Description

Technical Field

[0001] This invention relates to the field of borehole expander technology, and more particularly to a borehole expander for geological exploration. Background Technology

[0002] A borehole reamer is a tool used in geological exploration for drilling operations. Its main function is to enlarge the diameter of the drilled hole. It is commonly used in geological exploration, mineral exploration, oil and gas exploration and other fields.

[0003] When using a reamer during base exploration, it is installed on the drill rod of the drilling rig. The operator moves the drill engine via a control frame, starts the engine, and moves the reamer along the drill rod through the hole in the ground. The reamer then begins to rotate, and its cutting edges contact the borehole wall. By rotating and cutting through the rock or soil, the diameter of the borehole is gradually increased. When the required diameter is reached, the drill rotation is stopped, completing the reaming operation. The reamer then separates from the drill rod. However, if the reamer cannot move stably downwards along the borehole during its downward movement, it can negatively impact the reaming effect. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art that when the reamer moves downward, it cannot move stably along the borehole, which affects the reaming effect. Therefore, this invention proposes a reamer for geological exploration.

[0005] To solve the above problems, the present invention adopts the following technical solution: a borehole reamer for geological exploration, comprising an engine, a control frame on one side of the engine, a drill rod on one side of the engine, a borehole reamer body on the side of the drill rod away from the engine, a stabilizing device on one side of the drill rod, the stabilizing device limiting and stabilizing the drill rod and the borehole reamer body, reinforcing components on both sides of the stabilizing device, the reinforcing components reinforcing the two sides of the stabilizing device with respect to the ground, a cooling component on one side of the stabilizing device, the cooling component cooling one side of the borehole reamer body, and a limiting component on one side of the cooling component, the limiting component limiting the operator's feet.

[0006] The effects achieved by the above components are as follows: When using the reamer body during the base exploration process, the reamer body is installed on the drill rod of the drilling rig. Then, the stabilizing device limits the angle between the drill rod and the reamer body, and the reinforcement component reinforces the stabilizing device on the ground. The operator moves the drilling rig's engine through the control frame and starts the engine, causing the reamer body on the drill rod to move through the hole on the ground. At this time, the cooling component cools the reamer body, and the limiting component limits the upper part of the operator's feet. Then, the reamer body begins to rotate, and the cutting edge of the reamer body begins to contact the wall of the borehole. By rotating and cutting the rock or soil, the diameter of the borehole is gradually enlarged. When the required diameter is reached, the rotation of the drilling rig is stopped, completing the reaming operation. Then, the reamer body separates from the drill rod.

[0007] Preferably, the stabilizing device includes a base plate with grooves on both sides. Sliding blocks are slidably disposed within the grooves on both sides of the base plate. A first connecting plate is provided on one side of each sliding block. A stabilizing block is provided on the side of the first connecting plate near the drill rod. A pedal is provided on the side of the first connecting plate away from the stabilizing block. A locking block is inserted into the side of the pedal. Several locking slots are provided on the side of the base plate near the locking block. A first spring is provided on the side of the locking block near the pedal, and the first spring is connected to the pedal. A toothed plate is provided on one side of each of the two stabilizing blocks. A first round rod is provided on the side of the base plate near the toothed plate. A gear is provided on one side of the first round rod, and the gear meshes with the toothed plate.

