Description

Es ist bekannt, tierische Schädlinge, wie Vögel, Wild oder auch Kartoffelkäfer, im freien Gelände mit Ultraschall zu bekämpfen. Man verwendet zu diesem Zweck Ultraschallfrequenzen, die oberhalb, des menschlichen Hörbereiches, aber innerhalb des auf das als Schädling in Betracht kommenden Tieres abschreckend wirkenden Bereiches liegen. Bei der Verwendung dieses Verfahrens ist festgestellt worden, daß sich die Schädlinge verhältnismäßig schnell an die aufgestellte Frequenz gewöhnen, und es ist deshalb vorgeschlagen worden, die betreffenden Ultraschallgeräte mit einer periodisch wechselnden Frequenz oder/und Intensität zu betreiben. Zu diesem Zweck -wird also entwederIt is known to pest animals, such as birds, game or Colorado beetles, in open terrain to fight with ultrasound. For this purpose, ultrasonic frequencies are used which are above, of the human hearing range, but within that which is considered to be a pest Animal's deterrent area. When using this procedure it is found that the pests get used to the established frequency relatively quickly, and it has therefore been proposed that the ultrasonic devices concerned be periodically alternating frequency and / or intensity to operate. To this end - so either will

is der Schwingungsgeber in seiner Eigenfrequenz gewobbelt oder aber die Intensität der abgestrahlten Schwingungen periodisch geändert. Das Wobbein der Frequenz erfordert elektrische Schaltmittel im Generator und das periodische Schwächen der Intensität solche Mittel in der Energiezuführungsleitung (z. B. Druckluftleitung zu einer Sirene).is the vibration generator wobbled in its natural frequency or the intensity of the emitted vibrations changed periodically. The wobble the frequency requires electrical switching means in the generator and the periodic weakening of the intensity such means in the energy supply line (e.g. compressed air line to a siren).

Erfindungsgemäß kann eine wirksame Schädlingsbekämpfung im freien Gelände mit einfachen Mitteln in der Weise durchgeführt werden, daß das mit Ultraschallwellen zu bestrahlende Flächenstück mittels eines rotierenden Ultraschallgebers absatzweise wiederholt bestrahlt wird. Durch das Rotieren eines Ultraschallgebers, der vorzugsweise in der Mitte des zu bestrahlenden Geländeabschnittes aufgestellt ist, werden jegliche zusätzliche Schaltmittel zur Änderung der Frequenz bzw. der Intensität vermieden, obwohl jeder einzelne Geländeabschnitt mit stark wechselnder Intensität — bei guten Schallreflektoren sinkt die Intensität bis zum Wert Null — bestrahlt wird. Hierdurch wird die beabsichtigte physiologische Wirkung- auf den einzelnen Schädling erzielt.According to the invention, effective pest control in open terrain can be achieved with simple Means are carried out in such a way that the surface piece to be irradiated with ultrasonic waves is irradiated repeatedly intermittently by means of a rotating ultrasonic transducer. By the Rotation of an ultrasound transducer, which is preferably in the middle of the section of the terrain to be irradiated is set up, any additional switching means for changing the frequency or of intensity, although each individual section of the terrain varies greatly in intensity - with good sound reflectors, the intensity drops down to the value zero - irradiation takes place. Through this the intended physiological effect is achieved on the individual pest.

In der Zeichnung ist eine Beschallungseinrichtung dargestellt, wie sie zur Durchführung des Verfahrens nach der Erfindung im Mittelpunkt • eines zu bestrahlenden Geländeabschnittes aufgestellt werden kann.In the drawing, a sound system is shown as it is used to carry out the Method according to the invention in the center • of a terrain section to be irradiated can be.

Der Rundstrahler 4 besteht aus vier einzelnen Schallgebern, die jeder für sich in einem Reflektor 4' angeordnet sind. Die Rundstrahler sind drehbar in der Mitte-des von Ungeziefer freizuhaltenden Geländeabschnittes aufgestellt. Die vier Schallgeber können mit unterschiedlichen Frequenzen betrieben werden, so daß bei Drehung des Rundstrahlers jeder einzelne Teil des Geländeabschnittes mit vier verschiedenen Frequenzen an- und abschwellender Intensität bestrahlt wird. Als Ultraschallgeber werden Sirenen verwendet, die auf Grund ihrer mit geringem Aufwand zu erzielenden großen Leistung zur Schädlingsbekämpfung besonders geeignet sind.The omnidirectional radiator 4 consists of four individual sounders, each of which is in a reflector 4 'are arranged. The omnidirectional radiators can be rotated in the middle of the area to be kept free from vermin Terrain section set up. The four sounders can be operated at different frequencies so that when the omnidirectional radiator is rotated, every single part of the terrain section is irradiated with four different frequencies of increasing and decreasing intensity. As an ultrasonic transmitter sirens are used, which can be achieved with little effort due to their great performance for pest control are particularly suitable.

Die zum Betrieb der Ultraschallsirene vorhandene Druckluft kann gleichzeitig zum Antrieb des Rundstrahlers Verwendung finden, wobei die Rückstrahlkraft der aus -jeder einzelnen Sirene austretenden Druckluft ausgenutzt werden kann.The compressed air available to operate the ultrasonic siren can also be used to drive the Omnidirectional radiators are used, with the reflective power emitted from each individual siren Compressed air can be used.
