In the embodiment of the present invention, the air pipe 61 and the water pipe 62 are provided with electromagnetic valves.

Through adopting above-mentioned technical scheme, all be provided with the solenoid valve on trachea and the water pipe and conveniently control trachea and water pipe, and then can realize that aerial fog shower nozzle jet-propelled mode that forms the water smoke alone, spray water alone and spray water simultaneously.

In conclusion, the mining drilling machine provided by the invention has the functions of automatically replacing the rod, cooling and reducing dust, and is more convenient to adjust the position of the drilling machine and higher in adaptability.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
