i DK 169160 B1 SÅINDRETNING.in DK 169160 B1 SEED INSTALLATION.
Den foreliggende opfindelse angår en såindretning, ved 5 hvilken der i et såhus drejefast på en såaksel er anbragt et finsåningshjul, der har knaster, og hvor der ved siden af finsåningshjulet drejeligt på såakslen er placeret et normalsåningshjul, der ligeledes har knaster, og ved hvilken normalsåningshjulet for sammenkobling med finsånings-10 hjulet har et aksialt forskydeligt passtykke, der kan skydes formsluttende ind i en udsparing i finsåningshjulet.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sowing device, in which a fine sowing wheel having cams is arranged in a seed house pivotally fixed to a seed shaft, and in which a normal sowing wheel also having cams is placed next to the fine sowing wheel. The normal seed wheel for coupling with the fine sowing wheel has an axially displaceable pass piece which can be slid molded into a recess in the fine sowing wheel.
DE patentskrift nr. 837 022 beskriver en sådan såindretning.DE patent specification 837 022 discloses such a sowing device.
15 På den kendte såindretning findes der som passtykke (koblingsstykke) en forskydeligt anbragt stift i en aksial boring på normalsåningshjulet, der alt efter sin stilling, der er givet på forhånd ved hjælp af to låsefordybninger, 20 enten med sin ende rager ind i et gennembrud på huset, eller med sin anden ende rager ind i et gennembrud på finsåningshjulet. Derved er normalsåningshjulet enten forbundet med huset og herigennem sikret mod at dreje, eller det er koblet sammen med finsåningshjulet, så det roterer synkront 25 med dette.15 In the known sowing device there is provided as a fitting piece (coupling piece) a displaceable pin in an axial bore of the normal sowing wheel which, depending on its position, provided in advance by two lock recesses, 20 either with its end projecting into a breakthrough on the house, or with its other end protrudes into a breakthrough on the fine-tuning wheel. Thereby, the normal sowing wheel is either connected to the housing and thereby secured against turning, or it is coupled to the fine sowing wheel so that it rotates synchronously therewith.
Ved at der gives denne mulighed for frakobling af normalsåningshjulet kan man for småfrø, når såakslen roterer med et konstant omdrejningstal, nedsætte den udstrøede mængde be-30 tragteligt. Transmissionsgearet til trækket af såakslen kan så klare sig med mindre trin, så det kan forenkles. En ulempe ved den kendte såindretning er måden, hvorpå pas-stykket betjenes.By allowing this opportunity to disengage the normal sowing wheel, for small seeds, when the seed shaft rotates at a constant speed, the amount of scattered seed can be considerably reduced. The transmission gear for the pull of the seed shaft can then cope with smaller steps so that it can be simplified. A disadvantage of the known sowing device is the way in which the passport is operated.
35 Da radsåmaskiner i overensstemmelse med deres arbejdsbredde har et større antal såindretninger ved siden af hverandre, DK 169160 B1 2 er stifterne,som kun er tilgængelige fra siden, svære at betjene. Hertil kommer, at stifterne ofte på grund af tilsmudsning går tungt, hvilket yderligere vanskeliggør driften.35 As row saws, in accordance with their working width, have a larger number of seed devices side by side, the pins, which are only accessible from the side, are difficult to operate. In addition, due to soiling, the pins are often heavy, which further complicates the operation.
55
Formålet med opfindelsen er at tilvejebringe en såindretning af den i indledningen angivne art, med hvilken til- og frakobling af normalsåningshjulet kan gennemføres på den mest enkle måde.The object of the invention is to provide a sowing device of the kind specified in the preamble with which connection and disconnection of the normal sowing wheel can be carried out in the simplest manner.
1010
Denne opgave løses ved en såindretning af den indledningsvist omhandlede art, hvilken såindretning ifølge opfindelsen er særegen ved, at passtykket er udformet som en knast på normalsåningshjulet og er anbragt aksialt forskydeligt 15 herpå.This task is solved by a sowing device of the kind referred to in the preamble, which sowing device according to the invention is peculiar in that the fit piece is formed as a cam on the normal sowing wheel and is axially displaceable thereon.
