The DRC auger sampling machine is a fast, simple, reliable and economical sampling tool for collecting samples from trains, car compartments, barges and open-air piles. When sampling, the sampling head is drilled into the coal. Under the action of the spiral rotation, the sampler crushes the large block by the drill bit and the pick, and extracts the broken material column, and then rises to the top, then shrinks and shrinks. The subsequent material enters the sample hopper, and the rest of the material returns to the compartment along the outer wall of the positioning tube. The depth of the auger drilling ensures that the full section of the pile is taken.
