POTATO HARVESTER Russian patent published in 2017 - IPC A01D17/00 A01D27/04 

FIELD: agriculture.

SUBSTANCE: invention relates to the agricultural engineering industry. Harvester comprises a knife for trimming the tops located in front mounted at an acute angle to a horizontal conveyor plane, and a device for digging the roots, placed below the knife, which is configured as a plowshare, mounted at an acute angle to the horizontal plane between the vertical disc blades has a top side on the soil horizon level, soil destructing drums are mounted on the window pillar coulters via sliding bearings to the underside of the coulter. On the outer surface of the teeth, soil destructing drums are provided. They are made with a circular shape side profile - Novikov gearing. The distance between the soil destructing drums is made under the conditions to prevent getting the tuber between the drums. The upper edge of the coulter is associated with an inclined roller conveyor, which is driven by rollers rotation of the support track. Inclined roller conveyor is associated with Horizontal Bars conveyor, which is equipped with cam shaker. The output unit horizontal transporter bar stock is placed in the inner cavity of the conveyor drum comprising an outer cylindrical shell, which is fixed on the outer perimeter of the grating rods coated with elastic material. Fruit grabbing blades are radially mounted in the inner part of the conveyor drum. Drum conveyor is cantilevered mounted on the rack, which is placed on the frame of the harvester. Sloped tray of the loading tubers craft is mounted In the upper part of the conveyor drum. Drive of all the working parts made from the PTO shaft through a reduction gear and chain drives, and conveyor drum motor drive is made by the tractor hydraulics.

EFFECT: invention provides a complete separation of the tubers from the soil, improves performance and comprehensive mechanization of harvesting.
