Opfindelsen angår en mejetærsker med en ved en halmnedfaldshætte fast anbragt hakkelsesmaskine, hvis knivrotor efter ønske kan overdækkes med en halmledeklap, som er svingelig om en nedre på et hus for hakkelsesmaskinen lejret drejningsakse, og hvor hakkelsesmaskinen ind-5 og udkobleligt drives ved hjælp af kileremme og remskiver.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a combine harvester with a chopper machine fixedly attached to a straw fall cap, the blade rotor of which can be covered, if desired, with a straw guide flap which is pivotable about a lower axis of a rotary shaft mounted on the chopping machine and the chopping machine can be switched on and disengaged by and pulleys.

Det er allerede kendt at forsyne mejetærskere med hakkelsesmaskiner, som sønderdeler den tærskede halm, inden den falder ned på marken, så at den derefter let kan nedpløjes. For at tilvejebringe mulighed for at udkaste halmen hakket eller ikke hakket er der også allerede frem-10 kommet mejetærskere, ved hvilke den under halmnedfaidsskakten anbragte hakkelsesmaskine kan svinges bort fra halmnedfaldsskaktens nedadrettede åbning i retning fremad eller bagud. Da hakkelsesmaskinen er et forholdsvis tungt aggregat og desuden behøver en drivforbindelse med mejetærskeren, betyder den svingelige anordning af hakkelsesmaskinen et 15 kostbart teknisk opbud, og en omstilling af mejetærskeren fra drift med hakkelsesmaskine til drift uden hakkelsesmaskine eller omvendt kræver et ikke uvæsentligt kraft- og tidsforbrug. Til undgåelse af disse ulemper er der fremkommet en mejetærsker med indbygget hakkelsesmaskine, der muliggør en omstilling fra drift med hakkelsesmaskine til drift u-20 den hakkelsesmaskine eller omvendt uden ændring af hakkelsesmaskinens stilling i mejetærskeren. X dette øjemed er der anbragt en halmledeklap, som er svingelig omkring en på hakkelsesmaskinehuset anbragt akse, således at den i den ene stilling overdækker en i den såkaldte halmhætte på mejetærskerhuset udformet halmnedfaldsåbning og i den an-25 den svingningsstilling overdækker indløbsåbningen til den fast på halmhætten monterede hakkelsesmaskine. Hakkelsesmaskinen er altså fast monteret på halmhætten og forbliver ved enhver driftsmåde i denne fast monterede stilling. Til omstilling til drift med eller uden hakkelsesmaskine svinges halmledeklappen tilsvarende med enkle midler og uden 30 stort kraftopbud, så at den fra mejetærskerens rystere nedfaldne halm kommer ind i hakkelsesmaskinens indløbsåbning eller aflægges i et skår på marken. Hvis man imidlertid glemmer samtidig med svingningen af halmledepladen at ind- eller udkoble hakkelsesmaskinens drivmekanisme, opstår der ved halmtilførsel og udkoblet hakkelsesmaskine forstoppelse 35 i mejetærskerens rysterum, eller omvendt kolliderer de roterende knive - 2 - 149421 med halmledepladen.It is already known to provide combine harvesters with chopping machines, which disintegrate the threshing straw before falling into the field, so that it can then be easily plowed. In order to provide the possibility of ejecting the straw chopped or not chopped, combine harvesters have also already been provided, in which the chopping machine placed under the straw chute can be pivoted away from the downward opening of the straw chute in the forward or backward direction. Since the chopping machine is a relatively heavy aggregate and furthermore requires a drive connection with the combine, the swiveling device of the chopping machine means a costly technical offering, and a conversion of the combine from operation with a chopping machine to operating without a chopping machine or vice versa requires no significant power and time consumption. . To avoid these drawbacks, a built-in chopper combine has been provided which allows a switch from operation with the chopping machine to operation without the chopping machine or vice versa without changing the position of the chopping machine in the combine. For this purpose, a straw hinge flap is pivotally arranged about an axis disposed on the chopping machine housing, so that in one position it covers a straw drop opening formed in the so-called straw cap on the combine and in the other swing position it covers the inlet opening. the straw cap mounted chopping machine. The chopping machine is thus firmly mounted on the straw cap and remains in every operating mode in this fixed position. For conversion to operation with or without chopping machine, the straw guide flap is swiveled correspondingly with simple means and without a large power supply, so that it falls from the shredder's shredder straw into the chopping machine's inlet opening or is deposited in a groove in the field. However, if at the same time as the swing of the straw baffle is forgotten to enable or disengage the chopping machine's drive mechanism, by straw supply and cut-off chopper machine constipation 35 occurs in the combine's shaking room, or vice versa, the rotating blades - 2 - 149421 collide with the straw baffle.

