Description

Technical Field

[0001] The utility model relates to the technical field of seedling grafting, in particular to an agricultural seedling grafting device. Background Technique

[0002] Grafting seedlings is a main method in the breeding technology of garden plants. It is a method of artificially combining the branches or buds of the mother plant with excellent traits with another plant body. After healing and growing, it forms an independent and complete individual. The branches or buds used for grafting are called scions, and the plant that receives the scion is called the rootstock. The seedlings cultivated by the grafting method are called grafted seedlings. When two plant species with affinity are grafted, the callus produced by the cambium of the wounds of the rootstock and scion combines with each other, fills the gap between the scion and the rootstock, communicates the two conducting tissues, ensures the up-and-down and mutual conduction of water and nutrients, and forms a new unified body.

[0003] After retrieval, the existing Chinese patent publication number is CN220712152U. This utility model provides a seedling grafting device, including a fixed box. There are clamping holes on the bottom surface of the fixed box. A threaded rod is arranged inside the fixed box, and a fixed cone is fixedly installed at the bottom end of the threaded rod; a rotating assembly is arranged on the outer wall surface of the threaded rod for adjusting the fixing position to clamp and fix at more different angles. By setting the fixed cone, the device itself can be fixed, and the probability of the device being displaced by external force is reduced as much as possible. Position changes are very likely to affect the survival probability of grafted plants. By setting the rotating block, through the cooperation between the rotating block and the rotating sleeve, the device can be clamped and fixed at more different angles, which is convenient for stabilizing the interface when grafting irregular branches and buds. The position of the threaded rod and the fixed cone can be limited by the fixed ring.

[0004] However, in the prior art, after grafting the branches of a tree, it is necessary to support the grafting part to avoid loosening and breaking of the grafting part. When supporting it, a splint is usually used to clamp the grafting part. However, most splints have fixed specifications and cannot adapt to branches of different thicknesses, and the fixing effect is poor when in use. A solution is proposed to solve the problems raised in the above background technique. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides an agricultural seedling grafting device, aiming to improve the problem that after grafting the branches of a tree, it is necessary to support the grafting part to avoid loosening and breaking of the grafting part. When supporting it, a splint is usually used to clamp the grafting part. However, most splints have fixed specifications and cannot adapt to branches of different thicknesses, and the fixing effect is poor when in use.

[0006] To achieve the above object, the utility model adopts the following technical solutions: It includes a fixed block, and both sides of one side of the fixed block are slidably connected with clamping plates. One ends of the two clamping plates are fixedly connected with fixed frames. One side of each of the two fixed frames is threadedly connected with a threaded rod. One ends of the two threaded rods are rotatably connected with moving rods. Both sides and the middle of the two clamping plates are slidably clamped with clamping rods. Through holes are opened in the middle of the six clamping rods.

Then, place the grafting part between the clamping rods. Then, rotate the second knob to drive the bidirectional lead screw to rotate, and drive the two clamping plates to move closer to each other. When the clamping rod touches the outside of the tree branch, the clamping rod will slide inside the clamping plate, so that the ends of each clamping rod can fit on the outer surface of the tree branch. Then, rotate the first knob to drive the threaded rod to move outward, so that the fastening plate on the moving rod moves outward, and the side of the fastening plate firmly fits with the clamping rod. And a rubber pad is arranged on the side of the fastening plate, which can effectively limit and fix the clamping rod after fitting. By this method, the device can adjust the position of the clamping rod according to the thickness of the tree branch when clamping and fixing the grafting part, so that the end of the clamping rod can fit more closely with the outside of the grafting part, and it is more firm after clamping, and the device can adapt to tree branches of different diameters.

[0008] Preferably, an installation block is arranged on one side of the fixed block, and a gear is rotatably connected inside the installation block.

[0009] As a further description of the above technical solution: The installation block can be used to install the gear, and the gear will also rotate when the fixed block is rotated.

[0010] Preferably, the other side of the gear is fixedly connected with one side of the fixed block, and an installation groove is opened above the inside of the installation block.

