Description

Technical Field

[0001] This invention relates to the field of agricultural planting facilities technology, specifically to a passion fruit trellis that is easy to install and disassemble. Background Technology

[0002] Passion fruit, as a perennial fruit, has soft and rapidly growing vines that require trellises for support to achieve optimal growing space, yield, and quality. Trellises not only prevent vines from creeping along the ground, reducing pests and diseases, but more importantly, they optimize light and ventilation for the plants, promote flower and fruit development, and facilitate field management and harvesting. They are an indispensable infrastructure for standardized passion fruit cultivation.

[0003] Currently, common passion fruit trellises mainly use either cement pillars with wire mesh structures, or welded steel pipe frames with wire mesh. Cement pillar trellises typically require a pre-cast concrete foundation to fix the cement pillars in the ground, followed by the construction of a crisscrossing wire mesh on top of the pillars. Welded steel pipe trellises use galvanized steel pipes welded together to form a fixed frame structure, upon which steel wire or plastic mesh is laid. Both methods provide basic support for passion fruit cultivation and are widely used in agricultural production.

[0004] However, existing trellis technology has significant shortcomings. Installation is complex and time-consuming; the cement foundation requires curing time, and welding operations require specialized personnel and equipment. Secondly, because the structure is fixed and non-adjustable, it's impossible to adjust the grid size and canopy height according to the growth characteristics of different varieties. Most importantly, dismantling is extremely difficult; cement pillars require destructive removal, and welded structures require cutting, resulting in severe material damage and low reusability. Especially when crop rotation or soil sterilization is needed, the dismantling cost of traditional trellises often exceeds their construction cost, seriously impacting planting efficiency. Therefore, there is an urgent need to develop a passion fruit trellis that is easy to install and dismantle, flexibly adjustable, and reusable to solve these problems of existing technology. Summary of the Invention

[0005] The purpose of this invention is to overcome the problems in the prior art and provide a passion fruit trellis that is easy to install and disassemble.

[0006] This invention provides a passion fruit trellis that is easy to install and disassemble, including a column unit composed of multiple segmented column rods detachably connected end-to-end via quick connectors to provide vertical support; a canopy support unit including a main support beam rotatably connected to the top of the column unit via a universal joint, and a grid-like canopy surface overlapping the multiple main support beams to form a growth plane for the passion fruit vines; and a diagonal bracing unit including an adjustable ground anchor and a cable, one end of which is connected to the upper part of the column unit and the other end to the adjustable ground anchor to enhance the overall stability of the trellis; the quick connectors, the universal joints, the connection between the grid-like canopy surface and the main support beam, and the connection between the two ends of the cable are all quick-connect structures.

[0007] Preferably, the quick connector includes a retaining ball with an internal spring and an annular groove that matches the retaining ball; when the two segmented column rods are connected, the retaining ball springs into the annular groove under the action of the spring to achieve locking.

[0008] Preferably, the universal joint is a ball joint, including a ball seat fixedly connected to the top of the column unit, and a ball head fixedly connected to the end of the support beam and embedded in the ball seat. A tightening bolt for locking the ball head is provided on one side of the ball seat. By loosening the tightening bolt, the inclination angle of the support beam relative to the horizontal plane can be adjusted, and by tightening it, the angle can be fixed.

[0009] Preferably, the gridded canopy is assembled from multiple horizontal and vertical rods by connecting buckles at their intersections. The connecting buckles are integrally molded plastic parts, with a first slot at the bottom for the horizontal rods to be inserted and a second slot at the top, perpendicular to the first slot, for the vertical rods to be inserted. The rods can be clamped and fixed by pressing.

[0010] Preferably, the connecting buckles have various specifications, and the cross spacing between the horizontal and vertical bars defined by the connecting buckles of different specifications is different. By selecting the connecting buckles of different specifications, the gridded canopy with different grid sizes can be quickly assembled.

