Description

Technical Field

[0001] The utility model relates to the technical field of walnut cultivation, in particular to a grafting device for high-grafting and re-seeding walnuts. Background Art

[0002] Walnut has high economic value and has broad development prospects as a specialty food. It is generally propagated by grafting. Ordinary walnut seedlings are used as rootstocks, which have the advantages of strong grafting affinity, high survival rate, good growth and fruiting.

[0003] During the grafting process, the rootstock and the scion need to be clamped and fixed. The existing grafting fixing structure is mostly clamped and fixed directly by clamps, which is simple and convenient. However, the size of the clamp is generally fixed. When the clamp is too large, it may not be clamped tightly enough with the rootstock and the scion. If the clamp is too small, the clamp is prone to falling off.

[0004] The existing Chinese patent with announcement number CN218789230U discloses a grafting and fixing structure for red-kernel walnut cultivation, including: a rootstock, a slot is opened on the top of the rootstock; a spike, the bottom end of the spike is inserted into the slot; the outer surface of the top of the rootstock is equipped with a clamping and fixing mechanism; the clamping and fixing mechanism includes two movable bars, the two movable bars are arranged crosswise, and the intersection is equipped with a pin shaft, the ends of the two movable bars are fixedly connected with a limiting spring, the other end of the movable bar is equipped with a connecting bar, and both ends of the connecting bar are fixedly connected with a clamping ring; a snap-on assembly is assembled between the end of the movable bar and the connecting bar.

[0005] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the device clamps and fixes the rootstock, but lacks measures to fix the scion, which needs to be improved; therefore, a walnut high-grafting grafting device is proposed to address the above problems.

[0008] Preferably, the clamping assembly also includes two threaded rods, which are symmetrically threaded on both sides of the clamp. By rotating the threaded rods, clamping frame one and clamping frame two are pushed tightly against the upper and lower branches, thereby improving the stability of clamping the rootstock and scion.

[0009] Preferably, both sides of the clamping frame 1 are respectively provided with slots, and the clamping frame 2 passes through the slots. The clamping frame 2 can pass through the clamping frame 1, which can increase the clamping range of the two.

The upper clamp plate 1 and the lower clamp plate 1 are fixedly connected by an L-shaped connecting column 1, and the upper clamp plate 2 and the lower clamp plate 2 are fixedly connected by an L-shaped connecting column 2.

[0011] Preferably, a locking assembly is installed on the lower card plate one and the lower card plate two, and the locking assembly includes a rotating shaft, one end of the lower card plate two is sleeved on the rotating shaft, and both ends of the rotating shaft are rotatably installed at one end of the lower card plate one, and the lower card plate one and the lower card plate two are rotated to open and close through the rotating shaft, so that the clamp can be sleeved on the outside of the walnut branch, and the lower card plate two inserts the fixing column into the fixing hole through the tension of the spring part, and then the lower card plate one and the lower card plate two are connected, so as to quickly fix the two clamps. When the clamp needs to be removed, press the lower card plate two downward to make the fixing column exit the fixing hole, and the clamp can be quickly opened for easy use.

[0012] Preferably, a spring member is sleeved on the surface of the rotating shaft, and the spring member is located on the second lower clamping plate.
