Abstract

The invention discloses a spatial excavator with a two-range-of-motion (two-ROM) movable arm, a one-ROM bucket rod and a two-ROM bucket. The excavator comprises a two-dimensional rotating arm mechanism, a one-dimensional rotating bucket rod mechanism and a two-dimensional rotating bucket mechanism. The two-dimensional rotating arm mechanism comprises a two-dimensional rotating arm, a first hydraulic cylinder and a second hydraulic cylinder; the one-dimensional rotating bucket rod comprises a one-dimensional rotating bucket rod and a third hydraulic cylinder; and the two-dimensional rotating bucket mechanism comprises a two-dimensional rotating bucket, a fourth hydraulic cylinder and a fifth hydraulic cylinder. Both the movably arm and the bucket of the novel excavator can realize independent spatial two-dimensional rotation, so that the whole excavator can realize spatial five-ROM motion; and the excavator is flexible in mechanism output loci, large in working space and high in work efficiency, and can play a good role in construction sites of severe environment and narrow space and emergency rescue sites in need of quick digging, obstacle clearing and flattening.

Description

technical field

[0001] The invention relates to the field of engineering excavators, in particular to a space excavator with a boom with two degrees of movement, an arm with degrees of movement and a bucket with two degrees of movement. Background technique

[0002] Hydraulic excavators are widely used in mechanized construction such as industry, transportation, energy, farmland renovation, water conservancy, civil construction, mining and modern military engineering due to their advantages of simple structure, light weight, and the ability to perform relatively complex actions. 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 cylinder, and then realizes the flipping of the bucket by driving a separate bucket hydraulic cylinder. However, due to its structural limitations, the actuators of this type of hydraulic excavator can only realize the tr...
