Opfindelsen angår en indretning til en udbringningsmaskine, der benyttes indenfor landbruget, såsom en maskine til udbringning af såsæd, gødning i fast eller flydende form eller lignende materialer, uden at jorden først er blevet bearbejdet 5 ved pløjning, harvning eller på anden måde bearbejdet, hvilken maskine omfatter en ramme eller et chassis, bærehjul, som kan svinges nedad og opad i forhold til rammen ved hjælp af et kraftorgan, udbringningsskær, som er forsynet ned udbringningsmundstykker, og som er anbragt på den nedre bageste ende 10 af skærarme, samt gummielastisk fjedrende fastgørelseselementer, der drejeligt forbinder skærarmenes øvre forreste ende med rammen med henblik på at muliggøre en begrænset vertikal svingende bevægelse af udbringningsskærene.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a device for an agricultural machine used in agriculture, such as a machine for the application of seed, fertilizer in solid or liquid form or similar materials, without the soil being first worked by plowing, harrowing or otherwise worked, which machine comprises a frame or chassis, carrier wheels which can be pivoted downwardly and upwardly relative to the frame by means of a power means, application cutters provided with delivery nozzles and mounted on the lower rear end 10 of cutting arms, and rubber elastic spring fasteners that pivotally connect the upper front end of the cutting arms to the frame to allow for limited vertical oscillating movement of the cutting inserts.
Der kendes indretninger, hvor indstillingen af arbejdsdybden, 15 f.eks. i maskiner til udbringning af såsæd i den ønskede sådybde, sker med udgangspunkt i på hver side af redskabet anbragte bære- og transporthjul, eller med udgangspunkt i ved en såmaskines bagerste del anbragte bærehjul.Devices are known in which the setting of the working depth, e.g. in machines for applying seed at the desired seed depth, is carried out on the supporting and transport wheels arranged on each side of the implement, or on the basis of bearing wheels placed at the rear part of a seed drill.
Det er klart, at der ved indstillingen af arbejds- eller så-20 dybden med udgangspunkt i kun to hjul, ikke kan tages hensyn til ujævnheder i marken mellem de nævnte hjul. Arbejdsdybden vil derfor variere kraftigt i afhængighed af ujævnheder på marken. Nøjagtigheden af indstillingen af arbejdsdybden kan varieres væsentligt, hvis der benyttes flere støtte- eller 25 bærehjul som referencepunkter, men selv herved kan dybden variere meget. F.eks. ved såning, hvor en sådybde på 20 til 40 mm., er almindelig, er det nødvendigt at anbringe såsæden indenfor nogle få mm. af den korrekte sådybde for, at opnå et godt resultat.Obviously, when adjusting the working or sowing depth based on only two wheels, unevenness in the field between said wheels cannot be taken into account. Depth of work will therefore vary widely depending on unevenness in the field. The accuracy of the adjustment of the working depth can be considerably varied if more support or support wheels are used as reference points, but even in this the depth can vary widely. For example. For sowing where a sowing depth of 20 to 40 mm is common, it is necessary to place the seed within a few mm. of the correct seed depth to achieve a good result.
30 Ved kendte maskiner, er der normalt anbragt to transporthjul udenfor den bredde, der dækkes af skærene, hvilket dels fremkalder et højt hjultryk og dels forøger såmaskinens bredde udover den nødvendige såbredde.30 In the case of known machines, two transport wheels are usually placed outside the width covered by the cutters, which partly induces a high wheel pressure and partly increases the width of the seed drill in addition to the required seed width.
