PROBLEM TO BE SOLVED: To provide a seedling feed roll of a seeder for raising seedling which improves a degree of accuracy of seedling and enables planting of a uniform small amount.SOLUTION: A strip groove of a feeding recessed part 3 bored in a seedling feed roll K is bored in a screw shape to wind around an outer periphery of the seedling feed roll K. The strip groove of a screw strip is bored from one of right and left end parts of the seedling feed roll K to a central position of a lateral width of the seedling feed roll K, and a strip groove, configured to be symmetric and to form an opposite screw shape, on an opposite side is bored from the other one of the right and left end parts to the central position so that the strip groove of one feeding recessed part 3 of the seedling feed roll K is arranged as a V-shaped groove.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2018,JPO&INPIT【課題】播種精度の向上を図り、少量均一散播が可能な育苗用播種機の播種繰出ロールを提供する。【解決手段】播種繰出ロールKに穿設する繰出凹部3の条溝を、播種繰出ロールKの外周を巻くようにスクリュー状に穿設し、該スクリュー条の条溝は、播種繰出ロールKの左右の一端部から、該播種繰出ロールKの左右の幅の中心位置まで穿設し、左右の他端部からも、これと対称的に逆のスクリュー状に構成した反対側の条溝を中心位置まで穿設して、播種繰出ロールKの1本の繰出凹部3の条溝をV字状の溝として配列した。【選択図】図8
