Borer rod magazine, for ground boring device, has driven drill string and guide frame, to magazine borer elements in rows, with separation elements arranged between adjacent borer elements

摘要

The magazine (22) has a driven drill string (12), which is collapsed and extended by borer elements (4). The magazine has a guide frame (5), in which borer elements parallel to the drill string are magazined in rows one on top of the other. An output opening outputs the borer elements in a coaxial position, where when one element is output, the other elements are drawn back into the output opening. The magazine is formed as a stacker magazine, in which borer elements are stacked in a non-positive fitting arrangement. At least one separation element (2) is arranged between adjacent borer elements in the stacker magazine, to form the non-positive fitting arrangement on both sides. The separation elements slide in the guide frame, to draw the borer elements into the output opening.
