Mobile excavator for narrow trenches in ground - has excavating wheel and high speed wheel ejecting soil sideways

摘要

The excavator makes a long narrow trench of a specified cross section into the ground. On the excavator frame, is fitted a rotating excavation wheel with scoops. The excavated soil is ejected sideways preventing obstruction of the excavator. The arrangement has an ejecting wheel (14) in the upper part of the ramp (11). This wheel rotates about its axis (19) for throwing soil excavated by the excavating scoop wheel sideways. The rotating speed of the ejecting wheel (14) is much higher than the rotating speed of the excavating scoop vessel (4), which feeds excavated soil to the ejecting wheel.
