SOWING SECTION Russian patent published in 2011 - IPC A01C7/00 

FIELD: agriculture.

SUBSTANCE: invention can be used in seed-fertiliser seeders. Sowing section comprises a bracket, fingers, traction rods, spring, stand, axis, disc knife, seed and fertiliser tubes, fertiliser tube, hoe. Stand is arranged as L-shaped, and axis is rigidly fixed to its lower part to hold the disc knife. Two seed and fertiliser tubes rigidly joined to each other are rigidly fixed to L-shaped stand behind disc knife. Centre hoe is rigidly fixed to lower part of seed-fertiliser tubes, and its cutting edge is arranged higher than cutting edge of disc knife, and their axes of symmetry are matched. In space underneath the hoe there are lower ends of seed-fertiliser tubes arranged, which are accordingly bent to the right and to the left. A fertiliser tube is rigidly fixed to the end of back seed-fertiliser tube, and its end is bent backwards and is arranged at the level of lower edge of disc knife. A bracket is rigidly fixed to end of upper part of fertiliser tube, and bush is arranged on it with the possibility of horizontal displacement. An axis is rigidly fixed on bush in perpendicular direction, at the ends of which there are stands fixed with limiting rollers. Rollers are arranged in vertical planes at sharp angles to direction of motion, which do not exceed 10°. A leash is hingedly fixed to bush, to which a smoothing roller is fixed, width of which is more than width of space between rows. Back part of bush and leash are hingedly joined to each other by means of length-adjustable traction rod equipped with a spring.

EFFECT: invention makes it possible to increase evenness of seeding-down and crop capacity of grain crops.
