Abstract
Purpose. Improving the reliability of the results of the study of the working bodies of the individual compound feed dispenser by improving the method of their implementation. Methods. Experimental research of the working bodies in individual metering of feed were carried out using the laws of kinematics and dynamics and with the use of strain gauges. Method planned experiment using the theory of screening experiment, statistical processing of research results with the use PC. Results. The experimental installation has been developed for research of cone and cone-blade working bodies by individual batcher of compound feeds with devices for measuring, registration and transfer of information by electric signals of the current values mass stream in dynamic mode, display and storage of information and control and measuring devices for measurement power of process dosing and irregularity delivery of compound feed. Weight of compound feed in the bunker by individual batcher, changes direction movement stream of compound feed. The technique of experimental researches using the theory of screening experiment by random balance, the factors are equal to their variation, which affect the optimization criterion of the individual feed dispenser, the matrix plan of the screening experiment, the equation for determining the effects factors and the physical and mechanical properties of feed. Conclusions. Research of the working bodies in the individual feed dispenser according to the proposed technique of the random experiment by the random balance method makes it possible to establish significant and insignificant research factors (diameter and speed of the cone working body, height and number of blades, the angle of the cone at its base, the ring gap between the outlet neck of the hopper and the cone working body), to increase the reliability of the results of the experiment. Keywords: individual dispenser, experimental installation, operating part, productivity, optimization criterion, mixed fodder.
