Description

Technical Field

[0001] The present invention relates to the technical field of tree protection equipment, and particularly to a protection device for the base of the trunk of standing trees for forest tending. Background Art

[0002] Forest tending refers to the process of taking certain technical means to improve the forest structure, enhance the forest ecological function, and improve the forest productivity during the growth process of the forest. In order to ensure the sustainable development of the forest and prevent the trees from being damaged during the tending process, especially the protection of the base area of the tree trunk is particularly important. The damage to the base of the trunk of standing trees often affects the growth and development of the trees, and even leads to the spread of pests and diseases and slow growth. Therefore, the effective protection of the base of the trunk of standing trees is an important link in forest tending.

[0003] During the protection process, the protection device is one of the indispensable equipment. Most of the existing protection devices on the market cannot ensure that they can be flexibly adjusted at different growth stages of the trees and always keep close contact with the tree trunk, so as to provide continuous and effective protection. For this reason, a protection device for the base of the trunk of standing trees for forest tending is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a protection device for the base of the trunk of standing trees for forest tending.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A protection device for the base of the trunk of standing trees for forest tending, including a protection unit and an auxiliary unit. The auxiliary unit is installed on the upper end surface of the protection unit. The protection unit includes a protection cylinder and a base inserted into the inner cavity of the protection cylinder. An installation mechanism is inserted and arranged at the interval between the two protection cylinders. A support mechanism is horizontally arranged in the inner cavity of the installation mechanism. It includes a protection cylinder body and an inner insertion cavity opened at the top position of the protection cylinder body. An insertion groove is opened on the outer end surface of the protection cylinder body. An object placement box is inserted into the inner cavity of the insertion groove. The auxiliary unit is arranged at the top of the protection cylinder.

[0007] Preferably, the installation mechanism includes an installation part and a plug-in part installed at the interval between the two installation parts. A hollow hole is opened in the middle position of the plug-in part. A side end part is installed on the outer end surface of the installation part. The other end of the side end part is provided with a horizontal cylinder.

[0008] Preferably, the support mechanism includes an inner cylinder and an insertion cylinder opened at the top of the inner cylinder. An adaptation cylinder is opened at the top position of the insertion cylinder. The outer end surface of the adaptation cylinder is connected to an insertion cross cylinder through a series belt. External rods are horizontally arranged on both sides of the outer end surface of the insertion cross cylinder. The other ends of the external rods are installed with adaptation rods. The intervals between the two groups of adaptation rods are connected in series through clamping rods. Limiting inner rods are horizontally arranged on the inner sides of the outer end surfaces of the adaptation rods. The overall device is divided into four groups and unfolded. One of the structures is vertically inserted into one side of the tree trunk to be protected with the base as the bottom, so that the installation mechanism and the support mechanism are inwardly attached to the outer wall of the tree trunk. If the outer bark of the tree trunk to be protected is intact and when the tree grows, the inner bark will be forced to expand as the tree trunk expands. As the cells expand, the phloem will become soft, thus supporting the growth of the tree. At this time, the protected outer bark is in a state of soft inside and hard outside. The contact structure formed by the adaptation rods and the clamping rods can deform according to the outer wall structure of the outer bark until the contact surface of the adaptation rods and the clamping rods completely fits the outer bark, so as to achieve the protection effect on the tree trunk.

[0009] The device is vertically inserted into one side of the tree trunk with the base as the bottom, and can accurately fit the shape of the tree trunk. As the tree grows, the tree trunk gradually expands, and the inner bark expands accordingly. The design of the device can flexibly adapt to this change. Especially through the contact structure formed by the adaptation rods and the clamping rods, it can deform as the tree trunk expands, ensuring that the protection device always fits the outer wall of the tree trunk. It fully considers the natural process of tree growth, does not limit the normal development of the tree, protects the tree trunk, and does not cause too much pressure on the growth of the tree.

[0010] Due to the variability of the device structure, when the outer bark of the tree trunk is intact, the device can adjust according to the shape of the outer wall of the bark through the adaptive deformation formed by the contact surface of the adaptation rods and the clamping rods, ensuring that the contact surface completely fits the outer bark. This design method enables the outer bark to be better protected and avoids damage to the bark caused by external factors such as mechanical damage and animal gnawing.

