Technical Field
[0001] This utility model relates to the field of grape planting equipment technology, and more specifically, to an adjustable grape planting rack. Background Technology
[0002] Grapes, as a widely cultivated economic crop, have high requirements for supporting structures, light conditions, pest and disease control, and water and fertilizer management during their growth process. Current grape cultivation techniques have the following shortcomings: Firstly, grapes are susceptible to pecking by birds during the ripening stage. Existing bird protection measures mostly use fixed protective nets, which are cumbersome to install and dismantle, and occupy space during the non-bird protection season, affecting vineyard ventilation and field operations. Secondly, management operations such as spraying and watering during grape cultivation require manual hand tools, which is not only labor-intensive but also results in uneven spraying of pesticides, easily leading to missed or over-sprayed areas, affecting the effectiveness of pest and disease control and the utilization rate of water and pesticides. Thirdly, the support and climbing structure of traditional planting trellises has a single function and cannot meet the support needs and light access of grape vines at different growth stages, which is not conducive to improving grape quality and yield.
[0003] To address the aforementioned issues, this invention proposes an adjustable grape planting trellis. By integrating a retractable perforated protective net with an integrated spraying structure, it effectively solves the problems of convenient bird protection and precise pesticide application. At the same time, it optimizes the vine support structure to meet the needs of high-efficiency grape cultivation. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable grape planting rack to solve the problems mentioned in the background art, such as the inconvenience of disassembling and assembling bird protection nets and the low efficiency and unevenness of spraying operations.
[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: Adjustable grape growing racks are used to improve the above problems.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model 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 this utility model.
[0017] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0018] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes an adjustable grape growing rack, including a support frame 10 that is vertically inserted into the ground, and also including... The main pole 20 is fixedly installed at the top of the support frame 10. The main pole 20 is made of hollow galvanized steel pipe. An inlet is provided on the outer wall of the end near the support frame 10. The inlet can be connected to an external liquid pump or water-fertilizer mixing equipment through a pipe to provide a liquid delivery interface for spraying or fertilizing. Climbing frame 30 is installed in the middle section of main pole 20; Extension frame 40 is installed at the top of the main rod 20; Rain cover 50, which is installed above the extension frame 40; The retractable perforated protective part 60 is evenly installed on the outer side wall of the rain shield 50.
[0021] like Figure 1 and Figure 3 As shown, the climbing frame 30 includes support rods 310 installed on the outer wall of the main pole 20. Climbing wires 320 are fixedly connected between adjacent support rods 310. The support rods 310 are inclined, fixed to the middle section of the main pole 20 at an angle of 30°-45°, and evenly distributed along the circumference of the main pole 20. This inclination angle is optimized to avoid both excessively small angles that would make climbing difficult and excessively large angles that would cause the vines to sag under weight. The climbing wires 320 fixed between adjacent support rods 310 form a "grid-like support surface," allowing the grapevines to naturally climb along the climbing wires 320 during their growth period. The inclined structure of the support rods 310 guides the vines to extend outwards, preventing them from densely entwining around the main pole 20, ensuring ventilation and light penetration between branches and leaves, and reducing disease growth. Simultaneously, the support rods 310 are hollow structures and connected to the main pole 20, serving both as "support" and "drug distribution channels."
[0022] like Figure 1 , Figure 2 and Figure 3As shown, the extension frame 40 includes a crossbar 410 fixedly installed at the top of the main pole 20. The horizontal and vertical sections of the crossbar 410 are fixedly connected to evenly distributed extension wires 420. The crossbar 410 is fixed to the top of the main pole 20, and its horizontal and vertical sections form a "cross-shaped extension frame." The extension wires 420 fixed to the outer wall form a three-dimensional support network at the top. When the grapes enter their vigorous fruiting period, the vine growth increases and the fruit weight increases. The "cross structure" of the crossbar 410 can evenly distribute the weight of the vines and fruit in all directions, preventing excessive local load from causing the main pole 20 or support pole 310 to bend. The extension wires 420 provide the vines with more growing space, guiding the fruit to be evenly distributed, reducing mutual shading between fruits, improving light utilization, and promoting sugar accumulation in the fruit. Furthermore, the crossbar 410 is also a hollow structure, connected to the main pole 20 and support pole 310, forming a "top-level diversion pipe" for pesticide delivery.
