Hrytsun Anatoliy– PhD, Associate Professor of the Departmentof “Agro-engineering and Technical Service” of Vinnytsia National Agrarian University (3 Solnechnaya St., Vinnitsa, 21008, Ukraine, e-mail:gritsun@vsau.vin.ua).
An analysis of the technical solutions of milking machines with controlled vacuum mode and theoretical studies of the operation of the milking machine actuator, which allows to reduce the vacuum load on the udder and the impact on the sphincter of the cervix and prevent "idle" milking in high vacuum in the machine process.
The completeness of milking cows and reducing the incidence of their mastitis depends to some extent on the operation of milking equipment. Performance indicators of the technological process of serial milking equipment do not always fully comply with the current zootechnical requirements. During their work at the beginning and at the end of the milking of the animal there may be a process of "idle" milking at high vacuum, which often leads to the disease of animals with mastitis and subsequent culling. Along with the increase in milk production, quality is becoming extremely important.
The analysis of the known technical solutions of milking machines with a controlled mode of milking shows that the domestic and foreign industry do not produce milking machines with a controlled mode of milking, which fully correspond to the physiology of animals. In our opinion, the most effective one is to consider a milking machine with a low-inertial milk flow sensor, which controls the vacuum mode, both in poddyah and interstitial chambers of milking glasses.
Conducted theoretical studies of the working process of machine milking allowed to systematize the engineering calculation method of milking machine with a controlled mode of operation and to determine the optimal design parameters of the actuators. The analytical expressions obtained characterize the influence of their parameters and mode of operation on the dynamics of milk production during machine milking of cows.
