Description

Technical Field

[0001] This utility model relates to the field of tree antifreeze technology, specifically to a forestry tree antifreeze device. Background Technology

[0002] When winter comes, people need to take certain antifreeze measures for trees to prevent them from being damaged by frost.

[0003] According to application number CN202220848550.9, a novel anti-freezing device for forest trees is disclosed, including an anti-freezing sleeve. A first concave seat is fixedly connected to the bottom side of the anti-freezing sleeve. An adjusting rod is connected to the inner wall of the first concave seat through a rotating shaft. A fixed sleeve is slidably connected to the surface of the adjusting rod. The other end of the fixed sleeve is connected to a second concave seat through a rotating shaft.

[0004] The anti-freezing structure in the above case adopts a design where the support structure and the anti-freezing sleeve are integrally molded, and the two cannot be separated and replaced independently. On the one hand, when dealing with trees of different diameters, it is necessary to purchase a complete set of devices of the corresponding size. It is not possible to adapt to various types of trees by changing anti-freezing sleeves of different specifications, which leads to growers having to keep multiple sets of equipment, significantly increasing maintenance costs. On the other hand, as the trees grow year by year, the original integrated device will become unusable due to size limitations and must be discarded and replaced, resulting in a waste of resources and not meeting the actual needs of long-term maintenance. In addition, although some non-integrated devices can be adjusted in size, the anti-freezing sleeve cannot fully cover the tree after adjustment, reducing the anti-freezing effect. Therefore, we provide a forestry tree anti-freezing device. Utility Model Content

[0005] The purpose of this invention is to provide a frost protection device for forest trees to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a forest tree antifreeze device, comprising two annular blocks, an antifreeze sleeve provided on the inner wall of the annular blocks, the two annular blocks being connected by a fixed connection assembly for fixing the two annular blocks, and the annular blocks and the antifreeze sleeve being connected by a limiting disassembly assembly for disassembling the annular blocks from the antifreeze sleeve.

[0007] Optionally, the fixed connection assembly includes four fixing blocks, which are respectively installed on the front and back of two annular blocks. A bolt is provided on the fixing block on the left side. The right end of the bolt passes through the two fixing blocks from left to right and extends to their exterior. A fastening nut is threaded onto the surface of the bolt and on the fixing block on the right side.

[0008] Optionally, the limiting assembly includes slots and pull blocks. There are two slots, each located at the bottom of one of the two antifreeze sleeves on a side away from each other. There are two pull blocks, each located in a groove on one of the two annular blocks on a side away from each other.

[0009] Optionally, an insert block is installed on the inner wall of the annular block at the position corresponding to the slot. The side of the insert block near the slot penetrates the slot and extends into it to contact the inner wall of the slot. A locking block is installed on the side of the pull block near the slot. A locking groove is opened on the inner wall of the slot at the position corresponding to the locking block.

[0010] Optionally, two iron blocks are installed on the side of the pull block near the slot. A positioning groove is provided in the groove of the annular block and corresponding to the position of the iron blocks. The side of the iron block near the positioning groove passes through the positioning groove and extends into it to contact the inner wall of the positioning groove. A magnet that attracts the iron blocks is installed on the inner wall of the positioning groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model achieves independent disassembly and assembly of the annular block and the antifreeze sleeve through a limiting disassembly and assembly component. When dealing with trees of different diameters, there is no need to purchase the entire device. Only the antifreeze sleeve with the corresponding inner diameter specification needs to be replaced. The supporting structure such as the annular block, support frame, and insertion rod can be reused for a long time, reducing equipment storage costs. As the trees grow year by year, only the larger size antifreeze sleeve needs to be replaced. There is no need to discard the entire device, avoiding resource waste. It meets the actual needs of long-term dynamic maintenance in forestry and is especially suitable for scenarios that require continuous maintenance, such as economic forests and nurseries.

