Kendte vogne af denne type er indrettet på en sådan måde, at de øvrige effektkrævende funktioner i vognen, såsom foderpumpe, foderomrører, halmdoseringsapparat, etc drives hydraulisk ved hjælp af en hydraulisk pumpe, der drives af en benzin, diesel eller gasdreven hjælpemotor indbygget i vognen. Opfindelsen er ejendommelig ved, at den batteridrevne foder- eller halmstrøvogn, foruden det faste sæt traktionsbatterier, er udstyret med et udskifteligt højkapacitetsbatteri (lO) af genopladelig type, og at vognens forskellige mekaniske funktioner drives elektrisk ved hjælp af en eller flere elektromotorer, som enten er koblet direkte til de respektive mekaniske arbejdsfunktioner i vognen, eller som fungerer indirekte via et hydraulisk system, hvis pumpe drives af en elektromotor. Formålstjenligt er det hydrauliske system indrettet med en eller flere magnetventiler beregnet dels til energioptimering af systemet, dels til sikring af præcis foderdosering og/eller halmdosering. Detudskiftelige højkapacitetsbatteri (l O) kan ifølge opfmdelsen med fordel være et batteri af typen lithium-ion, nikkel-cadmium, eller en tilsvarende genopladelig batteritype med høj kapacitet i forhold til størrelse og vægt.

The power pack can then be easily accessible, preferably externally on the trolley, for example on the front or rear of the trolley for quick and effortless replacement of the battery.
Description
Den foreliggende opfindelse angår en batteridreven foder- eller halmstrøvogn, især til brug på pelsdyrfarme, og nærmere bestemt af den i indledningen til krav 1 anførte art.The present invention relates to a battery-powered feed or straw trolley, in particular for use on fur farms, and more particularly to the kind set forth in the preamble of claim 1.
Kendte vogne af den omhandlede type er sædvanligvis udstyret med et sæt faste, genopladelige batterier beregnet til elektrisk traktion af vognen. De øvrige effektkrævende funktioner i vognen, såsom foderpumpe, foderomrører, halmdoseringsapparat, etc, drives sædvanligvis hydraulisk ved hjælp af en hydraulisk pumpe, der er koblet til en dieselmotor indbygget i vognen.Known carriages of the type in question are usually equipped with a set of solid, rechargeable batteries intended for electric traction of the carriage. The other power-intensive functions of the carriage, such as feed pump, feed stirrer, straw dosing apparatus, etc., are usually operated hydraulically by means of a hydraulic pump coupled to a diesel engine built into the carriage.
Fra beskrivelsen til WO 2014/120000 A1 kendes en fremgangsmåde til fodring i kvægstalde og et maskinsæt til brug ved denne fremgangsmåde. Fodringen foregår under anvendelse af en traktor og en til denne koblet fodermixer, som kan trækkes rundt i stalden af traktoren. Traktoren er udstyret med en hydraulisk læssegrab, og benyttes på sædvanlig måde til påfyldning af foder i fodermixerens åbne foderkar. Under denne proces er traktoren frakoblet fodermixeren. Fodermixeren er forsynet med to hydraulisk aktiverbare støtteben, som tillader fodermixeren at stå alene, når traktoren er frakoblet. Endvidere er fodermixeren forsynet med to elektrisk drevne blandesnegle, som er indbygget i karret. Ved hjælp af disse snegle blandes de forskellige foderemner, der fyldes i karret.From the description to WO 2014/120000 A1, a method for feeding in cattle sheds and a machine set for use in this method is known. Feeding takes place using a tractor and a feed mixer coupled to it, which can be dragged around the stable by the tractor. The tractor is equipped with a hydraulic loading grab and is used in the usual way for loading feed into the open mixer of the feed mixer. During this process, the tractor is disconnected from the feed mixer. The feed mixer is equipped with two hydraulically activatable support legs, which allow the feed mixer to stand alone when the tractor is disconnected. Furthermore, the feed mixer is provided with two electrically driven mixing augers, which are built into the tub. Using these augers, mix the various feed items that are loaded into the tub.
