Den foreliggende opfindelse angår et aggregat for montering på et køretøj for klipning af bevoksning omkring et fra et underlag opstående emne, fortrinsvis omkring skiltepæle, lygtepæle eller kantpæle og autoværn etc. anbragt langs en vejside, og omfattende en bærearm med en bæreramme i den ene ende, på hvilken ved en drejeforbindelse 5 med en i hovedsagen vertikalt orienteret akse, er lejret en i hovedsagen horisontalt orienteret U-formet konsol, hvis respektive ben hver omfatter i det. mindste et, roterende klippehoved, der drives af i det mindste en roterende drivenhed, hvor udsvingene af den U-formede konsol udføres ved en aktuator, hvor enheden med klippehove-deme er styret, f.eks. af en fotocelle som er koblet til en computer, hvilken styring ved 10 hjælp af en motor styrer klippehovedet til at foretage en passende bevægelse under passage af det opretstående emne.BACKGROUND OF THE INVENTION The present invention relates to an assembly for mounting on a vehicle for cutting vegetation around a workpiece-raised workpiece, preferably around signposts, headlamps or edge posts and guardrails etc. arranged along a road side, and comprising a support arm with a support frame at one end. , on which is mounted by a pivotal connection 5 having a generally vertically oriented axis, a generally horizontally oriented U-shaped bracket, the respective legs of which each comprise in it. at least one rotary cutting head driven by at least one rotary drive unit wherein the oscillations of the U-shaped bracket are performed by an actuator where the unit with the cutting head demo is controlled, e.g. of a photocell coupled to a computer, which control by means of a motor controls the cutting head to make an appropriate movement while passing the upright subject.

Fra WO 03/007691 Al kendes et aggregat for montering på et køretøj for klipning af bevoksning omkring et fra et underlag opretstående emne anbragt langs en vejside, 15 som omfatter en bærearm med en bæreramme i den ene ende, på hvilken ved en dreje-forbindelse ved en i hovedsagen lodret orienteret akse er monteret en U-formet enhed, hvis respektive ben hver omfatter i det mindste et roterende klippehoved, der drives af i det mindste en roterende driveenhed. Dette skrift viser i øvrigt, at enheden med klip-pehovedeme kan være styret af en fotocelle, som er koblet til en computer, der ved 20 hjælp af en motor styrer klippehovedet til at foretage en passende bevægelse under passage af det opstående emne.From WO 03/007691 A1 an assembly for mounting on a vehicle for cutting vegetation is known around a workpiece raised along a road side, which comprises a support arm with a support frame at one end, at which at a pivot connection at a generally vertically oriented axis is mounted a U-shaped unit, the respective legs of each comprising at least one rotary cutting head driven by at least one rotary drive unit. Moreover, this document shows that the unit with the cutting heads can be controlled by a photocell connected to a computer which, by means of a motor, controls the cutting head to make an appropriate movement during the passage of the raised object.

Fra fransk patentansøgning nr. 2 413 029 leendes et trærydningsaggregat med en skæ-reindretning, der kan hæves og sænkes ved hjælp af en hydraulisk cylinder. Slcæreind-25 retningen er anbragt på den ene side på en arm, der kan drejes om en horisontal akse ved hjælp af drejeorganer. En bom er forbundet til skovkøretøjet, hvorpå skæreindret-ningen er monteret.From French Patent Application No. 2,413,029, a wood clearing unit is provided with a cutting device which can be raised and lowered by means of a hydraulic cylinder. The locking device is disposed on one side of an arm which can be rotated about a horizontal axis by means of swivels. A boom is connected to the forest vehicle on which the cutting device is mounted.

Et sådan aggregat kendes fra DE-A-4233020, der angår et klippeaggregat for græsbe-30 voksninger omkring i det væsentlige lodret opretstående stolper. Aggregatet udgøres af en U-formet bjælke, der er drejelig om en lodret akse, og som omfatter et antal klippehoveder, der er tilsluttet en drivenhed via en fælles drivrem. Aggregatet er beregnet for montage på et arbejdskøretøj, og drivenheden for klippehovedeme er tilslut- 2 DK 176811 B1 tet og drevet af køretøjets hydrauliksystem. Klippehovederne kan tillige være således lejret på bjælken, at disse er parvis relativt forskydelige i forhold til hinanden. Patent-skriftet angiver imidlertid ikke noget om hvorledes klippeudstyret er lejret til et ar-bejdskøretøj, eller om dette håndteres/styres manuelt, og ej heller hvorledes dette sty-5 res i forhold til de pæle, omkring hvilke klippeaggregatet skal klippe bevoksningen.Such an assembly is known from DE-A-4233020, which relates to a mower deck for grass coverings of substantially vertical upright posts. The assembly is constituted by a U-shaped beam rotatable about a vertical axis and comprising a plurality of cutting heads connected to a drive unit via a common drive belt. The unit is intended for mounting on a working vehicle and the cutting unit drive unit is connected and driven by the vehicle's hydraulic system. The cutting heads may also be so mounted on the beam that these are in pairs relatively displaceable relative to each other. However, the patent does not specify how the cutting equipment is stored for a working vehicle or whether it is handled / controlled manually, nor how it is controlled in relation to the piles around which the cutting unit is to cut the stand.

Nævnte kendte aggregat har imidlertid opfinder bekendt aldrig fundet udbredelse, eftersom den almindelig anvendte fremgangsmåde i forbindelse med vedligeholdelse af græsrabatternes vejside er, at græsset imellem de opstående kantpæle klippes med en 10 på en traktor løst monteret klipper med, en på en traktorlift monteret græsklipper, der er udragende fra siden af traktoren, således at traktoren kører på vejbanen samtidig med, at klipperen opererer på rabatarealet. Klipningen af græsrabatten omkring kant-pælene foretages efterfølgende manuelt ved hjælp af manuelt førte buskrydder. Den normale kapacitet for et arbejdssjak bestående af en maskinfører, der kører traktoren 15 med klipperen, samt to personer med buskrydder samt et transportkøretøj af cirka 4-6 kilometer pr, time. Arbejdet med vedligeholdelse af græsrabatter, herunder klipning af bevoksning langs med kantafgrænsningspælene, er således arbejdskraftintensivt og ressourcekrævende, desuden forekommer der yderligere sikkerhedsmæssige risici ved arbejdet der udføres langs med trafikerede vejarealer, eftersom de vejstrækninger på 20 hvilke der arbejdes ikke kan afspærres uden store gener for afviklingen af trafikken på disse. Dette medfører som oftest, at der skal tegnes en særlig forsikring for de personer der udfører arbejdet.However, the prior art inventor of the prior art has never found propagation, since the commonly used method of maintaining the roadside of the grass rebates is that the grass between the raised edge posts is mown with a mower loosely mounted on a tractor, a mower mounted on a tractor lift, there are projections from the side of the tractor so that the tractor drives on the roadway while the mower operates on the discount area. The mowing of the grass discount around the edge posts is then done manually using manually operated bush spices. The normal capacity for a working chess consisting of a machine driver driving the tractor 15 with the mower, as well as two persons with bus spices and a transport vehicle of approximately 4-6 kilometers per hour. Thus, the work of maintaining grass discounts, including mowing of vegetation along the boundary posts, is labor-intensive and resource-intensive, and there are additional safety risks to the work carried out along busy road areas, as the sections of road 20 which are worked cannot be blocked without major nuisance. the settlement of traffic on these. This usually means that a special insurance must be taken out for the persons performing the work.

