以某一型号的钻式采煤机为研究对象,介绍了其主要构成及工作原理,不同于传统的电机驱动及控制钻式采煤机,该设计采用全液压系统驱动及控制,最后将电机驱动与液压驱动的钻式采煤机性能做对比。结果表明,相对于传统电驱动钻式采煤机,液压采煤机大大提高了采煤的工作效率。 Taking a certain type of coal-winning machine as the research object, the main structure and working principle of the machine are introduced. Different from the traditional motor driven and controlled coal-mining machine, this design uses full-hydraulic system to drive and control. Finally, the motor Drive and hydraulic drive compared to the performance of coal-mining machine. The results show that the hydraulic shearer greatly improves the working efficiency of coal mining compared with the traditional electric driven coal shearer.
