Description

Die vorliegende Erfindung betrifft ein Winterdienst-Streugerät, umfassend einen der Aufnahme eines ersten Streustoffs dienenden Streustoffbehälter, eine in dessen Bodenbereich angeordnete Austrageinrichtung und eine von dieser beschickte, einen rotierend angetriebenen Streuteller aufweisende Ausbringeinrichtung, wobei weiterhin ein der Aufnahme eines zweiten Streustoffs dienender Sekundärbehälter vorgesehen ist. Insbesondere betrifft die vorliegende Erfindung ein Winterdienst-Streugerät gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a winter service spreader, comprising a grit container serving to hold a first grit, a discharge device arranged in its bottom area and a discharge device loaded by this and having a rotatingly driven spreader plate, with a secondary container serving to hold a second grit being provided . In particular, the present invention relates to a winter road spreader according to the preamble of claim 1.

Zur Glättebekämpfung auf Verkehrsflächen (Straßen, Wege, Plätze, Start-/Landebahnen, Vorfeld) werden verbreitet abstumpfende und/oder auftauende Streustoffe ausgebracht. Hierfür kommen üblicherweise Winterdienst-Streugeräte zum Einsatz, wie sie in diversen Ausführungen allgemein bekannt sind. Im Interesse einer möglichst hohen Effizienz verfügen solche Winterdienst-Streugeräte verbreitet über ein einen (starren oder flexiblen) Sekundärbehälter für einen zweiten Streustoff aufweisendes Flüssigkeitssystem, welches insbesondere dafür eingerichtet sein kann, den in dem Streustoffbehälter bevorrateten (typischerweise festen, z.B. körnigen) ersten Streustoff vor oder während des Ausbringens mit dem flüssigen zweiten Streustoff (z. B. Sole bzw. Salzlauge) zu befeuchten (vgl. beispielsweise EP 579311 A1 ). Denn nicht nur beschleunigt dies das Einsetzen der Tauwirkung von auftauendem Streustoff; auch wird die Haftung des Streustoffes auf der bestreuten Oberfläche verbessert, wodurch die Gefahr einer Verfrachtung von ausgebrachtem ersten Streustoff durch die Luftwirbel schnell fahrender Fahrzeuge reduziert wird. Ggf. kann das Flüssigkeitssystem dabei ergänzend für ein alternatives direktes Aufsprühen des zweiten, flüssigen Streustoffs auf die zu behandelnde Verkehrsfläche ausgebildet sein (vgl. beispielsweise DE 102010029142 A1 , WO 2014/135418 A1 , WO 2014/005647 A1 und WO 2014/005648 A1 ).To combat slippery roads (streets, paths, squares, runways, aprons), deadening and / or thawing grit is widely spread. For this purpose, winter service spreaders are usually used, as they are generally known in various designs. In the interest of the highest possible efficiency, such winter service spreaders widely have a (rigid or flexible) secondary container for a second spreading material, which can be set up in particular for the (typically solid, e.g. granular) first spreading material stored in the spreading material container or to moisten with the liquid second litter (e.g. brine or brine) during application (cf. for example EP 579311 A1 ). Because not only does this accelerate the onset of the thawing effect of thawing litter; the adhesion of the spreading material to the sprinkled surface is also improved, as a result of which the risk of the first spreading material being carried by the air vortices of fast moving vehicles is reduced. Possibly. can the fluid system in addition, it can be designed for an alternative direct spraying of the second, liquid spreading material onto the traffic area to be treated (cf. for example DE 102010029142 A1 , WO 2014/135418 A1 , WO 2014/005647 A1 and WO 2014/005648 A1 ).

