Description

Technical Field

[0001] The present invention relates to the technical field of soil detection equipment, and particularly relates to a rapid soil pH detection device for Chinese herbal medicine planting. Background Art

[0002] Implementing soil pH (pH value) detection during the planting of Chinese herbal medicines is a key measure to ensure the quality, yield, and safety of the medicines. Different Chinese herbal medicines have significant differences in their adaptability to soil pH. For example, Gardenia jasminoides, Magnolia officinalis, etc. are suitable for acidic environments with a pH value of 5.5 - 6.5. Ophiopogon japonicus and Lycium barbarum grow better in alkaline soils with a pH > 7.5. Most medicines such as Lilium brownii and Carthamus tinctorius are suitable for neutral to weak acid / weak base environments with a pH of 6.5 - 7.5. By detecting the pH value in the soil, growers can scientifically select land or adjust soil conditions to avoid poor growth or death caused by inappropriate acidity or alkalinity. The soil pH value directly affects the solubility and absorption efficiency of mineral elements. During the planting process of various Chinese herbal medicines, through acidity and alkalinity detection and scientific management, the yield, quality, and planting benefits of Chinese herbal medicines can be significantly improved, while reducing the environmental burden, meeting the development needs of sustainable agriculture.

[0003] Most of the existing soil acidity and alkalinity detection devices apply the method of using a pH meter. Before detection, the instrument needs to be calibrated with a standard buffer solution. Subsequently, the prepared soil solution is detected using the instrument, and the result is recorded after the reading stabilizes. This detection method is mostly applicable to laboratories. When performing soil acidity and alkalinity detection operations on the soil in the Chinese herbal medicine planting environment, soil sampling operations need to be carried out on the soil, and then the samples are transferred to the laboratory. After the samples are prepared, the detection operations are carried out. After the detection operations are completed, the acidity and alkalinity of the planting soil of Chinese herbal medicines are adjusted according to the detection results. The process is cumbersome and consumes human resources. If it is necessary to perform soil acidity and alkalinity detection operations on the planting soils of multiple types of Chinese herbal medicines, it will result in a long detection time and low efficiency. Therefore, the present invention provides a rapid soil pH detection device for Chinese herbal medicine planting. Summary of the Invention

[0004] In view of the above problems, the present invention provides a rapid soil pH detection device for Chinese herbal medicine planting.

[0005] To achieve the above object, the present invention provides the following technical solution: A rapid soil pH detection device for Chinese herbal medicine planting, including a first sampling frame, a second sampling frame, and a connecting support provided outside the two of them. A first lifting arm is provided at the end of the connecting support. A first electric gear is meshed and connected to the side of the first lifting arm through a vertically distributed rack. When the first electric gear rotates, the first lifting arm, the connecting support, the first sampling frame, and the second sampling frame can move up or down synchronously. When the first sampling frame and the second sampling frame descend, they can be embedded into the soil to perform sampling work.

[0006] Above the connecting support, there is a bracket. At the bottom end of the bracket, there are two positioning side frames. On the opposite sides of the two positioning side frames, there are rotatably installed extending arms that can rotate synchronously. One ends of the two extending arms away from the positioning side frames are connected by a sewage bucket. On one of the extending arms, there is a linkage gear disk that can rotate synchronously with it. The linkage gear disk meshes with the first electric gear. And the linkage gear disk and the first lifting arm are distributed on both sides of the first electric gear. When the first electric gear rotates and the first lifting arm and the connecting support rise synchronously, the linkage gear disk and the two extending arms rotate synchronously until the sewage bucket falls directly below the first sampling frame and the second sampling frame.

[0007] Further, at one end of the connecting support away from the first lifting arm, there is a second lifting arm. On the positioning side frames, there are vertically distributed first limiting sliders. The first limiting sliders are slidably connected to the second lifting arm. When the first electric gear meshes with the first lifting arm and the connecting support to move up or down synchronously, the second lifting arm moves along the distribution direction of the first limiting sliders.

[0008] Further, both the first sampling frame and the second sampling frame are composed of a semi-circular frame body and a semi-circular truncated cone-shaped frame body at its bottom end. When the first sampling frame and the second sampling frame are butted, the first sampling frame and the second sampling frame form a columnar accommodating space and an inverted truncated cone-shaped accommodating space distributed from top to bottom.

[0009] At the side edge of the first sampling frame, there is a sealing strip. When the first sampling frame and the second sampling frame are in a closed state, the sealing strip covers the side edge of the second sampling frame.

