Description

Technical Field

[0001] This invention relates to the field of pH detection devices, and in particular to a pH detection device for blueberry substrate cultivation. Background Technology

[0002] Substrate cultivation, as a core technology for upgrading the blueberry industry, has become the mainstream model for high-quality blueberry cultivation worldwide. Due to their shallow root system and lack of root hairs, blueberries have strict requirements for the pH of their growing environment. When the pH is too low, blueberries are prone to iron absorption problems, leading to growth disorders such as yellowing leaves. Conversely, excessively low pH may cause heavy metal poisoning, seriously affecting fruit yield and quality. Currently, in blueberry substrate cultivation practices, pH monitoring mainly relies on sampling and testing. Therefore, a detection device is needed to facilitate the detection and treatment of pH in blueberry substrate cultivation.

[0003] Currently, traditional detection devices mainly use electronic pH meters for detection. This involves mixing the sample with distilled water in a specific ratio and then immersing the electrode probe in the clarified liquid. However, the sampling, mixing, and detection processes require operation in various containers, resulting in a large number of instruments and complicated steps, making it inconvenient for detection. Summary of the Invention

[0007] Preferably, the support frame is configured as an L-shaped bracket; the detection rod is electrically connected to the detection component and control center inside the detection base block; the interior of the material loading base cylinder is configured as a cavity structure, and threaded through holes are respectively opened on the upper and lower sides of the material loading base cylinder, and the bottom thread of the material loading base cylinder is threadedly connected to the thread of the detection base block.

[0008] Preferably, the connecting block is configured as a cylindrical structure, and threads are respectively provided on the upper and lower sides of the connecting block. The lower thread of the connecting block is threadedly connected to the top thread of the material loading bottom cylinder. The adjusting inner groove is connected with rectangular through holes distributed in a circle, and the top of the adjusting inner groove is connected with a circular through hole.

[0009] Preferably, the outer wall of the inner adjusting frame is fixed with a cuboid structure for sliding connection within a rectangular through hole in the adjusting inner groove; the outer adjusting ring is slidably connected to the outside of the connecting block; the connecting leak hole is a circular through hole, and a conical groove is connected to the top of the connecting leak hole.

[0010] Preferably, the bottom of the top cover frame is provided with a cylindrical rod for sliding connection in the circular through hole of the adjusting inner groove, the cylindrical rod of the top cover frame is fixed to the top of the inner adjusting frame, and a spring is sleeved on the outside of the cylindrical rod of the top cover frame; the inner plug can be inserted into the conical groove of the corresponding connecting leakage hole.

[0015] The blueberry substrate cultivation pH detection device provided by this invention has the following beneficial effects: In this invention, the detection base block serves as the core mounting carrier. Through a precise fit between the top thread and the material-carrying base cylinder, a rigid connection between the detection component and the storage structure is achieved. The detection base block houses the detection component and the control center, with the detection rod directly electrically connected to both. This eliminates the need for intermediate transmission of the detection signal, and the detection results are visualized through the linkage between the external display screen and the control center. The material-carrying base cylinder not only accommodates the sample water and ensures full contact between it and the detection rod, but also prevents the sample water from evaporating or being mixed with external impurities, facilitating the detection and processing of the sample water.

[0016] In addition, the design of the inner plug and the conical surface of the top conical groove of the connecting leak hole achieves contact sealing. With the spring reset structure on the bottom cylindrical rod of the top cover frame, the seal is automatically achieved after the outer adjusting ring is released, ensuring that the sample water is accurately delivered to the bottom cylinder as needed. The integrated connection structure of the outer adjusting ring and the inner adjusting frame allows the operator to simply push the outer adjusting ring upward to move the inner adjusting frame and the top cover frame upward synchronously, so as to open the connecting leak hole and facilitate the transportation and processing of sample water.

[0017] In addition, the inner ring on the inner wall of the immersion top cylinder engages with the outer wall protrusion of the loading cylinder through a retaining ring, so that the loading cylinder is suspended inside the immersion top cylinder, forming a double-layer space. After distilled water is injected into the outer space, it circulates through the external leakage hole on the outer wall of the immersion top cylinder, ensuring that the distilled water and the matrix sample in the loading cylinder are in full contact. The loading cylinder is engaged with the inner ring through the protrusion, which enables quick loading and unloading. Operators can directly remove the loading cylinder for sample loading and cleaning, which enhances the adaptability of the device.

[0018] In addition, the inner paddles distributed around the bottom of the inner adjusting rod extend into the filling cylinder. Rotating the top adjusting block will drive the inner paddles to rotate synchronously, thereby directly agitating the matrix sample and ensuring that the matrix and distilled water are mixed evenly.
