Description

Technical Field

[0001] This utility model belongs to the field of forestry technology and relates to a cold-resistant device for forest trees. Background Technology

[0002] Forestry engineering refers to activities that apply various engineering technologies to forest resource cultivation, development, utilization, and forest product processing, based on the principles of efficient utilization and sustainable development of forest resources. Because low temperatures significantly impact tree growth, forestry cold-resistant measures are necessary to protect trees from damage caused by low temperatures, ensure healthy tree growth, and thereby improve the overall ecological and economic benefits of forests.

[0003] Patent CN207235641U discloses a frost protection device for forestry trees, including a foundation on which trees are planted. The outer wall of the tree is coated with a layer of lime, and the outer wall of the lime layer is covered with pearl cotton. The outer wall of the pearl cotton is wrapped with a plastic film layer, and the outer wall of the plastic film layer is wrapped with a straw mat. Four pipe clamps are bolted to the outer wall of the straw mat, and these four pipe clamps are evenly spaced on the outer wall of the straw mat. A connecting block is fixedly connected to one side of each pipe clamp, and a diagonal brace is connected to the bottom of the connecting block by screws. This patent, by applying a layer of lime to the lower part of the tree, primarily prevents frost damage to the tree, facilitating its safe overwintering and protecting it from external natural damage. The pearl cotton enhances the insulation and cold resistance, while the plastic film layer and straw mat strengthen the tree's waterproof and cold-resistant capabilities, respectively.

[0004] However, the antifreeze device in the aforementioned patent is not convenient to adjust according to the thickness of the tree. Furthermore, when the vertical length of the tree to be wrapped is large, multiple tube clamps are prone to vertical displacement during long-term use, which makes it impossible to guarantee the stability of the wrapping material and reduces the antifreeze and cold resistance effect on the tree.

[0033] See appendix Figure 1-6 This utility model discloses a cold-resistant device for forest trees, including a heat-insulating unit 2 and three adjustable fastening units. The heat-insulating unit 2 covers the outer wall of the tree body 1. The three adjustable fastening units are evenly fitted on the outside of the heat-insulating unit 2 from top to bottom. The top of the middle adjustable fastening unit is connected to the upper adjustable fastening unit through a telescopic connecting component. The bottom of the middle adjustable fastening unit is connected to the lower adjustable fastening unit through a telescopic connecting component. A support structure is provided on the outside of the middle adjustable fastening unit. The end of the support structure away from the adjustable fastening unit is inserted into the foundation.

[0034] In this embodiment, the adjustable fastening unit can be adjusted according to the thickness of the tree 1 to increase the range of use. The three adjustable fastening units are connected by a telescopic connecting component to prevent the three adjustable fastening units from shifting vertically, which can ensure the stability of the fastening of the heat insulation unit 2 and improve the frost resistance and cold protection effect of the tree.

[0035] The adjustable fastening unit includes a first arc plate 31 and a second arc plate 32, which are rotatably connected by a rotating shaft 33.

[0036] The second arc plate 32 is fixedly provided with multiple fixing plates 51 at the end away from the rotating shaft 33. The first arc plate 31 is provided with multiple arc grooves 311 at the end away from the rotating shaft 33. A slider 56 is slidably connected inside the arc groove 311. One end of the slider 56 is connected to the inner wall of the arc groove 311 by a spring 55. The other end of the slider 56 is fixedly connected to a connecting plate 54. The connecting plate 54 is flexible.

[0037] The end of the connecting plate 54 away from the slider 56 extends outward from the arc groove 311, and a first female hook and loop fastener 53 is fixedly provided on the inner side of the extended end of the connecting plate 54, and a first male hook and loop fastener 52 is fixedly provided on the outer side of the fixing plate 51. The first female hook and loop fastener 53 and the first male hook and loop fastener 52 are bonded to each other.

[0038] In this embodiment, each adjustable fastening unit is provided with two arc-shaped grooves 311, two connecting plates 54, and two fixing plates 51. In use, the connecting plate 54 is pulled by hand, causing the slider 56 to slide in the arc-shaped groove 311, thereby increasing the exposed length of the connecting plate 54, thus enlarging the inner diameter between the first arc-shaped plate 31 and the second arc-shaped plate 32. Then, the first female Velcro 53 and the first female Velcro 52 are glued and fixed. When it is necessary to reduce the inner diameter between the first arc-shaped plate 31 and the second arc-shaped plate 32, the hand is released, and the slider 56 slides under the pull of the spring 55. The slider 56 causes the connecting plate 54 to retract into the arc-shaped groove 311, thereby shortening the exposed length of the connecting plate 54.

[0039] The fixed end of the telescopic connection assembly is fixedly installed on the top or bottom of the adjustable fastening unit located in the middle, and the telescopic end of the telescopic connection assembly is fixedly installed on the bottom of the adjustable fastening unit located above or the top of the adjustable fastening unit located below. The telescopic connection assembly includes two sets of symmetrically arranged telescopic connection units, one set on the first arc plate 31 and the other set on the second arc plate 32.

