Description

Technical Field

[0001] This utility model relates to the field of kiwifruit cultivation technology, and in particular to a cultivation shed that allows for convenient harvesting of kiwifruit. Background Technology

[0002] ① Traditional kiwifruit greenhouses typically use wooden triangular frames or simple bamboo structures as support, with a mesh frame formed by hand-tied longitudinal and transverse rods. These materials are susceptible to insect infestation and fungal decay in humid, open-air environments, especially in areas in contact with the ground where wood rot often occurs, leading to a loose and deformed greenhouse structure. The mortise and tenon joints or wire binding points repeatedly expand and contract with humidity changes, causing the frame to tilt or even partially collapse within two years. The additional load applied during manual climbing and maintenance further accelerates fatigue fracture at the joints, resulting in a severe lack of overall structural stability, making it difficult to meet the demands of modern large-scale orchard production.

[0003] ② To improve structural durability, the mainstream improvement scheme replaces the wooden frame with rust-resistant metal pipes, constructing a permanent pergola through welding hot-dip galvanized steel pipes. This structure uses vertical columns and horizontal beams welded orthogonally to form a rigid grid, with short support rods welded to the beam surfaces as a climbing support for branches. The metal material eliminates problems of insect infestation and decay, and its welded joint strength is significantly superior to wooden binding, capable of withstanding wind and rain erosion for over ten years without structural failure. The overall welded frame can maintain its spatial form even under extreme weather conditions such as typhoons, solving the core defects of traditional pergolas: short lifespan and poor disaster resistance.

[0004] ③ However, the welded metal structure introduces new operational contradictions: the welded climbing poles cannot be replaced independently. When a climbing pole is damaged due to excessive load deformation or accidental impact, repairs require cutting the weld points where the pole connects to the crossbeam. This process not only damages the anti-corrosion layer on the crossbeam surface, leading to potential rust, but also increases repair time due to limited working space on the roof. Simultaneously, the replaced pole needs to be re-welded, and spattering weld slag during this process can easily damage surrounding fruit and leaves. This interconnected repair logic essentially shifts the cost of replacing a single pole to the risk of damage to the entire structure and the cost of delayed agricultural work, becoming a technical bottleneck restricting the practicality of metal pergolas. Utility Model Content

[0005] The purpose of this utility model is to provide a planting shed that allows for easy harvesting of kiwifruit, solving the maintenance problems caused by the non-removable climbing poles in metal welded sheds. Specifically, this includes technical problems such as damage to the anti-corrosion layer caused by cutting the weld points, increased maintenance time due to limited operating space, and the risk of damage to surrounding crops during the re-welding process.

[0006] To achieve the above objectives, this utility model provides a planting shed for easy harvesting of kiwifruit, comprising multiple sets of connecting clips, each set consisting of two clips. Each connecting clip has a connecting hole on one side, into which a climbing rod is inserted. One end of each climbing rod has a spring, which is inserted into the connecting hole to press and fix the climbing rod within the hole. The connecting clips are respectively fitted onto the outside of the connecting horizontal tube, facilitating the climbing rod's climbing ability for kiwifruit branches and creating a harvesting space at the bottom of the climbing rod for easy kiwifruit harvesting.

[0007] The connecting horizontal pipes are fixedly installed on the transverse connecting end of the five-way connector, and multiple sets of connecting vertical pipes are fixedly installed on the longitudinal connecting end of the five-way connector.

[0008] The bottom vertical connection end of the five-way connector is fixedly installed with a support tube, and the upper and lower radial outer sides of the support tube are fixedly installed with corner lugs, and the center of the corner lugs is provided with a through hole.

[0009] The two adjacent sets of support tubes are stretched by steel cables through the through holes at the center of the corner lugs, so that triangular traction forces are generated between the support tubes.

[0010] A wedge is fixedly installed at the bottom end of the support pipe, a fixing plate is fixedly installed at the bottom end of the wedge, and multiple sets of diagonal bracing plates are fixedly installed between the wedge, the fixing plate and the support pipe.

[0011] The fixing plate has multiple sets of fixing holes for bolts to pass through, so that the fixing plate and the overall support pipe are connected to the ground concrete base.