Når foderpåfyldningen er afsluttet og foderet blandet kobles traktoren til fodermixeren igen, og denne køres på sædvanlig måde rundt i stalden på de fodergange, der er indrettet i stalden. Dette sker under samtidig aflæsning af foderet på foderborde, der befinder sig langs siderne af fodergangen. Til brug for aflæsningen er fodermixeren forsynet med en hydraulisk aktiveret sidelåge i hver side, og ved at åbne en låge og samtidig aktivere blandesneglene drives foderblandingen ud af fodermixerens kar i den pågældende side. Dette sker under kørslen og i kontrolleret rate, således at foderet bliver fordelt jævnt og i passende mængde på foderbordene.When the feed is completed and the feed mixed, the tractor is coupled to the feed mixer and this is usually driven around the barn on the feed corridors arranged in the barn. This is done while simultaneously loading the feed on feed tables located along the sides of the feed aisle. For the purpose of reading, the feed mixer is provided with a hydraulically actuated side door on each side, and by opening a door and simultaneously activating the mixing augers, the feed mix is driven out of the feed mixer vessel on that side. This is done during the run and at a controlled rate, so that the feed is distributed evenly and in appropriate quantity on the feed tables.
De forskellige fodermixerfunktioner (blandesnegle, sidelåger og støtteben) drives primært v hj af elektrisk kraft, enten direkte med elektromotorer, eller indirekte via en elektrisk dreven hydraulisk pumpe. Effekten til disse funktioner leveres af batterier indbygget i fodermixeren, og er altså ikke afhængig af kraftoverførsel fra traktoren. Batterierne er af genopladelig type, og oplades periodevis fra en stationær energikilde. Batterierne er arrangeret i fire serieforbundne powerpacks, som hver for sig er anbragt i en kasseformet, udskiftelig indkapsling. Traktoren selv drives v hj af en mindre forbrændingsmotor, som typisk er en dieselmotor. Genopladningen af batterierne foregår i de perioder, hvor fodermixeren ikke er i brug, eksempelvis om natten.The various feed mixer functions (mixing augers, side doors and support legs) are driven primarily by electric power, either directly with electric motors, or indirectly via an electrically driven hydraulic pump. The power for these functions is provided by batteries built into the feed mixer, and thus does not depend on power transmission from the tractor. The batteries are rechargeable and are periodically charged from a stationary source of energy. The batteries are arranged in four series-connected power packs, each of which is arranged in a box-shaped, interchangeable enclosure. The tractor itself is powered by a smaller internal combustion engine, which is typically a diesel engine. Recharging the batteries takes place during periods when the feed mixer is not in use, for example at night.
Fremgangsmåden jf WO 2014/120000 A1 til fodring i kvægstalde og det tilhørende maskinsæt er ikke anvendelig til fodring i minkstalde, hvor fodringen foregår på en ganske anden måde. Burene i en minkfarm er trådbure, der er opstillet ved siden af hinanden i lange lige rækker langs fodergange. Fodergangene er indrettet til kørsel med motordrevne fodervogne, som under fodringen køre ned langs rækkerne af bure. Under passagen af burene afsættes en afmålt foderdosis ovenpå hvert enkelt bur. Foderet er en pastaagtig blanding af eksempelvis fiske- og slagteriaffald. Foderet doseres individuelt til hvert enkelt bur, således at der tages hensyn til minkens udviklingstrin og antallet af dyr i hvert bur.The procedure cf. WO 2014/120000 A1 for feeding in cattle stables and the associated machine set is not applicable for feeding in mink stables, where feeding takes place in a completely different way. The cages in a mink farm are wire cages arranged side by side in long straight rows along the feed aisles. The feed aisles are designed for driving with powered feed trucks, which during feeding feed down the rows of cages. During the passage of the cages, a metered feed dose is deposited on top of each cage. The feed is a paste-like mixture of, for example, fish and slaughterhouse waste. The feed is dosed individually for each cage, taking into account the developmental stages of the mink and the number of animals in each cage.
