Description

Technical Field

[0001] This utility model relates to the field of branch grafting technology, and in particular to a pretreatment device for grafted branches. Background Technology

[0002] Grafting is a plant asexual reproduction technique that combines branches of superior varieties with rootstocks possessing specific characteristics, allowing them to heal and grow synergistically. It can be divided into two main forms: branch grafting and bud grafting. Branch grafting uses only a single bud patch inserted into the rootstock bark, making the process more precise and saving scion material; it is mostly used for plants in their growing season. This technique preserves the superior traits of the parent plant while incorporating the rootstock's resistance to adverse conditions, and is widely used in the cultivation of fruit trees, flowers, and other economic crops.

[0003] Chinese Patent CN218125629U discloses a pretreatment device for grafted branches, including a U-shaped support and branches. The bottom of the U-shaped support's inner cavity has a first sliding groove and a second sliding groove. A grafting knife is installed at the bottom of the U-shaped support's inner cavity between the first and second sliding grooves. A first guide post is installed in the inner cavity of the first sliding groove, and a threaded rod is installed in the inner cavity of the second sliding groove. A knob is installed at one end of the threaded rod. An adjusting plate is threadedly connected to the surfaces of the first guide post and the threaded rod. The bottom of the adjusting plate has a first triangular groove. This device, through its series of structures, offers simple operation and solves the problem of pretreatment before grafting branches. Existing pretreatment devices typically use grafting knives and grafting shears, which are slow and require high technical skills. This device effectively controls the length of the branch cut, solving the problem that existing devices cannot adjust the cut length.

[0004] However, the above technical solution has the following shortcomings: when making a cut, the device not only needs to support the branch while pulling the connecting plate with the handle to press the pressure plate down on the branch, but also needs to overcome the tension of the spring during the pulling process before making the cut on the branch. In practice, this is very inconvenient and reduces the ease of use of the device. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a grafting branch pretreatment device that can not only quickly select the length of the branch cut, but also reduce the operational difficulty of making the branch cut and optimize the convenience of using the device.

[0006] The technical solution of this utility model is a pretreatment device for grafted branches, including a base and a fixing mechanism. A workbench is provided on the base, and a rotating shaft is rotatably connected inside the workbench. Two symmetrically distributed threaded blocks are threadedly connected to the rotating shaft. A first connecting frame is provided on the threaded blocks, and a movable block is provided on the first connecting frame.

A groove is provided inside the movable block for the guide sliders to slide horizontally. One end of the stabilizing rod passes through the movable block and is slidably connected. The spring is sleeved on the movable block.

[0007] Preferably, the shaft has two symmetrically distributed threaded portions with opposite thread directions, and the two threaded portions are respectively threadedly connected to the threaded blocks on both sides.

[0008] Preferably, the movable block is provided with two second connecting frames, and the second connecting frames are provided with guide blocks, which are slidably disposed inside the worktable.

[0009] Preferably, one end of the rotating shaft passes through the worktable and is provided with a handle.

[0021] Example 1

[0022] like Figures 1-4 As shown, the grafting branch pretreatment device proposed in this embodiment includes a base 1 and a fixing mechanism; a workbench 2 is provided on the base 1, and a rotating shaft 3 is rotatably connected inside the workbench 2. Two symmetrically distributed threaded blocks 4 are threadedly connected to the rotating shaft 3. The rotating shaft 3 has two symmetrically distributed threaded parts with opposite thread directions. The two threaded parts are respectively threadedly connected to the threaded blocks 4 on both sides. A first connecting frame 5 is provided on the threaded block 4. A moving block 6 is provided on the first connecting frame 5. One end of the rotating shaft 3 passes through the workbench 2 and is provided with a handle 13. Two second connecting frames 14 are provided on the moving block 6. A guide block 15 is provided on the second connecting frame 14. The guide block 15 is slidably disposed inside the workbench 2.

[0023] like Figure 1 and Figure 3 As shown, the fixing mechanism includes multiple symmetrically distributed connecting columns 8 slidably connected to the moving block 6, springs 7 disposed inside the moving block 6 with their two ends respectively disposed on the connecting columns 8 and the moving block 6, clamping plates 9 disposed on the connecting columns 8, four guide sliders 11 distributed in a ring array on the connecting columns 8, and stabilizing rods 12 coaxially disposed on the connecting columns 8; the moving block 6 has a groove inside for the guide sliders 11 to slide horizontally, one end of the stabilizing rod 12 passes through the moving block 6 and is slidably connected, the springs 7 are sleeved on the moving block 6, and the clamping plates 9 are provided with elastic anti-slip pads 10.

[0024] The worktable 2 is provided with a pre-positioning slot 16 and a scale plate 17, with the scale plate 17 located to the side of the pre-positioning slot 16.

[0025] In this embodiment, when it is necessary to make a cut on a branch, the branch is first placed in the pre-positioning groove 16, and the position of the branch is controlled by the scale plate 17 to control and adjust the length of the branch cut. Then, the handle 13 is used to rotate the shaft 3, so that the two threads on the shaft 3 with opposite directions are screwed into the threaded blocks 4 on both sides. Under the guidance of the guide block 15, the first connecting frame 5 and the second connecting frame 14 drive the moving block 6 to move closer to each other. When the clamping plate 9 contacts the branch, the clamping plate 9 will compress the spring 7 through the connecting column 8 to play a buffering role, so as to avoid the clamping plate 9 from abrading the surface of the branch. The guide slider 11 and the stabilizing rod 12 can stabilize and guide the movement of the spring 7 and the connecting column 8. With the help of the elastic anti-slip pad 10, the clamping effect of the branch is fully guaranteed. This not only avoids the problem of not being able to guarantee the stability of the branch when making a cut, but also makes the operation simple and convenient, and it is easy to quickly master the usage method, which has good practicality.

[0026] Example 2

[0027] like Figure 1 and Figure 4 As shown, the grafting branch pretreatment device proposed in this embodiment, compared with the first embodiment, has an installation frame 18 on the base 1, a cutting assembly on the installation frame 18, and the cutting assembly includes a cylinder 19 on the installation frame 18, an installation block 20 driven and connected to the cylinder 19, and a cutting blade 21 on the installation block 20; a warning plate 24 is provided on the installation frame 18.

[0028] The mounting bracket 18 is provided with four uprights 23, and the mounting block 20 is provided with four fixing blocks 22, which are slidably connected to the uprights 23.

[0029] In this embodiment, after the branch is fixed, the cylinder 19 drives the mounting block 20 to descend, so that the cutting blade 21 can make a cut on the branch. The warning plate 24 can also serve as a warning to prevent hands from reaching into the device. At the same time, during the lifting and lowering process, the mounting block 20 can be guided by the fixing block 22 and the upright 23 to ensure the straightness of the cutting blade 21 when it moves.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
