| Zusammenfassung: | A spiral reamer type of dredger for narrow and complex water channel, shallow river and lake, and near sea is composed of electric motor, speed-reducing box, spiral reamer and spiral conveyer which consists of machine base, multi-segment spiral impeller assembly, and cylindrical casing installed to machine base. Said spiral impeller assembly is connected with spiral reamer via shaft coupling. It also includes a torque-limiting coupler between electric motor and speed reducer and a lifting unit. Its advantages are compact structure, light weight, high reliability and no secondary pollution of mud to water region. |
