Opfindelsen angår et apparat til ændring af afstanden mellem en mejetærskers tærskecylinder og mindst ét på en tærskekurv drejeligt lejret tærskekurvsegment med et ved den ene ende af tærskekurven tilsluttet indstillingsorgan, som kan ind-5 stilles imod virkningen af en af en fjeder udøvet justerkraft, hvorhos tærskekurven kan drejes sammen med et eller flere tærskekurvsegmenter ved hjælp af en yderligere indstillingsindretning, og tærskekurvsegmentet eller -segmenterne er drejeligt lejret på en ramme hørende til tærskekurven.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an apparatus for altering the distance between a combine's threshing cylinder and at least one threshing basket pivotally mounted on a threshing basket having an adjusting means connected at one end of the threshing basket which can be set against the action of a adjusting thrust exerted by a spring can be rotated together with one or more threshing basket segments by a further adjusting device, and the threshing segment (s) is pivotally mounted on a frame belonging to the threshing basket.

Fra U.S. patent nr. 2.053.148 kendes en stationær tærskemaskine, hvis nedre tærskekurv består af to tærskekurvsegmenter, som ved deres over for hinanden liggende ender hver er forbundet med en indstillingsindretning, så at de to tærskekurv-15 segmenter i forhold til tærskekurven i radialretningen kun kan indstilles i fællesskab ved hjælp af indstillingsindretningen for derved at ændre spaltebredden mellem tærskecylin-deren og tærskekurven. Derudover kan det enkelte tærskekurvsegment med denne indretning ikke selvstændigt tilpasses til 20 cylinderen, især da ikke, når korngennemgangen ved tærskningen pludselig bliver ændret.From the U.S. Patent No. 2,053,148 is known to a stationary threshing machine, the lower threshing basket of which consists of two threshing basket segments, each at opposite ends of which are connected to a setting device, so that the two threshing basket segments can only with respect to the threshing basket in the radial direction. is adjusted jointly by means of the adjusting device, thereby changing the gap width between the threshing cylinder and the threshing curve. In addition, the individual threshing-basket segment with this device cannot be independently adapted to the cylinder, especially since when the grain passage at the threshing is suddenly changed.
Endvidere er det fra tysk fremlæggelsesskrift nr. 2.161.745 kendt i området ved enden af en tærskekurv ud i ét at påhæng-25 sle en skråstiver, hvis anden ende bliver ført forskydeligt, og som en fjeder angriber på, så at optrædende belastningssvingninger på tærskekurven kan blive udlignet.Furthermore, from German Patent Specification No. 2,161,745, it is known in the area at the end of a threshing basket to integrate one slanting strut, the other end of which is slidably slid, and which a spring attacks on, so that load fluctuations occur on the threshing basket. can be equalized.
Fra tysk patentskrift nr. 84.358 kendes en mejetærsker af 30 den i indledningen angivne art, som har en tærskekurv, der består af to med hinanden ledforbundne tærskekurvsegmenter, som er således udformet, at hvert af et fremmedlegeme tilbagetrængt led skal trykke hele tærskekurven bort fra cylinderen. Omstillingen af de enkelte relativt store segmentagtige 35 tærskekurvdele opviser dog den store ulempe, at ved optræd- ning af forhindringer sker der ikke straks en indstilling af de enkelte tærskekurvsegmenter, da disse som følge af deres 2German Patent No. 84,358 discloses a combine of the kind specified in the preamble, which has a threshing basket consisting of two interconnected threshing segments, which are designed so that each of a foreign body retracted joint must push the entire threshing basket away from the cylinder. . However, the conversion of the individual relatively large segment-like 35 threshing basket parts shows the great disadvantage that when obstacles occur, the individual threshing basket segments are not immediately adjusted, as these due to their 2

