Technical Field

[0001] This utility model relates to the field of road construction equipment technology, specifically a road surface leveling device for highway construction. Background Technology

[0002] In the field of highway construction, road surface leveling is a crucial step in ensuring project quality. Traditional highway road surface leveling operations mainly rely on manual operation or simple mechanical equipment, which has many drawbacks. Manual leveling is not only inefficient and unable to meet the schedule requirements of large-scale highway construction, but also prone to problems such as inconsistent road surface flatness, local bumps or depressions due to the limitations of the operator's skill level and physical strength, resulting in inconsistent road surface quality. In the secondary treatment stage, traditional construction methods also face significant challenges. The spraying of concrete hardener usually relies on manual hand-held equipment, which is not only labor-intensive, but also difficult to ensure the uniformity and quantitative control of the spraying, which directly affects the concrete setting effect and the strength of the road surface. In addition, for the treatment of minor defects on the road surface, traditional manual operation is not only inefficient, but also difficult to achieve a high degree of precision, failing to meet the high standards of road surface flatness and smoothness required by modern highway construction. To solve the above problems, we propose a road surface leveling device for highway construction. Utility Model Content

After the second motor 19 is started, it drives the gears 20 to rotate through the rotating rod. The gears 20 mesh with the arc-shaped racks 21, thereby realizing the lifting or storage action of the secondary processing device 5. This storage device 4 is designed to make it convenient to store the secondary processing device 5 when it is not in use, so as to avoid damage to the device from collisions. At the same time, it can be quickly and conveniently adjusted to the working position when needed, which improves the practicality and ease of operation of the device.

[0027] Furthermore, multiple sets of coagulant nozzles 22 are fixedly installed in the middle of the secondary treatment device 5, and multiple sets of brushes 23 are fixedly installed at the bottom of the secondary treatment device 5.
