Description

Technical Field

[0001] The invention belongs to the technical field of soil environmental investigation, in particular to a soil sampling device used for soil environmental investigation. Background Art

[0002] In soil environmental surveys and research, accurate soil collection is the basis for obtaining key information such as soil quality, pollution status, and ecological health. Traditional soil sampling methods often rely on manual excavation or the use of simple sampling tools. These methods are not only labor-intensive and inefficient, but also difficult to ensure the depth and uniformity of sampling, especially in complex terrain or inaccessible areas. Sampling is more difficult. In addition, manual sampling can easily damage the soil structure, affecting the accuracy of subsequent analysis results.

[0003] With the development of science and technology, automation and intelligent technology have been increasingly used in the field of soil environmental investigation. However, most of the existing soil sampling devices have problems such as complex structure, cumbersome operation, and poor adaptability, which makes it difficult to meet the diverse soil sampling needs. Especially under different soil types, humidity and depth conditions, how to achieve efficient and accurate soil sample collection has become a technical problem that needs to be solved urgently in the current field of soil environmental investigation. Therefore, it is particularly important to develop a soil environment investigation soil sampling device with a simple structure, convenient operation and strong adaptability. The device should be able to flexibly adjust the sampling depth and angle according to different soil conditions and sampling requirements to ensure the accuracy and representativeness of the sampling. At the same time, the device should also have a stable support structure and clamping mechanism to ensure the stability and safety of the equipment during the sampling process. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a soil sample collection device for soil environment investigation.

[0005] The technical solution adopted to solve the above technical problems is: a soil environment survey soil sample collection device, comprising a bracket, a top plate is provided on the top inner wall of the bracket, and a lifting motor is fixedly installed on one side of the inner wall of the top plate, and the output shaft of the lifting motor is connected with a lifting mechanism for adjusting the lifting height of the sampler;

[0006] A support plate is provided at the front end of the bracket, and a rotating mechanism is provided on one side of the outer wall of the support plate;

[0007] The central part of the support plate is provided with a notch, and the rotating shaft of the rotating assembly is connected with a sampling mechanism for collecting and recovering soil samples;

[0008] A bottom plate is arranged at the bottom of the bracket, and clamping mechanisms are arranged on both sides of the front end of the bottom plate, which are used to stabilize the sampling mechanism during the rotation and lifting process.

[0009] Through the above technical scheme, the bracket, as the main supporting structure of the entire device, can be made of high-strength, corrosion-resistant materials to ensure stability and durability in complex environments. A top plate is provided on the inner wall at the top of the bracket, and the top plate is used to fix the lifting motor and provide a power source for the lifting mechanism. A support plate is provided at the front end of the bracket for installing the rotating mechanism and the sampling mechanism; a bottom plate is provided at the bottom for installing the clamping mechanism and serving as the supporting basis of the entire device. The lifting mechanism is connected to the output shaft of the lifting motor and is converted into the vertical lifting movement of the sampling mechanism through the rotational motion of the motor. The lifting column is installed on the left side of the center of the bottom plate, and the piston rod at its top is fixedly connected to the rear of the support plate through a connecting plate to assist the lifting movement of the support plate and improve the stability and smoothness during the lifting process. The rotating mechanism is installed at the center of the support plate and is used to drive the sampling mechanism to perform horizontal rotation sampling. The rotating bracket is fixed on the support plate to provide an installation basis for the rotating motor and the rotating shaft. The rotating motor is connected to the rotating shaft through its output shaft The rotating shaft passes through the supporting plate and is connected to the sampling mechanism, thereby transmitting the rotational motion of the motor to the sampling mechanism to realize the horizontal rotation of the sampling mechanism. The sampling mechanism is the core component of the device and is used for actually collecting soil samples. The rotating rod is connected to the rotating shaft and rotates with the rotating shaft. A spiral rod is arranged at the bottom of the rotating rod, and the spiral rod is connected to the drilling column. The soil is drilled into the drilling column through rotation and thrust movement. A soil sampling column is arranged inside the drilling column for collecting the drilled soil samples. A drill bit is fixedly installed at the bottom of the drilling column. The drill bit can be made of cemented carbide material and has good wear resistance and cutting performance, ensuring that the soil can be drilled smoothly and samples can be collected. The clamping mechanism is arranged on both sides of the front end of the bottom plate, which is used to stabilize the sampling mechanism during the sampling process to prevent it from affecting the sampling accuracy due to vibration or offset. The clamping plate is fixed on the bottom plate to provide an installation foundation for the cylinder. The cylinder is connected to the push plate through its front end piston rod. A sponge sleeve is arranged at the front end center of the push plate for contacting with the sampling mechanism and applying a stable clamping force.

