Description

Technical Field

[0001] The present invention relates to the technical field of soil remediation, and particularly to a soil sample collection device for soil remediation. Background Art

[0002] Soil remediation refers to using physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in the soil, reducing their concentration to an acceptable level, or converting toxic and harmful pollutants into harmless substances. In order to remediate the soil targeted, it is necessary to use a special soil sample collection device to collect a certain amount of soil samples for research.

[0003] A Chinese patent with the publication number CN219657201U discloses a soil sample collection device for soil remediation, including a bracket. A threaded column is threadedly connected to the bracket. The top end of the threaded column is fixedly connected to a turning handle. The bottom end of the threaded column is fixedly connected to a cylinder. The bottom end of the cylinder is fixedly connected to a round plate. A collection plate is provided below the round plate. The collection plate is used for sampling soil, and an inverted plate is fixedly connected to the inner wall of the collection plate. Through the structural design of the four collection plates, when it is necessary to take out the soil, rotate the rotating sleeve. The rotating sleeve moves downward, and the rotating sleeve presses the vertical column downward. The vertical column presses the folding plate to rotate around the rotating shaft through the spherical ball. The folding plate can drive the collection plate to rotate, so that the four collection plates open, and the soil will fall off, realizing the function of quickly and conveniently taking out the soil, and solving the problem that the current soil sample collection device is inconvenient to take out the soil from the sampling cylinder.

[0004] However, the above solution has some significant drawbacks. First, this design requires manually turning the turning handle to make the threaded column guide the collection plate to move towards the ground surface. This manual operation is not only inefficient but also increases the labor cost during use. In addition, manually turning the turning handle may cause inconvenience to the operator during operation, especially in an environment with limited space or complex equipment, which further reduces the overall operation convenience of the system. Summary of the Invention

[0005] This application provides a soil sample collection device for soil remediation, which has the function of efficiently, stably, and conveniently extracting soil samples.

[0006] A soil sample collection device for soil remediation provided by this application adopts the following technical solutions: A soil sample collection device for soil remediation includes a frame. An installation plate is provided on the frame. A first cylinder and a guide rail are provided on the installation plate. The output end of the first cylinder is connected to a fixing workpiece. A guide wheel matching the guide rail is provided on the fixing workpiece. A fixing sleeve is fixedly installed on the fixing workpiece. A sampling rod for extracting soil samples is provided inside the fixing sleeve.

[0007] By adopting the above technical solution, the first cylinder serves as a power source. Due to the action of gas pressure, its piston undergoes displacement, thereby driving the fixed sleeve and the sampling rod inside it to move up and down; the guide rail provides a stable sliding path for the fixed sleeve and the sampling rod, ensuring that it can achieve smooth and linear movement during the sampling process, reducing the risk of deviating from the target position; by combining the driving mechanism of the first cylinder and the supporting effect of the guide rail, an efficient, stable and easy-to-operate soil sample extraction system is constructed; this design significantly improves the quality and efficiency of soil research and investigation, and can better meet the needs of soil sampling.

[0008] Preferably, a connecting seat and a second cylinder are fixedly installed on the frame. The first cylinder is rotatably arranged between the frame, and the output end of the first cylinder is hinged between the back of the placement plate, and the connecting seat is rotatably connected to the bottom of the placement plate.

[0009] By adopting the above technical solution, through the drive of the second cylinder, the generated power acts on the connecting seat; by precisely controlling the telescopic movement of the cylinder, the connecting seat can rotate around the rotating shaft, thereby driving the placement plate to complete the flipping action; the connecting seat and the bottom of the placement plate are connected by a rotating shaft, and this design endows the placement plate with multiple degrees of freedom of flipping, enabling the operator to flexibly adjust the sampling or processing direction according to specific needs; this structural design effectively improves the flexibility and adaptability of the operation and provides support for diverse application scenarios.

[0010] Preferably, a drill pipe is rotatably arranged inside the sampling rod. A toothed ring is provided on the outer ring at the top of the drill pipe. A fixing plate is provided on the outer side of the sampling rod, and a driving motor is provided on the fixing plate. The output end of the driving motor is connected with a gear, and the gear meshes with the toothed ring.

[0011] By adopting the above technical solution, when the driving motor is started, the rotational power generated by the motor is transmitted to the toothed ring through the gear, causing the toothed ring to rotate; since the toothed ring is connected to the drill pipe, the rotation of the toothed ring directly drives the drill pipe to perform corresponding rotational movement inside the sampling rod; the rapid rotation of the drill pipe can effectively penetrate the soil, thereby significantly shortening the sampling time and improving the operation efficiency; the design of this system optimizes the soil sampling process and improves the overall operation performance.

