ROLLER CONVEYING DEVICE FOR ORIENTATED PLANTING OF BEET MOTHER PLANTS Russian patent published in 2017 - IPC A01C11/00 

FIELD: agriculture.

SUBSTANCE: device for oriented planting of beet mother plants comprises the receiver, the rolls consisting of two parts - the cylindrical one, having a helical winding of elastic nap, and the smooth conical one, under which there are trap trays fixed on the crankshafts of the planting apparatus. The helical winding has a variable pitch (p_i), and the elevation angle of the helical line (ϕ_i) on the cylindrical part of the rollers is determined by the dependence of the arithmetic progressionϕ_i=ϕ₁(i-1)⋅d, where i is an ordinal term of the arithmetic progression; d -the progression difference pitch; ϕ₁ - the first member of the arithmetic progression (the initial elevation angle of the helical line), deg; , where K_v - a coefficient depending on the physical and mechanical properties of a transported load, for lumpy ones K_v=0.8…0.9.

EFFECT: invention will increase the reliability of single-piece feeding of conical-shaped root crops regardless of their geometric parameters for their oriented planting.
