Der Erfindung liegt nun die Aufgabe zugrunde, einen anderen Lösungsweg zu finden, um eine gleichförmige Streugutverteilung über die gewünschte Streubreite zu erzielen.The invention is based on the object to find another approach to achieve a uniform spreading material distribution over the desired spread.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruches 1 gelöst.According to the invention, this object is solved by the features of
Der erfindungsgemäße Streuteller für ein Winterdienst-Streugerät weist eine Streutelleroberfläche aufweist, die um eine Drehachse rotierend antreibbar ist und sieht auf der Streutelleroberfläche radial verlaufende Wurfschaufeln vor, die den Streuteller zwischen sich in Segmente unterteilen, wobei zumindest bei einigen, vorzugsweise bei allen benachbarten Segmenten zumindest ein Teil der Streutelleroberfläche mit unterschiedlichen Neigungen gegenüber der Drehachse ausgebildet ist.The spreading plate according to the invention for a winter service spreader has a spreading plate surface which is driven to rotate about a rotation axis and provides on the scattering plate surface radially extending throwing blades, which divide the spreading plate between them into segments, wherein at least some, preferably all the adjacent segments at least part of the spreading plate surface is formed with different inclinations relative to the axis of rotation.
Die unterschiedlich geneigten Segmente bewirken entsprechend unterschiedliche Wurfweiten, die sich zu einem sehr gleichförmigen Streubild ergänzen.The differently inclined segments cause correspondingly different casting distances, which complement each other to a very uniform scattering pattern.
Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further embodiments of the invention are the subject of the dependent claims.
In einer bevorzugten Ausgestaltung der Erfindung weisen einige, vorzugsweise alle benachbarten Segmente unterschiedliche Größen auf.In a preferred embodiment of the invention, some, preferably all adjacent segments have different sizes.
Die Neigungswinkel der Segmente, mit denen zumindest die radial äußeren Bereiche der Streutelleroberflächen benachbarter Segmente gegenüber einer Senkrechten zur Drehachse geneigt sind, liegen im Bereich von 0° < β ≤ 30°, vorzugsweise 0° < β ≤ 20°.The angles of inclination of the segments, with which at least the radially outer regions of the scattering plate surfaces of adjacent segments are inclined with respect to a perpendicular to the axis of rotation, are in the range of 0 ° <β ≦ 30 °, preferably 0 ° <β ≦ 20 °.
Weiterhin sind wenigstens 50%, vorzugsweise 80 bis 100% der radialen Erstreckung der Streutelleroberfläche der Segmente gegenüber einem inneren Bereich des Streutellers geneigt ausgebildet. Die Neigung wird dabei beispielsweise durch Aufkantung der Streutelleroberfläche gegenüber einem inneren Bereich des Streutellers erreicht. Die Wurfschaufeln sind bogenförmig oder geradlinig ausgebildet.Furthermore, at least 50%, preferably 80 to 100%, of the radial extent of the spreading plate surface of the segments is inclined relative to an inner region of the spreading plate. The inclination is achieved for example by Aufkantung the scattering plate surface relative to an inner region of the spreading plate. The throwing blades are arc-shaped or rectilinear.
Gemäß einer bevorzugten Ausgestaltung ist der Streuteller in seiner Draufsicht kreisförmig ausgebildet und die radial innen liegenden Enden der Wurfschaufeln sind mit gleichem radialen Abstand zur Drehachse angeordnet. Auch die radial außen liegenden Enden der Wurfschaufeln weisen vorzugsweise den gleichen radialen Abstand zur Drehachse auf.According to a preferred embodiment of the scattering plate is circular in plan view and the radially inner ends of the throwing blades are arranged at the same radial distance from the axis of rotation. The radially outer ends of the throwing vanes preferably have the same radial distance from the axis of rotation.
