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
