Abstract
A device for excavating and transporting material, especially earth, the device comprising an excavation appliance that can be rotated about a rotational axis (y) in a rotational direction (u), and a longitudinal conveyor for transporting the excavated material. The excavation appliance comprises an impeller having a conically extending guide surface arranged around the rotational axis (y) in a rotationally symmetrical manner, and guide vanes which radially protrude from the conical guide surface and form an acute angle in relation to the rotational axis (y).
Claims8
An apparatus for excavating and transporting away soil material, comprising:
- two impeller wheels (12, 14) which can be rotated about an axis of rotation (y) in a direction of rotation (u), with a conically extending guide surface (20) arranged about the axis of rotation (y) in a rotationally symmetrical manner and with guide vanes (22) which project radially from the conically extended guide surface (20) and which form an acute angle with respect to the axis of rotation (y), and
- a conveyor belt (18) for transporting away excavated material (41), said conveyor belt being arranged between the impeller wheels (12, 14), said conveyor belt (18) having a conveying direction (x) which is at a right angle with respect to the axis of rotation (y),
- wherein, the conically extending guide surface (20) of the impeller wheels (12, 14) having a narrowed end adjoining the conveyor belt (18) and forming a run-off surface for the excavated material (41),
- wherein, the guide vanes (22) are bounded by two lateral edges (24, 26) which are parallel to one another, and the width of the guide vanes (22) corresponds substantially to the width of the conically extending guide surface (20), and
- wherein an inner lateral edge (24) of the guide vanes (22) adjoins a fixed guide plate (30) at least in a region below the conveyor belt (18).
