Description

Technical Field

[0001] This application relates to the field of tree sun protection, and in particular to a sun-scalding device for the trunks of trees that are not sun-resistant. Background Technology

[0002] Trees that are not tolerant of direct sunlight, such as horse chestnuts, usually prefer shade or are shade-tolerant in their sapling stage. They are not suitable for prolonged exposure to strong sunlight, otherwise they may experience poor growth. Although they like sunlight, they are not tolerant of strong sunlight or western exposure, otherwise it is easy to cause trunk scorching. Severe scorching can easily lead to fungal infections, thus affecting survival.

[0003] The trunk of this tree is sensitive to heat and sun exposure, especially in the summer when it is prone to peeling and flaking. To protect the trunk from these issues and reduce peeling after exposure to high temperatures or sunlight, a sunscald protection device for sun-sensitive trees has been designed. This device, through the splicing of an arc-shaped support plate, an arc-shaped edging plate, and an arc-shaped inner plate, creates a tubular protective structure on the trunk surface. This reduces direct sunlight exposure to the trunk, effectively protecting the tree trunk and minimizing peeling and flaking after exposure to high temperatures or sunlight. Utility Model Content

[0004] In order to solve the existing technical problems, this application provides a sun-scalding device for the trunks of trees that are not resistant to sun exposure.

[0005] This application provides a sunscald prevention device for the trunks of trees that are not resistant to sun exposure, employing the following technical solution: A sunscald prevention device for the trunks of trees that are not resistant to sun exposure includes an arc-shaped support plate disposed on the surface of the tree. Arc-shaped edging plates are rotatably connected to both sides of the arc-shaped support plate. Arc-shaped inner plates are slidably connected to the inner cavities of the two arc-shaped edging plates. Multiple U-shaped positioning heads are welded to the surfaces of the two arc-shaped inner plates. Hollow connecting parts are rotatably connected to the inner cavities of the U-shaped positioning heads. Vertical hole connecting parts are rotatably connected to the inner cavities of the U-shaped positioning heads. Rectangular positioning heads are slidably connected to the upper and lower sides of the inner cavities of the vertical hole connecting parts. A spring is welded between the two rectangular positioning heads. Limit frames are welded to the upper and lower sides of the inner cavities of the hollow connecting parts. The surfaces of the rectangular positioning heads are slidably connected to the inner cavities of the limit frames.

[0006] By adopting the above technical solution, two arc-shaped support plates are placed on the surface of the tree trunk. Then, the two arc-shaped edging plates are flipped over, and the two arc-shaped inner plates are pulled to slide within the cavities of the arc-shaped edging plates. This makes the arc-shaped inner plates fit the surface shape of the tree trunk more closely. Then, the positions of the hollow connector and the vertical hole connector are aligned, and the hollow connector and the vertical hole connector are rotated to adjust their angles. This ensures that the vertical hole connector can slide into the cavity of the hollow connector and is fixedly connected to it. This fixes the position of the two arc-shaped support plates, thus creating a tubular protective structure on the surface of the tree trunk. This can cover and protect the tree trunk, reducing direct sunlight exposure and minimizing peeling or flaking of the bark after high temperatures or sun exposure.

[0007] Preferably, the hollow connector is located on the left side of the arc-shaped support plate.

[0008] Preferably, the vertical hole connector is located on the right side of the arc-shaped support plate.

[0009] Preferably, the hollow connector has raised frames welded to both the upper and lower sides, and the inner cavity of the raised frames is connected to the inner cavity of the limiting frame.

[0010] Preferably, the inner cavity of the raised frame is slidably connected to a rectangular abutment block, and the front side of the inner cavity of the hollow connector is provided with a guide arc surface.

[0011] Preferably, the surface of the rectangular positioning head is provided with an arc surface, and the surface of the arc surface is slidably connected to the inner cavity of the guide arc surface.

[0012] Preferably, ventilation holes are opened on the surface of both the arc-shaped edging plate and the arc-shaped inner plate, and rubber edging is fixedly connected to the upper and lower sides of the inner cavity of the arc-shaped edging plate.

[0013] By adopting the above technical solution and setting ventilation holes, the tree trunk surface can be protected from the sun by the cooperation of two arc-shaped support plates, while avoiding the situation where the tree trunk surface would be stuffy and hot due to the sealing of the arc-shaped edging plate and the arc-shaped inner plate.

