Description

Technical Field

[0001] The invention relates to the technical field of plant grafting, in particular to a grafting knife suitable for the end of a rootstock. Background Art

[0002] Grafting is one of the methods of artificial plant reproduction, which involves grafting the branch or bud of one plant onto the stem or root of another plant so that the two connected parts can grow into a complete plant. Grafting methods are divided into branch grafting and bud grafting. Grafting is carried out by utilizing the plant's ability to heal after being injured.

[0003] Based on the above description, and in combination with the equipment in the prior art, it is found that in the existing grafting, the staff uses a knife to manually cut a grafting port on the rootstock, then puts the scion into the grafting port, applies plant growth liquid to the port, and finally wraps the port with a covering film. However, such an operation will cause the staff to make mistakes and lead to inconsistent incision depths because they cannot always grasp the depth of the incision. Moreover, when the grafting port is opened and the growth liquid is applied, the incision will be torn due to stress, which will cause the failure of the grafting. At the same time, the grafting port cannot be covered with a film in time, which will also cause the grafting port to be infected, reducing the survival rate of the grafting. Therefore, this design aims at the above problems and designs a grafting knife with reasonable structure and good functionality suitable for the end of the rootstock to improve practicality.

[0033] The outer ends of the first cross arm 1 and the second cross arm 2 on the other side are fixedly connected with a wrapping plate 5, the inner side of the wrapping plate 5 is fixedly connected with a spring 501, and the wrapping plate 5 is movably connected with a meniscus 7 through the spring 501, and the outer side of the wrapping plate 5 is rotatably connected with a binding belt roll 6 through a bearing;

[0034] A ladder groove 4 is fixedly connected between the second cross arms 2 on the other side, a pressure-bearing rod 201 is integrated at the lower edge of the second cross arm 2 on the other side, a cutting knife 9 is integrated at the other side of the pressure-bearing rod 201, a truss 8 is embedded on the outside of the cutting knife 9, a slide groove 801 is provided at the middle opening above the truss 8, the other side of the truss 8 is rotatably connected to a positioning rod 802 through a connecting shaft, and the other side of the positioning rod 802 is fixedly connected to the rotating shaft 3, and a water seepage port 901 is penetrated through the surface of the cutting knife 9.

[0035] Among them, the middle part of the second cross arm 2 on the other side is open, and the span of the opening is eight centimeters. The ladder groove 4 is located in the middle of the opening, and a groove is provided on the surface of the ladder groove 4. The groove can be used to place the scion. When the cutting knife 9 cuts the grafting port of the rootstock, the scion can be easily matched with the rootstock incision.

[0036] Among them, the pressure rod 201 extends all the way out of the slide groove 801, and the interior of the truss 8 is hollow, one side of the truss 8 is open, the cutting knife 9 is movably connected to the truss 8, and the cutting knife 9 can move inside the truss 8. As a result, the first cross arm 1 and the second cross arm 2 are subjected to force. When the wrapping plate 5 clamps the stock, the pressure rod 201 will also be subjected to linkage force, so that the pressure rod 201 opens the stock by pushing the cutting knife 9 out from the inside of the truss 8, so that the cutting depth is stable and consistent, and the incision is smooth.

[0037] Among them, the cutting knife 9 and the pressure rod 201 are hollow inside, and the conduit 1022 penetrates the pressure rod 201 and extends to the inside of the cutting knife 9.

[0041] Among them, a connecting shaft is embedded in the connection between the truss 8 and the positioning rod 802, and a torsion spring is nested outside the connecting shaft. The two sides of the torsion spring are respectively subjected to force on the truss 8 and the positioning rod 802. Due to the action of the torsion spring, the truss 8 and the positioning rod 802 can be rotated at a certain angle, so that the pressure rod 201 can better push the cutting knife 9 out, making the use of the entire device smoother.

[0042] The specific usage and function of this embodiment are as follows:

[0043] In the present invention, the functional integrity of the device is firstly ensured, and then the device is placed in the grafting position, and the wrapping plate 5 is put on the end of the rootstock to squeeze the first cross arm 1 and the second cross arm 2. At this time, due to the rotation of the bearing shaft 3, the other side of the first cross arm 1 and the second cross arm 2 shrinks inward, and the meniscus 7 is subjected to stress as the wrapping plate 5 wraps the rootstock, and the meniscus 7 can press the binding belt on the rootstock. At the same time, the pressure rod 201 will also be subjected to linkage stress. A connecting shaft is embedded at the connection between the truss 8 and the positioning rod 802, and a torsion spring is nested outside the connecting shaft, so that the pressure rod 201 opens the rootstock by pushing the cutting knife 9 out from the inside of the truss 8. At this time, the first cross arm 1 and the second cross arm 2 are subjected to stress. The push-type pump 1021 can be pressurized, so that the push-type pump 1021 pumps out the growth liquid inside the water storage chamber 102, introduces it into the inside of the cutting knife 9 through the catheter, and discharges the growth liquid from the seepage port 901. As the cutting knife cuts, the growth liquid is just smeared on the inside of the stock incision, thereby improving the survival rate of the graft. When the incision is completed, the middle part of the second cross arm 2 on the other side is open, and the ladder groove 4 is located in the middle of the opening. The groove on the surface of the ladder groove 4 can be used to place the scion, so that the scion is conveniently matched with the stock incision. Then, the first cross arm 1 and the second cross arm 2 are loosened to rotate the entire device, and the binding belt will also cover the grafted part with a film as the device rotates, thereby improving the cleanliness of the grafted part.
