PROBLEM TO BE SOLVED: To get a rice transplanter, the ditching machine of which includes an air bleeding trunk leading to a fertilizer supply path for supplying a fertilizer by carrying wind while being easy to avoid the powder of the fertilizer, leaked from the air bleeding trunk, falling and riding on a planter frame or mud, tipped up by a seeding planting mechanism, getting on the exhaust port of the air bleeding trunk.SOLUTION: The rice transplanter includes the planter body frame 30, which includes a plurality of longitudinal planter drive cases 29, which stand transversely, and a transverse coupling member 28, which couples the front sides of the plurality of longitudinal planter drive cases 29. The exhaust port 64a of the air bleed trunk communicating with the fertilizer supply path 23 is arranged so that it may be positioned on a level lower than the top 28a of the transverse coupling member 28 and that it may be piled, in the longitudinal direction of machine body, on the fertilizer supply path 23, before the fertilizer supply path 23.COPYRIGHT: (C)2013,JPO&INPIT【課題】作溝器に肥料を搬送風によって供給する肥料供給路に連通するエア抜き風路を備える田植機を、エア抜き風路から漏れ出た肥料粉末が植付け機体フレームに落下して乗ることや、苗植付け機構によって跳ね上げられた泥土がエア抜き風路の排気口に掛かることを回避し易い状態で得る。【解決手段】機体横方向に並ぶ複数の機体前後向きの植付け駆動ケース29及び複数の植付け駆動ケース29の前端側を連結する機体横向きの連結部材28を備えて構成される植付け機体フレーム30を備えている。肥料供給路23に連通するエア抜き風路の排気口64aを、連結部材28の上端28aより低い配置高さに位置するように、かつ肥料供給路23の前方に肥料供給路23と機体前後方向に重なって位置するように配置してある。【選択図】図3
