Description

Technical Field

[0001] This utility model relates to a clamping tool for grafting, belonging to the technical field of grafting tooling. Background Technology

[0002] Grafting is an indispensable step in vegetable production for disease resistance and yield improvement. In current greenhouse cultivation, due to the differences and diversity of plants and vegetables, grafting is mostly done manually. This requires high skill levels from workers, is time-consuming and labor-intensive, and has low efficiency. Existing manual, semi-automatic, and automatic grafting machines are mostly used for single-plant grafting. The process is roughly as follows: the top (branches and leaves, etc.) of the rootstock is cut off with scissors, leaving a slanted cut; the root of the scion is cut off with scissors, leaving a slanted cut; then the cuts of the rootstock and scion are aligned; and clamps are used to hold the rootstock and scion together until the cuts are in contact, completing the single-plant grafting. The grafted plant is then transplanted into potting soil (seedling pot). This method can only perform single-plant positioning and alignment of rootstock and scion at a time, making it difficult to achieve batch grafting of multiple plants for high efficiency. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, this utility model provides a clamping tool for grafting, and the specific technical solution is as follows.

[0004] A clamping fixture for grafting, characterized in that it includes a frame structure, a first clamp for clamping the rootstock, and a second clamp for clamping the scion;

[0005] Two or more first clamps are arranged side by side, and two or more second clamps are arranged side by side, with each first clamp and each second clamp corresponding to the other.

[0006] The first clamp includes a fixing part and an elastic pressure strip disposed on the frame structure, and the second clamp also includes a fixing part and an elastic pressure strip disposed on the frame structure. This technical solution facilitates the simultaneous clamping of multiple rootstocks and scions using clamping fixtures, ensuring a one-to-one correspondence between each rootstock and each scion, thus facilitating subsequent grafting operations. The fixing part and the elastic pressure strip form an openable clamp. After opening the elastic pressure strip, the rootstock (or scion) is placed at the fixing part, and then the elastic pressure strip is released. Under its own elastic force, the elastic pressure strip presses the rootstock (or scion) against the fixing part, thereby achieving clamping and positioning of the rootstock (or scion).

[0007] Furthermore, the first clamp is located below the second clamp; the frame structure is also provided with a support plate, which is located below the first clamp. The support plate can be used to support the rootstock seedling pot, so that the rootstock and scion can be roughly vertical when clamped, and grafting operations can be carried out with the seedling pot attached, thus solving the problem of large-scale production of grafted plants and vegetables. First, the precise clamping and positioning of each group of rootstock and scion meets the positioning problem of post-grafting process, and the subsequent cutting and clamping of the grafted seedling can be completed quickly. Related processes are reduced, firstly, the cutting and repositioning are done after the cutting. Secondly, at least two rootstock transplanting operations can be reduced (in the prior art, before the grafting operation, the rootstock needs to be removed from the seedling pot for cutting, clamping, etc., and after the grafting operation, it needs to be transplanted back into the seedling pot), which greatly improves the efficiency of grafting operation and reduces labor intensity; moreover, in the process of realizing mechanized operation, the clamping fixture can be kept clean and hygienic, and soil should not be spilled into the clamping fixture. Furthermore, ensuring the integrity of the substrate soil for seedling cultivation is beneficial to the later growth and survival rate of grafted seedlings. Preferably, the height of the support plate is adjustable. For example, the support plate can be fixed at different heights of the grafting fixture with fasteners, or pads of different heights can be set under the support plate. In short, those skilled in the art will know that the height of the support plate can be adjusted by conventional means. This allows the clamping fixture to adapt to different types of rootstocks, and the height of the support plate can be adjusted according to the height of the specific rootstock.

[0008] Furthermore, the elastic pressure strips of several first fixtures are all disposed on mounting bases, which are fixed to the frame structure by fasteners. Similarly, the elastic pressure strips of several second fixtures are all disposed on mounting bases, which are fixed to the frame structure by fasteners. This approach reduces the manufacturing difficulty of the tooling, allowing the elastic pressure strips and mounting bases to be manufactured independently of the frame structure, and then the mounting bases are fixed to the mounting frame to complete the assembly. Moreover, it facilitates replacement when the elastic pressure strips are damaged.

[0009] Furthermore, it also includes a slot structure disposed on the frame structure, the slot structure being located below the first clamp. The slot structure is used to accommodate and position the seedling pot of the rootstock, preventing the seedling pot from moving on the support plate. Preferably, the slot structure is connected to the support plate, and the slot structure and the support plate together form a bracket structure, the bracket structure having a vertically extending strip-shaped hole; the bracket structure is fixed to the frame structure by fasteners.

[0010] Furthermore, it also includes an auxiliary unloading device, which includes a base with a bottom support, side positioning blocks, and seedling unloading protrusions. The bottom support supports the lower surface of the frame structure. Two side positioning blocks are provided, each for positioning the two side surfaces of the frame structure. Multiple seedling unloading protrusions are provided, with each elastic pressure strip of the first and second clamps corresponding to one seedling unloading protrusion. When the clamping fixture is positioned between two side positioning blocks and moves towards the seedling unloading protrusion, the seedling unloading protrusion can push open the elastic pressure strip. By providing the auxiliary unloading device, all the first and second clamps on the clamping fixture can be opened at once, thus facilitating efficient seedling unloading operations.

[0011] Compared with the prior art, this invention can gently clamp multiple rootstocks and scions at once, enabling simultaneous grafting of multiple seedlings, thus significantly improving grafting efficiency. It is also simple and easy to operate. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] See Figures 1-7 A clamping fixture for grafting includes a frame structure 1, a first clamp 2 for clamping the rootstock 4, and a second clamp 3 for clamping the scion 5. The frame structure 1 is a structural foundation that provides support, and its shape is not specifically limited, as long as it can meet the installation and use of other components.