Det er formålet med opfindelsen at angive et aggregat af den indledningsvis angivne 25 type, der muliggør en væsentlig reduktion af ressource-/arbejdskraftforbruget i forbindelse med vedligeholdelse af græsrabatter langs med veje samt med klipning af bevoksningen omkring de langs med nævnte veje forekomne kantafgrænsningspæle.SUMMARY OF THE INVENTION It is an object of the invention to provide an aggregate of the type initially provided, which enables a significant reduction of resource / labor consumption in connection with maintenance of grass discounts along roads and with cutting of the vegetation around the edge boundary piles found along said roads.

Et sådant aggregat er kendetegnet ved, at bærerammen yderligere omfatter i det mind-30 ste et roterende klippehoved, fortrinsvis placeret i bærearmens længdeakse, der drives af en roterende drivenhed, og hvor den U-formede konsol er forbundet med i det mindste en første sensorenhed stående i forbindelse med en styreenhed, hvilken styreenhed er således indrettet, at detektering ved hjælp af den første sensorenhed af en 3 DK 176811 B1 opstående genstand imellem benene af den U-formede konsol, under fremføring af denne i køretøjets kørselsretning, vil medføre en aktivering af en drivenhed på en ro-terbar lejring af bærerammen i enden af bæfearmeii, og dermed svingning af den U-formede konsol omkring nævnte bærearmens længdealese, at bærearmen (10) er sving-5 bart lejret omkring en i hovedsagen horisontalt orienteret akse (52) til en bæreenhed (54), ved drejeenhed (58) drevet af en drivenhed (56), og at bærerenheden udgøres af en ved mekaniske og/eller hydrauliske midler (59), tværforskydelig bom, i hvis forskydelige ende (62) bærearmen (10) er monteret, og hvilken forskydelig bom (60), der ved en drejeforbindelse er lejret svingbart omkring en horisontalt orienteret akse, nær 10 standart koblingsmidler for montering på et arbejdskøretøj.Such an assembly is characterized in that the support frame further comprises at least one rotary cutting head, preferably located in the longitudinal axis of the support arm driven by a rotary drive unit, and wherein the U-shaped bracket is connected to at least a first sensor unit. standing in conjunction with a control unit, which control unit is arranged so that detection by means of the first sensor unit of an object raised between the legs of the U-shaped bracket, while driving it in the direction of travel of the vehicle, will cause an activation of a drive unit on a rotatable bearing of the support frame at the end of the beaker arm, and thus pivoting the U-shaped bracket about the longitudinal reading of said support arm, that the support arm (10) is pivotably mounted around a generally horizontally oriented axis (52). ) to a carrier unit (54), at a rotary unit (58) driven by a drive unit (56), and that the carrier unit is constituted by a mechanical and / or hydraulic unit means (59), a slidable boom, in which the slidable end (62) of the support arm (10) is mounted, and said slidable boom (60), which is pivotally mounted about a horizontally oriented axis, near 10 standard coupling means for mounting on a working vehicle.

Fordelene ved et sådan system er flere. Aggregatet er monterbart på et arbejdskøretøj, der i det efterfølgende benævnes en traktor, uden at dette på nogen måde skal virke begrænsende for opfindelsen. Indretningen af aggregatet ifølge opfindelsen indebærer, 15 at det. vil være muligt at foretage styring af klipningen omkring kantpælene placeret i rabatten under en kontinuerlig fremføring af aggregatet monteret på en traktor. Dette vil simpelthen ske ved, at den U~formede konsol under passagen af kantpælen vil blive aktiveret i drejende retning, således at de roterende klippehoveder vil blive bragt rundt omkring periferien af kantpælen. Den drejende bevægelse initieres ved, at den første 20 sensorenhed detekterer en kantpæl imellem benene på den U-formede konsol, hvorefter styreenheden aktiverer aktuatoren for drejning af den U-formede konsol under konsollens passage af kantpælen. Det vil således være muligt at foretage klipningen af bevoksningen omkring kantpælen uden nogen aktiv medvirken fra føreren af traktoren, udover at denne skal tilsikre en rimelig nøjagtig styring af traktoren under klippe-25 arbejdet. Klipningen kan således finde sted samtidigt med at traktoren er i fremdrift, dvs. opstandsning for gennemførelse af klippearbejdet omkring kantafgrænsningspælene overflødiggøres.The benefits of such a system are several. The assembly is mountable on a working vehicle, hereinafter referred to as a tractor, without this in any way limiting the invention. The arrangement of the assembly according to the invention implies that it. it will be possible to control the mowing around the edge posts placed in the rebate during a continuous feed of the unit mounted on a tractor. This will simply be done by activating the U-shaped bracket during the passage of the edge pile in a rotating direction so that the rotary cutting heads will be brought around the periphery of the edge pile. The rotary motion is initiated by the first sensor unit detecting an edge pile between the legs of the U-shaped bracket, after which the controller activates the actuator for rotating the U-shaped bracket during the bracket passing the edge pole. Thus, it will be possible to mow the vegetation around the edge pile without any active involvement of the operator of the tractor, except that it must ensure a reasonably accurate control of the tractor during the mowing operation. The trimming can thus take place at the same time as the tractor is in progress, ie. resurrection to complete the cutting work around the edge boundary poles is unnecessary.

Ved at et yderligere klippehoved er placeret på bærerammen i forlængelse af bærear-30 mens længdeakse, sikres det at dette klippehoved altid vil klippe bevoksningen imellem kantafgrænsningen og den imod denne vendende side af en kantpæl.By placing an additional cutting head on the support frame in extension of the longitudinal axis of the support arm, it is ensured that this cutting head will always cut the growth between the edge boundary and the opposite side of an edge pole.