store masse arbejder meget tungt og derfor ikke er lette at indstille. En indstilling bliver vanskeliggjort af den relativt materialeforbrugende og komplicerede lejring af tærskekurv-segmenterne. Af denne grund er den relativt dyre og materiale-5 forbrugende udformning af en tærskekurv med flere led i praksis uden betydning.large mass works very heavy and therefore is not easy to adjust. An adjustment is made more difficult by the relatively material-consuming and complicated storage of the threshing basket segments. For this reason, the relatively expensive and material-consuming design of a multi-joint threshing basket is of no importance in practice.
I forhold til dette er formålet med opfindelsen at udforme og anbringe mindst ét tærskekurvsegment, således at der i afhængighed af korngennemgangen altid kan blive dannet en optimal spaltebredde mellem tærskekurven og tærskecylinderen. Dette formål bliver opnået ved, at det nedstrøms liggende tærskekurvsegment har et buemål, som er mindre end buemålet for det opstrøms liggende tærskekurvsegment og derved omfatter en flade på mellem 10% og 40% af tærskekurvens samlede flade, hvorved det nedstrøms liggende tærskekurvsegment via fjederen støtter sig på rammen, der sammen med det opstrøms liggende tærskekurvsegment kan drejes ved hjælp af den yderligere indstillingsindretning. Ved den fordelagtige udformning af tærske- 2 0 kurven bliver imidlertid opnået en let og meget hurtig tilpasning af tærskekurvens udløbsende, da ikke mere tærskekurvens samlede ramme, men kun tærskekurvsegmentet forskyder sig i forhold til rammen. Spaltebredden for den samlede tærskekurv kan derudover uden videre yderligere indstilles ved hjælp 2 5 af en indstillingsindretning, hvorved det indstilleligt lejrede tærskekurvsegment bliver medindstillet. På denne måde kan en upåklagelig tilpasning af tærskekurven til forskellige arbejdsbetingelser foretages.In relation to this, the object of the invention is to design and position at least one threshing basket segment so that, depending on the grain passage, an optimal gap width can always be formed between the threshing curve and the threshing cylinder. This object is achieved in that the downstream threshing segment has an arc target which is smaller than the arching dimension of the upstream threshing segment, and thus comprises a surface of between 10% and 40% of the total threshing segment, thereby supporting the downstream threshing segment through the spring. on the frame, which, together with the upstream threshing basket segment, can be rotated by the additional adjusting device. However, in the advantageous design of the threshing curve, an easy and very fast adaptation of the threshing end of the threshing curve is achieved, since no longer the overall frame of the threshing curve, but only the threshing curve segment is displaced relative to the frame. In addition, the gap width of the overall threshing basket can be further adjusted by means of a setting device whereby the adjustably stored threshing segment is co-adjusted. In this way, an impeccable adjustment of the threshing curve to different working conditions can be made.

Hertil er det fordelagtigt, at indstillingsorganet for det nedstrøms liggende tærskekurvsegment ved dets ene ende er hængselforbundet med tærskekurvsegmentet og ved dets anden ende er forskydeligt lejret i den ved tærskekurven eller ved dennes ramme anbragte holder imod virkningen af fjederen, 3 5 o som er anbragt pa indstillingsorganet mellem holderen og en på indstillingsorganet anbragt indstillingsmøtrik. Herved opnår man med relativt enkle midler en enkel indstillings-To this end, it is advantageous that the adjusting means for the downstream threshing segment at its one end is hingedly connected to the threshing segment and at its other end is slidably mounted in the holder positioned by the threshing basket or frame against the action of the spring, which is arranged on the spring. the adjusting means between the holder and a setting nut placed on the adjusting means. In this way, with a relatively simple means a simple adjustment

3 mulighed for taerskekurvsegmentet i området ved tærskekurvens udløbsende. Med henblik på at ændre indstillingsdorganets justerkraft er det fordelagtigt, at indstillingsorganet ved hjælp af en anden indstillingsmøtrik er sikret imod udglidning 5 af holderen og har et mellem holderen og indstillingsmøtrikken anbragt dæmpnings led, og at der til dæmpning af taerskekurvsegmentet findes en trykbeholder, som virker mellem taerskekurvsegmentet og holderen. Ved anvendelsen af dæmpningsleddet kan beskadigelser på tærskekurven i vid udstrækning undgås.3 provides the possibility of the threshing segment in the area at the threshing end. In order to change the adjusting force of the adjusting member, it is advantageous that the adjusting means is secured by means of another adjusting nut against sliding 5 of the holder and has a damping joint located between the holder and the adjusting nut and that a damping vessel exists for damping the drying basket segment. between the dry basket segment and the holder. By using the damping link, damage to the threshing basket can be largely avoided.

