Description

Technical Field

[0001] The present invention relates to the technical field of seedling grafting, in particular to a high-efficiency seedling grafting device and a use method thereof. Background Art

[0002] Grafting is a horticultural technique used to join tissue from one plant (called the scion) to another (called the rootstock), allowing the two to heal and continue growing as a single unit. This method can be used to improve plant growth characteristics, such as disease resistance and cold tolerance, or to alter fruit quality. Traditional grafting typically requires multiple manual steps, including cutting the scion and rootstock, preparing the incision, and aligning and securing the scion and rootstock. Cutting the scion and rootstock is the most challenging step, as the angle and depth of the incision have a direct impact on the graft's survival rate.

[0003] Manual cutting can easily lead to uneven cuts, which will directly affect the contact area between the scion and the rootstock. The angle and depth of the cut will directly affect the fit between the rootstock and the scion, thereby affecting the success rate of the grafting. In addition, fingers may be cut accidentally during the cutting process. Severe cuts may cause temporary or permanent loss of some functions of the fingers. In traditional methods, healing agents are usually applied manually with a brush, which is inefficient. Therefore, an efficient seedling grafting device and its use method are needed to solve the above problems. Summary of the Invention

[0014] A method for using an efficient seedling grafting device comprises the following steps: Step 1: Cut the scion. Place the scion between the first clamp head and the second clamp head to ensure that the scion is in the correct position. Hold the first clamp rod and the second clamp rod with your hands to clamp the scion with the first clamp head and the second clamp head. Continue to use force to rotate the second clamp rod to drive the V-shaped cutter to cut the scion, so that a V-shaped protruding incision is formed at the lower end of the scion. After the cutting is completed, due to the presence of the elastic ball and the spherical groove, the first clamp head and the second clamp head will continue to maintain the clamping force on the scion to ensure the stability of the scion. Step 2: Spray the incision. After the scion is cut, press the third clamp rod upwards and use the lever principle to squeeze the nozzle of the spray bottle, so that the plant healing agent is sprayed onto the incision of the scion through the spray bottle, which helps to keep the incision moist and promote healing. After spraying, remove the scion; Step 3: Cut the stock. Place the stock between the first baffle and the second baffle so that the top of the stock is flush with the bottom of the elastic frame. Repeat the operation in step 1, clamp the stock and cut. The cut portion of the upper end of the stock is pushed down by the ejection block, so that a V-shaped groove is formed on the top of the stock to match the scion. The V-shaped cutter passes through the guide groove of the second guard plate to cut. The scraper in the guide groove can help remove stains on the cutter. Step 4: spray the incision. After the stock is cut, repeat the operation in step 2 to spray the incision of the stock with the healing agent. Step 5: Grafting: Insert the V-shaped protrusion at the bottom of the scion into the V-shaped groove at the top of the rootstock, so that the scion and the rootstock are in close contact, and then wrap them with the grafting film.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention integrates the functions of fixing, cutting and spraying, simplifies the grafting process, and improves work efficiency. The V-shaped cutter design can quickly form a V-shaped incision. This incision form can increase the contact area between the scion and the rootstock, which is conducive to the close combination of the cambium layer. The cutting is performed after clamping to avoid cutting fingers during cutting. The incision angles on the scion and the rootstock are the same, which improves the fit between the scion and the rootstock, thereby improving the success rate of grafting.

[0016] 2. The present invention has a built-in spray component that sprays the plant healing agent immediately after cutting. It can quickly spray the plant healing agent on the incision, which helps to keep the incision moist and promote healing, thereby improving the graft survival rate. The spray pot and the positioning frame adopt an interference fit connection, which is convenient for quick disassembly and replenishment of the agent, and is convenient for daily maintenance and cleaning. The finger-dial operation mode allows the user to complete the cutting and spraying functions with one hand, and the other hand can be used to take the cut scion for subsequent grafting, thereby improving the convenience of the grafting operation.

