Description

Technical Field

[0001] This invention relates to the field of exploration technology, and more specifically, to a drilling device for metal ore exploration and its method of use. Background Technology

[0002] Metal mineral exploration aims to understand the geological processes and ore-controlling factors that lead to the formation of mineral deposits, thereby revealing the formation and distribution patterns of these deposits. Metal mineral exploration is a complex and technology-intensive task that requires the use of various equipment and tools to collect and analyze geological data. Among these tools, drilling equipment is a crucial one, as it can directly penetrate underground rock to obtain key information about the existence of mineral deposits, their depth, thickness, and grade.

[0003] According to Chinese Patent Publication No. CN113404435B, an eccentric drill bit and drilling equipment are disclosed, including a drilling section and a connecting section connected to each other; the drilling section includes a plurality of blades arranged at equal angles, each blade is provided with a cutting element, a chip removal groove is provided between two adjacent blades, and a spray hole is provided in the chip removal groove; each blade includes a reinforcing blade. This patent utilizes the offset setting of the reinforcing blade to make the drilled hole diameter slightly larger than the maximum diameter of the drill bit, thereby effectively preventing the problem of stuck drill bit.

[0004] While the aforementioned patent effectively prevents the drill bit from getting stuck, during geological drilling, the connection between the drill bit and the drill rod may break due to complex geological conditions. In this case, the drill rod needs to be raised and special equipment needs to be used to remove the broken drill bit. This process is not only troublesome but also time-consuming, thus increasing the operating costs. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention proposes a drilling equipment for metal mine exploration and a method of using it.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drilling device for metal ore exploration, comprising a drill rod installed at the bottom of a drilling machine, a drill bit threadedly connected to the bottom end of the drill rod, multiple sets of cutter wings fixedly connected to the outer side of the drill bit, a slag discharge hole opened inside the drill bit, the slag discharge hole, the drill bit, and the drill rod being interconnected, and a hoop ring fitted on the outer side of the drill rod, characterized in that; it further comprises; A clamping mechanism is provided on the outside of the hoop, and a clamping plate is provided at the bottom end of the clamping mechanism.

[0007] Furthermore, the clamping mechanism includes three sets of L-shaped plates, all of which are fixed to the outside of the hoop. Each of the three sets of L-shaped plates has a pair of support rods inside. One end of each pair of support rods is fixed to the outside of the hoop, and the end of each pair of support rods away from the hoop is fixed to the L-shaped plate. A clamping plate is slidably connected to the outside of each pair of support rods. A first compression spring is fixed between the clamping plate and the L-shaped plate.

A clamping groove is formed on the outside of the drill bit, and the clamping groove is positioned above the stop rod.

[0008] Furthermore, the detection mechanism includes a pressure sensor, which is installed on the outside of the drill rod. The pressure sensor and the drilling machine are respectively connected to an external control terminal via radio. The external control terminal can receive the value of the pressure sensor and control the start and stop of the drilling machine. The pressure sensor is used to sense whether the connection between the drill rod and the drill bit is broken.

[0009] Furthermore, the bottom end of the drill bit is provided with a device groove, and a drill cone is provided inside the device groove. Multiple sets of friction teeth are fixed to the bottom end of the outer side of the drill cone. The friction teeth are used to increase the friction between the drill cone and the outside. A sliding plate is fixed to the outer side of the drill cone. A fixing ring is fixed to the inner wall of the device groove. A pair of first limiting rods are fixed between the fixing ring and the device groove. Both of the first limiting rods pass through the sliding plate. A pressurizing mechanism is provided inside the device groove. The pressurizing mechanism is used to increase the pressure of the broken geological formation.

[0010] Furthermore, the pressurizing mechanism includes a limiting ring, with multiple sets of fixed round rods fixed to the outer side of the limiting ring. The ends of the multiple sets of fixed round rods away from the limiting ring are fixed to the device groove. A fixing plate is fixed to the inner wall of the device groove. A transmission block is slidably connected to the outer side of the limiting ring. A tension spring is fixed between the fixing plate and the transmission block. An inclined block is fixed to the top of the sliding plate. A first arc rod is fixed to the end of the transmission block away from the inclined block. A friction plate is fixed to the end of the first arc rod away from the friction plate. The friction plate penetrates the sliding plate. The bottom end of the friction plate is slightly lower than the bottom end of the blade. A limiting groove is formed inside the sliding plate. A second arc rod is fixed to the inner wall of the limiting groove. The second arc rod penetrates the friction plate. Both the second and first arc rods are arc-shaped. A guide block is fixed to the top of the fixing ring. The cross-section of the guide block is a right triangle. The right-angled side of the right triangle is located at the bottom of the sliding plate.