[0012] Preferably, a probe is provided at the bottom of the drill pipe.

[0013] By adopting the above technical solution, it is used to quickly insert into the ground surface, thereby facilitating the improvement of sampling efficiency.

[0014] Preferably, the probe includes a mounting sleeve. A plurality of grab plates that can rotate and open and close are provided at the bottom of the mounting sleeve, and a driving member for driving the grab plates is provided on the mounting sleeve.

[0015] By adopting the above technical solution, when the driving member is activated, the grab plates expand outwards, thereby expanding the sampling range and optimizing the soil grabbing effect in loose soil layers; when it is necessary to switch to grabbing sandy or silt-like soil, the grab plates effectively capture soil samples through the closing action; this design flexibly adjusts the sampling strategy to meet the requirements of different soil types, improving the accuracy and efficiency of sampling.

[0016] Preferably, the grab plates are arc-shaped petal structures. When several grab plates are in the closed state, the several grab plates in the closed state form a drill bit with a conical structure at the bottom.

[0017] By adopting the above technical solution, the arc-shaped petal grab plates form a conical drill bit structure when closed. This design, combined with the movement of the drill pipe, effectively improves its performance when penetrating the soil; this structure not only optimizes the soil drilling process but also ensures the sampling efficiency and accuracy under different soil conditions.

[0018] Preferably, at least two slicing blades are provided on the outer surface of the grab plates, and the slicing blades are inclined with respect to the grab plates.

[0019] By adopting the above technical solution, the slicing blades are designed to be inclined, enabling efficient cutting when drilling or grabbing soil and other substances; the setting of the inclination angle helps the blades cut into the material more smoothly, thus significantly improving the cutting efficiency; in addition, the inlet angle of the inclined blades is smaller, which increases the contact area between the blades and the soil or other materials, thereby accelerating the cutting speed and reducing the time required for drilling; this design effectively improves the overall performance and efficiency of the operation.

[0020] Preferably, the driving member includes a plurality of first hinge seats and second hinge seats provided on the outer ring of the mounting sleeve. A third cylinder is hinged on the first hinge seat, and the output end of the third cylinder is hinged to the grab plate, and the top end of the grab plate is rotatably arranged with the second hinge seat.

[0021] By adopting the above technical solution, driven by the third cylinder, the grab plate can rotate around the second hinge seat; the first hinge seat and the second hinge seat serve as fulcrums, and the third cylinder and the grab plate are hinged to enable the grab plate to rotate at a specific fulcrum; the hinged design between the output end of the third cylinder and the grab plate enables the grab plate to swing freely around the second hinge seat under the driving action of the cylinder; the third cylinder generates a driving force through its telescopic movement: when the cylinder extends, the grab plate is lifted; when the cylinder retracts, the grab plate moves downward; the force generated by this displacement causes the grab plate to rotate around the hinge seat, thereby achieving precise control of the inclination angle and position of the grab plate.

[0022] Preferably, a support plate is fixedly installed on the frame. A cleaning water tank is provided on the support plate. A water pump is arranged inside the cleaning water tank. The output end of the water pump is connected to a water outlet pipe. The output end of the water outlet pipe is connected to a flushing nozzle, and the water flow jet orifice of the flushing nozzle faces the drill pipe and the probe.

[0023] By adopting the above technical solution, the cleaning water tank is used to store cleaning water to form a centralized water source; the water pump is installed inside the cleaning water tank. When cleaning is required, the water pump is started to draw water from the tank and convey it to the water outlet pipe; the drawn water is then transmitted to the nozzle and directly sprayed onto the drill pipe and the probe through high-pressure spraying to achieve an effective cleaning purpose; the design of this system can ensure the high efficiency and reliability of the cleaning process and guarantee the good operating state of the equipment.

[0024] Preferably, a push handle is provided on the frame. Base plates are fixedly installed on both sides of the frame, and driving wheels are provided on the base plates.

[0025] By adopting the above technical solution, with the push handle and the driving wheels, it is convenient to move the device to a suitable position.

