Description

Dust fall device for open pit coal mine field Technical Field The utility model relates to the technical field of dust fall of coal mine sites, in particular to a dust fall device of an open pit coal mine site. Background Coal mines are areas where human beings mine coal resources in coal-rich mining areas, when the distance between a coal bed and the ground surface is very short, the coal is generally excavated by directly stripping off the earth surface soil layer, which is an open pit coal mine, and dust fall measures of the open pit coal mine are very important, mainly to reduce the harm of coal dust to the environment and human bodies. The utility model provides a dust settling device (the authorized bulletin number of which is CN 209457969U) for a coal mine field, which can realize the fixation of a spray head after the adjustment of the height and the deflection angle by manually adjusting a fixing pin and a rotating pin, and the dust settling device has the functions of adjusting the height and the deflection angle of spraying, but is inconvenient to realize the adjustment of reciprocating lifting and deflection of the spray head in the process of spraying water and settling dust on the coal mine field by the actual dust settling device, so that the coverage range of spraying water and settling dust is limited, and the working efficiency of the dust settling device is reduced. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a dust settling device for an open pit coal mine field, which is used for solving the problems.
