Mine clearance system

Abstract

Described is a mine clearance system ( 10 ) comprising a mine clearance vehicle ( 12 ), at the front side of which there is a frontal attachment with a milling roller ( 26 ), the frontal attachment being pivotable about a horizontal axis ( 40 ). A tail attachment forming a mine-seeking apparatus can be provided on the mine clearance vehicle ( 12 ), or a specific mine-seeking vehicle ( 14 ) with such a tail attachment can be arranged after the mine clearance vehicle ( 12 ). That tail attachment or the mine-seeking vehicle ( 14 ) has a second milling roller ( 44 ) which is disposed pivotably about a horizontal axis in order to be able to adjust as desired the height or the depth of penetration into the ground of the second milling roller. A conveyor and sifting device ( 58 ) is arranged after the second milling roller ( 44 ).

         2 . A mine clearance system according to  claim 1  characterised in that the first and/or the second milling roller ( 26 ,  44 ) is provided with radially projecting cutting bit elements ( 28 ,  50 ) which are arranged in a helical configuration in one or more pitch flights on the milling roller peripheral surface ( 30 ,  52 ).  
     
     
         3 . A mine clearance system according to  claim 1  characterised in that the mine clearance vehicle ( 12 ) and/or the mine-seeking vehicle ( 14 ) is formed by a modified armoured or tank vehicle ( 16 ), the turret of which is replaced by a driving cabin ( 18 ).  
     
     
         4 . A mine clearance system according to  claim 3  characterised in that the driving cabin ( 18 ) is supported on shock-absorbing damping elements ( 20 ).  
     
     
         5 . A mine clearance system according to  claim 4  characterised in that a respective damping element ( 20 ) is provided at the bottom in each of the four corners of the driving cabin ( 20 ) which is of rectangular cross-section.  
     
     
         6 . A mine clearance system according to  claim 3  characterised in that a step-down transmission is fitted to the cross-shaft unit of the armoured vehicle ( 16 ) at least for the travel drive, wherein oil motors are used and the oil pump is driven by way of a pump distributor gear unit and an intermediate coupling means by the drive motor of the armoured vehicle ( 16 ).  
     
     
         7 . A mine clearance system according to  claim 3  or  claim 6  characterised in that there is provided a second drive motor which acts by way of a coupling means on a second pump distributor gear unit connected to oil pumps which respectively drive milling rollers.  
     
     
         8 . A mine clearance system according to  claim 7  characterised in that the two drive motors are arranged in vertically superposed relationship.  
     
     
         9 . A mine clearance system according to  claim 6  or  claim 7  characterised in that the oil motors are respectively connected in series.  
     
     
         10 . A mine clearance system according to  claim 6  or  claim 7  characterised in that the oil motors are connected in pairs in series.  
     
     
         11 . A mine clearance system according to one of  claims 6  to  10  characterised in that the coupling means after the drive motor is provided at the input side with a flywheel and at the output side to the pump distributor gear unit has a transition ring.  
     
     
         12 . A mine clearance system according to  claim 3  characterised in that the bottom region of the undercarriage and/or the inner region of the shell structure have additional armouring ( 22 ,  24 ).  
     
     
         13 . A mine clearance system according to one of  claims 1  to  12  characterised in that the first milling roller ( 26 ) and/or the second milling roller ( 44 ) with the associated conveyor and sifting device ( 56 ) are temporarily fixed to the associated or the respectively associated vehicle ( 16 ).
