Description

Technical Field

[0001] This utility model relates to the field of vegetable planting technology, specifically a seedling cultivation rack for vegetable planting. Background Technology

[0002] With global population growth and the continuous increase in residents' demand for fresh vegetables, the vegetable planting industry faces the dual tasks of ensuring yield and optimizing quality. Against the backdrop of increasingly scarce arable land resources and the urgent need to improve land use efficiency, traditional planar seedling raising models are no longer sufficient to meet the demands of large-scale, intensive planting. The industry's demand for efficient space utilization is becoming increasingly urgent. Furthermore, as a crucial initial step in vegetable planting, the stability of the seedling environment (such as temperature, humidity, light, and nutrient supply) directly affects seedling survival rates and subsequent growth. The rapid development of facility agriculture technology provides technical support for precise control of the seedling environment. Against this backdrop, seedling cultivation racks for vegetable planting have emerged. Based on a multi-layered, three-dimensional structural design, they are adapted to the spatial layout of modern greenhouses and polytunnels, expanding seedling space within limited land areas. They also facilitate the integration of intelligent temperature control, fertigation, and other technologies to create stable and suitable growth conditions for vegetable seedlings, aligning with the "high efficiency, high quality, and intensive" development direction in the process of agricultural modernization. They have become an important facility carrier connecting the vegetable seedling raising stage with large-scale planting.

[0003] Traditional vegetable seedling cultivation racks are commonly used in home gardens, small planting bases, and seedling factories due to their simple structure and low cost. However, they have significant problems. The spacing between the upper and lower layers is a fixed size that cannot be adjusted, which limits the planting range. Frequent replacement of different equipment for corresponding seedling cultivation greatly restricts their flexibility of use and applicable scenarios.

[0017] 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.

[0018] Please see Figures 1-4 A seedling cultivation rack for vegetable planting, comprising: Cultivation structure 1 is a frame assembled from stainless steel profiles; The cultivation structure 1 includes a movable base frame 11, which is a H-shaped profile frame with four legs welded to the four corners of its lower surface. Each leg is equipped with a caster wheel with a brake. A sliding column 12 is rigidly connected to each of the four corners of the upper frame of the movable base frame 11. These sliding columns 12 are connected to the seedling frame 14 via sliding locking sleeves 141 integrated with the four corners of the seedling frame 14, allowing for adjustable height. The sliding locking sleeves 141 have screw holes on their surface, which are threaded into bolts. These bolts position the adjusted seedling frame 14 at different heights on the sliding columns 12. A prefabricated seedling box can be embedded within each frame of the seedling frame 14. The surface of the sliding column 12 corresponds to... The bolts are evenly pre-set with multiple holes and slots for auxiliary positioning. The upper ends of these sliding columns 12 are rigidly connected to the mounting top plate 13. The lower surface of the mounting top plate 13 is evenly pre-set with multiple screw holes corresponding to the seedling frame 14 where the seedlings are placed. The screw holes are used to assemble with multiple supporting poles 15 with screws at the top. The lower ends of the supporting poles 15 extend beyond the seedling frame 14 and are flush with the upper frame of the movable base 11. Each supporting pole 15 corresponds to a single plant. The interior of the sliding column 12 has a rectangular open groove recessed towards the center of the seedling frame 14. A strip light 16 is installed and positioned inside the open groove. The strip light 16 is connected to an external power module via a circuit. At least one seedling frame 14 is provided that slides on the sliding column 12.

