Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable cultivation technology, and in particular to a double-layer seedling rack for fruit and vegetable seedling cultivation. Background Technology

[0002] Seedling cultivation is a crucial initial step in melon and fruit planting. It refers to the process of cultivating melon and fruit seeds or branches into robust seedlings under suitable environmental conditions. First, select plump, disease-free, and high-quality seeds. After disinfection and soaking, sow them in seedbeds or nutrient pots. During this period, temperature, humidity, and light must be precisely controlled to create favorable conditions for seed germination and seedling growth. At the same time, apply fertilizer and water appropriately, and prevent and control diseases and pests in a timely manner to ensure the seedlings grow vigorously. Through scientific seedling cultivation, the survival rate and stress resistance of melon and fruit seedlings can be improved, laying a solid foundation for subsequent high-quality and high-yield production.

[0003] To create a suitable environment for the growth of melon and fruit seedlings and improve the efficiency and yield of seedling cultivation, the application of melon and fruit seedling beds is becoming increasingly widespread. Existing double-layer seedling racks for melon and fruit seedling cultivation are usually constructed from only a few support rods. Although they can provide some support, their overall stability is poor. In the event of severe weather, they may deform or even collapse, causing serious damage to the seedlings and affecting the yield of melon and fruit cultivation. Furthermore, although existing double-layer seedling racks can provide some protection, their structure is fixed and the connections between the support structures are not flexible enough, making it difficult to adjust them flexibly according to the needs of different growth stages of the seedlings.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1:

[0028] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a double-layer seedling rack for fruit and vegetable seedling cultivation, including a base 1. Multiple sets of greenhouse poles 2 are installed on the top of the base 1. A first shelf 3 and a second shelf 4 are respectively provided on the inner side of the greenhouse poles 2. Ventilation holes 5 are opened on the inner walls of the first shelf 3 and the second shelf 4. Fixing components 6 for fixing the first shelf 3 and the second shelf 4 are sleeved on the outer side of the greenhouse poles 2.

[0029] The base 1 provides stable support for the entire fruit and vegetable seedling cultivation bed, ensuring its stability under the weight of the fruit and vegetable plants, the storage boards, and external environmental influences. The greenhouse pole 2 is the main load-bearing and supporting component of the cultivation bed, used to build the overall frame of the cultivation bed. The first storage board 3 and the second storage board 4 are used to place the items needed for fruit and vegetable seedling cultivation, providing a support platform for the growth of fruit and vegetable seedlings. The ventilation holes 5 on their inner walls help air circulation, providing good ventilation conditions for the growth of fruit and vegetable seedlings and avoiding problems such as excessive humidity and bacterial growth caused by poor air circulation. The fixing component 6 can fix the first storage board 3 and the second storage board 4 to the greenhouse pole 2 through its internal structure.

[0030] The top of the first shelf 3 is fixed with multiple sets of first connecting seats 7. The inner wall of the first connecting seat 7 is rotatably connected with a first pull rod 8. The outer side of the first pull rod 8 is fitted with a first sleeve rod 9, and the inner wall of the first sleeve rod 9 is slidably connected with a connecting rod. The outer side of the greenhouse rod 2 is fitted with a snap-fit ​​component 10.

[0031] The first connecting seat 7 is provided as a rotation connection point for the first pull rod 8, allowing the first pull rod 8 to rotate relative to the first shelf 3 and achieve a certain angle adjustment. The first pull rod 8 is used to adjust the height or angle of the shelf to meet the needs of different fruit and vegetable seedlings. The first sleeve rod 9 adjusts its length by sliding, assisting the first pull rod 8 in achieving support and adjustment functions, enhancing the stability and flexibility of the structure. The snap-fit ​​component 10 can fix the connecting rod slidably connected to the inner wall of the first sleeve rod 9 to the outside of the greenhouse rod 2 through its internal structure, thereby providing tension to the first shelf 3. It should be noted that both ends of the first sleeve rod 9 are fixed with threaded joints. The outer side of the threaded joint is threaded with a nut, and the inner wall of the threaded joint is provided with a snap-fit ​​groove. By tightening the nut, the threaded joint can be driven to retract along the snap-fit ​​groove, thereby fixing the first pull rod 8 to the connecting rod. This structure can adjust the height of the first shelf 3 and the second shelf 4 to adapt to different fruit and vegetable seedlings.

[0032] The snap-fit ​​assembly 10 includes a limiting seat 101 sleeved on the outside of the greenhouse rod 2, and the bottom of the limiting seat 101 is fixedly connected to the top of the connecting rod. A clamping block 102 is rotatably connected to the outside of the limiting seat 101, and a fixing bolt 103 is provided between the clamping block 102 and the inner wall of the limiting seat 101.

[0033] The limiting seat 101 is provided to provide an installation base for the clamping block 102. The clamping block 102 and the limiting seat 101 cooperate to clamp the greenhouse rod 2, which plays a role in fixing and limiting. The fixing bolt 103 is used to fix the relative position of the clamping block 102 and the limiting seat 101, ensuring that the snap-fit ​​assembly 10 can fix the connecting rod slidably connected to the inner wall of the first set of rods 9 onto the greenhouse rod 2.

[0034] Example 2:

[0035] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, the fixing component 6 includes two sets of first locking blocks 61 sleeved on the outside of the greenhouse pole 2, and one side of the two sets of first locking blocks 61 is fixedly connected to one side of the first shelf 3 and the second shelf 4 respectively. The outer side of the first locking block 61 is rotatably connected to the second locking block 62. The inner wall of the second locking block 62 is threaded with a screw 63, and one end of the screw 63 is rotatably connected to the inner wall of the first locking block 61.

