclosed "A kind of powder and fine sand layer asphalt road rolling device", which includes an asphalt roller and a cleaning cover plate. The front and rear ends of the asphalt roller are both provided with asphalt rollers, and the lower ends of the asphalt rollers are both provided with rolling wheels, and the rolling wheels are transmission-connected with the asphalt rollers, and the upper ends of the rolling wheels are provided with a cleaning cover plate; the utility model, through the arrangement of the cleaning cover plate and the cleaning scraper, passes the asphalt oil from the oil pipe joint into the pressure pump inside the connecting chamber, the pressure pump pressurizes the asphalt oil and injects it into the oil pipe, and the electric heating outer pipe outside the oil pipe heats the asphalt oil, so that the asphalt The oil is not easy to condense. After that, the asphalt oil is injected into the atomizing nozzle plate from the pressure nozzle under pressure and then sprayed out. The atomizing nozzle plate sprays the asphalt oil into atomized form, which greatly improves the thermal melting efficiency of the asphalt on the surface of the rolling wheel, so that the asphalt particles attached to the surface of the rolling wheel can be easily scraped off and removed by the cleaning scraper, solving the problem of the existing asphalt road rolling device that the rolling wheel hub surface is easy to adhere to asphalt, resulting in uneven rolling roads and inconvenient cleaning. Through the setting of the hydraulic rod and the roller fixing bolt hole, the hydraulic rod controls the degree of fit between the cleaning scraper at the lower end of the cleaning cover and the rolling wheel, and the roller fixing bolt hole facilitates the hanging and fixed installation of the cleaning cover;

[0003] The pressurized nozzle cleans the surface by increasing the pressure of the water flow, but for a sticky substance like asphalt, a simple water flow may not be enough to completely remove it, especially when the asphalt has cooled and hardened. The design and use of the nozzle may also affect its cleaning effect. For example, if the design of the nozzle cannot ensure that the cleaning agent is sprayed evenly and fully onto the surface of the roller, then even if an effective cleaning agent is used, the expected cleaning effect may not be achieved.
