Problems solved by technology

[0002] At present, the operation control part of the full hydraulic drilling rig for coal mines is mainly composed of standard multi-way valves, various functional valves, valve plates and rubber hoses. The standard multi-way valves are connected with functional valves, valve plates, etc. For a long time, it will cause many problems such as many connecting hoses, confusing connections, and small maintenance space.
[0003] In view of this, the present invention aims to propose an integrated linkage control valve group for a fully hydraulic drilling rig used in coal mines. It is difficult to connect various devices externally, and the structure is simple and compact, and the space occupied is small
