PROBLEM TO BE SOLVED: To provide a device for pressing corner bed soil of a seedling-raising box, preventing error of adjustment of height and depth while corresponding with seedling-raising boxes different in height and dealing with land leveling of corner soil different in raking depth, and facilitating adjustment to improve operability.SOLUTION: This device for pressing corner bed soil of a seedling-raising box is set on an upper position of a transfer stand 1 which horizontally transfers a seedling-raising box 2, with a front wall corner pressing mechanism 7 which has a front wall corner pressing body 15 pressing surplus corner soil which is produced after land-leveling the upper side of bed soil with a rotating land-leveling brush, and accumulated in the corner of the front wall 5 of the seedling-raising box 2, and a back wall corner pressing mechanism 30 which has a back wall corner pressing body 35 pressing surplus corner soil which is accumulated in the corner of the back wall 4 of the seedling-raising box 2. The front wall corner pressing mechanism 7 and the back wall corner pressing mechanism 30 are each attached to a right and left pair of corner land-leveling mechanism attaching plates 11. The corner land-leveling mechanism attaching plate 11 is attached through a height switching mechanism K to a height adjusting support plate 50 in a vertically movable manner. The height adjusting support plate 50 is attached to the frame 9 of the transfer stand 1 in a vertically movable manner with a height adjusting mechanism T.COPYRIGHT: (C)2008,JPO&INPIT【課題】隅部押圧体の高さ調節と深さ調節の混同、および、調節作業の煩雑化。【解決手段】育苗箱2を横送する移送台1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5の隅部に溜る余分な隅土を押圧する前壁隅部押圧体15を有する前壁隅部押圧機構7と、前記育苗箱2の後壁4の隅部に溜る余分な隅土を押圧する後壁隅部押圧体35を有する後壁隅部押圧機構30を設けたものにおいて、前記前壁隅部押圧機構7および後壁隅部押圧機構30は左右一対の隅部均平機構取付用板11に取付け、隅部均平機構取付用板11は、高さ切替機構Kを介して高さ調節用支持板50に上下動自在に取付け、該高さ調節用支持板50は、前記移送台1のフレーム9に対して高さ調節機構Tにより上下自在に取り付けた育苗箱の隅部床土押圧装置。【選択図】図1
