Problems solved by technology
[0003] However, this artificial random sampling method is greatly affected by human factors when selecting the location of the sampling point, and it is time-consuming and laborious to select the sampling location by manually dividing the grid, so that the representativeness and accuracy of coal sample selection cannot be guaranteed. Unable to accurately assess train coal quality

The invention relates to a device for quickly selecting a coal sampling point for a train, which relates to a device for rapidly selecting the position of a coal sampling point. The purpose is to provide an automatic, wide-applicable and convenient rapid selection device for the sampling point of the train. The train coal sampling point rapid selection device of the present invention includes support columns arranged relatively on both sides of the track, a slide bar arranged between the opposite support columns, a box set on the slide bar, and a rotating actuator fixedly connected to the outer wall of the box body. unit, the axial moving unit fixedly installed in the box, the solar panel fixedly installed on the top of the box, the storage battery fixedly installed in the box, the laser imaging system and the infrared control unit and the infrared remote control, the slide bar is fixed to the support column Connected, the rotating execution unit can drive the box body to rotate around the slide bar, the axial movement unit can drive the box body to move along the slide bar, and the infrared control unit is used to control the rotation execution unit and the axial movement unit.
Description
technical field [0001] The invention relates to a coal sampling device, in particular to a device for quickly selecting the position of a coal sampling point. Background technique [0002] Coal plays an increasingly important role in the world's energy structure, and China's coal demand has been showing a high-speed and stable growth trend. Coal, as a special commodity with a large quantity, has an increasing circulation. Since coal is a heterogeneous mixture, its properties vary greatly depending on the geological conditions, production, processing, transportation and other processes of the place where it is generated. Coal sampling refers to the process of taking a representative coal sample from a specific coal stockpile to determine the coal quality of the coal stockpile. Coal sampling is the most important link in coal quality analysis. To obtain accurate test data, representative samples must be collected. In the prior art, the commercial coal sampling method in the...
