Description

Die Erfindung betrifft eine Streuvorrichtung zum Ausstreuen von Streugut, insbesondere Sand oder Bodensubstraten, auf einer Bodenoberfläche, insbesondere auf Golfplätzen nach dem Oberbegriff des Anspruchs 1.The invention relates to a scattering device for scattering grit, in particular sand or soil substrates, on a soil surface, in particular on golf courses according to the preamble of claim 1.

Bisher bekannte Streuvorrichtungen zum Ausstreuen von Streugut, insbesondere auf Golfplätzen weisen einen Behälter für das Streugut und mindestens eine Streueinheit auf, mittels der das in dem Behälter befindliche Streugut ausstreubar ist. Die Streueinheit weist meistens eine im Wesentlichen bodenparallele, drehbare Streuscheibe auf. Ferner ist meistens mindestens eine Antriebseinrichtung zum Drehen der Streuscheibe um die Drehachse vorgesehen. Das Streugut kann aufgrund des Drehens der Streuscheibe mittels der Streuscheibe und aufgrund von Fliehkräften ausstreubar sein.Hitherto known spreading devices for spreading grit, in particular on golf courses, have a container for the grit and at least one spreading unit, by means of which the grit in the container can be spread. The spreading unit mostly has a rotatable spreading disc that is essentially parallel to the ground. Furthermore, at least one drive device is usually provided for rotating the diffusion disk about the axis of rotation. The spreading material can be spreadable due to the rotation of the spreading disc by means of the spreading disc and due to centrifugal forces.

Derartige Streuvorrichtungen sind aus der EP 0 104 622 A2 , DE 27 30 256 A1 und der AT 009 137 U2 , US 2013/341437 A1 sowie US 2002/117562 A1 bekannt.Such spreading devices are from EP 0 104 622 A2 , DE 27 30 256 A1 and the AT 009 137 U2 , US 2013/341437 A1 such as US 2002/117562 A1 known.

Solche Streuvorrichtungen werden häufig auf Golf- oder Rasenplätzen verwendet. Dabei besteht das Problem, dass bei manchen Rasenflächen das Streugut nur in eine bestimmte Richtung gestreut werden soll. Auch besteht häufig die Aufgabe bei Golfplätzen mit einer solchen Vorrichtung, zum Beispiel Bunker zu befüllen, ohne den darum liegenden Rasen zu bestreuen.Such spreaders are often used on golf or grass courses. The problem here is that on some lawns the grit should only be spread in a certain direction. There is also often the task at golf courses with such a device, for example to fill bunkers, without sprinkling the lawn around them.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Streuvorrichtung zu schaffen, die in einem definierten Bereich streuen kann.The invention is therefore based on the object of creating a spreading device which can spread over a defined area.

Zur Lösung dieser Aufgabe dienen die Merkmale des Anspruchs 1.The features of claim 1 serve to solve this problem.

Die Erfindung sieht vor, dass eine Begrenzungseinrichtung in zumindest einem Teil des Umfangsbereiches der Streuscheibe angeordnet ist, die das Ausstreuen des Streuguts in diesen Teil des Umfangsbereichs verhindert, wobei die Position der Begrenzungseinrichtung relativ zu der Streuschreibe verstellbar ist, so dass die Richtung in der das Streugut ausstreubar ist, veränderbar ist.The invention provides that a limiting device is arranged in at least a part of the circumferential area of the spreading disc, which prevents the scattering of the grit in this part of the peripheral area, the position of the limiting device being adjustable relative to the spreading disc, so that the direction in which the Grit can be spread, is changeable.

Auf diese Weise kann das Streugut in eine definierte Richtung ausgestreut werden.In this way, the grit can be spread in a defined direction.

Es können somit Bunker auf einen Golfplatz befüllt werden, ohne dass das umliegende Gras mit dem Streugut bestreut wird. Auch können bestimmte Bereiche der Bodenfläche lediglich mit dem Streugut bestreut werden.Bunkers on a golf course can therefore be filled without the surrounding grass being sprinkled with the grit. Also, certain areas of the floor can only be sprinkled with the grit.

