Description

i DK 172730 B1 DATASTYRET FODERVOGN TIL KVÆG Teknikkens standpunkt 5 Opfindelsen angår en datastyret fodervogn af den i krav l's indledning angivne art.The invention relates to a computerized feed truck of the kind specified in the preamble of claim 1.

En sådan fodervogn til et fuldautomatisk, datamatstyret fodringsanlæg er kendt fra ansøgerens allerede markedsførte 10 produkt, der markedsføres under typebetegnelsen M 2000 Smart Feeder grovfodervogn. Fodervognen rummer de foderkomponenter i tør eller flydende form, som der er behov for til fodring af kvæg. Fodervognen kører på en i loftet ophængt skinne, som følger det eller de foderborde eller det 15 eller de fodertrug, hvortil køerne kommer frit, eller hvortil køerne er bundet til en fast ædeplads. Fodervognen styres ved en datamat, hvori hvert enkelt dyr eller hver gruppe af dyrs daglige foderforbrug samt andre oplysninger er indprogrammeret. Fodervognen stopper automatisk ud for 20 hvert dyr og udvejer en nøjagtig portion af de forskellige foderkomponenter, alt styret af datamaten. Foderet kan f.eks. bestå af snittet majs- eller græsensilage (såkaldt grovfoder) i ét rum i fodervognen og kraftfoder i andre rum samt fodertilskudsblandinger såsom mineral- eller vitamin-25 blandinger i endnu andre rum. Alle foderkomponenterne doseres enkeltvis til en vejeenhed, der afvejer og tarerer mellem hver udvejning. Vejeenheden omfatter et i forhold til fodervognens længdeakse tværgående transportaggregat, f.eks. et transportbånd, der udfodrer de afvejede foderkom-30 ponenter, når afvejningerne er afsluttet. Ved udlevering af foderet sker en vis beskeden blanding af de enkelte foderkomponenter.Such a feed trolley for a fully automatic, computer-controlled feeding plant is known from the applicant's already marketed 10 product marketed under the type designation M 2000 Smart Feeder coarse feed trolley. The feed cart contains the feed components in dry or liquid form that are needed for feeding cattle. The feed trolley runs on a rail suspended in the ceiling, which follows the feed table (s) or feed trough (s) to which the cows come freely or to which the cows are tied to a fixed eating place. The feed cart is controlled by a computer in which each animal or group of animals' daily feed consumption as well as other information is programmed. The feed truck automatically stops for 20 animals and weighs an exact portion of the various feed components, all controlled by the computer. The feed may e.g. consist of cut corn or grass silage (so-called coarse fodder) in one compartment of the forage wagon and concentrate feed in other compartments, as well as feed supplement mixtures such as mineral or vitamin 25 mixtures in still other compartments. All the feed components are individually dosed into a weighing unit that weighs and tares between each weighing. The weighing unit comprises a transverse conveying unit in relation to the longitudinal axis of the feed trolley, e.g. a conveyor belt which feeds the weighed feed components when the weights are completed. Upon delivery of the feed, some modest mixing of the individual feed components occurs.

For at optimere kødproduktion og mælkeydelse fra kvæg er 35 det nødvendigt at fodre hvert dyr, eller hver gruppe af dyr med en individuel og optimal blanding af nærings- og struk- 2 DK 172730 B1 turstoffer, der er afpasset efter det enkelte dyrs race, alder og tidsmæssige placering i laktationsperioden.In order to optimize meat production and milk yield from cattle, it is necessary to feed each animal, or each group of animals, with an individual and optimal mixture of nutrients and structures adapted to the breed, age of the individual animal. and temporal placement during the lactation period.

Det er en kendt sag, at en sammenblanding af foderkomponen-5 terne til en vis grad af homogenitet, så dyrene ikke kan separere de enkelte foderkomponenter og kun æde de dele, de har mest lyst til at æde, har en stor positiv indflydelse på dyrenes helbred og produktion.It is a known case that mixing together the feed components to a certain degree of homogeneity so that the animals cannot separate the individual feed components and eat only the parts they most want to eat has a great positive influence on the animals. health and production.

10 Med ansøgerens grovfodervogn M 2000 sker der ikke nogen egentlig blanding af foderkomponenterne under transport fra magasinerne, til de udfodres til foderbordet eller fodertruget. Der sker selvfølgelig en vis blanding af komponenterne under selve udleveringen, men denne blanding har i 15 praksis vist sig ikke at være tilstrækkelig.10 With the applicant's coarse feed trolley M 2000, there is no actual mixing of the feed components during transport from the magazines until they are fed to the feed table or feed trough. Of course, there is some mixing of the components during the actual delivery, but in practice this mixture has not proved to be sufficient.

