摘要

This paper presents the indicators of quality of the grain obtained by harvesting winter wheat with conventional and rotary combine harvesters. It was identified that rotary combines substantially decrease both shattering and micro-damage to grain. The results of the research indicate that agribusiness enterprises should primarily use rotary combines to harvest seed crops. This, in turn, will allow to raise the qualitative characteristics of the seed grain, reduce the seeding rate and increase the crop yield. During the post-harvesting handling of grain heaps that arrive at the grain cleaning assemblies working according to the fractional flow technology using the universal high-performance machine, it is necessary to separate the forage fraction of grain with seeds less than 2.6 mm. This will allow to remove the air-screen cleaner machine for the secondary cleaning as well as the indented cylinder unit while removing the need for two norias for transporting grain towards them and moving it with the auger in the indented cylinder unit. Coarse impurities and unthreshed grain will be separated by a seed blower. This way, broad use of rotary combine harvesters to harvest cereal crops will allow not only to reduce shattering and micro-damage to seed grain during harvesting but also to simplify the seed-cleaning plant, which in turn will lead to reduced costs of postharvest handling of market grain and seeds.
