The use of robotic platforms in agricultural production is becoming an increasingly popular area of scientific research. A particularly relevant area is the use of robotic platforms for the application of pesticides and mineral fertilizers, since human work with these preparations is associated with health risks and is limited in duration. Replacing human labor with robot work is an important direction and makes it possible to increase the economic efficiency of fertilizers and pesticides by adjusting the components of shift time. In addition to the economic component, an important issue is to increase the uniformity of the distribution of fertilizers over the surface, as well as the application of specified doses in accordance with the nutrient cartogram in the soil, while differentiated application should be carried out not only in the direction of movement of the robotic platform, but also in the working width, which can be achieved by using a screw distributor with controlled fertilizer dispenser. The application of these principles on robotic platforms will reduce the unjustified consumption of solid mineral fertilizers and reduce the environmental impact, increasing the environmental efficiency of fertilizer application. To improve the quality of fertilizer distribution by the robotic platform, it is necessary to carry out experimental and theoretical research to substantiate the main design and technological parameters of the distribution element of the robotic platform, taking into account their interaction with the flow of fertilizer particles. Software applications for modeling the discrete element method (DEM) are the most important tools for these purposes. The most important initial data affecting the accuracy of calculations is information on the properties of solid mineral fertilizers, such as coefficients of internal and external friction, granulometric composition, dimensional characteristics, density and bulk mass. In this regard, the purpose of this work was to study the missing physical and mechanical properties for DEM modeling.

摘要

The use of robotic platforms in agricultural production is becoming an increasingly popular area of scientific research. A particularly relevant area is the use of robotic platforms for the application of pesticides and mineral fertilizers, since human work with these preparations is associated with health risks and is limited in duration. Replacing human labor with robot work is an important direction and makes it possible to increase the economic efficiency of fertilizers and pesticides by adjusting the components of shift time. In addition to the economic component, an important issue is to increase the uniformity of the distribution of fertilizers over the surface, as well as the application of specified doses in accordance with the nutrient cartogram in the soil, while differentiated application should be carried out not only in the direction of movement of the robotic platform, but also in the working width, which can be achieved by using a screw distributor with controlled fertilizer dispenser. The application of these principles on robotic platforms will reduce the unjustified consumption of solid mineral fertilizers and reduce the environmental impact, increasing the environmental efficiency of fertilizer application. To improve the quality of fertilizer distribution by the robotic platform, it is necessary to carry out experimental and theoretical research to substantiate the main design and technological parameters of the distribution element of the robotic platform, taking into account their interaction with the flow of fertilizer particles. Software applications for modeling the discrete element method (DEM) are the most important tools for these purposes. The most important initial data affecting the accuracy of calculations is information on the properties of solid mineral fertilizers, such as coefficients of internal and external friction, granulometric composition, dimensional characteristics, density and bulk mass. In this regard, the purpose of this work was to study the missing physical and mechanical properties for DEM modeling.
