Opfindelsen angår en maskine til udplantning af separate spiringselementer, som indeholder frø, forspirede frø eller helt fremspirede planter, hvilken maskine omfatter en ramme med en forrådsbeholder for spiringselementer og mindst en trækstang til tilslutning af rammen til en traktors redskabsbom og et højdeindstilleligt forhjul samt eventuelt en forplov, og hvor 5 der på rammen er monteret en planteenhed med et skær til dannelse af en fure, og et bag ved skæret placeret sæt sammentrykningshjul til lukning og sammentrykning af den af skæret dannede fure, og hvor der ledende ned i skæret og rettet ned mod furens bund er monteret et nedføringsorgan, som er indrettet til successiv nedføring af separate spiringselementer, medens der mellem forrådsbeholderen og nedføringsorganet er monteret et ledeor-10 gan til fremføring, separering og aflevering af spiringselementerne separat til nedføringsor-ganet, hvilke spiringselementer foreligger sammenhængende i båndform, idet hvert spiringselement har et gribehul, og der i båndet mellem to på hinanden følgende spiringselementer er tildannet en eller flere gennemskæringer.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a machine for planting separate germinating elements containing seeds, germinated seeds or fully germinated plants, the machine comprising a frame with a storage container for germinating elements and at least one drawbar for connecting the frame to a tractor implement boom and a height adjustable front wheel as well as an optional plow, and wherein a plant unit is mounted on the frame with a cutter for forming a groove, and a set of compression wheels located behind the cutter for closing and compressing the groove formed by the cutter, and where leading down into the cutting and straightening down against the bottom of the furrow is mounted a downwardly arranged for successively downward of separate germinating elements, while there is mounted a guide means for feeding, separating and delivering the germinating elements separately to the downward means, which germinating elements are continuous in band shape, with h the host germination element has a gripping hole and one or more intersections are formed in the band between two successive germination elements.

Fra beskrivelsen til US patent nr. 4.597.443 kendes en maskine til udplantning af separate 15 spiringselementer, som indeholder ffemspirende planter; maskinen omfatter en ramme med en forrådsbeholder samt et forhjul. På rammen er der monteret en planteenhed med et skær til dannelse af en fure, og bag ved skæret er der placeret sammentrykningshjul til lukning og sammenpresning af den af skæret dannede fure. Ledende ned i skæret og rettet mod furens bund er der monteret et nedføringsorgan, som er indrettet til successiv nedføring af 20 separate spiringselementer. Mellem forrådsbeholderen og nedføringsorganet er der monteret ledeorganer til fremføring, separering og aflevering af spiringselementerne separat til nedføringsorganerne. Denne maskine, som er beregnet til manuel fremføring, virker dog ikke helt tilfredsstillende, fordi udplantningen foregår ret langsomt, og det enkelte spiringselement under udplantningen ikke gribes nøjagtigt nok.From the specification of US Patent No. 4,597,443, a machine for planting separate germinating elements containing five germinating plants is known; the machine includes a frame with a storage container as well as a front wheel. On the frame is mounted a plant unit with a cutter to form a groove, and behind the cutter are compression wheels for closing and compressing the groove formed by the cutter. Conducting down into the cutter and facing the bottom of the furrow, a down member is mounted which is arranged for successively downward of 20 separate germinating elements. Guide means for feeding, separating and delivering the sprouting elements separately to the feeding means are mounted between the storage container and the downstream means. However, this machine, which is intended for manual feeding, does not work completely satisfactorily, because the propagation takes place quite slowly and the individual germination element during the planting is not grasped precisely enough.

25 Formålet med opfindelsen er at anvise en maskine af den indledningsvis nævnte art, som dels kan arbejde meget hurtigt, dels gribe det enkelte spiringselement mere nøjagtigt end kendt.The object of the invention is to provide a machine of the kind mentioned initially, which can work very quickly and partly to grasp the individual germination element more accurately than known.

