Description

A hole-reaming device for solid mineral exploration and its usage method Technical Field

[0001] This invention relates to the field of mineral exploration technology, specifically to a hole-reaming device for solid mineral exploration and its usage method. Background Technology

[0002] Solid minerals include coal, coal shale, and metallic minerals. In solid mineral exploration, drilling equipment is frequently used to drill holes to investigate the distribution of minerals in the area. Sometimes, a smaller diameter drill rod is used first to drill the hole, and then a larger diameter drill rod is used to re-drill the hole, enlarging the previously drilled hole and gradually creating a larger diameter borehole for more detailed mineral exploration. However, current solid mineral exploration borehole enlarging equipment typically involves removing the original smaller diameter drill rod after drilling and then installing the larger diameter drill rod. This requires multiple enlarging operations, or when exploring multiple locations, it takes a considerable amount of time and effort to repeatedly disassemble and reassemble the drill rod, hindering rapid exploration. Summary of the Invention

[0003] To overcome the aforementioned technical problems, the present invention aims to provide a solid mineral exploration borehole enlargement device and its usage method. By having the inside of the lifting block contact the side of the insertion block, when a larger diameter drill rod is needed for borehole enlargement, the drill rod can rotate towards the lifting block, causing the insertion block on the connecting seat to move into the lifting block. At this time, the lifting block can drive the larger diameter drill rod downwards to enlarge the borehole. During borehole enlargement, multiple drill rods can be moved sequentially to the drilling position for enlargement, eliminating the need for frequent disassembly and installation of drill rods, thus facilitating rapid exploration.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A solid mineral exploration borehole enlargement device includes a support module and an adjustment module. The support module includes a support plate, a fixed frame fixedly connected to the top surface of the support plate, a lifting screw rotatably connected to the inner side of the fixed frame, a lifting block slidably connected to the inner side of the fixed frame and screwed to the side of the lifting screw, a drive motor is provided at the top of the inner side of the fixed frame, and the output power of the drive motor is transmittedly connected to the top of the lifting screw. The adjustment module includes a fixed plate, four connecting seats are provided on the side of the fixed plate, plug-in blocks are fixedly connected to the side of the connecting seats, the inside of the lifting block contacts the side of the adjacent plug-in block, a fixed seat is rotatably connected to the bottom surface of the connecting seats, a drill rod is provided at the bottom of the fixed seat, a connecting cylinder rotatably connected to the bottom surface of the fixed seat and rotatably connected to the inner side of the connecting seat, a gear is fixedly sleeved on the side of the connecting cylinder, a power mechanism is provided on the top surface of the lifting block, a limiting rod slidably connected to the top surface of the fixed plate and fixedly connected to the side of the fixed seat, a limiting groove is opened on one side of the fixed plate located on the lifting block, and a limiting frame fixedly connected to the top surface of the support plate is fixedly connected to the inner side of the limiting groove.

[0006] The lifting screw can be rotated by a drive motor, causing the lifting block to move downwards along the screw. The lifting block can then move the adjacent connecting seat downwards via a plug-in block, causing the fixed seat and drill rod near the lifting block to move downwards. The limiting rod can move downwards through the limiting groove into the limiting frame, thus limiting the limiting rod and connecting seat and preventing them from tilting. The drill rod can be rotated by a power mechanism, causing it to drill downwards. After drilling is completed, the lifting block can be moved upwards to its original position, and then the connecting seat and drill rod can be moved to move the drill rod away from the lifting block. Move the drill rod and rotate it towards the lifting block, causing the insertion block on the next connecting seat to move into the lifting block. At this point, the lifting block can drive the drill rod with a larger diameter to move downward to enlarge the hole. This allows multiple drill rods with different diameters to be installed in the fixed seat in advance. When drilling for exploration, after drilling with a drill rod with a smaller diameter, the position of the drill rod can be directly adjusted so that multiple drill rods can be moved sequentially to the drilling position to enlarge the hole. When exploring multiple positions and each position requires multiple enlargements, there is no need to frequently disassemble and install the drill rod, which is conducive to the rapid progress of exploration.