2 DK 169636 B12 DK 169636 B1
Skærene på kendte udbringningsmaskiner er fast forbundne med en ramme ved hjælp af stive arme. Rammen strækker sig over maskinens fulde bredde, hvilket bevirker, at såfremt et skær støder mod en forhindring på marken f.eks. en sten, vil dette 5 skær blive udsat for meget store kræfter, såfremt den er stift fastgjort. Skærene er derfor anbragt vertikalt drejeligt på en horisontal akseltap, og gjort affjedrende ved hjælp af f.eks. en skruefjeder af fjederstål. En sådan konstruktion er udsat for stort slid på grund af urenheder. Selvom de bevægelige de-10 le bliver smurt, vil sliddet være stort, og der vil opstå slør, således at skærene ikke bliver bevæget langs de tilsigtede baner.The inserts of known application machines are firmly connected to a frame by means of rigid arms. The frame extends over the full width of the machine, which means that if a cutter encounters an obstacle in the field e.g. a stone, this 5 inserts will be subjected to very large forces, if it is rigidly attached. The cutters are therefore arranged vertically pivotally on a horizontal shaft pin, and made resilient by e.g. a spring steel screw spring. Such a construction is subject to great wear due to impurities. Although the moving parts are lubricated, the wear will be large and blurs will occur so that the inserts are not moved along the intended webs.
Formålet med opfindelsen er at anvise en indretning til en udbringningsmaskine af den indledningsvis nævnte art, som af-15 hjælper ovennævnte ulemper.The object of the invention is to provide a device for a delivery machine of the kind mentioned above, which alleviates the above-mentioned disadvantages.
Til opnåelse af dette formål er indretningen ifølge opfindelsen ejendommelig ved de i krav l's kendetegnende del anførte træk.For the purpose of this purpose, the device according to the invention is characterized by the features of claim 1.
Ved at hvert bærehjul ved hjælp af indstillingsorganets på-20 virkningsorganer styrer et par skiveskær i hver række af skær opnås en meget nøjagtig styring af skiveskærenes arbejdsdybde og dermed af sådybden i hele maskinens arbejdsbredde.By controlling each support wheel by means of the actuating means of the adjusting means, a pair of disc inserts in each row of inserts provides a very accurate control of the working depth of the disc inserts and thus of the sowing depth throughout the working width of the machine.

I fig. 1 betegner henvisningstallet 1 en såmaskine i sin helhed. Henvisningstallet 2 betegner maskinens chassis eller ram-10 me. Henvisningstallet 3 angiver bærehjulene, og henvisningstallet 4 et forreste såskær i form af en roterende skive og henvisningstallet 5 et bagerste såskær. Disse skær er forbundet med bærehjulet 3 på en måde, som vil blive beskrevet nedenfor.In FIG. 1, the reference numeral 1 denotes a drill as a whole. Reference numeral 2 denotes the machine's chassis or frame. Reference numeral 3 denotes the carrier wheels, and reference numeral 4 a front seed insert in the form of a rotating disk and reference numeral 5 a rear seed insert. These inserts are connected to the carrier wheel 3 in a manner as will be described below.
15 På såmaskinens 1 chassis 2, er der anbragt mindst en hydrau- . lisk cylinder 6. Denne cylinder kan dreje en aksel, der strækker sig på tværs af hele maskinen og har for hvert bærehjul 3 en arm 7, hvis ydre ende er forsynet med et drej eled 24 for bærehjulsarmene 8, der er anbragt på hver side af bærehjulene 20 3. Den nedre ende af armene 8 er drejeligt forbundet med bære hjulenes 3 bærehjulsaksler 9.At least one hydraulic is arranged on the chassis 2 of the seed drill 1. This cylinder can rotate a shaft extending across the entire machine and has for each carrier wheel 3 an arm 7, the outer end of which is provided with a pivot joint 24 for the carrier arms 8 arranged on each side of bearing wheels 20 3. The lower end of the arms 8 is pivotally connected to the bearing wheels 9 of the wheels 3.
I Fig. 2 er der for de enkelte dele benyttet samme henvisningstal, som i fig. 1. En balanceaksel 10 forløber gennem bærehjulets 3 center, og kan eventuelt udgøres af bærehjuls-25 akslen, idet balanceakslen da er forsynet med balancearme 11 og 12 på hver side af armene 8. Ved den ydre ende af balancearmene 11 og 12 er der anbragt stænger 13 og 14, som er drejeligt forbundet med de ydre ender af balancearmene 11 og 12.In FIG. 2, the same reference numerals as in FIG. 1. A balance shaft 10 extends through the center of the carrier 3 and may be constituted by the carrier 25 shaft, the balance shaft being then provided with balance arms 11 and 12 on each side of the arms 8. At the outer end of the balance arms 11 and 12 bars 13 and 14 which are pivotally connected to the outer ends of the balance arms 11 and 12.
