Opfindelsen vedrører en vendeplov med et pendulstøtte- og efterløbstransporthjul i henhold til indledningen til krav 1.The invention relates to a reversing plow with a shuttle support and post transport wheel according to the preamble of claim 1.

Ved sådanne vendeplove (tysk offentliggørelses-5 skrift nr. 30 33 791), hvor hjulet i vendeplovens arbejdsstillinger tjener som støttehjul og i vendeplovens halvvendte transportstilling -tjener som efterløbende transporthjul, bestemmer lejeorganet for hjulbæreren en enkelt lejeakse, der tjener både som pendulakse og som 10 høj akse. Lejeaksen kan imidlertid ved hjælp af et på plovrammen anbragt hængsel svinges mellem to stillinger og låses i disse. Dette tillader, at hjulbæreren ved plovdrift er nær plovrammen, og at lejeaksen i transportstillingen kan gøres vinkelret på jorden. Denne ind-15 stilling af lejeaksen i transportstillingen undgår bevægelse i højden af vendeploven ved kørsel i kurver og ved rangering.In such reversing plows (German Publication 5 30 33 791), where the wheel in the reversing plow's working positions serves as a supporting wheel and in the reversing plow's semi-reverse transport position serves as a trailing transport wheel, the bearing means for the wheel carrier determines a single bearing axis that serves both as a shaft and as a shaft. 10 high axis. However, the bearing axis can be pivoted between two positions by means of a hinge placed on the plow frame and locked in them. This allows the wheel carrier to be near the plow frame during plow operation and the bearing axis in the transport position can be made perpendicular to the ground. This positioning of the bearing axis in the transport position avoids movement in the height of the reversing plow when driving in curves and when ranking.

Ved denne kendte vendeplov er indstillingsmulighederne imidlertid begrænset, medens på den anden side 20 indstillingen kræver et fremspringende lejeorgan, der til omstillingen kræver en væsentlig betjeningsindsats.However, with this known reversing plow, the adjustment possibilities are limited, while on the other hand the adjustment requires a protruding bearing means which requires a significant operating effort for the adjustment.

Med opfindelsen tilsigtes der tilvejebragt en vendeplov af den i indledningen til krav 1 angivne art, ved hvilken pendulaksen for pløjearbejdsstillingen og 25 høj aksen for transportstillingen kan indstilles uafhængigt af -hinanden, og ved hvilken -der ved en simpel og kompakt udførelsesform for lejeorganet muliggøres en let og hurtig omstilling. Dette opnås ifølge opfindelsen ved hjælp af de i den kendtegnende del af krav l angivne 30 træk. Med hensyn til yderligere udførelsesformer henvises der til krav 2-7.The invention aims at providing a reversing plow of the kind set forth in the preamble of claim 1, in which the pendulum axis for the plow working position and the high axis of the transport position can be adjusted independently of the hand, and in which a simple and compact embodiment of the bearing means is possible. easy and quick conversion. This is achieved according to the invention by means of the features defined in the characterizing part of claim 1. With respect to further embodiments, reference is made to claims 2-7.

Da pendulaksen for pløj edrift og høj aksen for transportdrift bestemmes af separate akser i lejeorganet, er en indbyrdes uafhængig finindstilling af akse-35 retningerne ud fra plovrammens stillinger mulig. Til den valgfri frigivelse af hjulbærerens bevægelighed om den 2Since the pendulum axis for plow operation and the high axis for transport operation is determined by separate axes in the bearing member, an independent fine tuning of the axis directions from the positions of the plow frame is possible. For the optional release of the wheel carrier movement on the 2

ene eller den anden akse er et enkelt håndtag tilstrækkelig. Lejeorganet er samtidig en kompakt, ufølsom og vedligeholdelsesvenlig konstruktionsdel, der samtidig også er simpel at montere.one or the other axis is sufficient for a single handle. The bearing member is at the same time a compact, insensitive and maintenance-friendly construction part, which is also easy to install.

