Description

Technical Field

[0001] The utility model relates to the technical field of asphalt spreading, in particular to a spreading frame of an asphalt spreading vehicle. Background Art

[0002] Asphalt distributors can be used to supply asphalt binder to loose soil, build asphalt stabilized soil pavement or pavement base, and spread asphalt when building high-grade highways. In highway maintenance, the vehicle can also be used for asphalt overlay, spraying and other operations. Asphalt distributors include vehicle chassis, asphalt tank, asphalt pumping and spreading system. The asphalt nozzles of the spreading system are distributed on the spreading frame to spread liquid asphalt.

[0003] The uniformity of the asphalt spreading system is an important factor in testing the quality of the construction surface. The uniformity of the asphalt spreading system is achieved through evenly distributed asphalt nozzles. The asphalt nozzles of existing asphalt spreaders are spaced on the spreading frame. The denser the distribution of the asphalt nozzles, the better the uniformity of the spraying. The number of asphalt nozzles distributed on a certain length of the spreading frame is limited, and the large spacing between the two asphalt nozzles will affect the amount of spraying at the junction of the spraying, and the accuracy and uniformity of the emulsified asphalt sprayed on the unit area are difficult to control. At the same time, with the development of science and technology, the designed road surfaces are getting wider and wider. The traditional asphalt spreader is limited by the width of the body, so the spreading range is limited. For this reason, we provide a spreading frame for an asphalt spreader. Utility Model Content