[0013] 2. This utility model adopts a design of four fixing blocks, bolts and fastening nuts. The tightness of the ring blocks can be adjusted by tightening the nuts, so that the two ring blocks tightly wrap around the tree trunk. This avoids both the problem of being too loose and causing air leakage and rain or snow to enter, and the problem of being too tight and damaging the tree trunk. It can adapt to the fitting needs of different tree trunk thicknesses. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-5 A forestry tree antifreeze device includes two annular blocks 1. The annular blocks 1 serve as the basic load-bearing frame of the entire device, integrating and installing an antifreeze sleeve 100, a fixing connection component 2, and a connecting block 4. This ensures the orderly assembly and coordinated operation of all functional components. Simultaneously, through its rigid structure, it maintains the device's wrapping shape around the tree trunk, preventing deformation due to external forces. The annular blocks 1 are made of high-strength PP plastic. The antifreeze sleeve 100 is installed on the inner wall of the annular blocks 1, directly adhering to the tree trunk surface. It is the core component of physical antifreeze, blocking external low-temperature intrusion through its own insulation layer, preventing frost damage to the tree bark, and isolating rain and snow from direct contact with the tree trunk to prevent ice formation. The antifreeze sleeve 100 uses composite insulation material. Made of high-quality materials, the inner layer is flame-retardant fiberglass insulation cotton, and the outer layer is PVC waterproof cloth. The insulation cotton is tightly bonded to prevent rain and snow from seeping into the insulation layer and causing moisture damage and failure. It is also scratch-resistant and suitable for outdoor woodland environments. A connecting block 4 is installed on the ring block 1, and a support frame 5 is installed at the bottom of the connecting block 4. The support frame 5 serves as the ground support structure of the device. It supports the weight of the ring block 1 through the connecting block 4, and supports the device stably on the ground, preventing the device from directly pressing on the base of the tree trunk, while also improving wind resistance. An insertion rod 6 is set on the support frame 5. The bottom end of the insertion rod 6 penetrates the support frame 5 and extends to its outside. The insertion rod 6 is inserted into the soil to form a ground anchor, preventing the support frame 5 from shifting when exposed to wind, snow or human touch, and further enhancing the overall stability of the device.

[0022] Two annular blocks 1 are connected by a fixed connection assembly 2. The fixed connection assembly 2 includes four fixed blocks 21, which are respectively installed on the front and back of the two annular blocks 1. The fixed blocks 21 and the annular blocks 1 are integrally formed. A bolt 22 is provided on the fixed block 21 on the left side. The right end of the bolt 22 passes through the two fixed blocks 21 from left to right and extends to their exterior. A fastening nut 23 is threaded on the surface of the bolt 22 and on the fixed block 21 on the right side. The fastening nut 23 locks the position of the fixed block 21 by friction, maintaining the contact pressure of the annular block 1 on the tree trunk. The bolt 22 passes through the two symmetrical fixed blocks 21 and cooperates with the fastening nut 23 to realize the tightness adjustment of the annular blocks 1. When the nut is turned clockwise, the two annular blocks 1 are tightened, enhancing the fit between the antifreeze sleeve 100 and the tree trunk. When the nut is turned counterclockwise, the annular blocks 1 can be loosened for disassembly or size adjustment.

