Abstract
Description
Technical Field
[0001] This application relates to the technical field of agronomic grafting, and in particular to an agronomic grafting fixator. Background Technology
[0002] Agronomic grafting is an agricultural technique that uses artificial methods to attach a branch or bud of one plant to the stem or root of another, combining the two into a new plant. It utilizes the superior characteristics of the rootstock, such as resistance to diseases and pests, tolerance to poor soil, and adaptability to harsh environments, to enhance the growth capacity, yield, and quality of the scion variety. Common grafting methods include branch grafting and bud grafting. Branch grafting is mostly carried out in spring, selecting healthy branches as scions, shaping them appropriately, inserting them into the incision in the rootstock, and binding them in place. Bud grafting uses bud patches as scions and is commonly used during the growing season. It is simple to operate and has a high survival rate. During the grafting process, it is crucial to ensure close contact between the cambium layers of the scion and the rootstock; this is key to successful grafting. Grafting is widely used in fruit trees, vegetables, flowers, and other crops. For example, apples are grafted onto crabapple rootstocks, and watermelons onto pumpkin rootstocks. This method maintains the superior traits of the scion variety while enhancing the plant's adaptability, making it an important technique for improving varieties and increasing efficiency in agricultural production.
[0003] A search revealed Chinese Patent Publication No. CN222786467U, which discloses a grafting fixing device for agronomists, relating to the field of agronomic grafting technology. The device includes an upper fixing ring and a lower fixing mechanism below it. Both the upper and lower fixing rings share an adjustment mechanism, which contains an intelligent control mechanism. The lower fixing mechanism includes a lower fixing ring, with the bottom surface of the upper fixing ring contacting the upper surface of the lower fixing ring. The adjustment mechanism includes two sets of threaded cylinders. The device, consisting of the upper and lower fixing rings, facilitates the fixing of the plant to be grafted using two sets of clamping plates. Multiple pressure sensors on the clamping plates detect the pressure exerted on the plant and adjust the clamping plates accordingly, applying a suitable fixing force to the grafting position for convenient use.
[0004] Regarding the aforementioned technologies, the inventors discovered the following defects: when the two plants to be grafted have different thicknesses or uneven surfaces, the clamping plate cannot effectively fix the plants. Utility Model Content
[0005] In order to solve the problems mentioned in the background art, this application provides an agronomic grafting fixator.
[0006] This application provides an agricultural grafting fixation device, which adopts the following technical solution:
[0007] An agricultural grafting fixing device includes a first fixing half-ring and a second fixing half-ring. The second fixing half-ring is hinged to one side of the first fixing half-ring, and the second fixing half-ring and the first fixing half-ring can form a ring.

[0013] Optionally, the first and second sealing sheets are made of rubber and have openings through their surfaces.
[0014] In summary, this application includes the following beneficial technical effects:
[0015] 1. This utility model uses the rotating screw cap to drive the reinforcing screw to rotate, causing the rubber connecting block to move closer to the graft and apply pressure, thereby enhancing the reinforcement effect. Reverse rotation can release the reinforcement. By rotating the fixing rod cap, the length of the fixing rod extending into the ring can be adjusted to accommodate grafts of different thicknesses, thus fixing the graft and the graft to be grafted separately, thereby adapting to grafting of plants of various thicknesses.
[0016] 2. This utility model uses screws to fix the first and second mounting blocks to the tops of two semi-rings respectively. When the semi-rings are closed, the first and second sealing plates fit together, providing a seal. The sealing plates prevent some rainwater and dust from entering the grafting area, providing a relatively clean and humid environment for the healing of the graft, which is beneficial to improving the graft survival rate. The screw connection method facilitates the disassembly and replacement of the mounting blocks and makes it convenient to maintain or replace the sealing plates. Attached Figure Description

