External atomizing nozzle of fully-mechanized road header

The utility model relates to a coal mine atomization device, in particular to an external atomizing nozzle of a fully-mechanized road header, and solves the problems of difficulty in effectively treating coal dust and high probability of blocking water outlet holes caused by an irrational structure of the conventional external atomizing nozzle. The external atomizing nozzle of the fully-mechanized road header comprises a nozzle body which is arranged on the fully-mechanized road header, wherein a plurality of water outlet holes are uniformly distributed in the front end face of the nozzle body; and the rear end face of the nozzle body is provided with a quick coupling which has a diameter of 13 mm and is communicated with the water outlet holes. The external atomizing nozzle has the advantages of rational and reliable structural design, capabilities of solving the problem of difficulty in treating the coal dust on the conventional working face, greatly improving the working environment of the working face and