[0026] Two or more first clamps 2 are arranged side by side, and two or more second clamps 3 are arranged side by side, with the first clamps 2 and the second clamps 3 being arranged in a one-to-one correspondence;

[0027] The first clamp 2 includes a fixing part 6 and an elastic pressing strip 7, and the second clamp 3 also includes a fixing part 6 and an elastic pressing strip 7. This technical solution facilitates the simultaneous clamping of multiple rootstocks 4 and multiple scions 5 using clamping fixtures, ensuring a one-to-one correspondence between each rootstock 4 and each scion 5, thus facilitating subsequent grafting operations. The fixing part 6 and the elastic pressing strip 7 form an openable clamp. After opening the elastic pressing strip 7, the rootstock 4 (or scion 5) is placed at the fixing part 6. Then, the elastic pressing strip 7 is released, and under its own elastic force, it presses the rootstock 4 (or scion 5) against the fixing part 6, thereby achieving clamping and positioning of the rootstock 4 (or scion 5). The operation is very simple. The fixing part 6 can have a T-shaped cross-section, facilitating the placement of the rootstock and scion. The elasticity of the elastic pressing strip 7 is moderate, ensuring reliable clamping of the rootstock and scion without damaging them. The elastic pressure strip 7 has protrusions 7.1 that are easy for operators to pry open by hand.

[0028] The first clamp 2 is located below the second clamp 3; the frame structure 1 is also provided with a support plate 8, which is located below the first clamp 2. The support plate 8 can be used to support the seedling pot 9 of the rootstock 4, so that the rootstock 4 and scion 5 can be roughly vertical when clamped, and the grafting operation can be carried out with the seedling pot 9 attached. This can reduce the transplanting operation of the rootstock 4 by at least two times (in the prior art, before the grafting operation, the rootstock 4 needs to be removed from the seedling pot 9 for cutting, clamping, etc., and after the grafting operation, it needs to be transplanted back into the seedling pot 9), which greatly improves the efficiency of the grafting operation and reduces the labor intensity; moreover, the clamping tool can be kept clean and hygienic during the mechanized operation, avoiding soil spillage in the clamping tool. It also ensures the integrity of the substrate soil for cultivating seedlings, which is conducive to the growth and survival rate of grafted seedlings in the later stage. Preferably, the height of the support plate 8 is adjustable. For example, the support plate 8 can be fixed at different heights of the grafting fixture by fasteners, or pads of different heights can be provided below the support plate 8. In short, those skilled in the art will know that the height of the support plate 8 can be adjusted by conventional means. This allows the clamping fixture to adapt to different types of rootstock 4, and the height of the support plate 8 can be adjusted according to the height of the specific rootstock 4.

[0029] Preferably, such as Figure 3 , Figure 4 As shown, several elastic pressure strips 7 of the first clamps 2 are all disposed on the mounting base 10, and the mounting base 10 is fixed to the frame structure 1 by fasteners (screws, etc.). Several elastic pressure strips 7 of the second clamps 3 are also disposed on the mounting base 10, and the mounting base 10 is fixed to the frame structure 1 by fasteners. This method helps reduce the manufacturing difficulty of the tooling, as the elastic pressure strips 7 and mounting bases 10 can be manufactured independently of the frame structure 1, and then the mounting base 10 is fixed to the mounting frame to complete the assembly work; moreover, it is convenient to replace the elastic pressure strips 7 when they are damaged. Preferably, the elastic pressure strips 7 and mounting bases 10 are integrally formed structures for easy replacement. Of course, the elastic pressure strips 7 and mounting bases 10 can also be configured to include several standard modules, and some modules can be replaced individually when damaged.

[0030] Preferably, such as Figure 7As shown, it also includes a slot structure 11 disposed on the frame structure 1, located below the first clamp 2. The slot structure 11 is used to accommodate and position the seedling pot 9 of the rootstock 4, preventing the seedling pot 9 from moving on the support plate 8. Preferably, the slot structure 11 is connected to the support plate 8, and the slot structure 11 and the support plate 8 together form a bracket structure. The bracket structure has a vertically extending strip hole 12. The bracket structure is fixed to the frame structure 1 by fasteners (screws, etc.). The height of the bracket structure can be adjusted through the strip hole 12. After the height is adjusted, the bracket structure is fixed to the frame structure 1 using fasteners. The bracket structure can be integrally molded, which is beneficial for reducing installation steps. Of course, the bracket structure can also be several standard modules, and some modules can be replaced individually if damaged.

[0031] Preferably, such as Figures 8-11 As shown, it also includes an auxiliary unloading device 13, which includes a base 13.1. The base 13.1 is provided with a bottom support 13.2, side positioning blocks 13.3, and seedling unloading protrusions 13.4. The bottom support 13.2 is used to support the lower surface of the frame structure 1. There are two side positioning blocks 13.3, which are used to position the two side surfaces of the frame structure 1 respectively. There are multiple seedling unloading protrusions 13.4. Each elastic pressure strip 7 of the first clamp 2 and the second clamp 3 is provided with a corresponding seedling unloading protrusion 13.4. When the clamping fixture is positioned between two side positioning blocks 13.3 and moves toward the seedling unloading protrusion 13.4, the seedling unloading protrusion 13.4 can push open the elastic pressure strip 7. By setting the auxiliary unloading device 13, all the first clamps 2 and the second clamps 3 on the clamping fixture can be opened at once, which is conducive to efficient seedling unloading operation. Preferably, the seedling unloading protrusion 13.4 has a chamfered surface facing the elastic pressure strip 7. Opening the elastic strip 7 by chamfering the surface helps protect the elastic strip 7 and improve its service life.
