Abstract: There are some problems in artificial sowing of American ginseng, such as high labor intensity and low efficiency, lack of mechanized sowing technology and equipment. A doublerow seeder for American ginseng was designed by using the planting agronomy of curved ridges in Shandong Province and the narrow and dense planting mode of American ginseng. Through the seed characteristics of American ginseng, the spoon hole size was designed.With the narrow planting mode of American ginseng, the plug pushing hole opening program was determined. By using the multilink mechanism, the inclination angle of the spoon and the movement of the hole opener are controlled, and the linkage of seed picking, hole opening and seed dropping process was completed. This machine is mainly composed of a seed collection mechanism, a hole opener, a seed pushing mechanism, etc, which can complete the seed collection, seed throwing and sowing operations at one time. It realizes the double row sowing effect of American ginseng seeds, and improves the efficiency and quality of American ginseng sowing. Field experiments show that: the qualified rate of sowing was 92.76%, the missing rate was 4.58%, and the replay rate was 2.66%, which met the requirements of American ginseng sowing and various technical indicators.

Key words: American ginseng, seeding, blank takeout mechanism, hole opening
