Description

Technical Field

[0001] This utility model relates to a detachable windproof and heat-insulating cover for fruit tree canopies, belonging to the technical field of fruit tree auxiliary equipment. Background Technology

[0002] The growth status of fruit trees is closely related to their yield and quality, while harsh weather conditions such as low temperatures and strong winds in the natural environment are key limiting factors affecting the healthy growth of fruit trees. Especially during the budding, flowering, and fruit-setting periods in spring and autumn, if the trees encounter cold snaps, strong winds, or temperature drops, low temperatures can easily cause frost damage to flower buds and withering of new shoots, while strong winds may cause branches to break and fruits to fall off, directly reducing the economic benefits of the orchard. Therefore, windproofing and heat-insulating the canopy of fruit trees has become an important measure to ensure the profitability of fruit tree cultivation.

[0003] Currently, windproof and heat-insulating devices for fruit tree canopies on the market are mainly divided into two categories: one is fixed protective structures, such as fixed plastic greenhouses or protective sheds formed by wooden frames and insulation films. Although these devices can provide stable windproof and heat-insulating effects, they have significant drawbacks. Their size is fixed and cannot be adjusted according to changes in canopy width and tree height at different growth stages of the fruit trees. As the fruit trees grow year by year, the fixed structure easily compresses the canopy, affecting branch extension and photosynthesis. At the same time, fixed structures are costly to build and difficult to dismantle. They cannot be flexibly removed during non-protection seasons (such as the high-temperature period in summer), which can easily lead to excessively high temperatures and poor ventilation inside the canopy, which in turn can cause fruit tree diseases.

[0004] Another type is simple protective devices, such as directly wrapping the tree canopy with insulating non-woven fabric, or covering the tree with insulating material after temporarily building a support frame with bamboo poles, wire, etc. Although such devices are low in cost and easy to operate, their protective stability is extremely poor: on the one hand, direct wrapping protection easily leads to the non-woven fabric sticking tightly to the branches, affecting the ventilation of the tree canopy, and the non-woven fabric is easily torn and displaced under the action of wind, failing to form a continuous and effective protection; on the other hand, temporary supports are mostly built once, with a loose structure and weak wind resistance. In strong winds, the supports are prone to collapsing, not only losing their protective function, but the scattered support materials may also cause secondary damage to the fruit trees. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a detachable windproof and heat-insulating cover for fruit tree canopies.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A detachable windproof and heat-insulating cover for fruit tree canopies includes two telescopic frames arranged in a parallel and symmetrical structure. Each telescopic frame includes a guide sleeve, each guide sleeve having a sliding hole, and a telescopic rod slidably connected within the sliding hole. A guide sleeve two is provided on one side of each guide sleeve and telescopic rod one, each guide sleeve having a sliding hole, and a telescopic rod two slidably connected within the sliding hole. A non-woven breathable protective component is provided on the upper side of the telescopic frame.

[0007] Through the above technical solution, the core support structure of this detachable fruit tree canopy windproof and heat-insulating cover consists of two parallel and symmetrically arranged telescopic frames. The telescopic frames achieve bidirectional telescopic adjustment through a nested sliding structure of guide sleeves and telescopic rods. Lateral telescopic adjustment: The guide sleeve has a sliding hole, and the telescopic rod slides in the sliding hole. By pulling the telescopic rod in the sliding hole, the overall length of a single telescopic frame in the lateral direction can be changed, thus adapting to fruit trees with different canopy sizes. Longitudinal telescopic adjustment: Guide sleeve 2 is fixedly installed on the same side of guide sleeve 1 and telescopic rod 1. Guide sleeve 2 has a sliding hole 2 inside. Telescopic rod 2 slides in and is engaged with sliding hole 2. By pulling and moving telescopic rod 2 in sliding hole 2, the overall height of telescopic frame in the longitudinal direction can be changed, thereby adapting to fruit trees of different heights. Windproof and heat-insulating cover: Non-woven breathable protective components are installed on the upper side of the telescopic frame. After the telescopic frame is adjusted to match the size of the fruit tree, the non-woven breathable protective components can completely cover the canopy of the fruit tree, forming a surrounding protective space. This not only blocks the invasion of external cold wind, but also maintains a stable temperature inside the cover through the heat-insulating properties of the non-woven fabric.