[0008] The effect achieved by the above components is as follows: Before using the reamer body, place the base plate at the drilling location, with the stabilizing blocks on both sides of the drilling hole. Then, the operator steps on the pedal and moves the pedal away from the drill rod. The first connecting plate on one side of the pedal will then move the stabilizing block fixed on one side away from the drilling hole. The sliding block fixed on one side of the first connecting plate will continue to slide inside the grooves on both sides of the base plate. When the stabilizing blocks move, they will move one side of the toothed plate. The toothed plate will then rotate with the gear. The first round rod fixed inside the toothed plate will rotate on one side of the base plate. The gear will then move the other side of the toothed plate, thus completing the separation of the two stabilizing blocks. Then, the drill rod will drive the reamer body through the base plate and into the drilling hole. The operator will then move the pedal, causing the pedal to move through the first connecting plate to bring the stabilizing block closer to the drill rod surface. The stabilizing block, via a toothed plate and gears, drives another stabilizing block closer to the drill rod. The operator then lowers their foot to insert a locking block on one side of the pedal into a slot on the side of the base plate. At this point, the first spring, fixed to the locking block and pedal, is compressed, fixing the position of the pedal, the first connecting plate, and the stabilizing block. This also limits the angle of the drill rod. After the reamer body is used, the operator lifts their foot, causing the first spring to return to its original position, disengaging the locking block from the slot on the base plate. The operator then uses their foot to move the pedal, moving the stabilizing block away from the drill rod, allowing the drill rod and reamer body to be removed from the ground. By using a stabilizing device, the angle of the drill rod can be limited, allowing the reamer body moving stably downwards along the drill hole to complete the reaming process, thus improving the effectiveness of the reamer body.

[0009] Preferably, a telescopic rod is sleeved inside the first spring, and the two ends of the telescopic rod are fixed to the locking block and the pedal to restrict the shape of the first spring.

[0010] The effect achieved by the above components is as follows: the telescopic rod is fitted inside the first spring, and the two ends of the telescopic rod are fixed to the locking block and the pedal respectively. Then, the telescopic rod restricts the shape of the first spring, preventing the first spring from bending and affecting the subsequent use of the first spring, thereby improving the use effect of the first spring.

[0011] Preferably, a baffle is provided on the side of the pedal away from the stabilizing block, and the baffle blocks the side of the pedal away from the stabilizing block.

[0012] The effect achieved by the above components is to block and limit the operator's foot on one side of the pedal by fixing a baffle on the side away from the stabilizing block, thereby improving the pedal's usability.

[0013] Preferably, one side of the pedal is provided with a plurality of anti-slip blocks, which increase the friction on one side of the pedal.

[0014] The effect achieved by the above components is to increase the friction between the pedal and the operator's foot by fixing several anti-slip blocks on one side of the pedal, thereby making it easier for the operator to move the pedal and improving the pedal's performance.

[0015] Preferably, the reinforcement assembly includes an extension plate, a second spring, a placement plate, a reinforcing nail, and a drive plate. The extension plate is disposed on both sides of the base plate, the two ends of the second spring are connected to the extension plate and the placement plate, the reinforcing nail is located on one side of the placement plate and penetrates the extension plate, and the drive plate is located on the side of the pedal near the placement plate.

[0016] The effect achieved by the above components is as follows: when the pedal is away from the drill rod, it will drive the drive plate fixed on one side to press the placement plate. Then, the placement plate will drive the reinforcing nail fixed on one side to slide inside the extension plates fixed on both sides of the base plate. Then, the reinforcing nail will be inserted into the ground. At this time, the second spring fixed to the extension plate and the placement plate will be compressed. Then, the reinforcing nail will reinforce the position of the base plate on the ground. Then, when the pedal is not used and the pedal drives the stabilizing block to move closer to each other, the second spring will return to its original position. Then, it will drive the placement plate and the reinforcing nail away from the ground, and then the reinforcing nail can be removed. By using the reinforcement component, the position of the base plate on the ground can be reinforced, so that the base plate is more stable on the ground for use.

[0017] Preferably, the cooling assembly includes a mounting block, bolts, a support frame, a water spray pipe, a hose, a water pump, and a square tube. The mounting block is disposed on one side of the base plate, and the bolts are inserted into the mounting block to fix the support frame. The support frame supports the water spray pipe and the hose. The square tube is disposed on the side of the water spray pipe near the stabilizing block, and the water pump is located on the side of the hose away from the water spray pipe.