Die DE 4429188 A1 offenbart ein Winterdienst-Streugerät bei dem sich granuliertes Streugut einerseits und flüssiges Streugut andererseits getrennt abwerfen lassen. Hierzu weist das Streugerät zusätzlich zu dem - dem Abwerfen von granuliertem Streugut dienenden - Streuteller, oberhalb von diesem angeordnet, eine ringförmige Schleuderscheibe auf, die dem Abwerfen von flüssigem Streugut dient, koaxial zum Streuteller rotiert und ebenfalls auf ihrer Oberseite mit Wurfschaufeln bestückt ist. Die Schleuderscheibe weist einen zentralen Durchbruch auf, wobei mindestens ein Aufgabeelement einer mit dem Sekundärbehälter kommunizierenden Aufgabeeinrichtung für zweiten, flüssigen Streustoff auf die ringförmige Schleuderscheibe gerichtet ist. Die Wurfschaufeln des Streutellers und der Streuscheibe sind dabei so angeordnet und ausgeführt, dass sich der Massenstrom des (von dem Streuteller abgeworfenen) granulierten Streuguts und der Massenstrom des von der Schleuderscheibe abgeworfenen flüssigen Streuguts vor Erreichen der Boden- oder Verkehrsflächen unter Herbeiführung einer Durchfeuchtung und/oder Benetzung des granulierten Streustoffs schneiden.The DE 4429188 A1 discloses a winter service spreader in which granulated grit on the one hand and liquid grit on the other hand can be thrown separately. For this purpose, the spreader has, in addition to the spreading plate, which is used to throw out granulated spreading material, an annular centrifugal disc, which is used to throw off liquid spreading material, rotates coaxially with the spreading plate and is also equipped with throwing blades on its upper side. The centrifugal disk has a central opening, at least one feed element of a feed device communicating with the secondary container for second, liquid scattering material being directed at the annular centrifugal disk. The throwing vanes of the spreading disc and the spreading disc are arranged and designed in such a way that the mass flow of the granulated grit (thrown from the spreading disc) and the mass flow of the liquid spreading material thrown from the centrifugal disc before reaching the ground or traffic areas, causing moisture penetration and / or cut the wetting of the granulated litter.

Um zwei verschiedene Düngersorten auszubringen, wurde eine prinzipiell ähnliche Ausbringeinrichtung mit einem - mit einer ersten Düngersorte beschickbaren - Streuteller und einer darüber angeordneten, gemeinsam mit dem Streuteller koaxial zu diesem rotierenden - mit einer zweiten Düngersorte beschickbaren - ringförmigen und kegelstumpfförmigen Schleuderscheibe bereits für einen Schleuderdüngerstreuer vorgeschlagen ( EP 0873678 A1 ).In order to spread two different types of fertilizer, a basically similar spreading device with a spreading plate - which can be loaded with a first type of fertilizer - and a spreading plate arranged above it and rotating together with the spreading plate coaxially to this - with a second type of fertilizer loadable - ring-shaped and frustoconical centrifugal disc already proposed for a centrifugal fertilizer spreader ( EP 0873678 A1 ).

EP 0873678 offenbart somit ein Winterdienst-Streugerät nach dem Oberbegriff des Anspruchs 1. EP 0873678 thus discloses a winter service spreader according to the preamble of claim 1.

Die vorliegende Erfindung ist darauf gerichtet, ein gegenüber dem vorstehend dargelegten Stand der Technik im Hinblick auf die Praxistauglichkeit verbessertes Winterdienst-Streugerät der gattungsgemäßen Art bereitzustellen.The present invention is aimed at providing a winter service spreader of the generic type which is improved compared to the prior art set out above with regard to practicality.

Gelöst wird diese Aufgabenstellung gemäß der vorliegenden Erfindung durch das in Anspruch 1 angegebene Winterdienst-Streugerät. Demgemäß zeichnet sich das Streugerät insbesondere dadurch aus, dass - im synergetischen funktionellen Zusammenwirken miteinander - oberhalb des Streutellers eine kegelstumpfförmig ausgeführte, auf ihrer Oberseite mit Mitnehmern bestückte, koaxial zum Streuteller rotierende, einen zentralen Durchbruch aufweisende ringförmige Schleuderscheibe vorgesehen ist und mindestens ein Aufgabeelement einer mit dem Sekundärbehälter kommunizierenden Aufgabeeinrichtung für zweiten Streustoff auf die ringförmige Schleuderscheibe gerichtet ist, wobei der vertikale Abstand der Schleuderscheibe zum Streuteller radial nach außen zunimmt. Die ringförmige Schleuderscheibe ist dabei kugelstumpfförmig ausgeführt.This object is achieved according to the present invention by the winter service spreader specified in claim 1. Accordingly, the spreader is particularly characterized in that - in synergetic functional interaction with each other - a frustoconical design, equipped on its top with drivers, rotating coaxially to the spreading plate, having a central opening is provided above the spreader plate and at least one task element with the secondary container communicating feed device for second scattering material is directed to the annular centrifugal disk, the vertical distance of the centrifugal disk to the spreading plate increases radially outward. The ring-shaped centrifugal disk is frusto-spherical.

