Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal mine sampling, in particular to a metal mine debris sampler. Background Art
[0002] Metal mines refer to mines that specialize in mining metal mineral resources, mainly including non-ferrous metals and precious metals such as gold, silver, copper, iron, aluminum, and zinc. The mining process of these mines involves multiple links such as geological exploration, rock drilling and blasting, mine construction, and mineral processing.
[0003] Before mining a metal mine, it is necessary to sample and test the metal ore components inside it to determine whether it is worth mining. When sampling, it is necessary to use a drill to drill holes on the surface of the metal mine. The debris discharged from the drill hole is the sampling sample. The operator needs to test these debris to see if there are mineable metal components.
[0004] However, when a drill drills a hole in the surface of a metal mine, not only may metal debris be drilled out, but the metal debris will also be drilled into debris along with dust by the drill. Operators need to collect these debris mixed with the dust to prevent the on-site picking from easily missing some metal samples. However, before the subsequent metal inspection, the metal mixed with dust needs to be cleaned. This step increases the labor intensity of subsequent inspection personnel. At the same time, some more active metals may react when encountering water, which can easily reduce the accuracy of the subsequent inspection results of the finished product. In view of this, a metal mine debris sampler is provided to overcome the above-mentioned defects. Utility Model Content

[0009] As a further description of the above technical solution: the cross-sectional shape of the frame is an isosceles trapezoid, and the frame has two inclined surfaces distributed at the front and rear positions inside the sorting box. The left and right length of the frame is the same as the length from left to right inside the sorting box, so that metal debris falling on the first screen, the second screen and the third screen can follow the inclined surface to move toward the receiving plates arranged on the front and rear surfaces of the sorting box.

[0011] As a further description of the above technical solution: the pore size of the first screen is three times the pore size of the second screen, and the pore size of the second screen is twice the pore size of the third screen. Debris of different sizes can be sorted, and debris with large particles automatically moves from top to bottom to the receiving plate.
[0012] As a further description of the above technical solution: a plurality of circular holes are opened on the front and rear surfaces of the sorting box, and the diameter and depth of the circular holes opened on the front and rear surfaces of the sorting box are the same as the cross-sectional diameter and length of the magnetic blocks, the circular holes opened on the front and rear surfaces of the sorting box and their distribution are the same as the number and distribution of the magnetic blocks, and the magnetic blocks are used to insert into the grooves on the front and rear surfaces of the sorting box to limit and fix the connecting plate, thereby improving the installation efficiency of the connecting plate.
