Abstract
Description
Technical Field
[0001] This invention relates to the field of forestry ecological protection technology, and in particular to a sampling device for forestry ecological protection. Background Technology
[0002] Forestry ecological protection is a systematic project guided by the theory of sustainable development, focusing on forest ecosystems. Through scientific management, resource conservation, and ecological restoration, it coordinates the relationship between humans and nature, maintains ecological functions such as biodiversity, soil and water conservation, and climate regulation, and ultimately achieves a unified ecological, economic, and social benefit. Its core lies in ensuring the stable growth of total forest resources and preventing irreversible ecological damage caused by development activities. This is achieved through measures such as restricting commercial logging, establishing nature reserves, and replanting trees to maintain forest ecological balance. The nutrient levels, pH, and organic matter content of forest soil directly affect tree growth. For example, by collecting soil samples from the topsoil layer (0-20 cm deep), the dynamic changes in nutrients such as nitrogen, phosphorus, and potassium can be monitored, providing a basis for developing scientific fertilization strategies. If a forest area has severe potassium deficiency, timely potassium fertilizer supplementation after sampling and analysis can significantly improve tree disease resistance and growth rate.
[0003] Traditional soil samplers typically require manual sampling after drilling through layers. Each sampling layer necessitates repeated insertion, extraction, and tool cleaning procedures. During extraction, soil samples from different depths may mix due to residue on the tool's inner wall or external pressure. When the auger is raised, upper soil layers may slip into lower samples, leading to data distortion. After sampling, samples must be manually transferred to storage containers, exposing them to the external environment and making them susceptible to contaminants. Therefore, a sampling device for forestry ecological protection is proposed. Summary of the Invention
[0004] The purpose of this invention is to solve the problems of existing technologies, such as the need for manual sampling after drilling layer by layer, the possibility of soil samples from different depths being mixed due to residue on the inner wall of the tool or external pressure, the possibility of upper soil slipping into lower samples during the lifting of the auger, leading to data distortion, and the need for manual transfer to storage containers after sampling, which exposes the samples to the external environment and easily introduces pollutants. Therefore, this invention proposes a sampling device for forestry ecological protection.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sampling device for forestry ecological protection includes a support plate, a U-shaped plate mounted on the upper part of the support plate, a driving device mounted on the upper part of the U-shaped plate, and a sampling assembly on the support plate. The sampling assembly includes a sampling rod detachably connected to the bottom of the support plate, multiple U-shaped plates movably connected to the inner side of the sampling rod, a square plate movably connected to the inner side of the sampling rod, multiple round rods slidably disposed on the side of the square plate, a collection box mounted on the end of the round rods, a pressure block slidably disposed at the bottom of the support plate, and a driving unit disposed at the bottom of the support plate. The collection box is movably connected to the U-shaped plates. After the driving device is started, it drives the sampling rod to drill into the soil through the support plate. The driving unit causes the pressure block to squeeze and compress the square plate. The square plate pushes the collection box to move to the outside of the sampling rod for sampling through the multiple round rods. After sampling, the collection box enters the inner side of the sampling rod and the opening of the collection box is blocked by a baffle. The sampling position of the collection box is changed by sliding the U-shaped plates up and down. A storage box is movably connected to the inner side of the collection box.
[0006] The above technical solution further includes: A movable plate is slidably disposed on the inner side of the sampling rod, and the spiral plate is installed on the side of the movable plate.
[0007] The inner side of the U-shaped plate has an opening groove, the size of which is adapted to the size of the collection box. When the collection box is inside the opening groove, the baffle is in contact with the upper end of the collection box, and the baffle blocks the opening of the collection box, thus sealing and storing the soil.
[0008] The drive unit includes a support plate with a first threaded rod threadedly connected to its inner side. A push plate is rotatably connected to the end of the first threaded rod. A first telescopic rod is installed on the upper part of the push plate. The end of the first telescopic rod away from the push plate is fixedly connected to the support plate. Rotating the first threaded rod causes the push plate to move downward. When the push plate moves downward, it squeezes the inclined surface of the pressure block.
[0009] The drive unit also includes a first ring installed at the bottom of the support plate, a second telescopic rod installed on the inner side of the first ring, the other end of the second telescopic rod being fixedly connected to the pressure block, the pressure block being slidably connected to the first ring, and when the push plate moves down, it squeezes the inclined surface of the pressure block. After being squeezed by the push plate, the pressure block moves to the outside of the first ring and squeezes the square plate.
[0010] The inner wall of the sampling rod is equipped with a fourth telescopic rod, and the other end of the fourth telescopic rod is fixedly connected to the square plate, which is located on the movement trajectory of the pressure block.
