ABSTRACT:
The trenching machine of the present invention comprises a support frame, a continuous member either of the wheel or chain type having a plurality of excavating members mounted thereon, mounting means retentively movably mounting the continuous member to the frame, for movement of the excavating members in a continuous path, the mounting means comprising at least two rotatable wheels mounted to said frame for rotation and positioned as to engage the continuous member for rotatable retentive engagement therewith, at least one of the wheels being movable toward and away from the other of the wheels, and power means for moving the movable wheel away from the other wheel so that the wheels may be adjusted to take up the slack between them and the continuous member. The excavating members are of semi-circular construction, some of the members facing in one direction and the other of the members facing in the opposite direction so that each excavating member excavates approximately half of the trench. A shoe assembly is mounted rearwardly of the excavating members and includes a pair of spaced apart shoe casing plates which are flexible adjacent their rearward ends so as to conform to the trench even when the trenching device turns to cut a curved trench. An elongated shoe is mounted to the shoe assembly adjacent the lower end thereof and includes power means connected thereto for causing pivotal movement of the shoe about a horizontal axis so as to permit selective pivotal adjustment of the attitude of the shoe.
