Redskapsfåstet utmårks särskilt av ett på redskapsfåstet uppburet drivorgan för drivning av ett tillkopplat redskap. i Uppfinningen beskrivs närmare nedan i anslutning till bilagda ritningar, Vafi Fig. l visar ett arbetsfordon med redskapsfâsten enligt uppfinningen kopplade i en fråmre lyftarm såväl som i en baktill på fordonet uppburen gråvarm; Fig. 2 visar redskapsfåstet i en perspektivvy, och Fig. 3 visar ett alternativt inrättat redskapsfåste i en fig. 2 motsvarande perspektiv- Vy. 527,950 bodies for alternative connection to different types of work tools. The tool holder is marked in particular by a drive means supported on the tool holder for driving a coupled tool. i The invention is described in more detail below in connection with the accompanying drawings, Vafi Fig. 1 shows a work vehicle with implement brackets according to the invention connected in a front lifting arm as well as in a gray heat supported at the rear of the vehicle; Fig. 2 shows the tool holder in a perspective view, and Fig. 3 shows an alternatively arranged tool holder in a fi g. 2 corresponding perspective- View.

Redskapsfåstet enligt uppfinningen innefattar en bärande ram med en fordonssida och en redskapssida. På fordonssidan år åtminstone ett kopplingsorgan anordnat för löstagbar montering av redskapsfåstet på ett arbetsfordon, såsom en traktor utrustad med frontlastare, trepunktsfåste eller grâvarm, eller alternativt en gräv- maskin. På redskapssidan år likaledes åtminstone ett kopplingsorgan anordnat för löstagbar montering av ett redskap på redskapsfåstet. Detta kopplingsorgan är lämpligen ett trepunktsfâste, ett frontlastarfâste, eller annat fäste för löstagbar koppling av ett redskap. Företrådesvis innefattar både fordonssidan och redskaps- sidan minst två kopplingsorgan för altemativt utnyttjande av olika redskap och av olika arbetsfordon. ' I den i fig. 1-3 visade utföringsforrnen uppvisar redskapsfåstet en lådliknande bår- ram 1 med ett par motstående vertikala sidostycken 2 respektive 3, vilka i sina ned- re ändar förbinds genom ett horisontellt bottenstycke 4 och i sina övre ändar av ett horisontellt överstycke 5. Bårramens sidostycken, botten- och överstycken år här visade som plattor av stål vilka år sammansvetsade i bårramens hörn. Bårrarnen år utformad för att uppbära nedan beskrivna kopplingsorgan och kan ges annan kon- struktiv utformning än den visade, såsom en fackverkskonstruktion eller balkkon- struktion, utan att uppfmningstanken därför överges. 527 950 I en till ett arbetsfordon kopplingsbar sida av bårramen 1 år ett första fordonskopp- lingsorgan anordnat i form av ett par krokar 6 (varav endast den ena år synlig i rit- ningsfiguren) och sprintgenomföringar 7 fór koppling av redskapsfåstet till samver- kande organ pålyftarmen av en frontlastare. Ett andra fordonskopplingsorgan i form av ett tvåaxligt fäste, en så. kallad grind eller ett grindfäste 8 år anordnat på överstyckets ovansida för koppling av redskapsfästet till grävarmen av en grävlasta- re eller en grävmaskin. Fästet 8 kan alternativt vara anordnat direkt på överstycket 5 eller indirekt genom en mellankopplad vridled 9, varmed bärramen 1 kan lutas i valfri riktning runt ledens vridaxel 10. Lutningslâget år med fördel dynamiskt in- ställbart med hjälp av åtminstone en hydraulcylinder ll som ingriper mellan bâr- ramen, eller dess överstycke 5, och ett fäste 12 tillhörande den vridbara del som uppbär grindfästet 8. I en alternativ utfóringsform kan istället för hydraulcylin- dem / hydraulcylindraxna ll ett eller två till sin längd inställbara stag 1 l' vara an- ordnade mellan bârramen och fästet 12 för en statisk inställning av ett lutningslä- ge.The tool holder according to the invention comprises a supporting frame with a vehicle side and a tool side. On the vehicle side, at least one coupling means is arranged for detachable mounting of the implement bracket on a work vehicle, such as a tractor equipped with a front loader, three-point hitch or excavator, or alternatively an excavator. On the tool side, at least one coupling member is also arranged for detachable mounting of a tool on the tool holder. This coupling means is suitably a three-point bracket, a front loader bracket, or other bracket for detachable coupling of an implement. Preferably, both the vehicle side and the implement side comprise at least two coupling means for alternative use of different implements and of different work vehicles. 