Description

Technical Field

[0001] The invention relates to the technical field of tunnel advance prediction, and in particular to a TSP drilling path stabilization and rapid arrangement device. Background Art

[0002] TSP drilling refers to a tunnel seismic wave prediction technology, and its full name is Tunnel Seismic Prediction. TSP technology is mainly used for advanced geological prediction during tunnel construction. The principle is to use the seismic wave reflection method to drill at least 18 blastholes at intervals on the side wall of one side of the tunnel, and drill 2 detector holes on the two side walls, and sequentially stimulate each explosive for small blasting, and use the propagation and reflection of seismic waves to predict the geological conditions. By using this prediction system, the geological conditions of the surrounding rock in front of the face can be understood, and then the distribution and properties of the unfavorable geological bodies in front and the hidden major geological problems can be predicted, providing a reliable basis for information-based design and construction, and reducing the risk of geological disasters.

[0003] In the application of TSP technology, the drilling of blastholes is a key link. Traditional drilling technology mainly relies on the drill rod to directly form a channel in the wall, but there are the following problems in the drilling process. First, the stability of the channel is poor. When the rock mass is broken or the soil is loose, it is easy to collapse after drilling, making it difficult to place explosives or detectors smoothly, affecting subsequent construction. Second, the operation is cumbersome. Based on the possibility of collapse, the depth of the borehole needs to be repeatedly measured after traditional drilling to ensure the smooth placement of explosives or detectors. This not only increases the construction time, but also requires the casing to be replaced after the drill rod is pulled out, which poses a risk of error accumulation. Third, the soil is inconvenient to clean, and the debris and soil generated by drilling are not easy to discharge. It is usually necessary to pull out the drill rod back and forth to bring out the soil, which affects the drilling efficiency. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a TSP drilling path stabilization and rapid arrangement device.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A TSP drilling path stabilization and rapid arrangement device comprises an integrally connected drill bit and a drill rod, the end of the drill rod away from the drill bit is provided with a connector for connecting to a hydraulic drilling vehicle, an outer sleeve is detachably sleeved on the outside of the drill rod, at least two groups of slide grooves parallel to the pipe axis are opened on the outer sleeve, a transmission assembly is arranged on the slide groove, the transmission assembly comprises a transmission belt, a first transmission wheel, a second transmission wheel, a third transmission wheel, a positioning plate and a positioning shaft, the first transmission wheel and the second transmission wheel are respectively arranged at the two ends of the slide groove through the positioning shaft, the two ends of the positioning plate are provided with shaft holes for the first transmission wheel and the second transmission wheel to pass through, an extension plate extending perpendicular to the pipe axis direction is provided at the end of the positioning plate close to the drill bit, the third transmission wheel is arranged at the end of the extension plate through the shaft hole, the inner ring of the transmission belt is rotationally connected with the first transmission wheel, the second transmission wheel and the third transmission wheel respectively;

[0007] The drill rod is respectively provided with a first bevel gear fixedly sleeved and a mounting collar movable sleeved, the first bevel gear being arranged at an end close to the drill bit, and at least two symmetrical L-shaped rods being arranged on the mounting collar, the end of the L-shaped rod guiding one side of the first bevel gear and being arranged parallel to the axis of the drill rod, the L-shaped rod being sequentially provided with a first gear and a second gear meshing with each other along the direction of the end, a second bevel gear being coaxially provided on the side of the first gear facing the drill rod, the second bevel gear meshing with the first bevel gear, a plurality of push plates being arranged at equal intervals on the outer ring of the transmission belt, the transmission assembly comprising a first transmission assembly and a second transmission assembly, the first transmission assembly being toothed with the first gear on one L-shaped rod through a push plate, and the second transmission assembly being toothed with the second gear on another L-shaped rod through a push plate.

[0008] Furthermore, the extension plate on the first transmission assembly vertically corresponds to the first gear on one L-shaped rod, and the extension plate on the second transmission assembly vertically corresponds to the second gear on another L-shaped rod. The drill rod is connected to the hydraulic drilling vehicle to drive the drill bit to rotate, and the rotation of the drill rod drives the first bevel gear to rotate. Since the first bevel gear is meshed with the second bevel gear, the rotation of the first bevel gear will drive the two second bevel gears to rotate in opposite directions respectively. The second bevel gear drives the first gear on the L-shaped rod to rotate, and the rotation of the first gear drives the second gear on the same L-shaped rod to rotate. In order to ensure that the direction of the transmission belt is consistent, the first transmission assembly is meshed with the first gear on one L-shaped rod, and the second transmission assembly is meshed with the second gear on another L-shaped rod.

