Description
Oppløftningsanordning for traktortrukne redskaper. Lifting device for tractor-drawn implements.
Oppfinnelsen angår en oppløftningsan-ordning for traktortrukne redskaper, som kan løftes opp fra marken ved hjelp av traktorens hydrauliske løftestenger. The invention relates to a lifting device for tractor-drawn implements, which can be lifted from the ground using the tractor's hydraulic lifting rods.
Hensikten med anordningen er å redu-sere kraftforbruket ved løftning av redskaper, slik at tyngre redskaper kan løftes opp enn normalt. Videre er det hensikten å kunne regulere og begrense redskapets opp-løftning etter ønske og kunne oppnå at redskapet kan fires ned mot marken mere varsomt og langsomt enn normalt. Videre å gjøre det mulig å svinge redskapet i forhold til redskapet i nedsenket stilling og låse redskapet fast slik at det danner et hele med traktoren i oppløftet stilling. The purpose of the device is to reduce the power consumption when lifting implements, so that heavier implements can be lifted up than normal. Furthermore, the purpose is to be able to regulate and limit the lifting of the tool as desired and to be able to achieve that the tool can be lowered towards the ground more carefully and slowly than normal. Furthermore, to make it possible to swing the implement in relation to the implement in the lowered position and to lock the implement so that it forms a whole with the tractor in the raised position.
Oppfinnelsens anordning karakteriseres The device of the invention is characterized
ved en utvekslinganordning mellom traktorens trekkstenger og et toppstag som er forbundet med redskapet som gjør det mulig at toppstaget meddeles en redusert vinkelhastighet i forhold til normalt, slik at redskapet kan meddeles en i forhold til trekkstengenes svingning forhalet oppheising og nedfiring. by an exchange device between the tractor's drawbars and a top link which is connected to the tool which makes it possible for the top link to be given a reduced angular velocity compared to normal, so that the tool can be given a lifting and lowering which is delayed in relation to the drawbar's swing.
Et utførelseseksempel av anordningen er skjematisk vist på tegningen, som viser anordningen i forbindelse med en såma-skin for kunstgjødsel, bestående av en langstrakt kasse på hjul, festet til traktorens toppstag. Fig. 1 viser anordningen sett fra siden, mens fig. 2 viser den sett ovenfra. I fig. 1 er toppstillingene hos de forskjellige deler vist med punkterte linjer. An exemplary embodiment of the device is schematically shown in the drawing, which shows the device in connection with a sowing machine for artificial fertiliser, consisting of an elongated box on wheels, attached to the top strut of the tractor. Fig. 1 shows the device seen from the side, while Fig. 2 shows it seen from above. In fig. 1, the top positions of the various parts are shown with dotted lines.
Såmaskinen 1 er forbundet med traktorens toppstag 1, 8. Ytterendene av trekkstengene 4, 5 er forbundet med et med tap-per 6,7 forsynt stag 8 og på dette er oppbyg-get en stender, bestående av to skråstenger 9, 10, som løper sammen ved toppen og her er forbundet ved en bolt 11. I stenderen 9, 10 er ved toppen opplagret en trinse 12. Trekkstengene 4, 5 er i eksemplet festet til stenderfoten i punktene 6, 7. Toppstaget 2, 3 er festet til redskapets drag. The sowing machine 1 is connected to the tractor's top strut 1, 8. The outer ends of the tie rods 4, 5 are connected to a strut 8 provided with pins 6, 7 and on this is built a stand, consisting of two inclined rods 9, 10, which run together at the top and are here connected by a bolt 11. In the upright 9, 10, a pulley 12 is stored at the top. drag.
I eksemplet er det mellom trekkstengene 4, 5 og toppstaget en leddstangforbin-delse 13, 14, som danner en slags kneledd-forbindelse. Stengene 14, 14 er festet til staget 8 og stengene 13, 13 (som nærmest traktoren grener ut i to grener) er svingbart festet til toppstagene 2, 3. En wire eller kjetting 15 som er lagt om trinsen 12 er ved flere grener festet til redskapskasse 1 og er i den annen ende festet til et sted på stangen 13. In the example, there is a connecting rod connection 13, 14 between the tie rods 4, 5 and the top strut, which forms a kind of knee joint connection. The rods 14, 14 are attached to the rod 8 and the rods 13, 13 (which branch out into two branches closest to the tractor) are pivotably attached to the top rods 2, 3. A wire or chain 15 which is placed around the pulley 12 is attached at several branches to tool box 1 and is attached at the other end to a place on the rod 13.
