ンサ。[Scope of Claim for Utility Model Registration] A handling depth sensor for detecting the relative position of the tip of a grain culm fed to a threshing device with respect to a handling barrel, which emits ultrasonic waves toward the feeding path of the grain culm. One ultrasonic transmitter and two ultrasonic receivers that receive reflected waves from positions corresponding to both ends of the optimal range of the grain culm treatment depth of the ultrasonic waves emitted from the ultrasonic transmitter. A handling depth sensor for a threshing device, characterized in that the handling depth sensor for a threshing device is configured to detect that the handling depth is appropriate when the reception results of the two ultrasonic receivers are different.
