APPARATUS FOR PNEUMATIC MASSAGE OF HEIFER UDDER Russian patent published in 1999 - IPC

Abstract RU 2136146 C1

FIELD: animal farming, in particular, equipment for massaging of cow and heifer udder. SUBSTANCE: apparatus has bell-shaped device, spring-loaded plate positioned within bell-shaped device and provided with deforming members, gage openings and throttle. Massaging bell-shaped device is divided into two cavities, each connected to vacuumizer and adapted for embracing front and rear parts of udder. Throttle is formed as branch pipe with effective section regulated by adjusting screw. Gage opening is adapted for communicating inner cavity of bell-shaped device with atmosphere and provided with ball valve which is cut off by spring, when it is in closed state. Apparatus is further provided with corrugated teat liners. Space under teat is communicated with bell-shaped cavity via gage channel. Atmospheric air supply is restricted by spring-loaded ball valve. Lower ends of teat liners are connected with ball-shaped device through membranes. Such construction allows different parts of animal udder to be massaged for variable time. EFFECT: increased efficiency and simplified construction. 5 cl, 1 dwg
