PROTECTIVE SEGMENT OF DRAGLINE BUCKET EDGE Russian patent published in 2019 - IPC E02F9/28 

FIELD: instrument engineering.

SUBSTANCE: group of inventions relates to replaceable wear parts for protection of the leading edge of the earthmoving equipment. Dragline bucket edge assembly contains a dragline bucket edge containing at least one vertical element with a protrusion and a protective segment. Protective segment comprises a first side wall having a first abutment surface, a second side wall, having a second bearing surface and a fastening section adapted for connection with a locking device on the edge of the dragline bucket, and a central wall, having a third bearing surface with a hole. In this case, the central wall connects the first side wall and the second side wall so that the first, the second and third support surfaces form a chute for receiving a portion of at least one vertical element. Protrusion is made with the possibility of entry into the hole of the support surface of the central wall.

EFFECT: technical result – prevention of wear of the edge of the dragline bucket and elimination of the deformation of the mechanical fastening, simplification of removing the protective elements.
