Opfindelsen angår en gødningsspreder af den art, der er angivet i indledningen til krav 1.The invention relates to a fertilizer spreader of the kind specified in the preamble of claim 1.
Fra DE-OS 33 37 812 kendes et røreværk bestående af en navdel 5 og radialt udragende vinger, idet navet er fastgjort til en aksel, der roterer om en med spredeskivernes aksel sammenfaldende akse. Røreværket bringes til at rotere i samme retning som spredeskiven, men - ved indkobling af et reduktionsdrev - ved en væsentligt lavere omdrejningshastighed.DE-OS 33 37 812 discloses a stirrer consisting of a hub part 5 and radially projecting wings, the hub being fixed to a shaft rotating about an axis coinciding with the shaft of the spreading discs. The agitator is caused to rotate in the same direction as the spreading disc, but - when a reduction drive is engaged - at a substantially lower speed.

Det har vist sig, at et røreværk af denne art bevirker enten en sammenklæbning af den mineralgødning, der skal fordeles, på grund af rotation med en for høj hastighed, eller en ineffektiv omrøring af den gødning, der skal fordeles, i 15 den tragtformede udløbsåbning, så at der risiko for brodannelser.It has been found that a stirrer of this kind causes either an adhesion of the mineral fertilizer to be distributed due to rotation at too high a speed, or an inefficient stirring of the fertilizer to be distributed in the funnel-shaped outlet opening. so that there is a risk of bridging.
I DE-OS 20 58 782 er der beskrevet et røreværk, hvor en hvælvet skærm med større diameter er anbragt over rørevær-20 ket. Herved aflastes røreorganet fuldstændigt fra trykket i beholderen. I det ikke-trykaflastede område kan gødningsmidlet danne klumper, så at det ikke mere bliver transporteret.DE-OS 20 58 782 discloses a stirrer where a larger diameter vaulted screen is arranged over the stirrer 20. Hereby the stirrer is completely relieved from the pressure in the container. In the non-pressurized area, the fertilizer can form lumps so that it is no longer transported.
I så fald vil røreværket alene transportere det materiale, der befinder sig under skærmen.In this case, the agitator will only carry the material under the screen.