[0011] The inner wall of the sampling rod is equipped with a third telescopic rod, and the other end of the third telescopic rod is equipped with a movable frame. A connecting rod is rotatably connected to the side of the movable frame. The connecting rod is threadedly connected to the sampling rod. Multiple locking plates are installed on the side of the movable frame. The locking plates have an arc-shaped cross-section and fit against the movable plates. The locking plates are made of rubber. The locking plates press the movable plates to lock the positions of the U-shaped plate and the collection box.
[0012] The square plate has multiple sliding grooves on its side. A sliding block is slidably disposed on the inner side of the sliding groove. The side of the sliding block is fixedly connected to the round rod. The round rod moves along the sliding groove through the sliding block.
[0013] A second ring is installed at the bottom of the support plate, and a limiting groove is formed on the inner side of the second ring. A semi-circular rod is installed on the outer side of the sampling rod.
[0014] The sampling rod has a first square groove on its side and a second square groove on the inner side of the second ring. A fixed block is slidably disposed on the inner side of the second square groove. A movable rod is installed on the side of the fixed block and is movably connected to the second ring. A spring is installed on the side of the fixed block near the movable rod. The end of the spring away from the fixed block is fixedly connected to the inner wall of the second square groove. The detachable sampling rod can store soil in real time, and then the next sampling rod can be replaced to continue sampling.
[0015] The present invention has the following beneficial effects: 1. In this invention, by setting up a sampling component to drive the collection box to unfold outward and insert into the soil, multi-layer simultaneous sampling is achieved, which significantly improves sampling efficiency. It is especially suitable for large-scale and multi-depth sampling tasks. When the collection box retracts, the baffle automatically blocks the opening to form a closed space, which prevents soil samples from different depths from mixing or external pollutants from entering, thus ensuring sample purity. In addition, each collection box has a built-in storage box, which facilitates the complete removal of soil.
[0016] 2. In this invention, while achieving stratified sampling, the sampling position of the collection box can be changed by sliding the spiral plate up and down, so as to achieve independent adjustment of the sampling depth of each layer. In areas with abrupt changes in soil texture, the sampling point can be accurately located, avoiding sample mixing. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1 like Figures 1-10As shown, the sampling device for forestry ecological protection proposed in this invention includes a support plate 1, a U-shaped plate 2 installed on the upper part of the support plate 1, a driving device 3 installed on the upper part of the U-shaped plate 2, and a sampling assembly on the support plate 1. The sampling assembly includes a sampling rod 10 detachably connected to the bottom of the support plate 1, multiple U-shaped plates 19 movably connected to the inner side of the sampling rod 10, a square plate 11 movably connected to the inner side of the sampling rod 10, multiple round rods 14 slidably arranged on the side of the square plate 11, a collection box 15 installed at the end of the round rods 14, and a pressure block 9 slidably arranged at the bottom of the support plate 1. The drive unit at the bottom is movably connected between the collection box 15 and the U-shaped plate 19. After the drive device 3 is started, it drives the sampling rod 10 to drill into the soil through the support plate 1. The drive unit causes the pressure block 9 to squeeze and press the square plate 11. The square plate 11 pushes the collection box 15 to move to the outside of the sampling rod 10 for sampling through multiple round rods 14. After sampling, the collection box 15 enters the inside of the sampling rod 10 and the opening of the collection box 15 is blocked by the baffle 17. The sampling position of the collection box 15 is changed by sliding the U-shaped plate 19 up and down. The storage box 18 is movably connected to the inside of the collection box 15.
[0021] An opening groove 16 is provided on the inner side of the U-shaped plate 19. The size of the opening groove 16 is adapted to the size of the collection box 15. When the collection box 15 is inside the opening groove 16, the baffle 17 fits against the upper end of the collection box 15. The baffle 17 blocks the opening of the collection box 15 and seals the soil for storage.
[0022] The drive unit includes a support plate 1 with a first threaded rod 7 threadedly connected to the inner side. The end of the first threaded rod 7 is rotatably connected to a push plate 6. A first telescopic rod 5 is installed on the upper part of the push plate 6. The end of the first telescopic rod 5 away from the push plate 6 is fixedly connected to the support plate 1. Rotating the first threaded rod 7 causes the push plate 6 to move downward. When the push plate 6 moves downward, it squeezes the inclined surface of the pressure block 9.
[0023] The drive unit also includes a first ring 4 installed at the bottom of the support plate 1, a second telescopic rod 8 installed on the inner side of the first ring 4, the other end of the second telescopic rod 8 being fixedly connected to the pressure block 9, the pressure block 9 being slidably connected to the first ring 4, when the push plate 6 moves down, it squeezes the inclined surface of the pressure block 9, and after being squeezed by the push plate 6, the pressure block 9 moves to the outside of the first ring 4 and squeezes the square plate 11.
[0024] A fourth telescopic rod 32 is installed on the inner wall of the sampling rod 10. The other end of the fourth telescopic rod 32 is fixedly connected to the square plate 11, and the square plate 11 is located on the movement trajectory of the pressure block 9.
