Abstract
A digging tooth for a bucket having a concave top surface and a convex bottom surface which intersect forming a forward cutting edge. Sidewalls connect the two surfaces and are concave having a moldboard shape. The rear portion of the tooth is provided with a mounting assembly for mounting it to a bucket. The bottom surface continuously diverges from the forward cutting edge to the rear portion; whereas the top surface first converges then diverges from the forward cutting edge to the rear portion.
Claims1
A digging tooth for a digging bucket, comprising
- a top concave surface;
- a bottom convex surface intersecting the top surface to form a forward cutting edge;
- two moldboard sidewalls extending between the concave top surface and the convex bottom surface, the top surface and the two sidewalls defining two concave top-side edges, the bottom surface and the two sidewalls defining two concave bottom-side edges;
- and
- a rear portion extending between the concave top surface, the convex bottom surface and the two sidewalls, the rear portion being provided with mounting means for mounting said digging tooth on a digging bucket, wherein the bottom surface proceeding from the forward cutting edge to the rear portion first converges than diverges, and the top surface proceeding from the forward cutting edge to the rear portion continuously diverges.