4 DK 176811 B1 I den hensigt at sikre aggregatet tmod beskadigelser udover samtidig med at sikre mod en vis ensartet klippehøjde for bevoksningen omkring pælene, kan enden af bærearmen i hvilken bærerammen er monteret, ved mekaniske og/eller hydrauliske midler, der aktiveres via styreenheden være aksialt forskydelige i bærearmens længdealtse.4 DK 176811 B1 In order to secure the unit against damage in addition to ensuring a certain uniform cutting height for the vegetation around the posts, the end of the support arm in which the support frame is mounted can be by mechanical and / or hydraulic means activated via the control unit. axially displaceable in the longitudinal axis of the support arm.

5 Herved opnås det, at det vil være muligt at beskytte aggregatet imod stød og slag fra eventuelt forekommende sten m.m., som kan forefindes i det areal, hvor bevoksningen klippes. Desuden vil det være muligt at kompensere for højdevariationer omkring pælene.Hereby it is achieved that it will be possible to protect the aggregate from bumps and strokes from any occurring stones, etc., which can be found in the area where the vegetation is cut. In addition, it will be possible to compensate for height variations around the posts.

10 1 den hensigt yderligere at fritage føreren af traktoren for at skulle foretage justering af aggregatets højde over rabatten, kan bærearmen omfatte en anden sensorenhed, for detektering af den aktuelle afstand imellem underlaget og de roterende klippehoveder, hvilken anden sensorenhed står i forbindelse med slyreenheden der kan være således indrettet at, i tilfælde af, at der ved den anden sensorenhed detekteres en afstand, der 15 ligger udenfor en intervalgrænse omkring en på forhånd i slyreenheden indlagt værdi, aktiverer styreenheden de mekaniske og/eller de hydrauliske midler for gennemførelse af en aksi al forskydning af bærearmen til den ønskede værdi, svarende til en foretrukket klippehøjde. Herved opnås der et fuldautomatisk system, som sikrer en ensartet klippehøjde, men som også beskytter aggregatet imod utilsigtet stød imod uautorisere-20 de genstande, der måtte være beliggende i det areal, hvori aggregatet benyttes til klipning af bevoksning.In order to further exempt the driver of the tractor from having to adjust the height of the unit above the rebate, the support arm may comprise another sensor unit for detecting the actual distance between the base and the rotary cutting heads, which other sensor unit communicates with the slider unit which may be arranged so that, in case the second sensor unit detects a distance which is outside an interval boundary around a value entered in advance in the slide unit, the control unit activates the mechanical and / or hydraulic means for carrying out an axle. all displacement of the support arm to the desired value corresponding to a preferred cutting height. Hereby a fully automatic system is obtained which ensures a uniform cutting height, but which also protects the unit against unintentional shocks against unauthorized objects which may be located in the area in which the unit is used for cutting vegetation.

Eftersom den U formede bjælke drejemekanisme ikke tillader en 360° drejning, og at særlige arbejdssituationer under tiden kan fordre en vinkeldrejning af den U-formede 25 bjælke, der ligger udenfor det normale drejningsinterval for den U-formede bjælke, som er beliggende imellem 0° og 180°, fortrinsvis i intervallet 0°-130°, kan svingningen af den U-formede konsol omkring den vertikale akse ved drejeforbindelsen udføres ved en akt ua tor, der styres via aggregatets styreenhed.Since the U-shaped beam turning mechanism does not allow for a 360 ° rotation, and special working situations may in the meantime require an angular rotation of the U-shaped beam which is outside the normal rotation interval of the U-shaped beam, which is located between 0 ° and 180 °, preferably in the range of 0 ° -130 °, the oscillation of the U-shaped bracket about the vertical axis of the pivot joint can be performed by an actuator controlled via the control unit of the assembly.

30 Herved opnås den fordel, at der kan kompenseres for vinkeldrejninger i forhold til fremdriftsretningen (traktorens kørselsretning) af aggregatet, således at aggregatets stilling kan tilpasses relevante særlige arbejdssituationer.30 The advantage of this is that it is possible to compensate for angular rotations in relation to the direction of travel (tractor direction of travel) of the unit, so that the position of the unit can be adapted to relevant special working situations.

Aggregatet ifølge opfindelsen kan være forbundet til traktoren på forskellig vis og ved forskellige bæreenheder, fælles for disse er dog, at bæreenheden skal kunne være i stand til åt gennemføre en siderettet forskydning af aggregatet under fremføringen af dette i arbejdssituationen, i den sammenhæng kan det foretrækkes, at bæreenheden 5 udgøres af en ved mekaniske og/eller hydrauliske midler, tværforskydelig bom, i hvis forskydelige ende bærearmen er monteret, og hvilken forskydelig bom omfatter standardkoblingsmidler for montering på et arbejdskøretøj, fortrinsvis en traktor.The assembly according to the invention may be connected to the tractor in different ways and at different support units, however, common to these is that the support unit must be able to carry out a lateral displacement of the assembly during advancing it in the working situation, in which context it may be preferred. the support unit 5 is constituted by a transverse slidable boom by mechanical and / or hydraulic means, the sliding end of which the supporting arm is mounted, and which slidable boom comprises standard coupling means for mounting on a working vehicle, preferably a tractor.

Det vil herved være muligt for føreren af traktoren at foretage en manuelt styret side-10 forskydning af aggregatet, således af dette føres i den korrekte afstand fra vejsiden hen imod opstående emner, som for eksempel skiltepæle og kantafgrænsningspæle etc., uanset om disse er meget høje, idet der ikke er tale om maskinkomponenter ovenover selve klippeområdet.In this way, it will be possible for the operator of the tractor to make a manually controlled side-displacement of the unit, thus guiding it at the correct distance from the road side towards upstanding objects, such as signposts and edge boundary piles, etc., whether very high, since there are no machine components above the cutting area itself.

15 I den hensigt at sikre maskinføreren gode oversigtsforhold i forbindelse med anvendelse af aggregatet, vil det være hensigtsmæssigt at standardkoblingsmidlet imellem bæreenheden og traktoren udgøres af en med en A-ramme på en traktors forende samvirkende ramme. Herved vil aggregatet være placeret i operatørens synsfelt, og denne vil således være i stand til at foretage kompenserende operationer med aggregatet.In order to ensure good overview of the machine operator when using the unit, it will be appropriate that the standard coupling means between the support unit and the tractor be constituted by one with an A-frame on the front of the tractor's cooperating frame. In this way, the unit will be located in the operator's field of view and thus it will be able to perform compensatory operations with the unit.

