Description

i U 8341and U 8341

Opfindelsen angår en roehøster med en hovedramme, hvorpå der findes opgravningsorganer og skovlhjul, over hvilke roerne tilføres en transportør og over denne føres til renseruller, som har skrueformede skovl vindinger, og som hver drives i modsat cradre jningsretning af den eller de nærmeste af de andre renseruller, og hvor mindst én renserulle består af en transportdel og en afleveringsdel.The invention relates to a beet harvester with a main frame, on which there are excavating means and impellers, over which the beets are fed to a conveyor and over this are fed to cleaning rollers which have helical vane turns and which are each driven in the opposite direction of the nearest or the other cleaning rollers, and wherein at least one cleaning roller consists of a transport part and a delivery part.

Fra US-PS nr. 4.024.920 kendes en roehøster, som er forsynet med en hovedramme, med opgravningsorganer og skovlhjul, som tilfører de høstede roer til en kædetransportør, hvormed roerne så tilføres renseruller, der bærer skrueformede, på rense-rullerne roterbare skovlvindinger, og som består af en transportdel og en afleveringsdel. Afleveringsdelen af den første og tredje renserulle er udformet med en modløbende skrueskovl-vinding, medens den mellem den første og anden renserulle anbragte rense- eller skraberulle ikke har nogen skrueformet skovlvinding. Over enden af afleveringsdelen føres roerne til en rensetromle, hvilket kan medføre den ulempe, at rullernes lejer tilstoppes med jord og planterester.U.S. Pat. No. 4,024,920 discloses a beet harvester which is provided with a main frame, with excavating means and impellers, which feed the harvested beets to a chain conveyor, with which the beets are then supplied with cleaning rollers carrying helical vanes rotatable on the cleaning rollers. , and which consists of a transport part and a delivery part. The delivery part of the first and third cleaning rollers is formed with an opposite screw vane winding, while the cleaning or scraping roller arranged between the first and second cleaning roller has no helical vane winding. Above the end of the delivery part, the beets are led to a cleaning drum, which can lead to the disadvantage that the bearings of the rollers are clogged with soil and plant residues.

I modsætning hertil er formålet med den foreliggende opfindelse at udforme og anbringe renserullernes afleveringsdel, således at roerne afkastes fra siden af rullerne. Dette er ifølge opfindelsen opnået ved, at afleveringsdelen af den anden renserulle regnet fra opgravningsorganeme er indrettet til at blive drevet i en andre jningsretning modsat andre jningsretningen af renserul lens transportdel og i saimie andre jningsretning san de nærmeste renseruller. Ved denne udformning af afleveringsdelene og af naborenserullerne, son alle drives i samme andre jningsretning, kan roerne uden at passere over lejerne afgives til f.eks. en efterfølgende rensetromle. Hertil er det hensigtsmæssigt, at yderdiameteren af transportdelene på den første og anden renserulle er lige store, og at yderdiameteren af afleveringsdelen på den anden renserulle er mindre end den førstnævnte yderdiameter. Endvidere er det fordelagtigt, at den første del, dvs. transportdelen af den anden renserulle er udformet som et rør, hvori den ene ende 2 148341 af den anden del, dvs. afleveringsdelen, er drejeligt lejret, medens dens anden ende drives fra en af renserullerne, og at afleveringsdelen ved hjælp af to rullelejer er drejeligt lejret i transportdelens rør. Når i det mindste den anden renserulle er todelt, og transportdelen er udformet som et rør, er det uden videre muligt at optage afleveringsdelen drejeligt i røret og drive den i modsat omdrejningsretning af transportdelen. På denne måde får man for alle tre afleveringsdele af renserullerne samme omdrejningsretning. Ved at anvende mindst to rullelejer for den drejelige afleveringsdel sikres en god understøtning af afleveringsdelen i renserullens transportdel .In contrast, the object of the present invention is to design and arrange the delivery part of the cleaning rollers so that the beets are returned from the side of the rollers. This is achieved according to the invention in that the delivery part of the second cleaning roller calculated from the excavating means is arranged to be driven in a second opening direction opposite to the second opening direction of the transport part of the cleaning roller and in the same second opening direction as the nearest cleaning rollers. In this design of the delivery parts and of the adjacent cleaning rollers, which are all driven in the same other opening direction, the tubes can be delivered to e.g. a subsequent cleaning drum. For this purpose, it is expedient for the outer diameter of the transport parts on the first and second cleaning rollers to be equal and for the outer diameter of the delivery part on the second cleaning roll to be smaller than the first-mentioned outer diameter. Furthermore, it is advantageous that the first part, i.e. the transport part of the second cleaning roller is designed as a tube, in which one end of the other part, i.e. the delivery part, is rotatably mounted, while its other end is driven from one of the cleaning rollers, and that the delivery part is rotatably mounted in the pipe of the transport part by means of two roller bearings. When at least the second cleaning roller is divided into two parts and the transport part is designed as a pipe, it is readily possible to receive the delivery part rotatably in the pipe and drive it in the opposite direction of rotation of the transport part. In this way you get the same direction of rotation for all three delivery parts of the cleaning rollers. By using at least two roller bearings for the rotatable delivery part, a good support of the delivery part in the transport part of the cleaning roller is ensured.

