Double-rocker lengthened working device for hydraulic excavator
The invention discloses a double-rocker lengthened working device for a hydraulic excavator. The double-rocker lengthened working device comprises a bucket rod and a bucket cylinder. The rear end of the bucket cylinder is hinged to the rear end of the bucket rod through a pin shaft. The double-rocker lengthened working device further comprises a push rod, a front rocker and a rear rocker. The axial rear end of the push rod is connected with the front end of the bucket cylinder. The upper end of the front rocker is hinged to the front end of the push rod. The lower end of the front rocker is hinged to the bucket rod. The upper end of the rear rocker is hinged to the rear end of the push rod. The lower end of the rear rocker is hinged to the bucket rod. The push rod, the front rocker, the rear rocker and the bucket rod jointly form a double-rocker mechanism. The double-rocker lengthened working device can adapt to working conditions of various lengthened working devices, the hydraulic cylinder can be protected, the force condition of structural parts of the working device can be improved, and the working performance of the excavator can be improved.