Et alternativ til datastyrede fodervogne er anvendelse af en såkaldt foderblandevogn. I sådanne foderblandevogne kan alle foderkomponenterne blandes, men dette betyder, at alle 20 dyrene får samme fodersammensætning, eller i hvert fald at et større antal dyr får samme fodersammensætning, og nogle dyr bliver for fede på grund af en for kraftig kost og hermed forsinkes næste laktationsperiode. Anvendelsen af f.eks. traktortrukne foderblandevogne er desuden meget van-25 skelig at automatisere. Denne løsning er således i høj grad uhensigtsmæssig, men anvendes af praktiske årsager flere steder. Denne fodringsmetode kaldes i daglig tale TMR-fod-ring (Total Mixed Ration) og har bl.a. den fordel, at dyrerne får foderet blandet, så de ikke kan nøjes med at æde 30 de mest attraktive foderkomponenter.An alternative to computerized feed wagons is the use of a so-called feed mixer cart. In such feed mixer trucks, all the feed components can be mixed, but this means that all 20 animals will have the same feed composition, or at least a larger number of animals will have the same feed composition and some animals will become obese due to an excessive diet and thus delay next lactation period. The use of e.g. tractor-drawn feed mixer wagons are also very difficult to automate. This solution is thus highly inappropriate, but is used for practical reasons in several places. This feeding method is commonly referred to as the Total Mixed Ration (TMR) foot ring. The advantage is that the animals get the feed mixed so that they can not eat only 30 the most attractive feed components.

Fra USA patent nr. 5.069.155 kendes et udfodringssystem, hvor afmålingen af de enkelte foderkomponenter sker ved en tids-styring af de enkelte tilførselsorganer, der f.eks. er 35 tilførselssnegle, hvilket kun giver en tilnærmet rigtig sammensætning af foderet, idet der ikke sker en vejning af DK 172730 B1 3 de enkelte foderkomponenter. I fodersystemet indgår en datastyret fodervogn, hvor en vis blanding af foderkomponenterne opnås, ved at de enkelte komponenter ledes samtidig til en fælles transportsnegl, der giver en vis blanding af 5 komponenterne under udfodringen. Opblandingen er i øvrigt baseret på, at hovedkomponenten er ensilage, dvs. et grovfoderprodukt med forholdsvis stor fugtighedsindhold, således at de forskellige tilskuds-komponenter klæber hertil under udfodringen med en udfodringssnegl, og man opnår her-10 ved en vis sammenblanding af komponenterne. De enkelte komponenter tilføres udfodringssneglen direkte og på bestemte steder, hvilket er medvirkende til, at der kun opnås en beskeden sammenblanding af foderkomponenterne.From U.S. Patent No. 5,069,155, a feeding system is known in which the measurement of the individual feed components is done by timing the individual feeding means, e.g. is 35 feed augers, which only gives an approximate correct composition of the feed, since there is no weighing of the individual feed components. The feed system includes a data-controlled feed truck where a certain mixture of the feed components is obtained by simultaneously passing the individual components to a common transport auger, which gives a certain mixture of the 5 components during the feeding. The mixture is also based on the fact that the main component is silage, ie. a coarse feed product having a relatively high moisture content such that the various supplementary components adhere thereto during feeding with a feeding auger, and hereby a certain mixing of the components is obtained. The individual components are supplied to the feeding auger directly and in specific locations, which results in only a slight mixing of the feed components.

15 Fordele ved opfindelsenAdvantages of the Invention

Ved at udforme en datastyret fodervogn ifølge opfindelsen og som angivet i krav l's kendetegnende del får man en fodervogn, der kan fodre hvert enkelt dyr eller hver gruppe 20 af dyr individuelt og på en sådan måde, at den udfodrede foderblanding er en forholdsvis homogen blanding af nøje afvejede foderkomponenter. Blandingen er så effektiv, at dyrene ikke er i stand til at separere foderkomponenterne, og kun æde de dele, de har mest lyst til at æde. Ved en 25 konstant og sikker fodring med en præcis sammensætning og en tilstrækkelig sammenblanding af foderkomponterne, fås stærke og sunde dyr og en optimal produktion af kød og mælk.By designing a computerized feed cart according to the invention and as set forth in the characterizing part of claim 1, a feed cart is provided which can feed each individual animal or group of animals individually and in such a way that the fed compound feed is a relatively homogeneous mixture of carefully weighed feed components. The mixture is so effective that the animals are unable to separate the feed components and eat only the parts they most want to eat. By a constant and secure feeding with a precise composition and a sufficient mix of the feed components, strong and healthy animals and an optimal production of meat and milk are obtained.

