MILKING DEVICE Russian patent published in 1994 - IPC

FIELD: agricultural engineering. SUBSTANCE: device has teat cups 1 and 2 for the front and rear udder lobes respectively, claw 6, and milk can 7. A vertical partition divides the can into chambers 9 and 10. Movable claw bottom 13 is provided with handle 32. Milk chamber 9 of the claw is in communication with air- operated member 24, and chamber 10 communicates with air-operated member 25. Part 18 of receiver 16 is open to air-operated member 24 and claw 6 via vacuum valve 29, and part 19 is open to air-operated member 25 and claw 6 via vacuum valve 29. Flexible ties 22 and 23 are provided with telescopic inserts. As the animal walks, expansion of air-operated members 24 and 25 followed by their contraction resulted in deeper vacuum in both parts 18 and 19 of the receiver. The animal comes to a halt, and the teat cups are put on the teats. Owing to vacuum under the teats they are squeezed from their bases to tips, and milk is taken as if it was sucked out by a calf. The rear upper lobes are "resting" while the front ones are in the suction phase, and vice versa. EFFECT: higher efficiency and convenience in operation. 7 cl, 2 dwg
