Description

Die Erfindung betrifft einen Streustoffverteiler für Streufahrzeuge mit einem um eine Achse rotierbaren Streuelement und einer Zuführeinrichtung zum Zuführen eines Streustoffs sowie ein Streufahrzeug mit einem derartigen Streustoffverteiler.The invention relates to a scattering distributor for scattering vehicles with a rotatable about an axis scattering element and a feeder for supplying a scattering material and a scattering vehicle with such a scattering distributor.

Üblicherweise bestehen die Streustoffverteiler aus einem Streuteller, der mit Leitelementen versehen ist. Der Streustoff, beispielsweise Salz oder Splitt, wird an einer bestimmten Stelle dem rotierenden Streuteller zugeführt. Der Streustoff wird durch die Rotation des Streutellers nach außen geschleudert. Durch Veränderung des Abwurfpunktes an dem der Streustoff dem Streuteller zugeführt wird, lässt sich Positionierung des Streubilds in begrenztem Maße einstellen.Usually, the scattering agent distributors consist of a spreading plate, which is provided with guide elements. The scattering material, for example salt or grit, is fed at a certain point to the rotating spreading plate. The scattering material is thrown by the rotation of the spreading plate to the outside. By changing the discharge point at which the scattering material is supplied to the spreading plate, positioning of the scattering image can be adjusted to a limited extent.

Im Winterdienst wird das Salz meist zusammen mit einer Sole ausgebracht, um die Wirkung des Salzes zu verbessern. Dabei ergibt sich jedoch das Problem, dass das Gemisch aus Salz und Sole zu Verstopfungen im Bereich der Zuführeinrichtung neigt. Werden hingegen die beiden Bestandteile getrennt herangeführt und gemeinsam auf den Streuteller aufgebracht, findet keine ausreichende Durchmischung von Salz und Sole statt. Die eigentlichen Vorteile des Salz-Sole-Gemisches kommen dann nicht voll zum Tragen.In winter service, the salt is usually applied together with a brine to improve the effect of the salt. However, there is the problem that the mixture of salt and brine tends to blockages in the feeder. On the other hand, if the two components are introduced separately and applied together to the spreading plate, there is no adequate mixing of salt and brine. The actual advantages of the salt-brine mixture are then not fully effective.

Aus der US-A-3,419,221 ist ein Streustoffverteiler für Streufahrzeuge bekannt, der das Ausbringen von mehreren Streustoffen ermöglicht, ohne dass diese vorher vermischt werden. Dieser bekannte Streustoffverteiler weist eine um eine Achse angeordnete Kammer auf, wobei sich ein Streuelement radial außerhalb der Kammer anschließt. Die Kammer ist durch eine äußere Wandung und eine konzentrisch dazu angeordnete innere Wandung in einen inneren und einen äußeren Teilbereich unterteilt, wobei der innere Teilbereich zwei gegenüberliegende Öffnungen aufweist, die mit dem äußeren Teilbereich in Verbindung stehen und der äußere Teilbereich ebenfalls zwei gegenüberliegende Öffnungen aufweist, die den äußeren Teilbereich zum Streuelement öffnen. Über eine Zuführeinrichtung werden zwei unterschiedliche Stoffe dem inneren Teilbereich derart aufgegeben, dass der eine Stoff durch die eine Öffnung und der andere Stoff durch andere Öffnung in den äußeren Teilbereich gelangt, von wo sie über die beiden äußeren Öffnungen und das Streuelement ausgebracht werden.From the US-A-3,419,221 For example, a spreading material distributor for spreading vehicles is known, which makes it possible to dispense several scattering substances without these having to be mixed in advance. This known dispersing distributor has a chamber arranged around an axis, wherein a scattering element adjoins radially outside the chamber. The chamber is divided into an inner and an outer portion by an outer wall and an inner wall arranged concentrically therewith, wherein the inner portion has two opposite openings, which communicate with the outer portion and the outer portion also has two opposite openings, which open the outer portion of the scattering element. About a feeder are two different Substances placed the inner portion such that the material passes through the one opening and the other material through other opening in the outer portion, from where they are discharged through the two outer openings and the scattering element.

