Definitions

  • the invention relates to mine clearing apparatus and in particular, apparatus for clearing mines which are buried.
  • mine clearing apparatus is operated by exerting a pressure or creating an impact on the surface of the ground which is to be cleared, the pressure exerted or the impact being sufficient to detonate any mines.
  • this conventional apparatus has the disadvantage that it may not detonate mines which are buried below the surface. Hence, such buried mines if subsequently exposed could pose a potentially lethal hazard on ground which it is believed is clear of mines.
  • apparatus for clearing mines comprises a support, a first impact device mounted on the support and a ground engaging member mounted on the support wherein the ground engaging member is adapted to extend below the surface of ground being cleared so that when the support is moved across the surface of the ground, the ground engaging member exposess mines in its path and the first impact device generates an impact on the exposed mines.
  • the apparatus further comprises a second impact device which generates an impact on the surface of the ground.
  • the second impact device is mounted on the support so that it precedes the first impact device when the support is moved across the surface of the ground in use.
  • the first impact device precedes the ground engaging member as the support is moved across * the surface of the ground.
  • the apparatus further comprises means to vary the height of the impact devices relative to each other and typically, this could comprise a hydraulic mechanism.
  • the first impact device and/or the second impact device comprises a flail mechanism which is rotationally mounted on the support and typically, the axis of rotation of the flail mechanism is substantially perpendicular to the direction of movement of the support across the surface of the ground in use.

  • the transport device is armoured.
  • the first flail mechanism comprises a number of case hardened leaf springs mounted on a central axle and which extend radially when the flail mechanism is operating to form the individual flails.

  • the tine sections 18 are formed from case hardened steel and typically, where the flail rotors 3, 4 have a width of 14 feet then thirteen ground engaging members 5 are positioned in a linear array on the grid 6 so that the plane of the array is substantially parallel to the axes of rotation of the flail rotors 3, 4.

  • the apparatus 1 is mounted on the bulldozer 30 in place of the conventional bulldozer blade and is preferably mounted to the "C"-frame of the bulldozer by quick release pins.
  • the apparatus 1 can then be raised or lowered on the bulldozer 30 via arms 31 and hydraulic pistons 32 (only one shown) which are mounted on either side of the bulldozer 30 and form the "C"-frame.
  • a powerpac 33 is also preferably provided and this is typically a Cummings NT 855 P400 6 cylinder, water cooled four stroke diesel engine of 400 hp.
  • the engine drives two 6600 HD Commercial Hydraulic Pumps to supply hydraulic power to the flails 3 , 4 and to the ground engaging members 5.
  • the powerpack 33 as shown in Fig.2 attaches to the rear of the bulldozer 30 by quick release pins (not shown).
  • the apparatus 1 is lowered so that the striking tips 13 of the flail rotor 3 touch the surface of the ground to be cleared and the arms 8 are then lowered via the hydraulic pistons 10 until the striking tips 16 of the flail rotor 4 also touch the surface of the ground to be cleared.
  • Rotation of the flail rotors 3, 4 is then commenced by an operator and as the bulldozer 30 moves forward, the tine sections 18 of the ground engaging members 5 are lowered using the hydraulic pistons 19 until they are located at a suitable depth in the ground being cleared.
  • the flail 4 first clears the ground by detonating or disrupting surface laid or normally buried anti-tank and anti-personnel mines.
  • the tine sections 18 then lift any deeply buried (up to 60 cm) normally inaccessible mines for destruction by the flail rotor 3. If the flail rotor 3 does not destroy mines which have been lifted by the tine sections 18 then the mines are flipped forward by the flail rotor 3 and the tine sections 18 into the main rotor 4 for destruction.
  • the tine sections 18 are designed to clear a path by lifting mines for destruction without pushing them outside the cleared path of the apparatus 1. If the mines are pushed outside the clear path then they would of course still remain a hazard in this uncleared area.
  • the ground engaging members 5 are separated from each other so that mines cannot pass between the ground engaging members 5 and go under the bulldozer 30.
  • the tine sections 18 will dig as deep as 60 cm and, if required the operator can manually alter the individual depth of each tine section. This is particularly suitable on verges, etc where one side of the vehicle may be on hard ground and the other on soft, or where there are deep rots. In areas where digging is not required the tine sections can be retracted to remain clear of the ground.
  • the pivot points 20 and the biasing means 21 connecting each ground engaging member 5 to the grid 6 permit pivoting movement of each member 5 individually about its respective pivot point 20.
  • the section 18 and body member 17 will pivot about the pivot point 20 to enable the tine section 18 to clear the obstruction.
  • the biasing means 21 then returns the member 5 to the vertical position after the section 18 has moved past the obstruction.

Abstract

On décrit un appareil de déminage comportant un support (2) sur lequel est monté un premier dispositif d'impact (3) se présentant sous la forme typique d'un rotor à fléaux. Un certain nombre d'éléments s'enfonçant dans le sol sont également montés sur le support (2). Chacun de ces éléments s'enfonçant dans le sol est adapté pour pénétrer dans le sol devant être déminé de telle sorte que lorsque le support (2) se déplace au-dessus de celui-ci, les éléments s'enfonçant dans le sol (5) exposent les mines sur leur chemin. Le premier dispositif d'impact (3) génère alors un impact qui est dirigé sur les mines exposées. De préférence, l'appareil comprend également un deuxième dispositif d'impact (4) qui se présente sous la forme d'un rotor à fléaux. Le deuxième dispositif d'impact (4) est destiné principalement à la destruction de mines en surface classiques, tandis que les éléments s'enfonçant dans le sol (5) ainsi que le premier dispositif d'impact (3) sont destinés principalement à la destruction de mines enterrées.
