Abstract

A device for preventive combating of voles is characterised in that the housing is formed by an elongate tube which is open on both sides and the upper cover of which consists of a closure lid sealed in a gastight manner, and in that the device has a stamp, which can be inserted into the tube, for driving in the tube, the length of which is greater than or equal to that of the tube.

Description

In der Figur ist mit 1 das ins Erdreich einzubringende Rohr, mit 2 der Schlagstempel und mit 3 der Verschlußdeckel der Vorrichtung bezeichnet. Zum Eintreiben des Rohres 1 in das Erdreich wird der Schlagstempel 2 in das Rohr 1 eingesteckt, wonach das Rohr so weit in das Erdreich eingeschlagen wird, bis dessen oberes Ende im wesentlichen mit der Bodenoberfläche bündig ist. Danach wird ein schüttfähiges Vergräinungsrnittel, das mit 4 bezeichnet ist, iii das unten offene Rohr 1 eingefüllt und schließlich oben der Verschlußdeckel 3 auf das Rohr 2 aufgesetzt. Die schließlich im Laufe der Zeit durch das Carbid freigesetzten Gase treten am unteren Rohrende in das benachbarte Erdreich über, wo sie infolge der Geruchsentfaltung Wühlmäuse aus der Einschlagzonedes Rohres 1 vertreiben. In the figure, 1 is the pipe to be inserted into the ground, with 2 denotes the punch and 3 denotes the cap of the device. To the Driving the pipe 1 into the ground, the punch 2 is inserted into the pipe 1, after which the pipe is knocked into the ground until its upper end is substantially flush with the ground surface. Then a pourable Vergräinungsrnittel, which is denoted by 4, iii the tube 1, which is open at the bottom, is filled and Finally, the cap 3 is placed on the tube 2 at the top. The finally Gases released over time by the carbide occur at the bottom of the tube into the neighboring soil, where they voles as a result of the odor development from the impact zone of the pipe 1.

Als schüttfähiges Vergrämungsmittel kann jedes Mittel, vorzugsweise in Pulver- oder Granulatform, verwendet werden, sofern es für die beabsichtigten Zwecke geeignet ist. Bevorzugt wird jedoch Carbid verwendet. Any agent, preferably in powder or granular form, if it is intended for use Purposes. However, preference is given to using carbide.

Der Schlagstempel 2 besitzt an seinem oberen Ende einen seitlich vom Stempelschaft 5 abkragenden Bund 6, der in Einschlagstellung des Rohres 1 an der oberen Rohrstirnfläche anliegt, die mit 7 bezeichnet ist. Die ab dem Bund 6 gemessene Länge des Stempelschafts 5 ist mindestens gleich groß wie die des Rohres 1, so daß sichergestellt ist, daß beim Eintreiben des Rohres 1 in das Erdreich das Rohrinnere nicht mit Erdreich gefüllt und damit verstopft wird. Vorzugsweise ist jedoch der Stempelschaft 5 länger als das Rohr 1, so daß in der Figur rechts dargestellten Gebrauchsstellung der Vorrichtung unterhalb des Rohres 1 ein das Übertreten der freisetzenden Vergrämungsgase erleichternder Hohlraum 8 im Erdreich gebildet ist. Wie aus der Figur deutlich entnehmbar ist, ist der Stempelschaft 5 an seinem unteren Ende zur Erleichterung des Eintreibens zugespitzt. The punch 2 has a side at its upper end from the punch shaft 5 cantilevered collar 6, which is in the driving position of the tube 1 the upper pipe end face, which is denoted by 7, rests. The federal government 6 measured length of the punch shaft 5 is at least the same as that of the tube 1, so that it is ensured that when the pipe 1 is driven into the ground The inside of the pipe is not filled with soil and thus clogged. Preferably is however, the punch shaft 5 is longer than the tube 1, so that shown on the right in the figure Position of use of the device below the tube 1 a crossing of the releasing deterrent gases facilitating cavity 8 is formed in the ground. As can be clearly seen from the figure, the punch shaft 5 is at its lower one Pointed end to facilitate driving.

Der Verschlußdeckel 3 kann durch Bajonett- oder Schraubverschluß auf dem Rohr befestigt sein. Nach der Darstellung in der Figur ist der Verschlußdeckel 3 jedoch lediglich auf das obere Rohrende aufgesteckt, wobei ein mit 9 bezeichneter Rohrfortsatz in das obere Rohrende eingreift. Innerhalb des Rohrfortsatzes 9 ist ein mit 10 bezeichneter Filz aufgenommen, der mit einem geeigneten Vergrämungsmittel mit Langzeitwirkung versehen ist. Der Filz 10 kann durch Kleben oder in sonst geeigneter Weise im Verschlußdeckel 3 aufgenommen scin. Zweckmäßigerweise ist er jedoch in den Rohrfortsatz 9 eingequetscht, was dadurch erfolgt, daß der Filz 10 mit einer gegenüber dem Rohrfortsatz größeren Querschnitt ausgebildet ist. Langzeitwirkung bedeutet, daß das Vergrämungsmittel mit einem Stoff versetzt ist, welches nur ein allmähliches Freisetzen der Gase ermöglicht, so daß das Vergrämungsmittel nicht schnell, sondern nur langsam aufgebraucht wird. Als Vergrämungsmittel eignen sich hierbei insbesondere stark geruchsbelastende ölige Medien, wie etwa Steinteer u. dgl. Ein gasdichter Abschluß erfolgt durch einen O-Ring 11. The cap 3 can be bayonet or screw lock be attached to the pipe. As shown in the figure, the closure cap 3, however, only pushed onto the upper end of the pipe, with a designated 9 Pipe extension engages in the upper end of the pipe. Inside the tubular extension 9 is a felt designated by 10 was added, which was treated with a suitable deterrent is provided with long-term effects. The felt 10 can be glued or otherwise suitable Way in the cap 3 scin added. Appropriately, however, it is in the tubular extension 9 squeezed, which takes place in that the felt 10 with a compared to the tubular extension is formed larger cross-section. Long-term effect means that the deterrent has been mixed with a substance which is only one allows gradual release of the gases so that the deterrent does not is used up quickly but slowly. As a deterrent are suitable in particular, oily media with a strong odor, such as rock tar and the like. The like. A gas-tight seal is provided by an O-ring 11.