[0010] Furthermore, the lifting mechanism comprises a lifting chain sleeved on the rotating wheel of the lifting motor, and a sliding column is sleeved on one end of the lifting chain away from the rotating wheel.

[0011] Through the above technical scheme, the lifting mechanism realizes precise control and stable lifting of the sampling mechanism in the vertical direction. The lifting chain serves as a transmission element, and its high strength and wear resistance ensure reliability for long-term use. When the lifting motor is started, its rotating wheel drives the lifting chain to rotate, thereby driving the sliding column to move in the vertical direction. The connection method between the sliding column and the lifting chain ensures effective power transmission. At the same time, the linear motion of the sliding column is converted into the lifting motion of the sampling mechanism. In order to further improve the stability and accuracy during the lifting process, the sliding column is designed to be embedded in the slide grooves on both sides of the bracket. The slide grooves not only provide a guide for the sliding column, but also limit its movement in the horizontal direction, ensuring that the lifting motion is carried out along a predetermined trajectory.

[0012] Furthermore, the inner walls on both sides of the bracket are provided with sliding grooves, the sliding column is embedded in the sliding groove, one side of the outer surface of the sliding column is fixedly installed on the support plate, and lifting wheels are installed on both sides of the outer wall at the rear end of the support plate, and the lifting wheels are slidably connected in the sliding groove.

[0013] Through the above technical scheme, on the basis of the lifting mechanism, the design of the slide groove and lifting wheel is added, which further improves the stability and smoothness of the lifting process. The design of the slide groove not only provides precise guidance for the lifting wheel, but also reduces the friction between the lifting wheel and the lifting wheel through the smooth treatment of its inner wall, making the lifting movement smoother. These lifting wheels are closely matched with the slide groove and roll with the lifting and lowering of the support plate, which effectively disperses the weight of the support plate and its upper components and reduces the load-bearing burden of the sliding column. The combined design of the lifting wheel and the slide groove also enhances the adaptability of the entire lifting system, ensuring the accuracy and reliability of the sampling mechanism during the lifting process.

[0014] Furthermore, the lifting mechanism also includes a lifting column arranged on the left side of the center of the bottom plate, and a connecting plate is fixedly installed on the top of the piston rod of the lifting column, and the connecting plate is fixedly installed on the outer wall of the rear end of the support plate.

[0015] Through the above technical scheme, the lifting column complements the previous lifting chain and sliding column to ensure the stability and balance of the sampling mechanism during the lifting process. The lifting column is an auxiliary lifting device, and its design fully considers the overall structure and working requirements of the equipment. The piston rod installed on the top of the lifting column is driven by hydraulic or pneumatic pressure to achieve precise telescopic movement. The piston rod is fixedly connected to the connecting plate, and the connecting plate is firmly installed on the rear of the support plate. When the piston rod of the lifting column is extended or shortened, it will drive the support plate and the rotating mechanism and the sampling mechanism installed thereon to rise and fall together through the connecting plate. It increases the support points and force area of ​​the lifting mechanism, making the lifting process more stable and reliable. The lifting column is located to the left of the center of the bottom plate. It can also provide certain lateral support for the sampling mechanism during the lifting process to prevent it from shaking or tilting due to the shift of the center of gravity.

[0016] Furthermore, the rotating mechanism includes a rotating bracket arranged at the center of the supporting plate, and two fixed shafts are arranged on one side of the outer surface of the rotating bracket.

[0017] Through the above technical solution, the two fixed shafts provide a stable support foundation for the rotating mechanism, ensuring the smooth progress of the rotational motion. The fixed shaft is tightly combined with the rotating bracket through precise processing and installation to form a stable rotation center. When the rotating mechanism is working, the rotating motor will drive a transmission device, which is connected to the rotating shaft inside the rotating bracket. The rotating shaft is connected to the fixed shaft through bearings and other components, realizing the transmission of the rotational motion. When the rotating motor starts, the rotating shaft will rotate around the fixed shaft, thereby driving the entire sampling mechanism to rotate in the horizontal direction. The existence of the fixed shaft effectively prevents deviation and shaking during the rotation process, ensuring the accuracy and reliability of the rotational motion.

