The utility model relates to a transmitting device for navigation container CT detection. The utility model discloses a composite rotary transmitting workbench which is used for navigation container CT detection. The composite rotary transmitting workbench includes a transmitting component and a rotary support component; wherein the transmitting component is arranged on the rotary support component which is fixed on the ground of a transmitting passage for CT detection and scanning. The utility model makes a detected large-size navigation container not only go trough a scanning passage, but also automatically rotate in the scanning passage, thus making a radial scanning device kept still, and improving the work reliability of the radial scanning detection device.
