Study of Lacking Picks on Shearer Helical Vane on Drum Load Influence
In order to master load magnitude a drum and its changes under lacking picks condition,find out the influence on drum loads when lacking picks on helical vanes,explore failure reasons of a shearer drum,a mathematical model of shearer drum loads was analyzed and established in the paper,using Matlab computer analysis program,drum loads and their changes under several conditions were simuhited when lacking picks on helical vanes,and the influence to shearer drum load of lacking picks on different positions was analyzed.The results indicate that,the closer lacking pick position to the seam exposed surface,the smaller drum load fluctuation is when existing one lacking pick on helical vane; the load fluctuation and position angle of two lacking picks on the drum inversely proportional when existing two lacking picks on helical vane,which is roughly in accord with the actual situation.
