なければならない。Therefore, in order to reduce such energy loss, a top hammer type drilling machine such as a down-the-hole drill having a striking mechanism near a drill bit is used. In recent years, for the reasons of energy saving, improvement of efficiency, suppression of noise due to exhaust noise, etc., most of the tail hammer type punching machines have adopted the hydraulic hammering method. Adoption of a striking method is under consideration. If a hydraulic hammering method is adopted for the top hammer type punching machine, the striking force, the number of hits, and the efficiency can be dramatically improved. For that purpose, it is necessary to provide a hydraulic circuit and a pressure fluid circuit for discharging powder in the drill rod, and to add this drill rod according to the length of the drilling hole. It must be stored so that oil leakage and dust adhesion do not occur, and the drill rod can be easily attached and detached.
