Description

Technical Field

[0001] This utility model relates to the field of iron ore exploration technology, and in particular to an iron ore exploration sampling device. Background Technology

[0002] Mineral exploration is the work of discovering and identifying industrial mineral deposits. To do this, it is necessary to use exploration methods such as geological mapping, geophysical exploration, geochemical exploration, drilling and pit exploration, to conduct sampling analysis, study ore quality, delineate ore bodies using industrial indicators and calculate reserves, study the technical performance of ore beneficiation and metallurgy and the hydrogeological and engineering geological conditions for mining, make technical and economic evaluations of mineral deposits and prepare geological exploration reports.

[0003] Iron ore is a mineral area rich in iron ore. Iron ore mining is often accompanied by the mining and screening of other ores. Therefore, mineral exploration operations for iron ore and its associated minerals are required in the mine. The current exploration method is to directly drill and sample, and then analyze the sampled minerals. However, due to the non-ore layer covering the surface of the mine, direct drilling and sampling will collect a large amount of non-ore layer material in the early stage of sampling, which will affect the accuracy of sampling at the exploration location. Utility Model Content

[0004] To solve the aforementioned technical problems and achieve the requirement of discarding the surface soil and only taking samples from a predetermined depth for exploration, this application proposes the following technical solution:

[0005] A sampling device for iron ore exploration includes a base frame with an operation box mounted on it. The operation box has a circular hole through which a feed pipe is movably connected. A sampling component is mounted at one end of the feed pipe. The sampling component includes a sampling tube and multiple movable outer tubes. One end of the sampling tube is fixedly connected to the feed pipe, and the outer side of the sampling tube has multiple circumferentially spaced grooves. The multiple movable outer tubes are movably connected to the multiple grooves. One end of each movable outer tube is fixedly connected to a central plate, which is movably connected to the sampling tube. External spiral blades are mounted on the outer sides of the sampling tube and the movable outer tubes. A drill bit is fixedly connected to the top of the sampling tube. Multiple feed troughs are located within the multiple grooves on the sampling tube.

[0006] Preferably, the sampling tube is externally fixedly connected to a rear retaining plate and a front retaining plate, which are located on both sides of the central plate. Each of the rear and front retaining plates has three circumferentially spaced slots on its opposite side. Slots are also provided on both sides of the central plate. Furthermore, three limiting rods are movably connected between the central plate and the rear or front retaining plate.

[0007] Preferably, a heating sleeve is fixedly connected to the outside of the conveying pipe, and an electric heating wire is provided inside the heating sleeve.

[0008] Preferably, the material conveying pipe is externally fixedly connected to a sleeve gear, and the operating box is internally fixedly connected to a motor. The output end of the motor is connected to a short shaft via a coupling, and the other end of the short shaft is fixedly connected to a drive gear. The drive gear meshes with a intermediate gear via a tooth groove. A short rod is fixedly connected to one side of the intermediate gear, and the other end of the short rod is movably connected to the operating box. The intermediate gear meshes with the sleeve gear.

[0009] Preferably, the feed pipe has a shaft inside, a spiral feed plate is fixedly connected to the outside of the shaft, one end of the shaft is movably connected to the inner end of the sampling pipe, the other end of the shaft is fixedly connected to a traction wheel, and a connecting rod is fixedly connected to the central gear. The other end of the connecting rod is fixedly connected to a drive wheel, and the drive wheel is movably connected to the traction wheel.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model, through its base frame, operating box, conveying pipe, and sampling component, allows the device to adjust according to the actual ore layer being explored. Before reaching the preset exploration position, the non-ore layer drilled is discharged from the outside of the sampling pipe and conveying pipe. After reaching the preset exploration position, the drilled ore will enter the sampling pipe and conveying pipe, allowing for targeted ore sampling of the actual ore layer and improving the accuracy of the exploration.

[0012] 2. This utility model uses a rear fixed plate, a front fixed plate, a limiting rod, a heating sleeve, and an electric heating wire. The limiting rod limits and fixes the position of the movable outer tube, which facilitates the adjustment of the position of the limiting outer tube and improves the convenience of device operation. The heating sleeve and electric heating wire can increase the temperature inside the conveying pipe, heat and dry the ore conveyed in the conveying pipe, reduce the internal moisture content, and prevent the ore from clogging the equipment after being mixed with a large amount of groundwater.