Ved denne udformning kan til- og frakobling af normalsåningshjulet ske ved at forskyde en stang på ydersiden af radsåmaskinens bagside. Man behøver derfor ikke mere fra 20 siden at nå ind til det dårligt tilgængelige og næppe synlige område ved siden af de enkelte såindretninger for at gennemføre til- eller frakoblingen. Derved er det muligt at foretage en hurtigere og nemmere omstilling af såindretningerne, end det er muligt ved kendte radsåmaskiner. Desuden 25 kan man med ét blik fra radsåmaskinens bagside finde ud af, i hvilken stilling passtykkerne befinder sig.In this embodiment, the normal sowing wheel can be switched on and off by displacing a rod on the outside of the back seed drill. Therefore, no more than 20 pages need to reach the poorly accessible and barely visible area next to the individual seed devices to complete the connection or disconnection. This makes it possible to make a quicker and easier conversion of the sowing devices than is possible with known row sowing machines. In addition, one can at a glance from the back of the row seed drill find out in what position the pieces of fit are located.
Særlig enkel viser såindretningens konstruktion sig at være, når passtykket gennem en aksial slids griber ind i nor-30 malsåningshjulets kappeoverflade.Particularly simple, the construction of the sowing device appears to be when the pass piece engages through an axial slot into the casing surface of the normal sowing wheel.
Man kan med såindretningen ifølge opfindelsen på ganske enkel måde undgå, at normalsåningshjulet på grund af friktionskræfter uønsket drejer rundt sammen med finsåningshjulet 35 på samme måde som ved de hidtil kendte såindretninger, hvis passtykket er udformet, så det i en første stilling på en DK 169160 B1 3 side rager aksialt ud af normal såningshjulet og griber ind i en udsparing på huset, og i sin anden stilling aksialt ud af normalsåningshjulet griber ind i udsparingen på finså-ningshj ulet.With the sowing device according to the invention it is quite simple to avoid that the normal sowing wheel, because of frictional forces, undesirably rotates together with the fine sowing wheel 35 in the same way as with the known sowing devices, if the fit piece is designed so that in a first position on a DK 169160 The B1 3 side projects axially out of the normal sowing wheel and engages in a recess on the housing, and in its second position axially out of the normal sowing wheel engages in the recess on the fine sowing wheel.
55
Passtykkets to stillinger kan på enkel måde være defineret ved hjælp af låsefordybninger på passtykkets underside, med hvilke låsefordybninger en kugle kan raste ind, hvilken kugle sidder i en radial boring på normalsåningshjulet og 10 er radialt forspændt hen mod låsefordybningerne.The two positions of the pass piece can be simply defined by means of lock holes on the underside of the pass piece, with which lock holes a ball can enter, which ball is in a radial bore on the normal sowing wheel and is radially biased towards the lock holes.
En anden fordelagtig udformning af såindretningen ifølge opfindelsen består i, at det trin, der skal overvindes ved forskydningen af passtykket mellem låsefordybningeme, har 15 en ringere højde end de aksialt ved siden af låsefordybningerne liggende områder af passtykket.Another advantageous embodiment of the sowing device according to the invention consists in that the step to be overcome in the displacement of the pass piece between the lock recesses has a lower height than the axially adjacent the lock recesses.
Ved denne udformning kan omstillingen af passtykket ske med en relativt ringe kraft. Til komplettering af passtykket må 20 et højere trin dog overvindes, så passtykket holdes sikkert i normalsåningshj ulet.In this design, the adjustment of the passport can be done with a relatively low force. However, for completing the passport, a higher step must be overcome so that the passport is securely held in the normal sowing wheel.
En tilsmudsning af fordybningerne kan undgås, såfremt låsefordybningerne i passtykkets to koblingsstillinger er an-25 bragt inden for normalsåningshjulets kontur.A soiling of the recesses can be avoided if the lock recesses in the two coupling positions of the passport are positioned within the contour of the normal sowing wheel.
Såindretningens udsåningsmængde kan ved konstant omdrej -ningstal forandres i tre trin, såfremt der ifølge en anden fordelagtig udformning af opfindelsen på begge sider af et 30 finsåningshjul er anbragt henholdsvis et normalsåningshjul med en forskydelig knast og et passtykke.The seeding quantity of the sowing device can be changed in three steps at constant rpm if, according to another advantageous embodiment of the invention, on both sides of a fine sowing wheel, respectively, a normal sowing wheel with a displaceable cam and a fitting piece is arranged.