[0011] Furthermore, multiple sets of fixing blocks are fixed to the outside of the drill rod, and each set of fixing blocks is equipped with a friction roller. A compaction mechanism is provided inside the fixing block to compress the soil. A delay mechanism is provided between the compaction mechanism and the drill rod to delay the movement of the friction roller.

[0012] Furthermore, the compaction mechanism includes extrusion grooves, which are symmetrically arranged inside multiple sets of fixed blocks. A second limiting rod is fixedly connected inside each pair of extrusion grooves. An extrusion block is slidably connected to the outside of each pair of second limiting rods. A connecting rod is fixedly connected between a pair of extrusion blocks. The friction roller is rotatably connected to the outside of the connecting rod. A second compression spring is fixedly connected between the extrusion block and the extrusion groove.

[0013] Furthermore, the delay mechanism includes a pair of connecting rings, both of which are fixed to the outside of the connecting rod. A fixed square rod is fixed to the outside of each pair of connecting rings. A connecting plate is fixed to the end of the fixed square rod away from the connecting ring. A first hook and loop fastener is glued to the end of the connecting plate opposite to the fixed square rod. A second hook and loop fastener is glued to the end of the first hook and loop fastener opposite to the connecting plate. The end of the second hook and loop fastener opposite to the first hook and loop fastener is glued to the outside of the drill rod.

[0014] The technical effects and advantages of the drilling equipment and its usage method for metal ore exploration according to the present invention are as follows: (1) Through the structural design of the clamping mechanism, when the connection between the drill rod and the drill bit breaks, the clamping mechanism will operate instantly to clamp the outside of the drill bit. The operator can then pull up the drill rod to drive the drill bit through the pull-up mechanism, thereby avoiding the need to use special equipment to remove the drill bit, improving the convenience of removing the drill bit and reducing the working cost.

[0015] (2) Through the design of the pressurization mechanism and the drill bit, when the drill bit faces a hard geological surface, the pressurization mechanism drives the drill bit to move down, and the drill bit loosens the local soil and rock of the geological surface, which disrupts the pressure balance around the geological surface. This makes it easier for the drill bit to drive the blade to rotate and loosen the soil and rock, greatly increasing the drilling time required by the drill bit and improving work efficiency.

[0016] (3) Through the structural design of the compaction mechanism and the friction roller, the compaction mechanism drives the friction roller to rotate along the inner wall of the drilled soil during the movement process, thereby compacting the soil and effectively avoiding the situation where the drill bit causes the soil to loosen, resulting in soil accumulation on the surface of the drill bit and increasing the weight of the drill bit.

Detailed Implementation

[0028] 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. 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.

[0029] Please see Figure 1 - Figure 4 As shown, a drilling device for metal ore exploration includes a drill rod 1 installed at the bottom of a drilling machine, a drill bit 2 threadedly connected to the bottom end of the drill rod 1, multiple sets of cutter wings 3 fixedly connected to the outside of the drill bit 2, a slag discharge hole 4 opened inside the drill bit 2, the slag discharge hole 4, the drill bit 2 and the drill rod 1 communicating with each other, and a hoop 5 sleeved on the outside of the drill rod 1. The device is characterized by further comprising: A clamping mechanism is provided on the outside of the hoop 5, and a clamping plate 6 is provided at the bottom end of the clamping mechanism. The clamping mechanism is used to drive the clamping plate 6 to clamp the drill bit 2. A detection mechanism is installed on the outside of the drill pipe 1, which is used to detect the real-time status of the drill pipe 1 and the drill bit 2.

[0030] First, the end of drill rod 1 furthest from drill bit 2 is installed at the output end of the drilling rig (the drilling rig in this article is existing technology and mature, not shown in the figure; the output end of the drilling rig can drive drill rod 1 to rotate during operation, thereby causing the cutter blades 3 on the outside of drill bit 2 to contact the geological surface, achieving the function of rotary drilling). During geological drilling, the connection between drill rod 1 and drill bit 2 may break due to complex geological conditions. In this case, drill rod 1 needs to be raised, and the broken drill bit 2 needs to be removed using specialized equipment. This process is not only troublesome but also time-consuming, thus increasing operating costs. To solve the above problems, in the initial state of use, the embodiment of this invention... Drill rod 1 and drill bit 2 are connected together by threads. At the same time, the clamping mechanism on the outside of drill bit 2 is in a compressed state and is not attached to the outside of drill bit 2. When the connection between drill rod 1 and drill bit 2 breaks, drill rod 1 and drill bit 2 split. The detection mechanism senses this instantly and controls the drilling machine to shut down. At this time, drill rod 1 and drill bit 2 are stationary and stop rotating. Because of the break between drill rod 1 and drill bit 2, the clamping mechanism will operate instantly to clamp the outside of drill bit 2. The operator can then pull up drill rod 1 to pull up drill bit 2, thus avoiding the need for special equipment to remove drill bit 2, improving the convenience of removing drill bit 2 and reducing working costs.

