[0010] Preferably, the feeding hopper is provided with a protective cover for auxiliary light shielding, the protective cover can contact the inner wall of the feeding hopper, and the top of the protective cover is provided with a pull ring.

[0011] Preferably, the mixing tank has a handle on one side for providing an operating grip point, the protective cover is covered with a silicone ring for increasing the sealing degree to prevent light leakage, and the bottom of the mixing tank is provided with support legs.

[0012] Compared with related technologies, the liquid fertilizer solubility detection device provided by this utility model has the following beneficial effects:

[0013] This utility model provides a device for detecting the solubility of liquid fertilizer:

[0014] 1. By setting up a mixing tank as the main space for water-fertilizer mixing, the mixing tank ensures that water and fertilizer can fully contact and dissolve. The cylinder not only provides stable support for the feeding hopper but also ensures the accuracy of feeding and avoids fertilizer spillage during the addition process. The feeding hopper makes it convenient for users to add solid water-soluble fertilizer to the mixing tank. Its design simplifies the feeding process and improves the convenience of operation. The discharge pipe extends from the bottom of the feeding hopper into the mixing tank, ensuring that fertilizer can fall directly and accurately into the mixture, reducing the possibility of waste and pollution. The plug is used to seal the discharge pipe to prevent accidental leakage of fertilizer when feeding is not needed. The design of the plug increases the flexibility and safety of the device. The stirring structure can automatically and continuously stir the water and fertilizer in the mixing tank. This structure effectively improves the fertilizer dissolution efficiency and reduces the labor required for manual stirring. The detection structure can monitor the turbidity of the mixture in real time, thereby indirectly reflecting the degree of fertilizer dissolution. Compared with visual observation, this detection method is more objective and accurate, improving the precision and reliability of solubility detection.

[0015] 2. A fixed frame provides a stable support platform for the stirring rod, ensuring its stability and reliability during the stirring process. The stirring rod rotates to thoroughly agitate the water and fertilizer in the mixing tank. The shape and length of the stirring rod are carefully designed to ensure uniform mixing of the mixture, thereby improving fertilizer dissolution efficiency. A servo motor serves as the power source for the stirring rod; precise control of its speed and direction allows for flexible adjustment of the stirring speed and method. The stirring structure ensures thorough agitation of the water and fertilizer in the mixing tank, accelerating fertilizer dissolution and improving efficiency. The protective shell primarily serves to shield light, ensuring that the light is not disturbed during testing and improving accuracy. The system consists of a lighting unit, a light source, and a light detector. The lighting unit emits light that penetrates the mixed liquid to observe and analyze the fertilizer's solubility. The first focusing box concentrates the light emitted by the lighting unit, enhancing its penetration into the mixed liquid. The second focusing box, in conjunction with the bottom light-transmitting plate, also focuses the light, ensuring that the light can evenly illuminate different depths of the mixed liquid. The light-transmitting plate allows light to pass through and is a key component for the light to enter the mixing tank and penetrate the mixed liquid. The light detector receives the light after it has penetrated the mixed liquid. By analyzing parameters such as the light intensity and wavelength, the degree of fertilizer solubility and the turbidity of the mixed liquid can be indirectly determined. The combined design of the lighting unit, focusing box, and light detector can be adjusted and optimized according to different detection needs and fertilizer types, improving the flexibility and applicability of the detection.

[0016] 3. A convex lens has the characteristic of converging light, which can further enhance the intensity and focusing effect of the light emitted by the lighting lamp when penetrating the mixed liquid. This allows the photodetector to receive a clearer and stronger light signal. An aperture is a device that limits the width and direction of the light beam. It ensures that only light rays of a specific angle and range can pass through, thus avoiding stray light interference and improving light utilization and detection accuracy. The display can show the light scattering state in real time, that is, the scattering of light after penetrating the mixed liquid. By observing the image or data on the display, users can directly understand the fertilizer's dissolution state and the turbidity of the mixed liquid without performing complex subsequent analysis, thus enhancing [the system's capabilities]. The user experience and satisfaction are enhanced by the observation window, which allows users to intuitively observe the water level inside the mixing tank. This design greatly facilitates monitoring and adjustment during water and fertilizer mixing. The scale lines provide users with a precise reference system. By observing the relative position of the water level and the scale lines, users can quickly and accurately understand the amount of water in the mixing tank, thereby ensuring precise control of the water-fertilizer ratio. The light shield is designed to cover the observation window, effectively blocking external light from interfering with the view inside the window. This function is especially important in scenarios with strong light or where it is necessary to avoid light affecting the accuracy of observation. The adhesive sheet can be tightly adhered to the outer wall of the mixing tank, ensuring the stability and durability of the light shielding effect.

[0017] 4. The main function of the protective cover is to assist in shading, ensuring that the light inside the feeding hopper does not interfere with the outside environment when adding fertilizer or other materials. It also avoids the potential impact of external light on the feeding process. In addition, the protective cover can prevent dust and impurities from entering the feeding hopper to a certain extent, maintaining a clean feeding environment. The protective cover can make close contact with the inner wall of the feeding hopper; this design ensures the stability and durability of the shading effect. The pull ring provides users with a convenient way to open and close the protective cover. Users can easily open or close the protective cover with a gentle pull, without using additional tools or force. The device provides a convenient grip point, allowing users to easily operate it when moving, carrying, or adjusting the position of the mixing tank, greatly improving ease of operation and safety. The silicone ring has good elasticity and sealing performance. When the protective cover is closed, the silicone ring can fit tightly against the inner wall of the feeding hopper, effectively blocking light from leaking out from the gaps. This design not only improves the light-blocking effect but also ensures the cleanliness of the inside of the feeding hopper and the safety of the materials. The support legs allow the mixing tank to be placed stably on the ground, maintaining its stability and safety even during operation or movement. Attached Figure Description
