[0002] Coal mining machine is one of the important equipment to realize the mechanization and modernization of coal mine production. Mechanized coal mining can reduce physical labor, improve safety, and achieve the goals of high output, high efficiency and low consumption. Coal mining machine is divided into four types: sawing, planing, drilling and milling. Coal mining machine is a large and complex system integrating mechanical, electrical and hydraulic. With the development of coal industry, coal mining machine has more and more functions, and its own structure and composition are more and more complex, so the reasons for failure are also complicated.

[0003] Due to the harsh working environment of the coal mining machine and the large dust pollution, the gear meshing part of the coal mining machine will be polluted and the meshing wear of the gear will be increased. Therefore, it is necessary to lubricate the rocker arm gear set of the coal mining machine regularly. Among them, the utility model patent with announcement number CN213207230U discloses a forced lubrication device for coal mining machine. However, the above patent still has certain shortcomings when used. The lubricating oil tank and the oil pipe are mostly exposed in place. In complex coal mining sites, it is easy to cause damage to the lubricating oil tank and the oil pipe, which is not convenient for the safe lubrication operation of the coal mining machine gear assembly. For this reason, we propose a coal mining machine lubrication device to solve the above problems. Utility Model Content
