[0003] In the field of port logistics, the screw ship unloader is an important loading and unloading equipment, and the performance of its conveying system is directly related to the efficiency and cost of port operations. In the conveying system of the screw ship unloader, the continuity and stability of the screw shaft are the core elements, which directly determine the smoothness and stability of the material during the conveying process, thus affecting the overall performance of the ship unloader. However, the traditional screw conveying link structure of the screw ship unloader often has many shortcomings in design and manufacturing. First, the installation process is complicated and cumbersome, requiring a lot of manpower and time. This not only increases the manufacturing cost of the equipment, but may also lead to insufficient installation accuracy, affecting the continuity and stability of the screw shaft. Secondly, due to the design limitations of the traditional spiral link structure, its stability is often poor, and it is easily affected by factors such as material properties and workload, resulting in vibration, offset and other problems, thereby reducing the operating efficiency and safety of the ship unloader.
