SEEDER AND SEEDING METHOD THEREFOR, AND AGRICULTURAL MACHINE WITH SEEDER
Document Type and Number:
WIPO Patent Application WO/2021/203506
Kind Code:
A1
Abstract:
Disclosed are a seeder (200) and a seeding method therefor, and an agricultural machine with the seeder (200). The seeder (200) comprises a screening element (10) and a seed-taking element (20). The screening element (10) has a waste discharge channel (11) and a seeding channel (12), the waste discharge channel (11) of the screening element (10) has a communication state and a closed state, and the waste discharge channel (11) of the screening element (10) is arranged to be switchable between the communication state and the closed state. The seed-taking element (20) is provided with a plurality of holding holes (21), and the seed-taking element (20) is configured to be capable of rotating relative to the screening element (10), such that the holding holes (21) of the seed-taking element (20) can be in communication with the waste discharge channel (11) or the seeding channel (12) of the screening element (10). The seeder can effectively remove waste seeds to ensure a seeding effect, can accurately take the seeds to reduce the reseeding rate, and can effectively ensure plant spacing to ensure seeding efficiency; and by allowing the seed-taking element to rotate relative to the screening element, the seeder can remove waste seeds and reduce the reseeding rate, such that the seeder is simple and reliable in structure, thereby reducing the failure rate of the seeder.
