Den foreliggende opfindelse angår en landbrugsmaskine til drift fra kraftudtaget på en traktor og er af den i indledningen til krav 1 angivne art.The present invention relates to an agricultural machine for operation from the power take-off on a tractor and is of the kind specified in the preamble of claim 1.
Omdrejningshastighederne for kraftudtagsakslerne på landbrugstraktorer 5 er normalt 540 eller 1000 omdrejninger per minut.The speed of rotation of the PTO shafts on agricultural tractors 5 is usually 540 or 1000 rpm.
Talrige traktorer i brug har kraftudtag med enten den ene eller den anden af de nævnte hastigheder.Numerous tractors in use have power take-offs at either speed.
Det er allerede foreslået at udføre traktorerne med kraftudtag med begge hastigheder.It has already been proposed to power the tractors with both speeds.
10 Kraftudtagene har forskellig form efter som det drejer sig om 540 eller 1000 omdr./min. Som regel vil der være to former: en notaksel med 3,5 cm diameter og 6 noter ved kraftudtag med 540 omdr./min. og en notaksel med 3,5 crndSanater og 21 noter ved kraftudtag med 1000 15 omdr./min.10 The power take-offs have different shapes as they are 540 or 1000 rpm. As a rule, there will be two forms: a 3.5 cm diameter shaft and 6 notes at 540 rpm power take-off. and a note shaft with 3.5 crndSanates and 21 notes at power take-off with 1000 15 rpm.
I almindelighed skal landbrugsmaskinerne drives med en bestemt hastighed, idet deres indre organer er indrettet til enten den ene eller den anden af de nævnte hastigheder.Generally, the agricultural machines must be operated at a particular speed, with their internal means arranged at either one or the other of said speeds.
Det påhviler derfor brugeren at indrette hver maskine han køber 20 efter den forhåndenværende traktor. Maskinen må derfor påmonteres et passende gear.It is therefore the responsibility of the user to design each machine he purchases 20 according to the existing tractor. The machine must therefore be fitted with a suitable gear.
For konstruktøren er det umuligt at vide det antal gearkasser og transmissionsaksler til den ene eller anden hastighed, som skal bruges, og hver maskine må ekspederes med forskellig gearkasse og transmissionsaksel.For the designer, it is impossible to know the number of gearboxes and transmission shafts at either speed to be used, and each machine must be dispensed with different gearboxes and transmission shafts.
25 For fabriken betyder det, at den er nødt til at holde de forskellige gearkasser og aksler på lager.25 For the factory, this means that it has to keep the various gearboxes and shafts in stock.
En landmand med en traktor med 540 omdr./min. og en anden traktor med 1000 omdr./min. kan ikke spænde dem for enhver maskine. Er den traktor, der er egnet til maskinen, optaget af andet arbejde, kan den anden traktor 30 ikke spændes for. Dette er især en ulempe under høsten, hvor meteorologiske forhold og produkternes moden hed skal udnyttes hurtigt.A farmer with a tractor with 540 rpm. and another 1000 rpm tractor. cannot clamp them on any machine. If the tractor suitable for the machine is occupied by other work, the second tractor 30 cannot be tensioned. This is especially a disadvantage during the harvest, where meteorological conditions and the maturity of the products must be exploited quickly.
Man kunne tænke sig at anvende en gearkasse med to hastigheder, hvor man kunne vælge hastighed efter den ene eller anden art traktor, men dette har den ulempe, at det ville være nødvendigt med to trans-35 missionsaksler med kardanled for at kunne foretage tilpasningen til den ene eller den anden form for kraftudtag.You might want to use a two-speed gearbox where you can select speed according to one or the other type of tractor, but this has the disadvantage that two rear axle transmission shafts would be required to make the adjustment to one or the other type of power take-off.
Den samme ulempe gælder traktorer, ved hvilke man kan vælge 540 eller 1000 omdr./min.The same disadvantage applies to tractors where 540 or 1000 rpm can be selected.
Desuden har den nævnte gearkasse den ulempe, at den er relativt dyr 40 på grund af omstillingsmekanismen.In addition, the said gearbox has the disadvantage of being relatively expensive 40 due to the switching mechanism.

