Further, rocker arm swing rod is arc-shaped, be respectively equipped on rocker arm swing rod the first work axis hole, second work axis hole,
Third work axis hole, three work axis hole settings triangular in shape；The piston rod earrings of bucket arm cylinder passes through rocker arm intermediate vertex pair
The the second work axis hole and rocker arm swing rod answered are hinged.
Further, the first work axis hole of rocker arm swing rod passes through the rocker bearing seat and excavator of excavator swing arm front end
Power arm front is hinged, and rocker bearing seat is located at the top surface, side or bottom surface of excavator swing arm front end.
The device have the advantages that：
The present invention is equipped with rocker arm swing rod, dipper push rod, rocker bearing seat, is respectively equipped with three working shafts above rocker arm swing rod
Hole, three work axis hole settings triangular in shape, the first work axis hole and rocker bearing seat axis hole of rocker arm swing rod are hinged, rocker arm shaft
The front end that seat is located at excavator swing arm is held, the first shaft hole of third the work axis hole and dipper push rod of rocker arm swing rod is hinged, dipper
Second axis hole of push rod and the power arm of dipper are hinged；Piston rod earrings and rocker arm swing rod second the work axis hole hinge of bucket arm cylinder
It connects, bucket arm cylinder drives dipper rotation by driving rocker arm swing rod, dipper push rod.Compared with prior art, the present invention is additionally arranged
Rocker arm swing rod, dipper pusher structure, bucket arm cylinder drive dipper rotation by driving rocker arm swing rod, dipper push rod, effectively solve
Dipper digging force is small, and bucket arm cylinder stroke is big, bucket arm cylinder cylinder diameter is big, working hydraulic pressure oil pressure is big, bucket arm cylinder and dipper
Easily form dead point, the slow problem of excavation speed.Compared with prior art, bucket arm cylinder impulse stroke of the present invention can shorten a quarter
Left and right, dipper digging force can increase a quarter or so, and the excavation speed of dipper accelerates a quarter or so, while also reaching drop
Low in-oil cylinder hydraulic fluid pressure, fuel-economizing effect.
Detailed description of the invention
