PROBLEM TO BE SOLVED: To provide a paddy field working machine including a plurality of powder and grain supply parts each including a communicating pipe serving for communication between a ditching machine and a conveying pipe from a delivery mechanism, in a state of reducing the required types of communicating pipes and facilitating the appropriate assembly of the communicating pipes.SOLUTION: A plurality of communicating pipes 24 are formed to include bent parts 83 between both ends and to have the identical form of the bent parts. Connection specifications of connection parts 81, 82 for connecting the plurality of communicating pipes 24 to the conveying pipe side and connection parts 81, 82 for connecting the plurality of communicating pipes 24 to the ditching machine side are set to be identical so that the plurality of communicating pipes 24 are respectively applicable to communication with either a plurality of conveying pipes 27 and a plurality of ditching machines 19. The plurality of communicating pipes 24 are provided with indicators 91-94 that indicate mounting attitudes in the case of being applied to respective communication with the plurality of conveying pipes 27 and the plurality of ditching machines 19.COPYRIGHT: (C)2013,JPO&INPIT【課題】繰出し機構からの搬送管と作溝器を連通させる連通パイプを備えた粉粒体供給部の複数を備える水田作業機を、連通パイプの必要種類を少なく済ませる状態で、かつ連通パイプの適切な組み付けを行い易い状態で得る。【解決手段】複数本の連通パイプ24を、両端部間に屈曲部83を備えるように、かつ同一の屈曲部形態を備えるように形成してある。複数本の連通パイプ24それぞれを複数の搬送管27及び複数の作溝器19のいずれの連通にも適用可能なように、複数本の連通パイプ24の搬送管側に連結するための連結部81,82及び作溝器側に連結するための連結部81,82の連結用仕様を同一に設定してある。複数本の連通パイプ24に、複数の搬送管27及び複数の作溝器19それぞれの連通に適用する場合の取付け姿勢を表示する指標91~94を設けてある。【選択図】図4