Damit der Verschlußdeckel 3 dem beim Umsetzen des Carbids in Kalk entstehenden Dampfdruck standhalten kann, sitzt der Verschlußdeckel 3 mit Paßsitz, also vergleichsweise fest auf dem Rohr auf. So that the cap 3 when converting the carbide in lime can withstand the resulting vapor pressure, the cap 3 sits with a snug fit, so comparatively firmly on the pipe.

Im Falle eines nicht absprengbaren Verschlusses, etwa Bajonett- oder Schraubverschlusses, aber auch bei jeder anderen Verschlußart kann zur weiteren Sicherung eine Druckentlastungsöffnung im Verschlußdeckel 3 vorgesehen sein, diese ist in der Figur nur schematisch mit 12 bezeichnet. Dabei ist allerdings die Entlastungsöffnung so ausgelegt, daß nur dann ein Entweichen des Gases stattfindet, wenn ein so hoher Druck aufgebaut wird, daß es zu einem Absprengen des Verschlußdeckels 3 kommt. In the case of a non-detachable lock, such as a bayonet or Screw cap, but also with any other type of closure can be used to further Securing a pressure relief opening in the cap 3 be provided, this is only indicated schematically in the figure with 12. Here, however, is the relief opening designed in such a way that the gas only escapes if such a high one Pressure is built up that the closure cover 3 bursts off.

Wie der Figur ferner zu entnehmen ist, können zusätzlich am unteren Rohrende Gasdurchtrittsöffnungen 13 im Rohrmantel vorgesehen sein. As the figure can also be seen, can also be at the bottom Pipe end gas passage openings 13 may be provided in the pipe jacket.

Das Rohr 2 kann aus Metall hergestellt sein, aber auch aus Kunststoff, so daß bei einem evtl. Herauswaschen des oberen Rohrendes ein Überfahren mit einem Rasenmäher für diesen unschädlich ist. The tube 2 can be made of metal, but also of plastic, so that if the upper end of the pipe is washed out, it will be run over with a Lawnmower is harmless for this.

6. Device according to one of the preceding claims, characterized in that that the cap (3) is secured by a pressure relief opening (12).

The invention relates to a device according to the preamble of Claim 1.

A so-called vole cone is known for combating voles DE-PS 27 35 513, which has a conical, open-bottom protective housing, in which Inside, on a grate, a felt filled with detergent secured against water is recorded. This vole cone has proven itself in practice in combating Tried and tested by voles. However, there are several ways in which it can be improved. Although the vole cone is filled with a deterrent with long-term effects, which, however, is used up after a certain time. Should then a refill process take place, it is practically impossible to find the vole cone again. Even if the place where the vole cone is brought into the ground, through If a stake is marked, this would mean the excavation of the vole cone Damage the roots of a tree, for example, which the vole cone protects is buried in the root area mostly when the tree is planted. Furthermore it is required to bring in the vole cone soil to form a pit to dig after which the vole cone is inserted into the pit and then the soil is poured up again, which is comparatively expensive. It is also difficult in the case of a tree or bush that has already been planted, add the vole cone afterwards in a suitable place below the root ball, where it has its larger one Can develop an effect without damaging the roots and thus the plant itself.

Finally, a device for driving away voles is known (DE-OS 31 40 658), in which in a housing covered at the top, which is open at the bottom, a bowl-shaped boat is added, which means a deterrent records.

This device must also be placed in the ground as a whole, so that it can no longer be easily found afterwards, and this The device thus suffers from the same disadvantages as the one described above Vole cone.

The object of the invention is to provide a device of the type outlined at the outset Further develop the genus in such a way that it can be used easily and without damage to the roots can be brought into the position of use and a simple refilling at any time made possible with a deterrent.

This object is achieved according to the invention by the in the characterizing part of the features contained in claim l solved.

According to the invention, the device comprises preventive Fighting voles an elongated pipe, open on both sides, which can be closed gas-tight with a cap and a punch for Insertion of the pipe into the ground. The punch prevents the impact of the pipe a penetration of soil into the pipe interior, which after introduction in the ground filled with a deterrent in pourable form and then through Placing the cap is closed. The deterrent sets odorous Free gases that pass into the neighboring soil at the lower open end of the pipe can. All that is needed to refill the deterrent is the cap to be removed without the pipe being removed from the ground.

Although it is known (US-PS 25 39 271), an insertable into a pipe Use punches to drive the pipe into the ground. This pipe but only serves to create a passage from above to a vault exit, to throw toxins or the like through the pipe into the vaulting outlet.

A preventive protection of plants against damage by voles however, this is not possible.

Appropriate further developments of the invention are indicated in the subclaims features included.

An exemplary embodiment of the invention is described below with reference to FIG Description of the drawing showing a single figure with the device in the insertion position shows in the ground and in the position of use.
