PLANTING UNIT Russian patent published in 2012 - IPC A01C7/16 

FIELD: agriculture.

SUBSTANCE: planting unit contains a seeding disc 1, a hopper 7 with a seeding slit 9 and a shield 8 attached to the inner wall of the hopper 7. On the seeding disc 1 the fixed rods 2 are mounted in rows. Opposite the seeding slit 9 a horizontal seed- discharging shaft 3 is mounted radially with elastic needles 4. The needles 4 have a rectangular cross-section and are arranged in a helix line so that the main central axis of inertia of the rectangular section of the needle with the smallest moment of inertia coincides with the line of the helix line scan. At that the length of the elastic needles 4 exceeds the distance from the lower edge of the seed- discharging shaft 3 to the surface of the seeding disc 1.

EFFECT: use of the invention enables to provide a uniform dosage of hard-running seeding material with high humidity.