Når nå traktorens trekkstenger 4, 5 hydraulisk svinges oppad, vil stenderen 9, 10 løftes tilsvarende. Vinkelen mellom toppstaget og stenderen vil minke og stengene 14 vil skyve i stangen 13, slik at wirens feste 16 vil løftes mye mere enn enden av trekkstengene 4, 5, slik at wiren 15 herved slak-kes under redskapets oppløftning i forhold til trekkstengenes svingning, og redskapets oppløftning vil derved forhales. På grunn av redskapets forhalte og langsommere oppløftning vil kraftforbruket reduseres tilsvarende, slik at man med samme hydrauliske kraft kan løfte langt tyngre redskap enn normalt. Redskapets effektive løftning vil også bli redusert, hvilket også er en for-del. Ved den påfølgende nedfiring av redskapet mot marken vil toppstaget tilsvarende få en mindre vinkelhastighet enn trekkstengene, idet wiren 15 holder igjen, slik at redskapet fires langsommere og mere varsomt mot marken, og ikke så lett utset-tes for støt. Festepunktet 16 på stangen 13 kan flyttes, hvorved nevnte forhaling kan reguleres i størrelse og en har her en regu-leringsmulighet for oppheisningshastighe-ten og firingshastigheten, samt løftehøy-den. When now the tractor's drawbars 4, 5 are hydraulically swung upwards, the uprights 9, 10 will be lifted accordingly. The angle between the top stay and the upright will decrease and the rods 14 will push into the rod 13, so that the wire attachment 16 will be lifted much more than the end of the drawbars 4, 5, so that the wire 15 is thereby slackened during the raising of the tool in relation to the swing of the drawbars, and the tool's lifting will thereby be delayed. Due to the tool's retarded and slower lifting, the power consumption will be reduced accordingly, so that with the same hydraulic power you can lift much heavier tools than normal. The tool's effective lift will also be reduced, which is also an advantage. During the subsequent lowering of the implement towards the ground, the top strut will correspondingly have a smaller angular velocity than the drawbars, as the wire 15 holds back, so that the implement is lowered more slowly and more carefully towards the ground, and is not so easily exposed to shocks. The attachment point 16 on the rod 13 can be moved, whereby said hauling can be adjusted in size and here you have an adjustment option for the hoisting speed and the lowering speed, as well as the lifting height.
I stedet for en enkel wire 15, som vist kan wireenden føres om en taljetrinse, som så festes til stangen 13. Redskapets opp-heisnings- og nedfiringsforhaling kan ved slik talj eanordning økes ytterligere. Forhalingen øker nemlig jo lenger ut på stangen 13 wiren eller taljen festes, og ved flytning av festepunktet 16 oppnår man en regule-ring av forhalingen. Instead of a simple wire 15, as shown, the end of the wire can be passed around a hoist pulley, which is then attached to the rod 13. The hoisting and lowering speed of the tool can be further increased by such a hoist arrangement. The drag increases the further out on the rod 13 the wire or the hoist is attached, and by moving the attachment point 16 a regulation of the drag is achieved.
Når redskapets oppheisning og delenes oppsvingning er nådd maksimum (se punk-tert stilling fig. 1) vil staget 8 legge seg opp under toppstaget 2, 3 og stenderen 9, 10 kan da også legge seg mot en ikke vist stopper. Redskapet vil dermed fastlåses til traktoren og danne et hele med denne. Når redskapet er nedfirt mot marken vil traktoren kunne svinge i forhold til redskapet, som vil følge etter som et sleperedskap. When the lifting of the implement and the upswing of the parts have reached the maximum (see dotted position fig. 1) the rod 8 will lie up under the top rod 2, 3 and the strut 9, 10 can then also lie against a stop not shown. The tool will thus be locked to the tractor and form a whole with it. When the implement is brought down to the ground, the tractor will be able to turn in relation to the implement, which will follow as a towing device.
Utvekslingsanordningen og wireførin-gen kan naturligvis endres på forskjellig vis. Således kan wireenden også festes til en svingbar stang, som er svingbart forbundet med toppstagene 2, 3. The exchange device and the wire guide can of course be changed in different ways. Thus, the wire end can also be attached to a pivotable rod, which is pivotably connected to the top struts 2, 3.
