Definitions

  • This invention concerns a milking machine according to the preamble of claim 1 and a method according to the preamble of claim 12. In a second aspect it also concerns a milking machine according to the preamble of claim 19 and a method according to the preamble of claim 25.
  • a prior art milking machine of this kind is operated by applying suction to the teats of a milking animal in order to extract the milk and transport it over a suction hose to a milk tank.
  • the teats must be relieved periodically from the sucking effect since continuous suction applied to the teats causes the accumulation of blood and lymph in the teat tips which restricts the milk canal, obstructs the milk flow and weakens the barrier against penetration of udder pathogens, and as a result thereof, causes udder health problems.
  • a restricted aperture has been provided in the suction path, for example in the suction hose close to the teatcup, or at the bottom of the teatcup, whereby the suction is relieved at occasions so as to promote milk flow in the suction hose.
  • dirt, insects etc. might at least partly plug the aperture, thereby restricting the inflow of air through the aperture and subsequently the desired milk flow.
  • a serious problem with plugged aperture is so called impact, resulting in risk of infections in the udder.
  • this is obtained by arranging a cleaning device, which provides a cleaning fluid flow for clearing the aperture from possible dirt, insects etc. between milking sequences.
  • the cleaning device applies a pressurised air jet against the aperture. This allows for having the cleaning device positioned at a greater distance from the aperture, whereby variations with respect to positioning is more tolerable.
  • the cleaning device is placed on the support structure which supports the teatcups in the rest position. This provides possibility of simple and secure installation of the cleaning device and accurate mutual positioning of the aperture with respect to the cleaning device .
  • rinsing water it is also possible to provide for rinsing water to penetrate the aperture in order to clear it from dirt etc. Preferably this is obtained during the ordinary back-flush rinsing between milking sequences, whereby no additional equipment has to be installed. It is only important to ensure that no rinsing water remains in the suction path after the flushing operation, and this may be obtained by using a valve, which obstructs the suction hose during rinsing so that rinsing water is not allowed to enter chosen portions of the suction hose.
  • the problems of the prior art are solved by providing gas supply to the aperture for supplying pressurised gas into the region including the suction hose close to the teatcup and the adjacent part of the teatcup.
  • the gas supply is controlled through a pressure regulator, which allows the farmer to adjust the gas supply as desired.
  • a pressure regulator which allows the farmer to adjust the gas supply as desired.
  • high FFA-value may call for restricted gas supply.
  • the gas supply is cut off when the pressure prevailing in the region in question is at a maximum. This way the gas supply pressure will not add to the pressure pulse from the teatcup initiated by the pulsator. Instead this arrangement reduces unwanted pressure fluctuations, which otherwise could go beyond prescribed allowed variations at a certain milk flow.
  • the vacuum variations are reduced whereby regulations are more easily fulfilled.
  • the volume of the lower part of the teatcup has in certain embodiments been given an added, relatively large volume. Both aspects of the invention allows reduction of said volume or even the elimination of it, thereby reducing occupied space and costs.
  • An important advantage of the second aspect of the invention is that a predetermined airflow may be obtained, since it is possible to optimize the flow parameters. Hereby more accurate milk flow measurement may be obtained since the operating conditions for a milk flow gauge included in the system are stabilized. This is an important advantage provided also by the second aspect of the invention.
  • Fig. 1 shows diagra matically a teatcup in its rest position on a support structure provided with a cleaning device according to the invention
  • Fig. 2 shows a detail of a first alternative cleaning device according to the invention
  • Fig. 3a shows diagrammatically a second alternative cleaning device
  • Fig 3b shows diagrammatically a further alternative cleaning device
  • Fig. 4 shows a section of a means defining an aperture
  • Fig. 5 shows diagrammatically an embodiment according to the second aspect of the invention.
  • Fig. 6 shows a section of a detail of the embodiment in Fig. 5.
  • reference numeral 1 generally indicates a support structure for a teatcup in its rest position between milking sequences.
  • the teatcup 2 rests hanging upside down between supporting elements and with a suction hose 3 and a pulsator hose 4 extending along each other, substantially vertically upwards.
  • a connector means 5 is installed including through channels (indicated with interrupted lines) for each of the hoses 3, 4 and connecting nipples extending upwardly and down- wardly (likewise indicated with interrupted lines) .
  • the connector means 5 is provided with a through aperture 6, which allows air from the outside to be sucked into the suction hose 3.
  • the support structure 1 supports a nozzle 7 for directing a pressurised air jet in the direction of the aperture 6.
