Abstract
A device for earth or rock drilling has a mast, a drill drive with a shaft for rotatably driving a drill rod, a drill drive carriage, on which the drill drive is arranged, movably supported along the mast, and an oscillation generating drive disposed behind the drill drive in a drilling direction connected to the drill rod for transmitting an oscillation. A rear connecting end of the shaft or the drill rod projects rearwards from the drill drive. A rotary coupling with a first coupling piece is provided on the connecting end in an axially fixed and torque-proof manner, and a second coupling piece is axially fixed and rotatable relative to the first coupling piece. The oscillation drive has a clamping means for releasably clamping the second coupling piece, such that in the clamped state an axially fixed connection is formed between the oscillation drive and the second coupling piece.
