UNIVERSAL POTATO CULTIVATION UNIT Russian patent published in 2009 - IPC A01C9/00 A01B49/06 

FIELD: agriculture.

SUBSTANCE: unit comprises a milling part which is fitted with a milling shaft and a tube roller and is connected to the tractor by a hitch. The milling shaft is equipped by double-cantilever segments mounted as alternating sections. Some segment sections are fixed on the shaft rigidly, the other are fastened to the half-yokes which can be demounted from the shafts. Bent rippers are mounted on the segment cantilevers by bolt connections. The rippers are of a claw shape. All segments are placed on the shaft along the spiral line. The tube roller is made of flat round sidewalls and intermediate discs with the longitudinal rods being fixed on them parallel to each other. The rods are set with spiral displacement along the roller axis. Spring-loaded planting disc coulters of the planting part of the unit are placed in the same longitudinal plane as the removable sections are. The planting unit part is a combined one comprising a frame with a drawbar mechanism and carrier wheels. The frame is fitted with a tank for protective-stimulating solution with outlet nozzles of its distribution system, a fertiliser hopper, a tuber planting unit with a turnable hopper for seed potato tubers which are set sequentially. The fertiliser hopper is equipped by a bottom distribution screw and its bottom is equipped by outlet holes. A fertiliser metre made as stars is mounted in the hopper bottom holes. The metre is interacting with twin fertiliser tubes the outlet openings of which are placed inside the planting disc coulters in their back part. The outlet nozzles of the distribution system are placed in the longitudinal plane passing between the twin fertiliser tubes. The turnable hopper is equipped by separate adjacent feeders with movable bottoms. A vertical elevator-type planting conveyor is placed under each bottom. The planting conveyor is fitted by potato metering and catching cups with the distribution system nozzles being set in their discharge zone above the planting disc coulters. A potato planting depth control wheel is mounted before each coulter. Furrow covering discs are mounted behind each depth control wheel. Rotary rippers and forming ploughshares of ridging tools are set between the furrow covering discs in the same longitudinal plane as the carrier wheels of the planting part are.

EFFECT: invention allows for the improvement of the potato planting quality due to increasing the tillage efficiency along with the simultaneous planting of potatoes into the produced ridges.