[0022] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0023] 1. In the present utility model, when supporting the grafting part of a tree branch, first rotate the first knob to drive the threaded rod to rotate and move inwards. After the threaded rod moves, it can push the moving rod to move inwards, causing the fastening plate on the moving rod to move accordingly and separate from the side surface of the clamping rod. Subsequently, place the grafting part between the clamping rods, and then rotate the second knob to drive the bidirectional lead screw to rotate, driving the two clamping plates to move closer to each other. When the clamping rod contacts the outside of the tree branch, the clamping rod will slide inside the clamping plate, enabling the ends of each clamping rod to fit against the outer surface of the tree branch. Then rotate the first knob to drive the threaded rod to move outwards, causing the fastening plate on the moving rod to move outwards and the side surface of the fastening plate to firmly fit against the clamping rod. Moreover, a rubber pad is provided on the side surface of the fastening plate, which can effectively limit and fix the clamping rod after fitting. By this method, the device can adjust the position of the clamping rod according to the thickness of the tree branch when clamping and fixing the grafting part, enabling the ends of the clamping rods to fit more closely to the outside of the grafting part and making the clamping more secure, so that the device can adapt to tree branches of different diameters.

[0024] 2. In the present utility model, by rotating the fixed block clockwise, when the device clamps and supports the tree branch, the angle of the clamping rod can be adjusted to match the angle of the tree branch, making the device more convenient to use. The specific operation is that when rotating the fixed block, the gear fixed inside the fixed block will also rotate accordingly. After rotation, the latch rod on the gear will be forced to lift, causing the end of the latch rod to slide out of the tooth groove on the gear. When the latch rod is lifted, the return spring on the side of the latch rod will be deformed and twisted, and will reset when the end of the latch rod reaches the next tooth groove, driving the end of the latch rod to move downwards and re-engage in the tooth groove. By this method, when the fixed block rotates, the rotated angle can be self-fixed, and there will be no easy deviation after use, making the device more convenient to use.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figures 1 to 3 As shown, an embodiment provided by the present invention includes a fixed block 1. Both sides of one side of the fixed block 1 are slidably connected with clamping plates 2. One end of each of the two clamping plates 2 is fixedly connected with a fixed frame 4. One side of each of the two fixed frames 4 is threadedly connected with a threaded rod 5. One end of each of the two threaded rods 5 is rotatably connected with a moving rod 20. Both sides and the middle of the two clamping plates 2 are slidably clamped with clamping rods 3. Hole grooves 19 are opened in the middle of the six clamping rods 3. The outer surface of one of the moving rods 20 is slidably connected with the inside of three of the hole grooves 19 respectively, and the outer surface of the other moving rod 20 is slidably connected with the inside of the other three hole grooves 19 respectively. Tightening plates 18 are fixedly connected to the outer surfaces of the two moving rods 20 evenly. A bidirectional lead screw 16 is rotatably connected inside the fixed block 1. Both sides of the outer surface of the bidirectional lead screw 16 are threadedly connected with one side of the two clamping plates 2 respectively. One end of each of the two threaded rods 5 is fixedly connected with a first knob 25. One end of the bidirectional lead screw 16 penetrates through one side of the fixed block 1 and is fixedly connected with a second knob 17.

[0033] In this embodiment, when supporting the grafting part of the branch, first rotate the first knob 25 to drive the threaded rod 5 to rotate and move inward. After the threaded rod 5 moves, it can push the moving rod 20 to move inward, causing the fastening plate 18 on the moving rod 20 to move accordingly and separate the fastening plate 18 from the side of the clamping rod 3. Then place the grafting part between the clamping rods 3. Subsequently, rotate the second knob 17 to drive the bidirectional lead screw 16 to rotate and drive the two clamping plates 2 to move closer to each other. When the clamping rod 3 contacts the outside of the branch, the clamping rod 3 will slide inside the clamping plate 2, enabling the ends of each clamping rod 3 to fit against the outer surface of the branch. Then rotate the first knob 25 to drive the threaded rod 5 to move outward, causing the fastening plate 18 on the moving rod 20 to move outward and the side of the fastening plate 18 to firmly fit against the clamping rod 3. Moreover, a rubber pad is provided on the side of the fastening plate 18, which can effectively limit and fix the clamping rod 3 after fitting. By this method, the device can adjust the position of the clamping rod 3 according to the thickness of the branch when clamping and fixing the grafting part, enabling the ends of the clamping rod 3 to fit more closely to the outside of the grafting part, making the clamping more firm and enabling the device to adapt to branches of different diameters.

