Problems solved by technology
[0004] In view of the related technologies mentioned above, the inventor believes that the sampling method of the screw conveying device and the bucket can only sample the surface layer of the coal pile, and the detection data of the surface coal of the coal pile cannot reflect the quality level of all coal. For example, during the transportation process, the surface layer The water in the coal evaporates more and is relatively dry, while the bottom coal will accumulate more water, resulting in a large error in the test results

The invention relates to a mineral sampling device and a sampling method.The sampling device comprises a sampling device, the sampling device comprises a sampling pipe and a lifting assembly driving the sampling pipe to ascend and descend, a plurality of sampling sections are arranged in the sampling pipe in the length direction and are in sliding fit with the sampling pipe, and a sampling opening is formed in the bottom end of the sampling pipe; a sampling head for supporting the sampling section is arranged on the sampling opening; the collecting device comprises a collecting assembly, the collecting assembly comprises a collecting seat, a supporting column and a plurality of positioning columns are arranged on the collecting seat, the supporting column and the positioning columns are arranged in parallel, a positioning space used for containing the sampling section is formed between the supporting column and the positioning columns, and a dismounting assembly used for separating the sampling head from the sampling pipe is arranged at the bottom of each positioning column. The supporting column is formed by connecting and splicing a plurality of supporting sections end to end, the supporting section closest to the collecting seat is in running fit with the collecting seat, the length of the supporting section is the same as that of the sampling section, and a supporting plate is arranged on the supporting section. The method has the effect of improving the accuracy of coal detection.
Description
technical field [0001] The present application relates to the field of mineral quality detection, and in particular, to a mineral sampling device and a sampling method. Background technique [0002] At present, after the coal production unit produces coal or when the coal user unit buys coal, it is generally necessary to sample and test the coal to detect the quality of the coal. The quality of coal directly affects the price of coal. [0003] In the detection process, sampling is required first, and the sampling method will also have a great impact on the judgment of the overall quality of coal. The existing coal sampling is generally carried out directly in the car or train car, and the coal is collected in the coal pile through a screw conveying device or a bucket. Sampling on. [0004] In view of the above-mentioned related technologies, the inventor believes that the sampling method of the screw conveying device and the bucket can only sample the surface layer of the ...
