Description

Technical Field

[0001] This invention belongs to the field of sampling technology, specifically a sampling device for geological surveying in engineering construction. Background Technology

[0002] In the field of engineering construction, geological surveying is a crucial step in the early stages of a project, and its results directly affect the rationality and safety of subsequent engineering planning, design, and construction. Sampling, as a key step in geological surveying, can directly obtain crucial information such as the physical and chemical properties of underground soil layers, and is now mostly carried out using high-tech sampling equipment.

[0003] In actual operation, existing geological survey sampling devices first rely on a motor to drive the drill pipe to drill into the target soil. After drilling is completed, the drill pipe needs to be moved up and removed. This is only the initial operation. After removing the drill pipe, the soil column inside the pipe needs to be slid out by tapping. The whole process involves many steps, is cumbersome, and reduces sampling efficiency. Furthermore, when drilling downwards to extract soil, the soil column moves relatively upwards from the inside of the drill pipe. This causes a large amount of upward-oriented soil to adhere to the inner wall of the drill pipe. When a tapping operation is performed, the soil column slides downwards under pressure. At this time, the friction between the soil column and the inner wall of the drill pipe increases significantly. This increased friction acts like an "adhesive," causing more soil to adhere tightly to the inner wall of the drill pipe, making it difficult to clean. Moreover, during the sliding process, the originally compact soil column structure is destroyed and becomes loose. The loose soil column cannot accurately reflect the true state of the original soil layer, resulting in deviations in the composition and structure of the obtained sample from the actual soil layer. This seriously affects the sampling quality and may mislead subsequent geological analysis and engineering planning, leading to potential safety hazards and economic losses.

[0004] Therefore, the present invention provides a sampling device for geological surveying in engineering construction. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The sampling device for geological survey of engineering construction according to the present invention includes a body, two support frames are fixedly connected to the upper surface of the body, a drill pipe is arranged between the two support frames, a through fixed opening is opened inside the drill pipe, an adjustment component is arranged between the two support frames, the adjustment component includes a first guide rail opened on one side of the support frame, a first guide block is slidably connected in each first guide rail, a rotating plate is rotatably connected between the two first guide blocks, a support plate is fixedly connected to the upper surface of the rotating plate, and a built-in motor is arranged inside one of the first guide blocks for driving the rotating plate to rotate; The upper surface of the machine body is also provided with a processing component, which includes a third guide rail fixed to the upper surface of the machine body. A fixed column is slidably connected to the upper surface of the third guide rail, and the fixed column is used to push out the soil column inside the drill pipe.

[0007] Preferably, the processing component further includes a second guide rail fixed to the upper surface of the machine body. The upper surface of the second guide rail is provided with a sliding groove, and a sliding rod is slidably connected in the sliding groove. An arc-shaped plate is fixed to the top of the sliding rod.

[0008] Preferably, after the sampling device completes sampling, a soil column is stored in the drill pipe. Then, the adjustment component is activated. The activation of the adjustment component will first activate the built-in motor inside one of the first guide blocks. The activation of the built-in motor will drive the support plate to rotate 90 degrees counterclockwise, so that the drill pipe is aligned with the fixed column of the processing component. Then, the fixed shaft slidably connected to the upper surface of the third guide rail will be activated. The fixed column will push the soil column in the drill pipe along its drilling direction and push it onto the arc plate slidably set above the second guide rail, thereby completing the acquisition of the soil column.

[0009] Preferably, a fixed motor is fixedly connected to the upper surface of the support plate, a worm is fixedly connected to the output end of the fixed motor, a worm wheel is fixedly connected to the circumferential surface of the drill pipe, the worm and the worm wheel mesh with each other, and a protective cover is provided on the surface of the support plate to protect the worm wheel and worm.

[0010] Preferably, the bottom end of the drill pipe is provided with a cutting component, which is used to connect the bottom end of the soil column inside the drill pipe to the ground. The cutting component includes several fixing blocks fixed to the bottom end of the drill pipe. Each fixing block has a fixing groove on its inner wall. A compression spring is fixed to the inner wall of the fixing groove. A positioning block is fixed to one end of the compression spring. The positioning block has a conical cross-section.

[0011] Preferably, the processing component further includes a positioning rod slidably connected on a third guide rail, a positioning box fixedly connected to the top of the positioning rod, an auxiliary disk fixedly connected to one side of the positioning box, a reciprocating screw fixedly connected to one side of the auxiliary disk, and a fixing post fixedly connected to one end of the reciprocating screw.