Die Streuscheibe ist dabei um eine Drehachse drehbar, wobei die Begrenzungseinrichtung um die Schwenkachse verschwenkbar ist, so dass die gesamte Begrenzungseinrichtung in unterschiedlichen Umfangsbereichen der Streuscheibe platzierbar ist.The diffuser is rotatable about an axis of rotation, the delimitation device being pivotable about the pivot axis, so that the entire delimitation device can be placed in different circumferential regions of the diffuser.

Beim Verstellen der Begrenzungseinrichtung bleibt daher die Streubreite, mit der das Streugut ausstreubar ist, konstant. Es wird somit lediglich die Richtung in der das Streugut ausgestreut wird, verändert und nicht die Streubreite. Die Streubreite wird die Breite auf der Bodenfläche verstanden, auf der das Streugut beim einmaligen Überfahren mit der Streuvorrichtung ausgestreut wird.When adjusting the limiting device, the spread width with which the spreading material can be spread remains constant. It only changes the direction in which the grit is spread and not the spreading width. The spreading width is understood to be the width on the floor area on which the spreading material is spread when the spreading device is passed over it once.

Es kann ein Linearmotor mit der Begrenzungseinrichtung und einem Gehäuseelement der Streueinheit verbunden sein und die Begrenzungseinrichtung verstellen. Der Linearmotor kann elektrisch, hydraulisch oder pneumatisch betrieben sein.A linear motor can be connected to the limiting device and a housing element of the spreading unit and can adjust the limiting device. The linear motor can be operated electrically, hydraulically or pneumatically.

Die Antriebseinrichtung zum Drehen der Streuscheibe kann ebenfalls eine elektrische, hydraulische oder pneumatische Antriebseinrichtung sein.The drive device for rotating the spreading disc can also be an electrical, hydraulic or pneumatic drive device.

Es kann mindestens ein Schaufelelement im Wesentlichen radial auf der Streuscheibe angeordnet sein.At least one vane element can be arranged essentially radially on the diffuser.

Die Begrenzungseinrichtung kann in einer Richtung, die parallel zu der Drehachse verläuft, höher sein als die auf der Streuscheibe angeordneten Schaufelelemente. Auf diese Weise ist sichergestellt, dass das Streugut nicht über die Begrenzungseinrichtung unbeabsichtigt gestreut wird.The limiting device can be higher in a direction which runs parallel to the axis of rotation than the vane elements arranged on the diffuser. In this way it is ensured that the spreading material is not unintentionally spread over the limiting device.

Die Begrenzungseinrichtung ist erfindungsgemäß ein Blechelement.According to the invention, the limiting device is a sheet metal element.

Die als Blechelement ausgebildete Begrenzungseinrichtung weist am oberen und unteren freien Ende eine in Richtung der Streuscheibe hervorstehende Blechkante auf, wobei die untere hervorstehende Blechkante unterhalb der Streuscheibe angeordnet ist. Die Begrenzungseinrichtung kann gebogen ausgebildet sein und an die Form des Außenumfangs der Streuscheibe angepasst sein.The delimitation device designed as a sheet metal element has at the upper and lower free end a sheet metal edge protruding in the direction of the diffuser, the lower protruding sheet metal edge being arranged below the diffuser. The delimitation device can be curved and adapted to the shape of the outer circumference of the diffuser.

Die Begrenzungseinrichtung ist weiterhin in einem definierten Abstand zu der Streuscheibe angeordnet sein, wobei der Abstand von der Begrenzungseinrichtung zu der Streuscheibe erfindungsgemäß weniger als 1 cm, insbesondere weniger als 0,5 cm, beträgt. Die Streuvorrichtung ist selbstfahrend oder mittels eines Zugfahrzeugs ziehbar.The delimitation device is furthermore arranged at a defined distance from the lens, the distance from the delimitation device to the lens according to the invention being less than 1 cm, in particular less than 0.5 cm. The spreading device is self-propelled or can be pulled by means of a towing vehicle.

