Description

Technical Field

[0001] This invention relates to the field of soil pollution remediation technology, specifically to a soil pollution control and remediation device for piling engineering. Background Technology

[0002] With the rapid advancement of industrialization and urbanization, soil pollution has become increasingly prominent, becoming a significant factor restricting the sustainable development of the ecological environment. In piling operations in fields such as building construction and municipal engineering, secondary soil pollution or exacerbation of existing pollution can easily occur due to mechanical disturbance and the migration of underground pollutants. Therefore, carrying out soil pollution control and remediation simultaneously during piling has become an important research direction in the field of soil pollution remediation technology. How to achieve efficient synergy between piling operations and pollution remediation, reduce the risk of pollution spread, and improve the accuracy and efficiency of remediation are key issues that urgently need to be addressed in this field.

[0003] Existing technologies include several control and remediation techniques. For example, some projects employ in-situ remediation technology, which attempts to degrade, transform, and absorb pollutants in the soil by applying remediation agents to deeply contaminated soil. However, soil pollution remediation equipment for piling projects often suffers from limitations such as single functionality and insufficient synergy. For instance, some equipment can only perform piling and cannot simultaneously carry out pollution remediation, requiring additional remediation work after piling is completed. This not only increases the construction period and cost but may also lead to an expansion of the pollutant diffusion range due to the time interval. Other equipment, while possessing preliminary remediation capabilities, suffers from poor precision in agent delivery, making it difficult to flexibly adjust the agent spraying position according to the drilling depth, which can easily lead to agent waste and uneven remediation effects.

[0004] The equipment cannot effectively synchronize piling and chemical spraying, cannot improve operating efficiency through simultaneous water spraying and residue cleaning, and cannot effectively control the spraying position based on the drilling depth to reduce waste and improve treatment efficiency. Therefore, we propose a soil pollution control and treatment device for piling projects. Summary of the Invention

[0005] The purpose of this invention is to provide a soil pollution control and treatment device for piling projects, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A soil pollution control and remediation device for piling projects includes a vehicle body. A hydraulic cylinder fixed end is hingedly mounted on the vehicle body, and the piston end of the hydraulic cylinder is hingedly mounted on a swing frame. One end of the swing frame is hingedly mounted on one end of the vehicle body. A remediation component is provided on the swing frame, and the remediation component includes:

[0008] An asynchronous motor is fixedly installed at one end of the swing frame near the hydraulic cylinder. A threaded rod is fixedly installed at the output end of the asynchronous motor. Both ends of the threaded rod are rotatably installed inside the swing frame through bearing components. A movable frame is threadedly fitted on the threaded rod. A slider is fixedly installed on the outside of the movable frame. The slider is slidably installed inside the slide rail. The slide rail is fixedly installed on the outer wall of the swing frame.

[0009] An asynchronous motor is fixedly installed on the outer wall of the moving frame. A rotating shaft is fixedly installed on the output end of the asynchronous motor. A drill rod is rotatably installed inside the moving frame through a sealed bearing. A transmission component is installed between the rotating shaft and the drill rod. A through hole is opened on the arc-shaped side wall of the drill rod. A cavity is opened inside the moving frame. The through hole, the cavity and the center of the drill rod are connected.

[0010] A rotating drum is fixedly installed on the outer wall of the movable frame at the end away from the asynchronous motor. Inside the rotating drum, one end of a rotating rod is rotatably installed via bearing components. A rectangular plate is fixedly installed on the other end of the rotating rod. A medicine tank is fixedly installed on one side of the rectangular plate. A water pump input end is fixedly installed on the medicine tank. One end of a bent pipe is fixedly installed inside the movable frame. The bent pipe is connected to the cavity. A shut-off solenoid valve is installed on the bent pipe. A flexible hose is fixedly installed between the other end of the bent pipe and the water pump output end. A conical cover with a large end is fixedly installed at the end of the drill rod away from the movable frame. The conical cover with a through opening is provided at its small end.

[0011] In a further embodiment, a support frame is fixedly installed at one end of the vehicle body away from the hydraulic cylinder, and the other end of the swing frame is attached to the top of the support frame, which can support the swing frame in a horizontal state.

