In the logistics industry mature developed now, the use of artificial discharging is unwise and unrealistic, the development of automation equipment for screw ship unloader appear in people's field of vision, the main principle is to use the continuous conveyer, independent material feeding, various material cabin is put forward. In this way, the unloading efficiency can be greatly improved, and there will be no pollution during the unloading process, which is clean and environmental friendly.
