Description

Technical Field

[0001] This utility model relates to the field of agricultural intelligent equipment technology, specifically to a seed germination box based on visual observation. Background Technology

[0002] In agricultural seed quality testing and breeding research, seed germination rate is a core indicator for measuring seed vigor; traditional seed germination boxes rely on manual, periodic opening and observation, which has the following technical drawbacks: (1) Most germination boxes rely on manual timed opening to observe the germination status of seeds. At the same time, the germination status of seeds is also observed at close range through the observation port, which limits the scope of manual observation. Furthermore, manual observation of seed germination status is easily limited by perspective and subjective judgment, making it difficult to meet the research needs of subtle changes in seed germination. (2) Traditional germination boxes mostly use simple latches or snap-locks, so the latches or snap-locks need to be operated repeatedly when opening and closing the germination box, which increases the number of steps required to open and close the door. (3) The trays in traditional germination boxes are basically fixed structures, so the seeds in the trays are prone to uneven light exposure and uneven moisture, making it difficult to maintain a constant temperature and humidity environment. Especially when cultivating special crop seeds that are sensitive to the environment, the germination rate is easily reduced due to uneven environment. In addition, the tray is an integral structure, and it is more troublesome to assemble, disassemble and clean the tray, which reduces the stability and convenience of the germination box.

To prevent fluctuations in parameters such as temperature and humidity; an annular groove is provided at the upper part of the vertical positioning rod 201, and a positioning ring is provided at the bottom of the positioning cap 202, extending into the interior of the annular groove. The vertical positioning rod 201, positioning cap 202, and locking block 203 cooperate to form the locking structure 2. Specifically, the cooperation between the positioning ring and the annular groove enables the positioning cap 202 and the vertical positioning rod 201 to be circumferentially positioned, preventing the positioning cap 202 from moving up and down and ensuring the stability of the locking structure 2. The locking structure 2 achieves automatic locking and unlocking of the revolving door 102 through the elastic force of the support spring and the engagement of the locking block 203 with the locking groove, which is convenient to operate and reliable in locking. The rotating shaft 302 has cylindrical upper and lower ends and a hexagonal middle section. The upper end of the rotating shaft 302 connects to the drive shaft of the electric motor 301. The connection position of the drive shaft and the rotating shaft 302 is positioned using a conventional keyway. The electric motor 301 and the rotating shaft 302 cooperate to form the rotating mechanism 3. Two storage disks 4 form a group. Each storage disk 4 has a semi-circular structure. The two storage disks 4 are joined together to form a circular structure. A bolt mounting hole is provided on each side of each storage disk 4. Matching bolts are installed on the inner side of these holes as needed. After installation, the two storage disks 4 are securely joined. Specifically, the hexagonal middle structure of the rotating shaft 302 mates with the mounting groove of the storage disk 4, enabling circumferential transmission between the storage disk 4 and the rotating shaft 302. This ensures that the storage disk 4 rotates synchronously when the electric motor 301 drives the rotating shaft 302. The semi-circular design of the storage disks 4 facilitates installation and disassembly, and can be customized according to actual needs. The number of storage trays 4 needs to be adjusted to improve the flexibility of the equipment. A mounting groove corresponding to the hexagonal corner of the rotating shaft 302 is opened at the center of each storage tray 4. The rotating shaft 302 passes through the interior of the mounting groove. A horizontal support block with a cylindrical structure is provided on the inner side of the mounting groove. A set of positioning holes is opened at the hexagonal corner of the rotating shaft 302, and the support block extends into the interior of the positioning holes. Specifically, the cooperation between the support block and the positioning holes achieves axial positioning of the storage tray 4 and the rotating shaft 302, preventing the storage tray 4 from moving up and down during rotation, ensuring the stability and reliability of the storage tray 4's rotation, and ensuring that the seeds are evenly stressed on the storage tray 4. A set of storage troughs is opened around the periphery of the storage tray 4, and a set of drainage holes 401 is opened at the bottom of the storage troughs. Specifically, the storage troughs provide space for the seeds, facilitating orderly placement of the seeds; the drainage holes 401 can promptly drain excess water from the storage troughs, preventing the seeds from rotting due to soaking in water, and ensuring a suitable humidity environment for seed germination. The incubator 1 is equipped with an electric motor 301 and a camera 6 on its top. Each electric motor 301 and camera 6 is set to one. A set of bolt mounting holes are opened at the corners of the electric motor 301 and camera 6. The bolt mounting holes are positioned according to actual needs to install matching bolts. The camera 6 is selected from existing technologies that can automatically adjust the observation angle. A mounting hole is opened at the top of the incubator 1. The mounting hole is a cylindrical structure. The camera 6 extends into the interior of the incubator 1 through the inner side of the mounting hole. The specific function of the mounting hole is to provide a precise positioning and installation channel for the camera 6, so that the camera 6 can extend to a suitable position inside the incubator 1 to clearly capture the germination status of the seeds inside the box, while ensuring the stability and sealing of the camera 6 installation to prevent the leakage of environmental parameters inside the box. The incubator 1 has a rotating hole at its top and bottom, respectively, with the two rotating holes aligned. A rotating shaft 302 is installed between the two rotating holes. Two sets of storage trays 4 are installed on the outer side of the rotating shaft 302, and the number of storage trays 4 can be increased or decreased as needed. A spray sleeve 5 is inserted inside the incubator 1. A set of temperature control lamps is installed on the inner side of the incubator 1, and the model of the temperature control lamps is based on the commonly used model for seed irradiation. The spray sleeve 5 is stepped, and a locking nut is installed on one side of the spray sleeve 5. The locking nut and the external thread of the spray sleeve 5 are machined according to actual needs. A transverse positioning rod 501 is provided on one side of the spray sleeve 5. A set of sliding holes is opened on one side of the incubator 1. The transverse positioning rod 501 passes through the interior of the sliding holes. Its specific function is: the cylindrical stepped spray sleeve 5 cooperates with the mounting hole of the incubator 1 and is fixed by the locking nut to ensure the sealing and stability of the spray sleeve 5 installation; the cooperation between the transverse positioning rod 501 and the sliding hole restricts the axial movement of the spray sleeve 5. A spray hole is opened at the bottom of the spray sleeve 5. The spray hole is aligned with the storage tank of the storage tray 4. Its specific function is: the alignment design of the spray hole and the storage tank ensures that water or nutrient solution can be accurately sprayed into the storage tank where the seeds are located, avoiding spraying to other areas and causing waste or impact, ensuring that the seeds receive a uniform water supply and promoting seed germination. Set up a water pump and install it in a suitable position outside the incubator 1. Connect one end of the drainage pipe to the water pump outlet and the other end through the reserved hole in the incubator 1 to connect to the inlet of the spray sleeve 5, ensuring that the interface is sealed and leak-proof and that the water path is unobstructed.