I det amerikanske patentskrift nr. 3 001 409 er beskrevet en gearkasse, der kan skrues fast over kraftudtaget, og som har en aksel med 540 omdr./min. og 6 noter samt en aksel med 1000 omdr./min. og 21 noter.U.S. Patent No. 3,001,409 discloses a gearbox that can be screwed over the power take-off and has a shaft with 540 rpm. and 6 notes as well as a shaft with 1000 rpm. and 21 notes.
Herved løses nogle af problemerne, nemlig for fabriken og konstruktøren 5 samt lagerproblemer hos forhandlerne af sådanne maskiner, men ikke brugerens problemer med tilpasning.This solves some of the problems, namely for the factory and the manufacturer 5, as well as storage problems at the dealers of such machines, but not the user's problems with adaptation.
Hvis brugeren har to traktorer, den ene med 540 omdr./min. og den anden med 1000 omdr./min., er han nødt til at skifte gearkassen fra den ene til den anden eller anskaffe to gearkasser.If the user has two tractors, one with 540 rpm. and the other at 1000 rpm, he has to switch the gearbox from one to the other or acquire two gearboxes.
10 Det kan også ske, at der skal anvendes to maskiner, der begge kræver 540 omdr./min. Brugeren må da på den traktor, der har 1000 omdr./min. montere en sådan gearkasse, der kan omsætte disse omdrejninger til 540 omdr./min. Hvis der kort tid efter forekommer to maskiner, der er indrettet til at drives ved 1000 omdr./min., må brugeren flytte gearkassen, som er 15 anbragt på traktoren med 1000 omdr./min., til anbringelse på traktoren med 540 omdr./min.10 You may also need to use two machines, both of which require 540 rpm. The user must then use the tractor which has 1000 rpm. mount such a gearbox that can translate these revolutions to 540 rpm. If shortly after, two machines arranged to operate at 1000 rpm appear, the user must move the gearbox, which is 15 located on the 1000 rpm tractor, to be placed on the tractor with 540 rpm. /mine.
Der findes særlig kraftige traktorer med kraftudtag med 1000 omdr./min. og to aksler med 4,5 cm. diameter og henholdsvis 6 og 20 noter.There are particularly powerful tractors with power take-offs with 1000 rpm. and two 4.5 cm shafts. diameter and 6 and 20 notes, respectively.
Der findes også landbrugsmaskiner, der er indrettet til at drives af 20 sådanne traktorer, men tilpasningsproblemerne er de samme som ved de allerede nævnte maskiner.There are also agricultural machines that are designed to be driven by 20 such tractors, but the adjustment problems are the same as with the machines already mentioned.
Fra FR-A-2 399 201 kendes et transmissionssystem til en landbrugsmaskine, hvor transmissionssystemet har to indgangsaksler med fortandinger, og hvor disse fortandinger direkte samvirker med et tandhjul. Herved opnås 25 med en omstillingsmekanisme to forskellige hastigheder i maskinens høst^'i' værktøjer, der kan være hensigtsmæssige ved forskellige afgrøder. Dette system er dog ikke velegnet til tilpasning af en landbrugsmaskine til forskellige former for eri traktors kraftudtag.From FR-A-2 399 201, a transmission system is known for an agricultural machine, in which the transmission system has two input shafts with teeth and where these teeth directly interact with a gear. Hereby, with a switching mechanism, two different speeds are obtained in the harvesting of the machine in tools that may be convenient for different crops. However, this system is not suitable for adapting an agricultural machine to various types of erector tractors.
Det er den foreliggende opfindelses formål at anvise en landbrugsmaskine 30 til drift fra kraftudtaget på en traktor, ligegyldig af hvilken art, uden at en særlig tilpasning hos brugeren er nødvendig.SUMMARY OF THE INVENTION It is an object of the present invention to provide an agricultural machine 30 for operation from the power take-off on a tractor, of any kind, without the need for a special adjustment by the user.
