Abstract
PURPOSE:To rapidly attach and detach an earth-moving device to and from a Z-bar linkage type earth-moving vehicle, by a method wherein a pipe member at an upper hitch part engages hook parts at an upper part of the back of a working device, and a lateral frame of a lower hitch part mates protruding parts at the hook part of the lower part of the back of the working device. CONSTITUTION:In a quick coupler which attaches a working device, such as a bucket 40, to a lift arm 36, a hitch 2 is pivotably secured to the forward end of the lift arm 36 to rock it by means of a tilt link 38. Upper hook parts 44 and lower parts 42 are mounted to the rear part of the bottom plate of the bucket 40. A pipe member 30 at the upper part 44, and a lateral frame 6 at the lower part of the hitch 2 mates protruding parts 54 at the lower hook part 42 of the bucket 40 to secure them by means of a bin.