Den foreliggende opfindelse har derfor til opgave at tilvejebringe en mejetærsker af den indledningsvis angivne art, ved hvilken halralede-klappens svingningsbevægelse udnyttes dels til forhindring af maskin-5 skader, dels til tilvejebringelse af hakkelsesmaskinens driftsberedskab. Dette opnås ifølge opfindelsen ved, at en første drevet remskive er fast forbundet med hakkelsesmaskinens rotoraksel, at der løst på denne aksel ved siden af den første remskive er anbragt en anden remskive, hvortil drivremmen kan overføres, at der på hakkelsesmaskinen er 10 anbragt et med halmledeklappen koblet drejeligt første spærreorgan, som, når drivremmen befinder sig på remskiven, ved svingning støder mod den løse remskives spor og derved forhindrer halmledeklappen i at dreje til en stilling, ved hvilken halmmaterialet føres uden om hakkelsesmaskinen og/eller at der på hakkelsesmaskinen er anbragt et med halmlede-15 klappen koblet drejeligt andet spærreorgan, som, når drivremmen befinder sig på den løse remskive, støder mod den fast forbundne skives spor og derved forhindrer halmledeklappen i at dreje til en stilling, ved hvilken halmmaterialet føres til hakkelsesmaskinen.It is therefore the object of the present invention to provide a combine of the kind set forth at the outset, in which the oscillating movement of the tailgate flap is utilized partly to prevent machine damage and partly to provide the chopping machine's operational readiness. This is achieved according to the invention in that a first driven pulley is fixedly connected to the rotor shaft of the chopping machine, that a second pulley is mounted on the shaft next to the first pulley, to which the drive belt can be transferred, that one with the chopping machine the straw guide flap is pivotally coupled to the first locking means which, when the drive belt is on the pulley, abuts against the track of the loose pulley, thereby preventing the straw guide flap from rotating to a position at which the straw material is passed around the chopping machine and / or that the chopping machine is placed a rotatable second locking means coupled to the straw guide flap which, when the drive belt is on the loose pulley, abuts the track of the fixed disc and thereby prevents the straw guide flap from turning to a position at which the straw material is fed to the chopping machine.

Ved hjælp af den foreliggende opfindelse bliver altså mejetærsker-20 køreren ved hjælp af de i remskiverne indgribende segmenter stadig informeret om, hvorvidt hakkelsesmaskinen ved tilsvarende stilling af halmledeklappen også faktisk er ind- eller udkoblet.Thus, by means of the present invention, the combine harvester driver is still informed by means of the segments engaging the pulleys whether the chopping machine is also switched on or off at the corresponding position of the straw guide flap.

Opfindelsen er nærmere forklaret i det følgende under henvisning til tegningen, på hvilken 25 fig. 1 viser en mejetærsker med indbygget hakkelsesmaskine, fig. 2 i større målestok den i fig. 1 viste indbyggede hakkelsesmaskine, set fra siden og tildels fra oven, og fig. 3 den i fig. 2 viste indbyggede hakkelsesmaskine med bortsvinget halmledeklap, ligeledes set fra siden og delvis 30 fra oven.The invention is further explained in the following with reference to the drawing, in which FIG. 1 shows a combine harvester with built-in chopping machine; FIG. 2 on a larger scale, the one shown in FIG. 1 is a side view, partly from above, of the built-in chopping machine; and FIG. 3 shows the one shown in FIG. 2 incorporates a chopped straw flap flap, also viewed from the side and partially 30 from above.

