METHOD OF HARVESTING GRAIN CROPS AND COMBINE HARVESTER FOR IMPLEMENTATION THEREOF Russian patent published in 2020 - IPC A01D41/12 A01D91/04 

FIELD: agriculture.

SUBSTANCE: group of inventions relates to agriculture. Method consists in mowing, threshing and heap separation in a grain-harvester to separate flows of grain, straw and chaff, spread of straw and chaff over the field. Light impurities, dust and seeds of weeds are separated in an inclined chamber in front of the main threshing device by tightening said fractions with air flow into perforated rotating cylinders for subsequent recycling. Combination machine comprises a harvester, an inclined chamber, a threshing separator. Inclined chamber is additionally equipped with a row of transporting perforated cylinders with a shell, having a flow section less than the size of threshed grain. Inner cavity of cylinders is connected to pipelines for direction of isolated light impurities, dust and seeds of weeds for recycling.

EFFECT: reduced power consumption of the process and improved quality of threshing and separation of grain heaps, reduced contamination of harvested fields, preservation of favourable environmental conditions and safe operation.
