FIELD: agriculture.
SUBSTANCE: air seeder comprises a tank for the product, having a space inside, a plurality of row sections, a pneumatic distribution system, a plurality of discharging devices, a terminal device of global positioning system (GPS) and an electric circuit for data processing. The pneumatic distribution system comprises an air source and a plurality of distribution pipelines. At that the said air source is in communication with the space inside the tank for the product. Each distribution pipeline is fluidly connected to at least one respective row section. Each of the discharging devices comprises a splitter with inlet and outlet openings. The inlet opening is connected to the air source. And the first outlet opening is connected to at least one distribution pipeline. The second outlet opening is in communication with the space inside the tank for the product. The terminal device of GPS provides output signals corresponding to the location of at least one row section. The electric circuit for data processing receives the output signals from the GPS, and selectively controls operation of the plurality of splitters according to the output signals of GPS for selective discharging air and involved product from the inlet opening to one of the said first outlet opening and second outlet opening.
EFFECT: invention enables to implement the automatic control of seeding in each row.
