Description
Die Erfindung betrifft einen Schleuderstreuer gemäß des Oberbegriffes des Patentanspruches 1.The invention relates to a centrifugal spreader according to the preamble of
Ein derartiger Schleuderstreuer ist beispielsweise in der

Durch die
Der Erfindung liegt die Aufgabe zugrunde, eine einfach ausgestaltete Rührvorrichtung mit einer gut wirksamen Rührwirkung, insbesondere auch bei schlecht fließenden Materialien, um beispielsweise pulverförmigen Dünger, Split oder Sand in einem ausreichend fließfähigen Zustand zu bringen, zu schaffen.The invention has for its object to provide a simply configured stirring device with a well-acting stirring, especially in poorly flowing materials, for example, to bring powdered fertilizer, split or sand in a sufficiently flowable state.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Rührfinger aus einem elastischen Gummi- und/oder Kunststoffmaterial bestehen, dass die Rührfinger zumindest in ihrer radial äußeren Hälfte entgegen der Drehrichtung der Rührvorrichtung abgebogen sind, dass in jeder der axial zueinander beabstandeten Ebenen nur ein in einer radialen Richtung sich erstreckender Rührfinger angeordnet ist, dass die in den axial zueinander beabstandeten Ebenen angeordneten Rührfinger in Drehrichtung versetzt zueinander angeordnet sind.This object is achieved in that the stirring fingers are made of an elastic rubber and / or plastic material, that the stirring fingers are bent at least in its radially outer half against the direction of rotation of the stirring device that in each of the axially spaced planes only one in one Radial direction extending stirring finger is arranged so that the arranged in the axially spaced-apart planes Rührfinger are offset in the direction of rotation to each other.
Infolge dieser Maßnahmen ergibt sich eine einfach aufgebaute Rührvorrichtung. Beim Anlaufen der Rührvorrichtung können die aus einem elastischen Gummi- oder Kunststoffmaterial bestehenden Rührfinger entgegen der Drehrichtung ausweichen. Durch dieses Ausweichen der Rührfinger wird das Anlaufen erleichtert. Durch die Ausgestaltung der Rührfinger aus einem elastischen Gummi- oder Kunststoffmaterial können die Rührfinger, wenn sie die Vorratsbehälterwand berühren, diese nicht beschädigen. Durch das Berühren der Vorratsbehälterwand durch die Rührfinger ist sichergestellt, dass auch in den Ecken des Vorratsbehälters das sich im Vorratsbehälter befindliche und auszubringende Material in jedem Falle ausreichend aufgerührt wird, so dass nur geringe Restmengen von Material in dem Vorratsbehälter verbleiben. Durch die erfindungsgemäße Anordnung nur eines Rührfingers in jeder Ebene und durch die versetzte Anordnung der Rührfinger zueinander lässt sich mit einer geringstmöglichen Anzahl von Rührfinger eine maximale Rührwirkung der Rührvorrichtung erzielen.As a result of these measures results in a simply constructed stirring device. When the stirrer starts up, the agitating fingers made of an elastic rubber or plastic material can escape counter to the direction of rotation. Dodging the agitator fingers makes starting easier. Due to the design of the stirring fingers of an elastic rubber or plastic material, the stirring fingers when they touch the reservoir wall, they do not damage. By touching the reservoir wall by the agitator fingers ensures that even in the corners of the reservoir which is located in the reservoir and auszubringende material in each case is sufficiently stirred, so that only small residual amounts of material remain in the reservoir. The inventive arrangement of only one agitating finger in each plane and by the staggered arrangement of the stirring fingers to each other can be achieved with a minimum number of agitating a maximum stirring effect of the stirring device.
Eine besonders vorteilhafte Rührwirkung mit einem gleichmäßigen Antriebsmoment während des Betriebes lässt sich dadurch erreichen, dass die in axial zueinander beabstandeten Ebenen angeordneten Rührfinger auf einer von oben nach unten verlaufenden Schraubenlinie angeordnet sind.A particularly advantageous stirring action with a uniform drive torque during operation can be achieved in that the stirring fingers arranged in axially spaced-apart planes are arranged on a helix extending from top to bottom.
In vorteilhafter Weise wird eine gute Rührwirkung dadurch erreicht, dass die Schraubenlinie von oben nach unten entgegengesetzt zur Drehrichtung der Rührvorrichtung verläuft.Advantageously, a good stirring effect is achieved in that the helix extends from top to bottom opposite to the direction of rotation of the stirring device.
Um sicherzustellen das auch zu Klumpen zusammengebackte Materialansammlungen aufgebrochen werden können, damit die Dosieröffnung des Vorratsbehälters nicht verstopft wird, ist vorgesehen, dass im Bereich der Gelenkanordnung unterhalb der elastischen Rührfinger zwei gegenüberliegend angeordnete und sich in radialer Richtung erstreckende aus starrem Material bestehende Rührstifte angeordnet sind.To ensure that can be broken up into lumps zusammengebackte material collections so that the dosing of the reservoir is not clogged, it is provided that two oppositely disposed and extending in the radial direction of rigid material existing stirring pins are arranged in the region of the hinge assembly below the elastic stirring fingers.
Eine Reduzierung des Antriebsmomentes bei einer optimalen Rührwirkung wird dadurch erreicht, dass sich der Rührfinger zumindest in seinem radialen äußeren Bereich, auf seiner der Drehrichtung zugewandten Seite keilförmig in Drehrichtung verjüngt.A reduction of the drive torque with an optimal stirring effect is achieved in that the stirring finger tapers in a wedge shape in the direction of rotation, at least in its radial outer region, on its side facing the direction of rotation.
