Description
Winterdienst-Streugerät Winter service spreader
Die Erfindung betrifft ein Winterdienst-Streugerät für den Aufbau auf ein Fahrzeug; sie betrifft ferner einen Streustoffbehälter für ein derartiges Streugerät zur Aufnahme von körnigem Streugut.The invention relates to a winter service spreader for mounting on a vehicle; it also relates to a spreading material container for such a spreading device for receiving granular spreading material.
Bekannte Streugeräte besitzen üblicherweise einen im Querschnitt V-förmigen Streustoffbehälter aus Stahl, in dessen ßodenbereich eine in Längsrichtung des Streube¬ hälters verlaufende Fördereinrichtung, bevorzugt in Form eines Schnecken- oder Bandförderers, angeordnet ist. Mittels dieser Fördereinrichtung wird das Streugut einem Streustoffverteiler zugeführt, der am hinteren Ende des Streubehälters an dessen Außenseite angeordnet ist.Known spreading devices usually have a steel V-shaped spreading material container, in the bottom area of which a conveying device running in the longitudinal direction of the spreading container, preferably in the form of a screw or belt conveyor, is arranged. By means of this conveying device, the spreading material is fed to a spreading material distributor which is arranged at the rear end of the spreading container on the outside thereof.
Der Streustoffbehälter ist entweder auf der Ladepritsche eines Fahrzeugs oder direkt auf dem Fahrzeug-Chassis befestigt, wobei das Fahrzeug als Anhänger oder selbst¬ fahrend ausgebildet sein kann.The spreading material container is either attached to the loading platform of a vehicle or directly on the vehicle chassis, it being possible for the vehicle to be designed as a trailer or self-propelled.
Je nach Einsatzbedingungen gibt es unterschiedliche Behältergrößen, welche individuell aus Stahlplatten und -profilen zusammengeschweißt werden. Obwohl die Stahlwände mit einem Anstrich als Korrosionsschutz versehen Depending on the operating conditions, there are different container sizes, which are welded together individually from steel plates and profiles. Although the steel walls are painted to protect against corrosion
sind, widerstehen sie auf Dauer nicht dem aggressiven Streugut, welches ständig an den Behälterwänden reibt, und zwar nicht nur beim normalen Füll- und Entleerungs¬ vorgang, sondern besonders beim Lockern von gefrorenem oder festsitzendem Streugut, z.B. mit der Schaufel.they do not withstand the aggressive grit that constantly rubs against the container walls, not only during the normal filling and emptying process, but especially when loosening frozen or stuck grit, e.g. with the shovel.
Die vorliegende Erfindung schlägt demgegenüber eine Lösung vor, welche die genannten Nachteile vermeidet; sie ist gekennzeichnet durch die folgenden Merkmale:In contrast, the present invention proposes a solution which avoids the disadvantages mentioned; it is characterized by the following features:
1. Es ist eine Bodengruppe vorhanden, auf welcher ein Streustoff-Behälter aufgebaut ist;1. There is a floor assembly on which a grit container is built;
2. die Bodengruppe umfaßt eine in Längsrichtung des Behälters zu einem Streuverteiler fördernde Band¬ oder Schnecken-Fördereinrichtung;2. the bottom assembly comprises a belt or screw conveyor device conveying in the longitudinal direction of the container to a litter distributor;
3. die Bodengruppe umfaßt ferner einen Bodenrahmen, auf welchem der Behälter abgestützt ist;3. the floor assembly further comprises a floor frame on which the container is supported;
4. der Behälter ist aus einzelnen vorgefertigten Wand¬ elementen zusammengesetzt.4. The container is composed of individual prefabricated wall elements.
Durch geeignete Kombination der den Behälter bildenden Wandelemente können Behälter unterschiedlichster Größe ohne individuellen Zuschnitt und bei Vermeidung von Schweißarbeiten zusammengebaut werden. Die vorgeschlagene By a suitable combination of the wall elements forming the container, containers of different sizes can be assembled without individual cutting and with the avoidance of welding work. The proposed one
Elementbauweise eröffnet ferner die Möglichkeit der Verwendung anderer Materialien als Stahl. Die Behältergröße kann vorteilhaft an ein jeweils vorhandenes Fahrzeug- Chassis angepaßt werden, so daß sich Sonderkonstruktionen erübrigen. Die Behälter-Wandelemente können auf Lager gefertigt werden und ermöglichen somit eine flexible Bedarfsanpassung bei einfacher und schneller Herstellung.Element construction also opens up the possibility of using materials other than steel. The container size can advantageously be adapted to an existing vehicle chassis, so that special constructions are unnecessary. The container wall elements can be manufactured in stock and thus enable flexible adaptation to requirements with simple and quick production.
