FIELD: agricultural engineering; grain harvesters.
SUBSTANCE: invention can be used in grain harvester threshers. Proposed sieve is provided with chutes open from top arranged parallel to its longitudinal axis and limited by base and adjoining side surfaces with apertures. Two air feed channels separated from each other by continuous partition are placed between two chutes following each other in cross direction to longitudinal axis of sieve. Apertures in side surface of chutes are open only to one of two air feed channels divided by partition. Air feed channels are open from lower side of sieve.
EFFECT: improved passing of air flow in air feed channels, prevention of clogging of sieve by parts of stalks.
