摘要：

In order to solve the problems of easy seed shedding and poor seed population mobility during sowing, a precision seed metering tray for edible sunflowers with seed guide strips was designed in this paper. This article aims to adjust the adsorption posture of sunflower seeds by designing three types of structures: triangular seed guide strip, rectangular seed guide strip, and diamond seed guide strip. Seed population motion simulation and seeding performance experiments were conducted on the seeder. The experimental results show that adding a triangular seed guide strip to the seeding tray has the best disturbance effect on the seed population, with the highest proportion of seeds in the first adsorption stance seed (the seed centroid was adsorbed) and the highest qualification index. The working parameters for the best seed metering performance were obtained: the rotating speed of the seed metering disc was 8.41 r/min, and the vacuum degree was 3.5 kPa.
