DEVELOPMENT AND RESEARCH OF MULTIFUNCTIONAL MILKING MACHINES BASED ON THE MILK FLOW INTENSITY BY UDDER SHARE'S CONTROL SENSOR

Abstract

The material on the milking machines' technical justification and research of udder each quarter's milk flow intensity controlling capable, mastitis diagnosing and in depending on milk flow intensity for the number of beats in the cycle changing is presented. The description of its electronic interaction with milking machine units, providing current milking control during milk excretion intensity from udder's each quarter and their physiological state is given. Experimentally confirmed the technical feasibility, technological and economic efficiency list of milking machines' functions performed by equipment's expanding with devices for milk flow intensity's monitoring. It is shown that the hybrid milking machine device operates in a more milk extraction's gentle mode in compared to the Duovac-300 one. According to investment projects' evaluation methodology, the calculations of modernized milking machines functioning in a cowshed with tie-free cows' keeping during milking in a milk pipeline's economic efficiency were carried out. The developed technical means introduction in a cowshed for 200 cows with tie-free cows' keeping pays off the initial costs and makes a profit during the first year of using. The expected DSO of the developed technical means ranges from 0,10-0,12 g. The confirmed economic effect of the tie-free cows' keeping in a cowshed with 200 heads of livestock's milking machines equipped with devices for milk flow intensity control using to 3319 thousand of rubles' prices in 2017 is amounted.
