Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plant sampling, in particular to a sampling device for plant disease identification. Background Art
[0002] Plant diseases are caused by various pathogens, including bacteria, fungi, viruses, nematodes, and other microorganisms. These pathogens can be transmitted through air, soil, water, insects, etc. Plant diseases usually show lesions in local or specific areas, while the whole plant may not be completely affected. Therefore, using a sampling device can ensure obtaining representative samples from the affected areas for accurate disease identification and analysis.
[0003] Traditional sampling devices usually consist of a base, a sampling knife, a spring, a pressing plate, and a sampling container. The operator places the plant leaf or sample on the sampling device. The operator operates the handle or rod to store and release energy in the spring device, thereby pressing the sampling knife onto the plant leaf or sample to quickly cut and remove the sample. After cutting, the sampling knife will bring the sample to a collection area, usually a container or carrier, for subsequent observation and analysis. As needed, the operator can repeat the above operation to sample plant tissues at multiple positions to obtain more comprehensive sample data.
[0004] However, traditional sampling devices cannot replace the appropriate sampling knife according to actual needs. Different plant parts or diseases require different types of sampling knives to ensure accurate and effective sampling. The inability to replace the sampling knife will result in incomplete, inaccurate sampling or damage to the sample, thereby affecting the accuracy and reliability of disease identification. Summary of the Utility Model

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a sampling device for identifying plant diseases, comprising a bottom plate 1, a hollow box 12 is arranged on the top of the bottom plate 1, a sliding block 14 is slidably connected inside the hollow box 12, a sliding block 2 15 is slidably connected inside the hollow box 12, one end of a spring 2 16 is fixedly connected to the side wall of the sliding block 14, the other end of the spring 2 16 is fixedly connected to the side wall of the sliding block 2 15, a clamping block 17 is fixedly connected to the lower surface of the sliding block 14, a clamping block 2 18 is fixedly connected to the lower surface of the sliding block 2 15, a fixed block 19 is arranged at the bottom of the hollow box 12, the clamping block 17 and the clamping block 2 18 are both slidably connected to the inner wall of the fixed block 19, a leaf sampling knife 20 is fixedly connected to the lower surface of the fixed block 19, and a supporting assembly is arranged on the upper surface of the bottom plate 1;
[0034] Specifically, pressing the sliding block 14 and the sliding block 2 15 at the same time will cause the two sliding blocks to slide inside the hollow box 12. This sliding not only realizes the relative movement of the sliding block 14 and the sliding block 2 15 inside each other, but also squeezes the spring 2 16 on both sides to shrink. Then, with the movement of the sliding block 14 and the sliding block 2 15, the clamping block 17 and the clamping block 2 18 will slide out from the inside of the fixed block 19. This step is very critical because it releases the fixing effect of the clamping block on the fixed block 19, making the fixed block 19 movable. Remove the leaf sampling knife 20, and then select a suitable leaf sampling knife 20 according to the sampling requirements. Selecting a suitable leaf sampling knife 20 is crucial to improving the efficiency of the sampling process. Different leaf sizes and plant types require different sampling knives to ensure the accuracy and efficiency of sampling. By using a suitable sampling knife, the staff can reduce unnecessary waste of time and improve efficiency.
[0035] Reference Figure 1 and Figure 4, the support assembly includes a support column 7, the support column 7 is fixedly connected to the upper surface of the bottom plate 1, a support block 8 is fixedly connected to the outer wall of the support column 7, a handle 21 is fixedly connected to the side wall of the support block 8, a pressing plate 10 is slidably connected inside the support block 8, a sliding column 11 is fixedly connected to the inner wall of the pressing plate 10, a hollow box 12 is fixedly connected to one end of the sliding column 11, the sliding column 11 is slidably connected inside the support block 8, the pressing plate 10 is slidably connected inside the support block 8, a first spring 9 is arranged on the outer wall of the sliding column 11, one end of the first spring 9 is fixedly connected to the bottom wall inside the support block 8, and the other end of the first spring 9 is fixedly connected to the lower surface of the pressing plate 10. A sampling bottle 13 is slidably connected inside the bottom plate 1, and a threaded plate 2 is fixedly connected to the upper surface of the bottom plate 1;
[0036] Specifically, by pressing the sliding column 11, the pressing plate 10 is driven to move downward inside the support block 8. During this process, the downward movement of the pressing plate 10 compresses the first spring 9, causing it to contract. At the same time, the downward movement of the sliding column 11 drives the blade sampling knife 20 to descend synchronously. When everything is ready, the blade sampling knife 20 can start cutting and sampling the blade. The cut blade will directly fall into the sampling bottle 13, which is beneficial to maintaining the integrity of the blade and ensuring the sample quality. After completing the cutting and sampling on one side, the first spring 9 will automatically rebound to prepare for the next cutting and sampling. When the sampling bottle 13 is filled with leaf samples, we need to remove it. At this time, simply push the sampling bottle 13 upward from bottom to top, so that it slides inside the bottom plate 1. At the same time, the columns on both sides of the sampling bottle 13 will also slide and move out of the bottom plate 1. These two columns ensure the stability of the sampling bottle 13 during the sampling process and prevent possible shaking during the operation.
