FIELD: agriculture.
SUBSTANCE: invention relates to the agricultural machinery industry and can be used in harvesting agricultural crops. The pneumatic feeder comprises a ventilator driven by a hydraulic motor, a common telescopic air duct and an air pressure duct. The common telescopic air duct is connected to the ventilator by a flexible insert. The air pressure duct is mounted on the frame with the possibility of adjusting the extension and the height relative to the cutting mechanism and has nozzles and a reflector for creation of flat-directed air flow.
EFFECT: due to feeding stalks to the cutting mechanism by flat-directed air flow, knocking out of grains from spikes at harvesting is excluded.
