Description

Technical Field

[0001] This utility model relates to the field of kiwifruit grafting technology, and in particular to an auxiliary mechanism for kiwifruit grafting. Background Technology

[0002] Kiwi grafting is a cultivation method that involves grafting kiwifruit. Grafted kiwifruit seedlings can be cultivated in spring, summer, and autumn. Grafting methods include: bark grafting, cleft grafting, whip grafting, and bud grafting. When grafting kiwifruit using the cleft grafting method, a grafting knife is first used to cut a groove of a certain depth on one end of the rootstock, and then the scion is inserted into it for grafting. However, when the lengths of the rootstock and scion change, the required cutting depth of the rootstock will also change in order to ensure full contact between the cambium layers of the two, stable survival of the scion, and sufficient nutrients provided by the rootstock. Traditional grafting shears can only cut to the same depth. When the length of the scion changes, cutting too deep will damage the xylem of the rootstock, or cutting too shallow will cause the scion to be unstable, thus affecting the grafting survival rate of the kiwifruit. Summary of the Invention

[0003] Therefore, it is necessary to provide an auxiliary mechanism for kiwi grafting to address the problem that traditional grafting scissors can only cut to the same depth, which can damage the rootstock xylem if the cut is too deep or cause the scion to be unstable if the cut is too shallow.

[0004] An auxiliary mechanism for grafting kiwifruit includes: grafting shears, wherein the grafting shears include a mounting plate, a fixed blade, and a movable blade; An adjustment mechanism is provided, comprising a grafting blade and a locking assembly for locking the extension length of the grafting blade. The grafting blade is slidably disposed inside the mounting plate, and the mounting plate has a mounting groove corresponding to the grafting blade on its side.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined Figures 1-5 This invention describes an auxiliary mechanism for grafting kiwifruit.

[0019] In one embodiment, an auxiliary mechanism for grafting kiwifruit includes: a grafting shear 100, which includes a mounting plate 101, a fixed blade 102, and a movable blade 103; and an adjustment mechanism 200, which includes a grafting blade 201 and a locking component for locking the extension length of the grafting blade 201. The grafting blade 201 is slidably disposed inside the mounting plate 101, and the side of the mounting plate 101 is provided with a mounting groove 207 corresponding to the grafting blade 201. In this embodiment, the grafting shears 100 drive the movable blade 103 closer to the fixed blade 102, thereby pruning the branches through the fixed blade 102 and the movable blade 103. The mounting plate 101 is disposed on the side of the fixed blade 102, and the mounting plate 101 does not contact the movable blade 103. The grafting blade 201 is disposed on the side of the mounting plate 101 away from the movable blade 103, and the grafting blade 201 is slidably disposed inside the mounting groove 207, thereby ensuring that the length of the grafting blade 201 extending from inside the mounting plate 101 can be adjusted, so as to cut grooves of different depths for rootstocks of different lengths.

