DETAILED DESCRIPTION

[0015] In order to make the purpose, technical scheme and advantages of the application more clear and understandable, the application is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the application and do not limit the application.

[0016] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 and Figure 10 , the application provides a drilling device with cooling effect during mineral exploitation, which comprises a branch pipe 1, an extension pipe 2, a connecting pipe 3 and a drill bit 4, the connecting pipe 3 is threadedly connected between the branch pipe 1 and the extension pipe 2, the drill bit 4 is fixedly connected at the bottom end of the branch pipe 1, and three groups of drill teeth 41 are detachably arranged on the drill bit 4; A first spiral heat dissipation pipe 11 with a spiral structure is fixedly installed on the inner wall of the branch pipe 1. The first spiral heat dissipation pipe 11 is equidistantly arranged along the circumference of the inner wall of the branch pipe 1. The bottom end of the first spiral heat dissipation pipe 11 is fixedly connected to a liquid guide pipe 7 that extends into the drill bit 4. One end of the liquid guide pipe 7 is fixedly connected to a second spiral heat dissipation pipe 71 with a spiral structure that is inserted into the drill tooth 41. The connecting pipe 3 is equipped with a regulating mechanism for adjusting the connection between the first spiral heat dissipation pipe 11 and the branch pipe 1.

[0017] In this case, the length of the extension pipe 2 is determined according to the actual use. It can be a combination of multiple pipes to form a long pipe. The branch pipe 1 is the pipe connected to the drill bit 4, and its length is controlled within two meters. The length of the branch pipe 1 can also be determined according to the actual situation. It is located at the head of the drill hole. During the drilling process, the branch pipe 1 will also generate heat. The purpose of setting the drill bit 4 and the branch pipe 1 as one unit is to increase stability and prevent loosening between the drill bit 4 and the branch pipe 1 during the drilling process. At the same time, a connecting pipe 3 is set between the branch pipe 1 and the extension pipe 2. The connecting pipe 3 is connected to the branch pipe 1 and the extension pipe 2 by a threaded connection. When not in use, the connecting pipe 3 can be easily disassembled. The connecting pipe 3 is equipped with a control mechanism to adjust the connection state between the connecting pipe 3 and the branch pipe 1. It can control the flow direction of water in the branch pipe 1 and can be adjusted according to different usage sites to reduce the temperature of the drill bit 4 while saving water resources.

[0018] Ways to save water resources: 1. When drilling into the rock using drill bit 4, strong friction will occur between drill bit 4 and the rock. At this time, the water flow can be controlled by the regulating mechanism to flow from the branch pipe 1 at the same time. Simultaneously, the water can flow through the first spiral heat dissipation pipe 11. Through the bidirectional water flow, the heat dissipation efficiency of drill bit 4 can be accelerated, avoiding damage to drill bit 4 due to excessive heat and extending its service life.

[0019] 2. When drilling into the soil using drill bit 4, the friction between drill bit 4 and soil is less than that between drill bit 4 and rock. Therefore, drill bit 4 does not generate a lot of heat, so there is no need to pass a lot of water to cool it down. At this time, the water is controlled by the regulating mechanism to pass through the first spiral heat dissipation pipe 11 and then enter the second spiral heat dissipation pipe 71 to cool the drill bit 4. There is no need to discharge a large amount of water through the branch pipe 1, thus saving water resources.

[0020] 3. When drilling into soil and rock using drill bit 4, due to the uncertainty of the area to be drilled, there may be a situation where the surface is soil and the underlying layer is rock. When drilling into soil, water is cooled by the first spiral heat dissipation pipe 11. After drilling into rock, the water flows in both directions to efficiently cool the drill bit 4.

[0021] The above three methods are the situations encountered in drilling. By using the control mechanism in conjunction with the first spiral heat dissipation pipe 11, water resources can be effectively saved, and the heat-generating area during the drilling process can be efficiently dissipated, resulting in a good cooling effect.

[0022] The first spiral heat dissipation pipe 11 is arranged along the inner wall of the branch pipe 1, such as... Figure 3 As shown, the state of the first spiral heat dissipation pipe 11 can be seen. Its circumference is equidistant and can be superimposed to form a cylindrical structure with a channel in the middle. Therefore, the water flow in the first spiral heat dissipation pipe 11 can effectively cool down the branch pipe 1 and reduce the heat generated on the branch pipe 1. The water in the first spiral heat dissipation pipe 11 can enter the drill bit 41 through the liquid guide pipe 7 and the second spiral heat dissipation pipe 71 to cool down the drill bit 41. This achieves efficient cooling of the heat-generating area during drilling and can simultaneously cool down the branch pipe 1, the drill bit 4, and the drill bit 41, thereby increasing the cooling range and preventing deformation and wear of the branch pipe 1 due to the inability to dissipate heat after long-term use. This extends the service life and prevents deviation during drilling.

