Description

Technical Field

[0001] The present invention relates to the technical field of drilling devices for iron ore mining, in particular to a drilling device for iron ore mining. Background Art

[0002] Iron ore is a key raw material for steel production. Natural ore (iron ore) is gradually separated from the iron through processes such as crushing, grinding, magnetic separation, flotation, and gravity separation. Iron ore is a mineral aggregate containing elemental iron or iron compounds that can be economically utilized. There are many types of iron ore, the main ones used in ironmaking being magnetite (Fe3O4), hematite (Fe2O3), and siderite (FeCO3). When an iron ore sample is dissolved in hydrochloric acid, the iron in it is converted to Fe3+. Under strongly acidic conditions, Fe3+ can be reduced to Fe2+ by SnCl2. After Sn2+ has completely reduced Fe3+, methyl orange is also reduced by Sn2+ to hydrogenated methyl orange, causing it to fade. Methyl orange can therefore indicate the end point of Fe3+ reduction. Sn2+ can also further reduce hydrogenated methyl orange to N,N-dimethyl-p-phenylenediamine and sodium p-aminobenzenesulfonate. Iron ore is an international commodity, a strategic material, and a vital part of the economy.

[0003] After using a mining drilling device to drill holes in iron ore, many crucial mining data can be obtained by analyzing the iron content inside the iron ore, which plays an important role in selecting the mining direction of the iron ore. However, the mining drilling devices commonly available on the market are not convenient for adjusting the advancement of the drilling rod according to the actual requirements of iron ore mining drilling, and it is difficult to control the drilling depth of the iron ore.

[0015] The present invention provides a drilling device for iron ore mining. The drilling device for iron ore mining has the following beneficial effects:

[0016] (1) When the drilling depth of the drilling device for iron ore mining needs to be changed, the fixing bolt is removed using a tool, and then the baffle is removed, the metal sheet is taken out of the sliding groove, and the position of the sliding rod in the sliding groove is moved so that the distance between the sliding rod and the center of the driven gear is changed, and then the metal sheet is re-inserted into the sliding groove to fix the position of the sliding rod, and then the fixing bolt is screwed back into the driven gear to complete the adjustment of the drilling depth;

[0017] (2) When the drilling rod of the iron ore mining device is damaged and needs to be replaced, the two-way threaded rod is rotated so that the two clamping arc pieces move relative to each other and no longer clamp the right end of the drilling rod. The damaged drilling rod can be taken out by pulling the drilling rod to the left. Then a new drilling rod is taken out and inserted from the left. At the same time, the positioning groove is aligned with the positioning rod and inserted so that the drilling rod is inserted into the mounting block. The two-way threaded rod is rotated in the opposite direction so that the two clamping arc pieces move toward each other and clamp the right end of the drilling rod, thereby completing the replacement of the drilling rod.

[0018] (3) The drilling device for iron ore mining clamps a metal sheet in the sliding groove and utilizes the rigidity and good compressive resistance of the metal sheet so that the metal sheet can limit the sliding rod in the sliding groove while also being able to withstand the force exerted on the metal sheet by the sliding rod during the drilling process. Compared with using a conventional threaded rod to limit the sliding rod, the device is more stable and there is no need to worry about the threads on the threaded rod being damaged.
