Abstract
Description
Technical Field
[0001] This utility model relates to the field of mango cultivation rack technology, and in particular to a special integrated dwarfing cultivation rack for mangoes. Background Technology
[0002] The mango-specific integrated dwarfing trellis is a fruit tree support system that typically controls tree height within the range of 1.8-2.3m. By restricting the longitudinal growth of the trunk and branches, it guides the canopy to expand laterally, forming a compact, dwarf tree shape. This height range is designed based on ergonomics and mechanized operation requirements, satisfying both orchard ventilation and lighting optimization needs and facilitating manual pruning, fruit thinning, and harvesting operations. The system improves orchard ventilation and light conditions through dwarfing, promoting the accumulation of photosynthetic products, while reserving passageways for mechanized operations. This increases yield per unit area by more than 30%, significantly reduces the intensity of manual management, and provides a technological carrier for intensive production in modern mango industrial parks.
[0003] Traditional mango cultivation trellises typically use fixed, rigid structures that cannot meet the dynamic growth needs of fruit trees. Prematurely shaped trellises during the sapling stage restrict root expansion, inhibiting early canopy development. During the growing season, the lack of extendable support forces branches to grow haphazardly, forming a dense canopy and causing insufficient light penetration into the inner canopy. Once in full production, static trellises struggle to support the weight of the enlarging fruit, often leading to branch splitting. More seriously, traditional structures cannot be adjusted to suit the tree's morphology, resulting in a 30%-50% increase in pruning intensity and exacerbating the risk of pests and diseases. This lack of adaptability throughout the entire growth cycle directly increases mango orchard management costs by more than 20% and leads to uneven fruit quality, with a marketable fruit rate consistently below 60%, severely hindering the improvement of industry profitability.
[0004] Therefore, this application provides a mango-specific integrated dwarfing cultivation rack to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to provide a special integrated dwarfing cultivation frame for mangoes, which solves the problem that existing cultivation frames cannot be adapted to the shape of the tree.
[0006] To solve the above-mentioned technical problems, this utility model provides a mango-specific integrated dwarfing cultivation rack, which includes multiple vertically arranged lifting components, with a support component connecting adjacent lifting components.
[0007] The support assembly includes a first support arm hinged to the top of the lifting assembly, and a second support arm hinged to the ends of two adjacent first support arms. The first and second support arms guide the mango tree branches and the canopy to expand directionally along the plane by pulling on the mango tree branches.
[0008] A further improvement of the present invention is that the lifting assembly includes a first lifting pole and a second lifting pole nested together. The second lifting pole extends and retracts within the rod cavity of the first lifting pole, and the outer wall of the first lifting pole has multiple vertically arranged pin holes, with elastic pins installed in the pin holes for adjusting the vertical height.
[0009] A further improvement of the present invention is that: a ground insert is provided at the bottom of the first lifting pole, the ground insert includes a conical spike-shaped anchor rod inserted into the soil, and multiple limiting rings are provided at the top of the conical spike-shaped anchor rod, the limiting rings being used to fix the first lifting pole.
[0010] A further improvement of this utility model is that the adjustable height range of the first and second lifting poles is 1.8-2.3m.
[0011] A further improvement of the present invention is that the support assembly includes a hinge plate disposed on the top of the second lifting pole, the two sides of the hinge plate being hinged to the first support arm respectively, and fixing bolts extending vertically from both sides of the hinge plate.
[0012] A further improvement of the present invention is that: the first support arm includes a support plate that is hinged to the hinge plate, and an arc-shaped through hole is opened on the support plate corresponding to the fixing bolt. The fixing bolt passes through the arc-shaped through hole and is used to lock the rotation angle of the first support arm.
[0013] A further improvement of this utility model is that the angle adjustment range of the first support arm is 45° above and below the horizontal line.
[0014] A further improvement of this utility model is that the hinge between the first support arm and the second support arm is a movable hinge.
[0015] By adopting the above technical solution, this utility model has the following beneficial effects:
[0016] 1. This utility model provides a mango-specific integrated dwarfing cultivation frame. This frame, through the coordinated design of a longitudinally integrated lifting component and hinged first and second support arms, achieves precise adaptation to the mango tree's morphology throughout its entire life cycle. During the sapling stage, the height of the lifting pole is adjusted using elastic pins to control the tree within the dwarfing range of 1.8-2.3m. Simultaneously, the ±45° angle adjustment of the support arms guides the directional expansion of branches, pulling and binding the branches to the first or second support arm, increasing the initial canopy development space by 40%. After entering the growth stage, the lifting component, along with the arc-shaped through-holes and fixing bolts of the support component, dynamically expands the angle of the traction plane, increasing the canopy light transmittance from 40% in the traditional model to 75%, effectively inhibiting branch closure. In the peak production period, the conical spike-like anchor rods and support components work together to bear the weight of the fruit, preventing branch breakage due to the weight of mature mangoes.
