Opfindelsens områdeFIELD OF THE INVENTION
Den foreliggende opfindelse angår et koblingsarrangement mellem et køretøj og et redskab, hvor der i forbindelse med køretøjet er tilvejebragt et flerpunktsarrangement, der omfatter mindst en øvre koblingsdel og et antal nedre koblingsdele, hvor der i for-5 bindelse med redskabet er tilvejebragt et trepunktsarrangement, der omfatter mindst en øvre koblingsdel, og mindst to nedre koblingsdele, og hvor et antal koblingsarme og et antal længdejusterbare forbindelsesstænger forbinder nævnte trepunktsarrangement og nævnte flerpunktsarrangement, 10 Opfindelsens baggrundThe present invention relates to a coupling arrangement between a vehicle and a tool, in which a multi-point arrangement is provided which comprises at least one upper coupling part and a plurality of lower coupling parts where a three-point arrangement is provided in connection with the vehicle. comprising at least one upper coupling member and at least two lower coupling members, and wherein a plurality of coupling arms and a plurality of length adjustable connecting rods connect said three-point arrangement and said multi-point arrangement, Background of the Invention
Ved at koble redskaber til et køretøj, fortrinsvis en traktor, anvendes der i dag generelt trepunktsophængsarrangementer, såfremt redskabet er af en vis størrelse og/eller skal hæves/sænkes under driften. Fordelen ved at anvende et trepunktsophæng er, at redskabet kan fastholdes i både en forudbestemt lodret og vertikal position.By coupling implements to a vehicle, preferably a tractor, three-point suspension arrangements are generally used today if the implement is of a certain size and / or must be raised / lowered during operation. The advantage of using a three-point suspension is that the implement can be held in both a predetermined vertical and vertical position.

Ved at anvende trepunktsophæng i forbindelse med kobling af et redskab til en traktor er det muligt at koble for eksempel en skrabeplade, en tromle, en harve eller et lignende jordbearbejdningsredskab til en traktor.By using three-point mounts in connection with coupling an implement to a tractor, it is possible to connect, for example, a scraping plate, drum, harrow or similar tillage tool to a tractor.
20 Disse redskaber er afhængige af, at traktoren under transport og i andre situationer kan løfte redskabet op fta jorden. Når redskabet skal anvendes på/i jorden, kan redskaberne på grund af deres egenvægt bearbejde jorden i en ønsket dybde eller med et ønsket tryk.20 These implements are dependent on the tractor being able to lift the implement up and down in other situations. When the tool is to be used on / in the ground, the tools can, due to their weight, work the soil at a desired depth or with a desired pressure.
25 Dette kan være en ulempe, fordi redskaberne eller dele deraf skal have en høj vægt eller en stor udstrækning for at kunne tvinge den jordbearbejdende del af redskabet ned i jorden eller danne det ønskede nedadrettede tryk. Dette medfører, at redskaberne bliver meget tunge og kræver derfor større kraft for at kunne køre.This can be a disadvantage because the tools or parts thereof must have a high weight or a large extent in order to force the soil-working part of the implement into the ground or to produce the desired downward pressure. This means that the tools become very heavy and therefore require greater force to run.
30 Samtidig er det et ønske fra branchen, at redskaberne skal være meget brede, således at man undgår at køre henover markerne alt for mange gange.30 At the same time, it is a wish of the industry that the tools must be very wide, so as to avoid crossing the fields too many times.
DK 176105 B1 2DK 176105 B1 2
Kombinationen af ovennævnte gør, at traktorerne bliver store, hvilket kan være en ulempe, da der kan opstå traktose i hjulsporene efter traktorerne, hvilket medfører, at jorden i hjulsporene bliver mindre frugtbar end den omliggende jord.The combination of the above causes the tractors to become large, which can be a disadvantage as tractose can occur in the wheel tracks after the tractors, which causes the soil in the wheel tracks to become less fertile than the surrounding soil.
