Summary:The utility model provides an automatic sampler for a railway wagon conveying coal, sampling a coal sample from the top part of the railway wagon conveying coal. A running trolley mounted on a lifting frame is provided with a sampling shovel. When the trolley moves to the upper part of the set sampling point, the lifting frame is lowered along a door type frame, and a coal shovel positioned on the sampling shovel is inserted into a coal surface for sampling. After the lifting frame is lifted, the sampled coal sample is unloaded into a bucket. The all sampling processes are all automatically operated. The automatic sampler is used for sampling the coal sample whose granularity is 100-0 mm and moisture content is below 13%.
