I. precision seeder head and seeder components including precision seeder head

摘要

According to some embodiments, the precision seed head includes a seed tube, and the inner ring is a size, which can accommodate seeds in any vertical position. The first seed box selectively blocks the seed tube, selectively unlocks to the seed tube when it is in the preset position, and vertically under the first seed box with an optical sensor when it is in the release position.There, optical sensors have been modified to detect seeds propagating from seed tubes.
