Abstract

This paper reviews the latest research advancements in the innovative design and application of intelligent technologies in threshing devices for main food crop combine harvesters. With the advancement of agricultural modernization, traditional threshing devices face challenges such as low threshing efficiency, poor adaptability, and low levels of intelligence. To address these issues, researchers have conducted in-depth analyses of threshing mechanisms and have proposed innovative designs for the threshing systems of crops such as wheat, maize, and soybeans. These designs include optimization of threshing components, improvements in drum design, and the introduction of differential variable diameter structures, significantly enhancing both threshing efficiency and crop adaptability. Furthermore, the application of intelligent technologies—including sensor monitoring of feed rate, breakage rate, impurity rate, and entrainment loss rate, as well as automated control and data analysis—has improved the precision and automation level of the threshing process in combine harvesters. These integrated technologies not only increase the operational efficiency of the threshing device but also reduce breakage and loss rates, providing critical support for the sustainable development of agricultural production. By reviewing innovative designs and the application of intelligent technologies in threshing devices for main food crop combine harvesters, this paper aims to offer insights and references for research and application in related fields, including threshing system structure design, operation parameter control, and on-line monitoring of threshing quality.
