Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural planting technology, specifically relating to a modular climbing frame for agricultural planting. Background Technology
[0002] Ecological planting refers to an agricultural development model that, under the premise of protecting and improving the agricultural ecological environment, follows the laws of ecology and ecological economics, and uses systems engineering methods and modern science and technology for intensive management. In particular, when planting vines, it is necessary to build a climbing trellis for the vines to climb.
[0003] Currently, the climbing frames used for growing climbing vegetables in agriculture are generally of a cross-braced support structure. Although the structure is simple, the overall construction of the climbing frame is time-consuming and labor-intensive. Furthermore, the position of the longitudinal support rods after cross-bracing cannot be adjusted according to the type of climbing vegetable. Therefore, in order to solve the above problems and improve the flexibility and convenience of the climbing frame, it is necessary to design a climbing frame that is easy to build, easy to disassemble, and easy to store. Utility Model Content
[0004] The technical problem solved by this utility model is to provide a modular climbing frame for agricultural planting. By setting a hinge seat at the bottom of the top rod, the upper intersecting branch pipes 1 and 2 can be detachably hinged to the bottom of the top rod, realizing the modular and rapid assembly and disassembly of the branch pipe assembly on the top rod. Multiple sets of longitudinal support components are installed with adjustable height between adjacent branch pipes 1 and adjacent branch pipes 2, which can adjust the support position according to the climbing height and density requirements of different vine plants. The adjustment of the support position of the longitudinal support components is convenient and quick, improving the adaptability to diverse planting scenarios. The modular design allows the top rod, branch pipe assembly, and longitudinal support assembly to be disassembled and separated, without occupying too much space when stored. Moreover, the components have no easily damaged binding structure, and can be reused for multiple seasons of planting, reducing the cost of agricultural production materials.
[0005] The technical solution adopted by this utility model is: a modular climbing frame for agricultural planting, including a top rod, multiple hinge seats on the bottom surface of the top rod, and a branch pipe assembly with the same number of hinge seats. The branch pipe assembly includes a branch pipe one and a branch pipe two. The conical tips at the bottom of the branch pipe one and the branch pipe two are inserted into the soil, and the upper ends of the branch pipe one and the branch pipe two are hinged to the hinge seats at their intersection. Multiple sets of longitudinal support assemblies are installed between adjacent branch pipe one and between adjacent branch pipe two in an adjustable manner.
[0006] The longitudinal support assembly includes a pull rope, with anti-disengagement buckles fixed at both ends of the pull rope. Both branch pipe one and branch pipe two are equipped with connecting plates with two ring holes that are height adjustable, and the anti-disengagement buckles at both ends of the pull rope are respectively hooked to the two connecting plates at the same height.
[0007] Furthermore, multiple through holes are evenly distributed on branch pipe one and branch pipe two, and a connecting plate with one end fitted onto branch pipe one and branch pipe two is positioned on branch pipe one and branch pipe two by a stop pin inserted into the corresponding position of the through hole. The anti-disengagement buckle is hooked to the other end of the connecting plate.
[0008] Furthermore, the hinge seat is a groove-shaped structure with the opening facing downwards. The upper end of the hinge seat is fixed to the bottom surface of the top rod, and the intersection of the upper ends of branch pipe one and branch pipe two is located in the groove of the hinge seat. The upper ends of branch pipe one and branch pipe two are hinged to the bottom of the top rod by a pin passing through the hinge seat and the upper end holes of branch pipe one and branch pipe two.
[0009] Furthermore, both ends of the top rod are provided with multiple connecting holes, and the opposite ends of adjacent top rods are detachably fixed together by connecting plates with connecting holes distributed vertically as needed for construction.
[0010] Advantages of this utility model compared to the prior art: 1. This technical solution achieves modular and rapid assembly and disassembly of the branch pipe assembly on the top rod by setting a hinge seat at the bottom of the top rod, which allows the upper intersecting branch pipes one and two to be detachably hinged to the bottom of the top rod. 2. This technical solution has multiple sets of longitudinal support components installed in an adjustable manner between adjacent branch pipe 1 and adjacent branch pipe 2. The support position can be adjusted according to the climbing height and density requirements of different vine plants.

