Abstract: Due to global warming, the urgency of harvesting dry short-stem grain crops will increase, and requires urgent technological and technical solutions. In this regard, research aimed at developing a device installed in an inclined chamber, which provides a reduction in grain losses during the harvesting of dry short-stem bread mass, are relevant and have an important economic value. The aim of the study was to increase the efficiency of harvesting dry short-stem grain crops. The aim of our study was to promote the expansion of technological possibilities of distribution of grain mass across the width of the inclined chamber of the combine harvester. The results showed that the threshing of grain increases due to the uniform distribution of mass depending on the length of the discrete part of the corrugation. When using the length of the discrete part of the corrugation to 0.24 m, the uniformity of distribution decreased by 19.4%. The compression ratio of dry short-stem bread mass is 4.5 ... 7. Considering the degree of distribution when changing the speed of the conveyor with discrete numbers of corrugation which were-0, 2, 4 and the angles of attack of corrugation 200, 300 we can say that the distribution is intense with an increase in speed to 2.5 m/s – 72.2%, 77.3%, 79.1% and 84.1, respectively. The results of the experiment have been obtained that the highest degree of distribution 84.1% occurs when feeding 3.5 kg / PM, with the number of discreteness 4, the angle of attack of the guide corrugations 400 and the conveyor speed 2.5 m/s. Under production conditions, losses from the converted harvester decreased from 5.5% to 1.0%; output per hour of clean work increased by 22%, and per hour of shift time - by 16%.

Key words: cleaning of dry short-stem grain, an additional device installed in an inclined chamber to improve the distribution of bread mass.
