| 摘 要： | 机械采制煤制样是目前唯一能够采到具有代表性煤样的手段，但国产的机械采制煤样装置存在着全断面采样难和水分适性差两大难题。DJY刮斗式自动采制煤样装置比较好地解决了这两个问题，主要技术性能已接近进口设备的水平。文中介绍了构成机械采制煤样装置的五大件──—采样机、给料机、破碎机、缩分机和余煤运料机的各种型式及要求，提出了应修改我国原有的采制煤样装置技术标准的意见。

| Abstract: | Mechanical sampling for coal conveying system is the only method that could adopt representative coal sample. There are two shortcomings in the domestic mecbanical sampling device - difficult to sample in all section and unsuitable for coal sampling with more water content. DJY scraper type sampIing device have overcome above mentioned short comings. The paper also introduced various components of the device: sampler. feeder,crusher, secondary sampling unit and returning material equipment. |
