Waveguide driving device and dual-polarized waveguide device

The utility model discloses a waveguide driving device and a dual-polarized waveguide device. The main box body is communicated with the receiving and transmitting module, and the feed source horn and the rotating shaft system are connected and then penetrate through the main box body to be connected with the circular polarizer. A driving motor gear module, a limiting module and a controller are arranged in the waveguide driving device, the limiting module comprises two sensor pressing sheets and a sensor PCB, and the sensor PCB is connected with the driving motor gear module. The driving motor gear module is meshed with the rotating shaft system, and a limiting boss is arranged on the rotating shaft system. The driving motor gear module drives the rotating shaft system to rotate until the limiting boss makes contact with the sensor pressing piece and then is connected with the sensor PCB, the sensor PCB sends out a stop signal, and the driving motor gear module is promoted to stop driving.
