THE INFLUENCE OF THE PARAMETERS OF MILK CHAMBER OF THE COLLECTOR ON OPERATING MODES OF THE MILKING MACHINE

Structural solutions of the serial collectors of milking machines do not fully take into account the peculiarities of milk transportation to the upper milk pipe of milking machine. The assessment shows that the issue of matching the intensity of milk yield with the functioning modes of the milking machine remains unclear. Scientists note that the milk transportation mode affects the quality of milk. Thus, uncontrolled variables over time of milk velocity in a flexible line of milk cause dispersion of fat globules and foaming of milk, which worsens its technological properties. The influence of the structural and technological parameters of the milk chamber and the milk tubulure of the milking machine's collector on improving the efficiency of the technological process of machine milking of cows is established. The fullness of the milk chamber of the collector influences the intensity of the milk output to the lineof milk of the milking unit. A certain level of milk in the milk chamber of the collector provides a sufficient pressure gradient for effective milk elimination. The increased volume of the milk chamber of the collector does not provide the indicated conditions, therefore it is acceptable for intensive milking. At the same time, the higher intensity of milk yield is associated with a lower flow rate of milk in the milk tube. Reduction of the structural volume of the milk chamber of the collector leads to an increase in the magnitude of the increase in air pressure, which accelerates the flow of milk in the section of milk tubulure, regardless of its diameter. It is established that the flow rate of milk in the section of the milk pipe decreases with increasing diameter. The obtained mathematical model, which relates the intensity of milk yield to the technological parameters of the developed collector, depending on the milking regime. Rational relations between the structural volume of the milk chamber of the milking machine's collector and the diameter of the milk flexible pipe are established
