The invention relates to the field of tunnel construction, in particular to a tunnel impact milling excavator. The excavator comprises an excavator body, an excavating arm mechanism, a turnover device, an impact milling and excavating device and an excavator bucket arranged at the tail end of the excavating arm mechanism. The turnover device comprises a turnover seat arranged on the excavator main body, a rotating shaft which is rotationally arranged on the turnover seat and is connected with the digging arm mechanism, and a rotary driving device which is arranged on the turnover seat and is in driving connection with the rotating shaft; the impact milling and digging device comprises an impact milling and digging mechanism, a telescopic rotating arm of which the two ends are rotationally connected with the impact milling and digging mechanism and the digging arm mechanism respectively, a rotating power device a which is arranged at one end of the telescopic rotating arm and is in transmission connection with the digging arm mechanism, and a rotating power device b which is arranged at the other end of the telescopic rotating arm and is in transmission connection with the impact milling and digging mechanism; and an oil cylinder for adjusting the length is arranged in the telescopic rotating arm. Rock can be drilled firstly, then impacted and fractured, and finally shoveled out through the excavator bucket.
本发明涉及隧道施工领域，具体为隧道冲击铣挖机。其包括挖掘机主体、挖臂机构、翻转装置、冲击铣挖装置以及设置在挖臂机构末端的挖斗；翻转装置包括设置在挖掘机主体上的翻转座、转动设置在翻转座上且与挖臂机构连接的转轴，以及设置在翻转座上并与转轴驱动连接的旋转驱动装置；冲击铣挖装置包括冲击铣挖机构、两端分别与冲击铣挖机构和挖臂机构转动连接的伸缩旋转臂、设置在伸缩旋转臂一端并与挖臂机构传动连接的旋转动力装置a，以及设置在伸缩旋转臂另一端并与冲击铣挖机构传动连接的旋转动力装置b，伸缩旋转臂内置调节长度的油缸。本发明能对岩石先钻孔，后冲击破裂，最终通过挖斗铲出。