[0017] 3. The present invention can promptly scrape off the stains on the V-shaped cutter by arranging a scraper in the guide groove, thereby reducing rust and oxidation of the cutter and extending its service life. At the same time, it can prevent sap from adhering to the cutter, causing bacteria to grow on the cutter surface and affecting the graft survival rate. The guide groove limits the movement trajectory of the V-shaped cutter, ensuring the correct cutting direction, reducing deviation, and improving the smoothness of the incision.

The positioning frame 303 is fixedly mounted on the lower end of the connecting shaft 105 . The spray pot 302 is detachably mounted on the positioning frame 303 .

[0021] Furthermore, a first rotating shaft 1041 and a torsion spring 1042 are provided at the front end of the second clamp rod 102, and the second clamp head 104 is rotatably connected to the second clamp rod 102 through the first rotating shaft 1041 and the torsion spring 1042. A limiting column 1023 is provided on the upper end surface of the second clamp rod 102, and a limiting rod 1043 is provided on the second clamp head 104 to cooperate with the limiting column 1023.

[0022] The elastically rotatably connected second clamp rod 102 structure enables the second clamp rod 102 to continue to rotate and feed after the second clamp head 104 and the first clamp head 103 clamp the scion, thereby driving the V-shaped cutter 201 to cut the scion, and during the resetting process, after the V-shaped cutter 201 is reset, the first clamp head 103 and the second clamp head 104 still have a certain clamping force on the scion, which can stably clamp the scion.

[0023] Furthermore, an elastic frame 1031 is provided on the inner end surfaces of the first clamp head 103 and the second clamp head 104 . The elastic frame 1031 is a circular arc strip hollow structure. A rubber pad 1032 is provided on the outer side of the elastic frame 1031 .

[0024] The hollow elastic frame 1031 structure has good elasticity. The elastic frame 1031 improves the fit between the first clamp head 103 and the second clamp head 104 and the scion to prevent the scion from loosening and falling. The rubber pad 1032 structure can effectively prevent the first clamp head 103 and the second clamp head 104 from clamping the scion.

[0025] Furthermore, a first guard plate 1034 is provided at the bottom of the first pliers 103, a second guard plate 1048 is provided at the bottom of the second pliers 104, a guide groove 1044 corresponding to the shape of the V-shaped cutter 201 is provided on the second guard plate 1048, the V-shaped cutter 201 passes through the guide groove 1044 and is slidably connected to the second guard plate 1048, a reinforcing rib 2011 is provided on the side of the V-shaped cutter 201, a second rotating shaft 2012 is provided at the lower end of the reinforcing rib 2011, a shaft sleeve 2021 is provided at the front end of the pressure rod 202, and the V-shaped cutter 201 and the pressure rod 202 are rotatably connected through the shaft sleeve 2021 and the second rotating shaft 2012.

[0026] The guide groove 1044 limits the feeding direction of the V-shaped cutter 201, so that the V-shaped cutter 201 always cuts perpendicularly to the stem of the scion, improves the smoothness of the incision, and reduces the cutting resistance. The rotating connected cutter and pressure rod 202 structure can effectively avoid motion interference, and the reinforcing rib 2011 structure enhances the structural strength of the V-shaped cutter 201 to prevent it from deformation.

[0027] Furthermore, a scraper 1046 is provided on the inner end surface of the guide groove 1044 , and a rubber column 1047 is provided between the scraper 1046 and the second guard plate 1048 .

[0028] The scraper 1046 is used to scrape off the stains on the surface of the V-shaped cutter 201, thereby reducing the resin and stains on the surface of the V-shaped cutter 201, reducing the probability of rust and oxidation of the cutter, and improving the service life of the cutter. The elastic rubber column 1047 structure enables the scraper 1046 to exert a certain pressure on the V-shaped cutter 201, so that the scraper 1046 can also fully clean the edge of the V-shaped cutter 201.

