ABSTRACT:
A digging machine for planing a road. The machine has a massive main frame supported by large endless tracks. An elongated digging member has spaced shafts located at the opposed ends thereof. One of the shafts pivotally supports the digging member from the rear end of the main frame, while the other shaft rotatably supports a digging head. The digging head is rotated by spaced, endless chains that are driven by sprockets located on the pivot shaft and thereby rotates sprockets located on the other shaft. Cutter plates are supported by the spaced chains and form an endless cutter member. Opposed drums are mounted on opposed marginal ends of the driven shaft and are rotated by the driven sprockets. The drum surface has flights formed thereon. Digging teeth are mounted on the outer periphery of the flights and cutter plates. The digging head can be made as wide as the vehicle and thereby excavates adjacent to a vertical wall. The excavated material is conveyed by the endless cutter member up to a lateral conveyor where the material is deposited to one side of the digging machine.
