Description

Technical Field

[0001] This utility model relates to the field of rice seedling testing technology, and in particular to a laboratory rice seedling testing device. Background Technology

[0002] In the cutting-edge field of modern agricultural biotechnology, in-depth research into the effects of laser irradiation on rice gene expression has become a key research direction for cultivating superior rice varieties and significantly improving rice yield and quality, possessing extremely important theoretical and practical significance. Lasers, as a radiation source with high energy density, have the significant advantage of precisely controlling wavelength, intensity, and irradiation time. By carefully designing combinations of different parameters, lasers can precisely induce specific changes in rice genes. This precise gene regulation method opens a new door for rice genetic breeding research, providing researchers with an innovative path to explore the mysteries of rice genetics and cultivate rice varieties with superior traits.

[0003] However, the laser irradiation angle of existing laboratory rice seedling testing devices is generally relatively fixed, making it difficult to create complex and variable lighting environments. During the natural growth process of rice, the light it receives is constantly changing in both direction and intensity. Fixed laser irradiation modes cannot realistically simulate this natural lighting condition, resulting in deviations between experimental results and actual conditions. At the same time, the disassembly and replacement of the existing device's light module is complicated, which not only consumes time and effort but also limits the flexibility and efficiency of the experiment, making it impossible to quickly respond to diverse experimental needs and seriously affecting the smooth progress of rice seedling testing research. Utility Model Content

[0004] The existing laboratory rice seedling testing devices generally have a relatively fixed laser irradiation angle, making it difficult to create a complex and variable lighting environment. During the natural growth process of rice, the light it receives is constantly changing in both direction and intensity. A fixed laser irradiation mode cannot realistically simulate this natural lighting condition, resulting in deviations between experimental results and actual conditions. This invention provides a laboratory rice seedling testing device with the advantages of easy adjustment of the design angle and quick replacement of the lighting module, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a laboratory rice seedling testing device, including an experimental box, with slots on the inner wall of the experimental box, and a placement rack inside the experimental box. The two sides of the placement rack are inserted into the slots. Four rotary motors are installed at the four corners of the upper end of the experimental box. The output ends of the rotary motors pass through the experimental box and are connected to a rotating plate. A bracket is provided at the bottom of the rotating plate. A light module is installed on the inner side of the bracket. Support rods are provided on both sides of the light module and are rotatably installed on the inner side of the bracket. A worm gear is provided on the side of the bracket. The support rods pass through the side of the bracket and are fixedly connected to the worm gear. Two support plates are fixedly installed on the side of the bracket. A drive motor is installed on the outside of the support plate. The output end of the drive motor passes through the support plate and is connected to a worm. The bottom of the worm meshes with the upper end of the worm gear.

[0006] Preferably, the bottom of the rotating plate is fixedly connected to two fixing blocks, and the surfaces of the two fixing blocks are provided with limit holes. A connecting seat is fixedly installed at the upper end of the bracket.

[0007] By setting limit holes on the fixing block, a positioning and locking basis is provided for the connection between the bracket and the rotating plate, ensuring a stable connection between the two.

[0008] Preferably, the connecting seat is internally threaded with a screw, and the inner side of the screw is rotatably connected with a conical movable block. The two sides of the conical movable block are provided with mating blocks, and the inner sides of the two mating blocks are provided with sliding grooves.

[0009] By setting the internal screw of the connecting seat, the conical movable block is driven to move, thereby controlling the action of the mating block and realizing the connection or separation of the bracket and the rotating plate.

[0010] Preferably, both sides of the conical movable block are fixedly connected to sliders, which are slidably installed inside the groove.

[0011] By setting sliders on both sides of the conical movable block, the linear motion of the conical movable block is accurately converted into the lateral sliding of the mating block, ensuring the stable transmission of the structure.

[0012] Preferably, a positioning rod is fixedly installed on the side of the mating block, one end of the positioning rod passes through the connecting seat and is located inside the limiting hole. A return spring is fixedly installed on one side of each mating block, and the other side of the return spring is fixedly installed on the inner wall of the connecting seat. A slide rail is provided in the inner wall of the connecting seat, and the two mating blocks are slidably connected inside the slide rail.

[0013] By setting the positioning rod on the side of the mating block, it can cooperate with the upper limit hole of the fixed block to achieve the effect of quick positioning and locking of the bracket and the rotating plate.

[0014] Preferably, the inner side of the placement rack is equipped with a partition baffle, the bottom of the placement rack is provided with a central mesh, and the bottom of the experimental box has two ventilation slots, with a fan fixedly installed on the inner side of the ventilation slots.

[0015] By setting up partitions on the inside of the rack, different rice seedling samples or seedlings at different growth stages can be separated, which facilitates classification management and observation and recording.