[0012] In a further embodiment, a bracket is fixedly installed on the outer wall of the mobile frame, and the drill rod is rotatably mounted inside the center of the bracket via a bearing component, making the rotation of the drill rod more stable.

[0013] In a further embodiment, two sets of sliders and slide rails are provided, and the two sets of sliders and slide rails are mirror images of each other on both sides of the movable frame. Multiple sets of through holes are provided, and the multiple sets of through holes are arranged in a circular array with the center of the circular cross-section of the drill rod as the array center, and are equally spaced.

[0014] In a further embodiment, an auxiliary component is provided on the outside of the drill rod. The auxiliary component includes a clean water tank. A clean water tank is fixedly installed on the other side of the rectangular plate. Both the clean water tank and the chemical tank are provided with liquid inlets. The clean water tank and the chemical tank are filled with clean water and chemical solution, respectively. Two sets of water pumps, bends, hoses, and shut-off solenoid valves are provided, and the two water pumps are respectively installed on the clean water tank and the chemical tank, so that the drilling process is smoother or cleaning is performed.

[0015] In a further embodiment, a counterweight is fixedly installed at the center of the end of the rectangular plate away from the water pump. A through-hole is provided on the arc-shaped sidewall of the rotating drum. Two sets of the through-hole are provided, and the two sets of the through-hole are perpendicular to each other. A pin is fitted inside the through-hole and passes through the rotating rod, so that the clean water tank and the medicine tank remain stable when they are in a horizontal state at the target position.

[0016] In a further embodiment, the swing frame is also equipped with an efficiency-enhancing component, which includes a fixing block. The fixing block is fixedly installed on the side of the swing frame away from the asynchronous motor. One end of a cylinder is rotatably installed inside the fixing block via a bearing. The other end of the cylinder is fitted inside the drill rod. A locking block is fixedly installed on the arc-shaped outer wall of the cylinder. A locking groove is opened on the arc-shaped side wall of the drill rod. The locking block slides and fits inside the locking groove, so that the drill rod drives the cylinder to rotate, and the drill rod can slide outside the cylinder.

[0017] In a further embodiment, the cylindrical arc-shaped sidewall has a through side groove that communicates with the cavity. A bottom one-way valve is installed inside the end of the cylinder away from the fixed block. A side pipe is fixedly installed on the side of the drill rod away from the side groove.

[0019] In a further embodiment, a connecting pipe is fixedly installed inside the L-shaped plate, and a main airbag and a secondary airbag are fixedly installed at both ends of the connecting pipe, respectively. The main airbag is located inside the frame, and the secondary airbag is located inside the cylinder. The connecting pipe passes through the side groove, thereby preventing external impurities from entering the cylinder and playing a protective role.

[0020] Compared with the prior art, the present invention provides a soil pollution control and treatment device for piling engineering, which has the following beneficial effects:

[0021] 1. The soil pollution control and remediation equipment used in this piling project, to better control and remediate soil pollution during the piling process, incorporates remediation components. When the hydraulic cylinder on the vehicle is activated, the swing frame moves from a horizontal to a vertical position. The support frame supports the horizontally positioned swing frame. When the asynchronous motor is activated, the threaded rod rotates, allowing the moving frame to move axially, causing the slider to slide synchronously on the slide rail. During the vertical downward movement of the moving frame, the asynchronous motor is activated, causing the rotating shaft to rotate. This, combined with the transmission components, causes the drill rod to move along the support... The frame rotates inside to perform drilling and pile driving. When the water pump on the chemical tank and the shut-off solenoid valve on the bend are activated, the chemical solution enters the bend through the hose, then enters the drill rod through the cavity and through the hole, and finally is sprayed into the soil at the drilling point through the small end opening of the conical cover. This degrades, transforms, and absorbs pollutants in the soil, thereby better controlling and treating soil pollution during the pile driving process. When the swing frame moves, the rotating rod rotates synchronously inside the rotating cylinder. Using the weight of the chemical solution, the rectangular plate keeps the chemical tank in a vertical position, preventing chemical leakage.