Es kann eine Steuereinrichtung vorgesehen sein, die die Verstellung der Begrenzungseinrichtung und damit die Richtung, in der das Streugut ausstreubar ist, steuert.A control device can be provided which controls the adjustment of the limiting device and thus the direction in which the spreading material can be spread.

Die Steuereinrichtung kann die Verstellung der Begrenzungseinrichtung abhängig von der Transportrichtung der Streuvorrichtung steuern.The control device can control the adjustment of the limiting device as a function of the transport direction of the spreading device.

Die Steuereinrichtung kann die Verstellung der Begrenzungseinrichtung abhängig von der Lenkrichtung der selbstfahrenden Streuvorrichtung oder des Zugfahrzeugs steuern.The control device can control the adjustment of the limiting device as a function of the steering direction of the self-propelled spreading device or the towing vehicle.

Die Streuvorrichtung kann nur eine einzelne Streuscheibe aufweisen.The spreading device can only have a single spreading disc.

Es kann eine Nachfülleinrichtung vorgesehen sein, mittels der das Streugut von dem Behälter auf die Streuscheibe überführbar ist, wobei die Menge des Streuguts pro Zeit vorzugsweise mittels der Nachfülleinrichtung dosierbar ist.A refilling device can be provided, by means of which the spreading material can be transferred from the container to the spreading disc, the amount of spreading material per time preferably being metered by means of the refilling device.

Im Folgenden wird unter Bezugnahme auf die Zeichnungen Ausführungsbeispiele der Erfindung näher erläutert.In the following, exemplary embodiments of the invention are explained in more detail with reference to the drawings.

Fig. 1 zeigt eine Streuvorrichtung 1 zum Ausstreuen von Streugut. In Fig. 1 ist eine Streuvorrichtung 1 dargestellt, die von einem Zugfahrzeug gezogen werden kann. Die Streuvorrichtung 1 weist eine Ankoppeleinrichtung 32 zum Ankoppeln an ein Zugfahrzeug auf. Alternativ kann die Streuvorrichtung auch selbstfahrend sein. Fig. 1 shows a spreading device 1 for spreading spreading material. In Fig. 1 a spreading device 1 is shown, which can be pulled by a towing vehicle. The spreading device 1 has a coupling device 32 for coupling to a towing vehicle. Alternatively, the spreading device can also be self-propelled.

Die Streuvorrichtung 1 weist einen Behälter 6 für das Streugut und mindestens eine Streueinheit 4 auf, mittels der das in dem Behälter 6 befindliche Streugut ausstreubar ist. Es ist vorzugsweise eine Nachfülleinrichtung 8 vorgesehen, mittels der das Streugut von dem Behälter 6 zu der Streueinheit 4 überführbar ist.The spreading device 1 has a container 6 for the spreading material and at least one spreading unit 4, by means of which the spreading material located in the container 6 can be spread out. A refilling device 8 is preferably provided, by means of which the spreading material can be transferred from the container 6 to the spreading unit 4.

Die Streuvorrichtung 1 weist vorzugsweise mehr als zwei Räder 34 auf, mittels der die Streuvorrichtung 1 über die Bodenfläche 2 fahrbar ist. Bei mehr als zwei Rädern 34 ist das Gewicht, dass die mit Streugut beladene Streuvorrichtung 1 auf die Bodenfläche 2 ausübt, besser verteilt. Im vorliegenden Fall weist die Streuvorrichtung 1 vier Räder 34 auf. Ferner weist die Streuvorrichtung 1 ein Transportrad 36 auf, das jedoch in einem Zustand, in dem die Streuvorrichtung mit einem Zugfahrzeug verbunden ist, eingezogen ist und nicht in Kontakt mit der Bodenfläche 2 ist.The spreading device 1 preferably has more than two wheels 34, by means of which the spreading device 1 can be moved over the floor surface 2. If there are more than two wheels 34, the weight that the spreading device 1 loaded with spreading material exerts on the floor surface 2 is better distributed. In the present case, the spreading device 1 has four wheels 34. Furthermore, the spreading device 1 has a transport wheel 36, but in a state in which the spreading device is connected to a towing vehicle, is drawn in and is not in contact with the floor surface 2.