[0018] Furthermore, the rotating mechanism also includes a rotating motor arranged at the center of the outer wall of the rear end of the support plate, and the output shaft of the rotating motor passes through the support plate and is rotatably connected to the rotating shaft.

[0019] Through the above technical solution, the rotating motor is used as a power source, and its output shaft is directly connected to the rotating shaft, which reduces the energy loss and mechanical wear of the intermediate transmission link and improves the accuracy and stability of the rotational motion.

[0020] When the rotary motor is started, its output shaft will drive the rotary shaft to rotate together, and the rotary motion of the rotary shaft will be directly transmitted to the sampling mechanism, driving it to rotate in the horizontal direction.

[0021] Furthermore, the sampling mechanism includes a rotating rod arranged at the center of the rotating shaft, and a thread is arranged at the bottom of the rotating rod.

[0022] Through the above technical solution, the design of the threaded connection simplifies the installation and disassembly process of the sampling mechanism, so that the operator can easily complete the replacement and maintenance of the sampling mechanism. At the same time, since the sampling mechanism is an independent module, it can be troubleshooted and repaired separately, reducing the downtime and maintenance costs of the entire equipment. The rotating rod serves as a connecting component between the sampling mechanism and the rotating shaft, and the thread set at the bottom ensures a tight connection and precise alignment between the sampling mechanism and the rotating shaft.

[0023] Furthermore, the rotating rod is threadedly connected to a soil drilling column, a soil extraction column is arranged inside the soil drilling column, and a drill bit is fixedly installed at the bottom of the soil drilling column.

[0024] Through the above technical solution, when the rotating motor drives the rotating rod to rotate, the spiral rod and the drill bit will rotate synchronously and penetrate into the soil. The sharp edge of the drill bit can easily penetrate the soil, paving the way for subsequent sampling work. A slot is opened at the center of the drill bit, and the soil sampling column is located inside the drill column. As the drill column goes deeper and the spiral rod rotates, the soil will be collected into the soil sampling column through the slot at the center of the drill bit.

[0025] Furthermore, the clamping mechanism includes two clamping plates arranged on both sides of the outer wall of the front end of the bottom plate, and two cylinders are embedded in the two clamping plates.

[0026] Through the above technical solution, two clamping plates are respectively arranged on both sides of the front end of the base plate to form a stable clamping frame. This double-sided clamping design can more effectively disperse the clamping force, ensure stability during the clamping process, and reduce the possibility of shaking and deviation. When the sampling device needs to be fixed on the soil surface, the cylinder will receive a command to drive the clamping plate to move to both sides or the center, and its piston will push outward, driving the clamping plate to expand outward until it contacts the sampling mechanism.

[0027] Furthermore, the clamping mechanism includes a pushing plate fixedly mounted on the front ends of the plurality of cylinder piston rods, and a sponge sleeve is sleeved at the center of the front end of the pushing plate.

[0028] Through the above technical solution, the push plate is directly connected to the piston rod of the cylinder, and its movement accuracy is directly affected by the control accuracy of the cylinder. By adjusting the position of the push plate through the cylinder, precise control of the clamping force can be achieved. The sponge cover can enhance the softness and cushioning of the clamping. The softness and shock absorption of the sponge cover effectively reduce the noise and vibration generated during the clamping process, thereby improving the working environment. At the same time, the clamping mechanism can also guide the sampling mechanism.

[0029] The beneficial effects of the present invention are as follows: (1) The present invention enables the device to remain stable during the sampling process through the design of the lifting mechanism and the rotating mechanism, reducing the risk of shaking and tipping, thereby improving the safety of operation; (2) The present invention stabilizes the position of the sampling mechanism through the clamping mechanism, which helps to reduce the deviation during the sampling process, and can also absorb part of the mechanical vibration and impact during the clamping process, thereby reducing noise generation; (3) The present invention realizes the rapid replacement and positioning of the sampling mechanism through the threaded connection design of the rotating rod and the sampling mechanism, thereby improving efficiency.

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] like Figure 1 - Figure 2 As shown, a soil sample collection device for soil environment investigation of the present embodiment includes a bracket 1, a top plate 101 is provided on the top inner wall of the bracket 1, a support plate 102 is provided on the front end of the bracket 1, and a bottom plate 103 is provided on the bottom of the bracket 1. The bracket 1 serves as the main supporting structure of the entire device and can be made of high-strength, corrosion-resistant materials to ensure stability and durability in complex environments. A top plate 101 is provided on the top inner wall of the bracket 1, and the top plate 101 is used to fix and install a lifting motor 201 to provide a power source for the lifting mechanism 2. A support plate 102 is provided on the front end of the bracket 1 for installing a rotating mechanism 3 and a sampling mechanism 4; a bottom plate 103 is provided on the bottom of the bracket 1 for installing a clamping mechanism 5 and serving as a supporting base for the entire device.