[0022] 2. The soil pollution control and remediation equipment used in this piling project incorporates auxiliary components to ensure better operation of the remediation components. When the water pump on the clean water tank and the corresponding shut-off solenoid valve on the bend are activated, clean water is sprayed simultaneously during drilling and piling, making the drilling process smoother. After piling is completed, only clean water is sprayed, without any chemicals, thus cleaning residues inside the drill rod and other structures, improving operational efficiency. The inlet facilitates the addition of chemicals and clean water, and the counterweight helps maintain the horizontal position of the chemical and clean water tanks during the swing frame's rotation. Inserting a pin into the limiting hole ensures the stability of the chemical and clean water tanks at the target horizontal position, preventing them from wobbling due to external forces. In summary, this allows the remediation components to operate more effectively.

[0023] 3. The soil pollution control and remediation equipment used in this piling project, in order to improve remediation efficiency and save costs, incorporates an efficiency-enhancing component. When the drill rod moves or rotates axially, the locking block slides synchronously axially within the locking groove, and drives the cylinder to rotate within the fixed block. When the drill rod just slides downward outside the cylinder, the side groove is always connected to the through hole and cavity, so the chemical or clean water in the remediation component can always be injected into the drill rod through the bottom one-way valve. However, the cylinder will block the side pipe. Only when the drill rod continues to penetrate deeper into the soil borehole, the side pipes on the vertical drill rod pass over the bottom of the cylinder in sequence, so that the cylinder no longer blocks the side pipes on the drill rod in sequence. Thus, the chemical or clean water can be sprayed out from the unblocked side pipes, which avoids waste of chemical or clean water, saves costs, and allows the chemical to enter the soil at different depths, improving remediation efficiency. The sprayed high-pressure water can prevent soil from entering the conical hood or side pipe in reverse, and the filter plate can further prevent impurities from entering the side pipe.

[0024] 4. The soil pollution control and treatment equipment used in this piling project has been improved in terms of practicality by setting up protective components. The L-shaped plate is installed on the drill rod with the clamps. The threaded column on the frame is rotated, which causes the circular plate to squeeze the main air bladder. The gas inside the main air bladder is then injected into the secondary air bladder through the connecting pipe. This causes the secondary air bladder to expand and fit tightly against the inside of the cylinder, thus preventing external impurities from entering the cylinder and providing protection. The overall equipment is more practical. Attached Figure Description

[0045] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] In this application, the term "above" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0047] Please see Figures 1-14 The present invention provides a technical solution:

[0048] A soil pollution control and treatment device for piling projects includes a vehicle body 1. A hydraulic cylinder 2 is hinged to the fixed end of the vehicle body 1. The piston end of the hydraulic cylinder 2 is hinged to the swing frame 3. One end of the swing frame 3 is hinged to one end of the vehicle body 1. In addition, a support frame 4 is fixedly installed at the end of the vehicle body 1 away from the hydraulic cylinder 2. The other end of the swing frame 3 is attached to the top of the support frame 4. The support frame 4 can support the swing frame 3 in a horizontal state.

[0049] Specifically, the hydraulic cylinder 2 on the vehicle body 1 is activated. The piston end of the hydraulic cylinder 2 extends and pushes the swing frame 3, causing it to slowly rotate from a horizontal state to a vertical state around the hinge point with the vehicle body 1. The support frame 4 can support the horizontal swing frame 3 and provide it with support, preventing the swing frame 3 from swaying or falling unnecessarily due to its own weight.

