Description

Technical Field

[0001] The utility model relates to the technical field of asphalt paving, in particular to asphalt paving equipment. Background Art

[0002] Asphalt can be mainly divided into coal tar asphalt, petroleum asphalt and natural asphalt. Asphalt paving is often used for paving roads such as highways, roads, sidewalks and parking lots. It is usually a thick, viscous black liquid made from different levels of petroleum residue or tar through a series of processing and treatment. The road surface paved with asphalt has the advantages of high temperature stability, low temperature crack resistance and water stability. It can fill cracks and potholes on various road surfaces, and can also make the road smoother, more durable, non-slip and water-resistant, etc., improving the safety of drivers and pedestrians. There are many kinds of asphalt paving equipment currently available on the market, but there are still some disadvantages;

[0003] For example, in actual use, general asphalt paving equipment pours asphalt into a raw material barrel for flowing out and paving. However, the asphalt is prone to precipitation and solidification inside the raw material barrel, which may cause blockage when the asphalt is discharged. At the same time, the raw material barrel generally only has a small discharge port, which may cause uneven asphalt discharge and uneven paving. In addition, if the asphalt is not compacted after being paved, there will be gaps between the asphalt pavings, which may cause instability in the road paving. Therefore, we propose an asphalt paving equipment to solve the above problems. Utility Model Content