[0011] Preferably, the upper surface of the supporting main beam is provided with a continuous guide rail along the length direction, and the bottom of the peripheral rods of the gridded canopy is provided with a sliding groove that matches the guide rail. By aligning the sliding groove and sliding it into the guide rail, the gridded canopy can be quickly installed and positioned on the supporting main beam.

[0012] Preferably, the adjustable ground anchor includes a central rod and a helical blade welded to the lower part of the central rod, the upper part of the central rod having a connecting ring for connecting the cable and a transverse through hole for a lever to be inserted for rotation.

[0013] Preferably, the cable is a steel wire rope or a high-strength nylon rope, and a threaded adjuster is provided at one end near the adjustable ground anchor. The threaded adjuster is threadedly engaged with a screw fixed on the adjustable ground anchor connecting ring. By rotating the threaded adjuster, the cable can be tensioned or loosened.

[0014] Preferably, the segmented column poles and the supporting main beams are both made of thin-walled steel pipes or aluminum alloy pipes with galvanized surfaces, and the poles of the gridded canopy are made of glass fiber poles or carbon fiber poles.

[0015] Preferably, it also includes a protective sleeve, made of rubber or plastic, fitted over the outside of the quick connector.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The innovative combination of segmented uprights and quick connectors in the upright unit changes the traditional installation method of the scaffolding. The quick connector adopts a structural design with spring-loaded ball bearings that match the annular groove. When two segmented uprights are joined, the ball bearings automatically spring into the annular groove under the action of the spring to lock them in place. This process requires no tools and can be completed by a single person in a short time. At the same time, the canopy support unit uses universal connectors to achieve quick connection between the support beam and the upright unit. The connection between the grid canopy and the support beam also adopts a quick-connect structure. Combined with the quick-connect design at both ends of the cables in the cable-stayed reinforcement unit, the installation time of the entire scaffolding system is shortened compared to traditional welded scaffolding, and the disassembly time is reduced, which greatly improves construction efficiency. The ball joint design of the universal connector allows for stepless adjustment of the tilt angle of the main support beam relative to the horizontal plane. Growers can flexibly adjust the angle of the canopy according to the terrain slope to ensure that the passion fruit vines receive optimal sunlight. At the same time, the grid canopy adopts a standardized quick-connect structure, which allows for rapid adjustment of the grid density according to the characteristics of the passion fruit variety and the growth stage. This meets the needs of purple fruit varieties with dense branching that require small grid support, and also adapts to the characteristics of yellow fruit varieties with thick main vines that require large grid extension, resulting in more even fruit distribution and improved harvesting efficiency.

[0017] The adjustable ground anchors and cables of the inclined reinforcement unit significantly enhance the overall stability of the trellis. The adjustable ground anchors, with their central rod and helical blade structure, can be easily screwed into the soil using a lever principle. The anchoring depth can be adjusted according to soil conditions, providing reliable pull-out resistance. All connections are designed to prevent loosening, avoiding accidental detachment during use and ensuring the trellis system remains stable and reliable throughout the entire growth cycle.

[0018] The overall modular design and quick-connect structure significantly improve the installation efficiency, structural stability, and adaptability of the trellis system. The column unit uses segmented column rods combined with quick connectors, allowing for rapid connection by a single person and ensuring the stability of vertical support. The roof support unit connects to the columns via universal joints, enabling stepless adjustment of the main support beam to adapt to different terrain slopes. The grid roof uses a quick-release structure, allowing for rapid assembly into grids of different sizes to meet the growth requirements of various passion fruit varieties. The inclined bracing reinforcement unit enhances overall wind resistance through adjustable ground anchors and threaded, fine-tuning cables, ensuring long-term stability. Furthermore, all connections can be installed and disassembled without specialized tools, increasing installation efficiency many times over compared to traditional methods. The materials can be reused multiple times, reducing costs and making it particularly suitable for the needs of modern agriculture where frequent adjustments to planting layouts are required.

