くなしたとを特徴とする田植機の自動操向装置。[Scope of Claim for Utility Model Registration] An automatic rice transplanter that uses an ultrasonic sensor to detect the relative positional relationship between the machine and a row of already planted seedlings, and based on this result, moves the machine along the row of already planted seedlings. In the steering device, the ultrasonic sensor is made to protrude laterally in the traveling direction of the aircraft body, and its detection area is oriented in the traveling direction of the aircraft body, and at least one of the two seedlings closest to the already planted seedling row to be detected is aligned. automatic operation of a rice transplanter, characterized in that a plurality of sensors are arranged in parallel so as to face downward as much as possible within the range where they are constantly detected, and the steering is controlled based on whether or not seedlings are detected by each sensor. direction equipment.
