Description

Technical Field

[0001] The invention relates to a sowing mechanism, in particular to a high-speed sowing hole seeder suitable for large seeds such as cotton, corn or sunflower. Background Art

[0002] Existing hole-seeding mechanisms, especially air-suction drum hole-seeders, take seeds through a drum assembly, which consists of a hollow shaft, an air-suction seed disc, a seed separator and a duckbill hole-forming device. Seed suction holes are evenly distributed on the surface of the seed disc, and seeds are adsorbed by negative pressure. When the seed disc rotates with the drum, the seed suction holes adsorb seeds under the action of negative pressure. After reaching the seed unloading area, the air-cutting device cuts off the negative pressure, and the seeds are guided to the duckbill for sowing through the seed separator.

[0003] When the mechanism is operating at high speed, the linear speed of the seed suction disc is too high, resulting in insufficient seed filling time and poor seed filling effect, which can easily cause missed seeds and reseeding problems, seriously affecting the sowing quality. In order to ensure the sowing quality, the operating efficiency must be sacrificed.

[0004] Therefore, a high-speed seed drill that can take into account multiple operations has emerged. Summary of the Invention