[0018] The aforementioned components achieve the following effect: When using the reamer body, one side of the support frame is inserted into the mounting block fixed on the bottom plate. Then, the bolts are rotated to thread the bolts through the mounting block and the support frame. At this time, the support frame fixes the water spray pipe and supports one side of the hose. Then, the water pump side is connected to the drilling fluid container. The drilling fluid is then delivered to the hose connected on one side and sprayed out at the water spray pipe fixed on the hose side. The sprayed drilling fluid is blocked by the square tube fixed on the water spray pipe side and then reaches the borehole by gravity to cool the reamer body. By using the cooling component, the reamer body can be cooled during use, preventing overheating and damage or reduced working efficiency.

[0019] Preferably, an operating block is provided on one side of the bolt, and the operating block increases the dimension of one side of the bolt.

[0020] The effect achieved by the above components is to increase the contact area between the bolt and the operator by fixing the operating block on one side of the bolt, making it easier for the operator to rotate the bolt.

[0021] Preferably, the limiting assembly includes a second round rod, a driving plate, a control plate, a coil spring, a round block, a limiting plate, a fixing plate, a third spring, and a second connecting plate. The second round rod is disposed on one side of the support frame. The driving plate is disposed inside the second round rod near the water spray pipe. The control plate is disposed on the side of the second round rod away from the water spray pipe. The coil spring is fixed to the control frame and the round block on both sides. The limiting plate is disposed on one side of the fixing plate. The fixing plate is disposed on one side of the base plate. The two ends of the third spring are connected to the fixing plate and the second connecting plate. One side of the second connecting plate is connected to the limiting plate.

[0022] The effect achieved by the above components is as follows: When the water pump drives the drilling fluid through the spray pipe, the drive plate will be rotated, and then the second round rod fixed on one side of the drive plate will rotate inside the spray pipe and the support frame. Then, the coil spring fixed to the round block on the surface of the support frame and the second round rod will deform and limit the maximum angle of rotation of the drive plate. After the drive plate rotates the second round rod, the control plate fixed to the second round rod will press against the two limit plates, making the two limit plates close to the upper end of the pedal. Then, the two limit plates and the second connecting plate fixed on one side will slide on the side of the fixed plate fixed on one side of the base plate and be compressed by the third spring fixed to the fixed plate and the second connecting plate. Then, the two limit plates will limit the upper end of the operator's foot. After the hole expander finishes working and the cooling component is no longer used, the coil spring will drive the second round rod, drive plate and control plate to reset. Then, the third spring will drive the second connecting plate and limit plate to reset. By using the limit component, the upper end of the operator's foot can be limited, and the operator can better fix the position of the base plate.

[0023] Preferably, the limiting plate has an L-shaped cross-section, and the size of the protruding side of the limiting plate is adapted to the size of the pedal.

[0024] The effect achieved by the above components is as follows: by setting the limiting plate to an L-shape, and by bending the limiting plate so that the size of the protruding area matches the size of the pedal, the upper part of the operator's foot is better limited, thereby improving the effectiveness of the limiting plate.

[0025] In summary, the beneficial effects of the present invention are as follows:

[0026] In this invention, by using a stabilizing device, the angle of the drill rod can be limited, allowing the reamer body moving on the drill rod to move stably downwards along the drill hole and complete the reaming, thereby improving the performance of the reamer body.

[0027] In this invention, by using a reinforcement component, the position of the base plate on the ground can be reinforced, making the base plate more stable for use on the ground.

[0028] In this invention, by using a cooling component, the hole expander body can be cooled during use, thus preventing overheating and potential damage or reduced efficiency.

[0029] 1. In this invention, by using a limiting component, the upper part of the operator's feet can be limited, thereby enabling the operator to better fix the position of the base plate.