[0019] The installation, operation process, and usage of this visual observation-based seed germination box embodiment are as follows: Place the incubator 1 on a horizontal platform and install the rotating door 102 to the side of the incubator 1 using a hinge; pass the vertical positioning rod 201 through the sliding hole of the positioning block 101, and fit a support spring on the outside of the rod body. The lower end of the spring abuts against the positioning plate 10201, and the upper end is fitted with a positioning cap 202, so that the positioning ring of the positioning cap 202 is embedded in the annular groove of the vertical positioning rod 201, thus completing the assembly of the locking structure 2; Insert the rotating shaft 302 into the upper and lower rotating holes of the incubator 1, connect the drive shaft of the electric motor 301 to the upper end of the rotating shaft 302 through the keyway, and fix the electric motor 301 to the top of the incubator 1 with bolts. Two semi-circular storage disks 4 are bolted together to form a disk. The central mounting groove is aligned with the hexagonal structure of the rotating shaft 302. The storage disk 4 is pushed so that the support block is embedded in the positioning hole of the rotating shaft 302, thus completing the axial positioning of the storage disk 4. Pass the spray sleeve 5 through the mounting hole on the side of the incubator 1, tighten the locking nut to fix it, and adjust the horizontal positioning rod 501 so that the spray hole is aligned with the storage tank of the storage plate 4. Pass the camera 6 through the mounting hole at the top of the incubator 1, adjust it to an angle that can cover all the storage trays 4, and fix it with bolts to ensure that the camera 6 can automatically adjust the shooting angle. Temperature control light debugging: Install a temperature control light inside incubator 1, and test the light intensity and temperature regulation function after powering on to ensure that it meets the requirements for seed germination, such as a constant temperature of 25℃. To open the rotating door 102, lift the positioning cap 202 upwards to release the locking structure 2. Lay moist filter paper in the storage slot of the storage tray 4, and place the seeds evenly on the filter paper, ensuring that the spacing between each seed is appropriate and avoiding overlap. Depending on the seed type, such as watermelon seeds, the illumination temperature and light cycle of the temperature control lamp can be set via an external controller.

[0020] Start the water pump and adjust the spray volume of the spray sleeve 5 to ensure that excess water can be discharged in time through the drain hole 401 at the bottom of the storage tank. After calibrating the camera 6 angle, close and lock the rotating door 102, start the camera 6, observe the image on the storage disk 4 through the external display terminal, and adjust the camera 6 angle until all seeds are clearly visible with no blind spots. Start the electric motor 301 to drive the rotating shaft 302 to rotate at a speed of five revolutions per hour, so that the storage tray 4 receives light and spray evenly, ensuring a consistent seed growth environment. The water pump starts at a preset frequency and sprays water or nutrient solution into the storage tank through the spray sleeve 5. Excess water is discharged through the drain hole 401 to prevent water accumulation in the seeds. Camera 6 automatically takes a seed image periodically and records the germination status in real time through image recognition technology, generating germination rate data, such as pixel analysis of the radicle breaking through the seed coat. The control fan regulates the humidity inside the incubator 1. Operators can check the seed germination status at any time through the observation glass or external terminal without opening the incubator, thus avoiding environmental disturbance. Germination data is exported. After the seed germination rate stabilizes, the image sequence and germination rate curve recorded by camera 6 are exported through an external terminal. Combined with the environmental data of the temperature control lamp, the seed germination performance is analyzed. After the seeds have germinated, turn off the power, lift the positioning cap 202 upwards to unlock the rotating door 102, take out the storage tray 4, remove the bolts and separate the semi-circular tray, and clean the filter paper and seed residue in the storage tank. Wipe the inside of the incubator 1 and the observation glass with a soft cloth, check if the spray sleeve 5 is blocked, and disassemble and clean it if necessary; check the elasticity of the support spring, and replace it in time if it fails, and ensure that the locking structure 2 works normally.