Das mindestens eine auf die Schleuderscheibe gerichtete Aufgabeelement ist dabei Teil einer Aufgabeeinrichtung, welche (z. B. über eine Leitungsanordnung) mit dem Sekundärbehälter kommuniziert. Die Schleuderscheibe ist dabei ringförmig, so dass sie einen zentralen Durchbruch aufweist. Durch diesen hindurch ist der (darunter liegende) Streuteller von oben her zugänglich. Besonders bevorzugt sind dabei sowohl der Streuteller als auch die Schleuderscheibe leicht kegelstumpfförmig, wobei allerdings der Neigungswinkel der Schleuderscheibe (gegenüber der Horizontalen) deutlich größer ist als der Neigungswinkel des Streutellers gegenüber der Horizontalen.The at least one feeding element directed at the centrifugal disk is part of a feeding device which communicates with the secondary container (e.g. via a line arrangement). The centrifugal disk is ring-shaped so that it has a central opening. The spreading disc (below) is accessible from above through this. Both the spreading plate and the centrifugal disk are particularly preferably slightly frustoconical, although the angle of inclination of the centrifugal disk (relative to the horizontal) is significantly greater than the angle of inclination of the spreading plate relative to the horizontal.

Mittels des erfindungsgemäßen Streugeräts lassen sich zweite Streustoffe von unterschiedlichster Art und Konsistenz ausbringen, und zwar unabhängig von dem ersten Streustoff. Dies führt zu einer bisher nicht bekannten Flexibilität hinsichtlich des Einsatzes des Streugeräts unter verschiedensten Einsatzbedingungen, und das bei nur minimalem baulichen und apparativen Aufwand. Wenngleich dies eine Schwerpunktanwendung der vorliegenden Erfindung darstellt, so ist die Nutzung des erfindungsgemäßen Streugeräts doch keineswegs auf die Ausbringung eines flüssigen zweiten Streustoffs beschränkt. Vielmehr kann es sich beispielsweise sowohl beim ersten als auch beim zweiten Streustoff um einen körnigen Feststoff handeln. Eine denkbare Anwendung des erfindungsgemäßen Winterdienst-Streugeräts ist beispielhaft, dass der erste Streustoff Salz (oder ein anderer auftauender Streustoff) ist und der zweite Streustoff Splitt (oder ein anderer abstumpfender Streustoff). So kann unter Nutzung des erfindungsgemäßen Winterdienst-Streugeräts das Mischungsverhältnis von Salz und Splitt individuell bedarfsweise nach den jeweiligen örtlichen Bedingungen eingestellt bzw. an diese angepasst werden, um einen optimalen Streuerfolg mit minimalem Aufwand, zu geringsten Kosten für den Streustoff und mit minimalen negativen Auswirkungen auf die Umwelt zu erzielen.By means of the spreading device according to the invention, second spreading materials of the most varied types and consistencies can be spread, specifically independently of the first spreading material. This leads to a previously unknown flexibility with regard to the use of the spreader under a wide variety of operating conditions, and that with only minimal structural and equipment expenditure. Although this represents a main application of the present invention, the use of the spreader according to the invention is by no means restricted to the application of a second liquid spreading material. Rather, both the first and the second litter can be a granular solid, for example. A conceivable application of the winter road spreader according to the invention is, for example, that the first grit is salt (or another thawing grit) and the second grit is grit (or another dulling grit). So can using the winter road spreader according to the invention Mixing ratio of salt and grit can be individually set or adapted to the respective local conditions as required in order to achieve optimal spreading success with minimal effort, at the lowest cost for the spreading material and with minimal negative effects on the environment.

