Melkmaschinen, bei denen eine Vereinigung von mechanischer Bearbeitung des Euters und Saugen benutzt wird, sind häufig so eingerichtet, daß die mechanische Bearbeitung der Zitzen und das Saugen gleichzeitig erfolgen. . Dies ist indes unzweckmäßig, weil die Zitzen während der mechanischen Bearbeitung von der Verbindung mit dem inneren Teile des Euters ganz oder teilweise abgeschlossen sind und dasMilking machines in which a union of mechanical processing of the udder and Sucking is used are often set up so that the mechanical working of the teats and suction take place at the same time. . However, this is inexpedient because the teats during the mechanical processing from the connection with the inner part of the udder entirely or are partially completed and that

ίο Saugen infolgedessen wenig wirksam wird.ίο As a result, suction is not very effective.

Die Erfindung betrifft eine solche Vereinigung von mechanischer Bearbeitung der Zitzen und Saugen, daß letzteres in den Zwischenzeiten, wenn keine mechanische Beeinflussung der Zitzen stattfindet, erfolgt, wodurch das Saugen auf das ganze Euter wirkt und die Milch in die Zitzen hinabzieht. Die mechanische Bearbeitung der Zitzen erfolgt in bekannter Weise vermittels eines oder mehrerer Luftkissen, die in den Zitzenbechern angebracht sind und wechselweise mit Luft gefüllt und von Luft entleert werden, während der Erfindung gemäß das Saugen in der Weise herbeigeführt wird, daß unmittelbar vor dem Entleeren des bzw. der Kissen ein Ventil in der Milchleitung geschlossen wird, so daß beim Entleeren des oder der Kissen Luftverdünnung in den Zitzenbechern und dadurch Saugen erzeugt wird.The invention relates to such a union of mechanical working of the teats and Suck that latter in the meantime when there is no mechanical influence on the Teat takes place, takes place, whereby the sucking acts on the whole udder and the milk in the Pulls teats down. The teats are mechanically processed in a known manner one or more air cushions that are mounted in the teat cups and alternately be filled with air and deflated by air, while the invention according to the Sucking is brought about in such a way that immediately before emptying the or the Pillow a valve in the milk line is closed, so that when emptying the pillow or pillows Air dilution in the teat cups and thereby suction is created.

Auf der Zeichnung ist die Erfindung in zwei Ausführungsformen dargestellt.In the drawing, the invention is shown in two embodiments.

Fig. ι ist ein senkrechter Schnitt der einen Ausführungsform.Fig. Ι is a vertical section of one embodiment.

Fig. 2 zeigt diese Ausführungsform in Oberansicht. Fig. 2 shows this embodiment in a top view.

Fig. 3 ist ein senkrechter Schnitt der zweiten Ausführungsform.Fig. 3 is a vertical section of the second embodiment.

In dem Zitzenbecher 1 (Fig. i)sindumdieZitze2 zwei Paar Luftkissen 3, 4 bzw. 5, 6 vorgesehen, von denen die Kissen 4 und 5 und die Kissen 3 und 6 dieselbe Gestalt. haben und die letzteren hinter den ersteren angeordnet sind. Die Kissen sind vermittels Bänder an dem Bechergehäuse aufgehängt oder mit diesem mittels elastischer Gummiwände verbunden. Die Kissen 4 und 5 tragen federnde Stangen 7 und 8, die in Führungen 9 und 10 so verschiebbar sind, daß die Kissen 4 und 5 sich der Zitze nähern, wenn die Stangen aufwärtsbewegt werden.In the teat cup 1 (Fig. I) there are around the teat 2 two pairs of air cushions 3, 4 and 5, 6 are provided, of which the cushions 4 and 5 and the cushions 3 and 6 the same shape. and the latter are arranged behind the former. The pillows are suspended by means of straps on the cup housing or with this by means of elastic Rubber walls connected. The cushions 4 and 5 carry resilient rods 7 and 8 in guides 9 and 10 are displaceable so that the cushions 4 and 5 approach the teat when the Rods are moved upwards.

