实践证明。由全苏采矿机械科学研究设计院设计并在其试验工厂制造的2型运输巷道联合清理机,是一种地下矿所需的、高效率的清理机械。然而使用揭露出两个重大缺点:结构复杂的圆筒-铲斗式工作机构,由于潮湿的小块矿岩掉入圆筒内部而经常损坏;在温度大和腐蚀介质条件下,带有复杂控制电路的工作机构的驱动装置经常发生在坑内不能排除的故障,因此清理机由于修理而长时间停工。全苏采矿机械科学研究设计院研制了类 Practice proved. The Model 2 Joint Roadway Cleaner, designed by AllScience Mining Machinery Research Institute and manufactured at its pilot plant, is an efficient and efficient cleaning machine for underground mines. However, the use reveals two major drawbacks: the complicated structure of the bucket-bucket working mechanism, which is often damaged by the ingress of damp small pieces of ore into the cylinder; complex control circuits with high temperature and corrosive media The driving mechanism of the working mechanism often occurs in the pit can not be excluded fault, so the cleaning machine due to repair and long time downtime. All Su mining machinery scientific research and design institute developed a class
