摘要

(57) Abstract As for this invention it regards the soundproof casing in the rotary rock drilling rig. The rotary rock drilling rig, has portable possible boom (3) to various directions, the portable possible carrier (2) is possessed. Boom (3) is needed the excavation tool which (4) having for the free edge, excavation tool (4) is surrounded in the casing (5) at the time of conceiving in this inventing, as for that casing, prevents the fact that the noise in the time of excavation spreads around. At the time of conceiving in this inventing, as for the casing (5) the feed beam (11) and also, the cradle where boom in order that it moves (3) is installed in the destal (12) vis-a-vis it is laid out. The casing (5) has surrounded the feed beam (11). As for this invention, being something regarding the device which is used in addition pertaining to the rotary rock drilling rig, as for that device, excavation tool (4) and the feed beam (11) you have almost surrounded completely in regard to the casing (5).