In einer besonders vorteilhaften Ausgestaltung umfaßt der Behälter neben einer Frontwand und einer Rückwand eine gerade Anzahl von untereinander gleichen Wandelemen¬ ten, d.h. jede Seitenwand des Behälters besteht aus einer oder mehreren Seitenwandelementen, welche in Behälter¬ längsrichtung aneinandergereiht sind.In a particularly advantageous embodiment, the container comprises, in addition to a front wall and a rear wall, an even number of mutually identical change elements, i.e. each side wall of the container consists of one or more side wall elements which are lined up in the longitudinal direction of the container.
Dementsprechend genügt eine einzige Form bzw. Vorrichtung zur Herstellung der Seitenwandelemente. In einer bevorzug¬ ten Ausführungsform mit einer Band-FÖrdereinrichtung besteht ferner die Möglichkeit, auch die Frontwand und die Rückwand untereinander gleich auszubilden, indem beide Wände jeweils eine Öffnung für die über den Behälter vorne und hinten hinaus verlängerte Band-Fördereinrichtung aufweisen. Die Lagerböcke für die Band-Fördereinrichtung sind also in diesem Fall außerhalb des Behälters an Accordingly, a single mold or device is sufficient to produce the side wall elements. In a preferred embodiment with a belt conveyor device, there is also the possibility of designing the front wall and the rear wall with one another in the same way, in that both walls each have an opening for the belt conveyor device which is extended beyond the container at the front and rear. The bearing blocks for the belt conveyor are in this case outside of the container
dessen vorderem bzw. rückwärtigem Ende angeordnet.its front or rear end arranged.
Die oben aufgezeigten Korrosionsprobleme können nach einem besonders vorteilhaften Merkmal der Erfindung dadurch vermieden werden, daß die Wandelemente aus Kunst¬ stoff oder als Verbundelemente aus Kunststoff und Stahl hergestellt sind, und zwar bevorzugt als Hohl örper, wobei dieser durch eine steife SchaumstoffStruktur ganz oder teilweise ausgefüllt sein kann.According to a particularly advantageous feature of the invention, the corrosion problems outlined above can be avoided in that the wall elements are made of plastic or as composite elements made of plastic and steel, preferably as hollow bodies, these being completely or partially filled by a rigid foam structure can be.
Besonders geeignete Werkstoffe sind Polyäthylen oder Polypropylen; günstig ist auch eine Herstellung der Hohlkörper im Schleudergußverfahren, z.B. aus Polyurethan.Particularly suitable materials are polyethylene or polypropylene; It is also favorable to manufacture the hollow bodies by centrifugal casting, e.g. made of polyurethane.
Ein zweckmäßige Ausbildung der Seitenwandelemente sieht vor, daß diese stirnseitig Flansche aufweisen, in welchen jeweils Verbindungsmittel zu einem benachbarten Wandelement aufgenommen sind. Die Wandelemente werden bevorzugt miteinander verschraubt, wobei in der Verbindungsfläche elastische Einlagen zum Zwecke der Dichtung und des Toleranzausgleichs vorgesehen sein können.An expedient design of the side wall elements provides that they have flanges on the end face, in each of which connection means to an adjacent wall element are accommodated. The wall elements are preferably screwed together, and elastic inserts can be provided in the connecting surface for the purpose of sealing and tolerance compensation.
Bei zweckmäßig V-förmigem Innenquerschnitt des Behälters können die Seitenwandelemente nach außen zu Flüssigkeits- tanks verbreitert sein, ohne daß dadurch die Gesamtbreite des Streustoff-Behälters vergrößert wird. Solche Flüssig- keitstanks sind erforderlich als Solespeicher für das Feuchtsalzstreuen, wobei jeder Tank über eine Soleleitung mit dem Streustoffverteiler verbunden ist. Dabei werden über den Streustoffverteiler Sole und körniges Streugut ausgebracht. Selbstverständlich besitzt jeder durch ein Seitenwandele ent gebildeter Flüssigkeitstank einen oberen Einfüllstutzen und einen unteren Ablaßstutzen.If the container has a suitably V-shaped internal cross section, the side wall elements can tanks can be widened without increasing the overall width of the spreading material container. Such liquid tanks are required as brine stores for damp salt spreading, each tank being connected to the spreading material distributor via a brine line. Brine and granular spreading material are spread over the spreading material distributor. Of course, each liquid tank formed by a side wall has an upper filler neck and a lower drain neck.