[0034] Embodiment 2, as Figure 1 and Figure 4 shown, on one side of the fixed block 1, there is an installation block 6. Inside the installation block 6, there is a rotatably connected gear 21. The other side of the gear 21 is fixedly connected to one side of the fixed block 1. Above the inside of the installation block 6, there is an installation groove 24. Inside the installation groove 24, there is a rotatably connected snap rod 22. One side of the snap rod 22 is fixedly connected to a return spring 23. The other end of the return spring 23 is fixedly connected to one side of the installation groove 24. One side of the installation block 6 is fixedly connected to an installation plate 7. The lower end of the installation plate 7 is rotatably connected to an installation disk 8. Four first telescopic rods 9 are rotatably connected around the installation disk 8. The outer surfaces of the four first telescopic rods 9 are all slidably connected to second telescopic rods 11. Around the lower part of the installation disk 8, there are telescopic cylinders 10 provided. The two ends of the four telescopic cylinders 10 are respectively rotatably connected to the two sides of the four second telescopic rods 11. On one side of each of the four second telescopic rods 11, there is a chute 12. On one side of each of the four first telescopic rods 9, there is a slide rod 13 fixedly connected. The outer surfaces of the four slide rods 13 are all threadedly connected with fastening rings 14. The outer surfaces of the four slide rods 13 are respectively slidably connected to the inside of the four chutes 12. The lower ends of the four second telescopic rods 11 are all fixedly connected to puncture rods 15.

[0035] In this embodiment, by rotating the fixing block 1 clockwise, when the device clamps and supports the branch, the angle of the clamping rod 3 can be adjusted to match the angle of the branch, making the device more convenient to use. The specific operation is that when rotating the fixing block 1, the gear 21 fixed inside the fixing block 1 will also rotate accordingly. After rotation, the buckle rod 22 on the gear 21 will be forced to lift, causing the end of the buckle rod 22 to slide out of the tooth groove on the gear 21. When the buckle rod 22 is lifted, the return spring 23 on the side of the buckle rod 22 will be deformed and twisted, and will reset when the end of the buckle rod 22 reaches the next tooth groove, driving the end of the buckle rod 22 to move downward so that the end is re-engaged in the tooth groove. By this method, when the fixing block 1 rotates, the rotated angle can be fixed by itself, and there will be no easy deviation after use, making the device more convenient to use.

[0036] Working principle: Now, by rotating the fixed block 1 clockwise, the angle of its clamping rod 3 is adjusted to match the angle of the branch, making the device more convenient to use. Specifically, when rotating the fixed block 1, the gear 21 fixed inside the fixed block 1 will also rotate accordingly. After rotation, the buckle rod 22 on the gear 21 will be forced to lift, causing the end of the buckle rod 22 to slide out of the tooth groove on the gear 21. When the buckle rod 22 is lifted, the return spring 23 on the side of the buckle rod 22 will deform and twist, and reset when the end of the buckle rod 22 reaches the next tooth groove, driving the end of the buckle rod 22 to move downward so that its end is re-engaged in the tooth groove. Subsequently, rotate the first knob 25 to drive the threaded rod 5 to rotate and move inward. After the threaded rod 5 moves, it can push the moving rod 20 to move inward, causing the fastening plate 18 on the moving rod 20 to move accordingly and separate from the side of the clamping rod 3. Then, place the grafting part between the clamping rods 3. Subsequently, rotate the second knob 17 to drive the bidirectional lead screw 16 to rotate, and drive the two clamping plates 2 to move closer to each other. When the clamping rod 3 contacts the outside of the branch, the clamping rod 3 will slide inside the clamping plate 2, so that the ends of each clamping rod 3 can fit on the outer surface of the branch. Then, rotate the first knob 25 to drive the threaded rod 5 to move outward, causing the fastening plate 18 on the moving rod 20 to move outward, and making the side of the fastening plate 18 firmly fit with the clamping rod 3. Moreover, a rubber pad is provided on the side of the fastening plate 18, which can effectively limit and fix the clamping rod 3 after fitting. Subsequently, adjust the lengths of the first telescopic rod 9 and the second telescopic rod 11 according to the height of the grafting site. The specific steps are as follows: First, bend the second telescopic rod 11 upward so that the lower parts of the four second telescopic rods 11 are separated from each other to increase the support area at the bottom. When bending, the telescopic cylinder 10 on the side of the second telescopic rod 11 will also move and extend accordingly to position the bent second telescopic rod 11. Then, rotate the fastening ring 14 to release the limit on the sliding rod 13, and then pull down each second telescopic rod 11 so that the piercing rod 15 at the lower end of the second telescopic rod 11 is inserted into the soil. After the adjustment is completed, the fastening ring 14 can be tightened again to limit the sliding rod 13 to fix the position of the adjusted second telescopic rod 11.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
