PNEUMATIC DEVICE FOR TWO-ROW SOWING OF ROW CROPS Russian patent published in 2023 - IPC A01C7/04 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, in particular to seeders for precision seeding of row crops. Pneumatic device for two-row sowing of tilled crops includes a filling chamber, a vertically located sowing disc with through cells and a vacuum chamber. The pneumatic apparatus is supplemented with a seed flow divider, consisting of one inlet channel and two outlet channels, one of which is aligned with the plane of the sowing disc adjacent to the filling chamber. Plate guides are fixed on the sowing disc, the number of which is two times less than the number of cells, and they are placed near every second cell on a circle with a larger radius than the radius of the cell placement circle.

EFFECT: improving the quality of sowing due to two-line placement with a staggered layout of seeds, in which the shape of the feeding area becomes more convenient for plant growth.
