Abstract: In view of low efficiency of manual transplanting，longer time，not standard transplanting process，and large market demand，a lateral hanging transplanting machine was designed.The system was not only suitable for drought seedling transplanting，but also could be used as a transport device，and lifting transportation work platform and transplanting was combined to realize multi-usage.Its power source was battery power，non-polluting and no noise.Its automatic control system adopted Siemens PLC 200，encoder，motor speed and testing system of proximity switch control.It could accurate grab seedlings，and feed seedlings timely，effectively guarantee survival rate of seedlings and cultivation of consistency.