Det er også fordelagtigt, såfremt finsåningshjulet henimod normalsåningshjulet har en manchetlignende ansats med en 35 omløbende radial låseforhøjning, og at normalsåningshjulet har en tilsvarende manchetlignende ansats, der griber ind DK 169160 B1 4 over finsåningshjulets ansats med en låsefordybning, der griber ind over låseforhøjningen.It is also advantageous if the fine sowing wheel opposite the normal sowing wheel has a cuff-like shoulder with a circumferential radial locking elevation, and that the normal sowing wheel has a similar cuff-like shoulder which engages the locking eye with a locking eye cushion with a locking eye cushion.
Ved denne udformning kan hele såindretningen samles til en 5 enhed, allerede før den indbygges i et såhus, hvilket letter dens montage.In this design, the entire seed device can be assembled into a 5 unit, even before it is built into a seed house, which facilitates its assembly.
Passtykket betjenes specielt enkelt og godt, såfremt passtykket med et føringsstykke sidder mellem den manchetlig-10 nende ansats og en kappeoverflade på normalsåningshjulet og griber ind med en føringsliste, der har en knast, ved hjælp af en slids i kappeoverfladen.The passport piece is particularly simple and well operated if the passport with a guide piece sits between the cuff-like abutment and a casing surface on the normal sowing wheel and interacts with a guide strip having a cam through a slot in the casing surface.
Det er også fordelagtigt, såfremt udsparingerne i finså-15 ningshjulet er anbragt i en vinkel til hinanden på højst 90°.It is also advantageous if the recesses of the fine-cutting wheel are disposed at an angle to each other of not more than 90 °.
Ved denne udformning opnås det, at både det højre og det venstre normalsåningshjul lader sig til- henholdsvis fra-20 koble, når en markering på finsåningshjulet, som er anbragt mellem de to udsparinger, i den bagfra tilgængelige stilling, står lodret fra oven.In this embodiment, it is achieved that both the right and left normal sowing wheels can be disengaged and disengaged, respectively, when a mark on the fine sowing wheel, which is placed between the two recesses, in the rear accessible position, stands vertically from above.
Den foreliggende opfindelse tillader talrige udførelsesfor-25 mer. Heraf vises og beskrives efterfølgende en af disse på tegningen. På tegningen viser:The present invention allows numerous embodiments. One of these is shown and described in the drawing. In the drawing:
Fig. 1 en såindretning ifølge opfindelsen set fra siden, 30 fig- 2 et snit gennem den i fig. 1 viste såindretning langs linien II-II, fig. 3 set fra siden et passtykke på den i fig. 1 viste såindretning, og 35 fig. 4 et passtykke set forfra ifølge fig. 2.FIG. 1 is a side view of a sowing device according to the invention; FIG. 1, along the line II-II, FIG. 3 is a side view of a passport of the one shown in FIG. 1, and FIG. 4 is a front view of a passport according to FIG. 2nd
DK 169160 B1 5 I fig. 1 og 2 vises en såaksel 1, der løber igennem et såhus 2. I såhusets 2 indre er der på såakslen 1 drejefast anbragt et finsåningshjul 3. Den drejefaste forbindelse op-5 nås på sædvanlig måde ved hjælp af en feder 5, der sidder på en not 4 på såakslen 1 og griber ind med en tilsvarende not 6 på finsåningshjulet 3.DK 169160 B1 5 In fig. 1 and 2, a seed shaft 1 is shown which runs through a seed housing 2. In the seed housing 2, a fine sowing wheel 3 is mounted on the seed shaft 1. The pivotal connection is reached in the usual way by means of a spring 5 mounted on it. a groove 4 on the seed shaft 1 and engages a corresponding groove 6 on the fine sowing wheel 3.
