Description

Technical Field

[0001] This utility model relates to the field of rice seed germination technology, and in particular to a seed germination device for rice cultivation. Background Technology

[0002] Effective seed germination treatment is crucial in rice cultivation; in practical applications, rice seed germination devices typically require the following technologies:

[0003] 1. Seed soaking mechanisms, such as constant temperature seed soaking tanks and intelligent seed soaking boxes, enable seeds to fully absorb water at a suitable water temperature;

[0004] 2. Temperature control mechanisms, such as heating and cooling equipment, to ensure that the germination environment is maintained within a suitable temperature range;

[0005] 3. Humidity control mechanisms, such as humidifiers and dehumidifiers, ensure that the humidity in the germination space meets the requirements for seed germination.

[0006] Existing Chinese patent: A seed germination device for rice cultivation, publication number: CN222263577U, includes a bottom support, a soaking tank fixedly installed at the top of the bottom support, a movable frame slidably arranged in the soaking tank, a shaking component and a flipping component respectively provided on the movable frame, a feeding frame fixedly installed on one side of the movable frame, and the flipping component includes a flipping frame, with symmetrically distributed fixed shafts fixedly installed on the side of the flipping frame near the feeding frame, and the fixed shafts are rotatably connected to the movable frame; this utility model, by setting a shaking component, causes the movable frame to shake, and the shaking of the movable frame causes the flipping frame to shake in the soaking tank, which can promote the uniform soaking of rice seeds in the flipping frame to prevent accumulation, and the shaking can promote the discharge of clear water during the upward movement of the movable frame, thereby achieving the effect of uniform soaking of rice seeds.

[0007] However, during the implementation of the above technical solution, at least the following technical problems were found: The above germination device germinates seeds by soaking them in water. After soaking, the seeds need to be manually removed. It is difficult to control the timing of manually removing the seeds, and soaking for too long or too short a time will affect the germination effect. If the seeds are not removed, they will be ruined. Therefore, it is inconvenient to use. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a seed germination device for rice cultivation, solving the problem that the aforementioned germination devices germinate seeds by soaking them in water. After soaking, the seeds need to be manually removed, which is difficult to control in terms of timing. Soaking for too long or too short a time will affect the germination effect. If the seeds are not removed, they will be ruined. Therefore, this is a relatively inconvenient technical problem to use.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A seed germination device for rice cultivation includes a germination box with a soaking area and a settling area inside. A lifting box is slidably installed inside the germination box, and a seed tray is slidably installed inside the lifting box. A threaded rod is rotatably installed inside the germination box. Stepper motors are symmetrically fixed inside the germination box. A control box for controlling the stepper motors is fixedly installed inside the germination box. A control panel is fixedly installed on the germination box, and a glass door is slidably installed on the germination box. The stepper motors and the control panel are connected to the control box via wires. The lifting box and the threaded rod are threadedly connected. The stepper motor drives the threaded rod to rotate through a bevel gear set.

[0011] Preferably, a temperature sensor for measuring temperature and a humidity sensor for measuring humidity are fixedly installed inside the germination chamber; the temperature sensor and the humidity sensor are connected to the control box via wires.

[0012] Preferred configuration: An air pump is fixedly installed inside the germination box, a copper pipe is fixedly installed on the air pump, and an air stone is fixedly installed at the end of the copper pipe.

[0013] Preferred: An electric heating wire is wound around the gas stone.

[0014] Preferably, a power adapter is fixedly installed inside the germination box; the power adapter is connected to the heating wire and the control box via wires.

[0015] Preferably, a first filter screen is fixedly installed on the side of the germination box.

[0016] Preferably, a second filter screen is fixedly installed at the top of the germination box.

[0017] Preferably, a fan is fixedly installed at the top of the germination box; the fan is connected to the control box via a wire.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When using, fill the germination box with clean water to fill the soaking area. Push the two glass doors open to both sides, then pull out the tray and evenly scatter the seeds on the tray. Then close the glass doors. Set the soaking time through the control panel. The control box will synchronously drive two stepper motors to start. The stepper motors will drive the threaded rod to rotate counterclockwise. Since the threaded rod is threadedly connected to the lifting box, the lifting box will slide down, carrying the tray and seeds down to the soaking area for soaking. When the set soaking time is reached, the stepper motors will drive the threaded rod to rotate clockwise, causing the lifting box to slide back up to the resting area. This allows for precise control of the soaking time without the need for supervision, achieving a convenient user experience.

