Description

Technical Field

[0001] This invention relates to the field of tree protection, and more particularly to a method for repairing tree cavities in ancient trees. Background Technology

[0002] In nature, wood-decaying fungi can invade trees through wounds in the trunk, roots, and dead branches. Due to their advanced age and declining physiological functions, ancient trees are more prone to developing cavities of varying sizes and shapes in their trunks after years of fungal erosion. These cavities accelerate the weakening of ancient trees and reduce their mechanical strength, potentially leading to breakage and collapse under the loads of strong winds and snow. Currently, based on the size, location, and opening method of the cavities, there are two main restoration methods: cleaning and preservative treatment followed by opening, and cleaning and preservative treatment followed by sealing with a fluid gel-based solidified material.

[0003] When repairing tree cavities by sealing them with a viscous, hardened, anti-corrosion filling material, the filler needs to be injected into the cavity and then allowed to harden before the surface of the filler at the cavity opening is finished. However, it's crucial to prevent the filler from overflowing during injection. Currently, the common method is to manually block the opening with a baffle during injection. However, the location, shape, and form of the cavity opening make this difficult, affecting the repair's effectiveness and efficiency. Therefore, this solution proposes a new method for repairing ancient tree cavities. Summary of the Invention

[0004] The present invention proposes a method for repairing tree cavities in ancient trees, which solves the problem that existing methods of sealing tree cavities are inconvenient to cover the cavities when filling them with filler.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A method for restoring tree cavities in ancient trees includes the following steps:

[0007] S1. Clean the rotten and loose wood inside the tree cavity and measure the size of the cavity;

[0008] S2. Use a sanding machine to sand and clean the wood inside and around the tree hole that is still rotten but has a certain degree of hardness, and remove excess rotten parts.

[0009] S3. Spray the polished tree hole with a disinfectant to sterilize and kill insects.

[0010] S4. Gradually pour the filler into the tree cavity and wait for it to harden before sanding and finishing any parts protruding from the opening.

[0011] A device for restoring tree cavities in ancient trees, comprising:

[0012] A storage mechanism includes a hollow base and a mounting frame disposed at one end of the base. A battery is disposed inside the base, and the mounting frame has a U-shaped structure.

[0013] The transmission mechanism includes a fixed shaft rotatably connected to the inner wall of the bottom of the mounting frame, a mounting seat fixed to the top of the fixed shaft, a mounting plate fixed to the top surface of the mounting seat, a transmission rod one rotatably connected to the outer wall of one side of the mounting plate, a transmission rod two rotatably connected to the outer wall of the other side of the mounting plate, and a transmission motor mounted on the inner wall of the top of the mounting plate. The transmission motor cooperates with the transmission rod one and the transmission rod two.

[0014] A grinding mechanism includes a grinding head mounted on the other end of a drive rod and a dust collection assembly mounted on a mounting base. The dust collection assembly includes a collection box, a dust collection pipe mounted on the collection box, and an air suction component mounted on one side of the collection box. The air suction component is connected to the drive rod in a driving connection.

[0015] The injection mechanism includes a feeding cylinder fixed on a mounting plate, a pressure plate sleeved around the outer periphery of the feeding cylinder, an airbag sleeved around the outer periphery of the feeding cylinder, a limiting component sleeved around the outer periphery of the feeding cylinder to block the airbag, and an inflation component mounted on a mounting base. The airbag is located between the pressure plate and the limiting component. The pressure plate is made of flexible plastic. A spiral feeding shaft coaxially arranged inside the feeding cylinder is rotatably connected to it, and the spiral feeding shaft is driven by a second transmission rod. A feed pipe communicating with the outer periphery of the feeding cylinder is also installed thereon. The inflation component is driven by the second transmission rod and inflates the airbag and the limiting component under the drive of the second transmission rod.

[0016] An adjustment mechanism is installed at the bottom of the mounting frame and is used to drive the fixed shaft to rotate.

[0017] The above technical solution allows for convenient cleaning and filling of tree cavities. It not only effectively prevents the filling material from overflowing outside the tree cavity during filling, but also avoids sawdust flying around and obstructing the view when sanding the tree cavity.

