Abstract
A combine harvester having a rotary threshing and separating mechanism is disclosed wherein a grain loss sensor is mounted to one side of the threshing and separting mechanism such that separated grain is propelled onto the sensor by the threshing and separating mechanism. The sensor is vertically mounted in an impervious casing for the rotary threshing and separating mechanism to sense the grain being separated just before the crop material is discharged from the combine.
Claims7
In a combine harvester having a mobile frame;
- a rotary threshing and separating means mounted on said frame within a housing to thresh and separate grain from crop material received thereby, said rotary threshing and separating means including a discharge opening through which crop material is discharged therefrom to be removed from said combine harvester, the improvement comprising:
- grain loss sensor means mounted to one side of said rotary threshing and separating means to permit grain which has been separated from crop material within said rotary threshing and separating means, prior to being ejected through said discharge opening, to strike said grain loss sensor means and create a signal indicative of the grain entrapped within the crop material to be ejected through said discharge opening, said grain loss sensor means including a sensor forming a part of said housing.