30 Desuden opnår man mulighed for at indstille vognen afhængigt af hvilken type grovfoder, der anvendes således, at en optimal blanding af foderkomponenterne altid kan opnås.In addition, it is possible to adjust the trolley depending on the type of roughage used so that an optimal mixture of the feed components can always be obtained.

35 Ved at udforme fodervognen ifølge opfindelsen som anført i krav 2's og i krav 3's kendetegnende dele opnår man at re- 4 DK 172730 B1 ducere klemvirkningen mellem transportørsneglen og blande-huset, og man får også reduceret virkningerne af den indre friktion i grovfoderet, hvilket medfører, at energiforbruget til drivmotoren for transportsneglen reduceres, hvilket 5 har stor praktisk betydning, fordi fodervogne af den nævnte art sædvanligvis strømforsynes fra indbyggede akkumulatorer. Man får samtidig hermed på enkel måde en automatisering af sammenblandingen af foderkomponenter og en forøget sammenblandingsgrad, hvilket i øvrigt er vanskeligt, fordi 10 de forskellige komponenter jo findes i forskellige mængder og fordi de forskellige foderkomponenter har vidt forskellig struktur.By designing the feed trolley according to the invention as set forth in the characterizing parts of claim 2 and in claim 3, it is possible to reduce the clamping effect between the conveyor screw and the mixing housing and also reduce the effects of the internal friction in the roughage, which As a result, the energy consumption of the drive auger for the transport auger is reduced, which is of great practical importance because feed wagons of the aforementioned kind are usually supplied from built-in accumulators. At the same time, it is easy to automate the mixing of feed components and an increased degree of mixing, which is moreover difficult, because the different components are in different quantities and the different feed components have very different structure.

Bundklappen styres af datamaten, og man kan således via da-15 tamaten indstille kørselstiden for transportsneglen, der sammenblander delportionerne, inden bundklappen åbnes for udlevering af foderblandingen.The bottom flap is controlled by the computer, and it is thus possible through the computer to set the run time for the transport screw, which mixes the sub portions, before the bottom flap is opened for delivery of the feed mixture.

Ved at udforme fodervognen ifølge opfindelsen som anført i 20 krav 4's kendetegnende del får man reduceret transporten i tværgående retning, så der sker en større sammenblanding af de enkelte foderkomponenter inden disse udfodres.By designing the feed trolley according to the invention as stated in the characteristic part of claim 4, the transport is reduced in a transverse direction, so that a larger mixing of the individual feed components takes place before they are fed.

Fodervognen ifølge opfindelsen er fortrinsvis udformet som 25 anført i krav 5's kendetegnende del, idet dette har vist sig at være en velegnet dimensionering, når grovfoderet er snittet majs eller eventuelt græsensilage.The feed trolley according to the invention is preferably designed as indicated in the characterizing part of claim 5, since this has been found to be a suitable dimension when the roughage is cut corn or possibly grass silage.

Ved at udforme fodervognen ifølge opfindelsen som anført i 30 krav 6's kendetegnende del kan den på enkelt vis omstilles til forskellige grovfodertyper for opnåelse af optimal blanding.By designing the feed trolley according to the invention as set forth in the characterizing part of claim 6, it can easily be converted to different types of coarse fodder for optimum mixing.

Krav 7 angiver en anden udførelsesform for opfindelsen, 35 nemlig en ophængning af transportsneglen, som giver en god blanding, uden at drivmotoren trækker for meget strøm fra ! DK 172730 B1 5 batteriet, og hvor funktionen af transportsneglen er uafhængig af dens rotationsretning. Ved at ophænge transportsneglen ifølge opfindelsen og som anført i krav 8's kendetegnende del fås en fodervogn, hvori man også kan anvende 5 grovfoder, der er langsnittet og eventuelt klumpet i struk turen, uden at man får et stort strømforbrug i transportsneglens drivmotor.Claim 7 discloses another embodiment of the invention, namely a suspension auger, which provides a good mix without the drive motor drawing too much power! DK 172730 B1 5 and where the function of the transport screw is independent of its direction of rotation. By suspending the transport auger according to the invention and as stated in the characterizing part of claim 8, a forage wagon is obtained in which one can also use 5 coarse feed which is longitudinally cut and possibly clumped in the structure, without obtaining a large power consumption in the transport auger drive motor.