[0019] During operation, the seedling cultivation frame is first moved to a suitable environment such as a greenhouse or shed by using the universal casters with brakes on the lower surface of the movable base frame 11. Once in place, the universal casters are locked in place. Then, according to the characteristics of the seedling variety or the growth stage, the bolts on the surface of the four corner sliding lock sleeves 141 of the seedling frame 14 are loosened, allowing the seedling frame 14 to slide up and down along the sliding column 12 to a suitable height via the sliding lock sleeves 141. Subsequently, the bolts are screwed through the screw holes of the sliding lock sleeves 141 and into the corresponding preset slots on the surface of the sliding column 12 to complete the positioning. Multiple seedling frames 14 are adjusted separately to reserve sufficient space for light and ventilation, while simultaneously achieving layered distribution of the strip light 16. To save energy, the supporting poles 15 are then threaded onto the corresponding areas of the screw holes on the lower surface of the mounting plate 13 via upper screws, according to the seedling planting spacing. This ensures that the lower end of the supporting poles 15 passes over the seedling frame 14 and the supporting seedling box and is flush with the upper frame of the movable base frame 11. Each supporting pole 15 is precisely aligned with a single seedling to prevent it from falling over. The seedlings are then planted in the supporting seedling box. During seedling cultivation, an external power source is connected to power on the strip light strips 16 installed in the open slots of the sliding column 12, providing uniform supplemental lighting for the seedlings in each layer. This provides suitable space, light, and support conditions for the seedlings, ensuring their efficient growth.

[0020] In summary, by using the sliding locking sleeves 141 integrally formed at the four corners of the seedling frame 14 to slide and engage with the sliding columns 12, and by providing screw holes in the sliding locking sleeves 141 and multiple sets of auxiliary positioning holes and slots on the surface of the sliding columns 12, the height of the seedling frame 14 on the sliding columns 12 can be flexibly adjusted according to the characteristics of the vegetable seedlings. This provides sufficient light and ventilation space for the upper and lower layers of seedlings. At the same time, by adjusting the seedling frame 14, the strip light strips 16 and the supporting poles 15 can be distributed in layers. This not only rationally allocates growth space suitable for the characteristics of the vegetable seedlings, but also provides suitable light and support conditions for the vegetable seedlings, ensuring efficient growth of the vegetable seedlings and reducing the consumption of corresponding resources.

[0021] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0022] Working Principle: During operation, the entire seedling cultivation rack is first moved to a suitable environment for vegetable seedling cultivation, such as a greenhouse or polytunnel, by using the universal casters with brakes on the lower surface of the base frame 11. After being moved into place, the universal casters are locked to ensure the stability of the cultivation rack and prevent accidental movement from affecting seedling growth. Next, the height of the seedling frame 14 is adjusted according to the characteristics of the vegetable seedlings (such as expected growth height) or their current growth stage. During adjustment, the bolts on the four corner sliding lock sleeves 141 of the seedling frame 14 are first loosened, allowing the seedling frame 14 to slide up and down along the sliding column 12 via the sliding lock sleeves 141. When the frame slides to a height that meets the seedling growth space requirements, the bolts are passed through the screw holes of the sliding lock sleeves 141 and screwed into the corresponding preset slots on the surface of the sliding column 12, completing the height positioning of a single layer of the seedling frame 14. If multiple seedling frames 14 are provided, the height of each set of frames is adjusted in the same way to ensure sufficient light and ventilation space between the upper and lower frames, solving the problem of fixed spacing in traditional cultivation racks. At the same time, it also achieves layered distribution of the strip light 16, which is more conducive to saving energy. Then, according to the planting spacing of the seedlings in the seedling frame 14, the supporting poles 15 are threaded together with the screws at their upper ends and the corresponding screw holes on the lower surface of the mounting top plate 13. This ensures that the lower end of the supporting poles 15 passes over the seedling frame 14 and the supporting seedling box and is flush with the upper frame of the movable base frame 11. It also ensures that each supporting pole 15 accurately corresponds to a single seedling, providing support for the seedling growth and preventing the seedlings from falling over due to their slender stems. Then, the seedlings are planted in the seedling tray. During the seedling process, an external power module can be connected to power the strip light 16 installed in the open slot of the sliding column 12. The strip light 16 faces the center area of ​​the seedling frame 14 and can provide uniform supplemental light to the seedlings in each layer, meeting the light requirements of the seedlings for photosynthesis. During this process, by adjusting the seedling frame 14, the spatial environment suitable for the characteristics of the vegetable seedling varieties can be reasonably allocated, and sufficient light and support conditions can be provided for them.