[0025] A second ring 25 is installed at the bottom of the support plate 1. A limit groove 26 is opened on the inner side of the second ring 25. A semi-circular rod 27 is installed on the outer side of the sampling rod 10.
[0026] The sampling rod 10 has a first square groove 28 on its side and a second square groove 33 on the inner side of the second ring 25. A fixing block 29 is slidably disposed on the inner side of the second square groove 33. A movable rod 30 is installed on the side of the fixing block 29. The movable rod 30 is movably connected to the second ring 25. A spring 31 is installed on the side of the fixing block 29 near the movable rod 30. The end of the spring 31 away from the fixing block 29 is fixedly connected to the inner wall of the second square groove 33. The detachable sampling rod 10 can store the soil in real time, and then the next sampling rod 10 can be replaced to continue sampling.
[0027] In this embodiment, when sampling is required, the drive device 3 can be activated, and the support plate 1 and sampling rod 10 can be rotated via the U-shaped plate 2, thereby inserting the sampling rod 10 into the soil. Then, the first threaded rod 7 is rotated, causing the push plate 6 to move downward. At this time, the first telescopic rod 5 is stretched, and when the push plate 6 moves downward, it squeezes the inclined surface of the pressure block 9 and causes the pressure block 9 to move outward of the first ring 4. At this time, the second telescopic rod 8 is contracted, and when the pressure block 9 moves, it squeezes the square plate 11 and causes the square plate 11 to move. At this time, the fourth telescopic rod 32 is contracted, and when the square plate 11 moves, it drives the collection box 15 to move to the outside of the opening slot 16 via multiple round rods 14 and inserts it into the soil for collection. In this way, multiple collection boxes 15 are used to simultaneously sample multiple layers of soil. After collection is completed, the first threaded rod 7 is reversed. At this time, the first telescopic rod 5 contracts, causing the push plate 6 to move upward and no longer squeeze the pressure block 9. The second telescopic rod 8, which is in the contracted state, resets, causing the pressure block 9 to reset. When the pressure block 9 stops pressing the square plate 11, the fourth telescopic rod 32, which is in a retracted state, drives the square plate 11 to reset. At the same time, the round rod 14 drives the collection box 15 to move to the inside of the opening slot 16. Meanwhile, the baffle 17 blocks the opening of the collection box 15 to seal and store the soil. Then, the sampling rod 10 is moved to the ground, and the movable rod 30 is pulled to move the fixed block 29 to the outside of the first square slot 28 and retract the fixed block 29 into the inside of the second square slot 33. At this time, the spring 31 retracts and releases the locking of the sampling rod 10 and the second ring 25. Then, the sampling rod 10 can be pulled to move the semi-circular rod 27 to the outside of the limiting slot 26. The sampling rod 10 is then removed to store the soil in real time. When it is necessary to take out the soil inside the collection box 15, the square plate 11 can be pushed to move the collection box 15 to the outside of the opening slot 16. Then, the storage box 18 inside the collection box 15 can be taken out to remove the soil. Then, the next sampling rod 10 is replaced to continue sampling.
[0028] Example 2 like Figures 1-10 As shown, based on Embodiment 1, a movable plate 20 is slidably arranged on the inner side of the sampling rod 10, and a spiral plate 19 is installed on the side of the movable plate 20.
[0029] A third telescopic rod 21 is installed on the inner wall of the sampling rod 10. A movable frame 22 is installed at the other end of the third telescopic rod 21. A connecting rod 23 is rotatably connected to the side of the movable frame 22. The connecting rod 23 is threadedly connected to the sampling rod 10. Multiple locking plates 24 are installed on the side of the movable frame 22. The locking plates 24 have an arc-shaped cross section and fit against the movable plate 20. The locking plates 24 are made of rubber. The locking plates 24 press the movable plate 20 to lock the position of the U-shaped plate 19 and the collection box 15.
[0030] The square plate 11 has multiple sliding grooves 12 on its side. A sliding block 13 is slidably disposed on the inner side of the sliding groove 12. The side of the sliding block 13 is fixedly connected to the round rod 14. The round rod 14 moves along the sliding groove 12 through the sliding block 13.
[0031] In this embodiment, when multiple layers need to be sampled simultaneously and the sampling depth of each layer needs to be changed, the connecting rod 23 can be rotated. The connecting rod 23 drives the movable frame 22 to move away from the herringbone plate 19, while the locking plate 24 stops pressing the movable plate 20. Then the herringbone plate 19 is slid, which drives the collection box 15 to move. When the collection box 15 moves, the round rod 14 moves along the sliding groove 12 through the sliding block 13. The positions of multiple collection boxes 15 are changed in sequence. Then the connecting rod 23 can be reversed to drive the movable frame 22 to move, while the multiple locking plates 24 press the movable plate 20 at the corresponding positions to lock the positions of the herringbone plate 19 and the collection box 15.
[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
