PROBLEM TO BE SOLVED: To enhance the operational efficiency of a discharge operation by a grain discharging apparatus.SOLUTION: When a switched state detection means (23) detects that a discharge opening (12) has been switched to a first state in which it is open downward, a transmission state switching means (43) is immediately switched to a transmission connection state according to a switching operation by a discharge command means (38) to the transmission connection state. When the switched state detection means (23) detects that the discharge opening (12) has been switched to a second state in which it is not open downward, the transmission state switching means (43) is maintained in a transmission shutting state if the switching operation by the discharge command means (38) to the transmission connection state is canceled before a set period of time elapses. If the switching operation by the discharge command means (38) to the transmission connection state is continued beyond the set period of time, the transmission state switching means (43) is switched to the transmission connection state.COPYRIGHT: (C)2013,JPO&INPIT【課題】穀粒排出装置による排出作業の作業能率を高める。【解決手段】切換状態検出手段(23)によって排出口(12)が下向きに開放されたの第1状態に切り換えられていることが検出された場合には、排出指令手段(38)による伝動接続状態への切換操作に基づいて伝動状態切換手段(43)を直ちに伝動接続状態に切り換え、切換状態検出手段(23)によって排出口(12)が下向きには開放されない第2状態に切り換えられていることが検出された場合に、排出指令手段(38)による伝動接続状態への切換操作が設定時間経過する前に解除されたときには、伝動状態切換手段(43)を伝動遮断状態に維持し、排出指令手段(38)による伝動接続状態への切換操作が上記設定時間を超えて継続したときには、伝動状態切換手段(43)を伝動接続状態に切り換える。【選択図】図10
