Definitions

  • This presented invention dec ⁇ bes an aggregate for removal of obstacles on and under the surface of the ground whereas its design is also directed to include buried mines and other unexploded munitions, what professionals referres to as UXO's (unexploded ordnance), by using exchangeable toolsectors that when assembled forms circular discs that are in parallel arranged on a, with known technology dnven, central axle in a way that the ground penetrating toolbits working grip concurrently relives each other giving a high working speed and stress loads will be dampened for the purpose of increasing the aggregates reliability and effectiveness
  • the reason for making the invention is to design an aggregate that makes if possible to penetrate the groundsurface and to a certain depth underneath it with the objective to destroy obstacles preferably mines and other munitions.
  • a determining precondition for the inventions design was to reach a technical solution that firstly shall be able to withstand the extensive stress forces in the aggregate when resisting a blast from exploding ammunition. And secondly, if damage occurs that makes the aggregate unusable shall the aggregate with limited transportation being able to quickly repair without the use of more advanced special tools or other resources.
  • the invention is characterised by its method of working on a saw-like way effective in comparison to an aggregate with a milling roller, giving a energy saving penetration of the ground, which leads to the working speed can be increased considerably and the power consumption for the tooldrive decreases.
  • the invention is characterised by only penetrating the ground to the necessary depth required to affect obstacles with a predetermined smallest size leaving surrounding soil untouched between the soil sawing circular discs differing from a milling tool where all soil must pass through the milling tool.
  • the invention is characterised by the soil cultivating components being shaped like circular discs construed of toolsector segments, and by its wedge shape regardless of the cause of the damage easily can be removed and replaced by a new toolsector.
  • the invention is also characterised by the ground working toolbits, which are arranged on the toolsectors peripheral outer boundary, that during its impact against the ground are hitting with the most favourable angle of impact in relation to the nature of the soil.
  • the invention is also characterised by the soil cultivating toolbits, which are attached on the toolsectors, are impacting against the ground with certain time delay between the toolsectors that lie near at hand that reduces stress forces and the risk for vibrations in to the aggregate and by that contributes to increased reliability and reduces the need for repair.
  • Further characteristics for the invention is the device for on and off coupling of the aggregate's central axle by using known technology for coordination of hydraulic or mechanical drive of the central axle and the movement organs on the vehicle mounted carrying arm system, which by parallel movements in side direction in or out from the central axle bearing organ and drive system giving the possibility for quick exchange of the central axle in the frame of the vehicles own resources.

  • FIG. 5 show's example of the inventions application when attached to a carrying vehicle for terrain. Summary of the invention
  • An obstacle removal aggregate 1 is of the required number of toolsectors 2 that is required to achieve a cleared path wider than required by the prime movers width and therefor getting protection for the prime mover and its personnel.
  • the toolsectors 2 are joint together via i.e. triangular shaped point 4 and notch 5 to a circular disc 3 and with preferably attachment elements 16 mounted to for all circular discs common central axle 6.
  • the guiding joints 4 and 5 in the radial direction is not coinciding in parallel with guiding joint 4 and 5 on next in parallel mounted toolsectors 2 but with the intention to more favourable distribute detonation forces between circular discs 3 an thereby reduces the risk for functionally disturbing damage.
  • the central axle 6 supported and driven of a carrying arm system 7 construed partly of preferably one with known technology arranged drive motor 8 and mechanical coupling 9 for driving the central axle 6, partly with known technology designed movement organ 10, that makes it possible with the central axle's 6 centerline via a fully or partly conical shape of the bearing organs in the central axle's 6 outer ends and the supporting axletap's 17 on the carrying arm system 7 in parallel in and out going motion of the carrying arm system 7 to achieve the possibility for quick and easy exchange of the central axle 6.
  • the toolsectors 2 has according to the invention on its peripheral outer boundary with known technology attached holder 11 for attachment of exchangeable toolbits 12 equipped with hard metal edges 13 or equivalent material with satisfactory resistance against wear of actual causes whereas preferably a group of tree holders 11 with toolbits 12 are placed in axial parallel close lying within the toolsector's 2 peripheral outer boundary and longitudinal on the peripheral outer boundary with the required number of groups equalling the need for penetrating depth and considering prime mover 15 wanted driving speed in the clearing direction with the prerequisites set by the ground conditions.
  • Mentioned holders' 11 is attached to the toolsectors 2 in a way that the most favourable angle of attack is achieved in comparison to ground conditions and point of time for respective toolbits 12 penetration against the groundsurface is distributed between close by lying toolsectors 2 and by that counteracting the generation of interacting stress forces and risk for material fatiguing vibrations.
  • the invention has a variant of the central axle 6 with a closed liquid chamber in the longitudinal direction of the axle accessable via a device for filling/emptying and level adjustment 14 of liquid for dampening of vibrations or detonation forces and with organs with known technology for cooling of liquid.

Abstract

L'invention concerne un agrégat (1) dont l'objectif premier est d'éliminer les munitions non explosées d'une surface ou d'une zone se trouvant à une profondeur spécifique sous ladite surface, avec une technologie de travail de type scie économisant l'énergie, de préférence avec un raccordement rapide des organes d'entraînement et de maintien destinés à être raccordés à un véhicule moteur (15), et conçus de manière que la largeur de l'agrégat, dans la direction dégagée présentant une large marge, dégage une surface plus large que celle du véhicule moteur. Les organes centraux de dégagement de l'invention se composent de secteurs d'outils (2), lesquels passent dans des organes de guidage et de fixation de direction radiaux, et lesquels, lorsqu'ils sont reliés à un essieu central (6) entraîné rotatif, constituent des disques circulaires à la périphérie extérieure desquels sont positionnés des outils (12) de travail de la terre interchangeables et orientés. L'invention constitue une solution rendant possible l'échange rapide et simple de secteurs d'outils endommagés (2) et d'outils usés (12).
