COMBINED COULTERS Russian patent published in 2016 - IPC A01C7/20 

FIELD: agriculture; engineering.

SUBSTANCE: opener includes a frame, and seed-sowing fertilizer distributing machines, rack with lancet subsurface cultivator paw at the bottom, and the vas deferens fertilizer hose mounted behind the bar. Fertilizer hose of fertilizer distributing machine with auger filler is connected to the pressure chamber of the fan. Seminal duct sowing apparatus is directed into the groove formed by the wedge heel. Heel formed in the lower part of the lancet paws. At the bottom of the paw lancet fixed fertilizer distributor flow divider fertilizer-air mixture. Feritilizer distributor at the outer upper edge of the lancet paws has output window.
