PROBLEM TO BE SOLVED: To provide a combine harvester improving a case of an excessive opening of a chaff sieve caused by objects to be treated and recharged from a dust discharging port into the upper part of a separating part, making into contact with a sensor before being uniformly leveled on the separating part according to shaking so that the objects to be treated are detected with the sensor in spite of amount of the objects to be treated and deposited on the upper part of the separating part because the sensor detecting the amount of the objects to be treated and deposited on the upper part of the separating part is arranged just at the rear of the dust discharging port of a dust feeding transportation conveyor (a part for recharging untreated objects into the separating part) (i.e. a part near a treating cylinder of at a dust feeding port and the dust feeding transportation conveyer from the center of the separating part) in a conventional combine harvester and improving the treatment capacity (separating ability) in the separating part. SOLUTION: The combine harvester is composed by disposing the sensor 51 for detecting the amount of the objects to be treated accumulated on the separating part 17 at the rear part from the dust discharging port 50a of the dust feeding transportation conveyer 50 pivoted in the longitudinal direction of a body of a combine 201, and near a threshing cylinder 21 from the center of the separating part.