In der US-A-4,442,979 wird ein Streustoffverteiler beschrieben, bei dem zwei Streustoffe über konzentrisch ineinander angeordnete Zuführleitungen zentral auf einen Streuteller aufgegeben werden. Die Zuführleitungen sind im unteren Bereich im Querschnitt halbkreisförmig ausgebildet und weisen somit Öffnungen auf, die einen Winkelbereich von wenigstens 180° einnehmen. Der eine Stoff wird dabei über die innere Zuführleitung aufgegeben, während der andere Stoff über den Ringraum zwischen der inneren und äußeren Zuführleitung aufgebracht wird.In the US-A-4,442,979 a spreading material distributor is described, in which two scattering substances are placed centrally on a spreading plate via concentrically arranged feed lines. The supply lines are semicircular in cross section in the lower region and thus have openings which occupy an angular range of at least 180 °. The one substance is thereby fed via the inner feed line, while the other substance is applied via the annular space between the inner and outer feed line.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Streustoffverteiler für Streufahrzeuge anzugeben, mit dem das Ausbringen des Streustoffs verbessert werden kann.The invention is therefore based on the object of specifying a scattering distributor for scatter vehicles, with which the spreading of the scattering material can be improved.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale der Ansprüche 1 bzw. 7 gelöst.According to the invention this object is solved by the features of claims 1 and 7, respectively.

Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further embodiments of the invention are the subject of the dependent claims.

Der erfindungsgemäße Streustoffverteiler für Streufahrzeuge weist ein um eine Achse rotierbares Streuelement und eine Zuführeinrichtung zum Zuführen von wenigstens zwei unterschiedlichen Streustoffen auf, wobei die Zuführeinrichtung so ausgebildet ist, dass über eine erste Leitung der erste Streustoff und über eine zweite Leitung der zweite Streustoff zugeführt werden können.The scattering substance distributor according to the invention for spreading vehicles has a scattering element rotatable about an axis and a feeding device for feeding at least two different scattering substances, wherein the feeding device is designed so that the first scattering substance can be supplied via a first line and the second scattering material can be supplied via a second line ,

Weiterhin ist eine um die Achse angeordnete Kammer vorgesehen, wobei sich das Streuelement radial außerhalb der Kammer anschließt und die Kammer mit einer äußeren Wandung zum Streuelement abgegrenzt ist und rotierende Mitnehmerelemente sowie eine Öffnung in der äußeren Wandung.Furthermore, a chamber disposed about the axis is provided, wherein the scattering element connects radially outside the chamber and the chamber with a outer wall is delimited to the scattering element and rotating driver elements and an opening in the outer wall.

Die Kammer ist durch eine konzentrisch zur äußeren Wandung angeordnete innere Wandung in einen inneren Teilbereich und einen äußeren Teilbereich unterteilt,
wobei die beiden Teilbereich über eine Öffnung in der inneren Wandung miteinander in Verbindung stehen. Die Zuführeinrichtung ist derart angeordnet, dass die Streustoffe zunächst dem inneren Teilbereich der Kammer zugeführt werden können, die dann über die Öffnung der inneren Wandung in den äußeren Teilbereich und durch die Öffnung in den äußeren Wandung auf das Streuelement gelangen können. Weiterhin sind rotierende Mitnehmerelemente vorgesehen, die sowohl den inneren als auch den äußeren Teilbereich in einzelne Segmente unterteilen, wobei sich die beiden Streustoffe in den einzelnen Segmenten aufgrund der dort wirkenden Fliehkräfte durchdringen.The chamber is divided by an inner wall arranged concentrically with the outer wall into an inner partial area and an outer partial area,
wherein the two sub-area communicate with each other via an opening in the inner wall. The feeding device is arranged such that the scattering substances can first be supplied to the inner portion of the chamber, which can then reach the scattering element via the opening of the inner wall into the outer portion and through the opening in the outer wall. Furthermore, rotating driver elements are provided, which divide both the inner and the outer portion into individual segments, wherein the two scattering substances penetrate in the individual segments due to the centrifugal forces acting there.

