- the cleaning liquid used is preferably water with chemical additives, in particular cleaning agents. However, it is also possible to use pure water, water with biological additives or other liquids. In such a cleaning device is understood at high pressure about 80 to 250 bar. For example, these pressures may vary depending on the power of a connected pump or cleaning task.
- Flat jet nozzles have a slot-shaped opening and produce a trapezoidal cleaning liquid jet in the side view.
- the nozzles are very precisely worked so that a defined spray wedge is created.
- the nozzles used are preferably high-pressure nozzles from the field of high-pressure and high-pressure water jet, for example for concrete restoration. Such high-pressure nozzles are designed for pressures of up to about 1500 bar and have a very high precision with respect to the spray wedge for the pressures used here.
- the spray wedge preferably has a very acute wedge angle, so that the impact area of the jet on the cleaning surface or the artificial turf surface is very narrow and the cleaning liquid impinges on the surface at a defined angle with as little scattering as possible.
- a cleansing liquid curtain is preferably to be understood as a closed curtain which may be considered to be approximately in a spray level.
- the cutting region of the cleaning liquid curtain with the cleaning plane has approximately a rectangular shape, wherein the width of the impact area is variable depending on the angle of incidence of the cleaning liquid curtain and ideally as low as possible.
- a receiving lamp In the direction of travel before the impact area a receiving lamp is arranged.
- a mixture of the cleaning agent and impurities is transported away from the artificial turf surface via the pickup lamp.

- the screw conveyor promotes in one direction, otherwise promotes the screw conveyor, for example, from the center to both sides.
- the transport screw can be inclined downwards in the conveying direction.
- the two areas are inclined to each other with different conveying direction. This can be achieved, for example, by means of split conveying screws, which can be driven separately or are coupled via a gearbox or universal joint.
- a vacuum generated via the suction connection prevails in the entire housing and thus also at the cleaning surface arranged below the housing.
- the cleaning surface is surrounded by a sealing strip.
- This sealing strip is arranged both in partial areas on the housing and on the receiving lamp.
- the sealing strip is preferably made of a plastic, in particular rubber. Different materials may preferably be used for the sealing strip in different areas.
- the inventive device for wet cleaning of artificial turf has at least one impeller.
- the wet cleaning device further has a coupling, with which it is connectable to the traction vehicle.
- the coupling may be, for example, a quick-change coupling or a fixed screw connection.
- a height level of the wet cleaning device is defined via the impeller and the coupling. This also applies to two attached to a front of the device wheels.
- the height level is understood in particular the height of the housing over the artificial turf and thus also the height of the washing bar and the receiving lamp. If several wheels are arranged one behind the other in the direction of travel, the height level is defined by the wheels.
- the washing bar with the flat jet nozzles is rotatable.
- the axis of rotation is for example on the central axis of the washing bar or near the cutting area of the spray wedges or the Spray level with the cleaning surface.
- the latter alternative has the advantage that the Sprühkeilin does not change upon rotation of the washing bar.
- About a rotation of the washing bar of the impact angle of the cleaning liquid curtain is adjustable to the cleaning surface.
- the impact angle is preferably continuously adjustable.
- the flow rate of the cleaning liquid curtain is high. This results from the fact that the kinetic energy of the cleaning liquid is mainly used to transport the particles out of the artificial turf.
- the cleaning depth and thus also the removal depth of impurities, especially sand, is relatively low.
- a change in the angle of incidence towards larger angles causes a reduction in the alluvium and an increase in the penetration or Abtragtiefe. Due to the precisely manufactured high-pressure nozzles and the resulting cleaning liquid curtain with a defined shape, the removal depth of the backfilling can be adjusted via the angle setting.
- a combination of several washing bars with different angles of incidence achieves high levels of alluvial capacity combined with high penetration depth.

- Such a change of one or more of the above-mentioned parameters is intended to be such that preferably the spray wedges of the individual flat jet nozzles do not overlap in the cleaning plane and that at least there is no distance between the individual spray wedges.
- a closed cleaning liquid curtain is created.
- a distance greater than zero from two adjacent spray wedges causes in the intermediate region insufficient cleaning of the Artificial turf, whereas overlaps lead to increased cleaning of the artificial turf.
- the flat jet nozzles are, of course, correspondingly adjustable.
- the Sprühkeilander can be varied, for example, by pivoting the flat jet nozzle in the spray level.
- a change in the Sprühkeilwinkel for example, by changing the slot length or the slot width of the flat jet nozzles, which are preferably also adjustable.
- the distance between the washing bar and the receiving lamp is preferably variable. This is intended in particular a defined distance between the impact area of the cleaning liquid curtain and the receiving lamp. Further preferably, the washing bar is variable in its distance from the receiving lamp.

- the cleaning liquid is sprayed into the housing so that the removal of dirt particles is improved.
- dirt particles are rinsed off the side walls of the housing or improves the transport properties of the screw.

On the one hand is thus adjustable that the cleaning surface is parallel to the artificial turf. On the other hand, the contact pressure of the sealing strips on the artificial turf can be changed. A change in the contact pressure is made in particular depending on the type of artificial turf.
