Description

A device for girdling bark of the monsoon tree without petals Technical Field

[0001] This utility model relates to the field of forestry management tools, and in particular to a device for girdling the bark of the monsoon tree. Background Technology

[0002] *Avicennia marina*, a large tree species belonging to the Avicenniaceae family, is naturally distributed in low-salinity mudflats. It exhibits strong resilience and rapid growth, making it a fast-growing species suitable for afforestation in the low-tide zone. However, as an introduced species, its rapid growth in some areas has led to the shading of other native plant species, hindering their survival and reducing biodiversity. The root cause is its excessively rapid reproduction and growth. To address this issue, management personnel need to control its population by girdling and injecting chemicals to kill some of the bark, thus preventing the extinction of other species in the region. Currently, girdling is done manually, which is slow and prone to hand injuries. Therefore, we propose a girdling device for *Avicennia marina* bark. Summary of the Invention

[0003] The main purpose of this invention is to provide a device for girdling bark of the monsoon tree without petals, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A device for girdling bark of the monsoon tree (Avicennia marina) includes a right clamping ring and a left clamping ring. One end of the right and left clamping rings is movably connected by a hinge. A clamping handle is fixedly installed on the outer arc surface of both the right and left clamping rings near the other end. A telescopic groove is formed in the middle of the surface of both the right and left clamping rings. A telescopic sleeve is fixedly installed in the middle of the outer arc surface of both the right and left clamping rings. The telescopic sleeve communicates with the telescopic groove, and a cutting structure is fixedly installed inside the telescopic sleeve.

[0006] Preferably, a rubber sleeve is fixedly fitted onto the surface of the clamping handle, and the surface of the rubber sleeve is provided with anti-slip texture.

[0007] Preferably, the inner surfaces of the right clamping ring and the left clamping ring are both smooth surfaces.

[0008] Preferably, the cutting structure includes a miniature bearing, a lead screw, a knob, an inner threaded sleeve, and a cutting blade. The miniature bearing is fixedly installed on the inner surface of the telescopic sleeve near one end. The lead screw is fixedly installed in the middle of the miniature bearing. A knob is fixedly connected to one end of the lead screw, and an inner threaded sleeve is spirally fitted to the other end of the lead screw. A cutting blade is fixedly connected to one end of the inner threaded sleeve.

[0009] Preferably, the lead screw is movably mounted in the telescopic sleeve via a miniature bearing, the cutting blade is movably disposed in the telescopic groove, and the cutting edges of the cutting blades on the right and left clamping rings face opposite directions.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention relates to a device for girdling bark of the monsoon tree without petals. It can quickly girdle the bark of the monsoon tree without petals, and it is simple and convenient to operate without hurting the hands. The cutting depth can also be adjusted through the cutting structure to accommodate the thickness of the bark of trees with various growth rings. The structure is simple, portable, and more practical. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Example 1:

[0019] As shown in Figures 1-4, a device for girdling bark of the monsoon tree includes a right clamping ring 1 and a left clamping ring 2. One end of the right clamping ring 1 and the left clamping ring 2 are movably connected by a hinge 3. A clamping handle 4 is fixedly installed on the outer arc surface of the right clamping ring 1 and the left clamping ring 2 near the other end. A telescopic groove 5 is opened in the middle of the surface of the right clamping ring 1 and the left clamping ring 2. A telescopic sleeve 6 is fixedly installed in the middle of the outer arc surface of the right clamping ring 1 and the left clamping ring 2. The telescopic sleeve 6 is connected to the telescopic groove 5. A cutting structure 7 is fixedly installed inside the telescopic sleeve 6. When in use, the inner surface of the right clamping ring 1 and the right clamping ring 2 can be coated with lubricant or lubricating oil to reduce friction during rotation and make rotation easier.

[0020] A rubber sleeve is fixedly fitted onto the surface of the clamping handle 4, and the surface of the rubber sleeve has anti-slip texture; the inner surfaces of the right clamping ring 1 and the left clamping ring 2 are both smooth; the cutting structure 7 includes a miniature bearing 71, a lead screw 72, a knob 73, an inner threaded sleeve 74, and a cutting blade 75. The miniature bearing 71 is fixedly installed on the inner surface of the telescopic sleeve 6 near one end, the lead screw 72 is fixedly installed in the middle of the miniature bearing 71, one end of the lead screw 72 is fixedly connected to the knob 73, and the other end of the lead screw 72 is helically fitted with an inner threaded sleeve 74. One end of the inner threaded sleeve 74 is fixedly connected to a cutting blade 75. Turning the knob 73 causes the lead screw 72 to rotate, allowing the inner threaded sleeve 74 to extend and retract within the telescopic sleeve 6. This, in turn, drives the connected cutting blade 75 to extend and retract within the telescopic groove 5, thereby controlling the extension length of the cutting blade 75. This allows for the cutting of thicker bark. The lead screw 72 is movably mounted in the telescopic sleeve 6 via a miniature bearing 71. The cutting blade 75 is movably positioned within the telescopic groove 5. The cutting edges of the cutting blades 75 on the right clamping ring 1 and the left clamping ring 2 face opposite directions.

[0021] It should be noted that this utility model is a bark girdling device for the bark of the monsoon tree. In use, the operator can clamp the right clamping ring 1 and the right clamping ring 2 on the surface of the trunk to be cut, and then clamp the right clamping ring 1 and the right clamping ring 2 towards the middle by clamping the handle 4, so that the cutting blades 75 on both sides are inserted into the bark. Then, rotate the device clockwise around the trunk for one full turn, so that the blades of the cutting blades 75 can make a girdling on the trunk. After the girdling, inject the prepared agent into the cut, thereby completing the treatment of the tree.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
