摘要

At the head end of a clean-grain paddle conveyor (12) in a combine harvester, a change in flow direction delivers grain to the foot of the auger (13) whose screw completes transport of the grain to a grain tank. The second part of the change in direction of flow involves the resiliently mounted curved sensing device which is subjected to centrifugal forces from the grain expelled radially as its direction of flow is changed as the paddle chain passes around a sprocket. Movement of the resiliently mounted sensor is detected by a transducer providing a signal proportional to the weight rate of clean-grain conveyed. The sensor with its curves sensing surface is resiliently supported by leaf spring whilst held in a frame disposed on the axis of the sensed force.
