大新铅锌矿井下矿石漏斗的斗口设备过去很简单,仅用二件轻型铁轨锻弯成羊角形,埋在斗口处,再用几块厚木板放在羊角形处拦矿石。放矿时用人工把托着矿石的木板一块一块取出,再用钢钎撬着矿石流到车斗。显然这种方式劳动强度既大,效率又低下。为了解决这一问题,我们因地制宜,通过理论分析和试 Daxin lead-zinc mine underground ore funnel bucket mouth equipment in the past is very simple, only two light rail forging into a crooked, buried in the bucket mouth, and then a few pieces of thick wood on the crescent-shaped bar to find ore. Ore when the man with the ore holding a piece of wood taken out, and then use steel brazing ore flow to the car bucket. Obviously, this method is labor-intensive and inefficient. In order to solve this problem, we have adapted our own conditions and analyzed and tested through theory