5 To udførelsesformer for vendeploven ifølge opfin delsen beskrives nærmere i det følgende under henvisning til tegningen, hvor fig. 1 viser et delbillede ovenfra af den bageste ende af en vendeplov ifølge opfindelsen i pløjearbejds-10 stilling, fig. 2 et sidebillede af den bageste ende af vendeploven i transportstilling, fig. 3 et snit efter linien Ill-Ill i fig. l, og fig. 4 et snit gennem et lejeorgan i en anden 15 udførelsesform for vendeploven ifølge opfindelsen.Two embodiments of the reversing plow according to the invention are described in more detail below with reference to the drawing, in which: FIG. 1 is a top plan view of the rear end of a reversing plow according to the invention in plow working position; FIG. 2 is a side view of the rear end of the reversing plow in the transport position; FIG. 3 is a sectional view taken along the line III-III in FIG. 1, and FIG. 4 shows a section through a bearing member in another embodiment of the reversing plow according to the invention.

Pig. 1 viser den bageste ende af en plovramme 1, der på sædvanlig måde er forsynet med rækker af plovkroppe 2, der gennem et tilslutningsorgan 3 er forbundet med plovrammen 1. Ved den bageste ende af plov-20 rammen 1 er der påflanget et lejeorgan 4, ved hjælp af hvilket en hjulbærer 5 for et pendulstøtte- og ef-terløbstransporthjul 6 er lejret. Det delvis i snit anskueliggjorte lejeorgan 4 omfatter en ydre lejebøsning 7, der bestemmer en første akse 8, og en i denne 25 lejret mellemlejebøsning 9, der på sin side bestemmer en anden akse 10. I mellemlejebøsningen 9 er hjulbæreren 5 lejret ved hjælp af en tap 11, der stikker vinkelret ud fra en bøsning 12, der bestemmer en svingakse 13 for en del 14 af hjulbæreren 5. Delen 14 30 af hjulbæreren 5 er lejret i bøsningen 12 ved hjælp af en tap 15 og er forsynet med en låseindretning 16, ved hjælp af hvilken delen 14 kan arreteres i sin i fig. 1 viste svingstilling for pløj edrift og i den i fig. 2 viste svingstilling for transportdrift.Pig. 1 shows the rear end of a plow frame 1, which is provided in the usual manner with rows of plow bodies 2 connected through a connecting member 3 to the plow frame 1. At the rear end of the plow frame 1 a bearing means 4 is flanged. by means of which a wheel carrier 5 for a pendulum support and post transport wheel 6 is mounted. The partially illustrated bearing member 4 comprises an outer bearing sleeve 7 which determines a first axis 8 and a middle bearing sleeve 9 enclosed therein, which in turn determines a second axis 10. In the intermediate bearing sleeve 9, the wheel carrier 5 is mounted by means of a pin 11 projecting perpendicularly from a bushing 12 which determines a pivot axis 13 for a portion 14 of the wheel carrier 5. The portion 14 30 of the wheel carrier 5 is housed in the bushing 12 by means of a pin 15 and provided with a locking device 16, by means of which the part 14 can be arrested in its position in FIG. 1 for plow operation and in the position shown in FIG. 2 shows the pivot position for transport operation.

35 Ved de viste eksempler bestemmer den ydre leje bøsning 7 med sin akse 8 høj aksen for transport- 3In the examples shown, the outer bearing bush 7, with its axis 8, determines the high axis of transport 3.

