Knee link flail (KLF) system

Abstract

A knee link flail system for neutralization of landmines consisting of a rotatable shaft mounted on a carriage with flat structures attached perpendicular to the shaft at predetermined intervals. A plurality of first legs are connected to outer edges of the flat structures via first rotatable connections. A plurality of second legs, each being connected to an outer end of an associated first leg via a rotatable connection. A hammer mass is attached to an outer end of each second leg that impacts against a soil's surface upon rotation of the rotatable shaft.

1 . A knee link flail system comprises a rotable shaft mounted horizontally on a carriage with a plurality of flat structures attached to and perpendicular to the rotatable shaft which structures are spaced at predetermined intervals along the rotatable shaft, a plurality of first legs being connected to outer edges of said structures via first rotatable connections, a plurality of second legs each of which are connected to an outer end of an associated first leg via a rotatable connection, a hammer mass being attached to outer ends of each of the second legs to impact against a soil's surface upon rotation of said rotatable shaft.  
     
     
         2 . A knee link flail system as defined in  claim 1 , wherein each flat structure is a disc.  
     
     
         3 . A knee link flail system as defined in  claim 2 , wherein the length ratio of the first and second legs are 1:1.  
     
     
         4 . A knee link flail system as defined in  claim 2 , wherein the length ratio of the first and second legs are 1:0.5.  
     
     
         5 . A knee link flail system as defined in  claim 3 , wherein a total link length of the legs is 345 mm.  
     
     
         6 . A knee link flail system as defined in  claim 4 , wherein a total link length of the legs are 445 mm.