[0040] like Figure 1 - Figure 4As shown, a lifting motor 201 is fixedly installed on one side of the inner wall of the top plate 101, and the output shaft of the lifting motor 201 is connected to a lifting mechanism 2 for adjusting the lifting height of the sampler. The lifting mechanism 2 includes a lifting chain 202 sleeved on the rotating wheel of the lifting motor 201, and a sliding column 203 is sleeved on the end of the lifting chain 202 away from the rotating wheel. Slide grooves 207 are opened on both sides of the inner wall of the bracket 1, and the sliding column 203 is embedded in the slide groove 207. One side of the outer surface of the sliding column 203 is fixedly installed on the support plate 102, and the outer wall of the rear end of the support plate 102 is installed with a lifting wheel 204, and the lifting wheel 204 is slidably connected in the slide groove 207. The lifting mechanism 2 also includes a lifting column 205 arranged on the left side of the center of the bottom plate 103, and the lifting column 205 A connecting plate 206 is fixedly installed on the top of the piston rod, and the connecting plate 206 is fixedly installed on the outer wall of the rear end of the support plate 102. The top plate 101 is used to fix the lifting motor 201 to provide a power source for the lifting mechanism 2. The lifting mechanism 2 realizes precise control and stable lifting of the sampling mechanism 4 in the vertical direction. The lifting chain 202 is used as a transmission element. Its high strength and wear resistance ensure reliability for long-term use. When the lifting motor 201 is started, its rotating wheel drives the lifting chain 202 to rotate, thereby driving the sliding column 203 to move in the vertical direction. The connection method between the sliding column 203 and the lifting chain 202 ensures the effective transmission of power. At the same time, the linear motion of the sliding column 203 is converted into the lifting motion of the sampling mechanism 4. In order to further improve In order to improve the stability and accuracy of the lifting process, the sliding column 203 is designed to be embedded in the sliding groove 207 on both sides of the bracket 1. The sliding groove 207 not only provides a guide for the sliding column 203, but also limits its movement in the horizontal direction, ensuring that the lifting movement is carried out along a predetermined trajectory. On the basis of the lifting mechanism 2, the design of the sliding groove 207 and the lifting wheel 204 is added to further improve the stability and smoothness of the lifting process. The design of the sliding groove 207 not only provides a precise guide for the lifting wheel 204, but also reduces the friction between the lifting wheel 204 and the lifting wheel 204 through the smooth treatment of its inner wall, making the lifting movement smoother. These lifting wheels 204 are closely matched with the sliding groove 207, rolling with the lifting and lowering of the support plate 102, effectively dividing The weight of the support plate 102 and its components is dispersed, and the load-bearing burden of the sliding column 203 is reduced. The combined design of the lifting wheel 204 and the slide chute 207 also enhances the adaptability of the entire lifting system, ensuring the accuracy and reliability of the sampling mechanism 4 during the lifting process. Safety protection measures are also considered in the design of the lifting mechanism 2. For example, a limit switch or sensor can be set to monitor the position of the sliding column 203. When the sliding column 203 reaches the preset upper and lower limit positions, the power supply of the lifting motor 201 is automatically cut off to prevent the equipment from being damaged or causing safety accidents due to excessive lifting. In addition, the design of the slide chute 207 also takes into account wear resistance and self-lubrication to reduce the friction and wear of the sliding column 203 during movement and extend its service life.The rotary motion of the lifting motor 201 is converted into the vertical lifting motion of the sampling mechanism 4. The lifting column 205 is installed at the center left of the bottom plate 103. The piston rod of the lifting column 205 is fixedly connected to the rear of the support plate 102 through the connecting plate 206 to assist the lifting motion of the support plate 102 and improve the stability and smoothness during the lifting process. The lifting column 205 complements the previous lifting chain 202 and the sliding column 203 to jointly ensure the stability and balance of the sampling mechanism 4 during the lifting process. As an auxiliary lifting device, the design of the lifting column 205 fully considers the overall structure and working requirements of the equipment. The piston installed on the top of the lifting column 205 The rod is driven by hydraulic or pneumatic pressure to achieve precise telescopic movement. The piston rod is fixedly connected to the connecting plate 206, and the connecting plate 206 is firmly installed at the rear of the support plate 102. When the piston rod of the lifting column 205 is extended or shortened, the supporting plate 102 and the rotating mechanism 3 and the sampling mechanism 4 installed thereon are driven to rise and fall together through the connecting plate 206. It increases the supporting points and force-bearing area of ​​the lifting mechanism 2, making the lifting process more stable and reliable. The lifting column 205 is located to the left of the center of the bottom plate 103. It can also provide certain lateral support for the sampling mechanism 4 during the lifting process to prevent it from shaking or tilting due to the offset of the center of gravity.

