The invention relates to the technical field of propellers and discloses a split-type propeller structure. The split-type propeller structure comprises a propeller hub and a plurality of propeller blades which are uniformly distributed on the propeller hub, wherein the plurality of propeller blades are installed on the propeller hub through welding; the propeller hub comprises a propeller hub body and a shaft hole formed in the propeller hub body, wherein a key slot is formed along the axial direction of the shaft hole; the propeller blades are plate-shaped structures, and the blade surfaces of the propeller blades are structures with gradually increasing width and gradually decreasing thickness from positions of 0.2 time to positions of 1 time of the radius of the propeller; the blade surfaces of the propeller blades are flat sheet structures with thickness of the two ends less than the thickness of the middle portion. By adopting the structure that the propeller hub and the propeller blades are separately manufactured and then welded together, the manufacturing difficulty is recued, the manufacturing accuracy can be guaranteed and the manufacturing efficiency is improved.
