[0002] Forestry planting refers to a series of activities that involve planting, nurturing, protecting and utilizing trees through artificial means. These activities cover multiple links from the initial tree species selection, forest land preparation, planting process, to subsequent tree care, pest and disease control, and ultimately timber harvesting and forest renewal. Forestry planting is of great significance in maintaining ecological balance, protecting the natural environment, and promoting economic development.

[0003] When winter comes, workers usually carry out cold protection for trees. In the prior art, the most commonly used anti-freeze protection is usually to wrap thermal insulation materials around the trunks of trees. Commonly used thermal insulation materials include thermal insulation tapes, straw ropes and non-woven fabrics. These thermal insulation materials need to be wrapped in circles during the installation process, which is cumbersome and inconvenient. It takes a long time to wrap and install a tree, and it is inconvenient to remove the thermal insulation materials when anti-freeze is not needed. Utility Model Content

Each fixing belt is fixed with a plurality of positioning rods evenly distributed along its length direction. Corresponding to each fixing belt, a plurality of positioning holes evenly distributed along the circumferential direction and communicating with each other inside and outside are opened on the protection belt. The positioning rods on each fixing belt are independently inserted into the positioning holes aligned with the fixing belt, and the positioning rods and the positioning holes are interference fit.

[0006] Furthermore, a plurality of card blocks are horizontally fixed on the inner wall of the protective belt and are evenly spaced along its length direction. Corresponding to the card blocks, a plurality of card slots for mounting the card blocks are opened on the insulation layer. Limit blocks are fixed on the upper and lower side walls of each card block, and limit slots for engaging the limit blocks are fixed on the upper and lower groove walls of each installation groove.

[0007] Furthermore, the cross-sections of all the limiting blocks and limiting grooves are semicircular structures.

[0008] Furthermore, the protective belt is made of elastic material.

[0009] Furthermore, the thermal insulation layer is made of thermal insulation material.

[0010] Furthermore, a plurality of grooves are provided on the upper and lower side walls and the upper and lower ends of the inner wall of the thermal insulation layer.

[0011] Furthermore, all the fixing straps are made of elastic material.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. Fix the insulation layer detachably on the inner surface of the protective belt, wrap the protective belt around the tree trunk, pull the fixing belt, align the positioning rod on the fixing belt with the positioning hole on the protective belt, insert the positioning rod into the positioning hole, and make the fixing belt unable to be easily loosened through the interference fit between the positioning rod and the positioning hole. Install each fixing belt on the protective belt one by one through the above method, so as to fix the protective belt wrapped around the tree trunk and prevent it from loosening and falling.

[0023] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0024] Example 1

[0025] A tree protection device described in this embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, it includes a protective belt 1, which is wrapped around the tree trunk in a tubular shape. The protective belt 1 is made of natural rubber, synthetic rubber, silicone rubber, polyurethane, ethylene-propylene rubber, vinyl chloride rubber and butyl rubber. The trunk of each tree has a different shape and style. When the protective belt 1 is wrapped around the tree trunk, the protective belt 1 can be tightened with a little force, so that the protective belt 1 can be deformed according to the shape of the tree trunk through the elasticity of the protective belt 1 itself, so that the thermal insulation layer 2 can fit the surface of the tree trunk better, reduce the gap between the surface of the tree trunk and the thermal insulation layer 2, and achieve a better thermal insulation effect;

[0026] The inner wall of the protective belt 1 is detachably fixed with an insulation layer 2. In the present embodiment, a plurality of blocks 7 are horizontally fixed on the inner wall of the protective belt 1 and are evenly spaced along its length direction. A plurality of slots for mounting the blocks 7 are provided on the insulation layer 2 corresponding to the blocks 7. Limiting blocks 8 are fixed on the upper and lower side walls of each block 7. Limiting slots for engaging the limiting blocks 8 are fixed on the upper and lower groove walls of each installation groove. The lengths of the blocks 7 and the limiting blocks 8 are the same as the length of the protective belt 1. The two ends of the blocks 7 and the limiting blocks 8 are flush with the two ends of the protective belt 1. The cross-sections of the limiting blocks 8 and the limiting grooves are semicircular structures. The limiting blocks 8 are supported by materials such as natural rubber, synthetic rubber or silicone. When in use, the insulation layer 2 is spread on the inner surface of the protective belt 1, and the blocks 7 and the limiting blocks 8 are installed in the slots. In the process of entering the slots, the limiting blocks 8 are squeezed by the groove walls and deformed, and the limiting blocks 8 move to After being placed in the limiting groove, it will quickly restore its original shape and engage in the corresponding limiting groove, blocking the block 7 from moving out of the slot and preventing the block 7 from easily falling out of the slot. During disassembly, the staff only needs to pull the thermal insulation layer 2 to easily disassemble the thermal insulation layer 2, and the thermal insulation layer 2 can be replaced conveniently and quickly. When the protective belt 1 needs to be used again in the future, it only needs to be surface cleaned and disinfected before it can be used again; of course, the detachable fixing method between the protective belt 1 and the thermal insulation layer 2 can also adopt bolts and nuts, and the protective belt 1 and the thermal insulation layer 2 are provided with a plurality of through holes that are the same as the through holes of the bolts, and corresponding to all the through holes, the inner wall of the thermal insulation layer 2 is provided with avoidance grooves for the hexagonal heads of the bolts, and after the bolts pass through the through holes on the protective belt 1 and the thermal insulation layer 2, the hexagonal heads are engaged in the avoidance grooves, and the nuts are sleeved on the threaded ends of the bolts, so that the thermal insulation layer 2 can be detachably fixed to the inner wall of the protective belt 1;

