ADAPTER FOR FASTENING THE BIT TO THE WORKING TOOL (VARIANTS) AND ASSEMBLY Russian patent published in 2023 - IPC E02F9/28 

FIELD: earth-moving tools.

SUBSTANCE: group of inventions relates to earth-moving tools used in buckets, dumps and other working tools used in mining and construction equipment. The bit adapter for attaching the bit to the work tool comprises: a base, a work tool mounting part extending from the base and capable of being attached to the work tool, and a bit mounting part. The base contains a protruding surface and a fixation surface, which face each other and are located with an offset in the transverse direction relative to each other in the cross section of the base in such a way that a mounting groove is formed between them. The mounting part of the crown extends from the base in the opposite direction relative to the mounting part of the working tool and contains a mounting head, the first fastening element and the second fastening element. The mounting head contains the end face of the base and the far end. The end of the base is connected to the base. The mounting cap extends from the end of the base to the far end along the longitudinal axis of the cap. The mounting head contains the first end surface and the second end surface, converging towards each other in the direction from the end of the base to the distal end along the vertical axis of the head, perpendicular to the longitudinal axis of the head. The mounting head contains the first side surface of the head and the second side surface of the head, wherein the first side surface of the head and the second side surface of the head are located at a distance from each other along the transverse axis of the head, while the transverse axis of the head is perpendicular to the longitudinal axis of the head and the vertical axis of the head. The first side surface of the head and the second side surface of the head extend between the first end surface and the second end surface. In this case, the first fastening element extends from the first side surface of the head along the first axis of the fastening element, and the second fastening element extends from the second side surface of the head along the second axis of the fastening element.

EFFECT: securing the wear-resistant cover on the base of the adapter.