[0031] like Figure 1 - Figure 4As shown, the clamping mechanism includes three sets of L-shaped plates 7. All three sets of L-shaped plates 7 are fixed to the outside of the hoop 5. Each set of L-shaped plates 7 has a pair of support rods 8 inside. One end of the pair of support rods 8 is fixed to the outside of the hoop 5, and the end of the pair of support rods 8 away from the hoop 5 is fixed to the L-shaped plate 7. A clamping plate 6 is slidably connected to the outside of the pair of support rods 8. A first compression spring 9 is fixed between the clamping plate 6 and the L-shaped plate 7. A stop rod 60 is slidably connected to the bottom end of the clamping plate 6. The end of the stop rod 60 away from the clamping plate 6 is fixed to the outside of the drill bit 2. A clamping groove 10 is opened on the outside of the drill bit 2. The clamping groove 10 is located above the stop rod 60.

[0032] To achieve the function of clamping drill bit 2 when the connection between drill rod 1 and drill bit 2 breaks, in the initial state, the stop bar 60 on the outside of drill bit 2 constantly presses against the inclined surface of clamping plate 6, causing clamping plate 6 to press against the first compression spring 9, thereby deforming the first compression spring 9 and generating elastic potential energy. When the connection between drill rod 1 and drill bit 2 breaks, drill rod 1 and drill bit 2 separate, and the stop bar 60 on the outside of drill bit 2 stops pressing against clamping plate 6. The pressing of clamping plate 6 against the first compression spring 9 then comes to an end, and the first compression spring 9 releases its elastic potential energy instantaneously, pushing clamping plate 6 to move along support rod 8. When clamping plate 6 moves, it presses against clamping groove 10, thereby engaging inside clamping groove 10. At this time, clamping plate 6 performs the function of clamping drill bit 2. Then, the operator only needs to pull up drill rod 1, which in turn drives clamping plate 6 to rise. When clamping plate 6 rises, it abuts against the inner wall of clamping groove 10 and drives drill bit 2 to rise, allowing the operator to remove drill bit 2.

[0033] like Figure 1 - Figure 4 As shown, the detection mechanism includes a pressure sensor, which is installed on the outside of the drill rod 1. The pressure sensor and the drilling machine are respectively connected to an external control terminal via radio. The external control terminal can receive the value of the pressure sensor and control the start and stop of the drilling machine. The pressure sensor is used to sense whether the connection between the drill rod 1 and the drill bit 2 is broken.

[0034] To detect whether drill rod 1 and drill bit 2 are broken, when drill rod 1 and drill bit 2 are in normal working order, the pressure sensor detects that they bear the same pressure when rotating. When a break occurs at the connection between drill rod 1 and drill bit 2, the pressure sensor detects that the pressure on drill rod 1 is higher because it is still rotating due to the influence of the drilling rig, while drill bit 2 is not rotating and therefore experiences lower pressure. Upon detecting this, the pressure sensor immediately transmits the value to the external control terminal. The external control terminal then stops the drilling rig and issues an alarm to alert the operators. This structural design effectively prevents situations where, after drill rod 1 and drill bit 2 separate, the separation information cannot be obtained in time, and the drilling rig remains running. If drill rod 1 rotates while drill bit 2 does not, the clamping mechanism on the outside of drill rod 1 may not be able to effectively clamp drill bit 2, potentially leading to property damage.

[0035] like Figure 5 - Figure 7 As shown, the bottom end of the drill bit 2 is provided with a device groove, and a drill cone 11 is provided inside the device groove. Multiple sets of friction teeth are fixed to the bottom end of the outer side of the drill cone 11. The friction teeth are used to increase the friction between the drill cone 11 and the outside. A sliding plate 12 is fixed to the outer side of the drill cone 11. A fixing ring 13 is fixed to the inner wall of the device groove. A pair of first limiting rods 14 are fixed between the fixing ring 13 and the device groove. Both of the first limiting rods 14 pass through the sliding plate 12. A pressure boosting mechanism is provided inside the device groove. The pressure boosting mechanism is used to increase the pressure of the broken geological formation.

