SEEDING ELEMENT OF SEED-FERTILISER SEEDER Russian patent published in 2010 - IPC A01C7/00 A01B49/06 

FIELD: agriculture.

SUBSTANCE: element comprises a framework with a mulch stubble sweep, cutter wheels, seed-fertiliser grain tubes and a rollers. The element is provided with an L-brace having a hinge in its centre. Support arms pivotally attached together by a length adjustable rod are rigidly fixed to the front and back pieces of the L-brace. The rod is spring loaded. The top of the front piece of the L-brace is equipped with a bushing, and a front spindle is rigidly fixed to the bottom of the brace. A central disk blade is mounted on the spindle. The off-set spindles with the disk blades mounted thereon are rigidly attached to the back piece of the L-brace on its both sides. The roller is pivotally connected to the end of the L-brace. One fertiliser tube is mounted behind the central disk blade, and the others - behind the disk blades mounted on the spindles.

EFFECT: reduced energy consumption ensured by the combination of a number of technological operations, improved crop quality due to higher field emergence by seeds laying on a hard seed bed followed by soil consolidation thereover, higher fertiliser effectiveness by simultaneous starter and bulk application, higher crop yield resulted from directed distribution of a basic fertiliser relative to the root system.