[0013] 3. This utility model, through the setting of a sleeve tooth, motor, shaft and spiral feeding plate, utilizes the rotating shaft and spiral feeding plate to facilitate the transportation of minerals entering the sampling tube and conveying tube to the outside. At the same time, the outer wall of the spiral feeding plate has irregular protrusions, which can crush the transported minerals and prevent agglomeration. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] A sampling device for iron ore exploration, such as Figure 1 , Figure 2 and Figure 3As shown, the device includes a base frame 1, an operation box 2 mounted on the base frame 1, a circular hole on the operation box 2, and a feed pipe 3 rotatably connected to the inside of the circular hole via a bearing. A sampling component is mounted at one end of the feed pipe 3, the sampling component including a sampling tube 4 and multiple movable outer tubes 5. One end of the sampling tube 4 is bolted to the feed pipe 3, and multiple circumferentially spaced grooves are provided on the outer side of the sampling tube 4. The multiple movable outer tubes 5 are slidably connected to the multiple grooves. One end of the multiple movable outer tubes 5 is bolted to the same central plate 6, and the central plate 6 is slidably connected to the sampling tube 4. External spiral blades 7 are provided on the outer side of the sampling tube 4 and the movable outer tubes 5, and a drill bit 8 is bolted to the top of the sampling tube 4. Multiple feed slots 9 are provided on the sampling tube 4, and the multiple feed slots 9 are respectively located in the multiple grooves on the sampling tube 4.

[0024] Furthermore, such as Figure 1 and Figure 4 As shown, the sampling tube 4 is externally connected to a rear-positioning plate 10 and a front-positioning plate 11 by bolts. The rear-positioning plate 10 and the front-positioning plate 11 are located on both sides of the central plate 6. Each of the rear-positioning plate 10 and the front-positioning plate 11 has three circumferentially spaced slots on its opposite side. Slots are also provided on both sides of the central plate 6. Three limiting rods 12 are inserted between the central plate 6 and the rear-positioning plate 10 or the front-positioning plate 11. The limiting rods 12 are used to limit and fix the position of the movable outer tube 5, which facilitates the adjustment of the position of the limiting outer tube and improves the ease of operation of the device. The conveying pipe 3 is externally connected to a heating sleeve 13 by bolts. The heating sleeve 13 is equipped with an electric heating wire 14. The heating sleeve 13 and the electric heating wire 14 can increase the temperature inside the conveying pipe 3, heat and dry the minerals conveyed in the conveying pipe 3, reduce the internal moisture, and prevent the ore from clogging the equipment after being mixed with a large amount of groundwater.

[0025] Furthermore, such as Figure 1 , Figure 4 and Figure 6As shown, a sleeve gear 15 is bolted to the outside of the conveying pipe 3. A motor 16 is bolted to the inside of the control box 2. The output end of the motor 16 is connected to a short shaft via a coupling. The other end of the short shaft is bolted to a drive gear 17, which meshes with a secondary gear 18 via tooth grooves. A short rod is bolted to one side of the secondary gear 18, and the other end of the short rod is rotatably connected to the control box 2 via a bearing. The secondary gear 18 meshes with the sleeve gear 15. A shaft 19 is installed inside the conveying pipe 3, and a spiral feed plate 20 is bolted to the outside of the shaft 19. One end of the rod 19 is rotatably connected to the inner end of the sampling tube 4 via a bearing. The other end of the rod 19 is bolted to a drive wheel 21, and a connecting rod 22 is bolted to the central gear 18. The other end of the connecting rod 22 is bolted to a drive wheel 23. The drive wheel 23 and the drive wheel 21 are rotatably connected via a belt. The rotating rod 19 and the spiral feed plate 20 facilitate the transport of minerals entering the sampling tube 4 and the conveying tube 3 to the outside. At the same time, the outer wall of the spiral feed plate 20 has irregular protrusions, which can crush the transported minerals and prevent agglomeration.