[0030] 2. In this invention, by using a cooling component, the hole expander body can be cooled during use, avoiding overheating of the hole expander body during use, which could lead to damage to the hole expander body or a decrease in working efficiency, and thus saving energy.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] Reference Figure 1-10As shown, this embodiment discloses a borehole reamer for geological exploration, including an engine 1, a control frame 2 on one side of the engine 1, a drill rod 3 on one side of the engine 1, a borehole reamer body 4 on the side of the drill rod 3 away from the engine 1, a stabilizing device 5 on one side of the drill rod 3, the stabilizing device 5 limiting and stabilizing the drill rod 3 and the borehole reamer body 4, reinforcement components 6 on both sides of the stabilizing device 5, the reinforcement components 6 reinforcing the two sides of the stabilizing device 5 with respect to the ground, a cooling component 7 on one side of the stabilizing device 5, the cooling component 7 cooling one side of the borehole reamer body 4, and a limiting component 8 on one side of the cooling component 7, the limiting component 8 limiting the operator's feet. When using the reamer body 4 during the base exploration process, the reamer body 4 is installed on the drill rod 3 of the drilling rig. Then, the stabilizing device 5 limits the angle between the drill rod 3 and the reamer body 4, and the reinforcing component 6 reinforces the stabilizing device 5 on the ground. The operator moves the engine 1 of the drilling rig through the control frame 2, and then starts the engine 1, so that the reamer body 4 on the drill rod 3 is moved in the hole on the ground. At this time, the cooling component 7 cools the reamer body 4, and the limiting component 8 limits the upper part of the operator's feet. Then, the reamer body 4 starts to rotate, and the cutting edge of the reamer body 4 begins to contact the wall of the borehole. By rotating and cutting the rock or soil, the diameter of the borehole is gradually enlarged. When the hole diameter reaches the requirement, the rotation of the drilling rig is stopped, the reaming operation is completed, and then the reamer body 4 is separated from the drill rod 3.

[0044] Reference Figure 1-10 As shown, this embodiment discloses a stabilizing device 5 including a base plate 51. Slide grooves 52 are provided on both sides of the base plate 51. Sliding blocks 53 are slidably disposed inside the slide grooves 52 on both sides of the base plate 51. A first connecting plate 54 is provided on one side of the sliding block 53. A stabilizing block 55 is provided on the side of the first connecting plate 54 near the drill rod 3. A pedal 56 is provided on the side of the first connecting plate 54 away from the stabilizing block 55. A locking block 57 is inserted into one side of the pedal 56. Several locking slots 58 are provided on the side of the base plate 51 near the locking block 57. A first spring 59 is provided on the side of the locking block 57 near the pedal 56. One side of the first spring 59 is connected to the pedal 56. A toothed plate 510 is provided on one side of each of the two stabilizing blocks 55. A first round rod 511 is provided on the side of the base plate 51 near the toothed plate 510. A gear 512 is provided on one side of the first round rod 511. The gear 512 meshes with the toothed plate 510.

[0045] Reference Figure 1-10As shown, this embodiment discloses that before using the reamer body 4, the base plate 51 is placed at the drilling location, with the stabilizing blocks 55 positioned on both sides of the drilling hole. The operator then steps on the pedal 56, moving the pedal 56 away from the drill rod 3. The first connecting plate 54 on one side of the pedal 56 then moves the stabilizing blocks 55 fixed on one side away from the drilling hole. The sliding block 53 fixed on one side of the first connecting plate 54 continues to slide within the grooves 52 on both sides of the base plate 51. When the stabilizing blocks 55 move, they move one side of the toothed plate 510, causing the toothed plate 510 to rotate with the gear 512. The first round rod 511 fixed inside the toothed plate 510 rotates on one side of the base plate 51, and the gear 512 moves the other side of the toothed plate 510. This completes the separation of the two stabilizing blocks 55. The drill rod 3 then drives the reamer body 4 through the base plate 51 to the inside of the drilling hole. The operator then moves the pedal 56, causing it to pass through the first connecting plate 54 and move the stabilizing blocks 55 closer to the surface of the drill rod 3. The next stabilizing block 55, via the toothed plate 510 and gear 512, drives the other stabilizing block 55 closer to the drill rod 3. Then, the operator lowers their foot to insert the locking block 57 on one side of the pedal 56 into the slot 58 on the side of the base plate 51. At this time, the first spring 59, which is fixed to the locking block 57 and the pedal 56, is compressed, thereby fixing the position of the pedal 56, the first connecting plate 54, and the stabilizing block 55. This also limits the angle of the stabilizing block 55 on the drill rod 3. After the reamer body 4 is used up... The rear end of the foot is lifted, and then the first spring 59 returns to its original position, causing the locking block 57 to disengage from the locking groove 58 on one side of the base plate 51. Then, the operator uses the foot to drive the pedal 56, which in turn drives the stabilizing block 55 away from the drill rod 3. The drill rod 3 and the reamer body 4 are then removed from the ground. By using the stabilizing device 5, the angle of the drill rod 3 can be limited, allowing the reamer body 4, which moves on the drill rod 3, to move stably downwards along the drill hole, thus completing the reaming and improving the performance of the driller body.

