[0002] In the process of tree grafting, branch wrapping is an important part. The traditional method often uses manual wrapping, which is not only inefficient, but also difficult to ensure the wrapping effect, affecting the grafting survival rate. Therefore, an efficient and automatic tree grafting branch wrapping device and method are needed to solve this problem.

[0003] A Chinese patent with the authorization announcement number CN220422526U discloses an easily disassembled tree grafting device, which includes a first support block, a second support block is arranged on one side of the first support block, an adjustment mechanism is arranged on one side of the first support block and the second support block, and a disassembly mechanism is arranged inside the first support block and the second support block. The easily disassembled tree grafting device respectively sleeves the upper and lower first support blocks and the second support blocks on both sides of the grafting port, and according to the actual situation of the tree branches, presses the pressing block inward into the installation box, compresses the spring, and under the elastic force of the spring, the pressing block is ejected from the through hole, and the adjustment rod is fixed, which can be used to adjust the specific positions of the upper and lower first support blocks and the second support blocks. By arranging the first support blocks and the second support blocks at different positions on both sides of the grafting port of the tree branches, stable support for the tree branches can be achieved, avoiding the problem of failure to support, thereby affecting the grafting effect.

[0004] However, when the above device is used, it cannot adapt to and fix trees of different diameters, and can only fix trees of fixed diameters, and its adaptability is poor; and when grafting tree branches, their humidity, air permeability and isolation must be guaranteed to improve the survival rate of the grafted trees. Summary of the invention

[0005] In order to solve the technical problems in the background technology that the fixing device has poor adaptability and cannot perform good protection and isolation, the present invention provides a device and method for wrapping grafted branches of forest trees.

[0006] The present invention is implemented by the following technical scheme: a forest grafted branch wrapping device, including a device shell, a kinetic energy mechanism, and a re-cutting mechanism: A handle is fixedly connected to one side of the device housing, a control button is arranged on one side of the handle, and the control button is electrically connected to the inside of the device housing; The kinetic energy mechanism is arranged in the device housing, and the kinetic energy mechanism comprises a driving member, a wrapping member and a cutting member; The re-cutting mechanism is arranged at the top of the device shell, and includes a reset member and a cutting member. The reset member is used to reset the package after it is wound to the top, and the cutting member is synchronously started to cut the package when the package is reset.

[0007] Through the above technical scheme, the grafted trees can be quickly wrapped by utilizing the cooperation of the kinetic mechanism and the re-cutting mechanism, thereby effectively improving the efficiency of tree grafting, and with the cooperation of the parts of the wrapping piece, it can be well adapted to trees of different diameters, and the grafting tape can be abutted during wrapping, further simplifying the workers' operation and improving the wrapping efficiency; and after the wrapping is completed, it can automatically return to its position under the re-cutting mechanism, and can use inertia to cut the grafting tape, which is convenient for the next tree wrapping. Since the wrapping piece can fit the diameter of the tree, and then with the use of the grafting tape, its thickness can be reduced and it can also fit well on the outer wall of the tree, which greatly improves the practicability of the equipment.

[0008] As a further improvement of the above scheme, the driving member includes a guide groove opened on the inner wall of the device shell, the guide groove is spiral and ascending, the starting position of the guide groove is located directly below the end position, a guide plate is slidably connected in the guide groove, a turntable is fixedly connected to the inner side of the guide plate, a sleeve shaft 2 is fixedly connected to the top of the turntable, a sleeve shaft 1 is vertically slidably connected to the inner wall of the sleeve shaft 2, a rotating shaft is vertically slidably connected in the sleeve shaft 1, a motor is fixedly connected to the top of the rotating shaft, a protective cover is installed on the outside of the motor, and the protective cover is fixedly connected to the top of the device shell, and a heat dissipation hole is opened on the outer wall of the protective cover.
