摘要
A yield monitoring system for a grain harvesting combine includes a volume monitor, a moisture monitor, a test weight monitor, a ground speed monitor, and a computer which receives signals from each monitor and continuously derives harvested grain yield rates from those signals, displays the yield rates on a visual display and records the yield rate information for later recall and transfer to other computers. A GPS receiver linked to the system enables it to map yields geographically in the harvested field. The volume monitor receives all grain exiting the clean grain elevator of the combine and passes it through a paddlewheel, the angular displacement of which is monitored over time. The moisture monitor and test weight monitor are mounted to the exterior of the clean grain elevator and receive samples of grain from the lift side of the clean grain elevator.
