Coal mine ground movable type automatic grouting fire preventing and extinguishing equipment

The invention discloses coal mine ground movable type automatic grouting fire preventing and extinguishing equipment. The grouting equipment comprises a material supply system, a water supply system, a pulping system, a pumping system, a control system and a movable assembly. Firstly, the material supply system and the water supply system convey loess and clear water respectively, and the vibration feeding function is set, so that loess conveying is accelerated; secondly, the control system monitors and controls the material transportation volume of each system in real time, and adjusts the water-soil ratio of slurry; thirdly, the pulping system continuously stirs, mixes and filters the slurry; then, the pumping system utilizes a plunger pump to pressurize and pump the slurry to a grouting point, a reducing flange is arranged to change the pipe diameter of a slurry conveying pipeline, pipeline abrasion is reduced, and the grouting pressure is increased; and finally, the system is integrated in a skid-mounted