Die Anordnung der unterschiedlich geneigten Segmente in Umfangsrichtung des Streutellers ist auf unterschiedliche Arten denkbar. So kann der Streuteller beispielsweise in mehrere Gruppen mit jeweils wenigstens zwei, vorzugsweise drei bis fünf Wurfschaufeln unterteilt sein, die jeweils gleich aufgebaut sind, wobei sich innerhalb einer Gruppe die Neigung der Streutelleroberfläche benachbarter Segmente kontinuierlich vergrößert oder verkleinert. Es wäre aber auch denkbar, dass - in Umfangsrichtung des Streutellers gesehen - die Neigung der Streutelleroberfläche benachbarter Segmente abwechselnd größer und kleiner als die vorhergehende Neigung ausgebildet ist.The arrangement of the differently inclined segments in the circumferential direction of the spreading plate is conceivable in different ways. For example, the scattering plate may be subdivided into a plurality of groups, each having at least two, preferably three to five, throwing blades which are each constructed the same, wherein within a group the inclination of the spreading plate surface of adjacent segments increases or decreases continuously. But it would also be conceivable that - seen in the circumferential direction of the spreading plate - the inclination of the spreading plate surface of adjacent segments is alternately larger and smaller than the previous inclination is formed.
Weiterhin betrifft die Erfindung einen Streuautomat mit einem Streuteller gemäß der oben beschriebenen Art, wenigstens einem Vorratsbehälter für Streugut sowie einer Zuführeinrichtung, um das Streugut vom Vorratsbehälter dem Streuteller zuzuführen.Furthermore, the invention relates to a spreader with a spreading plate according to the type described above, at least one storage container for grit and a feeder to supply the grit from the reservoir to the spreading plate.
Außerdem umfasst die Erfindung ein Winterdienst-Streugerät mit einem derartigen Streuautomat.In addition, the invention comprises a winter service spreader with such a spreader.
Weitere Ausgestaltungen und Vorteile der Erfindung werden im Folgenden anhand der Beschreibung und der Zeichnung näher erläutert.Further embodiments and advantages of the invention are explained in more detail below with reference to the description and the drawing.

Zumindest die radial äußeren Bereiche 5a der Streutelleroberfläche benachbarter Segmente weisen unterschiedlichen Neigungen auf. Die Neigungswinkel der Streutelleroberflächen gegenüber einer Senkrechten zur Drehachse, liegen im Bereich von 0° < β ≤ 30°, vorzugsweise 0° < β ≤ 20°. Im dargestellten Ausführungsbeispiel sind die radial äußeren Bereiche 5a der Streutelleroberflächen gegenüber einem inneren Bereich 10 des Streutellers um die Winkel β1, β2, β3 bzw. β4 aufgekantet, wobei β1 < β2 < β3 < β4.At least the radially
Die Wurfschaufeln 8 sind hier geradlinig ausgebildet und mit den radial innen liegenden Enden mit gleichem radialen Abstand von der Drehachse 7 angeordnet. Auch die radial außen liegenden Enden der Wurfschaufeln 8 sind mit gleichem radialen Abstand zur Drehachse angeordnet, sodass der Streuteller in der Draufsicht kreisförmig ausgebildet ist.The
Im dargestellten Ausführungsbeispiel weisen die Segmente 9, d.h. der Bereich des Streutellers zwischen den Wurfschaufeln 8, einen radial inneren Bereich 10 auf, der im Wesentlichen quer zur Drehachse 7 ausgebildet ist und einen aufgekanteten Bereich. Wenigstens 50%, vorzugsweise 80 bis 100% der radialen Erstreckung der Segmente sollte gegenüber dem sich quer zur Drehachse erstreckenden inneren Bereich 10 geneigt ausgebildet sein.In the illustrated embodiment, the segments 9, ie the area of the spreading plate between the
Zur Erzielung einer möglichst gleichmäßigen Streugutverteilung über die Streubreite sind benachbarte Segmente mit unterschiedlichen Neigungen ausgebildet.To achieve the most uniform spreading material distribution over the spreading width adjacent segments are formed with different inclinations.
Der Streuteller kann dabei in mehreren Gruppen von jeweils wenigstens 2, vorzugsweise 3 bis 5 Wurfschaufeln mit zugehörigen Segmenten unterteilt sein.The scattering plate can be divided into several groups of at least 2, preferably 3 to 5 throwing blades with associated segments.