[0026] In summary, the present application has the following beneficial effects: 1. The first cylinder serves as a power source. Due to the action of gas pressure, its piston undergoes displacement, thereby driving the fixed sleeve and the sampling rod inside it to move up and down; the guide rail provides a stable sliding path for the fixed sleeve and the sampling rod, ensuring that they can move smoothly and linearly during the sampling process and reducing the risk of deviating from the target position; by combining the driving mechanism of the first cylinder and the supporting effect of the guide rail, an efficient, stable and easy-to-operate soil sample extraction system is constructed; this design significantly improves the quality and efficiency of soil research and investigation and can better meet the requirements of soil sampling.

Detailed implementation manners

[0030] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content. Embodiment

[0031] The present invention discloses a sample collection device for soil remediation, as Figure 1 shown, including a frame 1. A pusher 2 is provided on the frame 1. The design of the pusher 2 enables the operator to conveniently push the device, ensuring that the equipment can move smoothly on the soil surface for sampling or remediation operations; Base plates 3 are fixedly installed on both sides of the frame 1. Driving wheels 4 are provided on the base plates 3. The driving wheels 4 are responsible for moving on the soil; Tires are provided on the outer surface of the driving wheels 4. A number of strip-shaped protrusions 5 are evenly provided on the surface of the tires. The design of the strip-shaped protrusions 5 can increase the contact area between the tires and the ground and improve the friction force; This means that during driving, the tires can better grip the ground and reduce slipping; Moreover; The shape and design of the strip-shaped protrusions 5 can make the tires more flexible under different terrains and soil conditions, be able to adapt to uneven surfaces, and provide better traction.

[0032] As Figure 1As shown, a mounting plate 6 is provided on the frame 1. A first cylinder 7 and a guide rail 8 are fixedly installed on the mounting plate 6. There are two guide rails 8, and the first cylinder 7 is located between the two guide rails 8. The output end of the first cylinder 7 is connected to a fixing workpiece 9. A guide wheel 10 matching the guide rail 8 is provided on the fixing workpiece 9. A fixing sleeve 11 is fixedly installed on the fixing workpiece 9. A sampling rod 12 for extracting soil samples is provided inside the fixing sleeve 11.

[0033] As Figure 1 shown, the first cylinder 7 serves as a power source. Through the pressure of the gas, the piston of the first cylinder 7 moves, thereby pushing the fixing sleeve 11 and the sampling rod 12 inside it up and down. The guide rail 8 provides a stable sliding path for the fixing sleeve 11 and the sampling rod 12, ensuring that they can move smoothly and linearly during the sampling process and are not easily deviated from the target position. When the first cylinder 7 is activated, the sampling rod 12 enters the soil downward through the fixing sleeve 11 to complete the extraction of soil samples. Using the guide rail 8 system can ensure the verticality and stability of the sampling rod 12, avoid deviation during the sampling process, and improve the accuracy and repeatability of sampling.

[0034] As Figure 1 shown, generally speaking, the design of this sampling device provides an efficient, stable and easy-to-operate soil sample extraction solution through the driving of the first cylinder 7 and the support of the guide rail 8, which helps to improve the quality and efficiency of soil research and investigation.

[0035] As Figure 1 and Figure 2 shown, a connecting seat 13 and a second cylinder 14 are fixedly installed on the frame 1. The first cylinder 7 is rotatably arranged between the first cylinder 7 and the frame 1. The output end of the first cylinder 7 is hinged between the back of the mounting plate 6. The connecting seat 13 and the bottom of the mounting plate 6 are rotatably connected through a rotating shaft 15. Through the driving of the second cylinder 14, the power of the second cylinder 14 acts on the connecting seat 13. By controlling the telescopic movement of the cylinder, the connecting seat 13 rotates around the rotating shaft 15, thereby guiding the mounting plate 6 to flip. The connecting seat 13 and the bottom of the mounting plate 6 are connected through the rotating shaft 15, giving the mounting plate 6 multiple degrees of freedom of flipping, so that the operator can perform sampling or processing in different directions according to needs.

[0036] As Figure 1 and Figure 2As shown, therefore, the above structure allows the placement plate 6 to flip around the rotating shaft 15, enabling the convenient adjustment of the sampling or operation angle to adapt to different working environments and requirements; moreover, the flip design helps reduce the floor area of the equipment. Especially in an environment with limited space, it can be operated and arranged more effectively; through this flip mechanism, the equipment can switch between different functions faster, improving the overall operation efficiency; for example, it can conveniently switch from one sampling action to another, saving the time for reorganizing the machine.

[0037] As Figure 1 and Figure 2 As shown, a drill pipe 16 is rotatably arranged inside the sampling rod 12. A toothed ring 17 is fixedly installed on the outer circle at the top of the drill pipe 16. A fixed plate 18 is fixedly installed on the outer side of the sampling rod 12. A driving motor 19 is fixedly installed on the fixed plate 18. The output end of the driving motor 19 is connected with a gear 20. The gear 20 meshes with the toothed ring 17. By the driving motor 19, the gear 20 drives the toothed ring 17 to rotate, and then drives the drill pipe 16 to rotate inside the sampling rod 12.

[0038] As Figure 1 and Figure 2 As shown, when the driving motor 19 is started, the rotational power output by the motor is transmitted to the toothed ring 17 through the gear 20, causing the toothed ring 17 to rotate; since the toothed ring 17 is connected to the drill pipe 16, the rotation of the toothed ring 17 directly drives the drill pipe 16 to rotate inside the sampling rod 12; the rotation of the drill pipe 16 can quickly enter the soil, thereby reducing the sampling time and improving the operation efficiency; and the rotating drill pipe 16 can effectively reduce the frictional resistance with the soil during the drilling process, making it easier to penetrate different types of soil; this device can work in various soil types (such as clay, sandy soil, rocky soil, etc.), has strong adaptability, and is suitable for the exploration needs of various soil sites.

[0039] As Figure 2 and Figure 3 As shown, a probe 21 is provided at the bottom of the drill pipe 16. The probe 21 includes a mounting sleeve 2101. The mounting sleeve 2101 is in communication with the drill pipe 16 and is detachably arranged. The mounting sleeve 2101 is directly in communication with the drill pipe 16, realizing the stable installation of the probe 21 during the drilling process.

[0040] As Figure 3As shown, several rotatable and expandable grab plates 2102 are provided at the bottom of the mounting sleeve 2101. The grab plates 2102 are equally angularly distributed around the central axis of the mounting sleeve 2101. Each grab plate 2102 is independent and rotatable, having a certain degree of flexibility. This design enables the grab plates 2102 to open and close in different working modes, so as to adapt to the sampling requirements of different soils. A driving member 2103 for driving the grab plates 2102 is provided on the mounting sleeve 2101. When the driving member 2103 is activated, the grab plates 2102 open outward to expand the sampling range, and can better grab soil in loose soil layers. When the need switches to grabbing sandy or muddy soil, the grab plates 2102 close to facilitate capturing soil samples.

[0041] As Figure 3 shown, during the sampling process, first place the probe 21 into the predetermined soil layer, and the driving member 2103 controls the movement of the grab plates 2102, and adjusts according to the soil type and sampling requirements to ensure the best sampling effect. By opening and closing the grab plates 2102, it can adapt to different soil types and structures, and can effectively cope with various situations such as loose, viscous or liquid soil, improving the versatility of the device. The design of the grab allows the operator to precisely control the grabbing of soil blocks. Especially in sandy and muddy soils, it can effectively reduce disturbance and improve the accuracy and representativeness of sampling.

[0042] As Figure 3 and Figure 4 shown, the grab plate 2102 is an arc-shaped petal structure. When several grab plates 2102 are in the closed state, several grab plates 2102 in the closed state form a drill bit with a conical structure at the bottom. The arc-shaped petal grab plates 2102 present a conical drill bit structure when closed, which can be combined with the movement of the drill pipe 16 to ensure effectiveness when drilling into the soil. The conical structure can effectively help its penetration and cutting in the soil, reduce the resistance of the soil, and make the drilling process smoother. Moreover, the conical structure can gradually cut and compress the surrounding soil during drilling, reduce soil disturbance, so that the sampled soil is more complete and unaffected.

[0043] As Figure 3 and Figure 4 shown, at least two slicing blades are provided on the outer surface of the grab plate 2102. The slicing blades are inclined with respect to the grab plate 2102. Through the inclined design of the slicing blades, effective cutting can be carried out when drilling or grabbing soil or other substances. The inclined angle helps the blades to more easily cut into the material, improving the cutting efficiency. Since the inlet angle of the inclined blades is smaller, it can increase the contact area with the soil or other materials, thereby accelerating the cutting speed and reducing the drilling time.

[0044] As Figure 3 and Figure 4 shown, the driving member 2103 includes a plurality of first hinge seats 210301 and second hinge seats 210302 provided on the outer circumference of the mounting sleeve 2101. A third cylinder 210303 is hinged on the first hinge seat 210301. An articulated setting is provided between the output end of the third cylinder 210303 and the grab plate 2102. A rotational setting is provided between the top end of the grab plate 2102 and the second hinge seat 210302.

