Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of maintenance construction equipment, in particular to a highway roadbed and pavement maintenance construction equipment. Background Art
[0002] Due to the high speed and heavy traffic on highways, potholes often appear on the surface of highway roadbeds. To prevent these potholes from affecting driving safety, construction workers are often required to fill the potholes with asphalt raw materials and then use leveling tools to maintain them.
[0003] Most of the existing highway roadbed and pavement maintenance construction equipment has a relatively simple structure. Since asphalt has a certain viscosity, some asphalt raw materials will stick to the screed after use. If it is not cleaned in time, it will cause the raw materials to clump, which will be inconvenient for construction workers to clean it and will affect the next use. Utility Model Content
[0004] The technical problem to be solved by the utility model is that when the filled road surface is leveled, asphalt will be adhered to the equipment and is not easy to be removed.

[0006] As an improvement, the leveling structure includes a slide groove 1 with an arc-shaped cross-section on both side walls of the fixed groove, a slider 1 with a circular cross-section is slidably connected inside the slide groove 1, and the two left-right symmetrical sliders are rotatably connected to the leveling wheel. A plurality of leveling structures are arranged in an array along the edge of the fixed groove, and the leveling structure is used to level the filled road surface.
[0007] As an improvement, the auxiliary buffer structure includes a slide groove 2 with a trapezoidal cross-section located on both side walls of the fixed groove, and a slider 2 with a trapezoidal cross-section is slidably connected inside the slide groove 2. A plurality of groups of slide grooves 2 and sliders 2 are arranged in an array along the edge of the fixed groove, and the left-right symmetrical sliders 2 are fixedly connected to the support plate.
[0008] As an improvement, the buffer structure includes a second telescopic rod located in the middle of the upper side of the support plate and connected to the fixed groove. A plurality of groups of buffer springs are arranged in an array along the edge between the support plate and the fixed groove. The buffer structure is used to level the structure for buffering.
[0009] As an improvement, the anti-sticking structure includes a fixing strip located on one side of the leveling wheel, and a scraper with an arc-shaped cross-section is connected to the end of the fixing strip. The anti-sticking structure is used to remove asphalt on the leveling wheel.
