Description

Technical Field

[0001] The present invention relates to the technical field of highway construction, in particular to an adjusting device for an asphalt paver used in highway construction. Background Art

[0002] At present, asphalt paver is a kind of engineering machinery used for paving asphalt concrete pavement. It is mainly used to evenly spread the mixed asphalt mixture on the prepared roadbed and base layer, and perform preliminary compaction to create good conditions for subsequent rolling work to form a flat and solid asphalt pavement.

[0003] When laying asphalt, existing asphalt pavers install a mechanical sweeping brush at the front end of the paver. The brush is similar to a large rotating broom and can sweep dust, leaves, pebbles and loose debris on the road surface to the roadside when it rotates at high speed. However, the high-speed rotating sweeping brush frequently contacts the road surface, and the bristles are subjected to greater friction, resulting in faster wear. This not only increases the maintenance cost of the equipment, but also requires frequent shutdowns to replace the bristles, affecting the construction progress.

[0004] However, the existing technology is to install a replaceable bristle protective cover on the cleaning brush. The protective cover is made of wear-resistant and impact-resistant materials, such as high-strength rubber and polyurethane. When the cleaning brush encounters sharp debris, the protective cover first contacts the debris, plays a buffering and protective role, and reduces damage to the bristles. However, during long-term use, the rubber will age due to the influence of sunlight, oxygen, temperature, humidity and environmental factors. The aged rubber will become hard and brittle, lose its original elasticity and flexibility, and its impact resistance and buffering effect will be greatly reduced, thereby reducing the protective effect on the bristles, resulting in reduced construction efficiency and increased construction costs.
