Abstract

This invention relates to a device for a bucket of a digging machine, which in a usual way comprises a hydraulically operable arm, which is arranged to be detachably fastened on the bucket, the outer portion of the arm comprising a plate-formed means, which is intended to be detachably applied on an outer delimitation surface of the bucket, and a plurality of shim means being fastened on the delimitation surface and accordingly positioned between the bucket and the plate-formed means of the arm of the digging machine. According to the invention the device comprises the combination of the following features: each shim means (5) has a rectangularly or squarely designed frame (6), which is fastened on the delimitation surface (3) of the bucket (4) in a suitable way and comprises two parallel side portions (7, 8) and a third portion (9), which has a transverse direction in relation to the two first portions, and which connects the one pair of ends of the side portions (7, 8) with each other; a spacing piece (10) is insertably arranged between the side portions (7, 8) of the frame (6) and is designed in that way that it is movable within limits in a direction (V), which is essentially perpendicular to the plane of the delimitation surface (3) and accordingly the frame (6), a space being created between the delimitation surface (3) and the spacing piece (10), into which space one or more insert plates (18) are insertable; the other pair of ends of the side portions (7, 8) is connected by a detachable back piece (15), which accordingly prevents the spacing piece (10) and possible insert plates (18) from coming loose from the frame (6) of the shim means (5).

Description

15 20 25 30 506 o?9 2 utformad ram 6 innefattande två parallella sidopartier 7, 8 och ett främre parti 9 som sammanbinder sidopartiema 7, 8. Mellan sidopartierna år ett mellanstycke 10 inskjutbart anordnat. Detta mellanstycke har en sådan utformning, att dess läge relativt rampartierna kan ändras i vertikal riktning, V sett i ﬁg. 3. Dock uppvisar de båda sidopattiernas 7, 8 ovanyta inåtriktade utsprång 11, 12 (se ﬁg. 3), vilka är avsedda att kunna samverka med utåtriktade utspráng 13, 14 på respektive sidoparti 2la,b hos mellanstyckets 10 undre del, varigenom mellanstycket 10 icke kan föras ut från mellanläggsorganets 5 ram 6 i den vertikala riktningen. A frame 6 formed comprising two parallel side portions 7, 8 and a front portion 9 connecting the side portions 7, 8. Between the side portions an intermediate piece 10 is slidably arranged. This intermediate piece has such a design that its position relative to the frame portions can be changed in the vertical direction, V seen in ﬁ g. 3. can not be extended from the frame 6 of the liner 5 in the vertical direction.

Mellanlâggsorganet 5 uppvisar vid sitt bakre parti ett löstagbart bakstycke 15, som sammanbinder ramens 6 sidopartier 7, 8 och hålls samman med dessa med hjälp av två lämpliga skruvorgan 16, 17. Detta bakstycke är avsett att hålla samman mellanstycket 10 med rampartierna 7, 8, 9.The intermediate member 5 has at its rear portion a detachable back piece 15, which connects the side portions 7, 8 of the frame 6 and is held together therewith by means of two suitable screw means 16, 17. This back piece is intended to hold the intermediate piece 10 together with the frame portions 7, 8, 9.

I enlighet med vad som sagts tidigare föreligger det möjlighet till en viss rörlighet i vertikalled för mellanstycket 10 relativt de omgivande rampartierna 7, 8, 9, 15. Denna rörlighet skall sålunda medge att löstagbara skivor 18 skall kunna skjutas in under mellanstycket 10 och placeras mellan ramens 6 sidopanier 7, 8. _ I normallåge, dvs. då inga skivor 18 är insatta i mellanläggsorganet 5, är mellanstyckets 10 underyta 19 anbringad mot underlaget, dvs. gråvskopans 4 yttre begrånsningsyta, varvid mellanstyckets 10 överyta 20 ligger ungefárligen på samma nivå som överytan på sidopartíema 7, 8.In accordance with what has been said previously, there is a possibility of a certain vertical movement of the intermediate piece 10 relative to the surrounding frame portions 7, 8, 9, 15. This movement must thus allow detachable discs 18 to be slid under the intermediate piece 10 and placed between frame 6 side panels 7, 8. _ In normal position, ie. when no discs 18 are inserted in the liner 5, the lower surface 19 of the liner 10 is applied to the substrate, i.e. the outer boundary surface of the excavator 4, the upper surface 20 of the intermediate piece 10 being approximately at the same level as the upper surface of the side portions 7, 8.

