Description

Technical Field

[0001] This utility model relates to the field of rice seedling soaking technology, specifically a rice seedling soaking device. Background Technology

[0002] Current Status of Rice Seed Soaking Technology: Before rice seedling cultivation, seeds need to be soaked to promote germination and kill pathogens. Traditional soaking methods mainly include two types: static soaking and simple aerated soaking. Static soaking: The seeds are placed directly into a container and soaked in water. The operation is simple, but it can easily lead to insufficient oxygen supply, causing the seeds to rot and resulting in a low germination rate. Simple aeration soaking: Oxygen is increased by using a regular air pump or manual stirring, but the bubbles are unevenly distributed, the soaking effect is unstable, and the operation is cumbersome; Problems with existing technology: Uneven oxygen supply: Traditional aeration methods (such as single air tubes) result in concentrated air bubbles, which can lead to oxygen deficiency in areas where seeds are piled up, affecting the uniformity of germination. The aeration holes are also easily blocked by seeds or impurities, resulting in localized areas without air bubbles. The seed soaking frame design is unreasonable: If the filter holes are too large, seeds will easily leak out; if they are too small, drainage will be poor, affecting the penetration of the pesticide. If the seed soaking frame is not fixed, it will easily tilt when it is picked up or placed, causing the seeds to spill out. Low operational efficiency: Incomplete drainage leaves residual liquid that affects the effectiveness of subsequent seed soakings. The lack of a quick-positioning structure means that the seed position needs to be repeatedly adjusted when changing seeds. Summary of the Invention

[0003] In view of the shortcomings of the prior art, this utility model provides a seed soaking device for rice seedling cultivation to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A rice seed soaking device for rice seedling cultivation includes: Soaking box components: A square seed soaking box with four legs at the bottom to support the seed soaking box on the working surface; The drain pipe runs horizontally through the side wall of the seed soaking tank near the bottom, and valves are installed on the pipe to control the liquid discharge. Aeration components: The mounting bracket is fixedly welded to the outer wall of the soaking box; The aerator is fixed on the mounting frame, and its output end is connected to a connecting pipe; Multiple aeration pipes are arranged horizontally and penetrate the side wall of the seed soaking box. Each aeration pipe is connected to the aerator through a connecting pipe, and aeration holes are evenly distributed on the pipe wall. Seed soaking frame component: Four support plates are symmetrically fixed to the inner side wall of the soaking tank to form a support track; The seed soaking frame has multiple sets of filter holes at the bottom and handles on both sides at the top. The seed soaking frame can be detachably installed in the seed soaking box by interlocking with the support plate through four positioning rods, and a gap is left between the bottom surface of the seed soaking frame and the aeration pipe.

[0005] Preferably, the valve of the drain pipe is a manual ball valve or a solenoid valve, and its inlet is located at the lowest liquid level in the seed soaking tank.

[0006] Preferably, the aeration holes of the aeration pipe have a diameter of 0.5-2 mm, a hole spacing of 10-20 mm, and the spacing between adjacent aeration pipes is no greater than 1 / 3 of the width of the soaking box.

[0007] Preferably, the positioning rod is a cylindrical stainless steel rod with a tapered guide at its lower end, and a blind hole that fits the positioning rod with a clearance, the depth of which is 1 / 3 to 1 / 2 of the length of the positioning rod.

[0008] Preferably, the filter holes of the soaking frame are arranged in a matrix, with a hole diameter of 3-5 mm and a hole spacing of 8-12 mm, and the total area of ​​the filter holes accounts for 30%-50% of the bottom area of ​​the soaking frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. This rice seed soaking device improves the uniformity of soaking and germination rate. The aeration system provides a continuous and uniform oxygen supply, preventing seeds from rotting or germinating unevenly due to lack of oxygen. The agitation of the bubbles promotes the uniform distribution of the soaking solution, ensuring that each seed can fully contact the effective ingredients and improve the soaking effect. The optimized spacing and aperture of the aeration pipes ensure that the bubbles cover the entire soaking area without dead corners.

[0010] 2. This rice seed soaking device is easy to operate and improves work efficiency. The detachable design of the soaking frame facilitates quick loading and unloading of seeds, reducing manual operation time. The optimized design of the filter holes can effectively drain water and prevent seeds from leaking out. The low-positioned drain pipe can completely empty the soaking solution, making it easy to replace different concentrations of agents or clean the tank.

[0011] 3. This rice seed soaking device features a square soaking box and support plate to ensure accurate positioning of the soaking frame and prevent deviation from affecting the aeration effect. The conical guide of the positioning rod and the gap fit make the installation of the soaking frame smoother and reduce wear. The stainless steel material (such as the positioning rod) is corrosion resistant and suitable for long-term water immersion environments.

[0012] 4. This rice seedling soaking device has valves that can be manually or electromagnetically controlled, making it suitable for seedling raising scenarios with different levels of automation. The aeration system is adjustable to meet the soaking requirements of different seed varieties (such as time and oxygen content). The modular design facilitates maintenance, such as replacing aeration pipes or soaking frames. Attached Figure Description

