[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] like Figure 1-3 The watermelon seed germination device shown includes a box containing a soaking solution and a box cover that is hinged to the top of the box cover. Inside the box is a support frame that moves up and down in the soaking solution. Inside the support frame is a base plate mechanism that carries seeds. The base plate mechanism can pass through the soaking solution and is detachable within the support frame. Seeds can enter the soaking solution for soaking and rise above the soaking solution for germination by moving the support frame up and down. A lifting component that drives the up and down movement of the support frame is provided below the support frame.

[0021] Based on the above, the box provides a space for soaking solution, and the box lid can be closed to form a relatively closed environment; the supporting frame serves as the carrier of the base plate mechanism, and is driven up and down by the lifting component to drive the base plate mechanism and seeds into the soaking solution to complete the soaking, or to rise above the liquid surface for germination, realizing the automated switching of the "soaking-germination" process; the detachable design of the base plate mechanism facilitates the loading and unloading of seeds, ensuring smooth operation.

[0022] Furthermore, the integrated structure enables seamless integration of seed soaking and germination, eliminating the need for manual seed transfer and improving efficiency; the detachable base plate facilitates cleaning and seed replacement, adapting to different batch germination needs.

[0023] The bottom of the inner cavity of the box is equipped with several heating tubes that are offset from the lifting components, and the heating tubes are immersed in the soaking liquid.

[0024] Based on the above, the heating tube generates heat after being powered on, directly heating the soaking solution inside the chamber. By adjusting the power, the soaking solution is maintained at the appropriate temperature required for seed soaking, ensuring that the seeds are in a stable temperature environment during the sterilization and water absorption stages, and avoiding the sterilization effect or water absorption efficiency being affected by insufficient temperature.

[0025] An ultrasonic generator, offset from the lifting component, is installed at the bottom of the inner cavity of the box and is immersed in the soaking liquid.

[0026] Based on the above, the ultrasonic generator produces high-frequency vibrations when it is working, which creates a cavitation effect (generating tiny bubbles and breaking them) in the soaking solution. On the one hand, the vibration promotes the circulation of the soaking solution, allowing the seeds to fully contact the liquid, accelerating the softening of the seed coat and the absorption of water. On the other hand, the local energy generated by the cavitation effect can help remove pathogens on the seed surface, enhance the bactericidal effect, and synergistically improve the pretreatment effect with warm water soaking.

[0027] The supporting frame includes an annular outer frame with a hollow interior. A connecting rod is connected between the two sides of the outer frame along its long axis. The surface of the connecting rod protrudes upward. An annular magnetic suction plate is installed at the bottom of the inner side of the outer frame. Magnetic suction cups are symmetrically arranged through the connecting rod.

[0028] Based on the above, the outer frame provides installation space for the base plate mechanism, and its ring structure adapts to the internal contour of the box to ensure that it does not interfere with the box wall during lifting; the connecting rod connects the two sides of the outer frame to form a support structure, which facilitates connection with the lifting components; the raised surface can support the folding plate of the base plate mechanism to prevent the base plate mechanism from sinking; the magnetic plate attracts the magnetic strip of the base plate mechanism through magnetic force to achieve stable fixation of the base plate mechanism within the bearing frame, and avoid the base plate mechanism from shaking or falling off during lifting.

[0029] The base plate mechanism includes an inner frame located inside the outer frame. The outer side wall of the inner frame is attached to the inner side wall of the outer frame. An upwardly protruding folding plate is provided between the two sides of the inner frame in the long axis direction. The bottom of the folding plate is attached to the surface of the connecting rod.

[0030] The bottom of the inner frame is fitted with a magnetic strip that attracts the magnetic plate.

[0031] Based on the above, the inner frame is used to hold the seeds, and its outer side wall fits against the inner side wall of the outer frame to ensure that it does not shake during lifting and lowering; the folded plate protrusion structure fits against the protrusion connecting rod of the supporting frame to form a support point, restricting the vertical displacement of the inner frame within the supporting frame and preventing the inner frame from sinking due to gravity; the magnetic strip and the magnetic suction plate of the outer frame are magnetically attracted to each other to further fix the inner frame, preventing it from moving laterally or tilting during lifting and lowering, and ensuring that the seeds are stably placed in the inner frame;

[0032] Furthermore, the raised surface of the folding plate can prevent seeds from accumulating in the area above the connecting rod where there are no through holes, thus affecting seed germination.

[0033] Several through holes are evenly provided at the bottom of the inner frame located on both sides of the folding plate, and a handle is installed at the top of the inner frame;

[0034] Based on the above, the through holes at the bottom of the inner frame allow the soaking solution to freely enter and exit, ensuring that the seeds are fully in contact with the liquid during the soaking stage, achieving uniform water absorption and sterilization; during the germination stage, the through holes can quickly drain excess water from the seed surface, preventing water accumulation that could cause the seeds to rot; the handle makes it easy for operators to grab the inner frame, enabling the base plate mechanism to be quickly removed from the supporting frame, facilitating the loading and unloading of seeds.

[0035] The lifting component includes a servo push rod installed at the bottom of the housing. The output shaft of the servo push rod extends upward through the housing and into the housing. A mechanical seal is provided at the connection between the output shaft of the servo push rod and the housing. The top end of the output shaft of the servo push rod is fixedly connected to the bottom of the middle section of the connecting rod. Telescopic rods are connected between the two ends of the connecting rod and the bottom of the inner cavity of the housing.

[0036] Based on the above, the servo push rod drives the support frame and base plate mechanism to move up and down through the extension and retraction of the output shaft. When it extends, it sends the seed into the soaking solution to complete the soaking, and when it retracts, it raises the seed above the liquid surface to promote germination. The mechanical seal forms a seal at the point where the output shaft of the servo push rod passes through the housing to prevent the soaking solution from leaking out of the gaps. The telescopic rod extends and retracts synchronously with the servo push rod to assist in supporting both ends of the support frame, preventing the support frame from tilting due to uneven force during lifting and ensuring a smooth lifting process.

[0037] A drain pipe is installed on the outer wall at the bottom of the box for discharging the soaking solution. A temperature sensor is installed at the bottom of the inner cavity of the box, and support frames are installed at the four corners of the box.

[0038] Based on the above, the device is connected to a control center to control the servo push rod. At the same time, the temperature sensor monitors the temperature of the soaking solution in real time and feeds the data back to the control system. Working together with the heating tube, the temperature of the soaking solution is stabilized within the set range by adjusting the power of the heating tube. The support frame supports the bottom of the box, keeping the box away from the placement surface to avoid heat loss or moisture caused by the box directly contacting the ground, while also improving the overall stability of the device.

[0039] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
