Under the current conditions of price growth, the expansion of agricultural enterprises and the creation of new ones based on them, the economic feasibility and practical possibility of purchasing the necessary equipment has significantly decreased. In connection with this and with the aim of expanding the functional capabilities of the technical means available in farms, the application of devices to serial machines is becoming more and more effective. The article presents an overview of modern attached screw equipment for quick unloading of motor vehicles. When designing screw equipment, it is necessary to take into account the peculiarities of their transport properties. The transportation of bulk goods by angle screw equipment depends on the frequency of rotation and the level of filling of the conveyor with the product. Structural and mechanical properties primarily depend on the density of packing of particles of loose material, their relative mobility. The mechanical properties of such a structure can be described by the equivalent modulus of elasticity and the equivalent Poisson's ratio. The nature of energy transfer in a loose material is largely determined by the forces of friction and adhesion at the points of contact of its particles. A characteristic feature of screw conveyors is that the screw working body is freely (without supports) located in an elastic or rigid casing and along its inner surface transports the material to the unloading area. The article presents the main theoretical ratios for determining the effectiveness of hinged screw products. A study was conducted to determine the influence of the main technical parameters on the performance of high-speed conveyors at a large angle.

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.