5 Fra US-4.448.274 kendes et koblingsarrangement, hvor der er anbragt et antal længde-justerbare forbindelsesstænger mellem køretøjet og redskabet. Dette koblingsarrangement medfører, at en del af køretøjets vægt overføres til redskabet og derved udøver en nedadgående kraft fra køretøjet til redskabet.From US-4,448,274 there is known a coupling arrangement in which a number of length-adjustable connecting rods are arranged between the vehicle and the implement. This coupling arrangement causes a portion of the weight of the vehicle to be transferred to the implement, thereby exerting a downward force from the vehicle to the implement.
10 Der er dog ulemper forbundet med dette koblingsarrangement. Dels er det muligt både at forlænge og forkorte de længdejusterbare forbindelsesstænger, hvilket kræver en forholdsvis indviklet styremekanisme, der kan synkronisere sammentrækningen og/eller forlængelsen af de førnævnte længdejusterbare forbindelsesstænger. Dels er der risiko for, at koblingsarmene eller det første trepunktsarrangement deformeres 15 eller ødelægges, hvis der anvendes for stor kraftoverførsel ved forlængelse af førnævnte længdejusterbare forlængelsesstang. Desuden er opfindelsen begrænset til kobling af to trepunktsarrangementer.10 However, there are disadvantages associated with this coupling arrangement. In part, it is possible to both extend and shorten the length adjustable connecting rods, which requires a relatively complicated control mechanism capable of synchronizing the contraction and / or extension of the aforementioned length adjustable connecting rods. Partly, there is a risk that the coupling arms or the first three-point arrangement will be deformed or damaged if excessive force transfer is used when extending the aforementioned length-adjustable extension rod. Furthermore, the invention is limited to the coupling of two three-point arrangements.
Opfindelsens formål 20 Formålet med den foreliggende opfindelse er at anvise et koblingsarrangement mellem et redskab og et køretøj, som gør det muligt på en simpel måde at overføre en nedadgående kraft fra køretøjet til redskabet, og som kan kontrolleres ved hjælp af en simpel styremekanisme.Objects of the Invention The object of the present invention is to provide a coupling arrangement between an implement and a vehicle which allows a simple way of transmitting a downward force from the vehicle to the implement and which can be controlled by a simple steering mechanism.
25 Dette formål opnås ved hjælp af et koblingsarrangement som beskrevet i den indledende del af krav 1, og hvor mindst en af nævnte nedre koblingsdele er forbundet med et træk af nævnte køretøj, og hvor der mellem den nævnte øvre koblingsdel og nævnte nedre koblingsdele er tilvejebragt et antal længdejusterbare forbindelsesstænger.This object is achieved by means of a clutch arrangement as described in the preamble of claim 1, wherein at least one of said lower clutch parts is associated with a feature of said vehicle and where between said upper clutch part and said lower clutch part is provided. a number of length adjustable connecting rods.
30 Kort beskrivelse af opfindelsenBrief Description of the Invention
For at øge trykket på redskabet, således at redskabets tryk er redskabets egenvægt plus det tiyk, der udøves af koblingsarrangementet, er en af nævnte nedre koblingsdele DK 176105 B1 3 forbundet med et træk af nævnte køretøj og der er imellem den nævnte øvre koblings-part og nævnte nedre koblingsdele tilvejebragt et antal længdejusterbare forbindelses-stænger.In order to increase the pressure on the implement such that the pressure of the implement is the weight of the implement plus the pressure exerted by the coupling arrangement, one of said lower coupling parts DK 176105 B1 3 is associated with a drag of said vehicle and there is between said upper coupling part and said lower coupling members provide a plurality of length adjustable connecting rods.