[0007] Furthermore, the following features are provided: a fixing rod is fixedly connected to the bottom surface of the fixing plate and to the top surface of the support plate; a connecting frame is fixedly connected to the top surface of the support plate and to the fixing frame; a connecting box is fixedly connected to the bottom surface of the connecting frame at the top of the fixing plate; an adjusting motor is installed inside the connecting box; a rotating rod is rotatably connected to the top surface of the fixing plate at the output end of the adjusting motor; four T-shaped blocks are fixedly connected to the side of the rotating rod and slidably connected to the side of the adjacent limiting rod; a fixing frame is fixedly connected to the side of the connecting frame; and a contact point is fixedly connected to the bottom surface of the adjacent insertion block on the side of the fixing frame. The support ring and fixing rod can fix the position of the fixing plate. The support ring can support adjacent plug blocks. The lifting block can pass through the opening of the support ring. The connecting frame helps to increase the stability of the fixing frame. When it is necessary to adjust the position of the drill rod, the motor can be adjusted to drive the rotating rod to rotate. The rotating rod can be turned by the T-block to move the limit rod, so that the connecting seat can be rotated, thereby adjusting the position of the drill rod and causing the plug block on the next connecting seat to be inserted into the lifting block. The lifting block drives the next connecting seat to move downward through the plug block, so that the drill rod with a larger diameter can be adjusted to the drilling position for hole enlargement. No manual adjustment is required, which is convenient to use.

[0008] Furthermore, the fixed base has two connecting screws screwed to the top of the drill rod. The power mechanism includes a fixed box, the bottom of which is fixedly connected to the top of the lifting block. A power motor is installed inside the fixed box. The output end of the power motor is connected to a transmission rod that is rotatably connected to the inner side of the fixed box. A gear 1 is fixedly sleeved on the side of the transmission rod, and the gear 1 meshes with an adjacent gear 2. The drill rod can be fixed in the fixed base by the connecting screws. The power motor can drive the transmission rod and gear 1 to rotate. Gear 1 can drive the adjacent gear 2 to rotate. Gear 2 can drive the connecting cylinder and the fixed base to rotate. The fixed base can drive the drill rod to rotate by the connecting screws, thereby drilling a hole. When adjusting the position of the drill rod, gear 1 can disengage from the adjacent gear 2 and then mesh with the gear 2 on the top of the next connecting base.

[0009] Furthermore, a drill block is provided on the bottom side of the drill rod, and two connecting frames are fixedly connected to the top surface of the drill block. Connecting screws pass through the interior of adjacent connecting frames, and connecting blocks are fixedly connected to the top of the opposing surfaces of the two connecting frames. A threaded hole is provided on the top surface of each connecting block, and a positioning screw passing through the threaded hole is provided inside the drill block. When the drill rod moves downwards and rotates forward to drill, the fixed seat will drive the connecting frames to rotate via the connecting screws, causing the drill block and connecting blocks to rotate forward. While the connecting blocks rotate forward, the threaded hole inside the connecting block remains disengaged from the positioning screw, thus preventing the connecting block from moving downwards along the positioning screw, while the connecting frames remain aligned with the positioning screw. The rod passes through the inside of the connecting cylinder. After drilling is completed, the transmission rod can be rotated in the opposite direction by the power motor. This causes the fixed seat to rotate in the opposite direction via the connecting screws, along with the drill rod, connecting frame, and connecting block. Since the threaded hole contacts the top of the thread on the positioning screw, the threaded hole will engage with the thread on the positioning screw. This causes the connecting block to rotate and move downwards along the positioning screw, which in turn causes the connecting block to move downwards and rotate, and the drill block to move downwards and rotate. This process initially enlarges the drilled exploration hole, which helps reduce the difficulty of enlarging the hole with a larger diameter drill rod in the future. It also helps reduce the difficulty of each enlargement operation and facilitates the smooth progress of the enlargement process.

