It is an annual herb, 1-3.5 meters high, up to 9 meters high, with an upright, round and angular stem, hard and covered with white and rough hair. The habitat of wild sunflowers is mainly grasslands and dry, open areas. They grow along roadsides, fields, desert edges and grasslands. When planting sunflowers, workers will use seeders to assist in sowing to improve sowing efficiency.

[0003] Existing sowing devices are usually designed to automatically and evenly sow sunflower seeds into the soil at a planting site to improve planting efficiency and seed utilization rate.
