FIELD: process engineering.
SUBSTANCE: invention relates to machine building and repair of agricultural machinery, particularly, to recovery of plowshares tips. In compliance with this invention, steel cover element is cut out to be welded to worn-out surface of plowshare front part. Also, reinforcing rolls are welded on surface of possible areas wherein star wear is expected. Said steel cover element represents a pre-sharpened plate with thickness that corresponds to that of recovered plate, but not over 6 mm, that repeats geometry of chisel-type share which is cut out from hardened strip of secondary steel. Note here that width of the plate extension corresponds to shape chisel width. Welding is carried out on arranging plate lower edge parallel to plow blade, while front edge is aligned with landward edge shape.
EFFECT: simplified recovery, reducing probability of occurrence on deformations and fractures in 5-6 mm-thick plowshares.
