Opfindelsen angår en tromle til agerbrug, hvor tromlelegemet er roterbart lejret ved sine ender i trom-lebærearme, som er fastgjort til en tromlebærebom, der i tromlens brugsstilling befinder sig over tromlelegemet 5 og forløber parallelt med tromlens akse.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a field drum, wherein the drum body is rotatably mounted at its ends in drum support arms, which is attached to a drum carrier boom which is in the position of use of the drum body 5 and runs parallel to the axis of the drum.
En sådan tromle kendes eksempelvis fra dansk mønsteranmeldelse MA 0581 1987, offentliggjort i Dansk Mønstertidende den 5. maj 1989. Denne tromletype har 10 pga. dens effektivitet og kompakte konstruktion fundet endog overordentlig udbredt anvendelse, men på trods af sine indlysende dyder har kontruktionen også sine begrænsninger. Hvor jorden før tromling udviser mange store jordknolde, som vil hindre korrekt tromling af 15 jorden, må der før tromlingen anvendes et andet landbrugsredskab, en såkaldt agerslæber, der er en stiv bjælke typisk forsynet med korte tænder anbragt med stort mellemrum og som slæbes hen over jorden til jævning af overjorden. Først efter at agerslæberen har 20 været marken igennem, kan en tromle som den i mønsteret viste anvendes til tromling af marken. Dette har hidtil betydet, at landmanden må gennemkøre marken to gange med hver sit arbejdsredskab for at opnå et tilfredsstillende tromlingsresultat.Such a drum is known, for example, from Danish Pattern Review MA 0581 1987, published in the Danish Pattern Journal on May 5, 1989. This drum type has found even widespread use due to its efficiency and compact construction, but despite its obvious virtues, limitations. Where the soil before drumming exhibits many large soil tubers that will prevent proper drumming of the soil, a different agricultural implement, a so-called field dredger, which is a rigid beam typically provided with short teeth placed at large intervals and which is dragged across, must be used before druming. the ground for leveling the upper ground. Only after the tiller has been through the field can a drum like the one shown in the pattern be used for druming the field. So far, this has meant that the farmer has to traverse the field twice with his or her own tools to obtain a satisfactory drum result.

Fra europæisk patentpublikation nr. 0266 276 kendes endvidere et større og mere kompliceret landbrugsredskab, der ud over udstyr til tromling omfatter et forud-løbende nivelleringsapparat, således at en tilfredsstil-30 lende tromling kan opnås. Dette nivelleringsapparat er stationært anbragt foran tromlerne og er fastgjort vinkelret på trækstangen samt styres og holdes på plads af to trykmediumcylindre. En ulempe herved er, at den vægtandel, som skal overføres fra tromlerne til nivelle-35 ringsorganet overføres via trækstangen,, dvs. centralt for landbrugsredskabet, og denne kraft skal optages af 2Furthermore, European Patent Publication No. 0266 276 discloses a larger and more complicated agricultural implement which, in addition to drum equipment, comprises a pre-leveling apparatus so that a satisfactory drum can be obtained. This leveling apparatus is stationary in front of the drums and is mounted perpendicular to the drawbar and is controlled and held in place by two pressure medium cylinders. A disadvantage of this is that the weight fraction to be transferred from the drums to the leveling means is transmitted via the drawbar, ie. central to the agricultural implement and this force must be absorbed by 2

