Atomizing nozzle for coal mine cutting equipment

The invention discloses an atomizing nozzle for coal mine cutting equipment. The atomizing nozzle for the coal mine cutting equipment comprises a nozzle seat and a nozzle body arranged in the nozzle seat, a nozzle core is arranged in the nozzle body, the nozzle core and the inner wall of the nozzle body form a vortex chamber, a spiral groove extending along the length direction of the nozzle core is formed in the outer wall of the nozzle core, a spiral water passage used for conveying water entered from a water inlet of the nozzle seat to the vortex chamber is formed between the spiral groove and the inner wall of the nozzle body, and an atomizing spray hole passage for spraying the water in the vortex chamber in an atomizing mode is opened in the end of the nozzle body far away from the nozzle core. The atomizing nozzle uses the rotation and centrifugation combined jet flow principle, air is sucked to atomize the water by means of the high-speed jet flow of liquid and negative pressure, the finally sprayed conical solid fog curtain is large in taper angle, and moreover, the spray flow speed is large, the effective spray range is far, the fog density is large, coal dust is difficult to pass through the fog curtain under normal circumstances, the dust prevention effect and cooling effect are ideal, the blockage is rarely generated, and the service life is long.