[0011] The outer bark is in a state of "soft inside and hard outside". As the tree grows, the phloem becomes soft and the tree can expand itself. The deformation characteristics of the protection device can provide flexible support and protection with the change of the tree trunk. Through this unique protection mechanism, the device does not interfere with the natural growth process of the tree. Especially during the growth process of the tree, the device can adapt to the change of the tree trunk diameter and prevent the device from hindering the growth of the tree. Therefore, the device can not only provide effective protection but also ensure the normal growth of the tree.

[0012] As the tree grows, the outer bark gradually changes. The protection device maintains close contact with the tree trunk through adaptive deformation, provides long-term and stable protection, and avoids damage to the base of the tree trunk by the external environment.

[0013] By setting the limiting inner rod to limit the deformation structure formed by the adapting rod and the clamping rod, it can effectively prevent the adapting rod and the clamping rod from being overly bent, resulting in excessive deformation angle of the device. This design ensures that the device can adaptively deform during the growth of the tree trunk, but will not affect the stability of the overall structure due to excessive deformation. The limiting inner rod provides reasonable limitation, avoiding the device from being unable to effectively protect the tree due to excessive bending, and ensuring that it can provide appropriate support and protection at different stages of the tree growth.

[0014] If the outer bark of the protected tree falls off, and even the inner bark or secondary xylem is exposed to the environment, the device can still provide effective protection by the outer end walls of the adapting rod and the clamping rod fitting on the outer surface of the tree trunk. Even if the bark falls off, the device can still form a protective layer around the outside of the tree trunk, preventing the inner bark or secondary xylem from being directly exposed to the external environment, and preventing external factors such as insect pests, diseases, and mechanical damage from causing further damage to the tree. It ensures that when the tree encounters adverse environments such as outer bark falling off, the device can still play a protective role, thus avoiding more serious damage to the base of the tree.

[0015] Preferably, the storage box includes a box body and baffles installed at the edge positions of the inner end surface of the box body. Communication holes are opened on both sides of the surface of the baffles. An adapting mechanism is arranged on one side of the inner cavity wall of the box body, and a surrounding mechanism is arranged on one side of the adapting mechanism.

[0016] Preferably, the adapting mechanism includes adapting blocks and protruding blocks installed on the side end surfaces of the adapting blocks. A linkage member is installed at the interval between the two groups of adapting blocks. The surrounding mechanism includes positioning members and shaft rods installed on the inner end surfaces of the positioning members. A surrounding cylinder is arranged at the interval between the two groups of relatively arranged shaft rods. When it is necessary to fix the whole tree trunk, the hemp rope is wound around the outer ring of the surrounding cylinder, and the hemp rope can effectively fix the tree trunk at the required position. This method of surrounding and fixing ensures that the hemp rope tightly wraps the tree trunk, avoiding the tree trunk from being displaced or tilted due to the influence of external wind force or other factors. Through the fastening of the hemp rope, the tree trunk is firmly fixed, avoiding the deviation or instability of the tree trunk position, thus providing a solid support for the tree.

[0017] Taking the surrounding cylinder as a fulcrum, rotating between the shaft rod and the positioning member ensures that the angle of the fixing structure can be flexibly adjusted, enabling the hemp rope and the fixing device to adapt to the shape and angle changes of the tree trunk. By rotating the fulcrum shaft rod and the positioning member, the device can be accurately adjusted according to the different sizes and bark forms of the trees, improving the adaptability and flexibility of the fixing device, enhancing the adaptability of the device, and ensuring that the fixing system can adapt to the changes of the trees at different growth stages without affecting the effect of the device due to the growth of the trees.

[0018] Preferably, an auxiliary unit is installed on the upper end surface of the base. The auxiliary unit includes an inner support mechanism and a clamping mechanism installed at the top of the inner support mechanism. The inner support mechanism includes an installation vertical rod and a top rod installed at the upper end of the installation vertical rod. An empty hole is penetrated through one end of the top rod, and a top piece is installed at the top position of the top rod. Through holes are opened on both sides of the outer end face edge of the empty hole.

[0019] Preferably, the top rod vertically penetrates into the inner cavity of the hollow hole, so that the protection unit and the auxiliary unit are combined into a whole. A clamping mechanism is installed on the upper end surface of the top piece. The clamping mechanism includes an upper installation rod and an installation key installed at one end of the upper installation rod. The outer end face of the installation key fits against the outer end face of the wrapping ring, and an inner contact ring is opened on the inner end face of the wrapping ring.