traekstangens sammsnkoblingstap til landbrugsredskabet.drawbar linkage loss to the agricultural implement.
Dette sætter en grænse for nivelleringsorganets tryk-kraft, således at dette ikke kan få tilstrækkelig kraft til at blive ført ned under jordoverfladen under land-, 5 brugsredskabets arbejde. Tilkoblingen til trækstangen bevirker desuden, at nivelléringsapparatet dels bliver ustabilt ved enderne, dels at det har tendens til at vippe sideværts omkring trækstangen.This limits the leveling force of the leveling means so that it cannot get enough force to be brought down below the ground surface during the work of the implement. The connection to the drawbar further causes the leveling device to become partly unstable at the ends and partly to tend to tilt laterally around the drawbar.
10 Det er formålet med opfindelsen at angive en tromle af førstnævnte konstruktion med en agerslæber og samtidig undgå ulempen ved den anden konstruktion med nivelleringsapparat, dvs. med bibevarelse af førstnævnte konstruktions kompakte egenskaber og med en større og 15 mere direkte vægt på agerslæberen til at holde denne nedtrykket i jorden.SUMMARY OF THE INVENTION It is an object of the invention to provide a drum of the former construction with a sharpener and at the same time avoid the disadvantage of the second construction with leveling apparatus, i.e. with the retention of the compact properties of the former construction and with a greater and more direct emphasis on the tiller to keep this depression in the ground.
Dette opnås ifølge opfindelsen ved, at der i brugsstillingen foran tromlen er en agerslæber fastgjort til 20 tromlebærebommen over bærearme, der strækker sig fra bommen foran tromlelegemet ned mod jorden, og agerslæberen er i længdeudstrækningen svingbart hængslet til armenes yderende, idet agerslæberen er beliggende mellem armene og tromlelegemet, og efter tromlen kan der evt.This is achieved according to the invention in that in the position of use in front of the drum there is an axle trailer attached to the drum carrier boom over support arms extending from the boom in front of the drum body down to the ground, and the axle trailer is pivotally hinged to the outside of the arms, the axle lug being located between the arms. and the drum body, and after the drum, any

Desuden vil tromlelegemets vægt på en meget direkte måde via de korte arme holde agerslæberen i jor-30 den. I ekstreme situationer hvor agerslæberen vil løbe oven på jorden, overføres hele tromlelegemets vægt på agerslæberen. Agerslæberens stilling i forhold til jorden kan desuden reguleres ved drejning i hængslerne med en eller flere hydraulikcylindre forbundet til agerslæ-35 beren og bærebommen evt. et stykke oppe på bærearmene.In addition, a harrow is also connected to the carrier boom. In this embodiment, the drum retains its compact shape, since the roller can be brought close to the drum body. In addition, the weight of the drum body in a very direct manner via the short arms will keep the axle in the ground. In extreme situations where the ager will run on the ground, the entire weight of the drum body is transferred to the ager. The position of the axle trailer with respect to the ground can also be controlled by rotation of the hinges with one or more hydraulic cylinders connected to the axle trailer and the carrier boom, if applicable. a piece up on the support arms.

Hvor tromlen består af flere i kørestilling sammenfoldelige sektioner, hindrer agerslæberen ikke dette netop på grund af den kompakte sammenbygning.Where the drum consists of several sections foldable in driving position, the auger does not prevent this precisely because of the compact assembly.