De andre ender af disse stænger er drejeligt forbundet med 30 skiveskærenes 4 og 5 skiveaksler 15 og 16.The other ends of these rods are pivotally connected to the disc shafts 15 and 16 of the discs 4 and 5.
4 DK 169636 B14 DK 169636 B1
Fig. 2 viser yderligere skærarme 17 og 18 for skiveakslerne 15 og 16. Fastgørelsesenderne af disse arme er forbundet med såmaskinens 1 chassis 2 ved hjælp af gummielastisk fjedrende fastgørelseselementer 19 og 20. Ved en given indstilling af 5 armen 7 ved hjælp af den hydrauliske cylinder 6 bliver armens ydre drejepunkt 24 og derved bærehjulsarmens 8 øvre drejepunkt 24 fastholdt i forhold til chassiset 2. Når maskinen bevæger sig fremad, vil skiveskærene tilvejebringe furer på marken. Disse furer har en dybde, som er betegnet med henvisningstal-10 let 21, og såsæden anbringes i bunden af disse, ved hjælp af mundstykkerne 22.FIG. 2 further shows cutting arms 17 and 18 for the disc shafts 15 and 16. The fastening ends of these arms are connected to the chassis 2 of the drill 1 by means of rubber elastic resilient fasteners 19 and 20. At a given setting of the arm 7 by means of the hydraulic cylinder 6, the outer pivot point 24 of the arm and thereby the upper pivot point 24 of the carrier arm 8 maintained relative to the chassis 2. As the machine moves forward, the discs will provide grooves in the field. These grooves have a depth designated by the reference numeral 21 and the seed is placed at the bottom thereof by means of the nozzles 22.
Fig. 2 viser maskinens funktion, når den arbejder på en jævn ensartet mark, og maskinen bevæger sig i pilens 23 retning. Figuren viser ligeledes funktionen af indretning, når det for-15 reste såskær 4 møder et hårdt område 30 eller en sten i marken, hvorved skærets 4 arm 17 da i modsat retning af urets omløbsretning svinger bagud og opad i pilens 32 retning. Dette resulterer i, at stangen 13 bevæges bagud og påvirker balancearmen 11, således at bærehjulet 3 også i modsat retning af 20 urets omløbsretning bliver svinget noget bagud og opad i pilens 31 retning, idet det drejer omkring drejeleddet 24 ved armens 8 øvre ende. Ved denne bevægelse svinges også balancearmen 11 noget i modsat retning af urets omløbsretning, og skiveskærets 5 arm 18 bliver via stangen 14 nu i urets omløbs-25 retning svinget fremad og nedad i pilens 33 retning. De bevægelser, som balancearmene 11, 12 og stængerne 13, 14 udfører resulterer i, at dybden 21 af de furer, som skiveskærene 5 tilvejebringer, forbliver uændrede, når det andet såskær 4 af en eller anden årsag tvinges til at ændre sin højdeposition.FIG. 2 shows the operation of the machine as it operates on a smooth uniform field and the machine moves in the direction of arrow 23. The figure also shows the function of device when the first sowing cutter 4 encounters a hard area 30 or a stone in the field, whereby the arm 17 of the cutter 4 then swings backwards and upwards in the direction of the arrow 32 in the opposite direction. This results in the rod 13 moving backwards and influencing the balance arm 11, so that the carrier wheel 3 is also pivoted somewhat in the opposite direction of the clockwise rotation direction upwards and upwards in the direction of arrow 31 as it rotates around the pivot joint 24 at the upper end of the arm 8. In this movement, the balance arm 11 is also pivoted somewhat in the opposite direction of the clockwise direction, and the arm 18 of the disc cutter 5 is now pivoted forward and downward in the direction of the arrow 33 in the direction of the clock via the rod 14. The movements performed by the balance arms 11, 12 and the rods 13, 14 result in the depth 21 of the grooves provided by the discs 5 remaining unchanged when the second seed 4 for some reason is forced to change its height position.