I det følgende beskrives såindretningen overvejende ved 10 hjælp af fig. 2, idet der kun lejlighedsvis henvises til fig. 1. Finsåningshjulet 3 har på sit ydre omfang tænder 7, hvilke tænder 7 muliggør en doseret udsåningsmængde af såsæd fra en ikke vist sædbeholder. Finsåningshjulet 3 sidder med et nav 8, der har en not 6 på såakslen 1. Endvidere har 15 finsåningshjulet 3 til begge sider altid en manchet lignende ansats 9, 10, der udvendigt altid har en vulstformet, omløbende låseforhøjning 11, 12.In the following, the sowing device is described predominantly by means of FIG. 2, with reference only occasionally to FIG. 1. The fine seed wheel 3 has on its outer extent teeth 7, which teeth 7 enable a dosed seed amount of seed from a seed container not shown. The fine sowing wheel 3 is fitted with a hub 8 having a groove 6 on the saw shaft 1. Furthermore, the fine sowing wheel 3 on both sides always has a cuff-like shoulder 9, 10, which externally always has a bead-shaped, circular locking elevation 11, 12.
På begge sider af finsåningshjulet 3 er der koaksialt på 20 såakslen 1 anbragt et normal såningshjul 13, 14, der altid har en manchetlignende ansats 15, 16 med en altid omløbende låsefordybning 17, 18. Normalsåningshjulene 13, 14 griber over finsåningshjulets 3 manchetlignende ansatser 9, 10 ind med disse ansatser 15, 16 og raster med låsefordybningerne 25 17, 18 ind på låseforhøjningerne 11, 12. Normalsåningshju lene 13, 14 har, præcis ligesom finsåningshjulet 3, knaster, for eksempel knasterne 19, 20, 21, 22. Disse knaster 19, 20, 21, 22 rager ud af en kappeoverflade 23 henholdsvis 24 på det respektive normal såningshjul 13, 14. Med hvert 30 normal såningshjul 13, 14 er en knast 20, 21 ikke fast for bundet med kappeoverfladerne 23, 24, med er derimod en del af et passtykke 25, 26.On both sides of the fine sowing wheel 3, a normal seed wheel 13, 14 is provided coaxially on the 20 saw shaft 1, which always has a cuff-like groove 15, 16 with an always-round locking recess 17, 18. The normal sowing wheels 13, 14 engage the cuff-like groove 9 of the fine sowing wheel 3. , 10 with these abutments 15, 16 and with the recesses 25 17, 18 and with the recesses 11, 12. The normal sowing wheels 13, 14 have, just like the fine sowing wheel 3, crushes, for example the lugs 19, 20, 21, 22. These bosses 19, 20, 21, 22 protrude from a casing surface 23 and 24, respectively, on the respective normal sowing wheel 13, 14. With each 30 normal sowing wheels 13, 14, a cam 20, 21 is not fixed too tightly with the casing surfaces 23, 24, with is, on the other hand, part of a passport 25, 26.
Den nøjagtige udformning af et passtykke 25, 26 kan ses på 35 fig. 3 og 4. Passtykket 25 og tilsvarende naturligvis også det ligesådan udformede passtykke 26 har et føringsstykke DK 169160 B1 6 27, som har en bueformet krumning og passer nøje mellem kappeoverfladen 24 og ansatsen 15 på normalsåningshjulet 14. På føringsstykket 27 er der anbragt en føringsliste 28, som bærer en knast 20 og ved hjælp af en slids 33, som er 5 vist i fig. 1, formår at gribe ind i kappeoverfladen 24. På begge forsider har føringsstykket 27 et i tværsnit omtrent retvinklet fremspring 29, 30, der er overordentlig betydningsfuld for såindretningens funktion.The exact design of a passport piece 25, 26 can be seen in FIG. 3 and 4. The fitting piece 25 and, of course, the similarly fit piece 26 also has a guide piece DK 169160 B1 6 27, which has an arcuate curvature and fits closely between the casing surface 24 and the shoulder 15 on the normal sawing wheel 14. A guide strip is arranged on the guide piece 27 28 carrying a cam 20 and by means of a slot 33 shown in FIG. 1, manages to engage the sheath surface 24. On both sides, the guide piece 27 has a cross-sectional projection 29, 30 which is extremely angular, which is extremely important for the operation of the sowing device.
