Abstract

The purpose of the research is to determine the operability of the milking machine being developed and substantiate its optimal parameters. The milking machine contains milking cups, an original collector, a pulsator, milk and vacuum hoses, a milk receiver. The collector with the upper evacuation of milk from it. A hollow body with two curved pistons is made around the milk collecting chamber. When moving in the housing, they provide a redistributing pulling force on the teats of the cow’s udder, depending on the clock cycle of the device. A suction tube is fixed inside the collector housing, the upper end of which is located in the area of the outlet milk pipe, and the lower one is at the bottom of the milk collection chamber of the milking machine collector. An axial valve with a rod is installed on top of the suction tube, made in the form of a tube with a radial hole on the side surface. The opening during milking coincides with the outlet milk pipe and is equal to its diameter, and in the non-working position, the axial valve closes the outlet milk pipe with its side wall. The article presents the results of a factorial experiment to determine the optimal parameters of the milking machine being developed. Based on the results of a multifactorial experiment, response surfaces and lines of equal level were constructed, characterizing the amount of creeping of the milking machine on the teats of the cow’s udder, depending on the mass of the pistons in the hollow collector housing and the working vacuum pressure. As a result of the experiment and the processing of its data, the optimal design and operating parameters of the collector under development were identified. The developed design of a pair-milking milking machine with an upper milk outlet in the collector and a redistributing pulling force on the nipples of the cow’s udder, depending on the operation cycle of the device, is operable and exceeds the milking machines used in practice in its indicators.
