Problem to be solved: to detect an illegal flow into a measuring container in a combine for measuring grains stored in a measuring container formed in a grain tank.The combine comprises a grain transporting apparatus for transporting the grains obtained in the decontamination apparatus to the grain tank 7 and a flow rate measuring means GV for measuring the flow rate of the supplied grain.The flow rate measuring means GV is provided inside the granule tank, and the flow rate is measured on the basis of the time in which a constant amount of the granule is stored in the measuring container 40 for receiving and storing a part of the grain which is fed into the grain tank 7 from the receiving port 41.Based on the amount of change in the flow rate, an illegal inflow detecting portion 68 is provided which detects the inflow of the granules stored outside the measuring container 40 in the cereal tank 7 into the measuring container 40 from the receiving port 41.Diagram【課題】穀粒タンク内に形成された測定容器内に貯留させた穀粒を測定するコンバインにおいて、測定容器内への不正な流れ込みを検知できること。【解決手段】コンバインは、脱穀装置で得られた穀粒を搬送して穀粒タンク７に投入する穀粒搬送装置と、投入される穀粒の流量を測定する流量測定手段ＧＶとを備える。流量測定手段ＧＶは穀粒タンクの内部に設けられ、穀粒タンク７に投入される穀粒の一部を受け入れ口４１から受け入れて貯留する測定容器４０に一定量の穀粒が貯留される時間に基づいて流量を測定する。流量の経時的変化量に基づいて、穀粒タンク７における測定容器４０の外部に貯留されている穀粒が受け入れ口４１から測定容器４０に流れ込む不正流入を検知する不正流入検知部６８が備えられている。【選択図】図５
