Beschreibung
Zusammenfassung:	The utility model relates to the technical field of screw rotors, and discloses a composite screw rotor, which comprises a first screw rotor and a second screw rotor matched with the first screw rotor, and the two ends of the first screw rotor and the two ends of the second screw rotor are detachably provided with butt joint parts; inserting structures capable of being matched with one another are arranged among the first screw rotor, the second screw rotor and the butt joint component, and the butt joint component can be in butt joint on the first screw rotor and the second screw rotor or be separated from the first screw rotor and the second screw rotor through the inserting structures. According to the utility model, after the butt joint part is inserted into the two ends of the first screw rotor and the second screw rotor through the insertion structures, the shaft rods at the two ends of the first screw rotor and the second screw rotor can be lengthened, and the size and the length of the butt joint part
