Most of the tobacco seedling transplanters currently in use are semi-automatic transplanters that manually drop seedlings.In order to improve the efficiency of transplanting and reduce the labor intensity of farmers,a automatic seedling picking and feeding device for tobacco seedling transplanting machine is designed.SolidWorks software is used for modeling and overall design of the seedling picking and feeding device.The finite element software Workbench is used to calculate and simulate the strength of the frame,and conduct the vibration analysis on the process of picking and dropping seedlings.A driving control circuit is designed based on STM32 single chip microcomputer.This device adopts the operation method of interval seedling picking and unfolding seedling feeding,which can achieve automatic seedling picking and feeding.Through the assembly of physical prototypes and field experiments,the results show that the average success rate of seedling picking and feeding reaches 94.9% .This study can provide theoretical basis and technical reference for the research and development of automatic seedling picking and feeding devices.