[0020] like Figure 4 and Figure 5As shown, the snap-fit ​​assembly includes a telescopic sleeve 203, a snap-fit ​​rod 204, a tension spring 209, and a telescopic post 210. The telescopic sleeve 203 is fixedly connected to the grafting blade 201. The telescopic post 210 is slidably disposed inside the telescopic sleeve 203. The tension spring 209 is disposed inside the telescopic sleeve 203 and between the telescopic sleeve 203 and the telescopic post 210. The snap-fit ​​rod 204 is fixedly disposed at the end of the telescopic post 210 away from the telescopic sleeve 203. A snap-fit ​​post is fixedly connected to the end of the telescopic post 210 away from the snap-fit ​​rod 204. The snap-fit ​​post is slidably disposed inside the telescopic sleeve 203. In this embodiment, the diameter of the snap-fit ​​post is larger than the diameter of the telescopic post 210 and smaller than the diameter of the telescopic sleeve 203. Both the snap-fit ​​post and the telescopic post 210 are slidably disposed inside the telescopic sleeve 203. The snap-fit ​​post limits the telescopic post 210, ensuring that the telescopic post 210 can extend and retract inside the telescopic sleeve 203 without completely detaching from the inside of the telescopic sleeve 203. At the same time, one end of the tension spring 209 is fixedly connected to the snap-fit ​​post, and the other end of the tension spring 209 is fixedly disposed inside the telescopic sleeve 203, thereby driving the telescopic post 210 to move into the telescopic sleeve 203, which in turn drives the snap-fit ​​rod 204 to move into the telescopic sleeve 203.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the upper surface of the mounting plate 101 is provided with several sets of snap-fit ​​grooves 206 corresponding to the snap-fit ​​rod 204, and the upper surface of the mounting plate 101 is provided with a first moving groove 205 corresponding to the snap-fit ​​rod 204. The first moving groove 205 is connected to several sets of snap-fit ​​grooves 206. Adjusting blocks 208 are fixedly provided on both sides of the grafting blade 201, and an adjusting groove 202 corresponding to the adjusting block 208 is provided on the inner side of the mounting groove 207. In this embodiment, the locking rod 204 slides inside the first moving groove 205 and the locking groove 206. When the locking rod 204 is inside the locking groove 206, it is locked inside the locking groove 206 under the action of the tension spring 209, thereby locking and fixing the grafting blade 201. When it is necessary to adjust the extension length of the grafting blade 201, the locking rod 204 is pulled into the first moving groove 205 and then moved along the first moving groove 205 to the corresponding locking groove 206, which facilitates the adjustment of the extension length of the grafting blade 201 and ensures the stability of the grafting blade 201 when cutting the rootstock.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, the moving mechanism 300 includes a moving column 301 and a support plate 303. The support plate 303 is slidably disposed on one side of the mounting plate 101. The moving column 301 is connected to the movable blade 103. A protective cover 304 is fixedly disposed on one side of the mounting plate 101. The support plate 303 is slidably disposed inside the protective cover 304. The moving column 301 slides through the mounting plate 101. A second moving groove 302 corresponding to the moving column 301 is opened on the side of the mounting plate 101. The moving column 301 is located below the support plate 303. A limit block 305 is provided on the side of the support plate 303 near the mounting plate 101, and the limit block 305 is slidably disposed inside the mounting plate 101. In this embodiment, when the movable blade 103 moves, it drives the movable column 301 to move. The second movable groove 302 is opened to ensure the stability of the grafting blade 201 during the movement process. When the movable blade 103 drives the movable column 301 to move, the movable column 301 pushes the support plate 303 upward, and the support plate 303 moves along the mounting plate 101 through the side limiting block 305, thereby ensuring the stability of the support plate 303 during the movement process. Thus, when the fixed blade 102 and the movable blade 103 come into contact, the grafting blade 201 will simultaneously come into contact with the support plate 303, thereby cutting the rootstock on the surface of the support plate 303 through the grafting blade 201.

[0023] Working principle: When the lengths of the rootstock and scion change, the clamping rod 204 is pulled into the first moving groove 205, and the length of the grafting blade 201 extending from the mounting plate 101 is adjusted. Then, the clamping rod 204 is slid into the corresponding clamping groove 206. At this time, the tension spring 209 drives the telescopic column 210 to move into the telescopic sleeve 203, thereby causing the clamping rod 204 to engage in the clamping groove 206, thus ensuring the stability of the grafting blade 201 during cutting. Then, the rootstock is placed on the surface of the support plate 303, and the movable blade 103 drives the support plate 303 to move towards the grafting blade 201, thereby cutting and slotting the rootstock with the grafting blade 201. This ensures that scions of different lengths can be inserted into the corresponding grooves, ensuring full contact between the cambium layers of the scion and rootstock, stable survival of the scion, and sufficient nutrients provided by the rootstock.