[0020] II. During use, temperature and humidity sensors monitor the temperature and humidity inside the germination chamber. When the temperature or humidity is too high, the fan will start to expel the humid air from inside the germination chamber. When the temperature and humidity are insufficient, the air pump will start to transport outside air along the copper pipe into the clean water inside the germination chamber. During this process, the air stone can make the gas more evenly distributed in the water, which helps to increase the oxygen content in the water and ensure that the seeds can breathe effectively. At the same time, the electric heating wire will start to heat the copper pipe, so that the temperature of the air as it passes through the copper pipe will rise, thereby raising the temperature inside the germination chamber. After the gas enters the clean water, it will fill the inside of the germination chamber. The air comes into contact with the water first and then enters the air, which can increase the humidity in the air and achieve the effect of automatically maintaining a suitable environment for seed germination inside the germination chamber.

[0029] This application provides a seed germination device for rice cultivation, effectively solving the problems of the aforementioned germination devices. These devices involve soaking seeds in water for germination, requiring manual removal after soaking. Manual removal is time-consuming and can affect germination efficiency if soaked for too long or too short a time. Forgetting to remove the seeds will damage them, making it inconvenient to use. In this new device, clean water is injected into the germination chamber to fill the soaking area. The two glass doors are pushed open, and the tray is pulled out to evenly distribute the seeds. The glass doors are then closed. The soaking time is set via the control panel, and the control box synchronously drives two stepper motors. These motors rotate a threaded rod counterclockwise. Because the threaded rod is threadedly connected to a lifting box, the lifting box slides downwards, carrying the tray and seeds down to the soaking area. After the set soaking time is reached, the stepper motors rotate the threaded rod clockwise. The needle rotates, causing the lifting box to slide upwards back to the resting area, allowing for precise control of soaking time. No supervision is required, making it easy to use. During operation, temperature and humidity sensors monitor the temperature and humidity inside the germination chamber. If the temperature or humidity is too high, the fan will activate to expel the humid air from the chamber. If the temperature and humidity are insufficient, the air pump will activate to deliver external air through copper pipes into the clean water inside the germination chamber. During this process, the air stone ensures more even gas distribution in the water, increasing the oxygen content and ensuring effective seed respiration. Simultaneously, the electric heating wire activates, heating the copper pipes and raising the temperature of the air passing through them, thus increasing the temperature inside the germination chamber. After entering the clean water, the gas fills the interior of the germination chamber. The air first contacts the water before entering the air, increasing humidity and automatically maintaining a suitable environment for seed germination inside the germination chamber.

The fan 19 is connected to the control box 6 through wires.

[0035] Germination box 1: The main structure of the entire device, with an internal soaking area and a settling area, supporting other components and providing working space;

[0036] Lifting box 2: Slides inside the germination box 1, driving the seed tray 3 to move up and down, realizing the conversion of seeds between the soaking area and the static area;

[0037] Net 3: Can be pulled out for placing seeds;

[0038] Threaded rod 4: drives the lifting box 2 to rise and fall by rotating it;

[0053] Working principle:

[0054] The first step is to fill the germination box 1 with clean water to fill the soaking area. Push the two glass doors 8 open to both sides, then pull out the tray 3 and evenly scatter the seeds on the tray 3. Then close the glass doors 8. Set the soaking time through the control panel 7. The control box 6 will synchronously drive the two stepper motors 5 to start. The stepper motors 5 will drive the threaded rod 4 to rotate counterclockwise. Since the threaded rod 4 is threadedly connected to the lifting box 2, the lifting box 2 will slide down. The lifting box 2 will carry the tray 3 and seeds down to the soaking area for soaking. When the set soaking time is reached, the stepper motors 5 will drive the threaded rod 4 to rotate clockwise, causing the lifting box 2 to slide up back to the resting area. This allows for precise control of the soaking time without the need for personnel to supervise, achieving a convenient operation.

[0055] In the second step, during use, the temperature sensor 9 and humidity sensor 11 will monitor the temperature and humidity inside the germination chamber 1. When the temperature or humidity is too high, the fan 19 will start to expel the humid air inside the germination chamber 1. When the temperature and humidity are insufficient, the air pump 12 will start to transport external air along the copper pipe 13 to the clean water inside the germination chamber 1. During this process, the air stone 14 can make the gas more evenly distributed in the water, which is conducive to increasing the oxygen content in the water and ensuring that the seeds can breathe effectively. At the same time, the electric heating wire 15 will start to heat the copper pipe 13, so that the temperature of the air increases when it passes through the copper pipe 13, thereby increasing the temperature inside the germination chamber 1. After the gas enters the clean water, it will fill the inside of the germination chamber 1. The air comes into contact with the water first and then enters the air, which can increase the humidity in the air, thus achieving the effect of automatically maintaining a suitable environment for seed germination inside the germination chamber 1.