Moderne minkfarme har ofte op til flere tusinde bure, og der skal fodres hver dag, hvorfor fodringen nødvendigvis må foregå på den mest rationelle og tidseffektive måde. Udfodringen foregår ’’flyvende”, dvs medens fodervognen er i konstant bevægelse ned langs rækken af bure. Der er ganske enkelt ikke tid til at standse op ved hvert enkelt bur, når der afgives en foderklat. Et minkbur har sædvanligvis en bredde på 30 cm, og under fodringen køres der med en hastighed på mellem 3 og 6 km i timen. Forudsættes det, at fodervognen bevæger sig med en kørehastighed på 6 km i timen bliver der et tidsinterval af størrelsesordenen 0,15 til 0,2 sec til fodring ved hvert enkelt bur. Inden for dette korte tidsinterval skal foderet både udpumpes i nøjagtig afmålt mængde og afsættes oven på buret som en klat. Af hensyn til økonomien i minkavlen og dyrenes trivsel er kravene til gentagelsesnøjagtigheden i doseringen extrem høj.Modern mink farms often have up to several thousand cages, and every day they must be fed, which is why feeding must necessarily take place in the most rational and time-efficient way. The feeding takes place '' flying '', that is, while the feed cart is constantly moving down the row of cages. There is simply no time to stop at each cage when feeding a feed. A mink cage usually has a width of 30 cm, and during feeding is run at a speed of between 3 and 6 km per hour. Assuming that the feed truck moves at a speed of 6 km per hour, there will be a time interval of the order of 0.15 to 0.2 sec for feeding at each cage. Within this short time interval, the feed must be both pumped out in precisely measured quantity and deposited on top of the cage as a clot. Due to the economy of the mink breed and the well-being of the animals, the requirements for repeat accuracy in the dosage are extremely high.
Minkfarmene bygges i dag ofte som stålhaller med lukkede sider. Stålhaller af denne type er følgelig dårligere ventilerede end de tidligere benyttede åbne minkfarme, hvor staldlængernes sider er helt åbne. De lukkede stålhaller giver anledning til et alvorligt luftforureningsproblem, når der, som det er almindeligt i dag, benyttes dieselmotordrevne foder- eller halmstrøvogne, hvis emission af skadelige udstødsgasser forurener luften i stalden.Today, the mink farms are often built as steel halls with closed sides. Steel halls of this type are consequently less ventilated than the previously used open mink farms, where the sides of the barn lengths are fully open. The closed steel halls give rise to a serious air pollution problem when, as is common today, diesel-powered feed or straw trolleys are used, the emission of harmful exhaust gases polluting the air in the stable.
Et andet problem i forbindelse med anvendelsen af diesel- og benzinmotorer i lukkede staldrum, især på minkfarme, er det håraffald, som dyrene ved deres naturlige hårtab afgiver til omgivelserne. Håraffaldet består af ultrafine hår, som har en uheldig tilbøjelighed til at sætte sig i motorernes luft- og brændstoffiltre med tilstopning af disse til følge. Resultatet er, at motorerne oftere end normalt skal serviceres, dvs have filtrene renset eller udskiftet.Another problem associated with the use of diesel and gasoline engines in enclosed stables, especially on mink farms, is the hair loss that the animals emit to their surroundings by their natural hair loss. The hair loss consists of ultra-fine hairs, which have an unfortunate tendency to get caught in the air and fuel filters of the engines, causing them to become clogged. The result is that the motors must be serviced more often than usual, ie have the filters cleaned or replaced.
Med det formål, at komme de ovennævnte problemer til livs, foreslås det ifølge opfindelsen, at gøre de pågældende foder- eller halmstrøvogne fuldt elektrificerede, dvs således, at ikke kun traktionen, men også de forskellige arbejdsfunktioner i vognene drives med elektrisk kraft. På den måde undgår man luftforureningen i staldene og problemerne med den jævnlige tilstopning af forbrændingsmotorernes filtre. Opgavens løsning består ifølge opfindelsen i, at indrette foder- eller halmstrøvognene således som angivet i den kendetegnende del af krav 1.In order to overcome the aforementioned problems, it is proposed according to the invention to fully electrify the feed or straw trolleys concerned, that is, not only the traction but also the various working functions of the trolleys are driven by electric power. This avoids the air pollution in the stables and the problems with the regular clogging of the combustion engine filters. According to the invention, the solution of the task consists in arranging the feed or straw trolleys as stated in the characterizing part of claim 1.
