Description

-1 - DK 176115 B1-1 - DK 176115 B1

Opfindelsen angår en selvkørende høstmaskine, eksempelvis mejetærsker, hvis grundramme for størstedelen er dækket af sidevægge, hvorved der l det mindste i én sidevægs område er anbragt en potteformet sigtecylinder udsvin-geligt omkring en fast aksel, igennem hvilken cylinder den til køling af ek-s sempelvis drivmotoren nødvendige luft suges ind ved hjælp af en propel.The invention relates to a self-propelled harvester, for example combine harvesters, the basic frame of which is for the most part covered by sidewalls, whereby at least in one sidewall area a pot-shaped sieve cylinder is arranged pivotally around a fixed shaft, through which the cylinder for cooling the for example, the required air motor is sucked in with a propeller.

„ En sådan høstmaskine kendes eksempelvis fra DE-offentliggørelsesskrift 2430307. Fig. 3 i dette offentliggørelsesskrift viser sigtecylinderen i udsvunget stilling, for at man kan udføre nødvendige vedligeholdelsesarbejder. Svingakslen, som sigtecylinderen er svunget ud omkring, forløber derved vertikalt, to således at sigtecylinderen i udsvunget stilling rager langt frem foran mejetærskerens sidevæg med sin yderste ende. En sådan svingbevægelse forudsætter, at der eksempelvis i den hal, som en mejetærsker står i, findes tilstrækkelig sideafstand til halvæggen eller til et andet køretøj, som er parkeret i hallen."Such an harvesting machine is known, for example, from DE Publication No. 2430307. FIG. 3 of this publication, the sieve cylinder is shown in the oscillating position in order to carry out necessary maintenance work. The pivot shaft around which the sieve cylinder is pivoted extends thereby vertically, two so that the sieve cylinder projects in a swung position far ahead of the side wall of the combine with its outer end. Such a swivel movement assumes, for example, that in the hall in which a combine is standing, there is sufficient lateral distance to the half-wall or to another vehicle parked in the hall.

Til grund for den foreliggende opfindelse ligger der det problem at udforis me en mejetærsker af den Indledningsvis nærmere betegnede type således, at det er muligt at flytte det roterende luftrenserianlæg på snæver plads med henblik på vedligeholdelsesformål.The basis of the present invention lies in the problem of designing a combine of the Initially Specified type so that it is possible to move the rotary air purifier system in narrow space for maintenance purposes.

Dette problem løses ved, at sigtecylinderens svingaksel forløber horisontalt og på tværs af mejetærskerlængdeaksen. På grund af denne position af 2o svingakslen svinges sigtecylinderen nu opad i en vedligeholdelsesposition, hvor den eksempelvis stillingsfikseres ved hjælp af en i og for sig kendt gasfjeder. I denne udsvungne position udgør sigtecylinderen hverken en fare for kvæstelse af betjeningspersonen, eller det er nødvendigt med yderligere afstand til siden.This problem is solved by the swivel axis of the sieve cylinder extending horizontally and across the combine longitudinal axis. Because of this position of the 2o pivot shaft, the sieve cylinder is now pivoted upwards in a maintenance position, where it is, for example, fixed by means of a gas spring known per se. In this swung position, the aiming cylinder does not pose any danger to the operator or further distance to the side is required.

2s Yderligere fordelagtige udførelsesformer er defineret nærmere i uselv stændige krav.2s Further advantageous embodiments are further defined in the claims of the present invention.