[0020] Preferably, the four wrapping rings are combined into an annular structure, and the end points of adjacent inner contact rings are in contact with each other. When the whole support mechanism supports the tree trunk, through the guidance of the hemp rope and the cooperation of the fixing structure, the protection and stability of the tree trunk are further enhanced. The guidance of the hemp rope enables each group of fixing structures to closely fit the tree trunk, providing uniform pressure during the whole support process and preventing the tree trunk from shifting or being subjected to excessive concentrated pressure.

[0021] The hemp rope penetrates through the inner cavity of the empty hole or the through hole, making the connection between the overall devices closer and ensuring the linkage between the four groups of fixing structures and other components. Through the penetration of the hemp rope, the whole protection device forms a more stable and coordinated system, avoiding loosening or imbalance of each part and improving the overall stability of the device. The penetration connection of the hemp rope inside the device strengthens the connection between components, ensuring that every part of the tree can be comprehensively protected.

[0022] After the four groups of fixing structures are fixed, through the support of the upper installation rod and the installation key, the upper half part of the outer wall of the tree trunk is effectively supported. This design ensures that during different growth stages of the tree, the outer wall can obtain a uniform pressure distribution, avoiding tearing of the bark or uneven stress on the tree trunk. The supporting effect of the wrapping ring improves the stability of the overall device on the tree trunk and prevents external forces from affecting the normal growth of the tree. The supporting effect helps the tree to remain stable during natural disasters such as strong winds and heavy rains and is not easily damaged by external factors.

[0023] The inner contact ring in the supporting state wraps the outer wall of the tree trunk from outside to inside, further enhancing the protection of the tree trunk. This design effectively prevents the direct influence of the external environment such as sunlight exposure and moisture erosion on the tree trunk. Especially when the bark is damaged or the tree encounters external pressure, it can provide an additional protective layer. The wrapping design not only enables the outer wall of the tree trunk to be stably supported but also avoids external mechanical damage, such as damage caused by animal gnawing and sandstorms.

[0024] The four sets of wrapping rings are tied with hemp rope after fixing, which increases the stability of the whole device. This tying effect can be adjusted by the extra length of hemp rope to ensure that the four sets of fixing structures fit the tree trunk evenly, so that every part of the tree trunk is effectively protected. The fixing of hemp rope not only enhances the stability of the device, but also effectively disperses the points of external force, avoiding excessive pressure on a certain part, which helps to maintain the healthy growth of trees for a long time.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. Adaptive protection of tree trunk growth: The device is inserted vertically into the trunk through the base and can accurately fit the trunk shape. As the tree grows, the trunk gradually expands and the inner bark expands. The device design can flexibly adapt to this change, especially through the contact structure of the adapter rod and the clamping rod, which can deform as the trunk expands, ensuring that the device always fits the outer wall of the trunk. This ensures the normal growth of the tree without causing excessive pressure on the tree, while providing effective protection for the tree.

[0027] 2. Protection of soft bark inside and hard outside: The bark is in a state of "soft inside and hard outside". The device design can adapt to the expansion of the trunk through the deformation characteristics of the adapter rod and the clamping rod, providing effective protection to prevent the bark and trunk from being damaged by external factors such as mechanical damage, animal gnawing, etc.

[0028] 3. Deformation limit function: By setting the limit inner rod, the adapter rod and the clamping rod are prevented from excessively bending, which may cause the device to deform too much. This design ensures that the device can deform adaptively during the growth of the tree trunk, but will not affect the structural stability due to excessive deformation, ensuring that proper support and protection are provided for a long time.

[0029] 4. Rotational stability: The interlaced horizontal cylinder is inserted into the inner cavity of the horizontal cylinder through transverse penetration, and forms a linkage effect with the series belt, which can rotate around the adapter cylinder, so that the device can be fine-tuned according to the changes of the tree, always maintaining contact with the outer wall of the trunk, and enhancing the adaptability and stability of the device.

[0030] 5. Protection function when the tree bark falls off: If the outer bark of the tree falls off, or even the inner bark or secondary wood is exposed, the device can still fit the outer surface of the trunk through the outer end wall of the adapter rod and the clamping rod to form an effective protective layer. This ensures that the inner bark and secondary wood are not harmed by the external environment (such as insect pests, pathogens, mechanical damage, etc.), and prevents the base of the tree from further damage.

