Improvement of Loading Structure Design for Small Diameter Spiral Drum in Thin Coal Layer
TAO Rong
Abstract：In order to change the current situation of poor loading effect of small diameter drum in thin coal seams,starting from the coal loading principle of the spiral drum of the coal winning machine,the traditional design characteristics of the main blade and loading blade in the drum design were studied,the defects of the traditional design were analyzed,and the possible reasons for the poor loading effect of small diameter drum were pointed out.By partially improving the structural design of the tail of the drum blades,the cutting blades,loading blades,and plow coal plate are welded together in a semi-closed structure,effectively suppressing coal from being thrown out from the tangential direction of the drum,reducing dust production,improving the loading capacity of the drum,and achieving an increase in loading rate.
