Technical Field

[0001] This utility model relates to the field of asphalt paving technology, specifically to an adjustable asphalt paving leveler. Background Technology

[0002] Asphalt paving is a crucial step in road construction, directly affecting the smoothness, durability, driving comfort, and safety of the road surface. The paved asphalt layer can evenly cover the base layer, providing a smooth road surface, reducing vehicle bumps, and improving driving comfort. Therefore, a leveling tool is needed to level the ground during the asphalt paving process.

[0003] The existing patent publication number CN222043800U discloses an asphalt paving device, which includes a mixing shaft and a mixing drum. According to the required thickness of asphalt to be paved, the rotating turntable drives the second threaded rod to rotate. The rotation of the second threaded rod adjusts the scraper plate to the corresponding height. Then, the electric cylinder adjusts the pressure plate to the corresponding height. As the construction vehicle moves at a uniform speed, the scraper plate on the truck bed can scrape the asphalt discharged from the discharge pipe, and then the pressure plate will press the scraped asphalt flat.

[0004] In the above-mentioned device, when paving asphalt, a discharge pipe is used for paving, and then a scraper is used to scrape the asphalt vertically to level it. Due to the high viscosity of asphalt, it may be difficult to push the vertical scraper, which can easily lead to uneven paving. In order to address the above problems, an adjustable asphalt paving and leveling device is proposed. Utility Model Content