Im Ausführungsbeispiel gemäß
Anstatt innerhalb einer Gruppe den Aufkantungswinkel in Umfangsrichtung immer größer werden zu lassen, wäre es aber auch denkbar, abwechselnd den Winkel zu vergrößern und dann wieder zu verkleinern. So könnte in Umfangsrichtung 11 beispielsweise zunächst ein Segment mit dem Aufkantungswinkel β1, dann ein Segment mit dem Aufkantungswinkel β3, anschließend ein Segment mit dem Aufkantungswinkel β2 und schließlich ein Segment mit dem Aufkantungswinkel β4 angeordnet werden. Die beiden darauf folgenden Gruppen mit jeweils vier Segmenten könnten dann wieder in der gleichen Art und Weise aufgebaut werden. Durch die unterschiedlichen Neigungen der Streutelleroberflächen benachbarter Segmente ergeben sich für das dort befindliche Streugut unterschiedliche Radialbeschleunigungen am Ende des Streutellers, wodurch unterschiedliche Wurfweiten erzielt werden.Instead, within a group, the Aufkantungswinkel in the circumferential direction are getting bigger, but it would also be conceivable to alternately increase the angle and then reduce it again. Thus, in the
Bei den der Erfindung zugrunde liegenden Versuchen hat sich gezeigt, dass mit einem derartigen Streuteller eine hervorragende Streugutverteilung über die Streubreite erreicht werden kann. Damit das Streugut die Wurfschaufeln erst an deren radial äußeren Enden verlässt, können die Wurfschaufeln 8 in ihrem oberen Bereich schaufelartig umgebogen sein, wie das aus der Zeichnung hervorgeht.In the experiments on which the invention is based, it has been shown that with such a spreading plate, an excellent spreading material distribution over the spreading width can be achieved. So that the grit leaves the throwing blades only at the radially outer ends, the
In
Während die einzelnen Segmente beim ersten Ausführungsbeispiel gleichgroß ausgebildet wurden, weisen die Segmente einer Gruppe beim Ausführungsbeispiel gemäß
Neben der unterschiedlichen Segmentgröße sind auch hier zumindest bei einigen, vorzugsweise bei allen benachbarten Segmenten ein Teil der Streutelleroberfläche mit unterschiedlichen Neigungen gegenüber der Drehachse ausgebildet.In addition to the different segment size, a part of the spreading plate surface with different inclinations with respect to the axis of rotation are also formed here at least in some, preferably in all adjacent segments.
Bei den der Erfindung zugrunde liegende Versuchen hat es sich als vorteilhaft erwiesen, wenn die Größe des Segments mit der Stärke der Neigung so korrespondiert, dass das kleinste Segment 9'a die kleinste Neigung (beispielsweise gemäß
Bei einer solchen Ausgestaltung ergibt sich das in
Anhand des Streubildes lässt es sich erkennen, dass der Winkel der Aufkantung und die Größe des Segmentes einen unmittelbaren Einfluss auf die erzielbare Streubreite B haben. Bei einem stärker aufgekanteten Segment verzögert sich der Austrag des Streugutes, sodass dieses eine stärkere Zentrifugalkraft erfährt und dadurch dann weiter ausgeworfen werden kann. Durch eine gezielte Abstimmung von Segmentgröße und Neigungswinkel der Streutelleroberflächen benachbarte Segmente kann eine gezielte Streubreite eingestellt und dabei ein gleichmäßiges Streubild erzielt werden.On the basis of the scattering pattern, it can be seen that the angle of the upstand and the size of the segment have a direct influence on the achievable spread B. With a more upturned segment, the discharge of the scattering material is delayed, so that it experiences a stronger centrifugal force and thus can be further ejected. By a specific vote of segment size and angle of inclination of the spreading plate surfaces adjacent segments can be set a targeted spread and thereby a uniform spreading pattern can be achieved.
Für unterschiedliche Streubreiten können daher zweckmäßigerweise unterschiedliche Streuteller vorgesehen werden.Therefore, for different spreading widths, it is expedient to provide different spreading discs.
