Definitions
- the invention relates to a dispensing device for a liquid and a winter service vehicle with such a dispensing device.
- the liquid dispensing device of interest here has a dispensing element rotating in one direction of rotation and a nozzle arrangement for applying the liquid to the rotating dispensing element.
- a typical field of application for such an application device is winter service.
- the rotating Ausbringelement is designed as a spreading plate for spreading road salt and / or brine.
- Such a scattering device is for example from the DE 10 2007 031 880 A1 known.
- the liquid in the form of brine is used on the one hand to moisten the road salt to achieve a faster thawing result and on the other hand to prevent drift.
- weather and road conditions e.g. in freezing wet conditions, where only the brine is discharged.
- jet nozzles and high-pressure nozzles are nowadays used in particular, but they represent a risk of collision in oncoming traffic. If the brine is spread over a rotating spreading disc, however, usually only one additional lane can be satisfactorily covered. If, for example, a parking bay is to be sprinkled and the vehicle drives into this parking bay, the result over the entire roadway width is no longer satisfactory.
- the dispensing device for a liquid substance has a dispensing element rotating in one direction of rotation and a nozzle arrangement for applying the liquid to the rotating dispensing element, wherein the nozzle arrangement provides at least a first nozzle outlet opening, which in the plan view is at an angle of 90 ° +/- 30 Is aligned with the radial direction of the rotating Ausbringelements and the other is aligned in the direction of rotation of the rotating Ausbringelements parallel to the rotating Ausbringelement or in the rotational direction of the rotating Ausbringelements obliquely on the rotating Ausbringelement.
- the liquid to be dispensed experiences an acceleration in the desired dispensing direction as a result of the rotation of the dispensing element and is also applied to the rotating dispensing element with a corresponding (pre-) impulse in the desired direction.
- the inventive solution significantly greater ranges.
- an asymmetrical spreading pattern is meant a wetting of the roadway behind the vehicle and an increased coverage of the lane or lanes on one side of the vehicle.
- an angle ⁇ to the rotating Ausbringelement 4 to understand which is smaller than 90 ° and maximum parallel to rotating dispensing element 4 is aligned.
- the deployment angle is 85 °> ⁇ ⁇ 0 °, most preferably 70 °> ⁇ > 20 °.
- the rotating dispensing element is formed by a rotating spreading plate, which is expediently equipped on its upper side with distributing elements distributed over its circumference, which divide the dispensing element into ring segments.
- the radially inner ends of the distributor elements are preferably formed bevelled, whereby the introduction of the liquid is facilitated in the individual ring segments.
- the nozzle arrangement is preferably curved in the direction of rotation of the rotating dispensing element, in particular extending over an angular range of 10 ° ⁇ ⁇ 270 °, most preferably 30 ° ⁇ ⁇ 180 °, in the direction of rotation of the rotating dispensing element. Furthermore, it is advantageous if the nozzle arrangement is arranged stationary relative to the rotating dispensing element, whereby the supply of the liquid material is simplified.
- the first nozzle outlet opening is - in plan view - preferably aligned at an angle of 90 ° +/- 20 ° to the radial direction of the rotating Ausbringelements.
- the nozzle arrangement has at least one second nozzle outlet opening, preferably a third and / or fourth nozzle outlet opening, which are arranged at a distance from the first nozzle outlet opening in the rotational direction behind the first nozzle outlet opening and which are aligned in the direction of rotation of the rotating Ausbringelements obliquely on the rotating Ausbringelement.
- the nozzle arrangement is in operative connection with a conveying device for the liquid substance, in particular a pump.
- a feed device for applying a solid to the rotating dispensing element can furthermore be provided.
- a feeder is formed, for example, in a conventional manner by a chute through which the solid, for example salt, is placed on the rotating dispensing element.
- Vehicle 1 shown is, for example, a winter service vehicle that has an application device 2 for discharging a liquid, in particular sols, and / or a solid, in particular salt. It consists essentially of a rotating in a rotational direction 3 Ausbringelement 4 and a nozzle assembly 5 for applying the liquid to the rotating Ausbringelement 4.

- a solid fuel tank 8 is arranged on the vehicle 1 in order to apply a solid to the rotating discharge element 4 via a solids channel 9.