Det er på denne baggrund opfindelsens formål at anvise en gødningsspreder af den indledningsvis nævnte art, hvori røreværket er direkte forbundet med akselen uden noget indskudt hastighedsforøgende eller -formindskende drev, og som 30 sikrer en effektiv omrøring i tragtens udløbsåbning uden udvikling af så meget friktions varme, at den gødning, der skal fordeles, klæber sammen.Accordingly, it is the object of the invention to provide a fertilizer spreader of the kind mentioned above, in which the agitator is directly connected to the shaft without any inserted speed increasing or decreasing drive, and which ensures effective agitation in the outlet opening of the hopper without the development of so much friction heat. that the manure to be distributed is sticking together.
Dette formål opnås ved en gødningsspreder, som ifølge opfin-35 delsen udviser de træk, der er angivet i den kendetegnende del af krav l.This object is achieved by a fertilizer spreader which according to the invention exhibits the features defined in the characterizing part of claim 1.
DK 171944 B1 2 På grund af røreværkets ekscentriske lejring opnås en større effektiv arbejdsradius, så at hele den tragtformede udløbsåbning gennemrøres ved en enkelt omdrejning af nav-aksen om den faste akse. På grund af røreværkets kredsende bevægelse 5 om den faste akse bliver desuden risikoen for sammenklæbning betydeligt formindsket, eftersom røreværkets fingre kun i korte tidsrum berører den gødning, der skal fordeles.DK 171944 B1 2 Due to the eccentric bearing of the agitator, a greater effective working radius is obtained, so that the entire funnel-shaped outlet opening is stirred by a single rotation of the hub axis about the fixed axis. Furthermore, due to the stirring movement of the agitator 5 about the fixed axis, the risk of adhesion is significantly reduced, since the agitator's fingers only touch the fertilizer to be distributed for a short period of time.
På grund af den koniske skærm, der er anbragt over rørevær-10 ket, formindskes det nødvendige drejningsmoment til sikring af røreværkets rotation om den faste akse, idet trykket af gødningsmidlet oven for røreværket afledes og i stedet rettes under en skæv vinkel i forhold til den nævnte lodrette akse mod røreværkets sider. Dette er navnlig af betydning ved 15 igangsætning, idet det har vist sig, at der ved sammenklæbet eller sammenklumpet gødning kræves et større startmoment end hvad der kan opnås med sædvanlige traktorers hydrauliske drivorganer, når der ikke anvendes en skærm over røreværket.Due to the tapered screen positioned above the agitator, the necessary torque is reduced to ensure the agitation of the agitator about the fixed axis, deriving the pressure of the fertilizer above the agitator and directing it at an oblique angle to it. said vertical axis towards the sides of the agitator. This is particularly important at start-up, as it has been found that, when clamped or clumped, a greater starting torque is required than can be achieved with conventional tractor hydraulic drives when a screen over the agitator is not used.
20 Ved at omhylningskurven eller -fladen for fingrenes bevægelsesbane har en større diameter end skærmens afløbskant opnås, at fingrene løsner og fjerner kunstgødning fra området umiddelbart under skærmen.20 By having the wrapping curve or surface of the movement path of the fingers a larger diameter than the discharge edge of the screen, the fingers release and remove the fertilizer from the area immediately below the screen.
25 Det er navnlig af betydning, at røreværkets navdel er frit drejeligt lejret. Det har nemlig vist sig, at trykket fra det gødningsmiddel, der befinder sig i beholderen, udøver et sådant tryk mod fingrene, at navdelen herved bringes til at rotere med en passende lav hastighed i den modsatte ret-30 ning af den, hvori navdelens akse kredser om den faste akse.25 It is especially important that the stirrer hub portion is freely rotatably mounted. It has been found that the pressure of the fertilizer contained in the container exerts such pressure on the fingers that the hub portion is thereby rotated at a suitably low speed in the opposite direction to that in which the axis of the hub portion orbits the fixed axis.
Ved den i krav 2 omhandlede udførelsesform opnås mulighed for at indstille en efter kunstgødningens kornstørrelse og fugtindhold optimal afstand, således at der sker en stadig 35 udtømning af kunstgødning gennem beholderudløbet til spre-deskiven.In the embodiment according to claim 2, it is possible to set an optimum distance according to the grain size and moisture content of the fertilizer, so that a continuous discharge of artificial fertilizer takes place through the container outlet to the spreading disc.
3 DK 171944 B13 DK 171944 B1
Ved den i krav 3 omhandlede udførelsesform opnås mulighed for en effektiv omrøring i området umiddelbart ved udtømningsåbningen under en i forhold til røreeffekten minimal modstand med heraf følgende ringe varmeudvikling.In the embodiment according to claim 3, an effective agitation is achieved in the area immediately at the discharge opening under a minimal resistance to the stirring effect, with the resultant poor heat generation.
55
Ved den i krav 4 omhandlede udføre Ises form sikres en relativ høj omdrejningshastighed for røreværket omkring navdelens akse, idet den aerodynamiske forkant vil reducere modstanden mod fremdrivningen gennem gødningsmaterialet, samtidig med 10 at trykket fra gødningsmaterialet i beholderen får fuld virkning på den flade bagkant.In the form of the embodiment of claim 4, a relatively high rotational speed of the agitator is ensured around the axis of the hub part, the aerodynamic leading edge reducing the resistance to propulsion through the fertilizer material, while at the same time giving the pressure of the fertilizer material in the container full effect on the flat rear edge.
Ved den i fig. 5 omhandlede udførelsesform opnås en yderst effektiv omrøring med overskæring af eventuelle klumpdannel-15 ser i gødningsmaterialet.In the embodiment shown in FIG. 5, a highly effective agitation is obtained by cutting any clumps in the fertilizer material.
Ved den i krav 6 omhandlede udførelsesform opnås en særlig hensigtsmæssig omrøring i området under skærmen.In the embodiment according to claim 6, a particularly convenient agitation is achieved in the area under the screen.
20 Ved en i praksis foretrukken udførelsesform, omhandlet i krav 7, er der opnået tilfredsstillende omdrejningstal og jævn udstrømning gennem udtømningsåbningen ved et afstandsinterval på fra 5 til 15 mm mellem den faste omdrejningsakse og navdelens omdrejningsakse.In a preferred embodiment of claim 7, satisfactory rpm and smooth flow through the discharge opening are obtained at a distance of 5 to 15 mm between the fixed axis of rotation and the axis of rotation of the hub portion.

