Description

Technical Field

[0002] There are often many ore resources in mines, so people will use a variety of mining equipment to carry out mining operations inside the mines. However, before actually carrying out mining operations on the mines, people will conduct an investigation on the specific conditions of the rock formations inside the mines to facilitate subsequent planned mining operations inside the mines. During the process of surveying the inside of the mines, in order to determine the specific composition of the ores inside the mines and facilitate the detection personnel to judge the ore content in different areas inside the mines, when using drilling equipment to survey the mines, it is necessary to sample the ores in the mines.

[0003] In the prior art, the method for sampling deep in the mine will use drilling equipment as an aid. When the drilling equipment drills the mine, since ore debris will continuously be discharged from the drill hole, the detection personnel will regularly collect the ore debris discharged from the drill hole to determine the ore composition at a specific depth in the mine. However, for the ore debris discharged through the drill hole, when the ore debris deep in the hole is discharged from the drill hole, the ore debris deep in the hole will inevitably be mixed with the ore debris in the shallow part. Therefore, for the ore sample taken by this method, only the components contained in the ore in the drill hole can be roughly judged, and it is difficult to detect and judge the proportion of various components in the ore, which affects the accuracy of people's exploration of the mine.

[0027] The working principle and beneficial effects of the present invention are as follows:

[0028] 1. In the present invention, when it is necessary to sample the ore in the mine to realize the mine exploration operation, first, a drilling device is used to drill a borehole in the mine. Then, the installation cylinder is moved to directly above the borehole, and the sampling cylinder is also moved to directly above the borehole. Then, the splicing screw and the sampling cylinder are driven into the borehole by the spiral drive assembly. If it is necessary to make the sampling cylinder extend to a deeper position in the borehole, the splicing screws can be connected to each other so that the sampling cylinder can extend to the designated sampling position in the borehole. Then, the ore sampling assembly is driven to move in the corresponding removal channel by the lateral movement assembly, so that the ore sampling assembly crushes the ore into an ore sample and enters the spiral conveying structure. The ore sample is driven to move by the spiral conveying structure, so that the ore sample enters one of the sampling bottles. The corresponding sampling bottle is driven to be removed by the traction removal assembly, so that the tester can take out the ore sample collected in the sampling bottle for testing, achieving the purpose of mine exploration. And after one of the sampling bottles is taken out, the sampling cylinder can be continuously driven to move deeper into the borehole to continue the sampling operation at other ore sampling locations;

[0029] 2. Therefore, the ore sampling device for mine exploration can operate on multiple ore sampling locations deep in the borehole, sample the ore at different ore sampling locations in the borehole in sequence, and each collected ore sample can be timely removed from the borehole, facilitating the tester to timely test the ore sample.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0045] A spiral driving assembly 100 is arranged in the installation cylinder body 1. The spiral driving assembly 100 is used to drive the splicing screw 2 to move longitudinally. The spiral driving assembly 100 includes a fixed cylinder body 7, a rotating cylinder body 8 and a sliding member 10. The fixed cylinder body 7 is fixedly connected to the upper side inside the installation cylinder body 1. A rotating cylinder body 8 is rotatably connected inside the fixed cylinder body 7. A threaded seat 9 is fixedly connected to the rotating cylinder body 8. The splicing screw 2 is threadedly connected to the threaded seat 9. A rotating assembly is arranged between the rotating cylinder body 8, the fixed cylinder body 7 and the installation cylinder body 1. The rotating assembly includes two bevel gears 38.

A motor driving device 40 is arranged on the fixed cylinder body 7. The output end of the motor driving device 40 is fixedly connected to the driving shaft 39. Two sliding through grooves are symmetrically formed on the splicing screw 2. Sliding members 10 are fixedly connected to both sides inside the fixed cylinder body 7. The sliding members 10 are in contact with the inner walls of the sliding through grooves. When it is necessary to drive the splicing screw 2 to move longitudinally, start the motor driving device 40 to drive the driving shaft 39 to rotate. Drive the rotating cylinder body 8 and the threaded seat 9 to rotate through the meshing relationship of the two bevel gears 38. Through the threaded connection relationship between the threaded seat 9 and the splicing screw 2, and the sliding fit between the sliding members 10 and the sliding through grooves, the splicing screw 2 moves longitudinally in the installation cylinder body 1, driving the sampling cylinder body 3 to move in the drill hole.