[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the main rod 20 has a liquid inlet on the outer wall near the support frame 10. The liquid inlet of the main rod 20 adopts a G1 / 2-inch threaded interface, which can be quickly connected to the outlet of the external liquid pump through a matching hose to ensure a leak-free seal. The main rod 20, the support rod 310, and the cross rod 410 are all hollow rod structures that are interconnected. The top of the support rod 310 and the cross rod 410 are fixedly connected to evenly distributed nozzles 70. The outlet of the nozzle 70 is equipped with a nozzle 710. External liquid or water-fertilizer mixture is injected through the liquid inlet at the bottom of the main rod 20. Because the main rod 20, the support rod 310, and the cross rod 410 are interconnected hollow structures, the liquid flows along the path of "main pipe of main rod 20 → middle layer diversion pipe of support rod 310 → top layer diversion pipe of cross rod 410" under the pressure of the external pump, and finally flows to each nozzle 70. This path design allows the pesticide solution to be rapidly dispersed from a single inlet to the middle vine growth area and the top fruit concentration area of the planting rack, covering the core area of grape growth. The nozzles 70 fixed to the top of the support rods 310 and cross rods 410 are connected to the hollow rod body. The nozzles 710 at the end of the nozzles 70 operate using pressure atomization technology: when the pesticide solution enters the nozzle 710, under the pump pressure (typically 0.2-0.3 MPa), the solution is sprayed at high speed from the small aperture of the nozzle 710, colliding violently with the air and breaking into tiny droplets. These atomized droplets have the characteristics of wide coverage and strong adhesion, evenly adhering to both sides of the vine leaves and the surface of the fruit, avoiding the problems of "missed spraying" and "overspraying" in traditional manual spraying. This also reduces pesticide waste, increasing utilization by more than 30%, and the atomized spraying will not cause impact damage to the delicate fruit.
[0024] like Figure 1 and Figure 4As shown, the retractable perforated protective part 60 includes a storage box 610 installed on the outer wall of the rain shield 50. A winding shaft 620 is rotatably connected to the inner wall of the storage box 610, and a protective shell 630 is fixedly connected to the outer wall of the storage box 610. One end of the winding shaft 620 passes through the storage box 610 and extends into the inner cavity of the protective shell 630. The extended end of the winding shaft 620 is rotatably connected to the protective shell 630. A sleeve is fixedly connected between the extended end of the winding shaft 620 and the outer wall of the storage box 610. The return spring 640 is placed inside the storage box 610. A hollow protective net 650 is fixedly connected to the outer wall of the winding shaft 620. A stabilizing rod 660 is fixedly connected to one end of the hollow protective net 650 that passes through the storage box 610. A pull rope 670 is fixedly connected to the middle section of the stabilizing rod 660. The hollow protective net 650 is made of nylon. The stabilizing rod 660 is a metal rod with a length adapted to the storage box 610. The pull rope 670 is made of wear-resistant nylon rope with a length adapted to the height of the planting rack. During the peak period of bird pecking 1-2 weeks before the grapes ripen, the operator pulls the pull rope 670 from the ground: one end of the pull rope 670 is fixed to the stabilizing rod 660. When pulled, the stabilizing rod 660 moves downward, and the stabilizing rod 660 pulls the hollow protective net 650 outward from inside the storage box 610. At this time, the winding shaft 620 inside the storage box 610 rotates synchronously with the extension of the perforated protective net 650. The end of the winding shaft 620 extending into the protective shell 630 stretches the return spring 640, putting it into an energy storage state. When the stabilizing rod 660 moves down to contact the ground, it is fixed to the tie ring 110 of the adjacent planting rack by the pull rope 670, and the perforated protective net 650 is fully unfolded, forming a "cylindrical protective barrier" surrounding the middle layer of the fruit area of the