[0031] 6. Fixing function of hemp rope: The hemp rope winds around the outer circle of the cylinder and then around the tree trunk, ensuring that the tree trunk is fixed in the required position and preventing the position or stability of the tree trunk from being affected by external wind or other factors. The tightening effect of the hemp rope firmly fixes the tree trunk, provides solid support, and prevents the tree trunk from shifting or becoming unstable. Rotating around the cylinder as a fulcrum between the shaft rod and the positioning member, the device can adapt to the morphological and angular changes of the tree trunk, improving the adaptability and flexibility of the fixing device. The design of the rotating fulcrum ensures that the device can be precisely adjusted according to the different sizes and bark morphologies of trees.

[0032] 7. Evenly distribute pressure: Supported by the mounting rod and the mounting key, the upper half of the outer wall of the tree trunk is effectively supported, ensuring that the outer wall of the tree trunk is evenly stressed and preventing the bark from being torn or the tree trunk from being unevenly stressed. The wrapping ring and the inner contact ring wrap the outer wall of the tree trunk from outside to inside, further enhancing the protection of the tree trunk.

[0033] 8. Prevent the influence of the external environment: The wrapping design effectively prevents the direct influence of external environments such as sunlight exposure and moisture erosion on the tree trunk. Especially when the bark is damaged or the tree encounters external pressure, it provides an additional protective layer to avoid external mechanical damage (such as animal gnawing, sand and dust, etc.).

[0034] 9. Tight connection of four groups of fixing structures: The hemp rope is tied between the four groups of fixing structures to ensure that the fixing structures evenly fit the tree trunk and effectively disperse the external force, preventing a certain part from bearing too much pressure. Through the adjustment of the hemp rope, the stability of the overall device is enhanced, and the healthy growth of the tree can be maintained for a long time. Description of the Drawings

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0046] Refer to Figures 1-9, Embodiment 1, A protection device for the base of a standing tree trunk used for forest tending, comprising a protection unit 1 and an auxiliary unit 2. The auxiliary unit 2 is installed on the upper end face of the protection unit 1. The protection unit 1 includes a protection cylinder 11 and a base 12 inserted into the inner cavity of the protection cylinder 11. An installation mechanism 13 is inserted and arranged at the interval between the two protection cylinders 11. A support mechanism 14 is horizontally arranged in the inner cavity of the installation mechanism 13. The 11 includes a protection cylinder body 111 and an inner insertion cavity 112 opened at the top position of the protection cylinder body 111. An insertion groove 113 is opened on the outer end face of the protection cylinder body 111. A storage box 15 is inserted into the inner cavity of the insertion groove 113. The auxiliary unit 2 is arranged at the top of the protection cylinder 11.

[0047] The installation mechanism 13 includes an installation part 131 and a plug-in part 132 installed at the interval between the two installation parts 131. A hollow hole 133 is opened at the middle position of the plug-in part 132. A side end part 134 is installed on the outer end face of the installation part 131. A horizontal cylinder 135 is arranged at the other end of the side end part 134.

[0048] The support mechanism 14 includes an inner cylinder 141 and an insertion cylinder 142 opened at the top of the inner cylinder 141. An adaptation cylinder 143 is opened at the top position of the insertion cylinder 142. The outer end face of the adaptation cylinder 143 is connected to an insertion horizontal cylinder 145 through a series belt 144. External connection rods 146 are horizontally arranged on both sides of the outer end face of the insertion horizontal cylinder 145. An adaptation rod 147 is installed at the other end of the external connection rod 146. The interval between the two adaptation rods 147 is connected in series through a clamping rod 148. A limiting inner rod 149 is horizontally arranged on the inner side of the outer end face of the adaptation rod 147. The whole device is divided into four groups and unfolded. One of the groups of structures is vertically inserted into one side of the tree trunk to be protected with the base 12 as the bottom, so that the installation mechanism 13 and the support mechanism 14 are inwardly attached to the outer wall of the tree trunk. If the outer bark of the tree trunk of the protected tree is intact, and when the tree grows, the inner bark will be forced to expand as the trunk expands. As the cells expand, the phloem will become soft, thus supporting the growth of the tree. At this time, the protected outer bark is in a state of being soft inside and hard outside. The contact structure formed by the adaptation rod 147 and the clamping rod 148 can deform according to the outer wall structure of the outer bark until the contact surface of the adaptation rod 147 and the clamping rod 148 is completely attached to the outer bark, so as to achieve the protection effect on the tree trunk.

