Description

Technical Field

[0001] This utility model relates to the field of cultivation rack technology, and in particular to a crop cultivation rack. Background Technology

[0002] In modern agricultural production, crop cultivation methods are developing towards diversification and efficiency. To fully utilize space resources and improve planting efficiency, crop cultivation racks are being used more and more widely. Whether in urban vertical farms, home balcony gardens, or large-scale greenhouse cultivation, cultivation racks play a crucial role. They not only provide support for crop growth but also optimize planting layouts, meet the growth needs of different crops, and thus improve crop yield and quality.

[0003] Currently, many cultivation racks adopt an integrated structural design, which makes transportation extremely inconvenient. Due to their large size and fixed shape, they require a significant amount of transport space, leading to a substantial increase in transportation costs. The integrated design also increases the difficulty of installation, typically requiring professional personnel with tools and considerable time for assembly, posing a high barrier to entry for ordinary growers. Furthermore, if any component of the integrated cultivation rack is damaged, the tightly connected parts are difficult to disassemble and replace individually, often necessitating the replacement of the entire rack. This undoubtedly increases maintenance and time costs, reduces the efficiency and economy of the cultivation rack, and fails to meet the requirements of modern high-efficiency agricultural production for flexible, convenient, and economical planting equipment. Therefore, to address these technical problems, this application proposes a crop cultivation rack. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology and propose a crop planting and cultivation frame. Each component, such as the base frame, top frame, support rod, movable sleeve, and shelf, is an independent module. When the pull rod is pulled, the pull rod moves the baffle together, which stretches the spring. Because the spring is stretched, the pull rod, which originally cooperated with the limiting groove to play a limiting role, no longer restricts the movable sleeve. At this time, the movable sleeve can slide freely on the outer wall of the support rod.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A crop cultivation rack includes a base frame and a top frame. Each of the four corners of the base frame and the top frame is connected to a support rod by a tenon. The outer walls of the support rods are connected to movable sleeves by limiting components. The two movable sleeves on the left side are fixedly connected to a tenon at their adjacent ends, and the two movable sleeves on the right side are fixedly connected to a tenon at their adjacent ends. The outer walls of the two tenons on the left side and the two on the right side are connected to shelves by support components.

[0007] Furthermore, the limiting component includes movable sleeves located on the outer walls of the four support rods. The two movable sleeves on the left are slidably connected to a pull rod at one end, and the two movable sleeves on the right are also slidably connected to a pull rod at one end. A baffle is fixedly connected to the outer wall of each of the pull rods, and a spring is provided on the outer wall of each of the pull rods.

[0008] Furthermore, one end of each of the multiple springs is connected to the movable sleeve, and the other end of each of the multiple springs is connected to the baffle.

[0009] Furthermore, the support assembly includes fixing sleeves located at the near ends of two tenons on the left and two on the right. The near ends of the two fixing sleeves on the left are connected by a connecting rod, and the near ends of the two fixing sleeves on the right are also connected by a connecting rod. The right ends of the two fixing sleeves on the left are fixedly connected with tenons, and the left ends of the two fixing sleeves on the right are also fixedly connected with tenons. Multiple tenons are provided on the inner wall of the shelf.

[0010] Furthermore, multiple equidistant limiting grooves are provided on the outer walls of the multiple support rods, and the multiple pull rods are all disposed within the limiting grooves.

[0011] Furthermore, a limiting ring is fixedly connected to the outer wall of the tenon, and the tenon and the limiting ring are located at the top and bottom ends of the support rod.

[0012] Furthermore, the limiting ring is made of rubber.

[0013] Furthermore, an opening is provided at the center of the top frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the cultivation rack adopts a modular design. Each component, such as the base frame, top frame, support rod, movable sleeve, and shelf, is an independent module. This design makes the cultivation rack more convenient to transport. Each module can be disassembled and packaged for transportation, greatly reducing the space occupied. At the installation site, it is also easy to assemble quickly, reducing the installation difficulty. Even non-professionals can easily complete the assembly according to the instructions. Moreover, when a module is damaged, it is not necessary to replace the entire cultivation rack. Only the damaged module needs to be replaced, which effectively reduces maintenance costs and time costs, and improves the efficiency and economy of the cultivation rack.

[0016] 2. In this utility model, when the pull rod is pulled, the pull rod moves the baffle along with it, which stretches the spring. Because the spring is stretched, the pull rod, which originally cooperated with the limiting groove to limit the movement, no longer restricts the moving sleeve. At this time, the moving sleeve can slide freely on the outer wall of the support rod. The height of the shelf can be flexibly adjusted according to the growth characteristics of different crops, making full use of space and maximizing planting benefits. Attached Figure Description

[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] Reference Figure 1 , Figure 2 and Figure 4An embodiment of this utility model provides: a crop planting and cultivation rack, including a base frame 1 and a top frame 2. The four corners of the base frame 1 and the top frame 2 are connected to support rods 4 by tenons 3 at their adjacent ends. The outer walls of the multiple support rods 4 are connected to movable sleeves 5 by movable sleeves 5, pull rods 6, baffles 7 and springs 8. The two movable sleeves 5 on the left side are fixedly connected to tenons 9 at their adjacent ends. The two movable sleeves 5 on the right side are fixedly connected to tenons 9 at their adjacent ends. The outer walls of the two tenons 9 on the left side and the two tenons 9 on the right side are connected to shelves 13 by fixed sleeves 10, connecting rods 12 and tenons 11.