Landbrugsmaskinen ifølge opfindelsen er ejendommelig ved det i den kendetegnende del af krav 1 anførte. Herved opnås, at de ovenfor nævnte problemer løses, idet maskinen kan forbindes til en hvilken som helst 35 traktor uden speciel tilpasning.The agricultural machine according to the invention is characterized by the characterizing part of claim 1. This achieves that the above-mentioned problems are solved as the machine can be connected to any tractor without special adaptation.

Ifølge opfindelsen kan den indgangsaksel, som er beregnet på 1000 omdr./min., med fordel have en diameter på 3,5 cm og 6 noter, og den indgangsaksel, der er beregnet på 540 omdr./min., have en diameter på 3,5 cm og 21 noter.According to the invention, the input shaft calculated at 1000 rpm may advantageously have a diameter of 3.5 cm and 6 notes and the input shaft calculated at 540 rpm may have a diameter of 3.5 cm and 21 notes.
5 Herved opnås ved kombination med akslen med kardanleddene, hvori den ene yderende har en boring med 6 noter og den anden yderende en boring med 21 noter, at den her omhandlede maskine kan forbindes til en hvilken .som helst af de sædvanlige traktorer.Hereby, in combination with the shaft with the universal joints, wherein one end has a 6-groove bore and the other outer a 21-groove bore, this machine can be connected to any of the usual tractors.
Skal maskinen forbindes til en traktor med 1000 omdr./min., anbringes 10 den ende af akslen, der har 21 noter, på kraftudtaget, og den anden ende af akslen ned 6 noter på maskinens indgangsaksel, der har 6 noter svarende til 1000 omdr./min.If the machine is to be connected to a 1000 rpm tractor, 10 places the end of the shaft, which has 21 notes, on the power take-off, and the other end of the shaft down 6 notes on the input shaft of the machine, which has 6 notes corresponding to 1000 rpm. ./mine.
Skal samme maskine forbindes til en traktor med kraftudtag med 540 omdr./min,, er det tilstrækkeligt at vende den nævnte aksel, så at enden 15 med 6 noter anbringes på kraftudtaget, medens den anden ende af akslen anbringes på maskinens indgangsaksel med 21 noter for 540 omdr./min.If the same machine is to be connected to a tractor with a power take-off of 540 rpm, it is sufficient to turn the said shaft so that the end 15 with 6 notes is placed on the power take-off, while the other end of the shaft is placed on the input shaft of the machine with 21 notes. for 540 rpm.
Til landbrugsmaskiner, der kræver særlig kraftige traktorer, kan man løse tilpasningsproblemerne på fuldstændig tilsvarende måde.For agricultural machines requiring particularly powerful tractors, the matching problems can be solved in a completely similar way.
Ved opfindelsen opnås således, at alle problemer for fabrikanten 20 ved fremstilling af ny maskiner og lagerholdning af forbindelsesdele samt alle brugerens problemer forsvinder.The invention thus achieves that all problems for the manufacturer 20 in the manufacture of new machines and storage of connecting parts as well as all the problems of the user disappear.
Desuden opnås, at der ikke kræves noget særligt udstyr af værktøj til forbindelse af en maskine ifølge opfindelsen, sådan som det er tilfældet med anbringelsen af den ovenfor nævnte kendte gearkasse.Furthermore, no special equipment of tools is required for connecting a machine according to the invention, as is the case with the arrangement of the above-mentioned known gearbox.
25 Endelig opnås den fordel ved maskinen ifølge opfindelsen, at der ikke er nogen mulighed for fejltagelse ved fremstillingen af forbindelsen mellem traktor og maskine.Finally, the advantage of the machine according to the invention is that there is no possibility of error in the manufacture of the connection between the tractor and the machine.
Opfindelsen forklares i det følgende nærmere under henvisning til tegningen, hvor 30 fig. 1 skematisk og perspektivisk viser en del af en udførelsesform for en landbrugsmaskine ifølge opfindelsen set forfra og fig. 2 et snit gennem maskinens gearkasse samt den tilhørende kardanaksel.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail with reference to the accompanying drawings, in which 1 is a schematic and perspective view of a part of an embodiment of an agricultural machine according to the invention in front view; and FIG. 2 is a section through the gearbox of the machine and the associated PTO shaft.