- the coupling is preferably connected via a pendulum axis with the housing of the cleaning device.
- the wet cleaning device preferably has three wheels over which the level of the device is uniquely determined.
- Pendulum axles are, in particular, understood as meaning all axles which allow free movement of the device with respect to the traction vehicle, so that the level of the cleaning device is determined by its wheels. Since artificial grass surfaces are often uneven and fall off, for example, to the outline, thereby the entanglement between cleaning device and artificial turf surface is minimized or eliminated. Due to the constant level in connection with the wheels lifting of the individual artificial turf elements is prevented.
- the pendulum axis has a first axis of rotation in the direction of travel and a second axis of rotation orthogonal to the direction of travel.
- the level of the cleaning device is variable with respect to the level of the traction unit. This ensures that on uneven terrain, the wet cleaning device is defined as parallel to the artificial turf surface over the wheels.
- the various parameters of the cleaning device such as angle of incidence, ramp angle, screw speed, position of the washing bar and the receiving lamp via actuators are adjustable.
- Actuators in particular electric motors, linear actuators and hydraulic or pneumatic actuators are considered.
- the actuators are preferably controlled via switches from the locomotive.

- the wet cleaning device is connected to a traction unit.
- the coupling on the side of the traction vehicle is preferably height-adjustable.
- the height level of the wet cleaning device is adjustable or the cleaning device is liftable when it is not in operation.
- the level of the driveline coupling is defined by the cleaning apparatus.

- the suction connection of the cleaning device is connected via a suction line to a second pump in the traction vehicle.
- the second pump creates a vacuum and transports the mixture into a catch tank.
- the collecting tank and the storage tank can be connected, for example via a small sewage treatment plant, so that the cleaning liquid can be separated from the mixture and the supply tank can be fed again.
- Restrictive for such wet cleaning systems of artificial turfs is the total weight of the complete system. Many artificial turf surfaces can only handle a maximum weight of approx. 3 tons, so a significant factor in the selection of traction units and auxiliary equipment such as pumps and micro-clarifiers is the weight.
- the second pump for generating the negative pressure preferably has a fan.
- a Lüfterradpumpe has the advantages that the turbulence generated by it in the housing of the cleaning device compared to conventional pumps are considerably reduced.
- baffles or similar devices for air flow guidance or calming in the cleaning device can be dispensed with.
- the system for wet cleaning of artificial turf further preferably has a discharge device for backfilling.
- a discharge device for backfilling For example, sand or (plastic) granules are used as fillers.
- the artificial turf can be refitted after cleaning and abrading a filler layer of variable thickness.
- a cleaning fluid curtain with kinetic energy is applied at a first angle to the artificial turf.
- cleaning liquid curtain is, as already defined above, preferably understood a continuous curtain with finite thickness.

- the removal of impurities and the cleaning fluid from the artificial turf is supported by a negative pressure.
- the first and the second angle are adjusted to each other depending on the cleaning task. Different cleaning tasks result, for example, from different types of artificial turf, levels of contamination or backfilling of the artificial turf and the depth of removal of the filling.
- the properties of various spraying angles and ramp angles described above also apply to the method according to the invention.
- Such a method for wet cleaning artificial turf is preferably carried out with a device described above or a system described above.

Solche Höchstdruckdüsen sind für Drücke von bis ca. 1500 bar ausgelegt und weisen für die hier verwendeten Drücke eine sehr hohe Präzision in Bezug auf den Sprühkeil auf. Der Sprühkeil hat dabei vorzugsweise einen sehr spitzen Keilwinkel, sodass der Auftreffbereich des Strahls auf die Reinigungsfläche bzw. die Kunstrasenoberfläche sehr schmal ist und die Reinigungsflüssigkeit unter einem definierten Winkel mit möglichst geringer Streuung auf die Oberfläche auftrifft. Im Auftreffbereich bilden die Sprühkeile der einzelnen Flachstrahldüsen einen Reiningungsflüssigkeitsvorhang. Unter einem Reiningungsflüssigkeitsvorhang ist vorzugsweise ein geschlossener Vorhang zu verstehen, welcher näherungsweise als in einer Sprühebene befindlich angesehen werden kann. Der Schnittbereich des Reinigungsflüssigkeitsvorhangs mit der Reinigungsebene weist näherungsweise eine rechteckige Form auf, wobei die Breite des Auftreffbereichs in Abhängigkeit vom Auftreffwinkel des Reinigungsflüssigkeitsvorhangs variierbar und idealerweise möglichst gering ist.At the wash beam are spaced apart flat spray nozzles arranged rectified. Flat jet nozzles have a slot-shaped opening and produce a trapezoidal cleaning liquid jet in the side view. The nozzles are very precisely worked so that a defined spray wedge is created. The nozzles used are preferably high-pressure nozzles from the field of high-pressure and high-pressure water jet, for example for concrete restoration. Such high-pressure nozzles are designed for pressures of up to about 1500 bar and have a very high precision with respect to the spray wedge for the pressures used here. The spray wedge preferably has a very acute wedge angle, so that the impact area of the jet on the cleaning surface or the artificial turf surface is very narrow and the cleaning liquid impinges on the surface at a defined angle with as little scattering as possible. In the impact area, the spray wedges of the individual flat jet nozzles form a cleaning fluid curtain. A cleansing liquid curtain is preferably to be understood as a closed curtain which may be considered to be approximately in a spray level. The cutting region of the cleaning liquid curtain with the cleaning plane has approximately a rectangular shape, wherein the width of the impact area is variable depending on the angle of incidence of the cleaning liquid curtain and ideally as low as possible.
