Description

Die Erfindung betrifft eine Vorrichtung zum Ausbringen von Streugut umfassend einen Streustoffbehälter mit einer Streustoffaustragöffnung und einem Streustoff-Förderer in Form eines Förderbands, auf welchem ein aus dem Behälter durch die Austragsöffnung ausgetragener Streustoffteppich einem Streustoffverteiler zugeführt wird.The invention relates to a device for dispensing grit a grit container with a grit discharge opening and a grit conveyor in the form of a conveyor belt on which one from the container through the The discharge opening of the spreading carpet that has been discharged into a spreading material distributor is fed.

Vorgenannte Streuvorrichtungen finden beispielsweise Anwendung auf Winterdienstfahrzeugen zum Ausstreuen von Salz. Der Streustoffbehälter besitzt typischerweise einen konischen, trichterartigen Querschnitt, an dessem Grund das Förderband liegt. Das Förderband bewegt sich unter dem in dem Streustoffbehälter befindlichen Salzstock entgegen der Fahrtrichtung des Winterdienstfahrzeugs, zieht dabei Salz unter dem Salzstock ab und fördert einen Salzteppich durch die Streustoffaustragöffnung hinaus zu dem Streustoffverteiler, üblicherweise eine Schleuderscheibe bzw. ein sogenannter Streuteller. Die Höhe und Breite des auf dem Förderband entstehenden Salzteppichs wird durch den Öffnungsquerschnitt der Streustoffaustragöffnung bestimmt. Die gewünschte Streumenge pro Fahrbahnfläche wird bei vorgegebenem Öffnungsquerschnitt abhängig von der Fahrgeschwindigkeit durch Einstellen der Förderbandgeschwindigkeit dosiert.The aforementioned spreading devices are used, for example Winter service vehicles for spreading salt. The grit container has typically a conical, funnel-like cross-section, for which reason the Conveyor belt lies. The conveyor belt moves below that in the Grit container located opposite the direction of travel of the Winter service vehicle, pulls salt from under the salt dome and promotes you Salt carpet through the grit discharge opening to the grit distributor, usually a centrifugal disc or a so-called spreading disc. The height and width of the salt carpet created on the conveyor belt is determined by the Opening cross-section of the grit discharge opening determined. The desired The spread rate per lane area is given a given opening cross-section depending on the driving speed by adjusting the Conveyor belt speed metered.

Problematisch ist die Verarbeitung von Streugut, welches zum Verkleben neigt, beispielsweise Siedesalz. Wenn sehr feines Siedesalz eine Feuchtigkeit von über einem Gewichtsprozent besitzt, beginnt diese sehr stark zusammenzukleben. Dieser Effekt verstärkt sich bei Temperaturen unter -3°C. Der auf dem Förderband transportierte Streustoffteppich bildet dann einen Salzkuchen, der brikettartig vom Förderende des Transportbands abbricht und in den Streutrichter fällt. Durch dieses klumpenweise Abbrechen entsteht dann ein sehr ungleichmäßiges, pulsierendes Streubild mit Stellen besonders hoher Konzentration und anderen Stellen, in denen überhaupt kein Salz auf die Fahrbahn verteilt wird. Dieses Problem ist bei geringen Fahrzeuggeschwindigkeiten von 5 km/h und darunter besonders ausgeprägt. Es können mehrere Sekunden vergehen, in denen kein Salz auf den Streuteller fällt.Difficulty is the processing of grit, which tends to stick, for example evaporated salt. If very fine evaporated salt is a moisture of over has a weight percent, it begins to stick together very strongly. This effect increases at temperatures below -3 ° C. The one on the The conveyor belt transported by the spreading material carpet then forms a salt cake breaks off like a briquette from the conveyor end of the conveyor belt and into the spreading hopper falls. Through this lump-wise breaking off a very then arises uneven, pulsating scatter pattern with places particularly high Concentration and other places where there is no salt on the road at all is distributed. This problem is at low vehicle speeds of 5 km / h and particularly pronounced below. It can take several seconds in which no salt falls on the spreading disc.

Aufgabe der vorliegenden Erfindung ist es daher, eine Lösung zu dem Problem vorzuschlagen, wie zur Verklebung neigendes Siedesalz auch bei geringen Förderbandgeschwindigkeiten zuverlässig ausgetragen werden kann.The object of the present invention is therefore to find a solution to the problem to propose, like evaporated salt, which tends to stick, even at low levels Conveyor belt speeds can be reliably carried out.

