Abstract

The invention discloses a face shovel excavation device for optimizing lifting force of a movable arm. The lower end of the movable arm is hinged with a machine frame, and the upper end of the of the movable arm is hinged with one end of a bucket rod; the other end of the bucket rod is hinged with the upper part of a shovel bucket, and the lower part of the shovel bucket is hinged with one end of a pair of shovel bucket hydraulic cylinders; the middle part of the bucket rod is hinged with one end of a pair of bucket rod hydraulic cylinders, and the other end of the pair of bucket rod hydraulic cylinders is hinged with the machine frame; and one end of a pair of machine frame connecting rods is hinged with the machine frame. The face shovel excavation device is characterized in that one end of a pair of movable arm hydraulic cylinders is hinged with the movable arm through a pair of movable arm rockers, or one end of the pair of movable arm hydraulic cylinders is hinged with the movable arm through the pair of machine frame connecting rods and the pair of movable arm rockers; the other end of the pair of movable arm hydraulic cylinders is hinged with the machine frame; and the other end of the pair of shovel bucket hydraulic cylinders is hinged with the pair of movable arm rockers or the pair of machine frame connecting rods or the movable arm. According to the face shovel excavation device, the stress on all the components is uniformly distributed, the energy consumption is reduced, the lifting force of the movable arm can be optimized, and the face shovel excavation device is compact in structure and has a wide application prospect.

Description

technical field [0001] The invention relates to an excavator, in particular to a working device for a front shovel hydraulic excavator. Background technique [0002] The 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 researches on the working device of the hydraulic front shovel excavator. Chinese patent CN200520035287.8 relates to a horizontal pushing device of a hydraulic excavator front shovel operation device, which is characterized in that the piston rod of the bucket cylinder is hinged to the front end of the boom, the rear part of the stick is hinged to the front end of the boom, and the bucket is hinged to the front end of the stick , the bucket is hinged to the end of the bucket oil cylinder, and the hinge points form a four-bar device with a quadrilateral structure in the air. Chinese pat...
