Abstract: At present, there are some problems in picking process of Rosa roxburghii Tratt, such as low picking efficiency and high labor intensity．In order to improve overall operation efficiency of Rosa roxburghii Tratt picking, a Rosa roxburghii Tratt automatic picker integrating automatic picking, conveying and collecting was designed by using TRIZ theory．By using TRIZ identification tool function analysis, system function model of picker was constructed, contradiction and conflict were analyzed, and appropriate invention principle was selected to design optimal solution．Three-dimensional model of automatic picker of Rosa roxburghii Tratt was established by UG software, and finite element analysis of key components was carried out．Results showed that simulation analysis results met design requirements．The TRIZ theory was applied to design process of Rosa roxburghii Tratt automatic pickier, which verified feasibility of innovative design concept and provided an important reference for design and research of agricultural equipment．
