FIELD: digging devices.
SUBSTANCE: group of inventions relates to digging devices connected to excavators for laying trenches or removing asphalt layers, etc. The digging device for a working machine contains a case including a connecting part for connecting to the working machine and limiting the first chamber, in which a device digging tool rotating around the axis (R) and a self-leveling case are partially placed. The self-leveling case contains a pair of support skids in contact with the treated surface (Z), and it is freely installed with the possibility of rotation relatively to the case so that the connecting part is capable of occupying different angular positions relatively to support skids. The self-leveling case contains at least one pair of transverse walls offset in the axial direction along the axis of rotation (R) and rigidly connected by a pair of longitudinal walls of this case to form a box-like structure, in which the digging tool is placed, protruding frontally to support skids. The case is mechanically connected to the self-leveling case with the possibility of uniform pressure application to transverse walls and support skids.
EFFECT: providing high strength, allowing even transfer of forces arising during unearthing to mechanical components to reduce the wear effect.