20 I visse tilfælde kan det være hensigtsmæssigt at flytte aggregatet fra den ene side, eksempelvis den højre side, til el operationsområde beliggende på venstre side af traktorens kørselsretning. Dette vil umiddelbart ikke være muligt, uden at der gennemføres væsentlige ombygningsarbejder af aggregatet. Imidlertid er det ved opfindelsen indset, 25 at en særlig udførelsesform af aggregatet, kan den tværforskydelige bom ved en dreje forbindelse være lejret svingbart omkring en horisontalt, og i kørselsretningen orienteret akse nær koblingsmidlerne for tilkoblingen af aggregatet til arbejdskøretøj et. Herved opnås det, at aggregatet kan svinges fra en arbejdsposition på højre side af traktoren, til en arbejdsposition på venstre side af traktoren i forhold til dennes kørselsret-30 ning. Kombineres denne egenskab med det forhold, at bærearmen kan være svingbart lejret omkring en i hovedsagen horisontalt orienteret akse til bæreenheden eller i enden af den tværforskydelige bom, opnås således mulighed for en let og hurtig omskiftning af aggregatets placering fra traktorens højre side til traktorens venstre side, f 6 DK 176811 B120 In some cases, it may be convenient to move the unit from one side, for example the right side, to the operating area located on the left side of the tractor's direction of travel. This will not immediately be possible without significant refurbishment work being carried out by the unit. However, it is recognized by the invention that in a particular embodiment of the assembly, the transverse slidable boom can be mounted pivotally about a horizontal, and in the direction of travel, oriented axis near the coupling means for connecting the assembly to the working vehicle. Hereby it is achieved that the unit can be pivoted from a working position on the right side of the tractor, to a working position on the left side of the tractor in relation to its direction of travel. If this feature is combined with the fact that the support arm can be pivotally mounted about a generally horizontally oriented axis to the support unit or at the end of the transverse boom, it is possible to easily and quickly change the position of the unit from the right side of the tractor to the left side of the tractor. , f 6 DK 176811 B1

Omskiftningen kan endvidere lettes yderligere ved, at den tværforskydelige bom kan omfatte en vertikalt orienteret tandkrans, hvis tsender står' i forbindelse med et tandhjul på en på ståndardkoblingsmidleme monteret og en drivenhed roterbar drevet drivaksel Herved vil operatøren af aggregatet kunne foretage nævnte omskiftning af aggregatets 5 placering fra højre til venstre side fra førerhuset, uden at skulle foretage manuelle operationer i øvrigt.Furthermore, the switching can be further facilitated by the fact that the transverse slidable boom can comprise a vertically oriented gear ring whose transmitter is in contact with a gear wheel mounted on a standard coupling means and a drive unit rotatable driven shaft Hereby the operator of the unit can make said switch positioning from right to left side of the cab, without having to perform manual operations otherwise.

Det skal anføres, at bæreenheden alternativt endvidere kan udgøres af en leddelt og svingbar arm i lighed med en kranarm/gravearm på en hydratdisk gravemaski-10 ne/rendegraver, hvis bevægelser udføres ved mekaniske og/eller hydrauliske midler.It should be noted that the support unit may alternatively also be constituted by an articulated and pivotal arm similar to a crane arm / excavator arm of a hydrate disk excavator / backhoe whose movements are performed by mechanical and / or hydraulic means.

Herved vil operationsmulighedeme med aggregatet ifølge opfindelsen blive betydeligt udvidet, Der vil således kunne foretages klipning omkring kantpæle placeret på skråninger m.m. om nødvendigt. Det vil dog i den henseende være nødvendigt at udvikle en betydeligt mere kompleks styring af aggregatet via styreenheden.Hereby, the possibilities of operation with the assembly according to the invention will be considerably expanded, thus cutting can be made around edge posts placed on slopes etc. if necessary. However, in this regard it will be necessary to develop a significantly more complex control of the unit via the control unit.

15 I den hensigt yderligere at automatisere aggregatets drift og således fritage operatøren for at skulle koncentrere sig om andet end at føre traktoren parallelt med kantafgrænsningen af vejen, kan bæreannen yderligere omfattet en tredje sensorenhed, for detektering af en kantafgrænsning af underlaget, hvilken sensorenhed via aggregatets styreen-20 hed er forbundet med de mekaniske og/eller hydrauliske midler på den tværforskydeli-ge bom, eller den leddelte svingbare arm for kompensering af den siderettede placering af den U-fomiede ramme med klæbehovedeme i forhold til kantafgrænsningen.In order to further automate the operation of the unit and thus exempt the operator from having to concentrate on anything other than driving the tractor parallel to the edge boundary of the road, the support arm may further comprise a third sensor unit for detecting an edge boundary of the substrate which sensor unit via the unit control unit is connected to the mechanical and / or hydraulic means of the transverse boom, or the articulated pivotal arm to compensate the lateral placement of the U-shaped frame with the adhesive heads relative to the edge boundary.

Herved bliver det muligt, at aggregatet praktisk taget bliver komplet selvstyrende i det øjeblik, at dette er placeret parallelt med og i græsrabatten langs eksempelvis en vej, 25 hvor der skal foretages klipning af bevoksningen rundt om kantpælene, idet sensorenheden i kombination med styreenheden og de øvrige sensorenheder stort set vil passe sig selv. Det skal endvidere anføre, at sensor enhederne tillige tjener til start og stop af klippehovedeme på aggregatet, således at disse ikke er i drift hele tiden, men kun aktiveres, når disse nærmer sig en kantafgrænsningspæl, omkring hvilken bevoksningen 30 skal klippes.This makes it possible for the unit to become practically completely self-controlled the moment it is placed parallel to and in the grass discount along, for example, a path 25, where cutting of the vegetation must be made around the edge posts, the sensor unit in combination with the control unit and the other sensor units will largely look after themselves. It should also be noted that the sensor units also serve to start and stop the cutting heads on the assembly so that they are not in operation all the time, but are only activated when approaching an edge boundary pole around which the vegetation 30 is to be cut.

Den således praktisk talt fuldkomne automatisering af aggregatet monteret foran på en traktor, der er forsynet med en A-ramme, betyder dette, at der på traktorens lift bagest 7 DK 176811 B1 kan monteres en egentlig slåmaskine for klipning af bevoksningen på den øvrige del af rabatarealet langs med en vej. Operatøren af traktoren kan således under kørslen koncentrere sig otti hævning og sænkning af nævnte klippemaskine, når denne skal passere kant afgrænsnings pælene langs med vejen.The virtually complete automation of the unit mounted on the front of a tractor equipped with an A-frame, means that on the tractor lift at the rear of the tractor can be mounted an actual mower for cutting the vegetation on the other part of the tractor. the discount area along a road. Thus, the operator of the tractor may concentrate during the ride on raising and lowering said mower when it is to pass the edge of the piles along the road.

