Introduction. Improvement of the agro-industrial complex involves the creation of new and modernizations of existing working tools and machines. The important conditions for this are the application of modern technologies and ongoing cooperation with the actual manufacturing. The aim of the research is to develop an adaptive centrifugal working tool and improve the quality of mineral fertilization. Materials and Methods. The adaptive centrifugal working tool was developed and manufactured based on studying the state of the matter and requirements to machines for mineral fertilization. At all stages of the research, there were used computer-aided design and rapid prototyping methods based on additive technologies. Results. As a result of the use of the presented working tools, the machine operating width has increased by 10.0‒22.5%. Experimental working tools, in comparison with serial ones, allow decreasing uneven distribution of mineral fertilizers by 13.4% due to their redistribution from the central zone to the edges. Discussion and Conclusion. As a result of experimental studies, the efficiency of the developed adaptive centrifugal working tools has been proved. It allows increasing uniformity of mineral fertilizer distribution and the machine operating width. Modern design methods make it possible to considerably reduce time and costs.

Introduction. Modern agricultural production is based on the use of resource-saving technologies for agricultural production. An important element of these technologies is the use of mineral fertilizers and special importance is given to the uniformity of applying them. Aim of the Study. The study is aimed at improving the process of applying mineral and lime fertilizers through the development of a pneumatic centrifugal working body. Materials and Methods. For the theoretical studies, there were used the principles of mathematics and theoretical mechanics. The experimental studies were carried out at the testing ground of the Institute of Mechanics and Energy of Mordovia State University. The quality assessment of the operation of the unit equipped with experimental working bodies was carried out in accordance with GOST 28714-2007. Results. To better distribute mineral fertilizers of heterogeneous granulometric composition over the field surface, there has been proposed a working element, the operating principle of which is based on the total use of mechanical and pneumatic effects on the granules of the agricultural inputs. The use of the developed working bodies makes it possible to increase the uniformity of fertilizer application by 17.6%. Discussion and Conclusion. As a result of the conducted study, there has been proven the effectiveness of using the developed pneumocentrifugal working body, which makes it possible to increase the uniformity of distribution of mineral and lime fertilizers.

Most of the cultivated fields in Russia are acknowledged to have irregular contours, therefore mineral fertilizers are applied irrationally at the field boundaries. To eliminate this problem, the manufacturers of solid mineral fertilizer spreaders offer several technological solutions: in most cases, the application area is limited by changing the granule flight path. (Research purpose) To develop a distributor disc for a variable application area to use in mineral fertilizer spreaders equipped with variable rate application systems. (Materials and methods) The trajectory for applying mineral fertilizer granules was estimated depending on the bend angle of the distributor disk blade. We designed 3D disk models with a variable blade bend angle from 0 to 25 degrees, which were uploaded into the RealFlow program for the subsequent simulation of solid mineral fertilizer distribution. (Results and discussion) The coordinates were obtained for mineral fertilizer granules that dropped from the disk and landed on the surface. We built graphs of the mineral fertilizer distribution on the field surface. It was found out that changing the bend angle of the distributor disc blade within a 20-degree range makes it possible to vary the granule flight path within 10 meters of width and 8 meters of length, respectively. We developed a design of a mineral fertilizer distributor disk with an adjustable application rate. (Conclusions) A disk design was proposed for a smooth change in the blade bend angle within up to 25 degrees, which will allow the use of this system in conjunction with automated rate application systems, improve the distribution accuracy of solid mineral fertilizers and ameliorants in the boundary, edge and wedge-shaped sections of fields.