  • the pressurised air supplied to the nozzle 7 is preferably an intermittent flow and for example such that air is blown immediately after one milking sequence and immediately before the following milking sequence. This because of the possibility of removing "soft" dirt before it has dried and hardened, and in order, as late as possible, to remove possible insects or dirt, which might potentially plug the aperture 6 , and has reached the aperture during the resting period.
  • the air jet emanating from the nozzle 7 is indicated with 8.
  • the cleaning device comprises a suction nozzle 9, which is positioned such that there is a relatively short distance between the aperture 6 and the suction nozzle 9 during the resting period for the corresponding teatcup.
  • Suction applied to the suction nozzle 9 may be controlled similarly to what has been said above with respect to the pressurised air nozzle in Fig. 1.
  • FIG. 3a A second alternative with respect to a cleaning device for cleaning the aperture is shown in Fig. 3a, whereby a rinsing device is indicated with 10.
  • This rinsing device is preferably the ordinary back-flush rinsing device intended to periodically back-flush and rinse the teatcup between milking sequences.
  • a rinsing water pressure of a chosen magnitude and by assuring that there is a counter pressure prevailing in the suction hose, a flushing effect through a back flush nozzle 11 will occur through the aperture 6, effectively removing dirt or insects.
  • 13 indicates a means, such as a valve, for preventing back- flush water to flow further towards the milk tank (not shown here) in the suction hose.
  • FIG. 3b A further alternative with respect to a cleaning device for cleaning the aperture is shown in Fig. 3b.
  • This cleaning device is preferably the ordinary back-flush rinsing device which in this case is equipped with means for subjecting the suction hose to a pressurised gas.
  • a pressure of a chosen magnitude By providing a pressure of a chosen magnitude and by assuring an at least essentially tight seal in the suction hose, a cleaning effect will occur through the aperture 6, for removing dirt or insects. This is obtained by gas introduced through the back flush or rinsing nozzle 11.
  • an air pressure supply is connected at 30 to the rinse water hose.
  • the suction hose 3 is provided with a shut off valve 32 for maintaining tightness in the region of the teatcup.
  • the shut off valve 32 is pressure controlled through tube 33, which is connected to the suction hose 3 upstream the shut off valve 32.
  • Cleaning by pressurising the suction hose may also be achieved otherwise, even if the embodiment according to fig 3b is preferred in this respect.
  • air pressure may be applied by an arrangement (not shown) separate from the rinsing equipment.
  • FIG 4 shows an insert 14 in a wall portion 15 of a connector means, an enlargement of a teatcup or the like.
  • the insert 14 is intended to be permanently fastened in a through hole in the wall so as to define an aperture 16 having in this case a widening cross section along, here, a conical inner surface
  • the cleaning fluid is intended to flow in the direction to the left, arrow F, for efficient cleaning effect. Also other appearances of the aperture are of course possible.
  • the cleaning device may be arranged otherwise and for other positions of an aperture similar to the shown aperture.
  • the aperture and the corresponding cleaning device may be positioned with respect to a common claw included in a cluster type construction including plural teatcups .
  • Figs 5 and 6 show an embodiment according to the second aspect of the invention.
  • air under pressure is supplied to the aperture 23 through a thin tube 18 which is drawn inside the pulsator hose 4.
  • the tube 18 is thus connected to the aperture 23 in the suction hose 3 at its first end.
  • the tube is lead out from the pulsator hose and is connected to a pressure regulator which preferably is adjustable so as to allow the farmer to precision control, for example with a knob 21, the amount of air admitted into the region of the aperture 23 of the suction hose and the teatcup.
  • the provision of the regulator 20 allows the operator to adjust the air supply if for example too high vacuum fluctuations in the suction hose have been observed or/and if the FFA-value is elevated. The latter may depend on too much air in the system.
  • the pressure regulator is fed over a pipe 22 from a (not shown) air pump which may provide an air pressure of, as an example, 6 bar.
  • the pressure regulator in stead of being manually operable, is controlled by means of an automatic control system which accounts for pulsator operation, pressure prevailing inside hose 4 etc. and sends signals to the regulator as a response to sensed conditions.
  • an automatic control system is computer controlled.
  • the aspect according to figs 5 and 6 makes it possible to supply clean air, as an example filtered outside air, or gas having a chosen composition. This way it is avoided that undesired gases, such as ammonia, generally being present inside the stable building, enters the system.
  • the tube 18 may be drawn outside the pulsator hose and extend therealong. Also other ways of placing a conduit separately, outside the pulsator hose, for supplying gas to aperture 23 are possible.
  • the entry of the tube 18 into the suction hose may also be arranged otherwise.
  • the aperture and the corresponding device for supply of gas may be positioned with respect to a common claw included in a cluster type construction including plural teatcups.