[0029] Furthermore, a discharge port 1035 is provided on the side of the first guard plate 1034, and an ejection block 2013 is provided on the side of the reinforcing rib 2011. A second spring 2014 and a bellows 2015 sleeve are provided between the ejection block 2013 and the reinforcing rib 2011. The ejection block 2013 and the reinforcing rib 2011 are elastically connected through the second spring 2014, and a through hole 1045 corresponding to the ejection block 2013 is provided on the second guard plate 1048.

[0030] When the device cuts the stock, the ejector block 2013, under the action of the second spring 2014, squeezes the cut portion of the stock toward the discharge port 1035, thereby pushing the cut waste down and exposing the cut of the stock, making it convenient to spray the plant healing agent.

[0031] Furthermore, the connecting shaft 105 includes a first optical axis portion 1051, a second optical axis portion 1052 and a threaded portion 1053. The axes of the first optical axis portion 1051 and the second optical axis portion 1052 are perpendicular. The threaded portion 1053 is located at the lower end of the first optical axis portion 1051, and the threaded portion 1053 coincides with the axis of the first optical axis portion 1051. The first clamp rod 101 and the second clamp rod 102 are cross-sheathed on the first optical axis portion 1051 and rotatably connected to the connecting shaft 105. The third clamp rod 301 is sheathed on the second optical axis portion 1052 and rotatably connected to the connecting shaft 105. The positioning frame 303 is fixedly installed on the threaded portion 1053 by a nut, and the end of the third clamp rod 301 is in sliding contact with the top of the spray pot 302.

[0032] By pressing the third clamp rod 301 upward, the third clamp rod 301 presses down the spray bottle 302 under the action of the lever, and the plant healing agent is sprayed to the bottom of the scion and the top incision of the stock through the spray bottle 302 to keep the incision moist, while promoting the healing of the stock and scion after grafting, and improving the survival probability of the graft.

[0033] Furthermore, a positioning groove 3031 is provided on the upper end surface of the positioning frame 303 , and the spray pot 302 is inserted into the positioning groove 3031 and is interference-connected therewith.

[0034] The interference-connected spray pot 302 structure is convenient and quick to remove for replenishing reagents or cleaning, thereby further improving the efficiency of seedling grafting.

[0035] Furthermore, a compression spring 106 is provided between the first clamp rod 101 and the second clamp rod 102, and the first clamp rod 101 and the second clamp rod 102 are elastically connected through the compression spring 106. A spherical groove 1011 is provided on the upper end surface of the first clamp rod 101, and a ball 1021 corresponding to the spherical groove 1011 is provided on the lower end surface of the second clamp rod 102. The ball 1021 and the second clamp rod 102 are elastically slidably connected through an elastic spring sheet 1022.

