Quick coupling

The invention relates to a coupling for securing an accessory to an earthmoving machine. The coupler includes a coupler body that presents a socket having a capture area. The pin of the accessory can be moved into and out of the capture area. A retainer may capture the pin in the capture region, but the retainer may be moved by a hydraulically driven driver to a position that allows release of the pin from the capture region. A trigger that the pin will strike when the pin is moved into or out of the capture area discouples the driver from the retainer and then allows the retainer to be biased back to its retaining position by a spring. 本发明涉及一种用于将附件固定到土方机器的联接器。所述联接器包括联接器主体，所述联接器主体呈现具有捕获区域的插座。附件的销可以移入和移出所述捕获区域。保持器可以在所述捕获区域中捕获所述销，但是所述保持器可以由液压地驱动的驱动器移动到允许从所述捕获区域释放所述销的位置。当所述销移入或移出所述捕获区域时所述销将撞击的触发器将所述驱动器与所述保持器解除联接，并且随后允许所述保持器通过弹簧偏置回到其保持位置。
