Research in milking machine of pairwise combined type

It is known that improving the process and means of milking can increase the productivity of cows by 25–30%. Perfection of the design, interaction of the parameters and mode of operation of the milking machine have a special impact on the health, productivity of cows and milk quality. Parameters and modes of operation must correspond to the physiological characteristics of the process of milk production. Modern milking machines with a pair of milking cups ensure a stable flow of milk from pairs of teats into the collector chamber, doubling the irritation, which also has a synchronous uniform irritation of teats and udder halves. Milking machines with single action have high stability of milk supply to the collector chamber. Such devices also have much lower intensity of milk production. Improving the milking machine by changing the parameters in the milk cup by changing the operation of the control element (pulsator) will ensure asynchronous operation of the milking cups and increase the number of stimulating teats and udders during milking. A milking machine with paired-combined action is proposed, in which phases alternate during a certain cycle: simultaneous sucking phase in both pairs of milking cups, sucking phase in one when compressed in another pair of cups (milk is excreted in these phases) and simultaneous compression phase in both pairs (in this phase there is udder massage). The rational difference in pulsation frequency in pairs of milking cups is in the range from 0.1 to 0.2 Hz. The proposed mode of the milking machine increases the amount of milk produced during machine milking by 13.9% and its total yield by 8.2%, as well as reduces the duration of machine milking by 1.9… 2.1 times.