[0036] The elastically connected first clamp rod 101 and second clamp rod 102 can automatically reset after cutting the stock and scion. Through the cooperation of the spherical groove 1011 and the ball 1021, after the first clamp rod 101 and the second clamp rod 102 are separated to a certain angle, the ball 1021 falls into the spherical groove 1011, and there is a pause, which resets the V-shaped cutter 201. However, the first clamp head 103 and the second clamp head 104 remain in contact, making it convenient to spray the healing agent on the incision made when the stock is cut. Example 2 See also Figures 1-10 A method for using an efficient seedling grafting device comprises the following steps: Step 1, scion cutting, select a healthy scion branch, put the scion between the first clamp head 103 and the second clamp head 104, ensure that the scion is in the correct position, hold the first clamp rod 101 and the second clamp rod 102 with your hands, so that the first clamp head 103 and the second clamp head 104 clamp the scion, continue to use force to make the second clamp rod 102 continue to rotate, drive the V-shaped cutter 201 to cut the scion, so that the lower end of the scion forms a V-shaped protruding incision, when the cutting is completed, due to the presence of the elastic ball 1021 and the spherical groove 1011, there will be a certain pause after the ball 1021 is stuck in the spherical groove 1011, at this time, the first clamp head 103 and the second clamp head 104 will continue to maintain the clamping force on the scion to ensure that the scion is stable; Step 2: Spray the incision to ensure that there is enough plant healing agent in the spray pot 302. After the scion is cut, press the third clamp rod 301 upwards to squeeze the nozzle of the spray pot 302 using the lever principle, so that the plant healing agent is sprayed onto the incision of the scion through the spray pot 302, which helps to keep the incision moist and promote healing. After the spraying is completed, gently remove the scion for later use; Step 3, stock cutting, select a suitable stock, the diameter of the stock is equal to or slightly larger than the diameter of the scion, place the stock between the first baffle and the second baffle, make the top of the stock flush with the bottom of the elastic frame 1031, repeat the operation in step 1, clamp the stock and cut, the cut portion of the upper end of the stock is pushed down by the ejection block 2013, so that the top of the stock forms a V-shaped groove that matches the scion, the V-shaped cutter 201 passes through the guide groove 1044 of the second guard plate 1048 to cut, and the scraper 1046 in the guide groove 1044 can help clean the stains on the cutter; Step 4: Spray the incision. After the stock is cut, repeat the operation in step 2 to spray the incision of the stock with a healing agent to keep it moist and improve the healing speed of the stock and scion. Step 5: Carry out grafting. Insert the V-shaped protrusion at the bottom of the cut scion into the V-shaped groove at the top of the stock to make the scion and stock in close contact. After pressing, wrap the grafting film around the interface to ensure that the scion and stock are tightly combined to promote healing.

A spherical groove (1011) is provided on the upper end surface of the first clamp rod (101), and a ball (1021) corresponding to the spherical groove (1011) is provided on the lower end surface of the second clamp rod (102), and the ball (1021) and the second clamp rod (102) are elastically slidably connected via an elastic spring leaf (1022).

10. A method for using an efficient seedling grafting device, applicable to the efficient seedling grafting device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1, cutting the scion, placing the scion between the first clamp head (103) and the second clamp head (104), ensuring that the scion is in the correct position, holding the first clamp rod (101) and the second clamp rod (102) by hand, so that the first clamp head (103) and the second clamp head (104) clamp the scion, continue to use force to make the second clamp rod (102) continue to rotate, drive the V-shaped cutter (201) to cut the scion, so that the lower end of the scion forms a V-shaped protruding incision, when the cutting is completed, due to the presence of the elastic ball (1021) and the spherical groove (1011), the first clamp head (103) and the second clamp head (104) will continue to maintain the clamping force on the scion to ensure the stability of the scion; Step 2: spraying the upper incision. After the scion is cut, press the third clamp rod (301) upwards, and use the lever principle to squeeze the nozzle of the spray pot (302), so that the plant healing agent is sprayed onto the incision of the scion through the spray pot (302), which helps to keep the incision moist and promote healing. After spraying, remove the scion; Step 3, cutting the rootstock, placing the rootstock between the first baffle and the second baffle so that the top of the rootstock is flush with the bottom of the elastic frame (1031), repeating the operation in step 1, clamping the rootstock and cutting, the cut portion of the upper end of the rootstock is pushed down by the ejection block (2013), so that the top of the rootstock forms a V-shaped groove that matches the scion, and the V-shaped cutter (201) passes through the guide groove (1044) of the second guard plate (1048) to cut, and the scraper (1046) in the guide groove (1044) can help remove stains on the cutter; Step 4: spray the incision. After the stock is cut, repeat the operation in step 2 to spray the incision of the stock with the healing agent. Step 5: Grafting: Insert the V-shaped protrusion at the bottom of the scion into the V-shaped groove at the top of the rootstock, so that the scion and the rootstock are in close contact, and then wrap them with the grafting film.