Ved yderligere at udforme fodervognen ifølge opfindelsen 10 som anført i krav 9's kendetegnende del får man allerede en vis sammenblanding af tilskudsfoderblandinger, kraftfoder m.v., når disse mindre portioner af foderkomponenter falder ned i blandehuset. Desuden fås en reduktion af det maksimale strømforbrug eller effektforbrug til drivmotorerne.By further designing the feed trolley according to the invention 10 as stated in the characterizing part of claim 9, a certain mixture of supplemental feed mixes, concentrates, etc., is already obtained when these smaller portions of feed components fall into the mixing housing. In addition, a reduction in the maximum power consumption or power consumption for the drive motors is obtained.

Beskrivelse af udførelseseksemplerneDescription of the Examples

Fig. 1-3 viser den datastyrede fodervogn 2 ifølge opfindelsen ophængt og kørende i en bæreskinne 1, f.eks. en I-for-30 met bæreskinne, hvor kørehjul fremføres på den I-formede skinnes nederste tværgående del. Fodervognen 2 er selvkørende, idet en strømforsyning (18), f.eks. et genopladeligt akkumulatorbatteri, leverer strøm til en ikke vist drivmotor, der trækker kørehjulene på skinnen 1. Kørslen styres 35 af en datamat 3 og et relæ- eller styreskab 19, som dels styrer kørslen og dels styrer selve fodervognens funktio- DK 172730 B1 7 ner. På eller ved skinnen 1 er der på kendt måde anbragt organer, der definerer stoppositioner, dvs. steder, hvor fodervognen 2 skal kunne standse og udlevere foderblandinger til dyr, enten ud fra positionsmæssige kriterier eller 5 ud fra aftastning af, hvilket dyr eller hvilken bås fodervognen er standset ved. Sådanne aftastnings- og identifikationssystemer er almindeligt kendte inden for området og skal derfor ikke forklares nærmere.FIG. 1-3 show the data controlled feed trolley 2 according to the invention suspended and running in a carrier rail 1, e.g. an I-for-30-foot support rail in which driving wheels are advanced on the lower transverse portion of the I-shaped rail. The feed trolley 2 is self-propelled, with a power supply (18), e.g. a rechargeable accumulator battery, supplies power to a drive motor not shown, which pulls the drive wheels on the rail 1. The drive is controlled 35 by a computer 3 and a relay or control cabinet 19, which partly controls the drive and partly controls the function of the feed truck itself. . On or at the rail 1, means are defined in known manner defining stopping positions, ie. places where the feed trolley 2 must be able to stop and deliver feed mixtures to animals, either on the basis of positional criteria or 5 on the basis of sensing of which animal or the stall the feed trolley is stopped at. Such sensing and identification systems are well known in the art and therefore need not be further explained.

10 Fodervognen 2 rummer de foderkomponenter i tør eller flydende form, der er behov til for fodring af kvæg, f.eks. malkekvæg. Fodervognen 2 har et antal foderrum. Foderrummet 3 4, der f.eks. er på 1,6 m , er indrettet til grovfoder, såsom snittet majs, græsensilage og lignende, der ved hjælp 15 af en transportør 9 og et antal fodervalser 10, 11 kan overføres til en husdel 20. På den modsatte side af husdelen 20 findes i det viste eksempel fire yderligere rum for foderkomponenter, nemlig rummene 5 og 6 for kraftfoder, hver af størrelsesordenen 65-185 1, og to mindre rum 7, 8 20 for fodertilskudsblandinger, såsom mineraler, vitaminer m.v. , hvilke rum er af størrelsesordenen 25 1. Foderkomponenter fra rummene 5, 6, 7, 8 doseres fra hvert rum ved hjælp af et transportorgan, f.eks. en motordreven snegl 12, 13, 14, 15, fra hvert rum til husdelen 20, som udgør et 25 indføringshus for indføring af foderkomponenter til et kombineret blande- og udleveringsorgan 16, 17, 29. Transportsneglene 12, 13, 14, 15 er trukket af hver sin elektromotor, som strømforsynes fra strømforsyningen 18.The feed trolley 2 contains the feed components in dry or liquid form needed for feeding cattle, e.g. dairy cattle. The feed trolley 2 has a number of feed compartments. The feeding room 3 4, which e.g. is 1.6 m, is designed for roughage, such as cut corn, grass silage and the like, which can be transferred to a housing part 20 by means of a conveyor 9 and a number of feed rolls 10, 11 on the opposite side of the housing part 20 In the example shown, four additional compartments for feed components, namely compartments 5 and 6 for concentrates, each of the order of 65-185 1, and two smaller compartments 7, 8 20 for feed supplement mixtures such as minerals, vitamins etc. which compartments are of the order 25 1. Feed components from compartments 5, 6, 7, 8 are dosed from each compartment by means of a transport means, e.g. a motor-driven auger 12, 13, 14, 15, from each compartment to the housing portion 20, which constitutes a feed housing for introducing feed components to a combined mixing and dispensing means 16, 17, 29. The transport augers 12, 13, 14, 15 are drawn. of each electric motor, which is powered from the power supply 18.

