STEPLESS ONION PLANTER REDUCTION GEARBOX Russian patent published in 2021 - IPC A01C7/00 A01C19/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the field of agricultural machine building, in particular to planters for planting of materials with low flowability, for example, planting onions and seeding. Stephaned beam straightening gear of bow-sowing plant comprises body 1, overrunning clutches 2, mounted on driven shaft 3, levers of pushers 4, pivotally connected with overrunning couplings 2, springs 5, guide 6 with adjusting lever 7 and four cams 8 fixed on drive shaft 9. At that, cam working profile at approach at angle ϕ_c is made by algebraic curve - deltaoid. At that, radius r of deltaoid rounding with cam long-distance profile on angle ϕ_d is r = (0.60…0.63)R, where R is radius of pusher roller.

EFFECT: invention provides stepless adjustment of the rate of single-piece planting of onion into the furrow irrespective of the speed of the planting agent, which increases efficiency and uniformity of planting.
