螺旋滚筒在采煤机执行落煤和装煤的工作中起着最为重要的作用,它的功率消耗占采煤机装机功率的80%～90%。其工作机构的形状和几何尺寸参数对整机工作质量有着举足轻重的影响,所以合理地对其进行参数设计尤为重要。从螺旋滚筒的3个直径、螺旋叶片的结构参数2个方面对其进行研究。
The spiral drum plays the most important role in the operation of shearer in coal mining and coal loading. Its power consumption accounts for 80% -90% of the installed power of shearer. The shape and geometry parameters of the working mechanism have a decisive influence on the quality of the whole machine, so it is very important to design the parameters reasonably. From three aspects of spiral drum diameter, spiral blade structural parameters of its research.