Diese Aufgabe wird durch eine Vorrichtung gemäß dem Anspruch 1 sowie einem Winterdienstfahrzeug mit einer solchen Vorrichtung gelöst. In davon abhängigen Ansprüchen sind vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung angegeben.This object is achieved by a device according to claim 1 and a Winter service vehicle solved with such a device. Dependent on it Claims are advantageous developments and refinements of the invention specified.

Erfindungsgemäß ist außerhalb des Streustoffbehälters und vor dem Förderende des Förderbands ein Streustoffteppichzerkleinerer vorgesehen. Dabei handelt es sich vorzugsweise um eine Zerkleinerungswalze, die besonders effektiv ist, wenn sie unmittelbar am Förderende des Förderbands angeordnet ist, denn dort kann sie auf einer Umlenkrolle des Förderbands aufliegen. Das kann die Umlenkrolle als solche sein oder aber auch das zwischen der Umlenkrolle und der Zerkleinerungswalze liegende Material des Förderbands. An dieser Stelle kann die Zerkleinerungswalze ohne besonderen Aufwand so ausgebildet sein, dass sie zwangsgefördert auf dem Band bzw. der Umlenkrolle mitläuft. Außerdem ist das Förderband im Bereich seiner Umlenkrolle am wenigsten flexibel, so dass die von der Zerkleinerungswalze auf den Streustoffteppich aufgebrachte Kraft vollständig für die Zerkleinerung des Streustoffteppichs zur Verfügung steht. Anstelle einer Zwangsförderung kann selbstverständlich auch ein Fremdantrieb für die Zerkleinerungswalze zweckmäßig sein. According to the invention is outside the grit container and before the end of delivery a conveyor belt shredder is provided on the conveyor belt. This is what it is about preferably a crushing roller, which is particularly effective when it is located directly at the end of the conveyor belt, because there it can rest on a pulley of the conveyor belt. The pulley can do that be such or that between the pulley and the Crushing roller lying material of the conveyor belt. At this point, the Shredding roller can be designed so that it without any special effort Forcibly conveyed runs on the belt or the pulley. Besides, that is Conveyor belt least flexible in the area of its pulley, so that of force of the shredding roller on the carpet of spreading material is available for shredding the scattering carpet. Instead of one Forced support can of course also be an external drive for the Crushing roller be useful.

Eine bevorzugte Ausführungsform der Zerkleinerungswalze besitzt in ihrer Mantelfläche liegende Zerkleinerungsstäbe, die sich beim Drehen der Zerkleinerungswalze in den Streustoffteppich eingraben und diesen aufbrechen. Um die auf einen Zerkleinerungsstab lastende Kraft zum Aufbrechen des Streustoffteppichs möglichst gering zu halten, sind die Zerkleinerungsstäbe in der Mantelfläche vorzugsweise schraubenförmig angeordnet. So wirkt immer nur ein kurzer Abschnitt des Zerkleinerungsstabs auf den Streustoffteppich ein. Dadurch ist es möglich, die Zerkleinerungsstäbe vergleichsweise schmal mit einer entsprechend günstigen Schnittwirkung auf das zu zerkleinernde Streugut auszubilden.A preferred embodiment of the comminution roller has in it Crushing rods lying on the lateral surface, which rotate when the Dig the crushing roller into the spreading carpet and break it open. To the force exerted on a shredding rod to break up the The shredding bars in the keep the spreading carpet as low as possible Shell surface preferably arranged helically. So only ever acts short section of the shredding rod onto the carpet of spreading material. Thereby it is possible to make the shredding rods comparatively narrow with one Correspondingly favorable cutting effect on the grit to be shredded train.

Nachfolgend wird die Erfindung beispielhaft anhand der begleitenden Zeichnungen beschrieben. Darin zeigen:

  • Figur 2 die Streuvorrichtung aus Figur 1 in Draufsicht,
  • Figur 3 einen vergrößerten Ausschnitt aus Figur 2,
  • Figur 4 eine besondere Ausführungsform einer Zerkleinerungswalze und
  • Figur 5 die Zerkleinerungswalze aus Figur 4 mit Befestigungsplatte und Abstreifer
    • The invention is described below by way of example with reference to the accompanying drawings. In it show:
  • FIG. 1 schematically shows a winter service vehicle with a spreading device,
  • FIG. 2 shows the spreading device from FIG. 1 in plan view,
  • FIG. 3 shows an enlarged detail from FIG. 2,
  • Figure 4 shows a particular embodiment of a crushing roller and
  • Figure 5 shows the shredding roller from Figure 4 with mounting plate and scraper

