Abstract

With the continuous advancement of agricultural mechanization technology, intelligent header technology has become a crucial component in enhancing the efficiency and quality of grain combine harvesters. This paper provides a comprehensive analysis of the current state of intelligent header technology, focusing on the structure and working principles of headers, as well as contour-following and height control technologies. By integrating advanced sensor technology, control algorithms, and mechanical structure optimization, intelligent headers achieve precise control over height and posture, significantly reducing crop losses and improving harvesting efficiency and quality. Despite significant progress, limitations still exist in response speed, real-time performance, height measurement, and control algorithms. Looking ahead, research will focus on enhancing control system performance, optimizing component and system design, and incorporating new technologies to adapt to diverse crops and complex terrains. This paper also critically reviews the current shortcomings of intelligent header research and projects future research trends, providing theoretical and practical references for header structure optimization, loss reduction, and the enhancement of intelligent capabilities. The goal is to promote the continuous advancement and innovation of header technology in combine harvesters.
