MILK METERING AND/OR MILK CONTROLLING DEVICE AND METHOD FOR MEASURING THE QUANTITY OF MILK OF EACH COW DURING THE MILKING OPERATION, OR FOR CONTROLLING THE MILK FLOW DURING THE MILKING OPERATION BY USING THE DEVICE

摘要

1. A milk metering and/or milk controlling device for milking plants for measuring the quantity of milk from a cow during a milking operation, or for controlling the milk flow during the milking operation, comprising a deaerating chamber (1), which is connected to a milk supply line (2) and may be acted on by an underpressure ; a measuring chamber (3) comprising a milk outlet (5) and connected via a closable milk inlet opening (4) to the deaerating chamber (1) and in which a measuring device is arranged having a magnetic float (10) guided on a pipe (13) and at least one switching contact (9) operated by the float (10) in dependence on the level of the milk ; and a counting and/or indicating device (12) which receives pulses from the switching contact or contacts, characterized in that the pipe (13) is constructed as an aeration pipe and in that the magnetic float (10) is guided on an aeration pipe (13) comprising an aeration valve (14) and ending at a distance below the milk inlet opening, which aeration pipe (13) movably carries, in the measuring chamber (3) at the air outlet end (13a), a separating valve (15) which releases the milk inlet opening (4) when there is underpressure in both chambers (1, 3) and closes said opening (4) during aeration.
