Device for clearing landmines

A device for neutralizing a minefield, of the type mounted on a carrier vehicle equipped with at least one support (4) to which a chassis (6) is articulated with the interposition of a pressure actuator (8), the chassis being equipped at its lower end with a plurality of vertical bars (24) the lower ends (26) of which are provided with feet (28) and the upper ends of which are each provided with a piston (15) mounted to slide in a cylinder (13), the various cylinders communicating and being filled with an incompressible fluid subjected to the action of a vibration generator (22) contained in the chassis, characterized in that a mechanical part (10) known as a proportioning device, in which the cylinders (13) used for mounting the pistons (15) arranged at the upper ends of the bars (24) are formed and which incorporates a chamber (14) for placing these cylinders in communication, is mounted to slide between stops (11, 12) in the chassis, parallel to the axes of the cylinders (13), the mechanical part forming a proportioning device (10) being subjected directly to the action of the pressing forces of the actuator (8), via the stops (12) of the chassis.
