Description

Vorrichtung zum Vernichten von unerwünschtem Pflanzenwuchs im Bereich von FahrwegenDevice for destroying unwanted vegetation in the area of driveways
Die Erfindung betrifft eine Vorrichtung zum Vernichten von unerwünschtem Pflanzenwuchs im Bereich von Fahrwegen, insbesondere auf Gleisbetten, mit einem Fahrzeug, insbe¬ sondere Schienenfahrzeug, auf welchem ein Dampferzeugungs- aggregat montiert ist, an dessen Dampfausgang Dampfdüsen angeschlossen sind, die zumindest einen quer zur Fahrtrich¬ tung im wesentlichen über die Fahrwegbreite verlaufenden Düsenbalken bilden, der unterhalb des Fahrgestells des Fahrzeuges mittels eines höhenverstellbaren Trägers montiert ist, wobei ferner um eine in Fahrtrichtung verlaufende Achse verschwenkbare seitliche Trägerteile mit Düsenbalkenabschnitten vorgesehen sind, die in Verlängerung des Düsenbalkens verlaufen.The invention relates to a device for destroying unwanted vegetation in the area of roadways, in particular on track beds, with a vehicle, in particular a rail vehicle, on which a steam generating unit is mounted, to the steam outlet of which steam nozzles are connected, at least one of which is transverse to the driving direction ¬ device form substantially over the travel path width, the nozzle bar, which is mounted below the chassis of the vehicle by means of a height-adjustable bracket, furthermore, lateral beam parts with nozzle bar sections are provided which are pivotable about an axis running in the direction of travel and extend in the extension of the nozzle bar.
Bisher wird unerwünschter Pflanzenwuchs z.B. auf Gleisbetten üblicherweise mittels Chemikalien vernichtet. Das zunehmende Umweltbewußtsein hat eine verstärkte Sensibilisierung gegenüber chemischen Vernichtungsmitteln zur Folge, weil selbst sogenannte "umweltfreundliche" Mittel nicht nur den Pflanzenwuchs beseitigen, sondern auch das biologische Gleichgewicht des Bodens empfindlic stören und das Grundwasser verseuchen.So far, undesirable plant growth e.g. on track beds usually destroyed by chemicals. Increasing environmental awareness has led to increased sensitization to chemical destructive agents, because even so-called "environmentally friendly" agents not only eliminate plant growth, but also seriously disturb the biological balance of the soil and contaminate the groundwater.
Aus der US-PS 1 238 861 ist es bereits bekannt, eine Dampflokomotive an der Unterseite ihres Fahrgestells mit einem das Gleis überspannenden höhenverstellbaren Träger für dampfführende Rohre auszustatten, aus denen über Düsen Dampf gegen das Schotterbett gesprüht werden kann. Der sich in Längsrichtung des Fahrgestells erstreckende Träger ist höhenverstellbar und außerhalb der Schienen mit zwei angelenkten, ebenfalls Dampfrohre tragenden Seitenteilen versehen, welche die Seitenabschnitte des Schotterbettes überstreichen. Die bekannte Ausführung ist konstruktiv infolge der Vielzahl von Dampftlüsenrohren, welche über die gesamte Fläche des Trägers verteilt sind, relativ aufwendig und wegen des nach allen Seiten relativ unbehinderten Dampfaustrittes leistungsschwach. Die Erfindung zielt darauf ab, eine Vorrichtung der einleitend angegebenen Art zu schaffen, welche bei effi¬ zienter Vernichtungswirkung durch Verwendung von Wasser¬ dampf eine ausgezeichnete Umweltverträglichkeit bietet, d.h. weder das Grundwasser verunreinigt noch das biologi¬ sche Gleichgewicht des Bodens stört, und welche infolge verbesserter Konstruktion gegenüber der bekannten Ausfüh¬ rung eine effizientere und wirtschaftlichere Behandlung selbst von langen Fahrwegen gewährleistet. Dieses Ziel wird gemäß der Erfindung dadurch erreicht, daß der Träger als nach unten offene Haube mit einem Boden, Seitenwänden und Stirnwänden ausgebildet ist, daß der Düsenbalken am Haubenboden in Fahrtrichtung verstellbar, vorzugsweise in dem in Fahrtrichtung ersten vorderen Drittel der Trägererstreckung, um eine quer zur Fahrtrich¬ tung verlaufende Schwenkachse schwenkbar montiert ist und zumindest zwei zur Fahrtrichtung unterschiedlich geneigte Reihen von Düsen aufweist, und daß die verschwenkbaren seitlichen Trägerteile jeweils ebenfalls als Haube ausge- bildet sind und ihre Schwenkachse am Fahrzeug sowohl