[0012] Preferably, an auxiliary block is slidably connected to the circumferential surface of the reciprocating screw, and a semi-ring is fixedly connected to both sides of the auxiliary block. The surface of the semi-ring is a brush. Two limiting posts are fixedly connected to one side of the auxiliary plate. The limiting posts pass through the auxiliary block and are fixedly connected to the fixed post. The limiting posts are slidable by the auxiliary semi-ring.

[0013] Preferably, a telescopic tube is fixedly connected to the upper surface of the auxiliary block, one end of which is fixedly connected to the positioning box. The positioning box contains water, which is pressurized by a pressure pump inside the positioning box and flows into the semi-ring along the telescopic tube. Several nozzles are opened on the circumferential surface of the semi-ring, and water is sprayed out from the nozzles during the process of cleaning the inner wall of the pipe by the semi-ring.

[0014] Preferably, a limiting plate is fixed to one side of the semi-ring. The lower surface of the limiting plate has several nozzles arranged in an inclined array. The nozzles are oriented in the opposite direction to the movement of the fixed column. The nozzles can spray high-pressure water to flush out the cleaned cement mixture. The inclined array arrangement allows the cement mixture to flow out along one side of the drill pipe. The auxiliary plate and the positioning box have a through connecting groove to assist the movement of the limiting plate.

[0015] Preferably, a first cavity is provided on one side of the fixed column, and a spring is fixedly connected in the first cavity. A pressure sensor is fixedly connected to one end of the spring. When the fixed column comes into contact with the soil column in the drill pipe, the fixed column is squeezed by the soil column, which squeezes the pressure sensor. After the pressure sensor senses the pressure, it starts the pressure pump in the positioning and begins to inject water into the semi-ring and the limiting plate to carry out the inner wall treatment of the drill pipe.

[0016] The beneficial effects of this invention are as follows: 1. The sampling device for geological surveying in engineering construction described in this invention uses a fixed motor to drive a worm gear to efficiently drill a soil column. After sampling, the adjustment component takes effect. First, the built-in motor rotates the support plate to align the drill pipe with the fixed column. Then, the fixed column pushes the soil column onto the arc plate along the drilling direction, reducing friction during the pushing process and resulting in higher quality soil columns. The entire process is highly automated, with smooth and continuous operation, enabling rapid and accurate acquisition of soil columns, effectively improving sampling efficiency and accuracy.

[0017] 2. The sampling device for geological surveying in engineering construction described in this invention uses a pressure sensor to accurately sense the position of the soil column and automatically initiates the cleaning program, improving the automation and convenience of operation. The reciprocating semi-ring, in conjunction with the brush and water spray device, can comprehensively and thoroughly clean the inner wall of the drill pipe, effectively removing residual soil and impurities, ensuring the cleanliness of the drill pipe interior, providing good conditions for subsequent sampling, and avoiding the impact of dirt on the inner wall of the drill pipe on the accuracy and sample quality of the next sampling. At the same time, the setting of the limiting column enhances the stability of the semi-ring movement, ensuring that the cleaning process is efficient and reliable.