30 Alle foderkomponenter doseres til en vejeenhed 16 i bunden af husdelen 20 og som omfatter en transport- og blandesnegl 17 anbragt i et trugformet blandehus 29. Vejeenheden 16 af-vejer og tarerer mellem hver udvejning. Blandingen af foderkomponenter er således baseret på afvejning af delkompo-35 nenterne enkeltvis, men på en fælles vejeenhed, der automatisk, og styret af datamaten 3, tarerer mellem hver udvej- DK 172730 B1 8 ning.All feed components are dosed to a weighing unit 16 at the bottom of the housing portion 20 and comprising a conveying and mixing auger 17 arranged in a trough-shaped mixing housing 29. The weighing unit 16 weighs and tares between each weighing. The mixture of feed components is thus based on the weighing of the subcomponents individually, but on a common weighing unit which automatically and controlled by the computer 3 tares between each weighing unit.

Når delportionerne er sammenblandet eller samtidig med sammenblandingen, udfodres disse, styret af datamaten 3, såle-5 des, at hvert dyr får en optimal sammensætning og en afmålt mængde af de enkelte foderkomponenter. Herved får man et foderprincip eller fodersystem, som betegnes IMR (individual Mixed Ration), hvilket forklares nærmere i forbindelse med tegningens fig. 4-10.When the sub-portions are mixed together or at the same time as the mixing, these are fed, controlled by the computer 3, so that each animal receives an optimal composition and a measured amount of the individual feed components. This provides a feed principle or feed system, called IMR (individual Mixed Ration), which is explained in more detail in connection with the drawing of FIG. 4-10.

Tegningens fig. 4-10 viser detaljer i fodervognens blande-og udleveringsanordning, hvis position i fodervognen 2 er markeret på fig. 1. Indretningen af afvejnings- og blande-anordningen forklares herefter nærmere under henvisning til 15 fig. 4-6. Vejeanordningen 16 på fig. 1 ses detaljeret på fig. 4-5 og omfatter et aflangt og i fodervognen 2 tværstillet trug 29, hvori der er anbragt en blandesnegl 21 med en sneglevinding 24. Blandesneglen 21 er i hver ende lejret i et vinkelformet ophængningsorgan 23, hvilket ophængnings-20 organ kan svinges i lodret retning ved hjælp af hængsler 30. Sneglen 21 med drivmotorerne 22 er således ophængt forskydeligt i lodret retning og kan bevæges fra en position A til en position B, se fig. 4. På sneglen 21 er der en driv-motor i hver ende således, at de sammen kan trække sneglen 25 i samme rotationsretning, og begge motorer kan omstyres, afhængigt af i hvilken side udfodringen skal ske.FIG. 4-10 show details of the feeder mixer and dispensing device whose position in the feeder wagon 2 is marked in FIG. 1. The arrangement of the weighing and mixing device is then explained in more detail with reference to FIG. 4-6. The weighing device 16 in FIG. 1 is shown in detail in FIG. 4-5 and comprises an oblong and transverse trough 29 in the feed carriage 2, in which a mixing auger 21 is provided with a auger coil 24. The mixing auger 21 is mounted at each end in an angular suspension member 23, which suspension member may be pivoted in a vertical direction. by means of hinges 30. The auger 21 with the drive motors 22 is thus suspended slidably in the vertical direction and can be moved from a position A to a position B, see fig. 4. On the auger 21 there is a drive motor at each end so that they can pull the auger 25 in the same direction of rotation and both motors can be reversed, depending on which side the feeding is to take.

I hver ende af sneglen 21 kan den være forsynet med en udkastervinge 38, der befinder sig over en bundklap 33 i hver 30 side af truget 29. Hver bundklap 33 er hængslet til truget ved en hængsel 32, og bundklappen 33 kan manøvreres ved hjælp af en aktuator 34, f.eks. en elektrisk aktuator.At each end of the auger 21 it may be provided with an ejector blade 38 which is over a bottom flap 33 on each side 30 of the trough 29. Each bottom flap 33 is hinged to the trough by a hinge 32 and the bottom flap 33 can be actuated by an actuator 34, e.g. an electric actuator.

