FIELD: machine building.
SUBSTANCE: invention relates to cutting bucket of earthmover machine bucket. Bucket cutting edge for earthmoving machines comprises a front cutting edge provided with a plurality of protrusions for receiving a plurality of teeth, a plurality of front recesses located between said projections to accommodate a plurality of front protective members, and a plurality of tensile elements for distributing stress generated during application of the ladle. Elastic elements are arranged between said projections behind said front recesses. At the same time internal elements working for tension, and external elements working for tension have different shapes.
EFFECT: technical result is optimization of distribution of stresses arising when using machine for excavation, increased resistance of cutting edge of bucket to fatigue loads, reduced number of repairs and works on recovery of bucket operating state.
