Opfindelsen angår en radsåmaskine af den i indledningen til krav 1 angivne art.The invention relates to a seed drill of the kind specified in the preamble of claim 1.

En sådan radsåmaskine kendes fra tysk offentliggørelsesskrift nr. 30 00 959. Denne radsåmaskine har i praksis vist sig at 5 være pålidelig og udmærker sig blandt andet ved at radsåskærene er anbragt med små rækkeafstande. Herved kan opnås et større høstudbytte, fordi såmaterialet bliver udbragt med en mere ensartet fordeling. Endvidere bliver muligheden for at flere frøkerner bliver aflagt tæt ved hinanden, formind-10 sket ved aflægning af såmaterialet med små rækkeafstande.Such a seed drill is known from German Publication No. 30 00 959. This seed drill has in practice proved to be reliable and is distinguished, among other things, by the fact that the seed drills are placed with small row spacings. This results in a greater yield, because the seed material is distributed with a more uniform distribution. Furthermore, the possibility of multiple seed cores being deposited close to each other is reduced by depositing the seed material with small row spacings.

En ulempe ved denne radsåmaskine er dog, at der til løsnen af radsåmaskinens kørehjulspor må anvendes sporløsnere. Prem for alt på svære jorder er løsningseffekten af disse spor-løsnere fuldstændig utilstrækkelig. Radsåskærene kan kun 15 nedfælde såmaterialet utilstrækkeligt i jorden i de kun utilstrækkeligt løsnede kørehjulspor. Det er heller ikke muligt altid at placere radsåskærene i kørehjulsporenes ydre kanter, fordi kørehjulene har en bredde på mellem 120 og 170 mm, medens radsåskærene imidlertid er anbragt med en rækkeafstand 20 på 8 til 10 cm. Det ville give store frie spor, i hvilke der ikke var nedfældet såmateriale.However, one disadvantage of this seed drill is that track looser must be used for loosening the seed drill's track wheel. Premise for everything on heavy soils, the dissolution effect of these track-loosers is completely insufficient. The row saw cutters can only settle the seed material insufficiently in the soil in the only loosely cast wheel tracks. Also, it is not always possible to place the row cutters at the outer edges of the drive wheel tracks, because the drive wheels have a width of between 120 and 170 mm, while the row cutters are, however, arranged with a row spacing 20 of 8 to 10 cm. This would give great free traces in which no seed material was deposited.

Formålet med opfindelsen er væsentligt at forenkle og forbedre nedfældningen af såmaterialet i kørehjulsporene.The object of the invention is to significantly simplify and improve the deposition of the seed material in the driving wheels.

Dette opnås ifølge opfindelsen ved hjælp af det i den kende-25 tegnende del af krav 1 anførte. Ifølge disse foranstaltninger bliver såmaterialet også i kørehjulsporene nedfældet i den foreskrevne optimale dybde i jorden. Endvidere følger heraf den fordel, at der til løsnen af kørehjulsporene ikke skal anvendes nogen yderligere sporløsnere.This is achieved according to the invention by means of the characterizing part of claim 1. According to these measures, the seed material is also deposited in the track wheels at the prescribed optimum depth in the soil. Furthermore, there is the advantage that no additional track loosers are used for loosening the driving wheels.

30 Desuden findes der ifølge opfindelsen i hvert kørehjulspor kun et enkelt opbrydningsiskær, hvor opbrydningsskæret så har en bredde, som tilnærmelsesvis svarer til bredden af kørehjulet.In addition, according to the invention, in each driving wheel groove, there is only a single breaking cutter, the breaking cutting edge then having a width which corresponds approximately to the width of the driving wheel.

Ved denne foranstaltning kommer der ved en reducering af de nødvendige radsåskær en omkostningsbesparelse og en forbedret nedfældning af såmaterialet i kørehjulsporet.By this measure, a reduction of the necessary row cutters will result in cost savings and an improved deposition of the seed material in the driving wheel track.

På enkel måde kan der i kørehjulsporene opnås den samme udså-5 ningsmængde pr. fladeenhed som på den øvrige flade, der skal bearbejdes, ved at der til opbrydningsskæret tilføres såmateriale fra to doseringselementer.In simple terms, the same amount of seed can be obtained in the driving wheel tracks per day. surface unit as on the other surface to be machined by adding seed material from two dosing elements to the breaking cutter.

yderligere enkeltheder ved opfindelsen fremgår af de yderligere underkrav og af den detaljerede beskrivelse i forbin-10 delse med tegningen, hvor fig. 1 skematisk viser en udførelsesform for en radsåmaskine ifølge opfindelsen set bagfra, fig. 2 skematisk placeringen af radsåskærene ifølge opfindelsen set ovenfra og 15 fig. 3 skematisk radsåmaskinen ifølge opfindelsen set fra siden.Further details of the invention will be apparent from the further subclaims and from the detailed description of the drawings, in which: FIG. 1 is a schematic rear view of an embodiment of a row seeder according to the invention; FIG. 2 is a schematic top view of the row cutter according to the invention; and FIG. 3 is a schematic side view of the row seed drill according to the invention.

