Opfindelsen angår en kartoffeloptager med et endeløst, roterbart drevet sigtetransportbånd, der slutter sig til en optageindretning, og som er ført via omstyreindretninger og består af et antal tværstave, hvis ender 5 er fastgjort til langsgående, udvendigt liggende bæreremme, og hvor kartoffeloptagerens bagtil anbragte om-styreindretning, som vender bort fra optageindretningen, udgøres af et driv- og omstyrelegeme, der er lejret drejeligt i maskinstativet og er forbundet med et drev, 10 og som strækker sig i hovedsagen over bredden af sigte-transportbåndet .BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a potato recorder having an endless, rotatably driven sieve conveyor belt which joins a recording device and is guided by means of diverting means and consists of a plurality of transverse rods, the ends of which are attached to longitudinal, outer bearing straps and the rear of the potato recorder control device facing away from the receiving device is constituted by a drive and steerer body which is pivotally mounted in the machine frame and is connected to a drive 10 extending substantially over the width of the sieve conveyor belt.
Ved kendte kartoffeloptagere af denne art består den bagtil anbragte omstyreindretning af en valseformet drivkurv, som på endeskiver har påsvejste, aksiale kurv-15 stave, der danner understøtning for sigtetransportbåndet i omstyreområdet. Kurvstavenes vinkelafstand er afstemt efter afstanden mellem sigtetransportbåndets tværstave, og ved drivkurvens rotation indgriber kurvstavene i mellemrummene mellem sigtetransportbåndets tværstave, hvor-20 ved kurvstavene griber som drivmedbringer bag hver sin tilhørende tværstav af sigtetransportbåndet. I det omløbende omstyreområde virker kurvstavene samtidig som fyldestave, som formindsker den fri afstand mellem sigtetransportbåndets tværstave. Drivkurven kan have yder-25 ligere, langsgående fyldestave, der ikke virker som drivmedbringer, men som tjener til at formindske gennemgangsspalter, idet de i omstyreområdet danner bro over lysningsafstanden mellem op til hinanden grænsende stave.In known potato recorders of this kind, the rearrange device located in the rear consists of a roll-shaped drive basket which has welded axial basket rods on end discs which provide support for the sieve conveyor belt in the redirection area. The angular distance of the curving rods is aligned with the distance between the sieve conveyor belt and the rotation curve of the drive basket engages in the spaces between the sieve conveyor's cross rods, whereby the basket rods act as a driving carrier behind each associated cross bar of the sieve conveyor belt. In the circumferential diverting area, the basket rods act simultaneously as filler rods, which reduce the free distance between the sieve conveyor belts. The drive curve may have additional longitudinal filling rods which do not act as a drive carrier, but serve to reduce throughput gaps as they bridge the clearance distance between adjacent rods.
30 En sådan omstyreindretning bevirker, at der under kartoffeloptagerens drift udvikles en betydelig støj, og forårsager et fremadskridende slid på sigtetransportbån-det, især på dets tværstave, hvorved kurvstavene udsættes for slid. Selv ved en nøjagtig afstemning af kurv-35 stavenes omkredsafstande efter sigtetransportbåndets tværstave forekommer det stadig, at sigtetransportbåndets tværstave løber ind på kurvstavene, så der opstår støjfænomener. Også samvirkningen mellem den bagtil 2Such a switching device causes a considerable noise to develop during operation of the potato recorder and causes a progressive wear on the sieve conveyor belt, especially on its transverse rods, thereby exposing the basket rods to wear. Even by accurately matching the circumferential distances of the basket rods to the transverse rods of the sieve conveyor belt, it still seems that the transverse rods of the sieve conveyor belt run into the basket rods to produce noise phenomena. Also the interaction between the rear 2

liggende omstyreende af sigtetransportbåndet og en derefter anbragt/ fjederpåvirket kartoffeltop-plukkevalse er ved udformning af den bagtil anbragte omstyreindretning som drivkurv ofte utilfredsstillende/ især da kar-5 toffeltop-plukkevalsen ved løb af sigtetransportbåndets tværstave på kurvstavene kommer til at bevæge sig med støj over tværstavene og får sin virkning reduceret og udsættes for slid i sin valselejring og sine anpresnings-midler.lying down about the sieve conveyor belt and a subsequently applied / spring-influenced potato top picking roller is often unsatisfactory when designing the rear steering device as a driving basket / especially as the potato top picking roller comes in contact with the sieve conveyor cross bars on the cross conveyor bars during running of the sieve conveyor belt. and has its effect reduced and subjected to wear in its roller bearing and its pressing means.
