Description

Technical Field

[0001] The utility model relates to the technical field of asphalt paving, in particular to an asphalt paver with adjustable material dropping width. Background Art

[0002] Asphalt is a viscous, black, and highly viscous liquid or semi-solid petroleum with a black surface and is soluble in carbon disulfide and carbon tetrachloride. Asphalt can be mainly divided into three types: coal tar asphalt, petroleum asphalt, and natural asphalt. Among them, coal tar asphalt is a by-product of coking. Petroleum asphalt is the residue after crude oil distillation. Natural asphalt is stored underground, some of which forms mineral layers or accumulates on the surface of the earth's crust, so asphalt needs an asphalt paver with adjustable drop width to spread it.

[0003] For example, an asphalt paver with the authorization announcement number "CN220284539U" sets a heating rod in the heating chamber of the hopper body. Under the power supply of the power box, the hopper body reaches a certain temperature, which can reduce the adhesion of the asphalt mixture poured into the interior of the hopper body in cold conditions, making it easier for construction workers to clean the hopper. However, the asphalt paver heats the asphalt by increasing the temperature of the hopper through the heating rod. Only the surface of the asphalt in contact with the hopper is heated, and other parts of the asphalt cannot be heated. The heating of the asphalt is not sufficient, causing the asphalt to solidify. The solidified asphalt cannot continue to be paved. At the same time, when the material is dropped, the width of the dropped material cannot be controlled. The thickness of the dropped asphalt is the same, and different sections of the road require different thicknesses of dropped material, resulting in a decrease in the working quality of this asphalt paver.