Radsåmaskinen er forsynet med en ramme 1, som i driftsstillingen hviler på kørehjulene/på jorden 3 med en forrådsbeholder 4. I den nedre del af forrådsbeholderen 4 findes doserings-20 elementerne 5, fra hvilke det i forrådsbeholderen 4 anbragte såmateriale i indstillelige mængder på kendt måde gennem rørledningerne 6 og ved hjælp af radsåskærene 7 bliver nedfældet i jorden 3.The seed drill is provided with a frame 1 which, in its operating position, rests on the drive wheels / on the ground 3 with a storage container 4. In the lower part of the storage container 4 are the metering elements 5, from which the seed material placed in the storage container 4 in adjustable quantities on known way through the pipelines 6 and with the aid of the row cutters 7 is deposited in the soil 3.

De mellem kørehjulene 2 anbragte radsåskær 7 er udformet som 25 enkelttallerkenskær 8. Enkelttallerkenskærene 8 er anbragt med mellemrum i tre bag ved hinanden liggende tværrækker med en meget lille rækkeafstand fra hinanden. Rækkeafstanden mellem de ved siden af hinanden liggende enkelttallerkenskær udgør ved den såkaldte finsåmaskine ca. 8 til 10 cm.The row cutting inserts 7 arranged between the drive wheels 2 are formed as 25 single-disc inserts 8. The single-disc inserts 8 are arranged at intervals in three adjacent transverse rows with a very small row spacing from each other. The row spacing between the adjacent single disc cutters is approx. 8 to 10 cm.

3 I hvertaf de af kørehjulene 2 frembragte kørehjulspor 9 er anbragt et som et opbrydningsskær 10 udformet radsåskær. Opbrydningsskæret 10 har en bredde h, som tilnærmelsesvis svarer til bredden 1 af kørehjulet 2. Herved bliver foruden en 5 løsnen af kørehjulsporet 9 opnået, at den i randområderne af kørehjulsporet 9 løse jord yderligere bliver løftet af op-brydningsskaeret 10 og bliver kastet hen over det i kørehjul-sporet nedfældede såmateriale. For at opbrydningsskæret 10 selv skal trække sig ned i jorden 3, er dens forreste nedre 10 del 11 rettet let fremad og nedad.3 In each of the drive wheels 9 produced by the drive wheels 2 is arranged a row cutter shaped as a breaking insert 10. The breaking insert 10 has a width h which corresponds approximately to the width 1 of the driving wheel 2. This, in addition to a loosening of the driving wheel track 9, is achieved so that the soil loose in the peripheral areas of the driving wheel track 9 is further lifted by the breaking cutting edge 10 and is thrown over the seed material deposited in the drive wheel track. In order for the breaking cut 10 itself to penetrate into the ground 3, its front lower part 10 is directed slightly forward and downward.

Opbrydningsskærets 10 indtrængningsdybde t i jorden bliver bestemt af kørehjulene 2 og de indstillelige anslag 12. For at opbrydningsskæret skal være beskyttet mod beskadigelser ved at ramme i jorden 3 værende forhindringer, kan det af-15 vige elastisk imod fjederkraften af den på den opad afbøjede del af skærholderen 13 anbragte trækfjeder 14.The penetration depth of the breaking insert 10 to the ground is determined by the drive wheels 2 and the adjustable stops 12. In order for the breaking insert to be protected against damage by impinging in the ground 3, it can deviate elastically against the spring force of the upwardly deflected part of the the cutter holder 13 provided tension spring 14.

De rørledninger 61, som tilfører såmaterialet til opbrydningsskærene 10, er hver tilsluttet to doseringselementer 5 for på enkel måde at udbringe samme såmaterialemængde pr. fladeenhed 20 i kørehjulsporene 9 som på den øvrige jord mellem kørehjulene 2 . På enkel måde bliver herved hver af rørledningerne 6" tilsluttet tragten 15, som samler det fra to doseringselementer doserede såmateriale.The pipelines 61 supplying the seed material to the breaking cutters 10 are each connected to two metering elements 5 in order to easily dispense the same amount of seed material per meter. surface unit 20 in the drive wheels 9 as on the other ground between the drive wheels 2. In this way, each of the pipelines 6 "is connected to the hopper 15 which collects the seed material dosed from two metering elements.
