Abstract

The issue of increasing the efficiency and reducing the energy consumption of the technological operation of unloading stem fodder (silage and haylage) from trench storage by block-batch method, due to the development and justification of parameters and modes of operation of the adaptive hydraulic drive system. Recommendations for determining the range of speed control of the working bodies of the mechanism for separation of stem forages on the basis of the developed system of hydraulic actuators of the separator mechanism with maintenance of energy saving mode of the pumping station and investigated nonlinear mathematical models mechanism and features of functioning of executive hydraulic motors of drives of the cutting mechanism in the mode of adaptation to real character of process of separation of a stalk forage. According to the results of mathematical modeling rational values of parameters of the developed hydraulic system of the mechanism for separation of a stalk forage corresponding to area of steady work of system are established, influence of components of hydraulic units of system of hydraulic drives of the separator mechanism regulation of speeds of the working bodies which are put in action by executive hydraulic motors. Based on theoretical and experimental studies, it was found that reducing the width of the working edges of the spool leads to the most effective expansion of the technological range of speed control of the separation mechanism driven by the hydraulic motor - cutting mechanism and hydraulic cylinder - drive P - shaped frame. As a result of research of influence of parameters of the developed hydraulic system of the mechanism for separation of stem forages on the range of technical regulation of speed of working bodies, constructive and technological parameters of the developed hydraulic drive are revealed. Determining the most optimal values of these parameters will increase the sensitivity and efficiency of the proposed hydraulic drive mechanism for the separation of stem forage. According to the results of the research, recommendations for the choice of structural and technological parameters of the developed hydraulic system of the mechanism for the separation of stem forages are provided.
