Description

Foreliggende oppfinnelse angår en lastemaskin av den The present invention relates to a loading machine thereof

type som omfatter et kjøretøy og en hev- og senkbar, samt tipp- type that includes a vehicle and a lifting and lowering bar, as well as tipping

bar lasteskuffe. Det er kjent ved lastemaskiner å anordne en graveskuffe til å føre masse ned på et transportorgan som fører den utgravede masse bort. Det er også kjent å forsyne en lastemaskin med en separat skjærkant for å lette utgraving av massen. Maskinen ifølge oppfinnelsen skiller seg fra tidli- bare cargo tray. It is known for loading machines to arrange a digging bucket to lead mass down onto a transport device which carries the excavated mass away. It is also known to provide a loader with a separate cutting edge to facilitate excavation of the mass. The machine according to the invention differs from previous

gere kjente maskiner ved at en skuffe er svingbart forbundet med lasteskuffen. Denne forbindelse er utført slik at skuffen i sin ene sluttstilling befinner seg i lasteskuffen og derved er rettet i samme retning som lasteskuffen. Ved denne anordning oppnås en vesentlig økning av lastekapasiteten samtidig som kjøretøyet kan dimensjoneres for bare lasteskuffen. Når skuffen er fylt og sperret i hevet stilling av et på kjøretøyet fore- known machines in that a drawer is pivotably connected to the loading drawer. This connection is made so that the drawer in its one end position is in the loading drawer and is thereby directed in the same direction as the loading drawer. With this device, a significant increase in load capacity is achieved while the vehicle can be dimensioned for just the load box. When the bucket is filled and locked in the raised position by a device on the vehicle

liggende hakesperreorgan, lettes fyllingen av lasteskuffen, fordi tyngden av den fylte skuffe innvirker fordelaktig på det forreste hjulpars drivevne. Oppfinnelsen utmerker seg ved de karakteris- horizontal chin locking device, the filling of the cargo tray is facilitated, because the weight of the filled tray has a beneficial effect on the driving ability of the front pair of wheels. The invention is distinguished by the characteristic

muliggjøre denne-form for styring har kjøretøyet 1 sentrale ledd 43, 44. Da kjøretøyets konstruktive utformning ikke ut-gjør noen del av oppfinnelsen, skal det heller ikke beskrives nærmere her. enable this form of steering, the vehicle 1 has central links 43, 44. As the vehicle's constructive design does not form any part of the invention, it shall not be described in more detail here either.

Lastemaskinen er forsynt med to armer 4, 5 som er svingbart forbundet med kjøretøyet 1 ved hjelp av ledd 22, hvorav bare ett er vist. En lasteskuffe 2 er svingbart båret av armene 4, 5 ved hjelp av ledd 32, hvorav ett er vist. For heving og senking av lasteskuffen 2 er lastemaskinen forsynt med to hydrauliske sylindere 16, 17. Sylinderne 16, 17 er forbundet med armene 4, 5 ved hjelp av sylindriske tapper 20, 21. De hydrauliske sylindere 16, 17 er dessuten forbundet med på kjøretøyet 1 foreliggende festeorganer 18, 19 forsynt med tapper. For tipping av lasteskuffen 2 om leddene 32 er lastemaskinen forsynt med hydrauliske sylindere 26, 27. Disse er forbundet med lasteskuffen 2 ved hjelp av ledd 30, 31. De hydrauliske sylindere 26, 27 er dessuten forbundet med festeorganer 28, 29 forsynt med tapper og.montert på fremspring 24, 25 på armene 4, 5. Lasteskuffen 2 er ved sin mot kjøretøyet 1 vendende side forsynt med to fremspring 8, 9 som ved hjelp av ledd 10, 11 er forbundet med fremspring 6, 7 på en skuffe 3. Mellom fremspringene 6, 7 på skuffen er anordnet en sylindrisk stang 12. En sperrehakeinnretning 13 er ved hjelp av en aksel 14 forbundet med et på kjøretøyet 1 foreliggende festeorgan 15. Sperrehaken 13 er beregnet på sam-virke med stangen 12 for opphaking av skuffen 3. For det formål å oppnå en enkel automatisk opphaking av skuffen er krokens 13 aksel 14 slik anbragt at kroken 13 under innvirkningen av tyngdekraften føres mot sluttstillingen 42, hvori opphakning av skuffen 3 finner sted. Lasteskuffen 2 er slik utformet at skuffen 3 i sin ene sluttstilling befinner seg i■lasteskuffen 2. Skuffen 3 er derved rettet i samme retning som lasteskuffen. Denne stilling er på fig. 6 gitt betegnelsen 33. Når lasteskuffen 2 heves, slik at skuffen 3 føres fra stillingen 34, foregår en automatisk opphakning av skuffen 3. Denne opphakning. foregår ved at stangen 12 fører kroken 13 bort fra opphakningsstillingen 42 som vist på fig. 6. Når stangen 12 har passert kroken 13, svin-ger denne ved tyngdekraftens virkning tilbake til opphakningsstillingen 42. Skuffens 3 stilling 35 tilsvarer den stilling skuffen inntar på fig. 3. The loading machine is provided with two arms 4, 5 which are pivotally connected to the vehicle 1 by means of link 22, only one of which is shown. A loading drawer 2 is pivotably carried by the arms 4, 5 by means of joints 32, one of which is shown. For raising and lowering the loading tray 2, the loading machine is equipped with two hydraulic cylinders 16, 17. The cylinders 16, 17 are connected to the arms 4, 5 by means of cylindrical pins 20, 21. The hydraulic cylinders 16, 17 are also connected to the vehicle 1 present fastening means 18, 19 provided with studs. For tipping the loading tray 2 about the joints 32, the loading machine is provided with hydraulic cylinders 26, 27. These are connected to the loading tray 2 by means of joints 30, 31. The hydraulic cylinders 26, 27 are also connected with fastening means 28, 29 provided with pins and .mounted on protrusions 24, 25 on the arms 4, 5. On its side facing the vehicle 1, the loading drawer 2 is provided with two protrusions 8, 9 which are connected by means of joints 10, 11 to protrusions 6, 7 on a drawer 3. A cylindrical rod 12 is arranged between the projections 6, 7 on the bucket. A locking hook device 13 is connected by means of a shaft 14 to a fastening device 15 present on the vehicle 1. The locking hook 13 is designed to cooperate with the rod 12 for picking up the bucket 3 For the purpose of achieving a simple automatic pick-up of the bucket, the hook 13's shaft 14 is arranged so that the hook 13 is moved under the influence of gravity towards the end position 42, in which pick-up of the bucket 3 takes place. The loading drawer 2 is designed so that the drawer 3 in its one end position is located in the loading drawer 2. The drawer 3 is thereby directed in the same direction as the loading drawer. This position is shown in fig. 6 given the designation 33. When the loading drawer 2 is raised, so that the drawer 3 is moved from the position 34, an automatic pick-up of the drawer 3 takes place. This pick-up. takes place by the rod 12 leading the hook 13 away from the hooking position 42 as shown in fig. 6. When the rod 12 has passed the hook 13, this swings back to the hooking position 42 under the action of gravity. The position 35 of the drawer 3 corresponds to the position the drawer takes in fig. 3.

