PROBLEM TO BE SOLVED: To provide a divided type feed roll structure of a seeding machine for a nursery box in which a feed roll is constituted by combining multiple unit resin plates and integrating them.SOLUTION: A feed roll in a seeding machine for a nursery box is characterized in that a certain amount of seeds is fitted in a recess and fed, is conveyed while rotating, and is dropped in a nursery position of a nursery container. The feed roll is constituted of the recess with a certain amount of seeds fitted therein as a feeding concave groove part of a groove shape in an outer circumference of the roll of a cylindrical tube. The feed roll of the cylindrical tube is constituted by combining multiple doughnut-shaped unit resin plates and then integrally fixing them. In an outer circumference every one piece of the doughnut-shaped unit resin plates, the groove for constituting the unit feeding concave groove part is drilled as a portion of the feeding concave groove part.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2017,JPO&INPIT【課題】繰出しロールを複数枚の単位樹脂板を重合して一体化することにより構成した育苗箱用播種機の分割式繰出しロール構造を提供する。【解決手段】育苗箱用播種機において、一定量の種子を凹部に嵌入させて繰出し、回転しながら搬送し、育苗容器の育苗位置に落下させる繰出しロールにおいて、該繰出しロールを円筒筒条のロールの外周に、種子の一定量を嵌入させる凹部を条溝形状の繰出凹状溝部として構成し、該円筒筒条の繰出しロールを、ドーナツ状の単位樹脂板を、複数枚重合した後に一体的に固定して構成し、該ドーナツ状の単位樹脂板の1枚毎の外周に、前記繰出凹状溝部の一部としての単位繰出凹状溝部を構成する溝を穿設させた。【選択図】図6
