Abstract

The invention discloses a three-degree-of-freedom fourteen-rod hydraulic excavator. The excavator comprises a rack, a movable arm, a bucket rod, a bucket, a first rocker arm, a second rocker arm, a first rocker arm connecting rod, a second rocker arm connecting rod, a movable arm hydraulic cylinder, a bucket rod hydraulic cylinder and a bucket hydraulic cylinder; the movable arm is hinged to the rack, the first rocker arm, the second rocker arm and the bucket rod; the two ends of the first rocker arm connecting rod are hinged to the rack and the first rocker arm; the two ends of the second rocker arm connecting rod are hinged to the bucket rod and the second rocker arm; the two ends of the movable arm hydraulic cylinder are hinged to the rack and the first rocker arm; the two ends of the bucket rod hydraulic cylinder are hinged to a bucket rod hinge lug and the first rocker arm; and the two ends of the bucket hydraulic cylinder are hinged to the bucket and the second rocker arm. According to the excavator, the flexibility of the output track of the bucket can be enhanced, the target of the excavation force is improved, and the structure is simple and compact.

Description

Technical field [0001] The invention relates to the field of engineering excavators, in particular to a three-degree-of-freedom fourteen-bar hydraulic excavator used to improve work efficiency, enhance the flexibility of bucket output trajectory, and achieve the goal of improving digging force. Background technique [0002] Hydraulic excavators are widely used in mechanized construction such as construction and transportation industries, farmland reconstruction, water conservancy and hydropower, mining and modern military engineering, due to their simple structure and more complex actions. In the process of excavator operation, as the operating environment becomes more and more complex, the requirements for the excavator's digging force become higher and higher. The traditional hydraulic excavator realizes the trajectory output of the bucket root on the plane through the joint drive of the boom hydraulic cylinder and the stick hydraulic cylinder, and then is driven by a separate ...
