The invention discloses a dust removing method of a surface mine dumping
plough. A mode that a mist-spraying dust removing method is combined with a spraying dust removing method is adopted. Accordingto the mist-spraying dust removing method, a dust removing air-assisted mist-spraying
machine is mounted at the lower part of a discharging arm, and the dust removing air-assisted mist-spraying
machine is mounted at the position, away from a material falling point by the 20-meter horizontal distance, of the lower part of the discharging arm. According to the spraying dust removing method, a
nozzle is mounted at the head part of the discharging arm, and the
nozzle is connected with a dust removing water pipeline. According to the dust removing method of the surface mine dumping
plough, the mode that mist-spraying dust removing is combined with spraying dust removing is adopted and applied to a dust removing
system of the surface mine dumping
plough, spraying dust removing is used for discharging dust removing of the head part, the mist-spraying
machine at the lower part of the discharging arm is mounted at the
fixed position so as to ensure the facts that the mist-spraying distance isfixed relatively and the mist-spraying machine does not need to be moved and arranged frequently due to moving of the discharging arm, the dust removing method can play a better inhibiting effect on secondary flying dust generated after discharging of the dumping plough, and the practical effect is obvious.
