Abstract：Inviewof the problems suchasinsufficientexcavation depth of existingtraditional Chinese medicine harvesters tomeettherequirementsof Astragalus membranaceus harvesting，highoperationalresistanceandpoorseparationeffectof broken soil，a vibration excavation type Astragalus membranaceus harvester is designed.The prototype mainly consists of avibration excavation device，a stem soil separation device，and a conveying and screening device.According tothe motionanalysisofthevibration excavatorshovel，thevibration frequencyandamplitudeof theexcavatorshovel，the size ofthesupport frame，and the parametersof theeccentric whelwere determined.Byanalyzing thestressofthe stem soil mixture，the vibration frequencyandefective length of the screen surface of the vibrating screenwas designed.Afiled experimentswasconductedtoverifytheoperational performance of harvesting prototypes.Theresultsshowedthat the average excavation depth of the harvested prototype was 409mm ，the average damage rate of Astragalus membranaceus root and stem was 2.51% ，the average excavation rate was 97.5% ，and the maximum diameter size of the broken soil block was 17mm .The prototype runs smoothly during the experimental process，and can achieve the excavation of longer rooted Chinese medicinal materialssuch as Astragalus membranaceus，as wellastheseparation and harvesting of stemsoil mixtures. The study can provide some reference for the design of Chinese medicine harvester.