[0014] Preferably, a telescopic rod is welded between the rectangular positioning heads, and the surface of the telescopic rod is slidably connected to the inner cavity of the spring.

[0015] By adopting the above technical solution and setting the telescopic rod, the two rectangular positioning heads can be guided and limited by a vertical force during the sliding process of the two rectangular positioning heads in the inner cavity of the vertical hole connector, which can prevent the rectangular positioning heads from tilting during relative sliding.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. This utility model involves placing two arc-shaped support plates on the surface of a tree trunk, then flipping two arc-shaped edging plates and sliding two arc-shaped inner plates within the cavities of the edging plates. This allows the arc-shaped inner plates to better conform to the shape of the tree trunk. The hollow connector and the vertical hole connector are then aligned and rotated to adjust their angles, ensuring the vertical hole connector can slide into the cavity of the hollow connector and be fixedly connected to it. This fixes the two arc-shaped support plates in place, creating a tubular protective structure on the tree trunk surface. This protects the trunk by reducing direct sunlight exposure and minimizing peeling or flaking of the bark after exposure to high temperatures or sunlight.

[0018] 2. By incorporating ventilation holes, this utility model, in conjunction with two arc-shaped support plates, can provide sun protection to the tree trunk surface while preventing the trunk surface from becoming stuffy and hot due to the sealing effect of the arc-shaped edging plate and the arc-shaped inner plate.

[0019] 3. By setting up a telescopic rod, this utility model allows the two rectangular positioning heads to receive a vertical guiding and limiting force during the sliding process within the cavity of the vertical hole connector, thus preventing the rectangular positioning heads from tilting during relative sliding.

[0027] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. Example 1

[0028] Combination Figure 1-6 This application discloses a sunscald prevention device for the trunk of a tree that is not resistant to sun exposure. It includes an arc-shaped support plate 2 disposed on the surface of the tree 1. Arc-shaped edging plates 3 are rotatably connected to both sides of the arc-shaped support plate 2. Arc-shaped inner plates 4 are slidably connected to the inner cavities of both arc-shaped edging plates 3. Multiple U-shaped positioning heads 5 are welded to the surfaces of both arc-shaped inner plates 4. Hollow connecting parts 6 are rotatably connected to the inner cavities of the U-shaped positioning heads 5, located on the left side of the arc-shaped support plate 2. Vertical hole connecting parts 7 are rotatably connected to the inner cavities of the U-shaped positioning heads 5, located on the right side of the arc-shaped support plate 2. Rectangular positioning heads 8 are slidably connected to the upper and lower sides of the inner cavities of the vertical hole connecting parts 7. A spring 9 is welded between two rectangular positioning heads 8. A spring 9 is welded to the upper and lower sides of the inner cavities of the hollow connecting parts 6. The surface of the rectangular positioning head 8 is slidably connected to the inner cavity of the limiting frame 10. The upper and lower sides of the hollow connector 6 are welded with the raised frame 11. The inner cavity of the raised frame 11 is connected to the inner cavity of the limiting frame 10. The inner cavity of the raised frame 11 is slidably connected with the rectangular abutment block 12. The front side of the inner cavity of the hollow connector 6 is provided with the guide arc surface 13. The surface of the two rectangular positioning heads 8 is provided with the arc surface 14. The surface of the arc surface 14 is slidably connected to the inner cavity of the guide arc surface 13. The surfaces of the arc-shaped edging plate 3 and the arc-shaped inner plate 4 are provided with ventilation holes 15. With the setting of the ventilation holes 15, the tree trunk surface can be protected from the sun with the cooperation of the two arc-shaped support plates 2, while avoiding the situation of the tree trunk surface being stuffy due to the sealing of the arc-shaped edging plate 3 and the arc-shaped inner plate 4. Example 2

[0029] Combination Figure 2 , Figure 3 and Figure 5Rubber edging 16 is fixedly connected to both the upper and lower sides of the inner cavity of the arc-shaped edging plate 3. A telescopic rod 17 is welded between the two rectangular positioning heads 8. The surface of the telescopic rod 17 is slidably connected to the inner cavity of the spring 9. By setting the telescopic rod 17, the two rectangular positioning heads 8 can be guided and limited vertically during the sliding process in the inner cavity of the vertical hole connector 7, which can prevent the rectangular positioning heads 8 from tilting when sliding relative to each other.

