Description

Technical Field

[0001] The utility model relates to the technical field of limestone mining, in particular to a limestone mining device for a mining area. Background Technique

[0002] Limestone, abbreviated as grey rock, is a carbonate rock mainly composed of calcite, sometimes containing dolomite, clay minerals and clastic minerals, in colors such as grey, greyish white, greyish black, yellow, light red, brownish red, etc., generally not very hard, and having a violent chemical reaction with dilute hydrochloric acid. Classified by origin, it belongs to sedimentary rock.

[0003] In a mining area, limestone samples are often collected through drill pipes. After the mining is completed, the inner core tube needs to be taken out, and then the collected limestone samples are taken out. For some samples stuck inside the core tube, the staff need to tap to make the limestone samples fall off. The inventor believes that the operation process is rather cumbersome and time-consuming and laborious during the process of taking out the limestone samples, especially for some core tubes with longer lengths. Therefore, we propose this limestone mining device for the mining area to solve the above problems. Content of the Utility Model

The mining component includes a drill pipe 3, a drill bit 6, a threaded cover 5 and a core barrel 4. The drill pipe 3 is rotatably installed at the bottom of the movable plate 2. The threaded cover 5 is fixedly installed at the bottom of the movable plate 2 and is located inside the drill pipe 3. The core barrel 4 is installed at the top of the drill bit 6, and a fixing rod 13 extending above the movable plate 2 is fixedly installed at the top thereof.

[0030] Please refer to Figure 5 , Figure 6 and Figure 7 , a sampling component is provided inside the core barrel 4. The sampling component includes a push plate 10 slidably installed inside the core barrel 4. Two installation grooves 7 are provided on the side wall of the core barrel 4. A plurality of springs 8 are fixedly installed on the inner wall of the installation groove 7. The other end of the spring 8 is fixedly installed with a sealing plate 9. Push grooves are provided on the surfaces of the two sealing plates 9. A threaded ring 11 is threadedly installed on the inner wall of the threaded cover 5 and is located outside the core barrel 4. One side of the push plate 10 is fixedly installed with a connecting rod 12 fixed to the threaded ring 11.

[0031] A second driving component for driving the push plate 10 to move and a third driving component for driving the drill pipe 3 to rotate are further provided on the surface of the movable plate 2.

[0032] Among them, the second driving component includes a toothed ring 17 fixedly installed on the surface of the drill pipe 3. A first motor 18 is fixedly installed at the bottom of the movable plate 2. The output end of the first motor 18 is fixedly installed with a first gear 19 meshing with the toothed ring 17.

[0033] In addition, after the drill pipe 3 is reset when the limestone sample collection is completed, only the drill bit 6 needs to be removed, and then the second motor 15 is started to drive the third gear 16 to rotate, so that the core barrel 4 rotates through the second gear 14 and the fixing rod 13. When the core barrel 4 rotates, the connecting rod 12 will rotate synchronously. Since the threaded cover 5 is fixed, the threaded ring 11 and the push plate 10 will move, and the limestone sample inside the core barrel 4 is pushed out of the core barrel 4 by the push plate 10. It is time-saving and labor-saving, and the limestone sample is not easily stuck inside the core barrel 4. Thus, the purpose of conveniently taking out the limestone sample is achieved, and the operation process of taking out the sample is reduced.

[0034] At the same time, through the provided sealing plates 9 and springs 8, the sealing effect of the device when the limestone sample enters the core barrel 4 during the sampling process is improved, so that the sample is not easily separated from the core barrel 4 and enters the inside of the threaded cover 5 during the sampling process.

[0035] It should be noted that, please refer to Figure 8 and Figure 9, inclined grooves are formed on the upper surfaces of both sealing plates 9. The cross-section of the connecting rod 12 is triangular, and the connecting rod 12 is in contact with the inner wall of the inclined groove. Thus, when the connecting rod 12 moves downward, the two sealing plates 9 will move in opposite directions.

[0036] Please refer to Figure 4 , in this embodiment, a connecting groove is formed on the lower surface of the drill pipe 3. A connecting cover 21 extending into the connecting groove is fixedly installed on the upper surface of the drill bit 6. The connecting cover 21 is fixed to the drill pipe 3 by bolts. A sealing sleeve 20 is also fixedly installed on the upper surface of the drill bit 6. The bottom end of the core barrel 4 is rotatably connected to the inner wall of the sealing sleeve 20.

[0037] Among them, through the provided connecting cover 21 and connecting groove, it is convenient for the staff to disassemble the drill bit 6.

[0038] In addition, through the provided sealing sleeve 20, the sealing performance of the drill bit 6 when docking with the core barrel 4 is improved.

[0039] In this embodiment, the third driving assembly includes a second gear 14 fixedly installed at the top of the fixed rod 13. A second motor 15 is fixedly installed at the top of the movable plate 2. The output end of the second motor 15 is fixedly installed with a third gear 16 meshing with the second gear 14.

[0040] Among them, starting the second motor 15 to drive the third gear 16 to rotate can make the core barrel 4 rotate through the second gear 14 and the fixed rod 13.

[0041] It should be noted that the first motor 18 and the second motor 15 in this device are both self-locking motors in the prior art.

[0042] Please refer to Figure 1 , in this embodiment, the mounting table 1 includes a bottom plate 101, a support rod 102 and a top plate 103. The support rod 102 is fixedly installed between the top plate 103 and the bottom plate 101. The first driving assembly includes a third motor 23 fixedly installed at the top of the top plate 103. The output end of the third motor 23 is fixedly installed with a lead screw 24 rotatably connected to the bottom plate 101. A slide rod 22 is also fixedly installed between the top plate 103 and the bottom plate 101. The movable plate 2 is threadedly installed on the surface of the lead screw 24 and is slidably connected to the slide rod 22.

[0043] Starting the third motor 23 drives the lead screw 24 to rotate, and then drives the drill pipe 3 to penetrate into the rock formation through the movable plate 2 for sampling.

[0044] It should be noted that this application also provides an embodiment two:

[0045] Such as Figure 10As shown in the figure, the sealing plate 9 and the spring 8 are replaced with a sealing strip 25, that is, during the movement of the connecting rod 12, the elastic force of the sealing strip 25 makes other positions of the core tube 4 still in a fitting and sealing state. Thus, during the process of the push plate 10 pushing the limestone sample to move, the limestone sample is not likely to enter the inside of the threaded cover 5, increasing the difficulty of later cleaning.

[0046] When this embodiment is in use, start the first motor 18 to drive the first gear 19 to rotate, so that the drill pipe 3 rotates through the toothed ring 17. At the same time, start the third motor 23 to drive the lead screw 24 to rotate, and then drive the drill pipe 3 to penetrate into the rock formation for sampling through the movable plate 2. After sampling is completed, reset the drill pipe 3, remove the drill bit 6 by removing the bolts, and then start the second motor 15 to drive the third gear 16 to rotate, so that the core tube 4 rotates through the second gear 14 and the fixed rod 13. When the core tube 4 rotates, the connecting rod 12 will rotate synchronously. Since the threaded cover 5 is fixed, the threaded ring 11 and the push plate 10 will move, and the limestone sample inside the core tube 4 is pushed out of the core tube 4 by the push plate 10. It is time-saving and labor-saving, and the limestone sample is not likely to be stuck inside the core tube 4. Thus, the purpose of conveniently taking out the limestone sample is achieved, the operation process of taking out the sample is reduced, and the practicability of the device is improved.
