Description

Technical Field

[0001] This utility model relates to the field of seedling grafting technology, and in particular to a vegetable seedling grafting device. Background Technology

[0002] Grafting is a common plant propagation technique that can improve a plant's disease resistance, cold tolerance, drought tolerance, as well as increase crop yield and quality. Vegetable seedling grafting devices are mechanical equipment used in agricultural planting. Their main function is to combine two different vegetable plants through surgical methods, allowing them to grow together.

[0003] Traditional seedling grafting devices are usually of a fixed size when cutting and clamping, which makes it inconvenient to change the clamping blocks to fit different stem thicknesses, and also makes it inconvenient to bring them into the greenhouse for cutting.

[0004] Therefore, those skilled in the art have provided a vegetable seedling grafting device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a vegetable seedling grafting device. Pulling the insertion rod away from the protrusion releases the locking mechanism, and the protrusion is removed from the groove, making it easy to replace the clamping blocks with those suitable for different stem thicknesses. When installing a new clamping block, the operation is reversed. The vegetable seedling is placed in the clamping ring and is pressed and fixed by the second spring and the clamping ring to prevent it from falling off during pruning and to ensure the stability of the fixation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vegetable seedling grafting device includes a rotating column, a locking mechanism on one side of the rotating column, and a clamping mechanism on one side of the locking mechanism. The locking mechanism includes two insert rods. A first rotating ring is rotatably connected to the upper end of the outer wall of the rotating column, and a second rotating ring is rotatably connected to the lower end of the outer wall of the rotating column. A first clamping block and a second clamping block are respectively fixedly connected to one side of the first rotating ring and the second rotating ring. A protrusion is fixedly connected to the upper end of the other side of the first clamping block and the lower end of the other side of the second clamping block. A groove is formed at the front of the upper end of the first rotating ring and the rear of the lower end of the second rotating ring. The two insert rods are located inside the grooves. A connecting block is fixedly connected to the end of the two insert rods away from the center of the rotating column. A first damping rod is fixedly connected to both sides of the end of the two connecting blocks near the center of the rotating column. A first spring is sleeved on the outer wall of a plurality of first damping rods.

[0008] Using the above technical solution, pull the insert rod away from the protrusion to disengage it from the protrusion, then move the protrusion away from the groove and replace it with a clamping block that is suitable for different stem diameters. When installing a new clamping block, simply reverse the operation.

[0009] Furthermore, the first clamping block and the second clamping block each have multiple cavities at one end near the center of the rotating column, and a second damping rod is fixedly connected to one end of each cavity away from the center of the rotating column. A second spring is sleeved on the outer wall of each of the multiple second damping rods, and a clamping ring is fixedly connected to one end of each adjacent second damping rod near the center of the rotating column.

[0010] The above technical solution places the vegetable seedlings between the clamping rings, and the second spring and the clamping rings squeeze them to prevent the seedlings from falling off during pruning, ensuring the fixation effect and avoiding mechanical damage.

[0011] Furthermore, a first connecting rod and a second connecting rod are respectively fixedly connected to the other side of the first rotating ring and the second rotating ring;

[0012] The above technical solution enhances the stability of the entire device, making it less prone to displacement of the rotating ring during operation, thereby maintaining the accuracy of cutting and clamping.

[0013] Furthermore, a cutting blade is fixedly connected to one end of both the first clamping block and the second clamping block near the center of the rotating column;

[0014] The above technical solution allows for cutting while holding the plant, ensuring accurate cutting and improving the success rate of grafting.

[0015] Furthermore, both of the aforementioned inserts penetrate the protrusion to the outside of the protrusion;

[0016] The above technical solution allows the insertion rod to penetrate the protrusion, making the structure of the clamping device more stable and reducing component displacement caused by vibration during operation.

[0017] Furthermore, both of the protrusions engage with the grooves;

[0018] The above technical solution ensures a tight connection between the protrusion and the groove, reduces relative movement, and improves overall stability.

[0019] Furthermore, one end of the first damping rod near the center of the rotating column is fixedly connected to the first rotating ring and the second rotating ring, respectively.

[0020] The above technical solutions reduce swaying during operation and improve operational accuracy.

[0021] Furthermore, multiple second damping rods slide on the inner wall of the cavity;

[0022] Through the above technical solution, multiple second damping rods can evenly distribute pressure, avoiding damage to seedlings caused by excessive local pressure.