Opfindelsen er ejendommelig ved, at den batteridrevne foder- eller halmstrøvogn er forsynet med en foderpumpe, som er indrettet med et el-hydraulisk drivsystem, hvis væsentligste bestanddele er en hydraulikpumpe, der drives af en elektromotor, der forsynes med strøm fra højkapacitetsbatteriet. Endvidere ved at omfatte en eller flere hydrauliske magnetventiler af en type med kort responstid, en hydraulikmotor, der driver fodervognens foderpumpe, og en bypass-forbindelse indsat mellem hydraulikpumpen og en til hydrauliksystemet hørende olietank for direkte trykaflastning af hydraulikpumpen i de tidsintervaller, hvor foderpumpens hydraulikmotor er deaktiveret, dvs i de tidsintervaller, hvor der ikke pumpes foder ud.The invention is characterized in that the battery-powered feed or straw trolley is provided with a feed pump which is equipped with an electric-hydraulic drive system, the main components of which are a hydraulic pump powered by an electric motor powered by the high-capacity battery. Further, by including one or more hydraulic solenoid valves of a type with a short response time, a hydraulic motor operating the feed pump of the feed truck, and a bypass connection inserted between the hydraulic pump and an oil tank belonging to the hydraulic system for direct pressure relief of the hydraulic pump during the time intervals where the feed pump hydraulic motor is deactivated, ie during the time intervals where no feed is pumped out.
Hydraulikpumpen arbejder kontinuert så længe vognen er i drift. Ved aktivering og deaktivering af magnetventilerne er det muligt, at styre olieflowet til foderpumpemotoren på en sådan måde, at foderet udpumpes i nøje afmålte doser. Udpumpningen foregår i korte tidsintervaller medens fodervognen passerer minkburene. Foderslangen er til stadighed åben under fodringsprocessen; det er alene foderpumpen - som er en deplacementspumpe - der bestemmer mængden af foder, som afgives i hvert pumpeinterval. Magnetventilernes korte reaktionstid giver udpumpningssystemet en ekstrem hurtig respons, hvilket er en betingelse for, at man kan opnå den tilstræbte høje præcision i foderdoseringen. En nøjagtig fodertildeling til de enkelte bure er af afgørende betydning for økonomien i minkavlen og for dyrenes trivsel.The hydraulic pump operates continuously as long as the trolley is in operation. By activating and deactivating the solenoid valves, it is possible to control the oil flow to the feed pump motor in such a way that the feed is pumped out in carefully metered doses. The pumping takes place at short intervals as the feed carriage passes the mink cages. The feed hose is constantly open during the feeding process; only the feed pump - which is a displacement pump - determines the amount of feed delivered in each pump interval. The short reaction time of the solenoid valves gives the pumping system an extremely fast response, which is a condition for achieving the desired high precision in the feed dosage. An accurate feed allocation to the individual cages is crucial for the economy of the mink breed and for the well-being of the animals.
I de mellemintervaller, hvor der ikke pumpes foder ud, sikrer hydrauliksystemets magnetventiler og bypass-forbindelsen, at der sker omløb til tank. Man undgår på den måde, at hydraulikpumpen bruger unødig effekt til tomgangskørsel under modtryk. Princippet i hydrauliksystemet medvirker på denne måde til, at den til rådighed værende el-kapacitet i power-packen bruges mest effektivt, dvs at driftstiden for en power-pack bliver så lang som mulig.In the intermediate intervals where no feed is pumped out, the hydraulic system's solenoid valves and the bypass connection ensure that the tank is circulated. This prevents the hydraulic pump from using unnecessary power for idling under pressure. In this way, the principle of the hydraulic system helps to use the available electrical capacity in the power pack most efficiently, ie the operating time of a power pack is as long as possible.
