[0002] During the coal mining process, due to the small particle size and light weight of dry coal powder, it is easily affected by external factors and floats in the air, which in turn has a negative impact on the health of coal mine workers. Therefore, spray dust suppression equipment is widely installed in many places in coal mines to settle the coal powder suspended in the air. Among them, the most commonly used is the spray nozzle, which can disperse water into droplets and spray them to the dust source to suppress and capture the dust.

[0003] At present, most coal mines are equipped with spray nozzles for spray dust reduction. Since some coal mines have large spaces, the range of dust reduction required is also large. At this time, more spray nozzles need to be installed in the space for dust reduction. Therefore, there is a need for a dust spray dust reduction equipment for coal mines. The range of dust reduction of the spray nozzles can be expanded through a swinging structure, so as to avoid the need to install more spray nozzles in the larger space of the coal mine, thereby reducing cost consumption.
