Baffle formed as brush-type drum is mounted above horizontal portion behind bypass drum and is equipped with movable cutoff device secured at an angle to seed box rear wall. Active guides formed as flexible rods are disposed on front wall of seed box, in parallel with inclined portion of conveyor leading run. Guides for flexible members of pull-type drum are extending in parallel with inclined portion of conveyor leading run. Brush-type drum of baffle and drive drum of conveyor are kinematically connected through synchronizing transmission. Conveyor drive drum is mounted above seed guide. Front wall of seed box is equipped with seed cutoff device for cutting off seeds from conveyor cells. Surfaces of drive drum, bypass drum and pull drum are reinforced with friction material.
