Opfindelsen angår et renseredskab omfattende en væskeudløbsåbning eller dyse i forbindelse med en kanal, der kan tilføres væske under tryk, samt et løsgøringsorgan 5 omfattende mindst en del, der rager frem på den side af åbningen eller dysen, hvor væsken løber ud.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a cleaning tool comprising a liquid outlet opening or nozzle in connection with a channel which can be supplied with pressurized liquid, and a release means 5 comprising at least a part projecting on the side of the opening or nozzle where the liquid flows out.

Fra US-patentskrift nr. 1.598.811 kendes der en sådant redskab med et spartel- eller spadelignende formet skrabeorgan og indrettet således, at dysen kan sende en 10 stråle henover skrabeorganets over- og/eller underside rettet ind mod organets forkant. Væsken, der udsendes over skrabeorganet i en bred vifte, har alene til formål at blødgøre og bortskylle forholdsvis små og løstsiddende urenheder, f.eks. på en vinduesrude. Snavs skrabes af 15 overfladen ved hjælp af skrabeorganet. Strålen bidrager ikke ved denne proces, men først ved efterfølgende bortspuling af det helt eller delvis løsnede snavs.From U.S. Pat. No. 1,598,811, such a tool is known with a putty or spade-like shaped scraper and arranged so that the nozzle can send a beam across the top and / or underside of the scraper towards the leading edge of the member. The liquid dispensed over the scraper means in a wide range is solely for the purpose of softening and flushing relatively small and loose impurities, e.g. on a window pane. Dirt is scraped off the surface by the scraper. The beam does not contribute to this process, but only to subsequent rinsing of the partially or completely loosened dirt.

Desuden kendes der fra US-patentskrift nr. 4.736.805 en hydraulisk slagmejsel, hvor der inden i en rørformet 20 mejsel tilføres væske under tryk. Materialet nedbrydes med en kombinationsvirkning mellem mejslen og trykstrålen, idet trykstrålen indledningsvis tilføjer materialet revnedannelser i overfladen, hvorefter mejslen ved en hydraulisk drevet slagbevægelse knuser og opbryder 25 materialet. Slagmejslen er anvendt i granitbrud og lignende.Furthermore, from US Patent No. 4,736,805, a hydraulic impactor is known, in which fluid is pressurized within a tubular chisel. The material is decomposed with a combination effect between the chisel and the pressure jet, the pressure jet initially introducing cracks in the surface, after which the chisel crushes and breaks the material by a hydraulically driven stroke. The chisel is used in granite quarries and the like.

Fra US-patentskrift nr. 1.525.571 kendes en gravegreb, hvor der mellem grenene er monteret dyser for udstråling af vand ved forholdsvis lavt tryk og for blødgøring af den 30 jord, hvori der graves.US Patent No. 1,525,571 discloses a trench where nozzles are mounted between the branches to radiate water at relatively low pressure and to soften the soil in which it is being dug.

Endelig kendes der fra US-patentskrift nr. 1.747.258 et skovllignende redskab, hvori der ved bladets endekant er udformet åbninger for udsendelse af trykluft.Finally, from U.S. Pat. No. 1,747,258, a bucket-like tool is known in which openings for the discharge of compressed air are formed at the end edge of the blade.

Formålet med opfindelsen er at anvise et enkelt redskab, der på effektiv måde kan fjerne fastsiddende lag fra en mellemhård overflade, f.eks. fasttrampet kage af stald-5 gødning og halm m.v. fra et betongulv, ved at kombinere virkningen af en højtryksstråle med et brækjernlignende redskab.The object of the invention is to provide a single tool which can effectively remove stuck layers from a medium hard surface, e.g. firmly-stepped cake of barn-5 manure and straw, etc. from a concrete floor, by combining the action of a high-pressure jet with a brittle-iron tool.

