Seeding delivery roll of seedling seedling machine

摘要

The purpose of the present invention is to provide a seed feeding roll for a seeding machine for seedling culture, capable of achieving improved accuracy of seeding and uniformly dispersing a small amount of seeds. In the seed feeding roll, linear grooves of feeding recesses (3) formed in a seed feeding roll (K) are formed in a helical shape extending around the outer peripheral surface of the seed feeding roll (K). The helical linear grooves are formed from one lateral end portion of the seed feeding roll (K) to the center of the lateral width of the seed feeding roll (K), and opposite-site linear grooves with a reverse helical shape symmetrical with the aforementioned grooves are formed from the other lateral end portion to the center. Thus, the multiple linear grooves of the feeding recess (3) on the outer peripheral surface of the seed feeding roll (K) are arranged in the form of V-shaped grooves.
