    • The present invention discloses a method and apparatus for excavating material from a mining or reclamation operation, and is generally considered useful in open cast mining operations. The apparatus has a first conveyor and a second conveyor attached to a chassis. The first conveyor is fitted with a material remover such as a excavator bucket on a first end. Material discharges from the first conveyor onto a second conveyor which is generally longitudinally aligned with the first conveyor and has a material receiving point located elevationally below the discharge point of the first conveyor. The first conveyor is moved in a forward direction by a crowder which consists of motion generally along the coincident longitudinal axes of the two conveyors. The first end of the first conveyor which is fitted with the excavating bucket is elevationally moved by virtue of a boom and cable configuration.
    • 本发明公开了一种从采矿或开采作业挖掘材料的方法和装置,在露天采矿作业中通常被认为是有用的。 该设备具有第一输送机和附接到底盘的第二输送机。 第一输送机在第一端装有诸如挖掘机铲斗的材料去除器。 材料从第一输送机排放到第二输送机上,该第二输送机大体上与第一输送机纵向对齐,并且具有位于第一输送机排放点正下方的材料接收点。 第一输送机由向前的方向移动,该挤压机主要由沿着两个输送机的重合纵轴的运动组成。 装有挖掘铲斗的第一输送机的第一端由于悬臂和电缆的构型而正向移动。
