Description

Technical Field

[0001] This utility model relates to a fruit tree antifreeze and heat preservation cover, specifically a reusable fruit tree antifreeze and heat preservation cover, belonging to the technical field of fruit tree antifreeze and heat preservation covers. Background Technology

[0002] In the field of agricultural production, fruit trees, as important economic crops, are extremely sensitive to environmental temperature during their growth process. Especially under severe weather conditions such as low winter temperatures and late spring frosts, the branches, trunks, and flower buds of fruit trees are easily damaged by frost, leading to reduced fruit yields, decreased quality, and in severe cases, even death of the fruit trees, causing huge economic losses to fruit farmers. Therefore, fruit tree anti-frost insulation covers, as a convenient and efficient anti-frost tool, have been widely promoted and applied in fruit-growing areas due to their advantages of being able to be quickly erected, effectively blocking the invasion of external low temperatures, and creating a relatively stable and warm microenvironment for fruit trees.

[0003] However, most existing fruit tree frost protection and insulation covers have various problems. For example, in a fruit tree frost protection and insulation device disclosed in announcement number CN218389002U, although the first and second insulation devices can be quickly fixed with bolts and can also be quickly disassembled, the volume of the cover is fixed in this technical solution and in most current insulation covers. It cannot be flexibly adjusted according to the thickness of the tree. Specifically, the dimensions and specifications of existing reusable fruit tree frost protection and insulation covers are pre-set during production. Parameters such as diameter, height, and circumference are all fixed values. In actual use, fruit farmers need to purchase insulation covers of the corresponding specifications according to the approximate thickness of their fruit trees. However, fruit tree growth has obvious individual differences. Even fruit trees of the same variety and age will have significantly different trunk thicknesses under different growing environments. At the same time, the trunk thickness of fruit trees will change year by year at different growth stages.

[0004] The fixed size design flaw of this type of cover causes numerous inconveniences for fruit farmers and seriously affects the frost protection and insulation effect. On the one hand, if the insulation cover purchased by the fruit farmer is too large, a large gap will be formed between the cover and the trunk when it is placed on a thinner fruit tree. Cold air from the outside can easily enter the cover through the gap, disrupting the warm environment inside and causing a significant reduction in the frost protection and insulation effect, failing to effectively protect the fruit tree from frost damage. On the other hand, if the insulation cover purchased is too small, it is not only difficult to operate during the installation process, requiring the insulation cover to be forcibly pulled to be placed on a thicker fruit tree, but it may also cause the insulation cover to tear or break, shortening its service life and increasing the fruit farmer's usage costs. In addition, for orchards with fruit trees of varying thicknesses, fruit farmers need to purchase multiple insulation covers of different sizes, which not only increases the complexity of the procurement process, but may also lead to resource waste due to improper size matching. Utility Model Content

[0005] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing a reusable fruit tree antifreeze and heat preservation cover.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reusable fruit tree antifreeze and heat preservation cover includes a support rod, a sliding cylinder and a linkage heat preservation component. The sliding cylinder is slidably sleeved on the outside of the support rod, and multiple support rods and sliding cylinders are equidistantly arranged in the overall structure and are combined to form a polygonal structure. The linkage heat preservation component is connected to the support rod.

[0008] The linkage insulation component includes a linkage component and an insulation component. The linkage component includes a first linkage rod and a second linkage rod, which are rotatably connected at their centers. One end of the first linkage rod and the second linkage rod are rotatably connected to two adjacent sliding cylinders, and the other end is rotatably connected to the bottom of a support rod. The linkage component is located between two adjacent support rods, but no linkage component is located between two of the support rods. The insulation component includes an antifreeze insulation cloth, which is fixed between two adjacent support rods.

[0009] As a further improvement of this utility model, the linkage insulation component also includes driven rods. Two driven rods are provided between two adjacent support rods, and one end of the two driven rods is rotatably connected to each other, while the other end is rotatably connected to the top of the two adjacent support rods respectively.

[0010] As a further improvement of this utility model: a screw hole is provided on the outer wall of the sliding cylinder, the screw hole is linked with the inside of the sliding cylinder, and a locking screw is provided in the screw hole, one end of the locking screw abutting against the support rod.

