Automatic gear steering engine of unmanned ship

The utility model discloses an automatic gear steering engine of an unmanned ship. Mainly solves the problem that the use cost is increased due to the fact that most gear switching structures of the existing unmanned surface vehicle are relatively complex. The device is characterized by comprising a rotating shaft (1), a swing rod (2) driven by the rotating shaft to swing is arranged on the rotating shaft, a connecting rod (3) is connected to the swing rod, and one end of the connecting rod is used for being connected with a gear rod (9) of a gearbox; the swing rod comprises a forward gear position for driving the gear rod to incline forward through the connecting rod; the gear rod is driven by the connecting rod to be perpendicular to the neutral gear position of the horizontal plane; and at the backward gear position, the gear rod is driven by the connecting rod to lean backwards. The utility model provides an automatic gear steering engine of an unmanned ship, which can conveniently control gear change, an