[0009] Furthermore, the transmission belt is located on a side outside the chute and moves toward one end of the connector. In order to ensure that the transmission belt can carry soil or debris out of the blasthole through the push plate, the rotation direction of the two transmission belts must move toward one end of the connector. The direction of the drill bit is the front, the gear on the left side is engaged with the first transmission assembly, and the gear on the right side is engaged with the second transmission assembly. When the drill bit rotates clockwise, the upper end face of the first gear on the left side rotates in the direction of the drill bit, the upper end face of the first gear on the right side rotates in the direction of the connector, and the second gear on the right side rotates in the direction of the drill bit. The first transmission assembly is toothed with the first gear on the left side, and the second transmission assembly is toothed with the second gear on the right side. At this time, the lower end face of the first transmission assembly is toothed with the first gear on the left side, and the upper end face of the first transmission assembly moves toward one end of the connector. The lower end face of the second transmission assembly is toothed with the second gear on the right side, and the upper end face of the second transmission assembly moves toward one end of the connector.

[0010] Furthermore, the installation collar is provided with a raised positioning block, and the inner wall of the outer sleeve is provided with a positioning groove matched with the positioning block, and the positioning groove is parallel to the pipe axis of the outer sleeve. The first bevel gear is fixed to the drill rod and rotates with the drill rod. The installation collar is sleeved on the drill rod. In order to ensure that the installation collar does not rotate with it, the positioning block and the positioning groove are plugged in and matched to prevent the installation collar from rotating with it. Since the drill rod is inserted into the outer sleeve, the positioning groove is arranged along the axis of the outer sleeve, ensuring that the positioning block can also be inserted along the positioning groove during the insertion of the drill rod into the outer sleeve. When the drill rod rotates circumferentially, the installation collar will not rotate.

[0011] Furthermore, a limit baffle is provided at one end of the drill rod near the connector, the diameter of the limit baffle is larger than the diameter of the outer sleeve, and a first elastic component is provided between the limit baffle and the connector. In the process of the drill rod drilling into the soil layer, the hydraulic drilling vehicle not only applies rotational force to the drill rod, but also applies power to propel the inner layer of the soil. At this time, the limit baffle can drive the outer sleeve to follow the drill bit into the soil. In the process of the drill rod driving the outer sleeve to drill, due to the different external environment and geology, the drill rod may experience violent movement or occasional mechanical collision. The first elastic component can provide a buffer between the drill rod and the connector, so that there will be no excessive friction or collision between the connector and the drill rod, avoiding damage to the drill rod, the connector and related components. In addition, since the drill rod will be affected by many factors such as soil, rock formation, and pressure during the drilling process, the drill rod may sometimes get stuck during the drilling process. The elastic action provided by the first elastic component can cause appropriate relative displacement between the limit baffle and the connecting head, thereby effectively avoiding the problem of the drill rod getting stuck due to sticking, and automatically adjusting the position to ensure smooth drilling.

[0012] Furthermore, the outer peripheral wall of the drill bit is provided with several receiving grooves at equal intervals, and the receiving groove is rotatably connected with a raised stopper, and the movable end of the raised stopper is connected to the receiving groove through a second elastic component, and the second elastic component is arranged at one end close to the end of the drill bit. After the raised stopper is ejected, its ground-breaking radius increases and is greater than or equal to the outer diameter of the outer sleeve, so that the drill bit can smoothly guide the soil at the end to the transmission belt during the ground-breaking process, and guide the soil out of the blasthole through the movement of the transmission belt. After completing the ground-breaking operation, it is necessary to first withdraw the drill rod, and then withdraw the outer sleeve after completing the placement of explosives or detectors. When withdrawing the drill rod, since the rotating end of the raised stopper is arranged at one end close to the connector, after the raised stopper collides with the end of the outer sleeve, the raised stopper can be pressed into the outer sleeve, thereby smoothly withdrawing the drill rod.

