PLOUGHSHARE FOR POUR PLATE SEEDING Russian patent published in 2016 - IPC A01C7/20 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the agricultural industry, in particular to the coulter sections used in sowing machines, producing straight-seeding crops in exactly the predetermined depth. Shovel section includes a rotary cutter in the form of a flat ring with a cutting edge at the outer diameter. Disk knife is provided with a furrower, grain spout. On a flat disk mounted flange in the form of hollow cylinders. Diameter of the circular cutter accepted condition for a given depth of seeds. Disc is mounted on the knife rack furrower with bracket. Furrower has bottom grooves shaper predetermined profile. Front cutting edge formed furrower parabolic. Back wall of the vas deferens is fixed furrower having cut back wall and disposed along the centerline of the groove formed by groove shaper. Behind the furrower a sealing roller is installed in the form of opposing the established small bases of the truncated cones, width sealing-covering rollers wider than the grooves formed by a notch generator on the magnitude of the collapse of the side edge of the groove and is equal to 15…20 mm. For sealing-covering rollers with chains fixed trail-harrow.
