Description

Technical Field

[0001] The utility model relates to the technical field related to pavers, in particular to an asphalt paver for municipal engineering. Background Art

[0002] An asphalt paver is a machine that spreads asphalt mixture evenly on the road base and performs preliminary vibration and leveling. During the paving process, the asphalt paver first stores the material in the paver's storage area, then uses a screw or conveyor belt to spread the asphalt material on the ground, and then uses a spreading plate to level it.

[0003] During the process of leveling the asphalt on the paving plate, asphalt will stick to the bottom surface. If it is not cleaned in time, the long-term accumulation of asphalt will affect the leveling effect of the paving plate. However, since the bottom surface of the paving plate is facing downward and the distance between it and the ground is limited, it is inconvenient to clean. Utility Model Content