Auf diese Weise besteht die Möglichkeit, dass das zugeführte Streugut über einen Winkelbereich von wenigstens 360° in der Kammer gehalten wird. Der erfindungsgemäße Streustoffverteiler zeichnet sich bei Zuführung von zwei unterschiedlichen Streustoffen (insbesondere Salz und Sole) durch eine gute Durchmischung und Durchdringung der beiden Streustoffe aus.In this way, there is the possibility that the supplied grit is held over an angular range of at least 360 ° in the chamber. The dispersing agent distributor according to the invention is distinguished by a good mixing and penetration of the two scattering substances when two different scattering substances (in particular salt and brine) are supplied.

Weiterhin ist ein Streufahrzeug mit einem derartigen Streustoffverteiler vorgesehen.Furthermore, a scattering vehicle is provided with such a scattering distributor.

In dem die Streustoffe zunächst dem inneren Teilbereich der Kammer zugeführt werden, kann die Verweilzeit deutlich erhöht werden, so dass beispielsweise bei der Aufgabe von Salz und Sole ausreichend Zeit besteht, damit die Sole das Salz durchdringt.In that the scattering materials are first supplied to the inner portion of the chamber, the residence time can be significantly increased, so that, for example, in the task of salt and brine enough time for the salt to penetrate the salt.

Gemäß einem bevorzugten Ausgestaltung ist die äußere Wandung der Kammer zylindrisch und feststehend ausgebildet.According to a preferred embodiment, the outer wall of the chamber is cylindrical and fixed.

Die Zuführeinrichtung wird vorzugsweise in Bezug auf die Öffnung in der äußeren Wandung derart angeordnet, dass der zugeführte Streustoff über einen Winkelbereich von wenigstens 180° in der Kammer gehalten wird. Eine besonders vorteilhafte Ausgestaltung besteht darin, dass man die äußere Wandung um die Achse verdreh- und arretierbar anordnet, da hierdurch das Streubild gezielt eingestellt werden kann. Bei den der Erfindung zugrundeliegenden Versuchen hat sich gezeigt, dass durch die äußere Wandung das Streubild wesentlich schärfer abgegrenzt wird, wodurch bis zu 20% des Streustoffs eingespart werden kann.The feed device is preferably arranged with respect to the opening in the outer wall such that the supplied scattering material is held over an angular range of at least 180 ° in the chamber. A particularly advantageous embodiment is that one rotatably and locks the outer wall about the axis, as a result, the scattering pattern can be adjusted specifically. In the experiments underlying the invention has been shown that by the outer wall, the spreading pattern is significantly sharper delimitation, whereby up to 20% of the scattering material can be saved.

Weitere Ausgestaltungen und Vorteile der Erfindung werden im folgenden anhand der beschreibung eines Ausführungsbeispiels und der Zeichnung näher erläutert.Further embodiments and advantages of the invention will be explained in more detail below with reference to the description of an embodiment and the drawing.

Die Figuren 1 bis 5 dienen zur Erläuterung der Wirkungsweise eines Streustoffverteilers. Die Figuren 6 bis 8 stellen den erfindungsgemäßen Streustoffverteiler dar. In Fig. 9 ist ein Streufahrzeug 100 mit einem am hinteren Ende des Fahrzeugs angebrachten Streustoffverteiler 101 dargestellt.The FIGS. 1 to 5 serve to explain the operation of a scattering distributor. The FIGS. 6 to 8 represent the scattering agent distributor according to the invention Fig. 9 1, a spreading vehicle 100 is shown having a dust dispenser 101 attached to the rear end of the vehicle.

Anhand der Fig. 1 bis 4 wird zunächst ein Streustoffverteiler für Streufahrzeuge näher erläutert. Der Streustoffverteiler besteht im wesentlichen aus einem um eine Achse 1 rotierbaren Streuelement 2 (Drehrichtung 11), einer Zuführeinrichtung 3 zum Zuführen wenigstens eines Streustoffs 4 sowie einer um die Achse angeordnete Kammer 5, wobei sich das Streuelement 2 radial außerhalb der Kammer anschließt und die Kammer mit einer äußeren Wandung 5a zum Streuelement abgrenzt ist. Die Kammer 5 weist ferner rotierende Mitnehmerelemente 6 sowie eine Öffnung 5b in der äußeren Wandung 5a auf.Based on Fig. 1 to 4 First, a scattering distributor for gritter vehicles will be explained in more detail. The scattering agent distributor consists essentially of a rotatable about an axis 1 scattering element 2 (rotational direction 11), a feed device 3 for supplying at least one scattering material 4 and a arranged about the axis of the chamber 5, wherein the scattering element 2 connects radially outside the chamber and the chamber is delimited with an outer wall 5a to the scattering element. The chamber 5 also has rotating driver elements 6 and an opening 5b in the outer wall 5a.