I fig. 1 er skematisk og perspektivisk vist en del af en slåmaskine, 35 der med en vognstang 1 er beregnet til at trækkes efter en ikke vist traktor, forbundet til den med 2 betegnede del.In FIG. 1 is a schematic and perspective view of a part of a mower 35 which, with a trolley 1, is intended to be towed after a tractor not shown, connected to the part designated 2.
Den anden ende af stangen 1 er fastgjort til slåmaskinens chassis 4.The other end of the rod 1 is attached to the mower chassis 4.

En bom 5 og ikke viste dele er anbragt under en kappe 6, der foran har en skærm 7 til beskyttelse mod sten eller lignende genstande, der kan kastes fra roterende skiver 8, der er elliptiske og har to knive 9<. der kan dreje frit og beskyttes af skiverne 8, hvis der træffes en hindring.A boom 5 and parts not shown are placed under a sheath 6 which has a front 7 for protection against stones or similar objects which can be thrown from rotating discs 8 which are elliptical and have two blades 9 <. which can be freely rotated and protected by the washers 8 if an obstruction is encountered.
5 Knivene 9 holdes automatisk i arbejdsstilling af centrifugalkraften.5 The blades 9 are automatically held in the centrifugal force working position.
På den med 3 betegnede del af stangen 1 er svejset en understøtning 10 for en gearkasse 11, der har to indgangsaksler 12 og 13. I fig. 1 er akslen 12 fri, medens der til akslen 13 er forbundet en transmissionsaksel 14, hvoraf den yderste del 22 skal forbindes til traktoren.On the part 1 of the rod 1 indicated by 3 is welded a support 10 for a gearbox 11 having two input shafts 12 and 13. In FIG. 1, the shaft 12 is free, while a transmission shaft 14 is connected to the shaft 13, the outermost part 22 of which is to be connected to the tractor.
10 En anden kardanaksel 16 overfører bevægelsen fra gearkassen 11'til en mekanisme 17, der driver skiverne 8, der roterer med en hastighed af omkring 3000 og 1000 omdr./min.A second PTO shaft 16 transmits the movement from the gearbox 11 to a mechanism 17 driving the washers 8 which rotate at a speed of about 3000 and 1000 rpm.
Som det vil fremgå af fig. 2 danner akslen 12 en fælles aksel 19 med den med 18 betegnede udgangsaksel og er beregnet for et kraftudtag med 1000 15 omdr./min.As will be seen from FIG. 2, the shaft 12 forms a common shaft 19 with the output shaft designated 18, and is intended for a power take-off of 1000 15 rpm.
I mekanismen 17 er et omsætningsforhold på 1:3 tilstrækkeligt til skiverne 8, og til de øvrige ikke viste dele af slåmaskinen er et omsætningsforhold 1:1 tilstrækkeligt.In mechanism 17, a 1: 3 turnover ratio is sufficient for the washers 8, and for the other parts of the mower not shown, a 1: 1 turnover ratio is sufficient.
Til en mere langsom maskine kan akslen 13 være beregnet for 540 omdr./min. 20 og være i ét stykke med udgangsakslen.For a slower machine, shaft 13 may be designed for 540 rpm. 20 and be integral with the output shaft.
Der kan imidlertid også være to udgangsaksler, så at akslen 12 for 1000 omdr./min. er i ét stykke med den ene udgangsaksel og akslen 13 for 540 omdr./min. er i ét stykke med den anden udgangsaksel.However, there may also be two output shafts so that the shaft 12 for 1000 rpm. is integral with one output shaft and shaft 13 for 540 rpm. is in one piece with the other output shaft.