höhenverstellbar als auch quer zur Fahrtrichtung verstell¬ bar montiert ist.From US-PS 1 238 861 it is already known to equip a steam locomotive on the underside of its chassis with a height-adjustable support for steam-carrying pipes spanning the track, from which steam can be sprayed against the ballast bed via nozzles. The carrier, which extends in the longitudinal direction of the chassis, is height-adjustable and is provided outside the rails with two articulated side parts which likewise carry steam pipes and which sweep over the side sections of the ballast bed. The known design is structurally complex due to the large number of steam tube pipes, which are distributed over the entire surface of the carrier, and is poor in performance due to the relatively unobstructed steam outlet on all sides. The invention aims to provide a device of the type mentioned in the introduction, which, with efficient destruction by the use of water vapor, offers excellent environmental compatibility, ie neither contaminates the groundwater nor disturbs the biological balance of the soil, and which consequently improved construction compared to the known design ensures a more efficient and economical treatment even of long routes. This goal is achieved according to the invention in that the carrier is designed as a downwardly open hood with a bottom, side walls and end walls, that the nozzle bar on the hood bottom is adjustable in the direction of travel, preferably in the first third of the direction of the beam in the direction of travel, by a transverse the pivot axis extending to the direction of travel is pivotally mounted and has at least two rows of nozzles inclined differently to the direction of travel, and that the pivotable lateral support parts are each also designed as a hood and their pivot axis on the vehicle can be adjusted both in height and transversely to the direction of travel is mounted.
An dieser Stelle sei erwähnt, daß aus der DE-A-36 39 705 ein auf einem Pritschenwagen verfahrbares Dampferzeugungsaggregat zur Unkrautvernichtung bekannt ist, bei dem als Dampfsprühgerät ein im Querschnitt parabel- förmiger Reflektor vorgesehen ist, in dessen Reflektor¬ zentrum ein Sprührohr angeordnet ist. Der Reflektor ist über eine Schlauchleitung mit dem Wagen verbunden, mit Rädern oder Gleitkuven versehen und wird in nicht näher beschriebener Weise über den zu behandelnden Boden bewegt. Über eine Montage und Einstellung des Sprühgerätes am Wagen, insbesondere zur Behandlung von Fahrwegen, wie es die Erfindung vorschlägt, enthält diese Schrift keinerlei Hinweise.At this point it should be mentioned that DE-A-36 39 705 discloses a steam generating unit for weed control which can be moved on a platform truck and in which a reflector with a parabolic cross section is provided as the steam sprayer, in the reflector center of which a spray tube is arranged . The reflector is connected to the car via a hose line, provided with wheels or sliding curves and is moved over the floor to be treated in a manner not described in detail. This document does not contain any information about the assembly and adjustment of the spray device on the car, in particular for the treatment of travel routes, as proposed by the invention.
Gemäß einer in betriebstechnischer Hinsicht speziell für die Behandlung von Weichenzonen von Gleisen bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß der Träger in der Längsmittelebene des Fahrzeuges geteilt ausgebildet ist, wobei jeder Trägerteil auch im Bereich der Längsmittelebene mit einer Seitenwand versehen und für sich höhenverstellbar ist.According to a preferred in operational terms for the treatment of switch zones of tracks Embodiment of the invention provides that the carrier is of divided design in the longitudinal center plane of the vehicle, each carrier part also being provided with a side wall in the region of the longitudinal center plane and being height-adjustable.
Vorzugsweise sind die Seitenwände und Stirnwände des Trägers bzw. jedes Trägerteiles jeweils durch einen Wärmeisolier-Doppelmantel gebildet.The side walls and end walls of the carrier or of each carrier part are preferably each formed by a heat-insulating double jacket.