[0027] The following is in conjunction with the appendix Figures 1-7To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art.

Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "inner," "outer," "upper," "lower," "far," "near," "front," and "rear" are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly. The drawings in this invention are not strictly drawn to scale; the specific dimensions and quantity of each structure can be determined according to actual needs. The drawings described in this invention are merely structural schematic diagrams.

[0029] This invention provides a passion fruit trellis that is easy to install and disassemble, such as... Figures 1-4 As shown, the system includes a column unit 1, which consists of multiple segmented column rods detachably connected end-to-end via quick connectors 2 to provide vertical support; a canopy support unit, which includes a main support beam 3 rotatably connected to the top of the column unit 1 via universal connectors 5, and a grid canopy 4 overlapping the multiple main support beams 3 to form a growth plane for the passion fruit vines; and a diagonal bracing reinforcement unit 6, which includes an adjustable ground anchor 61 and a cable 62. One end of the cable 62 is connected to the upper part of the column unit 1, and the other end is connected to the adjustable ground anchor 61 to enhance the overall stability of the canopy. The quick connectors 2, universal connectors 5, the connection points between the grid canopy 4 and the main support beam 3, and the connection points at both ends of the cable 62 are all quick-connect structures.

[0030] In this embodiment, the innovative combination of segmented column rods and quick connectors 2 in column unit 1 changes the traditional installation method of the scaffold. The quick connector 2 adopts a structural design in which a locking ball 202 with an internal spring 201 matches an annular groove 203. When two segmented column rods are connected, the locking ball 202 automatically springs into the annular groove 203 under the action of the spring 201 to lock. This process does not require any tools and a single person can complete the installation of the column in a short time. At the same time, the canopy support unit uses universal connectors 5 to achieve quick connection between the main support beam 3 and column unit 1. The connection between the grid canopy 4 and the main support beam 3 also adopts a quick-connect structure. Combined with the quick-connect design at both ends of the cable 62 in the inclined cable reinforcement unit 6, the installation time of the entire scaffold system is shortened compared with the traditional welded scaffold, and the disassembly time is reduced, which greatly improves the construction efficiency. The ball joint design of the universal connector 5 enables stepless adjustment of the tilt angle of the main supporting beam 3 relative to the horizontal plane. Growers can flexibly adjust the angle of the canopy according to the terrain slope to ensure that the passion fruit vines receive optimal sunlight. At the same time, the grid canopy 4 adopts a standardized quick-connect structure, which allows for rapid adjustment of the grid density according to the characteristics of the passion fruit variety and the growth stage. This meets the needs of the purple fruit variety when the branches are dense and require small grid support, and also adapts to the characteristics of the yellow fruit variety when the main vine is thick and requires large grid extension, resulting in more uniform fruit distribution and improved harvesting efficiency.

[0031] The overall stability of the trellis is significantly enhanced by the combination of adjustable ground anchors 61 and cables 62 in the inclined reinforcement unit 6. The adjustable ground anchors 61 adopt a central rod and helical blade structure, which can be easily screwed into the soil through the lever principle. The anchoring depth can be adjusted according to soil conditions, providing reliable pull-out resistance. All connection parts are designed to prevent loosening, avoiding accidental loosening during use and ensuring that the trellis system remains stable and reliable throughout the entire growth cycle.

[0032] The overall modular design and quick-connect structure innovation significantly improve the installation efficiency, structural stability, and adaptability of the trellis system. The column unit 1 uses segmented column rods combined with quick connectors 2, enabling a single person to quickly complete the connection and ensuring the stability of the vertical support. The trellis support unit connects to the columns via universal connectors 5, allowing the main support beam 3 to be infinitely adjustable to adapt to different terrain slopes. Meanwhile, the grid-like trellis 4 uses a quick-release structure, allowing for rapid assembly into grids of different sizes to meet the growth requirements of different passion fruit varieties. The inclined bracing reinforcement unit 6 enhances the overall wind resistance through adjustable ground anchors 61 and threaded fine-tuning cables 62, ensuring long-term stability. Furthermore, all connection structures can be installed and disassembled without specialized tools, increasing installation efficiency many times over compared to traditional methods. The materials can be reused multiple times, reducing costs and making it particularly suitable for the needs of modern agriculture that requires frequent adjustments to planting layouts.