Ved aggregatet ifølge opfindelsen er der således opnået mulighed for, at én person vil kunne foretage klipning af helt op til 5-6 kilometer græsrabat inklusiv klipning af bevoksningen omkring kantafgrænsningspælene, hvilket kan sammenlignes med den hidtil anvendte metode, hvor der benyttes en traktor med en slåmaskine, samt et ar-10 bejdssjak bestående af to personer med bliskrydder og en bil, der kan foretage klipning af cirka 4-6 kilometer pr. time. Ved aggregatet ifølge opfindelsen er der opnået en væsentlig ressourcebesparelse, nemlig besparelse af en arbejdsvogn samt to personer med buskrydder, til rydning af tilnærmelsesvist samme strækning, der ved udnyttelse af aggregatet ifølge opfindelsen, kan udføres af en person.Thus, the unit according to the invention has the possibility that one person will be able to mow up to 5-6 kilometers of grass discount, including mowing of the vegetation around the edge boundary poles, which can be compared with the hitherto used method where a tractor with a tractor is used. mower, as well as an ar-10 picket chess consisting of two people with blades and a car capable of mowing approximately 4-6 kilometers per head. hour. In the aggregate according to the invention, a substantial saving of resources has been achieved, namely the saving of a working trolley and two persons with bush spices, for clearing approximately the same distance that can be carried out by one person when using the aggregate according to the invention.

Kantafgrænsningspæle langs vejarealer bliver ofte temmelig tilsmudsede, hvilket også gælder de refleksgivende elementer, der normalt er placeret på disse, hvilket betyder, at vejens sideafgrænsninger under kørsel i mørke bliver mere diffuse for trafikanter.Edge boundary poles along road areas are often quite soiled, as are the reflective elements normally placed on them, which means that the side boundaries of the road during dark driving become more diffuse for road users.

Det er derfor almindeligt kendt, at nævnte kantafgrænsningspæle cirka 1 gang årligt 20 vaskes. Dette arbejde er i sig selv temmelig ressourcekrævende og kan enten udføres manuelt, hvilket fordrer medvirken af en arbejdsvogn og en til to mand, alternativt en traktor med selvstændigt opererende aggregat med roterende børster og vandtilførsel, der således kører langs med vejsiden som en selvstændig operation.It is therefore well known that said edge demarcation piles are washed approximately once a year. This work in itself is quite resource intensive and can either be done manually, requiring the assistance of a work trolley and one to two men, alternatively a self-operating tractor with rotating brushes and water supply, thus driving along the road side as an independent operation.

25 Der er imidlertid ved opfindelsen indset, at denne ekstra foranstaltning for vaskning af kantafgrænsningspælene kan være indbefattet i aggregatet, idet bærearmen yderligere kan omfatte en i forhold til bærearmen og i bærearmens længderetning selvstændigt forskydeligt lejret, og ved en åktuator forskydelig konsol omfattende i det mindste to parallelt orienterede, roterbart lejrede aksler, der ved drivenheder bringes til rotation, 30 på hvilke aksler rindes børster samt i det mindste en dyse til udsprøjtning af vand under tryk ril fra et på køretøjet forråd i børsteområdet.However, it is recognized by the invention that this additional means for washing the edge boundary posts may be included in the assembly, the support arm further comprising a independently displaceable bearing relative to the support arm and in the longitudinal direction of the support arm comprising at least one actuator two parallel oriented rotatably mounted shafts brought into rotation by drive units, 30 on which shafts are brushed and at least one nozzle for spraying water under pressure ril from a vehicle stock in the brush area.

Det vil således være muligt at kombinere klipning af bevoksning omkring kantafgrænsningspæle med en samtidig vask og rengøring af disse. Det vil dog her være en forudsætning, at traktoren må gøre et kort ophold under gennemførelse af vaskcproee duren, men alt andet lige vil aggregatet forsynet med nævnte vaskearrangement med-5 føre en besparelse af arbejdsoperationerne ved vedligeholdelsen af kantaf grænsningspæle. Som udgangspunkt forudsættes det, at børstearrangementet betjenes fra førersædet på traktoren, men udførelsesformer omfattende sensorudstyr m.m. i kombination med en styreenhed, der styrer selve børsteoperationen og væsketilførslen under vasken, vil absolut være en mulig udførelsesfonn. Det forudsættes naturligvis, 10 at akslerne, på hvilke børsterne er monteret, har en passende afstand i forhold til hinanden, således at kantafgrænsningspælen kan placeres imellem disse. Umiddelbart vil det også være at foretrække, at de roterbart lejrede aksler er relativt forskydelige i forhold til hinanden i aktuatorer. Herved opnås mulighed for at indføre børsterne omkring kantafgrænsningspælen med større tolerance.Thus, it will be possible to combine cutting of vegetation around edge boundary piles with a simultaneous washing and cleaning thereof. However, it will be a prerequisite here that the tractor has to make a short stay during the execution of the washing process, but all else equal, the unit provided with said washing arrangement will save the working operations in the maintenance of border posts. As a starting point, it is assumed that the brush arrangement is operated from the driver's seat on the tractor, but embodiments comprising sensor equipment and the like. in combination with a control unit which controls the brush operation itself and the liquid supply under the sink, will definitely be a possible embodiment. Of course, it is assumed that the shafts on which the brushes are mounted have a suitable distance relative to each other, so that the edge boundary pole can be placed therebetween. Immediately, it would also be preferable for the rotatably mounted shafts to be relatively slidable relative to each other in actuators. This allows the brushes to be inserted around the edge boundary pile with greater tolerance.

Det forudsættes endvidere, at aggregatet er udført således, at dette kan tilsluttes energiforsyning på den traktor, på hvilken de er monteret, det vil sige, at drivenhedeme for de roterende klippehoveder, de mekaniske og/eller hydrauliske midler, aktuatorer samt siyrenenheden energiforsynes/drives af køretøjets elektriske og/eller hydrauliske sy-20 stem. Aggregatet vil således kunne tilsluttes traktoren på samme måde som et almindeligt arbejdsredskab ved tilslutning på traktorens A-ramme foran på traktoren og ved tilslutning af hydraulik med slangetilkoblinger og det elektriske system ved kobling af styre- og elkabler stående i forbindelse med traktorens elektriske system og diverse betjeningsbokse/-pulte placeret hensigtsmæssigt i traktorens førerhus.Furthermore, it is assumed that the unit is designed so that it can be connected to power supply on the tractor on which they are mounted, that is, the drive units for the rotary cutting heads, the mechanical and / or hydraulic means, actuators as well as the power unit / power unit of the vehicle's electrical and / or hydraulic system. The unit can thus be connected to the tractor in the same way as a normal working tool when connecting to the tractor's A-frame at the front of the tractor and by connecting hydraulics with hose connections and the electrical system by connecting control and power cables in connection with the tractor's electrical system and various control boxes / desks conveniently located in the tractor cab.

25 I særlige tilfælde kan drivenhedeme, eksempelvis drivenhedeme for de roterende klip-pehoveder, være forsynet med selvstændige drivenheder, for eksempel elektriske eller benzindrevne motorer.In special cases, the drive units, for example the drive units for the rotary cutting heads, may be provided with independent drive units, for example electric or gasoline powered motors.

