Mining excavator bucket opening mechanism and excavator
The bucket opening mechanism comprises a driving part, a steel wire rope, a lever, a chain and a bucket bolt, the driving part is arranged on an A-shaped frame of the excavator, one end of the lever is hinged to a bucket rod of the excavator, the bucket bolt is arranged on a bucket of the excavator, one end of the steel wire rope is connected with the driving part, and the other end of the steel wire rope is connected with the chain. One end of the chain is connected to the lever, and the other end of the chain is connected with the bucket bolt; the driving part comprises a support, a motor, a winding drum shaft, a winding drum, a gear and an inner gear ring, the motor is an alternating-current variable-frequency motor arranged on the support, the winding drum shaft is arranged on the support and is in the same direction as an output shaft of the motor, the winding drum is rotatably arranged on the winding drum shaft in a sleeving mode, and the gear is arranged on the output shaft of the motor in a sleeving mode. When the motor rotates, the gear and the inner gear ring are kept in an engaged state so as to drive the winding drum to rotate around the winding drum shaft. The driving process is stable and reliable, and large impact is avoided.
本发明公开了一种矿用挖掘机开斗机构及挖掘机，该开斗机构包括：驱动件、钢丝绳、杠杆、链条和斗栓，驱动件设置在挖掘机的A型架上，杠杆的一端铰接在挖掘机的斗杆上，斗栓设置在挖掘机的铲斗上，钢丝绳的一端与驱动件连接，另一端连接在杠杆上，链条的一端连接在杠杆上，另一端与斗栓连接；驱动件包括：支架、电动机、卷筒轴、卷筒、齿轮和内齿圈，电动机为设置在支架上的交流变频电动机，卷筒轴设置于支架上且与电动机的输出轴同向，卷筒可转动地套设在卷筒轴上，齿轮套装在电动机的输出轴上，内齿圈设置在卷筒侧面并与齿轮啮合，电动机转动时，齿轮和内齿圈保持啮合状态以驱动卷筒绕卷筒轴转动。驱动过程稳定可靠，避免产生较大冲击。