[0016] This utility model has the following advantages:

[0017] 1. By installing rotary motors at the four corners of the upper part of the experimental chamber, the rotating plate can be rotated in multiple directions. A light module is installed on the bracket at the bottom of the rotating plate. The worm gear and worm on the side of the bracket cooperate. When the drive motor is turned on, it drives the worm to rotate, and the worm drives the worm wheel to rotate. Since the worm wheel is fixedly connected to the support rod of the light module, the light module can rotate accordingly, realizing multi-angle adjustment. This device can simulate the dynamic changes of light direction in the natural environment, providing rice seedlings with more natural lighting conditions, improving the accuracy and reliability of experimental results, and providing more comprehensive data support for rice gene expression research.

[0018] 2. By creating a limiting hole in the fixed block, when the internal screw of the connecting seat is rotated, the conical movable block moves under the action of the screw, while the sliders on both sides slide in the groove of the mating block. Since the conical movable block and the inclined surfaces of the two mating blocks are tangent, it drives the mating blocks to slide to both sides. The positioning rod on the side of the mating block moves accordingly and connects to the inside of the limiting hole, thereby locking the bracket at the bottom of the rotating plate. When the screw is reversed, the two mating blocks, through the rebound effect of the return spring, cause the positioning rod to disengage from the limiting hole, so that the bracket and the light module can be disassembled as a whole. This facilitates the replacement of different types of light modules, meets the diverse needs of different experiments for parameters such as light intensity and spectrum, and improves the flexibility and scalability of the experiment.

[0024] 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.

[0025] Please see Figures 1-3 A laboratory rice seedling testing device includes an experimental box 1. The inner wall of the experimental box 1 has slots 2. The experimental box 1 has switchable glass panels installed at both ends. The experimental box 1 has a placement rack 3 inside. The two sides of the placement rack 3 are inserted into the slots 2, which allows the experimenter to observe the growth of rice seedlings in the box at any time and can maintain the stability of the environment inside the box to a certain extent, avoiding excessive interference from external factors. At the same time, the placement rack 3 is inserted into the slots 2 on both sides, which facilitates the installation and removal of the placement rack 3, and makes it easy to replace, maintain and adjust the placement rack 3 and seedlings, improving the convenience of experimental operation. Four rotary motors 8 are installed at the four corners of the upper end of the experimental box 1. The output end of the rotary motor 8 passes through the experimental box 1 and is connected to a rotating plate 9. The bottom of the rotating plate 9 is provided with a bracket 10. The inner side of the bracket 10 is equipped with a light module 11. By installing the rotary motors 8 at the four corners of the upper end of the experimental box 1, the rotating plate 9 can be rotated by the rotary motors 8, realizing multi-directional adjustment of the rotating plate 9, enhancing the adaptability of the device.

[0026] The light module 11 is mounted on two sides with support rods and rotatably inside the bracket 10. A worm gear 23 is located on the side of the bracket 10. The support rods pass through the side of the bracket 10 and are fixedly connected to the worm gear 23. Two support plates 24 are fixedly mounted on the side of the bracket 10. A drive motor 25 is mounted on the outside of the support plates 24. The output end of the drive motor 25 passes through the support plates 24 and is connected to a worm 26. The bottom of the worm 26 meshes with the upper end of the worm gear 23. The light module 11 is mounted on the bracket 10 at the bottom of the rotating plate 9. The worm gear 23 on the side of the bracket 10 cooperates with the worm 26. When the drive motor 25 is turned on, it drives the worm 26 to rotate, which in turn drives the worm gear 23 to rotate. Since the worm gear 23 is fixedly connected to the support rods of the light module 11, the light module 11 can rotate accordingly, achieving multi-angle adjustment. This allows the device to simulate the dynamic changes in the direction of light in the natural environment, providing rice seedlings with more natural lighting conditions, improving the accuracy and reliability of experimental results, and providing more comprehensive data support for rice gene expression research.