[0046] Reference Figure 1-10As shown, this embodiment discloses a telescopic rod 513 sleeved inside the first spring 59. The two ends of the telescopic rod 513 are fixed to the locking block 57 and the pedal 56 to restrict the shape of the first spring 59. By sleeved inside the first spring 59 and fixed to the locking block 57 and the pedal 56 respectively, the telescopic rod 513 restricts the shape of the first spring 59, preventing it from bending and affecting its subsequent use, thus improving its performance. A baffle 514 is provided on the side of the pedal 56 away from the stabilizing block 55, blocking the pedal 56 on that side. By fixing the baffle 514 on the side of the pedal 56 away from the stabilizing block 55, the operator's foot is blocked and limited on that side of the pedal 56, thereby improving its performance. Several anti-slip blocks 515 are provided on one side of the pedal 56, increasing the friction on that side. By fixing several anti-slip blocks 515 to one side of the pedal 56, the friction between the pedal 56 and the operator's foot is increased, making it easier for the operator to move the pedal 56, thereby improving the performance of the pedal 56.

[0047] Reference Figure 1-10 As shown, this embodiment discloses a reinforcement component 6 including an extension plate 61, a second spring 62, a placement plate 63, a reinforcement nail 64, and a drive plate 65. The extension plate 61 is disposed on both sides of the base plate 51. The two ends of the second spring 62 are connected to the extension plate 61 and the placement plate 63. The reinforcement nail 64 is located on one side of the placement plate 63 and penetrates the extension plate 61. The drive plate 65 is located on the side of the pedal 56 near the placement plate 63. When the pedal 56 moves away from the drill rod 3, it will cause the drive plate 65 fixed on one side to press against the placement plate 63. Then, the placement plate 63 will cause the reinforcing nail 64 fixed on one side to slide inside the extension plate 61 fixed on both sides of the base plate 51. Then, the reinforcing nail 64 will be inserted into the ground. At this time, the second spring 62 fixed to the extension plate 61 and the placement plate 63 will be compressed. Then, the reinforcing nail 64 will reinforce the position of the base plate 51 on the ground. Then, when the pedal 56 is not used, after the pedal 56 drives the stabilizing block 55 to move closer to each other, the second spring 62 will return to its original position. Then, it will drive the placement plate 63 and the reinforcing nail 64 away from the ground. Then, the reinforcing nail 64 can be removed. By using the reinforcing component 6, the position of the base plate 51 on the ground can be reinforced, so that the base plate 51 can be more stably placed on the ground for use.

[0048] Reference Figure 1-10As shown, this embodiment discloses a cooling assembly 7 including a mounting block 71, bolts 72, a support frame 73, a water spray pipe 74, a hose 75, a water pump 76, and a square tube 77. The mounting block 71 is disposed on one side of the base plate 51, and the bolts 72 are inserted into the mounting block 71 to fix the support frame 73. The support frame 73 supports the water spray pipe 74 and the hose 75. The square tube 77 is disposed on the side of the water spray pipe 74 near the stabilizing block 55, and the water pump 76 is located on the side of the hose 75 away from the water spray pipe 74. When using the reamer body 4, insert one side of the support frame 73 into the mounting block 71 fixed on one side of the base plate 51, and then rotate the bolt 72 to thread it through the mounting block 71 and fix it to the support frame 73. At this time, the support frame 73 fixes the water spray pipe 74 and supports one side of the hose 75. Then connect one side of the water pump 76 to the container of drilling fluid, and then deliver the drilling fluid to the hose 75 connected on one side. Then spray it out at the water spray pipe 74 fixed on one side of the hose 75. The sprayed drilling fluid is blocked by the square tube 77 fixed on one side of the water spray pipe 74, and then reaches the inside of the borehole by gravity to cool the reamer body 4. By using the cooling component 7, the reamer body 4 can be cooled during use to avoid overheating during use, which could lead to damage to the reamer body 4 or a decrease in working efficiency.