[0046] The sampling cylinder body 3 is fixedly connected to the splicing screw rod 2. A plurality of removal channels 4 are formed in the side wall of the sampling cylinder body 3. A spiral conveying structure 200 is arranged inside the sampling cylinder body 3. The spiral conveying structure 200 includes a fixed support cylinder 11, a rotating support cylinder 12, a spiral conveying rod 13 and a first driving motor 14. Fixed support cylinders 11 are fixedly connected to both the inner top wall and the inner bottom wall of the sampling cylinder body 3. The rotating support cylinder 12 is rotatably connected between the two fixed support cylinders 11. A driving assembly is arranged between the rotating support cylinder 12 and the sampling cylinder body 3. The driving assembly includes two transmission gears 41 which are engaged with each other. One of the transmission gears 41 is arranged on the rotating support cylinder 12, and a fourth driving motor 42 is arranged inside the sampling cylinder body 3. The other transmission gear 41 is arranged on the output end of the fourth driving motor 42. When the fourth driving motor 42 is started, due to the meshing relationship of the two transmission gears 41, the rotating support cylinder 12 is driven to rotate between the two fixed support cylinders 11, and the sampling cylinder 17 is moved to correspond to one of the removal channels 4;

[0047] A spiral conveying rod 13 is rotatably connected between the two fixed support cylinders 11. A first driving motor 14 is arranged at the inner bottom of the sampling cylinder body 3. The output end of the first driving motor 14 is fixedly connected to the spiral conveying rod 13. After the ore sample is moved between the two fixed support cylinders 11 and the rotating support cylinder 12, the first driving motor 14 is started to drive the spiral conveying rod 13 to rotate, so that the ore sample moves inside the fixed support cylinder 11 and the rotating support cylinder 12, and the ore sample is moved to the height corresponding to the sampling pipe 5;

[0048] A lateral movement assembly 300 is rotatably arranged on the spiral conveying structure 200. The lateral movement assembly 300 includes a sliding groove body 15 and a bent connecting piece 16. The sliding groove body 15 is fixedly connected to the rotating support cylinder 12. A bent connecting piece 16 is slidably connected inside the sliding groove body 15.

A transmission lead screw 43 is rotatably connected inside the sliding groove body 15. A fifth driving motor 44 is arranged on the sliding groove body 15. Driving gears 45 are arranged on the output end of the fifth driving motor 44 and on the transmission lead screw 43 respectively, and the two driving gears 45 are engaged with each other. When it is necessary to drive the sampling cylinder 17 to move laterally, the fifth driving motor 44 is started to drive the transmission lead screw 43 to rotate through the two driving gears 45, so that the bent connecting piece 16 drives the sampling cylinder 17 to move laterally, and the sampling cylinder 17 enters the removal channel 4. During the movement of the sampling cylinder 17 inside the removal channel 4, due to the special shape design of the bent connecting piece 16, the bent connecting piece 16 can enter the removal channel 4 and drive the sampling cylinder 17 to move out of the removal channel 4 and into the drill hole.

[0049] A ore sampling component 400 is arranged on the lateral movement component 300. The ore sampling component 400 is communicated with the spiral conveying structure 200. The ore sampling component 400 includes a sampling cylinder body 17, a rotating seat 18, a spiral conveying rotating rod 19, a second driving motor 20 and a conveying pipeline 21. The sampling cylinder body 17 is fixedly connected to the bending connecting piece 16. A rotating seat 18 is rotatably connected to the sampling cylinder body 17. A plurality of inlet grooves are formed in the rotating seat 18. One side of the rotating seat 18 close to the moving-out channel 4 is concave. A spiral conveying rotating rod 19 is rotatably connected in the sampling cylinder body 17. The spiral conveying rotating rod 19 is fixedly connected to the rotating seat 18. The second driving motor 20 is arranged on the sampling cylinder body 17. The output end of the second driving motor 20 is fixedly connected to the spiral conveying rotating rod 19. A conveying pipeline 21 is communicated between the sampling cylinder body 17 and the rotating support cylinder 12. When it is necessary to sample the ore in the drill hole, start the second driving motor 20 to drive the spiral conveying rotating rod 19 and the rotating seat 18 to rotate. After the rotating seat 18 contacts the inner wall of the drill hole, the special shape design of the rotating seat 18 can make the concave inner wall of the rotating seat 18 contact the inner wall of the drill hole. As the concave inner wall of the rotating seat 18 gradually contacts the inner wall of the drill hole and the rotating seat 18 rotates, the ore powder rubbed off from the inner wall of the drill hole enters the sampling cylinder body 17 through the inlet grooves. Driven by the spiral conveying rotating rod 19, the ore sample moves and finally enters the rotating support cylinder 12 through the conveying pipeline 21;

[0050] On this basis, in order to enable the ore powder to flow smoothly in the conveying pipeline 21, a sliding frame 48 is fixedly connected to the sampling cylinder body 17.