'I den i fi g. 1-3, the tool holder has a box-like support frame 1 with a pair of opposite vertical side pieces 2 and 3, respectively, which are connected at their lower ends by a horizontal bottom piece 4 and at their upper ends by a horizontal top piece 5. The side pieces of the support frame, bottom and top pieces of years here showed as steel plates which years welded together in the corners of the stretcher frame. The stretchers are designed to support the coupling members described below and can be given a constructive design other than the one shown, such as a truss construction or beam construction, without the idea of invention being abandoned. 527 950 In a side of the stretcher frame which can be connected to a work vehicle, a first vehicle coupling member is arranged in the form of a pair of hooks 6 (of which only one year is visible in the drawing)) and pin bushings 7 for coupling the tool holder to cooperating means. the lifting arm of a front loader. A second vehicle coupling means in the form of a two-axle bracket, a so. called a gate or a gate bracket 8 years arranged on the upper side of the upper part for connecting the tool bracket to the digging arm of a backhoe loader or an excavator. The bracket 8 can alternatively be arranged directly on the upper piece 5 or indirectly through an intermediate coupled pivot joint 9, with which the support frame 1 can be tilted in any direction around the pivot axis of the pivot 10. The inclination position is advantageously dynamically adjustable by means of at least one hydraulic cylinder 11 - the frame, or its upper piece 5, and a bracket 12 belonging to the rotatable part which supports the gate bracket 8. In an alternative embodiment, instead of hydraulic cylinders / hydraulic cylinder axes ll, one or two length-adjustable struts 1 l 'can be arranged between the support frame and bracket 12 for a static adjustment of a tilt position.

I en till ett redskap kopplingsbar sida av bårramen l år' ett första redskapskopp- lingsorgan i form av ett frontlastarfäste anordnat och innefattande ett par sprintar 13 samt ett par öglor 14, 14' med genomgående sprintar 15. Ett andra redskaps- kopplingsorgan i form av ett trepunktsfäste innefattande armar 16 vilka i sina inre och med öglor formade ändar är ledbart uppbuma på sprintania 15, och vilka på konventionellt sätt är förankrade i bärramen, exempelvis i bârramens sidostycken medelst stag, såsom de illustrerade förlängningsbara stagen 17. 'Pill trepunksfâstet hör även ett par öglor 18 anordnade i framkant av redskapsfä-stets överstycke 5 för ' genomföring av en sprint ( sprinten är ej visad).In a side of the support frame which can be coupled to an implement 1 'is a first implement coupling member in the form of a front loader bracket arranged and comprising a pair of pins 13 and a pair of loops 14, 14' with continuous pins 15. A second tool coupling member in the form of a three-point bracket comprising arms 16 which in their inner and loop-shaped ends are hingedly supported on the sprint 15, and which are conventionally anchored in the support frame, for example in the side pieces of the support frame by means of struts, such as the illustrated extendable struts 17. The pill three-point bracket also belongs a pair of loops 18 arranged in the leading edge of the tool holder top 5 for performing a sprint (the pin is not shown).

