Abstract: In order to improve the harvesting conditions of siraitia grosvenorii and improve the picking efficiency, based on the growth characteristics and actual demand of siraitia grosvenori, a siraitia grosvenorii harvesting device was designed. The device model was established through UG and analyzed to optimize the design. Adams and Ansys conducted kinematics and finite element analysis, which verified the rationality of the designed device. Finally, the prototype was manufactured and tested. The results showed that the prototype of the harvesting device greatly improved the picking efficiency and met the requirements of use.
