PROBLEM TO BE SOLVED: To provide a corner part bed soil pressing device of a seedling raising box for pressing a surplus corner soil corner part which is accumulated on a corner part of a seedling raising box after making a top face of a bed soil filled in the seedling raising box even.SOLUTION: A corner part bed soil pressing device of a seedling raising box comprises: a rear wall corner part pressing part 12 having a pressing body 16 for pressing a surplus corner soil corner part S which is accumulated on a corner part of a front wall of a seedling raising box 2 after making a top face of the bed soil even by a rotary even brush, on an upper position of a transfer table for laterally transferring a seedling raising box 2. When a rear wall 4 of the seedling raising box 2 contacts the pressing body 16, the rear wall corner part pressing part 12 is configured so that the pressing body 16 is pressed by the seedling raising box 2 and moves forward, and the pressing body 16 drops by linear forward movement, and when dropping to predetermined depth where is capable of making the corner part S of the rear wall 4 of the seedling raising box 2 even, the pressing body 16 rotates upward to a center of a predetermined position on a rear upper part of the rear wall corner part pressing part 12, and gets over the rear wall 4.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2017,JPO&INPIT【課題】育苗箱に充填された床土の上面を均平した後にできる育苗箱の隅部に溜る余分な隅土隅部を押圧する育苗箱の隅部床土押圧装置を提供する。【解決手段】育苗箱2を横送する移送台の上方位置に、回転均平ブラシにより床土の上面を均平した後にできる育苗箱2の前壁の隅部に溜る余分な隅土隅部Sを押圧する押圧体16を有する後壁隅部押圧部12を設けたものにおいて、押圧体16に育苗箱2の後壁4が当接すると、後壁隅部押圧部12は押圧体16が育苗箱2に押されて前進すると共に押圧体16が直線状前進移動により下降し、育苗箱2の後壁4の隅部Sを均平しうる所定深さまで下降すると、後壁隅部押圧部12の後側上部の所定位置中心に押圧体16が上方回動して後壁4を乗り越えるように構成した育苗箱の隅部床土押圧装置。【選択図】図4
