COMBINE HARVESTER Russian patent published in 2019 - IPC A01D34/00 

FIELD: agriculture; machine building.

SUBSTANCE: combine harvester belongs to the field of agricultural engineering. Device has an energy tool with cleaning and a grain bunker, on which a block is hung, which consists of a header and an axial-rotary thresher, the axis of rotation of the working bodies of which are perpendicular to the longitudinal axis of the combine. Harvester and axial-rotary thresher are made in the form of two groups of coaxially arranged working bodies, symmetrically mounted relative to the longitudinal axis of the combine harvester. Each group has a screw with blades of the right and left winding of equal length and a finger mechanism between them, a spacer and an axial rotary thresher entrance window. Output window of the non-grain part of the harvest of both groups of working bodies is located on the longitudinal axis of the combine.

EFFECT: use of the invention ensures the achievement of the technical result, which consists in reducing the loss of grain and reducing the cost of harvesting the non-grain part of the crop.
