GRAIN HARVESTING UNIT Russian patent published in 2018 - IPC A01D41/04 

FIELD: agriculture; mechanical engineering.

SUBSTANCE: invention relates to mechanization of agricultural production, namely to machines for harvesting grain crops. Grain harvesting unit comprises a header, a combine harvester, with two threshing machines, a straw separator, a main and additional agitator board, small pile separator, transporting devices, a hopper and straw chopper-spreader, as well as a trailer container. Additional agitator board of the combine harvester is placed under the first threshing machine and is adjacent to an additional grain screw conveyor connected with an additional discharge screw conveyor. Trailer container is equipped with a system of unloading screw conveyors. In the upper part of the container there is a small pile separator, with a finish grinding system and distribution screw conveyors.

EFFECT: use of the claimed invention makes it possible to optimize the layout of the grain harvesting unit, which allows to improve the quality of separate collection of grain of different biological value.