[0012] This utility model discloses a planting shed for convenient harvesting of kiwifruit. Multiple pairs of connecting clips are fitted onto the outer side of horizontally arranged connecting tubes to form sliding support nodes. Climbing rods are installed in the connecting holes on the side walls of each clip via a plug-in method. Springs at the ends of the climbing rods are continuously compressed during insertion into the connecting holes, generating a reverse pushing force that ensures the climbing rod and the inner wall of the connecting hole form an adaptive and tight fit, achieving radial self-locking fixation without welding or bolts. This structure allows for directional assembly and disassembly of the climbing rods: during replacement, only pressure is applied to push the spring to axially pull out the rod; when a new rod is inserted, the spring automatically returns to its clamping force to complete positioning. The entire operation eliminates destructive cutting and high-temperature work, effectively avoiding damage to the anti-corrosion coating and hazards from maintenance debris, while maintaining the integrity of the horizontal frame.

[0013] The climbing poles are locked in a horizontal extension state, providing a uniformly distributed linear climbing carrier for kiwi branches. Workers can orderly bind new branches to the surface of the poles to guide their horizontal growth, forming a canopy of leaves perpendicular to the ground. The height of the climbing poles above the ground is set to match the field of vision and arm operation range when a person is naturally standing, so that workers walking in the greenhouse can clearly observe the distribution of fruits while maintaining an upright posture. When the forearm is naturally extended, the fingertips can directly touch the fruit stem to complete the picking action, eliminating the additional operational load of climbing or bending posture required by traditional elevated structures.

[0014] The adjustable characteristic of the connecting clip along the axial direction of the connecting horizontal tube allows the spacing of the entire row of climbing poles to be flexibly adjusted according to the planting density; the spring snap-fit ​​mechanism enables independent maintenance of individual poles, and only the local poles need to be replaced during maintenance without disturbing the overall frame; finally, the non-destructive disassembly and assembly structure with dynamically adjustable spacing reduces maintenance costs, and the optimized height design improves picking comfort, achieving a technological breakthrough in the large-scale harvesting of kiwifruit from both the perspectives of operational efficiency and ergonomics.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figures 1-4 .

[0023] This utility model provides a planting shed for convenient harvesting of kiwifruit. The shed uses a connecting horizontal pipe 105 as its horizontal frame foundation. Multiple pairs of connecting clips 101 are fitted around the outer circumference of the connecting horizontal pipe 105, forming a symmetrical support point with each pair of connecting clips 101. Climbing rods 103 are inserted into connecting holes 102 on the side walls of the connecting clips 101. Springs 104 mounted at the ends of the climbing rods 103 deform under pressure when inserted into the connecting holes 102, generating a reverse elastic force that causes the climbing rods 103 to radially press against the connecting holes. The inner wall of 102 forms a self-locking fixation, which enables the climbing pole 103 to be quickly assembled, disassembled, and positioned horizontally. Workers manually wrap the new kiwi fruit branches around the outside of the climbing pole 103, so that the branches grow in an orderly manner in a predetermined direction. The height of the climbing pole 103 from the ground is set in the range of 1.6 meters to 1.7 meters. This height matches the range of operation of an adult's arms hanging naturally when standing upright. When workers walk upright in the greenhouse, their eyes can be at eye level with the fruit bunches, and their fingertips can naturally touch the base of the fruit, which significantly reduces the need to bend over and climb, and improves the efficiency of continuous harvesting.

[0024] The two ends of the connecting horizontal tube 105 are respectively inserted into the transverse connecting ports of the five-way connector 106 to form a rigid connection. The longitudinal connecting ports of the five-way connector 106 are fastened with multiple parallel connecting vertical tubes 107. The connecting vertical tubes 107 and the connecting horizontal tubes 105 are orthogonal to form a grid-like planar load-bearing frame. This frame evenly transfers the weight of the branches carried by a single climbing pole 103 to the nodes of the longitudinal and transverse tubes, avoiding the deformation of the frame due to excessive local branches. The bottom vertical connecting port of the five-way connector 106 is vertically welded with a support tube 108 as the core load-bearing column. The radial outer walls of the upper and lower parts of the support tube 108 are respectively welded with symmetrically distributed corner lugs 109. The through holes 110 drilled in the center of the corner lugs 109 are arranged at a specific inclination angle.

[0025] Adjacent support pipes 108 are connected by steel cables 111 that cross through through holes 110 to form a continuous diagonal tension. The upper steel cable 111 passes through the through hole 110 of the upper corner lug 109 of one support pipe 108 and then diagonally connects to the through hole 110 of the lower corner lug 109 of the other support pipe 108. The lower steel cable 111 passes through in the opposite direction along a mirror path. After the ends of the steel cables 111 are pre-tightened with fasteners, a bidirectional triangular tension is generated between the support pipes 108. This structure effectively resists the effects of fruit trees bearing fruit on only one side. The eccentric moment and the horizontal impact of strong winds; the bottom end face of the support pipe 108 is welded with a wedge block 112 with a gradually expanding cross section, the bottom surface of the wedge block 112 is welded with a rectangular fixing plate 113, and multiple diagonal bracing plates 114 are arranged radially and welded to the column body of the support pipe 108, the intersection of the inclined surface of the wedge block 112 and the top surface of the fixing plate 113 respectively. The diagonal bracing plates 114 convert the vertical load of the support pipe 108 into diagonal pressure and distribute it to the edge of the fixing plate 113, suppressing the bending moment effect of the anchor and preventing cracking at the root of the column.

