核桃振动采收技术及理论研究现状
The current status of mechanical and theoretical research on orchard fruit vibration harvesting machines
核桃是我国林果的重要一环，随着我国对坚果类需求的不断扩大，目前以人工采收为主的采收方式以无法满足日渐增长的需求，采用更高效的机械化采收代替人工是必然趋势。国内外学者对次都已经进行了较多研究。本文主要介绍了适用于我国不同核桃种植方式的振动采收机械，分析了在振动采收过程中的几个主要影响因素，并从林果振动采收机理、建立动力学模型、加速度传感器和基于高速摄像仪的果实运动实验三个方面阐述了国内外林果采收机械的理论研究现状，总结研究中存在的不足，并对我国未来核桃振动采收的研究方向进行了讨论。
Walnuts are an important part of China's forestry and fruit industry.With the continuous expansion of demand for nuts,the current harvesting method mainly based on manual harvesting cannot meet the growing demand.Therefore,adopting more efficient mechanized harvesting instead of manual harvesting is an inevitable trend.Scholars both domestically and internationally have conducted extensive research on this topic.This article mainly introduces the vibration harvesting machinery suitable for different walnut planting methods in China,analyzes several main influencing factors in the vibration harvesting process,and elaborates on the theoretical research status of forest fruit harvesting machinery at home and abroad from three aspects:the mechanism of forest fruit vibration harvesting,the establishment of dynamic models,and fruit movement experiments based on high-speed cameras.The shortcomings in the research are summarized,and the future research directions of walnut vibration harvesting in China are discussed.