[0010] Furthermore, the connecting cylinder is equipped with a positioning rod inside, and an adjusting frame is fixedly connected to the side of the rotating rod. The sides of the four positioning rods are all fixedly connected to the sides of the adjusting frame. A rectangular block that slides into the positioning rod is fixedly connected to the top of the positioning screw. A positioning screw that screws into the rectangular block is screwed onto the inner side of the positioning rod. The rotating rod will limit the position of the positioning rod through the adjusting frame, and the positioning rod will limit the rotation of the positioning screw through the rectangular block and limit the height of the positioning screw through the positioning screw. This allows the connecting block to move downward along the positioning screw when it rotates, and the rotating rod can adjust the position of the positioning rod and the positioning screw through the adjusting frame.

[0011] Furthermore, a rotating frame is rotatably connected to the top surface of the support plate away from the fixed frame. Several plug-in seats are slidably connected to the inner side of the rotating frame. Several drill rods of different diameters can be set in the plug-in seats as backups. The connecting screw can be rotated to disengage the drill rod and the connecting frame from the connecting screw. At the same time, the positioning screw can be rotated to disengage the positioning screw from the rectangular block. In this way, the drill rod can be moved downward and removed from the fixed seat. Then, the drill rod of the appropriate diameter can be replaced according to the needs of drilling and reaming.

[0012] Furthermore, the inner bottom surface of the rotating frame has several insertion slots corresponding to several insertion seats. A connecting screw rod passing through adjacent insertion slots is screwed onto the inner side of the support plate. A rotating shaft is rotatably connected to the inner side of the support plate. Two sliding blocks are fixedly connected to the inner side of the rotating shaft. A sliding groove is provided on the side of the connecting screw rod that slidably connects with the adjacent sliding blocks. An adjusting rod is rotatably connected to one side of the inner side of the support plate. Pulleys are fixedly sleeved on both the side of the adjusting rod and the side of the rotating shaft. The two pulleys are connected by belt drive, allowing the adjusting rod to rotate. The adjusting rod can drive the rotating shaft to rotate via the pulleys. The rotating shaft can drive the connecting screw rod to rotate via the sliding blocks. Since the support plate and the connecting screw rod are screwed together, the connecting screw rod can move up or down, allowing it to pass through adjacent insertion slots and lift the insertion seat at its top, or lower the insertion seat at the top of the connecting screw rod. This allows the insertion seat to catch the removed drill rod, or lift the drill rod so that it can be inserted into the fixed seat, facilitating drill rod installation.

[0013] Furthermore, a support frame is fixedly connected to the side of the connecting frame corresponding to the rotating frame, and an arc-shaped rod is rotatably connected to the inner side of the support frame. The support frame and the arc-shaped rod can block the side of the drill rod, and the arc-shaped rod can be retracted into the support frame to avoid blocking the rotation of the drill rod installed in the fixed seat.

[0014] A method for using a borehole enlargement device for solid mineral exploration, the specific operating steps of which are as follows:

[0015] Step 1: The lifting screw is rotated by the drive motor, which causes the lifting block to move downward through the plug block and the adjacent connecting seat, thus moving the drill rod downward. At the same time, the transmission rod is rotated in the forward direction by the power motor, which causes the fixed seat to rotate through the connecting screw, thereby moving the drill rod downward and rotating to drill a hole in the ground.

[0016] Step 2: After the initial drilling of the drill rod is completed, the transmission rod is driven to rotate in the opposite direction by the power motor, which causes the connecting block to rotate in the opposite direction. This causes the threaded hole in the connecting block to engage with the thread on the positioning screw, thereby causing the connecting block to move and rotate downward along the positioning screw, which in turn causes the drill block to move and rotate downward to perform preliminary enlargement of the drilled exploration hole.

[0017] Step 3: After the initial hole enlargement is completed, start the drive motor to make the lifting screw rotate in the reverse direction, so that the lifting block drives the connecting seat to move upward through the plug block, and the drill rod moves upward. At the same time, the power motor drives the transmission rod to rotate in the forward direction, thereby moving the drill rod, drill block, etc. upward to their original positions.

