Das Aufbriwgen der Fremdenergie zum Verstellen des Steuerelements erfolgt dabei automatisch in Form von elektrischer, magnetischer, pneumatischer oder hydraulischer Energie. Das Steuerelement ist derart ausgebildet, dass, sobald es in eine einstellbare Steuerstellung gebracht wird, diese eingestellte Steuerstellung beibehält, ohne dass dem Steuerelement oder einem zur Verstellung des Steuerelements vorgesehenes Stellmittel Fremdenergie in Form von elektrischer, magnetischer, hydraulischer oder pneumatischer Energie zugeführt wird. Dies kann beispielsweise durch Reibschluss zwischen dem Steuerelement und der Düsenvorrichtung und/oder durch selbsthemmende Stellmittel, mit denen das Steuerelement verstellbar ist, erfolgen. Ein selbsthemmendes Stellmittel kann beispielsweise als eine mit dem Steuerelement verbundene Spindel ausgebildet sein, welche durch Verdrehen die Lage des Steuerelements verändert und im Stillstand selbsthemmend das Steuerelement in seiner Stellung hält. Die Düsenvorrichtung kann mit mehreren Kanälen ausgebildet sein, wovon wenigstens einer mit der Spritzleitung eines Spritzengestänges verbunden ist. Wenigstens ein weiterer Kanal führt zu einer an der Düsenvorrichtung angebrachten Düse, durch welche Spritzflüssigkeit ausgebracht werden kann. Die Düsenvorrichtung kann auch mit mehrere Düsen versehen sein, die gleichartig oder auch unterschiedlich ausgebildet sein können. Dabei können auch mehrere Kanäle die zu einer Düse führen oder auch mehrere Kanäle die zu verschiedenen Düsen führen in der Düsenvorrichtung ausgebildet sein. Durch die Verwendung mehrerer Düsen gleicher und/oder verschiedener Art können die Spritzmenge und/oder die Spitzstrahlform variiert und reguliert werden. Das Steuerelement ist zwischen dem mit der Spritzleitung der Spritzmaschine verbundenen Kanal und wenigstens einem mit einer Düse verbundenen Kanal angeordnet, so dass die jeweiligen Kanäle durch das Steuerelement miteinander verbindbar oder voneinander trennbar sind. Ferner ist es denkbar das Steuerelement derart auszubilden, dass Steuerstellungen einstellbar sind, in denen jeweils unterschiedliche Kanäle mit einem zu einer Spritzleitung führenden Kanal oder mehrere zu einer oder mehreren Düsen führende Kanäle gleichzeitig mit einem zu einer Spritzleitung führenden Kanal verbunden werden. Von Vorteil dabei ist, dass die an der Düsenvorrichtung angeschlossenen Düsen unterschiedliche Austrittsöffnungen aufweisen können und über das Steuerelement unterschiedliche Düsen automatisch anwählbar sind. Durch entsprechende Ausbildung des Steuerelements können auch mehrere der jeweiligen Kanäle zugleich mit einem mit der Spritzleitung verbundenen Kanal verbunden werden. Dabei sind verschiedene Schaltkombinationen der Düsen miteinander denkbar, so dass beispielsweise die Ausbringmenge durch Verstellen des Steuerelements regulierbar ist, indem ein oder zwei oder mehr Düsen gleichzeitig Spritzflüssigkeit ausbringen. Es ist denkbar, dass die von dem Steuerelement eingenommenen Steuerstellungen auch Steuerstellung aufweisen, in welcher der.Durchfluss zwischen zwei Kanälen reduzierbar ist, derart, dass in einer derartigenAccording to the invention comprises a nozzle device of the type mentioned, a housing part and an adjustable by foreign energy and can be brought into several control positions control to control the flow of a spray liquid from a spray line through a plurality formed in the housing part channels, wherein the control is designed such that it without supply dwelled by external energy in the control positions, wherein at least one connectable to the spray line of the spraying machine, a plurality of nozzles disposed on the housing part nozzle ports and a plurality of nozzles each connected to a nozzle connection are provided, and wherein the control in the housing part between the connectable to the spray line of the sprayer channel and is arranged connected to the respective one nozzle port channels, so that the respective channels are connected to each other by the control or separable from each other wherein a plurality of the housing il arranged nozzle ports and at least one to at least one nozzle port of the nozzle device leading channel are provided, and the control is arranged in the housing part between the connectable to the spray line of the spraying machine channel and connectable to the at least one nozzle port channel, so that the respective channels through the Control are connected to each other or separable, and that the control element is designed as a ball valve and actuated by means of a motor. The control lingers without supply of external energy in the control positions. The control element is preferably designed as a control valve. It is suggested that Form control as a ball valve, wherein the ball of the ball valve has at least one channel formed as a bore through which the channels formed in the nozzle device channels are connected to each other. For this purpose, the ball is brought into a corresponding