Besonders gering ist der apparative und bauliche Aufwand, wenn, gemäß einer ersten bevorzugten Weiterbildung der vorliegenden Erfindung, die Schleuderscheibe fest mit dem Streuteller verbunden ist. Namentlich kann in diesem Sinne dabei die Schleuderscheibe fest mit von dem Streuteller aufragenden Wurfschaufeln verbunden sein. Da in diesem Falle der Streuteller und die ringförmige Schleuderscheibe stets mit identischer Drehzahl rotieren, sind besonders bevorzugt die Mitnehmer verstellbar auf der Schleuderscheibe angebracht. So kann - durch Verstellen der Mitnehmer - die Abwurfcharakteristik der Schleuderscheibe modifiziert werden insbesondere dahingehend, dass bei einer bestimmten Drehzahl die Wurfweiten des mittels des Streutellers ausgebrachten ersten Streustoffs und des mittels der ringförmigen Schleuderscheibe ausgebrachten zweiten Streustoffs einander entsprechen. Im weiteren Sinne ist auch eine leichte Austauschbarkeit der Mitnehmer gegen andere als eine solche Verstellbarkeit der Mitnehmer anzusehen. Bei typischen Anwendungen der vorliegenden Erfindung wird im Übrigen die Geometrie der auf der Schleuderscheibe vorgesehenen Mitnehmer mehr oder weniger ausgeprägt von der Geometrie der von dem Streuteller aufragenden Wurfschaufeln abweichen.The outlay in terms of apparatus and construction is particularly low if, according to a first preferred development of the present invention, the centrifugal disk is firmly connected to the spreading plate. In this context, in particular, the centrifugal disk can be firmly connected to throwing blades protruding from the spreading plate. Since in this case the spreading plate and the annular centrifugal disk always rotate at the same speed, the drivers are particularly preferably adjustably attached to the centrifugal disk. By adjusting the drivers, the throwing characteristics of the centrifugal disc can be modified in particular so that at a certain speed the throwing distances of the first spreading material applied by means of the spreading disc and the second spreading material applied by means of the annular centrifugal disc correspond to one another. In a broader sense, easy interchangeability of the drivers with others is also to be regarded as such an adjustability of the drivers. In typical applications of the present invention, the geometry of the drivers provided on the centrifugal disk will more or less deviate from the geometry of the throwing vanes protruding from the spreading plate.

Auch wenn, wie weiter oben dargelegt, die vorliegende Erfindung nicht auf die Verwendung von flüssigem zweitem Streustoff beschränkt ist, so ist sie doch für derartige Anwendungen mit besonders großem Vorteil einsetzbar. Insoweit ist gemäß einer anderen bevorzugten Weiterbildung der Erfindung vorgesehen, dass der Sekundärbehälter spezifisch für die Aufnahme von flüssigem zweitem Streustoff ausgeführt und zwischen dem Sekundärbehälter und der Aufgabeeinrichtung für den zweiten Streustoff eine mit einer Pumpe ausgestattete Leitungsanordnung vorgesehen ist. Der Pumpe ist dabei besonders bevorzugt eine Ventileinheit nachgeschaltet, mittels derer zwischen einer Zufuhr des (flüssigen) zweiten Streustoffs zu der der Schleuderscheibe zugeordneten Aufgabeeinrichtung und einer Zufuhr des zweiten Streustoffs zu der Ausbringeinrichtung für den ersten Streustoff, um diesem beigemischt zu werden, umgeschaltet werden kann.Even if, as explained above, the present one Invention is not limited to the use of liquid second scattering material, it can be used for such applications with particularly great advantage. In this respect, according to another preferred development of the invention, it is provided that the secondary container is specifically designed to hold liquid second litter and a line arrangement equipped with a pump is provided between the secondary container and the feed device for the second litter. The pump is particularly preferably followed by a valve unit, by means of which it is possible to switch between a supply of the (liquid) second spreading material to the feeding device assigned to the centrifugal disk and a supply of the second spreading material to the application device for the first spreading material to be mixed with it .

