Description

TECHNICAL FIELD

[0001] The application relates to the technical field of seedling cultivation, in particular to a seedling cultivation light supplementing structure. BACKGROUND

[0002] In the process of seedling cultivation, light is one of the key factors affecting the growth and development of seedlings. Especially in seasons and environments with insufficient light or short light time, light supplementing measures are crucial to ensure the normal growth of seedlings.

[0003] However, the traditional seedling cultivation light supplementing device usually adopts fixedly installed lamps, the light supplementing angle and range of which are difficult to adjust, resulting in that part of the seedlings cannot obtain sufficient light, while part of the areas may appear over-bright or under-bright conditions, and the light uniformity is poor. This not only affects the photosynthesis efficiency of the seedlings and reduces the growth speed and quality of the seedlings, but also may cause uneven development of the seedling morphology and appear adverse phenomena such as overgrowth and thinness. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the problems of the traditional seedling cultivation light supplementing device, such as fixation, difficult adjustment of light supplementing angle and range, influence on growth quality and morphology development of seedlings and poor light uniformity, the application provides a seedling cultivation light supplementing structure.

[0005] The seedling cultivation light supplementing structure provided by the application adopts the following technical scheme:

[0006] A seedling cultivation light supplementing structure comprises a swing lamp group, a plurality of supports are equidistantly arranged on the swing lamp group, the swing lamp group comprises a plurality of main rods rotationally arranged on the supports, a plurality of light supplementing lamps are arranged on the main rods, the light supplementing lamps on adjacent main rods are staggered, one of the supports is provided with a driving assembly, the driving assembly comprises a gear arranged on the main rod, a reciprocating driving unit is arranged on the support and used for driving the gear to reciprocate, and a transmission unit is arranged between two adjacent gears.

[0007] Preferably, a branch rod is arranged on the main rod, and the light supplementing lamp is arranged at the end of the light supplementing lamp.

[0008] Preferably, the reciprocating driving unit comprises a rack engaged with the gear, and the rack can make linear reciprocating motion along the tangent direction of the pitch circle of the gear.

[0009] Preferably, the reciprocating driving unit further comprises a speed reducer arranged on the support, an output end of the speed reducer is connected with a swing rod, the end of the swing rod is hingedly connected with a connecting rod, and the connecting rod is hingedly connected with the rack.

[0010] Preferably, the transmission unit adopts a gear transmission structure.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] By using the swing light assembly and drive components together, the swing arm is driven to rotate at low speed by a geared motor, which in turn drives the connecting rod to pull the rack to move back and forth. This causes the gear to rotate back and forth at a fixed angle, which in turn causes the main rod and support rod to rotate. This changes the fill light angle and position, allowing the fill light to swing and fill light, expanding the fill light range while ensuring the uniformity of the fill light. Compared with existing technologies, this technology allows for adjustment of the fill light angle and range, ensuring the uniformity of the fill light effect. Attached Figure Description

[0017] The following is in conjunction with the appendix Figs. 1-3 This application will be described in further detail.

[0018] This application discloses a supplemental lighting structure for seedling cultivation. (Refer to...) Figs. 1-3 A seedling cultivation supplementary lighting structure mainly consists of a support frame 1, a swing lamp group 2, and a drive component 3, which provides efficient and uniform supplementary lighting for seedling cultivation and meets the light requirements for seedling growth.

[0019] Reference Figs. 1-3 The support frame 1, serving as the structural framework for the entire supplemental lighting structure, is made of high-strength aluminum alloy. Its structural design can be flexibly customized according to actual usage scenarios, such as rectangular frames or arched structures, to ensure stable installation and good light coverage in different planting layouts. The components of the support frame 1 are connected by welding or bolts, and the connection points are reinforced to form a robust overall structure with sufficient strength and rigidity to withstand the weight of the supplemental light lamp 203 and external forces such as wind loads and vibrations in the outdoor environment. This effectively prevents the supplemental lighting effect from being affected by structural deformation or damage, providing a reliable foundation for the long-term stable operation of the supplemental lighting structure.

[0020] Reference Fig. 2 The two main poles 201 of the swing light assembly 2 are made of stainless steel and connected to the bracket 1 via bearings. This connection method allows the main poles 201 to rotate flexibly on the bracket 1, greatly reducing rotational resistance and wear, ensuring the smoothness and stability of the swing of the supplemental light 203, extending the service life of the equipment, and also reducing energy consumption. The support pole 202 is connected to the main poles 201 by welding or a detachable threaded connection. The welding connection ensures the structural robustness, while the threaded connection provides convenience for adjusting the angle and position of the support pole 202 when needed. This allows the supplemental light 203 to be flexibly adjusted according to the growth height and distribution of the seedlings, improving the adaptability and versatility of the supplemental lighting structure and ensuring that light accurately covers each seedling. The supplemental light 203 uses full-spectrum LED lamps, which have high luminous efficiency, low energy consumption, long lifespan, and can provide a spectral distribution similar to natural sunlight, making them very suitable for the photosynthetic needs of seedlings. The supplemental light 203 and the support rod 202 are connected by a sturdy and reliable fixing method such as clips and brackets, which effectively prevents the supplemental light 203 from loosening or falling during the swinging process, ensuring the safe and stable operation of the supplemental lighting and providing continuous and stable light conditions for the growth of seedlings.

