Description

Technical Field

[0001] The utility model belongs to the technical field of walnut tree grafting tools, in particular to a fixing clamp for walnut tree grafting. Background Art

[0002] Walnut tree grafting is an important agricultural technique for promoting walnut tree growth and improving varieties. Walnut tree grafting is typically performed in spring and autumn. Spring grafting should be performed after the plant begins to bud, which promotes growth; autumn grafting should be performed before the leaves fall. Specifically, walnut branch grafting can be performed around the time the sap begins to flow, generally around five days before the beginning of spring. Bud grafting, on the other hand, can only be performed after the sap begins to flow and the bark can be peeled off, a slightly later time than branch grafting.

[0003] During the grafting process of walnut trees, a fixing clamp is required. However, the existing fixing clamp for walnut tree grafting is not convenient for adjusting the height and direction of the graft fixing frame, and is therefore not suitable for grafting grafts at different angles and lengths grafted onto the main branch. Utility Model Content

[0004] The utility model provides a fixing clamp for walnut tree grafting, aiming to solve the problem in the above-mentioned background technology that the existing fixing clamp for walnut tree grafting is not convenient for adjusting the height and direction of the grafting branch fixing frame and cannot be applied to grafting branches grafted on the main branch at different angles and lengths.

[0005] To solve the above problems, the utility model is implemented as follows: a fixing clamp for walnut tree grafting, comprising: a mounting plate; two positioning plates and two side plates fixedly mounted on the mounting plate; a horizontal axis rotatably mounted on one side of the two side plates close to each other; a rotating plate fixedly sleeved on the horizontal axis; a height adjustment mechanism mounted on the rotating plate, the height adjustment mechanism being used to adjust the clamping and fixing height of the grafted branch; an angle adjustment mechanism mounted on the mounting plate, the angle adjustment mechanism being used to adjust the clamping and fixing angle of the grafted branch; two clamping and fixing mechanisms respectively mounted on the mounting plate and the height adjustment mechanism, the two clamping and fixing mechanisms being used to clamp and fix the main branch and the grafted branch.

[0006] Preferably, the height adjustment mechanism includes: a sliding sleeve fixedly mounted on the rotating plate; a rotating rod rotatably mounted on the inner wall of the sliding sleeve; a threaded block fixedly mounted on the rotating rod; a threaded sleeve threadedly sleeved on the threaded block and slidably connected to the inner wall of the sliding sleeve; and an L-shaped plate fixedly mounted on the threaded sleeve.

[0007] Preferably, a rotating shaft is rotatably mounted on the sliding sleeve, and bevel gears are fixedly mounted on both the rotating shaft and the rotating rod, and the two bevel gears are meshed with each other.

[0008] Preferably, a plurality of limiting grooves are provided on the inner wall of the sliding sleeve, a plurality of limiting blocks are fixedly mounted on the threaded sleeve, and the plurality of limiting blocks are respectively slidably connected to the inner walls on both sides of the plurality of limiting grooves.

[0009] Preferably, the angle adjustment mechanism includes: a worm rotatably mounted on the two positioning plates; and a worm wheel fixedly sleeved on the transverse axis and meshing with the worm.

[0010] Preferably, the clamping and fixing mechanism includes: two vertical plates fixedly mounted on the mounting plate; a bidirectional screw rotatably mounted on the two vertical plates; two sliding plates threadedly sleeved on the bidirectional screw; and arc-shaped clamping plates respectively fixedly mounted on the two sliding plates.

[0011] Preferably, buffer pads are provided on the inner walls of the multiple arc-shaped clamping plates, multiple limit rods are fixedly installed on the side where the multiple vertical plates are close to each other, and the multiple limit rods are slidingly connected to the multiple sliding plates respectively, and knobs are fixedly installed on one end of the rotating shaft, worm gear and the two bidirectional screws.

[0012] Compared with the related art, the fixing clamp for walnut tree grafting provided by the utility model has the following beneficial effects:

[0013] Compared with the existing technology, the walnut tree grafting fixing clamp provided by this solution has a mounting plate as the basic supporting structure of the entire fixing clamp, which firmly carries all other components and ensures the stability and reliability of the entire device. Two positioning plates are fixedly mounted on the mounting plate for installing the angle adjustment mechanism. The horizontal axis is rotatably mounted on the side where the two side plates are close to each other. This design enables the rotating plate to rotate around the horizontal axis, thereby realizing the adjustment of the clamping angle of the grafted branch. The rotating plate is fixedly sleeved on the horizontal axis, which serves as a mounting platform for the height adjustment mechanism and the clamping and fixing mechanism, providing stable support for these mechanisms. The height adjustment mechanism is mounted on the rotating plate, and by adjusting its height, the clamping and fixing of the grafted branch can be realized. The precise adjustment of the fixed height allows the fixing clamp to adapt to grafts of different lengths, improving its versatility and practicality. The angle adjustment mechanism is installed on the mounting plate. It cooperates with the rotating plate to further adjust the clamping angle of the graft. This design allows the fixing clamp to flexibly adjust the clamping angle of the graft according to different grafting requirements, thereby improving the success rate and survival rate of grafting. The two clamping and fixing mechanisms are respectively installed on the mounting plate and the height adjustment mechanism. They are used to clamp and fix the main branch and grafted branch. These mechanisms use a reliable clamping mechanism to ensure that the grafted branch will not loosen or fall off during the grafting process, thereby ensuring the stability and success rate of the grafting.

[0014] In summary, the walnut tree grafting fixing clamp described in the present invention realizes efficient and stable clamping and fixing of the grafted branches during the walnut tree grafting process by integrating key components such as the mounting plate, positioning plate, side plate, horizontal axis, rotating plate, height adjustment mechanism, angle adjustment mechanism and clamping and fixing mechanism. The fixing clamp not only improves the success rate and survival rate of grafting, but also reduces the labor intensity and operation difficulty during the grafting process, providing strong technical support for the variety improvement and efficient cultivation of walnut trees.
