The screw transporter has a transport channel (15) movable sideways towards the motor tool and containing a rotatably arranged screw (20). It has a feed-in end with a forwardly facing aperture (23) at the level of the travel track (3), and a feed-out end with an aperture (24) above the travel track. - A processing unit at the transporter feed end has a first shaft blade (25) on one side of the feed-in aperture for levelling of the part of the ditch (4) connecting to its edge. Another shaft blade on the other side of the feed-in aperture scrapes a part of the travel track near the ditch. A third shaft blade (27), which downwardly limits the feed-in aperture, levels in the ditch bank (2). The three shaft blades connect the material loosened by the working into the transport channel feed-in aperture. |
