DEVICE FOR DETECTING THE PRESENCE OF A CROP FLOW IN A HARVESTING MACHINE

摘要

Disclosed is a sensor for detecting the presence of a crop flow in a harvesting machine. The sensor is designed to emit an output signal containing information on whether crop material is passing through the harvesting machine or not. It is suggested that the sensor be designed to detect vibrations produced during the processing and/o r transporting of the crop flow in the harvesting machine. Such a sensor is especially suitable for use with arrangements for calculating the area from which crop is being harvested and for mapping yields.