drift, og mellemlejebøsningen 9 bestemmer med sin akse 10 pendulaksen for pløjedrift. Den omvendte funktion var imidlertid også mulig. For at sikre at hjulbæreren 5 i vendeplovens arbejdsstillinger kun er drejeligt be-5 vægelig om pendulaksen 10 og i vendeplovens transport-stilling kun er drejeligt bevægelig om højaksen 8, er der til valgfri frigivelse af hjulbæreren 5's bevægelighed om en af disse akser 8 og 9 et koblingsorgan, der ved de viste udførelsesformer omfatter en svingrigel 10 17 med et håndtag 18, der er svingbart lejret på mellemlej ebøsningen 9. Svingriglen 17 kan bringes til indgreb enten med låseanslag 19 på den ydre lejebøsning 7 eller med låseanslag 20 på hjulbæreren 5, og kan sikres i hver af disse indgrebsstillinger.operation, and the intermediate bearing sleeve 9 determines with its axis 10 the pendulum axis for plow operation. However, the reverse function was also possible. In order to ensure that the wheel carrier 5 in the working plow's working positions is only pivotally movable about the shaft axis 10 and in the transport position of the reversing plow is only pivotally movable about the high axis 8, there is an optional release of the wheel carrier 5's movement on one of these axes 8 and 9 a coupling means which in the embodiments shown comprises a pivot latch 10 17 with a handle 18 pivotally mounted on the intermediate bushing 9. The pivot latch 17 can be engaged either with locking stop 19 on the outer bearing bushing 7 or with locking stop 20 on the wheel support 5, and can be secured in each of these engagement positions.

15 Ved den i fig. 1 viste stilling af svingriglen 17 er mellemlej ebøsningen 9 låst sammen med den ydre lejebøsning 7, så at hjulbæreren 5 ved hjælp af sin tap 11 kun er svingbart bevægelig om pendulaksen 10 i mellemlejebøsningen 9. Hjulet 6 danner således et 20 pendulstøttehjul for pløj edrift af vendeploven, hvis støttestilling i arbejdsstillingerne bestemmes af på plovrammen 1 anbragte anslag 20 eller 21, der samvirker med modanslag 22 eller 23 på hjulbæreren 5. Disse modanslag 22 og 23 er af hensyn til ændring af støtte-25 stillingen udformet som indstillingsskruer, som det fremgår af fig. 3. Derfor er det muligt at indstille begge vendeplovens arbejdsstillinger uafhængigt af hinanden.15 In the embodiment of FIG. 1 of the pivot bolt 17, the intermediate bearing sleeve 9 is locked together with the outer bearing sleeve 7 so that the wheel carrier 5 is only pivotally movable about the shaft axis 10 in the intermediate bearing sleeve 9. The wheel 6 thus forms a pendulum support wheel for plowing operation. the reversing plow, if the supporting position in the working positions is determined by stops 20 or 21 arranged on plow frame 1, which cooperate with counter stops 22 or 23 on the wheel carrier 5. These counter stops 22 and 23 are designed as adjustment screws for the purpose of changing the supporting position 25, as can be seen. of FIG. 3. Therefore, it is possible to set the working positions of both reversing plows independently.

Ved den i fig. 2 viste transportstilling, ved 30 hvilken plovrammen 1 befinder sig i en halvdrejet mellemstilling mellem arbejdsstillingerne, og hvor delen 14 af hjulbæreren 5 er svinget 90° omkring svingaksen 13 i forhold til stillingen i fig. 1, er svingriglen 17 i indgreb med låseansatsene 20 på støttebæreren 35 5, så at mellemlejebøsningen 9 er arreteret i forhold til tappen 11. Som følge heraf er hjulbæreren 5 kun 4In the embodiment shown in FIG. 2, at which the plow frame 1 is in a semi-turned intermediate position between the working positions, and the part 14 of the wheel carrier 5 is pivoted 90 ° about the pivot axis 13 relative to the position of FIG. 1, the pivot latch 17 engages the locking lugs 20 of the support carrier 35 5 so that the intermediate bearing sleeve 9 is arranged relative to the pin 11. As a result, the wheel carrier 5 is only 4

drejelig om høj aksen, dvs. hjulbæreren 5 med tappen li og mellemlejebøsningen 9 kan dreje sig i den ydre lejebøsning. Yderlejebøsningen 7 bestemmer således en akse 8, der er indstillet således til plovrammen l's 5 transportstilling, at den danner en høj akse, dvs. forløber vinkelret på jorden.rotatable about the high axis, ie the wheel carrier 5 with the pin 1 and the intermediate bearing bushing 9 can rotate in the outer bearing bushing. The outer bearing sleeve 7 thus determines an axis 8 which is so adjusted to the transport position of plow frame 1 that it forms a high axis, i.e. extending perpendicular to the earth.