[0036] When drill bit 2 drills underground, the underground pressure gradually increases as you go deeper, leading to an increase in rock density and making it harder. Since the drilling area of ​​drill bit 2 is fixed due to its diameter, the pressure on the contact area of ​​drill bit 2 increases as you drill deeper, resulting in poorer drilling performance and a lower drilling rate. To address this issue, in this embodiment of the invention, in the initial state, the drill cone 11 is pulled by the pressure boosting mechanism and is located inside the device slot at the bottom of drill bit 2. When drill bit 2 drills in soft ground, it drives the blades 3 to rotate and penetrate deeper into the ground. At this time, the pressure boosting mechanism experiences relatively little friction, so it remains stationary or rotates slightly. The drill cone 11 remains inside the device slot, and drilling is mainly achieved by the blades 3. When drill bit 2 drives the blades 3 to drill in harder geological conditions, the pressure on the blades 3 increases. As the friction increases, the pressure on the booster mechanism also increases. When the drill bit 2 rotates, the booster mechanism experiences greater resistance, causing the drill cone 11 to descend. At this time, the drill cone 11, affected by the rotation of the drill bit 2, also drives the friction teeth on its outer side to rotate. At this time, the geology directly below the drill cone 11 will first contact the friction teeth on the surface of the drill cone 11. When the drill cone 11 drives the friction teeth to rotate, it will loosen the soil and rocks. It should be noted that since the diameter of the drill cone 11 is smaller than the diameter of the drill bit 2, the smaller the pressure the drill cone 11 bears when drilling the geology, the less power is required for drilling. At this time, the drill cone 11 loosens the local soil and rocks of the geology, disrupting the pressure balance around the geology. This makes it easier for the drill bit 2 to drive the blade 3 to rotate and loosen the soil and rocks, greatly increasing the drilling time required by the drill bit 2 and improving work efficiency.

[0037] like Figure 5 - Figure 7As shown, the pressurizing mechanism includes a limiting ring 15. Multiple sets of fixed round rods 16 are fixedly connected to the outer side of the limiting ring 15. The ends of the multiple sets of fixed round rods 16 away from the limiting ring 15 are fixedly connected to a device groove. A fixing plate 17 is fixedly connected to the inner wall of the device groove. A transmission block 18 is slidably connected to the outer side of the limiting ring 15. A tension spring 19 is fixedly connected between the fixing plate 17 and the transmission block 18. A wedge block 20 is fixedly connected to the top of the sliding plate 12. A first arc rod 21 is fixedly connected to the end of the transmission block 18 away from the wedge block 20. The first arc rod 21 is away from friction. A friction plate 22 is fixedly connected to one end of the plate 22. The friction plate 22 passes through the sliding plate 12. The bottom end of the friction plate 22 is slightly lower than the bottom end of the blade 3. A limiting groove is opened inside the sliding plate 12. A second arc rod 23 is fixedly connected to the inner wall of the limiting groove. The second arc rod 23 passes through the friction plate 22. Both the second arc rod 23 and the first arc rod 21 are arc-shaped. A guide block 24 is fixedly connected to the top of the fixing ring 13. The cross-section of the guide block 24 is a right triangle. The right-angled side of the right triangle is located at the bottom end of the sliding plate 12.

[0038] Initially, the friction between the friction plate 22 and the soil and rock is small, and the frictional force cannot overcome the tension of the tension spring 19. Therefore, the tension spring 19 drives the first arc rod 21 to remain stationary or rotate slightly through the transmission block 18. The first arc rod 21 then drives the friction plate 22 to remain stationary or rotate slightly. At this time, the drill bit 11 is inside the device groove. When encountering soil and rock with greater hardness, the friction between the friction plate 22 and the soil and rock is large, and the drill bit 2 then... Figure 6The drill bit 2 rotates clockwise, but the friction plate 22 cannot rotate due to friction from the soil and rocks. At this time, the drill bit 2 drives the sliding plate 12 to rotate via the first limit rod 14. The rotation of the sliding plate 12 will drive the inclined block 20 to rotate. During the rotation of the inclined block 20, it will contact and squeeze the transmission block 18. Since the transmission block 18 is fixed to the friction plate 22 via the first arc rod 21, and the friction plate 22 cannot rotate clockwise due to friction from the soil and rocks, the inclined block 20 is blocked by the transmission block 18 when rotating clockwise. As the inclined block 20 continues to rotate, it will move downward along the inclined surface of the transmission block 18. The rotation of the sliding plate 12 will also drive the second arc rod 23 to rotate along the inside of the friction plate 22. As the drill bit 2 rotates, it drives the fixed plate 17 to rotate, which will pull the tension spring 19, causing the tension spring 19 to deform and store energy. When the drill bit 2 drives the fixed ring 13 to rotate, the fixed ring 13 is blocked by the friction plate 22, and the inclined block 20 will stop descending. At this time, the inclined block 20 has not completely passed the transmission block 18, and the downward movement of the sliding plate 12 will synchronously drive the drill bit 11 to move downward. At this time, the drill bit 11, in conjunction with the rotation of the drill bit 2, and the friction plate 22, in conjunction with the friction of the geological soil, can keep the drill bit 11 in the state of extending out of the device slot. When the drill bit 2 rotates, the drill bit 11 and the friction plate 22 will contact the geological soil first, resulting in a smaller drilling area and making drilling more convenient. This provides a foundation for the drill bit 2 to drive the cutter wing 3 to drill the geological soil. After the drilling of hard soil and rock is completed, the friction force on the friction plate 22 decreases, and the tension force on the tension spring 19 decreases. The tension spring 19 releases potential energy and pulls the friction plate 22 back to its original position through the transmission block 18 and the first arc rod 21, making it convenient for the next use. The guide block 24 is set so that when soil and rock enter the device slot, the inclined surface of the guide block 24 can more easily discharge the soil and rock by gravity along the inclined surface, avoiding the accumulation of soil inside the device slot.

