The plow head is coal pl ough 's prime anization, which has distinguishes between the other machinery' s important technical feature. Along with the national coal quantity' s reduction, shallow coal seams ha ve e the new development resource. The coal pl ough which stand for the mining machinery' s development is getting more and more important. However automated coal pl ough basically by overseas monopoly, domestically produced coal pl ough faced with huge challenge. Setting the sliding plough as an example,the dissereation has carried on the study about the main working condition parameter of the coal plough-cutting depth ,planing rate,the struction of the plow head and force analysis. T his article also put forward a new caculating method . After the proof examination, know ing that this design is practical and feasible. Key words : sliding plough ; plow head ; reducer ; force analysis 优秀机械毕业设计欢迎下载,学****交流加 QQ197216396 专业机械设计解君之忧 3 目录引言…………………………………………………………………….1 1. 刨煤机的总体方案设计……………………………………………… 2 适用条件………………………………………………………….. 2 机型选择………………………………………………………….. 2 后牵引拖钩式刨煤机………………………………………….3 前牵引滑行式刨煤机………………………………………….3 后牵滑行-拖钩式刨煤机…………………………………….3 主要结构部件选择………………………………………………… 3 输送机构的型式选择……………………………………………… 4 除尘装置的型式选择…………………………………………….. 4 . 主要技术参数: ………………………………………………….5 2 刨煤机系统原始资料和工况参数…………………………………….6 系统原始资料…………………………………………………….. 6 刨煤机工况参数………………………………………………….. 7 3. 刨煤机系统工作方式………………………………………………… 9 4. 刨速与链速的确定…………………………………………………. 10 4. 1 高速刨煤法工况中刨速与链速的确定……………………… 10 5. 刨头结
