AGRICULTURAL COMBINE HARVESTER WITH HARVESTING AND WINNOWING OPTIMIZATION CONTROL SYSTEM

摘要

An agricultural combine has a threshing assembly for threshing a crop to produce chaff and grain, a cleaning assembly for removing the chaff from the grain, and a control system. The threshing assembly and the cleaning assembly operate at threshing and cleaning settings, respectively, for tending to produce a balance between a threshing load applied across the threshing assembly and a cleaning load applied across the cleaning assembly that tends to have a favorable influence on grain loss. The control system is for sensing an imbalance between the threshing load and the cleaning load tending to have an unfavorable influence on grain loss, and for concurrently adjusting the threshing and cleaning settings of the threshing and cleaning assemblies, respectively, for tending to convert the imbalance between the threshing and cleaning loads to a balance between the threshing and cleaning loads tending to have a favorable influence on grain loss.

主权项

1. An agricultural combine, comprising:
a frame; ground engaging machinery for propelling the frame through a field; a threshing assembly for threshing a harvested agricultural crop to produce chaff and grain; a cleaning assembly for removing the chaff from the grain; the threshing assembly and the cleaning assembly for operating at first and second settings, respectively, for tending to produce a balance between a threshing load applied across the threshing assembly and a cleaning load applied across the cleaning assembly that tends to have a favorable influence on grain loss; a control system, operatively coupled to the threshing assembly and the cleaning assembly, for sensing an imbalance between the threshing load and the cleaning load tending to have an unfavorable influence on grain loss, and for concurrently adjusting the first and second settings of the threshing assembly and the cleaning assembly, respectively, for tending to convert the imbalance between the threshing load and the cleaning load to a balance between the threshing load and the cleaning load tending to have a favorable influence on grain loss.
