A cow milking equipment comprises a rotable annular platform continuously rotated at a constant speed by a suitable motor and is provided with a plurality of stall angulated relative to a radial direction, for accomodating a cow that is to be milked, so as to enable the animal to enter and exit from the stall always passing over the outer peripheral edge of the platform.

A duct under partial vacuum leads mlk from the teat cup cluster and creates a milking milk therein, the duct having a regulating valve operable to vary the milking vacuum. A device for sensing changes in the rate of milk flow through this duct is connected to control means for operating the regulating valve to decrease the milking vacuum from a working value to an idling value in response to a decrease in the milk flow rate and in increase the milking vacuum from an idling to a working value in ...

A teat cup milking inflation is disclosed, said inflation being constructed from a natural or synthetic rubber material or from an elastomeric plastics material and having an integral flexible and resilient collar portion with a tapered feathered inner edge portion surrounding the mouth of the inflation. The tapered edge portion of the collar has a flat upper edge portion which can lie flat on the surface of an animal's teat when the inflation is engaged thereon, the collar being flexed inwardly...

A milking system is disclosed having a stationary circular base upon which cows being milked and fed are guided around by a circular framework having a center of rotation about a pipe located at the center of the framework. The pipe serves the purpose of guiding the framework in a horizontal direction, and roller bearings are provided near the periphery of the framework for supporting the framework. The framework is rotated by a chain which is wrapped around the framework and driven by an electr...

A milking machine installation having a rotatable annular raised platform for carrying a number of cows with provision for feeding the cows while they are being milked by a milking machine mounted on the inside of the platform controlled by an operative positioned in the center of the installation, the cows remaining on the platform between a boarding position and an alighting position which takes them for substantially a full turn of the platform.

A milking parlor apparatus and method for milking large numbers of cows using a pair of batch loaded reciprocating shuttling platforms in which one platform is batch loaded and moved to a milking station where the cows are milked while a second parallel platform is being loaded. The second platform is moved to the milking station and the first platform returned to the original loading station and unloaded and reloaded, thereby delivering a continuous supply of cattle for milking. The milking sta...

A milk flow indicator is inserted in the pipeline through which the liners of the teat cups deliver milk to a vessel maintained under vacuum; and control means are operatively connected to this indicator for varying the vacuum in the vessel in response to changes in the milk flow in the pipeline, the control means acting to reduce the vacuum in response to substantial cessation of the milk flow. Preferably, the flow indicator is also arranged to vary a characteristic of the pulsations to which t...

Milking apparatus for dairies in which cows are supported during milking on vertically movable platforms, the entry area to these platforms being elevated relative to the area of exit from the platforms, the difference in height between these levels enabling an operator to work at the exit side of the milking positions and to avoid bending when preparing the cows for milking.

The invention relates to milking apparatus in which the milk line and droppers, which convey milk under vacuum from teat-cup clusters to a receiving jar, are enclosed over their major length in a water-jacket through which water is directed in a direction contrary to the flow of milk. In this way the milk is pre-cooled before it is received in the receiving jar and frothing of the milk in the receiving jar is reduced so eliminating contamination of the vacuum line by froth. The water jacket is p...

A milking machine (1) comprises at least one teatcup (2) having a teatcup liner (4) and a pulsation chamber (5), a first pressure source (14) for generating a first pressure, a second pressure source (9) for generating a sub-atmospheric second pressure, which is lower than the first pressure, and conduit means (12, 15, 13) for transmitting the first pressure and the second pressure, respectively to the pulsation chamber (5). A pulsator (11) is provided for alternately connecting the first pressu...
