Abstract

The present invention relates to an excavator device. For the purpose of allowing fast and efficient tool change directly from the driver's cab and of being able to drive a plurality of tools at the same time, the device according to the invention is characterized in that tool holders 5, which have been matched to different tools 4, are detachably fastened to the body 1 of the excavator, and in that the tools, by means of preferably double- acting hydraulic cylinders acting upon the mounting bolts of the tools, are arranged to be coupled to the arm 3 of the excavator. <IMAGE>

Description

seo1sss-9 É 2 bultar är anordnade att kopplas till grävmaskinens arm genom att redskapshål- larna enkeltvis kan skjutas ut_från grävmaskinskroppen medelst en hydraulisk cylinder fäst vid grävmaskinens chassi, så att grävmaskinskroppen med redskaps- hållarna kan vridas utan att komma i beröring med en stillastående utskjuten redskapshållare. * ~Ett utföringsexempel på uppfinningen visas på ritningen, i vilken figur 1 är en sidovy av en grävmaskin med en anordning enligt uppfinningen, figur 2 visar grävmaskinen vid redskapsbyte, och figur 3 är en planvy av grävmaskinen. ._ På ritningen anger 1 grävmaskinens vridbara kropp. 2 och 3 är maskinens grävarm och 4 betecknar ett grävredskap. 5 är redskapshöllare och 6 är en hydraulisk arm som är fäst vid grävmaskinens chassi 7 och som därför inte kan vridas med grävmaskinskroppen 1. I figur 2 har en redskapshållare 5 skjutits ut från grävmaskínskroppen 1. Grävmaskinens framdrift sker medelst larvband 8. ' Ånordningens funktion är som följer: När grävmaskinsföraren vill byta red- skap 4 vrider han grävmaskinskroppen 1 så att deh hydrauliska armen 6 kommer över en tom redskapshållare 5 för det redskap han för tillfället.använder. seo1sss-9 É 2 bolts are arranged to be connected to the excavator arm by the tool holders can be individually slid out of the excavator body by means of a hydraulic cylinder attached to the excavator chassis, so that the excavator body with the implement holders can be rotated without coming into contact with tool holder. An embodiment of the invention is shown in the drawing, in which figure 1 is a side view of an excavator with a device according to the invention, figure 2 shows the excavator when changing implements, and figure 3 is a plan view of the excavator. ._ In the drawing, 1 indicates the rotatable body of the excavator. 2 and 3 are the digging arm of the machine and 4 denotes a digging tool. 5 is an implement holder and 6 is a hydraulic arm which is attached to the excavator chassis 7 and which therefore cannot be rotated with the excavator body 1. In figure 2 an implement holder 5 has been pushed out from the excavator body 1. The excavator is propelled by means of caterpillar tracks 8. The function of the device is as follows: When the excavator operator wants to change implement 4, he turns the excavator body 1 so that the hydraulic arm 6 comes over an empty implement holder 5 for the implement he is currently using.

Därefter skjutes den tomma redskapshällaren 5 medelst armen 6 ut från sina fäst- organ på maskinkroppen1sâ långt att kroppen 1 med redskapshöllare 5 kan svänga fritt från den utskjutna redskapshâllaren 5. Hydraularmen 6 är försedd med fäst- " organ (ej visade) som ingriper med motsvarande fästorgan på den hållare 5 som skjutes ut. Därefter vrides maskinens kropp 1 180° och operatören placerar det redskap han önskar byta ut i den tomma redskapshållaren 5. Redskapet 4 fri- göres från grävarmen 3 medelst hydraulcylindrar vars kolvstänger tjänar som fästbultar. Därefter vrides maskinkroppen 1 på nytt 180° och hydraularmen 6 dras in så att redskapshållarens 5 fästorgan ingriper med motsvarande fästorgan på kroppen 1. Efter det kroppen 1 vrídits så att hydraularmen 6 kommer över redskapshållaren 5 med det redskap som operatören önskar använda, skjutes den hydrauliska armen 6 på nytt ut så att ifrågavarande hållare medbringas. Där- efter vrides kroppen 1 ca. 1800, aph grävarmen 3 kopplas till det nya redskapet medelst hydrauliska cylindrar. Då varje redskapshällare är anpassad till ett bestämt redskap, kommer kopplingsfästena på grävmaskinsarmen 3 alltid att passa till motsvarande kopplingsfästen på redskapet när armen 3 är placerad i läge för tillkoppling. Efter upplyftning av det tillkopplade redskapet från hållaren 5 vrides kroppen 1 ca. 180° och den tomma hàllaren dras in med hjälp av armen 6 och fästes vid kroppen 1. Maskinen är nu klar att arbeta med det nya redskapet.Then the empty tool holder 5 is pushed out by means of the arm 6 from its fastening means on the machine body 1 so far that the body 1 with tool holder 5 can pivot freely from the extended tool holder 5. The hydraulic arm 6 is provided with fastening means (not shown) which engage with corresponding fastening means on the holder 5 which is pushed out.Then the body of the machine is turned 180 ° and the operator places the tool he wishes to replace in the empty tool holder 5. The tool 4 is released from the digging arm 3 by means of hydraulic cylinders whose piston rods serve as mounting bolts. 1 again 180 ° and the hydraulic arm 6 is retracted so that the attachment means of the implement holder 5 engages with corresponding attachment means on the body 1. After the body 1 has been rotated so that the hydraulic arm 6 comes over the implement holder 5 with the implement which the operator wishes to use, the hydraulic arm 6 is pushed on new so that the holder in question is brought in. Then the body 1 is turned approx. 1800, aph the digging arm 3 is connected to the new implement by means of hydraulic cylinders. When each implement holder is adapted to a specific implement, the coupling brackets on the excavator arm 3 will always fit the corresponding coupling brackets on the implement when the arm 3 is placed in the position for coupling. After lifting the connected implement from the holder 5, the body 1 is turned approx. 180 ° and the empty holder is retracted using the arm 6 and attached to the body 1. The machine is now ready to work with the new implement.

Genom att använda en anordning enligt uppfinningen kan grävmaskinen trans- portera med sig flera redskap och dessutom kan byte ske snabbt och lätt. Genom byte till rätt redskap för varje arbetsoperation, ökar grävmaskinens effektivi- tet betydligt.By using a device according to the invention, the excavator can transport several implements with it and in addition, replacement can take place quickly and easily. By changing to the right tool for each work operation, the efficiency of the excavator increases significantly.

s 8001855-9 Vid lyft kan t.ex. grüvredskapet 4 bytas ut mot en hydraulisk hiss. Idag användes en kätting som är fäst vid grävredskapet. Genom att byta ut grävred- skapet erhålles en väsentligt större lyftkratt. Om så önskas kan till armen 3 anslutas en förlängningsbom. Då redskapshöllarna företrädesvis är fästa på grävmaskinskroppen 1 på mot- satt sida om grävarmen 3, fungerar de längs kroppen 1 fästa redskapen som mot- vikt, varvid maskinen får större stabilitet. Patentkrav:s 8001855-9 When lifting, e.g. the excavating tool 4 is replaced by a hydraulic lift. Today, a chain attached to the excavator was used. By replacing the digging implement, a significantly larger lifting rake is obtained. If desired, an extension boom can be connected to the arm 3. Since the implement holders are preferably attached to the excavator body 1 on the opposite side of the excavator arm 3, the attachments along the body 1 function as a counterweight, whereby the machine has greater stability. Claims: 1.