[0037] The first locking block 61 and the second locking block 62 are connected by rotation, and together with the screw 63, the first shelf 3 and the second shelf 4 can be fixed on the greenhouse pole 2 to ensure that the shelf is stable and will not shake.

[0038] Specifically, a sleeve 11 for installing the greenhouse pole 2 is fixed on the top of the base 1, and a groove is provided on the inner wall of the sleeve 11, and a first clamp 12 is fitted on the outer side of the sleeve 11.

[0039] The sleeve 11 is used in conjunction with the first clamp 12 to facilitate the installation of the greenhouse pole 2, prevent the greenhouse pole 2 from loosening or falling off, improve the structural stability of the entire cultivation bed, and facilitate the disassembly of the greenhouse pole 2.

[0040] Specifically, the outer side of the greenhouse pole 2 is fixed with a drainage ditch bottom plate 13 and a locking block 14 by an installation ring, and there are two sets of locking blocks 14. The inner walls of the two sets of locking blocks 14 are respectively connected to the first locking groove 15 and the second locking groove 16.

[0041] The drainage ditch bottom plate 13 is set to collect and guide rainwater or irrigation water on the cultivation bed to prevent water accumulation from adversely affecting the melon and fruit seedlings. The locking block 14 is set to facilitate the installation of the first locking slot 15 and the second locking slot 16. The first locking slot 15 and the second locking slot 16 are used to fix the drainage ditch plastic film and the greenhouse film respectively.

[0042] Example 3:

[0043] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0044] Specifically, multiple sets of greenhouse poles 2 are connected by connecting pipes with diagonal bracing 17, and longitudinal poles 18 are provided on the outside of the greenhouse poles 2. A second clamp 19 for installing the longitudinal poles 18 is fitted on the outside of the greenhouse poles 2.

[0045] The installation of the diagonal brace 17 enhances the lateral stability between the greenhouse poles 2, improves the wind resistance and deformation resistance of the entire cultivation bed, and makes the cultivation bed structure more stable. The installation of the longitudinal pole 18 is used to further enhance the longitudinal structural strength of the cultivation bed, and together with the greenhouse poles 2 and the diagonal brace 17, it forms a stable frame structure, providing reliable support for melon and fruit seedling cultivation. The installation of the second clamp 19 is used to firmly fix the longitudinal pole 18 to the greenhouse pole 2, ensuring the stability of the longitudinal pole 18 position and playing a role in enhancing the structural strength.

[0046] Specifically, the bottom of the first shelf 3 and the top of the second shelf 4 are both fixed with second connecting seats 20, and the two sets of second connecting seats 20 are designed symmetrically.

[0047] The two sets of second connecting seats 20 are provided to provide a rotational connection point for the second tie rod 21.

[0048] Specifically, the inner walls of both sets of second connecting seats 20 are rotatably connected to second pull rods 21, and second sleeve rods 22 are sleeved on the outer side of the second pull rods 21.

[0049] The second tie rod 21 is used to enhance the connection stability between the first shelf 3 and the second shelf 4 or to adjust the relative position of the shelf to meet the needs of different fruit and vegetable seedling layouts. The second sleeve rod 22, by adjusting its length, can assist the second tie rod 21 in achieving support and adjustment functions, thereby enhancing the stability and flexibility of the structure. It should be noted that the functions of the second tie rod 21 and the second sleeve rod 22 are the same as those of the first tie rod 8 and the first sleeve rod 9. At the same time, the two ends of the second sleeve rod 22 are provided with the same threaded joints and nuts as the two ends of the first sleeve rod 9, which will not be elaborated further here.

[0050] Working Principle: When using this double-layer seedling rack for fruit and vegetable seedling cultivation, first insert the greenhouse pole 2 into the sleeve 11 at the top of the base 1 and fix it with the first clamp 12 to ensure the greenhouse pole 2 is securely installed. Next, fix the first shelf 3 and the second shelf 4 to the greenhouse pole 2 through the fixing component 6. Specifically, rotate the second locking block 62 to make the screw 63 rotate within the first locking block 61, thus firmly fixing the shelf. If it is necessary to adjust the height or angle of the shelf, the first pull rod 8 and the first sleeve rod 9 can be used. The first connecting seat 7 provides a rotation point for the first pull rod 8, allowing the first pull rod 8 to rotate relative to the first shelf 3. The first sleeve rod 9 adjusts its length by sliding, assisting the first pull rod 8 in achieving support and adjustment. At the same time, the connecting rod that is slidably connected to the inner wall of the first sleeve rod 9 is fixed to the greenhouse pole 2 through the locking component 10. Specifically, the limiting seat 101 provides a safety feature for the clamping block 102. The foundation is installed, and the two clamp the greenhouse pole 2 together. The relative positions are then fixed with fixing bolts 103. The nuts at both ends of the first set of poles 9 are tightened, which causes the threaded joint to retract and fix the first pull rod 8 and the connecting rod, thereby providing tension to the first placement plate 3 to achieve height adjustment and enhance the stability of the cultivation bed. The multiple sets of greenhouse poles 2 are connected by connecting pipes and diagonal pull rods 17 to improve the lateral stability of the cultivation bed. The outer side of the greenhouse poles 2 is provided with longitudinal rods 18 and fixed with second clamps 19 to enhance the longitudinal structural strength of the cultivation bed. In addition, the first placement plate 3 and the second placement plate 4 are connected by the second pull rod 21 and the second set of poles 22 to further enhance the connection stability. Its working principle is the same as that of the first pull rod 8 and the first set of poles 9. The bottom plate 13 of the drainage ditch can collect and guide rainwater. The clip 14 facilitates the installation of the first clip groove 15 and the second clip groove 16 for fixing the plastic film of the drainage ditch and the greenhouse film.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