[0049] Reference Figure 1-10 As shown, this embodiment discloses an operating block 78 on one side of the bolt 72, which increases the dimension of one side of the bolt 72. By fixing the operating block 78 to one side of the bolt 72, the contact area between the bolt 72 and the operator is increased, making it easier for the operator to rotate the bolt 72.

[0050] Reference Figure 1-10As shown, this embodiment discloses a limiting component 8 including a second round rod 81, a driving plate 82, a control plate 83, a coil spring 84, a round block 85, a limiting plate 86, a fixing plate 87, a third spring 88, and a second connecting plate 89. The second round rod 81 is disposed on one side of the support frame 73. The driving plate 82 is disposed inside the second round rod 81 near the water spray pipe 74. The control plate 83 is disposed on the side of the second round rod 81 away from the water spray pipe 74. The coil spring 84 is fixed to the control frame 2 and the round block 85 on both sides. The limiting plate 86 is disposed on one side of the fixing plate 87. The fixing plate 87 is disposed on one side of the base plate 51. The two ends of the third spring 88 are connected to the fixing plate 87 and the second connecting plate 89. One side of the second connecting plate 89 is connected to the limiting plate 86. When the water pump 76 drives the drilling fluid through the spray pipe 74, the drive plate 82 will be rotated. Then, the second round rod 81 fixed to one side of the drive plate 82 will rotate inside the spray pipe 74 and the support frame 73. The coil spring 84, which is fixed to the round block 85 on the surface of the support frame 73 and the second round rod 81, will deform, limiting the maximum rotation angle of the drive plate 82. After the drive plate 82 rotates the second round rod 81, the control plate 83 fixed to the second round rod 81 will press against the two limit plates 86, causing the two limit plates 86 to approach the upper end of the pedal 56. Then, the two limit plates 86 and the control plate 83 fixed to one side... The fixed second connecting plate 89 slides on the side of the fixed plate 87 fixed on one side of the base plate 51 and is compressed by the third spring 88 fixed to the fixed plate 87 and the second connecting plate 89. Then, the two limiting plates 86 limit the upper part of the operator's foot. After the hole expander finishes working and the cooling component 7 is no longer used, the coil spring 84 drives the second round rod 81, the driving plate 82 and the control plate 83 to reset. Then, the third spring 88 drives the second connecting plate 89 and the limiting plate 86 to reset. By using the limiting component 8, the upper part of the operator's foot can be limited, so that the operator can better fix the position of the base plate 51.

[0051] Reference Figure 1-10 As shown, this embodiment discloses that the limiting plate 86 has an L-shaped cross-section, and the size of the protruding side of the limiting plate 86 is adapted to the size of the pedal 56. By setting the limiting plate 86 to an L-shape and making the size of the protruding area of ​​the limiting plate 86 adapted to the size of the pedal 56 after bending, the upper part of the operator's foot is better limited, thereby improving the use effect of the limiting plate 86.