[0027] The insulation layer 2 is made of materials such as polyurethane sponge, memory foam, rubber and plastic sponge, and open-pore sponge. These materials have good insulation effect and certain elasticity, so that they can better fit the surface of the tree trunk and achieve better insulation effect.

[0028] A plurality of grooves 3 are provided on the upper and lower side walls and the upper and lower ends of the inner wall of the thermal insulation layer 2. The grooves 3 are provided on the upper and lower side walls and the upper and lower ends of the inner wall of the thermal insulation layer 2. The grooves 3 can utilize the habits of certain insects to allow the unearthed larvae of the pests to pupate or the pests to lay eggs inside them, and the eggs of these pests can be concentratedly eliminated, thereby reducing the harm of the pests to the trees;

[0029] A plurality of fixing belts 4 are fixed on one end of the protective belt 1. The fixing belts 4 are made of natural rubber, synthetic rubber, silicone rubber, polyurethane, ethylene-propylene rubber, vinyl chloride rubber, butyl rubber and other materials. When the protective belt 1 is deformed, the position of the positioning hole 5 thereon will certainly be offset. The fixing belt 4 can stretch its length slightly through its own elasticity, so as to adapt to the different position offsets of the positioning hole 5.

[0030] Each fixing belt 4 is fixed with a plurality of positioning rods 6 evenly distributed along its length direction, the cross section of the positioning rods 6 is circular, and all the positioning rods 6 are horizontally fixed to the side wall of the fixing belt 4 attached to the outer surface of the protective belt 1;

[0031] Corresponding to each fixing belt 4, a plurality of positioning holes 5 are evenly distributed along the circumferential direction and communicated with each other inside and outside on the protection belt 1. The positioning holes 5 are circular in shape. When in use, the positioning holes 5 can play a ventilation effect, allowing the air inside and outside the protection belt 1 to circulate, so that the pores on the bark can exchange gas normally, thereby avoiding the phenomenon of suffocation of the wrapped part of the trunk;

[0032] The positioning rods 6 on each fixing belt 4 are independently inserted into the positioning holes 5 aligned therewith, and there is an interference fit between the positioning rods 6 and the positioning holes 5. In use, after the protection belt 1 is wrapped around the tree trunk, the fixing belt 4 is pulled, the positioning rods 6 on the fixing belt 4 are aligned with the positioning holes 5 on the protection belt 1, and the positioning rods 6 are inserted into the positioning holes 5. The interference fit between the positioning rods 6 and the positioning holes 5 makes it impossible for the fixing belt 4 to be easily loosened. Each fixing belt 4 is installed on the protection belt 1 one by one through the above method, so as to fix the protection belt 1 wrapped around the tree trunk and prevent the protection belt 1 from loosening and falling. When disassembling, it is only necessary to pull the fixing belt 4 and pull the positioning rods 6 out of the positioning holes 5. The disassembly and assembly method is simple and quick, which can improve the disassembly and assembly efficiency of the staff.

[0033] In actual use, first, the heat preservation layer 2 is spread on the inner surface of the protection belt 1, and the card block 7 and the limit block 8 are inserted into the card slot. In the process of entering the card slot, the limit block 8 is squeezed by the slot wall and deformed. After the limit block 8 moves to the limit slot, it will quickly restore its original shape and engage in the corresponding limit slot, blocking the card block 7 from moving out of the card slot, preventing the card block 7 from easily falling out of the card slot, and the heat preservation layer 2 can be disassembled and assembled conveniently and quickly. When the protection belt 1 is wrapped around the tree trunk, the protection belt 1 is tightened with a little force. The elasticity of the protection belt 1 itself allows the protection belt 1 to be deformed according to the shape of the tree trunk, so that the heat preservation layer 2 can be easily disassembled and assembled. Layer 2 can fit the surface of the tree trunk more closely and achieve better heat preservation effect. Then, pull the fixing belt 4, align the positioning rod 6 on the fixing belt 4 with the positioning hole 5 on the protective belt 1, and insert the positioning rod 6 into the positioning hole 5. The interference fit between the positioning rod 6 and the positioning hole 5 makes it impossible for the fixing belt 4 to be easily loosened. Each fixing belt 4 is installed on the protective belt 1 one by one through the above method, so as to fix the protective belt 1 wrapped around the tree trunk and prevent the protective belt 1 from loosening and falling. When disassembling, it is only necessary to pull the fixing belt 4 and pull the positioning rod 6 out of the positioning hole 5. The disassembly and assembly method is simple and quick, which can improve the disassembly and assembly efficiency of the staff.
