Abstract
Apparatus for use in the machine milking of animals including a chamber wh is connectable to the teat cups of a milking machine. A sensing arrangement associated with the chamber permits the volume of milk within the chamber to be sensed and control equipment is coupled with the sensing arrangement so as to be operable in response to a determined volume of milk within the chamber being sensed. A valve is operable in response to the control equipment. Accordingly, the apparatus can be connected to a milk transport system to enable milk to pass from the chamber through the valve and into the milk transport system.
Claims19
Apparatus for use in the machine milking of animals comprising a milking receiving chamber connectable to the teat cups of a milking machine and connectable to a milking vacuum source, sensing means associated with said chamber, said sensing means, during milking of an animal, sensing a presence of a volume of milk equal to or greater than a predetermined volume, a milk outlet through which milk from the milk receiving chamber can flow into an evacuated milk transport means, valve means which is operative between open and closed positions to control milk flow through or from said milk outlet and control means for controlling the opening and closing of said valve means, the control means being operative to close the valve means each time said sensing means senses a reduction to said predetermined volume and operative to open said valve means when, following closure of the valve means the milk contained within the chamber has increased to a volume greater than said predetermined volume.
Apparatus for machine milking an animal comprising a teat cup cluster coupled to a milk receiving chamber, a milking vacuum means connected via a claw vacuum line to said chamber, said chamber being connected with evacuated milk transport means, said milk transport means being separate from said vacuum milking means, sensing means associated with said chamber said sensing means, during milking of an animal, sensing a presence of a volume of milk equal to or greater than a predetermined volume, a milk outlet through which milk from the milk receiving chamber can flow into a milk transport means, valve means which is operative between open and closed positions to control milk flow through or from said milk outlet and control means for controlling the opening and closing of said valve means, the control means being operative to close the valve means each time said sensing means senses a reduction to said predetermined volume and operative to open said valve means when, following closure of the valve means the milk contained within the chamber has increased to a volume greater than said predetermined volume.
