Abstract
A wear protector system for shielding the leading edge of an earthmoving implement such as a loading bucket includes an arrangement of shrouds which cover the leading edge between the laterally spaced digger teeth. Each shroud has a nose portion that wraps around the leading edge and a rearwardly extending tail portion having an abutment surface that engages an undercut abutment surface of an anchor block that is welded to the bucket. The complementary abutment surfaces retain the tail portion from moving upwardly away from the bucket surface, whereas the shroud is retained from movement forwardly out of engagement with the lip by use of a cotter pin extending transversely through a passage that is formed partially in the tail of the shroud and partially in the anchor.
Claims10
A wear protector system for shielding from wear a portion of a leading edge of an earthmoving implement, said system including:
- an anchor for fixed welded attachment to a surface of said implement at a predetermined location rearwardly of said leading edge, said anchor comprising a block having a bottom surface for attachment to said implement surface, an undercut transverse forward first abutment surface, and an upper surface;
- and
- a shroud having a U-shaped nose and a rearwardly extending tail, said tail defining a transverse rearwardly facing second abutment surface that is complementary to said first abutment surface, said anchor and said shroud being configured to interengage when said anchor is fixed to the implement at said location such that the nose of the shroud lies against and extends around said leading edge;
- said anchor and said shroud having respective complementary channels, which, when said anchor and shroud are interengaged, together define a transverse passageway;
- through which a tapered cotter pin can be inserted to retain said shroud in engagement with said anchor and with the leading edge of the implement.