[0041] like Figure 5As shown, a rotating mechanism 3 is arranged on one side of the outer wall of the support plate 102, and the rotating mechanism 3 includes a rotating bracket 301 arranged at the center of the support plate 102, and two fixed shafts 304 are arranged on one side of the outer surface of the rotating bracket 301. The rotating mechanism 3 also includes a rotating motor 302 arranged at the rear center of the support plate 102, and the output shaft of the rotating motor 302 passes through the support plate 102 and is rotatably connected to the rotating shaft 303. The rotating mechanism 3 also includes a rotating motor 302 arranged at the center of the outer wall of the rear end of the support plate 102, and the output shaft of the rotating motor 302 passes through the support plate 1 02 is rotatably connected with a rotating shaft 303. The rotating mechanism 3 is installed at the center of the support plate 102 and is used to drive the sampling mechanism 4 to perform horizontal rotation sampling. The rotating bracket 301 is fixed on the support plate 102 to provide an installation basis for the rotating motor 302 and the rotating shaft 303. The rotating motor 302 is connected to the rotating shaft 303 through its output shaft. The rotating shaft 303 passes through the support plate 102 and is connected to the sampling mechanism 4, thereby transmitting the rotational motion of the rotating motor 302 to the sampling mechanism 4. The two fixed shafts 304 provide a stable support basis for the rotating mechanism. The fixed shaft 304 is precisely processed and installed to be tightly combined with the rotating bracket 301 to form a stable rotation center. When the rotating mechanism 3 is working, the rotating motor 302 drives a transmission device, which is connected to the rotating shaft 303 inside the rotating bracket 301. The rotating shaft 303 is connected to the fixed shaft 304 through bearings and other components to achieve the transmission of the rotating motion. When the rotating motor 302 is started, the rotating shaft 303 rotates around the fixed shaft 304, thereby driving the entire The sampling mechanism 4 rotates in the horizontal direction. The existence of the fixed shaft 304 effectively prevents deviation and shaking during the rotation process, ensuring the accuracy and reliability of the rotational movement. The rotating motor 302 serves as a power source, and its output shaft is directly connected to the rotating shaft 303, reducing the energy loss and mechanical wear of the intermediate transmission link, and improving the accuracy and stability of the rotational movement. When the rotating motor 302 is started, its output shaft will drive the rotating shaft 303 to rotate together, and the rotational movement of the rotating shaft 303 will be directly transmitted to the sampling mechanism 4, driving it to rotate in the horizontal direction.

[0042] like Figure 5 - Figure 6As shown, a notch is provided in the center of the support plate 102, and a sampling mechanism 4 is connected to the rotating shaft of the rotating assembly 3 for collecting and recovering soil samples. The sampling mechanism 4 includes a rotating rod 401 arranged at the center of the rotating shaft 303, and a thread is arranged at the bottom of the rotating rod 401. The rotating rod 401 is threadedly connected to a soil drilling column 402, and a soil sampling column 403 is arranged inside the soil drilling column 402. A drill bit 404 is fixedly installed at the bottom of the soil drilling column 402. The threaded connection design simplifies the installation and disassembly process of the sampling mechanism 4, so that the operator can easily complete the replacement and maintenance of the sampling mechanism 4. At the same time, since the sampling mechanism 4 is an independent module, it can be troubleshooted and repaired separately, reducing the whole The downtime and maintenance cost of the equipment, the rotating rod 401 serves as a connecting component between the sampling mechanism 4 and the rotating shaft 303, and the threaded portion at the bottom thereof ensures a tight connection and precise alignment between the sampling mechanism 4 and the rotating shaft 303. When the rotating motor 302 drives the rotating rod 401 to rotate, the drilling column 402 and the drill bit 404 will rotate synchronously and penetrate into the soil. The sharp edge of the drill bit 404 can easily penetrate the soil, paving the way for subsequent sampling work. A slot is provided at the center of the drill bit 404, and the soil sampling column 403 is located inside the drilling column 402. As the drilling column 402 penetrates deeper and the rotating rod 401 rotates, the soil will be collected into the soil sampling column 403 through the slot at the center of the drill bit 404.

