Excavator high man-machine work efficiency control device

The invention belongs to an engineering machinery man-machine interaction control technology, and in particular, relates to an excavator high man-machine work efficiency control device based on speed control. A left cross control handle controls movement of a bucket rod in a traditional excavator control mode; and a right cross control handle controls movement of a bucket and a movable arm. In actual excavation, the left-right hand compound control for three parts is frequently needed. As the excavator bucket, the bucket rod and the movable arm all move in a vertical plane, from design of the man-machine effect, the control mode is not corresponding to the self movement process of excavator parts, the excavator operation mastering time is long, the working difficulty is great, and the final use efficiency and the operability of an excavator are directly influenced. The excavator high man-machine work efficiency control device improves the problem that a traditional excavator control device is not accordant wi