10 Opfindelsen afhjælper disse ulemper ved, at driv- og omstyrelegemet er dannet af en cylindrisk tromle, som på sin overflade i sit med sigtetransportbåndets tværstave samvirkende omkredsområde har en kappe, der består af gummi eller lignende elastisk eftergiveligt 15 materiale, hvilken kappe har en tykkelse, som er lig med eller større end diameteren af sigtetransportbåndets tværstave og fortrinsvis andrager ca. 15 til 20 mm.The invention alleviates these drawbacks in that the drive and steering body is formed by a cylindrical drum having on its surface a circumferential region cooperating with the cross-bar of the sieve conveyor belt, a jacket consisting of rubber or similar elastically resilient material, which sheath has a thickness. which is equal to or greater than the diameter of the sieve conveyor belt's cross bars and preferably amounts to approx. 15 to 20 mm.
Yderligere udføreisesformer for kartoffeloptageren 20 ifølge opfindelsen fremgår af kravene 2-13.Further embodiments of the potato pickup 20 of the invention are set forth in claims 2-13.
Tromlen, der på omkredsen har en kappe af efter-giveligt materiale, garanterer ved støjsvagt, roligt løb en sikker medtagelse af sigtetransportbåndets tværstave, som kommer i indgreb med tromlens kappe, og som i omsty-25 reområdet lægger sig fast mod kappen og trykker sig ind i denne. Kappen lukker fuldstændigt mellemrummene mellem sigtetransportbåndets tværstave og muliggør en nøjagtig og direkte anstilling af en kartoffeltop-plukkevalse mod den tilhørende omstyreende af sigtetransportbåndet, hvor-30 ved denne valse kommer til at arbejde på en bedre måde og samtidig uden støjfænomener. Den særligt gode og ensartede understøtning af tværstavene modvirker bøjningsfænomener, så der skabes mulighed for anvendelse af forholdsvis tynde tværstave. Dertil kommer, at delene af 35 sigtetransportbåndet såvel som delen af en eventueltThe drum, which has a sheath of resilient material on the perimeter, guarantees, by quiet, quiet running, a safe inclusion of the cross-bar of the sieve conveyor belt, which engages with the sheath of the drum, which attaches itself to the sheath in the steer area into this one. The jacket completely closes the gaps between the sieve conveyor belts and allows an accurate and direct alignment of a potato top pick roller against the associated overthrow of the sieve conveyor belt, whereby this roller will work in a better way and at the same time without noise phenomena. The particularly good and uniform support of the transverse rods counteracts bending phenomena, allowing the use of relatively thin transverse rods. In addition, the portions of the sieve conveyor belt as well as the portion of one optionally

3 derefter anbragt kartoffeltop-plukkevalse er udsat for væsentligt mindre påvirkninger med deraf følgende væsentligt højere levetid. I tilfælde, hvor sigtetrans-portbåndet må udskiftes med sigtetransportbånd med an-5 den stavdeling - for at tage hensyn til forskellige betingelser for kartoffeloptageprocessen - kan dette ske på en særlig let og enkel måde, idet den bagtil anbragte omstyreindretning, som driver sigtetransportbåndet, ikke skal medudskiftes ved transportbåndsombyt-10 ningen. Da tromlen med den derpå anbragte kappe udøver en forholdsvis høj drivvirkning på sigtetrans-portbåndet, kan de udvendigt liggende bæreremme i mange tilfælde have en underside, som er fri for med-bringerknaster. Udskiftningen af sigtetransportbåndet 15 kan foregå særlig nemt, når tromlerne ved hver ende har en koaksial omstyreskive, over hvilken der passerer en udvendigt liggende bærerem, og som kan påflanges som udskiftelig del på tromlen. Dette skaber mulighed for, at man i særlige tilfælde kun behøver at med-20 udskifte omstyreskiverne for tilpasning til den pågældende udformning af bæreremmene, medens tromlen og dens kappe forbliver uændret.3, then potato top pick rollers are subjected to substantially smaller stresses, resulting in substantially higher service life. In cases where the sieve conveyor belt has to be replaced by sieve conveyor belt with another rod - to take into account different conditions for the potato picking process - this can be done in a particularly easy and simple way, since the rear-mounted control device which drives the sieve conveyor belt does not must be co-replaced with the conveyor belt change. Since the drum, with the sheath mounted thereon, exerts a relatively high driving effect on the sieve conveyor belt, the exterior bearing straps may in many cases have a underside which is free of carrier cracks. Replacement of the sieve conveyor belt 15 can be particularly easy when the drums have at each end a coaxial guide disc over which an outer bearing strap passes and which can be flanged as a replaceable part of the drum. This creates the possibility that in special cases it is only necessary to replace the guide discs for adaptation to the particular design of the straps, while the drum and its casing remain unchanged.