Det bemærkes, at den største effektforbruger i fodervognen er foderpumpen, hvorfor den beskrevne metode til at økonomisere med batterikapaciteten er af afgørende betydning for den el-drevne fodervogns anvendelighed i praksis. Det el-hydrauliske drivsystem for foderpumpen er med andre ord en forudsætning for, at fodervognen kan indrettes fuldt elektrificeret, og dermed, at den tilsigtede forbedring af luftkvaliteten i staldbygningerne opnås. Den fulde elektrificering af fodervognen har samtidig den fordel, at støjniveauet sænkes, og at man undgår den for operatøren uønskede varmeafgivelse fra en benzineller dieselmotor. Begge forhold bidrager i høj grad til at forbedre arbejdsmiljøet i forbindelse med fodringsarbejdet. Det er også en fordel, at servicebehovet i forbindelse med den beskrevne tilstopning af dieselmotorens forskellige filtre minimeres.It is noted that the main power consumer in the feed cart is the feed pump, which is why the described method of economizing with the battery capacity is of crucial importance for the utility of the electric powered feed cart in practice. In other words, the electric-hydraulic drive system for the feed pump is a prerequisite for the feed trolley to be fully electrified, and thus to achieve the intended improvement of the air quality in the stable buildings. At the same time, the full electrification of the feed trolley has the advantage of lowering the noise level and avoiding the undesirable heat output of the operator from a gasoline or diesel engine. Both conditions greatly contribute to improving the working environment in connection with feeding work. It is also an advantage that the service requirements associated with the described clogging of the various filters of the diesel engine are minimized.
I en foretrukken udførelsesform er det udskiftelige højkapacitetsbatteri indkapslet som en separat enhed, som udgør en kompakt power-pack, og denne power-pack er formålstjenligt monteret lettilgængelig, fortrinsvis udvendig på vognen, eksempelvis på forenden eller bagenden af vognen. Ved at indkapsle højkapacitetsbatteriet på denne måde opnår man en praktisk og let håndterbar batterienhed, som er hurtig at skifte. Specielt når enheden samtidig, som anført, er placeret lettilgængelig udvendig på vognen.In a preferred embodiment, the replaceable high capacity battery is encapsulated as a separate unit constituting a compact power pack, and this power pack is conveniently mounted readily accessible, preferably externally of the carriage, for example at the front or rear of the carriage. By encapsulating the high-capacity battery in this way, you obtain a convenient and easily manageable battery unit, which is quick to change. Especially when at the same time, as stated, the unit is easily accessible on the outside of the carriage.
I en særlig udførelsesform er vognen udstyret med en elektrisk koblingsanordning, som gør det muligt at foretage en tilkobling af power-packen til det elektriske traktionssystem. Power-packen opnår på denne måde en supplerende funktion som backup for traktionsbatteriet i tilfælde, hvor dette er afladet eller næsten afladet for strøm. Fodrings- eller strøarbejdet kan i sådanne mere ekstreme situationer gennemføres uden unødig ophold for genopladning af traktionsbatterierne.In a particular embodiment, the trolley is equipped with an electrical coupling device which makes it possible to connect the power pack to the electric traction system. In this way, the power pack achieves an additional function as backup for the traction battery in cases where this is discharged or almost discharged for power. In such more extreme situations, the feeding or littering can be carried out without unnecessary delay for recharging the traction batteries.
Til meget krævende opgaver, eksempelvis når der er tale om fodring eller strøarbejde på meget store mink- eller pelsdyrfarme, kan det ifølge opfindelsen være en fordel, at udstyre foder- eller halmstrøvognen med en trailer, der er koblet efter vognen. På traileren kan der medbringes op til flere power-packs, og via et fleksibelt el-kabel kobles disse til vognens elektriske drivsystem. På denne måde kan vognen opnå en nærmest ubegrænset rækkevidde både hvad kørestrækning og arbejdskapacitet angår.For very demanding tasks, for example in the case of feeding or bedding on very large mink or fur farms, it may be advantageous according to the invention to equip the feed or straw stroller with a trailer coupled to the trolley. The trailer can carry up to several power packs, and via a flexible electric cable these are connected to the car's electric drive system. In this way, the trolley can achieve an almost unlimited range both in terms of driving distance and working capacity.
