Den foreliggende frembringelse angår en kombineret plov og jordbearbejdningsapparat af den i indledningen til krav 1 angivne art.The present invention relates to a combined plow and tillage device of the kind specified in the preamble of claim 1.

I forbindelse med liftmonterede og/eller halv-bugserede vendeplove er det et kendt sag, at det kan være problematisk at arbejde med efterkoblede jordbearbejdningsapparater. Navnlig ved markens respektive ender forekommer der tekniske problemer under vendingerne, fordi det ved hjælp af komplicerede koblingsorganer er nødvendigt midlertidigt at fra- og tilkoble efterkoblede apparater. Desuden er det en ulempe, at kendte vendeplove, hvor det er muligt at efterkoble jordbearbejdningsapparater, kræver anvendelse af meget kraftige og dyre traktorer, der yderligere på grund af deres egenvægt forøger risiko for såkaldt traktose, dvs. hvor tung trafik sammenpresser jorden.In the case of lift-mounted and / or semi-towed reversing plows, it is a known case that it can be problematic to work with post-coupled tillage machines. Especially at the respective ends of the field, technical problems occur during the turns, because it is necessary to temporarily disconnect and switch on switched devices by means of complicated coupling means. In addition, it is a disadvantage that known reversing plows, where it is possible to disconnect tillage machines, require the use of very powerful and expensive tractors which further increase the risk of so-called tractose, because of their own weight. how heavy traffic compresses the ground.

Frembringelsen har til formål at angive en forbedret kombineret plov og jord-bearbejdsningsapparat af den indledningsvis angivne type, og som gør det muligt at imødekomme de nævnte ulemper.The object of the present invention is to provide an improved combined plow and soil tillage apparatus of the type mentioned in the preamble, which makes it possible to meet the disadvantages mentioned.

Ploven ifølge frembringelsen er kendetegnet ved, at en central bærebjælke for ploven er svingbart lejret i en bæreramme, hvis forreste ende omfatter nævnte træk- og vendehoved, og hvis bageste ende omfatter et bageste vendehoved for plovens bærebjælke, hvilken bæreramme fortrinsvis i nærheden af nævnte bageste ende ved hver sin side er forsynet med hjul, fortrinsvis luftgummihjul, der skiftevis virker som dybde- eller landhjul, der kører på den upløjede jord, henholdsvis let- eller fortrinsvis ubelastet hjul, der kører i den nypløjede jord, og at den bageste del af bærerammen desuden omfatter koblingsorganer for et eller flere efterkoblede jordbearbejdningsapparater, f.eks. en jordpakker, en såmaskine eller en kombineret såmaskine og gødskningsudstyr. Ved hjælp af enkle foranstaltninger opnås herved en forbedret halv-bugseret vendeplov, der sammenlignet med tilsvarende lift-ophængte vendeplove med samme kapacitet kan trækkes af en lettere og billigere traktor, og som ikke giver nævnte fra- og tilkoblingsproblemer i forbindelse med vendingerne ved markens respektive ender.The plow according to the invention is characterized in that a central support beam for the plow is pivotally mounted in a supporting frame, the forward end of which comprises said pulling and turning head, and the rear end of which comprises a rear turning head of the plow supporting beam, preferably supporting said rear end on each side is provided with wheels, preferably air rubber wheels, which alternately act as depth or shore wheels running on the plowed ground, respectively light or preferably unloaded wheels running in the newly plowed ground, and that the rear part of the the support frame further comprises coupling means for one or more post-coupled tillers, e.g. a soil compactor, a seed drill or a combined seed drill and fertilizer equipment. By means of simple measures, an improved semi-towed plow can be obtained, which can be pulled by a lighter and less expensive tractor compared to similar lift-mounted reversed plows with the same capacity, and which does not cause the said disconnection and coupling problems in connection with the turns at the respective fields. ends.

Hensigtsmæssigt kan ploven ifølge frembringelsen være således udformet, at nævnte koblingsorganer for nævnte efterkoblede jordbearbejdningsapparat omfatter et fortrinsvis 2 DK 97 00238 U3 hydraulisk betjent armsystem, der er indrettet således, at det nævnte hjul, der kører i den nypløjede jord, kan være helt aflastet.Conveniently, the plow according to the invention may be designed such that said coupling means for said post-coupled tillage apparatus comprises a preferably hydraulically operated arm system which is arranged so that said wheel running in the newly plowed soil can be completely unloaded.

Med særlig fordel kan ploven ifølge frembringelsen yderligere være udformet således, at der mellem bærerammen og nævnte hjul er indskudt organer, der er indrettet til at højdeindstilling af bærerammen i forhold til jordoverfladen.With particular advantage, the plow according to the invention can be further designed so that means are inserted between the support frame and said wheels, which are arranged for height adjustment of the support frame relative to the ground surface.

Ploven ifølge frembringelsen er desuden fortrinsvis udformet således, at mindst et af nævnte vendehoveder for plovens bærebjælke er indrettet til at kunne forskydes i sideretningen, fortrinsvis ved hjælp af en eller flere hydrauliske cylindre.In addition, the plow according to the invention is preferably designed such that at least one of said pivoting heads of the plow support beam is arranged to be displaceable in the lateral direction, preferably by means of one or more hydraulic cylinders.