Ved anvendelsen af yderligere drivruller, som overfører deres drivkræfter til sigtetransportbåndets 25 bæreremme, overtager disse drivruller en del af de samlede drivkræfter, som er nødvendige for drivningen af sigtetransportbåndet. Derved formindskes de drivkræfter, som skal overføres fra tromlen til sigtetransportbåndet, og der skabes mulighed for at reducere 30 tromlens diameter betydeligt. Ved anbringelse af de yderligere drivruller nær ved tromlen for drivindgreb med bæreremmene i området af sigtetransportbåndets tilbageløbende tomme båndpart opnås der en særligt pladsbesparende udformning, og endvidere bibringes sidetrans-35 portbåndet en afbøjning, som forøger sigtetransport- 4By using additional drive rollers which transmit their driving forces to the carrier belts of the sieve conveyor belt, these drive rollers assume part of the total driving forces necessary for the operation of the sieve conveyor belt. Thereby, the driving forces to be transferred from the drum to the sieve conveyor belt are reduced and the possibility of reducing the diameter of the drum is significantly reduced. By placing the additional drive rollers near the drum for drive engagement with the support belts in the region of the receding empty belt portion of the sieve conveyor belt, a particularly space-saving design is obtained, and furthermore a deflection is provided which increases the sieve conveyor belt 4.

Kartoffeloptagere af den 10 beskrevne art er kendt i talrige udførelser.the rear diverting device shown, where the potatoes are transferred to a further conveyor not shown, while a potato top picking or remote roller 2, which cooperates with the rear guide 5 of the sieve conveyor belt, separates at least a substantial part of the potato peaks from the potatoes, for example, these potato peaks squeeze between themselves and the screen conveyor belt 1 diverting and passing them separately from the potatoes to a potato top assembly conveyor. Potato harvesters of the type described are known in numerous embodiments.
Sigtetransportbåndet 1 er udformet endeløst og drives roterende via en fortil anbragt, ikke nærmere vist omstyreindretning, som grænser op til optageindretningen, såvel som via en bagtil anbragt omstyreindret-15 ning, som vender bort fra optageindretningen, og, som overtager drivningen af sigtetransportbåndet 1. Sigtetransportbåndet 1 består af et antal tværstave 3, hvis ender 4 er fastgjort, f.eks. nittet, til langsgående, udvendigt liggende bæreremme 5, 6. I den viste 20 udførelsesform for sigtetransportbåndet 1 er der desuden i midterområdet anbragt en langsgående mellembære-rem 7, som tjener til yderligere føring og distancering af de gennemgående tværstave i deres midterområde. Denne udførelse med mellembærerem finder navnlig anvendelse 25 ved sigtetransportbånd 1, som er særligt brede, således som det er tilfældet ved sigtetransportbånd for toskær- optageindretninger til kartoffeloptagere. Sigtetransportbånd af en sådan udformning er kendt i talrige udførelser.The sieve conveyor belt 1 is designed endlessly and is rotatably driven via a front positioning device, not shown, adjacent to the recording device, as well as via a rearwardly directed rearrangement device away from the recording device and which takes over the drive of the sieve conveyor belt 1. The sieve conveyor belt 1 consists of a plurality of transverse rods 3 whose ends 4 are secured, e.g. In addition, in the illustrated embodiment of the sieve conveyor belt 1, a longitudinal intermediate carrier belt 7 is provided, which serves for further guiding and spacing of the transverse rods in their middle region. In particular, this medium-carrier belt design applies to sieve conveyor belts 1, which are particularly wide, as is the case with sieve conveyor belts for dual cutter potato pickup devices. Sieve conveyor belts of such a design are known in numerous embodiments.