Ved en anden udformning af opfindelsen er det fordelagtigt, at der ved de to sidekanter af det nedstrøms liggende tærske-kurvsegment er anbragt en drejelig rammedel, som med rammen hørende til det opstrøms liggende tærskekurvsegment danner 15 et cirkelbueafsnit. Endvidere er det fordelagtigt, at side kanterne for det nedstrøms liggende tærskekurvsegment med rammedelen danner en nedad åben, i tværsnit U-formet optagningsdel, som tjener til optagning af en bærearm, som er anbragt på det opstrøms liggende tærskekurvsegment. Desuden er det 20 fordelagtigt, at bærearmen er stift forbundet med tærskekurv- segmentets ramme, og at fjederen ved dens ene ende afstøtter sig imod bærearmen og ved dens anden ende imod det nedstrøms liggende tærskekurvsegments afgivningsende.In another embodiment of the invention, it is advantageous that at the two side edges of the downstream threshing basket segment a pivotal frame member is provided which, with the frame belonging to the upstream threshing segment, forms a circular arc section. Further, it is advantageous that the side edges of the downstream threshing segment with the frame portion form a downwardly open, cross-sectional U-shaped receiving portion which serves to receive a support arm disposed on the upstream threshing segment. In addition, it is advantageous that the support arm is rigidly connected to the frame of the threshing basket segment and that the spring at one end of it rests against the support arm and at its other end against the delivery end of the downstream threshing segment.
25 Ved hjælp af tegningen bliver der i det følgende beskrevet et udførelseseksempel for et apparat ifølge opfindelsen til ændring af afstanden mellem tærskecylinderen og tærsketromlen i en mejetærsker, hvor 30 fig. 1 viser et sidebillede af en tærskecylinder og en tærske- kurv for en mejetærsker ifølge opfindelsen med tilhørende indstillingsindretning og fig. 2 perspektivisk den højre udløbsende for et tærskekurv-35 segment med den tilhørende indstillingsindretning.With the aid of the drawing, an embodiment of an apparatus according to the invention is described below for changing the distance between the threshing cylinder and the threshing drum in a combine, wherein FIG. 1 is a side view of a threshing cylinder and a threshing basket for a combine harvester according to the invention with associated adjusting device; and FIG. 2 is a perspective view of the right outlet end of a threshing basket segment with its adjusting device.

På tegningen er med 10 betegnet en tærskecylinder, som· er drejeligt lejret på en aksel 12, der er lejret i sidevægge hørende til en på tegningen ikke vist mejetærsker. Tærske-cylinderen 10 består af flere parallelt med hinanden forlø-5 bende, på akselen 12 anbragte tærskekurvskiver 14, som ved hjælp af talrige tærskestokke 16 er forbundet med hinanden. Tærskecylinderen 10 bliver ved hjælp af en på tegningen ikke vist drivanordning ifølge pilen 17 drevet imod urviserens retning.In the drawing, a threshing cylinder is indicated by 10, which is rotatably mounted on a shaft 12, which is mounted in sidewalls belonging to a combine harvester not shown in the drawing. The threshing cylinder 10 consists of a plurality of parallel running parallel to the threshing discs 14 arranged on the shaft 12, which are connected to each other by means of numerous threshing sticks 16. The threshing cylinder 10 is driven by a drive device not shown in the drawing, according to the arrow 17, in the direction of the clockwise direction.

Neden under tærskecylinderen 10 befinder sig en tærskekurv 18, som i området ved sin modtagelsesside 20 er lejret drejeligt på en aksel 22. Akselen 22 kan være optaget i en på tegningen ikke vist holder eller i mejetærskerens sidevægge.Below the threshing cylinder 10 is a threshing basket 18, which in the region at its receiving side 20 is pivotally mounted on a shaft 22. The shaft 22 may be accommodated in a holder not shown in the drawing or in the sidewalls of the combine.
15 Tærskekurven 18 omslutter omtrent 90% af den nedre del af tærskecylinderen, der er udformet som en tærskecylinder for en tværstrøms mejetærsker med en hylderyster. Skulle tærskecylinderen 10 benyttes til en aksialstrømsmejetærsker, så må en cylindrisk beholderkappe slutte sig til tærskekurven, 20 så at tærskekurven og beholderkappen fuldstændigt omslutter tærskecylinderen.The threshing curve 18 encloses about 90% of the lower portion of the threshing cylinder, which is designed as a threshing cylinder for a cross-flow combine with a shelf shaker. If the threshing cylinder 10 is used for an axial flow combine, a cylindrical container sheath must join the threshing curve, so that the threshing curve and the container sheath completely enclose the threshing cylinder.
Som det fremgår af fig. 2, består tærskekurven af talrige i afstand fra hinanden anbragte, i omløbsretningen halvcirkel-25 formet buede kurvtråde eller ribber 24, som er indbyrdes for bundne ved hjælp af talrige parallelle og tværgående sprosser 26. De enkelte sprosser 26 er ved hver ende lejret i en ramme 28, der er en del af tærskekurven 18.As shown in FIG. 2, the threshing basket consists of numerous spaced apart spaced, semicircular curved wires or ribs 24 which are interconnected by means of numerous parallel and transverse bars 26. The individual bars 26 are located at each end in a frame 28 which is part of the threshing basket 18.

