OPENER FOR EMBEDDING SEEDS AND FERTILISERS INTO SOIL Russian patent published in 2014 - IPC A01C7/20 

FIELD: agriculture.

SUBSTANCE: invention relates to the agricultural machinery industry, in particular to the combined openers producing row sowing the seeds of agricultural crops. The opener comprises a rack with a pointed flat hoe at the lower part. In the alignment of the rack a circular blade is located. The circular blade has flanges and is mounted to the rack with the L-shaped brackets having outlets in the area of flanges. The rack is connected to the circular blade along the radius equal to the radius of the circular blade. At the lower part of the rack a wedge removable furrow-forming device for seeds, mounted using screws with countersunk head. Near the rear side of the rack the seed-duct is mounted, coupled with the lower edge of the A-hoe. Behind the seed-duct the lower part of the wings of the A-hoe is fixed with screws with the countersunk head to the wedge furrow-forming devices-coverers for fertiliser, placed near both hoe wings with the ability to compress the walls of the furrow for the seeds. Behind the furrow-forming devices-coverers a fertiliser hose with a divider-flaring is attached to the rack. The upper edge of the A-hoe to the fertiliser hose is covered with a shield behind which on the upper part of the hoe wings the soil-guides are fixed. The soil-guides are mounted at an angle to the direction of the opener motion.

EFFECT: constructive implementation enables to improve seed germination and agricultural crop yield due to the greater availability of fertilisers.