En noget tilsvarende egenskab kan en foder- eller halmstrøvogn af den i krav 7 anførte hybridtype opnå. Vognens hybride drivsystem omfatter, foruden de faste, genopladelige traktionsbatterier og den udskiftelige power-pack, en relativ lille forbrændingsmotor, der driver en elektrisk generator. Motoren kan være en benzin-, diesel- eller gasmotor. Ved hjælp af den motordrevne generator kan vognens power-pack og/eller genopladelige traktionsbatterier på i og for sig kendt vis oplades, samtidig med at vognen er i drift. Resultatet er, at vognens rækkevidde både hvad kørestrækning og arbejdskapacitet angår, er ubegrænset.A somewhat similar property can be obtained from a feed or straw trolley of the hybrid type of claim 7. The car's hybrid drive system includes, in addition to the fixed, rechargeable traction batteries and the interchangeable power pack, a relatively small internal combustion engine that drives an electric generator. The engine can be a gasoline, diesel or gas engine. By means of the motor-driven generator, the car's power-pack and / or rechargeable traction batteries can be recharged in a manner known per se, while the carriage is in operation. The result is that the range of the wagon in terms of both driving distance and working capacity is unlimited.
Opfindelsen skal forklares nærmere i det følgende i forbindelse med tegningen, hvor Fig. 1 viser en elektrificeret fodervogn i en første udførelsesform ifølge opfindelsen, vist skematisk i sidebillede,BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail below with reference to the drawing, in which 1 shows an electrified feed trolley in a first embodiment according to the invention, shown schematically in side view,

Fig. 6 viser en elektrificeret fodervogn i en anden udførelsesform, hvor et antal powerpacks medbringes i en trailer, der er koblet til fodervognen, vist i sidebillede.FIG. 6 shows an electrified feed truck in another embodiment, where a number of power packs are carried in a trailer coupled to the feed truck, shown in side view.
I den på tegningens fig. 1 og 2 viste udførelsesform består fodervognen i det væsentlige af et chassis 1, et sæt forhjul 2 og et sæt baghjul 3, en foderbeholder 4, en førerplads 5 med sæde 6 og rat 7, en fleksibel foderdoseringsslange 8, og en frontmonteret bæreramme 9 for en power-pack 10. Fodervognen er knækstyret, idet chassiset er todelt med en forende 1a og en bagende 1b. De to chassisdele er forbundet i et fælles drejeled 11, der befinder sig omtrent midt i chassiset. Foderbeholderen 4 er monteret på den bagerste chassisdel 1b, og førerpladsens sæde 6 er anbragt på den forreste chassisdel 1a. En skråtstillet stander 12 anbragt umiddelbart foran sædet 6 tjener som instrumentbrædt og som støtte for rattet 7.In the FIG. 1 and 2, the feed carriage consists essentially of a chassis 1, a set of front wheels 2 and a set of rear wheels 3, a feed container 4, a driver seat 5 with seat 6 and steering wheel 7, a flexible feed dosing hose 8, and a front mounted support frame 9 for a power pack 10. The feed carriage is crank-driven, the chassis being divided in two with a front end 1a and a rear end 1b. The two chassis parts are connected in a common pivot joint 11 located approximately in the middle of the chassis. The feeding container 4 is mounted on the rear chassis part 1b and the seat 6 of the driver's seat is arranged on the front chassis part 1a. An oblique stand 12 located immediately in front of the seat 6 serves as dashboard and as a support for the steering wheel 7.
