一种矿山开采钻进装置
By designing a rotating sleeve with an impeller and a pitch-swinging atomizing nozzle, combined with hydraulic system adjustment, efficient dust suppression in mining drilling equipment has been achieved. This solves the problems of limited coverage and dust fallback in traditional dust suppression methods, and improves mixing efficiency and coverage effect.

AI Technical Summary
Traditional dust suppression methods have limited coverage, low mixing efficiency of water mist and dust, and problems with dust settling.
A mining drilling device was designed, which uses a rotating sleeve with an impeller and an atomizing nozzle that can be tilted and oscillated. The rotating sleeve converts the fluid kinetic energy of the water supply system into mechanical energy, causing the atomizing nozzle to rotate and actively mix with the dust. Combined with the hydraulic system to adjust the nozzle angle and control the airflow, a dynamic water curtain and airflow are formed to achieve multi-mode synergistic dust suppression.
It significantly improves the contact efficiency and coverage of water mist and dust, dynamically inhibits dust diffusion, effectively prevents dust from falling back, and improves dust suppression efficiency and coverage.
