| description | One of the objectives of dairy farming is to further increase the rate of milk production by increasing the milk productivity of cows. The most important reserve for increasing milk productivity is the use of milking equipment that best suits animal physiology, as well as its proper selection and operation. The analysis of existing milking device designs allowed to draw a conclusion that one of their main drawbacks is an extremely hard influence on udder receptors and consequently inhibition of milking reflex, which results in the decrease of milking intensity of a cow and in the decrease of milk yield. It is established that the most responsible element of the milking machine is milking cups equipped with teat tubes, which directly contact with an animal and are the actuating mechanisms. The research of deflection of symmetrical working part of a teat tube is based on the known principles of liquid (gas) and solid mechanics, theory of elasticity and resistance of materials, as well as of mathematical analysis. The equation of the maximum radial deflection of the working part of teat tube of the milking machine which allows to determine the interrelation of the deformation with mechanical characteristics of a used material, the basic constructive and dynamic parameters is derived. Besides, the given equation allows to determine the minimum necessary height of the working part of the teat tube with the minimum allowable thickness for creation of the wave effect of extrusion from sucker to diverter in a squeezing stroke while designing the milking machine with the squeezing effect. |