Opfindelsen vil i det følgende blive nærmere forklaret i forbindelse med to udføreIsesformer og under henvisning til tegningen, hvor 10 fig. 1 viser en tromle monteret med agerslæber, og fig. 2 viser en tromle monteret med både agerslæber og harve.The invention will be further explained in the following in connection with two embodiments and with reference to the drawing, in which: FIG. 1 shows a drum mounted with shaft grinders, and fig. Figure 2 shows a drum mounted with both sharpener and harrow.
15 I fig. 1 er stiplet vist en tromle 1, der er roter- bart lejret ved sine ender 2 i tromlebærearme 3, der ligeledes er stiplet vist. Tromlebærearmene 3 er stift fastgjort til en ikke vist tromlebærebom af rektangulært eller kvadratisk tværsnit. Tromlebærebommens placering 20 er antydet ved 4. Tromlebærebommen befinder sig i tromlens 1 brugsstilling over tromlen og forløber parallelt med tromlens akse 5. Tromlebærebommen med tromle 1 kan trækkes, eksempelvis efter en traktor, og tromlebærebommen 4 udgør en del af landbrugsredskabets bærende kon-25 struktion i form af et stativ med koblingsorganer til traktoren og eventuelt med kørehjul til brug, når landbrugsredskabet transporteres ad offentlig vej. Ud over tromlebærebommen til nærværende tromle 1 kan der i landbrugsredskabet være andre tromlebærebomme for andre 30 tromler, og disse bærebomme kan eventuelt være ind- og udsvingelige fra en hvilestilling. Hver af disse tromlebærebomme kan bære to eller flere fastgørelsesorganer 6A, 6B. I fig. 1 er fastgørelsesorganet 6A forsynet med midler 7 til stift at fastgøre fastgørelsesorganet 6A på 35 tromlebærebommen 4 i en stilling ragende vinkelret ud fra bommen til den side heraf, som vender i tromlens l 4In FIG. 1, a drum 1 is rotatably shown rotatably mounted at its ends 2 in drum support arms 3 which are also dotted. The drum support arms 3 are rigidly attached to a rectangular or square cross-section drum carrier not shown. The position of the drum carrier boom 20 is indicated by 4. The drum carrier boom is in the position of use of the drum 1 over the drum and runs parallel to the axis of the drum 5. The drum carrier boom with drum 1 can be pulled, for example after a tractor, and the drum carrier boom 4 forms part of the agricultural implement carrying tool 25. in the form of a rack with coupling means for the tractor and possibly with drive wheels for use when transporting the agricultural equipment by public road. In addition to the drum carrier boom for the present drum 1, there may be other drum carrier booms for other 30 drums in the agricultural implement, and these carrier booms may be retractable and pivotal from a rest position. Each of these drum carrier bars can carry two or more fasteners 6A, 6B. In FIG. 1, the fastener 6A is provided with means 7 for rigidly fastening the fastener 6A to the drum carrier boom 4 in a position extending perpendicularly from the boom to the side thereof which faces in the drum 1 4

kørselsretning 16, dvs. mod venstre på tegningen. Ud over fastgørelsesmidlerne 7 har fastgørelsesorganet 6A en til fastgørelsesmidlerne fastgjort bærearm 8, ved hvis nederste ende en såkaldt agerslæber 9 er svingbart 5 i et lodret plan hængslet ved 10. Agerslæberen 9 er endvidere ved 11 hængslet forbundet med enden af en trykmediumcylinder 12, hvis modsatte ende ved 14 er hængslet forbundet med bærearmens 8 øverste ende. Derved udnyttes tromlebærebommen 4 til også at bære en agerslæ-10 ber via to eller flere fastgørelsesorganer 6A anbragt med visse mellemrum langs bommen 4.direction of travel 16, i.e. to the left of the drawing. In addition to the fastening means 7, the fastening means 6A has a supporting arm 8 attached to the fastening means, at the lower end of which is a so-called spreader 9 is pivotally 5 hinged at a vertical plane. end at 14, the hinge is connected to the upper end of the support arm 8. Thereby, the drum carrier boom 4 is utilized to also carry an actuator 10 via two or more fasteners 6A arranged at certain intervals along the boom 4.
I fig. 2 ses bommen 4 anvendt til både at bære mindst et par fastgørelsesorganer 6A og mindst et par 15 fastgørelsesorganer 6B, således at landbrugsredskabet, der oprindeligt blot var en tromle, hurtigt og let kan suppleres med en agerslæber og en harve 15. Landbrugsredskabets bærende konstruktoin behøver til disse operationer ikke at blive suppleret med ekstra længde i kør-20 selsretningen, da de påsatte fastgørelsesorganer 6A, 6B dels anvender en allerede eksisterende tromlebærebom 4 og dels forløber herfra ned på den ene aller den modsatte side af tromlen 1 i allerede eksisterende, ikke udnyttede monteringsåbninger. Fastgørelsesorganerne 6A, 6b 25 af- og påmonteres let ved hjælp af fastgørelsesmidlets 7 ikke nærmere viste bolte og møtrikker, således at landmanden valgfrit kan køre med landbrugsredskabets oprindelige tromle 1 alene eller efter påmontering af den ene eller den anden type fastgørelsesorgan 6A, 6B med ager-30 slæber 9 og/eller med harve.In FIG. 2, the boom 4 is seen used to carry at least one pair of fasteners 6A and at least one pair of 15 fasteners 6B, so that the agricultural implement, which was originally just a drum, can be quickly and easily supplemented by a tiller and a harrow 15. for these operations not to be supplemented with extra length in the direction of travel, since the attached fasteners 6A, 6B use a preexisting drum carrier 4 and extend from one to the opposite side of the drum 1 in preexisting utilized mounting openings. The fasteners 6A, 6b 25 are easily removed and mounted by means of the bolts and nuts not shown in the fastener 7, so that the farmer can optionally drive with the original drum 1 of the agricultural implement alone or after mounting one or the other type of fastener 6A, 6B with axes -30 tugs 9 and / or harrow.
Ingen har tidligere udnyttet denne mulighed for udnyttelse af tromlebærebommen 4 til påmontering af ekstraudstyr til trods for, at tromler med overliggende 35 tromlebærebom har været kendt siden 1975. Dette skyldes muligvis, at man ikke hidtil har anset tromlebærebommenNo one has previously taken advantage of this possibility of utilizing the drum carrier 4 for attaching optional equipment even though drums with overlying 35 drum carrier booms have been known since 1975. This may be because the drum carrier boom has not been considered so far.

