Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil sampling technology, and in particular to a rapid soil sampling device for Chuzhou chrysanthemum. Background Technology
[0002] Chrysanthemum chuzhouensis, a plant with significant economic and medicinal value, is highly dependent on soil conditions during its cultivation. Soil nutrient content, pH value, humidity, and other parameters directly affect the growth quality and yield of chrysanthemum chuzhouensis. Therefore, obtaining and analyzing soil samples quickly and accurately is of great significance for optimizing the cultivation and management of chrysanthemum chuzhouensis. However, traditional manual sampling methods, such as shovel digging and manual separation of rhizosphere soil, have problems such as high risk of sample contamination, difficulty in stratified collection, and serious damage to microbial activity, which cannot meet the refined needs of chrysanthemum chuzhouensis rhizosphere microecology research.
[0003] Existing soil sampling devices mostly operate manually or semi-automatically. Their core structure typically includes a sampling tube, a handle, and a sample collector. The sampling tube is usually a fixed-length metal tube with a sharp blade at the front end for easy insertion into the soil. The handle is usually a simple grip structure, and the sampling tube is pushed into the soil manually. The sample collector is used to remove the soil sample from the sampling tube by rotating or pulling. Some high-end devices are equipped with simple depth markers, but the adjustment range is limited and they rely on manual operation. In addition, the sampling heads of existing devices are mostly fixed and cannot be changed according to different soil types, resulting in low sampling efficiency in hard soils or clay.
[0004] However, existing technologies have a significant problem: due to the fixed length of the sampling tube, the device is difficult to adapt to sampling needs at different depths in practical use. For example, when analyzing the root distribution of Chuzhou chrysanthemum, the sampling depth needs to be adjusted according to the root growth depth, but the fixed-length sampling tube cannot meet this requirement. In addition, in soil profile analysis, the soil characteristics at different depths will have significant differences, and the fixed-length sampling tube is difficult to accurately obtain samples at the target depth. This problem seriously limits the applicability of soil sampling devices and the accuracy of data analysis, making it difficult to meet the needs of precision agriculture in Chuzhou chrysanthemum cultivation. To address these issues, a rapid soil sampling device for Chuzhou chrysanthemum is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a rapid soil sampling device for Chuzhou chrysanthemum, which aims to improve the problems of fixed soil sampling depth, lack of stratified collection capability, and inability to flexibly adjust sampling depth in the existing technology.

[0023] This utility model has the following beneficial effects:
[0024] 1.

Detailed Implementation
[0032] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a rapid soil sampling device for chrysanthemum, comprising a sampling tube 1 and a sampling head 3. The sampling head 3 is used to insert into the soil to collect soil samples. An extension rod 2 is slidably connected inside the sampling tube 1. The extension rod 2 is used to facilitate the user to adjust the length of the device at any time, thereby improving the flexibility and convenience of the device. A limit frame 4 is fixedly connected to the outer wall of the sampling tube 1 to stabilize the device and prevent displacement of the device during the sampling process. An adjustment component is provided at the top of the sampling tube 1 to facilitate the user to adjust the height of the device at any time.
[0034] The adjustment assembly includes a connecting frame 5, which provides stable support and connection for the adjustment assembly, ensuring the stability of its movement. The bottom of the connecting frame 5 is fixedly connected to the top of the sampling tube 1. Symmetrical support blocks 7 are fixedly connected to the side wall of the connecting frame 5. Multiple limiting grooves 6 are opened inside the extension rod 2, which are used to cooperate with the locking column 9 to achieve the locking function of the adjustment assembly. A rotating shaft 11 is rotatably connected inside the support block 7. A pressing plate 8 is fixedly connected to the outer wall of the rotating shaft 11 to transmit power, ensuring that the operator can quickly drive the movement of the assembly. A locking column 9 is fixedly connected to one side of the pressing plate 8. The locking column 9 fits into the limiting groove 6. Through the cooperation of the locking column 9 and the limiting groove 6, the adjustment assembly can be locked and unlocked. Elastic pads 10 are provided on one side of the pressing plate 8 to provide elastic restoring force for the assembly, ensuring that the assembly can recover. One end of each elastic pad 10 is fixedly connected to the side wall of the pressing plate 8, and the other end is fixedly connected to the outer wall of the sampling tube 1. A replacement assembly is provided on the top of the sampling head 3, which is used to facilitate the user to replace different sampling heads 3.
[0035] Specifically, when the sampling depth needs to be flexibly adjusted according to the root distribution of Chrysanthemum morifolium, soil profile characteristics, or research objectives, the operator accurately aligns the sampling head 3 with the soil surface to be sampled and uses the limiting frame 4 to ensure the precise position of the sampling head 3, thereby avoiding deviation during sampling. When the sampling head 3 is inserted into the soil for sampling, if the height of the device needs to be adjusted according to the actual use, the operator only needs to press the pressing plate 8. Under the action of the pressing force, the pressing plate 8 drives the rotating shaft 11 to rotate inside the support block 7, causing the pressing plate 8 to deflect. This movement further drives the locking column 9 to disengage from the limiting groove 6, thereby unlocking it. This allows the extension rod 2 to be pulled and slid inside the sampling tube 1, quickly adjusting the length of the device. At the same time, the movement of the pressing plate 8 also compresses the elastic pad 10, causing it to elastically deform. After adjusting to the appropriate length, the elastic pad 10 pushes the pressing plate 8 back to its original position through the restoring force, causing the locking column 9 to re-lock into the limiting groove 6, thereby locking the device, ensuring the stability of the sampling equipment, and ensuring that there is no loosening or deviation during the sampling process.