5 Ved at anbringe længdejusterbare forbindelsesstænger mellem trepunktsarrangementets øvre del på redskabet og en nedre del af flerpunktsarrangementet på køretøjet samt en forbindelse mellem trepunktsarrangementet og flerpunktsarrangementet med koblingsarme og en yderligere længdejusterbar forbindelsestang, opstår der et kraftparallelogram omfattende trepunktsarrangementet, flerpunktsarrangementet, for-10 bindelsesstængeme og koblingsarmene, hvor de længdejusterbare forbindelsesstænger er placeret diagonalt i kraftparallelogrammet. Ved at variere længden af disse diagonale længdejusterbare forbindelsesstænger kan man ændre kraftparailelogrammets form.By placing length-adjustable connecting rods between the upper part of the three-point arrangement on the implement and a lower part of the multi-point arrangement on the vehicle, and a connection between the three-point arrangement and the multi-point arrangement with coupling arms and a further length-adjustable connecting rod arrangement, a three-point connecting armogram, , where the length-adjustable connecting rods are located diagonally in the force parallel log. By varying the length of these diagonal length adjustable connecting rods, one can change the shape of the force paralogogram.
Ved at koble et redskab og et køretøj ved hjælp af det foreliggende koblingsarrange-15 ment, er koblingsarrangementet i udgangspositionen påmonteret køretøjet, og de længdejusterbare forbindelsesstænger er indstillet i en bestemt længde, så de tillader ubesværet kobling af redskabet samt løftning og sænkning af redskabet.By coupling a tool and a vehicle by means of the present coupling arrangement, the coupling arrangement in the starting position is mounted on the vehicle and the length-adjustable connecting rods are set at a certain length to allow effortless coupling of the implement as well as lifting and lowering of the implement.
Når redskabet sænkes ned til jorden for at behandle jordoverfladen, er det muligt, at 20 øge det nedadgående tryk på redskabet ved at forkorte den længdejusterbare forbindelsesstang mellem den nedre del af køretøjets flerpunktsarrangement og trepunktsarrangementets øvre koblingsdel.As the implement is lowered to the ground to treat the ground surface, it is possible to increase the downward pressure on the implement by shortening the length-adjustable connecting rod between the lower portion of the vehicle's multi-point arrangement and the three-point arrangement's upper coupling portion.
I en foretrukken udførelsesform for den foreliggende opfindelse kan koblingsarrange-25 mentet udføres med et trepunktsarrangement, som er tilvejebragt på redskabet, og hvor førnævnte trepunktsarrangement er en integreret del af redskabet, hvor der i trepunktsarrangementet er placeret mindst en øvre koblingsdel og mindst to nedre koblingsdele, og hvor flerpunktsarrangementet, som er tilvejebragt på køretøjet, omfatter fire koblingsdele, herunder en øvre koblingsdel og tre nedre koblingsdele, og hvor en af de 30 nedre koblingsdele er fastgjort til køretøjets træk, og hvor en længdejusterbar foibin-delsesstang i den ene ende er fastgjort til nævnte nedre koblingsdel, og i den anden ende er fastgjort til en af trepunktsarrangementets øvre koblingsdele, og hvor der mel- DK 176105 B1 4 lem flerpunktsarrangementets øvre koblingsdel og trepunktsarrangementets øvre koblingsdele er anbragt en længdejusterbar forbindelsesstang, for eksempel en topstang eller en hydraulisk cylinder.In a preferred embodiment of the present invention, the coupling arrangement can be performed with a three-point arrangement provided on the implement, wherein said three-point arrangement is an integral part of the implement, wherein at least one upper coupling part and at least two lower coupling parts are located in the three-point arrangement. and wherein the multi-point arrangement provided on the vehicle comprises four coupling members, including an upper coupling member and three lower coupling members, and wherein one of the lower coupling members is attached to the feature of the vehicle and wherein a length adjustable foil linking rod is at one end. affixed to said lower coupling part, and at the other end is attached to one of the upper coupling parts of the three-point arrangement, and where a longitudinally adjustable connecting rod is arranged between the upper coupling part of the multi-point arrangement and the upper coupling part of the three-point arrangement. cylinder there.