[0027] Please see Figure 1 , 5 Multiple sets of extension blocks 7 are distributed in a ring at the bottom ends of the first fixed half-ring 1 and the second fixed half-ring 2. A second mounting hole 10 is opened through one side of the extension block 7. The inner wall of the second mounting hole 10 is threaded. A reinforcement mechanism 9 is provided in the second mounting hole 10. The reinforcement mechanism 9 includes a reinforcement screw 91, which is threaded into the inside of the second mounting hole 10. A rubber connecting block 92 is fixedly provided on the side of the reinforcement screw 91 near the middle of the first fixed half-ring 1 and the second fixed half-ring 2. A screw cap 93 is fixedly provided on the side of the reinforcement screw 91 away from the rubber connecting block 92. During operation, the reinforcement screw 91 is rotated by rotating the screw cap 93, which makes the rubber connecting block 92 move closer to the graft and apply pressure, thereby enhancing the reinforcement effect. Reverse rotation can release the reinforcement.
[0028] Please see Figure 1 , 2 4. A first mounting block 14 is fastened to the top of the first fixed half-ring 1 by screws, and a second mounting block 15 is fastened to the top of the second fixed half-ring 2 by screws. A first sealing plate 16 is fixedly installed on the side of the first mounting block 14 near the side of the second mounting block 15, and a second sealing plate 17 is fixedly installed on the side of the second mounting block 15 near the side of the first mounting block 14. The first sealing plate 16 and the second sealing plate 17 are made of rubber and have openings through their surfaces.

When the half-rings are closed, the first sealing plate 16 and the second sealing plate 17 fit together to achieve a sealing effect.
[0029] Please see Figure 1 , 23. A second fixed half-ring 2 is hinged to one side of the first fixed half-ring 1, and the second fixed half-ring 2 and the first fixed half-ring 1 can form a ring. An assembly block 3 is fixedly installed on the side of the first fixed half-ring 1 away from the hinge of the second fixed half-ring 2, and a connecting block 4 is fixedly installed on the side of the second fixed half-ring 2 away from the hinge of the first fixed half-ring 1. An installation groove 5 is opened on one side of the assembly block 3 and the connecting block 4, and a locking mechanism 6 is provided inside the installation groove 5. Multiple sets of first mounting holes 8 are distributed in a ring on the side walls of the first fixed half-ring 1 and the second fixed half-ring 2. The inner wall of the first mounting hole 8 is threaded, and a fixing rod 11 is threadedly connected inside the first mounting hole 8. A fixing rod cap 12 is fixedly installed on the end of the fixing rod 11 away from the first fixed half-ring 1 and the second fixed half-ring 2. Multiple sets of extension blocks 7 are distributed in a ring at the bottom of the first fixed half-ring 1 and the second fixed half-ring 2. A second mounting hole 10 is provided through one side of block 7. The inner wall of the second mounting hole 10 is threaded and a reinforcing mechanism 9 is provided in the second mounting hole 10. A rubber ring 13 is fixedly provided on the inner wall of the first fixing half ring 1 and the second fixing half ring 2. The rubber ring 13 has an opening at the corresponding position of the opening of the first fixing half ring 1 and the second fixing half ring 2. During installation, the second fixing half ring 2 is rotated to open or close the two half rings to wrap the grafting part. After the two half rings are closed, they are fixed by the locking mechanism 6. The length of the fixing rod 11 extending into the ring can be adjusted by rotating the fixing rod cap 12 to adapt to grafting bodies of different thicknesses. The rubber ring 13 can deform with the opening and closing of the half rings when the fixer is closed, and fits the surface of the grafting body to reduce wear on the grafting body. Then, the grafting body is locked by the reinforcing mechanism 9 to complete the grafting of the crop.
[0030] The implementation principle of an agronomic grafting fixer according to an embodiment of this application is as follows: During installation, the second fixing half-ring 2 is rotated to open or close the two half-rings to wrap the grafting part. After closing the two half-rings, the locking rod 61 is rotated to make it snap into the mounting groove 5 of the connecting block 4. Then, the locking knob 62 is rotated, and the connecting block 4 is pressed by the gasket 63 to lock the two half-rings. The locking knob 62 can be loosened by rotating it in the opposite direction. The screw cap 93 is rotated to drive the reinforcing screw 91 to rotate, so that the rubber connecting block 92 moves closer to the graft and applies pressure, thereby enhancing the reinforcement effect. The reinforcement can be released by rotating it in the opposite direction. The length of the fixing rod 11 extending into the ring can be adjusted by rotating the fixing rod cap 12 to adapt to grafting bodies of different thicknesses. The rubber ring 13 can deform with the opening and closing of the half-rings when the fixer is closed, and fits the surface of the grafting body to reduce wear on the grafting body.