Truget 29 omfatter trugsider 36, der i forhold til sneglen 35 21 er opad- og udadvendende. Truget 29 har en bund 35, der i det væsentlige i tværsnit er cirkelbueformet, så det op- DK 172730 B1 9 advendende trug kan rumme sneglen 21 på en sådan måde, at der i hver side fremkommer et kanalområde 37, der på fig. 4 er vist tilspidset mod trugets bund, når sneglen er i position A, men som vil forløbe hele vejen under sneglen med i 5 det væsentlige ensartet lysning, hvis sneglen hæves til position B. Vinkelarmene 23 i hver ende af sneglen 21 er uafhængige af hinanden, så sneglen 21 kan udmærket hæves fra position A til B kun i den ene ende.Trough 29 comprises trough sides 36 which are upwardly and outwardly relative to the auger 35 21. The trough 29 has a bottom 35 which is substantially circular in cross-sectional shape, so that the advancing trough can accommodate the auger 21 in such a way that a channel area 37 is formed on each side, which in FIG. 4 is shown tapered to the bottom of the trough when the auger is in position A, but which will extend all the way under the auger with substantially uniform clearance if the auger is raised to position B. The angular arms 23 at each end of the auger 21 are independent of each other so that the auger 21 can be excellently raised from positions A to B only at one end.

10 Sneglen 21 er vist særskilt på fig. 6 og omfatter en sædvanlig sneglevinding 24, hvori der med mellemrum er gennemgående huller 25 for montering af yderligere omrøringsmidler, som kan bestå i en tværstillet bolt 26 med afstandsstykker 27. De udskiftelige bolte 26 og afstandsstykker 27, 15 der selvfølgelig kan monteres i forskellige dimensioner, giver mulighed for justering af blandesneglens 21 blande-virkning. Afstandsstykkerne 27 eller tilsvarende midler kan være udformet således, at de rager ud over sneglevindingens 24 periferi og kan i øvrigt være udformet med forskellige 20 former for fingre m.v., der hjælper med til at øge effekten af blandingen.10 The auger 21 is shown separately in FIG. 6 and comprises a conventional auger winding 24, in which there are at intervals through holes 25 for mounting additional agitators, which may consist of a transverse bolt 26 with spacers 27. The interchangeable bolts 26 and spacers 27, 15, of course, can be mounted in various dimensions. , allows adjustment of the mixing effect of the mixing screw 21. The spacers 27 or similar means may be formed so that they extend beyond the periphery of the auger winding 24 and may otherwise be formed with various 20 kinds of fingers, etc., which help to increase the effect of the mixture.

Under og fast i forbindelse med truget 29 er der anbragt en elektrisk vejecelle 31, hvis funktion og vejning styres af 25 datamaten 3.Below and fixed in connection with the trough 29, an electric weighing cell 31 is arranged, the function and weighing of which is controlled by the computer 3.

I forbindelse med tegningens fig. 7-8 forklares herefter funktionen af fodervognen ved fyldning af blande- og udleveringsanordningen samt, i forbindelse med fig. 9-10, blan-30 de- og udleveringsanordningen i funktion og under udfodring af en færdigblandet foderblanding.In connection with the drawing FIG. 7-8, the function of the feed trolley is then explained by filling the mixing and dispensing device and, in connection with fig. 9-10, the mixing and dispensing device in operation and during feeding of a pre-mixed feed mixture.

På fig. 7 ses, hvordan delportioner af kraftfoder 5a, 6a og delportioner af fodertilskud 7a, 8a er doseret i truget 29.In FIG. 7 shows how sub portions of concentrate feed 5a, 6a and sub portions of feed supplement 7a, 8a are dosed in the trough 29.