Den af mellemlejebøsningen 9 bestemte pendulakse 10 er således indstillet, at den i vendeplovens arbejdsstillinger forløber vinkelret på furevæggen, dvs.The pendulum axis 10 determined by the intermediate bearing bushing 9 is set so that in the working position of the reversing plow it extends perpendicular to the furrow wall, ie.

10 forløber vandret eller på tværs af vendeplovens arbejds-retning. Begge akser ligger fortrinsvis i ét plan og skærer hinanden under en spids vinkel a, der tager hensyn til forskellene ved indstilling, af plovrammen i arbejdsstillingerne og i vendeplovens transportstilling.10 runs horizontally or transversely of the working plow's working direction. Both axes preferably lie in one plane and intersect at an acute angle α, taking into account the differences in alignment, of the plow frame in the working positions and in the transport position of the reversing plow.

15 Den i fig. 4 viste anden udførelsesform for leje organet 4 anviser en mulighed for, at akserne 8 og 10 kan indstilles uafhængigt af hinanden i forhold til plovrammen. Som det fremgår nærmere af fig. 4, er tappen li lejret i mellemlejebøsningen 9 ved hjælp af en le-20 jekugle 24, der er forsynet med en tilsvarende kugleformet indre lejedel 25. Til vinkelindstilling tjener et indstillingsorgan 26, ved hjælp af hvilken stillingen af tappen 11 kan indstilles og fikseres i mellemlej ebøsningen 9. Dettes indstillingsorgan 26 omfatter 25 igen en kuglelejring 27 for tappen '11, og den ydre lejering 28 er forskydelig og låsbar ved hjælp af en indstillingsskrue 29 i det fælles plan for akserne 8 og 10.15 The embodiment of FIG. 4, the second embodiment of the bearing means 4 provides a possibility that the axes 8 and 10 can be adjusted independently of one another relative to the plow frame. As can be seen in more detail in FIG. 4, the pin 1 is mounted in the intermediate bearing sleeve 9 by means of a bearing ball 24 provided with a corresponding spherical inner bearing member 25. For angular adjustment, an adjusting means 26, by means of which the position of the pin 11 can be adjusted and fixed, is provided. the intermediate bushing 9. This adjusting member 26 again comprises a ball bearing 27 for the pin 11, and the outer bearing 28 is slidable and lockable by means of an adjusting screw 29 in the common plane of the axes 8 and 10.

På tilsvarende måde er også mellemlejebøsningen 30 9 lejret ved hjælp af en kuglelejring 30 i den ydre lejebøsning 7 og er støttet vinkelindstilleligt ved hjælp af et indstillingsorgan 31. Til dette formål er mellemlejebøsningen 9 forsynet med en kugleformet, ydre lejeflade 32, og den ydre lejebøsning 7 er forsy-35 net med en tilsvarende kugleformet lejedel 33. Indstillingsorganet 31 svarer til indstillingsorganet 26 ogSimilarly, the intermediate bearing sleeve 30 9 is also supported by a ball bearing 30 in the outer bearing sleeve 7 and is supported angularly adjustable by an adjusting member 31. For this purpose, the intermediate bearing sleeve 9 is provided with a spherical outer bearing surface 32, and the outer bearing sleeve 7 is provided with a corresponding spherical bearing member 33. The adjusting member 31 corresponds to the adjusting member 26 and
