GROUND WORKING IMPLEMENT INCLUDING A SHANK AND A TIP

摘要

A shank (10) and replaceable tip (11) of a ground working implement are defined from flat plate which is cut by laser or similar or is stamped to provide interconnecting elements (40) between the replaceable tip (11) and the lower end of the shank (10). At the lower end of the shank (10) is provided a pocket (41) defined by a recess cut into the lower end and a pair of plates (50, 51) welded on respective sides of the flat plate so that the projection of the replaceable tip (11) extends into the pocket (41) to hold the tip (11) in place. This allows a rugged construction of the tip (11) and various designs of tip (11) can be manufactured simply by reprogramming the cutting process. A guide surface (60) is mounted on the front plate of the shank (10) with that guide surface (60) defining a channel member with a leading edge increasing in radius of curvature from the lower end of the shank (10) upwardly to a top of the guide surface (60) spaced upwardly from the ground. This increase in width of the guide surface assists in discarding trash.
