Abstract：Aiming attheproblemsof high labor intensityandlowoperation eficiencyof theexistingAmericanginseng seeders in China，anew self-propelled American ginseng seeder has been designed.Basedon theirregularshape and poor fluidity of American ginseng seeds，a cuppedwhel type seedmetering device was selected.Through single-factor experiments，theseed metering wheel wasoptimized，andfinallyaseed metering wheel withthree horizontallyplaced holes and a seed guiding groove inclination of 30∘ was chosen. For the large seeding density of Siberian ginseng on the ridge，a top-push planting device was designed.By developing an auxiliary optimization software，the structural parameters L0 ， L1 L2 L3 ， L5 ， L6 of the crank-rocker mechanism and the cam pushTrod mechanism，as wellas the installation angles φ0 ， δ ， η2 were determined to be 144mm ， 46mm ， 134mm ， 144mm ， 103mm ， 93mm ， 60∘ ， 58∘ ，and 90∘ respectively.Field trials have shown that the machine has a dropout rate of 10.16% ，a re-sowing rate of 4.52% ，and a qualified rate of 85.32% ：
