Abstract
A system for detecting a broken or missing grain paddle of an elevator of a combine harvester includes a sensor positioned to either directly or indirectly detect a presence of grain paddles of the elevator, and output signals based thereon. The system also includes a controller that is configured to receive the signals output from the sensor and determine the occurrence of the broken or missing grain paddle as a function of the signals transmitted by the sensor.
Claims6
An agricultural vehicle comprising:
- a grain elevator including a housing and a series of interconnected grain paddles positioned within the housing that are driven in an endless loop;
- a sensor positioned to either directly or indirectly detect a presence of the grain paddles and output signals based thereon;
- and
- a controller that receives the signals output from the sensor and determines the occurrence of a broken or missing grain paddle of the interconnected grain paddles as a function of the signals transmitted by the sensor;
- wherein the sensor measures a force of grain that is thrown by each grain paddle onto a measurement portion of the sensor,
- wherein the controller determines the occurrence of the broken or missing grain paddle when the measured force exceeds a pre-determined predetermined value, and
- wherein the controller alerts an operator of the system to the occurrence of the broken or missing main paddle.
