Description
Traktor med hydraulisk hev- og senkbar lastearm. Tractor with hydraulic lifting and lowering loading arm.
Foreliggende oppfinnelse angår traktorer med en foran montert, hydraulisk hev- og senkbar lastearm, som etter at den er nedsenket slik at redskapet som er anbragt på lastearmen hviler mot jorden og etter at det er anbragt en støtte under lastarmens bakre del kan avmonteres ved at traktoren rygges tilbake etter at festeorganer er iløsgjort og ledningene til lastearmens hydrauliske sylinder er frakoblet. The present invention relates to tractors with a front-mounted, hydraulically raising and lowering loading arm, which after it has been lowered so that the implement placed on the loading arm rests against the ground and after a support has been placed under the rear part of the loading arm can be removed by the tractor is reversed after fastening devices have been loosened and the lines to the loading arm's hydraulic cylinder have been disconnected.
Anordninger av denne art er tidligere Devices of this kind are earlier
kjent og letter i høy grad arbeidet med på-og avmontering av lastearmen på traktoren. Når traktoren f. eks. skal anvendes for trekning kan føreren med relativt enkle håndgrep avmontere lastearmen, som ut-gjør en unyttig belastning på forhjulene og som påvirker traktorens trekkevne known and greatly facilitates the work of mounting and dismounting the loading arm on the tractor. When the tractor e.g. is to be used for pulling, the driver can remove the loading arm with relatively simple hand movements, which constitutes an unhelpful load on the front wheels and which affects the tractor's pulling ability
ugunstig ved at drivhjulene får mindre belastning og som dessuten skjermer utsik-ten for traktorføreren. Når lastearmen skal anvendes kjøres traktoren frem til denne, hvoretter nødvendige sammenkoblinger ut-føres. disadvantageous in that the drive wheels receive less load and which also shields the view for the tractor driver. When the loading arm is to be used, the tractor is driven up to it, after which the necessary connections are made.
Oppfinnelsen tar sikte på å skaffe en The invention aims to provide a
spesielt fordelaktig konstruksjon av lastearmens festeanordninger, som er slik utformet, at lastearmens hydrauliske sylin-drer kan utnyttes for å lette lastearmens av- og påmontering, og oppfinnelsen er karakterisert ved at lastearmen er festet svingbart i vertikalplanet til en i horison-talplanet U-formet ramme som omgir traktorens forende, og hvis bakre ende er løs-bart festet til traktoren, samt at rammen er forsynt med bakut åpne bøyleorganer for samvirke med på traktoren festede lagertapper eller lignende. particularly advantageous construction of the loading arm's fastening devices, which are designed in such a way that the loading arm's hydraulic cylinders can be used to facilitate the loading arm's disassembly and assembly, and the invention is characterized by the loading arm being attached pivotably in the vertical plane to a U-shaped in the horizontal plane frame that surrounds the tractor's front end, and whose rear end is releasably attached to the tractor, and that the frame is provided with hinged means open to the rear for cooperation with bearing pins or the like attached to the tractor.
På grunn av den U-formede rammen blir lastearmens festeanordning meget stabil og formbestandig og kan lett forbindes med traktorens festeører og lagertapper. Videre kan den U-formete rammen lett tilpasses de fleste traktorer, uansett om disse har smal- eller bredsporet hjul-stell foran, idet rammen er beliggende helt ovenfor forhjulene. Den kanskje største fordelen med denne konstruksjon er imidlertid at lastearmens hydrauliske sylindere kan tas til hjelp ved lastearmens av- og påmontering. Disse fordeler vil tydelig fremgå av nedenforstående beskrivelse og vedføyede tegning, som i sideriss viser et utførelseseksempel av en traktor forsynt med lastearm. Due to the U-shaped frame, the loading arm's attachment is very stable and dimensionally stable and can be easily connected to the tractor's attachment ears and bearing pins. Furthermore, the U-shaped frame can easily be adapted to most tractors, regardless of whether these have narrow- or wide-track wheel frames at the front, as the frame is situated directly above the front wheels. Perhaps the biggest advantage of this construction, however, is that the loading arm's hydraulic cylinders can be used to help with the loading arm's disassembly and reassembly. These advantages will be clearly apparent from the description below and the attached drawing, which in side view shows an example of a tractor equipped with a loading arm.
Med 10 betegnes en traktor, til hvilken det ved begge sider fast og permanent er anbragt festeører 11, f. eks. forankret i traktorens ramme. Festeørene er forsynt med et hull og med disse hull kan mot-svarende hull i den bakre ende av benene i en U-formet ramme 15 bringes til å stem-me overens, så at splinter 13 med håndtak 14 kunne føres inn gjennom hullene og feste den bakre ende av rammen 15 til traktoren. Rammen 15 består hensiktsmessig av en til U-form bokket bjelke hvis midtparti, når rammen er montert på traktoren, er beliggende foran traktorens radiator. Ved sitt midtparti er begge rammeben på undersiden forsynt med hvert sitt bakut åpne bøyleorgan 18, og når rammen er montert griper disse bøyleorganer om lagertapper 12 fast anbragte på traktoren, f. eks. dens ramme. Når rammen 15 således er montert på traktoren med splintene 13 10 denotes a tractor, to which attachment ears 11 are firmly and permanently attached on both sides, e.g. anchored in the tractor's frame. The fastening ears are provided with a hole and with these holes, corresponding holes in the rear end of the legs in a U-shaped frame 15 can be brought into agreement, so that splinters 13 with handles 14 can be inserted through the holes and attached the rear end of the frame 15 of the tractor. The frame 15 conveniently consists of a beam bent into a U-shape, the middle part of which, when the frame is mounted on the tractor, is located in front of the tractor's radiator. At their middle part, both frame legs on the underside are each provided with a rearwardly open hoop member 18, and when the frame is mounted, these hoop members grip bearing pins 12 fixed on the tractor, e.g. its frame. When the frame 15 is thus mounted on the tractor with the cotter pins 13

Ved den forreste, tverrgående del av rammen 15 er anbragt eller kan anbringes en støtte 24, fortrinnsvis formet som en omvent V, hvis ben er innrettet til å danne støtte mot jorden og som fortrinsvis kan stilles i forskjellige vinkler til hverandre. At the front, transverse part of the frame 15, a support 24 is placed or can be placed, preferably shaped like an inverted V, the legs of which are arranged to form support against the ground and which can preferably be set at different angles to each other.
På tegningen antas det ene ben å være skjult av det andre, som er vist med strek - In the drawing, one leg is assumed to be hidden by the other, which is shown with a line -

When the loading device is attached, the sequence is the opposite.
