Description

Technical Field

[0001] The utility model relates to the technical field related to grafting tools, in particular to a pear tree grafting auxiliary device. Background Art

[0002] Grafting is a method of reproduction in which a bud or branch of a plant is grafted onto another plant so that the two parts grow into a complete plant. The grafted bud or branch is called a scion, and the grafted plant is called a rootstock. The key to a successful graft is to tightly combine the cambium of the scion and the rootstock. Grafting is carried out by utilizing the healing function of plants after being injured. There are two main methods of grafting pear trees: bud grafting and branch grafting. Among them, branch grafting is more suitable for use when pear trees sprout in spring, while bud grafting is more suitable for use when the branches, leaves, and axils of the pear tree are relatively full.

[0003] In order to improve the survival rate of grafting, the wound must be wrapped after the grafting is completed. First, it is to prevent rainwater from entering and resist wind and splitting. Secondly, it will protect the dispersion of small water droplets. Existing pear trees are usually wrapped with transparent plastic film after grafting. Generally, the manual method is adopted to clamp and fix the scion and rootstock with a grafting clamp, and then wrap the work. When there are a large number of grafted pear trees, this method will reduce the efficiency of grafting and has low practicality. Utility Model Content

The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0025] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0026] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0027] See also Figure 1 to Figure 6 In an embodiment of the utility model, a pear tree grafting auxiliary device includes a mounting frame 1, an elastic fabric 4, a clamping member, and an elastic extrusion member.

[0028] For details, please refer to Figure 1 , Figure 2 , Figure 3 ,include;

[0029] A mounting frame 1 and a clamping member symmetrically arranged on the mounting frame 1, wherein the clamping member can rotate relative to the mounting frame 1,

[0030] It also includes an elastic extrusion member, one end of which is rotatably connected to the mounting frame 1, and the other end of which is rotatably connected to the clamping member. When the clamping member is controlled to rotate relative to the mounting frame 1, the elastic extrusion member is deformed to clamp onto the grafted branch.

[0031] The two ends of the elastic cloth 4 are rotatably connected to the clamping member respectively. When the clamping member clamps the grafted branch, the elastic cloth 4 wraps the grafted wound.

[0032] In detail, in this embodiment, the pear tree grafting auxiliary device described in the utility model is adopted. When in use, the clamping member is rotated relative to the mounting frame 1 by manually controlling the rotation thereof. The rotation angle of the clamping member is adjusted according to the thickness of different pear branches. When the clamping member is deflected, the elastic extrusion property is deformed. When the driving of the clamping member to rotate is stopped, the scion and stock of different thicknesses can be clamped under the action of the elastic potential energy stored in the elastic extrusion member. The elastic cloth 4 adapts to the pear branches of different thicknesses and quickly wraps the grafting wound. While stabilizing the tightness of the combination of the scion and the stock, it is convenient for the clamping member and the elastic cloth 4 to be quickly disassembled and installed.

[0033] When the above-mentioned clamping parts clamp the scion and the rootstock, the elastic cloth 4 is deformed to quickly wrap the grafting wound, and under the action of its own elasticity, it can wrap the grafting wound of different thicknesses. Among them, the elastic cloth 4 is made of transparent material, and its main purpose is to increase the air humidity and prevent the scion from losing water.

[0034] Preferably, the mounting frame 1 is symmetrically formed with at least one group of strip grooves 101 , and a sleeve 3 is slidably disposed in the strip groove 101 .

[0035] It should be noted that at least one set of limiting grooves 102 is formed in the strip groove 101, and a limiting block 301 is formed on the sleeve 3 to slide with the limiting groove 102. Under the limiting action of the limiting groove 102 and the limiting block 301, the sliding connection between the sleeve 3 and the mounting frame 1 is achieved.

[0036] See also Figure 5 A rotating shaft 2 is arranged along the axial direction of the sleeve 3, and the rotating shaft 2 is fixedly connected to the sleeve 3. As shown in the figure, the rotating shaft 2 includes an upper rotating shaft and a lower rotating shaft.

[0037] See also Figure 1 The clamping member includes symmetrically arranged clamping jaws 5, and the clamping jaws 5 are arranged in a V-shaped structure. One end of the clamping jaw 5 is rotatably connected to the rotating shaft 2, and a plurality of locking teeth 501 are equidistantly arranged on the other end.

[0038] Furthermore, the clamping jaws 5 are controlled to rotate relative to the mounting frame 1 so that the angle between the two clamping jaws 5 changes. The distance between the two clamping jaws 5 is adjusted according to the thickness of the clamped pear branch. For branches with relatively larger or smaller thicknesses, the sleeve 3 is controlled to move relative to the mounting frame 1. When the sleeve 3 moves, the clamping jaws 5 are driven to move synchronously, thereby adjusting the distance between the two clamping jaws 5 to achieve the clamping of pear branches of different thicknesses. When the clamping jaws 5 clamp the pear branch, the latch teeth 501 thereon increase the friction between the clamping jaws 5 and the pear branch, thereby preventing the clamping jaws 5 from shaking and falling off the pear branch.

[0039] Preferably, a connecting shaft 6 is fixedly connected between the two clamping jaws 5 to achieve synchronous movement of the two clamping jaws 5 on the same side.

[0040] See also Figure 3 and Figure 4 The elastic extrusion member includes a connecting tube 7 and a connecting rod 8, one end of the connecting tube 7 is rotatably connected to the connecting shaft 6, and the connecting rod 8 is slidably arranged in the other end, and the end of the connecting rod 8 away from the connecting tube 7 is rotatably connected to the rotating shaft 2;

[0041] It also includes a spring 9 , which is disposed in the connecting tube 7 , one end of the spring 9 abuts against the inner bottom of the connecting tube 7 , and the other end of the spring 9 abuts against the connecting rod 8 .

[0042] In detail, when the above-mentioned clamping jaw 5 is deflected, it drives the connecting tube 7 and the connecting rod 8 to rotate synchronously. When the clamping jaw 5 is deflected, the spring 9 is compressed with the lower rotating shaft as the center of the circle to store elastic potential energy. When the driving of the clamping jaw 5 to deflect stops, under the elastic action of the spring 9, the clamping jaw 5 is driven to rotate quickly and clamp the pear branch. When the clamping jaw 5 clamps the pear branch, the spring 9 is in a compressed state to achieve the clamping work requirements of the clamping jaw 5.
