PROBLEM TO BE SOLVED: To provide a simpler structure of a driving mechanism for a scraper than a conventional art for scraping soil attached to a seedling planting body, in a seedling planting machine for planting seedlings in a field with the seedling planting body.SOLUTION: In the seedling planting machine, a seedling planting body case 63 is lifted by a rear link 68A and a front link 68B operated with the driving force from a planting transmission case 18, and a left seedling planting body 4aL and a right seedling planting body 4aR are disposed to be opened/closed in the lateral direction in the planting body case 63. The seedling planting machine also includes the scraper 70 for scraping soil by making slide contact with the inner/outer peripheral surfaces of the rising or falling left and right seedling planting bodies 4aL and 4aR. In the seedling planting machine, the scraper driving mechanism 50 for moving the scraper 70 to a position intersecting the rising or falling seedling planting bodies 4a is operated with the lifting motion of the rear link 68A and the front link 68B.COPYRIGHT: (C)2012,JPO&INPIT【課題】本発明は、苗植付体で苗を圃場に植え付ける苗植機において、苗植付体に付着する泥を掻き落とすスクレーパの駆動機構を従来の技術より簡単な構成で提供することが課題である。【解決手段】植付け伝動ケース18からの駆動力で作動する後リンク68Aと前リンク68Bで苗植付体ケース63を昇降し、該苗植付体ケース63に左右へ開閉すべく左側苗植付体4aLと右側苗植付体4aRを設け、昇降する左側苗植付体4aLと右側苗植付体4aRの内外周面に摺接して泥を掻き落とすスクレーパ70を設けた苗植機において、昇降する苗植付体4aと交差する位置にスクレーパ70を移動させるスクレーパ駆動機構50を前記前記後リンク68Aと前リンク68Bの昇降動作で作動する苗植機とする。【選択図】図2
