内容简介：

摘 要往复式给煤机安装在煤仓下口处，在煤矿井下生产中，设置一定容量的煤仓对于保证消峰平谷和高产、高效是十分必要的。往复式给煤机由机架、底板（给煤槽）、传动平台、漏斗、闸门、托辊等组成。当电机开动后经弹性联轴器、减速机、曲柄连杆机构拖动倾料13的底板在辊上作直线往复运动，煤均匀地卸到其他设备上。它可以有效地提高工作面采掘设备的利用率，充分发挥运输系统的潜力，保证连续均衡生产。但是，煤仓窜仓事故在我国煤矿经常发生。窜仓事故常造成设备严重损坏，井下停产，当窜仓煤量较大时，还会阻塞巷道，造成运输巷通风不畅，引起瓦斯爆炸等事故。为了防止和降低煤矿井下煤仓窜仓造成的设备损坏、人员伤亡、阻塞巷道和影响生产等危害，设计了一种用于往复式给煤机的防窜仓装置，从而为煤仓窜仓的防治提供了一个新的途径。关键词：曲柄滑块机构 ；煤仓窜仓 ；防窜仓装置 ；往复式给料机ABSTRACTThe reciprocation type stoker installs in bunker the end openingplace, in the coal mine mine shaft production, the establishmentcertain capacity bunker disappears peak Pinggu regarding the guaranteeand the high production, is highly effective is extremely essential. The reciprocation type stoker by the rack, the ledger wall, the transmission platform, the funnel, the strobe, therequest roller and so on is composed. After the electrical machinerystarts after the flexible coupling, the speed reducer, the crank linkmotion gear drives leans the material 13 ledger wall to make thestraight reciprocating motion on the roller, the coal evenly unloadsto other equipment on. It may effectively enhance the working surfaceexcavation equipment the use factor, fully displays the transportationsystem the potential, guaranteed continuously balanced produces. But, bunker flees the warehouse accident frequently to occur in our countrycoal mine. Flees the warehouse matter same as ever to create theequipment major damage, the mine shaft suspends production, when fleesthe warehouse coal amount is bigger, but also can block the tunnel,creates transports the lane to ventilate impeded, causes accident andso on gas explosion. in order to prevent and reduce coal mine coal bunker channeling the warehouse equipment damage, casualties, Roadway congestion and impact production, and other hazards, for the design of a reciprocating coal channeling anti-aircraft positions devices, for the coal bunker channeling warehouse control provides a new way.
