块茎类中药材收获机械及核心装置研究进展OA

As the market demand for Chinese herbal medicines continues to expand,the demand for harvesting machinery for tuber-based Chinese medicinal crops is also growing.Currently,production in China is still largely dominated by manual and small-scale harvesters,with challenges such as low level of mechanization and high excavation resistance,which severely constrain the development of the Chinese herbal medicine industry.This study analyzes the research status of harvesting machinery of tuber crops(including medicinal plants)both domestically and internationally.It focuses on the development of mechanical dynamic models for harvesting tuber medicinal materials and on the performance optimization of key components,including excavation devices,separation and conveying systems,and collection devices.The analysis revealed several limitations,including a lack of systematic research on the coupled dynamics of soil,crop,and machinery;insufficient integration of agricultural machinery with agronomic practices;limited research on drag reduction and low-loss technologies;and inadequate integration of intelligent equipment.Based on these findings,this study proposed several recommendations,including prioritizing breakthroughs in the coupling mechanisms of soil,crops,and machinery,promoting the integration of agricultural machinery and agronomy,strengthening research on drag reduction and low-loss technologies,and promoting the integration of intelligent equipment.These efforts were expected to provide new insights and directions for the development of tuber crop harvesting machinery in China.
