Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, and in particular to a tomato leaf cutting and sampling device. Background Technology

[0002] Tomato leaf sampling is an important tool for plant physiological research and disease diagnosis. By analyzing leaf samples, key physiological indicators such as the plant's nutritional status (e.g., nitrogen, phosphorus, and potassium content), photosynthetic efficiency, and metabolic product levels can be obtained. At the same time, it can detect pathogenic microorganism infections (e.g., fungi, bacteria, or viruses) at an early stage. This non-destructive sampling method provides a scientific basis for fertilizer regulation, pest and disease control, and variety improvement in precision agriculture, and helps to intervene in a timely manner to ensure tomato yield and quality.

[0003] CN217111575U discloses a leaf sampler, including a first body and a second body, which are rotatably connected by a pivot. The front ends of the first and second bodies are sampling mechanisms, and the rear ends are handles. A pressing plate is provided at the front end of the first body, and a support plate is provided at the front end of the second body. A pressing element is provided between the pressing plate and the support plate. The pressing element includes a punching post and a spring sleeved on the punching post. A through hole is provided on the support plate for the punching post to pass through. A leaf placement opening is provided on the side wall of the support plate, and the leaf placement opening is connected to the through hole. A sampling tube is provided at the lower end of the support plate, and the sampling tube is positioned corresponding to the through hole. This device can achieve rapid sampling and is easy to use. However, its drawback is that the sampling tube has a simple structure and can only perform single sampling. It cannot classify and store tomato leaves of different positions or varieties, resulting in low practicality. Therefore, a tomato leaf cutting and sampling device is needed. Utility Model Content

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a tomato leaf cutting and sampling device, including a sampling device housing 1 and a sampling tube sorting assembly. The sampling tube sorting assembly includes a sampling tube placement box 10, a base plate 12, side plates 13, a placement frame 14, a rectangular locking block 16, a rotating column 17, a connecting column 18, a return spring C19, and a rotating wheel 20. The sampling tube placement box 10 is fixedly connected to the bottom of the sampling device housing 1. The base plate 12 is located at the bottom of the sampling tube placement box 10. There are two side plates 13, both of which are fixedly connected to the surface of the base plate 12. Both side plates 13 are connected to the sampling tube placement box 10. The sampling tube placement box 10 is bolted together. There are two placement frames 14, both of which are rotatably connected inside the sampling tube placement box 10. The rotating column 17 is rotatably connected to the base plate 12. Both placement frames 14 are fixedly sleeved on the outer surface of the rotating column 17. The rectangular locking block 16 is slidably connected inside the rotating column 17. The connecting column 18 is slidably connected inside the rotating column 17. The reset spring C19 is fixedly connected to the bottom of the rotating column 17. The reset spring C19 is located below the base plate 12. The rotating wheel 20 is fixedly connected to the bottom of the reset spring C19. The rotating wheel 20 is fixedly connected to the sampling tube placement box 10.

[0025] Furthermore, the sampling tube placement box 10 has multiple sampling tubes 15 inside, and the surfaces of the two placement frames 14 are provided with placement slots 21 for placing the sampling tubes 15. The surface of the sampling device housing 1 is provided with a slot 11. The top of the rectangular block 16 extends into the slot 11 and engages with it. The top of the sampling device housing 1 is slidably connected to a limit rod 4. The top of the limit rod 4 is fixedly connected to a pressure plate 3. The opposite surfaces of the sampling device housing 1 and the pressure plate 3 are fixedly connected to a return spring A5. The inside of the sampling device housing 1 is slidably connected to a punching column 6. The top of the sampling device housing 1 is fixedly connected to a return spring B7. The top of the return spring B7 is fixedly connected to the punching column 6. The surface of the sampling device housing 1 is fixedly connected to a punching base 8. The surface of the punching base 8 is provided with a punching hole 9 that matches the punching column 6. The surface of the sampling device housing 1 is provided with a groove 2.

[0026] Furthermore, the blade is placed on top of the punching base 8, the pressure plate 3 is pressed down and the punching column 6 moves downward to cooperate with the punching base 8 to punch the blade. The cut blade sample falls into the sampling tube 15 through the punching hole 9 for storage. Then, the return spring B7 and return spring A5 drive the pressure plate 3 to reset, pull the rotating wheel 20 down and cooperate with the connecting column 18 to drive the rectangular card block 16 to move downward. The rectangular card block 16 disengages from the limit of the card slot 11. At this time, the rotating column 17 can be rotated by rotating the rotating wheel 20, thereby driving the placement frame 14 to rotate. By rotating the placement frame 14 ninety degrees, other sampling tubes 15 can be placed inside the punching base 8 to achieve sampling and storage of different blades. After the cutting is completed, the base plate 12 can be disassembled to remove the sampling tube 15 for subsequent operations.

[0027] Furthermore, a one-click rapid cutting mechanism is achieved through the linkage between the punching column and the base, and a double reset spring ensures continuous operation and avoids sample contamination. The rotary sampling tube classification component driven by the wheel can complete the classification and storage of multiple samples in a single operation, which solves the problem that the sampling tube has a single structure, can only perform single sampling, and cannot classify and store tomato leaves of different positions or varieties, resulting in low practicality.
