METHOD FOR HARDENING CULTIVATOR SHEETS BY DOUBLE-SIDED SURFACE Russian patent published in 2022 - IPC B23P6/00 B23K9/04 A01B15/04 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering and can be used in the manufacture and restoration of the working bodies of cultivators subjected to abrasive wear. In the method, wear-resistant material is applied in the surfacing zones in the form of hemispherical bodies fused into the material of the cultivator share from its upper side - bodies of a hemispherical shape with a diameter equal to the thickness of the share base, placing their centers along the shares' blades, and in its bow part along arcuate reinforcement lines. A wear-resistant material is applied to the surface of the base of the working part of the cultivator paw from its lower side in the form of ellipsoidal bodies, while the ellipsoidal bodies are applied to the working surface in the fore part of the paw and in the middle part of the paw wings in two rows, placing their centers along arcuate lines of reinforcement with a distance between centers equal to the thickness of the base of the paw, and a distance between rows equal to this thickness.

EFFECT: invention makes it possible to increase the durability of cultivator paws and preserve the original geometric shape of the working parts during their operation.