[0008] With bidirectional telescopic adjustment between telescopic rod one and guide sleeve one and telescopic rod two and guide sleeve two, there is no need to customize protective devices for fruit trees of different heights and crown widths. It can be flexibly adapted to various fruit tree specifications, reducing the equipment purchase cost for growers. The symmetrical structure of the telescopic frame ensures that the non-woven breathable protective components evenly cover the tree canopy, forming a complete protective space, effectively isolating the tree from cold winds, reducing the frost damage to fruit tree branches and flower buds caused by low temperatures, and avoiding the problem of branches breaking due to strong winds. The sliding connection structure of the guide sleeve and telescopic rod does not need to be permanently fixed. It can be adjusted again later according to the growth of the fruit trees, such as when the canopy widens, or it can be disassembled and stored during non-windproof and heat-insulating seasons, such as summer, to avoid aging and wear caused by long-term exposure of the device.

[0009] Preferably, each of the two guide sleeves and the telescopic rod is provided with a side plate on one side, and a ground anchor is provided on one side of the side plate.

[0010] Through the above technical solution, side plates are fixedly installed on the guide sleeves of the two telescopic frames and on the same side as the telescopic rods. Ground anchors are installed on the side of the side plates facing the ground. When in use, the ground anchors are vertically inserted into the soil around the fruit trees, so that the side plates are close to the ground. Through the interlocking force between the ground anchors and the soil, the bottom of the telescopic frame is fixed to the ground, limiting the horizontal displacement and vertical tilt of the telescopic frame.

[0011] The firm anchoring to the soil can offset the horizontal thrust of strong winds on the insulation cover, preventing the telescopic frame from being blown over or displaced. At the same time, it can prevent the telescopic frame from tilting or collapsing due to excessive weight when snow accumulates on the non-woven breathable protective components in winter, ensuring the reliability of the protective device in severe weather. The insertion-type fixing of the ground anchors does not require complicated tools. Growers can complete the installation and dismantling manually. The operation threshold is low and it will not damage the soil structure of the orchard, thus avoiding affecting the root growth of the fruit trees. The ground anchor and the side plate are fixedly connected. When disassembling, simply pull the ground anchor out of the soil and store it together with the telescopic frame. It can be reused later, reducing the frequency of equipment replacement.

[0012] Preferably, a connecting plate is provided between the two telescopic rods, and a fastening bolt is rotatably connected to one side of the connecting plate. One end of the fastening bolt is threaded through to one side of the telescopic rod.

[0013] Through the above technical solution, a connecting plate is set between the two telescopic rods of the telescopic frame. One side of the connecting plate is rotatably connected to one of the telescopic rods via a rotating shaft, and the other side has a threaded hole adapted to the fastening bolt. When the telescopic frame is adjusted laterally to the target length, the connecting plate is rotated to fit against the side wall of the other telescopic rod. The fastening bolt is passed through the threaded hole of the connecting plate and screwed into the preset threaded hole of the telescopic rod. Through the threaded locking force of the bolt, the two telescopic rods and the connecting plate are fixed as a whole, restricting the sliding displacement of the telescopic rod within the guide sleeve.

[0014] By tightening the bolts, the adjusted length of the telescopic frame can be fixed, preventing the telescopic rod one or telescopic rod two from sliding on their own due to vibration, wind or other factors during use. This ensures that the insulation cover always matches the size of the fruit tree canopy and prevents gaps from forming. The connecting plate connects two parallel telescopic frames into a stable frame structure, reducing the independent force on a single telescopic frame and improving the overall resistance to deformation. The locking mechanism can be released simply by loosening the fastening bolts, and the size of the telescopic frame can be adjusted again. The operation is convenient, and the protection range can be flexibly adjusted according to the growth cycle of the fruit trees without disassembling the entire device.

[0015] Preferably, the upper side of the guide sleeve two is connected with a locking bolt through a thread, and one end of the locking bolt can abut against one side of the telescopic rod two.

[0016] Through the above technical solution, a through threaded hole is opened on the upper side of the guide sleeve 2, and the locking bolt is threadedly engaged with the threaded hole; when the telescopic rod 2 slides to the target height in the sliding hole 2 of the guide sleeve 2, the locking bolt is turned clockwise, so that one end of the bolt gradually extends into the sliding hole 2 and closely abuts against the side wall of the telescopic rod 2. Through the static friction between the bolt and the telescopic rod 2, the vertical sliding of the telescopic rod 2 in the sliding hole 2 is restricted, thereby fixing the longitudinal height of the telescopic frame.

[0017] The locking bolts' contact-type fixing allows for stepless adjustment. There is no need to pre-set multiple positioning holes on the telescopic rod. Growers can flexibly adjust the longitudinal dimensions of the telescopic frame according to the actual height of the fruit trees. The adjustment accuracy is higher, ensuring that the non-woven breathable protective components just cover the top of the canopy, avoiding insufficient height leading to exposed top branches or excessive height causing material waste. Locking and unlocking can be completed simply by using a wrench or manually tightening the locking bolts, without complicated disassembly steps. A single person can quickly complete the height adjustment, making it especially suitable for large-scale fruit tree protection operations in orchards. The static friction locking, rather than rigid buckle locking, avoids wear on the side wall of the telescopic pole during repeated adjustments, thus extending the service life of the telescopic pole.