Nach einem weiteren Merkmal der Erfindung ist das Dampferzeugungsaggregat durch einen von einem Wasser¬ behälter über eine Pumpe beschickten Dampfkessel mit Ausgangsdruckregler gebildet, wobei die Pumpe durch ein Diesel-Stromaggregat elektrisch gespeist und der Dampf¬ kessel durch einen von Gasflaschen gespeisten Gasbrenner beheizt ist.According to a further feature of the invention, the steam generating unit is formed by a steam boiler with an outlet pressure regulator which is fed by a water tank via a pump, the pump being electrically fed by a diesel generator and the steam boiler being heated by a gas burner fed by gas bottles.
Die erfindungsgemäße Konstruktion hat den Vorteil, daß der Dampf aus den Dampfdüsen in einem für die Dampf¬ verteilung bei vorbestimmter Fahrgeschwindigkeit optimalen Bereich der Längserstreckung des Fahrzeuges bzw. des Trägers für den Düsenbalken abgegeben wird, wobei die optimale Dampfverteilung durch Einstellen des Düsenbalkens leicht geregelt werden kann. Die nur gegen den Boden offene Haube stellt sicher, daß der Dampf nicht vorzeitig entweicht, sondern über die gesamte Haubenerstreckung wirksam verteilt wird. Die Wirkung der Dampfaufblasung auf die Pflanzen wird noch durch die spezielle Orientierung der beiden Düsenreihen verstärkt. Durch den Wärmeisolier- Doppelmantel der Seitenwände und der Stirnwände des Trägers wird die Aufrechterhaltung einer wirksamen Dampftemperatur innerhalb der Haube gewährleistet.The construction according to the invention has the advantage that the steam is emitted from the steam nozzles in an area of the longitudinal extension of the vehicle or the support for the nozzle bar which is optimal for the steam distribution at a predetermined driving speed, the optimum steam distribution being easily regulated by adjusting the nozzle bar can. The hood, which is only open towards the floor, ensures that the steam does not escape prematurely, but is effectively distributed over the entire hood extension. The effect of steam inflation on the plants is enhanced by the special orientation of the two rows of nozzles. The thermal insulation double jacket of the side walls and the end walls of the carrier ensures that an effective steam temperature is maintained within the hood.
Weitere Merkmale und Vorteile der Erfindung werden nachfolgend an einem Ausführungsbeispiel unter Bezugnahme auf die Zeichnungen näher erläutert, in denen zeigen:Further features and advantages of the invention are explained in more detail below using an exemplary embodiment with reference to the drawings, in which:
Fig. 1 einen schematischen Längsschnitt durch eine erfindungsgemäße Vorrichtung,1 shows a schematic longitudinal section through a device according to the invention,
Fig. 2 einen schematischen Querschnitt der Vorrichtung nach Fig. 1, undFig. 2 is a schematic cross section of the device of FIG. 1, and
Fig. 3 ein Detail der Vorrichtung nach der Linie III-III in Fig. 2.Fig. 3 shows a detail of the device according to the Line III-III in Fig. 2.
Gemäß Fig. 1 ist auf einem Schienenfahrzeug 1 ein Dampferzeugungsaggregat 2 montiert, welches über flexible Leitungen 3 Dampfdüsen 4', 4" speist. Die Dampfdüsen 4', 4" sind in quer zur Fahrtrichtung in gegenseitiger Verlänge¬ rung angeordneten Düsenbalkenabschnitten 5' gehalten, die je zumindest zwei Reihen von Düsen aufweisen. Wie Fig. 3 zeigt, sind die Düsen 4' der in Fahrtrichtung vorderen Reihe bei Horizontalstellung des* Düsenbalkens vertikal orientiert, wogegen die Düsen 4" der hinteren Reihe schräg orientiert sind, damit die Pflanzen auch in ihrem unteren Bereich von den Dampfdüsen beaufschlagt werden. Die Düsenbalkenabschnitte 5' sind je mittels eines hydraulisch, elektrisch oder mechanisch höhenverstellbaren Trägerteiles 6 an der Unterseite des Rahmens des Schienenfahrzeuges 1 montiert. Wie insbesondere aus Fig. 3 hervorgeht, ist jeder Düsenbalkenabschnitt 5' am zugeordneten Trägerteil 6 mittels einer quer zur Fahrtrichtung verlaufenden, in Fahrtrichtung z.B. in nicht gezeigten Führungen (Pfeil f) verstellbaren Achse A verschwenkbar im ersten vorderen Drittel der Trägererstreckung montiert (vgl. Fig. 1).1, a steam generating unit 2 is mounted on a rail vehicle 1 and feeds steam nozzles 4 ', 4 "via flexible lines. The steam nozzles 4', 4" are held in nozzle bar sections 5 'arranged transversely to the direction of travel in mutual extension. which each have at least two rows of nozzles. As shown in FIG. 3, the nozzles 4 'of the front row in the direction of travel are oriented vertically when the * nozzle bar is horizontal, whereas the nozzles 4 "of the rear row are oriented obliquely, so that the plants are also acted upon by the steam nozzles in their lower region. The nozzle bar sections 5 'are each mounted on the underside of the frame of the rail vehicle 1 by means of a hydraulically, electrically or mechanically height-adjustable support part 6. As can be seen in particular from Fig. 3, each nozzle bar section 5' is attached to the associated support part 6 by means of a cross-directionally in the direction of travel, for example in guides (not shown) (arrow f) adjustable axis A pivotally mounted in the first front third of the beam extension (see. Fig. 1).