[0040] The telescopic connection unit includes a fixed rod 61, a movable rod 62, and a connecting shaft 72. The fixed rod 61 has a vertical groove 611 inside that is adapted to the movable rod 62. A rotating handle 71 is rotatably mounted on the outer wall of the fixed rod 61. One end of the connecting shaft 72 is fixedly connected to the rotating handle 71, and the other end of the connecting shaft 72 passes through the outer wall of the fixed rod 61, extends into the vertical groove 611, and is fixedly connected to a drive gear 73. One end of the movable rod 62 located in the vertical groove 611 is fixedly provided with a rack 621, and the drive gear 73 is meshed with the rack 621.

[0041] In this embodiment, the drive gear 73 can be rotated by driving the handle 71, thereby achieving the vertical displacement of the moving rod 62 under the action of the drive gear 73 meshing with the rack 621. When the vertical length of the insulation unit 2 is large, the distance between the three adjustable fastening units can be adjusted by adjusting the extension length of the moving rod 62. Since the adjustable fastening unit in the middle is provided with a support structure on its outer side, when the telescopic connecting unit is connected, it can be ensured that the other two adjustable fastening units connected to the middle adjustable fastening unit will not move vertically, which can ensure the stability of the fastening of the insulation unit 2 and improve the frost resistance and cold protection effect of the tree; and the fixed rod 61 and the moving rod can also play an auxiliary role in fastening the insulation unit 2.

[0042] A locking unit 711 is provided on the rotating handle 71.

[0043] In this embodiment, the locking unit 711 can be a locking bolt, used to fix the extension length of the moving rod 62.

[0044] The support structure includes two sets of symmetrically arranged support units, one set on the first arc plate 31 and the other set on the second arc plate 32;

[0045] The support unit includes an upper connecting seat 41, a diagonal brace 42, a lower connecting seat 43, and a fixed cone 44. The upper connecting seat 41 is fixedly disposed on the outside of the first arc plate 31 or the second arc plate 32. One end of the diagonal brace 42 is hinged to the upper connecting seat 41, and the other end of the diagonal brace 42 is hinged to the lower connecting seat 43. The bottom of the lower connecting seat 43 is fixedly provided with a fixed cone 44.

[0046] In this embodiment, both ends of the diagonal brace 42 are hinged to the upper connecting seat 41 and the lower connecting seat 43, which can adapt to different terrains and facilitate the fixed installation of the fixed cone 44.

[0047] A second sub-hook and loop fastener 81 is fixedly connected to the inner side of one end of the insulation unit 2, and a second female hook and loop fastener 82 is fixedly connected to the outer side of the other end of the insulation unit 2. The second sub-hook and loop fastener 81 and the second female hook and loop fastener 82 are bonded to each other.

[0048] The insulation unit 2 includes a rubber base layer 21, with pearl cotton 22 fixedly connected to the inner side of the rubber base layer 21, and sponge 23 fixedly connected to the inner side of the pearl cotton 22; a fireproof metal wire mesh 24 is fixedly connected to the outer side of the rubber base layer 21, and a straw mat 25 is fixedly connected to the outer side of the fireproof metal wire mesh 24.

[0049] In this embodiment, the rubber base layer 21 achieves a waterproof effect, thus protecting the tree bark from cold water erosion during the cold winter season. The pearl cotton 22 and sponge 23 absorb most of the moisture from the tree bark, further preventing water erosion and protecting the tree. The straw mat 25 provides insulation, but it is flammable in the dry winter. To prevent the burning straw mat 25 from damaging the tree, a fireproof metal wire mesh 24 is installed, which provides a certain degree of fire prevention, reducing the possibility of fire spreading to the tree bark and protecting the tree to a greater extent.

[0050] Working principle: When in use, the insulation unit 2 is wrapped around the outside of the tree body 1 and fixed by the second sub-hook and hook and loop fastener 81 and the second female hook and loop fastener 82. Then, an adjustable fastening unit is placed in the middle of the insulation unit 2. The inner diameter between the first arc plate 31 and the second arc plate 32 in the adjustable fastening unit is adjusted according to the thickness of the tree body 1. The first female hook and loop fastener 53 is then fixed to the first sub-hook and loop fastener 52. The angle of the diagonal brace 42 is adjusted according to the terrain, and the fixing cone 44 is inserted into the foundation.

[0051] Based on the vertical length of the insulation unit 2, adjust the extension length of the top and bottom moving rods 62 of the adjustable fastening unit and fix them by the locking unit 711; finally, adjust the other two adjustable fastening units according to the thickness of the tree body 1, so that the other two adjustable fastening units are tightly fitted onto the insulation unit 2.

[0052] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