[0049] Example 2: The device is vertically inserted into one side of the tree trunk through the base 12 as the bottom, and can accurately fit the shape of the tree trunk. As the tree grows, the trunk gradually expands, and the inner bark expands accordingly. The design of the device can flexibly adapt to this change. In particular, the contact structure formed by the adapter rod 147 and the clamping rod 148 can deform with the expansion of the tree trunk, ensuring that the protection device always fits the outer wall of the tree trunk. It fully considers the natural process of tree growth, does not limit the normal development of the tree, protects the tree trunk, and does not cause excessive pressure on the growth of the tree.

[0050] Example 3: Due to the variability of the device structure, when the outer bark of the tree trunk is intact, the device can adjust according to the shape of the outer bark through the adaptive deformation formed by the contact surface of the adapter rod 147 and the clamping rod 148, ensuring that the contact surface completely fits the outer bark. This design method provides better protection for the outer bark and avoids damage to the bark caused by external factors such as mechanical damage and animal gnawing.

[0051] Example 4: The outer bark is in a state of "soft inside and hard outside". As the tree grows, the phloem softens, and the tree can expand itself. The deformation characteristics of the protection device can provide flexible support and protection with the change of the tree trunk. Through this unique protection mechanism, the device does not interfere with the natural growth process of the tree. Especially during the growth process of the tree, the device can adapt to the change of the tree trunk diameter and prevent the device from hindering the growth of the tree. Therefore, the device can not only provide effective protection but also ensure the normal growth of the tree;

[0052] As the tree grows, the outer bark gradually changes. The protection device maintains close contact with the tree trunk through self-adaptive deformation, providing long-term and stable protection to avoid damage to the base of the tree trunk from the external environment.

[0053] Example 5: By setting the limit inner rod 149 to limit the deformation structure formed by the adapter rod 147 and the clamping rod 148, it can effectively prevent the adapter rod 147 and the clamping rod 148 from being overly bent, resulting in excessive deformation angles of the device. This design ensures that the device can adaptively deform during the growth of the tree trunk, but will not affect the stability of the overall structure due to excessive deformation. The limit inner rod 149 provides reasonable limitation to avoid the device being unable to effectively protect the tree due to excessive bending, ensuring that it can provide appropriate support and protection at different stages of tree growth.

[0054] Example 6. If the outer bark of the protected tree falls off and even the inner bark or secondary xylem is exposed to the environment, the device can still provide effective protection by fitting the outer end walls of the adapter rod 147 and the clamping rod 148 to the outer surface of the tree trunk. Even if the bark falls off, the device can still form a protective layer around the outside of the tree trunk, preventing the inner bark or secondary xylem from being directly exposed to the external environment and protecting against further damage to the tree caused by external factors such as pests, pathogens, and mechanical damage. This ensures that when the tree encounters adverse environments such as outer bark shedding, the device can still play a protective role, thereby avoiding more serious damage to the base of the tree.

[0055] Example 7. The storage box 15 includes a box body 151 and a baffle 152 installed at the edge position of the inner end face of the box body 151. Communication holes 153 are opened on both sides of the surface of the baffle 152. An adaptation mechanism 154 is provided on one side of the inner cavity wall of the box body 151, and a surrounding mechanism 155 is provided on one side of the adaptation mechanism 154.

[0056] The adaptation mechanism 154 includes an adaptation block 1541 and a protruding block 1542 installed on the side end face of the adaptation block 1541. A linkage member 1543 is installed at the interval between the two groups of adaptation blocks 1541. The surrounding mechanism 155 includes a positioning member 1551 and a shaft rod 1552 installed on the inner end face of the positioning member 1551. A surrounding cylinder 1553 is provided at the interval between the two groups of shaft rods 1552 arranged oppositely. When it is necessary to fix the entire tree trunk, a hemp rope is wound around the outer circle of the surrounding cylinder 1553. The hemp rope can effectively fix the tree trunk in the required position. This surrounding and fixing method ensures that the hemp rope tightly wraps the tree trunk, preventing the tree trunk from shifting or tilting due to the influence of external wind or other factors. Through the fastening of the hemp rope, the tree trunk is firmly fixed, avoiding the deviation or instability of the tree trunk position, thereby providing a solid support for the tree.