Eine wiederum andere bevorzugte Weiterbildung der vorliegenden Erfindung zeichnet sich dadurch aus, dass die Ausbringeinrichtung (für den ersten Streustoff) eine den Streuteller durch den zentralen Durchbruch der Schleuderscheibe hindurch beschickende Schütte umfasst. An der Schütte kann dabei insbesondere ein mit dem Sekundärbehälter verbundener Kanal für den zweiten Streustoff münden. Eine auf diese Weise mögliche Beimengung des zweiten Streustoffs zu dem ersten Streustoff, bevor dieser auf den Streuteller gelangt, begünstigt eine innige Vermischung der beiden Streustoffe auf dem Streuteller.Yet another preferred development of the present invention is characterized in that the dispensing device (for the first spreading material) comprises a chute which feeds the spreading plate through the central opening of the centrifugal disk. In particular, a channel for the second litter that is connected to the secondary container can open out at the chute. An admixture of the second spreading material to the first spreading material, which is possible in this way, before it reaches the spreading plate, favors an intimate mixing of the two spreading materials on the spreading plate.

Gemäß einer nochmals anderen bevorzugten Weiterbildung der vorliegenden Erfindung ist die Aufgabeeinrichtung dergestalt lageverstellbar, dass mit ihr zweiter Streustoff wahlweise auch durch den zentralen Durchbruch der Schleuderscheibe hindurch auf den Streuteller aufbringbar ist. Dies stellt ein weiteres die hohe Flexibilität hinsichtlich der Einsetzbarkeit des erfindungsgemäßen Streugeräts unter verschiedensten Bedingungen begünstigendes Merkmal dar. Im Übrigen ist allerdings die Aufgabeeinrichtung bevorzugt in einer einstellbaren Stellung dergestalt oberhalb der Schleuderscheibe fixierbar, dass sie bei einem - dem Einstellen der seitlichen Streubildlage des ausgebrachten ersten Streustoffs relativ zum Winterdienstfahrzeug dienenden - Verschwenken des Streutellers und der Schleuderscheibe ihre Lage relativ zur Schleuderscheibe beibehält. So verändert sich bei dem besagten seitlichen Verschwenken des Streutellers und der Schleuderscheibe die Streubildlage des von der Schleuderscheibe abgeworfenen zweiten Streustoffs auf der zu behandelnden Verkehrsfläche gleichsinning zur Veränderung der Streubildlage des über den Streuteller ausgebrachten ersten Streustoffs.According to yet another preferred development of the present invention, the position of the feeding device can be adjusted in such a way that it can optionally be used to apply the second scattering material to the scattering plate through the central opening of the centrifugal disk. This sets Another feature which promotes the high flexibility with regard to the usability of the spreading device according to the invention under a wide variety of conditions. Otherwise, however, the feed device can preferably be fixed in an adjustable position above the centrifugal disk in such a way that when the lateral spread pattern position of the first spreading material is set relative to the Serving winter service vehicle - pivoting of the spreading plate and the centrifugal disk maintains their position relative to the centrifugal disk. During said lateral pivoting of the spreading plate and the centrifugal disc, the spread pattern position of the second spreading material thrown off by the centrifugal disc on the traffic area to be treated changes in the same way as the spreading pattern position of the first spreading substance spread over the spreading plate.

Weiterhin kann bevorzugt vorgesehen sein, dass die Aufgabeeinrichtung eine Mehrzahl von in Umfangsrichtung zueinander versetzt angeordneten Aufgabeelementen für den zweiten Streustoff aufweist. Insbesondere kann dabei eine (ggf. weitere) Ventileinrichtung zur wahlweisen Einspeisung von zweitem Streustoff in die verschiedenen Aufgabeelemente vorgesehen sein. Hierdurch lässt sich auf einfache Weise auf den Auftreffpunkt des zweiten Streustoffs auf die Schleuderscheibe und somit die Abwurfcharakteristik für den zweiten Streustoff von dieser Einfluss nehmen.Furthermore, it can preferably be provided that the dispensing device has a plurality of dispensing elements for the second scattering material, which are arranged offset from one another in the circumferential direction. In particular, a (possibly further) valve device can be provided for the optional feeding of a second spreading material into the various feed elements. In this way, the point of impact of the second scattering material on the centrifugal disk and thus the throwing characteristics for the second scattering material can be influenced by the latter in a simple manner.

