Description

Technical Field

[0001] The invention belongs to the technical field of pepper cultivation devices, and in particular relates to a thornless pepper grafting device and a grafting method. Background Art

[0002] The properties of thornless Zanthoxylum bungeanum are unstable, so grafting is usually used to cultivate thornless Zanthoxylum bungeanum to maintain its excellent properties. Zanthoxylum bungeanum is generally selected as the rootstock during cultivation, and the seedlings are sown and fixed according to a certain row spacing and plant spacing. When the seedlings grow to a certain height, they can be grafted. V-shaped grafting is a common grafting method for Zanthoxylum bungeanum grafting. The V-shaped incision can increase the contact area between the scion and the rootstock, making the healing between the two closer, thereby increasing the success rate of grafting.

[0003] At present, a grafting knife is used for cutting during V-shaped grafting. The existing grafting knife has a simple structure, including a slender blade and a handle. When cutting, the grafting knife is first used to cut downward from the end of the rootstock to form an incision with an angle of about 30 to 45 degrees, and then another downward incision is made from the opposite direction to finally form a V-shaped incision.

[0004] The purpose of the V-shaped incision is to better connect the cambium of the scion and the rootstock. The close combination of the cut surfaces of the rootstock and the scion is the key to a successful grafting. However, the current use of a grafting knife to cut in two times can easily lead to inconsistencies between the two cut surfaces. If the two cut surfaces are inconsistent, it will lead to a mismatch in the growth rates between the scion and the rootstock, thereby affecting the growth and development of the entire plant. Even the gaps or wounds left by inconsistent cut surfaces may become invasion points for pests and diseases, increasing the risk of plant infection. Summary of the invention

DETAILED DESCRIPTION

[0028] The present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection solution of the present invention.

[0029] The properties of thornless Zanthoxylum bungeanum are unstable, so grafting is usually used to cultivate thornless Zanthoxylum bungeanum to maintain its excellent properties. Zanthoxylum bungeanum is generally selected as the rootstock during cultivation, and the seedlings are sown and fixed according to a certain row spacing and plant spacing. When the seedlings grow to a certain height, they can be grafted. V-shaped grafting is a common grafting method for Zanthoxylum bungeanum grafting. The V-shaped incision can increase the contact area between the scion and the rootstock, making the healing between the two closer, thereby increasing the success rate of grafting.

[0030] At present, a grafting knife is used for cutting during V-shaped grafting. The existing grafting knife has a simple structure, including a slender blade and a handle. When cutting, the grafting knife is first used to cut downward from the end of the rootstock to form an incision with an angle of about 30 to 45 degrees, and then another downward incision is made from the opposite direction to finally form a V-shaped incision.

[0031] The purpose of the V-shaped incision is to better connect the cambium of the scion and the rootstock. The close combination of the cut surfaces of the rootstock and the scion is the key to a successful grafting. However, the current use of a grafting knife to cut in two times can easily lead to inconsistencies between the two cut surfaces. If the two cut surfaces are inconsistent, it will lead to a mismatch in the growth rates between the scion and the rootstock, thereby affecting the growth and development of the entire plant. Even the gaps or wounds left by inconsistent cut surfaces may become invasion points for pests and diseases, increasing the risk of plant infection.

[0032] The present invention discloses a thornless pepper grafting device, such as Figure 1-3As shown, it includes: a mounting plate 1, a grafting knife 3, and a control structure; wherein the bottom surface of the mounting plate 1 is provided with two parallel first sliders 2, and the two first sliders 2 can slide in the direction of approaching and moving away from each other; the grafting knife 3 is correspondingly arranged at the bottom of each first slider 2, and the extension lines of the two grafting knives 3 intersect and form a V shape; the control structure includes a bracket 4, a rotating shaft 7, a crank connecting rod assembly, two second sliding blocks 5 and a gear 6, the two second sliding blocks 5 are respectively arranged in parallel on both sides of the surface of the mounting plate 1, each second sliding block 5 is respectively fixedly connected to one of the first sliders 2, and the gear 6 rotates It is arranged between two second sliding blocks 5, and the second sliding block 5 is provided with gear teeth meshing with the gear 6. The bracket 4 is vertically arranged on the top of the mounting plate 1, and the rotating shaft 7 vertically passes through the upper side of the bracket 4 and is rotatably connected with the bracket 4. One end of the crank-connecting rod assembly is connected to the lower end of the rotating shaft 7, and the other end of the crank-connecting rod assembly is fixedly connected to one of the second sliding blocks 5. When the rotating shaft 7 rotates, the two first sliding blocks 2 can be driven to move toward each other through the crank-connecting rod assembly and the second sliding block 5. At this time, when the mounting plate 1 is pressed downward, the two grafting knives 3 arranged at the bottom of the mounting plate 1 can cut a V-shaped section on the end face of the rootstock.