[0018] As a further improvement to the above solution, the collection box is fixed to the outer periphery of the fixed shaft by a fixing rod. The inlet of the suction pipe is located below the grinding head and 3-4 cm behind the foremost end of the grinding head. The suction component includes a wind box fixed to the bottom surface of the mounting plate, a rotating shaft installed inside the wind box, a fan blade sleeved on the outer periphery of the rotating shaft, a connecting pipe installed on the outer wall of the wind box near the collection box, and a linkage rod 1 rotatably connected to the mounting base. The top of the linkage rod 1 extends above the mounting base and is connected to the transmission rod 1. One end of the rotating shaft extends to the outside of the wind box and is connected to the bottom of the transmission rod 1.

[0019] The above technical solution can drive the rotating shaft to rotate at the same time as the transmission rod rotates, thereby sucking the grinding debris into the collection box.

[0020] As a further improvement to the above solution, the bottom of the collection box is provided with a discharge hole, and a sealing plate for sealing the discharge hole is installed on the bottom surface of the collection box by screws. A through hole is provided at the connection between the collection box and the connecting pipe, and a filter screen is installed in the through hole. One end of the rotating shaft located inside the air box is fixed with a connecting shaft that is coaxial with it. The other end of the connecting shaft passes through the connecting pipe and the filter screen and extends to the inside of the collection box and is fixed with a scraper. One long side of the scraper abuts against the surface of the filter screen.

[0021] The above technical solution can scrape off the sketches adsorbed on the filter screen while the shaft is rotating, thus ensuring the air permeability of the filter screen.

[0022] As a further improvement to the above solution, the limiting component includes a fixed ring sleeved on the outer periphery of the feed cylinder and multiple telescopic tubes installed on the outer ring of the fixed ring. The fixed ring is connected to the airbag through a pipe, and a pressure relief valve is installed on the fixed ring. The multiple telescopic tubes are equidistantly distributed on the outer ring of the fixed ring.

[0023] The above technical solution can effectively prevent the airbag from expanding to the side away from the baffle after inflation.

[0024] As a further improvement to the above solution, the telescopic tube includes a fixed tube fixed to the outer periphery of the fixed ring, a movable tube sleeved on the outer periphery of the fixed tube, and an elastic element installed on the inner side of the fixed tube and the movable tube. The inner side of the movable tube is provided with a limiting groove arranged along its length direction. A limiting block is fixed to the outer periphery of the fixed tube. One end of the limiting block extends into the limiting groove and slides into the limiting groove. A limiting rod is fixed to the side of the movable tube near the airbag.

[0025] The above technical solution allows the telescopic tube to extend after inflation, thereby blocking the airbag from expanding away from the baffle. At the same time, the telescopic tube can also be shortened after inflation stops, so that the grinding mechanism will not be stuck when it is retracted into the mounting frame.

[0026] As a further improvement to the above solution, the elastic element includes a connecting block fixed to the inner ring of the fixed tube and a spring fixed to the connecting block, with the other end of the spring fixed to the inner wall of the movable tube.

[0027] The above technical solution allows the telescopic tube to automatically retract after inflation stops.

[0028] As a further improvement to the above solution, the inflation assembly includes a blower mounted on a mounting base and a second linkage rod rotatably connected to the mounting base. The top of the second linkage rod is connected to a second transmission rod, and the bottom of the second linkage rod is connected to the input end of the blower. The air outlet of the blower is fixedly connected to an air supply pipe that communicates with a fixed ring.

[0029] The above technical solution allows the blower to work simultaneously after the transmission rod rotates, thereby inflating the airbag and the fixed ring.

[0030] As a further improvement to the above solution, the adjustment mechanism includes a connecting gear rotatably connected to the bottom of the mounting frame via a connecting shaft, a rack disposed at the bottom of the mounting frame, a limiting frame movably sleeved on the outer periphery of the rack, and a connecting rod fixed to one end of the rack. The rack meshes with the connecting rod, the connecting shaft is coaxially arranged with the fixed shaft and fixedly connected to the bottom of the fixed shaft, the limiting frame is fixed to the bottom surface of the mounting frame, the bottom surface of the connecting rod is threaded with a positioning bolt, and the bottom surface of the mounting frame has two bolt holes that match the positioning bolts, and the two bolt holes are arranged along the length direction of the rack.

