- Suction channel includes, and a water system with a water tank, a water pump and at least one of the sweeping unit or the sweeping receiving unit associated water spray nozzle, wherein a controller with at least on the broom drive, the suction fan and the water pump and / or at least one water valve acting control unit is provided.
- Such sweepers are commonly known - in the case of their design for the cleaning of roads commonly referred to as street sweepers.
- water is sprayed in the area of the at least one rotating broom. This serves to bind swirled-up dust and provides a means to reduce dust pollution in the environment when sweepers are used.

Description
Die vorliegende Erfindung betrifft eine selbstfahrende aufnehmende Kehrmaschine mit einem Trägerfahrzeug, einer Kehreinheit mit mindestens einen rotierend angetriebenen Besen, einer Kehrgut-Aufnahmeeinheit, welche einen Kehrgut-Sammelbehälter mit einem Sauggebläse und einen Kehrgut-Ansaugtrakt mit einem Saugkopf und einem in den Kehrgut-Sammelbehälter mündenden Saugkanal umfasst, und einem Wassersystem mit einem Wassertank, einer Wasserpumpe und mindestens einer der Kehreinheit oder der Kehrgut-Aufnahmeeinheit zugeordneten Wasser-Sprühdüse, wobei eine Steuerung mit einer mindestens auf den Besenantrieb, das Sauggebläse und die Wasserpumpe und/oder mindestens ein Wasserventil wirkenden Steuereinheit vorgesehen ist.The present invention relates to a self-propelled picking sweeper with a carrier vehicle, a sweeping unit with at least one rotatably driven broom, a sweeping material receiving unit which a sweepings collecting container with a suction fan and a sweeping material intake tract with a suction head and opening into the debris collection container Suction channel includes, and a water system with a water tank, a water pump and at least one of the sweeping unit or the sweeping receiving unit associated water spray nozzle, wherein a controller with at least on the broom drive, the suction fan and the water pump and / or at least one water valve acting control unit is provided.
Derartige Kehrmaschinen sind - im Falle ihrer Ausführung für die Reinigung von Straßen landläufig als Straßenkehrmaschinen bezeichnet - allgemein bekannt. Mittels des Wassersystems wird dabei beispielsweise Wasser im Bereich des mindestens einen rotierenden Besens verdüst. Dies dient dazu, aufgewirbelten Staub zu binden, und stellt eine Maßnahme dar, um die beim Einsatz von Kehrmaschinen auftretende Belastung der Umgebung mit Staubpartikeln zu reduzieren. Zusätzlich oder alternativ kann Wasser auch an anderer Stelle (z. B. im Bereich des Ansaugtrakts) verdüst werden, um Staub zu binden und Staubemissionen über die Ablauft der Kehrmaschine zu reduzieren.Such sweepers are commonly known - in the case of their design for the cleaning of roads commonly referred to as street sweepers. By means of the water system, for example, water is sprayed in the area of the at least one rotating broom. This serves to bind swirled-up dust and provides a means to reduce dust pollution in the environment when sweepers are used. Additionally or alternatively, water may also be atomized elsewhere (eg in the area of the intake tract) in order to bind dust and reduce dust emissions via the sweeper's run-off.
