Description

Technical Field

[0001] The utility model relates to the field of plant grafting, in particular to an auxiliary device for fruit tree grafting. Background Art

[0002] Fruit tree grafting is to combine a part of two different fruit tree plants together so that they share the same root system, thereby achieving the purpose of utilizing the advantages of the two fruit trees and improving the growth, yield, and tolerance of the fruit trees. Usually, fruit tree grafting is to graft the required fruit tree variety (called scion) onto another fruit tree with stronger rootstock (called rootstock), because the rootstock can provide better root system and stress resistance, while the scion determines the quality and characteristics of the fruit.

[0003] The grafting auxiliary device usually includes a gripper or fixator, which can help ensure that the scion and rootstock are correctly and firmly combined together, and is used to maintain the stable state of the scion and rootstock during grafting, thereby increasing the success rate of grafting. The fruit tree grafting auxiliary device plays an important role in modern fruit tree planting industry, not only improving the success rate and efficiency of grafting, but also ensuring the health and productivity of fruit trees, and promoting the improvement of fruit tree varieties and the increase of yield.

[0004] The structure of the traditional grafting auxiliary device is single and inconvenient to operate, and does not consider that different types of fruit trees may require grafting auxiliary devices of different sizes. Therefore, the existing devices are not applicable to all fruit tree species, which limits their application scope in diversified fruit tree planting. For this reason, an auxiliary device for fruit tree grafting is proposed to solve the above problems. Summary of the Invention

[0005] The utility model is to solve the above technical problems, and provides an auxiliary device for fruit tree grafting, aiming to solve the technical problem that the grafting position cannot be adjusted to adapt to the grafting of tree branches of different lengths in the prior art.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An auxiliary device for fruit tree grafting, which includes a semi-circular plate and an auxiliary plate. Pressure plates are arranged inside the semi-circular plate and the auxiliary plate. Spring I is fixedly connected between the semi-circular plate and the pressure plate, and between the auxiliary plate and the pressure plate. Card slots I are opened inside the semi-circular plate and the auxiliary plate. Sub-buckles are arranged inside the semi-circular plate and the auxiliary plate. The side wall of the sub-buckle is fixedly connected inside the card slot I. Card slots II are opened inside the semi-circular plate and the auxiliary plate. Fixed tubes are arranged inside the semi-circular plate and the auxiliary plate. Female buckles are arranged inside the fixed tubes. Spring II is fixedly connected between the fixed tube and the female buckle. The side wall of the sub-buckle is slidably connected between the female buckles.

[0008] As a further description of the above technical solution: A protective cover is fixedly connected to the side wall of the semi-circular plate. A rotating column is rotatably connected inside the protective cover. A gear is fixedly connected to the side wall of the rotating column. A first rack is arranged inside the protective cover. A first fixing block is fixedly connected to one side of the first rack, and a first limiting block is fixedly connected to the other side of the first rack.

[0009] As a further description of the above technical solution: A second rack is arranged inside the protective cover. A second limiting block is arranged on one side of the second rack, and a second fixing block is fixedly connected to the other side of the second rack.

[0010] As a further description of the above technical solution: The side wall of the first fixing block is fixedly connected to the side wall of the top auxiliary plate, and the side wall of the second fixing block is fixedly connected to the side wall of the bottom auxiliary plate.

[0011] As a further description of the above technical solution: The first rack meshes with the gear, and the second rack meshes with the gear.

[0012] As a further description of the above technical solution: The opposite sides of the semi-circular plate are set as arc angles, and the opposite sides of the auxiliary plate are set as arc angles.

[0013] As a further description of the above technical solution: The semi-circular plate is arranged between two auxiliary plates; the semi-circular plate and the auxiliary plates are connected by the first rack and the second rack.

[0014] Due to the adoption of the above technical solution, the present utility model has the following beneficial effects:

[0015] In the grafting part of the present utility model, the male buckle and the female buckle are engaged with each other by pressure, so that the two semi-circular plates are closed. At this time, the pressure plates inside the two semi-circular plates will squeeze the transplanted branches for fixation. Because the first spring has elasticity, the pressure plates can squeeze and fix branches with different shapes and different thicknesses. The auxiliary plates can fix the branches outside the transplanted part for further fixation, solving the problem that the simple fixing plates of the grafting auxiliary device are not firmly fixed, which affects the grafting effect. The device is convenient for fixing the grafted branches, thus achieving a more stable effect and improving the survival rate of trees. The two middle semi-circular plates are closed. Because both the first rack and the second rack mesh with the gear, when the fixed length needs to be adjusted, only the auxiliary plate needs to be pulled. At this time, the two end auxiliary plates will extend outwards, solving the problem of the single structure of the traditional tree branch grafting, achieving the effects of grafting with different lengths adjustable and adjusting the fixed length, making the device applicable and improving the flexibility of the auxiliary equipment.

Specific implementation mode

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments, and the protection scope of the present utility model is not limited by the embodiments.

