MONODISC COULTER Russian patent published in 2021 - IPC A01C7/20 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, in particular, for direct sowing of agricultural crops. A single-disc coulter contains a flat disc, a shoe with a blade, a seed pipe, a fertilizer hose, a depth control wheel with a rubber rim, a cleaner, a seed clamping wheel, a rolling wheel mounted on a parallelogram suspension. The cleaner with a replaceable tip and the depth control wheel are mounted on their own parallelogram suspension with the possibility of maintaining their relative position relative to the disk when changing the depth of seed embedding. The disc, mounted with a horizontal tilt back by 7-8°, is equipped with an annular cleaner supported by a spring on the inside of the depth control wheel housing, and a rotary drive mechanism with an overrunning clutch from the depth control wheel.

EFFECT: invention provides optimal conditions for plant germination by laying seeds in clean, moist soil without crop residues and evenly deepening the coulter into the soil.
