HIGH-PERFORMANCE WEARING ELEMENT OF WORKING TOOLS Russian patent published in 2019 - IPC E02F3/815 E02F9/28 

FIELD: displacement and excavation of soil.

SUBSTANCE: invention relates to tools for earthworks on buckets, knives and other working tools used in mining and construction equipment. Wear element contains the body having the following parts: anterior, posterior, upper, lower, inner side and outer side, profiled upper front surface and profiled lower front surface. Cutting edge is made at least along the lower interface between the front part and the bottom part. Profiled upper front surface is made on the front part. In this case, the profiled upper front surface extends between the upper edge located along the upper interface between the front part and the upper part, the edge of the outer side, which is located along the border of the outer side between the front part and the outer side part, the ridge located on the front part, and the wedge-shaped edge, which is located along the lower interface between the part of the outer side and the cutting edge. Profiled lower front surface is made on the front of the body, which is adjacent to the profiled upper front surface. Profiled bottom front surface is made between the edge of the inner side, which is located along the boundary between the inner side between the front part, the inner side part, the cutting edge and the ridge.

EFFECT: improved cutting edge system, increased efficiency of ground engaging equipment and increased productivity.
