毕业论文字数：21222 页数：57 带图纸）摘要：刮板输送机是综采工作面配套设备的重要组成部分，是煤炭装运的第一个环节。

Introduced after middle the SGZ730/400 scraper conveyer the trough passes the ear damage simple is reliable,the economical repair craft.

介绍了SGZ730/400刮板输送机中部槽推移耳损坏后简便、可靠、经济的修复工艺。

Therefore, the scraper conveyer delivery capacity has decided the mining coal working surface productivity and the efficiency in a great degree; however, our country was lagged behind at present; the scraper conveyer installing equipment power is small.

因此，刮板输送机的输送能力在很大程度上决定了采煤工作面的生产能力和效率。
