Abstract

The invention discloses a motion redundancy face shovel excavating mechanism capable of optimizing lifting force, wherein a movable arm is hinged with a frame; a hopper rod is hinged with the movable arm; a bucket is hinged with the hopper rod; the frame, the movable arm, the hopper rod and the bucket form an open type tandem connection chain; a powerful triangle is hinged with the movable arm, the end part of the cylinder sleeve of the bucket hydraulic cylinder is hinged with the bucket, and the end part of the piston rod of the bucket hydraulic cylinder is hinged with the powerful triangle; the end part of the cylinder sleeve of the hopper rod hydraulic cylinder is hinged with the hopper rod, and the end part of the piston rod of the hopper rod hydraulic cylinder is hinged with the movable arm; the end part of the cylinder sleeve of a driving arm hydraulic cylinder is hinged with the powerful triangle, and the end part of the piston rod of a main driving arm hydraulic cylinder is hinged with the frame; and the end part of the cylinder sleeve of an auxiliary driving arm hydraulic cylinder is hinged with the powerful triangle, and the end part of the piston rod of the auxiliary driving arm hydraulic cylinder is hinged with the frame. The motion redundancy face shovel excavating mechanism provided by the invention has the characteristics of motion redundancy, large driving force arm, excellent flexibility and optimized input force.

Description

technical field [0001] The invention relates to an excavator, in particular to a working mechanism for a front shovel hydraulic excavator. Background technique [0002] Large-scale front shovel hydraulic excavator is the main tool for mining in open-pit coal mines, and its excavating working device is the main component to complete various functions of the excavator. There are few domestic studies on the working device of hydraulic front shovel excavator. Chinese patent CN200520035287.8 involves a A horizontal pushing mechanism of a front shovel operation device of a hydraulic excavator, characterized by the hinged bucket hydraulic cylinder piston rod and the front end of the boom, the hinged rear part of the stick with the front end of the boom, the hinged bucket with the front end of the stick, and the hinged bucket with the bucket. The ends of the cylinder barrel of the hydraulic cylinder are hinged, and the hinge points form a four-bar mechanism with a quadrilateral stru...