[0031] The above technical solution allows for the adjustment of the rotation of the fixed shaft by moving the connecting rod.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0033] 1. By setting up a sanding mechanism and a filling mechanism, the same equipment can be used to sand the tree cavity first and then fill it with filling material when repairing the tree cavity. This greatly facilitates the operation of technicians. At the same time, the dust collection component prevents wood chips from flying around and affecting the technicians' vision when sanding the tree cavity, and also effectively prevents dust from entering the technicians' eyes, mouth and nose.

[0034] 2. Through the cooperation between the transmission rod two, the limiting component, the airbag, the pressure plate, and the inflation component, air can be inflated into the airbag and the limiting component while the transmission rod two rotates. This causes the limiting component to open and the airbag to inflate accordingly. The limiting component prevents the airbag from expanding away from the pressure plate, thus allowing the airbag to be squeezed onto the pressure plate. In turn, the pressure plate is pressed tightly against the outer perimeter of the tree cavity, preventing the filling material from overflowing outside the tree cavity when filling.

[0035] 3. By adjusting the settings of the mechanism, the grinding mechanism and the injection mechanism can be easily interchanged, making it convenient for technicians to use them according to their needs. Attached Figure Description

Detailed Implementation

[0044] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example 1

[0045] Please combine Figure 1-6 This embodiment of an apparatus for repairing tree cavities in ancient trees includes:

[0046] The storage mechanism includes a hollow base 1 and a mounting frame 21 located at one end of the base 1. A battery is installed inside the base 1. The mounting frame 21 has a U-shaped structure. A pull ring 22 is fixed to the top surface of the mounting frame 21. A pull ring 23 is fixed to the end of the base 1 away from the mounting frame 21. The pull rings 22 and 23 facilitate technicians to carry the entire device in their hands during use. A PLC controller is also installed on the top surface of the mounting frame 21. The battery is connected to the PLC controller to ensure the normal operation of the PLC controller. An operation hole communicating with the interior is opened on one side of the outer wall of the base 1. The battery inside the base can be installed or removed through the operation hole. A cover plate 38 for sealing the operation hole is also installed on the outer wall of the base 1 with screws.

[0047] The transmission mechanism includes a fixed shaft 24 rotatably connected to the inner wall of the bottom of the mounting frame 21, a mounting base 3 fixed to the top of the fixed shaft 24, a mounting plate 26 fixed to the top surface of the mounting base 3, a transmission rod 2 on one side of the outer wall of the mounting plate 26, a transmission rod 27 on the other side of the outer wall of the mounting plate 26, and a transmission motor 7 mounted on the inner wall of the top of the mounting plate 21. One end of the output shaft of the transmission motor 7 is fixed with a driving bevel gear. A driven bevel gear 1 that matches the driving bevel gear is sleeved on the outer periphery of the transmission rod 2. A driven bevel gear 27 that meshes with the driving bevel gear is sleeved on the outer periphery of the transmission rod 27. When the driving bevel gear meshes with the driven bevel gear 1, it can drive the transmission rod 2 to rotate. When the driving bevel gear meshes with the driven bevel gear 2, it can drive the transmission rod 27 to rotate. The PLC controller is connected to the transmission motor 7, so that the start and stop of the transmission motor 7 can be controlled by the PLC controller.