[0013] Furthermore, the outer casing includes a casing layer and a wrapping layer, the wrapping layer covers the outer wall of the casing layer, and the wrapping layer is provided with a guide groove for the push plate to move, and the guide groove is connected to the slide groove. During the earth-breaking process, the outer wall of the wrapping layer contacts the hole wall of the blasthole, and the soil and debris broken at the drill bit enter the guide grooves of the wrapping layer in the circumferential direction, and the soil is brought out to the outside by the movement of the push plate.

[0014] Furthermore, the end face of the push plate does not exceed the outer end face of the wrapping layer. The guide groove provides a movable space for the push plate, which is used to throw the soil and debris on the soil entry surface into the guide groove, and the soil is guided out by the push plate movable on the guide groove. Since the outer wall of the wrapping layer contacts the hole wall of the blasthole, when the outer end face of the push plate does not exceed the outer end face of the wrapping layer, the normal movement of the push plate, that is, the normal operation of the transmission assembly, can be guaranteed.

[0015] Furthermore, the length of the wrapping layer is shorter than that of the casing layer, and the guide groove is provided with an arc guide at an opening at one end of the drill bit. The casing layer is provided with a circumferential soil accommodation space at one end close to the drill bit, that is, during the earth-breaking operation, soil or debris will enter the position of the soil accommodation space, and then enter each guide groove, and the soil or debris will be guided out through the transmission assembly. The arc guide setting is conducive to the soil entering the guide groove, thereby improving the transportation efficiency.

[0016] Furthermore, the vertical distance between the axis of the drill bit and the outer wall of the raised stopper is greater than the radius of the wrapping layer. After the raised stopper pops up, its breaking ground radius increases and is greater than the radius of the wrapping layer, so that during the process of the drill bit rotating to break ground, the soil at the end can be smoothly guided into the guide groove arranged in the circumferential direction, and the soil can be guided out of the blasthole through the movement of the transmission belt.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention can smoothly discharge the sudden or debris during the drilling operation of the drill rod by matching a detachable outer sleeve outside the drill rod and arranging a slide groove and a transmission assembly, and can also avoid the collapse of the channel caused by loose soil or broken rock during the drilling process, thereby improving the operation efficiency and safety;

[0019] 2. The present invention not only reduces the steps of repeated measurement and adjustment in traditional drilling, but also avoids the tedious operations of repeated drilling and casing placement, significantly reduces the construction time, and further simplifies the operation process;

[0020] 3. The present invention can reduce the repeated operations and delays common in traditional drilling technology, significantly reduce manual intervention and construction costs, and take into account the adaptability under a variety of different soil and rock conditions, ensuring the smooth progress of drilling and meeting the geological exploration needs of different tunnel construction.

DETAILED DESCRIPTION

[0028] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0029] Embodiment 1, as Figure 1-6 As shown, a TSP drilling path stabilization and rapid arrangement device disclosed in the present invention comprises an integrally connected drill bit 1 and a drill rod 2, wherein the end of the drill rod 2 away from the drill bit 1 is provided with a connector 3 for connecting to a hydraulic drilling vehicle, an outer sleeve 4 is detachably sleeved on the outside of the drill rod 2, and at least two groups of slide grooves 5 parallel to the pipe axis are opened on the outer sleeve 4, and a transmission assembly is arranged on the slide groove 5, and the transmission assembly comprises a transmission belt 6, a first transmission wheel 7, a second transmission wheel 8, a third transmission wheel 9, a positioning plate 10 and a positioning shaft, the first transmission wheel 7 and the second transmission wheel 8 are respectively arranged at the two ends of the slide groove 5 through the positioning shaft, and the two ends of the positioning plate 10 are provided with axial holes for the first transmission wheel 7 and the second transmission wheel 8 to pass through, and the end of the positioning plate 10 close to the drill bit 1 is provided with an extension plate 11 extending perpendicular to the pipe axis direction, and the third transmission wheel 9 is arranged at the end of the extension plate 11 through the axial hole, and the inner ring of the transmission belt 6 is rotatably connected with the first transmission wheel 7, the second transmission wheel 8 and the third transmission wheel 9 respectively.