[0037] Refer to Figure 1 and Figure 5 , a support shaft 3 is fixedly connected inside the threaded plate 2, a sliding plate 4 is slidably connected to the outer wall of the support shaft 3, a threaded column 5 is threadedly connected inside the threaded plate 2, the sliding plate 4 is slidably connected to the upper surface of the bottom plate 1, the threaded column 5 is rotatably connected inside the sliding plate 4, and a rotating plate 6 is fixedly connected to one end of the threaded column 5;
[0038] Specifically, place the plant leaf on the upper surface of the sampling bottle 13. This step is to ensure the accuracy and integrity of the leaf sample. Next, rotate the component rotating plate 6 on the right side. This is one of the core operations. The rotation of the rotating plate 6 will drive the threaded column 5 to perform threaded rotation inside the threaded plate 2. It should be noted that the threaded plate 2 is fixed on the surface of the bottom plate 1, so it will not rotate with the rotation of the threaded column 5. The threaded column 5 will push the sliding plate 4 to slide outside the support shaft 3. When the sliding plate 4 moves to a position where it is in close contact with the leaf edge, stop rotating the rotating plate 6. In this way, the preliminary positioning is completed. Next, we need to perform further positioning adjustment by moving the sliding plate 4 on the left side. This step is crucial because it can ensure that during sampling, the sampling device can accurately position and collect a complete leaf sample.
[0039] Working principle: When it is necessary to replace the blade sampling knife 20 according to the size of the blade sample or different types of plants, first press the slider one 14 and the slider two 15 simultaneously. This will cause the slider one 14 and the slider two 15 to slide inside the hollow box 12. At the same time, the slider one 14 and the slider two 15 will also slide inside each other, which will simultaneously squeeze the two springs two 16 on both sides to make them contract. At the same time, the slider one 14 will drive the clamping block one 17 to slide out of the fixed block 19, and the slider two 15 will also drive the clamping block two 18 to slide out of the fixed block 19. In this way, the clamping block one 17 and the clamping block two 18 will no longer restrict the position of the fixed block 19. At this time, the original blade sampling knife 20 can be removed, and then the blade sampling knife 20 can be replaced according to different requirements. Selecting the appropriate blade sampling knife 20 according to actual needs can improve the efficiency of the sampling process and reduce unnecessary time waste. When it is necessary to position the plant leaf, first place it on the upper surface of the sampling bottle 13 according to the position where the plant leaf needs to be sampled. Then, rotate the rotating plate 6 on the right side. The rotation of the rotating plate 6 will cause the threaded column 5 to rotate internally on the threaded plate 2. Since the threaded plate 2 is fixed on the surface of the bottom plate 1, the threaded plate 2 will not follow the rotation of the threaded column 5 but move on its internal thread. This movement will push the sliding plate 4 to slide outside the support shaft 3. When the sliding plate 4 moves to a position where it is closely attached to the leaf edge, stop rotating the rotating plate 6 to complete the preliminary positioning. Then, move the sliding plate 4 on the left side to further position and adjust the leaf to ensure that it is completely attached to the device. This process ensures that during sampling, the sampling device can accurately position and collect samples. When it is necessary to sample after the leaf positioning is completed, first press the sliding column 11 to drive the pressing plate 10 to slide downward inside the support block 8. The descent of the pressing plate 10 will squeeze the spring one 9 to make it contract, and the descent of the sliding column 11 will drive the blade sampling knife 20 to descend. Then, the blade sampling knife 20 will cut and sample the leaf, and the cut leaf will directly fall into the sampling bottle 13. After the leaf is cut, the spring one 9 will rebound to facilitate the next side of the cutting and sampling. When it is necessary to remove the sampling bottle 13 after it has collected the leaf, directly push the sampling bottle 13 from bottom to top. This will cause the sampling bottle 13 to slide inside the bottom plate 1, and at the same time, the columns on both sides of the sampling bottle 13 will also slide and move out of the bottom plate 1. These two columns on both sides can ensure the stability of the sampling bottle 13 during sampling. The sampling device can be easily carried through the handle 21.
