Description

Technical Field

[0001] The utility model relates to the technical field of bulk coal block sample collection, and more specifically, to a bulk coal block sample collection device. Background Art

[0002] In the existing bulk coal block sampling device technology, sampling is a key link, which is used to take out representative samples from a large number of bulk coal blocks for analysis and testing. However, the existing clamping sampling method has certain limitations. Due to the different shapes and sizes of coal blocks, the existing clamping sampling method usually uses two parallel clamps for sampling and fixing. This method is easy to cause damage to the coal block during operation, thus affecting the sampling effect. When the coal block is irregular in shape or large in size, it is difficult for the two parallel clamps to fully adapt to the shape of the coal block, resulting in loose clamping or uneven clamping force, which in turn causes the coal block to break or deform. This not only affects the accuracy of sampling, but may also cause changes in the physical properties of the coal block, thereby affecting subsequent analysis results. Utility Model Content
