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.
Key word: scraper loader； drum； planet gear.