[0027] Please see Figures 2-4 Two fixed blocks 12 are fixedly connected to the bottom of the rotating plate 9. Limiting holes 13 are formed on the surface of each fixed block 12. A connecting seat 14 is fixedly installed at the upper end of the bracket 10. A screw 15 is threadedly connected to the inside of the connecting seat 14. A conical movable block 16 is rotatably connected to the inner side of the screw 15. Fitting blocks 17 are provided on both sides of the conical movable block 16. By opening the limiting holes 13 in the fixed blocks 12, when the screw 15 inside the connecting seat 14 is rotated, the conical movable block 16 moves under the action of the screw 15. Simultaneously, the sliders 19 on both sides slide within the grooves 18 of the fitting blocks 17. Because the conical movable block 16 is tangent to the inclined surfaces of the two fitting blocks 17, it causes the fitting blocks 17 to slide to both sides. Grooves 18 are formed on the inner sides of each of the two fitting blocks 17. Slider 19 is fixedly connected to both sides of the conical movable block 16 and slidably mounted on the sliding blocks 17. Inside the groove 18, the linear movement of the conical movable block 16 can be precisely converted into the lateral sliding of the mating block 17. A positioning rod 21 is fixedly installed on the side of the mating block 17. One end of the positioning rod 21 passes through the connecting seat 14 and is located inside the limiting hole 13. When the conical movable block 16 moves closer to the two mating blocks 17, the mating blocks 17 are squeezed and moved, causing the positioning rod 21 on its side to move accordingly and connect to the inside of the limiting hole 13, thereby locking the bracket 10 at the bottom of the rotating plate 9. When the screw 15 is reversed, the two mating blocks 17, through the rebound effect of the return spring 20, cause the positioning rod 21 to disengage from the limiting hole 13, so that the bracket 10 and the light module 11 can be disassembled as a whole, making it convenient to replace different types of light modules 11, meeting the diverse needs of different experiments for light intensity, spectrum and other parameters, and improving the flexibility and scalability of the experiment.

[0028] A return spring 20 is fixedly installed on one side of each mating block 17, and the other side of the return spring 20 is fixedly installed on the inner wall of the connecting seat 14. By installing return springs 20 on both sides of the mating block 17, when the screw 15 is rotated in the opposite direction, the return spring 20 can automatically cause the mating block 17 to spring back, allowing the positioning rod 21 to disengage from the limiting hole 13, thereby realizing the quick disassembly of the bracket 10 and the light module 11, simplifying the operation process of replacing the light module 11, and improving experimental efficiency. A slide rail 22 is provided in the inner wall of the connecting seat 14, and the two mating blocks 17 are slidably connected inside the slide rail 22. By setting the slide rail 22 to limit the two mating blocks 17, the stability of the mating blocks 17 during horizontal movement is ensured, and the positioning rod 21 can be accurately connected inside the limiting hole 13.

[0029] A partition 4 is installed on the inner side of the placement rack 3. By installing the partition 4 on the inner side of the placement rack 3, different rice seedling samples can be isolated to prevent mutual interference and facilitate comparative experimental observation. A central mesh 5 is provided at the bottom of the placement rack 3, and two ventilation slots 6 are opened at the bottom of the experimental box 1. A fan 7 is fixedly installed on the inner side of the ventilation slots 6. The central mesh 5 at the bottom of the placement rack 3, together with the ventilation slots 6 and the fan 7 at the bottom of the experimental box 1, can promote air circulation, create a good ventilation environment for rice seedlings, which is conducive to their healthy growth and improves the accuracy of the experiment.

[0030] Working principle: In actual use, first place the rice seedlings on the placement rack 3 inside the experimental box 1. The placement rack 3 is installed and fixed by inserting the slots 2 on both sides into the inner wall of the experimental box 1. The net 5 can provide support for the seedlings and ensure good ventilation. Start the fan 7 to promote the circulation of air in the experimental box 1 and regulate the temperature and humidity inside the box. When it is necessary to adjust the light angle, start the rotary motor 8 at the four corners of the upper end of the experimental box 1. The output end of the rotary motor 8 drives the rotating plate 9 to rotate, thereby changing the overall direction of the bottom support 10 and the light module 11 of the rotating plate 9.

[0031] Next, the drive motor 25 on the side support plate 24 of the bracket 10 is started to drive the worm gear 26 to rotate, and the worm wheel 23 rotates accordingly. Since the worm wheel 23 is fixedly connected to the support rods on both sides of the light module 11, the light module 11 can be finely adjusted at multiple angles to simulate the dynamic changes in the direction of light in the natural environment.

[0032] During the experiment, if it is necessary to replace different types of light modules 11, rotate the screw 15 inside the connecting seat 14. At this time, the conical movable block 16 moves under the action of the screw 15, and the sliders 19 on both sides slide in the grooves 18 of the mating block 17. Because the conical movable block 16 and the inclined surfaces of the two mating blocks 17 are tangent, the mating blocks 17 will slide horizontally. The positioning rod 21 on the side of the mating block 17 moves accordingly. When the positioning rod 21 disengages from the limiting hole 13 on the bottom fixing block 12 of the rotating plate 9, the bracket 10 and the light module 11 can be disassembled as a whole for replacement. During installation, when the screw 15 is rotated to drive the conical movable block 16 to move towards the two mating blocks 17, the two mating blocks 17 are squeezed to move to both sides, so that the positioning rod 21 is reconnected inside the limiting hole 13 to achieve locking.