30 Det skal endvidere bemærkes, at aggregatet vil kunne stabilisere traktoren under kørslen, eftersom den slåmaskine, som normalt placeres på bagenden af traktoren på dennes liftenhed, fordrer en kontravægt på traktorens forende. Aggregatets egenvægt vil således yderligere kunne overflødiggøre nævnte nødvendige kontravægt, og det vil 9 DK 176811 B1 være oplagt at forsyne en traktor med aggregatet ifølge opfindelsen placeret forrest, og en traditionel klippeenlied i forbindelse med traktorens liftindretning.30 It should also be noted that the unit will be able to stabilize the tractor while driving, since the mower, which is normally placed on the rear of the tractor on its lift unit, requires a counterweight on the front of the tractor. The unit's own weight will thus be able to further obviate said necessary counterweight, and it will be obvious to provide a tractor with the assembly according to the invention located at the front, and a traditional cutting joint in connection with the tractor's lifting device.

I fig. 1 ses et aggregat 2 for montering på et køretøj (3), jf. fig. 9A, for klipning af bevoksning 4 omkring fra et underlag 5 opstående emner 6, fortrinsvis omkring kantpæle anbragt langs en vejside 8.1 fig. 1,3,4 m.fl, er vejsidens afgrænsning markeret som en 25 tænkt kant ved en linie 8.In FIG. 1 shows an assembly 2 for mounting on a vehicle (3), cf. FIG. 9A, for cutting vegetation 4 around items 6 arising from a substrate 5, preferably around edge posts arranged along a road side 8.1 FIG. 1,3,4 et al., The boundary of the road side is marked as a 25 intended edge at a line 8.

Aggregatet omfatter en bærearm 10 med en bæreramme 12 i den ene ende, på hvilken ved en drejeforbindelse 13 med en i hovedsagen vertikalt orienteret akse 14, er lejret en i hovedsagen horisontalt orienteret U formel konsol 16. Den U-formede konsol har 30 et første og et andet ben 18, 20, der hver omfatter i den viste udførelsesform indbefatter et roterende klippehoved 22, 24, der drives af i det mindste en roterende drivenhed 26, 28, der i den viste udførelsesform udgøres af en hydraulisk drevet motor, beregnet for, på kendt måde at være tilsluttet et hydrauliksystem (ikke vist) på køretøjet 3.The assembly comprises a support arm 10 with a support frame 12 at one end, on which is mounted at a pivotal connection 13 with a substantially vertically oriented axis 14, a substantially horizontally oriented U formal bracket 16. The U-shaped bracket 30 has a first and a second leg 18, 20, each comprising in the illustrated embodiment, includes a rotary cutting head 22, 24 driven by at least one rotary drive unit 26, 28, which in the illustrated embodiment is a hydraulically driven motor, designed for , known in the art to be connected to a hydraulic system (not shown) on the vehicle 3.

Som det fremgår af .fig. 5 med flere er bærerammen 12 lejret til enden af bærearmen 10, ved en roterbar lejring 48 der omfatter en mekanisk drivenhed 50 der aktive-res/styres via aggregatets styreenhed 40.As shown in .fig. 5 and more, the support frame 12 is mounted to the end of the support arm 10, by a rotatable bearing 48 comprising a mechanical drive unit 50 actuated / controlled via the control unit 40 of the assembly.

5 Den U-formede konsol 16 er tillige forbundet med en aktuator 30. der tillige er forbundet med bærerammen 12, således at drejning af den U-formede ramme omkring drejeforbindelsen 13 omkring en vertikalt orienteret akse (14) foranlediges ved aktivering af aktuatoren.The U-shaped bracket 16 is also connected to an actuator 30. which is also connected to the support frame 12, so that rotation of the U-shaped frame around the pivot connection 13 about a vertically oriented axis (14) is caused by actuation of the actuator.

10 Som det endvidere fremgår af fig. 1 med flere omfatter bærerammen 12 yderligere et roterende klippehoved 32, der er placeret i bærearmens længdeakse 34. Klippehovedet 32 drives af en roterende drivenhed 36. Som det navnlig fremgår af fig. 3, omfatter den U-formede konsol 16 en sensorenhed 38, for detektering af genstande imellem benene 18, 20 af den U-formede konsol 16. Sensorenheden 38 er forblindet med en 15 styreenhed 40, jf. fig. 8 og fig. 9A, der bl.a. styrer bevægelserne af den roterbare lejring 48 af bærerammen (12), ved aktivering af den mekaniske drivenhed 50, hvorved den U-formede konsol 16 drejes, Styreenheden aktiverer endvidere drivenhedeme 26, 28, 36. for klippehovederne 22, 24, 32. Styreenheden 40 er således indrettet, at detektering ved hjælp af den første sensorenhed 38 af en opstående genstand 6, der i den 20 viste udførelsesform udgøres af en vejkantafgrænsningspæl, imellem benene 18, 20 af den U-formede konsol 16, under fremføring af denne i køretøjets kørselsretning A, vil medføre en aktivering af drivenheden 50 for svingning af bærerammen 12 omkring bærearmens centerakse 34, og dermed den U-formede konsol 16 omkring nævnte vertikalt orienterede akse 34, samtidigt med at den aktiverer drivenhederne 26, 28, 36, 25 hvorved bevoksningen 4 omkring den opstående genstand 6, samt bevoksningen imellem denne og kantafgrænsningen 8, klippes af henholdsvis klippehovederne 22,24, og af klippehovedet 36. Ved at klippehovedet 36 er placeret på bærerammen 12 i forlængelse af centeraksen 34 af bærearmen 10, sikres det at dette klippehoved altid vil klippe bevoksningen imellem kantafgrænsningen 8 og den imod denne vendende side af 30 den opstående genstand 6.10 Furthermore, as can be seen from FIG. 1, the support frame 12 further comprises a rotary cutting head 32 located in the longitudinal axis of the support arm 34. The cutting head 32 is driven by a rotary drive unit 36. As can be seen in particular from FIG. 3, the U-shaped bracket 16 comprises a sensor unit 38 for detecting objects between the legs 18, 20 of the U-shaped bracket 16. The sensor unit 38 is blinded by a control unit 40, cf. 8 and FIG. 9A, controls the movements of the rotatable bearing 48 of the support frame (12), by activating the mechanical drive unit 50, thereby turning the U-shaped bracket 16, the control unit further activates the drive units 26, 28, 36. for the cutting heads 22, 24, 32. The control unit 40 is arranged so that detection by means of the first sensor unit 38 of an upright object 6, which in the illustrated embodiment is constituted by a roadside boundary pole, between the legs 18, 20 of the U-shaped bracket 16, while driving it in the direction of travel of the vehicle A, will cause activation of the drive unit 50 to pivot the support frame 12 about the center axis 34 of the support arm, and thus the U-shaped bracket 16 around said vertically oriented axis 34, while activating the drive units 26, 28, 36, 25 around the raised object 6, as well as the vegetation therebetween and the edge boundary 8, are cut by the cutting heads 22,24 and by the cutting head 36. By a If the cutting head 36 is positioned on the support frame 12 in extension of the center axis 34 of the support arm 10, it is ensured that this cutting head will always cut the growth between the edge boundary 8 and the object 6 facing the opposite side of 30.