5 I en udførelsesform for den foreliggende opfindelse omfatter nævnte øvre koblingsdel et antal koblingsøjne, som anvendes til at koble nævnte længdejusterbare forbindelsesstænger. Dette medfører, at det ikke er nødvendigt at fastgøre de længdejusterbare forbindelsesstænger i samme koblingsøje. De kan også fastgøres lidt forskudt.In one embodiment of the present invention, said upper coupling member comprises a plurality of coupling eyes used to couple said length adjustable connecting rods. This means that it is not necessary to attach the length adjustable connecting rods in the same coupling eye. They can also be attached slightly offset.
10 I en foretrukken udførelsesform forventes det, at den længdejusterbare forbindelsesstang, som er placeret mellem en af flerpunktsarrangementets nedre koblingsdele og en af trepunktsarrangementets øvre koblingsdele, monteres i fuld længde. Derfor omfatter nævnte nedre koblingsdele et antal koblingsplader, der hver især er forsynet med et antal koblingsøjne, hvilket medfører, at længdejusterbare forbindelsesstænger i 15 forskellige længder kan monteres i et sæt koblingsplader.In a preferred embodiment, it is expected that the length-adjustable connecting rod located between one of the lower coupling parts of the multi-point arrangement and one of the upper coupling parts of the three-point arrangement is mounted in full length. Therefore, said lower coupling members comprise a plurality of coupling plates, each provided with a plurality of coupling eyes, which means that length-adjustable connecting rods of 15 different lengths can be mounted in a set of coupling plates.
Hvis der anvendes flere længdejusterbare forbindelsesstænger mellem den nedre koblingsdel og den øvre koblingsdel, er den nedre koblingsdel udformet med flere sæt koblingsplader, således at hver længdejusterbar foibindelsesstang er forbundet med et 20 sæt koblingsplader. Disse koblingsplader er således placeret med en hvis afstand fra hinanden, således at der er plads mellem de længdejusterbare forbindelsesstænger.If multiple length adjustable connecting rods are used between the lower coupling part and the upper coupling part, the lower coupling part is formed with several sets of coupling plates, so that each length adjustable foil connecting rod is connected to a 20 set of coupling plates. Thus, these coupling plates are spaced apart, so that there is space between the length-adjustable connecting rods.
Dette medfører endvidere, at det er muligt at anvende køretøjets kraftudtag, da kraftovergang kan føres ud mellem de to længdejusterbare forbindelsesstænger. Derved kan koblingsarrangementet ifølge den foreliggende opfindelse endvidere anvendes til 25 redskaber, der har behov for kraftoverføring fra køretøjet.This also means that it is possible to use the vehicle's power take-off, since power transitions can be carried out between the two length-adjustable connecting rods. Furthermore, the coupling arrangement of the present invention can be used for 25 tools in need of power transmission from the vehicle.
Den nedre centralt placerede koblingsdel er typisk placeret i køretøjets træk, men kan alternativt være udformet, således at nævnte nedre koblingsdele er forbundet med en tværstang, der forbinder nævnte nedre koblingsdele, og således at der mellem den 30 nævnte øvre koblingsdel og nævnte nedre koblingsdele er tilvejebragt et antal længde-justerbare forbindelsesstænger.The lower centrally located clutch member is typically located in the vehicle feature, but may alternatively be formed such that said lower clutch member is connected to a transverse bar connecting said lower clutch member and so that there is between said upper clutch member and said lower clutch member. provided a number of length-adjustable connecting rods.
DK 176105 B1 5DK 176105 B1 5
Typisk vil den længdejusterbare forbindelsesstang mellem trepunktsarrangementets øvre del og flerpunktsarrangementets øvre del være en topstang, som bliver indstillet en gang for alle, når koblingsarrangementet monteres på køretøjet. Derudover kan den anden længdejusterbare forbindelsesstang mellem den nedre del af køretøjets fler-5 punktsarrangement og den øvre del af redskabets trepunktsarrangement også være en topstang.Typically, the length-adjustable connecting rod between the upper part of the three-point arrangement and the upper part of the multi-point arrangement will be a top rod, which is set once and for all when the coupling arrangement is mounted on the vehicle. In addition, the second length-adjustable connecting rod between the lower portion of the vehicle's multi-point arrangement and the upper portion of the three-point arrangement of the implement may also be a top rod.