[0010] Further, at the end parts of the first sampling frame and the second sampling frame, there are a first guiding cross bar and a second guiding cross bar respectively. On one side of the connecting support facing the first guiding cross bar and the second guiding cross bar, there is a channel for accommodating the movement of the two.

[0011] The first guiding cross bar and the second guiding cross bar are distributed from top to bottom. And on the opposite sides of the first guiding cross bar and the second guiding cross bar, there are horizontally distributed racks. The two racks distributed from top to bottom are meshed and connected with the same third electric gear. The third electric gear is located in the relative space between the first guiding cross bar and the second guiding cross bar. And the third electric gear is installed outside the connecting support. When the third electric gear rotates, the first guiding cross bar and the second guiding cross bar can move in opposite directions until the first sampling frame and the second sampling frame move closer or move away from each other.

[0012] Further, a first linkage cross bar and a second linkage cross bar are respectively arranged at the ends of the first sampling frame and the second sampling frame away from the third electric gear. A channel for accommodating the movement of the two is opened on one side of the connection support opposite to the first linkage cross bar and the second linkage cross bar. Two horizontally distributed guide rails are fixed outside the connection support and are distributed from top to bottom. The first linkage cross bar and the second linkage cross bar are respectively slidably connected to the two horizontally distributed guide rails. When the first sampling frame and the second sampling frame move closer to or away from each other, the first linkage cross bar and the second linkage cross bar both move along the distribution direction of the horizontally distributed guide rails.

[0013] Further, two limiting sliders II perpendicular to the bracket are arranged on the bracket. A guiding arm is slidably connected to the limiting sliders II. The guiding arm has an inverted U-shaped structure, and a vertical rack is meshed and connected to the inner side of one of the legs of the guiding arm. The second electric gear is installed on the bracket. As the second electric gear rotates, the guiding arm moves up or down along the distribution direction of the limiting sliders II.

[0014] A probing frame is fixedly connected to the guiding arm. A water filtering plate is arranged at the bottom end of the probing frame. When the probing frame moves downwards along with the guiding arm and moves into the inner sides of the first sampling frame and the second sampling frame, the soil in the soil liquid is pressed below the water filtering plate, and the liquid in the soil liquid flows through the filter holes on the surface of the water filtering plate and moves above it.

[0015] Further, a detector is arranged on the probing frame. The detector is located above the water filtering plate. When the detector and the water filtering plate move into the inner sides of the first sampling frame and the second sampling frame, the detector contacts the liquid above the water filtering plate.

[0016] Further, two symmetrically distributed docking studs are arranged on the side surface of the sewage discharge bucket along its diameter direction. Removable threaded limit pins are arranged outside the extension arms. When the sewage discharge bucket is installed inside the relative space between the two extension arms, the threaded limit pins penetrate through the extension arms and are threadedly connected to the docking studs.

[0017] Further, one ends of the two positioning side frames close to the second lifting arm are connected by a support frame. A base is arranged at the bottom end of the support frame. A plurality of universal wheels are fixed to the bottom end of the base. When the first sampling frame and the second sampling frame move up and down, they can move through the inside of the base.

[0018] In summary, the technical effects and advantages of the present invention are as follows:

[0019] 1. The present invention is provided with a first sampling frame and a second sampling frame with adjustable heights. After the soil sampling operation is carried out, the soil can be located inside them for acid-base clothing detection operation. During the whole process, there is no need to transfer the soil additionally, which reduces the time required for the soil sample transportation operation, so as to achieve the purpose of rapid detection, facilitate the rapid detection operation of the soil in the outdoor environment, and improve the portability of the detection work.

[0020] 2. In the present invention, there is a sewage discharge bucket that can switch positions along with the lifting movement of the first sampling rack and the second sampling rack. Without affecting subsequent soil sampling and detection operations, the staff can separately transfer the soil samples in the sewage discharge bucket, facilitating the storage of soil samples and facilitating later review. After the transfer operation is completed, the empty sewage discharge bucket can be installed again to receive the soil samples that have completed subsequent detection. It is applicable to the detection operations of the soil pH values of multiple types of traditional Chinese medicinal materials, improving the efficiency of the detection operations.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0034] Example 1: Refer to Figures 1-3 A rapid soil acidity and alkalinity detection device for traditional Chinese medicine planting shown in the figure. During the process of soil acidity and alkalinity detection work, the entire device can be moved to the soil planting area. This device includes a first sampling rack 1, a second sampling rack 2, and a connecting support 3 provided outside the two. The end of the connecting support 3 is provided with a first lifting arm 31. The side of the first lifting arm 31 is meshed and connected with an electric gear one 4 through a vertically distributed rack. When the electric gear one 4 rotates, the first lifting arm 31 moves, and then the connecting support 3, the first sampling rack 1, and the second sampling rack 2 can be driven to move up or down synchronously.

