Description

Technical Field

[0001] The utility model belongs to the technical field of tree tumor removal, and in particular relates to a tree tumor removal device. Background Art

[0002] Tree tumors are callus tissues, which are a form of self-protection formed by asexual cell reproduction after a tree is injured. There are many causes of tree tumors, which can generally be divided into external damage type and bacterial infection type. As the name suggests, the external damage type is that after the tree is physically damaged, the sieve tube breaks and causes local overnutrition, which triggers disordered cell division to form tumor-like tissue. The external damage type sometimes also includes damage caused by pests and diseases, such as the borer of longhorn beetles. As for the bacterial infection type, due to the diversity of bacterial species, we generally refer to it as tumor bacterial infection.

[0003] Tree nodules will occupy some of the nutrients and energy, thus limiting the growth of the tree. In addition, they may make the tree more vulnerable to other diseases and pests, destroying the normal structure and defense mechanism of the tree. Therefore, tools are needed to remove them to avoid long-term damage to the overall health of the tree. However, saws and pruning knives are currently used to remove tree nodules, and there are no tools specifically for removing tree nodules. Therefore, we proposed a tree nodule removal device to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a tree tumor removal device which is specially used for removing tree tumors so as to improve the efficiency of tree tumor removal work.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] The tree knot removal device comprises a first rotating disk and a second rotating disk, wherein the first rotating disk and the second rotating disk are rotationally connected via a rotating shaft, and a first handle and a second handle are respectively fixedly mounted on the first rotating disk and the second rotating disk, and a locking ring which can be fixed at any position on the first rod is sleeved on the first rod, and an arc-shaped cutter head is fixedly mounted on the locking ring.

[0007] It is further defined that the locking ring is C-shaped, a fixing block is fixedly mounted on the locking ring, a locking bolt is threadedly connected to the fixing block, a force-bearing rod is movably inserted on the locking bolt, and both ends of the force-bearing rod are provided with limiting balls. With such a structural design, it is more labor-saving to rotate the locking bolt through the force-bearing rod, and it is convenient to adjust the position of the locking ring on the first handle.

[0008] It is further defined that a strip groove is formed on the first handle, a limiting convex strip is fixedly installed on the inner wall of the locking ring, and the limiting convex strip is slidably installed in the strip groove. With such a structural design, the limiting convex strip extends into the strip groove, and the strip groove cooperates with the limiting convex strip to limit the locking ring, thereby preventing the arc-shaped cutter head from axially rotating on the first handle, which would affect the use.

[0009] It is further defined that the first handle and the second handle are both fixedly mounted with threaded sleeves, the first handle and the second handle are both threadedly connected with extension rods, and the ends of the extension rods are provided with rubber sleeves. With such a structural design, the power arm can be lengthened by the extension rod, which is more labor-saving when used, and after disassembly, the removal device can occupy less space, making it easier to store and carry.

[0010] It is further defined that a fixing seat is fixedly mounted on the second handle, and a positioning tie is fixedly mounted on the fixing seat. With such a structural design, the second handle can be tied to the tree trunk through the positioning tie, and when the arc-shaped blade is used to remove the tree tumor, the tree tumor removal device can be prevented from sliding during use, making it more convenient to use.

[0011] It is further defined that the first and second rotating disks are both provided with a pruning head, the pruning head is provided with a plug-in strip, the first and second rotating disks are provided with a slot that matches the plug-in strip, the first and second rotating disks are provided with a threaded groove that is connected to the slot, the threaded groove is threadedly connected with a clamping bolt, and the plug-in strip is provided with a groove that matches the end of the clamping bolt. With such a structural design, the clamping bolt and the plug-in strip can fix the pruning head on the first and second rotating disks, making it convenient to replace the pruning head when it is damaged.

[0012] The utility model adopting the above technical solution has the following advantages:

[0013] The utility model uses the first rod, the second rod and the first rotating disk and the second rotating disk to enclose the tree trunk, and then adjusts the position of the locking ring on the first rod so that when the first rod and the second rod are closed together, the arc-shaped blade head can fit the tree trunk to shovel the tree knot. When removing the tree knot, there is no need to adjust the pruning direction, and larger tree knots on the tree trunk can be removed. It is more convenient to use and the efficiency of removing the tree knot is improved. BRIEF DESCRIPTION OF THE DRAWINGS
