SUBSURFACE BROADCAST SOWING SHARE Russian patent published in 2002 - IPC

FIELD: agricultural engineering. SUBSTANCE: share has A-hoe attached to tine-seed guide, and conical distributor. Arch-forming corner plates are rigidly attached to left-hand and right-hand sides of tine-seed guide. Conical distributor is attached through pivot pin to bracket in cavity under hoe. Diameter of conical distributor base end is 1/3 the width of A-hoe and height thereof is 3/5 the height of cavity under hoe. Such construction allows width of soil strip adapted for sowing to be increased, uniformity of seed and fertilizer distribution to be improved and discharge channel to be prevented from clogging. Share may be used for subsurface broadcast sowing of cereals combined with discharge of mineral fertilizer as well as without it. EFFECT: wider operational capabilities, simplified construction and enhanced reliability in operation. 2 dwg