- the dispensing device 2 is dimensioned and adjusted so that an asymmetrical spreading pattern according to Fig.2 results. This means that not only the lane 10 used by the vehicle 1 is covered with the scattering means, but at least also a lane 11 arranged laterally thereof is covered. In this way, the scattering agent to be applied can be distributed with a drive over at least two lanes 10, 11.
- the rotating dispensing element 4 is designed in particular as a spreading plate and rotates about an axis of rotation oriented substantially vertically to the bottom 12.
- distributor elements 41 are provided which divide the Ausbringelement 4 into ring segments.
- the distributor elements 41 are formed schaufelförmig in Pictured embodiment and extend from the outer edge in the radial direction approximately to the middle of Ausbringelements 4.

- the distributor elements 41 are also fixedly connected to the discharge element 4 and thus rotate about the axis of rotation 12. Spreaders in the form of a liquid or a solid applied to the discharge element 4 are accelerated by means of the distributor elements 41 and applied. There are not shown here covers (protective covers) are provided.
- the solid material For discharging the solid material, it is applied to the rotating discharge element 4 via the solids channel 9 in a middle region. As a result of the rotational movement and the centrifugal force acting on the solid, the solid reaches between the distributor elements and is carried by these over the outer edge of the dispensing element to the outside.

These arrows thus also represent the outlet direction of the nozzle outlet openings. As can be seen in particular from Fig.
- the oblique orientation is to be understood as meaning an angle ⁇ to the rotating dispensing element 4 which is aligned smaller than 90 ° and maximally parallel to the rotating dispensing element 4.
- the deployment angle is 85 °> ⁇ ⁇ 0 °, most preferably 70 °> ⁇ > 20 °.
- the nozzle arrangement 5 is located above an inlet opening 59 (FIG. Fig. 6 ) with the supply line 6 for the liquid in combination.

Description
Die Erfindung betrifft eine Ausbringvorrichtung für einen Flüssigstoff sowie ein Winterdienst-Fahrzeug mit einer solchen Ausbringeinrichtung.The invention relates to a dispensing device for a liquid and a winter service vehicle with such a dispensing device.
Die hier interessierende Ausbringvorrichtung für einen Flüssigstoff weist ein in einer Drehrichtung rotierendes Ausbringelement und eine Düsenanordnung zum Aufbringen des Flüssigstoffs auf das rotierende Ausbringelement auf Ein typisches Anwendungsgebiet für eine derartige Ausbringvorrichtung ist der Winterdienst. Dort ist das rotierende Ausbringelement als Streuteller zum Ausbringen von Streusalz und/oder Sole ausgebildet. Eine derartige Streuvorrichtung ist beispielsweise aus der
Den Flüssigstoff in Form von Sole nutzt man einerseits zum Anfeuchten des Streusalzes, um ein schnelleres Auftauergebnis zu erreichen und andererseits um einer Verwehung vorzubeugen. Es gibt aber auch Witterungs- und Fahrbahnverhältnisse, z.B. bei überfrierender Nässe, bei denen lediglich die Sole ausgetragen wird. Um Sole mit einer Streubreite von 6 m und mehr über die Fahrbahn zu verteilen, kommen heutzutage insbesondere Düsenbalken und Hochdruckdüsen zum Einsatz, die aber bei Gegenverkehr eine Kollisionsgefahr darstellen. Wird die Sole über einen rotierenden Streuteller ausgebracht, kann aber meist nur noch ein zusätzlicher Fahrstreifen in zufriedenstellender Weise abgedeckt werden. Soll beispielsweise auch eine Parkbucht bestreut werden und fährt das Fahrzeug in diese Parkbucht hinein, ist das Ergebnis über die gesamte Fahrbahnbreite nicht mehr befriedigend.The liquid in the form of brine is used on the one hand to moisten the road salt to achieve a faster thawing result and on the other hand to prevent drift. However, there are also weather and road conditions, e.g. in freezing wet conditions, where only the brine is discharged. In order to distribute brine with a spreading width of 6 m and more over the roadway, jet nozzles and high-pressure nozzles are nowadays used in particular, but they represent a risk of collision in oncoming traffic. If the brine is spread over a rotating spreading disc, however, usually only one additional lane can be satisfactorily covered. If, for example, a parking bay is to be sprinkled and the vehicle drives into this parking bay, the result over the entire roadway width is no longer satisfactory.