30 Dette opnås ved et samspil mellem de ved hjælp af balancesystemet 13, 11, 10, 12, 14 med hinanden forbundne arme for akslerne 15, 9 og 16.This is achieved by an interaction between the arms connected by the balance system 13, 11, 10, 12, 14 to the shafts 15, 9 and 16.
Fig. 3 viser en anden udførelsesform for indretningen ifølge opfindelsen, hvor det af balancearme og stænger opbyggede ba-35 lancesystem mellem bærehjul og skiveskær, er udformet på en 5 DK 169636 B1 anden måde. De i figuren anførte henvisningstal angiver samme dele, som tidligere. Derudover angiver henvisningstallet 36 en fastgørelsesplade på 2 armen 8. Denne plade er forsynet med en række huller 37, i hvilket den ene ende af en stang 38 kan an-5 bringes drejeligt. Stangen 38 er forbundet med et fastgørelsespunkt 39 på en balancearm 40, hvis ene ende er drejeligt anbragt på skivens 5 aksel 16. Armen 40,s anden ende er forsynet med et drejepunkt 41 for en stang 42, der er forbundet med den forreste skives 4 aksel 15.FIG. 3 shows another embodiment of the device according to the invention, in which the balance system and balancing system between carrier wheels and discs is formed in a different way. The reference numerals shown in the figure indicate the same parts as before. In addition, the reference numeral 36 denotes a fastening plate on the 2 arm 8. This plate is provided with a series of holes 37 in which one end of a rod 38 can be pivotally mounted. The rod 38 is connected to a fastening point 39 on a balance arm 40, one end of which is pivotally mounted on the shaft 16. Of the disc 5, the other end of the arm 40 is provided with a pivot point 41 for a rod 42 connected to the front disc 4 shaft 15.
10 Når den forreste skive 4 ved denne udførelsesform for indretningen støder mod et hårdere område 30, vil armen 17 i modsat retning af urets omløbsretning svinge noget opad i pilens 32 retning, og stangen 42 vil blive bevæget bagud, som vist ved hjælp af pilen 43 og den øvre ende af armen 40 vil blive be-15 væget bagud, således at den nedre del af balancearmen 40 med skivens 5 aksel 16 vil svinge noget fremad, omkring drejepunk-tet 39. Herved vil også armen 8 via stangen 38 dreje lidt i modsat retning af urets omløbsretning, som vist ved hjælp af pilen 31. Akslerne 9, 15 og 16, der er forbundet med hinanden 20 ved hjælp af balancesystemet, vil således blive påført bevægelser på samme måde, som forud beskrevet under henvisning til figur 2, således at skiveskærets 5 arbejdsdybde forbliver i hovedsagen uændret. Såfremt skiven 5 møder en hårdhed, bliver bevægelserne i modsat retning af ovenfor.10 In this embodiment of the device, when the front disc 4 encounters a harder area 30, the arm 17 in the opposite direction of the clockwise direction will swing slightly upwards in the direction of the arrow 32 and the rod 42 will be moved backwards as shown by the arrow 43 and the upper end of the arm 40 will be moved backwards so that the lower portion of the balance arm 40 with the shaft 16 of the disc 5 will pivot somewhat forwardly, about the pivot point 39. Hereby, the arm 8 via the rod 38 will also pivot slightly in the opposite direction of the clockwise direction, as shown by arrow 31. Shafts 9, 15 and 16 connected to each other 20 by means of the balance system will thus be applied to movements in the same manner as previously described with reference to Figure 2, so that the working depth of the wafer 5 remains essentially unchanged. If the disc 5 encounters a hardness, the movements are in the opposite direction from above.
