发明名称 DEVICE FOR CONVEYING AWAY DRILLINGS
摘要 <p>The invention relates to an apparatus for removing drill cuttings loosened by a drilling tool (113) during the operation of producing a drill hole (101, 102) for laying a pipeline, having at least one pump (12) for pumping out drilling fluid mixed with the drill cuttings, and having at least one receiving body (11) with at least one receiving chamber (17), which is connected to a drill-cuttings region (117) behind the drilling tool (113) via openings (14). It is therefore an object of the invention to create an apparatus for removing drill cuttings which makes it possible for the drill cuttings to be transported away reliably using a pressure-delivery method. The solution of the invention provides, on the receiving body (11), a receiving element (13), which is intended for receiving the drill cuttings mechanically and on which are arranged at least some of the openings (14) via which the drill cuttings pass into the receiving chamber (17).</p>