Aus der
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of
Die erfindungsgemäße Ausbringvorrichtung für einen Flüssigstoff weist ein in einer Drehrichtung rotierendes Ausbringelement und eine Düsenanordnung zum Aufbringen des Flüssigstoffs auf das rotierende Ausbringelement auf, wobei die Düsenanordnung wenigstens eine erste Düsenauslassöffnung vorsieht, die einerseits in der Draufsicht in einem Winkel von 90° +/- 30° zur radialen Richtung des rotierenden Ausbringelements ausgerichtet ist und die andererseits in Drehrichtung des rotierenden Ausbringelements parallel zum drehenden Ausbringelement oder in Drehrichtung des rotierenden Ausbringelements schräg auf das rotierende Ausbringelement ausgerichtet ist.The dispensing device according to the invention for a liquid substance has a dispensing element rotating in one direction of rotation and a nozzle arrangement for applying the liquid to the rotating dispensing element, wherein the nozzle arrangement provides at least a first nozzle outlet opening, which in the plan view is at an angle of 90 ° +/- 30 Is aligned with the radial direction of the rotating Ausbringelements and the other is aligned in the direction of rotation of the rotating Ausbringelements parallel to the rotating Ausbringelement or in the rotational direction of the rotating Ausbringelements obliquely on the rotating Ausbringelement.
Der auszubringende Flüssigstoff erfährt zum einen durch die Rotation des Ausbringelements eine Beschleunigung in die gewünschte Ausbringrichtung und wird zudem mit einem entsprechenden (Vor-)Impuls in die gewünschte Richtung auf das rotierende Aufbringelement aufgegeben. Gegenüber den herkömmlichen Lösungen, bei denen der Flüssigstoff senkrecht von oben auf das rotierende Ausbringelement aufgegeben wird, lassen sich mit der erfindungsgemäßen Lösung erheblich größere Reichweiten realisieren. Bei den der Erfindung zugrunde liegenden Versuchen konnte einen Streuweite bei einem asymmetrischen Streubild von bis zu 10 m und mehr erreicht werden.On the one hand, the liquid to be dispensed experiences an acceleration in the desired dispensing direction as a result of the rotation of the dispensing element and is also applied to the rotating dispensing element with a corresponding (pre-) impulse in the desired direction. Compared to the conventional solutions, in which the liquid is fed vertically from above onto the rotating dispensing element, can be realized with the inventive solution significantly greater ranges. In the experiments on which the invention is based, it was possible to achieve a scattering width with an asymmetrical scattering pattern of up to 10 m and more.
Unter einem asymmetrischen Streubild ist eine Benetzung der Fahrbahn hinter dem Fahrzeug sowie eine vermehrte Abdeckung des oder der Fahrstreifen auf einer Seite des Fahrzeugs gemeint.By an asymmetrical spreading pattern is meant a wetting of the roadway behind the vehicle and an increased coverage of the lane or lanes on one side of the vehicle.
Unter der schrägen Ausrichtung ist erfindungsgemäß ein Winkel β zum rotierenden Ausbringelement 4 zu verstehen, der kleiner als 90° und maximal parallel zum rotierenden Ausbringelement 4 ausgerichtet ist. Vorzugsweise beträgt der Ausbringwinkel 85° > β ≥ 0°, höchstvorzugsweise 70° > β > 20°.Under the oblique orientation is according to the invention an angle β to the
Bei herkömmlichen Düsenanordnungen wird der Flüssigstoff senkrecht von oben auf das Ausbringelement aufgebracht. Bei den der Erfindung zugrunde liegenden Versuchen hat sich jedoch gezeigt, dass diese Art der Aufbringung zu einer Zerstäubung des Flüssigstoffs führt, was eine begrenzte seitliche Reichweite zur Folge hat.In conventional nozzle arrangements, the liquid is applied vertically from above onto the dispensing element. In the experiments on which the invention is based, however, it has been shown that this type of application leads to an atomization of the liquid substance, which results in a limited lateral range.
Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further embodiments of the invention are the subject of the dependent claims.
Gemäß einer bevorzugten Ausgestaltung der Erfindung wird das rotierende Ausbringelement durch einen rotierenden Streuteller gebildet, der auf seiner Oberseite zweckmäßigerweise mit über seinem Umfang verteilt angeordneten Verteilerelementen ausgestattet ist, die das Ausbringelement in Ringsegmente unterteilen. Die radial innen liegenden Enden der Verteilerelemente sind dabei vorzugsweise abgeschrägt ausgebildet, wodurch das Einbringen des Flüssigstoffs in die einzelnen Ringsegmente erleichtert wird.According to a preferred embodiment of the invention, the rotating dispensing element is formed by a rotating spreading plate, which is expediently equipped on its upper side with distributing elements distributed over its circumference, which divide the dispensing element into ring segments. The radially inner ends of the distributor elements are preferably formed bevelled, whereby the introduction of the liquid is facilitated in the individual ring segments.