    • Figur 1 zeigt schematisch in Seitenansicht, stellvertretend für viele Arten von Trägerfahrzeugen und deren Aufbauten, ein Winterdienststreufahrzeug mit einer Ladefläche 2, auf dem ein Streustoffbehälter 1 aufliegt. Der Streustoffbehälter 1 ist in Figur 2 noch einmal in Draufsicht gezeigt. Er kann auch als Anhänger oder als fester Aufbau auf einen Chassis montiert sein. Die Seitenwände 9 des Behälters 1 laufen zum Behältergrund hin zusammen, an welchem sich ein Förderband 4 befindet. Das Förderband 4 läuft in Transportrichtung (Pfeilrichtung) unter einem in dem Behälter 1 befindlichen Salzstock weg und zieht dabei Salz ab. Das Salz wird durch eine Streustoffaustragöffnung 3 aus dem Behälter 1 hinausbefördert, wobei sich auf dem Förderband 4 außerhalb des Behälters 1 ein Streustoffteppich 11 ausbildet (Figur 3). Die Höhe und Breite des Streustoffteppichs 11 wird bestimmt durch den Öffnungsquerschnitt der Austragöffnung 3, dessen Höhe wiederum durch einen vertikal verlagerbaren Schieber 13 manuell einstellbar ist. Die pro Zeiteinheit geförderte Salzmenge wird durch die Transportgeschwindigkeit des Förderbands 4 definiert. Bei vorgegebener Streumenge pro Fahrbahnfläche hängt die Transportgeschwindigkeit des Förderbands 4 von der Weite der zu streuenden Fläche einerseits und der Fahrzeuggeschwindigkeit andererseits ab.Figure 1 shows schematically in side view, representative of many types of carrier vehicles and their superstructures, a winter service spreading vehicle with a loading area 2, on which a grit container 1 rests. The grit container 1 is in Figure 2 shown again in plan view. It can also be used as a trailer or as a fixed one Body mounted on a chassis. The side walls 9 of the container 1 converge towards the bottom of the container, on which a conveyor belt 4 is located. The conveyor belt 4 runs in the transport direction (arrow direction) under one in the salt dome located in container 1 and thereby draws off salt. The salt will conveyed out of the container 1 through a grit discharge opening 3, wherein there is a spreading material carpet 11 on the conveyor belt 4 outside the container 1 trains (Figure 3). The height and width of the scatter carpet 11 is determined through the opening cross section of the discharge opening 3, the height of which in turn is manually adjustable by a vertically displaceable slide 13. The pro The amount of salt extracted is determined by the transport speed of the Conveyor belt 4 defined. For a given spread rate per lane area hangs the transport speed of the conveyor belt 4 from the width of the to be spread Area on the one hand and the vehicle speed on the other.

    Der mit dem Förderband 4 geförderte Streustoff fällt vom Ende des Förderbands 4 in einen Trichter 8 und von dort auf einen Streustoffverteiler 7 in Form einer Schleuderscheibe bzw. eines Streutellers.The spreading material conveyed by the conveyor belt 4 falls from the end of the conveyor belt 4 into a funnel 8 and from there to a spreading material distributor 7 in the form of a Centrifugal disc or a spreading disc.

    Am in Transportrichtung des Förderbands 4 gelegenen Ende des Förderbands 4 ist ein Streustoffteppichzerkleinerer 5 nach Art einer Zerkleinerungswalze vorgsehen, um etwaig verklumptes Streumaterial aufzubrechen, bevor es in den Trichter 8 hinabfällt. Die Zerkleinerungswalze 5 liegt mit ihrer Drehachse senkrecht über und parallel zur Drehachse der Umlenkrolle 12 des Förderbands 4 und wird gegen die Umlenkrolle 12 bzw. das dazwischen liegende Förderband 4 angepresst, so dass die Walze 5 vom Förderband 4 zwangsgefördert mitläuft.At the end of the conveyor belt 4 located in the transport direction of the conveyor belt 4 a grit carpet shredder 5 in the manner of a shredding roller, in order to break up any lumped material before it enters the hopper 8 falls down. The crushing roller 5 lies with its axis of rotation perpendicular above and parallel to the axis of rotation of the deflection roller 12 of the conveyor belt 4 and is against the Deflection roller 12 or the intermediate conveyor belt 4 pressed so that the roller 5 is forcibly conveyed from the conveyor belt 4.

