Abstract
A system for clearing anti-personnel mines includes a vehicle, a blast shd on the front of the vehicle, and arms pivoted to the blast shield. A roller wheel subassembly is connected to the arms by cables or chains. Cross members fastened diagonally between the arms minimize side to side swing of the arms on the blast shield while allowing the arms to swing up and down relative to each other. The vehicle has a boom for lifting the arms and roller wheel subassembly. The arms connect to the boom by another chain or cable that slides through an eye on the boom so that the chain or cable accommodates relative vertical swing of the arms. The roller wheel subassembly has an axle and roller wheels on the axle, the inner diameter of the roller wheels being greater than the axle's diameter. Annular spacers on the axle alternate with the wheels, the spacer diameters being larger than the wheels' inner diameters but smaller than the wheels' outer diameters. The wheels and spacers move independently of one another rotationally and radially relative to the axle.