[0018] Step 4: By adjusting the motor to drive the rotating rod to rotate, the rotating rod will rotate through the T-block to move the limit rod, adjust the position of the connecting seat, so that the plug block on the next connecting seat is inserted into the lifting block, and rotate the next larger diameter drill rod to the exploration position. Then, by using the drive motor and the power motor, the next larger diameter drill rod is moved downward and rotated, so that the next drill rod enlarges the drilled hole. Then, the positions of the drill rods are adjusted in sequence, so that the other drill rods enlarge the exploration hole in sequence.

[0019] The beneficial effects of this invention are:

[0020] 1. By contacting the inside of the lifting block with the side of the insertion block, the lifting screw can be rotated by the drive motor, causing the lifting block to move the insertion block downwards, thereby causing the connecting seat to move the drill rod downwards. At the same time, the power mechanism can rotate the drill rod, causing the drill rod to drill downwards. After one drilling is completed, the lifting block is moved back to its original position, and the next connecting seat and the drill rod with a larger bottom diameter can rotate towards the lifting block, causing the insertion block on the next connecting seat to move into the lifting block. At this time, the lifting block can drive the drill rod with a larger diameter to move downwards to enlarge the hole. In this way, multiple drill rods with different diameters can be pre-installed in the corresponding fixed seats. When enlarging the hole, multiple drill rods can be moved to the drilling position in sequence to enlarge the hole. When multiple locations are explored and each location needs to be enlarged multiple times, it is not necessary to frequently disassemble and install the drill rod, which is conducive to the rapid exploration.

[0021] 2. By passing the connecting screw through the interior of the adjacent connecting frame, the fixing seat can drive the drill rod and the connecting frame to rotate through the connecting screw. When the fixing seat drives the drill rod to rotate in the forward direction, the threaded hole in the connecting block will disengage from the thread on the positioning screw. At this time, only the drill rod will move downward to drill. After one drilling is completed, the fixing seat can drive the drill rod and the connecting frame to rotate in the opposite direction through the screw. At this time, the threaded hole in the connecting block will engage with the thread on the positioning screw, causing the drill block to move downward and rotate, thereby initially enlarging the hole drilled by the drill rod. This helps to reduce the difficulty of enlarging the hole with a larger diameter drill rod in the future, reduces the difficulty of each enlarging operation, and facilitates the smooth progress of enlarging.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0039] Please refer to Figures 1-14. A solid mineral exploration borehole enlargement device includes a support module 100 and an adjustment module 200. The support module 100 includes a support plate 110, a fixed frame 120 fixedly connected to the top surface of the support plate 110, a lifting screw 121 rotatably connected to the inner side of the fixed frame 120, a lifting block 122 slidably connected to the inner side of the fixed frame 120 and screwed to the side of the lifting screw 121, and a drive motor 123 is provided at the top of the inner side of the fixed frame 120. The output power of the drive motor 123 is transmitted to the top of the lifting screw 121. The adjustment module 200 includes a fixed plate 210, four connecting seats 230 are provided on the side of the fixed plate 210, and the connecting seats 230 are fixedly connected to the side of the fixed plate 210. The lifting block 122 is connected to the plug-in block 232. The inside of the lifting block 122 is in contact with the side of the adjacent plug-in block 232. The bottom surface of the connecting seat 230 is rotatably connected to the fixed seat 240. The bottom of the fixed seat 240 is provided with a drill rod 300. The bottom surface of the fixed seat 240 is rotatably connected to the connecting cylinder 242, which is rotatably connected to the inner side of the connecting seat 230. The side of the connecting cylinder 242 is fixedly sleeved with a gear 243. The top surface of the lifting block 122 is provided with a power mechanism 150. The side of the fixed seat 240 is fixedly connected to a limiting rod 231 that is slidably connected to the top surface of the fixed plate 210. The fixed plate 210 is located on one side of the lifting block 122 and has a limiting groove. The inner side of the limiting groove is fixedly connected to a limiting frame 212 that is fixedly connected to the top surface of the support plate 110.

