Current Status and Development Strategies of the Research on Half-Feed Peanut Combine Harvester

Peanut (Arachis hypogaea L.) is an important oil and economic crop, widely cultivated across various regions, with China leading global peanut production. The mechanization of peanut harvesting plays a crucial role in advancing the entire peanut industry. Half-feed peanut combine harvesters, characterized by high operational integration, can complete the harvesting of mature peanuts in a single pass and are widely used in major production areas such as Henan and Shandong in China. This paper summarizes the development history of half-feed peanut combine harvesters in the context of current peanut-planting and harvesting models, outlining their main types and operational characteristics. It also reviews the information technologies applied to these machines, including autonomous driving, harvesting quality detection, and adaptive control of operational parameters, summarizing their main types and working principles. Based on the current demand for intelligent and automated operations, the paper analyzes the main issues and development strategies for half-feed peanut combine harvesters, providing a theoretical basis for their development and the advancement of the peanut industry.