This technical solution has a simple structure, novel design, and is easy and quick to assemble and disassemble.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0015] A modular climbing frame for agricultural planting includes a top rod 1, multiple hinge seats 4 on the bottom surface of the top rod 1, and a branch pipe assembly equal in number to the hinge seats 4. Each branch pipe assembly includes branch pipe 2 and branch pipe 3, with the conical tips at their bottoms inserted into the soil. The upper ends of branch pipe 2 and branch pipe 3 intersect and are hinged to the hinge seats 4. Multiple sets of longitudinal support assemblies are installed with adjustable height between adjacent branch pipes 2 and adjacent branch pipes 3. In this structure, by setting hinge seats 4 at the bottom of the top rod 1, the intersecting branch pipes 2 and 3 are detachably hinged to the bottom of the top rod 1, enabling rapid modular assembly and disassembly of the branch pipe assembly on the top rod 1. The adjustable height installation of multiple sets of longitudinal support assemblies between adjacent branch pipes 2 and adjacent branch pipes 3 allows for adjustment of the support position according to the climbing height and density requirements of different vines. The convenient and quick adjustment of the longitudinal support position enhances adaptability to diverse planting scenarios. The specific structure of the longitudinal support assembly is as follows: The longitudinal support assembly includes a pull rope 5, with anti-disengagement buckles 6 fixed at both ends. Each of the branch pipes 2 and 3 has a height-adjustable connecting plate 7 with two ring holes 10. The anti-disengagement buckles 6 at both ends of the pull rope 5 are respectively hooked to the two connecting plates 7 at the same height, providing a specific and feasible structural solution for the connection between the longitudinal support assembly and the branch pipes 2 and 3. This ensures that the longitudinal support assembly can be stably installed between adjacent branch pipes 2 and 3, providing a climbing support surface for the vines. The pull rope 5 is hooked to the connecting plates 7 at both ends via anti-disengagement buckles 6, which effectively prevent the pull rope 5 from being pulled by the vine climbing force. The pull rope 5 is detached from the connecting plate 7, which improves the connection efficiency. During installation, it is important to note that after the two ends of the pull rope 5 are connected to the anti-detachment buckle 6, the pull rope 5 needs to be tightened. The tightness of the pull rope 5 needs to be manually controlled. To achieve the desired tension of the pull rope 5, turnbuckles from the farm's inventory can be used. One end of the pull rope 5 is connected to the anti-detachment buckle 6, and the other end is connected to the hanging ring on one end of the turnbuckle. Then, the other end of the turnbuckle is hung on the connecting plate 7 at the corresponding position. The pull rope 5 is tightened by adjusting the turnbuckle. When using turnbuckles, in order to avoid the turnbuckles getting too hot under the sun during the day and affecting the plants, the metal part of the turnbuckle needs to be wrapped with heat-insulating material such as cloth strips.
[0016] The height-adjustable positioning structure of the connecting plate 7 on branch pipe 1 (2) and branch pipe 2 (3) is as follows: Multiple through holes 8 are evenly distributed on branch pipe 1 (2) and branch pipe 2 (3). The connecting plate 7, with one end fitted onto branch pipe 1 (2) and branch pipe 2 (3), is positioned on branch pipe 1 (2) and branch pipe 2 (3) by a stop pin 9 inserted into the corresponding position of the through hole 8. The anti-disengagement buckle 6 is hooked to the other end of the connecting plate 7. Using this structure, by removing and inserting the stop pin 9, the connecting plate 7 can be quickly positioned and adjusted, allowing for rapid control of its installation height on branch pipe 1 (2) and branch pipe 2 (3), thus achieving rapid adjustment of the height of the longitudinal support component. Simultaneously, the stable fit between the stop pin 9 and the through hole 8 prevents the connecting plate 7 from shifting under the pull of vines or external forces, ensuring the stability of the climbing frame. The entire adjustment process requires no complex tools, is simple and efficient, and can quickly adapt to the climbing needs of different vine growth stages, significantly reducing adjustment difficulty compared to traditional binding structures.
[0017] The hinge structure of branch pipe 2 and branch pipe 3 at the bottom of the top rod 1 is as follows: The hinge seat 4 is a groove-shaped structure with the opening facing downwards. The upper end of the hinge seat 4 is fixed to the bottom surface of the top rod 1, and the intersection of the upper ends of branch pipe 2 and branch pipe 3 is located in the groove of the hinge seat 4. The upper ends of branch pipe 2 and branch pipe 3 are hinged to the bottom of the top rod 1 by a pin 13 passing through the upper end holes of the hinge seat 4 and branch pipe 2 and branch pipe 3. In the above structure, the groove-shaped hinge seat 4 can form a lateral limit on the ends of branch pipe 2 and branch pipe 3, which cooperates with the shaft of the pin 13. The fixed orientation effectively prevents the branch pipe from shifting or detaching from the hinge seat under stress, ensuring the stability of the connection between the top rod 1 and the branch pipe assembly, thereby improving the overall load-bearing capacity of the climbing frame. Simultaneously, the connection method using a pin 13 passing through the hinge seat 4 and the upper holes of branch pipe 1 and branch pipe 2 3 allows for easy assembly; simply passing the pin 13 through the corresponding hole completes the hinge connection, and pulling out the pin 13 separates the top rod 1 from the branch pipe assembly, eliminating the need for complex disassembly operations. This meets the requirements of modular climbing frames for convenient assembly and disassembly, reducing operational difficulty during use. The top rod 1 has multiple connecting holes 11 at both ends, and the opposite ends of adjacent top rods 1 can be detachably fixed together by connecting plates 12 with connecting holes 11 distributed vertically as needed for construction. The above structure allows adjacent top rods 1 to be detachably fixed together by connecting plates 12 with connecting holes 11, and the overall length of the climbing frame can be flexibly adjusted according to the size of the planting area and the area of vine planting, breaking the length limitation of a single top rod 1 and adapting to agricultural planting scenarios of different scales.
[0018] This technical solution has a simple structure, novel design, and is easy and quick to assemble and disassemble. The modular design allows the top rod 1, branch pipe assembly, and longitudinal support assembly to be disassembled and separated, without taking up too much space when stored. In addition, the components have no easily damaged binding structure and can be reused for multiple seasons of planting, reducing the cost of agricultural production materials.
