Abstract
A hand-held, self-contained motor-driven trenching device (100) for cutting a slit or trench within a substrate is based on a chain-saw motor unit together with a purpose-built attachment. An unmodified chain-saw drive unit provides both motive force and a holder, although purpose-built units may employ other forms of motive power. A chain-driven reduction drive matches the chain-saw drive sprocket (101) speed to a suitable toothed digging chain cutting speed; the reduction drive being coupled to a sprocket wheel (102) aligned at one end of a sturdy, hardened steel blade (106) over which a heavy roller chain (200) bearing soil-cutting teeth (203) is pulled. The resulting trench is about 30-35 mm wide, up to 1 meter deep, and of indefinite length. The invention provides an optimized solution to a need for burying narrow cables, fiber-optic conduits, water pipes, and the like well into the ground.