[0048] The grinding mechanism includes a grinding head 4 mounted on the other end of a transmission rod 2 and a dust collection assembly mounted on a mounting base 3. The dust collection assembly includes a collection box 5, a dust collection pipe 6 mounted on the collection box 5, and an air suction component mounted on one side of the collection box 5. The air suction component is connected to the transmission rod 2. The collection box 5 is fixed to the outer periphery of a fixed shaft 24 by a fixing rod. The inlet of the dust collection pipe 6 is located below the grinding head 4 and 3-4 cm behind the foremost end of the grinding head. The air suction component includes a bellows 30 fixed to the bottom surface of the mounting plate 3, a rotating shaft 31 mounted inside the bellows 30, a fan blade 32 sleeved on the outer periphery of the rotating shaft 31, a connecting pipe 35 mounted on the outer wall of the bellows 30 near the collection box 5, and a linkage rod 25 rotatably connected to the mounting base 3. The top of the linkage rod 25 extends above the mounting base 3 and is connected to the transmission rod 2. One end of the rotating shaft 31 extends to the outside of the bellows 30 and is connected to the bottom of the transmission rod 2. A first linkage bevel gear is fitted onto the top of the first linkage rod 25, which extends above the mounting plate 3 and is fixed with a second linkage bevel gear that meshes with the first linkage bevel gear. When the grinding device is needed, it is placed on the outer front end of the mounting frame 21. At this time, the active bevel gear meshes with the driven bevel gear. After the drive motor 7 starts, it drives the drive rod 2 to rotate, which causes the grinding head 4 to rotate. At the same time, the rotation of the drive rod 2 also drives the linkage rod 25 to rotate, which causes the fan blade 32 to rotate. This allows the air in the collection box 5 to be drawn into the air box 30 and then discharged. This creates a negative pressure inside the collection box 5, allowing the debris generated by the grinding head 4 when grinding the tree hole to be sucked into the collection box 5 through the suction pipe 6. The suction pipe 6 is 3-4 cm behind the front end of the grinding head 4, which effectively prevents the suction pipe 6 from affecting the normal use of the grinding head 4 and prevents the suction pipe 6 from pressing against the inner wall of the tree hole when grinding the tree hole.

[0049] The filling mechanism includes a feeding cylinder 8 fixed to a mounting plate, a pressure plate 14 sleeved around the outer periphery of the feeding cylinder 8, an airbag 13 sleeved around the outer periphery of the feeding cylinder 8, a limiting component sleeved around the outer periphery of the feeding cylinder 8 to block the airbag 13, and an inflation component mounted on a mounting base 3. The airbag 13 is located between the pressure plate 14 and the limiting component. The pressure plate 14 is made of flexible plastic, which allows it to better fit the outside of the tree cavity, thus covering the tree cavity more tightly and preventing the filling material from leaking out when filling the tree cavity. A spiral feeding shaft is rotatably connected inside the feeding cylinder 8 and is coaxially arranged with it. The spiral feeding shaft is also connected to the transmission rod 27. A feed pipe 16 connected to the outer periphery of the feeding cylinder 8 is also installed therewith. The inflation component is connected to the transmission rod 27. 7. The transmission connection is driven by the transmission rod 27 to inflate the airbag 13 and the limiting assembly. The limiting assembly includes a fixed ring 15 sleeved on the outer circumference of the conveying cylinder 8 and multiple telescopic tubes installed on the outer ring of the fixed ring 15. The fixed ring 15 is connected to the airbag 13 through a pipe, and a pressure relief valve 36 is installed on the fixed ring 15. The multiple telescopic tubes are equidistantly distributed on the outer ring of the fixed ring 15. Each telescopic tube includes a fixed tube 9 fixed on the outer circumference of the fixed ring 15, a movable tube 10 sleeved on the outer circumference of the fixed tube 9, and elastic elements installed on the inner sides of the fixed tube 9 and the movable tube 10. A limiting groove 39 is provided on the inner side of the movable tube 10 along its length direction. A limiting block 40 is fixed on the outer circumference of the fixed tube 9. One end of the limiting block 40 extends into the limiting groove 39 and slides with the limiting groove 39. Connecting the movable tube 10, a limit rod 12 is fixed on the side near the airbag 13. The inflation assembly includes a blower 11 mounted on the mounting base 3 and a linkage rod 28 rotatably connected to the mounting base 3. The top of the linkage rod 28 is connected to the transmission rod 27, and the bottom of the linkage rod 28 is connected to the input end of the blower 11. The air outlet of the blower 11 is fixedly connected to an air supply pipe communicating with the fixed ring 15. When using the injection mechanism, the feeding cylinder 8 can be rotated to the outside of the opening of the mounting frame 21. At this time, the driving bevel gear and the driven bevel gear 2 mesh. Then, one end of the feeding cylinder 8 is inserted into the tree hole, and the baffle 14 covers the outside of the tree hole. Then, the transmission motor 7 is started. After the transmission motor 7 is started, it will drive the transmission rod 28 to the airbag 13. When the second movable rod 27 rotates, it drives the second linkage shaft 28 to rotate. The second linkage shaft 28 then rotates, causing the blower 11 to operate. This allows air to be pumped into the fixed tube 15 simultaneously with the rotation of the second movable rod 27. The gas filling the fixed tube 15 causes the movable tube 10 to extend away from the fixed ring 15. At the same time, air passes through the fixed ring 15 and enters the airbag 13, causing it to inflate. Due to the obstruction of multiple telescopic tubes, the inflated airbag 13 expands towards the pressure plate 14, thus pressing against it. Because the inflated airbag fits well against the surface of the pressure plate 14, the pressure plate 14 can conform to the curvature of the tree trunk.This ensures the tree hole is completely covered. The pressure plate 14, made of flexible plastic, allows for partial bending and folding when the filling mechanism is retracted into the mounting frame 21, guaranteeing its proper placement. When the pressure within the fixing ring 15 reaches the set pressure, the air inside can be released through the pressure relief valve 36. After the pressure plate 14 completely covers the tree hole, the filler is fed into the conveying cylinder 8 through the feed pipe 16. The rotating transmission rod 27 also drives the spiral conveying shaft, gradually transporting the filler from the conveying cylinder 8 into the tree hole.

