Method of increasing life of tillage equipment working tools. RU patent 2443524.

FIELD: process engineering.

SUBSTANCE: invention may be used in reconditioning tillage equipment working tool surfaces. Rolls are welded on perpendicular to axis of beam-like wear, spaced apart for 20-30 mm to produce spacing between them. Roll height does not exceed the level of working surface of the part being reclaimed. Said spacing is filled in operation by soil that acts as anti-abrasive medium.

EFFECT: higher resistance to abrasive wear.

Method of reconditioning center hoes of tillage row-crop cultivators / 2443523
Invention may be used in reconditioning tillage equipment working tool surfaces. Metal stock is formed in point area and along blade length by electric arc deposition by electrode to produce buffer stock of built-up metal that allows recovery of rated sizes of hoes. Building-up may be carried out both manually and mechanically by electric arc deposition. Hoe is drawn out by hot deformation using forming mandrel that follows hoe point and blade shape. Further hardening is performed by quenching. In buffer metal building-up and drawing-out, thermal processes occur to bring about structural components that increase hardness of reconditioned zone and facilitate increasing resistance to abrasive wear.