In Fahrtrichtung vor dem Auftreffbereich ist eine Aufnahmerampe angeordnet. Über die Aufnahmerampe wird ein Gemisch aus dem Reinigungsmittel und Verunreinigungen von der Kunstrasenoberfläche abtransportiert. Das Gemisch kann flüssige, feste und gasförmige Bestandteile aufweisen. Als Verunreinigungen werden in diesem Zusammenhang insbesondere Schmutzpartikel, Pflanzenreste oder Pflanzen wie Moose und auch eine bewusst auf den Kunstrasen aufgebrachte Verfüllung aus beispielsweise Granulat oder Sand, welche zumindest an der Oberfläche ebenfalls verschmutzt ist, angesehen. Die Aufnahmerampe geht in eine Aufnahme für eine Transportschnecke über. Die Transportschnecke ist vorzugsweise quer zur Fahrtrichtung angeordnet und fördert das Gemisch zu einem Absauganschluss. Dabei ist auf einer Seite des Gehäuses oder beidseitig am Gehäuse ein Absauganschluss angeordnet. Im Falle von einem Absauganschluss fördert die Transportschnecke in eine Richtung, andernfalls fördert die Transportschnecke beispielsweise von der Mitte zu beiden Seiten hin. Zur Unterstützung der Förderleistung kann die Transportschnecke in Förderrichtung nach unten geneigt sein. Bei zwei Absauganschlüssen sind die beiden Bereiche mit unterschiedlicher Förderrichtung zueinander geneigt. Dies ist beispielsweise durch geteilte Förderschnecken, welche getrennt antreibbar sind oder über ein Getriebe oder Kreuzgelenk gekoppelt sind, realisierbar. Ein über den Absauganschluss erzeugter Unterdruck herrscht im gesamten Gehäuse und somit auch an der unterhalb des Gehäuses angeordneten Reinigungsfläche. Zur Erhöhung der Saugleistung ist die Reinigungsfläche mit einer Dichtleiste umgeben. Diese Dichtleiste ist dabei sowohl in Teilbereichen am Gehäuse als auch an der Aufnahmerampe angeordnet. Die Dichtleiste besteht vorzugsweise aus einem Kunststoff, insbesondere aus Gummi. Für die Dichtleiste sind in unterschiedlichen Bereichen vorzugsweise unterschiedliche Materialien verwendbar.In the direction of travel before the impact area a receiving lamp is arranged. A mixture of the cleaning agent and impurities is transported away from the artificial turf surface via the pickup lamp. The mixture can be liquid, solid and gaseous components exhibit. As impurities are in this context, in particular dirt particles, plant residues or plants such as mosses and a conscious on the artificial turf applied backfilling of, for example, granules or sand, which is also contaminated at least on the surface viewed. The pickup lamp goes into a receptacle for a screw conveyor. The transport screw is preferably arranged transversely to the direction of travel and conveys the mixture to a suction connection. In this case, a suction connection is arranged on one side of the housing or on both sides of the housing. In the case of a suction port, the screw conveyor promotes in one direction, otherwise promotes the screw conveyor, for example, from the center to both sides. To support the conveying capacity, the transport screw can be inclined downwards in the conveying direction. With two suction connections, the two areas are inclined to each other with different conveying direction. This can be achieved, for example, by means of split conveying screws, which can be driven separately or are coupled via a gearbox or universal joint. A vacuum generated via the suction connection prevails in the entire housing and thus also at the cleaning surface arranged below the housing. To increase the suction power, the cleaning surface is surrounded by a sealing strip. This sealing strip is arranged both in partial areas on the housing and on the receiving lamp. The sealing strip is preferably made of a plastic, in particular rubber. Different materials may preferably be used for the sealing strip in different areas.
