Cutting tooth

Abstract

The invention relates to a cutting tooth for working the soil having a base area for arrangement in a cutting tooth holder and a head area with at least one cutter for removing soil material. The head area has a plate-shaped cutting wing arrangement, the wings of which project laterally with respect to the base area.

1 . Cutting tooth for working the soil having
 a base area for arrangement in a cutting tooth holder and   a head area with at least one cutter for removing soil material,   wherein the head area has a plate-shaped cutting wing arrangement, the wings of which project laterally with respect to the base area,   
       wherein
 the cutting wing arrangement has a V-shaped cutting edge, from the apex of which a central cutting edge which runs in a center area of the cutting tooth transversely to the cutting edge extends in the direction of the base area and 
 in that below the cutting wing arrangement and laterally of the central cutting edge a curved guide surface is designed for displacing soil material in the direction of the base area and into a lateral area. 
 
     
     
         2 . Cutting tooth according to  claim 1 ,
 wherein   together with the base area the cutting wing arrangement forms a T-shape.   
     
     
         3 . Cutting tooth according to  claim 1 ,
 wherein   the cutting edge has a linear-shaped design.   
     
     
         4 . Cutting tooth according to  claim 1 ,
 wherein   the cutting edge has an arrow-shaped design.   
     
     
         5 . Cutting tooth according to  claim 4 ,
 wherein   the apex of the cutting edge forms an uppermost point of the cutting tooth.   
     
     
         6 . Cutting tooth according to  claim 4 ,
 wherein   starting from the cutting edge the wings slope down rearwards.   
     
     
         7 . Cutting tooth according to  claim 1 ,
 wherein   the wings have a curved upper side.   
     
     
         8 . Cutting tooth according to  claim 1 ,
 wherein   an upper side of the wings slopes laterally downwards in the direction of the base area.   
     
     
         9 . Cutting tooth according to  claim 1 ,
 wherein   an upper side of the wings has a concave curvature in the cutting direction.   
     
     
         10 . Cutting tooth according to  claim 1 ,
 wherein   the cutting edge projects upwards with respect to an upper side of the wings.   
     
     
         11 . Cutting tooth according to  claim 1 ,
 wherein   the cutting edge projects with respect to the base area in the cutting direction.   
     
     
         12 . Cutting tooth according to  claim 1 ,
 wherein   the base area has a U-shaped holding groove.   
     
     
         13 . Cutting tooth according to  claim 12 ,
 wherein   the holding groove extends into a rearward area of the plate-shaped cutting wing arrangement.
