Description

Technical Field

[0001] The present invention relates to the technical field of construction of injection holes and exploration holes in ionic rare earth mines, and in particular to dual-function drilling equipment and a drilling method for ionic rare earth mines. Background Art

[0002] Before mining, ion-type rare earth mines typically conduct ore block exploration. Based on the exploration results, injection holes are optimally distributed within the blocks. Traditional drilling equipment often uses manual Luoyang shovels. Due to different drilling processes, injection holes are typically larger, ranging from 180 to 200 mm, while exploration holes are smaller, typically 100 mm. Therefore, two different Luoyang shovels are often required, a problem also encountered with electric Luoyang shovels. More importantly, drilling exploration and injection holes often relies on manual percussion with a rod to increase depth. Consequently, the depth of each hole is relatively shallow, requiring repeated lifting, clearing, and lowering of the rod. As the hole depth increases, the time spent lifting and clearing increases. According to actual tests at a site in Dingnan, drilling with a manual Luoyang shovel only accounts for one-third of the total drilling time, with the majority of the remaining time spent lifting and clearing. Therefore, manual percussion drilling with a Luoyang shovel is labor-intensive and inefficient.

[0003] Ionic rare earth mines contain scattered hard, semi-weathered rock blocks, making them difficult to break and penetrate with a manual Luoyang shovel. The current solution is to drill new holes near the affected area, which severely impacts prospecting accuracy and the proper placement of injection holes.

[0026] The driver 3 drives the key shaft 4 to realize the compound movement of simultaneous rotation and descent or rotation and ascent, which effectively increases the working distance of the key shaft 4; eliminates the traditional track-type lifting scheme, effectively improves the overall lightweight improvement, facilitates outdoor transportation, and improves the efficiency of outdoor drilling operations; the sampling container 6 provided in the sampling channel 45 effectively realizes layered sampling of soil at different depths and ensures the purity of the sample.

[0027] The outer wall surface of the key shaft 4 is respectively provided with a spiral groove 41 and at least one groove group, and each groove group is arranged at equal intervals along the circumference of the key shaft 4; the spiral groove 41 extends spirally along the outer wall surface of the key shaft 4 from one end of the key shaft 4 to the other end of the key shaft 4; the groove group includes two U-shaped grooves 42, and the two U-shaped grooves 42 extend from one end of the key shaft 4 to the other end of the key shaft 4, and the two U-shaped grooves 42 are arranged in sequence along the circumference of the key shaft 4; one of the output ends of the driver 3 is embedded in the spiral groove 41, and the other output end of the driver 3 is embedded in each U-shaped groove 42.

[0028] Specifically, the key shaft 4 is provided with three groove groups.

[0029] Specifically, the fixed bracket 1 is the main load-bearing structure. A handrail 12 is also provided on one side of the fixed bracket 1 where the controller 11 is provided. The handrail 12 facilitates the staff to keep the fixed bracket 1 in a vertical state. A pointed screw 13 is also provided at the bottom end of the fixed bracket 1. The pointed screw 13 is inserted into the soil to help the fixed bracket 1 be fixed vertically to the ground.

[0030] The driver 3 includes a servo motor 46, a rotating platform 31 and a rotating frame 32. The rotating platform 31 has a mounting hole along the vertical center position, and the rotating frame 32 is arranged along the edge of the mounting hole; the rotating frame 32 has a connecting hole along the vertical center position, and the inner wall surface of the connecting hole has a first slide groove and a second slide groove in sequence along the axial direction, and the first slide groove and the second slide groove are arranged at intervals along the vertical direction; the first slide groove extends circumferentially along the central axis of the connecting hole, and a plurality of first balls 33 are arranged in the first slide groove, and each first ball 33 is slidably connected to a U-shaped groove respectively; the second slide groove is arranged along the vertical spiral, and a second ball is arranged in the second slide groove, and the second ball is slidably connected to the spiral groove 41; the servo motor 46 drives the connecting rotating frame 32; the key shaft 4 is used to pass through the connecting hole so that each first ball 33 is slidably connected to the adjacent U-shaped groove 42, and each second ball is connected to the spiral groove 41.

[0031] Specifically, a worm gear structure is provided in the rotating platform 31 , and the servo motor 46 drives the rotating frame 32 to rotate via the worm gear structure. The worm gear structure is a common mechanical component and will not be described in detail here.

