Abstract
Description
Die Erfindung betrifft eine Saugvorrichtung für ein Flächenreinigungsfahrzeug gemäß den Merkmalen im Oberbegriff von Schutzanspruch 1.The invention relates to a suction device for a surface cleaning vehicle according to the characteristics in the preamble of protection claim 1.
Zur Säuberung von Straßen, Plätzen, Freiflächen usw. kommen Flächenreinigungsfahrzeuge wie Straßenkehrmaschinen mit Walzenbürsten oder Kehrichtsauganlagen zum Einsatz.For cleaning streets, squares, open spaces, etc. come surface cleaning vehicles like street sweepers with roller brushes or garbage suction systems for use.
Durch die
Aus der DE-AS 1 092 498 ist eine selbstaufnehmende Kehrmaschine bekannt, bei der die Saugvorrichtung im mittleren Bereich des Fahrzeugs zwischen den Fahrzeugachsen angeordnet ist. Die Flächenreinigung erfolgt über einen Walzenbesen, der von einer Haube überdeckt ist, die an der Außenseite mit dem Saugkanal versehen ist. An dem der zu reinigenden Fläche zugewandten Saugmund des Saugtrichters ist an einer quer zur Fahrtrichtung des Flächenreinigungsfahrzeugs ausgerichteten Längsseite eine Luftleitfläche vorgesehen.From DE-AS 1 092 498 is one self-picking sweeper known in which the suction device arranged in the middle of the vehicle between the vehicle axles is. The surface cleaning takes place via a roller broom, which is covered by a hood that with the outside the suction channel is provided. On the surface facing the surface to be cleaned The suction mouth of the suction funnel is at a cross to the direction of travel of the A surface cleaning vehicle aligned long side one air duct intended.
Bekannt sind auch Saugsysteme, bei dem das Kehrgut nicht nur durch Unterdruck des Sauggebläses sondern auch durch die Impulskraft des Abluftstrahls vom Boden abgehoben und in den Sammelbehälter überführt werden soll.Suction systems are also known at which the debris not only by vacuum of the suction fan but also lifted off the floor by the impulsive force of the exhaust air jet and transferred to the collection container should.
Der Erfindung liegt ausgehend vom Stand der Technik die Aufgabe zugrunde, eine Saugvorrichtung für ein Flächenreinigungsfahrzeug anwendungstechnisch zu verbessern, so dass der Reinigungseffekt gesteigert werden kann.The invention is based on The prior art is based on the task of a suction device for a surface cleaning vehicle improve application technology, so that the cleaning effect can be increased.
Die Lösung dieser Aufgabe besteht nach der Erfindung in einer Saugvorrichtung für ein Flächenreinigungsfahrzeug gemäß den Merkmalen von Schutzanspruch 1.The solution to this problem exists according to the invention in a suction device for a surface cleaning vehicle according to the features of protection claim 1.
Kernpunkt der Erfindung bildet die Maßnahme, dass zumindest an einer quer zur Fahrrichtung des Flächenreinigungsfahrzeugs ausgerichteten Längsseite des Saugmundes eine Luftleitfläche vorgesehen ist, welche eine vom Saugmund ausgehend zu der zu reinigenden Fläche hin konvex gekrümmt verlaufende Kontur besitzt. Die Luftleitfläche definiert einen Saugspalt mit geringem Querschnitt und bewirkt aufgrund ihrer Kontur, dass sich der eintretende Fluid- bzw. Saugstrom an ihrer Oberfläche anlegt und entsprechend der Krümmung seine Richtung in den Saugmund ändert. Der eintretende Saugstrom wird der Kontur der Luftleitfläche folgend um diese herum gezogen. Hierdurch wird eine Impulsverstärkung des Saugstroms erreicht und der Saugeffekt erhöht.The crux of the invention is the Measure, that at least on one transverse to the direction of travel of the surface cleaning vehicle aligned long side an air guide surface of the suction mouth It is provided, which starts from the suction mouth to the one to be cleaned area towards convexly curved Has contour. The air control surface defines a suction gap with a small cross-section and causes due to its contour that the incoming fluid or suction flow is applied to its surface and according to the curvature changes its direction in the suction mouth. The incoming suction flow follows the contour of the air guide surface drawn around this. As a result, a pulse amplification of the suction flow reached and the suction effect increased.
