Description

Technical Field

[0001] The utility model relates to the technical field of asphalt mixture paving machines, in particular to an asphalt mixture paving machine for coal mines. Background Art

[0002] Humans mine coal resources in coal-rich mining areas, which are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal, which is an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine coal, which is an open-pit coal mine. The coal mined in the coal mine needs to be transported out, in addition to being transported by rail, it can also be transported by car, so roads need to be built in the coal mine for the transportation of coal.

[0003] As disclosed in the authorization announcement number CN204676398U, an asphalt mixture paver is disclosed, including a frame, a hopper, a screw feeder, a scraper conveyor, a screed, a cab, a left crawler arranged on the left side of the frame, a right crawler arranged on the right side of the frame, and a travel control system. The cab is provided with a control panel, a rotating seat, and a control panel rotating mechanism for driving the control panel to rotate synchronously with the rotating seat. The cab is provided with a seat rotating shaft, a seat bracket is hinged on the seat rotating shaft, and the rotating seat is installed on the seat bracket. The frame is provided with a hydraulic lifting mechanism for driving the screw feeder to rise and fall. The asphalt mixture paver can realize the synchronous rotation of the control panel with the rotating seat by setting the control panel rotating mechanism, and can quickly and effectively realize the lifting and lowering of the screw feeder by setting the hydraulic lifting mechanism, which is more convenient to use and more user-friendly in design. However, it is not convenient to use in places with poor site conditions and is not convenient for leveling asphalt mixture during use. For this reason, we propose an asphalt mixture paver for coal mines. Utility Model Content
