METHOD OF HARVESTING GRAIN CROPS AND A CEREAL HARVESTING MACHINE FOR ITS IMPLEMENTATION Russian patent published in 2021 - IPC A01D34/00 A01D41/06 A01D41/12 A01D57/00 A01D75/02 

FIELD: agriculture.

SUBSTANCE: inventions relate to agriculture. Harvesting method of cereal crops harvesting includes harvesting of the crop mass from the field, its threshing, grain cleaning, pneumatic selection from the earth's surface of grain losses behind the combine cutting head, their supply for threshing, wherein in addition from the selected crop losses, a fraction of grain and spikes suitable for further use is separated, which is directed into the threshing separating device, and fraction of selected crop losses is not suitable for further use and is directed together with selected seeds of weeds for recycling. Combination machine includes a harvester, a threshing device, an air-screen cleaning system, a pneumatic baler, and it is additionally equipped with a separating device, a material pipeline and a slope for extraction and transportation to the threshing separating device of seeds and spikes selected from the field, which are suitable for further use, and separation and recycling of seeds of weeds and crop losses, which are unsuitable for further use.

EFFECT: inventions allow improving the quality of grain crops harvesting and reducing the treated fields contamination.
