In the vast majority of modern combine harvesters, scraper elevators with centrifugal unloading are used for grain transportation. The main disadvantages of such elevators include: direct and reverse grain pouring; crushing and compression damage to the grain by the working bodies of the scraper elevator; lack of consideration of the physical and biological characteristics of the grain of various crops harvested by combines. Such elevators have one nominal speed of movement of the chain with scrapers, do not consider the degree of loading of the grain-transport line of the threshing machine. For example, when threshing grass seeds with a KZS-9-1 "Slavutych" combine, the productivity of the scraper elevator is on average 0.1...0.3 kg/s, and it is designed for 5...5.5 kg/s., we have increased energy costs for transportation.
Another problem is aimed at reducing the degree of crushing and compression damage to the grain by the working bodies of the scraper elevator of the combine harvester. And the disadvantage of the mechanical drive of the elevator is also the constant ingress of part of the grain into the gap between the hinges of the chain with scrapers and the drive sprocket.
According to the results of experimental studies, it is possible to determine that on modern combine harvesters it is advisable to introduce an electric drive with computer control of the speed of grain transportation both by the scraper elevator and by the grain transport group as a whole. For the KZS-9-1"Slavutych" combine harvester, the speed of grain transportation can be changed in the range of 260…360 min-1 with an increase in the centrifugal unloading sector to 1600. At the same time, the use of an electric drive also solves the technical problem of replacing the axial side feed of grain from the lower grain auger of the combine thresher with a radial top feed. This solution will reduce grain destruction.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