25 Normalt vil der ikke opstå så store afvigelser som beskrevet ovenfor, og systemet med balancearmene og stængerne, vil med små afvigelser arbejde omkring en middelstilling.25 Normally, no such large deviations will occur as described above, and the system of the balance arms and bars will work with small deviations around a mean position.
Det fremgår ligeledes af figur 3, at når bærehjulet 3 bevæger sig opad til et højere niveau, vil skærene 4 og 5 også bevæge 30 sig opad til et tilsvarende højere niveau, men dog stadig på en sådan måde, at arbejdsdybden 21 forbliver uforandret i forhold til bærehjulet 3.It can also be seen from Figure 3 that as the carrier 3 moves upward to a higher level, the blades 4 and 5 will also move upward to a correspondingly higher level, but still in such a way that the working depth 21 remains unchanged. to the carrier wheel 3.
Fremdeles fremgår det af figur 3, at såfremt vægten af maski- DK 169636 B1 6 nen vokser ved påfyldning af materiale eller ved belastning ved hjælp af balastvægte, vil skiveskærenes tryk på marken og deres evne til at trænge ned i jorden også vokse. I dette tilfælde svinger de normalt nedad og bagud forløbende arme 17, 5 18, 8 noget i modsat retning af urets omløbsretning, hvorved de gummielastisk fjedrende fastgørelseselementer 19 og 20 spændes.It is still evident from Figure 3 that if the weight of the machine grows when loading material or when loaded with ballast weights, the pressure of the discs on the field and their ability to penetrate the soil will also grow. In this case, the usually downwardly and rearwardly extending arms 17, 5, 18, 8 pivot somewhat in the opposite direction of the clockwise direction, thereby clamping the rubber elastic resilient fasteners 19 and 20.
Figur 4 viser sideværts op til hinanden liggende bærehjul, samt to furer 26, 25, der er tilvejebragt ved hjælp af det par 10 skiveskær, som hører til hvert bærehjul. I figuren ruller de viste bærehjul i forskellige højder i forhold til såmaskinen i sin helhed. Af det i det foregående omtalte fremgår det, at de forskellige bærehjul 13 styrer de med dem samhørende skær 4 og 5, således at dybden 21 af furerne 26 og 25 forbliver uændret 15 i forhold til hjulene, det vil sige, at bunden af furerne forbliver i en uændret dybde under den markoverflade, hvorpå bærehjulene 3 ruller.Figure 4 shows laterally adjacent bearing wheels, as well as two grooves 26, 25 provided by the pair of 10 cutting inserts belonging to each carrier wheel. In the figure, the shown wheels roll at different heights in relation to the drill as a whole. From the foregoing, it will be seen that the various carrier wheels 13 control the associated cutters 4 and 5, so that the depth 21 of the grooves 26 and 25 remains unchanged 15 relative to the wheels, that is, the bottom of the grooves remains at an unchanged depth below the field surface on which the carrier wheels 3 roll.
I figur 5 har bærehjulene 34 to rundtgående flanger 28 og 29, der er anbragt med samme indbyrdes afstand som furerne 26 og 20 25.1 figuren er forskydningen mellem flangerne 28 og 29 i for hold til såfurerne 26 og 25 angivet med henvisningstallet 27.In Figure 5, the carrier wheels 34 have two circumferential flanges 28 and 29 which are spaced apart from the grooves 26 and 20 25.1. In the figure, the displacement between the flanges 28 and 29 relative to the sappers 26 and 25 is indicated by the reference numeral 27.
Det er klart, at flangerne 28 og 29 vil presse såfurerne 26 og 25 sammen, ved at trykke på jorden og at sammentrykningen bliver kraftigere, jo mindre forskydningen 27 er.It is clear that the flanges 28 and 29 will compress the sappers 26 and 25 by pressing on the ground and that the compression becomes stronger, the smaller the displacement 27.
25 Figur 6 viser den situation, hvor forskydningen 27 er lig med nul, det vil sige flangerne 28 og 29 ruller lige over såfurerne 26 og 25 og presser disse sammen.Figure 6 shows the situation where the displacement 27 is equal to zero, that is, the flanges 28 and 29 roll right over the sappers 26 and 25 and compress them.
