摘    要
      本文针对我国西北地区矿井的特点，为了适应大断面斜井快速掘进的要求，从而解决装载速度不能满足掘进速度要求的矛盾，进行了耙斗装岩机的整机设计。论文中以耙斗装岩机的生产率和钢丝绳的牵引力为已知条件，通过大量的计算、推理和论证，基本完成了耙斗装岩机的减速器、工作滚筒、空程滚筒等主要部件的设计工作。其中工作滚筒和空程滚筒的传动部分采用行星齿轮机构来完成，具有操作省力、灵活，调整简便，事故少，维修工作量小的优点，同时在吸取成型产品生产和使用经验的基础上进一步设计和选用了耙斗装岩机的台车、操作机构、刹车机构、耙齿和料槽等部件，继而最终完成了整台耙斗装岩机的设计工作，此外本文还总结了耙斗装岩机的操作方法以及使用和维护注意事项。
此装岩机具有效率高、结构简单，应用范围广等特点。不仅可用在平巷装岩，还可以用在30度以下上山或下山巷道装岩，以及拐变或90度拐弯的巷道，并且还能进行掘进工序的平行作业，提高掘进速度，是实现巷道掘进机械化的一种主要机械设备。

ABSTRACT

In order to meet the demand of the scraper loader the big cross section slant hole high-speed driving tunneling speed, then solve the contradiction of the loading speed not to be able to satisfy the tunneling speed, this article in allusion to the characteristic of our country northwest area mine pit, pays attention studies and the transformation loads the machinery a scraper loader. in this paper, take  the scraper loader’s productivity and the steel wire’s traction as the datum, through the massive computations, the inference and the proof, basically completed the scraper loader the reduction gear, the work drum, the spatial regulation drum and so on the majo`ccident little maintain work, at the same time, on the basic of shaping the absorption the product production and experience of using, design and select the rake to fight part and so on charging machine trolley, operating mechanism, brake mechanism, rabble blade and material trough, subsequently, complete the design work of the scraper loader, in addition, the author also summarized operating procedure of the scraper loader and the attentions which must be paid when using and maintaining the scraper loader.
This harrowing bucket loading grab has the characteristics of high efficiency, simple structure and wide applicable range. It can used for loading not only in horizontal way, but also in inclined way with a angle of inclination which is less than 30 to go up or down, in crooked way or 90 crooked way. It can also do the parallel operation of driving procedures, quicken the driving speed, so it is a main machinery equipment to achieve the mechanization of driving way.
