COMBINE

摘要

The objective of the present invention is to provide a combine that can eliminate the effect of disturbance from grain quantity detection values, even during a period of contact in which grain contacts a sensor. The impact force detected by a discharging opening sensor is compared with a pre-set threshold (a). On the basis of the comparison results, it is determined whether or not the impact force is included in the subject of calculation. For example, if the impact force is less than the threshold (a), the impact force is removed from being a subject of calculation. As a result, particularly when a small quantity of grain is being conveyed (for example, in the case of harvesting work being performed at a low speed or the case of a hand-threshing mode), it is possible to improve the calculation precision of the amount of grain. If the amount of grain conveyed is small, the effect of disturbance on the calculated amount of grain is larger than when the amount of grain conveyed is large.