[0018] 3. The sampling device for geological surveying in engineering construction described in this invention, during the cleaning of the inner wall of the drill pipe by the processing components, after the brush on the semi-ring removes cement mixture and other dirt, the inclined array of nozzles on the lower surface of the limiting plate comes into play. Since the nozzles are oriented in the opposite direction to the movement of the fixed column, when the pressure pump is started, water enters the limiting plate and is sprayed out from the nozzles, forming a high-pressure water flow that forcefully flushes out the cleaned cement mixture. Moreover, the inclined array setting creates a certain angle for the water flow, allowing the cement mixture to flow smoothly out along one side of the drill pipe. At the same time, the through-connection groove between the auxiliary plate and the positioning box provides space and guidance for the movement of the limiting plate, ensuring that the limiting plate can move stably with the semi-ring and continuously flush different positions inside the drill pipe, further improving the cleaning effect of the inner wall of the drill pipe. The high-pressure water flow can thoroughly flush away the residual cement mixture, preventing it from clogging the drill pipe. The inclined array of nozzles makes the cleaning more efficient and orderly, ensuring the cleanliness of the inside of the drill pipe, which is beneficial for subsequent sampling work, and improving the reliability and practicality of the entire sampling device.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1 to 8 As shown in the embodiment of the present invention, a sampling device for geological surveying in engineering construction includes a body 1. Two support frames 2 are fixedly connected to the upper surface of the body 1. A drill pipe 25 is arranged between the two support frames 2. A through fixed opening 29 is opened inside the drill pipe 25. An adjustment component is arranged between the two support frames 2. The adjustment component includes a first guide rail 21 opened on one side of the support frame 2. A first guide block 22 is slidably connected in each first guide rail 21. A rotating plate 23 is rotatably connected between the two first guide blocks 22. A support plate 24 is fixedly connected to the upper surface of the rotating plate 23. A built-in motor is arranged inside one of the first guide blocks 22 to drive the rotating plate 23 to rotate. A processing component is also arranged on the upper surface of the body 1. The processing component includes a third guide rail 4 fixed to the upper surface of the body 1, with a fixed column 45 slidably connected to the upper surface of the third guide rail 4. The fixed column 45 is used to push out the soil column inside the drill pipe 25. The processing component also includes a second guide rail 3 fixed to the upper surface of the body 1. A groove 31 is opened on the upper surface of the second guide rail 3. A slide rod 32 is slidably connected in the groove 31. An arc plate 33 is fixed to the top of the slide rod 32. A fixed motor 26 is fixed to the upper surface of the support plate 24. A worm gear 27 is fixed to the output end of the fixed motor 26. A worm wheel 28 is fixed to the circumferential surface of the drill pipe 25. The worm gear 27 meshes with the worm wheel 28. A protective cover 214 is provided on the surface of the support plate 24. The protective cover 214 is used to protect the worm wheel 28 and the worm gear 27.

[0023] Specifically, in actual operation, existing geological survey sampling devices first rely on a motor to drive the drill pipe 25 to drill into the target soil. After drilling is completed, the drill pipe 25 needs to be moved up and removed. This is only the initial operation. After removing the drill pipe 25, the soil column inside the pipe needs to be slid out by tapping. The whole process involves many steps, is cumbersome, and reduces sampling efficiency. Furthermore, when drilling downwards in the drill pipe 25, the soil column moves upwards from the inside of the drill pipe 25. This causes a large amount of upward-oriented soil to adhere to the inner wall of the drill pipe 25. When a tapping operation is performed, the soil column slides downwards under the force. At this time, the friction between the soil column and the inner wall of the drill pipe 25 increases significantly. This increased friction acts like an "adhesive," causing more soil to adhere tightly to the inner wall of the drill pipe 25, making it difficult to clean. Moreover, during the sliding process, the originally compact soil column structure is destroyed and becomes loose. The loose soil column cannot accurately reflect the true state of the original soil layer, resulting in deviations between the obtained sample and the actual soil layer in terms of composition and structure. This seriously affects the sampling quality and may mislead subsequent geological analysis and engineering planning, leading to potential safety hazards and economic losses. Therefore, the present invention sets up the above structure according to the above problems. First, the fixed motor 26 on the upper surface of the support plate 24 is started. The fixed motor 26 drives the worm 27 to rotate. The rotation of the worm 27 drives the worm wheel 28 to move actively, and then drives the drill pipe 25 to perform drilling work. When the sampling device completes sampling, the drill pipe 25 stores a soil column. Then, the adjustment component is started. The start of the adjustment component will first start the built-in motor inside one of the first guide blocks 22. The start of the built-in motor drives the support plate 24 to rotate counterclockwise by 90 degrees, so that the drill pipe 25 is aligned with the fixed column 45 of the processing component. Then, the fixed shaft slidably connected to the upper surface of the third guide rail 4 is started. The soil column in the drill pipe 25 is pushed out along its drilling direction through the fixed column 45 and pushed onto the arc plate 33 slidably set above the second guide rail 3, thereby completing the soil column acquisition work. The fixed motor 26 drives the worm gear 27 and worm wheel 28 to drive the drill pipe 25 to efficiently drill a soil column. After sampling, the adjustment component plays a role. First, the built-in motor rotates the support plate 24 to align the drill pipe 25 with the fixed column 45. Then, the fixed column 45 pushes the soil column onto the arc plate 33 along the drilling direction, reducing friction during the pushing process and resulting in higher quality soil column extraction. The whole process is highly automated, with smooth and continuous operation, and can quickly and accurately obtain soil columns, effectively improving sampling efficiency and accuracy.

