| Popis: | The article considers the following issue: that further improvement of the grain combine design with the classical threshing-separating device is possible due to the development of its technological scheme based on the principle of modular construction and stationary process of threshing grain mass. To achieve this goal, the problems were solved, by which laws were revealed and a mathematical description of the technological process of the combine harvester was given, as well as patterns characterizing the effect of straw on the process of threshing the grain mass were revealed. It is revealed that the coefficient of straw of grain mass is possible to reduce during combining, grain crops through the application of high-cut stems. Production check has established that the technological resource of this process of direct grain crops harvesting is limited due to the increase of the negative impact of both the ratio of grain and straw by weight and the height of the cut of the stems on the agrotechnical indicators (grain loss) of the combine. |