Det opnås ifølge opfindelsen med et redskab af ovennævnte art, der er ejendommeligt ved, at løsgøringsorganet har 10 mindst to tænder eller grene, der er placeret på hver sin side af dysen og rager frem foran denne at grenene er udformet og dysen placeret således i forhold til disse, at en væskestråle fra dysen rammer en plan flade i et punkt inden for den omskrevne cirkel for grenendernes anlægs-15 punkter mod fladen, og at der i en afstand før grenenes frie ender på redskabet er udformet en understøtningsflade, der er således forsat i forhold til grenspidserne og redskabets længdeakse, at understøtningsfladen kan hvile mod underlaget ved vipning af grenspidserne under 20 udnyttelse af vægtstangsprincippet.It is achieved according to the invention with a tool of the above-mentioned nature, characterized in that the detaching means has at least two teeth or branches which are located on either side of the nozzle and protrude in front of it that the branches are formed and the nozzle is positioned thus in proportion. to these, that a jet of liquid from the nozzle strikes a flat surface at a point within the circumscribed circle of the abutment abutment points towards the surface, and that a support surface is formed at a distance before the free ends of the tool. in relation to the branch points and the longitudinal axis of the implement, that the supporting surface can rest against the substrate by tilting the branch points below 20 utilization of the lever principle.

Under anvendelse af redskabet ifølge opfindelsen tilsluttes redskabet en kilde for væske under højt tryk og tænderne føres under en skrå vinkel frem over den hårde overflade og ind under det materialelag, der skal fjernes.Using the tool of the invention, the tool is connected to a source of high pressure liquid and the teeth are advanced at an inclined angle over the hard surface and under the material layer to be removed.

25 Herved kiler grenene eller tænderne sig ind under laget, der løftes lidt. Der er således skabt adgang for væskestrålen, der mellem grenene kan trænge ind mellem laget og overfladen og med sin mekaniske kraft rive laget af. Det viser sig, at fasttrampede affaldskager kan fjernes fra et 30 betongulv på denne måde, hvilket ellers ikke har være muligt uden lufthamre. Andre formål end rengøring kunne også tænkes, idet fjernelse af f.eks. asfaltlag på betonunderlag kunne være en relevant udnyttelse af opfindelsen. Understøtningsfladen hviler mod underlaget 35 ved vipning af grenspidserne under udnyttelse af vægtstangsprincippet, således at redskabet fungerer som en 3 DK 167381 B1 art brækjern.25 In this way the branches or teeth wedge under the layer which is lifted slightly. Access has thus been created for the liquid jet, which between the branches can penetrate between the layer and the surface and with its mechanical force tear off the layer. It turns out that solid trash cakes can be removed from a concrete floor in this way, which otherwise would not be possible without air hammering. Purposes other than cleaning could also be conceived, removing e.g. asphalt layers on concrete substrates could be a relevant use of the invention. The support surface rests against the substrate 35 by tilting the boundary tips utilizing the lever principle, so that the implement acts as a fracture iron.

Understøtningsfladen kan ifølge opfindelsen være udformet og placeret således i forhold til grenspidserne, at den 5 kan glide hen over underlaget, medens grenspidserne ledes frem gennem skidtlaget. Herved opnås en sikker styring af grenspidserne med mindst mulig indsats fra operatørens side.According to the invention, the support surface can be designed and positioned relative to the boundary points so that it can slide across the substrate while the boundary points are advanced through the dirt layer. This ensures safe control of the branch points with the least effort on the part of the operator.

En enkel konstruktion, der er velegnet til montering på de 10 velkendte højtryksrensere, er ejendommelig ved, at løsgøringsorganet omfatter en bøsning, hvis ene ende er fastgjort til et spulerør, og i hvis anden ende spuledysen er fastgjort. Over for hinanden er anbragt to grene på bøsningen, som strækker sig frem foran spuledysen og 15 beregnet til at skrabe skidtet løs. Grenenes frie ender er hensigtsmæssigt skråt afskårne i en vinkel, så enderne glider på underlaget i brugsstillingen. Grenene glider dermed lettere over underlaget og kiler med spidserne lettere ind under skidtet.A simple structure suitable for mounting on the 10 well-known high-pressure cleaners is characterized in that the release means comprises a bushing, one end of which is fixed to a flushing pipe and at the other end of which the flush nozzle is fixed. Opposite to each other are placed two branches on the bush, which extends in front of the coil nozzle and 15 intended to scrape the dirt off. Conveniently, the free ends of the branches are cut at an angle so that the ends slide on the support in the position of use. The branches thus slide more easily over the ground and wedge with the tips more easily under the dirt.