Die potentielle Gesundheitsgefährdung durch Staubpartikel, insbesondere wenn es sich hierbei um (lungengängigen) sog. Feinstaub handelt, ist Anlass für umfassende Bemühungen, die Staubbelastung der Luft zu reduzieren. Auch die von Kehrmaschinen der hier in Rede stehenden Art ausgehenden Staubemissionen unterliegen zunehmend strenger werdenden Beschränkungen. So werden - unter Verfolgung unterschiedlicher Ansätze - verschiedene technische Maßnahmen ergriffen. Beispielsweise befasst sich die
Mit solchen Maßnahmen sind nicht nur (teilweise ganz erhebliche) Mehrkosten für die Herstellung bzw. Anschaffung und/oder für den Betrieb der jeweiligen Kehrmaschine verbunden. Auch sind in der Praxis im Hinblick auf die Reduzierung von Staubemissionen die erzielbaren Nettoerfolge geringer als erhofft. Dies hängt mit verschiedenen Faktoren zusammen. So ist beispielsweise bei dem Betrieb der Kehrmaschinen mit einem Wasserüberschuss der (begrenzte) verfügbare Wasservorrat schneller erschöpft, d. h. für den jeweiligen Kehreinsatz steht nur eine geringere Reichweite zur Verfügung, bevor die Kehrmaschine (typischerweise im Depot) Wasser nachtanken muss. Die Folge sind vermehrte unproduktive Leerfahrten, welche nicht nur (zusätzlich zu den Wasserkosten) die Wirtschaftlichkeit weiter mindern, sondern auch mit zusätzlichen Emissionen durch den Fahrzeugantrieb verbunden sind. Entsprechendes gilt für der Staubabscheidung dienende Einbauten der Kehrgut-Aufnahmeeinheit, welche zu Lasten des Fassungsvermögens des Kehrgut-Sammelbehälters gehen; denn auch diese führen zu einer Beschränkung der Reichweite des jeweiligen Kehreinsatzes, bevor die Kehrmaschine zur Entleerung des Kehrgut-Sammelbehälters eine Deponie bzw. sonstige Entsorgungseinrichtung anfahren muss. Ein - aufgrund des Betriebs der Kehrmaschine mit einem Wasserüberschuss - nasses Kehrgut verursacht zudem Probleme bei der Entsorgung. Erst recht bei einem entsprechend erhöhten Feuchtigkeitsgehalt des aus der Abluft heraus zu filternden Staubes steigt zudem die ohnehin erhebliche Gefahr einer Verstopfung von Feinfiltern für die aus dem Kehrgut-Sammelbehälter abgeführte Abluft. Die Folge sind nicht nur Funktionsausfälle, sondern zudem im erhöhten Maße unproduktive, mit zusätzlichen Abgasemissionen verbundene Werkstatt- und Wartungsfahrten, von dem hohen Wartungsaufwand für den regelmäßigen Filterwechsel ganz zu schweigen.With such measures not only (sometimes very significant) additional costs for the production or purchase and / or for the operation of the respective sweeper are connected. Also, in practice, with regard to the reduction of dust emissions, the net achievements that can be achieved are less than hoped for. This is related to various factors. For example, in the operation of sweepers with a water surplus of (limited) available water supply is exhausted faster, ie for the respective sweeping use is only a smaller range available before the sweeper (typically in the depot) has to refuel water. The result is increased unproductive empty runs, which not only (in addition to the water costs) further reduce the economy, but are also associated with additional emissions from the vehicle drive. The same applies to the dust collecting internals of the debris receiving unit, which are at the expense of the capacity of the debris collection container go; because these also lead to a limitation of the range of the respective sweeping operation before the sweeper has to start a landfill or other disposal facility for emptying the sweepings collection container. A wet rubbish due to the operation of the sweeper with an excess of water also causes problems in disposal. Even more so with a correspondingly increased moisture content of the dust to be filtered out of the exhaust also increases the already considerable risk of clogging of fine filters for the discharged from the debris collection exhaust air. The result is not only functional failures, but also to a greater extent unproductive, associated with additional exhaust emissions workshop and maintenance trips, not to mention the high maintenance requirements for the regular filter change.
Im Lichte des vorstehend dargelegten Standes der Technik und der mit diesem verbundenen Nachteile ist die vorliegende Erfindung darauf gerichtet, eine Kehrmaschine der eingangs genanten Art bereitzustellen, welche sich in dem Sinne durch eine besonders hohe Praxistauglichkeit auszeichnet, dass selbst strenge Anforderungen hinsichtlich der Staubemissionen erfüllt werden, ohne dass - verglichen mit dem Stand der Technik - die Wirtschaftlichkeit und die Zuverlässigkeit der Kehrmaschine nennenswert darunter leidet und/oder Einbußen hinsichtlich der Reichweite mit der Notwenigkeit vermehrter unproduktiver Leerfahrten die Folge sind.In the light of the above-mentioned prior art and the associated disadvantages, the present invention is directed to provide a sweeper of the type mentioned, which is characterized in the sense by a particularly high practicality that even stringent requirements are met in terms of dust emissions without significantly compromising the economy and reliability of the sweeper and / or sacrificing reach with the need for increased unproductive empty runs compared to the prior art.