30 Den bageste omstyreindretning, der i sin helhed er betegnet 8, omfatter et driv- og omstyrelegeme, som strækker sig i hovedsagen over bredden af sigtetransportbåndet 1, og som er forbundet med ikke nærmere viste drivmidler. Driv- og omstyrelegemet er i hovedsagen 35 dannet af en cylindrisk tromle 9, som på sin overfla- 6The rear diverting device, designated in its entirety 8, comprises a driving and reversing body which extends substantially over the width of the sieve conveyor belt 1 and which is connected to propellants not shown. The drive and steering body is generally formed by a cylindrical drum 9 which on its surface

de i sit med sigtetransportbåndet l's tværstave 3 samvirkende omkredsområde har en kappe 10, der består af gummi eller lignende elastisk eftergiveligt materiale.the circumferential region of the transverse region cooperating with the sieve conveyor belt 1 has a sheath 10 consisting of rubber or similar elastic resilient material.
I den viste udførelse af sigtetransportbåndet 1 med 5 langsgående mellembærerem 7 er kappen afbrudt i området af mellembæreremmen 7, og i det afbrudte område II danner tromlen 9 direkte en løbeflade for mellembæreremmen 7.In the illustrated embodiment of the sieve conveyor belt 1 with 5 longitudinal middle carrier belt 7, the sheath is broken in the region of the middle carrier belt 7 and in the interrupted area II the drum 9 directly forms a running surface for the middle carrier belt 7.
Kappen 10 kan bestå af et homogent materiale 10 eller af skumstof, i hvilket tilfælde skumstoffet har en lukketporet overflade. Tykkelsen af kappen 10 er fortrinsvis lig med eller større end diameteren af sigtetransportbåndet l’s tværstave 3 og andrager fordelagtigt ca. 15 til 20 mm. Kappen er enten udformet som en 15 separat del og er klæbet eller vulkaniseret på tromlen 9, som består af metal, eller den danner et lag, som f.eks. er påskummet direkte eller på anden måde anbragt på tromlen 9's overflade.The jacket 10 may consist of a homogeneous material 10 or of foam, in which case the foam has a closed-pore surface. The thickness of the casing 10 is preferably equal to or greater than the diameter of the sieve conveyor belt 1's transverse rods 3 and advantageously amounts to approx. 15 to 20 mm. The sheath is either formed as a separate part and is bonded or vulcanized to the drum 9, which is made of metal, or it forms a layer, e.g. is foamed directly or otherwise disposed on the surface of the drum 9.
I den i fig. 1 viste udførelsesform har tromlen 20 9 ved sine to ender en koaksial omstyreskive 12, over hvilken der løber en udvendigt liggende bærerem 5 respektive 6, og som er dannet af et ringformet gitterlegeme, som har en afbrudt løbeflade for den tilhørende bærerem, hvilken løbeflade er dannet af et antal koaksia-25 le ribber 13, som er anbragt under en og samme vinkel om omkredsen. En sådan udformning af omstyreskiven anvendes til sigtetransportbåndudførelser, som har bæreremme 5, 6, på hvis underside der er udformet medbrin- gerknaster 14. Afstandene mellem omstyreskiverne 12's 30 tværribber 13 kan let og nøjagtigt afpasses efter dimensionerne af og afstandene mellem medbringerknaster-ne 14, så der i dette område praktisk taget ikke er risiko for påløb.In the embodiment shown in FIG. 1, the drum 209 has at its two ends a coaxial guide disc 12 over which runs an outer bearing belt 5 and 6, respectively, and which is formed by an annular grating body having an interrupted running surface for the associated support belt, which running surface is formed by a plurality of coaxial ribs 13 disposed at one and the same angle around the circumference. Such a design of the guide disc is used for screen conveyor belt designs having support belts 5, 6, on the underside of which are formed carrier brackets 14. The distances between the cross ribs 13 of the guide discs 30 can be easily and accurately adjusted to the dimensions of and the distances between the carrier knobs 14, so there is practically no risk of accrual in this area.

