Description

A supplemental lighting device to promote the growth of plant tissue culture seedlings Technical Field

[0001] This utility model relates to the field of plant tissue culture seedling technology, and in particular to a supplemental lighting device for promoting the growth of plant tissue culture seedlings. Background Technology

[0002] Light is the direct energy source for plant photosynthesis. The light environment required by plants varies at different stages of their growth. A suitable light environment is crucial for plant growth and development. Different light qualities have significantly different biological effects, including plant morphogenesis and physiological effects. Studies have shown that plants mainly absorb red light (640-660nm) and blue-violet light (430-450nm) for photosynthesis. Currently, plant grow lights for tissue culture seedlings on the market are mainly used for large-area irradiation in greenhouses. There are no movable light boxes, and the existing plant grow lights have a simple structure that is difficult to adjust according to the actual cultivation conditions. Most devices adjust the height of the light source by manually raising and lowering the support or increasing or decreasing the length of the suspension chain, such as using bolts to fix the slide rail or snap-on positioning holes. This method is not only time-consuming (requiring tightening and loosening screws layer by layer), but also has low precision (adjustment error often reaches ±5cm or more). Therefore, it is necessary to propose an improvement scheme for existing plant grow lights to meet the actual needs of improving plant stress resistance and timber quality. Summary of the Invention

[0003] The purpose of this invention is to provide a supplementary lighting device for promoting the growth of plant tissue culture seedlings, thereby solving the problem that existing supplementary lighting devices are difficult to adjust according to the actual condition of the plant tissue culture seedlings.

[0004] To achieve the above objectives, a supplemental lighting device for promoting the growth of plant tissue culture seedlings is provided, comprising a base, columns fixedly connected to the four ends of the base, a support platform fixedly connected to the top of the columns, a turntable rotatably connected to the upper center of the support platform, a motor fixedly connected to the middle of the base and the support platform, and the output end of the motor fixedly connected to the turntable.

[0008] According to the aforementioned supplemental lighting device for promoting the growth of plant tissue culture seedlings, a light plate is fixedly connected to the rotating shaft, and a gear is fixedly connected to the outer end of the rotating shaft located on the rotating block.

[0009] According to the aforementioned supplemental lighting device for promoting the growth of plant tissue culture seedlings, a mounting frame is fixedly connected to one outer end of the movable plate, and a motor is fixedly connected to the inner end of the mounting frame.

[0010] According to the aforementioned supplemental lighting device for promoting the growth of plant tissue culture seedlings, the output end of the motor three is fixedly connected to a gear two, and the gear two meshes with the gear one.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Referring to Figures 1-4, an embodiment of this utility model provides a supplementary lighting device for promoting the growth of plant tissue culture seedlings. The device includes a base 4, with columns 2 fixedly connected to the four ends of the base 4. A support platform 1 is fixedly connected to the top of the columns 2. A turntable 9 is rotatably connected to the center of the support platform 1. A motor 3 is fixedly connected to the center of the base 4 and the support platform 1. The output end of the motor 3 is fixedly connected to the turntable 9. The columns 2 support the device, and the motor 3, when started, drives the turntable 9 to rotate, thereby adjusting the angle of the supplementary lighting component to ensure that the supplementary lighting component can provide supplementary lighting to plant groups in different positions.

[0026] A connecting frame 8 is fixedly connected to the four ends of the top of the turntable 9. A motor 7 is fixedly connected to the upper end of the connecting frame 8. A lead screw 12 is rotatably connected to the lower middle part of the connecting frame 8, and the other end of the lead screw 12 is rotatably connected to the turntable 9. A movable plate 13 is threadedly connected to the lead screw 12. Starting the motor 7 can drive the lead screw 12 to rotate. Under the action of the threaded connection, the movable plate 13 can be raised and lowered to adjust the height of the supplementary lighting component.

[0027] A second motor 7 is fixedly connected to the upper center of the connecting frame 8. The output end of the second motor 7 is fixedly connected to the lead screw 12. Rotating blocks 14 are fixedly connected to both ends of the outer side of the movable plate 13. A rotating shaft 16 is rotatably connected to the inner end of the rotating block 14. By setting the rotating block 14 and the rotating shaft 16, the light plate 10 can be rotated inside it. The light plate 10 in this device uses LED plant growth lights, which can be customized in terms of spectrum (such as the ratio of red to blue light). It is energy-saving, efficient, and has a long lifespan. Blue light (430-450nm): promotes leaf growth; red light (640-660nm): promotes flowering and fruiting; full-spectrum white light: simulates natural light and is suitable for the entire growth cycle.

[0028] A light-emitting plate 10 is fixedly connected to a rotating shaft 16, and a gear 15 is fixedly connected to the outer end of the rotating block 14. A mounting bracket 17 is fixedly connected to one outer end of the movable plate 13, and a motor 18 is fixedly connected to the inner end of the mounting bracket 17. A gear 19 is fixedly connected to the output end of the motor 18. The gear 19 meshes with the gear 15. When the motor 18 is started, it drives the gear 19 to rotate. Under the meshing action, the rotating shaft 16 and the light-emitting plate 10 rotate, completing the pitch adjustment of the light-emitting plate 10, thereby adjusting its illumination range and improving its illumination. The applicability and convenience of the entire supplementary lighting device are enhanced by the fact that both motor 2 (7) and motor 3 (18) are equipped with spring-loaded electromagnetic brakes at their tails. When powered on, the electromagnetic coil generates magnetic force, which overcomes the spring pressure and releases the brake pad, allowing the motor shaft to rotate freely. When powered off, the spring force presses the brake pad against the friction disc, locking the motor shaft through friction to achieve a self-locking effect. This ensures the stability of the device's adjustment components during use. In addition, the motor itself has been treated to be waterproof and corrosion-resistant, ensuring its service life in outdoor environments. Motor 1 (3) is an AC induction motor, capable of driving heavy objects to rotate.

[0029] The lower ends of the connecting frame 8 are fixedly connected to the sliding rods 11, and the movable plate 13 is slidably connected to the sliding rods 11. The upper center of the turntable 9 is fixedly connected to the power box 6, and the four ends of the base 4 are equipped with casters 5. The sliding rods 11 can restrict the movable plate 13 to ensure the stability of the movable plate 13 during lifting and adjustment. At the same time, the power box 6 is equipped with a battery, which is electrically connected to the four sets of light panels 10 to supply power and improve its performance. In actual use, solar panels can also be installed on the top to improve its battery life.

[0030] Working principle: In use, the operator moves the entire supplemental lighting device to the cultivation shed where the plant tissue culture seedlings are growing using the casters 5. Then, the casters 5 are self-locked. The supplemental lighting components are adjusted according to the required range and angle of supplemental lighting. First, the motor 1 3 is started to drive the turntable 9 to rotate, which in turn drives the supplemental lighting components to rotate, ensuring that the supplemental lighting components correspond to the planting area of ​​the plant tissue culture seedlings. Then, the motor 2 7 is started to drive the lead screw 12 to rotate. Under the action of the threaded connection, the movable plate 13 can drive the supplemental lighting components to adjust their height to suit the supplemental lighting of plant tissue culture seedlings of different heights. Finally, the motor 3 18 is started to drive the gear 2 19 to rotate. Under the meshing action, the rotating shaft 16 and the light plate 10 are rotated to complete the pitch adjustment of the light plate 10, thereby adjusting its lighting range and improving the applicability and convenience of the entire supplemental lighting device.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
