摘要
连续采煤机是一种集机械、电气和液压为一体的大型复杂系统,在很大程度上与目前国内煤矿普遍使用的掘进机相似，都有履带行走系统、铲煤板、电控箱、液压系统和刮板输送机等。整体布局也很相似，铲煤板在截割头下，刮板输送机从前向后纵贯整机，装载部和输送机共用一个动力。连续采煤机和掘进机的最大区别就在截割部。截割部的动作较掘进机简单，而内部传动及其结构比较复杂，形式也多样化。
本设计研究目的在于进一步熟悉连续采煤机的工作原理，进行更好的改进，并对它的截割部分进行细致分析设计，使其耐用并且省时省力容易装修，使连续采煤机在工作中能够有更好的经济效益。
本设计着重于截割机构的设计并进一步详细计算出传动系统各零件的尺寸及画出装配图。选用的方法主要是机械设计的相关知识，使用到的有材料力学、金属工艺学、CAXA绘图软件等。
关键词：连续采煤机；截割机构；减速箱；滚筒；摇臂。

Abstract
The mining machine is a kind of large-scale complicated system of incorporating machinery, electric and hydraulic pressure into an organic whole continuously, similar to tunnelling machine which domestic collieries generally use at present to a great extent, there are system, shovel coal board, automatically controlled case, hydraulic system and waxing scraper conveyer,etc.. Whole overall arrangement too very similar, shovel coal board in cut, cut head, waxing scraper conveyer once pass through the complete machine backward, loading department and conveyer share a power. The greatest difference between the mining machine and tunnelling machine is cutting the cutting department continuously. Movement to cut person who cut relatively person who tunnel simple, internal transmission, and structure relatively more complicated, forms are diversified too.
Originally design the purpose of studying to lie in further familiar with the operation principle of mining machine every part continuouslying, carry on fine improvement, to to cut, cut part go on careful analysis design it, make it durable saving time, saving effort easy to fit up, make person who mine can have kind economic benefits at work continuously.
Design person who mine focus on, cut design to cut organization and calculate actuator every part size and draw the installation diagram in detail further continuously according to CM-800 type originally. The method to select for use is mainly relevant knowledge that machinery is designed, mechanics of materials, metal technology, CAXA mapping software,etc. used to.
Key words: Mining machine continuously; Cut and cut the organization; Gearbox; Cylinder; Rocker arm