En sådan gearkasse er universel på den måde, at den anbragt på en 25 landbrugsmaskine, hvor værktøjerne roterer·meget hurtigt, har akslen 16 forbundet til den første udgangsaksel, og når den er anbragt på en maskine med langsomtgående værktøjer, har akslen 16 forbundet til den anden udgangsaksel. På denne måde kan forøgelsen af hastigheden i det første tilfælde og formindskelsen af hastigheden i det andet tilfælde 30 udføres på fordelagtig måde.Such a gearbox is universal in that it is mounted on an agricultural machine where the tools rotate very quickly, the shaft 16 is connected to the first output shaft, and when mounted on a machine with slow-moving tools, the shaft 16 is connected to the the second output shaft. In this way, the increase in velocity in the first case and the decrease in velocity in the second case 30 can be advantageously carried out.
I fig. 2 er vist et snit gennem maskinens gearkasse 11 med dens to indgangsaksler 12 og 13, der 'har henholdsvis 6 og 21 noter. I det med 15 betegnede kardanled findes en boring med 21 noter, medens der i det med 22 betegnede kardanled findes en boring med 6 noter.In FIG. 2 is a section through the gearbox 11 of the machine with its two input shafts 12 and 13 having 6 and 21 grooves respectively. A 15-bit bore is provided with a 21-groove bore, while a 22-groove bore has a 6-groove bore.
35 Når maskinen med akslen 14 forbindes til en traktor, hvor kraftudtaget har 1000 omdr./min. og 21 noter, er det kardanleddetl5, der forbindes hertil.35 When the machine with the shaft 14 is connected to a tractor where the PTO has 1000 rpm. and 21 notes, it is the cardinal joint associated therewith.
Når maskinen forbindes til en traktor med kraftudtag med 540 omdr./min. og 6 noter, er det tilstrækkeligt at vende akslen 14, så at boringen 21 sættes på udtaget og boringen 20 på akslen 13.When connecting the machine to a 540 rpm power tractor. and 6 notes, it is sufficient to turn the shaft 14 so that the bore 21 is put on the outlet and the bore 20 on the shaft 13.

Akslen 19 har en fortanding 23, så at der her dannes et tandhjul.The shaft 19 has a tooth 23 so that a cog is formed here.
Akslen 18 har hensigtsmæssigt 6 noter som akslen 12, men kan have et andet antal.The shaft 18 suitably has 6 notes like the shaft 12, but may have a different number.
På hver side af fortandingen 23 findes kuglelejer 24 og 25, så at 5 akslen 19 kan dreje i disse, fastholdt med clips 28 og 29 i boringer 26 og 27.On each side of the tooth 23 there are ball bearings 24 and 25, so that the shaft 19 can rotate in these, held by clips 28 and 29 in bores 26 and 27.
30 og 31 betegner akseltætninger for olie i kassen 11.30 and 31 denote shaft seals for oil in box 11.
32 betegner den ende af akslen 13, der er forsynet med 21 noter, og 33 er en mangenot på den, samvirkende med en indre mangenot 34 i et 10 tandhjul 35 til overførelse af bevægelsen.32 denotes the end of the shaft 13 provided with 21 notes, and 33 is a multi-note on it, cooperating with an inner multi-note 34 in a pinion 35 for transmitting the motion.
På hver side af tandhjulet 35 findes skiver 36 og 37, mod hvilke støtter sig de indre ringe af rullelejer 38 og 39, hvis ydre ringe støtter sig mod en skulder 40 i en boring 41 i kassen 11 og en skulder 42, der er udformet i en holder 43, som er anbragt i en boring 44 i kassen 11, 15 sikret med clips 45, så at akslen 13 ikke kan forskydes.On each side of the sprocket 35 are discs 36 and 37 against which the inner rings of roller bearings 38 and 39, the outer rings of which support against a shoulder 40 in a bore 41 in the box 11 and a shoulder 42 formed in a holder 43 disposed in a bore 44 in the box 11, 15 secured by clips 45 so that the shaft 13 cannot be displaced.
Anvendelsen af den dækselagtige holder 43 er nødvendig, da diameteren af boringen 44 skal være så stor, at der er plads til anbringelse af tandhjulet 35 i kassen 11. Tæthed opnås med pakninger 46 og 47. Omsætningsforholdet mellem tandhjulet 35 og fortandingen 23 kan hensigtsmæssigt 20 være 2:1.The use of the cover-like holder 43 is necessary, since the diameter of the bore 44 must be so large as to accommodate the gear 35 in the box 11. Density is obtained with gaskets 46 and 47. The ratio of the ratio of the gear wheel 35 to the tooth 23 can suitably be 20 be 2: 1.