Gelöst wird die vorstehend angegebene Aufgabenstellung, indem eine Kehrmaschine der eingangs angegebenen Art einen der Umgebung der Kehrmaschine ausgesetzten, ein Niederschlagsignal generierenden, mit der Steuerung in signalübertragender Verbindung stehenden Niederschlagssensor aufweist, wobei die Steuerung das auf die Wasserpumpe bzw. das mindestens ein Wasserventil geschaltete Wassermengensteuersignal in Abhängigkeit von dem Niederschlagsignal erzeugt. Die erfindungsgemäße Kehrmaschine zeichnet sich somit, mit anderen Worten, dadurch aus, dass bei der Einstellung der durch das Wassersystem ausgebrachten Wassermenge, d. h. der Einstellung der Wasserpumpe bzw. des mindestens einen Wasserventils mittels der Steuerung, während des jeweiligen Kehreinsatzes fallende Niederschläge automatisch berücksichtigt werden. Die Erfindung baut somit auf der Erkenntnis auf, dass der Bedarf an Wasser, das zu verdüsen ist, um die angestrebte Staubbindung zu erzielen, sich in Abhängigkeit von (natürlichen) Niederschlägen ändert, wobei ein qualitativer Zusammenhang dahingehend besteht, dass die mittels des Wassersystems zu verdüsende Wassermenge mit steigender Niederschlagsintensität abnimmt. Insoweit generiert der Niederschlagssensor bevorzugt ein von der Niederschlagsintensität abhängiges, z. B. zu dieser mehr oder weniger proportionales Niederschlagsignal. In Anwendung der vorliegenden Erfindung lässt sich der mit der Kehrmaschine mitgeführte Wasservorrat substantiell besser nutzen als nach dem Stand der Technik. Der Verbrauch an Frischwasser ist dementsprechend reduziert, so dass - unter Reduzierung unproduktiver Leerfahrten auf das absolute Minimum - die Reichweite der Kehrmaschine maximiert bzw. deren Einsatzdauer optimiert wird.The above-mentioned problem is solved by a sweeper of the type specified has an environment of the sweeper, a precipitation signal generating, with the controller in signal-transmitting connection standing precipitation sensor, wherein the control on the water pump or the at least one water valve switched water quantity control signal generated in response to the precipitation signal. The sweeping machine according to the invention is thus characterized, in other words, by the fact that during the adjustment of the amount of water discharged by the water system, ie the setting of the water pump or of the at least one water valve by means of the control, precipitation falling during the respective sweeping operation is automatically taken into account. The invention thus builds on the recognition that the need for water to be atomized in order to achieve the desired dust binding changes depending on (natural) precipitation, with a qualitative connection being that by means of the water system decreasing amount of water decreases with increasing precipitation intensity. In that regard, the precipitation sensor preferably generates a dependent of the precipitation intensity, z. B. to this more or less proportional precipitation signal. In application of the present invention, the water supply carried by the sweeper can be used substantially better than in the prior art. The consumption of fresh water is correspondingly reduced, so that - while reducing unproductive empty runs to the absolute minimum - the range of the sweeper is maximized or its service life is optimized.
Gemäß einer ersten bevorzugten Weiterbildung der Erfindung handelt es sich bei dem Wassersystem um ein Frischwassersystem, wobei die Kehrmaschine weiterhin mit einem Schmutzwasser-Umlaufsystem ausgestattet ist. Namentlich kann dabei eine Kehrmaschine der eingangs genanten Art sowohl ein Umluftsystem mit einer sich vom Kehrgut-Sammelbehälter zum Saugkopf erstreckende Umluft-Rückführung und einer am Saugkopf angeordnete Umluftdüse als auch ein Schmutzwasser-Umlaufsystem umfassen, wobei letzteres einen am Kehrgut-Sammelbehälter angeordneten Wasserabscheider, einen hiermit kommunizierenden Schmutzwassertank, eine Schmutzwasserpumpe, und mindestens eine dem Kehrgut-Ansaugtrakt zugeordnete, in diesen Schmutzwasser einsprühende Schmutzwasserdüse aufweist. In synergetischem Zusammenwirken der beiden genannten Wassersysteme (Frischwassersystem und Schmutzwasser-Umlaufsystem) lassen sich hervorragende Staubemissionswerte erreichen, ohne dass dies mit den weiter oben dargelegten Nachteilen bekannter Kehrmaschinen verbunden wäre. Der mitgeführte Wasservorrat wird optimal genutzt. Der Verbrauch an Frischwasser ist minimal und kann sich idealerweise auf das Verdüsen von Frischwasser im Bereich des mindestens einen Besens beschränken. Für alle weiteren Verwendungen von Wasser zur