    Wie der Detailansicht in Figur 3 zu entnehmen ist, umfaßt die Zerkleinerungswalze 5 zwei Laufräder 10, zwischen denen der Streustoffteppich 11 hindurchläuft, sowie Zerkleinerungsstäbe 6, die zwischen den Laufrädern 10 schraubenförmig in der gedachten Mantelfläche der Walze 5 liegen. Die Walze 5 ist also im Grunde hohl mit einer zentralen Drehachse zur Stabilisierung der Zerkleinerungswalze. Durch diese Anordnung wird ein gleichmäßiges Aufbrechen des Streustoffteppichs 11 erreicht.As can be seen from the detailed view in FIG. 3, the Shredding roller 5 two impellers 10, between which the scattering carpet 11 passes through, and crushing rods 6, which between the impellers 10 lie helically in the imaginary surface of the roller 5. The roller 5 is basically hollow with a central axis of rotation to stabilize the Crushing drum. This arrangement ensures an even breakup of the scattering carpet 11 reached.

    Die schraubenförmig angeordneten Zerkleinerungsstäbe 6 müssen nicht notwendigerweise alle dieselbe Drehrichtung besitzen. Im Gegenteil ist es sogar für ein gleichmäßiges Aufbrechen des Streustoffteppichs 11 vorteilhaft, wenn sich einzelne Zerkleinerungsstäbe 6 in ihrer schraubförmigen Drehrichtung unterscheiden. Eine bevorzugte Ausführungsform, die in Fig. 4 gezeigt ist, sieht vor, dass sich die Zerkleinerungsstäbe 6 nicht über die gesamte Länge der Zerkleinerungswalze 5 erstrecken, sondern beispielsweise nur von jeder Seite der Zerkleinerungswalze 5 bis zu ihrer Mitte. In der Mitte und/oder an anderen Stellen der Zerkleinerungswalze 5 können auch weitere Laufräder 11 oder Stabilisierungsscheiben 14 zur Stabilisierung der Zerkleinerungsstäbe 6 vorgesehen sein.The shredding rods 6 arranged in a helical manner do not have to necessarily all have the same direction of rotation. On the contrary, it is advantageous for a uniform breakup of the scattering carpet 11, if individual shredding rods 6 in their screw-shaped direction of rotation differ. A preferred embodiment shown in FIG. 4 sees before that the shredding rods 6 are not over the entire length of the Crushing roller 5 extend, but for example only from each side of the Shredding roller 5 up to its center. In the middle and / or elsewhere the shredding roller 5 can also further wheels 11 or Stabilizing disks 14 for stabilizing the shredding rods 6 be provided.

    Die Zerkleinerungsstäbe 6 können unterschiedlichste Querschnitte besitzen. Sie können beispielsweise aus Rundstäben oder, wie in Fig. 4, aus Flachstahl hergestellt sein, wobei im letzteren Falle die Schmalseite des Flachstahls vorzugsweise radial von der Drehachse der Zerkleinerungswalze 5 wegweist, so dass die Zerkleinerungsstäbe 6 in den Streustoffteppich 11 von oben hineinschneiden.The shredding rods 6 can have a wide variety of cross sections. she can, for example, from round bars or, as in Fig. 4, from flat steel be produced, in the latter case the narrow side of the flat steel preferably pointing radially away from the axis of rotation of the comminution roller 5, so that the shredding rods 6 in the scattering carpet 11 from above cut into it.

    Ein weiterer Vorteil der schraubenförmigen Anordnung der Zerkleinerungsstäbe 6 ist darin zu sehen, dass ein Zerkleinerungsstab 6 nicht sogleich mit seiner gesamten Länge mit dem Streustoffteppich 11 in Eingriff kommt. Dies würde eine starke Belastung bedeuten und entsprechend stabilere und größere Zerkleinerungsstäbe 6 mit gegebenenfalls schlechteren Zerkleinerungsqualitäten erfordern.Another advantage of the helical arrangement of the comminution bars 6 can be seen in the fact that a shredding rod 6 does not immediately with his entire length comes into contact with the scattering carpet 11. This would be one heavy loads mean correspondingly more stable and larger Comminution bars 6 with possibly poorer comminution qualities require.

    Figur 5 zeigt die Zerkleinerungswalze 5 aus Fig. 4 mit einer Befestigungsplatte 15 zur Fixierung der Walze 5 an der Drehtelleraufhängung und mit einem sich über die gesamte Breite der Walze 5 erstreckenden Abstreifer 16, der die klebrige, zerkleinerte Masse vom Band abstreift, da sich ansonsten ein beträchtlicher Teil des Streusalzes am Förderband festsetzt. Die Konstanz des Streubildes kann damit wesentlich verbessert werden. FIG. 5 shows the comminution roller 5 from FIG. 4 with a fastening plate 15 to fix the roller 5 on the turntable suspension and with one over the entire width of the roller 5 extending stripper 16, the sticky, shredded mass from the belt, otherwise a considerable part of road salt on the conveyor belt. The constancy of the spread pattern can thus be significantly improved.