[0057] Rotating between the shaft rod 1552 and the positioning member 1551 with the surrounding cylinder 1553 as the fulcrum ensures that the angle of the fixing structure can be flexibly adjusted, enabling the hemp rope and the fixing device to adapt to the shape and angle changes of the tree trunk. By rotating the fulcrum shaft rod 1552 and the positioning member 1551, the device can be precisely adjusted according to the different sizes and bark morphologies of the trees, improving the adaptability and flexibility of the fixing device, enhancing the adaptability of the device, and ensuring that the fixing system can adapt to the changes of the tree in different growth stages without affecting the effect of the device due to the growth of the tree.

[0058] Embodiment 8. An auxiliary unit 2 is installed on the upper end face of the base 12. The auxiliary unit 2 includes an inner support mechanism 21 and a clamping mechanism 22 installed at the top of the inner support mechanism 21. The inner support mechanism 21 includes an installation vertical rod 211 and a top rod 212 installed at the upper end of the installation vertical rod 211. One end of the top rod 212 is provided with a hollow hole 213 in an inserted manner. A top piece 214 is installed at the top position of the top rod 212. Through holes 215 are opened on both sides of the outer end face edge of the hollow hole 213. The top rod 212 vertically penetrates into the inner cavity of the hollow hole 133, so that the protection unit 1 and the auxiliary unit 2 are combined into a whole.

[0059] The clamping mechanism 22 is installed on the upper end face of the top piece 214. The clamping mechanism 22 includes an upper installation rod 221 and an installation key 222 installed at one end of the upper installation rod 221. The outer end face of the installation key 222 is attached to the outer end face of the wrapping ring 223. An inner contact ring 224 is opened on the inner end face of the wrapping ring 223.

[0060] The four groups of the wrapping rings 223 are combined into an annular structure. The end points of the adjacent inner contact rings 224 are in contact with each other. When the whole support mechanism 14 supports the tree trunk, through the guidance of the hemp rope and the cooperation of the fixing structure, the protection and stability of the tree trunk are further enhanced. The guidance of the hemp rope enables each group of fixing structures to be closely attached to the tree trunk, providing uniform pressure during the whole support process and preventing the tree trunk from shifting or being subjected to excessive concentrated pressure.

[0061] The hemp rope penetrates through the inner cavity of the hollow hole 213 or the through hole 215, making the connection between the whole devices closer, ensuring the linkage between the four groups of fixing structures and other components. Through the penetration effect of the hemp rope, the whole protection device forms a more stable and coordinated system, avoiding loosening or imbalance of each part, improving the overall stability of the device. The penetration connection of the hemp rope inside the device strengthens the connection between components, ensuring that every part of the tree can be comprehensively protected.

[0062] Embodiment 9. After the four groups of fixing structures are fixed, through the support of the upper installation rod 221 and the installation key 222, the upper half part of the outer wall of the tree trunk is effectively supported. This design ensures that during different growth stages of the tree, the outer wall can obtain a uniform pressure distribution, avoiding tearing of the bark or uneven stress on the tree trunk. The supporting effect of the wrapping ring 223 improves the stability of the whole device on the tree trunk, preventing external forces from affecting the normal growth of the tree. The supporting effect helps the tree to remain stable in natural disasters such as strong winds and heavy rains and is not easily damaged by external factors.

[0063] Example 10: The inner contact ring 224 in the supporting state wraps the outer wall of the tree trunk from outside to inside, further enhancing the protection of the tree trunk. This design effectively prevents the direct impact of the external environment such as sunlight exposure and moisture erosion on the tree trunk. Especially when the bark is damaged or the tree encounters external pressure, it can provide an additional protective layer. The wrapping design not only provides stable support for the outer wall of the tree trunk but also avoids external mechanical damage, such as damage caused by animal gnawing and sand and wind.

