description | The utility model discloses efficient coal field fire extinguishing drilling equipment which comprises an air drill body and an L-shaped fixing plate, the L-shaped fixing plate is fixedly arranged at the top of the air drill body, a mounting plate is movably arranged on one side of the L-shaped fixing plate, and a drill cylinder is rotationally arranged at the top of the mounting plate through a bearing. And one end of the drilling cylinder extends to the bottom of the mounting plate. According to the efficient coal field fire extinguishing drilling equipment, the nitrogen making machine is arranged at the top of the air drill body, and the nitrogen making machine is connected with the drill barrel through the air pump, so that a traditional drill barrel matched with external air can be replaced by nitrogen in the nitrogen making machine, and air is replaced by nitrogen inert gas; the problems that a fire source is generated by drilling friction of drilling equipment and a fire source in a combustion-supporti |
