FIELD: agriculture.SUBSTANCE: invention relates to agricultural machine building, particularly to sowing machines. Ploughshare includes a vertical disc knife installed on brackets, ensuring matching of traction force direction with ploughshare motion direction, a seed duct and fertiliser. To sides of disc knife are flanges for restriction of penetration of ploughshare. Brackets are fixed by bolts to a post and have a bend at ends of flanges. Front part of post has a tapering transitioning into lower part of parabolic curve, coupled with a wedge-like toe. Seed duct is mounted behind post. To side walls of post with using bolts with countersunk head-closing hoes are fixed for seeding and cheek-ditchers, between which fertiliser. Rear parts of cheek-ditchers are bent to cover fertiliser.EFFECT: such design will allow to ensure appearance of stable even shoots due to combination of operations of seeds sowing and application of fertilisers with formation of a soil layer between them.1 cl, 3 dwg |