[0050] In one embodiment of the present invention, a control component 5 is provided on the swing frame 3. The control component 5 includes an asynchronous motor 51. The asynchronous motor 51 is fixedly installed at one end of the swing frame 3 near the hydraulic cylinder 2. A threaded rod 52 is fixedly installed at the output end of the asynchronous motor 51. The two ends of the threaded rod 52 are rotatably installed inside the swing frame 3 through bearing components. A movable frame 53 is threadedly engaged on the threaded rod 52. A slider 54 is fixedly installed on the outside of the movable frame 53. The slider 54 is slidably installed inside the slide rail 55. The slide rail 55 is fixedly installed on the outer wall of the swing frame 3. In addition, the slider 54 and the slide rail 55 are provided with Two sets of sliders 54 and slide rails 55 are mirror images of each other on both sides of the movable frame 53. An asynchronous motor 56 is fixedly mounted on the outer wall of the movable frame 53, and a rotating shaft 57 is fixedly mounted on the output end of the asynchronous motor 56. In addition, a bracket 58 is fixedly mounted on the outer wall of the movable frame 53. The drill rod 59 is rotatably mounted inside the center of the bracket 58 through a bearing, making the rotation of the drill rod 59 more stable. The drill rod 59 is rotatably mounted inside the movable frame 53 through a sealed bearing. A transmission component 591 is installed between the rotating shaft 57 and the drill rod 59. The transmission component 591 includes two parts respectively fixedly mounted on the rotating shaft. The transmission sprockets and transmission chains outside the drill rod 57 and drill rod 59 are connected. The drill rod 59 has through holes 510 on its arc-shaped sidewall. Multiple sets of through holes 510 are arranged in a circular array with equal spacing around the center of the circular cross-section of the drill rod 59. A cavity 511 is formed inside the moving frame 53. The through holes 510, the cavity 511, and the center of the drill rod 59 are connected. A rotating cylinder 512 is fixedly installed on the outer wall of the moving frame 53 at the end furthest from the asynchronous motor 56. A rotating rod 513 is rotatably mounted inside the rotating cylinder 512 via bearings. 3. A rectangular plate 514 is fixedly installed at the other end. A medicine tank 515 is fixedly installed on one side of the rectangular plate 514. A water pump 516 input end is fixedly installed on the medicine tank 515. One end of a bent pipe 517 is fixedly installed inside the movable frame 53. The bent pipe 517 is connected to the inside of the cavity 511. A shut-off solenoid valve 519 is installed on the bent pipe 517. A hose 518 is fixedly installed between the other end of the bent pipe 517 and the output end of the water pump 516. A conical cover 520 large end is fixedly installed at the end of the drill rod 59 away from the movable frame 53. A through opening is provided at the small end of the conical cover 520.

[0051] In this embodiment, when the swing frame 3 is in a vertical position, the asynchronous motor 51 is started. The output shaft of the asynchronous motor 51 drives the threaded rod 52 to rotate at a stable speed. Since the threaded rod 52 is threadedly engaged with the moving frame 53, the rotation of the threaded rod 52 is converted into the movement of the moving frame 53 along the axial direction of the threaded rod 52. At the same time, the slider 54 outside the moving frame 53 slides synchronously inside the slide rail 55. The slide rail 55 guides and limits the slider 54, ensuring that the movement of the moving frame 53 is smooth and does not deviate from the direction. During the vertical downward movement of the moving frame 53, the asynchronous motor 56 is started synchronously. The output end of the asynchronous motor 56 drives the rotating shaft 57 to rotate. The rotating shaft 57 is connected to the transmission component 591 (composed of two separately fixed components). The drive sprocket (fixed on the outside of the rotating shaft 57 and the drill rod 59) and the drive chain (fitted around the outside of both) transmit power to the drill rod 59, causing the drill rod 59 to rotate stably inside the support 58, thereby penetrating the soil for drilling and piling operations. After the drill rod 59 enters the soil, the water pump 516 on the chemical tank 515 and the shut-off solenoid valve 519 on the bend 517 are activated. The chemical solution in the chemical tank 515 is then transported to the inside of the bend 517 through the hose 518 under the action of the water pump 516. Subsequently, it enters the inside of the drill rod 59 through the cavity 511 and multiple sets of through holes 510, and finally sprays into the soil at the drilling point through the opening at the small end of the conical cover 520, thereby efficiently degrading, transforming and absorbing pollutants in the soil during the piling process.

[0052] Specifically, common treatments include chelating agents for heavy metal pollution and biodegradable agents for organic pollution. Their remediation mechanisms are as follows: If the soil is contaminated with heavy metals (such as lead, cadmium, and copper), the treatment contains chelating agents such as ethylenediaminetetraacetic acid (EDTA) and diethyltriaminepentaacetic acid (DTPA). After being sprayed into the soil through the drill rod 59 and cone shroud 520, the chelating agent molecules will undergo a coordination reaction with the heavy metal ions in the soil, forming stable water-soluble chelates. These chelates can move with soil moisture, preventing heavy metal ions from being fixed in the soil or absorbed by plants. Subsequently, they can be removed from the soil through other auxiliary means (such as leaching), reducing the heavy metal content in the soil. When the soil contains organic pollution (such as petroleum hydrocarbons and polycyclic aromatic hydrocarbons), the treatment contains... Microbial agents (such as Pseudomonas and Bacillus) and nutrients (such as nitrogen, phosphorus, and potassium) are used in the soil. After being sprayed into the soil, the microbial agents use organic pollutants as a carbon source and energy source for metabolic activities, while the nutrients provide sufficient nutrients for the growth and reproduction of microorganisms, promoting their proliferation. Under the action of microorganisms, organic pollutants are gradually decomposed into harmless carbon dioxide and water, or transformed into other non-toxic small molecules, thereby eliminating organic pollution in the soil. In addition, some pesticide solutions contain suspensions of adsorbent materials (such as activated carbon and zeolite). When the pesticide solution is sprayed into the soil, the adsorbent materials will undergo physical or chemical adsorption with the pollutants in the soil, firmly adsorbing the pollutants onto their surface, reducing the mobility and bioavailability of pollutants in the soil, and reducing harm to the surrounding environment and organisms.