[0023] The annular block 1 and the antifreeze sleeve 100 are connected by a limiting and disassembly assembly 3. The limiting and disassembly assembly 3 includes slots 31 and pull blocks 32. There are two slots 31, which are respectively opened at the bottom of the two antifreeze sleeves 100 on the opposite side. The slots 31 serve as insertion channels for the insert blocks 33, achieving initial positioning of the antifreeze sleeve 100 and the annular block 1, and preventing the antifreeze sleeve 100 from shifting during installation. There are two pull blocks 32, which are respectively set in the grooves of the two annular blocks 1 on the opposite side. The surface of the pull block 32 is in contact with the inner wall of the groove. The pull block 32 is equipped with a pull ring, which facilitates the operation of the pull block 32. Pulling block 32 drives locking block 34 to move. When pulled, locking block 34 disengages from slot 35, separating the antifreeze sleeve 100 from the annular block 1. An insert block 33 is installed on the inner wall of the annular block 1, corresponding to the slot 31. The side of insert block 33 near slot 31 penetrates the slot 31 and extends into it, contacting the inner wall of the slot 31. Inserting insert block 33 into slot 31 forms a preliminary mechanical connection between the antifreeze sleeve 100 and the annular block 1, preventing the antifreeze sleeve 100 from falling off longitudinally. Insert block 33 and annular block 1 are integrally formed. Pulling block 32 has locking block 34 installed on the side near slot 31. A slot 35 is provided on the inner wall corresponding to the position of the locking block 34. The side of the locking block 34 near the slot 35 passes through the annular block 1, the insert block 33, the slot 31, and the slot 35 in sequence, and extends into the interior of the slot 35 to contact the inner wall of the slot 35. The locking block 34 can be inserted into the slot 35 as the pull block 32 moves, forming a secondary lock between the antifreeze sleeve 100 and the annular block 1, further enhancing the connection stability. Two iron blocks 36 are installed on the side of the pull block 32 near the slot 31. After the iron blocks 36 are inserted into the positioning groove 37, they are attracted by the magnet 38 to fix the position of the pull block 32 and prevent the locking block 34 from accidentally dislodging from the slot 35. The iron blocks 36 are made of permanent metal. Made of magnetic ferrite, a positioning groove 37 is provided in the groove of the annular block 1 corresponding to the position of the iron block 36. The side of the iron block 36 near the positioning groove 37 passes through the positioning groove 37 and extends into it, contacting the inner wall of the positioning groove 37. The positioning groove 37 guides and ensures that the iron block 36 and the magnet 38 are accurately aligned, avoiding magnetic displacement that would cause the pull block 32 to loosen. A magnet 38 is installed on the inner wall of the positioning groove 37, which attracts the iron block 36. The magnet 38 fixes the pull block 32 by the attraction force with the iron block 36, and helps to maintain the locked state of the locking block 34 and the locking groove 35. The magnet 38 is made of neodymium iron boron strong magnet with an attraction force of 8N.

[0024] When the antifreeze sleeve 100 needs to be removed, first pull the pull block 32 outward to make the locking block 34 disengage from the locking slot 35, and at the same time drive the iron block 36 to disengage from the magnet 38. Then pull the antifreeze sleeve 100 upward, and the antifreeze sleeve 100 will drive the slot 31 to move upward and separate from the insertion block 33, thus completing the separation of the antifreeze sleeve 100 from the ring block 1.

[0025] Select the appropriate anti-freezing sleeve 100 with the corresponding inner diameter based on the tree's diameter at breast height (DBH): if the tree's DBH is 5-10cm, select an anti-freezing sleeve 100 with an inner diameter of 12-15cm; if the DBH is 10-15cm, select an anti-freezing sleeve 100 with an inner diameter of 18-22cm; if the DBH is 15-20cm, select an anti-freezing sleeve 100 with an inner diameter of 25-28cm. Ensure that the anti-freezing sleeve 100 fits snugly against the tree trunk without excessive gaps that could cause air leakage.

[0026] In use, attach the two annular blocks 1 of the assembled antifreeze sleeve 100 to both sides of the tree trunk, so that the antifreeze sleeve 100 completely covers the lower middle part of the tree trunk. Adjust the position of the annular blocks 1 to ensure that the four fixing blocks 21 on the front and back of the two annular blocks 1 are completely aligned. At the same time, confirm that the antifreeze sleeve 100 is wrinkle-free and fits the tree trunk surface. Insert the bolt 22 into the reserved hole of the left fixing block 21, and pass through the two aligned fixing blocks 21 in sequence on the right until the end of the bolt extends out of the right fixing block 21. Tighten the fastening nut 23 by hand until it fits the right fixing block 21. Then, use a regular wrench to turn the nut clockwise. Adjust the bolt 22, insert it into the reserved hole of the left fixing block 21, and pass through the two aligned fixing blocks 21 in sequence on the right until the end of the bolt extends out of the right fixing block 21 by about 2-3 cm. Tighten the fastening nut 23 by hand until it initially fits the right fixing block 21. Then, use a regular wrench to turn the nut clockwise. At the same time, ensure that the support frame 5 is in contact with the ground. Insert the insertion rod 6 through the support frame 5 into the soil to complete the installation.
