Research on the Structural Optimization Design of Spiral Drum of Coal Mining Machine
Spiral drum is a key structural component in coal mining machine,and its performance directly determines the efficiency of coal mining.The spiral drum of JMG2 × 80(55)/360(260)-WDK coal mining machine is analyzed as an object,and on the basis of the actual working condition of the spiral drum,the optimized design scheme of adding four cut-off teeth in the end cover is proposed.Using EDEM discrete element software to establish finite element models and conduct comparative studies,it is found that the productivity of the new structure has been increased by 13.6％,and the energy consumption of the cut-off ratio has been reduced by about 15％.The optimized spiral roller is applied to the coal mining machine,and through data comparison,it is found that the new structure can really improve the productivity and reduce the energy consumption to a certain extent,which verifies the feasibility of the optimized design scheme.
