PROBLEM TO BE SOLVED: To provide a rice planting machine in which securement of the yield, reduction of seedling cost and labor reduction of seedling/seedling carrying work can be achieved, even if a hill space is not changed with a hill space transmission in seedling planting work (in the viewpoint different from sparse planting).SOLUTION: A rice planting machine 1 of the present invention includes a seedling load platform 29 having a seedling longitudinal feeding belt 217 for carrying a seedling mat 207, and planting claws 30 for planting seedlings 205 in the fields. The rice planting machine is configured such that the seedling mat 207 on the seedling load platform 29 is carried out to the seedling picking side with the seedling longitudinal feeding belt 217, and the seedling load platform 29 is reciprocated in the lateral direction and one seedling 205 is raked from the seedling mat 207 on the seedling load platform 29 with the planting claws 30. The rice planting machine includes U-shaped extrusion pieces 234 for extruding the seedlings held with the planting claws 30, and push rods 235 for making the extrusion pieces 234 slide along the planting claws 30. The tip sides of the planting claws 30 have a width narrower than the base end side, the upper end outsides of the extrusion pieces 234 are formed in a chamfering shape, and the upper end sides of the extrusion pieces 234 are made to slidably approach to the back sides of the narrow tip sides of the planting claws 30.COPYRIGHT: (C)2015,JPO&INPIT【課題】苗植え作業において、株間変速装置で株間を変更しなくても(疎植とは別の視点で)、収量の確保、育苗コストの低減並びに育苗・苗運び作業の労力軽減を図る。【解決手段】本願発明の田植機1は、苗マット207搬送用の苗縦送りベルト217を有する苗載台29と、圃場に苗205を植付ける植付爪30とを備える。苗縦送りベルト217で苗載台29上の苗マット207を苗取出し側に搬送し、苗載台29を左右方向に往復移動させて、植付爪30で苗載台29上の苗マット207から1株分の苗205を掻き取るように構成する。植付爪30で挟持した苗を押し出すU字状の押出片234と、押出片234を植付爪30に沿って摺動させるプッシュロッド235とを備え、植付爪30の先端側を基端側よりも幅狭に構成し、押出片234の上端部外側を面取り形状に形成し、押出片234の上端側を植付爪30の幅狭な先端側の裏面に摺動自在に近接させる。【選択図】図3
