Abstract

The invention discloses a three-degree-of-freedom twelve-rod hydraulic excavator. The hydraulic excavator comprises a rack, a movable arm, a bucket rod, a bucket, symmetrically-installed rocker arms,rocker arm connecting rods, movable arm hydraulic cylinders, bucket rod hydraulic cylinders and bucket hydraulic cylinders; the movable arm is hinged to the rack, the rocker arms and the bucket rod separately; one ends of the rocker arm connecting rods are hinged to the bucket rod, and the other ends of the rocker arm connecting rods are hinged to the rocker arms; the two ends of the movable hydraulic cylinders are hinged to the rack and the movable arm; the two ends of the bucket rod hydraulic cylinder are hinged to bucket rod hinge lugs and movable arm hinge lugs; one ends of the bucket hydraulic cylinders are hinged to the bucket, and the other ends of the bucket hydraulic cylinders are hinged to the rocker arms. By additionally arranging the rocker arm connecting rods and the rocker arms, the flexibility of the bucket output track is enhanced, the digging force target is improved, and the working efficiency is high.

Description

technical field [0001] The invention relates to the field of engineering excavators, in particular to a three-degree-of-freedom twelve-rod hydraulic excavator for improving work efficiency, enhancing the flexibility of bucket output trajectory, and realizing the goal of improving digging force. Background technique [0002] Hydraulic excavators are widely used in mechanized construction such as construction and transportation industries, farmland transformation, water conservancy and hydropower, mining and modern military engineering because of their simple structure and the ability to achieve relatively complex actions. During the operation of the excavator, as the working environment becomes more and more complex, the requirements for the digging force of the excavator become higher and higher. The traditional hydraulic excavator realizes the path output of the root of the bucket on the plane through the combined drive of the boom hydraulic cylinder and the stick hydraulic...
