主权项

1. A sensor for measuring yield harvested by a harvesting machine, the harvesting machine having a clean grain elevator with elevator flights configured to carry grain between a lower sprocket and an upper sprocket disposed within an elevator housing, whereby the elevator flights throw the grain in the direction of the sensor as the elevator flights pass over the upper sprocket, the upper sprocket and the lower sprocket defining an elevator plane, the sensor comprising:
a sensor surface having a first end and a second end disposed above the upper sprocket in a direction parallel to the elevator plane; a support secured to the elevator housing, said support including a resilient flexible member capable of allowing said sensor surface to move upward in translational movement with respect to said elevator housing, whereby said first end and said second end of said sensor surface move a substantially equal distance in substantially parallel relation; whereby the grain thrown by the elevator flights imparts said upward translational movement of said sensor surface.
