During the harvesting of crops, a significant amount of straw residues is formed, which can be used as raw material for subsequent processing. To assess the volume of straw suitable for processing for various needs of the agro-industrial complex, it is proposed to apply the Lotka-Volterra method. Using this method, it is possible to predict the formation of straw residues depending on the initial indicators during harvesting.

Automation of agriculture is currently a promising and actively developing branch of robotics. At the moment, there are many foreign analogues offering ready-made solutions for automatic control of sowing crops. However, in Russia, most of the sowing is carried out on mechanized plants under the mandatory supervision of a highly qualified specialist in the maintenance of the plant.

Scientific research to determine the optimal combination of technical means in the system of cleaning and sorting seeds. We carried out a system analysis of the current state of technical means of cleaning and sorting. The main task of promising research and development work is the development of a high-precision computer-based seed sorter with an electron-optical analyzer of their properties, including the internal structure of seeds. The main result of the use of a complex of technical means of electron-optical cleaning and sorting of seeds in the selection and seed production of grain crops is an increase in their yield.

The analysis of research on the separation of rice seeds on new types of polymeric sieves showed the absence of regularities that provide the studied processes. There are no dependencies describing the effect of the kinematic parameters of the operation of the sieves on the intensity of the separation processes of rice seeds. We performed a system analysis of the sieves with different types of holes. In the work, mathematical dependences between the amplitude and frequency of oscillations are determined for swinging polymer sieves.

Based on the results of theoretical and experimental studies at FGBAC FNAC VIM, we conducted a system analysis of the existing gravitational grain cleaning machines and developed a prototype of a gravity-pneumatic seed-seeding machine (VIM-3). His laboratory (preliminary) tests were carried out. The general view, constructive and techno logical scheme of the machine are presented. The prototype of a cleaning machine can purify wheat seeds up to 99.5% by feeding the processed material up to 2.5 t / h with an impurity content of more than 80%, which corresponds to the category of OS and ES of GOST R 52325-2005, as well as to international norms .

The appearance of new types of polymer gratings on the market, which have other functional and technical-operational indicators, raises the question of new kinematic solutions to their work. In this paper, questions of parametric optimization of the functioning of this type of sieves from the angle of their origin and kinematic sieves are considered. We have carried out a system analysis of existing technological schemes of lattice mills and identified promising areas of modernization.