Som det fremgår af fig. 1, 2, 3, 4 og 5 udgøres bærearmen 10 af en hydraulikcylinder, hvis stempel 44 udgør den ende af bærearmen 10 i hvilken bærerammen 12 er monte- DK 176811 B1 π ret. Hydraulikcylinderens stempel 44 er aktiverbar via styreenheden 40, hvorved der opnås en aksial forskydning af bærerammen 12 i enden af stemplet. Forskydningen vil således medføre en vertikal forskydning af bærerammen 12, og denned af den U-formede konsol 16 med Idippehovedeme 22, 24, samt af klippehovedet 36, hvorved 5 der kan foretages en justering af klippehøjden for bevoksningen 4 i forhold til underlagets niveau.As shown in FIG. 1, 2, 3, 4 and 5, the support arm 10 is constituted by a hydraulic cylinder, the piston 44 of which is the end of the support arm 10 in which the support frame 12 is mounted. The piston 44 of the hydraulic cylinder is actuable via the control unit 40, thereby obtaining an axial displacement of the support frame 12 at the end of the piston. Thus, the displacement will result in a vertical displacement of the support frame 12, and that of the U-shaped bracket 16 with the Idler heads 22, 24, and of the cutting head 36, whereby an adjustment of the cutting height of the growth 4 can be made in relation to the level of the substrate.

I en særlig udførelsesform kan bærearmen 10 omfatte en anden sensorenhed (ikke vist), stående i forbindelse med styreenheden 40, for detektering af den aktuelle af-10 stand imellem underlaget 5 og de roterende klippehoveder 22, 24, 32, og hvor styreenheden 40, i tilfælde af at denne afstand afviger fra en på forhånd i styreenheden 40 indlagt værdi, er således indrettet at denne aktiverer hydraulikcylinderens stempel 44 for gennemførelse af en aksial forskydning af den del 42 af bærearmen 10, der omfatter bærerammen 12 til den ønskede værdi, svarende til den foretrukne klippehøjde.In a particular embodiment, the support arm 10 may comprise another sensor unit (not shown), in communication with the controller 40, for detecting the current distance between the support 5 and the rotary cutting heads 22, 24, 32, and wherein the controller 40, in the event that this distance deviates from a value entered in advance in the control unit 40, it is arranged to activate the piston 44 of the hydraulic cylinder for carrying out an axial displacement of the part 42 of the support arm 10 comprising the support frame 12 to the desired value corresponding to to the preferred cutting height.

15 Herved vil det være muligt at aggregatet sammen med styreenheden foretager kompenserende justeringer af klippehøjden i forhold til variationer af terrænhøjden i klippeområdet-Hereby it will be possible for the unit together with the control unit to make compensatory adjustments of the cutting height in relation to variations in terrain height in the cutting area.

Ved aktuatoren 30 der er forbundet med den U-formede konsol 16, vil der være mu-20 lighed for at foretage drejning af denne omkring den vertikale akse 14 ved drejefor-bindelsen 13. Herved vil der være mulighed for kompenserende drejninger af den U-formede konsol 16, i tilfælde af at dennes, ved den roterbare lejring 48 maximale vin-keldrejning beliggende i intervallet 0-180°, ikke er tilstrækkeligt i en given klippeopgave. Aktuatoren 30 og drejeforbindelsen 13 har endvidere en yderligere funktion der 25 forklares senere.At the actuator 30 connected to the U-shaped bracket 16, there will be the possibility of rotating it about the vertical axis 14 at the rotary connection 13. This will allow for compensating rotations of the U-shaped bracket. shaped bracket 16, in case its rotational bearing 48 maximum angular rotation located in the range 0-180 ° is not sufficient in a given cutting task. The actuator 30 and the pivot joint 13 further have an additional function which is explained later.

Som det endvidere fremgår af fig. 5 er bærearmen 10 svingbart lejret omkring en i hovedsagen horisontalt orienteret akse 52 til en bæreenhed 54, ved drejeenhed 58 drevet af en drivenhed 56, der ligeledes er tilsluttet/reguleret via styreenheden 40. Denne 30 funktion medfører en vis fleksibilitet med hensyn til vinkeldxejning af den U-formede konsol 16 i forhold til vandret, hvilket kan være af stor betydning i tilfælde hvor klip-peområdet skråner i forhold til kørebanen på hvilket køretøjet 3 befinder sig, men også denne drejeenhed 58 har en yderligere funktion, der forklares senere.Furthermore, as can be seen from FIG. 5, the support arm 10 is pivotally mounted about a generally horizontally oriented axis 52 to a support unit 54, at pivot unit 58 driven by a drive unit 56 which is also connected / controlled via the control unit 40. This function provides some flexibility with respect to angular extension of the U-shaped bracket 16 relative to the horizontal, which can be of great importance in cases where the clipping area slopes with respect to the roadway on which the vehicle 3 is located, but also this turning unit 58 has an additional function which will be explained later.

Som det fremgår af fig. 1 og fig. 2 udgøres bæreenheden 54 af en ved en hydraulikmotordrevet tandstangsforbindelse 59, tværforskydelig bom 60, i hvis forskydelige ende 62, bærearmen 10 er monteret, og hvilken forskydelig bom 60 omfatter standardkoblingsmidler 64 for montering på et arbejdskøretøj, fortrinsvis en traktor, jf., fig. 9A.As shown in FIG. 1 and FIG. 2, the carrier unit 54 is constituted by a hydraulic motor gear rack 59, a slidable boom 60, with its slidable end 62, the carrier arm 10 mounted, and which slidable 60 comprises standard coupling means 64 for mounting on a working vehicle, preferably a tractor, cf. 9A.

5 Nævnte standardkoblingsmiddel udgøres i den viste udførelsesform af en med en A-ramme på en traktor, samvirkende ramme.Said standard coupling means is, in the illustrated embodiment, a cooperating frame having an A-frame on a tractor.