control position, in which the openings of the channel formed in the ball are partially or completely covered with the openings of the channels formed in the Düsenvorrichtüng. The ball valve is preferably mounted in a ball valve seat formed by ball sockets, wherein the ball valve seat is disposed within the nozzle device between the channels to be connected. By frictional engagement between the ball wall of the ball valve and the wall of the ball seat a set control position of the ball valve is maintained without the need to apply external energy. The ball valve can also with multiple branched channels or with be provided with a plurality of holes whose openings can connect several channels or a selection of channels with each other. Thus, in the ball valve, for example, a T-shaped, star-shaped or also "three-legged" -shaped channel composite can be formed by which a plurality of channels can be connected or disconnected in different combinations with one another. The control element is preferably used to connect a nozzle attached to the nozzle device with the spray line of a spray boom or to interrupt the connection. It is conceivable to integrate several control elements in the nozzle device. The control can be brought by means of external energy or power-operated in different control positions or switched or adjusted. The Aufbriwgen the foreign energy to adjust the control takes place automatically in the form of electrical, magnetic, pneumatic or hydraulic energy. The control element is designed such that, as soon as it is brought into an adjustable control position, this set control position is maintained, without the control element or an adjusting means provided for adjusting the control element external energy in the form of electrical, magnetic, hydraulic or pneumatic energy is supplied. This can be done for example by frictional engagement between the control element and the nozzle device and / or by self-locking adjusting means with which the control element is adjustable. A self-locking adjusting means may be formed, for example, as a spindle connected to the control, which changes the position of the control by turning and self-locking the control in his standstill Holding position. The nozzle device may be formed with a plurality of channels, at least one of which is connected to the spray line of a syringe linkage. At least one further channel leads to a nozzle attached to the nozzle device, through which spraying liquid can be discharged. The nozzle device may also be provided with a plurality of nozzles, which may be the same or different. In this case, a plurality of channels leading to a nozzle or even multiple channels leading to different nozzles may be formed in the nozzle device. By using a plurality of nozzles of the same and / or different type, the spray quantity and / or the pointed jet shape can be varied and regulated. The control element is arranged between the channel connected to the spray line of the spraying machine and at least one channel connected to a nozzle, so that the respective channels can be connected to one another or separated from one another by the control element. Furthermore, it is conceivable to design the control in such a way that control positions are adjustable, in which different channels with a channel leading to a spray line or several channels leading to one or more nozzles are simultaneously connected to a channel leading to a spray line. The advantage here is that the nozzles connected to the nozzle device may have different outlet openings and different nozzles are automatically selected via the control. By appropriate design of the control and several of the respective channels can be connected at the same time with a channel connected to the spray line. Different switch combinations of the nozzles are conceivable with each other, so that, for example, the application rate is adjustable by adjusting the control by one or two or more nozzles simultaneously spray liquid. It is conceivable that the control positions occupied by the control also have control position in which the flow is reducible between two channels, such that in such a
Steuerstellung nur ein Teil des Flüssigkeitsstromes durchgelassen wird. Durch entsprechende Steuerstellungen zwischen einer geöffneten und einer geschlossenen Steuerstellung, die sowohl stufenlos als auch in Stufen einstellbar sein können, kann der Durchfluss von Spritzflüssigkeit und damit auch eine Ausbringmenge von Spritzflüssigkeit reguliert werden, ohne dass der Austrittsquerschnitt einer Düse geändert bzw. eine unterschiedliche Düse gewählt werden muss.Control position only a portion of the liquid flow is passed. By appropriate control positions between an open and a closed control position, which can be adjusted both infinitely and in stages, the flow of spray liquid and thus an application rate of spray can be regulated without the outlet cross section of a nozzle changed or selected a different nozzle must become.
