Abstract

The article deals with the problem of increasing the efficiency of mechanization of forage harvesting in animal husbandry. According to the analysis of mixer designs and installations, a pilot project was proposed to cover the entire range of devices presented. A method for evaluating the quality of a mixture (degree of uniformity) with continuous introduction of components is proposed and a diagram of a laboratory installation is presented. Experimental studies have shown the feed range of the installation at different speeds of rotation of the impeller shaft. Mixing studies have confirmed the effectiveness of the plant design and its components: feeder, pump and mixer. Using experimental planning methods, the main factors influencing the mixing process were identified and the optimal parameters of the mixture quality were determined. When the unit was operating as a pump, a range of feeds in an open and closed loading chamber was obtained, and mixing quality indicators with continuous introduction of components, as well as water temperature t = 25...38 °C and the rotation speed is n= 1500...1600 min-1 reached the value of uniformity degree Θ=94.8%.
