Die Erfindung bezieht sich auf eine Saug- und Blasmundstückvorrichtung, insbesondere zumStraßenreinigen, die dazu bestimmt ist, im Abstand über die zu reinigende Fläche bewegt zu werden und die ein Saugmundstück mit einer nach unten gerichteten Mündung in der Gestalt eines langgestreckten Schlitzes sowie ein das Saugmundstück mit nach oben geschlossenem Zwischenraum ringförmig umgebendes, in allen seinen Teilen schräg nach unten und innen gerichtetes Blasmundstück mit Länge der Mündung des Saugmundstückes verlaufenden geraden Schlitzteilen und diese verbindenden bogenförmigen Schlitzteilen aufweist, so daß von der ausströmenden Blasluft ein ringförmiger Schleier gebildet wird.The invention relates to a suction and blow mouthpiece device, in particular for street cleaning, which is intended to be moved at a distance over the surface to be cleaned and the one Suction mouthpiece with a downwardly directed mouth in the shape of an elongated slot as well as a ring-shaped surrounding the suction mouthpiece with a gap closed at the top, all parts of the mouthpiece are directed obliquely downwards and inwards with the length of the mouth of the suction mouthpiece extending straight slot parts and these connecting arcuate slot parts has, so that an annular veil is formed by the blown air flowing out.
Da allgemein die Saugwirkung mit größer werdendem Abstand des Saugmundstückes von der zu reinigenden Fläche sehr rasch abnimmt, ist es zweckmäßig, derartige Vorrichtungen mit möglichst geringem Abstand über die zu reinigende Fläche zu bewegen. Normalerweise kann aber dieser Abstand infolge vorhandener Unebenheiten auf der zu reinigenden Fläche nicht so klein gehalten werden, wie es wünschenswert ist. Er muß vielmehr so groß sein, daß die Vorrichtung nicht durch Anstoßen an solche Unebenheiten od. dgl. beschädigt wird. Je weiter nun die Vorrichtung von der zu reinigenden Oberfläche entfernt wird, um so kräftiger muß auch das die Luft fördernde Gebläse bemessen werden, damit die zu einer wirksamen Reinigung etwa einer Straßenoberfläche erforderliche Saug- und Blaswirkung erzielt wird. Aus praktischen Gründen kann jedoch die Leistung des Gebläses nicht beliebig gesteigert werden, so daß ein anderer Weg zur Lösung des Problems gefunden werden muß.Since, in general, the suction effect with increasing distance of the suction nozzle from the to cleaning area decreases very quickly, it is advisable to use such devices with as little as possible To move distance over the surface to be cleaned. Normally, however, this distance can due to existing bumps on the surface to be cleaned are not kept as small as it is is desirable. Rather, it must be so large that the device does not come into contact with such Unevenness or the like. Is damaged. The further the device is from the surface to be cleaned is removed, the more powerful the air-conveying fan must be dimensioned so that the to an effective cleaning about a road surface required suction and blowing effect achieved will. For practical reasons, however, the performance of the blower cannot be increased at will, so another way of solving the problem must be found.
Der jeweils erforderliche Abstand zwischen Vorrichtungen und zu reinigender Fläche hat außerdem noch eine andere nachteilige Erscheinung zur Folge, daß nämlich Überschußluft in unerwünschtem Maße Zutritt zum Saugmundstück finden kann. Hierdurch ist aber eine wirksame Staubabscheidung in Frage gestellt, wenn der Staubabscheider nicht übergroße Abmessungen erhalten soll oder sonstige zusätzliche Vorkehrungen getroffen werden. Für ein einwandfreies Arbeiten ist es daher wesentlich, die durch das Saugmundstück eingesaugte Luft soweit wie möglich auf diejenige Luft zu beschränken, welche durch das Blasmundstück ausgeblasen wird, d. h. die Menge der Uberschußluft, welche von außen her zum Saugmundstück zu strömen bestrebt ist, muß sehr gering gehalten werden.The required distance between devices and the surface to be cleaned also has yet another disadvantageous phenomenon, namely that excess air is undesirable Can find access to the suction mouthpiece. However, this calls into question an effective dust separation, if the dust separator should not have oversized dimensions or other additional dimensions Precautions are taken. In order to work properly, it is therefore essential that the Suction mouthpiece to restrict the air sucked in as far as possible to the air that passes through the Blow mouthpiece is blown out, d. H. the amount of excess air coming from the outside to the suction nozzle tends to flow must be kept very low.
Durch die Erfindung sollen nun die vorstehend genannten Probleme gelöst werden, d. h., es soll trotz Saug- und Blasmundstückvorrichtung, insbesondere zum StraßenreinigenThe invention is now intended to provide the aforementioned Problems are resolved, d. i.e., despite the suction and blow mouthpiece device, especially for street cleaning

eines notwendigerweise einzuhaltenden Abstandes zwischen Saug- und Blasmundstückvorrichtung und der zu reinigenden Oberfläche eine wirksame Reinigung ermöglicht werden, ohne daß dabei die Dimensionierung des zu verwendenden Gebläses Schwierigkeiten bereitet und ohne daß nachteilige Einflüsse durch Überschußluft auftreten.a necessary distance to be maintained between the suction and blow mouthpiece device and the surface to be cleaned can be effectively cleaned without the dimensioning being affected of the fan to be used presents difficulties and without adverse effects occur due to excess air.
Gemäß der Erfindung ist zur Erreichung dieses Zieles bei einer Vorrichtung der eingangs genannten Art vorgesehen, daß sich die Begrenzung des nach oben geschlossenen ringförmigen Zwischenraumes zwischen den unteren Rändern des Saugmundstückes und des Blasmundstückes nach oben wölbt und daß ferner die bogenförmigen Schlitzteile des Blasmundstückes mit einer geringeren Breite ausgebildet sind als seine geraden Schlitzteile.According to the invention, in order to achieve this aim, the device mentioned at the beginning is used Kind provided that the delimitation of the upwardly closed annular space between the lower edges of the suction mouthpiece and the blowing mouthpiece bulges upwards and that furthermore, the arcuate slot parts of the blow mouthpiece are formed with a smaller width than its straight slot parts.
Zweckmäßig sind die Seitenteile der Wölbung über dem ringförmigen Zwischenraum von zwei nach außen geneigten Wänden gebildet, von denen die äußere Wand steiler nach innen geneigt ist als die innere Wand, wobei dann der obere Teil der Wölbung aus einer gleichmäßig in die Wände übergehenden Rundung besteht.Appropriately, the side parts of the arch over the annular space from two to formed outwardly inclined walls, of which the outer wall is steeper inwardly inclined than the inner wall, with the upper part of the bulge then merging evenly into the walls Rounding exists.
Die äußere Wand kann zugleich die innere Wand des ringförmigen Blasmundstückes bilden.The outer wall can at the same time form the inner wall of the annular blow mouthpiece.
Bei der erfindungsgemäßen Vorrichtung erfährt die aus dem Blasmundstück ausgepreßte Luft in dem Zwischenraum eine Wirbelbewegung, welche am treffendsten als eine umlaufende Luftbürste bezeichnetIn the device according to the invention, the air pressed out of the blow mouthpiece experiences in the In between a vortex movement, which is most aptly referred to as a rotating air brush