Staubbindung kann (zirkulierend genutztes) Schmutzwasser eingesetzt werden. Da dieses aus dem in den Kehrgut-Sammelbehälter gelangenden Kehrgut abgeschieden wird, hat letzteres eine die Entsorgung nicht beeinträchtigende Konsistenz; und zudem werden - im Sinne einer hohen Reichweite - das Fassungsvermögen des Kehrgut-Sammelbehälters und die zulässige Zuladung der Kehrmaschine optimal genutzt. Durch die mehrfache Nutzung des (zirkulierenden) Schmutzwassers kann die in den Kehrgut-Ansaugtrakt eingedüste Menge - ohne Rücksicht auf den "Verbrauch" - im Hinblick auf die staubbindende Wirkung optimiert werden. Auch bei größeren in den Ansaugtrakt eingedüsten Mengen an Schmutzwasser ist zudem (im Winter) die Gefahr einer Vereisung gering; denn infolge der Luftzirkulation liegt die Temperatur der den Ansaugtrakt durchströmenden Luft über der Umgebungstemperatur. Der Austrag an Wasser aus dem System über die den Kehrgut-Sammelbehälter verlassende Abluft ist minimal, weil der Abluftstrom selbst minimiert ist. Er macht typischerweise nur einen Bruchteil (idealerweise zwischen etwa 15% und 25%) des durch den Kehrgut-Ansaugtrakt in den Kehrgut-Sammelbehälter eingesaugten Luftstromes aus; denn der überwiegende Anteil (idealerweise zwischen etwa 75% und 85%) des angesaugten Luftstromes zirkuliert über die Umluft-Rückführung, d.h. wird nach dem Verlassen der Umluftdüse wieder durch den Ansaugtrakt angesaugt. Mit der entsprechenden mengenmäßigen Reduktion des den Kehrgut-Sammelbehälter verlassenden, in die Umgebung abgegebenen Luftstromes geht auch ein entsprechend verringerter Austrag von Staub aus dem System einher. Die derart verringerte Abluftmenge erlaubt weiterhin den wirtschaftlichen Einsatz von (entsprechend kompakten) Abluft-Filtersystemen.According to a first preferred embodiment of the invention, the water system is a fresh water system, wherein the sweeper is further equipped with a dirty water circulation system. In particular, while a sweeper of the type mentioned both a recirculation system with a sweeping from the collecting container to the suction head recirculating air recirculation and disposed on the suction head Umluftdüse and a wastewater circulation system comprise, the latter arranged on a debris collection water separator, a Having hereby communicating dirty water tank, a dirty water pump, and at least one of the sweeping material intake tract associated, in this dirty water spraying dirty water nozzle. In synergetic interaction of the two water systems mentioned (fresh water system and wastewater circulation system) excellent dust emission values can be achieved without this being associated with the above-mentioned disadvantages of known sweeping machines. The entrained water supply is used optimally. The consumption of fresh water is minimal and can ideally be limited to the spraying of fresh water in the range of at least one broom. For all other uses of water for dust binding, (circulating) waste water can be used. Since this is separated from the reaching into the debris collecting container sweeping material, the latter has a disposal that does not affect the consistency; and also - in terms of a long range - the capacity of the debris collection container and the allowable payload of the sweeper optimally used. Through the multiple use of the (circulating) dirty water, the amount injected into the sweepings intake tract can be optimized with regard to the dust-binding effect, regardless of the "consumption". Even with larger injected into the intake system amounts of waste water is also (in winter), the risk of icing low; because as a result of the air circulation, the temperature of the intake air flowing through the air is above the ambient temperature. The discharge of water from the system via the exhaust air collecting the collecting waste container is minimal, because the exhaust air flow itself is minimized. It typically accounts for only a fraction (ideally between about 15% and 25%) of the airflow drawn into the debris hopper through the sweep intake manifold; because the predominant portion (ideally between about 75% and 85%) of the sucked air flow circulates through the circulating air recirculation, ie is sucked back into the intake tract after leaving the Umluftdüse. With the appropriate quantitative reduction of the sweeping material collecting container leaving, discharged into the environment air flow is accompanied by a correspondingly reduced discharge of dust from the system. The thus reduced amount of exhaust air continues to allow the economic use of (correspondingly compact) exhaust air filter systems.