[0015] 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. Example 1

[0016] Please refer to Figures 1-4. A rice seed soaking device for rice seedling cultivation includes: Soaking box component 1: A square seed soaking box 1 has four support legs 7 at its bottom to support the seed soaking box 1 on the working surface; Drainage pipe 2 runs horizontally through the side wall of the seed soaking tank 1 near the bottom, and a valve is installed on the pipe to control the liquid discharge; Aeration components: Mounting bracket 6 is fixedly welded to the outer wall of the seed soaking box 1; Aerator 5 is fixed on mounting bracket 6, and its output end is connected to connecting pipe 12; Multiple aeration pipes 3 are arranged horizontally and penetrate the side wall of the seed soaking box 1. Each aeration pipe 3 is connected to the aerator 5 through a connecting pipe 12, and aeration holes are evenly distributed on the pipe wall of the aeration pipe 3. 8-component soaking frame: Four support plates 4 are symmetrically fixed to the inner side wall of the soaking tank 1 to form a support track; The seed soaking frame 8 has multiple sets of filter holes 10 at its bottom and handles 9 on both sides at the top. The seed soaking frame 8 is detachably installed in the seed soaking box 1 by the insertion and cooperation of four positioning rods 11 with the support plate 4, and a gap is left between the bottom surface of the seed soaking frame 8 and the aeration pipe 3. Specifically, the square soaking box 1 serves as the core container, holding the soaking solution such as water or chemical solution. The square structure facilitates alignment and installation with components such as the support plate 4 and the aeration pipe 3. The support leg 7 raises the height of the seed soaking tank 1, facilitating the operation of the drain pipe 2 and bottom cleaning; Drain pipe 2: The discharge of the soaking solution is controlled by a valve. When the valve is closed, the solution is kept in place for soaking the seeds. When the valve is opened, the solution is drained quickly, such as when changing water or when the operation is completed. Aerator 5: generates high-pressure air, which is delivered to aeration pipe 3 through connecting pipe 12; Aeration pipe 3: Air escapes from the aeration holes to form tiny bubbles, which diffuse evenly in the soaking solution, providing oxygen to the rice seeds to prevent anaerobic fermentation, while promoting liquid flow to ensure even distribution of the agent. Support plate 4: The inner support rail guides the vertical lifting of the soaking frame 8 to ensure positioning accuracy; Filter hole 10: Allows the soaking solution to flow freely, but prevents rice seeds from leaking out; Positioning rod 11: It is inserted into the blind hole of the support plate 4 to prevent the seed soaking frame 8 from shifting horizontally and to ensure that the gap between it and the aeration pipe 3 is constant to avoid seeds clogging the aeration holes. Handle 9: Facilitates lifting the soaking basket 8 to inspect or transfer seeds; In the embodiment: the valve of the drain pipe 2 is a manual ball valve or a solenoid valve, and its inlet is located at the lowest liquid level in the seed soaking tank 1; Specifically, manual ball valves offer low-cost and reliable control, while solenoid valves provide automated control, depending on the requirements. The inlet is positioned at the lowest liquid level to ensure thorough drainage without any residue. Thorough drainage prevents bacteria growth in stagnant water and facilitates the replacement of different concentrations of chemical solutions. In the embodiment: the diameter of the aeration holes of the aeration pipe 3 is 0.5-2mm, the hole spacing is 10-20mm, and the spacing between adjacent aeration pipes 3 is not greater than 1 / 3 of the width of the soaking box 1. Specifically, the diameter of the aeration holes should be 0.5-2mm: forming bubbles of the appropriate size. If the bubbles are too large, they will damage the seeds; if they are too small, they will not provide enough oxygen. The spacing between the holes should be 10-20mm and the spacing between the holes and the aeration pipe 3: ensuring that the bubbles cover the entire soaking area, with no dead corners for oxygen supply. Uniform aeration can improve the germination rate of seeds and avoid local hypoxia that can lead to mold. In the embodiment: the positioning rod 11 is a cylindrical stainless steel rod with a tapered guide at its lower end. The support plate 4 has a blind hole that fits the positioning rod 11 with a clearance. The depth of the blind hole is 1 / 3 to 1 / 2 of the length of the positioning rod 11. Specifically, the tapered guide section guides the positioning rod 11 to be quickly inserted into the blind hole, reducing the difficulty of alignment; the clearance fit allows for small tolerances and avoids jamming; the depth of the blind hole is limited to 1 / 3-1 / 2 of the rod length to ensure stability and easy separation, enabling quick assembly and disassembly of the seed soaking frame 8 while maintaining its levelness; In the embodiment: the filter holes 10 of the seed soaking frame 8 are arranged in a matrix, with a hole diameter of 3-5 mm and a hole spacing of 8-12 mm, and the total area of ​​the filter holes 10 accounts for 30%-50% of the bottom area of ​​the seed soaking frame 8; Specifically, the aperture is 3-5mm, much smaller than the size of rice seeds, which is usually >5mm, to prevent seed leakage. The matrix distribution and hole spacing balance drainage efficiency and structural strength. The total area accounts for 30%-50% to ensure liquid exchange rate, such as chemical penetration, and reliable load-bearing capacity. Water flows smoothly during seed soaking and drains quickly when the frame is lifted. In this embodiment: the aerator 5 is an existing structure, and the control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the art, and it is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0017] Working principle: Place rice seeds in the soaking frame 8, inject soaking solution (clean water or chemical solution) into the soaking tank 1, start the aerator 5, and air enters the aeration pipe 3 through the connecting pipe 12. The small holes on the aeration pipe 3 generate a large number of bubbles, providing oxygen to the seeds. The bubbles agitate the soaking solution, making the temperature and chemical distribution uniform. After soaking, open the valve of the drain pipe 2 to drain the liquid. Lift the soaking frame 8 through the handle 9, and the water filter hole 10 automatically drains the water. The positioning rod 11 ensures that the soaking frame 8 is raised and lowered smoothly. The aeration system prevents the seeds from rotting due to lack of oxygen. The soaking frame 8 can be easily removed for easy seed transfer. The entire device has a simple structure and is easy to operate. Through the aeration and oxygen supply and convenient pick-up and drop design, this device achieves efficient and uniform soaking treatment of rice seeds.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
