Description

Technical Field

[0002] In the context of the rapid development of modern agricultural technology, the performance and applicability of seed drills, as key equipment for improving agricultural production efficiency, are directly related to the quality and economic benefits of crop planting. Currently, seed drills on the market are mainly divided into two categories: one is large-scale high-end equipment represented by traction-type air-suction seed drills, and the other is hand-push seed drills for small farmers. Although each has its own advantages, both have limitations that cannot be ignored.

[0003] Trailed air seeders have shown significant advantages in large farms and commercial planting due to their large-scale operation capabilities, high human resource utilization, and excellent seed precision placement technology. However, the high purchase cost, high energy consumption, and complex maintenance requirements make this type of equipment too expensive and unaffordable for farmers with limited funds and small scale.

[0004] In contrast, the hand-push seeder, with its small size and easy operation, is better adapted to the cultivation needs of small farmlands and reduces the labor intensity of farmers in the absence of mechanization. However, this type of machinery fails to integrate furrowing, sowing and covering soil, and is still highly dependent on human drive, resulting in limited operating efficiency, especially when planting on a large scale, farmers need to invest a lot of physical labor. In addition, its unique mechanical structure makes maintenance relatively difficult, further increasing the cost and difficulty of use. Utility Model Content