Gemäß einer anderen bevorzugten Weiterbildung der Erfindung ist eine Anzeigeeinheit vorgesehen, welche einen vom jeweils aktuellen Wassermengensteuersignal abhängigen Wert optisch anzeigt. Insbesondere kann die Anzeigeinheit dabei einen Wert anzeigen, der dem Verhältnis zwischen dem aktuellen Wassermengensteuersignal und demjenigen entspricht, welches sich ohne eine Berücksichtigung des Niederschlagssignals (bzw. unter Berücksichtigung eines von dem Niederschlagsensor bei Abwesenheit jeglicher Niederschläge generierten Niederschlagsignals) ergäbe.According to another preferred embodiment of the invention, a display unit is provided which displays a value dependent on the respective current water quantity control signal value. In particular, the display unit may indicate a value that corresponds to the ratio between the current water quantity control signal and the one which would result without taking into account the precipitation signal (or taking into account a precipitation signal generated by the precipitation sensor in the absence of any precipitation).
Gemäß einer wiederum anderen bevorzugten Weiterbildung der Erfindung umfasst die Steuerung ein Wassermengensteuersignal-Grundmodul und ein diesem nachgeschaltetes Wassermengensteuersignal-Adaptionsmodul, wobei das Wassermengensteuersignal-Grundmodul einen von dem Niederschlagsignal unabhängigen Wassermengengrundwert generiert, welcher in dem Wassermengensignal-Adaptionsmodul in Abhängigkeit von dem Niederschlagssignal modifiziert wird. In diesem Falle entspricht der vorstehend erläuterte, von einer Anzeigeeinheit angezeigte Wert besonders bevorzugt dem Verhältnis zwischen dem aktuellen Wassermengensteuersignal und dem zugrundeliegenden, im Wassermengensteuersignal-Grundmodul generierten Wassermengengrundwert. Ein weiterer Vorteil einer solchen zweistufigen Generierung des Wassermengensteuersignals besteht darin, dass im Bedarfsfall - über eine geeignete, zusätzlich vorgesehene manuelle Bedieneinheit - manuell auf die Modifikation des im Wassermengensteuersignal-Grundmodul generierten Wassermengengrundwerts in dem Wassermengensteuersignal-Adaptionsmodul Einfluss genommen werden kann, bis hin zu einem vollständigen Außerfunktionsetzen der Berücksichtigung des Niederschlagsignals in dem Wassermengensteuersignal-Adaptionsmodul. So kann bedarfsweise selbst bei (natürlichen) Niederschlägen mit der "vollen" Wassermenge gearbeitet werden, beispielsweise wenn die Art des spezifischen Kehrguts dies als angeraten erscheinen lässt. Infolge dieser Möglichkeit der manuellen Einflussnahme kann umgekehrt die automatische, in dem Wassermengensteuersignal-Adaptionsmodul erfolgende "standardmäßige" niederschlagsabhängige Reduzierung der Wassermenge so weitreichend sein, dass sich massive Auswirkungen auf den Wasserverbrauch erreichen lassen. In diesem Sinne kann beispielsweise in dem Wassermengensteuersignal-Adaptionsmodul eine Reduzierung des (in dem Grundmodul generierten) Wassermengengrundwerts um 50% bei mittleren Niederschlägen und sogar um 100% bei starken Niederschlägen erfolgen.According to yet another preferred development of the invention, the controller comprises a water quantity control signal basic module and a water quantity control signal adaptation module connected thereto, wherein the water quantity control signal basic module generates a water quantity basic value which is independent of the precipitation signal and which is modified in the water quantity signal adaptation module as a function of the precipitation signal. In this case, the above-explained value displayed by a display unit particularly preferably corresponds to the ratio between the current water quantity control signal and the underlying water quantity basic value generated in the water quantity control signal basic module. Another advantage of such a two-stage generation of the water quantity control signal is that in case of need - via a suitable, additionally provided manual control unit - manually on the modification of the water quantity control signal basic module generated water quantity base value in the water quantity control signal adaptation module can be influenced up to a completely disregarding the consideration of the precipitation signal in the water quantity control signal adaptation module. Thus, if necessary, even with (natural) rainfall with the "full" amount of water can be worked, for example, if the type of specific debris appear advisable leaves. Conversely, as a result of this manual intervention possibility, the automatic "default" precipitation-dependent reduction of the amount of water in the water quantity control signal adaptation module can be so far-reaching that massive effects on water consumption can be achieved. In this sense, for example, in the water quantity control signal adaptation module, a reduction of the basic amount of water quantity (generated in the basic module) can occur by 50% with medium rainfall and even by 100% with heavy rainfall.
