Description

Potetopptaker. Potato picker.

Foreliggende oppfinnelse angår en potetopptaker med en ringformet transportrist, som er dreibar om en skrått fremover heldende akse og har form som en avkortet kjegleflate med nedadvendende topp-punkt, samt en i hovedsaken sylindrisk indre begrensningsvegg som slutter seg til transportristens indre periferi og hvor det videre er anordnet organer for tilledning av oppgravede poteter til transportristen i dennes nederste område og til å bevirke avgang av potetene ved transportristens indre periferi i transportristens øverste område. The present invention relates to a potato harvester with an annular transport grate, which can be rotated about an obliquely forward inclined axis and has the shape of a truncated cone surface with a downward-facing top point, as well as a mainly cylindrical internal limiting wall which joins the inner periphery of the transport grate and where the further organs are arranged for supplying excavated potatoes to the transport grate in its lowermost area and for causing the potatoes to depart at the inner periphery of the transport grate in the upper area of the transport grate.

Det er kjent en potetopptaker av denne art, ved hvilken transportristens riststenger er fast anbragt og strekker seg i transportristens omkretsretning, mens innerveg-gen består av en ubrudt sylindrisk vegg, ved hvis fot der finnes huller, som holdes tildekket av en under transportristen anbragt lukkeplate under transportristens oppadgående bevegelse, mens de i transportristens øverste område frigis, slik at potetene kan gli nedover transportristen og avgis ved dennes indre periferi. A potato receiver of this type is known, in which the grate bars of the transport grate are fixed and extend in the circumferential direction of the transport grate, while the inner wall consists of an unbroken cylindrical wall, at the foot of which there are holes, which are kept covered by a closing plate placed under the transport grate during the upward movement of the transport grate, while those in the top area of the transport grate are released, so that the potatoes can slide down the transport grate and be released at its inner periphery.

Ved denne kjente konstruksjon er der fare for, at en del forurensninger, såsom røtter og plantedeler, kan bli hengende på risten ved uttømmingen, liksom sten har mulighet for å klemme seg inn mellom riststengene, og bli hengende der. I ugunstige tilfelle kan også noen poteter bli tilbake, da uttømmingen foregår gjennom de rela-tivt små åpninger ved riststengenes indre periferi. With this known construction, there is a risk that some contaminants, such as roots and plant parts, may become suspended on the grate during emptying, just as stones have the opportunity to squeeze in between the grate bars and remain suspended there. In unfavorable cases, some potatoes may also remain, as the emptying takes place through the relatively small openings at the inner periphery of the grate bars.

Foreliggende oppfinnelse går ut på å avhjelpe disse mangler, og det karakteris- The present invention seeks to remedy these shortcomings, and the characteristic

tiske trekk ved oppfinnelsen består i at transportristen er sammensatt av seksjoner, som hver for seg består av en ved transportristens ytre periferi deibart lagret bærestang, fra hvilken et antall riststenger strekker seg innad mot transportristens midte. technical feature of the invention is that the transport grate is composed of sections, each of which consists of a supporting rod firmly placed at the outer periphery of the transport grate, from which a number of grate rods extend inwards towards the center of the transport grate.

Ved denne utformning av transportristen fremkommer der i dennes øverste område en meget stor åpning, gjennom hvilken potetene og forurensningene kan gli ned, og der finnes ikke konstruksjonsdeler, på hvilke poteter eller forurensninger kan bli hengende, idet glidningen fra transportristen skjer i riststengenes lengderet-ning og med disse i fritt nedhengende stilling, slik at de kan gi etter for materiale, som presser på. With this design of the transport grate, a very large opening appears in its uppermost area, through which the potatoes and contaminants can slide down, and there are no structural parts on which potatoes or contaminants can become suspended, as the sliding from the transport grate takes place in the longitudinal direction of the grate bars and with these in a freely hanging position, so that they can give way to material that presses on.

Oppfinnelsen skal i det følgende be-skrives nærmere under henvisning til tegningen hvor In the following, the invention will be described in more detail with reference to the drawing where

fig. 1 skjematisk viser en utførelses-form for en potetopptaker ifølge oppfinnelsen, sett fra siden og delvis i snitt, og fig. 1 schematically shows an embodiment of a potato harvester according to the invention, seen from the side and partially in section, and

fig. 2 viser transportristen, sett oven-fra i skrå retning, vinkelrett på dens plan. fig. 2 shows the transport grate, viewed from above in an oblique direction, perpendicular to its plane.