[0039] like Figure 8 - Figure 10 As shown, multiple sets of fixing blocks 25 are fixed to the outside of the drill rod 1. Each set of fixing blocks 25 is equipped with a friction roller 26. A compaction mechanism is provided inside the fixing block 25. The compaction mechanism is used to compress the soil. A delay mechanism is provided between the compaction mechanism and the drill rod 1. The delay mechanism is used to delay the movement of the friction roller 26.

[0040] When drill rod 1 and drill bit 2 are removed, drill bit 2 loosens the soil and rock, causing soil and rock to accumulate on the surface of drill bit 2, increasing its weight. This means that if the connection between drill bit 2 and drill rod 1 is broken, each increase in the weight of drill bit 2 may increase the pressure on the clamping mechanism, potentially preventing it from effectively holding the drill bit 2. To avoid this, in this embodiment of the invention, when drill rod 1 and drill bit 2 are inserted into the geological soil, a delay mechanism is first used to adhere and compact the mechanism. The compaction mechanism is then close to drill rod 1, which in turn drives the friction roller 26 closer to drill rod 1. At this time, the friction... Roller 26 is closer to the center point of drill rod 1 than blade 3. When drill rod 1 and drill bit 2 penetrate deep into the soil, the delay mechanism ends the adhesion to the compaction mechanism. The compaction mechanism then drives friction roller 26 away from the center point of drill rod 1 than blade 3. When drill rod 1 moves downward, friction roller 26 rotates along the inner wall of the drill hole soil to compact the soil. When drill rod 1 and drill bit 2 rise and reset, friction roller 26 compacts the drill hole soil a second time. At this time, blade 3 on the surface of drill bit 2 cannot contact the inner wall of the soil, thus effectively preventing the drill bit 2 from loosening the soil and causing soil to accumulate on the surface of drill bit 2, increasing the weight of drill bit 2.

[0041] like Figure 8 - Figure 10 As shown, the compaction mechanism includes an extrusion groove 27, which is symmetrically arranged inside multiple sets of fixed blocks 25. A second limiting rod 28 is fixedly connected inside each pair of extrusion grooves 27. An extrusion block 29 is slidably connected to the outside of each pair of second limiting rods 28. A connecting rod is fixedly connected between a pair of extrusion blocks 29. The friction roller 26 is rotatably connected to the outside of the connecting rod. A second compression spring 30 is fixedly connected between the extrusion block 29 and the extrusion groove 27.

[0042] To achieve soil compaction, in the initial state, the friction roller 26 is pushed close to the drill rod 1. The drill rod 1 then moves the extrusion block 29 via the connecting rod. The movement of the extrusion block 29 compresses the second compression spring 30, causing it to deform and generate elastic potential energy. At this time, the delay mechanism operates, and the connecting rod is affected by the delay mechanism, causing its friction roller 26 to be closer to the center point of the drill rod 1 than the cutter blade 3. When the drill rod 1 and drill bit 2 are deeply embedded in the soil, the effect of the delay mechanism on the connecting rod ends, and the second compression spring 30... The elastic potential energy is released instantly, and the connecting rod is reset through the extrusion block 29. The reset of the connecting rod will drive the friction roller 26 to reset. At this time, the friction roller 26 is farther away from the center point of the drill rod 1 than the cutter blade 3. When the drill rod 1 and the drill bit 2 continue to move into the soil, the friction roller 26 can squeeze and rotate along the inner wall of the soil, thereby compacting the soil and preventing it from loosening. When the drill rod 1 and the drill bit 2 are removed, the friction roller 26 moves along the inner wall of the soil again for secondary compaction, effectively compacting the soil.

