Description
technical field [0001] The invention relates to a mining device, in particular to an automatic hydraulic protection device for a coal mining machine. Background technique [0002] The technology of comprehensive mechanized coal mining face continues to develop, and the layout of the working face is gradually developing towards a large mining height. During the inspection and maintenance of the coal machine, personnel enter the side of the coal wall, and their bodies are below the side guard of the bracket and inside the fuselage of the coal machine. There is no side protection facility on the coal wall in this area. Affected by the mining stress, the coal body is prone to fragmentation, causing harm to maintenance personnel. Contents of the invention [0003] The purpose of the present invention is to provide an automatic hydraulic protection device for a coal shearer that is safe to use. [0004] To achieve the above object, the technical solution adopted in the present...