Opfindelsen forklares nærmere i det følgende i forbindelse med en udførelsesform for roehøsteren ifølge opfindelsen.The invention is explained in more detail below in connection with an embodiment of the beet harvester according to the invention.

Neden under den forreste tværdrager 18, som er indstilleligt forbundet med tilkoblingsmekanismen 20, findes et antal opgravningsorganer 22, som hver består af et par grave- eller ryddehjul 24, som er drejeligt lejret på en vertikalt forløbende og med tværdrageren 18 forbundet stander 26. Bag ved hvert opgravningsorgan 22 findes et skovlhjul 28, som er anbragt mellem de øverste, bageste og i afstand fra hinanden liggende dele af gravehjulene 24 til optagelse af de løftede roer og til at lede dem bagud. Skovlhjulene 28 er lejret på en tværgående aksel 30 og kan sammen med deres opgravningsorganer 22 indstilles i en retning på tværs af roehøsterens 10 køreretning.Below the front cross member 18, which is adjustably connected to the coupling mechanism 20, there are a number of excavating means 22, each consisting of a pair of digging or clearing wheels 24, which are rotatably mounted on a vertically extending stand and connected to the cross member 18. at each excavating means 22 there is an impeller 28 which is arranged between the upper, rear and spaced apart parts of the digging wheels 24 for receiving the lifted beets and for guiding them rearwards. The impellers 28 are mounted on a transverse shaft 30 and, together with their excavating means 22, can be adjusted in a direction transverse to the direction of travel of the beet harvester 10.

Roerne ledes over skovlhjulet 28 til en kædetransportør 32, som strækker sig mellem hovedrammens 12 sidedele 34. Roerne bliver med kædetransportøren 32 transporteret bagud og ført til en anden transportør 36, som forløber på tværs af roe-høsteren 10. Den anden transportør 36 har samvirkende, modsat omløbende renseruller 38 og 40 samt 42 og 44. Hver rulle 38 til 44 er udformet med en cylindrisk kerne eller et rør, hvorpå der er anbragt skrueformet forløbende skovlvindinger 46, som er fastgjort på rørets yderside. Hver renserulle 38, 42 og 44 er anbragt centreret på aksler 48, 50, 52. Akslerne 48, 50 og 52 er ved enderne drejeligt lejrede i rullelejer. Akselen 76 for renserullen 40 har en del, som ikke strækker sig gennem renserullens rør. Renserullen 40's rør er ved enden drejeligt lejret på en del 54 ved hjælp af to rullelejer 56 og 60 (fig. 3). På lignende måde er dets modsat liggende ende 57 lejret i et tredje rulleleje. Renserullerne 38 til 44 i den anden transportør 36 samt roehøsteren 10's andre arbejds-værktøjer trækkes fra traktorens kraftudtagsaksel, som for simpelheds skyld ikke er vist på tegningen.The beets are guided over the impeller 28 to a chain conveyor 32 which extends between the side portions 34 of the main frame 12. The beets are transported backwards with the chain conveyor 32 and led to another conveyor 36 which extends across the beet harvester 10. The second conveyor 36 has cooperating , opposite circumferential cleaning rollers 38 and 40 and 42 and 44. Each roller 38 to 44 is formed with a cylindrical core or tube on which are arranged helically extending vane windings 46 which are attached to the outside of the tube. Each cleaning roller 38, 42 and 44 is arranged centered on shafts 48, 50, 52. The shafts 48, 50 and 52 are rotatably mounted at the ends in roller bearings. The shaft 76 of the cleaning roller 40 has a portion which does not extend through the tube of the cleaning roller. The tubes of the cleaning roller 40 are rotatably mounted at the end on a part 54 by means of two roller bearings 56 and 60 (Fig. 3). Similarly, its opposite end 57 is mounted in a third roller bearing. The cleaning rollers 38 to 44 in the second conveyor 36 as well as the other working tools of the beet harvester 10 are pulled from the tractor shaft of the tractor, which for the sake of simplicity is not shown in the drawing.

Når renserullerne 38 til 44 drives, bevæger roerne sig gennem føringsriller, der dannes af to samvirkende renseruller. Skovlvindinger 46 på hver renserulle 38 til 44 bevirker, at roerne omtumles, skrubbes og føres videre i retning mod en rensetromle 58, som findes ved højre side af roehøsteren 10. Ved denne 4 148341 tumlebevægelse af roerne fjernes snavs, bladrester eller lignende dele fra roerne og falder mellem rullerne ned på jorden.When the cleaning rollers 38 to 44 are driven, the beets move through guide grooves formed by two cooperating cleaning rollers. Shovel windings 46 on each cleaning roller 38 to 44 cause the beets to tumble, scrub and advance in the direction of a cleaning drum 58 located at the right side of the beet harvester 10. This tumbling movement of the beets removes dirt, leaf residue or similar parts from the beets. and falls between the rollers to the ground.

