COMBINE FOR HARVESTING TUBEROUS ROOTS Russian patent published in 2016 - IPC A01D17/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine building. Combind harvester comprises trimming ploughshare, separating bar conveyors, clod removing drum. In front part of machine disk knives are arranged on frame in space between rows of plantations of tuberous roots. Diameters of knives have been taken from condition of cutting formation in vertical plane at depth of location of tuberous roots. Cutting blade is connected to lower bar conveyor having speed V1 and hinged on frame of combined harvester. Drive drum of lower bar conveyor is fitted inside drum conveyor cavity. Above lower bar conveyor there is upper bar conveyor with function of clod removing drum. Bars speed V2 is smaller than speed of bars V1. Lower part of upper bar conveyor is fixed by expansion spring. Top drive drum of top bar conveyor is mounted on posts secured to frame, and is driven to drive drum of lower bar conveyor. Drum-type conveyor is cantilever installed with help of hub on post secured to machine frame. Rear wall of drum conveyor is made of mesh and in inner cavity along periphery of drum there are blades. Outer drum carcass is made by bars and is connected with hub by spokes with distance between spokes enabling passage of soil and to prevent passage of tuberous roots. Drive of drum conveyor is made from hydraulic motor, and drive of rod conveyors is made from tractor power take-off shaft via reduction gear. In upper part of drum conveyor there is shipping conveyor with drive from hydraulic motor.

EFFECT: complete separation of tuberous roots from soil, higher efficiency at harvesting.