planting rack. The return spring 640 is made of stainless steel with a spring constant of 5-8 N / mm. This ensures that it can pull the winding shaft 620 to complete the storage of the protective net without causing difficulty in unfolding the net due to excessive elasticity. The mesh of the perforated protective net 650 effectively prevents birds from entering and reaching the fruit. At the same time, the perforated structure does not block light or obstruct air circulation, preventing the fruit from being affected by insufficient oxygen or light, thus protecting the quality. After the fruit is picked, there is no need for bird protection. When the operator releases the pull rope 670, the return spring 640, which is in an energy-storing state, releases its elastic potential energy, generating a reverse pulling force that drives the winding shaft 620 to rotate in the opposite direction. As the winding shaft 620 rotates, it gradually winds the perforated protective net 650 back onto its outer wall. At the same time, the stabilizing rod 660 moves upward under the pull of the perforated protective net 650 until the perforated protective net 650 is completely retracted into the storage box 610. The return spring 640 then returns to its natural extension state, completing the storage. The entire storage process does not require manual handling of the perforated protective netting 650. It achieves "automatic return to position" by relying on the elastic reset of the return spring 640. The operation is convenient and does not take up space in the vineyard, making it easy for subsequent field operations such as pruning and fertilization.
[0025] like Figure 1As shown, a tie ring 110 is fixedly connected to the support frame 10. The tie ring 110 is used to fix the pull rope 670 so that the stabilizer 660 is in contact with the ground. The tie ring 110 can also be used to fix the guide rope of the grape vine to prevent the vine from falling over due to the wind and improve the multi-functionality of the support system.
[0026] like Figure 1 and Figure 2 As shown, the rain shelter 50 is made of transparent polycarbonate sheet with a thickness of 3-5mm. Its size is larger than the coverage area of the extension frame 40, forming a "wide at the top and narrow at the bottom" sheltering structure. When it rains, rainwater falls on the surface of the rain shelter 50. Because the rain shelter 50 has a certain curvature (slightly convex), the rainwater flows around the rain shelter 50, avoiding direct dripping onto the fruit and vines below. This reduces the impact of rainwater on the fruit skin and also reduces the risk of fruit cracking due to excessive water absorption. The light transmittance of the polycarbonate sheet used in the rain shelter 50 can reach more than 85%, close to natural light. The rain shelter does not block sunlight during the process: after the sunlight passes through the rain shelter 50, it can normally shine on the vines of the middle climbing frame 30 and the fruit of the top extension frame 40, meeting the light requirements for grape photosynthesis. Grapes need sufficient light to accumulate sugar during the ripening stage, avoiding the problem of "insufficient light and reduced fruit sweetness" caused by traditional opaque rain shelters.
[0027] The hollow rods of the main rod 20, support rod 310, and cross rod 410 of the support system also provide liquid channels for the spray pipe 70 and nozzle 710 of the spraying system, avoiding the need for repeated laying of structures. The rain shield 50 not only blocks rainwater, but also provides an installation base for the storage box 610 of the retractable protective unit 60, making the protective unit and the top extension rack 40 structurally integrated. When the retractable protective unit 60 is unfolded, its hollow protective netting 650 surrounds the fruit-concentrated area of the climbing frame 30 precisely matching the protection without any blind spots. The spray nozzles 710 of the spraying system are distributed at the top of the support rods 310 and cross rods 410, corresponding to the positions of the vines and fruits, so that "wherever there is a need for growth, there are spray nozzles 710 to spray the pesticide".
[0028] All technical features in this embodiment can be freely combined according to actual needs.
[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
