滚臂铲斗式装岩机在铲斗提升过程中,滚臂沿滚道作纯滚动,为得到一定的装载面宽度,一般均使上座板(其上装置着滚道及提升传动装置)沿一回转中心,左右回转一定的角度。同时为使装载的物料能准确地卸入矿车,又必须使上座板在铲斗卸料之前回正。为了使机构简化,较小的铲斗装岩机均采 In the course of bucket lifting, the roll arm of the roller bucket type rock loader rolls purely along the raceway. In order to obtain a certain width of the loading surface, generally the upper seat plate (on which the raceway and the lifting transmission are arranged) A turn center, turn around a certain angle. At the same time in order to load the material can be accurately unloaded into the tub, but also must make the seat plate back to the bucket before unloading. In order to simplify the organization, the smaller bucket rock loader are mining