[0026] Furthermore, to quickly screen out the desired ore samples from the sample, screening components can be set up, such as... Figure 5 , Figure 6 and Figure 7As shown, the control box 2 is equipped with a handle 24, and a rubber pad is fitted over the handle 24. A bracket 26 is bolted to the lower side of the control box 2, and a screening assembly is mounted on the bracket 26. The control box 2 has a circular hole, and a rail 25 is slidably connected inside the hole. Both ends of the rail 25 are bolted to the base frame 1. The lower end of the bracket 26 has two symmetrical circular holes, and sliding rods 27 are slidably connected inside each hole. Both ends of the sliding rods 27 are bolted to the base frame 1. The screening assembly... The system includes three screening plates 28, two screens 29, and a sliding plate 30. The three screening plates 28 are equidistantly distributed on one side of the control box 2. Each of the three screening plates 28 has rectangular recesses. The two screens 29 are bolted to the rectangular recesses on the two upper screening plates 28, and the sliding plate 30 is bolted to the rectangular recesses on the lowermost screening plate 28. One end of each of the three screening plates 28 is bolted to a discharge slope 31. The screening assembly can be used to screen the sampled minerals. The mesh sizes of the screens 29 are different, with the upper screen 29 having a larger mesh. Each of the three screen plates 28 has four symmetrical circular holes, and each hole has a sliding support rod 32. The bottom end of the support rod 32 is bolted to the bracket 26. Symmetrical return springs 33 are bolted to all three screen plates 28, as well as to the lowermost screen plate 28 and the bracket 26. A connecting boss 34 is bolted to the upper side of the uppermost screen plate 28, and a short rod is bolted to the outside of the drive gear 17. The other end of the rod is connected to a cam 35 by bolts. The cam 35 is located directly above the connecting boss 34. Each of the three sieve plates 28 is provided with a material distribution plate 36. The material distribution plate 36 is located below the material drop slope 31. The three material distribution plates 36 are all connected to the base frame 1 by bolts. The cam 35 is rotated by a motor 16 to apply the driving force to the sieve plates 28. The reset spring 33 is used to provide the driving force for the vibration of the sieve plates 28, which facilitates the sieving operation of the screen 29 and is beneficial for subsequent analysis and observation of the sample.

[0027] Working principle: The device is used for mineral exploration in the mine tunnel. After the base frame 1 is set up at the exploration location, the motor 16 is started. The motor 16 uses gears to drive the material conveying pipe 3 and the sampling pipe 4 to rotate. The operator holds the handle 24 and pushes it forward. The drill bit 8 drills (at this time, the limit rod 12 is located between the rear fixed plate 10 and the middle plate 6, and the movable outer pipe 5 covers the feed chute 9). Surface dust and other materials generated during the drilling process are sent out by the external spiral blades 7.

[0028] After drilling to the preset depth, the motor 16 is turned off, the limiting rod 12 is removed, and the central plate 6 is moved to the rear fixed plate 10. The movable outer tube 5 moves along with the central plate 6, and the feed chute 9 is exposed. The limiting rod 12 is inserted between the central plate 6 and the front fixed plate 11 for fixation. The motor 16 is restarted to continue the drilling operation. The drilled minerals will enter the sampling tube 4 through the feed chute 9 during the subsequent conveying process of the external spiral blades. The shaft 19 inside the sampling tube 4 is continuously rotating under the drive of the motor 16. The spiral feed blades convey and rotate the minerals that enter the sampling tube 4 until they are discharged from the outer port of the conveying pipe 3 (during the conveying process of the conveying pipe 3, the heating wire 14 is in a heated state to increase the temperature inside the conveying pipe 3 and dry the conveyed minerals).

[0029] To quickly screen out the required ore samples from the sample, a screening assembly can be set up. The discharged minerals will fall directly onto the uppermost screening plate 28. Due to the force of the cam 35, the uppermost screening plate 28 will slide on the support rod 32. The return spring 33 between the screening plates 28 will be compressed and undergo elastic deformation. The return spring 33 at the bottom will apply pressure to the bracket 26. Therefore, the screening plate 28 will vibrate with the movement of the cam 35. The screen 29 screens the minerals falling on it (the two screens 29 have different mesh sizes, with the upper screen 29 having a larger mesh). The screened minerals will eventually fall from the discharge slope 31 onto the bulk plate 36 for collection.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