Wie aus Fig. 2 hervorgeht, ist der. Träger bei dem gezeigten Ausführungsbeispiel bezüglich der Längsmittel¬ ebene M des Fahrzeuges geteilt ausgebildet, wobei jeder Trägerteil 6 mit einem Boden 61, Seitenwänden 6" sowie Stirnwänden 6"' ausgestattet ist, so daß jeder Trägerteil 6 die Form einer gegen den Untergrund offenen Haube hat. Die Zweiteilung des Trägers ermöglicht es, jeden der beiden Trägerteile 6 für sich höhenzuverstellen bzw. mit Dampf zu beaufschlagen, was sich z.B. für die Behandlung von Weichenbereichen des Gleises in wirtschaftlicher Hinsicht als besonders vorteilhaft erweist. Die Seitenwände 6" und Stirnwände 6"' sind zur Wärmeisolierung als Doppelmäntel mit dazwischen angeordnetem Isoliermaterial ausgebildet. Es versteht sich, daß der Träger und der Düsenbalken auch einteilig ausgebildet sein können.As is apparent from Fig. 2, the. Carrier in the embodiment shown with respect to the longitudinal center plane M of the vehicle is divided, each carrier part 6 being equipped with a bottom 6 1 , side walls 6 "and end walls 6"', so that each carrier part 6 is in the form of a hood which is open to the ground Has. The division of the carrier into two enables each of the two carrier parts 6 to be adjusted in height or to be subjected to steam, which proves to be particularly advantageous in economic terms, for example for the treatment of switch regions of the track. The side walls 6 "and end walls 6"'are designed for thermal insulation as double jackets with insulating material arranged between them. It is understood that the carrier and the nozzle bar can also be formed in one piece.
Wie aus Fig. 2 ferner hervorgeht, sind am Fahrgestell auch zwei seitliche Trägerteile 7 montiert, welche analog den mittleren Trägerteilen 6 ausgebildet und an einer in Längsrichtung des Fahrzeuges verlaufenden Achse B ver¬ schwenkbar montiert sind. Die Achse B ist mittels einer weiteren Achse C unter Zwischenschaltung von Stellzylindern 8 sowohl höhenverstellbar als auch quer zur Fahrtrichtung verstellbar am Fahrzeug 1 montiert. Die Düsenbalkenab- schnitte 5" der seitlichen Trägerteile 7 sind in Verlänge¬ rung der Düsenbalkenabschnitte 5 angeordnet und über flexible Dampfleitungen 3' gespeist. Mit den seitlichen Trägerteilen 7 werden die außerhalb der Schienen liegenden Seitenteile des Schotterbettes überstrichen. Die äußeren Seitenwände der Seitenteile 7 können länger ausgebildet sein als die inneren Seitenwände. Es versteht sich, daß die zu den einzelnen Düsenbalkenabschnitten 5', 5" der Träger- teile 6, 7 verlaufenden flexiblen Dampfleitungen 3, 3' mit nicht gezeigten Ventilen bzw. Regeleinrichtungen für den Dampfdurchsatz versehen sind, so daß sie getrennt schaltbar bzw. regelbar sind.As can also be seen from FIG. 2, two lateral support parts 7 are also mounted on the chassis, which are analogous the middle support parts 6 are formed and are pivotably mounted on an axis B running in the longitudinal direction of the vehicle. The axis B is mounted on the vehicle 1 by means of a further axis C with the interposition of actuating cylinders 8 both adjustable in height and adjustable transversely to the direction of travel. The nozzle beam sections 5 ″ of the lateral support parts 7 are arranged in the extension of the nozzle beam sections 5 and are fed via flexible steam lines 3 ′ longer than the inner side walls. It goes without saying that the flexible steam lines 3, 3 'running to the individual nozzle bar sections 5', 5 "of the carrier parts 6, 7 are provided with valves or regulating devices (not shown) for the steam throughput, so that they can be switched or regulated separately.
