青贮玉米籽粒破碎技术研究进展OA

Silage maize is regarded as a high-quality forage and served as a crucial material foundation for supporting the high-quality development of China's animal husbandry industry.To address the substantial demand for silage feed in the industry,accelerating the research and development as well as the industrialization of silage maize harvesters is considered essential,with kernel crushing technology and equipment identified as the core link affecting harvest quality.The research progress on silage maize kernel crushing technology both domestically and internationally was systematically reviewed in this paper.Starting from the working principles,the structural characteristics and application status of mainstream crushing devices,including differential roller type,toothed disc type,and combined type,were first summarized and compared.Furthermore,the related research methods and latest advancements were reviewed,focusing on the kernel crushing mechanism,key influencing factors and parameter optimization,and intelligent control technology.The analysis indicated that although certain progress had been made in this field in China,significant gaps compared to the international advanced level were identified in the in-depth understanding of the crushing mechanism,the materials and processes of key components,and intelligent closed-loop control.Based on this,the existing problems in current research were summarized,and future prospects were proposed from the directions of deepening mechanistic studies,breakthroughs in advanced manufacturing processes,and the construction of intelligent operational systems.This work was intended to provide a reference for the independent innovation and equipment upgrading of silage maize kernel crushing technology in China.