Im Folgenden wird die vorliegende Erfindung anhand eines in der Zeichnung veranschaulichten bevorzugten Ausführungsbeispiels näher erläutert. Angesichts dessen, dass das Streugerät im Übrigen dem hinlänglich bekannten Stand der Technik entsprechen kann, beschränkt sich die Zeichnung dabei auf die Darstellung der für das Ausbringen beider Streustoffe bestimmten, heckseitig an dem Streugerät angeordneten Baugruppe.The present invention is explained in more detail below with reference to a preferred exemplary embodiment illustrated in the drawing. In view of the fact that the spreader can otherwise correspond to the well-known state of the art, the drawing is limited on the representation of the assembly intended for the application of both spreading materials and arranged on the rear of the spreading device.

Das somit in der Zeichnung nur teilweise dargestellte Streugerät umfasst in als solches bekannter Weise einen der Aufnahme eines ersten Streustoffs dienenden Streustoffbehälter und eine in dessen Bodenbereich angeordnete Austrageinrichtung (Förderband oder Förderschnecke). Letztere beschickt, wiederum in als solches bekannter Weise, über eine Schütte 1 einen Streuteller 2, welcher Teil einer Ausbringeinrichtung 3, auf seiner Oberseite mit Wurfschaufeln 4 bestückt und mittels eines Hydraulikmotors 5 um die im Wesentlichen vertikale Rotationsachse X drehbar angetrieben ist.The spreading device thus only partially shown in the drawing comprises, in a manner known per se, a spreading material container serving to receive a first spreading material and a discharge device (conveyor belt or screw conveyor) arranged in its bottom area. The latter feeds, again in a manner known as such, via a chute 1 a spreading plate 2, which is part of a discharge device 3, equipped on its upper side with throwing blades 4 and is rotatably driven about the essentially vertical axis of rotation X by means of a hydraulic motor 5.

Mit dem Streuteller 2, nämlich mit dessen Wurfschaufeln 4, ist eine ringförmige Schleuderscheibe 6 fest verbunden. Sowohl der Streuteller 2 als auch die Schleuderscheibe 6 sind nicht plan, sondern vielmehr leicht kegelstumpfförmig. Der Neigungswinkel der Schleuderscheibe (gegenüber der Horizontalen) ist dabei mit etwa 15° allerdings deutlich größer als der Neigungswinkel des Streutellers gegenüber der Horizontalen (etwa 9°). Auf diese Weise nimmt der vertikale Abstand der Schleuderscheibe zum Streuteller (bzw. die lichte Höhe der zwischen dem Streuteller 2 und der Schleuderscheibe 6 durch die Wurfschaufeln 4 definierten Kanäle) radial nach außen zu.With the spreading plate 2, namely with its throwing vanes 4, an annular centrifugal disk 6 is firmly connected. Both the spreading plate 2 and the centrifugal disk 6 are not flat, but rather slightly frustoconical. The angle of inclination of the centrifugal disc (with respect to the horizontal) is at around 15 °, however, significantly larger than the angle of inclination of the spreader disc with respect to the horizontal (approx. 9 °). In this way, the vertical distance between the centrifugal disc and the spreading plate (or the clear height of the channels defined between the spreading plate 2 and the centrifugal disc 6 by the throwing vanes 4) increases radially outward.

Die Schleuderscheibe 6 weist an ihrer Oberseite Mitnehmer 7 auf, welche sich von dem äußeren Umfang 8 bis zu dem zentralen Durchbruch 9 erstrecken. Durch den zentralen Durchbruch 9 der Schleuderscheibe 6 hindurch ist der Streuteller 2 von oben her zugänglich, wobei sich die Wurfschaufeln 4 des Streutellers 2 weiter radial nach innen erstrecken als die Mitnehmer 7 der Schleuderscheibe 6; sie ragen somit in den Bereich des zentralen Durchbruchs 9 der Schleuderscheibe 6 hinein. Die Schütte 1 ist in ihrem unteren Bereich so ausgeführt, dass der sie verlassende erste Streustoff durch den Durchbruch 9 der Schleuderscheibe 6 hindurch auf den Streuteller 2 gelangt.The centrifugal disk 6 has drivers 7 on its upper side, which extend from the outer circumference 8 to the central opening 9. Through the central opening 9 of the centrifugal disk 6 is the Spreading plate 2 accessible from above, the throwing blades 4 of the spreading plate 2 extending further radially inward than the drivers 7 of the centrifugal disk 6; they thus protrude into the area of the central opening 9 of the centrifugal disk 6. The lower area of the chute 1 is designed in such a way that the first spreading material leaving it reaches the spreading plate 2 through the opening 9 of the centrifugal disk 6.

