Summary: The article focuses on solving the problem of reducing the energy intensity of the process of separating ensilage fodder from trench silo with the block-portion method by developing and substantiating the parameters and operating modes of the system of hydraulic drives of the block-portion separator. This allows adjusting the operating modes of the drive of the cutting mechanism and the drive of the vertical feed of the П-shaped frame. The system allows adjusting the feed of the П-shaped frame in accordance with the change in the cutting effort that makes an effect on cutting mechanism. As a result we get stabilization of energy consumption in the process of separating a block portion of ensilage fodder if the parameters that determine the characteristics of the cutting process fluctuate. It was proved that the expansion of the range of speed adjustment of the actuating hydro-motors and, accordingly, the increase of the responsiveness of the hydraulic drive system is possible by the appropriate choice of the parameters of the slide valve. The most effective expansion of the speed range adjustment of the hydraulic motor of the cutting mechanism and the hydraulic cylinder of the drive of the П-shaped frame is provided by reducing the width of the working edges of the slide valve. The influence of the parameters of the hydraulic system of the block-portion separator of ensilage fodder on the range of speed adjustment of the operating elements has been studied. The parameters of the system of hydraulic drives which have the greatest influence on the expansion of the range of adjustment of operating modes of the hydraulic drives were established. This allows increasing the responsiveness and efficiency of the proposed system of hydraulic drives of the block-portion separator of ensilage fodder by identifying the rational values of these parameters. Recommendations on the choice of design parameters are given.