20 Den praktiske udformning af løsgøringsorganet og placeringen af dysen kan laves på mange forskellige måder, eksempelvis kan løsgøringsorganet blot være et pladestykke med en udstansning, så der dannes to grene, og dysen kan være placeret på den ene side af pladestykket.The practical design of the release member and the location of the nozzle can be made in a variety of ways, for example, the release member may simply be a plate piece with a die cut to form two branches and the nozzle may be located on one side of the plate piece.

25 Organet kan også have flere grene eller horn, ligesom væskestrålen ikke nødvendigvis behøver at være akseparallel med løsgøringsorganet.The member may also have multiple branches or horns, just as the fluid jet does not necessarily have to be axis parallel to the release member.

I det følgende skal der under henvisning til medfølgende tegning beskrives et udførelseseksempel for opfindelsen.In the following, an embodiment of the invention will be described with reference to the accompanying drawing.

30 På tegningen viser fig. 1 et redskab ifølge opfindelsen set forfra, fig. 2 redskabet som i fig. 1 set fra siden med den ene flæne delvis fjernet, og fig. 3 en grenspids med tilhørende understøtningsflade.30 In the drawing, FIG. 1 is a front view of a tool according to the invention; FIG. 2 the tool as in FIG. 1 is a side view of the one lawn partially removed, and FIG. 3 shows an intersection tip with associated support surface.

Det på tegningen viste udførelseseksempel for redskab med et gaffelformet skrabeorgan er specielt beregnet til brug i forbindelse med en sædvanlig højtryksrenser. Skrabe-5 organet er specielt udformet til løsning af fastgroet husdyrmøg som grise- og komøg, som undertiden kan være så fastgroet til gulvet, at det kan være nødvendigt med anvendelse af lufthamre med spadeværktøj for at fjerne det.The exemplary embodiment of a tool with a fork-shaped scraper shown in the drawing is specially designed for use in conjunction with a conventional high-pressure cleaner. The scraper 5 is specially designed for the solution of firmly grazed livestock dung such as pig and cow dung, which may sometimes be so firmly rooted to the floor that the use of air hammer with spade tool may be necessary to remove it.

10 Udførelseseksemplet ifølge opfindelsen omfatter et spulerør 1, der på den ikke viste ende er forsynet med en kobling med højtryksrenserens håndtag. For at opnå en bekvem arbejdsstilling er spulerøret ved dets anden ende givet et knæk. Denne anden ende er påskruet en bøsning 2.The embodiment of the invention comprises a flushing tube 1 provided at the end not shown with a coupling with the handle of the high-pressure cleaner. In order to obtain a comfortable working position, the washer at its other end is cracked. This other end is screwed on a socket 2.

15 I bøsningen er der fastgjort en spuledyse 3. På bøsningens side er der diamentralt over for hinanden fastgjort to flæner 4, der trækker sig forbi dysen 3. Flænernes ender 5 er skråt afskåret beregnet til at glide hen over underlaget, der skal renses. Flænen 4 er givet en vinkel 20 fremefter i forhold til dysens stråleretning, så strålen fra dysen rammer umiddelbart bag flænerne, når redskabet føres hen mod det materialelag, der skal fjernes.15 A bushing nozzle 3 is attached to the sleeve. On the sleeve side two flanges 4 are diametrically attached to each other, which extend past the nozzle 3. The ends 5 of the flanges are inclined cut to slide over the substrate to be cleaned. The flange 4 is given an angle 20 forward with respect to the jet direction of the nozzle, so that the jet from the nozzle strikes immediately behind the flanges as the tool is moved toward the material layer to be removed.

En fordel ved denne udformning af opfindelsen er, at stråleviften rammer flænerne 4 og bøjes opad, hvorved der 25 opstår et tryk opad på undersiden af laget, der skal fj ernes.An advantage of this embodiment of the invention is that the beam fan strikes the flanges 4 and bends upwards, thereby producing an upward pressure on the underside of the layer to be removed.

I fig. 3 er der vist en udførelsesform, hvor en slidbestandig understøtningsflade 6, dels kan tjene som understøtningsflade, når grenspidserne vippes som ved en 30 brækjernsbevægelse, dels tjene som glideflade ved fremføring af grenspidserne over underlaget.In FIG. 3, there is shown an embodiment in which a wear-resistant support surface 6 can serve partly as a support surface when the interfaces are tilted as in a fracture-iron movement and partly as a sliding surface when advancing the interfaces above the substrate.
