Description

Technical Field

[0001] This utility model relates to the field of coal mine quality testing technology, specifically a coal mine quality testing device. Background Technology

[0002] A coal mine is a place or site for mining coal. It is also a reasonable space excavated by humans when excavating geological layers rich in coal, and usually includes roadways, shafts, and mining faces. Coal is the most important solid fuel and a type of combustible organic rock. It is formed by the gradual accumulation of thick layers of lush vegetation in suitable geological environments over a certain geological period, buried at the bottom of water or in silt, and undergoing natural coalification over a long geological period. Coal mine quality testing generally includes four steps: sampling, sample preparation, sample injection, and analysis and testing. First, the coal to be tested is taken, and it is ground into powder using a grinding device. The required weight of coal powder is weighed and placed into a testing instrument for testing. The coal is then identified based on the test data. However, existing coal mine quality testing devices often encounter a significant problem in the pre-processing stage of grinding before coal mine sample testing: large lumps of coal remain, which significantly reduce grinding efficiency, making it difficult to achieve the expected grinding effect. This results in uneven particle size distribution of the coal sample. The presence of large lumps of coal can also easily cause mechanical jamming, excessive wear, or even damage to the grinding equipment during the grinding process. Utility Model Content

[0003] The purpose of this utility model is to provide a coal mine quality testing device to solve the significant problem that existing coal mine quality testing devices often encounter in the grinding pretreatment stage before coal mine sample testing, as mentioned in the background art. This problem is that there are large lumpy coal residues, which significantly reduce grinding efficiency, making it difficult to achieve the expected grinding effect, resulting in uneven particle size distribution of coal samples. The presence of large lumpy coal can also easily cause mechanical jamming, excessive wear, or even damage to the grinding equipment during the grinding process.
