Description

Technical Field

[0001] The utility model relates to the technical field of plant grafting, in particular to an opening device for grafting and planting ancient tea trees. Background Art

[0002] Tea trees with a root diameter of more than 1 cm can be selected for grafting. Tea gardens nearby or where fine yellow loam can be taken can be used for grafting. Deep plowing and fertilization should be carried out one month before grafting to allow the tea tree roots to accumulate sufficient nutrients. Grafting has four steps: cutting the rootstock, splitting the rootstock, cutting the spike, and cutting the spike.

[0003] When implementing this technical solution, there are at least the following defects: the existing tea tree grafting usually uses a knife to make an opening at the tea tree grafting site, but the opening depth cannot be controlled according to the thickness of the grafted seedling, thereby affecting the grafting survival efficiency of the tea tree, and it is urgently needed to be improved. Therefore, we propose an opening device for ancient tea tree grafting planting. Utility Model Content

[0007] By adopting the above technical scheme, the left side of the support rod can be made to rest against the right side of the blade, and the rotation angle of the blade can be controlled by adjusting the position of the support rod, thereby controlling the angular position of the blade, and then the fixing frame is put on the outside of the tea tree, and the fixing strip is moved downward to realize the opening operation of the blade in the tea tree, and the opening depth can be further controlled according to the thickness of the grafted seedlings, thereby ensuring the grafting survival efficiency of the tea tree, and at the same time, when the opening is not required, the support rod can be controlled to move to the lower end of the fixing strip, so as to facilitate the rotation of the blade to the top of the support rod, and then the blade can be shielded to avoid scratches during carrying.

[0008] Optionally, the size of the screw rod matches the size of the thread groove, and the screw rod is spirally connected to the thread groove.

[0009] By adopting the above technical solution, it is convenient to adjust the position of the support rod by cooperating with the screw rod and the thread groove.

[0010] Optionally, a plurality of balls are rollingly mounted on the inner side of the fixed frame, and the balls are equidistantly distributed.

[0011] By adopting the above technical solution, the setting of the balls is facilitated, thereby ensuring that the fixing frame slides smoothly on the outside of the trunk.

[0012] Optionally, the front end of the blade is rotatably connected to the rear side of the straight rod via a rotating shaft.

[0013] By adopting the above technical solution, the stability of the blade rotation can be ensured.

[0014] Optionally, the lower end of the blade is movably connected to the lower end of the fixing bar.

[0015] By adopting the above technical solution, the blade can be flexibly rotated below the fixed bar.