[0053] Furthermore, when the swing frame 3 moves, the rotating rod 513 will rotate synchronously inside the rotating cylinder 512 with the movement of the swing frame 3. Utilizing the weight of the medicine itself, the rectangular plate 514 will generate a balancing torque, which will keep the medicine tank 515 in a vertical position, effectively preventing the medicine from leaking out due to the tilt of the tank.

[0054] In one embodiment of the present invention, an auxiliary component 6 is provided on the outside of the drill rod 59. The auxiliary component 6 includes a clean water tank 61. The clean water tank 61 is fixedly installed on the other side of the rectangular plate 514. Both the clean water tank 61 and the chemical tank 515 are provided with inlets 62. The clean water tank 61 and the chemical tank 515 are respectively filled with clean water and chemical solution. Two sets of water pumps 516, bends 517, hoses 518 and shut-off solenoid valves 519 are provided, and the two water pumps 516 are respectively located in the clean water tank 61 and the chemical tank 61. On the barrel 515, to make the drilling process smoother or to clean, in addition, a counterweight 63 is fixedly installed at the center of the end of the rectangular plate 514 away from the water pump 516. A through limiting hole 64 is opened on the arc-shaped side wall of the rotating cylinder 512. There are two sets of limiting holes 64, and the two sets of limiting holes 64 are in a vertical state. A pin 65 is sleeved inside the limiting hole 64. The pin 65 passes through the rotating rod 513, so that the clean water barrel 61 and the medicine barrel 515 remain stable when they are in a horizontal state at the target position.

[0055] In this embodiment, when the water pump 516 on the clean water tank 61 and the corresponding shut-off solenoid valve 519 on the bend 517 are activated, the clean water in the clean water tank 61 will be transported to the drill rod 59 through another set of water pumps 516, hoses 518, bends 517, and other structures. It will be sprayed out simultaneously during the drilling and pile driving process. The clean water can moisten the soil, reduce its hardness and friction, and make the drilling process smoother. Simultaneously, after pile driving is completed, the water pump 516 and shut-off solenoid valve 519 corresponding to the chemical tank 515 can be closed, and only clean water will be sprayed out. The clean water can flush out any residual chemicals inside the drill rod 59, through hole 510, cavity 511, and other structures, improving the cleaning effect. To improve the efficiency of subsequent operations, the inlet 62 on the clean water tank 61 and the medicine tank 515 allows operators to add medicine and clean water at any time. The counterweight 63 at the center of the end of the rectangular plate 514 away from the water pump 516 increases the weight of that end of the rectangular plate 514, making the medicine tank 515 and the clean water tank 61 better maintain a horizontal state during the rotation of the swing frame 3. The two sets of vertical limiting holes 64 opened on the arc-shaped side wall of the rotating cylinder 512 can firmly fix the medicine tank 515 and the clean water tank 61 when they are in the target horizontal position by inserting the pin 65 into the limiting hole 64 and through the rotating rod 513, thus preventing them from shaking due to external forces.