Sowohl an der vorderen Längsseite als auch an der hinteren Längsseite des Saugmunds sind Luftleitflächen vorgesehen, wodurch der Saug- und Reinigungseffekt besonders wirksam gesteigert werden kann.Both on the front long side as well as on the rear long side of the suction mouth are air guiding surfaces provided, making the suction and cleaning effect particularly effective can be increased.
Die Luftleitflächen bestehen aus einem elastisch nachgiebigen Material. Hierdurch können Beschädigungen der Luftleitflächen, beispielsweise durch Einklemmen von Gesteinsbrocken und ähnlichem, vermieden und der Verschleiß gesenkt werden.The air guiding surfaces consist of an elastic compliant material. This can damage the air guide surfaces, for example, by Pinching boulders and the like, avoided and the Wear reduced become.
Praktische Versuche haben einen deutlich höheren Reinigungseffekt gezeigt. Selbst anhaftende oder feuchte Verschmutzungen werden zuverlässig abgesaugt. Insbesondere bei Flächenreinigungsfahrzeugen mit Hochdruckwascheinrichtungen konnte bei Einsatz der erfindungsgemäßen Saugvorrichtung ein hoher Reinigungseffekt mit porentiefer Flächenreinigung erzielt werden, wobei die gereinigten Flächen nach dem Absaugvorgang im Vergleich zur konventionellen Absaugung wesentlich trockener sind.Practical tests have a significantly higher cleaning effect shown. Even adhering or damp dirt is reliably vacuumed off. Especially for surface cleaning vehicles with high pressure washers could use the suction device according to the invention high cleaning effect can be achieved with deep pore cleaning, being the cleaned surfaces after the suction process compared to conventional suction are much drier.
Vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Saugvorrichtung sind in den abhängigen Schutzansprüchen 2 bis 4 charakterisiert. Schutzanspruch 5 zielt auf ein Flächenreinigungsfahrzeug mit der Saugvorrichtung ab.Advantageous configurations and Further developments of the suction device according to the invention are shown in the dependent protection claims 2 to 4 characterized. Protection claim 5 is aimed at a surface cleaning vehicle with the suction device.
Für die Praxis bietet es sich an, die Luftleitfläche durch einen parallel zur Längsseite des Saugtrichters ausgerichteten Rohrkörper auszubilden. Diese Ausführungsform ist konstruktiv vorteilhaft und stabil. Sie ermöglicht auch eine Nach- bzw. Umrüstung konventioneller Saugvorrichtungen. Die Rohrkörper bestehen aus Kunststoff und sind mittels geeigneter Halterungen am Saugtrichter festgelegt.For in practice it is advisable to use a parallel to the air control surface long side the aligned tube body to form the suction funnel. This embodiment is structurally advantageous and stable. It also enables a subsequent or conversion conventional suction devices. The tubular body is made of plastic and are attached to the suction funnel using suitable brackets.
Es können auch an den Querseiten des Saugmunds Luftleitflächen angeordnet sein, womit der an sich rechteckförmig konfigurierte Saugmund eine trompetenartig gestaltete Ansaugzone erhält. Die Anordnung von Luftleitflächen an den Querseiten des Saugmunds verbessert die seitliche Aufnahme von Kehrricht. Dies ist insbesondere dann vorteilhaft, wenn sich Kehricht vor dem Saugtrichter staut und seitlich um diesen herum geschoben wird.It can also be on the short sides of the suction mouth be arranged, with which the suction mouth configured in a rectangular manner is a trumpet-like intake zone. The arrangement of air control surfaces the transverse sides of the suction mouth improve the lateral intake of sweeping. This is particularly advantageous if rubbish is in front of the Suction funnel jams and is pushed sideways around it.
Die Luftleitflächen können am Saugtrichter nachgiebig angelenkt sein, so dass sie etwaigen Hindernissen ausweichen können.The air guiding surfaces can be flexible on the suction funnel be articulated so that they can avoid any obstacles.
Wie bereits oben erwähnt, wird eine besonders wirksame Flächenreinigung erzielt mit einer Saugvorrichtung, die mit einer Hochdruckwascheinheit zusammenwirkt. Hierbei kommt insbesondere eine hintere Absaugung mit Hochdruckwascheinrichtung über die gesamte Fahrzeugbreite zum Einsatz.As already mentioned above, a particularly effective surface cleaning achieved with a suction device that with a high pressure washing unit interacts. Here, in particular, there is a rear suction with high pressure washer over the entire vehicle width is used.