Das Dampferzeugungsaggregat 2 ist durch einen Dampf- kessel 9 gebildet, der über eine Pumpe 10 von einem Wasserbehälter 11 beschickt wird. Die Pumpe 10 wird dabei von einem Diesel-Stromaggregat 12 elektrisch gespeist und der Dampfkessel 9 ist durch einen Gasbrenner 13 beheizt, welcher von Gasflaschen 14 gespeist wird. Es versteht sich, daß im Rahmen des Erfindungsgedan¬ kens mannigfaltige Abänderungen der dargestellten Ausfüh¬ rungsform möglich sind; so kann insbesondere die Art und Ausbildung der Dampfdüsen sowie deren Anzahl bzw. die Anzahl der Reihen von Dampfdüsen am Düsenbalken und auch die Orientierung der Dampf--üsen relativ zur Fahrtrichtung gegenüber der dargestellt verändert werden. Wesentlich ist aber, daß zumindest eir. Reihe von vertikalen Düsen und eine Reihe von schräg verlaufenden Düsen vorhanden ist. Es kann auch mehr als ein Düsenbalken vorhanden sein. Ebenso ist der Aufbau des Dampferzeugungsaggregates nur beispiels¬ weise angegeben; jedes bekannte Dampferzeugungsaggregat kann verwendet werden.The steam generating unit 2 is formed by a steam boiler 9, which is fed by a water tank 11 via a pump 10. The pump 10 is electrically fed by a diesel generator 12 and the steam boiler 9 is heated by a gas burner 13 which is fed by gas bottles 14. It goes without saying that, within the scope of the inventive concept, various modifications of the illustrated embodiment are possible; in particular, the type and design of the steam nozzles and their number or the number of rows of steam nozzles on the nozzle bar and also the orientation of the steam nozzles relative to the direction of travel can be changed compared to the one shown. But it is essential that at least eir. There are a number of vertical nozzles and a number of oblique nozzles. There may also be more than one nozzle bar. Likewise, the structure of the steam generating unit is only given as an example; any known steam generator can be used.
Im praktischen Betrieb der Vorrichtung hat sich gezeigt, daß die Fahrtgeschwindigkeit so gewählt werden soll, daß eine Einwirkung des Dampfes auf die Pflanzen während zumindest 2 s erfolgen muß, damit die Pflanzen auf eine Temperatur von zumindest 70° gebracht werden, um die Umwandlung des pflanzlichen Eiweißes sicherzustellen. Im allgemeinen wird angestrebt, unterhalb der Hauben eine Lufttemperatur von 95 bis 100°C zu erzeugen. Die Position des Düsenbalkens 5 kann in Fahrtrichtung vorzugsweise innerhalb des ersten vorderen Drittels des Trägers 6 mittels eines nicht gezeigten Verstellmechanismus, z.B. auf Schienen, optimal eingestellt werden. In practical operation of the device shown that the speed of travel should be chosen so that the plants must be exposed to the steam for at least 2 s so that the plants are brought to a temperature of at least 70 ° in order to ensure the conversion of the vegetable protein. In general, the aim is to generate an air temperature of 95 to 100 ° C below the hoods. The position of the nozzle bar 5 can be optimally adjusted in the direction of travel, preferably within the first front third of the carrier 6, by means of an adjustment mechanism, not shown, for example on rails.