5 4 som værende tilstrækkelig solid til at bære yderligere redskaber end den sædvanlige tromle.5 4 as being sufficiently solid to carry additional tools than the usual drum.
På tegningen viser 16 tromlens 1 arbejdskørsesreg-5 ning. Fastgørelsesmidlerne 7 er indrettet således, at de drejningsstift kan fastspænde fastgørelsesorganet 6A og/eller 6B til tromlebærebommen 4.In the drawing, 16 of the drum 1 shows the working run count. The fasteners 7 are arranged so that the pivot pins can clamp the fastener 6A and / or 6B to the drum carrier bar 4.
Hvor fastgørelsesorganet 6A bærer en agerslæber 9, 10 opnås en yderligere fordel ifølge opfindelsen, nemlig at man med trykmediumcylinderen 12 kan regulere agerslæberens 9 nedtrykningsdybde i jorden og derved indirekte regulere tromlens 1 nedtrykning af jorden, hvorved man udnytter den ulempe, at tromlens 1 vægt undertiden er 15 for høj til de givne jordforhold til at presse agerslæberen 9 med siden i indbyrdes afstand anbragte tænder ned i jorden til løsnelse af denne i større dybde, end det ellers havde været muligt, hvis tromlen 1 ikke havde været for tung. Omvendt kan agers læberens tryk ned i 20 jorden mindskes til kun at knuse de over jorden liggende jordknolde i det tilfælde, hvor tromlens l fulde vægt behøves. Opfindelsen bevirker endvidere, at landmandens omkostninger til landbrugsredskaber kan mindskes, når agerslæber og harve eller andet udstyr kan fås som ek-25 stratilbehør til et basislandbrugsredskab i form af en tromle. Den korte indbygningslængde for landbrugsredskabet bevirker endvidere, at dette kan vendes på mindre radius med agerslæber påmonteret bommen 4, end hvis agerslæbere havde været anbragt i et separat indkøbt 30 landbrugsredskab med agerslæber indkoblet mellem traktorens trækorgan og tromlens trækorgan.Where the fastener 6A carries a shaft 9, 10, a further advantage of the invention is obtained, namely that with the pressure medium cylinder 12 the depth of depression of the shaft 9 can be controlled in the ground and thereby indirectly regulate the depression of the drum 1, thereby taking advantage of the disadvantage that the weight of the drum 1 is 15 too high for the given ground conditions to press the axle 9 with the laterally spaced teeth into the ground to release it at greater depth than would otherwise have been possible had the drum 1 not been too heavy. Conversely, the pressure of the agar lip down into the soil can be reduced to crushing only the earthen tubers in the case where the full weight of the drum 1 is needed. The invention further provides that the farmer's cost of agricultural implements can be reduced when farms and harrows or other equipment can be obtained as an accessory to a basic agricultural implement in the form of a drum. Furthermore, the short installation length of the agricultural implement means that this can be reversed on a smaller radius with arable loader mounted on the boom 4 than if arable loader had been placed in a separately purchased agricultural implement with arable coupler coupled between the tractor's pulling member and the drum's pulling member.