[0030] The drill rod 2 is respectively provided with a first bevel gear 12 fixedly sleeved and a mounting collar 13 movably sleeved, the first bevel gear 12 is arranged at one end close to the drill bit 1, and at least two symmetrical L-shaped rods 14 are arranged on the mounting collar 13, the end of the L-shaped rod 14 guides one side of the first bevel gear 12 and is arranged parallel to the axis of the drill rod 2, the L-shaped rod 14 is sequentially provided with a first gear 15 and a second gear 16 meshing with each other along the direction of the end, the first gear 15 is coaxially provided with a second bevel gear 17 on the side facing the drill rod 2, the second bevel gear 17 is meshed with the first bevel gear 12, a plurality of push plates 18 are arranged at equal intervals on the outer ring of the transmission belt 6, the transmission assembly includes a first transmission assembly 19 and a second transmission assembly 20, the first transmission assembly 19 is toothed with the first gear 15 on one L-shaped rod 14 through the push plate 18, and the second transmission assembly 20 is toothed with the second gear 16 on the other L-shaped rod 14 through the push plate 18.

[0031] The extension plate 11 on the first transmission assembly 19 vertically corresponds to the first gear 15 on one L-shaped rod 14, and the extension plate 11 on the second transmission assembly 20 vertically corresponds to the second gear 16 on another L-shaped rod 14. Specifically, the drill rod 2 is connected to the hydraulic drilling vehicle to drive the drill bit 1 to rotate, and the rotation of the drill rod 2 drives the first bevel gear 12 to rotate. Since the first bevel gear 12 is meshed with the second bevel gear 17, the rotation of the first bevel gear 12 will drive the two second bevel gears 17 to rotate in the opposite direction. The second bevel gear 17 drives the first gear 15 on the L-shaped rod 14 to rotate, and the rotation of the first gear 15 drives the second gear 16 on the same L-shaped rod 14 to rotate. In order to ensure that the direction of the transmission belt 6 is consistent (for taking the soil out of the blasthole), the first transmission assembly 19 is meshed with the first gear 15 on one L-shaped rod 14, and the second transmission assembly 20 is meshed with the second gear 16 on another L-shaped rod 14.

[0032] The transmission belt 6 is located on one side outside the chute 5 and moves toward one end of the connector 3. Specifically, in order to ensure that the transmission belt 6 can carry soil or debris out of the blasthole through the push plate 18, the rotation direction of the two transmission belts 6 should move toward one end of the connector 3. Figure 2 As shown, the drill bit 1 is facing forward, the gear on the left is meshed with the first transmission assembly 19, and the gear on the right is meshed with the second transmission assembly 20. When the drill bit 1 rotates clockwise, the upper end face of the first gear 15 on the left rotates in the direction of the drill bit 1, the upper end face of the first gear 15 on the right rotates in the direction of the connector 3, and the second gear 16 on the right rotates in the direction of the drill bit 1. The first transmission assembly 19 is gear-engaged with the first gear 15 on the left, and the second transmission assembly 20 is gear-engaged with the second gear 16 on the right. At this time, Figure 4 As shown, the lower end face of the first transmission assembly 19 is geared with the first gear 15 on the left, and the upper end face of the first transmission assembly 19 moves toward one end of the connector 3. The lower end face of the second transmission assembly 20 is geared with the second gear 16 on the right, and the upper end face of the second transmission assembly 20 moves toward one end of the connector 3.

[0033] The mounting collar 13 is provided with a raised positioning block 21, and the inner wall of the outer sleeve 4 is provided with a positioning groove matched with the positioning block 21, and the positioning groove is parallel to the pipe axis of the outer sleeve 4. Specifically, the first bevel gear 12 is fixedly connected to the drill rod 2 and rotates with the drill rod 2. The mounting collar 13 is sleeved on the drill rod 2. In order to ensure that the mounting collar 13 does not rotate with it, the positioning block 21 is plugged into the positioning groove to prevent the mounting collar 13 from rotating with it. Since the drill rod 2 is inserted into the outer sleeve 4, the positioning groove is arranged along the axis of the outer sleeve 4, ensuring that the positioning block 21 can also be inserted along the positioning groove during the insertion of the drill rod 2 into the outer sleeve 4. When the drill rod 2 rotates circumferentially, the mounting collar 13 will not rotate. Preferably, the end of the outer sleeve 4 close to the connector 3, that is, the part of the outer sleeve 4 located outside the soil layer, is fixed by a fixed assembly to prevent the outer sleeve 4 from being driven to rotate with the rotation of the drill rod 2.