[0026] Specifically, after adjusting the height of the movable sleeve 5, begin assembling the support rods 4. Carefully align the tenons 9 on the two support rods 4 on the same side with the pre-designed grooves on the fixing sleeve 10, and then slowly insert them. The fixing sleeve 10 is made of a material with a certain degree of elasticity. During the insertion of the tenons 9, the fixing sleeve 10 will undergo elastic deformation. When the tenons 9 are inserted into the appropriate position, the fixing sleeve 10 returns to its original shape and tightly locks the outer wall of the support rod 4. This completes the assembly of the two support rods 4 on the same side. Next, place the shelf 13 through the corresponding tenons 3 on its inner wall. 11. Insert the corresponding fixed sleeve 10 into the assembled shelf 13 to ensure stable support. Finally, connect the base frame 1 and top frame 2 to the assembled support rod 4 via tenons 1-3. The limiting ring 14 on the outer wall of the tenon 1-3 is made of rubber. Rubber has good flexibility and friction. During the connection process, the limiting ring 14 can not only accurately position the support rod 4 to ensure the accurate installation position of each component, but also enhance the stability of the connection and effectively prevent the support rod 4 from shaking. At this point, the entire cultivation rack is assembled and can be used for crop planting.

[0027] Reference Figure 2 , Figure 3 and Figure 5The four support rods 4 have movable sleeves 5 located on their outer walls. The two left movable sleeves 5 are slidably connected to pull rods 6 at opposite ends, as are the two right movable sleeves 5. Multiple pull rods 6 have baffles 7 fixedly connected to their outer walls, and multiple pull rods 6 have springs 8 installed on their outer walls. One end of each spring 8 is connected to a movable sleeve 5, and the other end is connected to a baffle 7. The two left fixed sleeves 10 are located near the ends of the two left and two right tenons 9. The two left fixed sleeves 10 are connected by a connecting rod 12 at their near ends, and the two right fixed sleeves 10 are connected by a connecting rod 12 at their near ends. One end is also connected by a connecting rod 12. The right ends of the two fixed sleeves 10 on the left are fixedly connected with tenons 3 11, and the left ends of the two fixed sleeves 10 on the right are also fixedly connected with tenons 3 11. Multiple tenons 3 11 are set on the inner wall of the shelf 13. Multiple support rods 4 have multiple equidistant limiting grooves 15 on their outer walls. Multiple pull rods 6 are set in the limiting grooves 15. The outer wall of tenon 1 3 is fixedly connected with a limiting ring 14. Tenon 1 3 and limiting ring 14 are set at the top and bottom ends of the support rod 4. The limiting ring 14 is made of rubber. An opening is opened in the center of the top frame 2.

[0028] Specifically, when preparing to assemble the crop planting and cultivation frame, the operator first grasps the pull rod 6 and pulls it outward. During the movement, the pull rod 6 moves the baffle 7 along with it, which stretches the spring 8. Because the spring 8 is stretched, the pull rod 6, which originally cooperated with the limiting groove 15 to limit the movement, no longer restricts the moving sleeve 5. At this time, the moving sleeve 5 can slide freely on the outer wall of the support rod 4. The grower slides the moving sleeve 5 along the support rod 4 according to the actual planting needs, such as planting crops of different heights or considering the spatial layout of the planting site. Once the desired height is reached, release the lever 6. At this point, the spring 8 contracts due to its own elasticity, causing the lever 6 to return to its original position. The lever 6 is then reinserted into the corresponding height limit slot 15, thus securing the movable sleeve 5 at that height. This achieves the height adjustment of the shelf 13. The top shelf 2 is located at the top of the cultivation rack and works in conjunction with the bottom shelf 1. They are connected by the support rod 4 to jointly construct the overall frame structure of the cultivation rack, enhancing its stability. The opening in the center of the top shelf 2 will not obstruct the growth of the crops on the top layer.

[0029] Working principle: Before assembling the cultivation rack, pull the pull rod 6 outward. The pull rod 6 moves the baffle 7 and stretches the spring 8. At this time, the movable sleeve 5 is no longer constrained by the pull rod 6 and the limiting groove 15 and can slide along the support rod 4. After moving the movable sleeve 5 to the appropriate position, release the pull rod 6. Under the elastic force of the spring 8, the pull rod 6 returns to its original position and inserts into the limiting groove 15 at the corresponding height, thereby fixing the position of the movable sleeve 5 and realizing the height adjustment of the shelf 13 to adapt to the growth needs of different crops or the layout of planting space. Then, align the tenons 9 on the two support rods 4 on the same side with the fixed sleeve. Insert the fixed sleeve 10 into the groove. Since the fixed sleeve 10 has a certain elasticity, the fixed sleeve 10 deforms during the insertion process. When it reaches the appropriate position, the fixed sleeve 10 returns to its original shape and locks into the outer wall of the support rod 4, so that the two support rods 4 on the same side can be assembled. Then, insert the shelf 13 into the fixed sleeve 10 of the corresponding layer height through the tenon three 11. Then connect the base frame 1 and the top frame 2 to the support rod 4 through the tenon one 3. The limiting ring 14 on the outer wall of the tenon one 3 is made of rubber, which not only plays a positioning role, but also enhances the stability of the connection and prevents the support rod 4 from shaking. The assembly of the cultivation rack is then completed.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