Die Streueinheit 4 ist in den Fign. 2 bis 4 näher dargestellt. Die Streueinheit 4 weist eine im Wesentlichen bodenparallele, drehbare Streuscheibe 12 auf, die, vorzugsweise um eine zu der Bodenfläche 2 im Wesentlichen orthogonal verlaufenden Drehachse 24 drehbar ist. Die Drehachse 24 kann, wie im vorliegenden Fall, eine rein imaginäre Achse und kein Bauteil sein. Auf der Streuscheibe 12 ist mindestens ein Schaufelelement 14 im Wesentlichen radial angeordnet. Es können mehrere Schaufelelemente 14 auf der Streuscheibe 12 angeordnet.The spreading unit 4 is in the Figs. 2 to 4 shown in more detail. The spreading unit 4 has a rotatable spreading disc 12 which is essentially parallel to the floor and which is rotatable, preferably about an axis of rotation 24 which runs essentially orthogonally to the floor surface 2. As in the present case, the axis of rotation 24 can be a purely imaginary axis and not a component. At least one vane element 14 is arranged essentially radially on the diffusing screen 12. A plurality of vane elements 14 can be arranged on the diffusion disk 12.

Es ist mindestens eine Antriebseinrichtung 20 zum Drehen der Streuscheibe 12 um die Drehachse 24 vorgesehen, so dass das Streugut mittels der Streuscheibe 12 und aufgrund von Zentrifugalkräften ausstreubar ist. Die Antriebseinrichtung 20 weist eine Welle 18 auf, die mit der Streuscheibe 12 verbunden ist und die Streuscheibe antreibt. Die Antriebseinrichtung 20 ist in einem Gehäuseelement 22 gelagert. An dem Gehäuseelement 22 ist ferner eine Abschirmeinrichtung 10 angeordnet, die verhindert, dass das Streugut nach oben ausgeworfen werden kann.At least one drive device 20 is provided for rotating the spreading disc 12 about the axis of rotation 24 so that the spreading material can be spread out by means of the spreading disc 12 and due to centrifugal forces. The drive device 20 has a shaft 18 which is connected to the lens 12 and drives the lens. The drive device 20 is mounted in a housing element 22. A shielding device 10, which prevents the spreading material from being ejected upward, is also arranged on the housing element 22.

Durch Drehen der Streuscheibe 12 mittels der Antriebseinrichtung 20 kann das Streugut ausgestreut werden. Dabei bewegt sich das Streugut aufgrund der Zentrifugalkraft in den Außenbereich der Streuscheibe 12 und wird von dort ausgeschleudert.By rotating the spreading disc 12 by means of the drive device 20, the spreading material can be spread out. Due to the centrifugal force, the spreading material moves into the outer area of the spreading disc 12 and is ejected from there.

Die Streueinheit 4 weist ferner eine Begrenzungseinrichtung 16 auf, die in zumindest einem Teil des Umfangsbereichs der Streuscheibe 12 angeordnet ist und das Ausstreuen des Streuguts in diesem Teil des Umfangsbereichs begrenzt. Das Streugut kann somit lediglich in der Richtung ausgestreut werden, die nicht mit der Begrenzungseinrichtung begrenzt ist.The spreading unit 4 also has a delimitation device 16 which is arranged in at least a part of the circumferential area of the spreading disc 12 and which limits the spreading of the grit in this part of the circumferential area. The spreading material can thus only be spread in the direction that is not limited by the limiting device.

