However, due to the large amount of dust generated at the transfer point during the belt transportation process, the coal dust will be secondary-flying, which will not only cause physical damage to the operators, but also pose a risk of coal dust explosion. Therefore, it is necessary to use corresponding automatic spray devices to reduce dust.

[0003] The automatic spray device for underground coal mines disclosed in announcement number "CN202417568U" includes a main body, a water inlet device, a thrust device, a power transmission rod and a spray head. One end of the main body is connected to the water inlet device, and the other end is connected to the thrust device. It has a novel structure, simple operation and is practical.
