斗轮式挖掘机工作机构的效率的主要指标是:生产率、单位能容、挖掘力以及机重。这些指标在很大程度上取决于所采用的铲斗型式。研究表明:斗轮传动机构的大部分功率(达50—80%)消耗在铲斗的切削周边切入土壤(土屑从原矿体剥离)上和克服装满铲斗时所产生的各种阻力上。挖掘不同土壤时,这种能量消耗与切削机构的型式及几何形状有关。因此,可预先确定:改善铲斗结构型
The main indicators of the efficiency of bucket wheel excavator working mechanisms are: productivity, unit capacity, digging force, and machine weight. These indicators largely depend on the type of bucket used. Studies have shown that most of the power of the bucket wheel drive (up to 50-80%) is consumed by the various resistances that occur when the cutting edge of the bucket cuts into the soil (peeling from the raw ore body) and when the bucket is full of garments. on. When digging different soils, this energy consumption is related to the type and geometry of the cutting mechanism. Therefore, it can be determined in advance: to improve the bucket structure type