Im Folgenden wird die vorliegende Erfindung anhand in der Zeichnung veranschaulichter bevorzugter Ausführungsbeispiele näher erläutert.In the following, the present invention will be explained in more detail with reference to preferred embodiments illustrated in the drawing.
Die in der Zeichnung in zwei Varianten gezeigte selbstfahrende aufnehmende Kehrmaschine 1 umfasst, wie dies bereits für bekannte Kehrmaschinen gilt und deshalb nicht näher erläutert werden muss, ein Trägerfahrzeug 2, eine Kehreinheit 3 und eine Kehrgut-Aufnahmeeinheit 4. Die frontseitig am Trägerfahrzeug 2 angeordnete Kehreinheit 3 weist dabei mindestens einen durch einen Motor 5 rotierend angetriebenen Besen 6 auf; und die Kehrgut-Aufnahmeeinheit 4 umfasst einen Kehrgut-Ansaugtrakt 7 und einen Kehrgut-Sammelbehälter 8. Der Kehrgut-Sammelbehälter 8 weist seinerseits ein Sauggebläse 9 auf, und der Kehrgut-Ansaugtrakt 7 umfasst einen Saugkopf 10 und einem in den Kehrgut-Sammelbehälter 8 mündenden Saugkanal 11. Weiterhin weist die Kehrmaschine 1 ein Frischwassersystem 12 mit einem Frischwassertank 13, einer Frischwasserpumpe 14, einer Frischwasser-Leitungsanordnung 15 und mindestens einer durch diese gespeisten, dem mindestens Besen 6 zugeordneten Frischwasser-Sprühdüse 16 auf.The self-propelled pick-up sweeper 1 shown in the drawing in two variants comprises, as already applies to known sweepers and therefore need not be explained in more detail, a
Kennzeichnend für die Kehrmaschine gemäß den gezeigten Ausführungsbeispielen sind die beiden zusammenwirkenden, nachstehend näher erläuterten Zirkulationssysteme, nämlich ein Umluftsystem sowie ein Schmutzwasser-Umlaufsystem.Characteristic of the sweeper according to the embodiments shown are the two interacting, explained in more detail below circulation systems, namely a recirculation system and a dirty water circulation system.
Das Umluftsystem umfasst eine sich vom Kehrgut-Sammelbehälter 8 zum Saugkopf 10 erstreckende Umluft-Rückführung 17 (mehrteilig mit einem am Kehrgut-Sammelbehälter 8 fixierten Oberteil und einem von diesem trennbaren Unterteil) eine am Saugkopf 10 angeordnete Umluftdüse 18, aus der die Umluft (auf die Fahrtrichtung A bezogen) hinter der Aufnahmeöffnung 19 des Saugkopfes 10 und in der Fahrtrichtung A der Kehrmaschine gerichtet austritt. Die Umluft wird dabei aus der durch das Sauggebläse 9 geförderten Luft abgezweigt, zu welchem Zweck stromabwärts des Sauggebläses 9 eine Abluftverzweigung 20 mit einem an einer (oben am Kehrgut-Sammelbehälter 8 angeordneten, mit einem Feinfilter 21 ausgestatteten) Abluftöffnung 22 mündenden ersten Luftströmungsweg 23 und einem der Umluft-Rückführung 17 zugeordneten zweiten Luftströmungsweg 24 vorgesehen ist. Das - als Radialgebläse ausgeführte - Sauggebläse 9 ist frontseitig in dem Kehrgut-Sammelbehälter 8 oberhalb des Saugkanals 11 angeordnet, und zwar mit einer dergestalt geneigten Achse X. Bei der Variante nach
Das Schmutzwasser-Umlaufsystem 34 umfasst einen - seitlich neben dem Frischwassertank 13 angeordneten - Schmutzwassertank 25, eine Schmutzwasserpumpe 26, eine Schmutzwasser-Leitungsanordnung 27 und mehrere Schmutzwasserdüsen 28. Die (Schmutzwasser in den Kehrgut-Ansaugtrakt 7 einsprühenden) Schmutzwasserdüsen 28 sind auf unterschiedlichen Höhen, d.h. unterschiedlich weit von der Aufnahmeöffnung 19 des Saugkopfes 10 entfernt angeordnet. Weiterhin umfasst das Schmutzwasser-Umlaufsystem einen am Kehrgut-Sammelbehälter 8 angeordneten Wasserabscheider 29. Das mit diesem aus dem Kehrgut abgeschiedene Schmutzwasser gelangt zurück in den Schmutzwassertank 25.The dirty
Die Kehrmaschine 1 ist weiterhin mit einer sog. Handsaugeinrichtung 30 ausgestattet. Diese umfasst ein manuell zu bedienendes Saugrohr 31 und einen in den Kehrgut-Sammelbehälter 8 mündenden Schlauch 32. An der Mündung des Saugrohres der Handsaugeinrichtung ist eine - aus dem Frischwassertank 13 gespeiste - Wasserdüse 33 (vgl.