Die Position der Begrenzungseinrichtung 16 ist relativ zu der Streuscheibe 12 verstellbar, so dass die Richtung in der das Streugut ausstreubar ist, veränderbar ist. Dass die Position der Begrenzungseinrichtung 16 relativ zu der Streuscheibe 12 verstellbar ist, bedeutet, dass die Begrenzungseinrichtung 16 in unterschiedlichen Umfangsbereichen der Streuscheibe plazierbar ist. Die Begrenzungseinrichtung 16 wird dabei vorzugsweise um die Drehachse 24 verschwenkt, so dass die Begrenzungseinrichtung 16 in unterschiedlichen Umfangsbereichen der Streuscheibe plazierbar ist.The position of the limiting device 16 can be adjusted relative to the diffusion disk 12, so that the direction in which the material to be spread can be changed. The fact that the position of the limiting device 16 is adjustable relative to the lens 12 means that the limiting device 16 can be adjusted in different Peripheral areas of the lens can be placed. The limiting device 16 is preferably pivoted about the axis of rotation 24, so that the limiting device 16 can be placed in different circumferential areas of the diffuser.

Durch Verstellen der Position der Begrenzungseinrichtung kann die Richtung, in der das Streugut ausgestreut wird, verstellt werden. Auf einem Golfplatz kann die Streuvorrichtung 1 somit als Auffüllvorrichtung für einen Bunker verwendet werden, ohne dass das umliegende Gras des Bunkers mit Streugut bestreut wird. Alternativ können Rasenflächen entlang eines Weges bestreut werden, ohne dass der Weg mit Streugut bedeckt wird.By adjusting the position of the limiting device, the direction in which the grit is spread can be adjusted. On a golf course, the spreading device 1 can thus be used as a filling device for a bunker without the grass surrounding the bunker being sprinkled with grit. Alternatively, lawns can be sprinkled along a path without the path being covered with grit.

Aus den Fign. 3 und 4 kann entnommen werden, wie die Begrenzungseinrichtung 16 verstellt werden kann. In den Fign. 3 und 4 ist die Streueinheit 4 von unten dargestellt.From the Figs. 3 and 4 it can be seen how the limiting device 16 can be adjusted. In the Figs. 3 and 4 the spreading unit 4 is shown from below.

Die Begrenzungseinrichtung 16 ist, wie in dem dargestellten Ausführungsbeispiel, ein Blechelement. Die als Blechelement ausgebildete Begrenzungseinrichtung 16 weist am oberen und unteren freien Ende eine in Richtung der Streuscheibe hervorstehende Blechkante 38, 40 auf, wobei die untere vorstehende Blechkante 40 unterhalb der Streuscheibe 12 angeordnet ist. Auf diese Weise wird verhindert, dass das Streugut unbeabsichtigt nach oben oder unten rausgeworfen wird.As in the illustrated embodiment, the limiting device 16 is a sheet metal element. The delimiting device 16, which is designed as a sheet metal element, has a sheet metal edge 38, 40 protruding in the direction of the lens at the upper and lower free end, the lower projecting sheet metal edge 40 being arranged below the lens 12. This prevents the grit from being accidentally thrown up or down.

Die Begrenzungseinrichtung 16 kann, wie im dargestellten Ausführungsbeispiel, gebogen ausgebildet sein und an die Form der Außenkante der Streuscheibe 12 angepasst sein. Die Begrenzungseinrichtung 16 ist mit definiertem Abstand zu der Streuscheibe 12 angeordnet sein, wobei der Abstand von der Begrenzungseinrichtung 16 zu der Streuscheibe 12 weniger als 1 cm, insbesondere weniger als 0,5 cm, beträgt. Auf diese Weise kann die Streuscheibe 12 ungehindert gedreht werden und trotzdem verhindert werden, dass zu viel Streugut zwischen der Begrenzungseinrichtung 16 und Streuscheibe 12 durchfällt und auf die Bodenfläche 2 fällt.The delimitation device 16 can, as in the exemplary embodiment shown, be of curved design and be adapted to the shape of the outer edge of the diffusion disk 12. The delimitation device 16 is arranged at a defined distance from the diffusion disk 12, the distance from the delimitation device 16 to the diffusion disk 12 being less than 1 cm, in particular less than 0.5 cm. In this way, the diffusion disk 12 can be rotated unhindered and nevertheless it is prevented that too much grit falls through between the limiting device 16 and the diffusion disk 12 and falls onto the floor surface 2.