[0040] The lifting screw 121 can be rotated by the drive motor 123, causing the lifting block 122 to move downward along the lifting screw 121. The lifting block 122 can drive the adjacent connecting seat 230 to move downward through the plug-in block 232, causing the fixed seat 240 and drill rod 300 near the lifting block 122 to move downward. The limiting rod 231 can move downward through the limiting groove into the limiting frame 212. In this way, the limiting frame 212 can limit the limiting rod 231 and the connecting seat 230, preventing the connecting seat 230 from tilting. The drill rod 300 can be rotated by the power mechanism 150, causing the drill rod 300 to drill downward. After one drilling is completed, the lifting block 122 can be moved upward to its original position, and then the connecting seat 230 and drill rod 300 can be moved. The original drill rod 300 is moved away from the lifting block 122, and the next drill rod 300 with a larger diameter is rotated toward the lifting block 122, so that the insertion block 232 on the next connecting seat 230 moves into the lifting block 122. At this time, the lifting block 122 can drive the drill rod 300 with a larger diameter to move downward to enlarge the hole. In this way, multiple drill rods 300 with different diameters can be installed in the fixed seat 240 in advance. When drilling for exploration, after drilling with a drill rod 300 with a smaller diameter, the position of the drill rod 300 can be directly adjusted so that multiple drill rods 300 can be moved to the drilling position in sequence to enlarge the hole. When exploration is carried out at multiple positions and each position requires multiple enlargements, it is not necessary to frequently disassemble and install the drill rod 300, which is conducive to the rapid progress of exploration.

[0041] A fixing rod 211 is fixedly connected to the bottom surface of the fixing plate 210 and to the top surface of the support plate 110. A connecting frame 130 is fixedly connected to the top surface of the support plate 110 and to the fixing frame 120. A connecting box 220 is fixedly connected to the bottom surface of the connecting frame 130 at the top of the fixing plate 210. An adjusting motor is installed inside the connecting box 220. A rotating rod 221 is rotatably connected to the top surface of the fixing plate 210 at the output end of the adjusting motor. Four T-blocks 222 are fixedly connected to the side of the rotating rod 221 and slidably connected to the side of the adjacent limiting rod 231. A fixing frame 131 is fixedly connected to the side of the connecting frame 130. A support ring 132 that contacts the bottom surface of the adjacent plug-in block 232 is fixedly connected to the side of the fixing frame 131. The fixing rod 211 can... The fixed plate 210 is fixed in position, the support ring 132 can support the adjacent plug-in block 232, the lifting block 122 can pass through the opening of the support ring 132, and the connecting frame 130 helps to increase the stability of the fixed frame 120. When it is necessary to adjust the position of the drill rod 300, the rotating rod 221 can be rotated by adjusting the motor. The rotating rod 221 can be turned by the T-block 222 to move the limiting rod 231, so that the connecting seat 230 can be rotated, thereby adjusting the position of the drill rod 300 and causing the plug-in block 232 on the next connecting seat 230 to be inserted into the lifting block 122. The lifting block 122 drives the next connecting seat 230 to move downward through the plug-in block 232, so that the drill rod 300 with a larger diameter can be adjusted to the drilling position for hole enlargement. No manual adjustment is required, which is convenient to use.

[0042] The mounting base 240 has two connecting screws 241 that are screwed onto the top of the drill rod 300. The power mechanism 150 includes a mounting box 154, the bottom of which is fixedly connected to the top of the lifting block 122. A power motor 151 is installed inside the mounting box 154. The output end of the power motor 151 is connected to a transmission rod 152 that is rotatably connected to the inner side of the mounting box 154. A gear 153 is fixedly sleeved on the side of the transmission rod 152, and the gear 153 meshes with an adjacent gear 243. The drill rod 300 can be fixed inside the mounting base 240 by the connecting screws 241. The transmission rod 152 and gear 153 can rotate. Gear 153 can drive the adjacent gear 243 to rotate. Gear 243 can drive the connecting cylinder 242 and the fixed seat 240 to rotate. The fixed seat 240 can drive the drill rod 300 to rotate through the connecting screw 241, so that the drill rod 300 drills a hole. When adjusting the position of the drill rod 300, gear 153 can disengage from the adjacent gear 243 and then mesh with gear 243 on the top of the next connecting seat 230. A fixed cover that is rotatably connected to the connecting cylinder 242 can be fixedly installed on the top of the connecting seat 230 to block gear 243.

