Description

Technical Field

[0001] This utility model relates to the field of citrus grafting, and in particular to a citrus grafting rootstock cutting tool. Background Technology

[0002] In the process of citrus grafting, the cutting of the rootstock is a key step. Traditional citrus grafting rootstock cutting often requires the use of a variety of different tools, such as a girdling knife for girdling the rootstock, a chopping knife for cleft grafting, and a knife for oblique cutting of the side of the rootstock.

[0003] In practice, workers need to frequently change different tools, which not only wastes a lot of time but also reduces grafting efficiency. Carrying multiple tools increases the complexity and labor intensity of the operation. Therefore, a cutting tool that integrates functions such as rootstock ring cutting, end chopping, and side beveling is needed to solve the problems existing in the current technology.

[0043] In the preferred embodiment, the back of the blade of the flipping blade 505 is also provided with a protrusion 509, which makes it easier for workers to flip the flipping blade 505.

[0044] The tool holder 503 has protective plates on both sides, and a placement groove 504 is provided between the protective plates for placing the flipping blade 505.

[0045] In the preferred embodiment, the limiting plate 507 is also provided with a locking groove 508 on the side facing the fixing part 2. The locking groove 508 is used to cooperate with the fixing blade 4 to clamp the anvil, making it convenient for workers to perform circumferential cutting.

[0046] The circumferential cutting part 6 has a blade groove 602 on the side facing the limiting plate 507, and a through pin hole 601 on one side of the blade groove 602. The blade groove 602 is used to install and fix the blade 4, and the pin hole 601 is used to install a pin to limit and fix the blade 4.

[0047] The specific implementation process of a citrus grafting rootstock cutting tool is as follows:

[0048] Cleft grafting: The operator holds the rubber handle 101 of the main rod 1, with the anti-slip groove 103 facing to one side of the body for stability, and aligns the chopping part 3 with the oblique blade head with the cross-section of the rootstock, and applies vertical downward force to chop, using the sharp edge of the chopping part 3 to split the end of the rootstock flat, forming a split about 3-5 cm deep, in preparation for the subsequent insertion of the scion.

[0049] Beveling method: Keep the main rod 1 stable, loosen the locking bolt 502 to disengage the pressure plate 511 from the anti-slip groove 103, and slide the movable part 5 along the anti-slip groove 103 to a suitable position. The flipping blade 505 is rotated out of the placement groove 504 by the rotating pin 506 until the backing plate 510 is in contact with the limiting plate 507. At this time, the strong magnet attracts and fixes the flipping blade 505. Use the flipping blade 505 to cut the lower end of the scion into a wedge-shaped bevel, the length of which matches the depth of the rootstock split.

[0050] Quickly insert the prepared scion into the cleft of the rootstock, ensuring the cambium layers are aligned, to complete the cleft grafting operation. After the operation is complete, rotate the flipping blade 505 back into the placement slot 504.

[0051] Ring-cutting branches: Install the pin to fix the blade 4 through the pin hole 601, so that the V-shaped cut 401 is tightly against the outer circle of the rootstock branch. The limiting plate 507 of the sliding movable part 5 contacts the other side of the branch, and the locking groove 508 and the fixing blade 4 form a ring-shaped structure around the branch. Rotate the main rod 1 along the circumference of the branch, and use the sharp edge of the fixing blade 4 to complete the ring-cutting of the branch.

[0052] After girdling, continue to apply pressure to make the fixed blade 4 cut into the xylem of the branch until the branch is completely cut off, and obtain a rootstock segment of suitable length.

[0053] Side treatment of the rootstock: Slide the movable part 5 to the side of the rootstock where the cut is to be made, so that the flipping blade 505 forms a 30-45 degree angle with the side of the rootstock.

[0054] The flipping blade 505 maintains a stable angle under the restriction of the limiting plate 507, and makes a slanted cut on the side of the rootstock to form a cut with a depth of about 1-2 cm.

[0055] Use the flipping blade 505 to cut the lower end of the scion into a matching bevel, quickly align the bevel of the scion with the cut of the rootstock to complete the bevel grafting. After the operation is completed, turn the flipping blade 505 back into the placement slot 504 and use the protective plate to protect the blade.

[0056] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