Die erfindungsgemäße Vorrichtung zum Nassreinigen von Kunstrasen weist zumindest ein Laufrad auf. Die Nassreinigungsvorrichtung weist ferner eine Kupplung auf, mit welcher sie mit dem Triebfahrzeug verbindbar ist. Bei der Kupplung kann es sich beispielsweise um eine Schnellwechselkupplung oder auch um eine feste Schraubverbindung handeln. Bei einem einzigen Laufrad wird ein Höhenniveau der Nassreinigungsvorrichtung über das Laufrad und die Kupplung definiert. Dies gilt ebenso bei zwei an einer Vorderseite der Vorrichtung angebrachten Rädern. Als Höhenniveau wird insbesondere die Höhe des Gehäuses über dem Kunstrasen und damit auch die Höhe des Waschbalkens und der Aufnahmerampe verstanden. Sind mehrere Laufräder in Fahrtrichtung hintereinander angeordnet, ist das Höhenniveau durch die Laufräder definiert. Bei einer solchen Ausführung mit mehreren in Fahrtrichtung hintereinander angeordneten Laufrädern oder einer Ausführung mit einem einzigen Laufrad wird ein seitliches Verkippen der Vorrichtung von einer drehstarren Kupplung bzw. Verbindung mit dem Triebfahrzeug unterbunden. Bei drei oder mehr in Fahrtrichtung nicht linear angeordneten Laufrädern ist das Höhenniveau der Vorrichtung in Bezug auf eine Kunstrasenfläche durch die Laufräder eindeutig definiert.The inventive device for wet cleaning of artificial turf has at least one impeller. The wet cleaning device further has a coupling, with which it is connectable to the traction vehicle. The coupling may be, for example, a quick-change coupling or a fixed screw connection. In a single impeller, a height level of the wet cleaning device is defined via the impeller and the coupling. This also applies to two attached to a front of the device wheels. The height level is understood in particular the height of the housing over the artificial turf and thus also the height of the washing bar and the receiving lamp. If several wheels are arranged one behind the other in the direction of travel, the height level is defined by the wheels. In such a design with several consecutively arranged in the direction of travel wheels or a design with a single impeller lateral tilting of the device is prevented by a rigid coupling or connection to the locomotive. With three or more non-linearly arranged impellers in the direction of travel, the height level of the device with respect to an artificial turf surface is uniquely defined by the impellers.
Der Waschbalken mit den Flachstrahldüsen ist drehbar. Die Drehachse liegt beispielsweise auf der Mittelachse des Waschbalkens oder nahe dem Schnittbereich der Sprühkeile bzw. der Sprühebene mit der Reinigungsfläche. Die letztgenannte Alternative hat den Vorteil, dass sich die Sprühkeillänge bei Verdrehung des Waschbalkens nicht ändert. Über eine Verdrehung des Waschbalkens ist der Auftreffwinkel des Reinigungsflüssigkeitsvorhangs auf die Reinigungsfläche einstellbar. Der Auftreffwinkel ist vorzugsweise kontinuierlich einstellbar. Bei einem flachen Auftreffwinkel, bei welchem die Reinigungsflüssigkeit eine hohe Geschwindigkeit in Fahrtrichtung aufweist, ist die Schwemmleistung des Reinigungsflüssigkeitsvorhangs hoch. Dies resultiert daraus, dass die kinetische Energie der Reinigungsflüssigkeit vorwiegend dazu verwendet wird, die Partikel aus dem Kunstrasen abzutransportieren. Bei einem flachen Auftreffwinkel ist die Reinigungstiefe und somit auch die Abtragtiefe von Verunreinigungen, insbesondere von Sand, relativ gering. Eine Veränderung des Auftreffwinkels hin zu größeren Winkeln bewirkt eine Verringerung der Schwemmleistung und eine Erhöhung der Eindring- bzw. Abtragtiefe. Aufgrund der präzise gefertigten Hochdruckdüsen und des daraus resultierenden Reinigungsflüssigkeitsvorhangs mit definierter Form kann über die Winkeleinstellung die Abtragtiefe der Verfüllung eingestellt werden.The washing bar with the flat jet nozzles is rotatable. The axis of rotation is for example on the central axis of the washing bar or near the cutting area of the spray wedges or the Spray level with the cleaning surface. The latter alternative has the advantage that the Sprühkeillänge does not change upon rotation of the washing bar. About a rotation of the washing bar of the impact angle of the cleaning liquid curtain is adjustable to the cleaning surface. The impact angle is preferably continuously adjustable. At a flat angle of incidence, at which the cleaning liquid has a high speed in the direction of travel, the flow rate of the cleaning liquid curtain is high. This results from the fact that the kinetic energy of the cleaning liquid is mainly used to transport the particles out of the artificial turf. At a flat impact angle, the cleaning depth and thus also the removal depth of impurities, especially sand, is relatively low. A change in the angle of incidence towards larger angles causes a reduction in the alluvium and an increase in the penetration or Abtragtiefe. Due to the precisely manufactured high-pressure nozzles and the resulting cleaning liquid curtain with a defined shape, the removal depth of the backfilling can be adjusted via the angle setting.
Über eine Kombination von mehreren Waschbalken mit unterschiedlichen Auftreffwinkeln sind hohe Schwemmleistungen in Verbindung mit hoher Eindringtiefe erreichbar. Weiter vorzugsweise ist die Höhe des Waschbalkens in Bezug auf die Reinigungsfläche verstellbar. Darüber kann zum einen die kinetische Energie des Reinigungsflüssigkeitsvorhangs verändert werden; zum anderen kann hierüber bei Veränderung des Aufreffwinkels gegebenenfalls der Abstand zur Reinigungsfläche nahezu konstant gehalten werden.A combination of several washing bars with different angles of incidence achieves high levels of alluvial capacity combined with high penetration depth. Further preferably, the height of the washing bar is adjustable with respect to the cleaning surface. In addition, on the one hand, the kinetic energy of the cleaning liquid curtain can be changed; On the other hand, if necessary, the distance to the cleaning surface can be kept almost constant when changing the angle of incidence.
