Face shovel excavation loading device capable of improving stroke and horizontal moving requirements

Abstract

The invention provides a face shovel excavation loading device capable of improving stroke and horizontal moving requirements. A rack, a movable arm, a bucket rod, a bucket and a pair of movable arm rockers are included. The lower end of the movable arm is hinged to the rack, the upper end is hinged to one end of the bucket rod, the other end of the bucket rod is hinged to the upper portion of thebucket, and a pair of movable arm rockers are symmetrically located on the two sides of the movable arm and hinged to the middle portion of the movable arm. One ends of a pair of movable arm rockersare hinged to the rack through a pair of rack connecting rods, the other ends of a pair of movable arm rockers are hinged to the middle portion of the bucket rod through a pair of bucket rod hydrauliccylinders, the middle portion of the movable arm is hinged to the rack through a pair of movable arm hydraulic cylinders, and the lower portion of the bucket is hinged to the upper portion of the movable arm through a pair of bucket hydraulic cylinders. The provided technical scheme has the beneficial effects that the structure is simple and compact, the drive force performance of the movable armis good, the bucket stroke is obviously increased, the operation efficiency is high, and energy consumption is low.

Description

technical field [0001] The invention relates to the technical field of excavators, in particular to a front shovel digging and loading device capable of improving stroke and translation requirements. Background technique [0002] The front shovel digging and loading device is the most commonly used working device for hydraulic excavators. It mainly takes blasted rocks, ores and vertical mine faces with a certain height as the main working objects. The working conditions are harsh, and the main excavating structure is required to provide enough Large digging force and lifting force, so the front shovel digging and loading device is often used in medium and large excavators. [0003] The working device of the excavator is the main component to complete the various functions of the excavator. The research and development of large hydraulic excavators in my country started relatively late, and the domestic research results on the working device of hydraulic front shovel excavato...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the embodiment of the present invention provides a front shovel excavation loading device that can improve stroke and translation requirements, aiming at solving the problem that the common excavation loading mechanism has a small range of bucket movement and cannot meet the requirements of leveling during cargo handling and loading. Insufficient moving requirements can improve the work efficiency of excavation and loading