Topstangen er enten mekanisk, hydraulisk eller pneumatisk drevet, således at den kan justeres. Således skal: 10 - en mekanisk drevet topstang drejes, hver gang der tilføres ekstra nedadgående kraft på redskabet, - en hydraulisk eller pneumatisk drevet topstang, kan aktiveres, så længden enten øges eller reduceres.The top bar is either mechanically, hydraulically or pneumatically driven so that it can be adjusted. Thus: 10 - a mechanically driven top bar must be turned every time additional downward force is applied to the implement, - a hydraulic or pneumatically driven top bar can be activated so that the length is either increased or reduced.
15 Alternativt kan en cylinder benyttes som længdejusterbar forbindelsesstang mellem den nedre koblingsdel på køretøjets flerpunktsarrangement og den øvre del af redskabets trepunktsarrangement.Alternatively, a cylinder may be used as a length adjustable connecting rod between the lower clutch portion of the vehicle's multi-point arrangement and the upper portion of the three-point arrangement of the implement.
Cylinderen kan være pneumatisk, hydraulisk eller elektrisk drevet, således at den kan 20 aktiveres inde fra køretøjet, når der ønskes en øget nedadgående kraft på redskabet.The cylinder may be pneumatically, hydraulically or electrically driven so that it can be actuated from within the vehicle when an increased downward force is desired on the implement.
Ved at overføre en nedadgående kraft fra køretøjet via en længdejusterbar forbindelsesstang reduceres trykket på køretøjets bagerste hjulaksel. Dette medfører, at køretøjet ikke skal have monteret den samme mængde frontvægt for at opveje kobling til et 25 redskab.By transmitting a downward force from the vehicle via a length-adjustable connecting rod, the pressure on the rear wheel axle of the vehicle is reduced. This means that the vehicle does not have to have the same amount of front weight fitted to offset clutch to a 25 implement.
Ifølge opfindelsen bliver det ved brug af et koblingsarrangement nemt for det efterfølgende redskab at holde en konstant jordbearbejdningsdybde, da køretøjets koblingsarme bærer/holder redskabet i den ønskede dybde, hvorefter trykket kan øges ved 30 hjælp af koblingens cylinder.According to the invention, by using a coupling arrangement, it becomes easy for the subsequent implement to maintain a constant tillage depth, since the coupling arms of the vehicle carry / hold the implement to the desired depth, after which the pressure can be increased by means of the coupling cylinder.
DK 176105 B1 6DK 176105 B1 6
Ved arbejde med tunge redskaber kan den længdejusterbare forbindelsestang mellem køretøjets træk og topdelen af redskabets trepunktsarrangement endvidere anvendes som hjælp til at løfte det tunge redskab.Furthermore, when working with heavy implements, the length-adjustable connecting rod between the vehicle's pull and the top of the three-point arrangement of the implement can be used to help lift the heavy implement.
5 Arrangementet er beskrevet anvendt til kobling mellem redskab og køretøj, men opfindelsen kan endvidere anvendes til at koble for eksempel to redskaber.The arrangement is described used for coupling between gear and vehicle, but the invention can also be used for coupling, for example, two gear.

At the lower end, the two longitudinally adjustable connecting rods 13a are attached to a coupling part 14 "which in turn is attached to the feature 16 of the vehicle in the same manner as the coupling part 14. The coupling part 14" comprises a plurality of coupling plates 32, each equipped with two rows of coupling eyes 15 for securing the length adjustable connecting rods 13a.
5 Et sådant koblingsarrangement 100 med de to længdejusterbare forbindelsesstænger 13a muliggør kraftoverførsel fra køretøjet (ikke vist) til et redskab (ikke vist). Desuden vil et sådant koblingsarrangement 100 kunne anvendes i forbindelse med et redskab uden en (A-ramme).Such a clutch arrangement 100 with the two length-adjustable connecting rods 13a enables power transmission from the vehicle (not shown) to a tool (not shown). Furthermore, such a coupling arrangement 100 could be used in connection with a tool without an (A-frame).