[0011] As a further embodiment of this utility model: both the upper and lower ends of the support rod are provided with mating holes, the mating holes are provided with threads, and a mating rod is provided between the upper and lower support rods. The upper and lower ends of the mating rod are coaxially fixed with connecting screws, and the connecting screws are threaded into the mating holes.

[0012] As a further improvement of this utility model: the antifreeze insulation cloth is made of elastic material, and a cotton insulation layer is set inside the antifreeze insulation cloth. The ends of the antifreeze insulation cloth are fixed with straps, and the antifreeze insulation cloth is detachably connected to the support rod through the straps.

[0013] As a further improvement of this utility model: both the upper and lower ends of the support rod are coaxially fixed with limit cylinders, and the sliding cylinder is located between the upper and lower limit cylinders.

[0014] The beneficial effects of this utility model are:

[0015] In this invention, a sliding cylinder slides outside the support rod, forming a cylindrical structure with multiple equidistant support rods and sliding cylinders. The overall diameter can be adjusted according to the thickness of the fruit tree. When the sliding cylinder slides on the support rod, the first and second linkage rods in the linkage insulation component, whose ends are rotatably connected to the sliding cylinder and support rod respectively, deform accordingly, causing the antifreeze insulation cloth to expand and contract synchronously. This allows for flexible adjustment of the insulation cover's volume, adapting to fruit trees of different thicknesses. The antifreeze insulation cloth is positioned between adjacent support rods. With the adjustment of the linkage structure, the antifreeze insulation cloth can tightly fit fruit trees of different thicknesses, reducing gaps between it and the trunk, effectively blocking cold air from entering, providing a good insulation and protection environment for the fruit tree, and improving the antifreeze effect. The volume adjustment of the insulation cover can be achieved simply by sliding the sliding cylinder, without the need for complex disassembly or splicing processes. Operation is simple, allowing a single fruit farmer to quickly complete the installation work on different fruit trees, reducing labor intensity and improving work efficiency.

[0022] 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.

[0023] Example 1

[0024] like Figures 1 to 5 As shown, a reusable fruit tree antifreeze and heat preservation cover includes a support rod 1, a sliding cylinder 2 and a linkage heat preservation component. The sliding cylinder 2 is slidably sleeved on the outside of the support rod 1, and multiple support rods 1 and sliding cylinders 2 are equidistantly arranged in the overall structure and are combined to form a polygonal structure. The linkage heat preservation component is connected to the support rod 1.

[0025] The linkage insulation component includes a linkage component and an insulation component. The linkage component includes a first linkage rod 3 and a second linkage rod 4. The first linkage rod 3 and the second linkage rod 4 are rotatably connected at their centers. One end of the first linkage rod 3 and the second linkage rod 4 are rotatably connected to two adjacent sliding cylinders 2, and the other end is rotatably connected to the bottom of the support rod 1. The linkage component is set between two adjacent support rods 1, and no linkage component is set between two of the support rods 1. The insulation component includes an antifreeze insulation cloth 5, which is fixed between two adjacent support rods 1.

[0026] The linkage insulation component also includes driven rods 6. There are two driven rods 6 between two adjacent support rods 1, and one end of the two driven rods 6 is rotatably connected to each other, while the other end is rotatably connected to the top of the two adjacent support rods 1 respectively.

[0027] In this invention, the sliding cylinder 2 slides outside the support rod 1. Combined with multiple equidistant support rods 1 and sliding cylinders 2 forming a cylindrical structure, the overall diameter can be adjusted according to the thickness of the fruit tree. When the sliding cylinder 2 slides on the support rod 1, the first linkage rod 3 and the second linkage rod 4 in the linkage insulation component, whose ends are respectively rotatably connected to the sliding cylinder 2 and the support rod 1, will deform accordingly, causing the antifreeze insulation cloth 5 to expand and contract synchronously. This allows for flexible adjustment of the insulation cover's volume, adapting to fruit trees of different thicknesses. The antifreeze insulation cloth 5 is positioned between two adjacent support rods 1. With the adjustment of the linkage structure, the antifreeze insulation cloth 5 can tightly fit fruit trees of different thicknesses, reducing gaps between it and the trunk, effectively blocking cold air from entering, providing a good insulation and protection environment for the fruit tree, and improving the antifreeze effect. The volume adjustment of the insulation cover can be achieved simply by sliding the sliding cylinder 2, without the need for complex disassembly or splicing processes. Operation is simple, allowing a single fruit farmer to quickly complete the installation work on different fruit trees, reducing labor intensity and improving work efficiency.

