SEEDING UNIT Russian patent published in 2006 - IPC A01C7/16 

FIELD: agricultural engineering.

SUBSTANCE: seeding unit has seed box, cellular drive disk with seed baffle which is closed in zone adjoining inoperative part of disk with housing, and drive for cellular disk. Disk is positioned at an angle to horizontal plane. Disk cells are shaped and sized so as to conform to said parameters of seeds and are arranged in groups on peripheral part of disk. Number of cells in group is equal to number of seeds sown into bed, and distance between groups is proportional to accepted seeding pitch (distance between beds). Annular protrusions provided between cells have width of 1.5-2.0 mm and height of 0.6-0.7 the thickness of seed. Baffle is made in the form of elastic apron attached to side wall of seed box. Baffle has elastic protrusions-seed ejectors provided in the vicinity of ejection window above shank. Seed box portion adjoining peripheral portion of disk has parabolic rounded portion of vertical wall. Conical drive of seeding disk is closed with housing.