In Fign. 3 und 4 ist eine Verstelleinrichtung 27 dargestellt, mittels der die Begrenzungseinrichtung 16 verstellbar ist. Die Verstelleinrichtung 27 kann, wie im dargestellten Ausführungsbeispiel, ein Linearmotor 26 sein. Der Linearmotor 26 ist an dem ersten Ende 26a mit dem Gehäuseelement 22 der Streueinheit 4 verbunden und an dem zweiten Ende 26b mit der Begrenzungseinrichtung 16 verbunden. Durch Verstellen des Linearmotors 26 kann die Position der Begrenzungseinrichtung 16 relativ zu der Streuscheibe 12 verstellt werden.In Figs. 3 and 4 an adjusting device 27 is shown, by means of which the limiting device 16 can be adjusted. The adjusting device 27 can, as in the illustrated embodiment, be a linear motor 26. The linear motor 26 is connected at the first end 26a to the housing element 22 of the scattering unit 4 and is connected to the limiting device 16 at the second end 26b. By adjusting the linear motor 26, the position of the limiting device 16 can be adjusted relative to the diffusion disk 12.

In Fig. 4 ist ein Zustand dargestellt, bei dem der Linearmotor 26 eingefahren ist und die Begrenzungseinrichtung 16 in Vergleich zu Fig. 3 verstellt ist.In Fig. 4 a state is shown in which the linear motor 26 is retracted and the limiting device 16 in comparison to FIG Fig. 3 is adjusted.

Es kann eine Steuereinrichtung 30 vorgesehen sein, die die Verstellung der Begrenzungseinrichtung 16 und damit die Richtung in der das Streugut abwerfbar ist, steuert. Die Steuereinrichtung 30 kann die Verstellung der Begrenzungseinrichtung 16 abhängig von der Transportrichtung der Streuvorrichtung steuern. Die Steuereinrichtung 30 kann die Verstellung der Begrenzungseinrichtung 16 abhängig von der Lenkeinrichtung des Zugfahrzeugs steuern. Auch kann eine Person, die das Zugfahrzeug bedient, die Steuereinrichtung 30 bedienen und die Begrenzungseinrichtung 16 somit steuern.A control device 30 can be provided which controls the adjustment of the limiting device 16 and thus the direction in which the spreading material can be thrown off. The control device 30 can control the adjustment of the limiting device 16 depending on the transport direction of the spreading device. The control device 30 can control the adjustment of the limiting device 16 as a function of the steering device of the towing vehicle. A person who operates the towing vehicle can also operate the control device 30 and thus control the limiting device 16.

Vorzugsweise weist die Streueinheit 4 nur eine einzelne Streuscheibe 12 auf.The scattering unit 4 preferably has only a single scattering disk 12.

Mittels der vorliegenden Streuvorrichtung 1 bleibt erfindungsgemäß beim Verstellen der Begrenzungseinrichtung 16 die Streubreite, in der das Streugut ausstreubar ist, konstant. Es wird lediglich die Richtung, in der das Streugut ausgeworfen ist, verstellt. Die Streubreite ist die Breite auf der Bodenfläche, auf der das Streugut beim einmaligen Überfahren ausgestreut wird.By means of the present spreading device 1, according to the invention, when adjusting the limiting device 16, the spreading width in which the spreading material can be spread remains constant. Only the direction in which the grit is ejected is adjusted. The spreading width is the width on the floor surface on which the spreading material is spread when it is driven over once.

Die Nachfülleinrichtung 8 dosiert vorzugsweise die Menge des Streuguts, die auf die Streuscheibe geführt wird. Das Streugut fällt vorzugsweise durch den Schacht 9 auf die Streuscheibe 12.The refilling device 8 preferably doses the amount of grit that is fed onto the diffuser. The spreading material preferably falls through the shaft 9 onto the spreading disc 12.
