Abstract
The present invention discloses a method and an apparatus for pneumatically and accurately seeding vegetables and flowers. In the method, an air pump provides the pneumatic power of the whole working process, and a pneumatic motor drives a seeding head to rotate in the positive direction and the reverse direction. When the seeding head rotates to one side of a seed holding disk, the negative-pressure aspiration technique is utilized to adsorb fine particle seeds to a needle head of the seeding head. When the seeding head rotates to one side of a seeding support, the positive-pressure blowing technique is utilized to blow the fine particle seeds to small holes of the seeding support to be seeded in rows. The negative pressure of the seeding head is generated by that the airflow passes through a Venturi pipe. For the seeds with different grain sizes, and especially the small seeds, the present invention can realize the accurate seeding. The present invention solves the disadvantages of low speed, low precision, high seed-missing rate, etc. existing in the accurate seeding technique of plug seedling for the fine particle seeds.