[0033] Preferred, such as Figures 1-5 As shown, the quick connector 2 includes a retaining ball 202 with an internal spring 201 and an annular groove 203 that matches the retaining ball 202; when the two segmented column rods are connected, the retaining ball 202 is springed into the annular groove 203 under the action of the spring 201 to achieve locking.

[0034] In this embodiment, the quick connector 2 is specifically defined, employing a cooperative structure of spring 201, retaining ball 202, and annular groove 203. When two segmented column rods are joined, the retaining ball 202 automatically springs into the annular groove 203 under the action of spring 201 to achieve locking; this achieves truly tool-free operation, significantly reducing installation difficulty, allowing even non-professionals to quickly complete assembly; the preload of spring 201 provides a continuous and stable connection force, avoiding the problem of loosening due to vibration in traditional bolt connections; the annular groove 203 is designed to allow for a certain angular deviation, improving installation tolerance. This significantly enhances the installation efficiency and connection reliability of column unit 1, providing stable foundation support for the entire scaffolding system;

[0035] The locking ball 202 automatically locks under the action of the spring 201, ensuring a stable connection of the column. A single person can quickly complete the docking or disassembly, which is more efficient than traditional bolt connections. The protective sleeve design prevents mud and sand from entering the locking ball 202 mechanism, extending its service life. At the same time, the diameter of the locking ball 202 can be adapted to different pipe diameters, making it highly compatible and suitable for various agricultural shed needs.

[0036] Preferred, such as Figures 1-5 As shown, the universal connector 5 is a ball joint, including a ball seat 501 fixedly connected to the top of the column unit 1, and a ball head 502 fixedly connected to the end of the supporting main beam 3 and embedded in the ball seat 501. A tightening bolt 503 for locking the ball head 502 is provided on one side of the ball seat 501. By loosening the tightening bolt 503, the inclination angle of the supporting main beam 3 relative to the horizontal plane can be adjusted, and the angle can be fixed after tightening.

[0037] In this embodiment, the multi-degree-of-freedom rotation of the ball head 502 within the ball seat 501 allows the supporting main beam 3 to be steplessly adjusted within a range of ±15°, perfectly adapting to different terrain slopes; the tightening bolt 503 provides reliable locking force, ensuring that the adjusted angle remains stable under load; this structure has strong torque resistance, avoiding the problem of easy loosening of traditional hinge points. This gives the canopy support unit terrain adaptability, solving the problem that traditional fixed canopies cannot adapt to sloping planting, and adapting to complex terrains such as hills and slopes; the chrome-plated surface of the ball head 502 has a low coefficient of friction, ensuring long-term stability.

[0038] Preferred, such as Figures 1-7As shown, the gridded canopy surface 4 is assembled from multiple horizontal rods 401 and vertical rods 402 through connecting buckles 403 at their intersections. The connecting buckles 403 are integral plastic molded parts. The lower part of the buckle is provided with a first slot 404 for the horizontal rods 401 to be inserted, and the upper part is provided with a second slot 405 perpendicular to the first slot 404 for the vertical rods 402 to be inserted. The rods can be clamped and fixed by pressing.

[0039] In this embodiment, the plastic material is corrosion-resistant, lightweight, and has a certain degree of elasticity, which can buffer wind loads and live loads; the vertical slot design ensures the squareness of the grid and avoids the deformation problems that are easily caused by traditional binding methods; the press-type installation is many times more efficient than traditional binding, enabling the grid-like canopy 4 to achieve true modular rapid assembly, which greatly reduces the difficulty and time cost of canopy construction, and the assembly speed is fast and the time required is short, many times faster than traditional wire binding; the plastic material is resistant to acids and alkalis, has no metal corrosion problems, and at the same time reduces shock and noise, avoiding mechanical damage during vine growth.

