Beim Anbau fast aller Pflanzen werden chemische Mittel angewendet, um die Pflanzen gegen Pilzkrankheit, Insekten und Unkraut zu schützen. Diese Schutzmittel für Pflanzen werden auf verschiedene Weise auf die Pflanzen aufgebracht, meistens über die Pflanzen verspritzt, und zwar mittels eines starken Luftstroms, der das flüssige Schutzmittel in kleine Tropfen aufteilt und sie über die Pflanzen verteilt. In the cultivation of almost all plants, chemical agents are used to protect the plants against fungal diseases, Protect insects and weeds. These protectants for plants are used in different ways Applied to the plants in a way, mostly sprayed over the plants, by means of a strong Air flow that breaks up the liquid protective agent into small droplets and distributes them over the plants.

Die Erfindung bezieht sich auf einen Sprühkopf ίο zum Verspritzen von Schutzflüssigkeiten für Pflanzen mit einer in einem Luftleitrohr angeordneten venturiartigen Sprühdüse, der die Flüssigkeit nahe dem engsten Düsenquerschnitt von seitwärts durch Rohre zugeführt wird.The invention relates to a spray head ίο for spraying protective liquids for plants with an arranged in an air duct venturi-like spray nozzle, which the liquid near the narrowest nozzle cross-section from sideways through Pipes is fed.

Zweck der Erfindung ist es, das Einsetzen einer solchen Düse in das Luftleitrohr zu erleichtern.The purpose of the invention is to facilitate the insertion of such a nozzle into the air duct.

Erfindungsgemäß liegen die Mündungen der die Flüssigkeit zur Düse führenden Rohre in Richtung des Gebläsestromes vor einem sich verengenden Teil ao des Luftleitrohres, und die Rohre sind durch elliptische Ausschnitte in dem sich verengenden Teil des Luftleitrohres nach außen geführt.According to the invention, the mouths of the tubes leading the liquid to the nozzle lie in the direction of the blower flow in front of a narrowing part ao of the air guide tube, and the tubes are elliptical Cutouts in the narrowing part of the air guide tube led to the outside.

Die Zeichnung zeigt ein Ausführungsbeispiel eines erfindungsgemäßen Sprühkopfes. Die Mündung 1 der Düse 4 liegt in dem sich verengenden Teil 6 des von einem Gebläse gespeisten Luftleitrohres 7, 6, 5. Die Schutzflüssigkeit wird durch ein oder mehrere Rohre 2 von den Seiten her in die Düse 4 eingeführt. Wie mit den Pfeilen 8 angedeutet, strömt Luft durch das Luftleitrohr und durch die Düse und führt die Flüssigkeit entlang den Innenwänden der Düse mit sich.The drawing shows an embodiment of a spray head according to the invention. The mouth 1 the nozzle 4 lies in the narrowing part 6 of the air guide tube 7, 6, 5 fed by a fan. The protective liquid is introduced into the nozzle 4 from the sides through one or more tubes 2. As indicated by the arrows 8, air flows through the air guide tube and through the nozzle and leads the Liquid along the inside walls of the nozzle.

In dem sich verengenden Teil 6 befinden sich elliptische Ausschnitte, durch die die Rohre 2 beim Einsetzen der Düse hindurchgeführt werden.In the narrowing part 6 there are elliptical cutouts through which the tubes 2 when Insertion of the nozzle can be passed through.