[0021] Reference Fig. 1 and Fig. 3The geared motor 3011 of the drive assembly 3 serves as the power source. It is selected for its stable speed, high torque output, and good reliability, with a speed range of 3-30 rpm. This precisely meets the swaying frequency requirements of the supplementary lighting lamp 203, ensuring uniform light distribution. The geared motor 3011 is securely mounted on the bracket 1 using vibration-damping pads or bolts, effectively reducing the impact of vibrations generated during motor operation on the entire supplementary lighting structure. This avoids problems such as component loosening, accelerated wear, and unstable lighting caused by vibration, ensuring stable operation of the supplementary lighting structure and consistent lighting effects. The swing arm 3012 is made of high-strength alloy steel. Its length and shape are optimized based on the output shaft position of the geared motor 3011 and the motion trajectory of the rack 3014. During the rotation of the swing arm 3012, it can smoothly and effectively pull the connecting rod 3013 and the rack 3014, achieving stable force transmission and ensuring the efficient operation of the drive assembly 3. Both connecting rod 3013 and rack 3014 are made of high-strength alloy steel. The connection parts are precision machined and heat-treated, possessing high-strength connection and good wear resistance. This ensures that there will be no breakage, deformation, or severe wear during long-term reciprocating motion, guaranteeing the reliability and stability of power transmission. The rack 3014 and gear 302 adopt a high-precision meshing design, with precise matching of tooth profile and module, ensuring smooth transmission without jamming or noise. This allows gear 302 to accurately reciprocate within a fixed angle range under the drive of rack 3014, thereby driving the main rod 201 and support rod 202 to achieve precise oscillation, improving the operating accuracy and reliability of the supplementary lighting structure.

[0022] The gear transmission structure of the transmission unit 303 is designed according to the distance and transmission ratio requirements between adjacent gears 302. This allows the two main rods 201 to rotate synchronously, ensuring coordinated and consistent supplementary lighting action of the entire swing light group 2, expanding the supplementary lighting range, and, due to the swinging motion of the supplementary lights 203, the light can be more evenly distributed on the seedlings, providing better lighting conditions for their growth. The installation between the gears uses high-precision bearings and bushings, ensuring the concentricity and axial positioning accuracy of the gears, effectively reducing energy loss and wear during transmission, extending the service life of the transmission unit 303, reducing equipment maintenance costs, and improving the overall performance and reliability of the supplementary lighting structure.

[0023] The implementation principle of the seedling cultivation supplementary lighting structure in this application embodiment is as follows:

[0024] At the seedling cultivation site, the bracket 1 of this supplementary lighting structure is installed in a suitable position according to the planting layout and growth needs of the seedlings, such as the top lifting frame of the greenhouse, the side of the planting frame, etc., to ensure that the bracket 1 is firmly fixed and will not be displaced or shaken due to wind, vibration or other factors.

[0025] When supplemental lighting is needed for the seedlings, the operator connects the power supply and starts the geared motor 3011. The geared motor 3011 operates stably at a low speed, and its output shaft drives the swing arm 3012 to rotate around a fixed axis. The end of the swing arm 3012 is hinged to the connecting rod 3013. As the swing arm 3012 rotates, the other end of the connecting rod 3013 pulls the rack 3014 to move back and forth along a predetermined linear track. The rack 3014 meshes tightly with the gear 302, and the reciprocating linear motion of the rack 3014 is converted into the reciprocating rotation of the gear 302.

[0026] Gear 302 is fixedly installed at one end of the main rod 201. When gear 302 rotates, the main rod 201 also rotates around its connection point with the bracket 1. The support rod 202 on the main rod 201 and the supplementary light 203 installed at the end of the support rod 202 will also change position and angle with the rotation of the main rod 201, thereby achieving the swaying supplementary lighting effect of the supplementary light 203.

[0027] Adjacent gears 302 are connected by a gear transmission structure in a transmission unit 303. The gear ratio and transmission method of the transmission unit 303 are carefully designed to ensure that when one gear 302 rotates, the adjacent gear 302 can rotate synchronously through the transmission unit 303, and the rotation angle and speed remain consistent. In this way, all the supplementary lights 203 in the entire swing light group 2 can swing and supplement light in a coordinated manner, avoiding the problem of uneven lighting caused by inconsistent operation of individual supplementary lights.

[0028] During the supplemental lighting process, operators can control the swing frequency and amplitude of the supplemental light 203 by adjusting the speed and running time of the geared motor 3011 according to the growth stage, variety characteristics, and actual light conditions of the seedlings. This allows for precise adjustment of the supplemental lighting angle, range, and uniformity, meeting the supplemental lighting needs of different seedlings, improving the supplemental lighting effect, and promoting the healthy and rapid growth of the seedlings.