[0052] Working principle: When using the reamer body 4 during the base survey, the reamer body 4 is installed onto the drill rod 3 of the drilling rig. Then, the base plate 51 is placed at the drilling site, with the stabilizing blocks 55 positioned on both sides of the drilling hole. The support frame 73 is inserted into the mounting block 71 fixed on one side of the base plate 51. The bolt 72 is then rotated to thread the bolt through the mounting block 71 and the support frame 73. The support frame 73 secures the water spray pipe 74 and supports one side of the hose 75. The operator then steps on the pedal 56, moving the pedal 56 away from the drill rod 3. The first connecting plate 54 on one side of the pedal 56 then moves the stabilizing block 55 fixed on one side away from the drilling hole. The sliding block 53 fixed on one side of the first connecting plate 54 then moves the stabilizing block 55 away from the drilling hole on both sides of the base plate 51. The slide continues to slide inside the groove 52. When the stabilizing block 55 moves, it will drive one side of the toothed plate 510 to move. Then, the toothed plate 510 will drive the gear 512 to rotate. Then, the first round rod 511 fixed inside the toothed plate 510 will rotate on one side of the base plate 51. Then, the gear 512 will drive the other side of the toothed plate 510 to move. Then, the two stabilizing blocks 55 will move away from each other. Then, the drill rod 3 will drive the reamer body 4 to penetrate the base plate 51 and reach the inside of the drill hole. Then, the operator will move the pedal 56, so that the pedal 56, through the first connecting plate 54, will drive the stabilizing block 55 closer to the surface of the drill rod 3. Then, one stabilizing block 55, through the toothed plate 510 and the gear 512, will drive the other stabilizing block 55 closer to the drill rod 3. Then, the operator... By pointing the heel of the foot downwards, the locking block 57 on one side of the pedal 56 is inserted into the locking groove 58 on one side of the base plate 51. At this time, the first spring 59, which is fixed to the locking block 57 and the pedal 56, is compressed. Then, the locking block 57 fixes the position of the pedal 56, the first connecting plate 54, and the stabilizing block 55, and the stabilizing block 55 limits the angle of the drill rod 3. When the pedal 56 moves away from the drill rod 3, it will drive the drive plate 65 fixed on one side to press against the placement plate 63. Then, the placement plate 63 will drive the reinforcing nail 64 fixed on one side to slide inside the extension plates 61 fixed on both sides of the base plate 51. Then, the reinforcing nail 64 is inserted into the ground. At this time, the second spring 62, which is fixed to the extension plate 61 and the placement plate 63, is compressed. Then, the reinforcing nail 64 presses against the base plate 51. The drilling rig is reinforced on the ground. The operator then moves the engine 1 of the drilling rig via the control frame 2 and starts the engine 1, causing the reamer body 4 on the drill rod 3 to move through the hole on the ground. At this time, one side of the water pump 76 is connected to the drilling fluid container, and the drilling fluid is delivered to the hose 75 connected to the other side. It is then sprayed out through a water spray pipe 74 fixed to one side of the hose 75. The sprayed drilling fluid is blocked by a square tube 77 fixed to one side of the water spray pipe 74, and then reaches the inside of the borehole by gravity to cool the reamer body 4. As the water pump 76 drives the drilling fluid through the water spray pipe 74, the drive plate 82 is rotated, which in turn drives the second round rod 81 fixed to one side of the plate 82.The spring 84, which is fixed to the circular block 85 on the surface of the second round rod 81 and rotates inside the water spray pipe 74 and the support frame 73, deforms and limits the maximum rotation angle of the driving plate 82. After the driving plate 82 rotates the second round rod 81, the control plate 83 fixed to the second round rod 81 will press against the two limiting plates 86, causing the two limiting plates 86 to approach the upper end of the pedal 56. Then, the two limiting plates 86 and the second connecting plate 89 fixed on one side will... The fixing plate 87, fixed to one side of the base plate 51, slides along one side and is compressed by the third spring 88, which is fixed to the fixing plate 87 and the second connecting plate 89. Then, the two limiting plates 86 limit the upper part of the operator's feet. The reamer body 4 then begins to rotate, and the cutting edge of the reamer body 4 begins to contact the borehole wall. By rotating and cutting the rock or soil, the diameter of the borehole is gradually enlarged. When the required diameter is reached, the rotation of the drill stops, completing the reaming operation. Then, the reamer body 4 separates from the drill rod 3.