I det følgende skal opfindelsen forklares nærmere ved hjælp af et udførelseseksempel og flere figurer, som viser dette skematisk. På tegningen viser: 3o fig. 1 den forreste del af en mejetærsker i perspektivtegning, fig. 2 den på fig. 1 viste sigtecylinder i perspektiv med tilhørende monteringsramme, fig. 3 den på fig. 2 viste sigtecylinder set forfra og fig. 4 et snit igennem den på fig. 3 viste sigtecylinder.In the following, the invention will be explained in more detail by means of an exemplary embodiment and several figures which show this schematically. In the drawing: FIG. 1 is a perspective view of the front portion of a combine harvester; FIG. 2 is the one shown in FIG. 1 is a perspective view of the sieve cylinder with associated mounting frame; FIG. 3 shows the one shown in FIG. 2 is a front view of the sieve cylinder and FIG. 4 is a section through the embodiment of FIG. 3.

Med 1 er der betegnet en i og for sig kendt selvkørende mejetærsker med drevne forhjul 2 og bageste styrehjul 3. Til siden er mejetærskeren 1 dækket af 35 - 2 - DK 176115 B1 vægge, af hvilke kun væggen 4 er synlig på fig. 1. En del af sidevæggen 4 har en udsparing 5.By 1 is denoted a known self-propelled combine with driven front wheels 2 and rear steering wheel 3. Next, the combine 1 is covered by 35 - 2 - DK walls of which only the wall 4 is visible in FIG. 1. A portion of the sidewall 4 has a recess 5.

I dette område er der med mejetærskerens hovedramme indsat et ramme-hus 6, hvis forreste åbning 7 kan lukkes med en svingbar dør 8. Det bliver s tydeligt på fig. 4, at der l rammehuset 6 er indsat en radiator 9 og en køler 10, igennem hvilke der ved hjælp af en kun skematisk vist propel 11 suges luft ind udefra, som skal køles, og som på kendt måde tjener til køling af drivmotoren.In this area, a frame housing 6 is inserted with the main frame of the combine, the front opening 7 of which can be closed with a pivotable door 8. As can be seen in FIG. 4, a radiator 9 and a cooler 10 are inserted into the frame housing 6, through which, by means of only a schematically shown propeller 11, air is sucked in from outside, which is to be cooled and which in a known manner serves to cool the drive motor.