[0040] Preferred, such as Figures 1-7 As shown, the connecting buckle 403 has various specifications. The cross spacing of the horizontal bar 401 and the vertical bar 402 defined by the connecting buckle 403 of different specifications is different. By selecting connecting buckles 403 of different specifications, gridded canopy surfaces 4 with different grid sizes can be quickly assembled.

[0041] In this embodiment, the connecting buckle 403 is further limited to various specifications, providing different cross spacings. The importance of this limitation lies in the following: through the standardized and serialized buckle design, various grid sizes such as 15cm×15cm, 20cm×20cm, and 25cm×25cm can be quickly assembled; secondly, buckles of different specifications use the same interface size, ensuring interchangeability; the large-spacing buckles are equipped with reinforcing ribs, which improves the load-bearing capacity and allows the trellis system to adapt to the growth characteristics of different passion fruit varieties. Small grids are used for purple varieties to promote branching, while large grids are used for yellow varieties to facilitate the extension of the main vine, achieving true variety adaptability and reducing the difficulty of spare parts management.

[0042] Preferred, such as Figures 1-5 As shown, the upper surface of the supporting main beam 3 is provided with continuous guide rails 7 along the length direction, and the bottom of the peripheral rods of the gridded canopy 4 is provided with sliding grooves 8 that match the guide rails 7. By aligning the sliding grooves 8 and sliding them into the guide rails 7, the gridded canopy 4 can be quickly installed and positioned on the supporting main beam 3.

[0043] In this embodiment, a sliding groove 8 is provided at the bottom of the grid-like canopy 4. The sliding groove 8 system provides a precise positioning reference, ensuring that the flatness deviation of the grid-like canopy 4 is small after installation. The sliding installation method is more efficient and safer than the hoisting method. The sliding groove 8 can be expanded to integrate other functional modules, such as lighting systems or irrigation pipes, enabling the canopy support unit to achieve fast and accurate positioning and installation, ensuring the flatness and stability of the entire canopy.

[0044] Preferred, such as Figures 1-4 As shown, the adjustable ground anchor 61 includes a central rod and a helical blade welded to the lower part of the central rod. The upper part of the central rod is provided with a connecting ring for connecting the cable 62 and a transverse through hole for inserting a lever to rotate.

[0045] In this embodiment, a central rod and helical blade structure is adopted. The helical blade can be inserted into the soil by rotation, eliminating the need for excavation and concrete pouring, thus improving installation efficiency. The transverse through-hole on the central rod allows for the use of levers, greatly reducing the installation effort. The multi-stage connecting ring design allows for adjustment of the anchoring point height according to soil conditions. This makes the installation of the cable-stayed reinforcement unit 6 simple and quick, and the anchoring depth can be adjusted according to geological conditions, ensuring the reliability of the reinforcement effect.

[0046] Preferred, such as Figures 1-4 As shown, the cable 62 is a steel wire rope or a high-strength nylon rope. A threaded adjuster is provided at one end near the adjustable ground anchor 61. The threaded adjuster is threadedly engaged with a screw fixed on the connecting ring of the adjustable ground anchor 61. By rotating the threaded adjuster, the cable 62 can be tensioned or loosened.

[0047] In this embodiment, the cable 62 is equipped with a threaded adjuster, which enables fine-tuning of the tension. The threaded adjustment provides precise tension control and improves adjustment accuracy. The built-in locking ring prevents loosening due to vibration and ensures long-term tension stability. It can dynamically compensate for changes in rope length caused by temperature variations. This allows the cable-stayed reinforcement unit 6 to precisely adjust the prestress according to the actual load conditions, ensuring the stability of the scaffolding system under wind and live loads.

