Description

Technical Field

[0001] This utility model relates to the field of farmland measurement technology, and in particular to a farmland soil wind erosion measurement device. Background Technology

[0002] Soil erosion is a major soil degradation process occurring in arid, semi-arid, and some semi-humid regions, especially in areas with high fertility soils such as black soil regions. It leads to the loss of large amounts of nutrient-rich, fine-grained topsoil, directly reducing soil fertility and arable land productivity, and posing a serious threat to the regional ecological environment and air quality. Therefore, accurate and efficient measurement of soil erosion is a crucial foundation for soil erosion prevention and control, assessing the degree of land degradation, and developing scientific farming strategies.

[0003] A search revealed that patent CN223180028U discloses a soil wind erosion measuring device for farmland. By activating the electric push rod at the top of the adjustment frame, the sliding plate on the outer surface of the slide bar squeezes the support spring and moves vertically downward along the ventilation opening, thereby driving several sets of sand collection boxes to move downward synchronously to a designated height so that workers can collect the sand and dust inside.

[0004] However, the aforementioned device has the following drawbacks: First, all sand collection boxes at the same height face the same direction, making it difficult to effectively capture wind-eroded materials from different directions, resulting in sampling results that are not representative of actual measurements. Simultaneously, the flat bottom of the collection boxes lacks an effective mechanism for retaining collected samples. Under continuous wind disturbance, settled sand, especially fine particles, can easily be blown out or stirred up again, causing systematic bias in the measurement results and failing to accurately reflect the true wind erosion flux. Second, devices using electric actuators or other power components for height adjustment or retraction require an external power supply or a large-capacity battery. This significantly increases the difficulty of deployment and operating costs in remote farmland environments lacking stable power supply, and the power lines also pose inconvenience and safety hazards for long-term field monitoring. Third, the fixing components contain many independent parts, requiring precise alignment and multi-step tightening operations during installation. Operation in soft or uneven farmland soil is time-consuming and laborious, and disassembly and relocation are equally inconvenient. Therefore, further improvements are needed. To this end, we propose a farmland soil wind erosion measurement device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for measuring soil wind erosion in farmland.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a farmland soil wind erosion measuring device, comprising a pole, wherein a plurality of first sliding sleeves are slidably sleeved on the surface of the pole, a plurality of side rods are fixed on the outer side wall of each first sliding sleeve, and a collecting component is fixedly connected to the other end of each side rod, and a base plate is fixed on the bottom surface of the pole, wherein a foldable and unfoldable support component is connected together with the surface of the pole on the upper surface of the base plate.

[0007] Furthermore, the collection assembly includes a collection box fixedly connected to a side rod, the end of the collection box away from the side rod being open, a conical hopper being fixed through the bottom wall of the collection box, a detachable collection bottle being fixed to the lower surface of the collection box, and the bottom end of the conical hopper being located inside the collection bottle.

[0008] Furthermore, an annular plate is fixed to the lower surface of the collection box and outside the cone. The outer surface of the annular plate is provided with external threads, and the inner sidewall of the top of the collection bottle is provided with internal threads. The collection bottle is rotatably connected to the surface of the annular plate through the threads.

[0009] Furthermore, the first sliding sleeve sidewall is connected to a first locking bolt through a threaded connection, and the surface of the upright is provided with scale lines.

[0010] Furthermore, the bottom end of the pole has a pointed design.

[0011] Furthermore, the support assembly includes a second sliding sleeve that is slidably fitted onto the bottom surface of the upright. Multiple support rods are hinged to the outer wall of the second sliding sleeve. Each support rod has a pad hinged to its other end. A through hole is provided in the center of the pad, and a ground nail passes through the through hole.

[0012] Furthermore, the second sliding sleeve sidewall is connected to a second locking bolt via a threaded connection, and the support assembly also includes multiple connecting rings fixed to the upper surface of the base plate, each of which is rotatably connected to a hook, and the middle of each support rod is fixed with a hanging ring for connecting the hook.

[0013] The beneficial effects of this utility model are: 1. This utility model effectively solves the problems of insufficient sampling representativeness and easy sample loss through optimized structural design. Each first sliding sleeve's outer wall is connected to an independent collection component via a side rod, enabling comprehensive collection of sand from all directions at the same height, significantly improving the spatial representativeness of the sampling and the accuracy of wind erosion flux data. Furthermore, the bottom of the collection box uses a conical structure to transition to the collection bottle, allowing sand to quickly slide into the lower collection bottle for storage. This effectively isolates the captured sand from the external wind field, fundamentally preventing sample re-blowing or dust loss due to continuous wind disturbance, ensuring the reliability and accuracy of the measurement results.