[0056] In one embodiment of the present invention, the swing frame 3 is further provided with an efficiency-enhancing component 7, which includes a fixing block 71. The fixing block 71 is fixedly installed on the side of the swing frame 3 away from the asynchronous motor 51. One end of a cylinder 72 is rotatably installed inside the fixing block 71 via a bearing. The other end of the cylinder 72 is fitted inside the drill rod 59. A locking block 73 is fixedly installed on the arc-shaped outer wall of the cylinder 72. A slot 74 is opened on the arc-shaped side wall of the drill rod 59. The locking block 73 slides and fits inside the slot 74, so that the drill rod 59 drives the cylinder 72 to rotate. The drill rod 59 can slide outside the cylinder 72. In addition, the arc-shaped side wall of the cylinder 72 has a through side groove 75, which is connected to the cavity 511. A bottom one-way valve 76 is provided inside the end of the cylinder 72 away from the fixed block 71. A side tube 77 is fixedly installed on the side of the drill rod 59 away from the side groove 75. A filter plate 78 is fixedly installed inside the side tube 77. There are multiple sets of side tubes 77 and filter plates 78, and the multiple sets of side tubes 77 and filter plates 78 are arranged in a linear array with equal spacing, so that the chemical can enter the soil at different depths.

[0057] In this embodiment, when the drill rod 59 moves or rotates axially, the groove 74 on the arc-shaped sidewall of the drill rod 59 will drive the block 73 on the arc-shaped outer wall of the cylinder 72 to slide axially synchronously inside the groove 74, and at the same time drive the cylinder 72 to rotate inside the fixed block 71. When the drill rod 59 just slides downward outside the cylinder 72, the side groove 75 on the arc-shaped sidewall of the cylinder 72 is always connected to the through hole 510 and the cavity 511. Therefore, the chemical or clean water in the treatment component 5 can always be injected into the drill rod 59 through the bottom one-way valve 76 inside the end of the cylinder 72 away from the fixed block 71. However, at this time, the pipe wall of the cylinder 72 will block the side pipe 77 on the drill rod 59, so that the chemical or clean water cannot be sprayed out from the side pipe 77. When the drill rod 59 continues to penetrate deeper into the soil... During drilling, multiple sets of equally spaced linearly arrayed side tubes 77 on the vertically positioned drill rod 59 pass over the bottom of the cylinder 72 sequentially from bottom to top. The cylinder 72 then no longer obstructs these side tubes 77, allowing the chemical or water to spray out from the unobstructed side tubes 77. This allows for control of the chemical spraying position according to the drilling depth, avoiding waste of chemical or water in shallow soil that does not require treatment or outside the borehole, thus saving costs. At the same time, it allows the chemical to penetrate the soil at different depths evenly, significantly improving treatment efficiency. The sprayed high-pressure water can form a barrier at the opening of the side tubes 77 and the conical cover 520, preventing soil from entering in reverse. The filter plate 78 fixedly installed inside the side tubes 77 can further prevent impurities from entering the side tubes 77 and causing blockage.

[0058] In one embodiment of the present invention, a protective component 8 is provided on the outside of the drill rod 59. The protective component 8 includes a clamp 81. The clamp 81 is externally clamped at one end of the drill rod 59 away from the conical cover 520. One end of the L-shaped plate 82 is fixedly connected to the outside of the clamp 81. A frame 83 is fixedly installed on the other end of the L-shaped plate 82. A threaded post 84 is threaded inside the frame 83. A circular plate 85 is fixedly installed on the outside of the threaded post 84. In addition, a connecting pipe 86 is fixedly installed inside the L-shaped plate 82. A main airbag 87 and a secondary airbag 88 are fixedly installed at both ends of the connecting pipe 86, respectively. The main airbag 87 is located inside the frame 83, and the secondary airbag 88 is located inside the cylinder 72. The connecting pipe 86 passes through the side groove 75, thereby preventing external impurities from entering the inside of the cylinder 72 and playing a protective role.

[0059] In this embodiment, the L-shaped plate 82 is securely installed on the outside of the drill rod 59 away from the conical cover 520 by clamp 81. Rotating the threaded post 84 inside the frame 83 causes the circular plate 85 to move towards the main air bladder 87 and compress the main air bladder 87. Under pressure, the gas inside the main air bladder 87 is injected into the secondary air bladder 88 through the connecting pipe 86. After the secondary air bladder 88 expands, it will fit tightly against the inside of the cylinder 72, thereby forming a sealing barrier between the cylinder 72 and the drill rod 59. This effectively prevents external soil, sand and gravel and other impurities from entering the inside of the cylinder 72, providing good protection, extending the service life of the equipment, and making the overall equipment more practical.
