Title:
DISPLAY SYSTEM FOR HYDRAULIC EXCAVATOR
Document Type and Number:
WIPO Patent Application WO/2023/188319
Kind Code:
A1
Abstract:
Provided is a display system for a hydraulic excavator, which can provide an angle formed by a bucket and a target construction surface to an operator in an easy-to-understand manner, even if the target construction surface is covered with earth and sand, and the bucket and the target construction surface are apart from each other during excavation work. Therefore, a controller 20 calculates a ground angle θb of a bottom surface 11H of a bucket 11c and a ground angle θd of a target construction surface 55 on the basis of the detection signals of attitude sensors 12a, 12b, 12c, 12d and measurement information on GNSS receivers 14a, 14b, 21, and a monitor 19 displays a linear image 61a representing the ground angle θd of the target construction surface 55 superimposed on a bucket side image 60 on the basis of the ground angle θb of the bottom surface 11H of the bucket 11c and the ground angle θd of the target construction surface 55.