[0036] Reference Figure 3 and Figure 4 The replacement component includes a connecting plate 12 and a fixing plate 13. The top of the connecting plate 12 is fixedly connected to the bottom of the sampling tube 1, providing a stable connection and support for the replacement component. The fixing plate 13 is slidably connected inside the connecting plate 12, and its bottom is fixedly connected to the top of the sampling head 3. The fixing plate 13 has symmetrical slots 14 inside, which, through cooperation with other components, allow for quick unlocking and locking of the replacement component, facilitating adjustments by the operator. Symmetrical fixing shafts 15 are fixedly connected to the outer wall of the connecting plate 12. A sliding shaft 16 is slidably connected inside the fixing shafts 15, and a pull column 17 is fixedly connected to one end of the sliding shaft 16 to transmit the operator's force and ensure rapid response of the component. A compression plate is fixedly connected to the inner wall of the fixing shaft 15. 19 is used to provide extrusion force to ensure the stable deformation of spring 20. The other end of the sliding shaft 16 is fixedly connected to a locking post 21, which engages with the slot 14. Through the cooperation of the locking post 21 and the slot 14, the component replacement can be quickly unlocked and locked, ensuring quick replacement and stability after replacement. The outer wall of the sliding shaft 16 is fixedly connected to a compression disc 18, which is used to further transmit power so that spring 20 can be compressed and deformed. The compression disc 18 slides inside the fixed shaft 15. The outer wall of the sliding shaft 16 is provided with a spring 20, which is used to provide necessary elastic support for the component and provide elastic restoring force to ensure the stable movement of the component. One end of the spring 20 is fixedly connected to the side wall of the compression disc 19, and the other end is fixedly connected to the side wall of the compression disc 18.
[0037] Specifically, when encountering different soil types or needing to expand sampling capabilities, operators can pull the pull column 17 to cause the sliding shaft 16 to slide inside the fixed shaft 15. The sliding of the sliding shaft 16 causes the engaging column 21 to disengage from the slot 14, thus unlocking the device and allowing the sampling head 3 to be replaced. During the sliding of the sliding shaft 16, the first extrusion plate 18 and the second extrusion plate 19 cooperate to slide synchronously on the inner wall of the fixed shaft 15 and jointly compress the spring 20, causing it to undergo elastic deformation and store elastic potential energy. The restoring force of the spring 20 pushes the engaging column 21 back into the slot 14, locking the sampling head 3. This allows operators to easily and quickly replace the sampling head 3 and ensures its secure locking, effectively improving the flexibility and efficiency of the equipment.
[0038] Working Principle: When using this soil sampling device, the operator aligns the sampling head 3 with the soil surface to be sampled. The limiting frame 4 ensures the accuracy of the sampling head 3's position and prevents deviation during sampling. Soil is collected by inserting the sampling head 3 into the soil. When the height of the device needs to be adjusted according to actual use, the operator presses the pressing plate 8. Under the pressure, the pressing plate 8 drives the rotating shaft 11 to rotate inside the support block 7, causing the pressing plate 8 to deflect. This movement of the pressing plate 8 drives the locking column 9 to disengage from the limiting groove 6, unlocking the device. After unlocking, the extension rod 2 is pulled, allowing it to slide inside the sampling tube 1, thus quickly adjusting the device length. Simultaneously, the movement of the pressing plate 8 compresses the elastic pad 10, causing it to deform elastically. After adjusting to the appropriate length, the elastic pad 10... The elastic restoring force pushes the pressing plate 8 to reset, thereby causing the locking column 9 to re-engage into the limiting groove 6 for locking, thus ensuring the stability of the component. When the sampling head 3 needs to be replaced according to different soil conditions, the operator pulls the pull column 17, and the sliding shaft 16 slides inside the fixed shaft 15 under the action of the pulling force. The sliding shaft 16 drives the locking column 21 to disengage from the slot 14 to unlock, thus making it convenient for the operator to adjust the sampling head 3 at any time. At the same time as the sliding shaft 16 slides, it also drives the first extrusion plate 18 to slide synchronously on the inner wall of the fixed shaft 15, thereby cooperating with the second extrusion plate 19 to compress the spring 20, causing the spring 20 to undergo elastic deformation and store elastic potential energy. The elastic restoring force of the spring 20 pushes the locking column 21 to re-engage into the slot 14, thereby achieving the locking of the sampling head 3, which facilitates the operator to replace and maintain the sampling head 3 at any time.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
