MODULAR EARTHMOVING TOOL SYSTEM Russian patent published in 2021 - IPC E02F9/28 E02F9/24 E02F3/40 

FIELD: earthmoving equipment.

SUBSTANCE: group of inventions relates to a mining excavator, more specifically to an earthmoving tool system for a bucket. The tool system contains: a modular adapter made with the possibility of partial insertion to any one hole from a set of holes in a cutting edge of the bucket along the insertion axes, a fixation system containing fastening means made with the possibility of extending at least partially in a hole and connecting the adapter to the cutting edge, and a separate wear-resistant component made with the possibility of attachment to the inner surface of the bucket. The adapter is made with the possibility of a removable connection to the cutting edge, and it contains the first conical section made with the possibility of extending in a hole and the second section made with the possibility of extending from a hole. The hole is the first hole, wherein the adapter contains the second hole extending at least partially through the adapter along the axes perpendicular to the insertion axes. The second hole is made in such a way that it can be aligned with the third hole in the cutting edge. The third hole is made with the possibility of intersection with the first hole and can be aligned with the second hole, when the adapter is connected to the cutting edge, while the third hole is made with the possibility of passing through the separate wear-resistant component.

EFFECT: technical result is protection of material from wearing along the upper and lower parts of the cutting edge.