Som det fremgår af lig. 6 og fig. 7 er den tværforskydelige bom 60 ved en drejeforbin-delse 66 er lejret svingbart omkring en horisontalt orienteret akse 68, nær standardkob-10 lingsmidlerne 64 for montering på et arbejdskøretøj, I den viste udførelsesform udgøres drejeforbindelsen 66 af en på den tværforskydelige bom 60 vertikalt orienteret tandkrans 70, hvis tænder 72 står i forbindelse med et tandhjul 74 på en på standardkoblingsmidlerne 64 monteret, og af en drivenhed 76, der i den viste udførelsesfonn udgøres af en hydraulikmotor, roterbar drevet drivakse] 78. Ved denne foranstaltning 15 bliver det muligt at foretage et skift af placeringen af arbejdsside for aggregatet 2 i forhold til køretøjets kørselsretning A. Omskiftningen bliver naturligvis lettet af at denne kan udføres ved aktivering af hydraulikmotoren 76, via styreenheden 40.As shown by corpses. 6 and FIG. 7, the transverse boom 60 at a pivot joint 66 is pivotally mounted about a horizontally oriented axis 68, near the standard coupling means 64 for mounting on a working vehicle. In the embodiment shown, the pivot joint 66 is constituted by a vertically oriented transverse boom 60. gear ring 70, the teeth of which 72 communicate with a gear 74 on one mounted on the standard coupling means 64, and by a drive unit 76, which in the illustrated embodiment is constituted by a hydraulic motor, rotatable driven drive shaft] 78. By this measure 15 it is possible to make a change of position of the working side of the unit 2 in relation to the direction of travel of the vehicle A. The switching is of course facilitated by the fact that this can be done by activating the hydraulic motor 76, via the control unit 40.

Imidlertid ville en svingning af den iværforskydelige bom 60 på 180° medføre at bærearmen 10 ville være orienteret bort fra underlaget 5, men her udnyttes således dreje' 20 enheden 58, ved hvilken bærearmen 10, og dermed bærerammen for den U-formede konsol 16, med klippehovederne kan svinge omkring en horisontalt orienteret akse 52, jf. fig. 5, således at klippehovederne 22, 24, 32 orienteres imod underlaget 5.However, a pivoting of the 180 ° retractable boom 60 would cause the support arm 10 to be oriented away from the support 5, but utilizing here turns the unit 58 at which the support arm 10, and thus the support frame for the U-shaped bracket 16, with the cutting heads may pivot about a horizontally oriented axis 52, cf. 5, so that the cutting heads 22, 24, 32 are oriented against the substrate 5.

Svingningen vil imidlertid medføre at den U-foraiede konsol 16 vil være orienteret 25 således at dennes ben er orienteret imod kørselsretningen A, hvilket er uhensigtsmæssigt, og her udnyttes aktuatoren 30, der via styreenheden 40 aktiveres, hvorved den U-formede konsol drejes imellem 0°-180° omkring den vertikale akse 14 ved drejefor-bindelsen 13, hvorved aggregatet ifølge opfindelsen på et øjeblik er operationsklar på den modsatte side af køretøjet 3 i forhold til dettes kørselsretning A 30However, the oscillation will cause the U-shaped bracket 16 to be oriented 25 such that its legs are oriented against the direction of travel A, which is inappropriate, and here the actuator 30 is actuated, which is activated via the control unit 40, thereby turning the U-shaped bracket between 0 ° -180 ° about the vertical axis 14 of the pivot joint 13, whereby the assembly according to the invention is momentarily ready for operation on the opposite side of the vehicle 3 relative to its direction of travel A 30

Aggregatet kan endvidere på bærearmen 10 omfatte en tredje sensorenhed 80, jf., fig.The assembly may further comprise on the support arm 10 a third sensor unit 80, cf.

5, for detektering af kantafgrænsningen 8 af underlaget 5. Sensorenheden 80 er via aggregatets styreenhed 40 er forbundet med hydrauliskmotoren 59, på den tværforsky 13 DK 176811 B1 delige bom 60, hvorved der nu automatisk kan udføres kompensering af den siderettede placering afbærerammen 12 og dermed den U-formede konsol 16 med klippehovederne 22,24,26 i forhold til kantafgrænsningen 8.5, for detecting the edge boundary 8 of the base 5. The sensor unit 80 is connected via the control unit 40 of the unit to the hydraulic motor 59, on the transverse beam 13, which can now automatically compensate for the lateral position of the carrier frame 12 and thus the U-shaped bracket 16 with the cutting heads 22,24,26 relative to the edge boundary 8.

5 Der er ved aggregatet 2 ifølge opfindelsen, tilvejebragt et yderst effektivt virkende redskab for montering på A-rarmnen på forenden af en traktor 3, på hvis liftindretning bagtil, kan være forsynet med en klippeenhed 100 på en arm 102. der ligeledes ved en særlig styreenhed kan bringes til at klippe bevoksningen udenfor klippeområdet for aggregatet, således at operatøren af traktoren i hovedsagen skal koncentrere sig om at 10 styre traktoren langs siden af vejen hvis rabatters bevoksninger skal klippes. Aggregatet kan tillige tjene som erstatning for den ballast, der alligevel skulle tjene som modvægt i forhold til klippeaggregatet bagerst på traktoren.An extremely effective tool for mounting on the A-frame on the front end of a tractor 3, on whose rearward lifting device, may be provided with a mowing unit 100 on an arm 102. control unit can be caused to mow the grove outside the mowing area of the unit, so that the operator of the tractor in the main event must concentrate on steering the tractor along the side of the road if the stands of mowers are to be cut. The unit can also serve as a replacement for the ballast, which should nonetheless serve as a counterweight to the mower at the rear of the tractor.

Aggregatet rummer tillige yderligere muligheder, eksempelvis kan dette i en ikke vist 15 udførelsesform omfatte udstyr til vask af kantpælene langs vejen, hvorom aggregatet klipper bevoksningen 4. Vaskeudstyret kan udgøres af en i forhold ril bærerammen 12, og i bæreamiens længderetning selvstændigt forskydeligt lejret og ved en aktuator forskydelig konsol, omfattende i det mindste to parallelt orienterede, udstående, fortrinsvis horisontalt orienterede, roterbart lejrede aksler, der ved drivenheder bringes til 20 rotation, på hvilke aksler findes børster, samt i det mindste en dyse for udsprøjtning af vand under tryk, tilført fra et på køretøjet forråd, i børsteområdet.The assembly also provides additional possibilities, for example, in an embodiment not shown, this may include equipment for washing the edge piles along the road through which the unit cuts the vegetation 4. The washing equipment can be constituted by a relatively frame bearing frame 12 and in the longitudinal direction of the carrier independently displaceable and at an actuator slidable bracket, comprising at least two parallel oriented, protruding, preferably horizontally oriented, rotatably mounted shafts brought to rotation by drive units on which shafts are provided, and at least one nozzle for spraying water under pressure, supplied from a vehicle storage facility, in the brush area.
