FIELD: agriculture; machine building.
SUBSTANCE: invention relates to agricultural machine building, in particular, to seeders for different-bottom nesting of row crops seeds. Seeder section comprises frame, articulated-lever suspension, seed box, pneumatic sowing device, sowing disk, ploughshare with left, right and main compartments, harvester, roller and train. Under the pneumatic seeding device there is a distributing device in the form of a roller with three cells, which axes are located at angle of 45° relative to each other. Roller is fixed on the drive shaft, which provides synchronous rotation of the sowing disk due to chain transmission. Profile of the first and the third cells has a curvilinear surface that connects the middle part of the roller with the right and left parts of the roller, respectively. Second cell is located in the middle part of the roller and its profile is cone-shaped. Left and right parts of roller are separated from its middle part by means of two fixed discs, each of which has cutout, sizes of which correspond to dimensions of first and third cells.
EFFECT: invention allows to increase accuracy of seed distribution in compartments of the shovel.