[0050] The elastic element includes a connecting block 41 fixed to the inner ring of the fixed tube 9 and a spring 42 fixed to the connecting block 41. The other end of the spring 42 is fixed to the inner wall of the movable tube 10. When the movable tube 10 moves away from the fixed ring 15 by being inflated with air, the spring is in a stretched state. When the air supply to the fixed ring 15 stops, the movable ring 10 will automatically move closer to the fixed ring 15 under the action of the spring, thereby shortening the length of the telescopic tube. This prevents the injection mechanism from being stuck when it is housed inside the mounting frame 21.

[0051] An adjustment mechanism is installed at the bottom of the mounting frame 21 and is used to drive the fixed shaft to rotate. By driving the rotation of the fixed shaft, the positions of the injection mechanism and the grinding mechanism can be changed, so as to select whether to use the grinding mechanism or the injection mechanism as needed, which facilitates the use of technicians.

[0052] The implementation principle of this embodiment is as follows: Before repair, the tree hole is cleaned. After cleaning, the inner wall of the tree hole is polished using a polishing device. When using the polishing device, the polishing device is placed on the outer front end of the mounting frame 21. At this time, the active bevel gear and the driven bevel gear mesh. After the drive motor 7 is started, it drives the transmission rod 2 to start rotating, thereby causing the polishing head 4 to rotate. At the same time, the transmission rod 2 rotates, which also drives the linkage rod 25 to rotate, thereby causing the fan blade 32 to rotate. This allows the air in the collection box 5 to be sucked into the air box 30 and then discharged. The inside of the collection box 5 is thus formed by negative pressure, so that the debris generated by the polishing head 4 polishing the tree hole can be sucked into the collection box 5 through the suction pipe 6.

[0053] After the tree cavity is cleaned again after sanding, disinfectant and insecticide are sprayed before filling the tree cavity with filler. Before filling, the positions of the sanding mechanism and the filling mechanism are switched so that the filling mechanism is rotated to the outside of the front end of the mounting frame 21 and the sanding mechanism is retracted into the inside of the mounting frame 21.

[0054] When using the injection mechanism, the feeding cylinder 8 can be rotated to the outside of the opening of the mounting frame 21. At this time, the driving bevel gear and the driven bevel gear 2 mesh. Then, one end of the feeding cylinder 8 is inserted into the tree hole, and the baffle 14 covers the outside of the tree hole. Then, the drive motor 7 is started. After the drive motor 7 starts, it will drive the drive rod 27 to rotate. After the drive rod 27 rotates, it will drive the linkage shaft 28 to rotate. The linkage rod 28 starts to rotate. After the linkage rod 28 rotates, it drives the blower 11 to work. Thus, air can be injected into the fixed tube 15 while the drive rod 27 rotates. After the fixed tube 15 is filled with gas, the movable tube 10 extends away from the fixed ring 15. At the same time, air also enters through the fixed ring 15. The air is inserted into the airbag 13, causing it to inflate. Due to the obstruction of multiple telescopic tubes, the inflated airbag 13 expands towards the pressure plate 14, thus pressing against the pressure plate 14. Because the inflated airbag fits well against the surface of the pressure plate 14, the pressure plate 14 can conform to the curve of the tree trunk and fit against the tree trunk surface, thus covering the tree hole more tightly. When the pressure inside the fixing ring 15 reaches the set pressure, the air inside can be discharged through the pressure relief valve 36. After the pressure plate 14 has covered the tree hole tightly, the filler is fed into the conveying cylinder 8 through the feed pipe 16. The transmission rod 27 rotates while also driving the spiral conveying shaft to rotate, thus gradually conveying the filler in the conveying cylinder 8 into the tree hole. Example 2

