PROBLEM TO BE SOLVED: To perform the recovery of granules smoothly without causing the plugging of the granules as complying with various conditions.SOLUTION: This granule-discharging machine having the constitution of including a hopper for storing the granules, each of the rows of delivery parts for delivering the granules in the hopper and each of the rows of hoses for transferring the granules delivered at the delivery parts and discharging the granules transferred by the hoses on a field, and installing each of the rows of discharging ports for taking out the granules in the hopper, each of the rows of discharging shutters for opening and closing the discharging ports and recovering tubes for receiving, conveying and recovering the granules from each of the rows of discharging ports is provided by installing a residual amount sensor (207) for detecting the residual amount of the granules in the hopper and a controlling device for controlling the opening of the discharging shutters so that when the residual amount of the granules is large, the opening of the discharging shutters becomes small and when the residual amount of the granules is small, the opening of the discharging shutters becomes large based on the detection by the residual amount sensor (207).COPYRIGHT: (C)2012,JPO&INPIT【課題】 本発明は、種々の条件に対応して、粉粒体の詰まりを発生させずに円滑に粉粒体の回収を行えるようにすることを課題とする。【解決手段】 粉粒体を貯留するホッパと、該ホッパ内の粉粒体を繰り出す各条の繰出部と、該繰出部で繰り出された粉粒体を移送する各条のホースを備え、該ホースで移送された粉粒体を圃場に吐出する構成とし、ホッパ内の粉粒体を取り出すための各条の排出口と、該排出口を開閉する各条の排出シャッタと、各条の排出口からの粉粒体を受けて搬送し回収するための回収管を設けた粉粒体吐出機において、ホッパ内の粉粒体の残量を検出する残量センサ(207)を設け、残量センサ(207)の検出に基づき、粉粒体の残量が多いときには排出シャッタの開度が小さくなり、粉粒体の残量が少ないときには排出シャッタの開度が大きくなるよう、排出シャッタの開度を制御する制御装置を設けた。【選択図】図17