[0018] Preferably, the nonwoven breathable protective component includes several first pillars and several second pillars. The first pillar is disposed on the upper side of the guide sleeve second, and the second pillar is disposed on the upper side of the telescopic rod second. Each of the first and second pillars has a T-shaped insertion groove on one side, into which a breathable nonwoven fabric plate first is inserted. Each of the first pillars has an L-shaped insertion groove on one side, into which a breathable nonwoven fabric plate second is inserted. The upper sides of the first and second pillars are snap-connected with a breathable nonwoven fabric plate third.

[0019] Through the above technical solution, the non-woven breathable protective component achieves assembly and protection functions with the telescopic frame through column support and plug / snap connection: One column is fixed to the upper side of the guide sleeve two, and the second column is fixed to the upper side of the telescopic rod two. The spacing is adjusted synchronously with the extension and retraction of the telescopic frame to form a vertical support frame around the tree crown. T-shaped insertion slots are opened on the same side of column one and column two. The breathable non-woven fabric board one is inserted along the opening direction of the T-shaped slot to realize the rapid assembly of the side protection layer. At the same time, an L-shaped insertion slot is opened on the other side of column one. The breathable non-woven fabric board two is pushed in sequentially along the horizontal and vertical directions of the L-shaped slot to fill the blind spot of the side protection and form a complete side windproof and heat insulation layer. The tops of columns one and two are equipped with a snap-fit ​​structure, which inserts the edge snaps of the breathable non-woven fabric board three into the slots at the top of the columns, completing the assembly of the top protective layer and ultimately forming a fully wrapped non-woven protective space on the sides and top. Breathable non-woven fabric panels one, two, and three all use breathable non-woven fabric material. While blocking cold air from entering, they allow for moderate exchange of air between the inside and outside of the cover, preventing excessive humidity inside the cover from causing mold growth on branches or carbon dioxide accumulation from affecting the respiration of fruit trees.

[0020] Using a plug-in and snap-on connection method, there is no need to use needle and thread to sew or glue to stick. Growers can quickly complete the assembly and disassembly of non-woven fabric boards, which is especially suitable for emergency protection operations in spring and autumn, reducing labor costs. Breathable non-woven fabric material not only meets the needs of windproof and heat preservation, but also avoids the problem of high humidity inside the cover caused by complete sealing, preventing fruit tree branches from becoming moldy and flower buds from rotting, and ensuring the normal physiological activities of fruit trees. If a non-woven fabric panel is damaged due to wear or tear, only the corresponding panel needs to be removed or the buckle released for replacement, without replacing the entire protective assembly, thus reducing maintenance costs. At the same time, the lightweight non-woven fabric material will not put excessive load on the telescopic frame, avoiding deformation caused by excessive load. After disassembly, the non-woven fabric panel can be folded for storage, and the column volume decreases as the telescopic frame retracts, resulting in a small overall storage space, which is convenient for warehouse storage during off-seasons and reduces storage costs.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through bidirectional telescopic adjustment of telescopic rod one and guide sleeve one and telescopic rod two and guide sleeve two, eliminates the need to customize protective devices for fruit trees of different heights and crown widths, and can flexibly adapt to various fruit tree specifications, reducing the equipment procurement costs for growers. The symmetrical structure of the telescopic frame ensures that the non-woven breathable protective components evenly cover the tree canopy, forming a complete protective space, effectively isolating the cold wind from the outside, reducing the frost damage to fruit tree branches and flower buds caused by low temperatures, and avoiding the problem of branches breaking due to strong winds. The sliding connection structure of the guide sleeve and telescopic rod does not need to be permanently fixed. It can be adjusted again later according to the growth of the fruit trees, such as when the canopy widens, or it can be disassembled and stored during non-windproof and heat-insulating seasons, such as summer, to avoid aging and wear caused by long-term exposure of the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-3 This utility model provides a technical solution: A detachable windproof and heat-insulating cover for fruit tree canopies includes two parallel and symmetrically arranged telescopic frames, and a non-woven breathable protective component covering the upper side of the telescopic frames.

[0027] Each telescopic frame includes a guide sleeve 1. The guide sleeve 1 has a sliding hole 1 inside, and a telescopic rod 2 is slidably connected in the sliding hole 1, so that the telescopic rod 2 can extend and retract relative to the guide sleeve 1, thereby adjusting the length dimension of the telescopic frame.

