TEAT CUP OF SQUEEZING PRINCIPLE OF ACTION Russian patent published in 2013 - IPC A01J5/04 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. The proposed teat cup comprises a housing 1 with a teat cup liner 19, a deformer 18 of the teat cup liner 19 kinematically connected to the cover 4 of a large bellows 3, a small bellows 5. The deformer 18 of the teat cup liner 19 is made in the form of rollers 20 mounted on axes 21 which are in turn attached to the levers 22 by hinges 23 mounted on the frame 24. This frame 24 is connected by rigid rods 25 with a cover 4 of the large bellows 3. The cover 10 of the small bellows 5 by the rods 26 is connected to the axes 21 of the rollers 20 with the ability of their interaction with the teat cup liner 19. In the bottom 2 of the housing 1 an outer tube 6 is mounted, which comprises a cylindrical part 7 and an inner sample 8. The lower end of the outer tube 6 is connected through the three-way valve 34 to a source of pulsating vacuum-gauge pressure. In the outer tube 6, an inner tube 9 is mounted coaxially and movably, which upper end is mounted coaxially and movably in the cover 4 of the large bellows 3 and is attached to the cover 10 of the small bellows 5. The cavity 11, which is formed by the outer wall of the inner tube 9 and the inner wall of the outer tube 6 at the area of inner sample 8, with its opening 12 is connected to the cavity 13 of the large bellows 3. In the inner tube 9 an opening 14 is provided which is overlapped in the initial position by the cylindrical part 7 of the outer tube 6, and the opening 15 with which the cavity 16 of the inner tube 9 is connected to the cavity 17 of the small bellows 5. The cavity 31 of the housing 1 of the teat cup with the pipe 32 is connected through the pressure regulator 23 to the source of vacuum-gauge pressure. In the milk pipe 28 a gauged orifice 29 is made for access of air in its cavity 30.

EFFECT: invention provides a reduction in the incidence of mastitis in cows by 10-12%.
