Description

Technical Field

[0001] The utility model relates to the technical field of coal mine mining and transportation, in particular to a tunneling coal conveying device for coal mine mining. Background Technique

[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas. Generally, it is divided into underground coal mines and surface coal mines. When the coal seam is far from the surface, generally, underground roadways are dug to mine coal, which is an underground coal mine. When the distance between the coal seam and the surface is very close, generally, the surface soil layer is directly stripped to mine coal, which is a surface coal mine. During the coal mine mining process, a roadheader is used. Among them, a roadheader is a machine used to dig straight underground roadways. The roadheader mines the ore to the scraper through the cutting part, and conveys the cut ore to the conveyor through the scraper. Finally, the coal is conveyed out from the conveyor.

[0003] There are still some deficiencies in the existing conveying and coal transporting devices during use. When the coal is conveyed, it often bumps on the conveyor belt. The traditional conveyor belt can only play the role of conveying ore, and cannot reduce the impact force generated by the bumps of the coal on the conveyor belt. Moreover, it does not have the function of conveyor belt deviation correction, which is not convenient for the safe and stable transportation of coal blocks. For this reason, we propose a tunneling coal conveying device for coal mine mining to solve the above problems. Content of the Utility Model

The bottom end of each support rod penetrates through the sliding hole and extends below the installation bracket. Two U-shaped spring pieces are fixedly connected to the upper surface of each installation bracket. The upper surface of each U-shaped spring piece is fixedly connected to the bottom surface of the guide wheel bracket. A second shock-absorbing spring is fixedly connected to the inner wall of each U-shaped spring piece.
