SOWING ELEMENT FOR AIR SEEDERS OF ACCURATE SEEDING Russian patent published in 2020 - IPC A01C7/04 

FIELD: agriculture; machine building.

SUBSTANCE: sowing element for pneumatic seed drills of precise seeding comprises seeding disk (2) for separation of seeds (S), made with possibility of rotation around axis (X), and seed duct (8) for movement of seeds (S) with initial part (12), which is located near seed extraction point (S) from sowing disk (2) and middle part (13), which passes, continuing initial part (12). Seed conduit (8) at least in initial part (12) and in middle part (13) is rectilinear and coaxial and has axis (Y), which is located inside plane perpendicular to arable land and parallel to direction of sowing continuation. Angle (B) between plane (P1), perpendicular to axis (Y) of seed duct (8) in rectilinear initial part (12) and rectilinear middle part (13) of seed conduit (8), and plane (P2) perpendicular to sowing disk (2) rotation axis (X) is less than 90°.

EFFECT: invention improves uniform seed sowing at high seeding rates.