7 I stedet for de i fig. 1 og 2 viste omstyreskiver 12, der er udført som ringformede gitterlegemer, kan omstyreskiverne have form af en cylindrisk, på overfladen lukket ringdel 15, fig. 3, som desuden kan have 5 en klæbebelægning 16, fig. 4, på sin overflade. Sådanne udførelser af omstyreskiverne er først og fremmest bestemt for sigtetransportbånd med bæreremme, der - som ved sigtetransportbåndudføreiserne ifølge fig. 2 til 4 - på deres underside har en i hovedsagen glat løbeflade, som 10 er fri for medbringerknaster.7 Instead of the ones in FIG. 1 and 2, which are shown as annular grating bodies 12, the guide discs may be in the form of a cylindrical, surface-closed ring member 15; 3, which may additionally have 5 an adhesive coating 16; 4, on its surface. Such embodiments of the guide discs are first and foremost intended for screen conveyor belts with carrying straps which - as in the screen conveyor belt embodiments of FIG. 2 to 4 - on their underside has a generally smooth running surface which 10 is free of carrier lugs.
Omstyreskiverne 12, 15 er udformet som separate dele, som kan fastgøres udskifteligt på tromlen 9's ender, for at der alt efter behov kan kombineres forskellige omstyreskiver 12, 15 for en og samme tromle 159 og kappe 10. I den viste udførelsesform har tromlen 9 endesidige radiale flangeskiver eller -ringe 17, på hvilke omstyreskiverne 12, 15 kan påflanges. Dertil kommer, at der på tromlen 9's flangeskiver eller -ringe 17 også kan påflanges drivakselstykker 18, 19, 20 som ved deres indre ender bærer tilsvarende flangeskiver 20.The guide discs 12, 15 are formed as separate parts which can be interchangeably fastened to the ends of the drum 9, so that, as needed, different guide discs 12, 15 can be combined for one and the same drum 159 and sheath 10. In the embodiment shown, the drum 9 has one-sided radial flange discs or rings 17 on which the guide discs 12, 15 can be flanged. In addition, on the flange discs or rings 17 of the drum 9, drive shaft pieces 18, 19, 20 can also be flanged on their inner ends, which carry corresponding flange discs 20.
Yderdiameteren af omstyreskiverne 12, 15, dvs.The outer diameter of the guide discs 12, 15, ie.
diameteren af deres løbeflade, er mindre end yderdiameteren af kappen 10, for at man kan tage hensyn til 25 afstandsforholdene mellem bæreremmene 5, 6's inder- flade og undersiderne af sigtetransportbåndet l's tværstave 3.the diameter of their running surface is smaller than the outer diameter of the casing 10, in order to take into account the distance ratios between the inner surface of the support belts 5, 6 and the undersides of the transverse rods 3 of the sieve conveyor belt 1.
Den i fig. 1 skematisk viste kartoffeltop-plukke-valse 2 er af en vilkårlig egnet udformning og er sæd-30 vanligvis lejret endesidigt i svingindretninger, der ved hjælp af tryk- eller trækfjedre står under en forspæn-ding, som i det bageste omstyreområde presser kartoffel-top-plukkevalsen 2 mod sigtetransportbåndet l's omkreds. Kartoffeltop-plukkevalsen kan være af en vil-35 kårlig kendt eller egnet udformning.The FIG. 1 schematically shown potato top pick roller 2 is of any suitable design and is usually mounted unilaterally in pivoting devices which, by means of compression or tension springs, are under a bias which in the rear control area presses potato top picking roller 2 against the circumference of the sieve conveyor belt 1. The potato top pick roll may be of any known or suitable design.