For at denne indsugne luft skal være fri for urenheder, er der anbragt en potteagtig sigtecylinder 12. Sidstnævnte er lejret drejeligt omkring den faste mid-io teraksel 13. Til dette formål er der på akslen 13 påsat lejer 14 og 15, hvorved lejet 14 er forbundet med sigtecylinderens 12 forvæg 16 og lejet 15 med sigte-cylinderens 12 cylinderkappe 18 via arme 17. Akslen 13 er i den ene ende svejset fast sammen med stivere 19, som med deres fra akslen 13 bortvendte ender er fast forbundet med døren 8. Døren 8 har en cirkelrund åbning 20, som er lukket is tætnende med den cirkelrunde sigtecylinder 12. Sigtecylinderen 12 trækkes via en rem 21 (se fig. 3), hvorved remmen 21 omslutter et drivhjul 22, som er forbundet med en fast koblingsdel 23 (se fig. 4). Koblingsdelen 24 slutter fast op mod denne koblingsdel 23 i svunget tilstand ved hjælp af fjederens 25 kraft. Koblingsdelen 24 samt fjederen 25 sidder på en drivbar aksel 26, hvorved fje-2o deren 25 i den ene ende slutter op mod en fast med akslen 26 forbundet ansats 27. Det bliver tydeligt på fig. 2 og 3, at henholdsvis sigtecylinderen 12 og døren 8 i løftet tilstand sikres ved hjælp af en gasfjeder 28 i udsvunget stilling. Ud-svingningen sker derved omkring en svingaksel 29, som er forbundet med rammehuset 6. Til dette formål er en arm 30, som har en lejeboring 31, fast for-2s bundet med døren 8. En ende af svingakslen 29 rager igennem denne leje-boring, hvorved armen 30 er sikret mod aksial forskydning på svingakslen 29 eksempelvis med fjederringe. Det bliver tydeligt på Fig. 1, at døren 8 er forskudt så langt indad i forhold til mejetærskerens sidevæg 4, at sigtecylinderens 12 forvæg eller 12 bund 12’ omtrent forløber I et plan med sidevæggen 4. jo Herved fremkommer der ikke kun et formskønt ydre udseende, men her ved formindskes også faren for kvæstelser 1 driftstilstand betydeligt.In order for this aspirated air to be free of impurities, a pot-like sieve cylinder 12 is provided. The latter is mounted pivotally around the solid mid-shaft 13. For this purpose, bearings 14 and 15 are mounted on shaft 13, whereby the bearing 14 is connected to the front wall 16 of the sieve cylinder 12 and the bearing 15 to the sealing cylinder 18 of the sieve cylinder 12 via arms 17. The shaft 13 is welded at one end together with struts 19, which with their ends facing away from the shaft 13 are firmly connected to the door 8. The door 8 has a circular opening 20 which is sealed in ice sealing with the circular sieve cylinder 12. The sieve cylinder 12 is pulled via a belt 21 (see FIG. 3), whereby the belt 21 encloses a drive wheel 22 which is connected to a fixed coupling part 23 (see Fig. 4). The coupling part 24 is firmly connected to this coupling part 23 in the pivoted state by the force of the spring 25. The coupling part 24 and the spring 25 are mounted on a drive shaft 26, whereby the spring 25 at one end ends up against a fixed shaft 27. It is evident in FIG. 2 and 3, respectively, that the sieve cylinder 12 and the door 8 are secured in the raised state by means of a gas spring 28 in the swung position. The oscillation thus takes place around a pivot shaft 29 which is connected to the frame housing 6. For this purpose, an arm 30 having a bearing bore 31 is fixedly connected to the door 8. An end of the pivot shaft 29 projects through this bearing housing. bore, whereby the arm 30 is secured against axial displacement on the pivot shaft 29, for example with spring rings. It becomes clear from FIG. 1, that the door 8 is displaced so far inward from the sidewall 4 of the combine that the front wall or bottom 12 of the screen cylinder 12 extends approximately in a plane with the sidewall 4. Thus, not only does a beautiful external appearance appear, but here by diminishing also the danger of injuries 1 operating state significantly.

For at kunne fiksere døren 8 med den roterende sigtecylinder 12 1 indsvunget driftsstilling er der forbundet tapper 31 og 32 fast med døren 8 på dens indvendige side. På tappen 31 er der lejret et håndtag 33 drejeligt, som både en 35 indvendig klinke 34 og et forlængerstykke 35 er fast forbundet med. Det fremgår af fig. 3, at klinken 34 i indsvunget tilstand griber Ind i fallen 36. En yderligere klinke 37 griber ind i fallen 38, hvorved begge faller 36 og 38 er svejset - 3 - DK 176115 B1 fast sammen med rammehuset 6. Klinken 37 er lejret drejeligt på tappen 32, hvorved klinken 37 har en forlængelse 40. Denne forlængelse 40 og håndtagets 33 forlængelse 35 står i forbindelse med hinanden via en stang 41, således at både klinken 34 og klinken 37 kan bevæges i låsestilling og ud af låsestillingen s ved betjening af håndtaget 33.In order to be able to fix the door 8 with the rotating sieve cylinder 12 in the pivoted operating position, pins 31 and 32 are connected firmly to the door 8 on its inner side. On the pin 31, a handle 33 is pivotally mounted, to which both an inner latch 34 and an extension piece 35 are firmly connected. It can be seen from FIG. 3, that the latch 34 engages in the case 36 in a flung-in condition. A further latch 37 engages in the case 38, whereby both falls 36 and 38 are welded together with the frame housing 6. The latch 37 is mounted rotatably on the pin 32, whereby the latch 37 has an extension 40. This extension 40 and the extension 35 of the handle 33 communicate with each other via a rod 41, so that both the latch 34 and the latch 37 can be moved in the locking position and out of the locking position s when operating the handle. 33rd