In einer Ausführungsform mit einer Band-Fördereinrichtung ist ferner vorgesehen, daß die Seitenwandelemente jeweils in ihrem unteren Raήdbereich eine Ausformung zur Außenseite hin besitzen, deren horizontaler Abschnitt den Seitenrand des Förderbands übergreift und deren vertikaler Abschnitt auf dem Bodenrahmen befestigt ist. Der Bodenrahmen besteht zweckmäßig aus Längs- und Querholmen, wobei die Abstände zwischen benachbarten Querholmen jeweils der Länge eines Seitenwandelements entsprechen.In one embodiment with a belt conveyor, it is further provided that the side wall elements each have a shape toward the outside in their lower wheel area, the horizontal section of which overlaps the side edge of the conveyor belt and the vertical section of which is fastened to the floor frame. The floor frame expediently consists of longitudinal and transverse bars, the distances between adjacent transverse bars each corresponding to the length of a side wall element.
Zusätzlich können die Wandelemente im Bereich ihres oberen Randes mittels stab- oder seilartiger Spannelemente verbunden sein; dies ermöglicht Materialeinsparungen, insbesondere bei der Herstellung der Wandelemente aus Kunststoff. Ein geeignetes Spannelement kann beispielsweise ein entlang des oberen Randes umlaufendes Seil sein, an welchem alle Wandelemente aufgefädelt sind; es kommen aber auch quer- und l ngsverspannte Seile oder Zugstäbe in Frage.In addition, the wall elements can be connected in the region of their upper edge by means of rod-like or rope-like tensioning elements; this enables material savings, particularly in the manufacture of the wall elements Plastic. A suitable tensioning element can be, for example, a rope running around the upper edge, on which all wall elements are threaded; cross-ropes and longitudinally tensioned ropes or tension rods are also possible.
Durch den modularen Aufbau des erfindungsgemäßen Streustoff- Behälters ergeben sich erhebliche Einsparungen bei dessen Herstellung, insbesondere dann, wenn für alle Seitenwand¬ elemente aus Kunststoff dieselbe Form verwendet wird und wenn dies auch für die Frontwand und die Rückwand gilt, so daß insgesamt nur zwei Formen erforderlich sind. Für den Fall der- Beschädigung eines Wandelements kann dieses durch ein Neues ersetzt werden, während der übrige Behälter weiterhin verwendbar ist.The modular structure of the scattering material container according to the invention results in considerable savings in its manufacture, in particular if the same shape is used for all side wall elements made of plastic and if this also applies to the front wall and the rear wall, so that in total only two shapes required are. In the event of damage to a wall element, it can be replaced by a new one, while the rest of the container can still be used.
Bei der Verwendung von Kunststoff-Wandelementen erübrigt sich das Anbringen eines zusätzlichen Korrosionsschutzes. Überdies neigt das körnige Streugut weniger zum Verbacken mit der Kuπststoff-Wandfläche, verglichen mit dem bekannten Stahlbeh lter. Daraus ergibt sich die Möglichkeit einer geringeren Seitenwandneigung und damit eines niedrigeren Schwerpunkts des Behälters, was sich vorteilhaft auf die Fahrzeugstabilität auswirkt. Verglichen mit einem Stahlbehälter wiegt der erfindungsgemäße Streustoff- Behälter aus Kunststoff lediglich etwa die Hälfte.When using plastic wall elements, there is no need to apply additional corrosion protection. In addition, the granular grit tends to bake less with the plastic wall surface compared to the known steel container. This results in the possibility of a lower sidewall inclination and thus a lower center of gravity of the container, which has an advantageous effect on vehicle stability. Compared to one Steel container, the plastic litter container according to the invention only weighs about half.
Ein weiterer Vorteil zugunsten der Verwendung von Kunst¬ stoff-Wandelementen besteht in einer besseren Wärme¬ isolierung, wodurch eine gute Schüttfähigkeit des Streuguts auch bei sehr niedrigen Außentemperaturen erhalten bleibt.A further advantage in favor of the use of plastic wall elements is better thermal insulation, as a result of which the spreading material has good pourability even at very low outside temperatures.
Im Folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung erläutert. Es zeigt:An exemplary embodiment of the invention is explained below with reference to the drawing. It shows:
