    • 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).
    • 一种用于挖掘和材料排出装置,特别是土壤材料制成,包括一绕旋转轴线(Y)可转动的挖掘作业装置和一个纵向传送装置(18),用于在旋转方向(u)的去除挖掘材料(41)的。 挖掘设备包括布置成与旋转对称的围绕旋转轴线(Y),锥形路由区域(20)和锥形LEIT(20)和相对于所述旋转轴线(Y)的径向凸出表面的叶轮(12,14)以锐角形成 导向叶片(22)。
