The dredger has an outrigger with lifting mechanism for the shovel, and a guide rod, both hinged to the dredger frame. The end of the guide rod away from the frame is connected via a common joint to the front end of an advance rod, and the rear end of a shovel arm, the front end of which is fastened rigidly to the shovel. A continuous conveyor (50) is hinged directly to the shovel (S). The end of the shovel arm (H) away from the shovel carries units for the articulated connection between shovel arm and guide rod (L), and advance rod (C). The units are positioned on an imaginary arc abut the pivot shaft (25), and consist of apertures (26) with hinge pins (20). |
