Abstract
Description
Technical Field
[0001] The utility model relates to the field of agricultural planting, in particular to a grafting fixing device used for agronomic planting. Background Art
[0002] Grafting is a plant propagation technique that involves grafting a bud or branch from one plant onto the stem or root of another plant, allowing the scion to grow into a new plant. Grafting technology has many applications in agriculture, including improving fruit tree varieties, increasing crop disease resistance and drought tolerance, increasing yields, and extending the harvest season. The key to grafting is to allow the scion's cambium to adhere closely to the stock's cambium, bringing the cambium layers of the two wound surfaces close together and fixing the scion and stock together. After cell proliferation, the cells heal with each other to form a whole connected by vascular tissue.
[0003] When fixing the scion and the stock together, plastic film is usually used to wrap the grafting interface. However, the fixing effect of the plastic film is not stable. When encountering strong winds and heavy rains, the plastic film may slip or loosen, causing the interface to be exposed, or even causing the scion to detach from the stock, affecting the survival rate of the plant graft. Utility Model Content
[0004] In order to overcome the disadvantage that the existing grafting process uses plastic film for fixation, which will slip when encountering strong winds and heavy rains, thereby affecting the survival rate of the grafting, the utility model provides a grafting fixing device for agronomic planting that can still fix the scion on the rootstock even when encountering strong winds and heavy rains.

[0017] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0018] like Figure 1-3 As shown, a grafting and fixing device for agricultural planting includes an upper fastening sleeve 13, a lower fastening sleeve 1, a film 3, a hinge 6, a sliding sleeve 11 and a sliding rod 12. The upper fastening sleeve 13 is located above the lower fastening sleeve 1, and corresponding blind holes are provided on the lower part of one side of the upper fastening sleeve 13 and the upper part of one side of the lower fastening sleeve 1. A sliding sleeve 11 is provided between the upper and lower blind holes. Sliding rods 12 are slidably inserted into the upper and lower ends of the sliding sleeve 11. The top end of the upper sliding rod 12 is connected to the upper blind hole, and the bottom end of the lower sliding rod 12 is connected to the lower blind hole. The film 3 is wound on the sliding sleeve 11. When the upper and lower sliding rods 12 are controlled to retract into the sliding sleeve 11, the blind holes on the upper fastening sleeve 13 and the lower fastening sleeve 1 can wrap the film 3. The upper fastening sleeve 13 and the lower fastening sleeve 1 are both made of elastic plastic. The other side of the upper fastening sleeve 13 and the lower fastening sleeve 1 is respectively provided with a notch, and one side of the notch of the upper fastening sleeve 13 and the lower fastening sleeve 1 is hinged with a hinge 6, each hinge 6 is provided with a pin, and the other side of the notch of the upper fastening sleeve 13 and the lower fastening sleeve 1 is respectively evenly provided with a plurality of pin holes 7, the upper fastening sleeve 13 is inserted into the corresponding pin hole 7 thereon through the pin thereon, and the lower fastening sleeve 1 is inserted into the corresponding pin hole 7 thereon through the pin thereon, and then the upper fastening sleeve 13 is tightly sleeved on the scion, and the lower fastening sleeve 1 is tightly sleeved on the rootstock.
[0019] Among them, the upper fastening sleeve 13 and the lower fastening sleeve 1 are both arc-shaped sleeves, which can better fit the scion and the rootstock. The inner walls of the upper fastening sleeve 13 and the lower fastening sleeve 1 are both circumferentially installed with air bags 4, and the upper fastening sleeve 13 and the lower fastening sleeve 1 are respectively provided with air inlets connected to the air bags 4 thereon, and rubber plugs 5 are installed on the air inlets. The bottom of the inner wall of the upper fastening sleeve 13 and the top of the inner wall of the lower fastening sleeve 1 are respectively circumferentially installed with sealing rings 8. The bottom end of the upper fastening sleeve 13 is evenly provided with a plurality of locking balls 9 along the circumference, and the top end of the lower fastening sleeve 1 is evenly provided with locking holes 10 corresponding to the locking balls 9 along the circumference. By locking the locking balls 9 into the corresponding locking holes 10, the upper fastening sleeve 13 and the lower fastening sleeve 1 can be connected together.
[0020] When using the grafting fixing device for agricultural planting, the upper fastening sleeve 13 is put on the scion, and the lower fastening sleeve 1 is put on the stock. The connection between the scion and the stock is located between the upper fastening sleeve 13 and the lower fastening sleeve 1. Then, the rubber plug 5 is taken out and the air bag 4 is inflated to expand it. This can prevent the upper fastening sleeve 13 and the lower fastening sleeve 1 from directly contacting the scion and the stock to avoid damaging the surface of the scion and the stock. Then, the upper fastening sleeve 13 and the lower fastening sleeve 1 are manually pressed to reduce the gap on them, and the pin on the hinge 6 is inserted into the corresponding pin hole 7, so that the upper fastening sleeve 13 and the lower fastening sleeve 1 are tightened. The fixing sleeve 13 and the lower fastening sleeve 1 clamp the scion and the stock respectively, and the upper fastening sleeve 13 and the lower fastening sleeve 1 are connected by the sliding rod 12 and the sliding sleeve 11, so that the scion and the stock can be fixed together, and then the film 3 is pulled out to wrap the connection between the scion and the stock to prevent external pathogens from affecting the growth of the scion. The sealing ring 8 on the upper fastening sleeve 13 and the lower fastening sleeve 1 can enhance the sealing between the upper fastening sleeve 13 and the lower fastening sleeve 1 and the scion and the stock, and prevent pathogens from entering the connection between the scion and the stock from the position between the upper fastening sleeve 13 and the lower fastening sleeve 1. When the device is removed from the scion and the rootstock, the upper fastening sleeve 13 and the lower fastening sleeve 1 are manually controlled to move closer to each other. At this time, the slide rod 12 will retract into the slide sleeve 11, and the blind holes on the upper fastening sleeve 13 and the lower fastening sleeve 1 will wrap the film 3. At the same time, the card ball 9 moves downward into the card hole 10 to connect the two fastening sleeves 1 together, which helps to maintain the integrity of the device during storage and ensures that it can perform at its best when in use.
[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
