PROBLEM TO BE SOLVED: To provide a planting machine which can form opening portions in a field and efficiently accurately plant seed bulbs in the opening portions.SOLUTION: The planting machine 1 has a travel portion 14, a planting portion 17, and a driving portion 13 for generating a driving force to the travel portion 14 and the planting portion 17, and the planting portion 17 has a holding opening means 20 for holding seed bulbs G and forming opening portions in a field, and a pushing out device 4 for pressing seed bulbs G to the opening portions formed with the holding opening means 20 to plant the seed bulbs G in the field. The pushing out device 4 has a planting press portion 7 for pressing the seed bulbs G to the field at prescribed timing the planting press portion 7 comprises a plurality of planting pushing out members 70 each comprising a planting rod 72 and a guide pipe 71 into which the planting rod 72 is inserted. An engaging member 9 is arranged on the guide pipe 71 and the planting frame 18, and temporarily controls the lift of the planting rod 72 to first lift the guide pipe 71, when the planting pushing out member 70 is lifted after the planting is finished.COPYRIGHT: (C)2011,JPO&INPIT【課題】圃場に開孔部を形成して、該開孔部に種球を効率よく的確に植付けることができる植付機を提供する。【解決手段】走行部14と、植付部17と、植付部17及び走行部14への駆動力を発生させる駆動部13とを備える植付機1であって、植付部17は、種球Gを保持するとともに圃場に開孔部を形成する保持開孔手段20と、保持開孔手段20が形成した開孔部に、種球Gを押付けて圃場に植付ける押出装置4とを備え、押出装置4は、所定のタイミングで種球Gを圃場に押付ける植付押出部7とを備え、植付押出部7は、植付ロッド72と、植付ロッド72を内挿するガイドパイプ71とにより成る複数の植付押出体70により構成され、ガイドパイプ71と植付フレーム18には係合部9が配設され、植付終了後に植付押出体70が上昇するときに、係合部9により植付ロッド72の上昇が一時的に規制され、ガイドパイプ71が先に上昇される。【選択図】図13
