Combine harvester improvement for selection and collection of high-quality soybeans

To obtain biologically valuable and high-quality soybeans it is necessary to improve the design of the two-phase threshing combine harvester which will have a gentle mode for threshing the most mature soybeans in the first threshing drum, make their high-quality cleaning directly in the combine harvester and collect them in a separate hopper. The first seed fraction of biologically valuable and high-quality soybeans is obtained by separating the threshed heap in the first threshing drum. It’s cleaned and collected in a separate hopper. The return is processed in the second threshing drum, and the second fraction of seeds is cleaned and collected in the second hopper of the combine. The straw that comes off the straw walker and enters the auger is divided into two parts, and when it leaves the auger on both sides, it is crushed and thrown out of the sides of the combine. At the same time, during the combine harvesting of soybeans, the chaff coming of the sieve boot and being the high-protein feed consisting of 90% of the bean flaps is collected in the chaff collector. By collecting the most valuable components of the soybean crop, i.e beans and chaff, and embedding the crushed plant stems on the small depth by disking or cultivation, the task of creating conditions for the growth and development of plants in the crop rotation with full mechanized technology of soybean harvesting is solved.