Das Streuelement 2 ist mit Leitelementen 7 versehen, die im dargestellten Ausführungsbeispiel radial angeordnet sind.The scattering element 2 is provided with guide elements 7, which are arranged radially in the illustrated embodiment.

Die äußere Wandung 5a ist während des Betriebes feststehend ausgebildet. Die rotierenden Mitnehmerelemente 6 sind radial angeordnet und erstrecken sich von der Achse 1 bis zur äußeren Wandung 5a, so dass die Kammer in einzelne Segmente unterteilt wird.The outer wall 5a is fixed during operation. The rotating driver elements 6 are arranged radially and extend from the axis 1 to the outer wall 5a, so that the chamber is divided into individual segments.

Im dargestellten Streustoffverteiler sind neben der äußeren Wandung 5a auch der Boden 5c der Kammer 5 während des Betriebes feststehend ausgebildet, während sich das Streuelement 2 mit seinen Leitelementen 7 und die Mitnehmerelemente 6 in der Kammer um die Achse 1 rotieren.In the scattering substance distributor shown in addition to the outer wall 5a and the bottom 5c of the chamber 5 are fixed during operation, while the scattering element 2 rotate with its guide elements 7 and the driver elements 6 in the chamber about the axis 1.

Es ist selbstverständlich auch möglich, dass lediglich die Wandung 5a feststehend ausgebildet ist, während der Boden 5c mitrotiert. In diesem Fall würde man zweckmäßigerweise den Boden 5c und das Streuelement als eine durchgehende Scheibe ausbilden. Es wäre aber auch denkbar, dass man das Streuelement als Scheibe ausbildet, die unmittelbar unterhalb der Kammer 5 angeordnet ist und im Durchmesser entsprechend größer ausgebildet ist, so dass sich eine ähnliche Draufsicht wie in Fig. 1 ergibt.It is of course also possible that only the wall 5a is fixed, while the bottom 5c rotates. In this case, it would be expedient to form the bottom 5c and the scattering element as a continuous disk. It would also be conceivable that the scattering element as Disc forms, which is arranged immediately below the chamber 5 and is formed correspondingly larger in diameter, so that a similar plan view as in Fig. 1 results.

Im dargestellten Streustofferteiler ist die Zuführeinrichtung 3 so ausgebildet, dass über eine erste Leitung 3a der erste Streustoff 4 und über eine zweite Leitung 3b ein zweiter Streustoff 4a zugeführt werden können. Bei dem ersten Streustoff handelt es sich zum Beispiel um Salz und beim zweiten Streustoff 4a um eine Sole.In the dispenser shown, the feeder 3 is formed so that a first line 3a, the first scattering material 4 and a second line 3b, a second scattering material 4a can be supplied. For example, the first scattering substance is salt and the second scattering substance 4a is a brine.

Wie insbesondere aus Fig. 1 ersichtlich wird, ist die Streueinrichtung derart angeordnet, dass der bzw. die Streustoffe zunächst der Kammer 5 zugeführt werden, wobei die Aufgabenstelle radial innen, d.h. in der Nähe der Achse 1, vorgesehen ist. Das Streugut wird dann über die Mitnehmer 6 um die Achse 1 transportiert, wobei es durch die Fliehkraft an die äußere Wandung 5a gedrückt wird. Sobald die Öffnung 5b erreicht ist, gelangt der Streustoff auf das Streuelement und wird mittels der Leitelemente 7 verstreut.As in particular from Fig. 1 it can be seen, the scattering device is arranged such that the or the scattering materials are first supplied to the chamber 5, wherein the task point is provided radially inward, ie in the vicinity of the axis 1. The grit is then transported over the driver 6 about the axis 1, wherein it is pressed by the centrifugal force to the outer wall 5a. As soon as the opening 5b is reached, the scattering substance reaches the scattering element and is scattered by means of the guide elements 7.

