Definitions

• the present invention relates to a guick-coupling arrangement for effecting connection of an implement to an excavating machine, digger or like machine while also affection of the implement to a power system at the same time .
• hydraulic quick-coupling devices are often used for coupling and connecting the implements directly from the driving cabin during the excavation work.
• That part of the ma ⁇ chine which is pivotally connected to the digging arm and the shovel or implement link is provided with one or more connecting and coupling parts, for instance female-type hydraulic couplings.
• the implement to be coupled to this part is provided with corresponding male-type hydraulic couplings.
• the couplings have been positioned in a pro ⁇ tected place in the quick-coupling arrangement itself and the connection is arranged so that when the quick- coupling moves in an implement coupling or implement uncoupling direction, the hydraulic couplings which are operative in powering movement of the implement will be connected or disconnected at the same time.
• a driver is able to connect or disconnect an implement directly from the driving cabin of an exca ⁇ vating machine and the hydraulic system will be con ⁇ nected or disconnected at the same time as the quick- coupling is used to connect or disconnect the imple ⁇ ment.
• Fig. 1 is in accordance with the invention a side viewofthe upper part ofan implement, forinstance a digging shovel having a hydraulic connection on the roof of the shovel, and a digging arm which is connected to a digging shovel.
• Figure 2 illustrates in accordance with the invention a shovel quick-coupling which incorporates hose couplings.
• the illustrated implement quick-coupling arrangement for excavating machines in accordance with the inven ⁇ tion includes a hydraulic connection and is manoeu- vered hydraulically.
• the illustrated quick- coupling arrangement l may be manoeuvered manually or electromagnetically.
• the quick-coupling arrangement includes one or more hydraulic hose couplings, wherein a female part of one hydraulic hose coupling is fixedly mounted on a movable part which accompanies the movement of the locking mechanism 6 in the quick-coupling arrange ⁇ ment. Hydraulic quick-couplings 8 may be placed on both sides of the hydraulic piston-cylinder device 7 within the quick-coupling so as to be protected to the best possible extent.
• Corresponding hose coupling parts or implement (shovel) coupling parts, male parts 9, are mounted firmly on the implement, e.g. the bucket or shovel, with the aid of an attachment 11 such that the coup ⁇ ling parts will take positions that are suitable for receiving the female part 8 when the quick-coupling arrangement 1 is firmly locked to the bucket or shov ⁇ el.
• a ⁇ the locking mechanism 6 of the quick-coupling 1 arrangement is activated so as to hold the bucket or shovel firmly, female parts 8 are, at the same time, moved in parallel over male parts 9 and are automati- cally locked in a fully inserted position by locking mechanisms 10 incorporated in the female couplings.
• Coupling of the implement and coupling of the hydrau ⁇ lics are thus effected at one and the same time.
• the locking mechanism 6 of the quick- coupling arrangement is activated in the opposite direction and, at the same time, the locking mechanism 10 of the female part 8 is released and the female part moved from its coupled position, therewith disen- gaging the implement and the hydraulic coupling simul ⁇ taneously.
• the implement need not be provided with actual hydraulic hoses but can be connected directly to a power cylinder or the like while the hydraulic connections in the shovel quick-coupling arrangement obtain a small movement area and are well protected from above and from the side of the actual implement coupling.
• the locking mechanism moves in a straight line so as to grip and accurately fixate the rear implement bolt
• the hydrau ⁇ lic hose couplings will move forwards under power and will accompany said movement in parallel, therewith achieving extremely good alignment and guiding of the couplings towards the couplings on the implement, therewith connecting the implement hydraulically to the excavator in a reliable and safe fashion.