[0048] The cable 62 uses high-strength nylon rope or steel wire rope, with a threaded adjuster at the end for fine-tuning to ensure uniform force on each anchor point; the adjuster has a built-in nylon locking ring to prevent loosening due to vibration and can dynamically compensate for rope length fluctuations caused by humidity changes to maintain constant tension on the canopy surface.

[0049] Preferred, such as Figures 1-2 As shown, the segmented column poles and supporting main beams 3 are made of thin-walled steel pipes or aluminum alloy pipes with galvanized surfaces, and the poles of the gridded canopy 4 are made of glass fiber poles or carbon fiber poles.

[0050] In this embodiment, the columns and main beams are made of galvanized thin-walled steel pipes or aluminum alloy pipes, and the galvanized layer avoids rust; the four poles of the grid-like canopy are made of glass fiber or carbon fiber, which is only the cost of stainless steel, and is insulated and protected against lightning strikes. The long overall lifespan ensures the long-term durability of the canopy system in humid agricultural environments and greatly extends its service life.

[0051] Preferred, such as Figures 1-2 As shown, it also includes a protective sleeve made of rubber or plastic, which is fitted over the quick connector 2.

[0052] In this embodiment, a protective sleeve design, made of rubber or plastic, is added. Firstly, it effectively prevents mud and moisture from entering the quick connector 2, avoiding failure of the locking bead 202 mechanism; secondly, it provides cushioning protection, reducing the risk of damage during transportation and installation; and finally, different color markings facilitate component identification and management. This further improves the reliability and service life of the quick connector 2, ensuring the long-term stable operation of the entire column unit 1.

[0053] A rubber or plastic protective sleeve covers the quick connector 2, providing dust and water protection, cushioning against external impacts, and improving the transport integrity rate; at the same time, the air layer design prevents burns to operators.

[0054] The method of using the passion fruit trellis of the present invention, which is easy to install and disassemble, is as follows: First, connect the segmented support columns end-to-end using quick connectors 2, and lock them in place by pressing the locking beads 202. This allows for quick installation by a single person. After the columns are installed, adjust the angle of the supporting main beam 3 using the ball joint universal connector 5, and secure it with tightening bolts 503 to ensure the canopy is level. Then, select the appropriate connecting clips 403 to assemble the grid canopy 4, embedding the horizontal rods 401 and vertical rods 402 into the slots to form a uniformly distributed vine growth plane. Finally, push the sliding grooves 8 along the main beam guide rails 7 into position to complete the canopy installation.

[0055] At the perimeter of the column, the spiral blades of the adjustable ground anchor 61 are screwed into the soil to a certain depth to form a stable anchor point. One end of the cable 62 is connected to the upper part of the column, and the other end is fixed to the ground anchor through the threaded adjuster. The rotating adjuster precisely controls the tension, so that the force on each anchor point is balanced, ensuring overall stability.

[0056] In the early stages of passion fruit vine growth, new shoots are manually guided to distribute evenly across the gridded canopy surface 4, avoiding overcrowding in any area. For different varieties, the connecting clips 403 can be quickly replaced to adjust the grid spacing, optimizing light transmission and ventilation. As the fruit load increases, local support can be enhanced by adding inclined cables 62 or replacing with high-load-bearing clips to adapt to the needs of different growth stages.

[0057] Disassembly is performed in reverse: first loosen the pull cable 62 adjuster, slide out the gridded canopy 4, and then press the locking bead 202 to separate the column section. No professional tools are required throughout the process. After disassembly, the parts are covered with protective covers to prevent dust and rust. The columns and main beams are stacked horizontally, and the carbon fiber rods are stored in the dark. This canopy can be repeatedly disassembled and reassembled, which greatly reduces the cost of crop rotation and is particularly suitable for modern and efficient agricultural applications.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
