刮板机下方原煤采制样一体机的设计与应用

为解决神东煤炭集团公司矿井原煤采制样过程中存在的问题,通过对多个选煤厂现场实地调查,确定了在选煤厂筛分车间配筛刮板机截取断面的方式采取原煤样,结合系统自动化控制等手段,形成一套完整的"选煤厂刮板机下方原煤采制样一体机",实现了原煤机械自动化采制样替代人工采样,并提出了改进方案。 In order to solve the problems existing in the process of raw coal sample preparation in Shendong coal group company,through field investigation in several coal preparation plants,it was determined that the cut-off section of screen scraper conveyor was adopted in the screening workshop of coal preparation plant,and a complete set of " under scraper conveyor of coal preparation plant" was formed by combining with automatic control of the system and other means.Square raw coal sampling and sample machine.The breakthrough of artificial sampling for automatic sampling of raw coal machinery was realized,and the next improvement plan was proposed