[0035] When the electric gear one 4 rotates and drives the first lifting arm 31, the connecting support 3, the first sampling rack 1, and the second sampling rack 2 to move down synchronously, the first sampling rack 1 and the second sampling rack 2 are embedded into the soil to implement the sampling work. After the sampling work is completed, the electric gear one 4 rotates in the opposite direction, and the first lifting arm 31, the connecting support 3, the first sampling rack 1, and the second sampling rack 2 move up synchronously, so that the first sampling rack 1 and the second sampling rack 2 after sampling are separated from the soil, and the soil can be located inside the first sampling rack 1 and the second sampling rack 2 to receive the acid-base detection operation. There is no need to transfer the soil additionally during the whole process, which reduces the time required for the soil sample transfer operation, so as to achieve the purpose of rapid detection, facilitate the rapid detection operation of the soil in the outdoor environment, and improve the portability of the detection work.

[0036] As shown Figure 3 in the figure, a bracket 8 is provided above the connection support 3. Two positioning side frames 9 are provided at the bottom end of the bracket 8. Extending arms 6 that can rotate synchronously are rotatably installed on the opposite sides of the two positioning side frames 9. One ends of the two extending arms 6 away from the positioning side frames 9 are connected by a sewage bucket 7. A linkage gear disc 5 that can rotate synchronously with it is provided on one of the extending arms 6. The linkage gear disc 5 meshes with the first electric gear 4, and the linkage gear disc 5 and the first lifting arm 31 are distributed on both sides of the first electric gear 4 relatively.

[0037] Therefore, when the first electric gear 4 rotates, causing the first lifting arm 31 and the connection support 3 to rise synchronously, the linkage gear disc 5 and the two extending arms 6 will also rotate synchronously until the sewage bucket 7 falls directly below the first sampling frame 1 and the second sampling frame 2. After the pH detection of the soil samples inside the first sampling frame 1 and the second sampling frame 2 is completed, the sewage bucket 7 can receive the samples to facilitate the transfer operation of the waste soil samples.

[0038] Therefore, during the sampling and detection operations of the first sampling frame 1 and the second sampling frame 2, when the first electric gear 4 drives the first lifting arm 31 and the connection support 3 to descend and the first sampling frame 1 and the second sampling frame 2 perform sampling operations, the linkage gear disc 5 and the extending arms 6 can rotate synchronously and deviate from the first sampling frame 1 and the second sampling frame 2. When the first electric gear 4 drives the first lifting arm 31 and the connection support 3 to rise and the first sampling frame 1 and the second sampling frame 2 carry the soil samples up for pH detection operations, the linkage gear disc 5 and the extending arms 6 can rotate synchronously and be directly opposite to the first sampling frame 1 and the second sampling frame 2.

[0039] Furthermore, if the first sampling frame 1 and the second sampling frame 2 still need to perform soil pH detection operations at multiple positions within the traditional Chinese medicine planting area in the future, after the sewage bucket 7 receives the waste soil samples, the staff can detach the sewage bucket 7 and transfer the waste soil samples in the sewage bucket 7. During this process, the first sampling frame 1 and the second sampling frame 2 can continue to perform sampling operations at different positions within the traditional Chinese medicine planting area. At this time, since the extending arms 6 have deviated from the first sampling frame 1 and the second sampling frame 2, after transferring the waste soil samples in the sewage bucket 7, the empty sewage bucket 7 can be installed at the end of the extending arms 6 again. When the first sampling frame 1 and the second sampling frame 2 complete sampling and rise for soil pH detection operations, the empty sewage bucket 7 can fall below the first sampling frame 1 and the second sampling frame 2 again as the linkage gear disc 5 and the extending arms 6 rotate to receive the subsequent soil samples after detection. Throughout the process, it does not affect the smooth implementation of the sampling and detection work.

[0040] In the above process, while the sewage bucket 7 receives the waste soil samples, on the premise of not affecting the subsequent soil sampling and testing operations, the staff can also separately transfer the soil samples in the sewage bucket 7, which is convenient for soil sample storage and later review, applicable to the detection operations of the soil pH values of multiple types of Chinese medicinal materials, and improves the efficiency of the detection operations.

