Drilling machine capable of automatically ascending and descending drill rod

A drilling machine capable of automatically ascending and descending a drill rod comprises a chassis walking unit, a supporting device, a drill rod feeding device and an automatic drill rod box device, the supporting device is installed on the chassis walking unit, the drill rod feeding device is installed on the supporting device, and the automatic drill rod box device is installed on the drill rod feeding device. The drilling machine capable of automatically ascending and descending the drill rod has the positive effects that the width of the vehicle body is not increased while a stable supporting effect is achieved, and the movement of the drilling machine is not influenced, so that the drilling machine can normally advance in a roadway. On the premise that the capacity of the drill rods in the automatic drill rod box device meets the requirement, the structure is simpler, the action is reliable, the moving space needed in the drill rod moving process is greatly reduced, the number of the drill rods is eff