[0043] like Figure 9 and Figure 10 As shown, the delay mechanism includes a pair of connecting rings 31, both of which are fixed to the outside of the connecting rod. A fixed square rod 32 is fixed to the outside of each of the connecting rings 31. A connecting plate 33 is fixed to the end of the fixed square rod 32 away from the connecting rings 31. A first hook and loop fastener 34 is glued to the end of the connecting plate 33 away from the fixed square rod 32. A second hook and loop fastener 35 is glued to the end of the first hook and loop fastener 34 away from the connecting plate 33. The end of the second hook and loop fastener 35 away from the first hook and loop fastener 34 is glued to the outside of the drill rod 1.

[0044] If, in the initial state, the friction roller 26 is farther from the center point of the cutter blade 3 than the cutter blade 3, when the drill rod 1 rotates, the friction roller 26 will contact the soil before the cutter blade 3. The hardness of the soil may cause the lateral rotation of the friction roller 26 to be obstructed, leading to damage to the friction roller 26. To solve the above problem, in this embodiment of the invention, the first hook and loop fastener 34 is first attached to the surface of the second hook and loop fastener 35. It should be noted that the adhesive strength is greater at the opposite ends of the first hook and loop fastener 34 and the second hook and loop fastener 35. At this time, the first hook and loop fastener 34 drives the connecting ring 31 to move towards the position of the drill rod 1 through the fixed square rod 32, and the connecting ring 31 drives the friction roller 26 to move through the connecting rod, while simultaneously driving the extrusion block 29 to compress the second compression spring 30, causing the second compression spring 30 to deform and generate elastic potential. Yes, at this time, when the drill rod 1 and drill bit 2 rotate again, the friction roller 26 slightly contacts the hard soil, effectively avoiding damage to the friction roller 26. As time goes by, the adhesion between the first hook and loop fastener 34 and the second hook and loop fastener 35 gradually becomes unable to overcome the elastic potential energy of the second compression spring 30, and will then separate. The second compression spring 30 then drives the friction roller 26 to move away from the drill rod 1. At this time, when the friction roller 26 rotates laterally, it contacts the soil that has been loosened by the rotation of the cutter blade 3, and its hardness is greatly reduced, which greatly reduces the damage to the friction roller 26. Since the adhesion between the first hook and loop fastener 34 and the second hook and loop fastener 35 may come into contact with the soil, resulting in a decrease in adhesion, the first hook and loop fastener 34 and the second hook and loop fastener 35 can be replaced after each work is completed.