[0030] Working Principle: When using this invention, the user places two arc-shaped support plates 2 on the surface of the tree trunk, then flips the two arc-shaped edging plates 3 and pulls the two arc-shaped inner plates 4 to slide within the cavities of the arc-shaped edging plates 3, thereby making the arc-shaped inner plates 4 more conform to the surface shape of the tree trunk. Then, the hollow connector 6 and the vertical hole connector 7 are aligned, and the hollow connector 6 and the vertical hole connector 7 are rotated to adjust their angles, ensuring that the vertical hole connector 7 can slide into the cavity of the hollow connector 6. Before the vertical hole connector 7 slides into the cavity of the hollow connector 6, the rectangular positioning head 8 will be positioned on its surface arc 14 and the hollow connector... Under the action of the inner guide arc surface 13 of the connector 6, the two rectangular positioning heads 8 are squeezed into the inner cavity of the vertical hole connector 7. When the position of the rectangular positioning head 8 slides to the position of the limiting frame 10, the rebound force of the spring 9 resets the rectangular positioning head 8 and makes the rectangular positioning head 8 slide into the inner cavity of the limiting frame 10. Then, the vertical hole connector 7 and the hollow connector 6 are fixedly connected, and the two arc-shaped support plates 2 are fixed in position. This gives the surface of the trunk a tubular protective structure, which can cover and protect the trunk of the plant to reduce the direct sunlight on the surface of the trunk and reduce the peeling or flaking of the bark after high temperature or sun exposure.

[0031] In summary, this sunscald protection device for tree trunks susceptible to sunburn works by placing two arc-shaped support plates 2 on the surface of the trunk, then flipping two arc-shaped edging plates 3 and sliding two arc-shaped inner plates 4 within the cavities of the edging plates 3. This allows the inner plates 4 to better conform to the shape of the trunk surface. Next, the hollow connector 6 and the vertical hole connector 7 are aligned, and their angles are adjusted by rotating them. This ensures that the vertical hole connector 7 can slide into the cavity of the hollow connector 6 and is fixedly connected to it. This fixes the position of the two arc-shaped support plates 2, creating a tubular protective structure on the trunk surface. This effectively protects the tree trunk from direct sunlight, reducing the risk of peeling or flaking of the bark after exposure to high temperatures or direct sunlight.

[0032] Experiment 1: Horse Chestnut Sunburn Prevention Experiment

[0033] The sunscald prevention device used in this experiment was applied to the construction project of the Bahekou flood storage and detention area in Chaoyang District, Beijing. During the vegetation restoration and reconstruction along the riverbanks, vegetation was established in early March 2024. Large arbor projects (Aesculus hippocastanum) were transplanted to both sides of the river. In the experimental group, each Aesculus hippocastanum trunk was secured with the sunscald prevention device. In the control group, the trunks were only secured with a sealing gasket (inner layer) and an arc-shaped edging plate (outer layer). The control group received no protection. The main study focused on the effects of different sunscald prevention methods on bark peeling of Aesculus hippocastanum trunks. Specifically, a 1-square-decimeter quadrat was taken from the same location (sun-facing side) on the same plot of land. Peeling was calculated per square decimeter in August and December, with three replicates for each treatment, and the average value was taken.

[0036] Experimental Results: Table 1 shows that the trunks of horse chestnuts are prone to peeling or shedding bark, which severely affects their transplant survival rate. The sunscald prevention structure of this application significantly alleviates the problem of bark peeling. Under high summer temperatures and high solar radiation, the experimental group showed improved bark peeling, with significantly lower peeling in both the transverse and longitudinal directions compared to the control and blank groups. Furthermore, the study indicates that ventilation is a crucial factor affecting bark peeling in horse chestnut trees, in addition to high temperature and solar radiation. This application, combined with the trunk sunscald prevention device, incorporates ventilation holes in the edge-sealing plate, effectively mitigating the increased surface temperature and obstructed air exchange in the bark stomata under high-temperature radiation. Comparing the experimental and control groups, the bark peeling rate in the control group was significantly higher than in the experimental group, especially in the longitudinal direction. The device of this application can prevent peeling while also effectively reducing longitudinal cracking. Trees intolerant of high temperatures and strong solar radiation also suffer severe sunscald in winter. This is because the bark cracking that occurs in summer is repeatedly triggered by winter solar radiation, causing further cracking and peeling in the same locations. The more frequent the cracking, the greater the longitudinal peeling. Comparisons using the sunscald prevention device of this application show superior performance in both longitudinal cracking and peeling in winter observations of transplanted tree trunks.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
