Description

Technical Field

[0001] This utility model relates to the field of agricultural disease sampling technology, specifically a sampling device for identifying agricultural diseases. Background Technology

[0002] In the field of agricultural disease identification and research, rapid, standardized, and contamination-free sampling of plant leaves is a crucial step in ensuring the accuracy of subsequent testing. Currently, most sampling methods involve manual cutting with blades or scissors. This method makes it difficult to guarantee the consistency of sample size and is highly susceptible to human contamination or sample damage, failing to meet the demands of modern agricultural research for standardized and high-throughput sampling.

[0003] To address the aforementioned issues, some specialized sampling devices have emerged on the market. For example, prior art (authorization announcement number: CN 221528043 U) discloses a scissor-type plant leaf perforation sampler, which achieves standardized perforation sampling by setting up fixed clamps, movable clamps, a punching block, and centrifuge tubes. It also solves the sealing problem of the sample storage container by using a sealing cap structure, thereby improving the standardization and anti-contamination capabilities of sampling to a certain extent.

[0004] However, this existing technology still has limitations: First, its operation logic is relatively complex. After sampling, it requires additional steps such as flipping the moving clamp, pushing the sealing cap, and pressing the stamping rod to complete the sealing and encapsulation of a single sample. This is inefficient, inconvenient, and not conducive to large-scale continuous operations in the field. Second, it has many structural components, which not only increases manufacturing costs but also makes cleaning and disinfection inconvenient and poses a risk of cross-contamination. Utility Model Content

[0005] This utility model addresses the aforementioned shortcomings of existing technologies by providing a sampling device for agricultural disease identification. The application adopts an intuitive linear operation mode of "grasp-cut-pull," which greatly reduces the labor intensity and training costs of operators, simplifies the operation process, and significantly improves operational efficiency and convenience. The simple structure and quick cleaning solve the problem of difficulty in thorough cleaning due to complex structure, avoids cross-contamination, and ensures the authenticity of samples and tests.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A sampling device for identifying agricultural diseases includes a base, with an adjustable pressure rod connected above the base. The end of the pressure rod is provided with a detachable cutting cylinder. One end of the base is connected with a rotatable support plate, and the upper end of the support plate is provided with a support block. The cutting cylinder and the support block cooperate to cut leaves for sampling. The sample is stored in the cutting cylinder, and a top block is provided inside the cutting cylinder to push the sample out.

[0007] Preferably, the upper end of the base is provided with a limiting hole, the bottom of the pressure rod is provided with a relief groove, a guide rod that cooperates with the limiting hole is connected in the relief groove, the lower end of the guide rod is connected with a limiting block, and a first spring connecting the pressure rod and the base is sleeved on the guide rod. Preferably, the upper end of the top block is connected to a through pressure rod and a slidingly fitted top rod. Preferably, the upper end of the top rod is provided with a pressure block, and a second spring is connected between the pressure block and the pressure rod. Preferably, the top block is cylindrical, and the sidewall of the top block is attached to the inner wall of the cutting cylinder.

[0008] Preferably, the end of the tray is connected to the base via a pivot.

[0009] Preferably, the lower end of the base is provided with a protrusion, and the upper end of the support plate is provided with a positioning groove that mates with the protrusion.

[0010] Preferably, the cutting cylinder and the pressure rod are threaded together.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model adopts an intuitive linear operation mode of "grasping-cutting-pushing". Compared with the complex operation of "pressing, flipping and pushing" in the prior art, the action is simpler and more continuous, which greatly reduces the labor intensity and training cost of operators. It is especially suitable for field environments that require frequent and rapid sampling. The operation process is simplified and the operation efficiency and convenience are significantly improved.

[0012] 2. The cutting cylinder of this utility model is detachable, which facilitates the disinfection and cleaning of the cutting cylinder, top block and tray. Moreover, the structure is simple and the cleaning is quick, which solves the problem of difficult thorough cleaning due to complex structure, avoids cross-contamination and ensures the authenticity of samples and tests.

[0013] 3. The entire process of the sample being cut off, temporarily stored in the cutting tube, and pushed into the container requires no human intervention or other tools (such as tweezers). This avoids human contamination of the sample, protects the operator from potential pathogens, and ensures the original state of the sample.

[0014] 4. Through the precise coordination of the cutting tube and the support block, circular samples with regular shapes and consistent diameters can be cut every time. This standardization is a prerequisite for accurate and repeatable disease identification and quantitative analysis, eliminating data bias caused by variations in sample size and improving the reliability of the test data. 5. The cooperation between the guide rod and the limiting hole ensures that the pressure rod maintains vertical movement without any wobbling during the pressing process, allowing the cutting cylinder and the support block to be precisely aligned for a clean and crisp cut. The cooperation between the protrusion and the positioning groove ensures the absolute accuracy of the support plate position during sampling, further ensuring the success rate of sampling and sample quality.

[0015] 6. The first spring automatically resets the pressure rod, and the second spring automatically resets the top block. After all actions are completed, the device automatically returns to the ready-to-operate state without manual intervention, ensuring smooth and consistent operation.

