WORKING PART SECTION FOR KNIFE IN BULLDOZER BLADE ASSEMBLY IN MOUNTED SYSTEM, KNIFE FOR BULLDOZER BLADE IN MOUNTED SYSTEM, AND BULLDOZER BLADE ASSEMBLY Russian patent published in 2022 - IPC E02F3/815 E02F9/28 

FIELD: soil-shifting.

SUBSTANCE: group of inventions relates to cutting edges with bolted mounting for bulldozer blade assemblies, in particular to a knife for a bulldozer blade assembly. A working part section for the knife in the bulldozer blade assembly of a mounted system contains: an elongated inner blade and an outer angular knife. The elongated inner blade contains a cutting surface passing between the front edge and the rear edge, an inner installation surface located opposite to the cutting surface, as well as a set of mounting holes passing between the cutting surface and the installation surface for placing the set of mounting elements to fix the working part section to the installation surface of the bulldozer blade. The outer angular knife contains a front surface adjacent to the cutting surface of the elongated inner blade, passing between the front edge and the rear edge, as well as an outer installation surface located opposite to the front surface and in one plane with the inner installation surface. In this case, the elongated inner blade has a linear profile of the front edge, and the outer angular knife is made as a single whole with the elongated inner blade and has a non-linear profile of the front edge that passes to the specified linear profile of the front edge of the elongated blade.

EFFECT: providing more rapid and easy forward movement of material by the blade.
