FIELD: agricultural engineering, in particular, seeding units for single seed drills. ^ SUBSTANCE: seeding unit has seed box, conveyor provided with cells and mounted at seed box bottom, active guides and baffle. Drive run of conveyor running over drive, bypass and tension drums has portion inclined to horizontal plane, and vertical portion. Baffle is made in the form of brush-type drum and is mounted near vertical portion, rearward of bypass drum. Baffle is provided with movable cutoff device, which is secured at an angle to horizontal plane, on seed box rear wall. Active guides formed as flexible rods are fixed on seed box front wall, in parallel with inclined portion of conveyor drive run. Brush-type drum of baffle and drive drum of conveyor are kinematically connected through synchronizing transmission. Drive drum of conveyor is disposed above seed guide. Surfaces of drive, bypass and tension drums are reinforced with friction material. ^ EFFECT: increased efficiency owing to uniform single-seed discharge of seeds from seed box and feeding thereof into seed guide. ^ 5 cl, 1 dwg |