[0024] like Figure 5 As shown, in this embodiment, the bottom end of the drill pipe 25 is provided with a cutting component. The cutting component is used to connect the bottom end of the soil column inside the drill pipe 25 with the soil. The cutting component includes several fixing blocks 210 fixed to the bottom end of the drill pipe 25. Each fixing block 210 has a fixing groove 211 on its inner wall. A compression spring 212 is fixed to the inner wall of the fixing groove 211. One end of the compression spring 212 is fixed to a positioning block 213. The cross section of the positioning block 213 is conical.

[0025] Specifically, when the drill pipe 25 completes sampling, the electro-permanent magnet block installed on the inner wall of the fixing groove 211 is energized, making it magnetic. This repulses the compression spring 212, causing the positioning block 213 to pop outwards. At this point, the conical positioning block 213 inserts into the contact point between the bottom of the soil column and the surrounding soil. Utilizing the squeezing and cutting force generated by its conical structure, the connection between the bottom of the soil column and the soil is severed, ensuring the soil column remains intact within the drill pipe 25 for subsequent removal and processing. This allows for a quick and effective severing of the connection between the soil column and the soil during sampling, preventing breakage or fragmentation during removal, ensuring the integrity and accuracy of the sample, providing a reliable sample for subsequent soil analysis, and improving the quality and efficiency of the sampling work.

[0026] Example 2: Figures 1 to 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the processing component further includes a positioning rod 41 slidably connected to the third guide rail 4, a positioning box 42 fixedly connected to the top of the positioning rod 41, an auxiliary disk 43 fixedly connected to one side of the positioning box 42, a reciprocating screw 44 fixedly connected to one side of the auxiliary disk 43, and a fixing post 45 fixedly connected to one end of the reciprocating screw 44; an auxiliary block 46 is slidably connected to the circumferential surface of the reciprocating screw 44, and half-rings 47 are fixedly connected to both sides of the auxiliary block 46. The surfaces of the half-rings 47 are all brushes. Two limiting posts 49 are fixedly connected to one side of the auxiliary plate. The limiting posts 49 penetrate the auxiliary block 46 and are fixedly connected to the fixing post 45. The limiting posts 49 are fixed by the sliding of the auxiliary half-rings 47; a telescopic tube 412 is fixedly connected to the upper surface of the auxiliary block 46, and one end of the telescopic tube 412 is connected to the positioning box 42. The positioning box 42 is fixedly connected, and water is stored inside the positioning box 42. The water is pressurized by the pressure pump inside the positioning box 42 and flows into the semi-ring 47 along the telescopic pipe 412. Several nozzles 48 are opened on the circumferential surface of the semi-ring 47, and water is sprayed out from the nozzles 48. During the process of cleaning the inner wall of the pipe by the semi-ring 47, a first cavity 414 is opened on one side of the fixed column 45. A spring 415 is fixedly connected in the first cavity 414, and a pressure sensor 416 is fixedly connected to one end of the spring 415. When the fixed column 45 comes into contact with the soil column in the drill pipe 25, the fixed column 45 is squeezed by the soil column, which squeezes the pressure sensor 416. After the pressure sensor 416 senses the pressure, it starts the pressure pump in the positioning box and begins to inject water into the semi-ring 47 and the limiting plate 410 to carry out the inner wall treatment of the drill pipe 25.

