ADAPTER FOR ATTACHMENT OF TOOL TO EXCAVATING MACHINE WORKING ELEMENT (EMBODIMENTS) Russian patent published in 2024 - IPC E02F9/28 

FIELD: construction.

SUBSTANCE: group of inventions relates to assemblies in the form of a working member, such as assemblies in the form of a bucket, used by excavation, mining, construction equipment, etc. Adapter comprises a main portion comprising a protruding portion that is configured to facilitate attachment of the tool, a first bifurcated arm that comprises a pair of side surfaces of the first arm, second arm comprises a pair of side surfaces of the second arm and a connecting part which connects the arms and the projecting part together. First and second arms and connecting part define a horizontal recess, which has a closed end and an open end, wherein horizontal recess defines direction of assembly on working tool while first bifurcated arm comprises first inclined part arranged in vertical recess. At that, the first inclined part forms the first acute angle with the assembly direction in range from 20 degrees to 40 degrees, and the first bifurcated arm defines a recess for receiving a key, which is located in front of the hole in the horizontal direction. At that, key recess is located on, at least, one of two side surfaces of first arm to define open end facing in horizontal direction to extending part. At that, connecting part additionally comprises a protrusion located on the closed end of the horizontal recess, wherein the protrusion extends in the assembly direction and in the transverse direction near the first side surface of the connecting part and near the second side surface of the connecting part. Horizontal recess defines the vertical height of the gap for the staple, and the projection comprises a flat middle portion enclosed on the side by a first arched portion and a second arched portion, flat middle part, which determines the width of the transverse middle part and the vertical height of the transverse middle part, and the vertical height of the transverse middle part is in range of 0.7 to 0.75 of the vertical height of the gap for the bracket.

EFFECT: higher strength of adapter.