[0028] On the same side of both guide sleeve 1 and telescopic rod 2, a guide sleeve 2 is fixedly installed. The two guide sleeves 2 3 are arranged coaxially. Each guide sleeve 2 3 has a sliding hole 2 inside, and a telescopic rod 2 4 is slidably connected in the sliding hole 2. The two telescopic rods 2 4 can extend and retract relative to their corresponding guide sleeves 2 3, thereby adjusting the telescopic frame in another direction. Through the coordinated adjustment of telescopic rod 1 2 and telescopic rod 2 4, the frame formed by the two telescopic frames can flexibly adapt to fruit tree canopies of different sizes and shapes.

[0029] To securely fix the entire insulation cover to the ground, a side plate 5 is fixedly installed at the outer ends of each of the two guide sleeves 1 and the two telescopic rods 2. A ground anchor 6 is installed on one side of each side plate 5. By inserting or nailing the ground anchor 6 into the ground, the entire support structure can be firmly anchored.

[0030] To enhance the overall stability between the two telescopic frames and lock their relative positions after adjustment, a connecting plate 7 is installed between the opposing ends of the two telescopic rods 4. A fastening bolt 8 is rotatably connected to one side of the connecting plate 7 via a bearing or similar structure. One end of the fastening bolt 8 passes through the connecting plate 7 and is threaded onto the end side wall of one of the telescopic rods 4. Rotating the fastening bolt 8 can pull or push the two telescopic rods 4, thereby fine-tuning the distance between the two telescopic frames and ultimately locking their relative positions through the tightening force of the bolt.

[0031] To secure the telescopic rod 24 to any extended position within the guide sleeve 23, a locking bolt 9 is threaded through the upper side of the guide sleeve 23. After the telescopic rod 24 is adjusted to the appropriate length, the locking bolt 9 is tightened so that its lower end is in close contact with the surface of the telescopic rod 24, using friction to prevent the telescopic rod 24 from sliding, thus achieving one-way locking.

[0032] The non-woven breathable protective assembly features a modular design, facilitating installation, disassembly, and partial replacement. It primarily consists of breathable non-woven fabric panels for covering the top and sides.

[0033] Specifically, several columns 10 are fixedly installed on the upper side of the guide sleeve 2 3. Several columns 2 11 are fixedly installed on the upper side of the telescopic rod 2 4. The columns 10 and 2 11 together form the skeleton supporting the covering material.

[0034] For the side coverage area, both uprights 10 and 11 have vertical T-shaped insertion slots 12 on their opposite sides. Correspondingly, a breathable non-woven fabric board 13 is provided, with T-shaped inserts that fit the T-shaped insertion slots 12 fixed to its edges. The side insulation panel can be quickly installed by inserting the inserts from top to bottom into the slots.

[0035] For the portion covering the end face, a vertical L-shaped insertion groove 14 is provided on one side of the end post 10. Correspondingly, a breathable non-woven fabric board 15 is provided, with an L-shaped insert strip that matches the L-shaped insertion groove 14 fixed to its edge. Installation is also completed by insertion.

[0036] For the portion covering the top surface, a breathable non-woven fabric panel 316 is installed. The four corners or edges of the breathable non-woven fabric panel 316 are equipped with buckles or straps, which can be directly fastened or tied to the top of the posts 10 and 21, thereby sealing the top of the tree canopy.

[0037] Erecting the support structure: Based on the size of the fruit tree canopy, pull the telescopic rod 2 and the telescopic rod 4 respectively to initially adjust the frame size formed by the two telescopic frames. Tighten the locking bolt 9 on the guide sleeve 3 to fix the length of the telescopic rod 4. Then, by rotating the fastening bolt 8 on the connecting plate 7, fine-tune the final distance between the two telescopic frames and lock them in place.

[0038] The workflow of this embodiment is as follows: Fixed support: Cover the entire support with the outside of the fruit tree canopy and fix the support firmly to the ground by the ground anchors 6 under the side plate 5.

[0039] Install the protective cover: Insert the breathable non-woven fabric board 13 into the T-shaped insertion slot 12 of the side column in sequence, insert the breathable non-woven fabric board 2 15 into the L-shaped insertion slot 14 of the end column, and finally cover the top with the breathable non-woven fabric board 3 16 and fix it with buckles.

[0040] Disassembly and Storage: After the windproof and heat-insulating season, disassemble each non-woven fabric board in reverse order, loosen the ground anchor 6 and various locking bolts, and shrink the bracket to its minimum volume for easy storage.

[0041] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