10 Passtykket 25 rager, som det kan ses på fig. 2, i den viste position med sit fremspring 29 ind i en udsparing 31 på såhuset 2. Normalsåningshjulet 14 er derved fast forbundet med såhuset 2, så det ikke kan dreje sig. Skubber man passtykket 25 til venstre i forhold til tegningen, formår det, 15 når finsåningshjulet 3 befinder sig i den rigtige stilling, med sit fremspring 30 at gribe ind med en udsparing på finsåningshjulet 3. En sådan stilling, i hvilken normalsåningshjulet 14 er sammenkoblet med finsåningshjulet 3, er vist for passtykket 26. Det kan ses på venstre underste 20 billeddel i fig. 2, at passtykket 26 griber ind i en udsparing 32 på finsåningshjulet 3 og ikke længere i en udsparing på såhuset 2. Derved drejer normalsåningshjulet 13 sig synkront med finsåningshjulet 3.10 The fitting piece 25 protrudes, as can be seen in FIG. 2, in the shown position with its projection 29 into a recess 31 on the seed housing 2. The normal sowing wheel 14 is thereby firmly connected to the seed housing 2 so that it cannot rotate. If the passport 25 is pushed to the left relative to the drawing, it is able 15, when the fine sowing wheel 3 is in the correct position, to engage its projection 30 with a recess on the fine sowing wheel 3. Such a position in which the normal sowing wheel 14 is coupled to the The fine-cutting wheel 3 is shown for the pass piece 26. It can be seen on the left lower 20 image part of FIG. 2, that the fitting piece 26 engages in a recess 32 on the fine sowing wheel 3 and no longer in a recess on the seed housing 2. The normal sowing wheel 13 rotates synchronously with the fine sowing wheel 3.
25 På fig. 1 vises to udsparinger 32, 32' med skravering, der står i en vinkel på ca. 45° i forhold til hinanden. For at finde den rigtige stilling til koblingsproceduren, kan de forskydelige knaster 20, 21 mærkes med farver. Endvidere kan det anbefales at anbringe en markering på finsånings-30 hjulet 3 mellem de to udsparinger 32, 32' for at kunne bringe dets udsparinger 32, 32' i den rigtige stilling i forhold til passtykkerne 25, 26. Når udsparingerne 32, 32' ikke mere er anbragt i forhold til hinanden med 90°, kan man bagfra uden samtidigt at dreje såakslen 1 forskyde beg-35 ge knaster 20, 21 og dermed koble de to normal såningshjul 13, 14.25 In FIG. 1 shows two recesses 32, 32 'with shading which stand at an angle of approx. 45 ° relative to each other. To find the correct position for the coupling procedure, the sliding knobs 20, 21 can be marked with colors. Furthermore, it is recommended to place a mark on the fine-cut wheel 3 between the two recesses 32, 32 'in order to bring its recesses 32, 32' in the correct position relative to the pass pieces 25, 26. When the recesses 32, 32 ' is no longer positioned relative to one another by 90 °, from behind it is possible to displace both bosses 20, 21 at the same time without simultaneously rotating the seed shaft 1 and thus coupling the two normal sowing wheels 13, 14.

For at fiksere passtykkerne 25, 26 i deres to stillinger opviser de på føringsdelens 27 underside altid to aksialt efter hinanden anbragte låsefordybninger 34, 35 (fig. 2).In order to fix the pass pieces 25, 26 in their two positions, they always exhibit on the underside of the guide part 27 two axially arranged recesses 34, 35 (Fig. 2).
5 En trykfjeder 36 er anbragt i en radial boring 37 på normalsåningshjulet 13 henholdsvis 14 og trykker en kugle 38 radialt udad, så den alt efter passtykkets 25 henholdsvis 26 stilling sidder i den ene eller den anden låsefordybning 34, 35. Mellem låsefordybningerne 34, 35 er der anbragt et 10 trin 39, der opviser en relativt ringe højde, så passtykkerne 25, 26 relativt let kan skubbes fra den ene låsestilling ind i den anden.5 A compression spring 36 is arranged in a radial bore 37 on the normal sowing wheel 13 and 14, respectively, and pushes a ball 38 radially outwards, depending on the position of the fitting 25 and 26 respectively, in one or the other recesses 34, 35. Between the lock recesses 34, 35 For example, a step 39 is provided which exhibits a relatively low height so that the pass pieces 25, 26 can be pushed relatively easily from one locking position into the other.
