Description

den speziellen Korken 4, der zu der Ausrüstung gehört, ausgewechselt werden.the special cork 4, which is part of the equipment, can be changed.

Lediglich die Fallhöhe der Flüssigkeit wird dazu benutzt, den Flüssigkeitsstrom in die Maschine zu bekommen, die Verteilung der Flüssigkeit 5 erfolgt direkt in dem Massen- und Luftstrom in der Maschine. Only the height of fall of the liquid is used to increase the flow of liquid into the machine get, the distribution of the liquid 5 takes place directly in the mass and air flow in the machine.

Damit der Flüssigkeitsstrom nicht mit dem Flüssigkeitsniveau in der Kanne 1 variiert, ist bei der erfindungsgemäßen Vorrichtung dadurch ein automatischer Druckregler vorgesehen, daß durch einen geeigneten dünnen Luftschlauch 6 Luft zugeführt wird. Für diese Ausrüstung paßt ein Schlauch mit einem inneren Durchmesser von 3,5 mm. Versuche haben gezeigt, daß dieser Durchmesser innerhalb enger Grenzen gehalten werden muß.So that the liquid flow does not vary with the liquid level in the jug 1, the inventive Device thereby provided an automatic pressure regulator that by a suitable air is supplied to the thin air hose 6. For this equipment one hose fits with one inner diameter of 3.5 mm. Tests have shown that this diameter is narrower within Limits must be kept.

Ebenfalls darf der die Flüssigkeit zu der Düse 8 führende Schlauch 7 nicht einen inneren Durchmesser haben, der größer als 8 mm ist. Wird er größer gemacht, entstehen Probleme mit Luftblasen in dem ao System, die den Flüssigkeitsstrom behindern können.Likewise, the hose 7 leading the liquid to the nozzle 8 must not have an inner diameter larger than 8 mm. If it is made larger, problems with air bubbles arise in the ao System that can obstruct the flow of liquid.

Der Flüssigkeitsstrom zu der Maschine muß während des Fahrens in Abhängigkeit davon, ob Massenstrom durch die Maschine geht oder nicht, geschlossen und geöffnet werden können. Früher wurde Schließen und öffnen des Flüssigkeitsstromes ausschließlich manuell durchgeführt. Die Erfindung ermöglicht daneben ein automatisches öffnen und Schließen des Flüssigkeitsstromes. Ein spezieller Fühler 9 wird in einer solchen Weise placiert, daß der Massenstrom in der Maschine selbst oder das stehende Erntegut auf dem Felde während des Erntens auf den betreffenden Fühler mit einer Kraft einwirkt, die auf ein Ventil 10 übertragen wird.The liquid flow to the machine must be during driving depending on whether mass flow going through the machine or not, can be closed and opened. It used to be Closing and opening of the liquid flow carried out exclusively manually. The invention enables next to it an automatic opening and closing of the liquid flow. A special one Sensor 9 is placed in such a way that the mass flow in the machine itself or the stationary Crop in the field during harvesting acts on the respective feeler with a force, which is transmitted to a valve 10.

Der Flüssigkeitsstrom wird schließlich durch eine Düse 8 aus Plastik in die Maschine eingeführt. Die Düse hat eine Bohrung schräg nach oben, damit der Massenstrom sie nicht verstopfen kann. Eine einfache Befestigungsvorrichtung, bestehend aus einer Haarnadelfeder 11, ermöglicht ein einfaches Anbringen der Düse von der Außenseite der Maschine her. Die Enden der Haarnadelfeder sind an der Maschinenwand mittels eines Schraubbolzens 12 befestigt und liegen mit ihren parallelen Schenkeln an den Anlageflächen auf jeder Seite der Düse 8 an. Der gebogene Teil der Feder ist derart erweitert, daß die gesamte Düse diesen Teil der Feder passieren kann, wenn der gebogene Teil und damit die Düse aus der öffnung in der Maschinenwand herausgezogen wird. Die pro Zeiteinheit zuzuführende Flüssigkeitsmenge kann dadurch geregelt werden, daß auf Düsen mit anderen Bohrungsdurchmessern übergegangen wird.The liquid stream is finally introduced into the machine through a nozzle 8 made of plastic. the The nozzle has a hole at an angle upwards so that the mass flow cannot clog it. A simple one Fastening device, consisting of a hairpin spring 11, enables simple attachment the nozzle from the outside of the machine. The ends of the hairpin spring are on the machine wall fastened by means of a screw bolt 12 and lie with their parallel legs on the contact surfaces on each side of the nozzle 8. The bent part of the spring is expanded so that the entire This part of the spring can pass through this nozzle when the bent part and thus the nozzle out of the opening in the machine wall is pulled out. The amount of liquid to be added per unit of time can be regulated by switching to nozzles with other bore diameters.