Väl skyddat inuti bårramen 1 är ett drivorgan 19 anordnat för drivning av ett red- skap som är kopplat till ett av redskapskopplingsorganen. Drivorganet 19 utgörs med fördel av en via arbetsfordonets hydraulsystem driven hydraulrnotor med en utgående drivaxel 20 för drivning av exempelvis snöslungor, slåtteraggregat eller annat arbetande redskap, uppburet i något' av redskapskopplingsorganen. Drivor- ganet kan alternativt ha annan försörjning såsom pneumatisk eller elektrisk, och kan exempelvis utgöras av en elektriskt försörjd servomotor. 527 950 Med hänvisning till fig. 3 visas en i redskapsfästet ingående sprint 15. Sprinten 15 uppvisar ett huvud från vilket sträcker sig ett första axiellt parti 15' med en första diameter utformad för att bilda en i ett frontlastarfäste ingående komponent. Från nämnda första axiella parti av sprinten 15 sträcker sig vidare ett andra axiellt parti 15” med en andra och mindre diameter utformad för lagring av en i ett trepunkts- fäste ingående arm 16. För mottagning av sprinten 15 uppvisar bårramen 1 tre fåstöron 14, 14' och 14” med gemensamt inriktade hål. Hålen i ett första och andra fästöra 14, 14' uppvisar en gemensam diameter motsvarande diametern av det för- sta axiella partiet 15' av sprinten 15, och det tredje fâstörat 14” uppvisar en mindre diameter motsvarande diametem av det andra axiella partiet 15” av sprinten 15.Well protected inside the stretcher frame 1, a drive means 19 is arranged for driving an implement which is connected to one of the implement coupling means. The drive means 19 is advantageously constituted by a hydraulic motor driven via the hydraulic system of the work vehicle with an output drive shaft 20 for driving, for example, snow throwers, mowing units or other working implements, supported in one of the implement coupling means. The drive member may alternatively have another supply, such as pneumatic or electric, and may, for example, consist of an electrically supplied servomotor. 527 950 With reference to fi g. 3 shows a pin 15 included in the implement bracket. The pin 15 has a head from which extends a first axial portion 15 'with a first diameter designed to form a component included in a front loader bracket. Extending from said first axial portion of the pin 15 is further a second axial portion 15 "with a second and smaller diameter designed for storage of an arm 16 included in a three-point bracket. For receiving the pin 15, the support frame 1 has three sheep ears 14, 14. 'and 14 ”with commonly aligned holes. The holes in a first and second mounting lugs 14, 14 'have a common diameter corresponding to the diameter of the first axial portion 15' of the pin 15, and the third mounting lugs 14 "have a smaller diameter corresponding to the diameter of the second axial portion 15" of sprint 15.

Genom sin utfonnning tillhandahåller redskapsfästet enligt uppfinningen en förhöjd nyttjandegrad av arbetsfordon och redskap, och möjliggör obegränsad valfrihet att koppla varje redskap antingen till arbetsfordonets front eller akter, oaktat om for- donet år utrustat med lastare eller grävarm. Likaså medger redskapsfästet enligt uppfinningen samtidigt utnyttjande av olika eller samverkande redskap kopplade både till fordonets front och akter, såsom illustreras i fig. 1. Härigenom ökas inte endast fordonsparkens flexibilitet, utan även arbetskapaciteten genom att exempel- vis dubbla slåtteraggregat eller snöslungor kan framföras samtidigt med ett och samma fordon vars arbetsbredd på detta sätt kan fördubblas under ett och samma moment.Through its design, the tool holder according to the invention provides an increased degree of utilization of work vehicles and tools, and enables unlimited freedom of choice to connect each tool to either the front or stern of the work vehicle, regardless of whether the vehicle is equipped with a loader or digging arm. Likewise, the tool holder according to the invention allows the simultaneous use of different or cooperating tools connected to both the front and aft of the vehicle, as illustrated in fi g. 1. This increases not only the vehicle fleet 'fl flexibility, but also the working capacity by, for example, double mowing units or snow throwers can be driven simultaneously with one and the same vehicle whose working width can be doubled in this way during one and the same moment.