Når maskinen er trukket af en traktor, hvis kraftudtag drejer 1000 omdr./min. er transmissionsakslen forbundet til indgangsakslen 12, og da denne aksel er i ét stykke med udgangsakslen 18, drejer denne også med 1000 omdr./min. Når maskinen er forbundet med en traktor, hvis kraftudtag 25 drejer 540 omdr./min, er transmissionsakslen 14 forbundet med indgangsakslen 13, og på grund af omsætningsforholdet 2:1 vil udgangsakslen 18 dreje med omtrent 1000 omdr./min.When the machine is pulled by a tractor whose PTO shaft turns 1000 rpm. For example, the transmission shaft is connected to the input shaft 12, and since this shaft is integral with the output shaft 18, it also rotates at 1000 rpm. When the machine is connected to a tractor whose PTO 25 rotates 540 rpm, the transmission shaft 14 is connected to the input shaft 13, and because of the 2: 1 turnover ratio, the output shaft 18 will rotate at approximately 1000 rpm.
For at udgangsakslen 18 skal få samme omdrejningsretning, uanset, at akslen 14 er forbundet enten til akslen 12 eller til akslen 13, er der 30 anbragt en mellemaksel 48 med et tandhjul 49, som overfører bevægelsen fra tandhjulet 35 til fortandingen 23. Tandhjulet 49 er i forbindelse med akslen 48 gennem en mangenot 50 på denne, indgribende i en tilsvarende indre : raangenot i tandhjulet 49, betegnet 51.In order for the output shaft 18 to have the same direction of rotation, regardless of whether the shaft 14 is connected either to the shaft 12 or to the shaft 13, an intermediate shaft 48 is provided with a sprocket 49 which transmits the movement from the sprocket 35 to the gear tooth 23. The sprocket 49 is in connection with the shaft 48 through a manifold 50 on it, engaging in a corresponding interior: the annular note in the sprocket 49, designated 51.
På hver side af tandhjulet 49 er anbragt skiver 52,53, mod hvilke 35 støtter sig de indre ringe i kuglelejer 54,55. Mellemakslen 48 er hindret i at forskydes af clips 58,59 i boringer 56,57. 60 og 61 betegner lukkepropper .Discs 52.53 are provided on each side of the gear 49, against which the inner rings of ball bearings 54.55 are supported. The intermediate shaft 48 is prevented from being displaced by clips 58.59 in bores 56.57. 60 and 61 denote closure plugs.
Der findes maskiner, hvor omdrejningsretningen er ligegyldig, og mellemakslen 48 kan da undværes og tandhjulet 35 gribe direkte ind i fortandingen 40 23.There are machines in which the direction of rotation does not matter, and the intermediate shaft 48 can then be dispensed with and the sprocket 35 directly engages the gear 40 23.

Maskinen kan også være udformet således, at akslen 18 kan undværes, idet tandhjulet 35 eller fortandingen 23 kan samvirke med et tandhjul i maskineriet.The machine can also be designed so that the shaft 18 can be avoided, the gear 35 or the tooth 23 being able to cooperate with a gear in the machinery.
Der findes som nævnt landbrugsmaskiner, som kræver en særlig kraftig 5 traktor.As mentioned, there are agricultural machines that require a particularly powerful 5 tractor.
Kraftudtagené på sådanne traktorer har som regel 1000 omdr./min. og der findes to aksler: notaksel med diameter4,5 cm (eller 1 3/4") og 6 noter og en notaksel med diameter 4,5 cm (eller (1 3/4") og 20 noter.The power take-off on such tractors is usually 1000 rpm. and there are two shafts: 4.5 cm diameter (or 1 3/4 "diameter) and 6 notes and a 4.5 cm diameter (or (1 3/4")) shaft and 20 notes.
