PLANTING UNIT OF POTATO PLANTER

摘要

FIELD: agriculture.SUBSTANCE: device comprises an elevator conveyor with spoons attached to it, a tuber-duct, a feeding hopper with an adjustable damper and an output window for the passage of spoons from the bottom. At the lower part of the tuber-duct a valve is mounted. And the axis of mounting the valve is installed on the inner side of the tuber-duct parallel to axes of shafts of the elevator conveyor and below the axis of the lower shaft of the elevator conveyor to the amount equal to the average total thickness of two tubers. The valve is spring-loaded relative to the axis of the valve mounting and has a shape of a hyperbolic curve of the second order. The oscillation radius relative to the axis of oscillation of the valve is 85 ? 100 mm, and the angle ? of the start of the tuber falling from the tuber-duct is 51 ? 53°.EFFECT: invention enables to increase the uniformity of distribution of the potato tubers on the bottom of the furrow.3 dwg