[0043] A drill block 310 is provided on the bottom side of the drill rod 300. Two connecting frames 311 are fixedly connected to the top surface of the drill block 310. Connecting screws 241 pass through the interior of adjacent connecting frames 311. A connecting block 320 is fixedly connected to the top of the opposite surfaces of the two connecting frames 311. A threaded hole is opened on the top surface of the connecting block 320. A positioning screw 330 passing through the threaded hole is provided inside the drill block 310. When the drill rod 300 moves downward and rotates forward to drill, the fixing seat 240 will drive the connecting frames 311 to rotate through the connecting screws 241, so that the drill block 310 and the connecting block 320 rotate forward. When the connecting block 320 rotates forward, the threaded hole inside the connecting block 320 remains disengaged from the positioning screw 330. In this way, the connecting block 320 will not move downward along the positioning screw 330, while the connecting frame 311 remains disengaged from the positioning screw 330. Rod 330 passes through the inside of connecting cylinder 242. After drilling is completed, the transmission rod 152 can be rotated in the opposite direction by the power motor 151, so that the fixed seat 240 drives the drill rod 300, connecting frame 311 and connecting block 320 to rotate in the opposite direction through connecting screw 241. Since the threaded hole is in contact with the top of the thread of the positioning screw 330, the threaded hole will be screwed into the thread on the positioning screw 330, so that the connecting block 320 rotates and moves downward along the positioning screw 330, thereby causing the connecting block 320 to drive the connecting frame 311 to move downward and rotate, and causing the drill block 310 to move downward and rotate, thereby performing preliminary hole enlargement on the drilled exploration hole. This helps to reduce the difficulty of enlarging the drill rod 300 with a larger diameter in the later stage, reduces the difficulty of each hole enlargement operation, and facilitates the smooth progress of hole enlargement.

[0044] The connecting cylinder 242 is equipped with a positioning rod 250. The rotating rod 221 is fixedly connected to the side of an adjusting frame 223. The sides of the four positioning rods 250 are all fixedly connected to the sides of the adjusting frame 223. The top of the positioning screw 330 is fixedly connected to a rectangular block 331 that slides into the interior of the positioning rod 250. The inner side of the positioning rod 250 is screwed with a positioning screw 251 that screws into the interior of the rectangular block 331. The rotating rod 221 restricts the position of the positioning rod 250 through the adjusting frame 223. The positioning rod 250 restricts the rotation of the positioning screw 330 through the rectangular block 331 and restricts the height of the positioning screw 330 through the positioning screw 251. When the connecting block 320 rotates, it can move downward along the positioning screw 330. The rotating rod 221 can adjust the position of the positioning rod 250 and the positioning screw 330 through the adjusting frame 223.

[0045] A rotating frame 140 is rotatably connected to the top surface of the support plate 110 away from the fixed frame 120. Several plug-in seats 141 are slidably connected to the inner side of the rotating frame 140. Several drill rods 300 of different diameters can be set in the plug-in seats 141 as backups. The connecting screw 241 can be rotated to disengage the drill rod 300 and the connecting frame 311 from the connecting screw 241. At the same time, the positioning screw 251 can be rotated to disengage the positioning screw 251 from the rectangular block 331. In this way, the drill rod 300 can be moved downward and removed from the fixed seat 240. Then, the drill rod 300 of the corresponding diameter can be replaced according to the needs of drilling and reaming.