Die Zuführeinrichtung 3 ist gegenüber der Öffnung 5b derart angeordnet, so dass das Streugut zunächst über einen Winkelbereich von wenigstens 180° in der Kammer transportiert wird. Durch die dort wirkenden Fliehkräfte besteht insbesondere bei Aufgabe von zwei Streustoffen die Möglichkeit, dass sich diese durchdringen. Dies hat sich insbesondere bei Zugabe von Salz und Sole als besonders wirkungsvoll erwiesen.The feed device 3 is arranged opposite to the opening 5b, so that the grit is first transported over an angular range of at least 180 ° in the chamber. Due to the centrifugal forces acting there, there is the possibility that these penetrate especially when two stray substances are dispensed with. This has proven to be particularly effective especially with the addition of salt and brine.

Fig. 4 zeigt ein Streubild 8, welches sich bei einer bestimmten Ausrichtung der Öffnung 5b im Bezug auf die Fahrtrichtung 9 des Fahrzeuges und die Drehrichtung 11 des Streuelements ergibt. Durch Verdrehen der Wandung 5a in Richtung des Doppelpfeils 10 kann das Streubild gezielt an die jeweilige Situation angepasst werden. Fig. 4 shows a scattering pattern 8, which results in a specific orientation of the opening 5b with respect to the direction of travel 9 of the vehicle and the direction of rotation 11 of the scattering element. By rotating the wall 5 a in the direction of the double arrow 10, the scattering pattern can be adapted specifically to the respective situation.

Fig. 5 zeigt ein Streubild 8', welches sich durch Verstellung der Wandung 5a ergeben hat. Fig. 5 shows a scattering pattern 8 ', which has resulted by adjusting the wall 5a.

Die äußere Wandung 5a der Kammer ermöglicht somit eine sehr einfache Positionierung des Streubildes. Der obenbeschriebene Streustoffverteiler zeichnet sich darüber hinaus dadurch aus, dass sich die seitlichen Grenzen 8a, 8b bzw. 8'a, 8'b der Streubilder 8 bzw. 8' sehr deutlich abzeichnen. Der Anteil des Streustoffs, der über die gewünschten Bereiche hinaus verstreut wird, ist bei dem obenbeschriebenen Streustoffverteiler relativ gering, so dass gegenüber herkömmlichen Streustoffverteiler bis zu 20% Streustoff eingespart werden kann.The outer wall 5a of the chamber thus enables a very simple positioning of the scattering pattern. The above-described spreading material distributor is also characterized by the fact that the lateral boundaries 8a, 8b and 8'a, 8'b of the scattering patterns 8 and 8 'are very clearly visible. The proportion of the scattering substance that is scattered beyond the desired ranges is relatively low in the above-described scattering agent distributor, so that compared to conventional scattering agent distributors, up to 20% of scattering material can be saved.

Im folgenden wird anhand der Fig. 6-8 ein erfindungsgemäßes Ausführungsbeispiel eines Streustoffverteilers für Streufahrzeuge beschrieben. Es werden dabei für gleiche Bauteile die selben Bezugszeichen wie im Ausführungsbeispiel gemäß der Fig. 1 bis 5 verwendet.The following is based on the Fig. 6-8 an inventive embodiment of a scattering distributor for spreading vehicles described. There are the same reference numerals for the same components as in the embodiment according to the Fig. 1 to 5 used.

Der Unterschied zum oben beschriebenen Streustoffverteiler besteht insbesondere darin, dass die Kammer 5 durch eine konzentrisch zur äußeren Wandung 5a angeordnete innere Wandung 5d in einen inneren Teilbereich und einen äußeren Teilbereich unterteilt ist, wobei die beiden Teilbereiche über eine Öffnung 5e in der inneren Wandung 5d miteinander in Verbindung stehen. Sowohl die äußere Wandung 5a als auch die innere Wandung 5d sind während des Betriebes feststehend angeordnet, so dass der Transport des Streustoffs durch die rotierenden Mitnehmerelemente 6 erfolgt, die sich radial nach außen sowohl über den inneren als auch über den äußeren Teilbereich erstrecken, wie insbesondere aus Fig. 7 ersichtlich wird.The difference from the above-described dispersing agent distributor is in particular that the chamber 5 is subdivided into an inner subregion and an outer subregion by an inner wall 5d arranged concentrically with the outer wall 5a, wherein the two subregions communicate with each other via an opening 5e in the inner wall 5d keep in touch. Both the outer wall 5a and the inner wall 5d are stationary during operation, so that the transport of the scattering material by the rotating driver elements 6, which extend radially outwardly over both the inner and on the outer portion, in particular out Fig. 7 becomes apparent.

