Abstract
Disclosed herein is a device for orienting a drilling auger disposed on and powered by a vehicle defined by a lower frame member carried by the vehicle, an upper frame member pivoted to the lower frame member for rotation about an axis, and an auger supporting framework pivoted to the upper framework for rotation about a second axis orthogonal to the first axis in which the rotation is controlled by hydraulic cylinders extending between the lower and upper frame members, and between the upper frame member and the auger supporting framework, respectively. The auger itself is driven by a power take-off on the vehicle in a preferred form which in conjunction with the preceeding structure allows the auger to address the earth in which the hole is to be drilled in substantially any angle above the surface of the earth.
Claims7
A device including a drilling auger removably attachable to and powered by a tractor type vehicle having power takeoffs comprising in combination:
- a lower frame member carried by the vehicle,
- an upper frame member pivoted to said lower frame member having first means for controlled rotation about a first axis,
- and a supporting framework carrying the auger and pivoted to said upper framework having second means for controlled rotation about a second axis orthogonal to said first axis whereby the auger is suitably supported and able to bore into earth at substantially any angle relative to a plane defined by the earth wherein said lower frame member forms substantially an isosceles triangle when viewed in a top plan view having truncated apices and said first axis extends from a midportion of a base of said lower frame member to an apex where two equal-length sides meet in which said truncated apices have outer faces which attach to the vehicle including:
- projecting pins on two apices proximate to said base and a plate bolted onto the remaining apex, said plate having a tongue-shaped snout for connection with said vehicle, said lower frame member disposed in a horizontal plane
