PROBLEM TO BE SOLVED: To solve a problem that a bristle tip is deflected by contacting grains spilled from a groove of a delivery roll when the groove passes a brush, thereby a gap is generated between the brush and a surface of the delivery roll, and grains passing the brush increase.SOLUTION: A seeder 1 includes: a delivery roll 32 including plural grooves 33 holding grains and formed on a surface and a guide member 35 contacting a surface of the delivery roll 32 and guiding the grains in a state of being held in the grooves 33. By rotating the delivery roll 32 while holding grains in a predetermined amount in the grooves 33, the grains are fed to a lower side. The seeder 1 includes a partition brush 34 partitioning the grains held in the grooves 33 of the delivery roll 32. The partition brush 34 is positioned in a direct upper side of the delivery roll 32 and a bristle tip of the partition brush 34 is inclined to a rotation direction upstream side of the delivery roll 32.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】繰出ロールの溝がブラシを通過する際に、溝からあふれた粒体と接触して毛先がたわむことで、繰出ロールとの表面に隙間が生じてブラシを通過してしまう粒体が増える。【解決手段】播種装置1は、粒体を保持する溝33が表面に複数形成された繰出ロール32と、繰出ロール32の表面に当接し、溝33に保持された状態の粒体をガイドするガイド部材35と備え、溝33に所定量の粒体を保持しつつ、繰出ロール32を回転させることで、粒体を下方に供給する。播種装置1において、繰出ロール32の溝33に入る粒体を仕切る仕切りブラシ34を設けるとともに、仕切りブラシ34を繰出ロール32の直上方に位置させ、かつ、仕切りブラシ34の毛先を繰出ロール32の回転方向上流側に傾けた。【選択図】図2