[0028] Example 2

[0029] like Figures 1 to 5 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0030] The outer wall of the sliding cylinder 2 is provided with a screw hole, which is linked to the inside of the sliding cylinder 2. A locking screw 7 is provided in the screw hole, and one end of the locking screw 7 abuts against the support rod 1. When the sliding cylinder 2 is slidably adjusted to a suitable position, the locking screw 7 is tightened so that one end abuts against the support rod 1, which can firmly lock the sliding cylinder 2 on the support rod 1, preventing the sliding cylinder 2 from accidentally sliding due to external force or environmental factors during use, ensuring the stability of the volume of the heat preservation cover after adjustment, and ensuring the heat preservation effect.

[0031] Both ends of the support rod 1 are provided with mating holes 8, and threads are provided in the mating holes 8. A mating rod 9 is provided between the two support rods 1. The upper and lower ends of the mating rod 9 are coaxially fixed with connecting screws 10. The connecting screws 10 are threaded into the mating holes 8. Through the connection screws 10 fixed coaxially at the upper and lower ends of the mating rod 9 and the threaded engagement with the mating holes 8, the upper and lower support rods 1 can be quickly connected and disassembled. This design allows the heat preservation cover to be flexibly adjusted according to the height of the fruit trees, adapting to fruit trees of different heights. At the same time, it facilitates the disassembly and storage of the heat preservation cover when not in use, saving storage space and making it easy to transport and carry.

[0032] The antifreeze insulation cloth 5 is made of elastic material and has a cotton insulation layer inside. The ends of the antifreeze insulation cloth 5 are fixed with straps 51. The antifreeze insulation cloth 5 is detachably connected to the support rod 1 through the straps 51, so that it can better expand and contract with the linkage structure and fit tightly to fruit trees of different thicknesses. The cotton insulation layer inside uses the good heat insulation properties of cotton to further enhance the heat insulation effect of the antifreeze insulation cloth 5, effectively reduce heat loss inside the cover, provide a warmer protective environment for fruit trees, and resist low temperature damage.

[0033] The upper and lower ends of the support rod 1 are coaxially fixed with limit cylinders 11. The sliding cylinder 2 is located between the upper and lower limit cylinders 11. The limit cylinders 11 limit the sliding cylinder 2 to prevent it from slipping off the support rod 1.

[0034] When using this fruit tree anti-freezing and heat preservation cover, first unfold the entire structure of the support rod 1, and remove the anti-freezing and heat preservation cloth 5 between two adjacent support rods 1 that do not have a linkage component. Then, through this notch, put the entire heat preservation cover on the fruit tree. At this time, the sliding cylinder 2 is located between the upper and lower limiting cylinders 11 and can slide freely along the axial direction of the support rod 1. Then, according to the thickness of the fruit tree trunk, slide the sliding cylinder 2. Since the sliding cylinder 2 is rotatably connected to the first linkage rod 3 and the second linkage rod 4, and the other end of the first linkage rod 3 and the second linkage rod 4 is connected to the bottom of the support rod 1... The sliding cylinder 2 rotates and slides, which causes the first linkage rod 3 and the second linkage rod 4 to deform in conjunction. At the same time, the driven rod 6 between the two adjacent support rods 1 also moves in coordination, causing the antifreeze insulation cloth 5 to expand and contract accordingly, tightly fitting the trunk of the fruit tree. After the antifreeze insulation cloth 5 is adjusted to the appropriate position and tightly wraps the fruit tree, tighten the locking screw 7 in the screw hole on the outer wall of the sliding cylinder 2 so that one end abuts against the support rod 1, and firmly lock the sliding cylinder 2. Finally, the antifreeze insulation cloth 5 at the notch position is then tied and fixed to the support rod 1 at the corresponding position by the binding strap 51.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
