A quick coupler ( 20 ) for coupling a hydraulically operated tool/implement ( 10 ) onto an excavator boom provided with a tilt rotator ( 1 ) and a bucket latch ( 5 ), comprising a mechanical coupling member ( 21 ) adapted to be fixedly mounted onto the tool/implement and designed to be secured to the tilt rotator by means of the bucket latch, a first valve block ( 27 ) for hydraulics, the valve block being adapted to be fixedly mounted onto the tilt rotator, and a second valve block ( 28 ) movably mounted onto the mechanical coupling member, and arranged to be displaced by the bucket latch when the bucket latch secures the tool/implement to the tilt rotator, into contact with the first valve block, such that the two valve blocks are interconnected to allow the flow of hydraulic fluid therethrough, and a mechanical coupling member ( 21 ) adapted to be fixedly mounted onto the tool/implement. |