Weiter ist die Aufnahmerampe in ihrer Neigung verstellbar. Vorzugsweise ist die Aufnahmerampe höhenverstellbar. Insbesondere bei einer gezielten Verstellung des Rampenwinkels, beispielsweise in Abhängigkeit vom Auftreffwinkel oder von der Beschaffenheit des Kunstrasens ist ein optimaler Abtransport des Gemisches aus Reinigungsflüssigkeit und Verschmutzungen realisierbar. Über die Höhenverstellbarkeit der Rampe besteht die Möglichkeit, das Niveau des unteren Rampenendes bei Veränderung des Rampenwinkels konstant zu halten.Next, the recording lamp is adjustable in its inclination. Preferably, the receiving lamp is height adjustable. In particular, in a targeted adjustment of the ramp angle, for example, depending on the angle of incidence or the nature of the artificial turf an optimal removal of the mixture of cleaning fluid and contaminants can be realized. The height adjustability of the ramp allows the level of the lower end of the ramp to be kept constant as the ramp angle changes.
Vorzugsweise sind die Flachstrahldüsen bezüglich ihres Abstands zueinander, bezüglich ihrer Sprühkeillänge und/oder des Sprühkeilwinkels verstellbar. Über eine solche Veränderung einer oder mehrerer der oben genannten Parameter soll bezweckt werden, dass sich vorzugsweise die Sprühkeile der einzelnen Flachstrahldüsen in der Reinigungsebene nicht überschneiden und dass zumindest dort kein Abstand zwischen den einzelnen Sprühkeilen entsteht. Somit wird ein geschlossener Reinigungsflüssigkeitsvorhang geschaffen. Ein Abstand größer Null von zwei benachbarten Sprühkeilen bewirkt in dem Zwischenbereich eine ungenügende Reinigung des Kunstrasens, wohingegen Überdeckungen zu einer erhöhten Reinigung des Kunstrasens führen. Diese beiden Varianten werden als nachteilig angesehen, da sich dadurch ein Streifenmuster auf dem gereinigten Kunstrasen bilden kann. Soll ein solches Streifenmuster aufgebracht werden, sind die Flachstrahldüsen natürlich entsprechend justierbar. Die Sprühkeillänge ist beispielweise durch Verschwenken der Flachstrahldüse in der Sprühebene variierbar. Eine Veränderung der Sprühkeilwinkel erfolgt beispielsweise durch eine Veränderung der Schlitzlänge oder der Schlitzbreite der Flachstrahldüsen, welche vorzugsweise auch einstellbar sind.Preferably, the flat jet nozzles with respect to their distance from each other, with respect to their Sprühkeillänge and / or the Sprühkeilwinkels adjustable. Such a change of one or more of the above-mentioned parameters is intended to be such that preferably the spray wedges of the individual flat jet nozzles do not overlap in the cleaning plane and that at least there is no distance between the individual spray wedges. Thus, a closed cleaning liquid curtain is created. A distance greater than zero from two adjacent spray wedges causes in the intermediate region insufficient cleaning of the Artificial turf, whereas overlaps lead to increased cleaning of the artificial turf. These two variants are considered disadvantageous, as this can form a striped pattern on the cleaned artificial turf. If such a striped pattern is to be applied, the flat jet nozzles are, of course, correspondingly adjustable. The Sprühkeillänge can be varied, for example, by pivoting the flat jet nozzle in the spray level. A change in the Sprühkeilwinkel for example, by changing the slot length or the slot width of the flat jet nozzles, which are preferably also adjustable.
Der Abstand zwischen dem Waschbalken und der Aufnahmerampe ist vorzugsweise veränderbar. Dies bezweckt insbesondere einen definierten Abstand zwischen dem Auftreffbereich des Reinigungsflüssigkeitsvorhangs und der Aufnahmerampe. Weiter vorzugsweise ist der Waschbalken in seinem Abstand zur Aufnahmerampe veränderbar. Der Abstand des Waschbalkens ist dabei je nach Ausführungsform unabhängig oder abhängig von der Höhe des Waschbalkens über der Reinigungsfläche oder seiner Verdrehung einstellbar. Eine abhängige Verstellung bewirkt beispielsweise einen vorzugsweise nahezu konstanten Abstand zwischen Auftreffbereich und Aufnahmerampe.The distance between the washing bar and the receiving lamp is preferably variable. This is intended in particular a defined distance between the impact area of the cleaning liquid curtain and the receiving lamp. Further preferably, the washing bar is variable in its distance from the receiving lamp. The distance of the washing bar is depending on the embodiment independently or dependent on the height of the washing bar on the cleaning surface or its rotation adjustable. A dependent adjustment causes, for example, a preferably almost constant distance between the impact area and the receiving lamp.