[0045] Working Principle: First, the end of drill rod 1 furthest from drill bit 2 is installed at the output end of the drilling machine (the drilling machine in this article is existing technology and mature, not shown in the figure; the output end of the drilling machine can drive drill rod 1 to rotate during operation, thereby causing the cutter blades 3 on the outside of drill bit 2 to contact the geological surface, achieving the function of rotary drilling). During geological drilling, the connection between drill rod 1 and drill bit 2 may break due to complex geological conditions. In this case, drill rod 1 needs to be raised, and the broken drill bit 2 needs to be removed using specialized equipment. This process is not only troublesome but also time-consuming, thus increasing operating costs. To solve the above problems, in the embodiment of this invention, in the initial state, drill rod 1 and drill bit 2 are connected together by threads. At the same time, the drill... The clamping mechanism on the outer side of drill bit 2 is in a compressed state and not attached to the outer side of drill bit 2. When a break occurs at the connection between drill rod 1 and drill bit 2, drill rod 1 and drill bit 2 split. The detection mechanism senses this instantly and controls the drilling machine to shut down. At this time, drill rod 1 and drill bit 2 are stationary and stop rotating. Due to the break between drill rod 1 and drill bit 2, the clamping mechanism will operate instantly to clamp the outer side of drill bit 2. The operator can then pull up drill rod 1 to pull up drill bit 2, thus avoiding the need for special equipment to remove drill bit 2, improving the convenience of removing drill bit 2 and reducing operating costs. In order to achieve the function of clamping drill bit 2 when the connection between drill rod 1 and drill bit 2 breaks, in the initial state, the stop bar 60 on the outer side of drill bit 2 always compresses the clamp. The inclined surface of the clamping plate 6 causes it to compress the first compression spring 9, thereby deforming the first compression spring 9 and generating elastic potential energy. When the connection between the drill rod 1 and the drill bit 2 breaks, the drill rod 1 and the drill bit 2 separate. The compression of the clamping plate 6 by the stop rod 60 on the outside of the drill bit 2 ends, and the compression of the first compression spring 9 by the clamping plate 6 comes to an end. The first compression spring 9 releases its elastic potential energy instantaneously, pushing the clamping plate 6 to move along the support rod 8. When the clamping plate 6 moves, it will compress the clamping groove 10, thereby engaging inside the clamping groove 10. At this time, the clamping plate 6 performs the function of clamping the drill bit 2. Then, the operator only needs to pull up the drill rod 1, which in turn drives the clamping plate 6 to rise. When the clamping plate 6 rises, it abuts against the inner wall of the clamping groove 10 and drives the drill bit 2 to rise. Once the drill bit 2 is removed, the operator can retrieve it. To detect whether drill rod 1 and drill bit 2 are broken, when both are in normal working order, the pressure sensor detects that they bear the same pressure during rotation. However, if a break occurs at the connection between drill rod 1 and drill bit 2, the pressure sensor detects a higher pressure on drill rod 1 because it continues to rotate due to the drilling rig's influence, while drill bit 2 remains stationary and experiences less pressure. Upon detecting this, the pressure sensor immediately transmits the value to the external control unit, which then stops the drilling rig and issues an alarm to alert the operator. This structural design effectively prevents the drill rod 1 and drill bit 2 from separating.If separation information cannot be obtained in time, and the drilling rig remains running, with drill rod 1 rotating while drill bit 2 does not, the clamping mechanism on the outside of drill rod 1 may not be able to effectively clamp drill bit 2, potentially leading to property damage. To detect whether drill rod 1 and drill bit 2 are broken, when drill rod 1 and drill bit 2 are in normal condition, the pressure sensor detects that they bear the same pressure when rotating. When a break occurs at the connection between drill rod 1 and drill bit 2, the pressure sensor detects that the pressure on drill rod 1 is higher because it is still rotating due to the drilling rig's influence, while drill bit 2 is not rotating and therefore experiences lower pressure. Upon detecting this, the pressure sensor immediately transmits the value to the external control terminal, which then stops the drilling rig. The above structural design effectively prevents situations where, after the drill rod 1 and drill bit 2 separate, the separation information cannot be obtained in time while the drilling machine remains running, with the drill rod 1 rotating but the drill bit 2 not rotating. This can easily lead to the clamping mechanism on the outside of the drill rod 1 failing to effectively clamp the drill bit 2, resulting in property damage. In the initial state, the friction between the friction plate 22 and the soil and rock is small, and the friction force cannot overcome the tension of the tension spring 19. Therefore, the tension spring 19 drives the first arc rod 21 to remain stationary or rotate slightly through the transmission block 18. The first arc rod 21 then drives the friction plate 22 to remain stationary or rotate slightly. At this time, the drill cone 11 is inside the device groove. When encountering soil and rock with high hardness, the friction between the friction plate 22 and the soil and rock is large, and the drill bit 2 is at this time... Figure 6The drill bit 2 rotates clockwise, but the friction plate 22 cannot rotate due to friction from the soil and rocks. At this time, the drill bit 2 drives the sliding plate 12 to rotate via the first limiting rod 14. The rotation of the sliding plate 12 then drives the inclined block 20 to rotate. During the rotation of the inclined block 20, it contacts and presses against the transmission block 18. Since the transmission block 18 is fixed to the friction plate 22 via the first arc rod 21, and the friction plate 22 cannot rotate clockwise due to friction from the soil and rocks, the inclined block 20 is blocked by the transmission block 18 during clockwise rotation. As the inclined block 20 continues to rotate, it moves downwards along the inclined surface of the transmission block 18. The rotation of the sliding plate 12 also synchronously drives the second arc rod 23 to rotate along the interior of the friction plate 22. As the drill bit 2 rotates... When the drill bit 2 