SHANK FOR SOWING OF SMALL-SEEDED FARM CROPS Russian patent published in 2005 - IPC

FIELD: agricultural engineering.

SUBSTANCE: shank has tine with cheeks, cylindrical furrow-cutting drum mounted on frame, seed guides, and covering roller. Rectangular elastic blades are arranged in radial rows on surface of cylindrical furrow-cutting drum, at an angle to axis of rotation of drum. Sweeps are disposed on frame of cylindrical furrow-cutting drum, at sites where blades are inserted into seed guides. Seed guides are defined by outer surface of cylindrical furrow-cutting drum and U-shaped housings tightly adhering to elastic blades of each row on cylindrical furrow-cutting drum. Seed distributing devices mounted in lower part of seed guides are defined by horizontal surfaces formed by round metal rods. Rods are extending in parallel with one another within each horizontal surface and rods of two adjoining surfaces are arranged in mutually perpendicular orientation. Rods of even and odd surfaces are staggered with respect to one another.

EFFECT: increased uniformity in distributing of seeds at drilling depth and over feeding area.
