Description

Technical Field

[0001] The utility model relates to the technical field of pavers, in particular to an asphalt concrete paver. Background Art

[0002] An asphalt concrete paver is a machine used to evenly spread asphalt mixture on the road base and to perform preliminary vibration and leveling. Asphalt paver can accurately ensure the thickness, width, road camber, flatness and density of the paving layer, it is widely used in asphalt mixture paving operations in projects such as highways, urban roads, parking lots and airports. It can also be used for paving operations of stabilized materials and dry hard cement mixtures.

[0003] Patent No. CN218147638U discloses an asphalt concrete paver, including a main body, wheels are installed on both sides of the main body, a control panel is fixedly installed on the side of the main body, handles are fixedly connected to the two sides of the control panel, a connecting bracket is fixedly connected to the side of the main body, a support plate is fixedly installed on the lower end of the connecting bracket, a scraper is fixedly installed on the side of the support plate, a rectangular block is fixedly installed on the side of the support plate, and a guide rod is fixedly connected to the side of the rectangular block. At this time, the guide rod is used to move the movable brush plate on the surface of the scraper. The use of the movable brush plate can facilitate people to quickly clean the unsolidified asphalt and concrete on the scraper surface. When the movable brush plate moves, the oblique knife moves with the movable brush plate. The oblique knife can remove the semi-solidified asphalt and concrete on the scraper, so that people can quickly clean the asphalt and concrete on the scraper without affecting the subsequent use of the paver.

[0004] The existing asphalt concrete paver has the disadvantages that: there is no material storage structure on the main body, and the asphalt concrete cannot be stored, and the asphalt concrete needs to be poured on the ground before paving. For this reason, we propose an asphalt concrete paver. Utility Model Content
