[0002] The coal mining machine is a large and complex system integrating mechanical, electrical and hydraulic functions, in which the coal mining machine travel box is the power output actuator of the coal mining machine traction system. Because the internal gear transmission system is an open transmission, and the travel wheel and the pin row of the scraper conveyor are non-conjugately meshed, under the harsh working conditions of coal slag pollution and vibration, the friction resistance between the travel wheel and the pin row is large during the travel process, and the noise generated is also very loud. The traction motor often runs in overload, causing serious wear on various components. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the utility model provides an oil dripping hole and an adjusting rod, and controls the gap between the adjusting rod and the oil dripping hole, so that the lubricating oil flows out of the oil dripping hole and falls into the meshing place of the traveling wheel and the pin row below, thereby reducing the friction force and the noise generated by the friction, thereby achieving the effect of reducing the wear of the traveling wheel and the pin row and extending the service life.

[0004] The technical solution adopted by the utility model is a lubrication device for a coal mining machine traveling box, comprising a lubrication box, a box cover, and an adjusting rod, wherein a refueling hole is provided at the top of the lubrication box, an oil dripping hole and a drill hole are provided at the bottom of the lubrication box, the box cover is used to seal the refueling hole, one end of the drill hole extends to the outer wall of the lubrication box, the other end of the drill hole is connected to the oil dripping hole, the A end of the adjusting rod is inserted into the drill hole, the adjusting rod can be telescopically moved in the oil dripping hole, and the opening and closing degree of the oil dripping hole is controlled by the adjusting rod.

[0005] Furthermore, the B end of the adjusting rod has an external thread, and the B end of the adjusting rod is threadedly connected to the lubrication box, and the adjusting rod is telescopically moved along the drilled hole by rotating the adjusting rod.

[0006] Furthermore, the oil drip hole is located directly above the meshing position of the traveling wheel and the pin row.

[0007] Furthermore, a sealing ring is sleeved on the middle part of the adjusting rod.

[0008] The utility model discloses a lubricating device for a traveling box of a coal mining machine, which has the beneficial effect of arranging an oil dripping hole and an adjusting rod, and controlling the size and dripping speed of the lubricating oil by controlling the gap between the adjusting rod and the oil dripping hole, thereby achieving lubrication of the meshing portion between the traveling wheel and the pin row, reducing friction and extending the service life.

[0013] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0014] In order to further understand the content of the utility model, this technical solution is further explained below in conjunction with specific implementation methods.

[0015] Example 1: Figures 1-2As shown, the present embodiment provides a lubrication device for a traveling box of a coal mining machine, comprising a lubrication box 1, a box cover 2, and an adjusting rod 3. The lubrication box 1 is embedded in the traveling box of the coal mining machine, and the top of the lubrication box 1 is fitted with the top of the traveling box of the coal mining machine, wherein a refueling hole 4 is provided at the top of the lubrication box 1, and an oil dripping hole 5 and a drill hole are provided at the bottom of the lubrication box 1. The box cover 2 is used to seal the refueling hole 4, one end of the drill hole extends to the outer wall of the lubrication box 1, and the other end of the drill hole is connected with the oil dripping hole 5. The A end of the adjusting rod 3 is inserted into the drill hole, and a sealing ring 6 is sleeved in the middle of the adjusting rod 3. The sealing ring 6 is used to seal the gap between the adjusting rod 3 and the drill hole to ensure that the lubricating oil does not flow out. The B end of the adjusting rod 3 has an external thread, and the B end of the adjusting rod 3 is threadedly connected to the lubrication box 1. The A end of the adjusting rod 3 penetrates into the oil dripping hole 5 after passing through the drill hole. The adjusting rod 3 is rotated to make the adjusting rod 3 telescopically move along the drill hole, thereby adjusting the gap between the A end of the adjusting rod 3 and the oil dripping hole 5, so as to control the opening and closing size of the oil dripping hole 5.

[0016] The oil dripping hole 5 is located just above the meshing of the running wheel 7 and the pin row 8 of the scraper conveyor to achieve the best lubrication effect. Specifically, in the actual application process, the lubricating oil is injected from the filling hole 4, the lubricating oil is carried in the lubrication box 1, and the adjusting rod 3 is rotated so that there is a gap between the end of the adjusting rod 3A and the oil dripping hole 5, and then the lubricating oil flows out of the oil dripping hole 5 and falls into the meshing of the running wheel 7 and the pin row 8 below, reducing the friction force and the noise generated by the friction, thereby reducing the wear of the running wheel 7 and the pin row 8 and extending the service life.
