Description

Technical Field

[0002] Because coal is a heterogeneous material, its heterogeneity is mainly determined by variations in indicators such as moisture, ash content, and particle size. After coal enters the plant, it needs to be sampled, crushed, and tested. Currently, the conventional sampling method requires two workers: one holding an electric screw sampler and the other holding a sampling cylinder. The inlet of the electric screw sampler is inserted into the coal pile, and the sampling cylinder collects the coal sample discharged from the outlet of the electric screw sampler. After multiple sampling points, the samples are poured into a crusher for further crushing and testing.

[0003] Conventional sampling methods have the following drawbacks: electric spiral samplers are relatively bulky, making them difficult to carry, transfer, and hand-held for sampling, and inconvenient to use; they require two people to work together, which consumes a lot of labor and increases labor costs; electric spiral samplers can only collect surface coal samples, and the collected coal samples are not representative.

[0004] Based on the above technical problems, the inventors proposed a coal sampling and crushing device for coal entering the plant, which can sample coal during the coal entering the plant. The sampling is convenient and labor-saving, and only one person is needed to operate it. At the same time, since the sampling is carried out during the transportation process, the coal sample collected is no longer limited to the surface layer, and the coal sample is more representative.