[0055] Combination Figure 1-2 This embodiment is further improved on the basis of embodiment 1 as follows: the bottom of the collection box 5 is provided with a discharge hole, and a sealing plate 29 for sealing the discharge hole is installed on the bottom surface of the collection box 5 by screws. A through hole is provided at the connection between the collection box 5 and the connecting pipe 35. A filter screen 33 is installed in the through hole. One end of the rotating shaft 31 located in the air box 30 is fixed with a connecting shaft coaxially arranged therewith. The other end of the connecting shaft passes through the connecting pipe 35 and the filter screen 33 and extends to the inside of the collection box 5 and is fixed with a scraper 34. One long side of the scraper 34 abuts against the surface of the filter screen 33. The length of the scraper 34 is greater than the diameter of the filter screen 33. After opening the sealing plate 29, the sawdust collected in the collection box 5 can be discharged.

[0056] The implementation principle of this embodiment is as follows: when the transmission rod 2 rotates and drives the rotating shaft 31 to rotate, the scraper 34 also rotates synchronously with the rotating shaft 31, so as to scrape off the wood chips adsorbed on the filter screen 33, thereby ensuring that the wood chips have good passability. Example 3

[0057] Combination Figure 1 , Figure 3 and Figure 4This embodiment is further improved on the basis of embodiment 1 in that: the adjustment mechanism includes a connecting gear 18 rotatably connected to the bottom of the mounting frame 21 via a connecting shaft, a rack 17 set at the bottom of the mounting frame 21, a limiting frame movably sleeved on the outer periphery of the rack 17, and a connecting rod 19 fixed to one end of the rack 17. The rack 17 meshes with the connecting rod 19. The connecting shaft is coaxially arranged with the fixed shaft 24 and fixed to the bottom of the fixed shaft. The limiting frame is fixed to the bottom surface of the mounting frame 21. The bottom surface of the connecting rod 19 is threaded with a positioning bolt 20. The bottom surface of the mounting frame 21 has two bolt holes that match the positioning bolt 20, and the two bolt holes are arranged along the length direction of the rack 17. After the positioning bolt 20 is screwed into the bolt hole, the connecting rod 19 can no longer move, so that it will not rotate after being fixed when the grinding mechanism or the injection mechanism is working.

[0058] The implementation principle of this embodiment is as follows: when it is necessary to change the position of the grinding mechanism and the injection mechanism, the connecting rod 19 can be moved. After the connecting rod 19 moves, it drives the rack 17 to move, thereby driving the connecting gear 18 to rotate. After the connecting gear 18 rotates, it drives the fixed shaft 24 to rotate, thereby adjusting and changing the position of the grinding mechanism and the injection mechanism. Example 4

[0059] Combination Figure 1-6 This embodiment, based on Embodiment 1, further improves upon the following: the method for repairing tree cavities in ancient trees includes the following steps:

[0060] S1. Clean the rotten and loose wood inside the tree cavity, measure the size of the tree cavity, and calculate the amount of filling material needed.

[0061] S2. Use a sanding machine to sand and clean the wood inside and around the tree hole that still has a certain hardness and is decayed, remove excess decayed parts, thereby ensuring that all decayed material inside the tree hole is completely removed and that the inner wall of the tree hole is smooth, and clean out the debris left after sanding.

[0062] S3. Spray the sanded tree cavity with a disinfectant to kill pests and diseases, thereby ensuring that the tree trunk will not be harmed by residual wood-decaying fungi and pests, and thus ensuring its growth vitality.

[0063] S4. Gradually pour the filler into the tree cavity and wait for it to harden. Then, polish and trim any parts that protrude from the opening to prevent the filler from sticking out of the cavity and to ensure that it does not cover the bark at the opening. This allows the tree cavity to heal gradually during the recovery process.

[0064] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