[0027] Specifically, when the processing component is working, when the fixed column 45 contacts the soil column inside the drill pipe 25, the soil column squeezes the fixed column 45, causing the spring 415 inside the first cavity 414 to compress, thereby triggering the pressure sensor 416. After the pressure sensor 416 senses the pressure, it starts the pressure pump inside the positioning box 42. The water in the positioning box 42 is pressurized by the pressure pump and flows along the telescopic pipe 412 into the semi-rings 47 on both sides of the auxiliary block 46. Since the surface of the semi-rings 47 is a brush and several nozzles 48 are opened on the circumference, water is sprayed out from the nozzles 48. The reciprocating screw 44 drives the auxiliary block 46 to slide, causing the auxiliary block 46 to reciprocate on the reciprocating screw 44, which in turn drives the semi-ring 47 to move back and forth on the inner wall of the drill pipe 25. During the movement, the brush on the semi-ring 47 scrubs the inner wall of the drill pipe 25, and the sprayed water washes away the dirt brushed off, thus achieving cleaning. The limiting post 49 passes through the auxiliary block 46 and is fixedly connected to the fixed post 45, which can assist the semi-ring 47 to slide stably. In addition, the telescopic tube 412 fixed to the upper surface of the auxiliary block 46 can extend and retract with the movement of the auxiliary block 46 to ensure unobstructed water flow. The pressure sensor 416 accurately senses the position of the soil column and automatically initiates the cleaning program, improving the automation and convenience of the operation. The reciprocating semi-ring 47, in conjunction with the brush and water spray device, can thoroughly clean the inner wall of the drill pipe 25, effectively removing residual soil and impurities, ensuring the cleanliness of the inside of the drill pipe 25, providing good conditions for subsequent sampling, and avoiding the impact of dirt on the inner wall of the drill pipe 25 on the accuracy and sample quality of the next sampling. At the same time, the setting of the limiting column 49 enhances the stability of the movement of the semi-ring 47, ensuring that the cleaning process is efficient and reliable.

[0028] like Figure 7 As shown, in this embodiment, a limiting plate 410 is also fixed to one side of the semi-ring 47. The lower surface of the limiting plate 410 has a plurality of nozzles 411 arranged in an inclined array. The nozzles 411 are oriented in the opposite direction to the moving direction of the fixed column 45. The nozzles 411 can spray high-pressure water to flush out the cleaned cement mixture. The inclined array arrangement allows the cement mixture to flow out along one side of the drill pipe 25. The auxiliary plate 43 and the positioning box 42 are provided with a through connecting groove 413 to assist the movement of the limiting plate 410.

[0029] Specifically, during the cleaning process of the inner wall of the drill pipe 25 by the processing components, after the brush on the semi-ring 47 removes cement mixture and other dirt, the nozzles 411 of the inclined array on the lower surface of the limiting plate 410 come into play. Since the nozzles 411 are oriented in the opposite direction to the movement of the fixed column 45, when the pressure pump is started, water enters the limiting plate 410 and is sprayed out from the nozzles 411, forming a high-pressure water flow that forcefully flushes out the cleaned cement mixture. Moreover, the inclined array arrangement creates a certain angle for the water flow, allowing the cement mixture to flow smoothly out along one side of the drill pipe 25. The through-connection groove 413 between the auxiliary plate 43 and the positioning box 42 provides space and guidance for the movement of the limiting plate 410, ensuring that the limiting plate 410 can move stably with the semi-ring 47, continuously flushing different positions inside the drill pipe 25, further improving the cleaning effect of the inner wall of the drill pipe 25. The high-pressure water flow can thoroughly wash away the residual cement mixture, preventing it from clogging the drill pipe 25. The inclined array nozzle 411 makes the cleaning more efficient and orderly, ensuring the cleanliness of the inside of the drill pipe 25, which is conducive to subsequent sampling work and improves the reliability and practicality of the entire sampling device.

