Description

Technical Field

[0001] The present invention relates to the technical field of grafting equipment, and particularly to an agricultural seedling grafting equipment. Background Art

[0002] Fruit tree grafting is a common method for asexual reproduction and variety improvement of plants, that is, branches or buds on plants of excellent varieties are grafted onto appropriate parts of another plant. By aligning the cambium at the incision and then bundling with a film, the two grow together to form a new plant.

[0003] For large branch grafting, usually, the thick branches of the fruit tree are sawn off, and multiple branches are grafted at the incision. At each grafting site of each branch, the epidermis of the branch needs to be thinned first to expose the phloem, and then two adjacent incisions are made with a blade. However, the cambium and xylem between the branch incisions are still adhered, and it is necessary to manually lift the bark between two adjacent incisions, so that the branches can be inserted later. Such manual operation is cumbersome and inconvenient, and the efficiency is low. Therefore, we propose an agricultural seedling grafting equipment. Summary of the Invention

[0007] Preferably, the picking component includes an arc-shaped block slidably arranged in the arc-shaped groove, a convex block is fixed to the end of the arc-shaped block close to the mounting block, two arc-shaped surfaces are symmetrically arranged on the convex block, a plug rod slidably inserted into the second blade is fixed to the end of the arc-shaped block away from the mounting plate, a slot adapted to the plug rod is arranged on the second blade, and a steering component for rotating the V-shaped block is arranged between the mounting block and the mounting plate.

[0008] Preferably, the steering component includes a sliding frame slidably connected to the mounting plate, a convex platform is arranged in the upper frame of the sliding frame, the convex platform is in an inverted triangular shape, a notch is formed in the lower frame of the sliding frame, a first convex column is fixedly connected to the end of the swing rod away from the rotating shaft, a second convex column is fixedly connected to the mounting block and located below the rotating shaft, and a second spring is arranged between the first convex column and the second convex column, and two ends of the second spring are respectively sleeved on the first convex column and the second convex column.

[0009] Preferably, magnets are fixed to the ends of the sliding channels formed between the sliding frame and the mounting plate.

[0010] Preferably, a slope is arranged in the middle of the upper surface of the tool rest, and the slope gradually inclines downward along the direction from the second blade to the first blade.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. In the present invention, the roller moves on the tool rest, causing the tool rest to rotate towards the tool sheath. Then, the first blade and the second blade cut the phloem and the cambium. Then, the push rod is continuously pushed to drive the sliding frame to move, and further drive the baffle. The slider moves in the chute through the slide rod, and then drives the bark picking device to move, causing the second blade to rotate and pick open the cambium at the end of the incision, separating the cambium from the woody part of the branch. Then, the second incision is made in the same way, and the cambium and the woody part are picked open and separated. There is no need to manually separate the two after making the incision, and the operation is simpler and more convenient, improving the efficiency of making incisions for multiple graftings.

[0013] 2. During the process of the installation block driving the V-shaped frame to move upward, the column enters the sliding frame through the notch, then presses the convex platform, driving the convex platform to slide on the mounting plate. After the sliding frame is adsorbed by the magnet on the corresponding side, the V-shaped frame moves downward. The column located below first touches the sliding frame border at the notch. At this time, the V-shaped frame rotates, and under the action of the second spring, a 180-degree flip of the V-shaped frame is achieved. At this time, the column moves to the other side. When cutting the second incision, the column contacts and presses the arc surface on the other side of the convex block, driving the convex block to rotate to the other side, thereby realizing the rotation of the second blade to the other side. The rotation direction of the second blade is opposite to the previous rotation direction. Thus, the branch cortex at the two incision sites realizes a better separation of the cambium and xylem.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-6 , the present invention provides a technical solution: an agricultural seedling grafting device, including a knife sheath 1, a grip rod 2 is fixed outside the knife sheath 1, a rubber pad is provided on the grip rod 2, a knife holder 3 is rotatably connected inside the knife sheath 1, a first blade 4 is fixedly connected below the knife holder 3, a second blade 5 is rotatably connected below the knife holder 3, the cutting edges of the second blade 5 and the first blade 4 are on the same straight line and the second blade 5 is located at the front end of the bottom surface of the knife holder 3, a chute 6 penetrates through the knife sheath 1, a slider 7 and a sliding frame 8 are slidably connected in the chute 6, the slider 7 is closer to the front end of the knife holder 3 than the sliding frame 8, a sliding rod 9 is fixed on the slider 7, one end of the sliding rod 9 that slidably penetrates through the sliding frame 8 is fixed with a baffle 10, the baffle 10 is located inside the sliding frame 8, a push rod 11 is rotatably connected to the sliding frame 8, a roller 12 that fits on the upper surface of the knife holder 3 is rotatably connected to the bottom of the sliding frame 8, a first spring 13 is fixed on the knife holder 3, one end of the first spring 13 away from the knife holder 3 is fixedly connected to the knife sheath 1, a mounting plate 14 is fixed at the end of the knife sheath 1, an arc-shaped groove 15 is provided on the mounting plate 14, and a bark picking device is provided between the mounting plate 14 and the slider 7 for driving the second blade 5 to rotate to pick open the bark of the branch.