De beskrevne udførelsesformer for opfindelsen har vist maskiner med tre indbyrdes forbundne og højdeindstillelige aksler, 30 hvorpå der er anbragt drejelige bærehjul og skiveskær, som er forbundet med et balancesystem. Det er imidlertid klart, at flere end 3 enheder kan forbindes på tilsvarende måde med henblik på en udjævning af arbejdsdybden, styret af bære- eller DK 169636 B1 7 støttehjul. Således kan eksempelvis en såmaskine forsynes med tre i køreretningen i forskellig afstand anbragte skiveskær, idet to af akslerne er forsynet med balancearme, hvormed stænger til de to andre aksler er forbundet. Eksempelvis kan en 5 stang være drejeligt forbundet med bærehjulets lejring, medens to i forskellig afstand herfra anbragte aksler har balancearme, og den med bærehjulet forbundne stang er forbundet med den ene ende af det nærmest beliggende skiveskærs balancearm, medens den anden ende af denne balancearm er forbundet med den 10 ene ende af det næste skiveskærs balancearm, der ved dens anden ende er forbundet med det sidste skiveskærs aksel ved hjælp af en stang.The disclosed embodiments of the invention have shown machines with three interconnected and height adjustable shafts 30 on which rotatable carriers and discs are connected which are connected to a balance system. However, it is clear that more than 3 units can be connected in a similar manner for a leveling of working depth, controlled by support or support wheels. Thus, for example, a seed drill can be provided with three cutting discs spaced apart in the driving direction, two of the shafts being provided with balancing arms with which rods are connected to the other two shafts. For example, a 5 bar may be pivotally connected to the bearing wheel bearing, while two shafts located at different distances therefrom have balance arms, and the bar connected to the carrier wheel is connected to one end of the adjacent disc cutter balance arm while the other end of this balance arm is connected to the one end of the next disc shaving arm which at its other end is connected to the shaft of the last disc by means of a rod.
Ved den sidst beskrevne udførelsesform for balancesystemet er det hensigtsmæssigt, at tilpasse afstanden mellem balancearme-15 nes omdrejningspunkter - eller sagt på en anden måde balancearmenes udvekslingsforhold - således at de vertikale bevægelser bliver fordelt ligeligt på de forskellige aksler, i hovedsagen på samme måde, som man ved et hjulsystem med flere bogier fordeler bevægelserne ved hjælp af rammer, der forbinder 20 bogierne.In the last described embodiment of the balancing system, it is convenient to adjust the distance between the pivot points of the balance arms - or, in another way, the exchange ratio of the balance arms - so that the vertical movements are distributed equally on the various shafts, in the same manner as by a multi-bogie wheel system, the movements are distributed by means of frames connecting 20 bogies.
Balancearmene kan også have form som en trekantet plade. Således kan de i figur 3 viste balancearme 40 være udformet således, at drejepunkterne 16 og 41 befinder sig i samme position, som vist i figuren, medens drejepunktet 39 kan være forskudt 25 et stykke mod højre og anbragt i hjørnet af en trekantet plade.The balance arms can also take the form of a triangular plate. Thus, the balance arms 40 shown in Fig. 3 may be formed such that the pivot points 16 and 41 are in the same position as shown in the figure, while the pivot point 39 may be offset 25 a bit to the right and placed in the corner of a triangular plate.
Bærehjulet 3 kan også udgøres af en aflang med ribber forsynet rulle, som er anbragt på tværs af kørselsretningen. I dette tilfælde kan den nævnte rulle udgøre bærehjulet for 30 flere ved hjælp af stænger og balancearme forbundne enheder af den art, som eksempelvis er vist i figur 3.The carrier wheel 3 may also be constituted by an elongated rib, which is arranged transversely of the direction of travel. In this case, said roller may constitute the carrier for 30 more by means of rods and balance arms connected by units of the kind shown for example in Figure 3.