35 Doseringen sker ved, at datamaten 3 først beordrer eksempelvis skruetransportøren 13 til at levere en passende 10 DK 172730 B1 portion, som vejecellen 31 afvejer, hvorefter skruetransportørerne 12, 13 og 14 enkeltvis og efter hinanden leverer passende portioner af kraftfoder og tilskudsblandinger, alt styret af datamaten 3 og afvejet af vejecellen 31, der ta-5 rerer mellem hver udvejning. Kraftfoder og tilskudsblandin gerne 5a, 6a, 7a og 8a udleveres ved hjælp af transportsneglene 12, 13, 14, 15, se fig. 1, over blandesneglen 17 og falder således ned i bunden af truget 29, se fig. 7.The dosage is done by the computer 3 first ordering, for example, the screw conveyor 13 to deliver an appropriate portion which the weighing cell 31 weighs, after which the screw conveyors 12, 13 and 14 individually and successively deliver appropriate portions of power feed and supplemental mixtures, all controlled of the computer 3 and weighed by the weighing cell 31, which acts between each weighing. Power feed and supplement mixes 5a, 6a, 7a and 8a are delivered by means of the transport augers 12, 13, 14, 15, see fig. 1, above the mixing auger 17, thus falling to the bottom of the trough 29, see FIG. 7th

10 Herefter doseres og afvejes grovfoderet 4a, der fortrinsvis lægger sig over skruevindingerne, se fig. 7 og 8.10 Then the coarse liner 4a is dosed and weighed, which preferably settles over the screw turns, see fig. 7 and 8.

I truget 29 i fig. 7 og 8 er der nu afvej et de nødvendige delportioner, alt styret af datamaten 3.In the trough 29 of FIG. 7 and 8 there are now weighed the necessary sub portions, all controlled by the computer 3.

Herefter skal delportionerne blandes og udfodres, hvilket er vist på fig. 9. Når motorerne, der driver sneglen 21, startes, f.eks. med en omdrejningsretning som vist på fig.Subsequently, the sub portions must be mixed and fed, as shown in FIG. 9. When the motors driving the auger 21 are started, e.g. with a direction of rotation as shown in FIG.

9, vil noget af grovfoderet 4a blive tvunget ned under 20 sneglen 21, og da dette giver øget friktion, sker der automatisk en løftning af sneglen 21 til position B eller til et område mellem position B og A, så der opstår et kanalområde 37 mellem sneglen 21 og truget 29.9, some of the coarse liner 4a will be forced down below the auger 21, and as this causes increased friction, the auger 21 will automatically be lifted to position B or to a region between positions B and A to form a channel region 37 between auger 21 and trough 29.

25 Når grovfoderet tvinges ned under blandesneglen 21 under samtidig løftning af denne fra position A til B, sker der en hurtig opblanding af de forskellige foderkomponenter 5a, 6a, 7a og 8a således, at der umiddelbart herefter, eventuelt samtidig med starten af sneglens 21 rotation, kan åb-30 nes for bundklappen 33 i den side, udfodringen skal ske.When the forage is forced down under the mixing auger 21 while simultaneously lifting it from position A to B, a rapid mixing of the various feed components 5a, 6a, 7a and 8a occurs, so that immediately thereafter, possibly simultaneously with the start of the auger 21 rotation. , can be opened for the bottom flap 33 in the side for feeding.

Sneglen 21 er ikke i fuldstændig indgreb med grovfoderet, men befinder sig oven på noget af foderet, og dette fremføres derfor ikke med sneglevindingernes fremføringshastighed, og en fuldstændig, eller i hvert fald en tilstrække-35 lig, opblanding sker umiddelbart før og til dels samtidig med udfodringen via bundklappen, når denne åbnes.The auger 21 is not fully engaged with the coarse fodder but is on top of some of the feed and this is therefore not conveyed at the feed rate of the auger and a complete, or at least adequate, mixing occurs immediately before and partly simultaneously. with the feeding via the bottom flap when opened.

Fig. 11-15 viser skitsemæssigt to yderligere udførelsesformer for ophængningen og funktionen af blandesneglen 21. Figurerne er skitsemæssige og viser således kun sneglen 21 og 5 dens ophængningsorganer, der omfatter ophængningsgavle 43, drivmotorerne 22 og en rektangulær ramme 44 over blandesneglen 21, idet sneglen hænger under rammen 44.FIG. 11-15 show schematically two further embodiments of the suspension and the function of the mixing auger 21. The figures are sketchy and thus show only the auger 21 and 5 its suspension means which include suspension end 43, the drive motors 22 and a rectangular frame 44 over the mixing auger 21, with the auger hanging below. frames 44.

Fig. 12 og 14 viser transportsneglen med ophængningsorganer 10 vist i fig. 11 og 13, men set fra den ene ende.FIG. 12 and 14 show the transport screw with suspension means 10 shown in FIG. 11 and 13, but seen from one end.