[0017] 2. This utility model provides a mango-specific integrated dwarfing cultivation frame. This frame facilitates precise control of the mango tree's canopy morphology, improves light energy efficiency, and features a three-dimensional guiding mechanism in the traction plane formed by the first and second support arms. The canopy is forced to expand laterally, and combined with the height restriction of the lifting components, the naturally growing tree height of 3.5-4m is compressed to 1.8-2.3m, increasing the photosynthetically effective leaf area from 55% to 85%. This also increases light exposure to the fruit, improving fruit color uniformity. Attached Figure Description

[0029] The present invention will be further explained below with reference to specific embodiments.
[0030] like Figures 1-6As shown in the figure, this embodiment provides a mango-specific integrated dwarfing cultivation frame, including multiple longitudinally arranged lifting components 1. The lifting components 1 realize the full-cycle adjustment of the overall height of the cultivation frame, adapting to the canopy expansion needs of mangoes at different growth stages. Through dynamic height adjustment, it avoids the canopy being suppressed in the young tree stage and sinking under the weight of the fruit in the high-yield stage. A support component 2 connects two adjacent lifting components 1. The lifting components 1 include a first lifting upright 11 and a second lifting upright 12 nested together. The first lifting upright 11 is a static reference pole, and the second lifting upright 12 is a dynamic telescopic pole. The second lifting upright 12 telescopically extends and retracts within the pole cavity of the first lifting upright 11. The outer wall of the first lifting upright 11 has multiple vertically arranged pin holes 13, and elastic pins (not shown in the figure) are set in the pin holes 13 for adjusting the vertical height. The adjustable height range of the first lifting upright 11 and the second lifting upright 12 is 1.8-2.3m. The bottom of the first lifting pole 11 is provided with a ground insert 14, which includes a conical spike anchor 141 inserted into the soil. The top of the conical spike anchor 141 is provided with multiple limiting rings 142. The limiting rings 142 are used to fix the first lifting pole 11. The conical spike anchor 141 is welded to the soil and inserted to a depth of 80cm. The limiting rings 142 hug the outer wall of the first lifting pole 11 and are fixed by bolts to prevent torsion.
[0031] like Figures 1-6 As shown, in this embodiment, the support component 2 constructs a canopy traction plane to guide the branches to expand directionally and bear the weight of the fruit. The support component 2 includes a first support arm 21 hinged to the top of the lifting component 1, and a second support arm 22 hinged to the ends of two adjacent first support arms 21. The first support arms 21 and the second support arms 22 guide the mango branches and the canopy to expand directionally along the plane by traction. The support component 2 includes a hinge plate 23 disposed at the top of the second lifting pole 12. The two sides of the hinge plate 23 are respectively hinged to the first support arms 21, and fixing bolts 24 are vertically extended from both sides of the hinge plate 23. The first support arm 21 includes a support plate 25 hinged to the hinge plate 23. An arc-shaped through hole 26 is opened on the support plate 25 corresponding to the fixing bolt 24. The fixing bolt 24 passes through the arc-shaped through hole 26 and is used to lock the rotation angle of the first support arm 21. When the fixing bolt 24 is tightened, it generates a normal friction force to counteract the disturbance of the angle caused by the growth of the branches. The angle adjustment range of the first support arm 21 is 45° above and below the horizontal line, and the arc-shaped through hole 26 has a central angle of 90°. The support arm can be adjusted by ±45°, which improves the uniformity of light transmission in the canopy by 40%. The hinge between the first support arm 21 and the second support arm 22 is a movable hinge. The movable hinge design allows the second support arm 22 to dynamically adjust with the angle of the first support arm 21, forming an adaptive traction grid that accurately matches the expansion needs of the canopy at each growth stage.
[0032] This utility model also provides the working principle of a special integrated dwarfing cultivation rack for mangoes:
[0033] When using the mango-specific integrated dwarfing cultivation frame, firstly, the conical spike-shaped anchor rod 141 of the ground insert 14 is vertically inserted into the soil near the mango tree, and the first lifting pole 11 is fixed by the limiting ring 142; then, the second lifting pole 12 is telescopically adjusted to the target height and locked using the pin hole 13; next, the support component 2 is installed, the first support arm 21 is connected to the lifting pole through the hinge plate 23, the angle of the support plate 25 is adjusted and then passed through the arc-shaped through hole 26 and locked with the fixing bolt 24, and the second support arm 22 is movably hinged to the end of the adjacent first support arm 21 to form a traction grid; finally, the mango branches are tied to the first support arm 21 or the second support arm 22, and the lifting height and opening angle are dynamically adjusted according to the growth stage to achieve directional expansion of the canopy and load-bearing adaptation.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
