Abstract

The invention discloses a hydraulic excavator intelligent ground levelling device and a control method thereof. A controller of the intelligent ground levelling device is electrically connected with an instrument and a ground levelling module; and a moving arm cylinder position sensor, a bucket arm cylinder position sensor, a bucket cylinder position sensor, a moving arm ascending electromagneticvalve, a moving arm descending electromagnetic valve, a bucket rod external swinging electromagnetic valve, a bucket rod adduction electromagnetic valve, a bucket external swinging electromagnetic valve, a bucket adduction electromagnetic valve and a ground levelling operating switch are electrically connected with the ground levelling module separately. According to the hydraulic excavator intelligent ground levelling device, through modularized configuration of the intelligent ground levelling function, self adjustment of the bucket angle is realized, setting of the external swinging angle is realized and the self learning of the ground levelling function is realized; and through the ground levelling switch, automatic ground levelling is realized, and both automatic adduction ground levelling and automatic external swinging ground levelling are realized.

Description

technical field [0001] The invention relates to the field of excavators, in particular to an intelligent leveling device for a hydraulic excavator and a control method thereof. Background technique [0002] In recent years, with the acceleration of urbanization in our country, the country has increased the amount of engineering construction in the fields of transportation, construction, and water conservancy projects. The market demand for construction machinery all over the country has increased sharply, especially the demand for hydraulic excavators continues to grow, and the requirements for intelligent control of hydraulic excavators are getting higher and higher. [0003] At present, hydraulic excavators are used more and more for leveling functions in the working process, which requires high operating skills of the driver, and generally requires long-term work training and experience accumulation. The work intensity is relatively high, and the two-way leveling effect ...