1 fig. 11 og 12 er blandesneglen 21 i hver ende ophængt i en drivmotor 22, der via gavlbeslag 43 eller lignende er ophængt i en rektangulær ramme 44. Rammen 44 er ophængt el-15 ler understøttet centralt på langsiderne under anvendelse af en arm 45 i hver side, hvilke armes nederste ende har et støttepunkt eller et leje 46 i indgreb med den ene ende af en vippearm 52 eller lignende i hver side. Vippearmenes 52 anden ende er koblet til undersiden af bunden af truget 29, 20 35 via et leje 47 i hver sin ende af en tværgående lejebøs ning 48, se fig. 12.1 FIG. 11 and 12, the mixing auger 21 is suspended at each end in a drive motor 22 which is suspended via a gable bracket 43 or the like in a rectangular frame 44. The frame 44 is suspended or supported centrally on the long sides using an arm 45 on each side. the lower end of said arms having a supporting point or bearing 46 engaging one end of a rocker arm 52 or the like on each side. The other end of the rocker arms 52 is coupled to the underside of the bottom of the trough 29, 20 via a bearing 47 at each end of a transverse bearing sleeve 48, see FIG. 12th

Man opnår hermed, at blandesneglen 21 og rammen 44 er "svømmende" ophængt og kan vippe som vist på fig. 15.It is hereby obtained that the mixing auger 21 and the frame 44 are "floating" suspended and can be tilted as shown in FIG. 15th

25 På fig. 13 og 14 vises en tredje udførelsesform for ophængningen af sneglen 21, Idet man, i stedet for vippearmene 52 med lejer m.v., udformer et aflangt eller et trekantformet hul 50 i hver af de nedadvendende arme 49 i rammen 44. På 30 blandetrugets 29 yderside er der fastgjort en styretap 51 i hver side, se fig. 14, for indgreb med hullerne 50 i hver sin arm 49. Herved fås en "svømmende" snegl 21, som frit kan indstille sig i forhold til mængden og konsistensen af de foderportioner, der skal blandes, og f.eks. også kan 35 indtage den stilling, der er vist på fig. 15.25 In FIG. 13 and 14, there is shown a third embodiment of the suspension of the auger 21, in which, instead of the rocker arms 52 with bearings, etc., an oblong or a triangular hole 50 is formed in each of the downwardly extending arms 49 in the frame 44. On the outside of the mixing trough 29 having a guide pin 51 attached to each side, see FIG. 14, for engagement with the holes 50 in each arm 49. Thereby, a "swimming" auger 21 is obtained which is freely adjustable in proportion to the amount and consistency of the feed portions to be mixed, and e.g. also, the position shown in FIG. 15th

For tydeligheds skyld er delportionerne af foder 4a, 5a, 6a, 7a, 8a kun vist på fig. 11 og på fig. 15 under udfod-ringen.For the sake of clarity, the partial portions of feed 4a, 5a, 6a, 7a, 8a are shown in FIG. 11 and in FIG. 15 during feeding.

5 Udførelsesformerne på fig. 11-15 er særligt velegnede til anvendelse i forbindelse med grovfoder, der er langsnittet og klumpet i strukturen, og det har i praksis vist sig at være en fordel, at sneglen kan bevæge sig opad, uden at dens akse nødvendigvis holdes parallel med trugets 29 bund.5 The embodiments of FIG. 11-15 are particularly suitable for use in coarse fodder which is longitudinally cut and lumped in the structure, and it has been found in practice to have an advantage that the auger can move upwards without necessarily keeping its axis parallel to the trough 29 bottom.

Blandingen af grovfoderportion 4a og foderkomponenterne 5a, 6a, 7a og 8a sker delvis ved, at disse dele bevæges langs trugets bund og sider med en lavere hastighed end sneglevindingens fremføringshastighed målt i snegleaksens længde- 15 retning. Grovfoderet 4a udkastes af sneglevindingerne på transportsneglen med en højere hastighed, end foderkomponenterne 5a, 6a, 7a og 8a fremføres, og man får herved en blanding, dels på den åbne bundklap 33 og dels, når foderet rammer foderbordet eller fodertruget, som vist på fig. 15.The mixing of coarse feed portion 4a and the feed components 5a, 6a, 7a and 8a occurs in part by moving these portions along the bottom and sides of the trough at a slower rate than the auger feed rate measured in the longitudinal direction of the auger axis. The coarse liner 4a is ejected by the auger windings on the conveyor auger at a higher rate than the feed components 5a, 6a, 7a and 8a are fed, thereby providing a mixture, partly on the open bottom flap 33 and partly when the feed hits the feed table or feed trough, as shown in FIG. . 15th