[0064] Example 11: Between the four groups of wrapping rings 223, binding is carried out with the hemp rope after fixation, increasing the stability of the overall device. This binding effect can be adjusted through the excess length of the hemp rope to ensure that the four groups of fixing structures fit evenly against the tree trunk, enabling effective protection of every part of the tree trunk. The fixation of the hemp rope not only enhances the stability of the device but also effectively disperses the acting points of external forces, avoiding excessive pressure on a certain part and contributing to the long-term healthy growth of the tree.

[0065] In summary: The overall device is divided into four groups for deployment. One group of the structure is vertically inserted into one side of the tree trunk to be protected with the base 12 as the bottom, so that the installation mechanism 13 and the support mechanism 14 fit inward against the outer wall of the tree trunk. If the outer bark of the tree trunk to be protected is intact and when the tree grows, the inner bark will be forced to expand as the tree trunk expands. As the cells expand, the phloem will soften to support the growth of the tree. At this time, the protected outer bark is in a state of being hard outside and soft inside. The contact structure formed by the adapter rod 147 and the clamping rod 148 can deform according to the outer wall structure of the outer bark until the contact surface of the adapter rod 147 and the clamping rod 148 completely fits against the outer bark, thus achieving the protection effect on the tree trunk;

[0066] The device is vertically inserted into one side of the tree trunk with the base 12 as the bottom, and can accurately fit the shape of the tree trunk. As the tree grows, the tree trunk gradually expands, and the inner bark expands accordingly. The design of the device can flexibly adapt to this change. Especially through the contact structure formed by the adapter rod 147 and the clamping rod 148, it can deform as the tree trunk expands, ensuring that the protection device always fits against the outer wall of the tree trunk. It fully considers the natural process of tree growth and will not limit the normal development of the tree. It not only protects the tree trunk but also does not cause excessive pressure on the growth of the tree;

[0067] Due to the variability of the device structure, when the outer bark of the tree trunk is intact, the device can adjust according to the shape of the bark outer wall through the adaptive deformation formed by the contact surface of the adapter rod 147 and the clamping rod 148, ensuring that the contact surface completely fits against the outer bark. This design method provides better protection for the outer bark and avoids damage to the bark caused by external factors such as mechanical damage and animal gnawing;

[0068] The outer bark is "soft inside and hard outside". As the tree grows, the phloem becomes soft and the tree can expand itself. The deformation characteristics of the protection device can provide flexible support and protection as the trunk changes. Through this unique protection mechanism, the device will not interfere with the natural growth process of the tree. In particular, during the growth of the tree, the device can adapt to the changes in the trunk diameter to prevent the device from hindering the growth of the tree. Therefore, the device can provide effective protection and ensure the normal growth of the tree.

[0069] As the tree grows, the outer bark gradually changes. The protective device maintains close contact with the trunk through adaptive deformation, providing long-term and stable protection to prevent the base of the trunk from being damaged by the external environment. By setting the limiting inner rod 149, the deformation structure formed by the adapter rod 147 and the clamping rod 148 is limited, which can effectively prevent the adapter rod 147 and the clamping rod 148 from deforming too much due to excessive bending. This design ensures that the device can adaptively deform during the growth of the trunk, but will not affect the stability of the overall structure due to excessive deformation. The limiting inner rod 149 provides a reasonable limit to prevent the device from being unable to effectively protect the tree due to excessive bending, ensuring that it can provide appropriate support and protection at different stages of tree growth;

[0070] The interlaced horizontal cylinder 145 is inserted into the inner cavity of the horizontal cylinder 135 by horizontal penetration, and forms a linkage with the series belt 144, so that the interlaced horizontal cylinder 145 can rotate with the outer end wall of the adapter cylinder 143 as a fulcrum. This design improves the rotation stability of the device, so that the interlaced horizontal cylinder 145 and the external rod 146 can rotate around the horizontal cylinder 135 as a fulcrum. This rotation mechanism allows the device to flexibly adjust the angle during the growth of the tree, ensuring that the interlaced horizontal cylinder 145 and the external rod 146 can accurately adapt to the changes in the tree trunk, enhancing the contact surface between the device and the trunk, thereby improving the protection effect;

[0071] Since the interlaced horizontal cylinder 145 and the external rod 146 can rotate at an angle using the horizontal cylinder 135 as a fulcrum, the device can be fine-tuned according to the growth of the tree, ensuring that the protection device always maintains proper contact with the outer wall of the trunk, and will not fall off or be too close to the trunk due to excessive deformation. The rotating structure makes the shape of the device more flexible, which can adapt to the natural expansion of the trunk and provide more precise protection;

