Abstract (en)
[origin: EP2050923A1] The device (1) has a rotary transmission with a rotary head attached at an impact head (3). The rotary head is connected with a retaining element (14) designed as a drill head (15) for a drill pipe (16). The rotary head is provided with a continuous axial drill hole in which a fixing bar (24) is inserted. The fixing bar has an end region held in the impact head in a torque proof manner. Another end region is connected with a drill sample sheath (19) by connection elements. The drill sample sheath is inserted in the drill pipe, and a drill sample core is accommodated in the sample sheath. An independent claim is also included for a method for executing a drilling process with a drilling device.
