  • Publication number: 20260049460
    Abstract: A material-receiving device for a suction excavator has an articulated tube support and a suction tube. A first, proximal end of the articulated tube support is attachable to the suction excavator by a rotationally movable fastening mount. At a second distal end, the articulated tube support comprises a suction connecting piece connected to the suction tube. The articulated tube support comprises n?3 links, between each of which a hinge joint with an associated drive is formed. All the hinge joints have the same degree of freedom, so that the links are pivotable in a common plane. A rotary joint is located between the last, distal hinge joint, on which the suction connecting piece is located, and the first hinge joint. The rotary joint has a different degree of freedom than the hinge joints, so that the link disposed subsequently to the rotary joint can be moved out of the plane.
