Description

[0002] In the field of coal detection and analysis, coal sample preparation and cutting is a very critical link, and its cutting quality directly affects the accuracy and reliability of subsequent coal sample detection results. At present, the traditional coal sample preparation and cutting method has many drawbacks and cannot meet the high requirements of modern coal detection.

[0003] The traditional cutting equipment has low automation degree, and most of the operations need to be completed manually. From coal pile, flattening to cutting and material taking, all rely on manual operation. This not only increases the labor intensity of workers, but also has great randomness in manual operation, which makes it difficult to ensure the consistency and standardization of each cutting operation, further affecting the precision and efficiency of coal cutting. For example, during the manual pile process, due to the different experience and methods of the operators, the shape and uniformity of the pile will be different, resulting in unstable flattening and cutting effect. At the same time, manual material taking is also inconvenient, and the cut coal needs to be manually taken out by the workers, which not only is low in efficiency, but also is easy to cause secondary pollution to the coal sample.