[0023] This utility model has the following beneficial effects:

[0024] 1. This utility model proposes a vegetable seedling grafting device. Pulling the insertion rod away from the protrusion releases the engagement with the protrusion. Then, the protrusion is moved away from the groove to replace the clamping block with one suitable for different stem thicknesses. When installing a new clamping block, only the reverse operation is required. The engagement can be released by a simple push-pull action without the need for tools, realizing the quick disassembly and installation of the clamping block and improving the replacement efficiency. The vegetable seedling is placed between the clamping rings, and the second spring and the clamping rings compress it to prevent the vegetable seedling from falling off during pruning, ensuring the fixing effect and avoiding mechanical damage.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides a specific embodiment: a vegetable seedling grafting device, including a rotating column 5, a locking mechanism 1 on one side of the rotating column 5, and a clamping mechanism 2 on one side of the locking mechanism 1. The locking mechanism 1 includes two insert rods 107. A first rotating ring 103 is rotatably connected to the upper end of the outer wall of the rotating column 5, and a second rotating ring 104 is rotatably connected to the lower end of the outer wall of the rotating column 5. A first clamping block 101 and a second clamping block 102 are respectively fixedly connected to one side of the first rotating ring 103 and the second rotating ring 104. The first clamping block 101... On the other side, the upper end and the lower end of the second clamping block 102 are both fixedly connected to the protrusion 106. The front part of the upper end of the first rotating ring 103 and the rear part of the lower end of the second rotating ring 104 are both provided with grooves 105. The two insert rods 107 are both located inside the grooves 105. The end of the two insert rods 107 away from the center of the rotating column 5 is fixedly connected to the connecting block 108. The two sides of the end of the two connecting blocks 108 near the center of the rotating column 5 are both fixedly connected to the first damping rods 109. The outer walls of the multiple first damping rods 109 are all fitted with first springs 110.

[0038] Pull the insert rod 107 away from the protrusion 106 to disengage it from the protrusion 106. Then move the protrusion 106 away from the groove 105 and replace it with a clamping block that fits a different stem diameter. When installing a new clamping block, simply reverse the operation.

[0039] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7Multiple cavities 201 are provided at the ends of the first clamping block 101 and the second clamping block 102 near the center of the rotating column 5. A second damping rod 202 is fixedly connected to the ends of the multiple cavities 201 away from the center of the rotating column 5. A second spring 203 is sleeved on the outer wall of the multiple second damping rods 202. A clamping ring 204 is fixedly connected to the ends of adjacent second damping rods 202 near the center of the rotating column 5. When vegetable seedlings are placed between the clamping rings 204, the second springs 203 and the clamping rings 204 compress them to prevent the vegetable seedlings from falling off during pruning, ensuring the fixing effect and avoiding mechanical damage. A first connecting rod 3 and a second connecting rod 4 are fixedly connected to the other side of the first rotating ring 103 and the second rotating ring 104, respectively, to enhance the stability of the entire device and make it difficult for the rotating rings to shift during operation, thereby maintaining the accuracy of cutting and clamping. A cutting blade 6 is fixedly connected to the ends of the first clamping block 101 and the second clamping block 102 near the center of the rotating column 5.

[0040] Cutting can be performed while clamping the plant, ensuring accurate cutting position and improving grafting success rate. Both insertion rods 107 penetrate through the protrusion 106 to the outside of the protrusion 106, making the clamping device structure more stable and reducing component displacement due to vibration during operation. Both protrusions 106 engage with the groove 105, ensuring a tight connection between the protrusion 106 and the groove 105, reducing relative movement and improving overall stability. One end of the adjacent first damping rod 109 near the center of the rotating column 5 is fixedly connected to the first rotating ring 103 and the second rotating ring 104 respectively, reducing swaying during operation and improving operational accuracy. Multiple second damping rods 202 slide on the inner wall of the cavity 201, which can evenly distribute pressure and avoid seedling damage caused by excessive local pressure.

[0041] Working principle: Pull the insert rod 107 away from the protrusion 106 to disengage it from the protrusion 106. Then move the protrusion 106 away from the groove 105 and replace it with a clamping block that fits a different stem thickness. When installing a new clamping block, insert the protrusion 106 into the inner wall of the groove 105. The insert rod 107 is squeezed and moves towards the outer wall until the protrusion 106 is completely inside the groove 105. The insert rod 107 passes through the protrusion 106 under the elastic force of the first spring 110. The quick disassembly and installation of the clamping block improves the replacement efficiency. Place the vegetable seedling between the clamping rings 204. The second spring 203 and the clamping rings 204 squeeze it to prevent the vegetable seedling from falling during pruning and ensure the fixing effect. At the same time, this device is small in size and can be easily carried into the vegetable seedling greenhouse for grafting and cutting.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