[0014] 2. This utility model eliminates the reliance on external power for adjustment found in existing technologies. During operation, simply loosening or tightening the first locking bolt allows the first sliding sleeve to move freely up and down along the surface of the pole, and precise positioning is achieved through the scale lines on the pole surface. The entire process requires no external power supply, greatly improving the deployment flexibility and ease of use of the device in field environments without electricity. Simultaneously, the device is equipped with a foldable support assembly, which can be unfolded during operation to provide stable support for the pole, ensuring overall stability in strong winds; after use, it can be easily folded back to the side of the pole, significantly reducing the device's storage volume and footprint, facilitating transportation and storage, and better meeting the actual operational needs of farmland monitoring.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-4As shown, a soil wind erosion measuring device for farmland is disclosed, comprising a pole 1, a plurality of first sliding sleeves 2 slidably sleeved on the surface of the pole 1, a plurality of side rods 3 fixed on the outer side wall of each first sliding sleeve 2, a collection component 4 fixedly connected to the other end of each side rod 3, a base plate 6 fixed on the bottom surface of the pole 1, and a foldable and unfoldable support component 7 connected together with the surface of the pole 1 on the upper surface of the base plate 6.

[0020] The collection assembly 4 includes a collection box 41 fixedly connected to the side rod 3. The end of the collection box 41 away from the side rod 3 is open. A cone 42 is fixed through the bottom wall of the collection box 41. A detachable collection bottle 44 is fixed to the lower surface of the collection box 41, and the bottom end of the cone 42 is located inside the collection bottle 44.

[0021] The collection box 41 at the same height can collect sand and dust from different directions. When the sand and dust enter the collection box 41, it will fall into the cone 42 and then slide into the collection bottle 44 along the cone 42. The sand and dust that enters the collection bottle 44 is not easily blown out by the wind.

[0022] An annular plate 43 is fixed on the lower surface of the collection box 41 and outside the cone 42. The outer surface of the annular plate 43 is provided with external threads, and the inner side wall of the top of the collection bottle 44 is provided with internal threads. The collection bottle 44 is rotatably connected to the surface of the annular plate 43 through the threads.

[0023] Therefore, when collecting the sand and dust, the collection bottle 44 can be unscrewed from the surface of the annular plate 43 to pour out the sand and dust in the collection bottle 44.

[0024] The first sliding sleeve 2 has a through-wall connection to a first locking bolt 21 via a threaded connection, and the surface of the upright 1 is marked with scale lines 5. When adjusting the height of each layer of collecting components 4, first loosen the first locking bolt 21 to release its pressure on the surface of the upright 1. Then, slide the first sliding sleeve 2 upwards or downwards, confirming the height according to the scale lines 5. After adjustment, tighten the first locking bolt 21 to press the upright 1 again, thus fixing the height of the first sliding sleeve 2 and the multiple collecting components 4 in that layer. Furthermore, the thread helix angle between the first locking bolt 21 and the first sliding sleeve 2 should be less than the equivalent friction angle to ensure self-locking, and the material selection can ensure that the pressing force is sufficient to support the weight of the multiple collecting components 4.

[0025] The bottom of pole 1 is designed with a pointed tip, making it easy to insert the bottom of pole 1 into the farmland.

[0026] The support assembly 7 includes a second sliding sleeve 71 that is slidably sleeved on the bottom surface of the upright 1. Multiple support rods 72 are hinged to the outer wall of the second sliding sleeve 71. Each support rod 72 has a pad 73 hinged to its other end. A through hole is provided in the middle of the pad 73, and a ground nail 74 passes through the through hole.

[0027] In use, the second sliding sleeve 71 can be slid down to open the support rod 72 away from the upright 1. Then, the ground nail 74 passing through the hole is driven into the ground to fix the pad 73, thereby using the support rod 72 to support the upright 1.

[0028] The second sliding sleeve 71 has a second locking bolt 78 that is threaded through its side wall and rotatedly connected to it. The support assembly 7 also includes multiple connecting rings 75 fixed to the upper surface of the base plate 6. Each connecting ring 75 is rotatably connected to a hook 76. The middle of each support rod 72 is fixed with a hanging ring 77 for connecting the hook 76.

[0029] After sliding the second sliding sleeve 71 downwards to unfold the support rod 72, before fixing the ground nail 74, first hang each hook 76 on the hanging ring 77 in the middle of the corresponding support rod 72, thereby fixing the support rod 72, and finally fixing the ground nail 74.

[0030] Working principle: During installation, insert the bottom end of the upright pole 1 into the farmland until the base plate 6 contacts the ground. Then, slide the second sliding sleeve 71 downwards to open the multiple support rods 72 away from the upright pole 1. Hang each hook 76 on the hanging ring 77 in the middle of the corresponding support rod 72 to fix the angle of the support rod 72. Then, drive the ground nail 74 through the hole in the pad 73 into the ground to fix the pad 73. Finally, tighten the second locking bolt 78 to press the upright pole 1 to lock the position of the second sliding sleeve 71, thereby forming a stable support for the upright pole 1 through the support assembly 7. When it is necessary to adjust the collection height, first loosen the first locking bolt 21 to release its pressure on the upright pole 1. Then, slide the first sliding sleeve 2 up and down along the surface of the upright pole 1. After determining the target height by referring to the scale line 5, tighten the first locking bolt 21 again to press the upright pole 1, which can fix the position of all collection assemblies 4 in this layer. The whole process does not require electric drive.

[0031] During collection, the sand enters through the opening of the collection box 41, falls into the cone hopper 42, and slides along its slope into the collection bottle 44 for storage, effectively preventing it from being blown out by the wind; when it is necessary to take out the sample, the collection bottle 44 can be directly unscrewed from the surface of the annular plate 43 to pour out the sand.

[0032] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