Såsom visas i ñg. 3 kan emellertid mellanstyckets 10 överyta 20 höjas ovanför överytan för sidopartierna 7, 8 genom att lösa skivor 18, lämpligen gjorda av metalliskt material, inskjuts i mellanläggsorganet 5 under mellanstycket 10.As shown in ñg. 3, however, the upper surface 20 of the adapter 10 can be raised above the upper surface of the side portions 7, 8 by loosening discs 18, suitably made of metallic material, inserted into the liner 5 below the adapter 10.

Vid användning av den nya uppfinningen sker följande: De båda ramsidopanierna 7, 8 och det främre, sidopartierna 7, 8 sammanbindande rampartiet 9 hos varje mellanlåggsorgan 5 svetsas fast på grävskopans 4 yttre begränsningsyta 3. Därefter insätts mellanstycket mellan sidopartierna 7, 8 och fastsättes bakstycket 15. Vid anbringning av grävmaskinslyftarmens plattformade organ mot gråvskopans 4 yttre begränsningsyta 3 kommer sålunda det plattformade organets 2 undersida att anligga mot de ﬂertaliga mellanläggsorganen 5, vilka sålunda eliminerar eventuellt glapp mellan det plattfonnade organet 2 och grävskopans 4 yttre begränsningsyta 3. Allteftersom tiden går och grävmaskinen arbetar börjar det på nytt uppstå glapp mellan grävmaskinsarmens 1 plattformade organ 2 och grävskopan 4. I detta läge lossas det plattformade organet 2 från BNSDOCID: * ' ”see 099 3 grävskopan, varefter bakstycket 15 i mellanläggsorganet 5 lossgöres. En eller flera skivor 18 av en sådan tjocklek, att glappet mellan det plattformade organet 2 och grävskopan 4 elimineras inskjuts under rnellanstycket 10 imellanläggsorganet 5, varefter bakstycket 15 sätts tillbaka och låser fast insatsskivorna 18. I detta läge är grävrnaskinen klar för effektiv 5 användning ytterligare en tid.When using the new invention, the following takes place: The two frame side panels 7, 8 and the front, side portions 7, 8 connecting the frame portion 9 of each intermediate layer member 5 are welded to the outer limiting surface 3 of the excavator 4. Then the intermediate piece is inserted between the side portions 7, 8 and the back piece 15. When applying the platformed means of the excavator lifting arm to the outer limiting surface 3 of the excavator 4, the underside of the platformed member 2 will thus abut against the numerous intermediate members 5, which thus eliminate any play between the flatbed member 2 and the outer limiting surface of the excavator 4. When the excavator is working, a gap begins to appear again between the platform 2 of the excavator arm 1 and the excavator 4. In this position the platform member 2 is detached from the BNSDOCID: * '”see 099 3 the excavator, after which the back piece 15 of the shim 5 is detached. One or more discs 18 of such a thickness that the gap between the platform member 2 and the excavator 4 is eliminated is inserted under the runner lance 10 between the insert members 5, after which the back piece 15 is put back and locks the insert discs 18. In this position the excavator is ready for efficient use further a time.

Uppﬁnningen är naturligtvis ej begränsad till den visade och angivna utfóringsfonnen utan kan modifieras inom ramen för efterföljande patentkrav. -miíï--ï-m-í--xï-.ï BNSDOCID: The invention is of course not limited to the embodiment shown and stated but can be modified within the scope of the appended claims. -miíï - ï-m-í - xï-.ï BNSDOCID:
