Description

Technical Field

[0001] This application relates to the field of environmental sampling tools, specifically to a soil sampling tool. Background Technology

[0002] Soil environmental monitoring is a crucial foundational task for ecological environmental protection and pollution assessment, and one of its core components is on-site sampling. Collecting representative, undisturbed soil samples is essential for the accuracy and scientific rigor of subsequent laboratory analyses. However, in actual sampling operations, especially when dealing with soils with a certain degree of viscosity, traditional sampling tools often result in soil adhering to their inner walls after sampling. This makes it difficult to remove the soil sample from the sampling loop after collection, thus reducing the efficiency of the sampling process.

[0003] After sampling, monitoring personnel often need to use methods such as violent knocking, digging with auxiliary tools, or even damaging the sample structure to remove the columnar sample. This process is not only time-consuming and labor-intensive, greatly reducing the efficiency of sampling operations, but more seriously, it can easily cause the sample to be compressed, deformed, or broken, destroying the original structure of the soil and causing changes in its physicochemical properties, thereby directly affecting the authenticity and reliability of the monitoring data.

[0004] Soil sampling is an essential step in ecological and environmental monitoring. Its purpose is to obtain representative soil samples to accurately analyze the physical, chemical, and biological properties of the soil.

[0005] To further understand existing soil sampling devices, a search revealed Chinese Patent No. CN219178953U, which discloses a soil sampler, including a sampling rod. The sampling rod includes a handle and a sampling rod. The handle is installed on the top of the sampling rod, and rubber wear-resistant sleeves are installed at both ends of the handle. The sampling barrel also includes a sampling ring and a toothed ring. The sampling ring is installed at the bottom of the sampling rod, and the toothed ring is installed at the bottom of the sampling ring.

[0006] After exploration and analysis, the following drawbacks were found in the actual use of this patent: Although the patent facilitates the collection of soil at different depths by setting up a combined sampling structure, some soils are relatively moist and have a certain degree of stickiness. After sampling, the soil will stick to the inner wall of the sampling ring in the patent, making it difficult to pour the soil sample out of the sampling ring after sampling is completed, thereby reducing the efficiency of the sampling operation. Utility Model Content

[0007] To address the technical problem that clayey soil samples are difficult to pour out of the sampling loop after sampling, thus reducing the efficiency of the sampling operation, this application provides a soil sampling tool.

[0008] To achieve the above objectives, this application adopts the following technical solution: The soil sampling tool includes a connecting tube, a sampling tube fixedly connected to the lower end of the connecting tube, a connecting block fixedly installed at the upper end of the sampling tube, handles fixedly connected to both sides of the connecting block, an installation block fixedly installed inside the connecting tube, a lead screw rotatably installed inside the installation block, a handwheel coaxially fixedly connected to the top of the lead screw, the handwheel rotatably mounted on the sampling tube, a sliding plate threaded onto the external thread of the lead screw, a connecting rod fixedly connected below the sliding plate, and a push block fixedly installed at the bottom of the connecting rod, the push block slidably connected inside the sampling tube.

[0009] Furthermore, four sets of sliding grooves are provided on the inner wall of the connecting cylinder, and sliders are slidably connected in each of the four sets of sliding grooves. The sliders are fixedly connected to the circumferential surface of the sliding plate.

[0010] By adopting the above technical solution, the stability of the pusher block during movement is improved.

[0011] Furthermore, the bottom of the sampling tube is provided with a beveled tip, and a sleeve is provided on the outside of the sampling tube. Two sets of mounting plates are fixedly connected to the circumference of the sleeve. The two sets of mounting plates are symmetrically arranged, and each set of mounting plates is provided with a pedal. The pedal is provided with an anti-slip groove.

[0012] By adopting the above technical solution, it is easy to insert the sampling tube into the soil to collect samples.

[0013] Furthermore, the sleeve has two sets of locking holes, each set of which is threaded with a bolt rod, and a knob is fixedly installed on one side of the bolt rod.

[0014] By adopting the above technical solution, it is convenient to sample soil at different depths.

[0015] Furthermore, two sets of locking grooves are provided on the circumferential surface of the sampling tube, and the two sets of locking grooves are arranged symmetrically.

[0016] By adopting the above technical solution, the stability of the sleeve after locking is improved.

[0017] Furthermore, the sampling cylinder has scale lines etched on its circumferential surface, and these scale lines are positioned between two sets of locking grooves.

[0018] By adopting the above technical solution, the soil sampling depth can be precisely adjusted.

[0019] Furthermore, a storage block is fixedly installed on the circumferential surface of the connecting cylinder, the lower end of the storage block is provided with an opening, two sets of mounting seats are provided on the mounting plate, and the pedal is rotatably disposed between the two sets of mounting seats.

[0020] By adopting the above technical solution, the pedals can be stored away when not in use.

[0021] Furthermore, the storage block has a through hole that is compatible with the bolt rod, and the bottom of the pedal has a locking hole.

[0022] By adopting the above technical solution, the stability of the pedal after storage is improved.

[0023] Furthermore, a rotating shaft is rotatably mounted between the two sets of mounting seats, the pedal is fixedly mounted on the rotating shaft, and torsion springs are fixedly mounted on both sides of the pedal. One end of the torsion spring is fixedly connected to the mounting seat, and the torsion spring is sleeved on the outside of the rotating shaft.

[0024] By adopting the above technical solution, the pedals automatically unfold during use.

[0025] Furthermore, the handle is provided with an anti-slip sleeve on its outer surface, and the surface of the anti-slip sleeve is provided with anti-slip texture.

[0026] By adopting the above technical solutions, the anti-slip performance of the handle is improved.

[0027] To address the technical problem that clayey soil samples are difficult to remove from the sampling loop after sampling, thus reducing the efficiency of the sampling operation, this application has the following beneficial effects: The soil sampling tool of this application consists of a connecting tube, a sampling tube, a connecting block, an installation block, a screw, a handwheel, a sliding plate, a connecting rod, and a push block. After soil sampling is completed, the push block pushes the soil sample out of the sampling tube, which avoids sticky soil from sticking to the inner wall of the sampling tube and making it difficult to pour out, thus improving the convenience of soil sample removal and improving the efficiency of soil sampling operations. The position of the sleeve and pedal in the sampling tube can be adjusted by means of the sampling tube fitting, sleeve, mounting plate, pedal, locking hole, bolt rod, knob and scale line, which facilitates sampling of soil at different depths and improves the applicability and accuracy of the tool's sampling. By using a sleeve in conjunction with a mounting plate, mounting base, pivot, torsion spring, storage block, and through hole, the pedal, which is in a horizontal position, can be rotated to a vertical position and fixed in the storage block when the tool is not in use. This reduces the volume of the lower end of the tool, making it easier to transport and carry, and improving the tool's practicality.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] Referring to 1-6, this application discloses a soil sampling tool, which is mainly used for field sampling of soil in ecological environment monitoring.

[0034] like Figure 1-3As shown, this soil sampling tool includes a connecting tube 1, a sampling tube 2 fixedly connected to the lower end of the connecting tube 1, a connecting block 3 fixedly installed at the upper end of the sampling tube 2, handles 4 fixedly connected to both sides of the connecting block 3, an installation block 5 fixedly installed in the connecting tube 1, a lead screw 6 rotatably installed in the installation block 5, a handwheel 7 coaxially fixedly connected to the top of the lead screw 6, the handwheel 7 rotatably mounted on the sampling tube 2, a sliding plate 8 threadedly connected to the outside of the lead screw 6, a connecting rod 9 fixedly connected below the sliding plate 8, a push block 10 fixedly installed at the bottom of the connecting rod 9, and the push block 10 slidably connected in the sampling tube 2.

[0035] In use, place the tool on the soil to be sampled, and press down the connecting block 3, connecting cylinder 1, and sampling cylinder 2 by the handle 4 to insert the sampling cylinder 2 into the soil. The soil sample enters the sampling cylinder 2. After pulling the sampling cylinder 2 out of the soil, turn the handwheel 7 by hand. The handwheel 7 drives the lead screw 6 to rotate. The lead screw 6 pushes the slide plate 8 to move downward. The slide plate 8 drives the connecting rod 9 to move downward. The connecting rod 9 is slidably connected to the mounting block 5. The connecting rod 9 drives the push block 10 to move downward in the sampling cylinder 2. The push block 10 pushes the soil sample out of the sampling cylinder 2, avoiding sticky soil from sticking to the inner wall of the sampling cylinder 2 and making it difficult to pour out. This improves the convenience of soil sample removal and thus improves the efficiency of soil sampling operations.

[0036] Furthermore, four sets of sliding grooves 11 are provided on the inner wall of the connecting cylinder 1, and sliders 12 are slidably connected in each of the four sets of sliding grooves 11. The sliders 12 are fixedly connected to the circumferential surface of the sliding plate 8.

[0037] The slider 12, together with the slide groove 11, guides and limits the movement of the slide plate 8, preventing the slide plate 8 from flipping over when the lead screw 6 rotates, and improving the stability of the slide plate 8 during the up-and-down movement in the connecting cylinder 1. This, in turn, improves the stability of the push block 10 sliding in the sampling cylinder 2, and the push block 10 smoothly pushes the soil sample out of the sampling cylinder 2.

[0038] Furthermore, the bottom of the sampling cylinder 2 is provided with a beveled tip 21, and the outside of the sampling cylinder 2 is provided with a sleeve 13. Two sets of mounting plates 14 are fixedly connected to the circumferential surface of the sleeve 13. The two sets of mounting plates 14 are symmetrically arranged, and each set of mounting plates 14 is provided with a pedal 15. The pedal 15 is provided with an anti-slip groove 16.

[0039] The beveled tip 21 facilitates the insertion of the sampling tube 2 into the soil, making soil sampling easier for monitoring personnel. The sleeve 13 and mounting plate 14 provide installation conditions for the pedal 15. During the sampling process, the monitoring personnel press the pedal 15 in conjunction with the beveled tip 21 to smoothly insert the sampling tube 2 into the soil, further improving the convenience and practicality of sampling. The anti-slip groove 16 increases the friction between the foot and the pedal 15, preventing the foot from slipping on the pedal 15 during sampling and causing injury to the monitoring personnel, thus improving the safety of tool use.

[0040] Furthermore, the sleeve 13 has two sets of locking holes 17, and each set of locking holes 17 is threaded with a bolt rod 18. A knob 19 is fixedly installed on one side of the bolt rod 18.

[0041] Loosen the bolt rod 18, and the sleeve 13 slides freely on the sampling cylinder 2. After adjusting the sleeve 13 to a suitable position, tighten the bolt rod 18 so that one end of the bolt rod 18 is in close contact with the circumferential surface of the sampling cylinder 2. The friction between the bolt rod 18 and the circumferential surface of the sampling cylinder 2 will stably fix the sleeve 13 to the outside of the sampling cylinder 2. When the sampling cylinder 2 is inserted into the soil, the sleeve 13 and the pedal 15 will prevent the sampling cylinder 2 from being inserted further. Thus, by adjusting the position of the sleeve 13, the soil sampling depth of the sampling cylinder 2 can be controlled, which is convenient for sampling soil at different depths and improves the applicability of the tool. The knob 19 is designed to facilitate the rotation of the bolt rod 18.

[0042] Furthermore, two sets of locking grooves 29 are provided on the circumferential surface of the sampling cylinder 2, and the two sets of locking grooves 29 are arranged symmetrically.

[0043] The locking groove 29 changes the contact between one end of the bolt rod 18 and the arc surface of the sampling cylinder 2 to the flat contact between one end of the bolt rod 18 and the locking groove 29, increasing the contact area and thus improving the fixing effect of the bolt rod 18 on the sleeve 13. This makes the fixed sleeve 13 and the pedal 15 more stable and improves the stability of the tool during use.

[0044] Furthermore, the sampling cylinder 2 has scale lines 20 etched on its circumferential surface, and the scale lines 20 are located between the two sets of locking grooves 29.

[0045] With the scale line 20 set, it is more intuitive to move the sleeve 13 when adjusting the soil sampling depth, which can accurately control the soil sampling depth and improve the accuracy of tool sampling.

[0046] To further explain, a storage block 25 is fixedly installed on the circumferential surface of the connecting cylinder 1. The storage block 25 has an opening at its lower end. Two sets of mounting seats 22 are provided on the mounting plate 14. The pedal 15 is rotatably positioned between the two sets of mounting seats 22.

[0047] When the tool is not in use, rotate pedal 15 to a vertical position, push sleeve 13 and pedal 15 upwards, so that the upper end of pedal 15 is inserted into storage block 25 for storage (as shown in the attached diagram). Figure 1 As shown, reducing the volume of the lower part of the tool facilitates transportation and carrying, and improves the tool's practicality.

[0048] Furthermore, the storage block 25 has a through hole 26, which is compatible with the bolt rod 18, and the bottom of the pedal 15 has a locking hole 27.

[0049] Before storing, unscrew the bolt rod 18 from the sleeve 13. At this time, the sleeve 13 can slide freely outside the sampling cylinder 2. Slide the sleeve 13 upward so that the upper end of the pedal 15 is inserted into the storage block 25. Then screw the bolt rod 18 into the through hole 26 so that part of the bolt rod 18 enters the locking hole 27. The bolt rod 18, together with the locking hole 27, restricts the pedal 15, so that the pedal 15 is stably stored in the storage block 25, preventing the pedal 15 from accidentally sliding out of the storage block 25 during tool transportation and carrying, and further improving the practicality of the tool.

[0050] To further explain, such as Figure 4 and Figure 5 As shown, a rotating shaft 23 is rotatably mounted between two sets of mounting bases 22. The pedal 15 is fixedly mounted on the rotating shaft 23. Torsion springs 24 are fixedly mounted on both sides of the pedal 15. One end of the torsion spring 24 is fixedly connected to the mounting base 22. The torsion spring 24 is sleeved on the outside of the rotating shaft 23.

[0051] When pedal 15 is rotated to a vertical position for storage, torsion spring 24 is in a torsional state. When tools are needed, after the upper end of pedal 15 is removed from storage block 25, the torsional spring 24 returns to its initial state, causing pedal 15 to reverse to a horizontal position (e.g., ...). Figure 6 As shown), the mounting plate 14 limits the pedal 15, so that the pedal 15 can rotate to a horizontal position at most, making it easier to insert the sampling tube 2 into the soil by pressing the pedal 15.

[0052] Furthermore, the outer fixing sleeve of the handle 4 is provided with an anti-slip sleeve 28, and the surface of the anti-slip sleeve 28 is provided with anti-slip texture.

[0053] During the sampling process, the connecting tube 1 and the sampling tube 2 are stabilized by gripping the handle 4 with both hands, so that the sampling tube 2 can be smoothly inserted into the soil. The anti-slip sleeve 28 is made of rubber to reduce hand wear during the sampling process and improve the stability of the handle 4 when gripping and the comfort of the tool during use.

[0054] For specific operation, please refer to the following steps: Unscrew the bolt rod 18 on the storage block 25 to release the bolt rod 18 from restricting the pedal 15. Slide the sleeve 13 downwards, and the torsion spring 24 will cause the pedal 15 to reverse to a horizontal position. By observing the scale line 20, slide the sleeve 13 to a suitable position on the sampling cylinder 2. Screw the bolt rod 18 into the locking hole 17 and tighten it, so that one end of the bolt rod 18 is in close contact with the locking groove 29 of the sampling cylinder 2, thereby fixing the sleeve 13 and the pedal 15 in place. Place the sampling tube 2 at a suitable position outside the sample tube 2 on the soil to be sampled. Stabilize the connecting tube 1 and the sampling tube 2 with the handle 4, and then press the pedal 15 with your foot to insert the sampling tube 2 into the soil. The soil sample enters the sampling tube 2. After pulling the sampling tube 2 out of the soil, turn the handwheel 7 by hand. The handwheel 7 drives the screw 6 to rotate. The screw 6 pushes the slide plate 8. The slide plate 8 drives the connecting rod 9 and the push block 10 to move downward in the sampling tube 2, pushing the soil sample out of the sampling tube 2.

[0055] All standard parts used in this application can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.

In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0056] In summary, this soil sampling tool, as a novel field sampling instrument, effectively solves the problem of adhesion in cohesive soils, enabling the complete and convenient extraction of samples. It also features precise and adjustable sampling depth control to ensure sampling consistency. While maintaining sampling quality, it simplifies operation procedures, reduces labor intensity, and improves the efficiency of a single sampling session. Furthermore, the tool itself should be structurally sound, robust, durable, and portable to adapt to complex and diverse field working environments. This soil sampling tool has significant practical value.
