Description

Technical Field

[0001] This application relates to the field of fruit tree cultivation technology, and in particular to a cutting device for fruit tree grafting. Background Technology

[0002] Fruit tree grafting is a common tree propagation technique that typically involves joining two different parts of a plant to achieve plant variety conversion or enhance plant growth. In the process of fruit tree grafting, the cutting equipment plays a crucial role, helping fruit farmers to make more precise cuts and improve the success rate and efficiency of grafting.

[0003] Grafting methods mainly include branch grafting and bud grafting. In branch grafting, a suitable part with healing ability is selected for cutting, and then the scion is inserted into the cut of the rootstock, fixed and protected, eventually forming a new active plant. Currently, fruit tree grafting mainly relies on traditional manual cutting, which requires manual strength from the operator. This is not only labor-intensive but also carries the risk of finger injury. Therefore, a cutting device for fruit tree grafting is proposed. Utility Model Content

[0004] To address the problem of the danger and slowness of manually cutting branches during fruit tree grafting, this application provides a cutting device for fruit tree grafting.

[0005] The cutting device for fruit tree grafting provided in this application adopts the following technical solution:

[0006] A grafting device for fruit trees includes a base, a support connected to the top of the base, a tool holder rotatably connected to the bottom of the support, a limit plate connected to one side of the support that is close to the other, a fixed gearbox connected to the top of the support, a fixed gear plate rotatably connected to the inner sides of the fixed gearbox, a handle connected to one side of the fixed gear plate, a connecting rod rotatably connected to the inner sides of the handle, a movable gearbox rotatably connected to the bottom of the connecting rod, a tension spring connected between the bottom of the fixed gearbox and the top of the movable gearbox, a push rod connected to the bottom of the movable gearbox, a push plate connected to the bottom of the push rod, a pressure rod connected to one side of the bottom of the push plate, a T-shaped plate slidably connected to the top of the push plate, a pressure plate connected to the bottom of the T-shaped plate, and a fixed spring connected to the bottom of the pressure plate.

[0007] Preferably, the tool holder includes a tool holder box, a pressure plate is slidably connected between the inner walls of the tool holder box, a return spring is connected to the bottom end of the pressure plate, and a tool is connected to the bottom end of the pressure plate.

[0008] Preferably, the pressure plate is provided with ear plates on both sides extending into the inside of the tool holder box, and a return spring is provided at the bottom end of the ear plate and the bottom end of the inner wall of the tool holder box.

[0009] Preferably, the bottom end of the limiting plate has a limiting hole corresponding to the top end of the tool holder, and the bottom end of the pressure rod passes through the limiting hole.

[0010] Preferably, the bottom end of the fixing spring is connected to the top end of the base.

[0011] Preferably, the tool holder box has through holes at the top corresponding to the pressure rod and at the bottom corresponding to the tool position.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. By rotating the handle, the fixed gear rotates, causing the connecting rod to drive the movable gearbox downward. The cooperation between the handle and the gear utilizes the handle to generate a large rotational force, which is then converted into a downward force and motion through the connecting rod. This better propels the blade to cut the branches, allowing the operator to control the entire cutting process through the handle. This method is energy-saving, labor-saving, simplifies the operation steps, and improves the ease of operation.

[0014] 2. A rotating blade holder is installed at the bottom of the support, allowing different blades to be used for different shearing needs. A spring connects the base and the pressure plate, which pulls the pressure plate upward when the push plate moves upward, facilitating the fixation of branches and enabling better shearing activities. This ensures the flatness of the shearing and the safety of the operator, and has the advantages of improving shearing effect, ease of operation, and safety. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses a cutting device for grafting fruit trees.

[0022] Reference Figure 1-3 A grafting device for fruit trees includes a base 1, a support 2 connected to the top of the base 1, a tool holder 3 rotatably connected to the bottom of the support 2, a limit plate 4 connected to one side of the support 2 that is close to each other, a fixed gearbox 5 connected to the top of the support 2, a fixed gear plate 6 rotatably connected between the inner sides of the fixed gearbox 5, a handle 7 connected to one side of the fixed gear plate 6, a connecting rod 8 rotatably connected between the inner sides of the handle 7, a movable gearbox 10 rotatably connected to the bottom of the connecting rod 8, a tension spring 9 connected between the bottom of the fixed gearbox 5 and the top of the movable gearbox 10, a push rod 11 connected to the bottom of the movable gearbox 10, a push plate 12 connected to the bottom of the push rod 11, a pressure rod 13 connected to one side of the bottom of the push plate 12, a T-shaped plate 14 slidably connected to the top of the push plate 12, a pressure plate 15 connected to the bottom of the T-shaped plate 14, and a fixed spring 16 connected to the bottom of the pressure plate 15.

[0023] Reference Figure 1 The tool holder 3 includes a tool holder box 31, and a pressure plate 32 is slidably connected between the inner walls of the tool holder box 31. A return spring 33 is connected to the bottom end of the pressure plate 32, and a tool 34 is connected to the bottom end of the pressure plate 32. The pressure plate 32 can distribute the pressure evenly on the tool when the pressure rod 13 falls, ensuring the flatness of the shearing.

[0024] Reference Figure 1 The pressure plate 32 has ear plates on both sides that extend into the tool holder box 31. The bottom end of the ear plate is connected to the bottom end of the inner wall of the tool holder box 31 with a return spring 33. After the tool 34 falls, the return spring 33 drives the pressure plate 32 to reset the tool 34, which is convenient for the next operation.

[0025] Reference Figure 1 The bottom end of the limiting plate 4 has a limiting hole corresponding to the top end of the tool holder 3. The bottom end of the pressure rod 13 passes through the limiting hole, ensuring that the push rod 11 drives the push plate 12 and the pressure rod 13 to run correctly and not deviate.

[0026] Reference Figure 1 The bottom end of the fixed spring 16 is connected to the top end of the base 1, so that the branches can be better fixed by the pressure plate 15.

[0027] Reference Figure 1 The top of the tool holder box 31 has through holes corresponding to the pressure rod 13 and the bottom has through holes corresponding to the tool 34. The top through hole facilitates the pressure rod 13 to make full contact with it when it falls, and the bottom through hole facilitates the tool 34 to extend and cut the branches.

[0028] The implementation principle of a cutting device for fruit tree grafting according to an embodiment of this application is as follows: When performing the cutting work, lift the handle 7 to make the fixed toothed disc 6 rotate, driving the connecting rod 8 and the movable gear box 10 to move upward. At the same time, the pressure plate 15 and the fixed spring 16 are pulled up by the T-shaped plate 14. Then, rotate the tool holder 3 to the required tool holder box 31, and press down the handle 7 to make the pressure plate 15 press and fix the branch. At the same time, after the fixed toothed disc 6 rotates, it drives the connecting rod 8 and the movable gear box 10 to move downward, driving the push plate 12 and the pressure rod 13 to press the pressure plate 32. Since the push plate 12 has a limit hole on one side, it will not affect the fixation of the branch by the pressure plate 15. The pressure rod 13 pushes the pressure plate 32 to use the tool 34 to cut the branch. After pressing to the bottom, release the handle 7. The tension spring 9 pulls the movable gear box 10 to return it to its original position for the next use. At the same time, it drives the pressure plate 15 to be released upward, and the branch is pulled out to cut the next one.