[0072] If the outer bark of the protected tree falls off and even the inner bark or secondary xylem is exposed to the environment, the device can still provide effective protection by fitting the outer end walls of the adapter rod 147 and the clamping rod 148 to the outer surface of the tree trunk. Even if the bark falls off, the device can still form a protective layer around the outside of the tree trunk, preventing the inner bark or secondary xylem from being directly exposed to the external environment and protecting against further damage to the tree caused by external factors such as pests, diseases, and mechanical damage. This ensures that when the tree encounters adverse environments such as outer bark shedding, the device can still play a protective role, thus avoiding more serious damage to the base of the tree;

[0073] When the whole tree trunk needs to be fixed, the hemp rope is wound around the outer circle of the winding cylinder 1553, and the hemp rope can effectively fix the tree trunk in the required position. This winding and fixing method ensures that the hemp rope tightly wraps the tree trunk, preventing the tree trunk from shifting or tilting due to the influence of external wind or other factors. Through the tightening of the hemp rope, the tree trunk is firmly fixed, avoiding the deviation or instability of the tree trunk position, thus providing a solid support for the tree;

[0074] Rotating between the shaft rod 1552 and the positioning member 1551 with the winding cylinder 1553 as the fulcrum ensures that the angle of the fixing structure can be flexibly adjusted, enabling the hemp rope and the fixing device to adapt to the shape and angle changes of the tree trunk. By rotating the fulcrum shaft rod 1552 and the positioning member 1551, the device can be precisely adjusted according to the different sizes and bark forms of the trees, improving the adaptability and flexibility of the fixing device, enhancing the adaptability of the device, and ensuring that the fixing system can adapt to the changes of the tree at different growth stages without being affected by the development of the tree;

[0075] When the entire support mechanism 14 supports the tree trunk, through the cooperation of the hemp rope guidance and the fixing structure, the protection and stability of the tree trunk are further enhanced. The guidance of the hemp rope enables each group of fixing structures to closely fit the tree trunk, providing uniform pressure during the entire support process to prevent the tree trunk from shifting or being subjected to excessive concentrated pressure.

[0076] The hemp rope passes through the inner cavity of the hollow hole 213 or the through member 215, making the connection between the overall devices more compact and ensuring the linkage between the four groups of fixing structures and other components. Through the penetration of the hemp rope, the entire protection device forms a more stable and coordinated system, avoiding loosening or imbalance of each part, improving the overall stability of the device. The penetration connection of the hemp rope inside the device strengthens the connection between components, ensuring that every part of the tree can be comprehensively protected;

[0077] After the fixation of the four groups of fixing structures is completed, with the support of the upper mounting rod 221 and the mounting key 222, the upper half of the outer wall of the tree trunk is effectively supported. This design ensures that during different growth stages of the tree, the outer wall can obtain a uniform pressure distribution, avoiding the tearing of the bark or uneven stress on the tree trunk. The supporting effect of the wrapping ring 223 improves the overall stability of the device on the tree trunk and prevents external forces from affecting the normal growth of the tree. The supporting effect helps the tree maintain stability during natural disasters such as strong winds and heavy rains and is not easily damaged by external factors;

[0078] The inner contact ring 224 in the supporting state wraps the outer wall of the tree trunk from the outside to the inside, further enhancing the protection of the tree trunk. This design effectively prevents the direct impact of the external environment such as sun exposure and moisture erosion on the tree trunk. Especially when the bark is damaged or the tree encounters external pressure, it can provide an additional protective layer. The wrapping design not only enables the outer wall of the tree trunk to obtain stable support but also avoids external mechanical damage, such as damage caused by animal gnawing and sand and dust;

[0079] Between the four groups of wrapping rings 223, binding is carried out with the hemp rope after the fixation is completed, increasing the overall stability of the device. This binding effect can be adjusted through the length of the redundant hemp rope to ensure that the four groups of fixing structures fit the tree trunk evenly, enabling each part of the tree trunk to be effectively protected. The fixation of the hemp rope not only enhances the stability of the device but also effectively disperses the acting points of external forces, avoiding excessive pressure on a certain part and contributing to maintaining the healthy growth of the tree for a long time.