[0045] As Figure 3 and Figure 4 shown, through the third cylinder 210303, the grab plate 2102 is rotated around the second hinge seat 210302. The first hinge seat 210301 and the second hinge seat 210302 serve as fulcrums, and the third cylinder 210303 and the grab plate 2102 are connected by an articulated manner, so that the grab plate 2102 rotates at a specific fulcrum; the articulated connection between the output end of the third cylinder 210303 and the grab plate 2102 allows the grab plate 2102 to swing freely around the second hinge seat 210302 when driven by the cylinder; the third cylinder 210303 generates a driving force through telescopic movement; when the cylinder extends, the grab plate 2102 is lifted upward; when the cylinder retracts, the grab plate 2102 moves downward; the force generated by this displacement causes the grab plate 2102 to rotate around the hinge seat; thus, the tilt angle and position of the grab plate 2102 can be accurately controlled.

[0046] As Figure 2 shown, a support plate 22 is fixedly installed on the frame 1. A cleaning water tank 23 is provided on the support plate 22. A water pump is provided inside the cleaning water tank 23. The output end of the water pump is connected to a water outlet pipe 25. The output end of the water outlet pipe 25 is connected to a flushing nozzle 24. The water flow jet orifice of the flushing nozzle 24 faces the drill pipe 16 and the probe 21; As Figure 2 shown, the cleaning water tank 23 is used to store cleaning water to form a centralized water source; the water pump is installed inside the cleaning water tank 23. When cleaning is required, the water pump is started to extract the water in the tank and convey it to the water outlet pipe 25; and the extracted water is transmitted to the nozzle; the water is directly sprayed onto the drill pipe 16 and the probe 21 by high-pressure spraying to achieve the cleaning purpose.

[0047] As Figure 2As shown, by directly flushing the drill pipe 16 and the probe 21 with high-pressure water flow, the dirt, residues, and dust on their surfaces can be efficiently removed, keeping the equipment clean. The clean drill pipe 16 and probe 21 can maintain a good working state, improve the efficiency during the drilling process, and reduce the obstruction caused by dirt. Moreover, regular cleaning can prevent corrosion and other damages caused by dirt accumulation, thereby extending the service life of the drill rig and the probe 21.

[0048] Working principle: Before use, the user first moves the device to the sampling point position through the pusher 2 and the drive wheel 4, and then starts the first cylinder 7. The first cylinder 7 serves as a power source, and through the pressure of the gas, the piston of the first cylinder 7 moves, thereby pushing the fixed sleeve 11 and the sampling rod 12 inside it up and down. The guide rail 8 provides a stable sliding path for the fixed sleeve 11 and the sampling rod 12, ensuring that they can move smoothly and linearly during the sampling process and are not easily deviated from the target position. When the first cylinder 7 is activated, the sampling rod 12 enters the soil downward through the fixed sleeve 11 to complete the extraction of the soil sample.

[0049] When encountering silt or sandy soil, start the drive motor 19. When the drive motor 19 starts, the rotational power output by the motor is transmitted to the gear ring 17 through the gear 20, causing the gear ring 17 to rotate. Since the gear ring 17 is connected to the drill pipe 16, the rotation of the gear ring 17 directly drives the drill pipe 16 to rotate inside the sampling rod 12. The rotation of the drill pipe 16 can quickly enter the soil, thereby reducing the sampling time and improving the operation efficiency. And the rotating drill pipe 16 can effectively reduce the frictional resistance with the soil during the drilling process, making it easier to penetrate different types of soil. This device can work in various soil types (such as clay, sandy soil, rocky soil, etc.), has strong adaptability, and is suitable for the exploration needs of various soil sites.

[0050] During the sampling process, first place the probe 21 into the predetermined soil layer, and the drive member 2103 controls the movement of the grab plate 2102, adjusts according to the soil type and sampling requirements to ensure the best sampling effect. By opening and closing the grab plate 2102, it can adapt to different soil types and structures, and can effectively cope with various situations such as loose, viscous, or liquid soil, improving the versatility of the device. The design of the grab allows the operator to precisely control the grasping of the soil mass, especially in sandy and silt-like soils, which can effectively reduce disturbance and improve the accuracy and representativeness of sampling.

[0051] After the sampling is completed, start the water pump to extract the water in the water tank and convey it to the outlet pipe 25. And the extracted water is transmitted to the flushing nozzle 24. Use high-pressure spraying to directly spray the water onto the drill pipe 16 and the probe 21 to achieve the cleaning purpose.

[0052] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
