Claims (1)

[Scope of claims for utility model registration] (1) A rotating perforated plate 4 is placed at the bottom of the seed tank,
In a feeding device that holds seeds in seed holes 4a provided in the rotary perforated plate 4 and drops a certain number of seeds at a seed drop opening 2h, the seed holes 4 inside and outside of the rotary perforated plate 4 are used.
Along the line Q connecting the center lines of a and 4a, on the parallel line M at the position opposite to the rotational direction of the rotary perforation plate 4 by the radius R of the seed hole 4a, in front of the seed droplet of the seed droplet 2h. A perforated seeding device characterized by having a 2hF wall configured linearly. (2) The rear wall 2hR of the seed droplet 2h is placed on a parallel line N drawn in the direction of rotation of the rotary perforated plate 4 with respect to the parallel line M described in claim 1 of the utility model registration claim. A perforated seeding device characterized by a linear configuration. (3) A perforated-type seeding device characterized in that the knot 6 which comes into contact with and urges the upper part of the seed hole 4a as described in claim 1 of the Utility Model Registration is constituted by a spring plate having a downward convex surface.