[0023] The advantages of using a spiral structure for the first spiral heat pipe 11 are as follows: The spiral structure guides the water flow to form an orderly vortex, avoiding turbulence and local impact. It also lengthens the water flow channel within a limited space, increasing the contact time between the cooling water and the heated cutting part, resulting in more thorough heat exchange. At the same time, it forms a three-dimensional cooling channel that can cover the circumference of the heated area of ​​drill bit 4, preventing local overheating and improving the cooling effect. Therefore, the spiral structure can effectively improve the cooling effect on drill bit 4 and increase the strength of the inner wall of branch pipe 1, avoiding direct impact of water flow and extending service life.

[0024] By setting the first spiral heat dissipation pipe 11 and the control mechanism, water resources can be effectively saved, and the circumference of the heat-generating area of ​​the drill bit 4 can be covered to avoid local overheating and improve the cooling effect. At the same time, the impact resistance of the branch pipe 1 can be increased. While reducing the temperature of the heat-generating area of ​​the drill bit 4, the heat generated at the branch pipe 1 can also be reduced to prevent deformation.

[0025] Among them, such as Figure 9 and Figure 10 The diagram shows the structure of the drill bit 4 and the drill teeth 41. The drill teeth 41 are detachably mounted on the drill bit 4, and the three drill teeth 41 have multiple sets of protruding teeth around their periphery. This is existing technology. The connection structure between the drill teeth 41 and the drill bit 4 is also existing technology, so it will not be described in detail. A nozzle is provided at the end of the drill teeth 41, and the cooling water that enters the drill teeth 41 can be sprayed out through the nozzle.

[0026] Among them, such as Figure 9As shown, a spray hole 42 is provided on the drill bit 4. The water outlet end of the spray hole 42 is located between the protruding teeth 41, and the spray hole 42 of the drill bit 4 has an arc-shaped structure to facilitate the complete discharge of water and prevent it from remaining inside the drill bit 4. Figure 9 It can also be seen that the drill bit 4 has a through hole that matches the fluid guide tube 7, which corresponds to the drill tooth 41.

[0027] The control mechanism includes a liquid distribution sleeve 31 and a liquid guiding ring 32. The liquid distribution sleeve 31 is fixedly connected to the inner wall of the connecting pipe 3, and the liquid guiding ring 32 is fixedly connected to the top surface of the liquid distribution sleeve 31. The top surface of the liquid guiding ring 32 is inclined, and a conductive insertion tube 33 is provided on the liquid guiding ring 32 corresponding to the top surface of the first spiral heat dissipation pipe 11.

[0028] The liquid guiding ring 32 is used to guide the water entering the connecting pipe 3 downwards. A connecting tube 33 corresponding to the first spiral heat dissipation tube 11 is provided on the liquid guiding ring 32. After the connecting pipe 3 is threaded to the top periphery of the branch pipe 1, the connecting tube 33 is aligned with the top of the first spiral heat dissipation tube 11. Pressing the connecting tube 33 at this time can insert the connecting tube 33 into the first spiral heat dissipation tube 11, so that the connecting tube 33 is connected to the first spiral heat dissipation tube 11. When water is introduced from the top of the extension pipe 2, the water can flow directly downwards from the branch pipe 1, and can also be introduced into the first spiral heat dissipation tube 11 through the connecting tube 33. The dual-channel flow of water can effectively improve the cooling effect.

[0029] Supplement: The separatory sleeve 31 can be threaded into the connecting tube 3, which makes it easy to remove the separatory sleeve 31.

[0030] Example 2: Please refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the other parts of this embodiment are the same as those of embodiment 1. The difference is that a liquid distribution plate 5 that slides up and down is provided on the top surface of the liquid distribution sleeve 31.

[0031] The control mechanism also includes a dispensing plate 5 set on the top surface of the dispensing sleeve 31, a support component for supporting the dispensing plate 5, and a driving component for driving the dispensing plate 5 to move up and down. The dispensing plate 5 has a conical structure with an arc-shaped top.

[0032] The supporting components include a connecting block 51, a sealing cylinder 511, a threaded rod 6, and a second gear 61. The connecting block 51 is fixedly connected to the periphery of the separating plate 5, and the connecting blocks 51 are equidistantly arranged along the periphery of the separating plate 5. The connecting blocks 51 are arranged between the connecting tubes 33. The sealing cylinder 511 is slidably inserted into the separating sleeve 31 and the liquid guiding ring 32. The top end of the sealing cylinder 511 is fixedly connected to the connecting block 51, and the bottom end is threadedly connected to the periphery of the threaded rod 6. The bottom end of the threaded rod 6 is fixedly connected to the second gear 61, and the second gear 61 is rotatably arranged in the separating sleeve 31.