Die Düsenanordnung ist vorzugsweise in Drehrichtung des rotierenden Ausbringelements gekrümmt ausgebildet, wobei sie sich insbesondere über einen Winkelbereich von 10° < α < 270°, höchstvorzugsweise von 30° < α < 180°, in Drehrichtung des rotierenden Ausbringelements erstreckt. Des Weiteren ist es von Vorteil, wenn die Düsenanordnung gegenüber dem rotierenden Ausbringelement feststehend angeordnet ist, wodurch sich die Zuführung des Flüssigstoffs vereinfacht. Die erste Düsenauslassöffnung ist - in der Draufsicht - vorzugsweise in einem Winkel von 90° +/- 20° zur radialen Richtung des rotierenden Ausbringelements ausgerichtet. Ist die Ausbringvorrichtung am hinteren Ende eines Winterdienstfahrzeuges angebracht, ist die Ausbringrichtung der ersten Düsenauslassöffnung "von oben betrachtet" schräg zur Seite und hinten ausgerichtet.The nozzle arrangement is preferably curved in the direction of rotation of the rotating dispensing element, in particular extending over an angular range of 10 ° <α <270 °, most preferably 30 ° <α <180 °, in the direction of rotation of the rotating dispensing element. Furthermore, it is advantageous if the nozzle arrangement is arranged stationary relative to the rotating dispensing element, whereby the supply of the liquid material is simplified. The first nozzle outlet opening is - in plan view - preferably aligned at an angle of 90 ° +/- 20 ° to the radial direction of the rotating Ausbringelements. When the dispenser is attached to the rear end of a winter utility vehicle, the discharge direction of the first nozzle outlet port is "obliquely side-facing" as viewed from above.
Gemäß einer besonderen Ausgestaltung der Erfindung weist die Düsenanordnung wenigstens eine zweite Düsenauslassöffnung, vorzugsweise eine dritte und/oder vierte Düsenauslassöffnung, auf, die mit Abstand zur ersten Düsenauslassöffnung in Drehrichtung hinter der ersten Düsenauslassöffnung angeordnet sind und die in Drehrichtung des rotierenden Ausbringelements schräg auf das rotierende Ausbringelement ausgerichtet sind. Auf diese Weise kann gleichzeitig eine größere Menge des Flüssigstoffs über einen vorgegebenen Winkelbereich auf das Ausbringelement aufgebracht werden. Damit der Flüssigstoff die Düsenanordnung mit einem Vorimpuls verlässt, steht die Düsenanordnung mit einer Fördereinrichtung für den Flüssigstoff, insbesondere einer Pumpe, in Wirkverbindung.According to a particular embodiment of the invention, the nozzle arrangement has at least one second nozzle outlet opening, preferably a third and / or fourth nozzle outlet opening, which are arranged at a distance from the first nozzle outlet opening in the rotational direction behind the first nozzle outlet opening and which are aligned in the direction of rotation of the rotating Ausbringelements obliquely on the rotating Ausbringelement. In this way, at the same time a larger amount of the liquid can be applied to the dispensing element over a predetermined angular range. So that the liquid substance leaves the nozzle arrangement with a pre-pulse, the nozzle arrangement is in operative connection with a conveying device for the liquid substance, in particular a pump.
Neben der Düsenanordnung zum Aufbringen des Flüssigstoffs kann weiterhin eine Aufgabevorrichtung zum Aufbringen eines Feststoffs auf das rotierende Ausbringelement vorgesehen werden. Eine solche Aufgabevorrichtung wird beispielsweise in herkömmlicher Art und Weise durch eine Schütte gebildet, über die der Feststoff, beispielsweise Salz, auf das rotierende Ausbringelement gebracht wird.In addition to the nozzle arrangement for applying the liquid substance, a feed device for applying a solid to the rotating dispensing element can furthermore be provided. Such a feeder is formed, for example, in a conventional manner by a chute through which the solid, for example salt, is placed on the rotating dispensing element.