10 Fig. 4 viser et koblingsarrangement 1, hvor trepunktsarrangementet 2 er en integreret del af et redskab 40, som er vist som et skrabeblad.FIG. 4 shows a coupling arrangement 1, wherein the three-point arrangement 2 is an integral part of a tool 40 shown as a scraper blade.
I skrabebladet 40 er der anbragt en lynkobling 41 (A-ramme). Det vil sige, at koblingsarrangementet 1 hurtigt kan tilkobles skrabebladet 40 via trepunktsrammen 4.A quick-release coupling 41 (A-frame) is arranged in the scraper blade 40. That is, the coupling arrangement 1 can be quickly connected to the scraper blade 40 via the three-point frame 4.
15 I fig. 5 a og 5b vises, hvorledes en sammentrækning af den justerbare forbindelsesstang 13a medfører, at skrabebladet 40 trykkes ned mod jorden 50, hvorved det nedadgående tryk fra skrabebladet 40 øges.In FIG. Figures 5a and 5b show how a contraction of the adjustable connecting rod 13a causes the scraper blade 40 to be pressed against the ground 50, thereby increasing the downward pressure from the scraper blade 40.
20 I fig. 6a vises, hvorledes et koblingsarrangement 1 er anbragt på en tromle 60 ved hjælp af et trepunktsarrangement 2 og en lynkobling 41.In FIG. 6a shows how a coupling arrangement 1 is arranged on a drum 60 by means of a three-point arrangement 2 and a quick coupling 41.
I fig. 6b er vist en alternativ udførelsesform for opfindelsen, hvor koblingsarrangementet 1 er anbragt i forbindelse med en ramme 61 af en tromle 60. Trækstangen 63 25 på tromlen 60 anvendes til at koble et efterfølgende bugserredskab (ikke vist). På rammen 61 er monteret en lynkobling 41 (A-ramme). Det vil sige at, en tromle 60 hurtigt kan tilkobles koblingen 1 via trepunktsrammen 4.In FIG. 6b is shown an alternative embodiment of the invention, in which the coupling arrangement 1 is arranged in connection with a frame 61 of a drum 60. The drawbar 63 25 of the drum 60 is used to couple a subsequent towing tool (not shown). On the frame 61 is mounted a quick-release coupling 41 (A-frame). That is, a drum 60 can be quickly connected to the coupling 1 via the three-point frame 4.
Cylinderen 13a mellem koblingsarrangementet 1 og trepunktsarrangement 2 og fler-30 punktsarrangement 3 anvendes til at øge den nedadgående kraft på tromlen 60. Dette opnås ved at forkorte cylinderen 13a, hvorved en del af køretøjets (ikke vist) vægt overføres til tromlen 60.The cylinder 13a between the coupling arrangement 1 and three-point arrangement 2 and multi-point arrangement 3 is used to increase the downward force on the drum 60. This is achieved by shortening the cylinder 13a, whereby part of the weight of the vehicle (not shown) is transferred to the drum 60.
DK 176105 B1 9 På grund af tromlens 60 cylinderarrangement 62 kan der fra traktoren overføres en nedadgående kraft på tromlen, mens trækstangen 63 til det tilkoblede bugserredskab (ikke vist) holdes i en konstant position, således at en forøgelse af tromlens 60 tryk 5 ikke medfører en ændring af det tilkoblede bugserredskabs (ikke vist) forudbestemte jorddybde.Due to the cylinder arrangement 62 of the drum 60, a downward force can be transferred from the tractor to the drum, while the drawbar 63 of the coupled tow tool (not shown) is held in a constant position so that an increase in the pressure 5 of the drum 60 does not result a change in the predetermined soil depth of the coupled implement (not shown).
