Description

technical field [0001] The invention relates to a coal mine underground equipment, in particular to an underground coal mine slotting machine. Background technique [0002] In coal mine underground roadway construction operations, after the overall construction work is completed, individual roadways still need to be repaired or slotted partially, such as the installation of air doors and the sealing of the roadway. Grooving operation is carried out with the top plate, and secondary construction is carried out. Originally, this kind of operation was completely dependent on manual work, and many people used simple crushing tools, which resulted in low construction efficiency and great potential safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a coal mine underground slotting machine with compact structure, flexible joints, large swing range, high reliability and convenient installation and disassemb...
