PLANTING UNIT FOR DOTTED-HOLE SOWING OF GERMINATED SEEDS Russian patent published in 2014 - IPC A01C7/16 

FIELD: agriculture.

SUBSTANCE: planting unit comprises a cellular drive disk mounted at an angle to the horizontal plane. The disk cells are made in the form and size of the seeds of the culture sown and placed on the peripheral part in groups, and the number of cells in a group is equal to the number of seeds sown into the hole. At that the cellular disk in the zone of cells has a wavy surface, and the cells are placed on the wave rising surface. The lower part of the cell has a seed-retaining shank. The cells are placed on the wavy surface of the disk in two rows and have jumpers. Spaces between the cells of the outer row are equal to 1.0-1.5 mm. The cells of the inner row are placed in the area of the jumpers of the outer row. Between the cells the orienting protrusions are provided with the height of 1.0-1.5 mm. On the outer surface of the disk the seed-guiding cone is attached with the generators, which angle of slope ensures sliding down of the seeds. The drive of the cellular removable drive disk is made from the support wheels of the drill through the bevel gear.

EFFECT: invention enables to provide compact holes when sowing seeds, and increase the accuracy of seeding.
