PLANTING MACHINE AND METHOD OF PLANTING BULB ONION MOTHER PLANTATIONS Russian patent published in 2015 - IPC A01C11/00 A01C5/04 

FIELD: agriculture.

SUBSTANCE: method of planting bulb onion mother plantations comprises forming holes, planting bulb onion mother plantations to the holes with the collum downwards and long-term preservation them of the indicated position. To form compacted walls and bottom of the holes each basin harrow is quickly impressed in the soil and instantly removed from the soil by the drive mechanism of the machine for planting bulb onion mother plantations. The machine comprises a beam bearing a gear, a bracket with leads, a hopper for planting material, covering units, supporting-sealing wheels, a seat for the planter, basin harrows, drive mechanisms of basin harrows. The drive mechanism of each basin harrow is made in the form of the two-arm lever mounted on the inner surface of the rim of the support-drive wheel and oscillating in a plane perpendicular to the plane of the support-drive wheel, the stationary bracket for basin harrow impressing into the soil, and the compressed spring which rests on one arm of the two-arm lever, on the other arm of which the basin harrow is secured. Fast impressing of the basin harrow in the soil and instant removing it from the soil not only retains the desired shape of the hole, but compacts the side walls and the bottom of the hole, which keeps the position of the planted bulb onion mother plantation with the collum downwards from the moment of planting and for the entire growing season.

EFFECT: invention enables to improve germination of onion mother plantations.
