Description

technical field

[0001] The invention relates to the technical field related to coal mining, in particular to a sampling device for coal mining that is convenient for cleaning debris. Background technique

[0002] Coal is the food of industry, and its supply is directly related to the stable development of the industry and even the entire society. Coal is mostly buried underground. Deep coal is sampled for subsequent detection and analysis.

[0003] However, when coal is collected and sampled, the coal collection and sampling device used under the background of the prior art still has certain shortcomings, such as:

[0004] 1. The existing coal collection and sampling devices, when assembled and installed, mostly use threaded connections to install between the sampling pipes, which reduces the convenience of installation and operation and increases the work difficulty of construction personnel;

[0005] 2. The existing coal collection and sampling device is not convenient f...