[0033] The driving components include a gear sleeve 34, a motor 35, and a first gear 36. The periphery of the liquid separating sleeve 31 is provided with an annular groove 37 for the gear sleeve 34 to rotate. The gear sleeve 34 is meshed with the second gear 61. The motor 35 is fixedly installed inside the liquid separating sleeve 31. The power output end of the motor 35 is fixedly connected to the first gear 36, and the first gear 36 is meshed with the gear sleeve 34.

[0034] The separator 5 is used to direct the water introduced into the connecting pipe 3 to the surrounding area. Its purpose is to connect the branch pipe 1 and the first spiral heat dissipation pipe 11. It operates in two states: The first method involves placing the bottom of the liquid distribution plate 5 against the top surface of the liquid distribution sleeve 31. In this case, the liquid distribution plate 5 can block the connection between the connecting pipe 3 and the branch pipe 1, preventing water flowing down from the connecting pipe 3 from entering the branch pipe 1. This allows the water to flow around the liquid distribution plate 5 and into the conductive tube 33, where it flows into the first spiral heat dissipation pipe 11. This method is suitable for dissipating heat from the drill bit 4 when drilling into the soil, saving water resources and preventing large amounts of water from flowing downward through the branch pipe 1.

[0035] The second method involves starting the motor 35, which drives the first gear 36 to rotate. The first gear 36 then drives the gear sleeve 34 to rotate, which in turn drives the second gear 61 to rotate. The second gear 61 then drives the threaded rod 6 to rotate, which in turn drives the sealing cylinder 511 to move upward. The sealing cylinder 511 then drives the connecting block 51 to move upward, causing the liquid distribution plate 5 to move upward. This allows the connecting pipe 3 to connect with the branch pipe 1, enabling water to flow out of the drill bit 4 through the branch pipe 1 and also through the first spiral heat dissipation pipe 11 from the drill teeth 41, thus cooling the drill bit 4 in both directions. This method is suitable for use in areas where the upper layer is soil and the lower layer is rock. It allows for switching the water flow rate and the degree of cooling, thus expanding the applicability range.

[0036] Example 3: Please refer to Figure 11 and Figure 12 As shown, the other parts of this embodiment are the same as those of Embodiment 1. The difference is that a conduit 211 is connected to the conductive tube 33 to separately introduce cooled water into the first spiral heat dissipation tube 11.

[0037] The control mechanism also includes a conduit 211, a connecting component for the extension tube 2, and a cooling and conductive component for the conduit 211. The bottom end of the conduit 211 is threadedly connected to the connecting insertion tube 33, and the top end is threadedly connected to the connecting component. The connecting component is threadedly connected to the top end of the extension tube 2.

[0038] The connecting components include a fixed plate 21 and a second liquid inlet pipe 22. The fixed plate 21 is threaded to the outer periphery of the top end of the extension pipe 2, and the second liquid inlet pipe 22 is fixedly connected to the axis of the fixed plate 21.

[0039] The cooling conduction component includes a collar 212 and a rotating plate 213. The collar 212 is fixedly connected to the top surface of the fixed plate 21, and the rotating plate 213 is rotatably connected between the top surface of the collar 212 and the second liquid inlet pipe 22. The space enclosed by the collar 212, the rotating plate 213 and the second liquid inlet pipe 22 is a coolant distribution chamber. The top surface of the rotating plate 213 is fixedly provided with a first liquid inlet pipe 214 that communicates with the coolant distribution chamber.

[0040] The conduit 211 is used to transport coolant, which is delivered separately to the first spiral heat dissipation pipe 11 to efficiently cool the drill bit 4. Under high-intensity drilling operations, the conduit 211 can efficiently and quickly reduce the temperature generated at the drill bit 4, thereby improving work efficiency.

[0041] The second inlet pipe 22 is used to connect to an external water source. When the extension pipe 2 is in a rotating state, the external water source is connected through the second inlet pipe 22, allowing water to be introduced into the extension pipe 2. Then, the water is discharged from the drill bit 4 through the branch pipe 1. The external cooling water source is then connected through the first inlet pipe 214, allowing the cooling water to be introduced into the coolant distribution chamber. The water then enters the first spiral heat dissipation pipe 11 through the conduit 211, and finally enters the drill bit 41 to efficiently dissipate heat from the drill bit. Finally, the water is sprayed out through the nozzle.

[0042] The purpose of using the rotating plate 213 is to facilitate the introduction of coolant into the coolant distribution chamber when the extension pipe 2 is in a rotating state. The coolant entering the coolant distribution chamber can then enter the conduit 211 to achieve efficient cooling of the drill bit 4 and drill teeth 41.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