[0025] As Figures 1-5 shown, an auxiliary device for fruit tree grafting of the present utility model includes a semi-circular plate 1 and an auxiliary plate 2. Pressure plates 3 are arranged inside both the semi-circular plate 1 and the auxiliary plate 2. First springs 4 are fixedly connected between the semi-circular plate 1 and the pressure plate 3 and between the auxiliary plate 2 and the pressure plate 3. First card slots 5 are opened inside both the semi-circular plate 1 and the auxiliary plate 2. Sub-buttons 6 are arranged inside both the semi-circular plate 1 and the auxiliary plate 2. The side walls of the sub-buttons 6 are fixedly connected inside the first card slots 5. Second card slots 7 are opened inside both the semi-circular plate 1 and the auxiliary plate 2. Fixed tubes 8 are arranged inside both the semi-circular plate 1 and the auxiliary plate 2. Mother buttons 10 are arranged inside the fixed tubes 8. Second springs 9 are fixedly connected between the fixed tubes 8 and the mother buttons 10. The side walls of the sub-buttons 6 are slidably connected between the mother buttons 10.

[0026] During the operation of the device, when the grafting part is inside the semi-circular plate 1, pressure can be applied to make the sub-button 6 slide along the rear of the mother button 10. When the sub-button 6 passes by the mother button 10, the second spring 9 contracts under the influence of the external pressure. When the sub-button 6 reaches the rear position of the mother button 10, the second spring 9 returns to its original position as the pressure is released. At this time, the sub-button 6 engages with the mother button 10, enabling the two middle semi-circular plates 1 to close. After the closing action is completed, under the pressure of the first spring 4, the pressure plate 3 is pushed to squeeze the branches at the grafting position to achieve a fixing effect. Since the first spring 4 has good elastic properties, the pressure plate 3 can squeeze and fix flexibly according to the different thicknesses of the branches, ensuring the stability of the grafting process and the survival rate after grafting. This reflects the efficiency and convenience of the device design in practical applications.

[0027] As Figure 6 shown, a protective cover 11 is fixedly connected to the side wall of the semi-circular plate 1. A rotating column 12 is rotatably connected inside the protective cover 11. A gear 13 is fixedly connected to the side wall of the rotating column 12. A first rack 14 is arranged inside the protective cover 11. A first fixing block 15 is fixedly connected to one side of the first rack 14. A first limiting block 16 is fixedly connected to the other side of the first rack 14. A second rack 17 is arranged inside the protective cover 11. A second limiting block 18 is arranged on one side of the second rack 17. A second fixing block 19 is fixedly connected to the other side of the second rack 17. The side wall of the first fixing block 15 is fixedly connected to the side wall of the top auxiliary plate 2. The side wall of the second fixing block 19 is fixedly connected to the side wall of the bottom auxiliary plate 2. The first rack 14 meshes with the gear 13. The second rack 17 meshes with the gear 13. The opposite sides of the semi-circular plate 1 are set as arc angles. The opposite sides of the auxiliary plates 2 are set as arc angles. The semi-circular plate 1 is arranged between the two auxiliary plates 2. The semi-circular plate 1 and the auxiliary plates 2 are connected by the first rack 14 and the second rack 17.

[0028] During the grafting process, first, the two middle semi-circular plates 1 are fixed at the grafting position. Next, the positions of the upper and lower auxiliary plates 2 are adjusted. Through the meshing action between the first rack 14 and the gear 13, as the auxiliary plate 2 slides, the first fixing block 15 will also slide accordingly. The first fixing block 15 drives the first rack 14 to move correspondingly. Since there is also a meshing action between the second rack 17 and the gear 13, when the first rack 14 drives the gear 13 to rotate, the second rack 17 will also move under the influence of the meshing action. After adjusting to the ideal length, pressure is applied again to make the sub-button 6 engage with the mother button 10, and the upper and lower auxiliary plates 2 close, thereby achieving effective fixation of the fruit tree grafting position.

[0029] The working principle of the utility model is as follows: When using this device, when the grafting part is inside the semi-circular plate 1, by extrusion, the sub-button 6 moves towards the rear side of the mother button 10. When the sub-button 6 passes through the mother button 10, the second spring 9 contracts due to the external pressure. When the sub-button 6 reaches the rear side of the mother button 10, the second spring 9 loses pressure and resets. At this time, the sub-button 6 is engaged with the mother button 10, causing the two middle semi-circular plates 1 to close. At this time, under the pressure of the first spring 4, the pressure plate 3 squeezes the branches at the grafting part for fixation. Because the first spring 4 is elastic, the pressure plate 3 can squeeze and fix branches of different thicknesses. After the two middle semi-circular plates 1 are fixed at the grafting part, then adjust the upper and lower auxiliary plates 2. Under the meshing action of the first rack 14 and the gear 13, pull the auxiliary plate 2, and the auxiliary plate 2 will drive the first fixing block 15 to slide, and the first fixing block 15 will drive the first rack 14 to move. Because the second rack 17 is meshed with the gear 13, so when the first rack 14 drives the gear 13 to rotate, the second rack 17 also moves under the meshing action. When adjusted to the required length, squeeze again to make the sub-button 6 engaged with the mother button 10, causing the upper and lower auxiliary plates 2 to close, thus completing the fixation of the grafting part of the fruit tree.
