COW UDDER SIMULATOR Russian patent published in 1997 - IPC

FIELD: agriculture, in particular, stand equipment for analyzing manual and machined cow milking parameters. SUBSTANCE: cow udder simulator has bowl-shaped casing 1 with four flexible teats 4 and control and regulation system having power units 5, unit 6 adapted for controlling parameters of outer effects acting upon cow udder and provided with outer effect parameter sensors, teat sphincter tone simulating unit 7, unit 8 for determining pressure in cow udder, milk admitting unit 9 and unit 10 for detecting reaction of cow on physical parameter of outer biological object 10. Casing 1 is manufactured from three rubber layers 2. Unit 10 is formed as unit simulating reaction of cow to milker' odor. Outer effect parameter sensors 3 are made in the form of devices sensing mechanical action of milker's hands, such as slight smoothing, massaging and mashing of cow's udder. These devices are mounted on surface of each rubber layer of casing 1. Teats 4 are made cylindrical, with two through discharge holes at apex of each teat and spherical resilient chamber adapted for closing holes and communicated with pressure source of unit 7. EFFECT: increased efficiency in training milking operations, simplified construction and enhanced reliability in operation. 2 cl, 2 dwg