Chassiset 1 er fremstillet af plade, der er svejset op i kasseform. Indvendig i chassiset fremkommer på denne måde et forreste og bagerste hulrum, hvori fodervognens foderpumpe, hydrauliksystem, hydraulikpumpe med tilhørende elektromotor, traktionsbatteri og øvrige tekniske komponenter er anbragt. De pågældende komponenter er ikke vist på tegningen.The chassis 1 is made of plate welded in box form. In this way, a front and rear cavity is formed inside the chassis in which the feed pump's feed pump, hydraulic system, hydraulic pump with associated electric motor, traction battery and other technical components are arranged. The components in question are not shown in the drawing.
Forrest på chassiset 1 er bærerammen 9 for power-packen 10 monteret. Bærerammen 9 udgøres af en rektangulær profiljernsramme 13, som forneden er forsynet med et bundstykke 14 i hver side, og hvor der på rammens to sidestykker 15 i hver side af rammen er anbragt en svingbar gribelaske 16. De to gribelasker kan åbnes ud til siderne (ikke vist), hvorved power-packen 10 kan indsættes eller udtages fra bærerammen 9. I lukket tilstand (som vist på tegningen) griber laskerne ind omkring power-packen, hvorved denne fastholdes. Gribelaskerne 16 er forsynet med ikke viste låsemekanismer, der sikrer laskernes lukkede stilling.At the front of the chassis 1, the support frame 9 for the power pack 10 is mounted. The support frame 9 consists of a rectangular profile iron frame 13, which is provided at the bottom with a base piece 14 on each side, and on which the two side pieces 15 are arranged on each side of the frame a pivotable gripper shaft 16. The two gripper shelves can be opened out to the sides ( not shown), whereby the power pack 10 can be inserted or removed from the carrier frame 9. In the closed state (as shown in the drawing), the lasers engage around the power pack, thereby holding it. The gripping latches 16 are provided with locking mechanisms (not shown) which ensure the closed position of the latches.
En power-pack 10 af den her omhandlede type er sædvanligvis sammensat af et antal enkeltbatterier for at opnå den fornødne elektriske spænding og kapacitet. Enkeltbatterierne er indkapslet i et lukket hus 17 af metalplade. Huset 17 er i dette tilfælde formet som en flad kasse, der passer ind i bærerammen 9. Øverst på huset 17 er anbragt en tilkoblingsanordning 18, hvor den elektriske tilslutning til selve fodervognen finder sted ved hjælp af et ikke vist kabel.A power pack 10 of the type in question is usually composed of a number of single batteries to obtain the required electrical voltage and capacity. The single batteries are enclosed in a closed metal plate housing 17. In this case, the housing 17 is shaped as a flat box that fits into the support frame 9. At the top of the housing 17 is a connecting device 18, where the electrical connection to the feed carriage itself takes place by means of a cable not shown.
Fodervognens traktionssystem omfatter en hjulmotor, der er monteret indvendig i den bagerste chassisdel 1b. Hjulmotoren forsynes med elektricitet fra et sæt fast monterede blysyrebatterier, der er anbragt i den forreste eller bagerste chassisdel 1a eller 1b. Batterierne giver vognen en samlet køretid på 8 - 10 timer, hvilket i de fleste tilfælde er fuldt tilstrækkeligt til den opgave, vognen skal klare.The feed traction system comprises a wheel motor mounted inside the rear chassis part 1b. The wheel motor is supplied with electricity from a set of fixed lead-acid batteries located in the front or rear chassis part 1a or 1b. The batteries give the trolley a total driving time of 8 - 10 hours, which in most cases is fully sufficient for the task the trolley is to handle.
