CULTIVATOR A-BLADE FOR SOWING OF SEEDS Russian patent published in 2018 - IPC A01C7/20 A01B35/20 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine building, in particular to the intended for seeding cultivating tools. On the cultivator's A-blade mounting post front side in the area of the most likely wear abrasion-resistant dispersion-hardened coating with a thickness of up to 2.5 mm is applied. Coating material consists of an epoxy base (50 parts by weight), which comprises 100 parts by weight of ED-20 epoxy resin and 10 parts by weight of a hardener (polyethylene polyamine), and a filler (50 parts by weight) of granite chips with a dispersion of 2-2.5 mm. To ensure the coating adhesion strength to the A-blade material at the area of the composite formation, grooves are made having a depth of 2 mm, a width of 2 mm, a length of 40 mm and a pitch of 15 mm.

EFFECT: such design solution provides an increase in the cultivator's A-blade post service life and increase in the resistance to abrasive wear.
