Abstract
The mine and explosive clearing machine and implement includes a long reach excavator modified with a float-type hydraulic valve for vertical control of the arm. The mine and explosive clearing implement is installed on the distal end of the arm in place of a conventional tool. The implement includes a frame having multiple tilling blades separated by shoes defining blade penetration depth. Multiple cables are pivotally attached to the rear of the frame, each cable having another tilling blade at its distal end and a brush blade opposite the tilling blade. The cables may be inverted to orient either blade downward. The prime mover of the excavator is positioned and the arm extended rearward. The implement is then lowered and dragged forward toward the prime mover so that the blades engage the surface to dislodge and/or detonate explosives at a safe distance from the prime mover.