[0032] The servo motor 46 drives the rotating frame 32 to rotate through the worm gear structure. When the rotating frame 32 rotates, the first balls 33 in the first chute cooperate with the U-shaped groove of the key shaft 4 to drive the key shaft 4 to rotate, and the rotation provides driving force for the drilling mechanism to enable the drilling mechanism to crush the soil and drill holes; when the rotating frame 32 rotates, the second balls in the second chute cooperate with the spiral groove 41 of the key shaft 4 to drive the key shaft 4 to rise and fall, so that the key shaft 4 can simultaneously perform a compound motion of self-rotation and rise or self-rotation and descent.

[0033] Specifically, when the servo motor 46 drives the rotating frame 32 to rotate forward through the turbine worm structure, the key shaft 4 rotates and descends and drives the drilling mechanism to descend to perform drilling operations, and the sampling container 6 simultaneously performs soil sampling; when the servo motor 46 drives the rotating frame 32 to reverse through the turbine worm structure, the key shaft 4 rotates and rises and drives the drilling mechanism to rise away from the borehole.

[0034] The drilling mechanism 2 comprises a barrel 21 and a connecting frame 22. The barrel 21 is arranged vertically, with one end of the barrel 21 detachably connected to the key shaft 4 via the connecting frame 22. The end of the barrel 21, away from the key shaft 4, is open, and crushing teeth 23 are disposed at the open end of the barrel 21. A soil discharge port 27 is defined at the end of the barrel 21, near the connecting frame 22. A stopper tube 26 is also disposed within the barrel 21, away from the connecting frame 22. Both ends of the stopper tube 26 communicate with the interior of the barrel 21. The connecting frame 22 defines a sampling hole (not shown). A sampling container 6 is inserted into the barrel 21, passes through the sampling hole and the soil discharge port 27, and then abuts and connects to the stopper tube 26. As the crushing teeth 23 crush the soil, some soil is introduced into the barrel 21, where it is collected by the sampling container 6 through the stopper tube 26. Excess soil in the barrel 21 is discharged through the discharge port, preventing soil from clogging the barrel 21.

[0035] Specifically, a clamp 15 surrounding the cylinder 21 is further provided on one side of the fixing bracket 1 where the key shaft 4 is provided. The clamp 15 can play a limiting function.

[0036] Specifically, three connecting rods are sequentially provided in the circumference of the limiting tube 26 to connect the inner wall surface of the cylinder 21 .

[0037] A threaded column 43 is provided at the end of the key shaft 4 close to the drilling mechanism 2, and a first connecting screw hole 44 is provided at the end of the key shaft 4 away from the drilling mechanism 2; a second connecting screw hole is provided at the end of the connecting frame 22 away from the barrel 21, and the key shaft 4 is detachably connected to the second connecting screw hole via the threaded column 43; the second connecting screw hole is connected to the sampling through hole, and the sampling through hole is located at the end of the second connecting screw hole away from the key shaft 4; one end of the sampling channel 45 passes through the threaded column 43, and the other end of the sampling channel 45 is connected to the first connecting screw hole 44. When a longer insertion operation is required, the next key shaft 4 can be connected to the end of the key shaft 4 away from the drilling mechanism. The threaded column 43 of the key shaft 4 away from the drilling mechanism of the two adjacent key shafts 4 is threadedly connected to the first connecting screw hole 44 of the key shaft 4 close to the drilling mechanism, and they are connected in sequence until an injection hole that meets the process requirements is produced.

[0038] During the operation of the key shaft 4, neither the fixed platform 14 nor the mounting base needs to move up or down. As the drilling depth increases, only a new key shaft 4 needs to be added. During operation, the servo motor 46 and the rotating frame 32 remain relatively fixed in space and do not shift, thus maximizing the vertical displacement space.

[0039] Specifically, the aperture of the first connecting screw hole 44 is larger than the aperture of the sampling channel 45 .

[0040] Specifically, the sampling container 6 includes a first pipe 61 and at least one second pipe 62. The first pipe 61 is inserted into the sampling channel 45 of the key shaft 4 closest to the drilling mechanism 2, so that one end of the first pipe 61 is connected to the limiting tube 26, and the other end of the first pipe 61 extends into the first connecting screw hole 44; the second pipes 62 are arranged in the remaining key shafts 4 that are connected to the key shaft 4 closest to the drilling mechanism 2 in sequence. Due to the protrusion of the first pipe 61, each second pipe 62 will extend out of the first connecting screw hole 44 of the key shaft 4 in sequence, and be inserted into the sampling channel 45 of the key shaft 4 away from the drilling mechanism 2, so that the second pipes 62 in the key shaft 4 farthest from the drilling mechanism 2 are all extended to the outside, making it convenient for the staff to separate the second pipe 62 and the key shaft 4.

