The paper addresses the problem of improving the efficiency of machine milking by enhancing the design of the milking machine collector with due consideration of the physiological characteristics of animals. It is shown that most commercial collectors operate under fixed regimes and do not provide individual adaptation of vacuum parameters to variations in milk flow intensity, which may result in incomplete milk extraction, longer milking time, and negative effects on udder health.
The purpose of the study is to develop the design of an adaptive milking machine collector and to analytically substantiate its structural and operating parameters that ensure stable transportation of the milk–air mixture and optimal milking conditions. The object of the research is the operation process of the collector as part of a two-stroke milking machine, while the subject of the research is the relationships between its geometric parameters and operating modes.
An adaptive collector design with additional air chambers, a membrane–valve mechanism, and an adjustable throttle channel is proposed. Using analytical, computational-graphical, and physical–mathematical methods, the relationships between the throttle orifice diameter and air flow rate, the diameter of the milk hose outlet and the parameters of the milk–air mixture, as well as between the operating parameters of the milking machine and the volume of the collector milk chamber, were established.
Rational values of the design parameters were substantiated: throttle channel diameter of 1.1–2.7 mm, milk hose outlet diameter of 8–16 mm, and milk chamber volume of 121 cm³. Pulsograms of the milking machine operation with the developed collector were constructed, and the durations of the operating strokes and vacuum pressure levels were determined. The obtained results confirm the feasibility of using an adaptive milking collector to increase milking speed, stabilize the vacuum regime, and improve the operating conditions of milking installations.
