CA 2666151

The invention relates to a device for excavating and transporting material, especially earth, said device comprising an excavation appliance that can be rotated about a rotational axis (y) in a rotational direction (u), and a longitudinal conveyor (18) for transporting the excavated material (41). The excavation appliance comprises an impeller (12, 14) having a conically extending guide surface (20) arranged around the rotational axis (y) in a rotationally symmetrical manner, and guide vanes (22) which radially protrude from the conical guide surface (20) and form an acute angle in relation to the rotational axis (y).

La présente invention concerne un dispositif destiné au creusement et à l'évacuation de masses, en particulier de matière de sol, présentant un appareil de creusement qui peut tourner dans un sens de rotation (u) autour d'un axe de rotation (y), et un dispositif d'acheminement longitudinal (18) destiné à l'évacuation de la matière (41) issue du creusement. L'appareil de creusement comprend une roue à ailettes (12, 14) qui présente une surface de guidage (20) conique disposée avec une symétrie de rotation autour de l'axe de rotation (y), et des ailettes de guidage (22) qui dépassent radialement de la face de guidage conique (20) et forment un angle aigu avec l'axe de rotation (y).
