PROBLEM TO BE SOLVED: To solve problems that poor attachment workability and complicated attachment/detachment work at a maintenance time are caused since a lubrication pump and a storage tank need to be attached on a rear face of a seedling base having many irregularities and that the connection failure or necessity of piping replacement is generated due to deformation or deterioration of a pipeline since the lubrication pump is manually operated and excess pressure is applied on a piping part due to properties of a lubricant or a state of the lubrication part or piping.SOLUTION: In a transplanter, a lubrication device 41 feeding a lubricant to a lubrication part 40 of a planting device 12 is attached. The lubrication device comprises: a grease cup 42 including a spring applying pressure to feed a lubricant stored inside the lubrication device 41 to the lubrication part 40 and an opening/closing valve 44 with an operation part arranged in a lubrication circuit. The grease cup 42 and opening/closing valve 44 are attached in a single bracket 46 which may be attached attachably/detachably to a planting device 12 and are unified, and the opening/closing valve 44 is attached directly below the grease cup 42.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】苗載台の凹凸の多い裏面に対して注油ポンプと貯留タンクを取付ける必要があるため、取付の作業性が悪くメンテナンス時の着脱作業も煩雑であるとともに、注油ポンプを手動操作するので、潤滑油の性状や潤滑部又は配管の状態等により配管部に過大な圧力が掛かるため、管路の変形や劣化等による接続不良又は配管の交換の必要性が生じる問題があった。【解決手段】植付装置12の潤滑部40に対し潤滑油を供給する給油装置41を取付けた移植機において、上記給油装置41の内部に収容した潤滑油を潤滑部40に供給するために与圧するスプリングを備えたグリースカップ42と、給油回路中に設けた操作部付きの開閉バルブ44とからなり、上記グリースカップ42と開閉バルブ44を植付装置12に着脱自在に取付けられる単一のブラケット46に取付けてユニット化するとともに、グリースカップ42の直下に開閉バルブ44を取付けてなる。【選択図】図3
