THEORETICAL SUBSTANTIATION OF THE WORKING BODY PARAMETERS OF THE MINERAL FERTILIZER DISTRIBUTOR

Abstract

The study is devoted to solving the problem of reduction ofnonuniformityof application of mineral fertilizers. It was established that many factors influence distribution of fertilizers. The design of the working body of the mineral fertilizer distributor was developed and patented,it allows to increase the uniformity of fertilizer distribution. Differential and stochastic differential equations that describe the movement of fertilizer particles along the diskare given. The stochastic equation takes into account random impact interactions that inevitably arise during the motion of the particle flow. Dependences were obtained that determine the relation between such kinematic parameters of a fertilizer particle as the speed at the exit from the disk and the angle between the speed and the disk plane with geometric parameters of the distributor working body. The coordinates of the place where a fertilizer particle falls on the ground are determined, which allow to establish the dependence of the spreading width and distance on geometric and kinematic parameters of the working body, as well as physical and mechanical properties of fertilizers. In the course of the theoretical study, it was found that it is possible to regulate the torch of fertilizer spreading on the soil surfaceby changing the parameters of the working body of the mineral fertilizer distributor, which allows to achieveappropriate conditions that ensure the required uniform distribution of fertilizers.
