Abstract
A crop stream passes longitudinally at a feed velocity varying relative to a predetermined feed velocity in a harvesting machine between conveyor elements which transversely compress the stream and at least one of which is transversely deflectable. A stone in the stream is detected by continuously producing an output corresponding to the transverse deflection of the one conveyor element per unit of time, continuously monitoring the feed velocity and producing an output corresponding to actual feed velocity, and establishing for the predetermined feed velocity a predetermined threshold value for the transverse-deflection output. In addition for actual feed velocities different from the predetermined feed velocity respective threshold values are established that are equal to the predetermined threshold value multiplied by the quotient of the actual feed velocity squared divided by the predetermined feed velocity squared. Action—sounding an alarm, stopping the machine, and/or ejecting the stone—is taken when the transverse-deflection output exceeds the threshold value for the respective actual feed velocity.
