螺旋卸船机多头螺旋垂直提升的研究

Lifting behavior of multi-thread screw ship unloader

对多头螺旋卸船机的提升机理进行探讨．通过对所输送的散体物料的四种典型分布状态的分析，得到了物料的力学模型和求解方法，给出了输送效率和生产率的设计曲线．文中对双头与单头螺旋输送机的参数关系进行了比较，得到的结果是两者有很大差别．多头螺旋垂直输送机应按具体的参数设计．

The characteristic parameters of multi-thread screw ship unloader are studied.Byanalysing four cases of the bulk solids with different free surfaces,the paper proposes amechanical model and provides a solving program,some of the design diagrams for efficiency andproductivity are drawn. DOuble-thread and single-thread screw conveyor are compared.