[0046] The inner bottom surface of the rotating frame 140 has several insertion slots corresponding to several insertion seats 141. A connecting screw 112, passing through adjacent insertion slots, is screwed onto the inner side of the support plate 110. A rotating shaft 113 is rotatably connected to the inner side of the support plate 110. Two sliding blocks 115 are fixedly connected to the inner side of the rotating shaft 113. A sliding groove 114, which slidably connects to adjacent sliding blocks 115, is opened on the side of the connecting screw 112. An adjusting rod 111 is rotatably connected to one side of the inner side of the support plate 110. Pulleys 116 are fixedly sleeved on both the side of the adjusting rod 111 and the side of the rotating shaft 113, and the two pulleys 116 are connected by a belt drive, allowing rotation. The adjustable rod 111 can drive the rotating shaft 113 to rotate via the pulley 116. The rotating shaft 113 can drive the connecting screw 112 to rotate via the sliding block 115. Since the support plate 110 is screwed into the connecting screw 112, the connecting screw 112 can move up or down, so that the connecting screw 112 passes through the adjacent insertion slot and lifts the insertion seat 141 at its top, or lowers the insertion seat 141 at the top of the connecting screw 112. In this way, the removed drill rod 300 can be caught by the insertion seat 141, or the drill rod 300 can be lifted up and inserted into the fixed seat 240, which is convenient for the installation of the drill rod 300.

[0047] A support frame 160 is fixedly connected to the side of the connecting frame 130 corresponding to the rotating frame 140. An arc-shaped rod 161 is rotatably connected to the inner side of the support frame 160. The support frame 160 and the arc-shaped rod 161 can block the side of the drill rod 300. The arc-shaped rod 161 can be retracted into the support frame 160 to avoid blocking the rotation of the drill rod 300 installed in the fixed seat 240.

[0048] A method for using a borehole enlargement device for solid mineral exploration, the specific operating steps of which are as follows:

[0049] Step 1: Drive motor 123 to rotate lifting screw 121, causing lifting block 122 to move downward through plug block 232, driving adjacent connecting seat 230 to move downward, driving drill rod 300 to move downward. At the same time, drive motor 151 to rotate transmission rod 152 in the forward direction, causing fixed seat 240 to rotate through connecting screw 241, thereby causing drill rod 300 to move downward and rotate to drill a hole in the ground.

[0050] Step 2: After the initial drilling of the drill rod 300 is completed, the transmission rod 152 is driven to rotate in the opposite direction by the power motor 151, causing the connecting block 320 to rotate in the opposite direction. This causes the threaded hole in the connecting block 320 to engage with the thread on the positioning screw 330, thereby causing the connecting block 320 to move downward and rotate along the positioning screw 330, which in turn causes the drill block 310 to move downward and rotate to perform preliminary enlargement of the drilled exploration hole.

[0051] Step 3: After the initial hole enlargement is completed, start the drive motor 123 to make the lifting screw 121 rotate in the reverse direction, so that the lifting block 122 drives the connecting seat 230 to move upward through the plug block 232, so that the drill rod 300 moves upward. At the same time, the power motor 151 drives the transmission rod 152 to rotate in the forward direction, thereby moving the drill rod 300, drill block 310, etc. upward to their original positions.

[0052] Step 4: By adjusting the motor to drive the rotating rod 221 to rotate, the rotating rod 221 will move the limiting rod 231 to rotate through the T-block 222, adjusting the position of the connecting seat 230 so that the insertion block 232 on the next connecting seat 230 is inserted into the lifting block 122, and the next drill rod 300 with a larger diameter is rotated to the exploration position. Then, the drive motor 123 and the power motor 151 will move the next drill rod 300 with a larger diameter downward and rotate it, so that the next drill rod 300 will enlarge the drilled hole. Then, the positions of the drill rods 300 will be adjusted in sequence so that the other drill rods 300 will enlarge the exploration hole in sequence.

[0053] Working principle: In use, the drive motor 123 and the power motor 151 can be started. The drive motor 123 can drive the lifting screw 121 to rotate, causing the lifting block 122 to move downward along the lifting screw 121. The lifting block 122 can drive the power mechanism 150 to move downward. Furthermore, the lifting block 122 can drive the adjacent connecting seat 230 to move downward through the plug-in block 232, causing the fixed seat 240 and drill rod 300 near the lifting block 122 to move downward. The connecting seat 230 can drive the limit rod 231 to move downward, thus... The limiting rod 231 disengages from the adjacent T-block 222 and moves through the limiting groove into the limiting frame 212. The power motor 151 can drive the transmission rod 152 to rotate in the forward direction. The transmission rod 152 can drive the gear 153 to rotate. The gear 153 can drive the gear 243 meshing with it to rotate, so that the connecting cylinder 242 drives the fixed seat 240 to rotate. The fixed seat 240 can drive the drill rod 300 to rotate through the connecting screw 241, so that the drill rod 300 moves downward through the support plate 110 to drill a hole in the ground.

