Electronic Pair-Action Pulsator of the Milking Machine

Abstract

The dairy cattle breeding market is analyzed. The dairy industry in the country remains one of the most problematic aspects of the economy, despite unprecedented measures of state support. (Research purpose) The research purpose is increasing the efficiency of machine milking of cows by developing and justifying the design and operating parameters of a milking machine with an electromagnetic pulsator, which allows reducing the negative impact of irritating factors during milking on animal health, ensuring fast and comfortable milking, increasing milk yield, eliminating the possibility of vacuum fluctuations in the suction chambers and working with any milking unit or apparatus. (Materials and methods) The analysis of the dairy products market and the mechanisms responsible for the formation of a pulsating vacuum during milking of lactating animals was carried out. (Results and discussion) We have developed a promising electromagnetic pulsator for machine milking of cows. It was shown that it differs from other models by the presence of a hole in the upper part of the body and a disc-shaped lower valve, which reduces air consumption and increases the reliability of the design. We solved the problem of improving the operation of milking machines and bringing machine milking closer to the physiological features of the milk-giving process. It was found that the pulsator reduces mechanical loads on the nipple tissue in lactating animals and eliminates the reverse flow of milk in the nipple chamber, which prevents the appearance of mastitis diseases. (Conclusions) Analytical studies of analogs and comparative analysis of the proposed design of the electromagnetic pulsator were carried out. It was determined that the use of a pulsator will provide a reduction in the pulse (shock) effect of the nipple rubber on the nipple tissue by increasing the transition phase from the sucking stroke to the compression stroke by 60-65 percent in comparison with series-produced pneumatic pulsators. It was revealed that with the help of the developed device, it is possible to adjust the ratio of cycles depending on the intensity of dairy production of cattle to reduce the harmful effect of milking on the health of the animal.
