The invention relates to an excavator accessory quick-change connector. The excavator accessory quick-change connector comprises a connector body, wherein the upper end of the connector body is hinged to an excavating arm of an excavator through an excavating arm pin, the upper end of the connector body is hinged to a connecting rod mechanism through a connecting rod pin, an excavator bucket oil cylinder of the excavator drives the connector body to rotate with the excavating arm pin as a shaft core through the connecting rod mechanism, a latch hook mechanism comprising a fixed latch hook, a sliding latch hook and a bayonet lock is arranged at the bottom of the connector body, the sliding latch hook is assembled in a sliding mode in the left-right direction, and the hook parts of the fixed latch hook and the sliding latch hook penetrate through the space between two accessory pins of the excavator bucket to be locked. According to the excavator accessory quick-change connector, the clamping pin is assembled on the connector body in a penetrating mode in the front-back direction and used for limiting and fixing the sliding latch hook with the locked accessory pin, through locking of the sliding latch hook and limiting and fixing of the bayonet lock, operation is easy, light and fast, the locking force is large, the shaking probability of the excavator bucket is effectively reduced, abrasion among all components is effectively reduced, and the use stability is improved.
本发明涉及一种挖掘机属具快换接头，它包括接头主体，该接头主体的上端通过挖臂销与挖掘机的挖臂铰接，该接头主体的上端通过连杆销铰接有连杆机构，挖掘机的挖斗油缸通过该连杆机构驱动接头主体以挖臂销为轴芯转动；该接头主体的底部设有包括固定锁钩、滑动锁钩和卡销的锁钩机构；该滑动锁钩沿左右方向滑行地装配；固定锁钩和滑动锁钩的钩部由挖斗的两个属具销之间穿过锁紧；该卡销由前后方向穿行装配于接头主体，用于对已锁紧属具销的该滑动锁钩限位固定。通过滑动锁钩的锁紧和卡销的限位固定，操作简单轻便快捷，且锁紧力度大，有效减少挖斗晃动概率，进而有效减少各部件之间的磨损，提高使用稳定性。