Vorzugsweise sind oberhalb der zumindest einen Transportschnecke eine oder mehrere Düsen angeordnet. Über die Düsen wird die Reinigungsflüssigkeit derart in das Gehäuse eingesprüht, dass der Abtransport von Schmutzpartikeln verbessert wird. Dabei werden beispielsweise Schmutzpartikel von den Seitenwänden des Gehäuses abgespült oder die Transporteigenschaften der Schnecke verbessert.Preferably, one or more nozzles are arranged above the at least one transport screw. About the nozzles, the cleaning liquid is sprayed into the housing so that the removal of dirt particles is improved. In this case, for example, dirt particles are rinsed off the side walls of the housing or improves the transport properties of the screw.
Das zumindest eine Laufrad und das Gehäuse sind weiter vorzugsweise relativ zueinander höhenverstellbar. Über eine solche Verstellung wird das Niveau der Nassreinigungsvorrichtung verändert. Zum einen ist somit einstellbar, dass sich die Reinigungsfläche parallel zum Kunstrasen befindet. Zum anderen ist hierüber der Anpressdruck der Dichtleisten auf den Kunstrasen veränderbar. Eine Veränderung des Anpressdrucks wird insbesondere in Abhängigkeit von der Art des Kunstrasens vorgenommen.The at least one impeller and the housing are further preferably height-adjustable relative to one another. Such an adjustment will change the level of the wet cleaning device. On the one hand is thus adjustable that the cleaning surface is parallel to the artificial turf. On the other hand, the contact pressure of the sealing strips on the artificial turf can be changed. A change in the contact pressure is made in particular depending on the type of artificial turf.
Die Kupplung ist vorzugsweise über eine Pendelachse mit dem Gehäuse der Reinigungseinrichtung verbunden. In Verbindung mit der Pendelachse weist die Nassreinigungsvorrichtung vorzugsweise drei Laufräder auf, über welche das Niveau der Vorrichtung eindeutig bestimmt ist. Als Pendelachsen werden insbesondere alle Achsen verstanden, welche eine freie Beweglichkeit der Vorrichtung in Bezug auf das Triebfahrzeug zulassen, sodass das Niveau der Reinigungsvorrichtung über ihre Laufräder bestimmt wird. Da Kunstrasenflächen häufig uneben sind und beispielsweise zu den Außenlinien abfallen, wird hierdurch die Verschränkung zwischen Reinigungsvorrichtung und Kunstrasenfläche minimiert bzw. eliminiert. Durch das konstante Niveau in Verbindung mit den Laufrädern wird ein Anheben der einzelnen Kunstrasenelemente unterbunden. Vorzugsweise weist die Pendelachse eine erste Drehachse in Fahrtrichtung und eine zweite Drehachse orthogonal zur Fahrtrichtung auf. Zudem ist das Niveau der Reinigungsvorrichtung in Bezug auf das Niveau des Triebfahrzeugs veränderbar. Somit ist gewährleistet, dass in unebenem Gelände die Nassreinigungsvorrichtung möglichst parallel zur Kunstrasenfläche über die Laufräder definiert ist.The coupling is preferably connected via a pendulum axis with the housing of the cleaning device. In conjunction with the pendulum axis, the wet cleaning device preferably has three wheels over which the level of the device is uniquely determined. Pendulum axles are, in particular, understood as meaning all axles which allow free movement of the device with respect to the traction vehicle, so that the level of the cleaning device is determined by its wheels. Since artificial grass surfaces are often uneven and fall off, for example, to the outline, thereby the entanglement between cleaning device and artificial turf surface is minimized or eliminated. Due to the constant level in connection with the wheels lifting of the individual artificial turf elements is prevented. Preferably, the pendulum axis has a first axis of rotation in the direction of travel and a second axis of rotation orthogonal to the direction of travel. In addition, the level of the cleaning device is variable with respect to the level of the traction unit. This ensures that on uneven terrain, the wet cleaning device is defined as parallel to the artificial turf surface over the wheels.
Vorzugsweise sind die verschiedenen Parameter der Reinigungsvorrichtung wie beispielsweise Auftreffwinkel, Rampenwinkel, Schneckendrehzahl, Position des Waschbalkens und der Aufnahmerampe über Aktoren einstellbar. Als Aktoren werden insbesondere Elektromotoren, Linearantriebe und hydraulische oder pneumatische Aktoren angesehen. Die Aktoren sind vorzugsweise über Schalter aus dem Triebfahrzeug ansteuerbar.Preferably, the various parameters of the cleaning device such as angle of incidence, ramp angle, screw speed, position of the washing bar and the receiving lamp via actuators are adjustable. Actuators in particular electric motors, linear actuators and hydraulic or pneumatic actuators are considered. The actuators are preferably controlled via switches from the locomotive.