Die Kehrmaschine weist eine eine Steuereinheit 35 umfassende Steuerung S auf. Diese steuert bzw. regelt die Antriebsmotoren 5 für die Besen 6, d. h. insbesondere deren Drehzahl, den Antriebsmotor 36 des Sauggebläses 9, d. h. dessen Drehzahl, die Frischwasserpumpe 14, d. h. deren Förderleistung, und die Schmutzwasserpumpe 26, d. h. deren Förderleistung. Die Steuereinheit 35 berücksichtigt dabei für die besagten Steuerfunktionen - in als solches bekannter Weise - verschiedene Eingangsgrößen. Eine wesentliche von diesen stellt die Fahrgeschwindigkeit der Kehrmaschine dar, weshalb beispielhaft ein mit der Steuereinheit 35 signalübertragend verbundener Tachometer 37 gezeigt ist.The sweeper has a controller S comprehensive control S on. This controls or regulates the
Weiterhin steht mit der Steuereinheit 35 ein Niederschlagssensor 38 in signalübertragender Verbindung, der der Umgebung der Kehrmaschine ausgesetzt ist und ein für die Intensität eines Niederschlags 39 repräsentatives Niederschlagssignal generiert. Dieses ist über die Signalleitung 40 auf ein Wassermengensteuersignal-Adaptionsmodul 41 geschaltet, das Teil der Steuerung S und einem - von der Steuereinheit 35 umfassten - Wassermengensteuersignal-Grundmodul 42 nachgeschaltet ist. Im Zusammenwirken miteinander regeln das Wassermengensteuersignal-Grundmodul 42 und das diesem nachgeschaltete Wassermengensteuersignal-Adaptionsmodul 41 die Förderleistung der Frischwasserpumpe 14 dergestalt, dass das Wassermengensteuersignal-Grundmodul 42 zunächst einen von dem Niederschlagsignal unabhängigen Wassermengengrundwert generiert, welcher in dem Wassermengensteuersignal-Adaptionsmodul 41 in Abhängigkeit von dem Niederschlagssignal zum tatsächlichen, niederschlagsabhängigen Einstellwert für die Frischwasserpumpe 14 modifiziert wird.Furthermore, with the
Entsprechendes gilt für abgewandelte System, bei denen die in den Frischwasserdüsen 16 verdüste Wassermenge nicht über die Versstellung der Frischwasserpumpe 14 eingestellt wird, sondern mittels Frischwasserventilen.The same applies to modified system in which the amount of water in the
Eine in dem Führerhaus der Kehrmaschine vorgesehene Anzeigeeinheit 43 zeigt dem Maschinenführer einen vom jeweils aktuellen Wassermengensteuersignal abhängigen Wert, beispielsweise das Verhältnis zwischen dem aktuellen Wassermengensteuersignal und dem im Wassermengensteuersignal-Grundmodul 42 generierten Wassermengengrundwert optisch an. Mittels der weiterhin im Führerhaus vorgesehenen manuellen Bedieneinheit 44 lässt sich die Funktionsweise des Wassermengensteuersignal-Adaptionsmoduls 41 manuell beeinflussen.A
