Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression equipment, in particular to a mine spray dust suppression equipment. Background Art

[0002] During the mine production process, a large amount of dust is generated by the crushing of coal and rock. The concentration of coal dust reaches the explosion range. When it encounters a fire source in an aerobic environment, a dust explosion will occur, threatening the lives of underground workers. At the same time, workers inhale a large amount of dust, which seriously endangers their health. Coal miners work in an environment with excessive dust concentration for a long time and are prone to pneumoconiosis. Therefore, it is necessary to use dust reduction work in the production environment of coal mines to ensure the safety of workers' lives.

The supporting cross plate is arranged on the inner side of the mine. The top of the supporting cross plate is fixedly connected to the water tank. One side of the top of the water tank is fixedly connected to the articulated rod. The adjusting rod is driven to rotate along the hinge point of the articulated rod through the extension of the telescopic end of the electric cylinder, so that one end of the adjusting rod is lifted upward, and then the dust reduction atomizing nozzle is driven to adjust the height. The first gear is driven to rotate a certain angle on the rotating shaft through the rotation of the rotating end of the motor. The first gear drives the fixed rod to adjust the dust reduction atomizing nozzle to a certain angle. The angle of the dust reduction atomizing nozzle is adjusted according to the use needs, and the dust reduction atomizing nozzle is supported at the same time.