Roerne afgives i sideretningen af transportøren 36 og rense-tromlen 58. Til frembringelse af en sideværts bortledningstransportør har transportøren 36 en afleveringsrulle, som udgøres af delen 54. Afleveringsdelen 54 forløber koaksialt med renserullen 40 og er lejret i rullelejer 60 og 62, som tillader, at den drives i modsat omdrejningsretning af renserullen 40. Når roerne transporteres mellem renserullerne 38 og 40 samt 42 og 44 og når hen til bortledningsområdet oven over rensetromlen 58, drives renserullerne 38 og 42 i den ved pilene i fig. 3 viste omdrejningsretning, og afleveringsrullen 54 drives i samme retning for at transportere roerne fra siden ind i maskinens bagéste del og bort fra transportøren 36.The beets are discharged laterally by the conveyor 36 and the cleaning drum 58. To produce a lateral discharge conveyor, the conveyor 36 has a delivery roller which is formed by the part 54. The delivery part 54 extends coaxially with the cleaning roller 40 and is mounted in roller bearings 60 and 62, which allow that it is driven in the opposite direction of rotation by the cleaning roller 40. When the beets are transported between the cleaning rollers 38 and 40 and 42 and 44 and reach the discharge area above the cleaning drum 58, the cleaning rollers 38 and 42 are driven in it by the arrows in fig. 3, and the delivery roller 54 is driven in the same direction to transport the beets from the side into the rearmost part of the machine and away from the conveyor 36.

De ved siden af hinanden liggende renseruller 38 og 42 har nogle modsat løbende skovlvindinger 64 for at vende bevægelsesretningen af roerne på transportøren 36. Afleveringsrullen 54 er forsynet med en glat overflade, så de to renseruller 38 og 42 bevæger roerne bagud under omtumling. Om ønsket kan afleveringsrullen 54 ligeledes være forsynet med skrueformede skovlvindinger, som understøtter tumlebevægelsen af roerne.The adjacent cleaning rollers 38 and 42 have some oppositely running vane windings 64 for reversing the direction of movement of the beets on the conveyor 36. The delivery roller 54 is provided with a smooth surface so that the two cleaning rollers 38 and 42 move the beets rearward during tumbling. If desired, the delivery roller 54 may also be provided with helical vane windings which support the tumbling movement of the beets.

Ved hjælp af de frembragte retningsændringer af omstyredelen af renserullerne 38 og 42 i forbindelse med afleveringsrullen 54 og de modsat rettede skrueformede skovlvindinger 64 stoppes en tværbevægelse af roerne hen langs transportrenderne, og der frembringes en tumlelignende bevægelse af roerne bagud i maskinens længderetning.By means of the changes of direction produced by the deflection part of the cleaning rollers 38 and 42 in connection with the delivery roller 54 and the oppositely directed helical vane windings 64, a transverse movement of the beets along the transport gutters is stopped and a tumble-like movement of the beets rearward in the longitudinal direction of the machine.

Til optagelse af enden af renserullen 44 findes .et rulleleje 66, som er anbragt i en forreste rammedel 68. Renserullen 44 ender ved den nærmeste side af rensetromlen 58, så den " kan afgive de i .transportrenden mellem renserullerne 42 og 44 transporterede roer til rensetromlen 58.To receive the end of the cleaning roller 44, there is a roller bearing 66 which is arranged in a front frame part 68. The cleaning roller 44 ends at the nearest side of the cleaning drum 58 so that it can "deliver the tubes transported in the transport trough between the cleaning rollers 42 and 44 to the cleaning drum 58.

Claims

148341 The bearings 70,62,72, the support mechanism for the cleaning rollers 38 and 42 and the delivery roller 54 are spaced apart from the outside by two upright plates 74 and 78. Their respective shafts 48,50 and 76 extend through the plate 74. When the beets are guided to the end of the conveyor 36, the plates 74 and 78 serve to collect them and prevent dirt and other parts scraped off from the beets from getting stuck somewhere and thus be able to soil or block the bearings. To drive a sprocket 80 attached to the shaft 76, there is a chain 82 which is in drive communication with a sprocket 84 which is mounted on the shaft 48 of the cleaning roller 38. The shaft 48 is driven at its opposite end indirectly or directly from an on the drawing does not show the tractor PTO shaft. After the beets have been brought up from the cleaning drum 58, they are discharged over a transverse conveyor 86 (Fig. 1) from the machine, e.g. to a truck. The transverse conveyor 86 is also designed so that it can guide the beets inwards to a collecting container, which can be arranged on the beet harvester 10. Patent claim.