[0033] Therefore, when the thornless prickly ash grafting device disclosed in the present invention is in use, the rotating shaft 7 is driven to rotate manually or electrically, and the connecting rod on the crank connecting rod is driven to slide when the rotating shaft 7 rotates. Because one end of the connecting rod on the crank connecting rod is fixedly connected to one of the second sliding blocks 5, the connecting rod can drive one of the second sliding blocks 5 to slide while sliding, and then drive the other second sliding block 5 to start sliding under the action of the gear 6, and at this time, the sliding directions of the two second sliding blocks 5 are opposite, so at this time, the two first sliding blocks 2 can be driven by the two second sliding blocks 5 to move toward each other, and at this time, the grafting knife 3 connected to the bottom of the two first sliding blocks 2 begins to approach, and at this time, when the entire grafting device is pressed downward by the mounting plate, a V-shaped interface can be formed at the top of the rootstock, and at this time, because the cutting angle and strength of the two grafting knives 3 are uniformly fixed, the final cutting surface can be guaranteed to be consistent, so the subsequent grafting survival rate can be guaranteed.

[0034] Furthermore, the crank-connecting rod assembly disclosed in the present embodiment includes a crank 8 and a connecting rod 9, one end of the crank 8 is hinged to the lower end of the rotating shaft 7, the connecting rod 9 is vertically arranged between the two second sliding blocks 5, one end of the connecting rod 9 is fixedly connected to one of the sliding blocks 5, the second sliding block is provided with a strip groove extending along its length direction, and the other end of the crank 8 is movably connected to the strip groove through a hinge shaft; therefore, when the rotating shaft 7 rotates, the crank 8 hinged thereto is driven to rotate around the rotating shaft 7, and finally, because the other end of the crank 8 is movably connected to the strip groove through the hinge shaft, the crank 8 can drive the connecting rod 9 to perform a linear motion when it rotates around the rotating shaft 7, and finally a second sliding block 5 connected to the connecting rod 9 also performs a linear motion.

[0035] When the pepper stock is cut, the inclination angle of the cut surface needs to be appropriately adjusted according to the diameter of the pepper stock, because when the diameter of the pepper stock changes, in order to make the inclination angle of the V-shaped cut surface adjustable at the same time, the bottom of each first slider 2 disclosed in the present embodiment is hinged with an inclined steel plate 10, each grafting knife 3 is fixed to the lower side end face of the inclined steel plate 10, and an adjustment component for adjusting the inclination angle thereof is also provided between the two inclined steel plates 10. The inclination angles of the two inclined steel plates 10 can be adjusted simultaneously by the adjustment component, so that the inclination angles of the two grafting knives 3 are also changed simultaneously.

[0036] Specifically, the adjustment assembly disclosed in this embodiment includes a vertical steel plate 11, an adjustment rod 12, a connecting rod 13 and a sliding rod 14. The vertical steel plate 11 is vertically arranged on the bottom surface of the mounting plate 1, and the mounting plate 1 is located in the middle of the two oblique steel plates 10. The adjustment rod 12 is arranged horizontally through the vertical steel plate 11. Both ends of the adjustment rod 12 are provided with external threads. Two connecting rods 13 are horizontally arranged on the oblique steel plates 10 and the connecting rods 13 are respectively threadedly connected to the adjusting rods 12. The sliding rod 14 is respectively vertically connected to each connecting rod 13, and one end of the sliding rod 14 away from the connecting rod 13 is slidably connected to the bottom surface of the mounting plate 1. In order to facilitate the rotation of the connecting rod 13, an anti-slip pattern is arranged on the connecting rod 13, so that when the connecting rod 13 is rotated, the connecting rod 13 threadedly connected thereto slides in a direction of approaching or moving away from each other, and finally the inclination angle of the two oblique steel plates 10 is adjusted.

[0037] Furthermore, a vertical cutter 15 is fixedly provided on the bottom surface of the vertical steel plate 11, and the vertical cutter 15 can bear part of the cutting force during cutting, so that the cutting of the two grafting knives 3 is more stable when cutting downwardly, because the cut surface of the stroke is smoother and more consistent.

[0038] A motor 16 is disposed on one side of the rotating shaft 7 disclosed in this embodiment, the output shaft of the motor 16 is vertically upward, and a transmission gear set is disposed between the output shaft of the motor 16 and the rotating shaft 7. Handles 17 are disposed on both sides of the mounting plate 1.

[0039] Vertical support plates 18 are respectively arranged on both sides of the bottom of the mounting plate 1, and mounting blocks 19 are slidably arranged on the opposite sides of the two vertical support plates 18. The mounting blocks 19 can slide in the vertical direction, and arc-shaped clamping plates 21 are connected on the opposite sides of the two mounting blocks 19 through springs 20; because the lower end of the pepper rootstock is fixedly clamped by the two clamping plates 21 during grafting to avoid shaking during cutting, the quality of the cut surface can be guaranteed.

[0040] The present invention also discloses a thornless Zanthoxylum bungeanum grafting method, which is based on the thornless Zanthoxylum bungeanum grafting device as described above and is characterized in that it specifically comprises the following steps:

[0041] Choose healthy, mature, disease-free and insect-free pepper rootstocks and pepper scions;

[0043] Press the switch of the motor 16, and at the same time press the mounting plate 1 to move downward and cut a V-shaped section at the end of the stock;

[0044] Cut one end of the pepper scion into a wedge shape that matches the V-shaped cut of the rootstock, then insert the wedge-shaped end of the pepper scion into the V-shaped cut of the rootstock, and then use a tie to tightly fix the joint between the scion and the rootstock.

[0045] The embodiments described above are only preferred specific implementation methods of the present invention, and the protection scope of the present invention is not limited thereto.