The eccentric wheel 51 contacts the top of the pushing frame 49. When the ore sample enters the conveying pipeline 21, when the second driving motor 20 drives the spiral conveying rotating rod 19 to rotate, it will synchronously drive the eccentric wheel 51 to rotate, so that the eccentric wheel 51 contacts the top of the pushing frame 49, causing the pushing frame 49 to longitudinally move in the sliding frame 48. Under the action of the spring damper 50, the pushing frame 49 longitudinally moves in the sliding frame 48, enabling the conveying pipeline 21 to maintain a rapid longitudinal movement when conveying the ore sample, so that the conveying pipeline 21 can have a good conveying effect on the ore sample.

The discharge pipe 24 extends into the feed pipe 22, and the discharge pipe 24 is in contact with the inner wall of the friction ring 23. When it is necessary to let the ore sample conveyed inside the fixed support cylinder 11 enter the corresponding sampling tube 5, before moving the fixed cylinder 7 into the drill hole, after moving the sampling tube 5 into the placement cylinder 6, move the discharge pipe 24 into the feed pipe 22, make the discharge pipe 24 contact the inner wall of the friction ring 23, keep the discharge pipe 24 fixed inside the feed pipe 22, open the valve 27 of the corresponding discharge pipe 24, and let the ore sample enter the corresponding sampling tube 5 through the corresponding discharge pipe 24.

[0052] A plurality of sector pieces 25 are arranged inside both the feed pipe 22 and the placement cylinder 6. After the sampling tube 5 is removed from the placement cylinder 6 and enters the drill hole, first, the plurality of sector pieces 25 arranged inside the feed pipe 22 overlap each other, so that the feed pipe 22 remains sealed, preventing other ore components in the drill hole from entering the sampling tube 5. The sector pieces 25 arranged inside the placement cylinder 6 also overlap each other, which is used to prevent the ore components in the drill hole from entering the placement cylinder 6, and the sector pieces 25 do not affect the direct removal of the sampling tube 5 from the placement cylinder 6;

[0053] The top of the sampling tube 5 is communicated with a discharge pipe 26. A valve 27 is arranged on the discharge pipe 26. A discharge port 28 is provided on the discharge pipe 26, and the discharge port 28 is located above the valve 27. After moving the sampling tube 5 into the installation cylinder 1, in order to take out the ore sample inside the sampling tube 5, the valve 27 on the discharge port 28 can be opened, the sampling tube 5 is tilted, and the ore sample is removed through the discharge port 28 on the discharge pipe 26.

A plurality of fixing rings 33 are fixedly connected to the mounting ring plate 32. The traction rope 47 is arranged to be transmitted between the corresponding plurality of fixing rings 33. When it is necessary to remove the corresponding sampling tube 5 from the placement cylinder 6, the third driving motor 31 is driven to drive the winding cylinder 30 to rotate inside the rotating frame 29, so that the traction rope 47 moves between the plurality of fixing rings 33, and the traction rope 47 removes the sampling tube 5 from the placement cylinder 6.

[0055] It further includes a cover 34. A cover 34 is rotatably arranged on each removal channel 4. A elastic torsion structure is arranged between the cover 34 and the removal channel 4.

After the sampling cylinder 17 is removed from the removal channel 4, the sampling cylinder 17 is made to push the cover 34 to flip along the center point of the driving shaft 52, so that the sampling cylinder 17 extends out of the removal channel 4 for sampling operation. After the sampling cylinder 17 is reinserted into the sampling cylinder 3, the cover 34 is reset under the action of the torsion spring 53, and the removal channel 4 is kept closed.

[0056] It further includes removal openings 35. A plurality of removal openings 35 are opened at the bottom of the installation cylinder 1, and the inside of the installation cylinder 1 is operated through the removal openings 35.

Through the threaded connection relationship between the threaded seat 9 and the splicing screw 2, and the sliding cooperation between the sliding member 10 and the sliding groove, the splicing screw 2 is moved longitudinally in the installation cylinder 1, driving the sampling cylinder 3 to move in the borehole, and moving the sampling cylinder 3 to the corresponding position in the borehole, and then driving the rotating support cylinder 12 to rotate between the two fixed support cylinders 11, adjusting the position of the sampling cylinder 17, so that the sampling cylinder 17 corresponds to one of the removal channels 4, and then driving the bent connector 16 to move in the sliding groove 15 through the screw transmission structure, so that the sampling cylinder 1 7 moves in the removal channel 4, the sampling cylinder 17 is removed from the sampling cylinder 3 through the removal channel 4, the sampling cylinder 17 gradually approaches the inner wall of the borehole, the second driving motor 20 is started to drive the spiral conveying rotating rod 19 and the rotating seat 18 to rotate, after the rotating seat 18 contacts the inner wall of the borehole, the special shape design of the rotating seat 18 can make the concave inner wall of the rotating seat 18 contact the inner wall of the borehole, as the concave inner wall of the rotating seat 18 gradually contacts the inner wall of the borehole, as the rotating seat 18 rotates, the ore powder rubbed off the inner wall of the borehole enters the sampling cylinder 17 through the entry groove, and the ore sample is driven to move under the action of the spiral conveying rotating rod 19, and finally enters the rotating support cylinder 12 through the conveying pipeline 21;