[0041] Specifically, a plug is provided at one end of the first pipe 61 near the limiting pipe 26. The plug is used to insert into the limiting pipe 26 so that the limiting pipe 26 abuts the end of the plug provided on the first pipe 61. A first latch hole is provided at the end of the first pipe 61 and the second pipe 62 away from the drilling mechanism 2, and a second latch hole is provided at the end of the key shaft 4 away from the drilling mechanism 2. After the staff inserts the first pipe 61 or the second pipe 62 into the sampling channel 45, the quick pin passes through the second latch hole and the first latch hole in sequence to fix the first pipe body or the second pipe body. The limiting pipe 26 and the quick pin fix the position of the sampling container 6 to prevent the sampling container 6 from being ejected during the sampling process.

[0042] A first connecting groove 24 is provided on the outer wall surface of the cylinder 21 along the axial direction, and two first positioning holes 25 are provided in the first connecting groove 24. The first connecting groove 24 is provided near the end of the cylinder 21 adjacent to the connecting frame 22; a soil collector 5 is provided at the end of the cylinder 21 away from the crushing teeth 23, and the end of the soil collector 5 close to the cylinder 21 is open. Two positioning blocks 53 are provided in the soil collector 5, and the two positioning blocks 53 are located at the end of the soil collector 5 close to the cylinder 21. One of the positioning blocks 53 is inserted into one of the first positioning holes 25, and the other positioning block 53 is inserted into the other first positioning hole 25.

[0043] A first connecting groove 24 and two first positioning holes 25 are provided at one end of the cylinder 21 away from the crushing teeth 23. The soil collector 5 is inserted into the two first positioning holes 25 through the two positioning holes so that the cylinder 21 and the soil collector 5 are tightly connected. As the drilling depth increases, when the soil inside the cylinder 21 is filled, the soil will enter the soil collector 5 through the discharge port 27.

[0044] A protective sleeve is provided at the end of the soil collector 5 away from the cylinder 21, and the protective sleeve is provided around and in contact with the connection between the connecting frame 22 and the key shaft 4; a second connecting groove 58 is provided axially on the outer wall surface of the soil collector 5, and two second positioning holes 59 are provided in the second connecting groove 58. The provision of the protective sleeve can prevent soil from invading the connection between the drilling mechanism and the key shaft 4. The structure of the soil collector 5 is similar to that of an extension rod. The staff can install another soil collector 5 at the end of the soil collector 5 away from the cylinder 21 according to the drilling depth, so that the two positioning blocks 53 of the soil collector 5 of the two adjacent soil collectors 5 away from the cylinder 21 are respectively inserted into the two second positioning holes 59 of the soil collector 5 close to the cylinder 21. In this way, there is no need for repeated lifting and lowering. After the predetermined depth is reached, the drilling mechanism 2 is moved out of the hole, eliminating the repeated lifting and lowering process and improving the efficiency of the shift.

[0045] The soil collector 5 includes a left shell 51 and a right shell 52 axially symmetrically arranged along the key shaft 4, wherein a positioning block 53 is arranged on the side of the left shell 51 facing the right shell 52, and the positioning block 53 arranged on the left shell 51 is located at the end of the left shell 51 close to the cylinder 21; the other positioning blocks 53 are all arranged on the side of the right shell 52 facing the left shell 51, and the positioning block 53 arranged on the right shell 52 is located at the end of the right shell 52 close to the cylinder 21.

[0046] Specifically, the protective cover includes a left half tube 54 and a right plate tube 55. The left half tube 54 is arranged on the side of the left shell 51 facing the right shell 52, and the left half tube 54 is arranged away from the cylinder 21; the right half tube is arranged on the side of the right shell 52 facing the left shell 51, and the right half tube is arranged away from the cylinder 21.

[0047] The housing is provided with two first fixing holes 56, and the right housing 52 is provided with two second fixing holes 57. One first fixing hole 56 and one of the second fixing holes 57 are coaxially connected and arranged in communication, while the other first fixing hole 56 and the other second fixing hole 57 are coaxially connected and arranged in communication. The axial directions of the two first fixing holes 56 and the axial directions of the two second fixing vents are perpendicular to the axial direction of the key shaft 4. The left housing 51 and the right housing 52 are fixed by two sets of bolts and nuts. One set of bolts and nuts passes through one of the first fixing holes 56 and one of the second fixing holes 57, and the other set of bolts and nuts passes through the other first fixing hole 56 and the other second fixing hole 57. The two sets of bolts and nuts can be quickly disassembled by the staff using a rechargeable handheld electric drill.
