【0027】従来の張込量検出装置50としては、貯留装置43内において、満量と見なされる箇所に回転羽根を有し、負荷が大きくなったときにスイッチが動作して満量を検知したり、静電容量型でプローブの電気抵抗の検出により穀粒の有無を検出するものがあるが、いずれも穀粒の検出位置範囲は小さかった。 [0027] As a conventional Chokomi amount detecting device 50, the storage device 43 has a rotating blade at a location which is considered full amount, detects the full amount switch is operated when the load is increased or, it is intended to detect the presence or absence of grain by the detection of the electrical resistance of the probe in capacitive, one detection position scope of the grain was small.

【0028】上記課題を解決するため、前記手段を講じることにより、穀粒がまだ張り込まれていないときは、 [0028] To solve the above problems, by the taking measures, when the grain has not yet been Harikoma is
パイプ内の通気抵抗が小さいため、風速(風量を含む) Since flow resistance in the pipe is small, the wind speed (including air volume)
が速く、または圧力が小さいが、張込後、徐々に穀粒が貯留装置43に堆積し、前記パイプ51が埋まってくるとパイプ51に設けた吸気孔51aが塞がれ、通気抵抗が増大するため風速や風量は小さくなり、反対に圧力は増加してくる。 Although fast, or a small pressure, after Chokomi gradually grains are deposited in the storage device 43, when the pipe 51 will come buried suction holes 51a provided in the pipe 51 is blocked, increased airflow resistance wind speed and air volume is reduced to the pressure in the opposite comes increased. この風速または圧力をセンサ53により検出し、検出信号として張込量算出手段55へ出力し、 The wind speed or pressure is detected by the sensor 53, and outputs to Chokomi amount calculating means 55 as a detection signal,
予め設定している穀粒の張込量と前記風速または圧力の検出信号との関係から張込量算出手段55は張込量を算出する。 Chokomi amount calculating means 55 from the relationship between Chokomi amount and the detection signal of the wind speed or pressure of the grains that are preset to calculate the Chokomi amount.

【0029】この様にすると、穀粒に直接センサ53が接触しないため、衝撃等による機械的損傷が発生せず、 [0029] With this manner, since no direct contact sensor 53 within grains, mechanical damage due to impact or the like is not generated,
また、穀粒の付着による誤動作を生ずることがなく、安定した測定が行え、乾燥条件を設定するために重要な張込量を精度良く算出できる。 Also, without causing a malfunction due to grain adhesion, it can have stable measurement can accurately calculate the critical Chokomi amount to set the drying conditions.