drives the fixed plate 17 to rotate, it pulls the tension spring 19, causing the tension spring 19 to deform and store energy. When the drill bit 2 drives the fixed ring 13 to rotate, the fixed ring 13 is blocked by the friction plate 22, and the inclined block 20 stops descending. At this time, the inclined block 20 has not completely passed the transmission block 18, and the sliding plate 12 moves downward, which synchronously drives the drill bit 11 to move downward. At this time, the drill bit 11, in conjunction with the rotation of the drill bit 2, and the friction plate 22, in conjunction with the friction of the geological soil, can keep the drill bit 11 in the state of extending out of the device slot. When the drill bit 2 rotates, the drill bit 11 and the friction plate 22 will first contact the geological soil, resulting in a smaller drilling area and making drilling easier. This provides a foundation for the drill bit 2 to drive the cutter blade 3 to drill the geological soil. After drilling through hard soil and rock is completed, the friction force on the friction plate 22 decreases, and the tension force on the tension spring 19 decreases accordingly. The tension spring 19 releases its potential energy, and through the transmission block 18 and the first arc rod 21, pulls the friction plate 22 back to its original position for easy use next time. The guide block 24 is designed so that when soil and rock enter the device slot, the inclined surface of the guide block 24 can more easily discharge the soil and rock by gravity along the inclined surface, avoiding soil accumulation inside the device slot. When the drill rod 1 and drill bit 2 are removed, the drill bit 2 will loosen the soil and rock, causing soil and rock to accumulate on the surface of the drill bit 2, increasing the weight of the drill bit 2. This means that if the connection between the drill bit 2 and the drill rod 1 is broken, each increase in the weight of the drill bit 2 may lead to... Increased pressure on the clamping mechanism may prevent it from effectively clamping the drill bit 2. To avoid this, in this embodiment of the invention, when the drill rod 1 and drill bit 2 are inserted into the geological soil, a delay mechanism first adheres to the compaction mechanism, which then moves closer to the drill rod 1. This compaction mechanism then drives the friction roller 26 closer to the drill rod 1. At this point, the friction roller 26 is closer to the center point of the drill rod 1 than the cutter blade 3. When the drill rod 1 and drill bit 2 are inserted into the geological soil, the delay mechanism stops adhering to the compaction mechanism. The compaction mechanism then drives the friction roller 26 further away from the center point of the drill rod 1 than the cutter blade 3. As the drill rod 1 moves downward, the friction roller 26 rotates along the inner wall of the borehole soil, compacting the soil. When the drill rod 1 and drill bit 2 rise and return to their original position...The friction roller 26 compacts the soil in the borehole a second time. During this time, the blades 3 on the surface of the drill bit 2 cannot contact the inner wall of the soil, effectively preventing the drill bit 2 from loosening the soil and causing soil accumulation on its surface, increasing the weight of the drill bit 2. To achieve soil compaction, initially, the friction roller 26 is pushed close to the drill rod 1. The drill rod 1 then moves the extrusion block 29 via the connecting rod. The movement of the extrusion block 29 compresses the second compression spring 30, causing it to deform and generate elastic potential energy. At this time, the delay mechanism operates, and the connecting rod is affected by the delay mechanism, causing the friction roller 26 to be closer to the center point of the drill rod 1 than the blades 3. When the drill rod 1 and drill bit 2 are deeply embedded in the soil… The delay mechanism's influence on the connecting rod ends, and the second compression spring 30 instantly releases its elastic potential energy, driving the connecting rod to reset via the squeezing block 29. This reset of the connecting rod, in turn, drives the friction roller 26 to reset. At this point, the friction roller 26 is farther from the center point of the drill rod 1 than the cutter blade 3. As the drill rod 1 and drill bit 2 continue to move into the soil, the friction roller 26 can squeeze and rotate along the inner wall of the soil, thus compacting the soil and preventing it from loosening. When the drill rod 1 and drill bit 2 are removed, the friction roller 26 moves again along the inner wall of the soil for secondary compaction, effectively tamping the soil. If, in the initial state, the friction roller 26 is farther from the center point of the cutter blade 3 than the cutter blade 3, when the drill rod 1 rotates, the friction roller 26... This will cause the friction roller 26 to contact the soil before the blade 3. The hardness of the soil may hinder the lateral rotation of the friction roller 26, leading to its breakage. To solve this problem, in this embodiment of the invention, the first hook and loop fastener 34 is first attached to the surface of the second hook and loop fastener 35. It should be noted that the ends of the first hook and loop fastener 34 and the second hook and loop fastener 35 that are opposite to each other have greater adhesion. At this time, the first hook and loop fastener 34 drives the connecting ring 31 to move towards the drill rod 1 through the fixed square rod 32. The connecting ring 31 then drives the friction roller 26 to move through the connecting rod, and at the same time drives the extrusion block 29 to compress the second compression spring 30, causing the second compression spring 30 to deform and generate elastic potential energy. At this time, when the drill rod 1 and the drill bit 2 rotate again, the friction roller 26 will be able to rotate. The friction roller 26 makes slight contact with hard soil, effectively preventing damage. Over time, the adhesion between the first hook and loop fastener 34 and the second hook and loop fastener 35 gradually becomes insufficient to overcome the elastic potential energy of the second compression spring 30, causing them to separate. The second compression spring 30 then drives the friction roller 26 to move away from the drill rod 1. At this point, when the friction roller 26 rotates laterally, it contacts the soil loosened by the rotation of the cutter blade 3, significantly reducing its hardness and minimizing damage to the friction roller 26. Because the adhesion between the first hook and loop fastener 34 and the second hook and loop fastener 35 may decrease due to contact with the soil, they can be replaced after each work session.
