The lubricating valve block group is provided with two groups, one of which is set to control the left lubricating oil cylinder of the left rocker arm of the shearer and the lubrication of the left bracket. Valve block group, the other group is set to control the right rocker arm oil cylinder and the right bracket lubrication of the coal mining machine right lubricating valve block group.

The technical problem to be solved by the utility model can also be further realized through the following technical solutions. There are 4 quick-plug connection joints on the left lubricating valve block group, and 2 of them are respectively connected to the coal mining through the mining hydraulic rubber hose. The front end of the piston rod of the left rocker cylinder of the coal mining machine and the lubricating grease injection port at the tail of the left rocker cylinder of the coal mining machine are connected. The injection ports are connected.

The technical problem to be solved by the utility model can also be further realized through the following technical solutions. There are 4 quick-plug connection joints on the right lubricating valve block group, and 2 of them are respectively connected to the coal mining through the mining hydraulic rubber hose. The front end of the piston rod of the right rocker cylinder of the coal mining machine and the lubricating grease injection port at the tail of the right rocker cylinder of the coal mining machine are connected. The injection ports are connected.

The technical problem to be solved by the utility model can also be further realized through the following technical solutions, the lubricating valve block body is provided with a connecting counterbore fixedly connected with the coal mining machine body through a hexagon socket head screw.

Compared with the prior art, the utility model utilizes the oil cup installed on the lubricating grease inlet connected with the off-board lubricating pump, and the quick-plug connection joint installed on the lubricating grease outlet, which makes the pipeline connection very convenient It is fast and can ensure centralized lubrication, which solves the time-consuming and labor-intensive problem of manual grease injection for coal shearers, and achieves the goals of good lubrication, reduced friction, reduced power consumption and extended equipment service life.
