TARGET FOR GRAIN TANK LEVEL SENSOR INTEGRATED INTO THE GRAIN TANK

A system (100, 102) is provided for sensing harvested grain levels within an agricultural harvester (10). The system (100, 102) includes a grain tank (28) configured to receive harvested grain, a sensor (90, 318) configured to emit a sensor beam (90A, 90B) into the grain tank (28) for reflection off...

Zusammenfassung:	A system (100, 102) is provided for sensing harvested grain levels within an agricultural harvester (10). The system (100, 102) includes a grain tank (28) configured to receive harvested grain, a sensor (90, 318) configured to emit a sensor beam (90A, 90B) into the grain tank (28) for reflection off of the top surface of the harvested grain, and a reflective target (92A, 92B, 126, 205, 208) integrated into a bottom surface (93A, 93B, 94A, 94B) of the grain tank (28) at a minimum detectable grain level within the grain tank (28). The bottom surface (93A, 93B, 94A, 94B) of the grain tank (28) being angled towards the sensor (90, 318), the minimum detectable grain level being defined by a minimum grain level within the grain tank (28) at which the top surface of the harvested grain is contacted by the sensor beam (90A, 90B), and the reflective target (92A, 92B, 126, 205, 208) being configured to reflect the sensor beam (90A, 90B) when the current grain level is vertically below the minimum detectable grain level.