[0016] 7. Compared to the multiple precision injection molded parts and assembly steps required by the prior art, the structure of this application is simpler, with fewer parts, lower manufacturing costs, and greater robustness and durability. This reduces maintenance needs and long-term usage costs. The simple mechanical structure means fewer points of failure, higher reliability in long-term use, and is more suitable for use in relatively harsh field environments. It is also easy to operate, and any staff member can quickly get started, reducing the possibility of sample scrapping or equipment damage due to improper operation. Attached Figure Description

Detailed Implementation 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.

[0018] like Figure 1 , Figure 4As shown, a sampling device for agricultural disease identification includes a base 5, with an adjustable-space pressure rod 1 connected to the top of the base 5. A detachable cutting cylinder 3 is located at the end of the pressure rod 1. A rotatable support plate 4 is connected to one end of the base 5, and a support block 402 is located at the upper end of the support plate 4. The cutting cylinder 3 and the support block 402 work together to cut leaves for sampling. Through the precise cooperation between the cutting cylinder 3 and the support block 402, circular samples with regular shapes and consistent diameters can be cut each time. This is a prerequisite for accurate and repeatable disease identification and quantitative analysis, eliminating data deviations caused by inconsistent sample sizes. The sample is stored inside the cutting cylinder 3, which has a top block 203 that pushes the sample out. The cutting cylinder 3 and the top block 203 are made of corrosion-resistant and easily disinfected materials such as stainless steel. Their smooth surfaces and chemically stable properties prevent the residue of biological materials or chemical disinfectants, further ensuring the effectiveness and reliability of cleaning and disinfection.

[0019] For ease of cleaning, an external thread can be provided on the upper outer wall of the cutting cylinder 3, and a connecting hole with an internal thread can be provided at the bottom of the pressure rod 1. The cutting cylinder 3 and the pressure rod 1 are connected by a threaded fit. This allows the user to easily unscrew the cutting cylinder 3 for thorough 360° cleaning and disinfection (such as alcohol soaking or flame burning), perfectly solving the inherent problem of difficult thorough cleaning due to the complex structure and numerous gaps in the comparative documents.

[0020] In addition, a rubber anti-slip pad is added to the lower end of the base 5 to increase the friction for gripping. The upper end of the base 5 is provided with a limiting hole 503, and the bottom of the pressure rod 1 is provided with a relief groove 101. A guide rod 103 that mates with the limiting hole 503 is connected inside the relief groove 101, and a limiting block 104 is connected to the lower end of the guide rod 103. The cooperation between the guide rod 103 and the limiting hole 503 ensures that the pressure rod 1 always maintains vertical movement during the pressing process without any shaking, so that the cutting cylinder 3 and the support block 402 can be accurately aligned and cut cleanly.

[0021] The guide rod 103 is fitted with a first spring 102 that connects the pressure rod 1 and the base 5. When sampling is performed by gripping the pressure rod 1 and the base 5, the first spring 102 can push the pressure rod 1 and the base 5 apart after releasing the grip, thus achieving a reset. The device automatically returns to the ready-to-operate state without manual intervention, ensuring smooth and consistent operation.

[0022] The top block 203 is connected to a push rod 2 that passes through the pressure rod 1 and is slidably engaged. The push rod 2 pushes the top block 203, which can push the sample out of the cutting tube 3. The upper end of the top rod 2 is provided with a pressure block 201. A second spring 202 is connected between the pressure block 201 and the pressure rod 1. The second spring 202 can drive the top block 203 to reset. The top block 203 is cylindrical, and its sidewalls are attached to the inner wall of the cutting tube 3. After the sample is cut, it is gently pushed into the cutting tube 3 by the support block 402 for temporary storage, preventing it from falling off or being lost. When pushed out, the cylindrical top block 203, which is in close contact with the inner wall of the cutting tube 3, pushes it out smoothly and completely, effectively preventing the crushing damage that the punch rod 1 in the comparative document may cause to the sample, especially for tender or rotten diseased leaf tissue.

[0023] like Figure 2 As shown, the end of the tray 4 is connected to the base 5 via a pivot 502, and the lower end of the base 5 is provided with a protrusion 501, as shown. Figure 3 As shown, the upper end of the tray 4 is provided with a positioning groove 401 that cooperates with the protrusion 501. After the protrusion 501 is aligned with the upper and lower positions of the cutting cylinder 3, the protrusion 501 and the positioning groove 401 cooperate perfectly, thereby realizing the positioning of the tray 4 and ensuring the absolute accuracy of the position of the tray 4 during sampling, further ensuring the success rate of sampling and sample quality.

[0024] In use, place the blade between the cutting cylinder 3 and the support block 402, grasp the pressure rod 1 and the base 5 by hand, and the cutting cylinder 3 and the support block 402 work together to cut the circular sample. The sample is pushed into the cutting cylinder 3 by the support block 402. Since the sample is relatively light, it will not fall out of the cutting cylinder 3 automatically. Rotate the support plate 4 to make room below the cutting cylinder 3, place the sample storage container below the cutting cylinder 3, push the push rod 2, and push the sample out through the push block 203.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