[0024] When grafting large branches, according to the need, the harder tree bark on the surface of the large branch is thinned to expose the phloem. Then, hold the grip rod 2 with one hand and pierce the tip of the first knife into the phloem. Then, push the push rod 11 to drive the sliding frame 8 to move, and then move the roller 12 on the knife holder 3 through the roller 12, so that the knife holder 3 rotates relative to the knife sheath 1, and then the first blade 4 and the second blade 5 cut open the phloem and the cambium. Then, continue to push the push rod 11 to drive the sliding frame 8 to move and then push the baffle 10, drive the slider 7 to move in the chute 6 through the sliding rod 9, and then drive the bark picking device to move, so that the second blade 5 rotates to pick open the cambium at the end of the incision, separating the cambium from the woody part of the branch. Then, use the same method to make a second incision and pick open the cambium and the xylem. Among them, when making the second incision, it is necessary to first pull the push rod 11 to drive the sliding frame 8 to move backward to the initial position, and under the action of the first spring 13, the second blade 5 is reset so that the cutting edges of the first blade 4 and the second blade 5 are on the same straight line.

[0025] Specifically, please refer to Figure 4 、 Figure 5 and Figure 6, the peeling device includes a mounting block 16. On both sides of the mounting block 16, wing plates 17 are symmetrically fixed. The symmetry plane of the two wing plates 17 coincides with the symmetry plane of the mounting block 16. Slide rails 18 fixedly connected to the mounting plate 14 are slidably sleeved on both wing plates 17. Connecting seats 19 are fixed to one end of each of the two wing plates 17 away from the mounting block 16. Connecting rods 20 are rotatably connected to the connecting seats 19. The other end of each connecting rod 20 away from the connecting seat 19 is rotatably connected to the slider 7. A rotating shaft 21 is rotatably penetrated through the middle of the mounting block 16. One end of the rotating shaft 21 close to the mounting plate 14 is fixed with a V-shaped frame 22. Columns 23 are fixed to the ends of the V-shaped frame 22. The two columns 23 are distributed vertically, that is, the opening of the V-shaped frame 22 faces the side slide rail 18. One end of the rotating shaft 21 away from the mounting plate 14 is fixed with a swing rod 24. Two limiting blocks 25 are symmetrically fixed on the mounting block 16. The swing rod 24 contacts the limiting blocks 25. A picking component for driving the second blade 5 to rotate is arranged in the arc-shaped groove 15. By the movement of the slider 7, the connecting rod 20 is driven to move, and then the wing plate 17 is pushed to slide in the slide rail 18, so that the mounting block 16 moves up and down. Then, through the column 23 on the V-shaped frame 22, the picking component is driven to drive the second blade 5 to rotate, so that the cambium of the branch is separated from the woody part. After the incision does not need to be made, the two are manually separated separately, and the operation is more simple and convenient, improving the efficiency of making incisions for multiple graftings.