[0059] Then, the first drive motor 14 is started to drive the spiral conveying rod 13 to rotate, so that the ore sample moves in the fixed support cylinder 11 and the rotating support cylinder 12, and the ore sample is moved to the height corresponding to the sampling tube 5. The valve 27 on the corresponding discharge pipe 24 is opened, so that the ore sample enters the sampling tube 5 through the communication relationship between the discharge pipe 24 and the feed pipe 22. After sufficient ore samples are collected in the sampling tube 5, the third drive motor 31 is started to drive the winding cylinder 30 to rotate in the rotating frame 29, so that the traction rope 47 moves between the multiple fixed rings 33, so that the traction rope 47 moves the sampling tube 5 out of the placement cylinder 6, and moves the sampling tube 5 into the installation cylinder 1. Then, the detection personnel use a special container to move the container into the installation cylinder 1 through the removal port 35, and then open the valve 27 on the discharge pipe 26, tilt the sampling tube 5, so that the ore sample is moved out through the discharge port 28 on the discharge pipe 26, and the detection personnel continue to detect the ore sample later.

[0062] Step 2, moving the sampling cylinder 3: driving the rotating cylinder 8 to rotate in the fixed cylinder 7, through the threaded connection relationship between the threaded seat 9 and the splicing screw 2, and the sliding fit between the sliding member 10 and the sliding groove, the splicing screw 2 is moved longitudinally in the installation cylinder 1, driving the sampling cylinder 3 to move in the borehole, and moving the sampling cylinder 3 to the corresponding position in the borehole;

[0063] Step 3, adjusting the sampling cylinder 17: driving the rotating support cylinder 12 to rotate between the two fixed support cylinders 11 through the driving assembly, so that the sampling cylinder 17 moves along the center point of the rotating support cylinder 12 along with the rotating cylinder 8, so that the sampling cylinder 17 corresponds to one of the removal channels 4;

[0064] Step 4, moving the sampling cylinder 17: driving the bent connector 16 to move horizontally through the screw transmission structure, so that the bent connector 16 drives the sampling cylinder 17 into the removal channel 4, so that the sampling cylinder 17 finally opens the sealing cover 34, and the sampling cylinder 17 approaches the inner wall of the borehole;

[0065] Step 5, collecting ore samples: start the second driving motor 20 to drive the spiral conveying rotating rod 19 and the rotating seat 18 to rotate, and the concave inner wall of the rotating seat 18 gradually contacts the inner wall of the borehole. As the rotating seat 18 rotates, the ore powder rubbed off the inner wall of the borehole enters the sampling cylinder 17 through the entry groove, and the ore sample is driven to move under the action of the spiral conveying rotating rod 19, and finally enters the rotating support cylinder 12 through the conveying pipeline 21;

[0066] Step 6, conveying ore samples: start the first drive motor 14 to drive the spiral conveying rod 13 to rotate, so that the ore sample moves in the fixed support cylinder 11 and the rotating support cylinder 12, and moves the ore sample to a height corresponding to the sampling tube 5, and opens the valve 27 on the corresponding discharge pipe 24, so that the ore sample enters the sampling tube 5 through the communication relationship between the discharge pipe 24 and the feed pipe 22;

[0067] Step 7, removing the sampling tube 5: after sufficient ore samples are collected in the sampling tube 5, the third driving motor 31 is started to drive the winding cylinder 30 to rotate in the rotating frame 29, so that the traction rope 47 moves between the plurality of fixing rings 33, so that the traction rope 47 moves the sampling tube 5 out of the placing cylinder 6, and moves the sampling tube 5 into the installation cylinder 1;

[0068] Step 8, collecting ore samples: the inspector uses a special container to move the container into the installation cylinder 1 through the removal port 35, then opens the valve 27 on the discharge pipe 26, tilts the sampling tube 5, and allows the ore sample to be removed through the discharge port 28 on the discharge pipe 26.
