Combine harvester

Provided is a combine harvester which, by storing a part of sampled first grains in a storing container, is capable of performing husk removing treatment and the like as appropriate after finishing harvesting the stored first grains, and then accurately measuring the internal quality of the grains. The combine harvester has a grain storing unit for storing selected first grains, and comprises a sampling means for sampling a part of first grains over time, and a sample storing means for sequentially storing the first grains sampled by the sampling means. 本发明提供种联合收割机，其通过将所采集的部分号谷粒收纳在回收容器内，能够在收割作业结束后对所收纳的号谷粒适当地进行脱皮处理等，其后精度良好地进行内部品质的计测。具有用于贮存所筛选的号谷粒的谷粒贮存部的联合收割机包括：时序地采集部分号谷粒的采样单元；和依次收纳由采样单元采集的号谷粒的样品收纳单元。