[0026] Specifically, please refer to Figure 3 , Figure 4 and Figure 5 , the picking component includes an arc-shaped block 26 slidably arranged in the arc-shaped groove 15. A convex block 27 is fixed to one end of the arc-shaped block 26 close to the mounting block 16. Two arc-shaped surfaces are symmetrically arranged on the convex block 27. The two arc-shaped surfaces are adapted to the column 23. A plug rod 28 slidably inserted into the second blade 5 is fixed to one end of the arc-shaped block 26 away from the mounting plate 14. A slot 29 adapted to the plug rod 28 is arranged on the second blade 5. A steering component for rotating the V-shaped block is arranged between the mounting block 16 and the mounting plate 14. When the mounting block 16 drives the column 23 to move downward through the V-shaped frame 22, the column 23 contacts the arc-shaped surface and squeezes the convex block 27, so that the convex block 27 drives the arc-shaped block 26 to slide in the arc-shaped groove 15, and then drives the plug rod 28 to rotate, so that the second blade 5 rotates, completing the separation of the cambium and the xylem at the end of the branch, facilitating the insertion of the subsequent grafted branch. Moreover, when making the second incision, the mounting block 16 is reset, and the V-shaped block is rotated 180 degrees through the steering component. After the second incision is made, the rotation direction of the second blade 5 is opposite to the previous rotation direction. Thus, the branch cortex at the two incision positions realizes better separation of the cambium and the xylem. At the same time, since a certain gap has been formed at the first incision, when the second incision is formed, the first blade 4 and the second blade 5 will squeeze the epidermis, which helps the initial separation of the cambium and the xylem, facilitating the separation of the cambium and the xylem at the end when the second blade 5 rotates later, and the effect is better.

[0027] Specifically, please refer to Figure 2 and Figure 5 , the steering assembly includes a carriage 30 slidably connected to the mounting plate 14. A boss 31 is provided inside the upper border of the carriage 30. The boss 31 is in an inverted triangular shape. A notch 32 is formed on the lower border of the carriage 30. One end of the swing rod 24 away from the rotation axis 21 is fixedly connected to a first convex column 33. A second convex column 34 located below the rotation axis 21 is fixedly connected to the mounting block 16. A second spring 35 is provided between the first convex column 33 and the second convex column 34. Both ends of the second spring 35 are sleeved on the first convex column 33 and the second convex column 34 respectively. Magnets 36 are fixed at the ends of the slideway formed between the carriage 30 and the mounting plate 14, which can effectively prevent the carriage 30 from shaking randomly.

[0028] Specifically, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 , there is a certain gap between the end of the tool rest 3 and the mounting plate 14, which is convenient for the tool rest 3 to rotate. At the same time, one end of the upper surface of the tool rest 3 close to the mounting plate 14 is horizontal and parallel to the chute 6. A slope 37 is provided in the middle of the upper surface of the tool rest 3. The slope 37 gradually slopes downward along the direction from the second blade 5 to the first blade 4. When at the middle slope 37, it is convenient for the roller 12 to press the tool rest 3 to rotate. When moving to the horizontal surface, the tool rest 3 no longer rotates relative to the tool sheath 1, thereby facilitating the cooperation of each component to drive the second blade 5 to rotate.

[0029] In this solution, the steering method of the steering assembly in the skin picking device: when the mounting block 16 drives the V-shaped frame 22 to move upward, the column 23 enters the carriage 30 through the notch 32, and then presses the boss 31, driving the boss 31 to slide on the mounting plate 14. After the carriage 30 is adsorbed by the magnet 36 on the corresponding side, then the V-shaped frame 22 moves downward. The column 23 located below first touches the border of the carriage 30 at the notch 32. At this time, the V-shaped frame 22 rotates. Under the action of the second spring 35, a 180-degree flip of the V-shaped frame 22 is realized. At this time, the column 23 moves to the other side. When cutting the second cut, the column 23 contacts and presses the arc surface on the other side of the convex block 27, driving the convex block 27 to rotate to the other side, thereby realizing the rotation of the second blade 5 to the other side.
