PROBLEM TO BE SOLVED: To enable the detection for collecting crops harvested by a crop harvester in a full state to be carried out accurately by a sensor.SOLUTION: The crop harvester including a harvesting part for harvesting the crops from a field, a conveying part for conveying the harvested crops to the rear side of a machine body, a selection part 41 for selecting the harvested crops, and a collecting part 60 for collecting the harvester crops, further includes a contact-type sensor 75 for detecting the volume of the harvested crops collected by the collecting part 60, at the conveyance-finishing part of a conveyor 41 for conveying the harvested crops to the collecting part 60. The contact-type sensor 75 has a detecting plate 77 supported by the conveyance-finishing part of the conveyor 41 so as to be freely turnable around a horizontal axis center. The detecting plate 77 is arranged so as to be directed to the lower side from the horizontal axis center, and so as to be dislocated to the side approaching to the bottom part of the conveyor 41 according to the detection of the harvested crops.COPYRIGHT: (C)2011,JPO&INPIT【課題】本発明は、作物収穫機による収穫作物の満杯状態で回収するための検出をセンサで精度よく行えるようにすることにある。【解決手段】本発明は、作物を圃場から収穫する収穫部と、収穫作物を機体後方側に搬送する搬送部と、収穫作物を選別する選別部41と、収穫作物を回収する回収部60を備えた作物収穫機において、回収部60に収穫作物を搬送するコンベヤ41の搬送終端部に回収部60に回収された収穫作物の嵩を検出する接触式センサ75を備え、接触式センサ75はコンベヤ41の搬送終端部に横軸心周りに揺動自在に支持された検出板77を備え、検出板77は横軸心より下方に向けて配設されているとともに、収穫作物の検出に伴ってコンベヤ41の底部に近接する側に変位するように配設してある。【選択図】図9