Der Vorteil dieser weiteren Unterteilung besteht vor allem darin, dass die Verweilzeit des Streustoffs bzw. der Streustoffe weiter erhöht werden kann, da die Streustoffe über einen Winkelbereich von wenigstens 360° in der Kammer 5 verbleiben können.The advantage of this further subdivision is, above all, that the residence time of the scattering substance or of the scattering substances can be further increased, since the scattering substances can remain in the chamber 5 over an angular range of at least 360 °.

Die Mitnehmerelemente 6 unterteilen sowohl den inneren als auch den äußeren Teilbereich in einzelne Segmente. Die Zuführeinrichtung 3 ist so angeordnet, dass die Streustoffe im Bereich eines Segments im inneren Teilbereich zugeführt werden. Aufgrund der Fliehkraft werden die Streustoffe in den einzelnen Segmenten nach außen gegen die Wandung 5d gedrückt und über einen Winkelbereich α bis zur Öffnung 5e weitertransportiert, wo sie in einen segmentartigen Abschnitt im äußeren Teilbereich gelangen und über einen weiteren Winkelbereich β bis zur Öffnung 5b in der äußeren Wandung 5a transportiert werden. Dort erreicht der Streustoff das rotierende Streuelement 7 und wird durch die Leitelemente 7 verstreut. Die Einstellung des Streubildes erfolgt wiederum durch Verdrehen der äußeren Wandung 5a um die Achse 1. Die innere Wandung 5d kann dabei entweder zusammen mit der äußeren Wandung 5a oder separat von dieser verdreht und arretiert werden. Im Rahmen der Erfindung wäre es selbstverständlich auch denkbar, wenn man die Kammer durch entsprechende Wandungen im weitere Teilbereiche unterteilt.The driver elements 6 divide both the inner and the outer portion into individual segments. The feed device 3 is arranged so that the scattering substances are supplied in the region of a segment in the inner portion. Due to the centrifugal force, the scattering substances are pressed in the individual segments outwardly against the wall 5d and transported over an angular range α to the opening 5e, where they enter a segment-like section in the outer portion and over a wider angular range β to the opening 5b in the outer wall 5a are transported. There, the scattering substance reaches the rotating scattering element 7 and is scattered by the guide elements 7. The adjustment of the scattering pattern is in turn carried out by turning the outer wall 5a about the axis 1. The inner wall 5d can either be rotated and locked together with the outer wall 5a or separately from this. Within the scope of the invention, it would of course also be conceivable if the chamber is subdivided by corresponding walls in the further subregions.

Für das Streuelement 2 und die Mitnehmerelemente 6 kann entweder ein gemeinsamer oder separate Antriebe vorgesehen werden, die in herkömmlicherweise in ihrer Geschwindigkeit regelbar sind.For the scattering element 2 and the entrainment elements 6, either a common or separate drives can be provided, which are conventionally adjustable in their speed.

Der erfindungsgemäße Streustoffverteiler zeichnet sich insbesondere bei der Zuführung von zwei unterschiedlichen Streustoffen, insbesondere Salz und Sole, durch eine gute Durchmischung und Durchdringung der beiden Streustoffe aus. Ein weiterer Vorteil des Streustoffverteilers besteht in der Erzeugung eines scharf abgegrenzten Streubildes und der einfachen Möglichkeit zur Verstellung des Streubildes aus. Dadurch ist es möglich, dass den Streustoff gezielt auf die gewünschten Bereiche auszubringen, wodurch gegenüber herkömmlichen Streustoffverteilern bis 20% Streustoff eingespart werden kann.The scattering substance distributor according to the invention is characterized in particular by the supply of two different scattering substances, in particular salt and brine, by a thorough mixing and penetration of the two scattering substances. A further advantage of the scattering agent distributor is the production of a sharply delimited spreading pattern and the simple possibility of adjusting the spreading pattern. As a result, it is possible to deliberately apply the scattering material to the desired areas, whereby up to 20% of scattering material can be saved in comparison to conventional scattering substance distributors.