[0054] When the fixed base 240 rotates, the connecting frame 311 can be rotated by the connecting screw 241, so that the drill block 310 and the connecting block 320 rotate in the forward direction. When the connecting block 320 rotates in the forward direction, the threaded hole in the connecting block 320 will remain disengaged from the positioning screw 330. At the same time, since the positioning rod 250 fixes the position of the positioning screw 330 by the rectangular block 331 and the positioning screw 251, the connecting block 320 will not move downward along the positioning screw 330, so that the connecting frame 311 and the like pass through the inside of the connecting cylinder 242.

[0055] After the initial drilling by drill rod 300 is completed, drive motor 123 is stopped. Then, drive transmission rod 152 to rotate in the opposite direction via power motor 151. At this time, fixed seat 240 will drive drill rod 300 and connecting frame 311 to rotate in the opposite direction via connecting screw 241, causing connecting block 320 to rotate in the opposite direction. Due to gravity, threaded hole contacts the top of thread on positioning screw 330. Thus, when connecting block 320 rotates in the opposite direction, threaded hole will engage with thread on positioning screw 330, causing connecting block 320 to drive connecting frame 311 to move downward and rotate, causing drill block 310 to move downward and rotate, thereby drilling out the exploration hole. After the hole is initially enlarged, the drive motor 123 can be started to make the lifting screw 121 rotate in the reverse direction, so that the lifting block 122 drives the connecting seat 230 to move upward through the plug block 232, thereby making the fixed seat 240 and the drill rod 300 move upward. At the same time, the power motor 151 drives the transmission rod 152 to rotate in the forward direction, so that the connecting block 320 drives the connecting frame 311 and the drill block 310 to move upward, thereby moving the drill rod 300, the drill block 310, etc. upward to their original positions, so that the limiting rod 231 on the connecting seat 230 moves back to the top of the fixed plate 210 and plugs into the adjacent T-block 222.

[0056] An adjustable motor can be started, which can drive the rotating rod 221 to rotate. The rotating rod 221 can rotate the limiting rod 231 through the T-block 222, causing the connecting seat 230 to rotate. At the same time, the rotating rod 221 can drive the positioning rod 250 to rotate through the adjusting frame 223, thereby causing the next connecting seat 230 to move towards the lifting block 122, so that the insertion block 232 on the next connecting seat 230 is inserted into the lifting block 122, and the next drill rod 300 with a larger diameter rotates to the exploration hole position. The gear 243 on the next connecting seat 230 will mesh with the gear 153. Then, the next drill rod 300 with a larger diameter can be moved downward through the drive motor 123 and the power motor 151 to enlarge the drilled hole. Then, the position of the drill rods 300 is adjusted in sequence, so that the other drill rods 300 enlarge the exploration hole in sequence.

[0057] Several drill rods 300 of different diameters can be inserted into the corresponding insertion seats 141, which can cause the rotating frame 140 to rotate and move the drill rods 300 to the bottom of the fixed seat 240 away from the lifting block 122. At this time, the adjusting rod 111 can be rotated. The adjusting rod 111 can drive the rotating shaft 113 to rotate through the pulley 116. The rotating shaft 113 can drive the connecting screw 112 to move upward through the sliding block 115, so that the connecting screw 112 passes through the adjacent insertion slot and lifts the insertion seat 141 at its top. In this way, the adjacent drill rods 300 can be connected through the insertion seat 141. Then the drill rods 300 can be removed. Or, after the drill rods 300 are removed, the insertion seat 141 and the drill rods 300 inside can be lifted by the connecting screw 112, so that drill rods 300 of different diameters can be installed in the fixed seat 240.