Sämtliche Kissen stehen durch Rohrleitungen, in denen Rückschlagventile 11,12,13 angebracht sind, mit einem Luftkompressor in Verbindung. Wird letzterer in Betrieb gesetzt, so öffnen sich zuerst die Ventile 11, und die Luft füllt die Kissen 4 und 5. Sobald in diesen ein bestimmter Druck erreicht ist, schließen sich die Ventile 12, und die Ventile 13 öffnen sich, so daß die Luft ■ in die Kissen 3 und 6 strömt. Hierdurch werden die inneren Kissen gegen die Zitze gepreßt und drücken die Milch aus derselben - heraus. Um eine stärkere Pressung zu erzielen, werden die Stangen 7 und 8 aufwärtsbewegt, was z. B. in der Weise geschehen kann, daß dieselben an ihren unteren Enden mit einem durch Druckluft hin und her bewegten Schieber 0. dgl. verbunden werden.All cushions are through pipelines in which check valves 11,12,13 are attached are connected to an air compressor. If the latter is put into operation, they open first the valves 11, and the air fills the Cushions 4 and 5. As soon as a certain pressure is reached in these, the valves 12 close, and the valves 13 open so that the air ■ flows into the cushions 3 and 6. This will be the inner cushions pressed against the teat and squeeze the milk out of it. In order to achieve a stronger pressure, the rods 7 and 8 are moved upwards, which z. B. can be done in such a way that the same at their lower ends with a slide moved back and forth by compressed air 0. The like. Connected will.

Die Luftkissen stehen ferner durch Rohre mit einer Vakuumleitung 18 in Verbindung. Wenn die Kissen genügend gefüllt sind, wird der Korn-.The air cushions are also connected to a vacuum line 18 by pipes. if The pillows are filled enough, the grain becomes.

Claims

pressor is out of operation and the vacuum pump or the like connected to line 18. put into operation. As a result, the air is sucked out of the pillows and theirs

.5 Scope significantly reduced. As soon as this reduction in size begins, it closes one which is arranged in the outlet connection of the teat cup and is subject to spring action Valve 14, and air dilution takes place in the teat cup, which has the consequence that suction is exerted on the teats. Since the suction only after the withdrawal When the air cushion comes from the teat, it is in contact with the inner ones during sucking Parts of the udder in connection and can easily fill up with milk.

In order to bring about an air dilution of sufficient size, it goes without saying necessary that the teat cup connects to the udder in an airtight manner. this will expediently effected in the usual way in that the upper edge 15 of the teat cup with a hollow rubber plate 16 is provided, the cavity 17 of which is provided with a special vacuum line, in which there is a constant vacuum. A number of fine holes 19 are provided on the upper side of this plate, which cause the plate, as soon as they, provided that in the cavities 17 There is air dilution, is pressed against the udder, adheres to the udder and one creates a completely airtight seal. In the second embodiment shown in FIG the device four air cushions 21, 20, 24 and 27 are provided, of which the smaller pillows 20, 24 and 27 are behind the large pillow 21, and the pillow 20 with it the cushion 21 is connected. Each of the cushions 20, 24, 27 is through a pipe with each a chamber of a container divided by partitions. The partitions are provided with valves 22, 25, and the container chambers are connected to a pipe in connection, which is connected to a compressor and a vacuum pump, with between of the latter and the lower chambers valves 28, 29 are switched on. Will be dated When compressed air is pressed into the line by the compressor, the cushion 20 is first in addition to the inner cushion 21 connected to it, it is filled with air. Once the Pressure in the cushion 20, 21 has reached a certain level, the valve 22 opens, and the Compressed air passes through a line 23 and the cushion 24. Is the pressure in this cushion has risen to a certain height, the valve 25 opens and the compressed air flows through a line 26 into the pillow 27.! So it's gradually going from top to bottom progressive pressure exerted on the teat after this first through the upper cushion locked by the udder.

When milking cows with very short teats, the cushion 27 can thereby be out of action set. be that the valve 25 by regulating the tension of the acting thereon Spring or otherwise is so heavily loaded that the compressed air does not open the same able. When the main line is connected to the vacuum pump, the valves 28 and 29 open simultaneously and the air escapes through them from all Pillow, so that, at the same time, the not shown, in the outlet nozzle of the cup arranged valve 'closes, a suction is exerted on the teat.

The pressure exerted by the air cushions can be regulated by means of the valves 22 and 25. They are more stressed for cows that are difficult to milk and for cows that are easy to milk less strong.

Pa τ ent-A ν saying:

Milking cup with air cushions influencing the teats and one arranged in the milk line Valve, characterized in that this valve is arranged in such a way that it is due to the at the beginning of emptying the air cushion in the teat cup generated air dilution is closed, so that with the further emptying of the air cushions a stronger air dilution in the Cup is created and suction is applied to the teat.