Ved udførelsesf omen ifølge fig. 5 og 6 er der nær ved tromlen 9 anbragt yderligere drivruller 21, som samvirker med bæreremmene 5, 6 og eventuelt også med bæreremmen 7. Af disse drivruller 21 er der kun 5 vist den drivrulle, som samvirker med bæreremmen 5.In the embodiment of FIG. 5 and 6, additional drive rollers 21 are provided adjacent to the drum 9 which cooperate with the carrier belts 5, 6 and possibly also with the carrier belt 7. Of these drive rollers 21, only 5 are shown the drive roller which cooperates with the carrier belt 5.
Samtlige drivruller 21 er anbragt på en fælles drivaksel 22, der strækker sig koaksialt med tromlen 9 og drives af en drivoverføringsindretning 23, antydet skematisk i fig. 6. Drevet for drivrullerne 21 afledes 10 hensigtsmæssigt fra tromlen 9's drivkilde.All drive rollers 21 are disposed on a common drive shaft 22 extending coaxially with the drum 9 and driven by a drive transfer device 23, indicated schematically in FIG. 6. The drive for the drive rollers 21 is conveniently derived from the drive source of the drum 9.
I den viste udførelsesform er drivrullerne 21 anbragt nær ved tromlen 9 på en sådan måde, at de i området af sigtetransportbåndet l's tomme båndpart 24 står i drivindgreb med den til dan hørende bærerem 5, 15 6 respektive 7. Den tomme båndpart 24 danner den del af sidetransportbåndet 1, som fra tromlen 9 løber under den øvre arbejdsbåndpart 25 tilbage til den ikke viste forreste omstyreindretning.In the illustrated embodiment, the drive rollers 21 are positioned close to the drum 9 in such a way that they engage in the region of the empty belt portion 24 of the sieve conveyor belt 1 with the associated belt 5, 15 and 7 respectively. The empty belt portion 24 forms that part of the side conveyor belt 1, which runs from the drum 9 below the upper work belt portion 25 back to the front forwarding device not shown.
Placeringen’’af drivrullerne 21 er valgt således, 20 at de - på grund af deres drivindgreb med bæreremmene 5,6 respektive 7 - i et i løberetning bag ved tromlen 9 liggende område bibringer sigtetransportbåndet 1 en mod arbejdsbåndparten 25 rettet afbøjning 26, som forøger sigtetransportbåndet l's tromleomslyngnings-25 vinkel med et stykke, som overstiger 180°. Drivrullerne 21 bevirker med andre ord, at sigtetransportbåndet l's tomme båndpart 24 - i drivrullerne 2l's indgrebsområde med sigtetransportbåndet 1 - kommer til at ligge i en afstand i forhold til sigtetransportbåndet l's 30 arbejdsbåndpart 25, som er mindre end den virksomme diameter af tromlen 9.The positioning of the drive rollers 21 is selected such that, due to their drive engagement with the support belts 5,6 and 7, respectively, in a running direction behind the drum 9, the sieve conveyor belt 1 imparts a deflection 26 directed towards the working belt part 25 which increases the sieve conveyor belt 1's drum winding angle with a piece exceeding 180 °. In other words, the drive rollers 21 cause the empty belt portion 24 of the sieve conveyor belt 1 - in the engagement area of the drive rollers 2l with the sieve conveyor belt 1 - to be spaced from the working belt portion 25 of the sieve conveyor belt 30 which is smaller than the effective diameter of the drum 9.
Alt efter udformningen af ydersiden af bæreremmene 5, 6 respektive 7 kan drivrullerne 21 på deres ydre omkreds have en profil, som forøger drivmedtagelsen af 35 bæreremmene, eller de kan på omkredsen hav en elastiskDepending on the design of the outside of the support belts 5, 6 and 7, respectively, the drive rollers 21 on their outer circumference may have a profile which increases the drive engagement of the support belts or they may have an elastic at the periphery.