Som det især fremgår af fig. 1, består tærskekurven 18 af to tærskekurvsegmenter 30 og 32 med forskellig størrelse.As can be seen in particular from FIG. 1, the threshing basket 18 consists of two threshing basket segments 30 and 32 of different sizes.
Det opstrøms liggende tærskekurvsegment 30 er væsentligt større end det nedstrøms liggende tærskekurvsegment 32. Det opstrøms liggende tærskekurvsegment 30 kan have en buelængde, som mak- -s g 0 simalt er tre gange så stor som buelængden for det nedstrøms liggende tærskekurvsegment 32. Tærskekurvsegmentet 32 ligger med sin indre cirkelbueformede overflade på en cylinder medThe upstream threshing segment 30 is substantially larger than the downstream threshing segment 32. The upstream threshing segment 30 may have an arc length which is at most three times as large as the arc length of the downstream threshing segment 32. its inner circular arcuate surface on a cylinder with

5 samme radius som det opstrøms liggende tærskekurvsegment 30. Tasrskekurvsegmentet 32 er ligesom den tidligere beskrevne tærskekurv 18 dannet af talrige indbyrdes parallelt forløbende ikke viste ribber, som ligeledes ved hjælp af de tværgående 5 sprosser 26 bliver forbundet med hinanden. Tærskekurvsegmentet 32 bliver i begge sider begrænset af en ramme 34, hvor i fig.5, the same radius as the upstream threshing segment 30. The threshing segment 32, like the previously described threshing 18, is formed by numerous mutually unrelated ribs which are also connected to each other by means of the transverse thrusters 26. The threshing basket segment 32 is limited on both sides by a frame 34, where in FIG.
2 kun den i forhold til bevægelsesretningen for kornet højre rammedel er vist. Rammen 34 består af et nedad åbent u-formet buestykke, som ved hjælp af en bolt 36 er drejeligt forbundet 1° med den tilhørende ramme 28 af det opstrøms liggende tærskekurv segment 30. I området ved tærskekurvsegmentets 30 afgivningsende er tærskekurvsegmentet 30 forsynet med en som en forlængelse udformet bærearm 38, der er en del af den tilhørende ramme 28. De to over for hinanden liggende bærearme 38 er, 15 som det fremgår af fig. 2, forbundet med hinanden ved hjælp af et tværgående rør 40. Ved de ydre ender af hver bærearm 38 er der tilsluttet en indstillingsindretning 42, som består af en øjeskrue 44 med en på denne indskudt fjeder 46. Øjeskruen 44 er ved sin øvre ende drejeligt forbundet med en med rammen 2° 34 forbundet charnierbolt 48 og med sin nederste ende forskyde ligt optaget i en i bærearmen 38 anbragt holder 50 og ved hjælp af en møtrik 52 sikret mod udglidning. Den på øjeskruen 44 anbragte fjeder 46 afstøtter sig med sin nedre ende mod holderen 50 og med sin øvre ende mod en anslagsskive 54, som 25 ved hjælp af en yderligere på øjeskruen påskruet møtrik 56 kan indstilles med henblik på at ændre forspændingskraften i fjederen 46 på passende måde.2 only the relative direction of movement of the grained right frame portion is shown. The frame 34 consists of a downwardly open u-shaped arc, which is rotatably connected 1 ° to the associated frame 28 of the upstream threshing segment segment by means of a bolt 36. In the region at the discharge end of the threshing segment 30, the threshing segment 30 is provided with a an extension formed support arm 38 which is part of the associated frame 28. The two opposite support arms 38 are, as shown in FIG. 2, connected to each other by a transverse tube 40. At the outer ends of each support arm 38, there is connected an adjusting device 42, consisting of an eye screw 44 with a spring 46 inserted therein. The eye screw 44 is rotatable at its upper end. connected to a carnier bolt 48 connected to the frame 2 34 and with its lower end displaceably accommodated in a holder 50 disposed in the carrier arm 38 and by means of a nut 52 secured against slipping. The spring 46 mounted on the eye screw 44 rests with its lower end against the holder 50 and with its upper end against a stop disk 54, which 25 can be adjusted by means of an additional nut 56 screwed onto the eye screw to change the biasing force of the spring 46 of appropriate way.
Som det fremgår af fig. 1, angriber på den ydre ende af bære-30 armen 38 en yderligere indstillingsindretning 62, som består af en stang 64, der ved den ene ende er hængselforbundet med bærearmen 38 og ved den anden ende med en vægtarm 66, der kan drives ved hjælp af en på tegningen ikke vist indstillingsmotor. Det er dog også muligt tilsvarende at dreje vægtarmen 35 66 ved hjælp af et håndsving.As shown in FIG. 1, on the outer end of the carrier arm 38 attacks a further adjusting device 62 which consists of a rod 64 hinged at one end to the support arm 38 and at the other end to a weight arm 66 operable by means of of a setting motor not shown in the drawing. However, it is also possible to rotate the weight arm 35 66 by means of a crank.