Opfindelsen skal i det følgende forklares nærmere under henvisning til det på tegningen viste udførelseseksempel på en gødningsspreder ifølge opfindelsen, hvoraf kun de til forståelse af opfindelsen nødvendige dele er vist, idet 30 fig. 1 viser et røreværk placeret i bunden af en stelbåret beholder, fig. 2 og 3 det i fig. 1 viste røreværk, set fra siden hen-35 holdsvis fra oven, DK 171944 B1 4 fig. 4 og 5 et røreværk med en ændret udformning, set fra siden henholdsvis fra oven, og fig. 6 viser en til røreværket hørende finger.The invention will be explained in more detail below with reference to the exemplary embodiment of a fertilizer spreader according to the invention, of which only the parts necessary for understanding the invention are shown, with figs. 1 shows a stirrer located at the bottom of a rigid container; FIG. 2 and 3, the FIG. 1, seen from the side, respectively, from above, DK 171944 B1 4 fig. 4 and 5 are a side view, respectively, of a stirrer having a modified design, and FIG. 6 shows a stirring finger.
5 I fig. 1 er der til illustration af opfindelsesområdet vist en konventionel, kegleformet beholder 1, som via et rørstel 10 er indrettet til montering, f.eks. på en traktor. Beholderen 1 indeholder pulverformet eller granuleret kunst-10 gødning 13. I bunden af det tragtformede udløb 2 er der tilvejebragt en udtømningsåbning 8 for det til udstrømning bestemte materiale. Fra udtømningsåbningen 8 afgives materialet til en spredeskive 3, der fremdrives i rotation ved sammenkobling med f.eks. traktorens kraftudtag. I det tragt-15 formede udløb 2 er der anbragt et røreværk 30, der skal beskrives nærmere i det følgende. Over røreværket 30 er der anbragt en tragtformet skærm 31 med åbningen vendende ned mod røreværket.5 In FIG. 1, a conventional cone-shaped container 1 is shown illustrated by means of a pipe frame 10 for mounting, e.g. on a tractor. Container 1 contains powdered or granulated artificial fertilizer 13. At the bottom of the funnel-shaped outlet 2, a discharge opening 8 is provided for the material intended for discharge. From the discharge opening 8, the material is delivered to a spreading disc 3 which is propelled in rotation by coupling with e.g. tractor power take-off. In the funnel-shaped outlet 2 there is arranged a stirrer 30, to be described in more detail below. Above the agitator 30 is a funnel-shaped screen 31 with the aperture facing down towards the agitator.
20 Det i fig. 2 og 3 viste røreværk 30 består af en central navdel 4, hvortil der er fastgjort radialt udad og ned-adragende fingre 5. Ved den på tegningen viste udførelsesform er der tilvejebragt i alt seks fingre. Navdelen 4 er indrettet til at rotere frit omkring en lejetap 6. Ved en 25 praktisk udførelsesform er navdelen 4 lejret i et konventionelt kugleleje af aksialtypen.20 The FIG. The agitator 30 shown in Figures 2 and 3 consists of a central hub portion 4 to which radially outward and downwardly projecting fingers 5. are attached. In the embodiment shown in the drawing, a total of six fingers are provided. The hub portion 4 is arranged to rotate freely around a bearing pin 6. In a practical embodiment, the hub portion 4 is housed in a conventional axial type ball bearing.
Lejetappen 6 er fast forbundet med drejeskiveakselen 7 og placeret i en afstand e herfra. Ved tom beholder vil akse-30 len 7's rotation medføre, at akseltappen 6 føres i en cirkelbevægelse omkring akselen 7, og navdelen 4 med fingrene 5 føres med i denne bevægelse uden at rotere omkring lejetappen 6. Når der derimod er gødningsmateriale 13 i beholderen 1 vil trykket herfra give anledning til en rotation 35 af navdelen 4 med fingre 5 omkring lejetappen 6 og modsat akselen 7's omdrejningsretning, således som det er antydet ved pilene i fig. 1.The bearing pin 6 is firmly connected to the turntable shaft 7 and located at a distance e from it. In the case of an empty container, the rotation of the shaft 7 will cause the shaft pin 6 to move in a circular motion around the shaft 7, and the hub portion 4 with the fingers 5 will move in that movement without rotating around the bearing pin 6. On the other hand, there is fertilizer material 13 in the container 1. the pressure therefrom will give rise to a rotation 35 of the hub portion 4 with fingers 5 around the bearing pin 6 and opposite to the direction of rotation of the shaft 7, as indicated by the arrows in FIG. First

Den i fig. 4 og 5 viste udførelsesform for et røreværk ifølge opfindelsen svarer til den i fig. 2 og 3 viste udførelsesform/ idet fingrene dog har forskellig form. Ved udførelsesformen ifølge fig. 4 og 5 er hveranden finger 5' 5 udformet med et retliniet forløb fra navdelen og skråt ned mod beholderbunden. Forsøg har vist, at denne kombination af krumme fingre 5 og retliniede fingre 5' giver en særlig hensigtsmæssig omrøring i området under skærmen 31.The FIG. 4 and 5, a stirrer according to the invention is similar to that of FIG. 2 and 3, however, the fingers having different shapes. In the embodiment of FIG. 4 and 5, each other finger 5 '5 is formed with a straight line from the hub portion and inclined downwardly towards the container bottom. Tests have shown that this combination of curved fingers 5 and rectilinear fingers 5 'provides a particularly convenient stirring in the area below the screen 31.
10 For at forøge virkningen af det omdrejningsmoment, der ved akselen 7's rotation påføres føreværket 30, kan fingrene 5 være udformet som vist i fig. 6, dvs. med en nedre del 9, som i tværsnit er trekantet og med sin spidse del pegende fremad i bevægelsesretningen.10 In order to increase the effect of the torque applied to the feed 30 by rotation of the shaft 7, the fingers 5 may be formed as shown in FIG. 6, i.e. with a lower portion 9 which is triangular in cross section and with its pointed portion pointing forward in the direction of movement.

Opfindelsen er ikke begrænset til netop de viste og beskrevne træk. Røreværket kan således være udformet med færre eller flere fingre end de seks fingre, der er vist på tegningen, og fingre med forskellig udformning kan være 20 kombineret på forskellig måde. Skærmen over røreværket kan ligeledes være anderledes udformet, og det ville f.eks. være muligt at gøre brug af en halv kugleskal.The invention is not limited to precisely the features shown and described. Thus, the agitator may be formed with fewer or more fingers than the six fingers shown in the drawing, and fingers of different designs may be combined in different ways. The screen above the agitator can also be designed differently, for example. be able to make use of a half ball shell.
