Lower edge of charging window is extending along generatrice of drum, at the level of its horizontal diametrical plane. Seeding window edge closest to charging window is extending along lower generatrice of drum. Radial fingers are provided on internal surface of drum, between lower edge of charging window and seeding window. Radial fingers are arranged in rows along drum generatrices. Rows of fingers are arranged in spaced apart relation with respect to one another, with gaps between fingers of one row of fingers being overlapped with fingers of adjacent row of fingers. Row of fingers disposed in front of seeding window is spaced from the latter by interval.

EFFECT: increased efficiency owing to improved seeding uniformity.
