APPARATUS FOR TAKING OUT SEED

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for taking out a seed, with which only one grain is surely adsorbed on the top face of a seed taking out shaft 18 from seeds in a hopper 17 and taken out in the upward movement of the seed taking out shaft 18 in the hopper 17 in a vacuum adsorption type sowing apparatus for sowing seeds in seedling raising pots on a sowing tray. SOLUTION: The apparatus for taking out the seed has constitution that the seed taking out shaft 18 is equipped with a sleeve 19 enclosing the outer periphery of the seed taking out shaft and the sleeve 19 is upward moved up to proper height together with the seed taking out shaft 18 and then downward moved relatively to the seed taking out shaft 18. While the sleeve 19 is upward moved together with the seed taking out shaft 18, the upper end part of the sleeve 19 is projected upward more than the upper end face of the seed taking out shaft 18. The upper end face of the sleeve 19 is formed in a downward narrowing tapered face 49. COPYRIGHT: (C)2004,JPO&NCIPI
