ABSTRACT:
A mineplough which is designed to be resilient to exploding mines comprises one or more blades set at an angle to the general direction of movement of the plough so as to deflect lifted earth to one or both sides of the plough and having tines arranged so as to lift earth ahead of the blade in the direction of travel thereof, depth control means for controlling the depth of cut of the tines and at least two linkages to connect the blade to a suitable carrier vehicle for the mineplough. The blade is comprised of a number of intersecting strong metal plates whose planes lie substantially parallel to the direction of travel of the mineplough and which define relatively narrow open channels therebetween so as to allow venting of any explosion caused by a mine exploding in contact with the blade. The blade may be faced with a relatively thin metal or plastics sheet to absorb some of the force of any explosion and further protection is provided by the fact that each linkage contains at least one crushable element capable of absorbing blast energy.