[0041] As Figure 4 shown, a second boom 32 is provided at one end of the connecting support 3 away from the first boom 31. Vertical limiting sliders 33 are provided on the positioning side frames 9. The limiting sliders 33 are slidably connected to the second boom 32. When the first electric gear 4 meshes with the first boom 31 and the connecting support 3 to move up or down synchronously, the second boom 32 moves along the distribution direction of the limiting sliders 33. The combined setting of the second boom 32 and the first boom 31 can maintain the stability of the connecting support 3 during the ascending and descending movements, and further maintain the stability of the first sampling frame 1 and the second sampling frame 2 during the moving process.

[0042] Embodiment 2: In the present invention, as Figures 5-8 shown, the first sampling frame 1 and the second sampling frame 2 are both composed of a semi-circular frame body and a semi-circular truncated cone-shaped frame body at its bottom end. When the first sampling frame 1 and the second sampling frame 2 are butted, the first sampling frame 1 and the second sampling frame 2 form a columnar accommodation space and a frustum of a cone-shaped accommodation space distributed from top to bottom. Soil samples are accommodated in this space. At the same time, the detection operation of the soil pH value can also be carried out in this space. To maintain the airtight state when the first sampling frame 1 and the second sampling frame 2 are spliced, a sealing strip 21 is provided at the side edge of the first sampling frame 1. When the first sampling frame 1 and the second sampling frame 2 are in a closed state, the sealing strip 21 covers the side edge of the second sampling frame 2. Refer to Figure 7 、 Figure 9 shown.

[0043] Specifically, a first guiding cross bar 16 and a second guiding cross bar 17 are respectively provided at the end parts of the first sampling frame 1 and the second sampling frame 2. A channel for the movement of the two is opened on one side of the connecting support 3 facing the first guiding cross bar 16 and the second guiding cross bar 17.

[0044] The first guiding cross bar 16 and the second guiding cross bar 17 are distributed from top to bottom, and transverse racks are provided on the opposite sides of the first guiding cross bar 16 and the second guiding cross bar 17. The two racks distributed from top to bottom are meshed with the same third electric gear 18. The third electric gear 18 is located in the relative space between the first guiding cross bar 16 and the second guiding cross bar 17, and the third electric gear 18 is installed outside the connecting support 3. When the third electric gear 18 rotates, the first guiding cross bar 16 and the second guiding cross bar 17 can move in opposite directions until the first sampling frame 1 and the second sampling frame 2 move closer or move away from each other.

[0045] During the sampling process of the first sampling frame 1 and the second sampling frame 2, before they are embedded in the ground, the electric gear three 18 rotates, and the first guiding cross bar 16 and the second guiding cross bar 17 respectively carry the first sampling frame 1 and the second sampling frame 2 to move away, leaving a space that can accommodate soil. After the first sampling frame 1 and the second sampling frame 2 are embedded in the ground, when it is ensured that there is soil inside them, the electric gear three 18 rotates in the reverse direction, and the first guiding cross bar 16 and the second guiding cross bar 17 respectively carry the first sampling frame 1 and the second sampling frame 2 to move closer until the first sampling frame 1 and the second sampling frame 2 are closely joined. At this time, with the rotation of the electric gear one 4, the connecting support 3 drives the first sampling frame 1 and the second sampling frame 2 in the closed state to rise, and the sampled soil smoothly detaches from the ground and undergoes a pH detection operation after rising.

[0046] When the soil undergoes a pH detection operation, the first sampling frame 1 and the second sampling frame 2 are still in a closed state. The staff can inject a liquid into it to mix with the soil to form a soil solution. After the soil solution stands for a certain period of time, a pH detection operation can be performed on it.

[0047] After the pH detection work is completed, the electric gear three 18 rotates, and the first guiding cross bar 16 and the second guiding cross bar 17 again carry the first sampling frame 1 and the second sampling frame 2 to move away. The soil inside it can smoothly fall into the sewage bucket 7 below it, facilitating the transfer operation of the waste soil sample.

[0048] In the above process, through the combined setting of the first sampling frame 1 and the second sampling frame 2, the present invention can switch the connection state between the two according to needs, adapt to different links in the sampling and detection work processes, and has the advantages of accurate and stable sampling during the soil sampling operation. During the detection operation, there is no need to replace the container additionally, improving the portability of the detection work.