[0034] A limit baffle 22 is provided at one end of the drill rod 2 near the connector 3. The diameter of the limit baffle 22 is larger than the diameter of the outer sleeve 4. A first elastic component 23 is provided between the limit baffle 22 and the connector 3. Specifically, in the process of the drill rod 2 drilling into the soil layer, the hydraulic drilling vehicle not only applies a rotational force to the drill rod 2, but also applies a force to propel the inner layer of the soil. At this time, the limit baffle 22 can drive the outer sleeve 4 to follow the drill bit 1 to drill into the soil. In the process of the drill rod 2 driving the outer sleeve 4 to drill, due to the different external environment and geology, the drill rod 2 may experience violent movement or occasional mechanical collision. The first elastic component 23 can provide a buffer between the drill rod 2 and the connector 3, so that there will be no excessive friction or collision between the connector 3 and the drill rod 2, thereby avoiding damage to the drill rod 2, the connector and related components. In addition, since the drill rod 2 will be affected by many factors such as soil, rock formation, pressure, etc. during the drilling process, the drill rod 2 may sometimes get stuck during the drilling process. The elastic effect provided by the first elastic component 23 can cause appropriate relative displacement between the limit baffle 22 and the connecting head 3, thereby effectively avoiding the problem of the drill rod 2 being stuck due to sticking, and automatically adjusting the position to ensure smooth drilling.

[0035] The outer peripheral wall of the drill bit 1 is provided with a plurality of receiving grooves 24 at equal intervals, and the receiving grooves 24 are rotatably connected with a protruding stopper 25, and the movable end of the protruding stopper 25 is connected to the receiving groove 24 through a second elastic component 26, and the second elastic component 26 is arranged at one end close to the end of the drill bit 1. Specifically, after the protruding stopper 25 is bounced, its ground-breaking radius increases and is greater than or equal to the outer diameter of the outer sleeve 4, so that the drill bit 1 can smoothly guide the soil at the end to the transmission belt 6 during the ground-breaking process, and guide the soil out of the blasthole through the movement of the transmission belt 6. After the ground-breaking operation is completed, the drill rod 2 needs to be pulled out first, and the outer sleeve 4 needs to be pulled out after the placement of the explosive or the detector is completed. When the drill rod 2 is pulled out, since the rotating end of the protruding stopper 25 is arranged at one end close to the connector 3, after the protruding stopper 25 contacts the end of the outer sleeve 4, the protruding stopper 25 can be pressed into the outer sleeve 4, thereby smoothly pulling out the drill rod 2. Preferably, during the preparation operation, when the drill rod 2 is inserted into the outer sleeve 4, all the raised blocks 25 are contracted and squeezed by an annular sleeve-like device. At this time, the drill bit 1 is inserted into the outer sleeve 4, and then the annular sleeve-like device is taken out, and the drill bit 1 can be smoothly inserted into the outer sleeve 4.

[0036] The outer sleeve 4 includes a casing layer 401 and a wrapping layer 402, wherein the wrapping layer 402 covers the outer wall of the casing layer 401, and the wrapping layer 402 is provided with a guide groove 27 for the push plate 18 to move, and the guide groove 27 is connected to the slide groove 5. Specifically, during the earth-breaking process, the outer wall of the wrapping layer 402 contacts the hole wall of the blasthole, and at this time, the soil and debris broken at the drill bit 1 enter the guide grooves 27 of the circumferential direction of the wrapping layer 402, and the soil is brought out to the outside by the movement of the push plate 18.

[0037] The end face of the push plate 18 does not exceed the outer end face of the wrapping layer 402. Specifically, the guide groove 27 provides a movable space for the push plate 18, which is used to throw the soil and debris on the soil surface into the guide groove 27, and the soil is discharged through the push plate 18 movable on the guide groove 27. Since the outer wall of the wrapping layer 402 is in contact with the hole wall of the blasthole, when the outer end face of the push plate 18 does not exceed the outer end face of the wrapping layer 402, the normal movement of the push plate 18, that is, the normal operation of the transmission assembly, can be guaranteed.

