Description

[0002] Mining industry is an important industrial department, it involves the excavation of natural mineral, these minerals can be solid (such as coal and mineral), liquid (such as crude oil) or gas (such as natural gas), when solid mineral such as coal mine is mined, it needs to use the heading equipment to carry out the heading of roadway or mining face, in the heading process, a large amount of dust will be produced, although the spraying equipment is generally installed around the heading head of heading equipment, but only can play the role of reducing part of dust, therefore, in some working scenes, the fog gun machine and other equipment are used to aim at the heading position to further reduce dust.

[0003] The fog gun machine is based on the wind sending principle and high pressure atomization technology. It first uses a high pressure pump and a fine atomization nozzle to atomize water to form fine water mist particles. Then, the wind volume and wind pressure generated by the fan are used to transport the atomized water mist particles to the area where dust reduction is needed. After the water mist particles combine with the dust particles in the air, the dust particles will settle to the ground due to gravity, thereby achieving the purpose of dust reduction. However, in actual operation, it is difficult to achieve 100% adsorption of the dust in the spraying area, and some dust particles will still float away. Moreover, since the spraying distance of the fog gun machine is generally far, the water mist will not fall until it is far away from the fog gun machine. Therefore, some dust particles will float towards the direction of the fog gun machine through the low area where there is no water mist, and this part of dust particles is difficult to collect. In order to further improve the dust reduction effect, we propose a mining construction dust falling equipment. SUMMARY
