DISC SOWING SECTION Russian patent published in 2015 - IPC A01B49/06 A01C7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural engineering, in particular to devices for planting grain crops with simultaneous local application of mineral fertilisers, and can be used on seed-fertiliser seeders. The disc sowing section comprises the L-shaped rack (1) and the central circular blade (4) consequently fixed to its lower rear part, the A-hoe (5) with a fertiliser tube (6), the disc sowing blades (14) with fertiliser-seed tubes (16), the drawbar (18), the roller (17). The rear lower part of the L-shaped rack (1) on its both sides the sleeves with through holes of square cross section are rigidly secured offset relative to each other. Inside the sleeves the brackets are mounted. The brackets are provided with screws (9) with annular grooves near the heads. The stops (10) are mounted in the annular grooves. The stops (10) are rigidly fixed to the L-shaped rack (1). The opposite ends of the brackets in the vertical direction the spline bushings are rigidly fixed. In the spline bushings the pins with splined ends are inserted. The pins with splined ends are secured in the perpendicular direction by axes with the disc sowing blades mounted on them.

EFFECT: constructive solution is aimed at ensuring adjustment of the inter-row spacing width and angles of attack of the sowing disc blades.