[0026] Fixing plate 113 has fixing holes 115. After the bolt passes through the fixing hole 115, it is screwed into the base sleeve pre-embedded in the foundation. By applying pre-tightening force, fixing plate 113 and ground base form a pull-out connection. Diagonal bracing plate 114 cooperates to resist the shear force generated by wind load on the bolt. Finally, a five-level collaborative working system is formed, consisting of detachable branch positioning module, ergonomic picking layer, five-way node force transmission frame, steel cable 111 triangular anti-sway system and diagonal bracing anchor component, which significantly improves picking efficiency and greenhouse stability in large-scale kiwi fruit planting scenarios.

[0027] Working principle: When new kiwifruit branches grow, workers actively wrap the branches around the outside of the climbing pole 103. The climbing pole 103 is inserted into the connecting hole 102 on the side of the connecting clip 101 via a spring 104 at one end. When the spring 104 is compressed, it generates a reverse elastic force, causing the climbing pole 103 to fit tightly against the inner wall of the connecting hole 102, achieving self-locking and forming a stable and quickly detachable branch support point. This design keeps the climbing pole 103 in a horizontal position at all times, preventing the branches from drooping due to their own weight or wind force, while also simplifying later maintenance and replacement operations—simply press the spring 104 to remove the old pole and insert the new one. The height of the climbing pole 103 from the ground is set to approximately 1.6- At 1.7 meters, this height aligns with the operating height of a person in a natural standing posture; workers can directly see the fruit clusters without climbing or bending over, and their arms can directly touch the fruit in a naturally hanging state, significantly shortening the harvesting process and reducing fatigue. Combined with the horizontal extension frame formed by the connecting clip 101 fitted onto the connecting horizontal tube 105, it further expands the lateral climbing area of ​​the branches, preventing overlapping and shading of the fruit clusters, and forming a vertically spaced, orderly light-receiving band. The connecting horizontal tubes 105 are interconnected through the lateral ports of the five-way connector 106, forming a lateral main framework; simultaneously, the longitudinal ports of the five-way connector 106 connect to multiple connecting vertical tubes 107, forming a longitudinally extending grid structure. This crisscrossing tube frame system evenly distributes the supporting force of the single-point climbing pole 103 to the overall frame, allowing the plant load to be transferred from point to surface, avoiding localized overload deformation.The vertical port at the bottom of the five-way connector 106 connects to the support pipe 108, which serves as the core load-bearing column, transferring all the load of the upper branches and fruits to the foundation. The corner lugs 109 welded to the upper and lower sides of the support pipe 108 provide anchoring points for the steel cables 111. Adjacent support pipes 108 are cross-tensioned by the steel cables 111 that diagonally pass through the upper and lower corner lugs 109. The steel cables 111 generate prestress under the tightening of the turnbuckles, forming a rigid triangular mechanical unit between the support pipes 108. This structure offsets the lateral load and strong wind impact caused by uneven growth of the fruit trees, significantly suppresses the swaying of the greenhouse, and ensures the spatial stability of the grid frame. The bottom end of the support pipe 108 is welded to the fixing plate 113 through wedges 112. Multiple diagonal bracing plates 114 are radially welded to the support pipe 108, wedges 112, and fixing plate 113. At the junction of 3, vertical pressure is converted into diagonal support force, greatly enhancing the bending resistance of the column; the bolt holes in the fixing plate 113 allow it to connect with the base embedded in the concrete foundation or hard ground, anchoring the entire shed to the foundation; the diagonal bracing structure further disperses the shear force of wind load on the anchor bolts, preventing the shed from tilting due to loose bolts, and providing lasting stability for long-term outdoor use; the entire structure achieves efficient branch positioning and maintenance through the replaceable spring 104 snap-on climbing pole 103; the horizontal grid layout close to human height creates an unobstructed picking space; the five-way pipe frame and the steel cable 111 triangular traction together construct a wind-resistant and load-resistant stability system; the wedge block 112 diagonal bracing and base anchoring ensure long-term structural rigidity—these four elements work together to achieve the core goals of high-efficiency picking and low maintenance costs in standardized kiwi fruit production.