[0030] The working principle is as follows: First, the fixed motor 26 on the upper surface of the support plate 24 is activated. The fixed motor 26 drives the worm gear 27 to rotate, which in turn drives the worm wheel 28 to actively move, thereby driving the drill pipe 25 to perform drilling. When the drill pipe 25 completes sampling, the electro-permanent magnet block set on the inner wall of the fixed groove 211 is energized, making it magnetic. Then, it repels the compression spring 212. The compression spring 212 is subjected to repulsive force, pushing the positioning block 213 outward. At this time, the conical positioning block 213 will insert into the contact point between the bottom end of the soil column and the surrounding soil. Utilizing the squeezing force and cutting action generated by its conical structure, the connection between the bottom end of the soil column and the soil is cut off, so that the soil column is completely preserved in the drill pipe 25, which is convenient for subsequent removal and processing. In this way, the connection between the soil column and the soil can be quickly and effectively cut off during the sampling process, avoiding the soil column from breaking or fragmenting when it is removed, ensuring the integrity and accuracy of the sampling, providing a reliable sample for subsequent soil analysis, and improving the quality and efficiency of the sampling work. Then, the soil column is stored in the drill pipe 25. The adjustment component is then activated. The activation of the adjustment component will first activate the built-in motor inside one of the first guide blocks 22. The activation of the built-in motor will drive the support plate 24 to rotate 90 degrees counterclockwise, so that the drill pipe 25 is aligned with the fixed column 45 of the processing component. Then, the fixed shaft slidably connected to the upper surface of the third guide rail 4 will be activated. The soil column in the drill pipe 25 will be pushed out along the drilling direction through the fixed column 45 and pushed onto the arc plate 33 slidably set above the second guide rail 3, thereby completing the soil column acquisition work. The fixed motor 26 drives the worm gear 27 and worm wheel 28 to drive the drill pipe 25 to efficiently drill a soil column. After sampling, the adjustment component plays a role. First, the built-in motor rotates the support plate 24 to align the drill pipe 25 with the fixed column 45. Then, the fixed column 45 pushes the soil column onto the arc plate 33 along the drilling direction, reducing the friction during the pushing process and making the quality of the soil column higher. The whole process is highly automated, the operation is smooth and continuous, and the soil column can be obtained quickly and accurately, effectively improving the sampling efficiency and accuracy. When the other processing component is working, when the fixed column 45 contacts the soil column inside the drill pipe 25, the soil column squeezes the fixed column 45, causing the spring 415 inside the first cavity 414 to compress, thereby triggering the pressure sensor 416. After the pressure sensor 416 senses the pressure, it starts the pressure pump inside the positioning box 42. The water in the positioning box 42 is pressurized by the pressure pump and flows into the semi-rings 47 on both sides of the auxiliary block 46 along the telescopic pipe 412. Since the surface of the semi-rings 47 is a brush and several nozzles 48 are opened on the circumference, water is sprayed out from the nozzles 48, and at the same time... The reciprocating screw 44 drives the auxiliary block 46 to slide, causing the auxiliary block 46 to reciprocate on the reciprocating screw 44, which in turn drives the semi-ring 47 to move back and forth on the inner wall of the drill pipe 25. During the movement, the brush on the semi-ring 47 scrubs the inner wall of the drill pipe 25, and the sprayed water washes away the dirt brushed off, thus achieving cleaning. The limiting post 49 passes through the auxiliary block 46 and is fixedly connected to the fixed post 45, which can assist the semi-ring 47 to slide stably. In addition, the telescopic tube 412 fixed to the upper surface of the auxiliary block 46 can extend and retract with the movement of the auxiliary block 46 to ensure unobstructed water flow. The pressure sensor 416 accurately senses the position of the soil column and automatically starts the cleaning program, improving the automation and convenience of the operation. The reciprocating semi-ring 47, together with the brush and water spray device, can thoroughly clean the inner wall of the drill pipe 25, effectively removing residual soil and impurities, ensuring the cleanliness of the inside of the drill pipe 25, providing good conditions for subsequent sampling, and avoiding the impact of dirt on the inner wall of the drill pipe 25 on the accuracy and sample quality of the next sampling. At the same time, the setting of the limiting column 49 enhances the stability of the movement of the semi-ring 47, ensuring that the cleaning process is efficient and reliable. Finally, during the cleaning process of the inner wall of the drill pipe 25 by the processing components, after the brush on the semi-ring 47 removes cement mixture and other dirt, the nozzles 411 of the inclined array on the lower surface of the limiting plate 410 come into play. Since the nozzles 411 are oriented in the opposite direction to the movement of the fixed column 45, when the pressure pump is started, water enters the limiting plate 410 and is sprayed out from the nozzles 411, forming a high-pressure water flow that forcefully flushes out the cleaned cement mixture. Moreover, the inclined array setting creates a certain angle for the water flow, allowing the cement mixture to flow smoothly out along one side of the drill pipe 25. At the same time, the auxiliary... The through-connection groove 413 between the auxiliary plate 43 and the positioning box 42 provides space and guidance for the movement of the limiting plate 410, ensuring that the limiting plate 410 can move stably with the semi-ring 47, continuously flushing different positions inside the drill pipe 25, further improving the cleaning effect of the inner wall of the drill pipe 25. The high-pressure water flow can thoroughly wash away the residual cement mixture, preventing it from clogging the drill pipe 25. The inclined array nozzle 411 makes the cleaning more efficient and orderly, ensuring the cleanliness of the inside of the drill pipe 25, which is conducive to subsequent sampling work and improves the reliability and practicality of the entire sampling device.
