Description

Technical Field

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

[0002] When constructing a road surface, a compactor is needed to compact the soil to ensure the flatness of the road surface. During use, existing road construction compactors use a moving wheel to drive a compacting roller to move back and forth to compact the soil. However, during the compaction process, the soil is laid on the road surface, and the soil is unevenly distributed, which easily causes raised areas on the road surface, making it difficult to level the soil on the road surface, and the road surface compaction effect is not ideal. A Chinese utility model patent with publication number CN221345197U discloses a road construction compactor that uses a flattening tooth plate to level the soil, making the soil relatively flat. However, the following problems still exist: even on a seemingly flat ground, there may be some slight unevenness. The flattening tooth plate angle is not adjustable and cannot compensate for the unevenness well. The flattening tooth plate length cannot be adjusted at will, and only a single-sized compacting roller can be used, which has a narrow range of application. Summary of the Invention
