Definitions

  • the invention relates to a milking device with four teat cups and with a measuring device for determining at least one milk parameter.
  • milking devices A large number of milking devices are known to date, with the aid of which milk can be obtained more or less automatically.
  • Such milking devices usually have teat cups which can be attached, for example, to the four teats of a cow udder, in order then to remove milk from the cow with the aid of pulsating movements or with the aid of negative pressure in the teat cups.
  • teat cups which can be attached, for example, to the four teats of a cow udder, in order then to remove milk from the cow with the aid of pulsating movements or with the aid of negative pressure in the teat cups.
  • the milk is examined for every milking process to determine whether it is noticeable. This test allows conclusions to be drawn about udder health.
  • the object is achieved in that the measuring device of the milking device of the type mentioned has a measuring chamber into which the milk flows from the teat cups. Each foremilk of the individual teats is introduced and checked in succession in the one measuring chamber.
  • the material outlay for this one measuring chamber is relatively small, so that there is a considerable saving compared to known devices which, for example, are equipped with four separate measuring chambers.
  • the second teat cup is attached to the corresponding teat, its pulsator can be switched on to obtain the second foremilk sample.
  • the second foremilk sample therefore arrives in the measuring chamber after the first foremilk sample and due to the blow-out, and can be tested individually as prescribed.
  • the pre-milking test of the third and fourth teat is carried out accordingly.
  • the measuring chamber has two subspaces, one of which serves as a measuring space and the other as an overflow space.
  • the measuring space is preferably located below the overflow space.
  • a measuring cell is provided in the measuring chamber, which preferably contains devices for measuring the electrical resistance of the milk.
  • the measuring cell is arranged in the lower region of the measuring space.
  • the measuring chamber preferably has a fill level sensor, which is preferably arranged in the upper region of the measuring space.
  • the measuring chamber of the preferred embodiment has inlet openings which are connected directly to the teat cups via milk lines and are preferably located in the overflow space.
  • the preferred embodiment has at least two outlet openings, one of which is located at the lowest point in the measuring space and the other in the overflow space. The outlet openings are preferably followed by lines which lead to a common line outside the measuring chamber and which can preferably be shut off between the common line and the measuring chamber.
  • the measuring chamber in the preferred embodiment has means for completely emptying and cleaning the measuring chamber and a control device which is used to fill the measuring chamber with the foremilk of a teat, for subsequent measurement and for finally emptying and cleaning the measuring chamber and for repeating these steps for the Foremilk serves other teats.
  • FIG. 2 shows a measuring chamber according to FIG. 1 in an enlarged view.
  • a milking device for cows for example, consists of many components, some of which work with the measuring chamber 10 are shown in FIG.
  • essential components are hose lines 1 2, which lead to four teat cups 14.
  • the teat cups 14 are connected to four teats 16 in the illustration.
  • the device 18 further shown serves to retract and extend the hoses and is of no significance for the invention.
  • the tubes 1 2 between the teat cups 1 4 and the measuring chamber 1 0 are not interrupted, for example by valves or in the device 1 8.
  • FIG. 2 is a detail from FIG. 1 and essentially shows the measuring chamber 1 0.
  • the measuring chamber 10 is shown in perspective and partly in section, so that its essential features become clear.
  • the measuring chamber 10 comprises two subspaces, namely the measuring space 20, which is shown in section in the lower area of the figure, and an overflow space 22, which is shown closed.
  • the overflow space 22 has four inlet openings 24, into which the hose lines 1 2, which come from the teat cups 14, open.
  • the measuring space 20 is arranged below the overflow space 22.
  • the upper side of this measuring chamber 20 is open to the overflow chamber 22 and has two openings in its lower region, of which the first opening 26 serves to receive a measuring cell 28 and of which the second opening is connected to a first line 30, which can be shut off with a valve 32.
  • the common line 38 there is at least occasionally a vacuum which is necessary for sucking off the milk.
  • this negative pressure is applied to the measuring chamber 10 by first opening the valve 36.
  • the teat cups 14 pulsate, so that milk is withdrawn from the teats 16, which is first sucked into the overflow space 22 due to the negative pressure in the measuring chamber 10.
  • the milk flows through the opening between the overflow space 22 and the measuring space 20 in the bottom of the overflow space 22 into the measuring space 20.
  • the milk collects as long as the valve 32 is shut off, so that the milk does not pass the measuring space 20 through the first Line 30 can leave.
  • no milk is sucked off through the line 34, since this does not start at the bottom of the overflow space 22, but somewhat higher.
  • the valve 32 remains closed and the valve 36 remains open, while the teat cup connected to the teat from which the foremilk sample is to be taken pulsates. This state is maintained until the measuring space 20 is sufficiently filled to avoid incorrect measurements.
  • a sufficient fill level is indicated in FIG. 2.
  • the measuring chamber 20 has a fill level sensor (not shown) in its upper region.
  • the corresponding teat cup 14 stops pulsating, at the same time the valve 36 is shut off, so that no further milk is removed from the corresponding teat.
  • a measurement of the specific resistance of the milk in the measuring space 20 is then carried out with the aid of the measuring cell 28. If the milk is noticeable in this measurement, this allows conclusions to be drawn about poor udder health. The milk subsequently milked is then not collected for human consumption.
  • the valve 32 When the milk test for a teat is complete, the valve 32 is opened and the milk is sucked out of the measuring space 20.
  • a ventilation valve of the measuring chamber 10 opening into the overflow space 22 can be opened at the same time.
  • the ventilation valve is not shown in the figure.
  • the valve 32 After the entire measuring chamber 10 has been completely emptied, the valve 32 is closed again, the valve 36 is opened and the pulsator in the teat cup is started for the next teat.
  • the next foremilk sample is then obtained in the same way as the previous one and, because the measuring chamber is completely empty, does not come into contact with the previous foremilk sample between each sampling.
  • both valves 32 and 36 are opened and the pulsators of all four teat cups 1 4 are started.
  • the milk now flows through all four hoses 1 2 simultaneously into the measuring chamber 10 and there through the overflow chamber 22 and the measuring chamber 20, passes the valves 36 and 32 and is finally sucked off through the common line 38.
  • the common line 38 is connected to a milk quantity measuring device, by means of which the milk flow is checked and the milking process is stopped can, as soon as the milk flow subsides.
  • the milk is finally either collected in a container containing milk approved for human consumption or in a container for unsuitable milk for human consumption.
  • Valves serve to divert the milk into one of the two containers.