På tegningen betegner 101 en ringformet transportrist, som på ikke nærmere angitt måte er dreibart lagret i en maskin-ramme 102 omkring en skrå akse 103. Transportristen omfatter et antall seksjoner 104, som hver for seg er formet som en rist bestående av et antall riststenger, som er rettet skrått innad i forhold til ristens plan, således at de tilsammen kommer til å danne en svakt konisk flate med nedadvendende topp-punkt. Ved den ytter-ste ende er riststengene i hver seksjon for-bundet med en stang 105, som er dreibart lagret i lågere 106, som bæres av en sirku-lær stang langs ristens periferi. Seksjonene er således dreibart lagret ved ristens om-krets. Til hver av seksjonene hører der en slipphake 108, som er dreibart lagret på en til risten hørende ring 109, innen for seksjonen og normalt holder seksjonene i den i fig. 1 med fullt opptrukne linjer viste stilling. Innenfor seksjonene er der på rin-gen 109 montert en sylindrisk rist bestående av riststenger 110, som er skråttstillet nedover og bakover i ristens omdrei-ningsretning. Denne sylindriske rist dan-ner, når seksjonene er i transportstilling, en indre begrensningsvegg for det på disse liggende materiale. In the drawing, 101 denotes an annular transport grate, which is rotatably stored in a machine frame 102 around an inclined axis 103 in a manner not specified. The transport grate comprises a number of sections 104, each of which is shaped as a grate consisting of a number of grate bars , which are directed obliquely inwards in relation to the plane of the grating, so that together they will form a slightly conical surface with a downward-facing top point. At the outermost end, the grating bars in each section are connected with a rod 105, which is rotatably stored in bearings 106, which is carried by a circular rod along the periphery of the grating. The sections are thus rotatably stored at the perimeter of the grating. To each of the sections there belongs a release hook 108, which is rotatably stored on a ring 109 belonging to the grate, inside the section and normally holds the sections in it in fig. 1 with solid lines showing position. Within the sections, a cylindrical grate is mounted on the ring 109 consisting of grate bars 110, which are inclined downwards and backwards in the direction of rotation of the grate. This cylindrical grating forms, when the sections are in the transport position, an internal limiting wall for the material lying on them.

111 betegner et opptaker jern, ved hjelp av hvilket potetene graves opp av jorden, og fra hvilket de passerer inn på ristens seksjoner i nærheten av ristens nederste punkt. Potetene og den medfølgende jord, samt de medfølgende stener transporteres nu oppad hvilende i mellomrommet mellom seksjonene og den sylindriske rist 110, hvorved de samtidig underkastes en rullen-de bevegelse, som bidrar til en begynnende siktning. Eventuelt kan der ved den oppadgående del av risten eller en del av denne uten for risten være anbragt ledeskin-ner for å hindre en utslyngning av potetene fra risten. Etterhånden som hver seksjon kommer opp i nærheten av sin øverste stilling, utløses dens slipphake 108 på ikke nærmere måte, hvorved seksjonen frigis og svinger ut i den med stiplet linje viste stilling i fig. 1. Det materiale, som i for- 111 denotes a pick-up iron, by means of which the potatoes are dug up from the earth, and from which they pass onto the sections of the grate near the lowest point of the grate. The potatoes and the accompanying soil, as well as the accompanying stones, are now transported upwards resting in the space between the sections and the cylindrical grate 110, whereby they are simultaneously subjected to a rolling movement, which contributes to a beginning sifting. Optionally, guide rails can be placed at the upward part of the grate or a part of it outside the grate to prevent the potatoes from being thrown from the grate. As each section comes up near its uppermost position, its release hook 108 is triggered in no further manner, whereby the section is released and swings out into the position shown by the dashed line in fig. 1. The material, which in

veien hvilte mellom den angjeldende seksjon og den sylindriske rist 110, kan nu av-gå fra bunnen av det mellom seksjonen og den sylindriske rist dannede rom og faller derved ut på en skråttstillet slisk 112. Under den videre passasje kommer seksjonen hen i området for en rulle 113, som svinger the road rested between the relevant section and the cylindrical grate 110, can now depart from the bottom of the space formed between the section and the cylindrical grate and thereby fall out onto an inclined chute 112. During the further passage, the section comes into the area of a roll 113, which swings

seksjonen tilbake til den med fullt opptrukne linjer viste stilling, i hvilken den atter fanges av sin slipphake. the section back to the position shown in solid lines, in which it is again caught by its release hook.
