PROBLEM TO BE SOLVED: To provide a granule distributer capable of properly diffusing and discharging granule on a worked area of a farm field, where a predetermined work was applied.SOLUTION: The distributer is composed by providing a rotary dispersing means 27 dispersing with blow the granules drawn out from a drawing means and guiding means 59 and 60 guiding the granules dispersed with the rotary dispersing means 27 to diffuse and dischage on the farm field, and is composed by providing a worked area detecting means detecting a worked area Z of the farm field on which area a predetermined work is already applied and a dispersing area changing means SH changing the dispersing area of the farm field on which area the granule is dispersed with the rotary dispersing means 27 and guided with the guiding means 59 and 60 based on the detection information of the worked area detecting means so as to correspond to the worked area Z.COPYRIGHT: (C)2012,JPO&INPIT【課題】圃場において所定の作業が行われた既作業領域に対して適切に粉粒体を拡散放出させることが可能となる粉粒体散布装置を提供する。【解決手段】繰出し手段から繰り出される粉粒体を打撃により飛散させる回転式飛散手段27と、その回転式飛散手段27により飛散される粉粒体を圃場に拡散放出すべく案内する案内手段59,60とを備えて構成され、圃場において所定の作業が既に行われた既作業領域Zを検出する既作業領域検出手段と、既作業領域検出手段の検出情報に基づいて、回転式飛散手段27により飛散され且つ案内手段59,60により案内される粉粒体の圃場に対する散布領域を既作業領域Zに対応させるように変更する散布領域変更手段SHとを備えて構成されている。【選択図】図12