På tegningen betegner 1 en selvkørende mejetærsker, hvis halmhætte 2 har en nedfaldsåbning 3. I denne nedfaldsåbning 3 er fast anbragt en hakkelsesmaskine 4. Hakkeknivakslen 5 i denne hakkelsesmaskine 4 rager ud fra siden af halmhætten 2*s hus og bærer på denne udragende ende bå-35 de en med hakkeknivakslen 5 fast forbundet kileremskive 6 og en på ak- - 3 - U942t sien frit drejelig kileremskive 7. 1 den i fig. 2 viste stilling er der lagt en kilerem 8 på den med akslen fast forbundne kileremskive 6, så at hakkeknivakslen 5 drives. Kileremmen 8 er, som vist i fig. 1, ført omkring en yderligere drivende skive 9 og holdes ved hjælp af en rulle 5 10 mider spænding. I denne arbejdsstilling af hakkelsesmaskinen 4 er den på to tappe 16 lejrede halmledeklap 11 ved hjælp af ikke viste midler svinget over mod halmhætten 2's bagvæg 12, så at den fra rysterne 13 afkastede, af tærskede halm kommer ind i hakkelsesmaskinen 4 og falder i sønderdelt tilstand ned på marken. For nu at sikre, at kileremmen 10 8 også faktisk er lagt på den rigtige kileremskive 6, således at der ved den i fig. 2 viste stilling af halmledeklappen undgås forstoppelser i mejetærskerens rysterum, er der på tappen 16 påsvejset et segment 14 på en sådan måde, at det griber ind i den på hakkeknivakslen 5 løst påsatte kileremskive 7. Dette er imidlertid kun muligt, hvis rammen 8 er 15 lagt på den med akslen 5 fast forbundne skive 6. Ellers ville nemlig segmentet 14 støde mod den urigtigt på skiven 7 pålagte rem 8 og dermed forhindre halmledeklappen 11's svingningsbevægelse. I fig. 3 er et segment 14' anbragt således forsat i forhold til den i fig. 2 viste stilling, at det ved overdækket hakkelsesmaskine og åben nedfaldsåbning 3 20 griber ind i den med akslen 5 fast forbundne skive 6. Derved forhindres med sikkerhed, at hakkeknivakslen 5 drives, når hakkelsesmaskinen 4 er overdækket af halmledeklappen 11, således at beskadigelser af halmledeklappen 11 på grund af roterende knive 15 forhindres. Naturligvis er det muligt, og dette fremgår af fig. 2, at forbinde to segmenter 14 og 25 14' fast med tappen 16 og forsætte dem indbyrdes således, at der i hver af halmledeklappen 11's to mulige endestillinger griber et segment 14 eller 14' ind i den tilsvarende kileremskive 7 eller 6.In the drawing, 1 denotes a self-propelled combine harvester whose straw cap 2 has a fallout opening 3. In this fallout opening 3 is fixed a chopping machine 4. The chopping knife shaft 5 of this chopping machine 4 protrudes from the side of the straw cap 2 * s and carries on this protruding end. -35 the V-belt pulley 6 fixedly connected to the cutting knife shaft 5 and a V-belt rotatable 7 on the shaft 3. 2, a V-belt 8 is mounted on the V-belt pulley fixedly connected to the shaft, so that the cutting knife shaft 5 is driven. The V-belt 8 is, as shown in FIG. 1, passed around a further driving disc 9 and held by means of a roller 5 10 mids tension. In this working position of the chopping machine 4, the straw guide flap 11, which is mounted on two pins 16, is pivoted by means not shown against the back wall 12 of the straw cap 2, so that it returns from the shakes 13 of threshing straw into the chopping machine 4 and falls into disintegrated state. down in the field. Now, to ensure that the V-belt 10 8 is also actually mounted on the correct V-belt pulley 6, so that in the case shown in FIG. 2, when the position of the straw hinge flap is prevented from constipation in the shaking chamber of the combine, a segment 14 is welded in such a way that it engages the V-belt pulley 7 loosely mounted on the chopping knife shaft 5. However, this is only possible if the frame 8 is 15 otherwise, the segment 14 would impinge on the belt 8 incorrectly applied to the disc 7 and thus prevent the swinging of the straw guide flap 11. In FIG. 3, a segment 14 'is thus positioned offset from that of FIG. 2 shows that by the covered chopping machine and open fallout opening 3 20 engages the disc fixedly connected to the shaft 5, thereby preventing the chopping knife shaft 5 from being driven when the chopping machine 4 is covered by the straw hinge flap 11, so that damage to the straw hinge flap 11 due to rotating blades 15 is prevented. Of course, this is possible and this can be seen in FIG. 2, to connect two segments 14 and 25 14 'firmly to the pin 16 and move them mutually so that in each of the two possible end positions of a straw guide flap 11, a segment 14 or 14' engages the corresponding V-belt pulley 7 or 6.

Opfindelsen er ikke begrænset til udførelseseksemplet· Således kan halmledeklappens bevægelse i stedet for spærresegmenterne også ad elek-30 trisk, elektromekanisk eller hydraulisk vej aktivere andre komponenter som f.ex. koblinger og ventiler.The invention is not limited to the exemplary embodiment. Thus, instead of the blocking segments, the movement of the straw flap can also activate other components such as, for example, electrically, electromechanically or hydraulically. couplings and valves.
