Due to the lack of integrated mechanized farm equipment for spinach cultivation in the current market, this paper studies a multifunctional spinach cultivation machine, which applies modular and multifunctional design, through the design of four functional structures, so that it can adapt to different soil conditions and crop planting needs. The structural reliability and use stability of the agricultural machine are verified through the design calculation of torque, the role of institutional bearing force and finite element static load analysis. After a large number of experiments and practical applications, it is verified that this agricultural machinery has certain practical applicability, thus alleviating the market gap of spinach planting integrated agricultural machinery and equipment to a certain extent.