Zwei Aufgabeelemente 11 in Form von auf die Schleuderscheibe 6 gerichteten Solerohren 12 stellen einen Teil einer Aufgabeeinrichtung 13 dar, die über eine mit einer Solepumpe ausgestattete Leitungsanordnung mit einem (nicht gezeigten) Sekundärbehälter kommuniziert und mittels derer in dem Sekundärbehälter bevorrateter (vorliegend flüssiger) zweiter Streustoff auf die Schleuderscheibe 6 aufgebbar ist. Zwischen der dem Sekundärbehälter nachgeschalteten Solepumpe und den Solerohren 12 ist in der betreffenden Leitungsanordnung eine (nicht gezeigte) Ventileinrichtung vorgesehen, mittels derer wählbar ist, in welches der beiden Solerohre 12 dem Sekundärbehälter entnommene Sole einspeisbar ist. Mittels der Ventileinrichtung ist weiterhin einstellbar, ob und ggf. in welcher Menge Sole - über den Anschluss 14 - einem (flachen) Kanal 15 zugeführt wird, welcher an der Schütte 1 in dem Bereich von deren unteren Ende mündet, wobei durch die Ventileinheit die Zufuhr von zweitem Streustoff zu der Aufgabeeinheit 13 dabei parallel reduziert oder vollständig unterbrochen werden kann. Der Kanal 15 und der untere Endabschnitt der Schütte 1 sind dabei dergestalt zueinander ausgerichtet, dass den Kanal 15 verlassende Sole in den die Schütte 1 verlassenden Strom aus erstem Streustoff eintritt.Two feed elements 11 in the form of brine pipes 12 directed at the centrifugal disk 6 represent part of a feed device 13 which communicates with a secondary container (not shown) via a line arrangement equipped with a brine pump and by means of which second spreading material (in this case liquid) stored in the secondary container can be applied to the centrifugal disk 6. Between the brine pump connected downstream of the secondary container and the brine pipes 12, a valve device (not shown) is provided in the relevant line arrangement, by means of which it is possible to select into which of the two brine pipes 12 the brine removed from the secondary container can be fed. The valve device can also be used to set whether and, if applicable, in what amount brine - via the connection 14 - is fed to a (flat) channel 15, which opens into the chute 1 in the area of its lower end, the feed through the valve unit of the second litter to the feed unit 13 can be reduced in parallel or completely interrupted. The channel 15 and the lower end section of the chute 1 are aligned with one another in such a way that brine leaving the channel 15 enters the stream of first litter leaving the chute 1.

Parallel zur Schütte 1 erstreckt sich ein Tragrohr 16, an welchem eine Lagerplatte 17 gelagert ist, und zwar über das Gelenk 18 um die im Wesentlichen vertikale Schwenkachse Y verschwenkbar. Auf der Lagerplatte 17 ist der Hydraulikmotor 5 aufgebaut, an dessen Welle 19 der Streuteller 2 angebracht ist, und zwar mit dessen zentralem Kern 20. Die Welle 19 ist dabei in einer mit der Lagerplatte 17 an deren Unterseite fest verbundenen Lagerhülse 21 drehbar gelagert. An dieser Lagerhülse 21 ist ein Halter 10 für die beiden Solerohre 12 angebracht, welcher einen zweiarmigen Träger 22 und eine an einem von dessen Armen angebrachte Traverse 23 umfasst. Die Traverse 23 ist dabei an dem Träger 22 in unterschiedlichen Positionen fixierbar.A support tube 16 extends parallel to the chute 1 which a bearing plate 17 is mounted, namely pivotable about the essentially vertical pivot axis Y via the joint 18. On the bearing plate 17, the hydraulic motor 5 is built, on whose shaft 19 the spreading plate 2 is attached, with its central core 20. The shaft 19 is rotatably mounted in a bearing sleeve 21 fixedly connected to the bearing plate 17 on its underside. A holder 10 for the two brine pipes 12 is attached to this bearing sleeve 21, which holder comprises a two-armed support 22 and a cross member 23 attached to one of its arms. The cross member 23 can be fixed on the carrier 22 in different positions.