[0038] The length of the wrapping layer 402 is less than that of the casing layer 401, and the guide groove 27 is arranged to guide the arc toward the opening at one end of the drill bit 1. Figure 1 It can be seen that the casing layer 401 is provided with a circumferential soil accommodation space at one end close to the drill bit 1, that is, during the earth-breaking operation, soil or debris will enter the position of the soil accommodation space, and then enter each guide groove 27, and the soil or debris will be guided out through the transmission assembly. The guide arc setting is conducive to the soil entering the guide groove 27, thereby improving the transportation efficiency.

[0039] The vertical distance between the axis of the drill bit 1 and the outer wall of the raised stopper 25 is greater than the radius of the wrapping layer 402. Specifically, after the raised stopper 25 pops up, its breaking ground radius increases and is greater than the radius of the wrapping layer 402, so that the drill bit 1 can smoothly guide the soil at the end into the circumferentially arranged guide groove 27 during the rotation breaking ground process, and guide the soil out of the blast hole through the movement of the transmission belt 6.

[0040] Embodiment 2: Based on embodiment 1, this embodiment proposes a specific working principle of a TSP drilling path stabilization and rapid arrangement device.

[0041] The specific implementation principle process is as follows:

[0042] The drill rod 2 is connected to the hydraulic drilling vehicle through the connector 3, and all the raised blocks 25 are shrunk and squeezed by the annular casing-like equipment. At this time, the drill bit 1 is inserted into the outer sleeve 4, and then the annular casing-like equipment is taken out, and the drill bit 1 is smoothly inserted into the outer sleeve 4 to complete the preparation operation.

[0043] During the drilling process, the hydraulic drilling vehicle drives the drill rod 2 to rotate. As the drill rod 2 rotates, the drill bit 1 begins to break the soil in the soil layer. The rotation of the drill bit 1 is transmitted to the second bevel gear 17 through the first bevel gear 12, and drives the gear on the L-shaped rod 14 to rotate. The transmission belt 6 thus begins to move along the axial direction of the outer sleeve 4 in the slide groove 5, driving the push plate 18 to move in the guide groove 27. As the drill bit 1 rotates, the first gear 15 and the second gear 16 rotate accordingly, thereby driving the first transmission assembly 19 and the second transmission assembly 20 to rotate, so that the outer end face of the transmission belt 6 rotates outside the blast hole, and the soil and debris are taken out through the guide groove 27. In order to prevent the drill rod 2 from interfering with the outer sleeve 4, a positioning groove is provided on the inner wall of the outer sleeve 4 to cooperate with the positioning block 21 on the mounting collar 13. It is ensured that the mounting collar 13 does not rotate with the drill rod 2, so that the outer sleeve 4 always remains stable during the drilling process.

[0044] After the drilling operation is completed, the drill rod 2 needs to be pulled out first, and the outer sleeve 4 needs to be left in the blast hole to prevent the collapse of the soil from affecting the placement of the explosives or detectors. When withdrawing, the second elastic component 26 is abutted and compressed, and the raised stopper 25 is pressed into the outer sleeve 4, so that the drill rod 2 can be smoothly pulled out. Finally, the explosives or detectors are introduced into the outer sleeve 4, and the outer sleeve 4 is slowly pulled out by the power equipment to ensure that the explosives or detectors are accurately placed in the appropriate position, completing the entire operation of breaking the ground and placing the explosives. Through the cooperation of the drill rod 2 and the outer sleeve 4, the process of efficient drilling, soil guiding, soil layer fixation and explosive placement is realized, ensuring the stability and rapid arrangement of the drilling path.

[0045] In addition, in order to improve the soil guiding efficiency, two slide grooves 5 are provided on the outer wall of the outer sleeve 4, on the vertical corresponding surface of the slide groove 5, and the two slide grooves 5 are equipped with transmission components. The two transmission components are respectively engaged with the first gear 15 and the second gear 16 according to the principle that the outer end surface of the transmission belt 6 guides one end of the connector 3, and the connection surface is the bottom surface of the first gear 15 and the second gear 16. By providing four sets of transmission components, the soil guiding efficiency can be further improved, that is, the rotation speed of the drill rod 2 can be increased.

[0046] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