Ein System zum Reinigen von Kunstrasen weist eine Ausführungsform der oben beschriebenen Nassreinigungsvorrichtung auf. Über die Kupplung ist die Nassreinigungsvorrichtung mit einem Triebfahrzeug verbunden. Die Kupplung auf Seiten des Triebfahrzeugs ist vorzugsweise höhenverstellbar. Somit ist beispielsweise das Höhenniveau der Nassreinigungsvorrichtung einstellbar oder die Reinigungsvorrichtung ist anhebbar, wenn sie nicht in Betrieb ist. Im Betrieb wird bei einer Nassreinigungsvorrichtung, bei welcher das Höhenniveau der Vorrichtung durch die Laufräder definiert wird, das Niveau der triebfahrzeugsseitigen Kupplung von der Reinigungsvorrichtung definiert. Der Hochdruckanschluss der Reinigungspumpe ist über eine Hochdruckleitung mit einer Pumpe im Triebfahrzeug verbunden. Die Pumpe saugt Reinigungsflüssigkeit aus einem Vorratstank an und stellt einen vorzugsweise variablen Hochdruck für die Reinigungsvorrichtung bereit. Der Absauganschluss der Reinigungsvorrichtung ist über eine Absaugleitung mit einer zweiten Pumpe im Triebfahrzeug verbunden. Die zweite Pumpe erzeugt einen Unterdruck und transportiert das Gemisch in einen Auffangtank. Der Auffangtank und der Vorratstank sind beispielsweise über ein Kleinstklärwerk verbindbar, sodass die Reinigungsflüssigkeit aus dem Gemisch abgeschieden werden kann und dem Vorratstank wieder zuführbar ist. Einschränkend für solche Nassreinigungssysteme von Kunstrasen ist dabei das Gesamtgewicht des kompletten Systems. Viele Kunstrasenflächen sind maximal mit einem Gesamtgewicht von ca. 3 Tonnen belastbar, sodass ein maßgeblicher Faktor für die Auswahl von Triebfahrzeugen sowie der Zusatzaggregate wie Pumpen und Kleinstklärwerk das Gewicht ist.A system for cleaning artificial turf has an embodiment of the above-described wet cleaning apparatus. About the coupling, the wet cleaning device is connected to a traction unit. The coupling on the side of the traction vehicle is preferably height-adjustable. Thus, for example, the height level of the wet cleaning device is adjustable or the cleaning device is liftable when it is not in operation. In operation, in a wet cleaning apparatus in which the height level of the apparatus is defined by the wheels, the level of the driveline coupling is defined by the cleaning apparatus. The high-pressure connection of the cleaning pump is connected via a high-pressure line to a pump in the locomotive. The pump sucks cleaning liquid from a storage tank and provides a preferably variable high pressure for the cleaning device. The suction connection of the cleaning device is connected via a suction line to a second pump in the traction vehicle. The second pump creates a vacuum and transports the mixture into a catch tank. The collecting tank and the storage tank can be connected, for example via a small sewage treatment plant, so that the cleaning liquid can be separated from the mixture and the supply tank can be fed again. Restrictive for such wet cleaning systems of artificial turfs is the total weight of the complete system. Many artificial turf surfaces can only handle a maximum weight of approx. 3 tons, so a significant factor in the selection of traction units and auxiliary equipment such as pumps and micro-clarifiers is the weight.
Die zweite Pumpe zur Erzeugung des Unterdrucks weist vorzugsweise ein Lüfterrad auf. Eine Lüfterradpumpe hat dahingehend Vorteile, dass die von ihr erzeugten Verwirbelungen im Gehäuse der Reinigungsvorrichtung im Vergleich zu konventionellen Pumpen erheblich reduzierbar sind. Somit sind beispielsweise Prallbleche oder ähnliche Vorrichtungen zur Luftstromführung bzw. -beruhigung in der Reinigungsvorrichtung entbehrlich.The second pump for generating the negative pressure preferably has a fan. A Lüfterradpumpe has the advantages that the turbulence generated by it in the housing of the cleaning device compared to conventional pumps are considerably reduced. Thus, for example, baffles or similar devices for air flow guidance or calming in the cleaning device can be dispensed with.
Das System zum Nassreinigen von Kunstrasen weist weiter vorzugsweise eine Austragvorrichtung für die Verfüllung auf. Als Verfüllstoff wird beispielsweise Sand oder (Kunststoff-)Granulat verwendet. Somit kann der Kunstrasen nach dem Reinigen und Abtragen einer Verfüllschicht mit variabler Dicke neu versehen werden.The system for wet cleaning of artificial turf further preferably has a discharge device for backfilling. For example, sand or (plastic) granules are used as fillers. Thus, the artificial turf can be refitted after cleaning and abrading a filler layer of variable thickness.