Vorzugsweise ist das Steuerelement mittels eines Motors betätigbar. Dafür eignen sich besonders ansteuerbare Elektromotoren, die über eine Spindel mit dem Steuerelement verbunden sind. Der Elektromotor kann beispielsweise als impulsgesteuerter Schrittmotor ausgebildet sein. Denkbar sind aber auch andere Arten von Elektromotoren, die eine feinjustierte Verstellung des Steuerelements zulassen. Dabei können gegebenenfalls auch Untersetzungsgetriebe zum Einsatz kommen um eine Feinjustierung des Steuerelements durch eine Dreh- oder Linearbewegung zu realisieren.Preferably, the control is actuated by means of a motor. For this are particularly controllable electric motors, which are connected via a spindle with the control. The electric motor may be formed, for example, as a pulse-controlled stepper motor. Conceivable, however, are other types of electric motors that allow a finely adjusted adjustment of the control. If necessary, also reduction gear can be used to realize a fine adjustment of the control by a rotary or linear movement.

Derartige Spritzen, beispielsweise Anbauspritzen, Anhängespritzen oder auch selbstfahrende Spritzen, weisen ein Spritzengestänge auf, welches sich horizontal zur Fahrtrichtung der Spritze und zum Boden erstreckt. Das Spritzengestänge trägt eine Spritzleitung, welche sich entlang des Spritzengestänges erstreckt. Die Spritzleitung ist mit mehreren Düsenvorrichtungen bestückt, die entlang der Spritzleitung über die gesamte Breite des Spritzengestänges verteilt angeordnet sind. Die Spritzleitung kann als starres Rohr ausgebildet sein, welches mit mehreren Spritzleitungsbohrungen versehen ist, durch welche Spritzflüssigkeit in die Düsenvorrichtungen geleitet wird. Ein derartiges mit erfindungsgemäßen Düsenvorrichtungen versehenes Spritzengestänge bietet den Vorteil, neben den bereits genannten Vorteilen beim Einsatz einer erfindungsgemäßen Düsenvorrichtung, dass aufgrund der Ausbildung der Düsenvorrichtung, jede einzelne Düsenvorrichtung ansteuerbar ist und somit eine genauere Breiteneinstellung beim Ausbringen von Spritzflüssigkeit gegenüber einem teilbreitengesteuerten Spritzengestänge ermöglicht wird.A nozzle device according to the invention is particularly suitable for use on agricultural sprayers. Such syringes, for example Mounted sprayers, trailed sprayers or self-propelled sprayers, have a spray boom, which extends horizontally to the direction of travel of the syringe and to the ground. The syringe linkage carries a spray line which extends along the syringe linkage. The spray line is equipped with a plurality of nozzle devices, which are arranged distributed along the spray line over the entire width of the spray boom. The spray line may be formed as a rigid tube, which is provided with a plurality of spray line holes through which spray liquid is passed into the nozzle devices. Such a syringe linkage provided with nozzle devices according to the invention offers the advantage, in addition to the already mentioned advantages when using a nozzle device according to the invention, that due to the design of the nozzle device, each individual nozzle device is controllable and thus a more accurate width adjustment when dispensing spray liquid over a part width-controlled sprayer boom is made possible.