Maskinen ifølge opfindelsen er ejendommelig ved, at ledeorganet er udformet som et rør med i hovedsagen rektangulært tværsnit, og som kan lede båndet hen til nedføringsorganet, og at nedføringsorganet udgøres af et hjul med radialt rettede tappe, hvis indbyrdes afstand svarer til den ønskede planteafstand i jorden, og at røret ved dets ydre ende er buet udad i 5 forhold til hjulets periferi og er forsynet med en skarp afrivningskant, hvilken ydre ende på den side, der vender mod hjulet, har en i rørets længderetning gående slids til optagelse af hjulets radiale tappe, når hjulet under driften af maskinen ruller i bunden af furen, så at tappene successivt kan indgribe i spiringselementernes huller. Herved opnås, at det spirings-element, der ligger yderst i ledeorganet, automatisk vil blive frigjort meget nøjagtigt og 10 pålideligt fra den resterende del af spiringsbåndet, idet en af hjulets tappe vil kunne gribe fat i det nævnte spiringselement og grundet ledeorganets skarpe afrivningskant afrive det nævnte spiringselement fra den resterende del af båndet. Når et spiringselement er grebet af en tap, følger det med tappen ned til bunden af furen eller i nærheden heraf, hvor det frigøres og af hjulet trykkes til i furen. Hele dette forløb kan foregå meget hurtigt og pålide-15 ligt, når maskinen af traktoren trækkes hen over den mark, hvor udplantningen skal ske.The machine according to the invention is characterized in that the guide member is formed as a tube of substantially rectangular cross-section and which can guide the belt to the down member and that the down member is constituted by a wheel with radially directed pins whose spacing corresponds to the desired plant distance in the ground, and that the tube at its outer end is curved outwardly relative to the periphery of the wheel and is provided with a sharp tear-off edge, which outer end of the side facing the wheel has a longitudinally extending slot for receiving the radial of the wheel. pin as the wheel rolls at the bottom of the groove during operation of the machine so that the pins can successively engage the gaps of the sprouting elements. Hereby it is achieved that the germinating element which is outermost in the guide means will automatically be released very accurately and reliably from the remaining part of the germination belt, as one of the pins of the wheel will be able to grip said germinating element and, due to the sharp ripening edge of the guide member, said germination element from the remainder of the belt. When a germination element is gripped by a pin, it follows the pin down to the bottom of the groove or near it where it is released and the wheel is pressed into the groove. This entire process can take place very quickly and reliably when the machine is pulled by the tractor across the field where the planting is to be done.

Ifølge opfindelsen kan der på skæret - og indrettet til samvirke med nedføringshjulet - være monteret et afstrygningsorgan med et eller to tynde stålblade, der under hjulets rotation kan føres ind mellem hjulet og spiringselementet og afstryge sidstnævnte fra tappen. Derved opnås en særligt pålidelig frigørelse af det enkelte spiringselement fra nedføringshjulet, 20 således at spiringselementet falder ned i furen på et ønsket sted og trykkes til af hjulet.According to the invention, there may be mounted on the cutter - and adapted to cooperate with the descending wheel - a wiping means with one or two thin steel blades which, during rotation of the wheel, can be inserted between the wheel and the germinating element and stripping the latter from the pin. Thereby, a particularly reliable release of the individual sprouting element is obtained from the down wheel, so that the sprouting element falls into the groove at a desired location and is pressed by the wheel.

Desuden kan der ifølge opfindelsen på skæret ud for eller nær ved hjulets bagside være monteret jordafrensningsorganer, f.eks. i form af skrabere og/eller børster til rensning af hjulet. Derved opnås, at maskinen arbejder lige godt i tør, kornet jord som fedtet eller klumpet jord. Jordklumper eller jordblokke, som måtte have sat sig fast på den nederste del 25 af nedlægningshjulet, vil på meget pålidelig måde blive skrabet/fejet af hjulet.In addition, according to the invention, on the cutting edge next to or near the rear of the wheel may be ground cleaning means, e.g. in the form of scrapers and / or brushes for cleaning the wheel. This ensures that the machine works just as well in dry, grainy soil as greasy or lumpy soil. Lumps of earth or blocks that may have stuck to the lower part 25 of the laying wheel will be reliably scraped / swept by the wheel.

Endvidere er det ifølge opfindelsen muligt, at nedføringshjulet kan være monteret i et separat ophæng på skæret. Derved opnås enkel konstruktion.Furthermore, according to the invention, it is possible that the descending wheel may be mounted in a separate suspension on the cutting insert. This results in simple construction.

Ifølge opfindelsen kan rammen være forsynet med en sekskantmuffe, hvori en på planteen-heden monteret sekskantstang kan indskydes med henblik på tilslutning af maskinen til traktoren. Denne måde at fastgøre maskinen til traktoren på har vist sig særlig simpel.According to the invention, the frame can be provided with a hexagon socket in which a hexagon rod mounted on the plant unit can be inserted for connection of the machine to the tractor. This way of attaching the machine to the tractor has proved particularly simple.

Endelig kan der ifølge opfindelsen på rammen foran skæret være monteret injektorer til 5 nedfældning af gødningsstoffer i jorden, især til erstatning for de gødningssstoffer, der medgår til nedbrydning af spiringselementerne i jorden. Herved opnås på let måde mulighed for at kompensere for det gødningstab, som bionedbrydningen af spiringselementet i jorden medfører.Finally, according to the invention, on the frame in front of the insert, injectors may be mounted for precipitation of fertilizers in the soil, in particular to replace the fertilizers which are used to break down the germinating elements in the soil. This provides an easy way to compensate for the loss of fertilizer caused by the biodegradation of the germinating element in the soil.