Bei einem Verfahren zum Nassreinigen von Kunstrasen wird ein Reinigungsflüssigkeitsvorhang mit kinetischer Energie unter einem ersten Winkel auf den Kunstrasen aufgebracht. Als Reinigungsflüssigkeitsvorhang wird, wie oben bereits definiert, vorzugsweise ein durchgängiger Vorhang mit endlicher Dicke verstanden. Durch die kinetische Energie des Reinigungsflüssigkeitsvorhangs werden Verunreinigungen aus dem Kunstrasen ausgeschwemmt bzw. entfernt und über eine Aufnahmerampe, welche unter einem zweiten Winkel geneigt ist, abtransportiert. Der Abtransport der Verunreinigungen sowie der Reinigungsflüssigkeit aus dem Kunstrasen wird von einem Unterdruck unterstützt. Der erste und der zweite Winkel werden dabei in Abhängigkeit von der Reinigungsaufgabe zueinander eingestellt. Unterschiedliche Reinigungsaufgaben resultieren beispielsweise aus unterschiedlichen Kunstrasenarten, Verschmutzungsgraden bzw. Verfüllungen des Kunstrasens und die Abtragtiefe der Verfüllung. Die zuvor beschriebenen Eigenschaften verschiedener Spritzwinkel und Rampenwinkel gelten ebenfalls für das erfindungsgemäße Verfahren. Bei normal verschmutzten Kunstrasenflächen werden beispielsweise folgende Spritzwinkel und Rampenwinkel für verschiedene Reinigungsaufgaben verwendet:
Ein solches Verfahren zum Nassreinigen von Kunstrasen ist vorzugsweise mit einer oben beschriebenen Vorrichtung bzw. einem oben beschriebenen System durchführbar.Such a method for wet cleaning artificial turf is preferably carried out with a device described above or a system described above.

Unterhalb des Gehäuses 10 ist eine Reinigungsfläche 20 definiert. Die Reinigungsfläche 20 ist im Betrieb im Wesentlichen parallel zur Kunstrasenoberfläche bzw. ein Teil der Kunstrasenoberfläche und wird von Dichtleisten 22 umgeben. Im Gehäuse 10 ist ein Waschbalken 30 angeordnet. Der Waschbalken 30 steht mit einem Hochdruckanschluss 34 in Verbindung, über welchen dem Waschbalken 30 eine unter Hochdruck stehende Reinigungsflüssigkeit zugeführt wird. Am Waschbalken 30 sind beabstandet voneinander Flachstrahldüsen 32 angeordnet. Die Flachstrahldüsen 32 sind derart angeordnet, dass die aus den Flachstrahldüsen 32 austretende Reinigungsflüssigkeit als ein Reinigungsflüssigkeitsvorhang die Reinigungsfläche 20 in einem Auftreffbereich 33 schneidet. Dabei sind die Flachstrahldüsen 32 derart beabstandet auf dem Waschbalken 30 angeordnet, dass sich die Sprühkeile der einzelnen Flachstrahldüsen 32 nicht überschneiden und dass sich auch keine Lücken zwischen den einzelnen Sprühkeilen in einem Schnittbereich mit der Reinigungsfläche 20 bilden. Unter Schnittbereich wird hier der Bereich definiert, in welchem die gedachte Ebene des Reinigungsflüssigkeitskeiles sich mit der gedachten Ebene der Reinigungsfläche 20 schneiden, d. h. der Auftreffbereich 33 des Reinigungsstrahlkeiles auf der Reinigungsfläche 20. Somit entsteht im Auftreffbereich 33 auf den Kunstrasen ein geschlossener Reinigungsflüssigkeitsvorhang. Der Reinigungsflüssigkeitsvorhang schneidet dabei unter einem Winkel α die Reinigungsfläche 20.Below the

Durch die Veränderung des Winkels α ist insbesondere die Reinigungstiefe im Kunstrasen veränderbar. Bei spitzem Auftreffwinkel α wird der Kunstrasen lediglich oberflächlich gereinigt, und die Abtragung von Verfüllungen aus dem Kunstrasen erfolgt ebenfalls oberflächlich. Bei stumpferem Auftreffwinkel α erfolgt die Reinigung des Kunstrasens tiefgründiger, und mehr Verfüllung wird aus dem Kunstrasen abgetragen. Über die kinetische Energie der Reinigungsflüssigkeit wird ein Gemisch aus Reinigungsflüssigkeit, Verfüllung und Verschmutzungen des Kunstrasens über die Aufnahmerampe 40 abtransportiert. Der Rampenwinkel β wird in Abhängigkeit vom Auftreffwinkel α verstellt, sodass ein optimaler Abtransport des Gemisches erfolgt. Der Abtransport des Gemisches wird von einem Unterdruck unterstützt, welcher im Gehäuse herrscht. Zur Erzeugung des Unterdrucks über einen Absauganschluss 42 ist das Gehäuse zur Reinigungsfläche 20 hin mit Dichtleisten 22 aus Kunststoff abgedichtet. Im vorderen Bereich des Gehäuses, welcher trotz des Ausbruchs nicht einsehbar ist, ist auf der Aufnahmerampe 40 eine Transportschnecke 50 angeordnet, welche das Gemisch in Richtung des Absauganschlusses auf abtransportiert. Im Bereich eines der Enden der Transportschnecke 50 ist der Absauganschluss 52 angeordnet, über welchen das Gemisch abtransportiert wird.By changing the angle α in particular the cleaning depth in the artificial turf is changeable. At an acute angle of incidence α, the artificial turf is only superficially cleaned, and the removal of fillings from the artificial turf is also superficial. At a blunter impact angle α, the cleaning of the artificial turf takes place more profoundly, and more filling is removed from the artificial turf. About the kinetic energy of the cleaning liquid, a mixture of cleaning fluid, backfilling and contamination of the artificial turf is removed via the receiving