[0049] As Figure 6 shown, one end of the first sampling frame 1 and the second sampling frame 2 far from the electric gear three 18 are respectively provided with a first linkage cross bar 19 and a second linkage cross bar 20. On one side of the connecting support 3 facing the first linkage cross bar 19 and the second linkage cross bar 20, a channel for the movement of the two is provided. Two horizontally distributed guide rails 34 are fixed outside the connecting support 3 from top to bottom. The first linkage cross bar 19 and the second linkage cross bar 20 are respectively slidably connected to the two horizontally distributed guide rails 34. When the first sampling frame 1 and the second sampling frame 2 move closer or farther away, the first linkage cross bar 19 and the second linkage cross bar 20 both move along the distribution direction of the horizontally distributed guide rails 34. The combined setting of the first linkage cross bar 19, the second linkage cross bar 20 and the horizontally distributed guide rails 34 improves the stability of the movement of the first sampling frame 1 and the second sampling frame 2, and further improves the tightness during their docking.

[0050] Embodiment 3: As Figure 10 shown, two limiting sliders II 10 vertically distributed with the bracket 8 are provided on the bracket 8. A guiding arm 11 is slidably connected to the limiting sliders II 10. The guiding arm 11 has an inverted U-shaped structure, and an electric gear II 12 is meshed and connected to the inner side of one of the legs of the guiding arm 11 through a vertically distributed rack. The electric gear II 12 is installed on the bracket 8.

[0051] After the soil liquid inside the first sampling rack 1 and the second sampling rack 2 in the closed state stands for a certain period of time, it can receive the pH detection operation. During the operation, as the electric gear II 12 rotates, the guiding arm 11 moves up or down along the distribution direction of the limiting sliders II 10. Since a probing rack 13 is fixedly connected to the guiding arm 11 and a water filtering plate 14 is provided at the bottom end of the probing rack 13. Therefore, when the guiding arm 11 descends, the probing rack 13 moves into the inner sides of the first sampling rack 1 and the second sampling rack 2 along with the descent of the guiding arm 11. The soil in the soil liquid is pressed below the water filtering plate 14, and the liquid in the soil liquid flows through the filter holes on the surface of the water filtering plate 14 to its upper side.

[0052] The setting of the water filtering plate 14 effectively filters out the clear liquid inside the soil liquid, so as to facilitate the subsequent pH detection operation. At the same time, the water filtering plate 14 can also compact the soil to avoid the fine soil blocks in the soil from polluting the monitoring equipment. When the pH detection operation of the soil is completed, due to the compaction of the soil, as the first sampling rack 1 and the second sampling rack 2 are separated, the soil can quickly fall into the sewage bucket 7.

[0053] As Figure 9 shown, a detector 15 is provided on the probing rack 13. The detector 15 is located above the water filtering plate 14. When the detector 15 and the water filtering plate 14 move into the inner sides of the first sampling rack 1 and the second sampling rack 2, the detector 15 contacts the liquid above the water filtering plate 14. The detector 15 in the present invention is a pH meter of the prior art and has been calibrated with standard buffer solutions (pH 4.0, 7.0, 9.2) before use. After the detector 15 is immersed in the supernatant inside the soil liquid, the result is recorded after the reading is stable.

[0054] As Figure 10 shown, two symmetrically distributed docking studs 71 are provided on the side of the sewage bucket 7 along its diameter direction. Removable threaded limit pins 61 are provided outside the extension arms 6. When the sewage bucket 7 is installed inside the relative space between the two extension arms 6, the threaded limit pins 61 penetrate through the extension arms 6 and are threadedly connected to the docking studs 71. Operating the threaded limit pins 61 can perform the disassembly and installation operations on the sewage bucket 7, so as to facilitate the transfer of the waste soil samples inside the sewage bucket 7 and at the same time facilitate the installation of the empty sewage bucket 7.

[0055] As Figure 1 、 Figure 2As shown, one end of two positioning side frames 9 close to the second lifting arm 32 is connected by a support frame 22. A base 23 is provided at the bottom end of the support frame 22, and a plurality of universal wheels 24 are fixed to the bottom end of the base 23. When the first sampling frame 1 and the second sampling frame 2 move up and down, they can move through the inside of the base 23. The combined setting of the support frame 22, the base 23 and the universal wheels 24 can facilitate the movement of the entire detection device in the present invention to a designated position and improve the operation portability.

[0056] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