[0043] like Figure 7As shown, both sides of the front end of the bottom plate 103 are provided with a clamping mechanism 5 for stabilizing the sampling mechanism 4 during the rotation and lifting process. The clamping mechanism 5 includes two clamping plates 501 arranged on both sides of the outer wall of the front end of the bottom plate 103. Two cylinders 502 are embedded in the two clamping plates 501. The clamping mechanism 5 also includes a pushing plate 503 fixedly installed on the front ends of the piston rods of the multiple cylinders 502, and a sponge cover 504 is sleeved at the center of the front end of the pushing plate 503. The clamping mechanism 5 is arranged on both sides of the front end of the bottom plate 103 to stabilize the sampling mechanism 4 during the sampling process to prevent it from affecting the sampling accuracy due to vibration or deviation. The clamping plate 501 is fixed on the bottom plate 103 to provide an installation basis for the cylinder 502. The cylinder 502 is connected to the pushing plate 503 through its front end piston rod. A sponge cover 504 is arranged at the center of the front end of the pushing plate 503 to contact with the sampling mechanism 4 and apply a stable clamping force. The two clamping plates 501 are respectively arranged on the bottom plate 10 3, a stable clamping frame is formed on both sides of the front end. This double-sided clamping design can more effectively disperse the clamping force, ensure stability during the clamping process, and reduce the possibility of shaking and offset. When the sampling device needs to be fixed on the soil surface, the cylinder 502 will receive the command, thereby driving the clamping plate 501 to move to both sides or the center, and its piston will push outward, driving the clamping plate 501 to expand outward until it contacts the sampling mechanism 4. The push plate 503 is directly connected to the piston rod of the cylinder 502, and its movement accuracy is directly affected by the control accuracy of the cylinder 502. By adjusting the position of the push plate 503 by the cylinder 502, accurate control of the clamping force can be achieved. The sponge cover 504 can enhance the softness and cushioning of the clamping. The softness and shock absorption of the sponge cover 504 effectively reduce the noise and vibration generated during the clamping process, thereby improving the working environment. At the same time, the clamping mechanism 5 can also guide the sampling mechanism 4.

[0044] The working principle of this embodiment is as follows: the sampler is placed in the soil area to be sampled, ensuring that the bracket 1 stands stably, and then the soil column 403 is assembled into the soil drilling column 402 and installed on the rotating rod 401 through threads. The operator sets the sampling depth through the control panel, and then the lifting motor 201 is started. The lifting motor 201 drives the lifting chain 202 to rotate, and the other end of the lifting chain 202 is connected to the support plate 102 through the sliding column 203, thereby driving the support plate 102 and the rotating mechanism 3 and the sampling mechanism 4 thereon to move up and down. At the same time, the lifting wheel 204 behind the support plate 102 slides in the slide groove 207 to provide guidance and support for the lifting process, ensuring the smooth lifting movement. During the descent, the rotating rod 401 drives the soil drilling column 402 to rotate synchronously through the threaded connection and drills downward into the soil. After descending to the appropriate position, the clamping mechanism 5 is started, and the multiple cylinders 502 inside the two clamping plates 501 are started, and the piston rod of the cylinder 502 pushes the push plate 503 to the soil drilling column 402, so that the pushing plates 503 on both sides are sleeved on the drilling column 402. When the drilling column 402 is drilled into the preset depth, the rotating mechanism 3 is started, and the rotating rod of the rotating motor 302 is connected to the rotating shaft 303 and rotates with the rotating shaft 303. The bottom of the rotating rod 401 is provided with a thread, and the thread is connected to the drilling column 402. The soil is drilled into the drilling column 402 through rotation and pushing motion, and the rotation is stopped and pressed downward. At this time, the soil extraction column 403 inside the drilling column 402 is also completed. Collect soil samples, then drive the lifting chain 202 through the lifting motor 201 to make the support plate 102 rise, the cylinder 502 in the clamping plate 501 drives the pushing plate 503 back to the original position, and the support plate 102 drives the sampling mechanism 4 to rise, waiting for the drill column 402 to leave the soil, the operator will take the soil column 403 out of the drill column 402, and transfer the soil sample to a special container for storage, and the sampling operation can be repeated many times to meet different soil environment surveys.
