进行斗轮挖掘机设计时,除矿区地质条件外,采矿工艺参数(如生产能力Q、采高H、采宽B,最大推进距离S和边坡角a等)是确定斗轮机主要参数(如斗轮直径D、斗轮中心至机器回摆中心水平距离L_A、斗轮切割速度V_u、斗轮回摆线速度V_s、回摆角度β、斗轮自由切 In the design of the bucket wheel excavator, in addition to the geological conditions of the mining area, the mining process parameters (such as production capacity Q, mining height H, mining width B, maximum propulsion distance S, and slope angle a, etc.) are the main parameters for determining the bucket machine (eg, Bucket diameter D, horizontal distance between the center of the bucket wheel and the center of the machine’s swing back, L_A, bucket wheel cutting speed V_u, bucket wheel back-cycloid speed V_s, back swing angle β, bucket wheel free cutting