Vognen er forsynet med et hydrauliksystem, hvis hydraulikpumpe drives af en elektromotor, der forsynes med strøm fra power-packen. Hydraulikpumpen arbejder kontinuert så længe vognen er i drift. I hydrauliksystemet indgår en hydraulisk motor, der driver vognens foderpumpe. Endvidere omfatter hydrauliksystemet en eller flere magnetventiler, hvormed den hydrauliske foderpumpemotor kan aktiveres og deaktiveres. Magnetventilerne gør det muligt, at styre foderpumpemotoren på en sådan måde, at foderet udpumpes i nøje afmålte doser. Udpumpningen foregår i korte intervaller under fodervognens passage af de i minkfarmen rækkevis opstillede minkbure. Foderslangen 8 er til stadighed åben under fodringsprocessen; det er alene foderpumpen, som bestemmer mængden af foder, som afgives i hvert pumpeinterval via foderslangen.The trolley is equipped with a hydraulic system, the hydraulic pump of which is powered by an electric motor, which is powered by the power pack. The hydraulic pump operates continuously as long as the trolley is in operation. The hydraulic system includes a hydraulic motor that drives the car's feed pump. Furthermore, the hydraulic system comprises one or more solenoid valves, by means of which the hydraulic feed pump motor can be activated and deactivated. The solenoid valves make it possible to control the feed pump motor in such a way that the feed is pumped out in carefully metered doses. The pumping takes place at short intervals during the passage of the feed carriage of the mink cages arranged in series in the mink farm. The feed hose 8 is constantly open during the feeding process; it is only the feed pump that determines the amount of feed delivered in each pump interval via the feed hose.
Magnetventilernes korte reaktionstid giver udpumpningssystemet en ekstrem hurtig respons, hvilket er en betingelse for, at man kan opnå den tilstræbte præcision i foderdoseringen. En nøjagtig fodertildeling til de enkelte bure er af afgørende betydning for økonomien i minkavlen og for dyrenes trivsel. I de mellemintervaller, hvor der ikke pumpes foder ud, sikrer hydrauliksystemets magnetventiler sammen med en bypassforbindelse, at der sker omløb fra hydraulikpumpe til tank. Man undgår på denne måde, at hydraulikpumpen bruger effekt til unødig tomgangskørsel under modtryk. Princippet i hydrauliksystemet medvirker til, at de til rådighed værende amperetimer i power-packen 10 bruges mest effektivt, således at driftstiden for hver power-pack bliver så lang som mulig.The short reaction time of the solenoid valves gives the pumping system an extremely fast response, which is a condition for achieving the desired precision in the feed dosage. An accurate feed allocation to the individual cages is crucial for the economy of the mink breed and for the well-being of the animals. In the intermediate intervals where no feed is pumped out, the hydraulic system's solenoid valves, together with a bypass connection, ensure that the hydraulic pump to the tank is circulated. In this way, it is avoided that the hydraulic pump uses power for unnecessary idling under back pressure. The principle of the hydraulic system helps to use the available amperage hours in the power pack 10 most efficiently, so that the operating time of each power pack is as long as possible.
Det i fig. 5 viste hjælperedskab 20 benyttes, når power-packen 10 skal udskiftes. Redskabet består i hovedsagen af et profiljernsstel 21, som har en vandret basisramme 22, og en på denne monteret lodret søjle 23. På søjlen er en gaffeldel 24 lejret lodret forskydeligt. Gaffeldelen 24 kan bevæges op og ned ved hjælp af et greb 25, som betjenes manuelt. Ved brug køres redskabet med gaffeldelen 24 ind under power-packen 10, som herefter løftes fri af bærerammen 9 ved hjælp af grebet 25. Power-packen kan nu køres frem til ladestationen og anbringes i denne.The FIG. 5, the auxiliary tool 20 shown when the power pack 10 is to be replaced. The tool consists mainly of a profile iron frame 21, which has a horizontal base frame 22, and a vertical column 23 mounted thereon. On the column a fork part 24 is mounted vertically displaceable. The fork part 24 can be moved up and down by means of a handle 25 which is operated manually. In use, the implement with the fork part 24 is driven under the power pack 10, which is then lifted free of the support frame 9 by the handle 25. The power pack can now be driven to the charging station and placed therein.
I fig. 6 er den elektrificerede fodervogn vist i en anden udførelsesform, hvor et antal powerpack-batterier 10 medbringes på en trailer 30, som er efterspændt fodervognen. Tegningen er umiddelbart forståelig, og skal derfor ikke forklares nærmere her.In FIG. 6, the electrified feed trolley is shown in another embodiment where a plurality of powerpack batteries 10 are carried on a trailer 30 which is post-tensioned the feed trolley. The drawing is immediately understandable and should therefore not be explained in more detail here.
