POTATO DIGGER Russian patent published in 2017 - IPC A01D17/06 

FIELD: agriculture.

SUBSTANCE: digging working body is made combined, comprising vertical circular knives placed at interrows at the front of the digging working body presenting a set of plowshares made undulating in the longitudinal direction and having lugs for interaction via a connecting rod with the eccentric mechanism. The upper part of the plowshare is hinged to the frame through a height-adjustable rack. The circular knives are fixed to the frame by means of height-adjustable brackets. The upper part of the plowshare is associated with a separating working body made in the form of a piler mechanism, the pilers of which are made toothed by the Novikov gearing type. The piler mechanism is mounted on the brackets fixed to the frame. Drive sprockets connected with chain drive are mounted on the piler mechanism shafts. The piler mechanism is driven by the upper shaft by means of the hydro-motor of the tractor hydraulics system. The piler mechanism is coupled with the V-belt conveyor, the belts of which are placed at a distance preventing the passage of tobers there between. The V-belt conveyor belts are mounted on drive and idler pulleys. The driving pulleys are mounted on a shaft having a drive sprocket. The V-belt conveyor is coupled with a rod tuber-gripping conveyor, the rods of which are placed between the pulleys of the V-belt conveyor. The distance between the rods of the rod tuber-gripping conveyor is less than the diametre of the tubers to be harvested. The tuber-gripping conveyor is coupled with the loading conveyor through the pitched bars. The V-belt conveyor and the tuber-gripping conveyor are driven from the PTO shaft through the driveline and gearbox, and the loading conveyor is driven from the upper shaft of the tuber-gripping conveyor via chain drive.

EFFECT: reducing the draft resistance, complete separation of the tubers from the soil, increased harvesting productivity.