Den på tegningen viste lastemaskin er beregnet på an-vendelse på følgende måte. I utgangsstillingen befinner skuffen 3 seg i lasteskuffen 2. Deretter fylles skuffen 3,og lasteskuffen 2 heves så meget at skuffen 3 hakes opp av kroken 13.- Denne stilling er vist på fig. 1. Deretter senkes lasteskuffen 2 til den på fig. 2 viste stilling og fylles. Deretter heves lasteskuffen 2 til den på fig. 3 viste stilling, hvorved skuffen 3 heves ytterligere av lasten i lasteskuffen 2, slik at stangen 12 ikke lenger samvirker med kroken 13. Lastemaskinen kjøres deretter til en tømmeplass, hvor lasteskuffen 2 ved påvirkning av de hydrauliske sylindere 26, 27 tippes om leddene 32. Denne stilling er vist på fig. 4. Når godset forsvinner ut av lasteskuffen 2, svinges skuffen 3 om leddene 10, 11 inn i lasteskuffen 2 og tøm-mes. For å lette tømmeprosessen kan de hydrauliske sylindere 26, 27 eller de hydrauliske sylindere 16, 17 eller eventuelt samt-lige sylindere mates med hydraulisk væske, hvis trykk pulserer slik at lasteskuffen 2 og skuffen 3 utsettes for vibrasjon. Lastemaskinen er dessuten hensiktsmessig forsynt med organer som hin-drer at skuffen 3 tipper over mot førerkabinen. The loading machine shown in the drawing is intended for use in the following way. In the initial position, the drawer 3 is in the loading drawer 2. The drawer 3 is then filled, and the loading drawer 2 is raised so much that the drawer 3 is caught by the hook 13. - This position is shown in fig. 1. Then lower the loading drawer 2 to the one in fig. 2 shown position and is filled. The loading drawer 2 is then raised to the one in fig. 3 position, whereby the bucket 3 is further raised by the load in the loading bucket 2, so that the rod 12 no longer cooperates with the hook 13. The loading machine is then driven to an emptying place, where the loading bucket 2 is tipped over the joints 32 by the influence of the hydraulic cylinders 26, 27. This position is shown in fig. 4. When the goods disappear from the loading drawer 2, the drawer 3 is swung around joints 10, 11 into the loading drawer 2 and emptied. To facilitate the emptying process, the hydraulic cylinders 26, 27 or the hydraulic cylinders 16, 17 or possibly all cylinders can be fed with hydraulic fluid, the pressure of which pulsates so that the loading drawer 2 and drawer 3 are exposed to vibration. The loading machine is also appropriately equipped with devices that prevent the tray 3 from tipping over towards the driver's cabin.
