ROOT-TUBER COMBINE HARVESTER Russian patent published in 2016 - IPC A01D17/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine building. Combind harvester comprises frame mounted digging under tool, separating working member made in form of system of shafts, on which discs are installed in staggered order. Digging under tool in lower part is secured to frame, and in upper part moves by roller cam. On both sides of digging under tool disc blades with flanges are installed, defining depth of digging under tool. Flanges have grousers to drive roller cam via chain gearing. Separating working element has discs in form of two opposite truncated cones installed with smaller bases. External part of discs is made from elastic wear-resistant material. System of shafts with discs installed in staggered order is driven by hydraulic motor via chain gearing. Above separating working element there is drum-clod smasher made in form of pneumatic cylinder with adjustable pressure. Drum-clod smasher drive is made from support wheel of root and tuber harvesting machine through chain gearing. After separating working element inclined separator loader is mounted on frame composed of chain-converter transporter with meshed fabric. Drive of separator-loader is made from hydraulic motor mounted at upper drive shaft.

EFFECT: reduced traction resistance, higher efficiency, reduced labour intensity of harvesting.
