PROBLEM TO BE SOLVED: To accurately detect a full state with respect to grain varieties different in repose angle in a set amount detection sensor of a grain storage tank.SOLUTION: Grain is transported from grain transportation means (1) to a grain storage tank (2) and is stored, and the grain taken out by taking-out means of the grain storage tank (2) is supplied to a grain processing machine (3) of the next process. A plurality of set amount detection sensors (SE1, ...) are disposed on the side wall of the grain storage tank (2) while being vertically shifted from each other, and a plurality of pieces of grain variety property selection means (SW3, ...) are provided on a control panel for designating the variety and property of grain. A controller 33 is provided, which selects the set amount detection sensor in charge of detection among the plurality of set amount detection sensors (SE1, ...) according to the selection of the grain variety property selection means (SW3, ...), stops driving of the grain transportation means (1) when the selected set amount detection sensor (SE1) detects existence of grain, and resumes the driving of the grain transportation means (1) when the set amount detection sensor (SE1) detects nonexistence of grain.COPYRIGHT: (C)2015,JPO&INPIT【課題】穀物収容タンクの設定量検出センサにおいて、安息角の異なる穀物品種に対して正確な満量検出をする。【解決手段】穀物搬送手段(1)から穀物収容タンク(2)に穀物を搬送収容し、穀物収容タンク(2)の繰出手段で繰り出した穀物を次工程の穀物調製機(3)に供給するようにする。該穀物収容タンク(2)の側壁には複数の設定量検出センサ(SE1,…)を上下方向にずらせて配設し、操作盤には穀物の品種や性状を指定する穀物品種性状選択手段(SW3,…)を複数設ける。該穀物品種性状選択手段(SW3,…)の選択に応じて複数の設定量検出センサ(SE1,…)のなかから検出担当の設定量検出センサを選択し、選択された当該設定量検出センサ(SE1)が穀物有り検出をすると前記穀物搬送手段(1)の駆動を停止し、当該設定量検出センサ(SE1)が穀物無し検出をすると前記穀物搬送手段(1)の駆動を再開するコントローラ33を設ける。【選択図】図2
