Description

Technical Field

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

[0002] Fruit tree grafting is a commonly used method of asexual plant reproduction and variety improvement. It involves grafting branches or buds from a superior variety of plant to the appropriate part of another plant. By aligning the cambium at the incision and then tying them with a film, the two plants grow together to form a new plant.

[0003] For large branch grafting, thick branches of fruit trees are usually sawed off and multiple branches are grafted at the incisions. At each branch grafting site, the branch epidermis needs to be thinned to expose the phloem, and then two adjacent incisions are cut with a blade. However, the cambium and xylem between the branch incisions are still adhered, and the bark between the two adjacent incisions needs to be manually lifted to facilitate the subsequent insertion of branches. Such manual operation is cumbersome, inconvenient, and inefficient. For this reason, we propose an agricultural seedling grafting equipment. Summary of the Invention

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present invention moves the roller on the knife holder to rotate the knife holder toward the knife sheath, and then the first blade and the second blade cut the phloem and the cambium, and then continue to push the push rod to drive the slide frame to move and then push the baffle, and drive the slider to move in the slide groove through the slide rod, and then drive the bark picking device to move, so that the second blade rotates, picks the cambium at the end of the incision, and separates the cambium from the wood of the branch, and then uses the same method to open a second incision, and picks and separates the cambium from the wood.

At this time, the column moves to the other side to facilitate cutting the second incision. The column contacts and squeezes the arc surface on the other side of the protrusion, driving the protrusion to rotate to the other side, thereby realizing the second blade to rotate to the other side. The direction of rotation of the second blade is opposite to the previous rotation direction, thereby realizing better separation of the cambium and the wood of the branch cortex at the two incisions.

A slide rod 9 is fixed on the block 7, and a baffle 10 is fixed at one end of the slide rod 9 that slides through the slide frame 8. The baffle 10 is located in the slide frame 8. A push rod 11 is rotatably connected to the slide frame 8, and a roller 12 that fits the upper surface of the tool holder 3 is rotatably connected to the bottom of the slide frame 8. A first spring 13 is fixed on the tool holder 3, and the end of the first spring 13 away from the tool holder 3 is fixedly connected to the scabbard 1. A mounting plate 14 is fixed to the end of the scabbard 1, and an arc groove 15 is provided on the mounting plate 14. A skin picking device is provided between the mounting plate 14 and the slider 7, which is used to drive the second blade 5 to rotate to pick the skin of the branch.

[0024] When grafting large branches, the harder bark layer on the surface of the large branch is thinned as needed to expose the phloem, then the handle 2 is held in one hand to pierce the phloem with the tip of the first knife, and then the push rod 11 is pushed to drive the slide frame 8 to move, and then the roller 12 is used to move on the knife holder 3, so that the knife holder 3 rotates toward the scabbard 1, and then the first blade 4 and the second blade 5 cut the phloem and cambium, and then continue to push the push rod 11 to drive the slide frame 8 to move and then push the baffle 10, and drive the slider 7 to move in the slide groove 6 through the slide rod 9, and then drive the bark picking device to move, so that the second blade 5 rotates, and the cambium at the end of the incision is picked up, so that the cambium is separated from the wood part of the branch, and then the second incision is made in the same way, and the cambium is picked up from the wood part. Among them, when making the second incision, it is necessary to first pull the push rod 11 to drive the slide 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 blades of the first blade 4 and the second blade 5 are in the same straight line.

[0025] For details, please refer to Figure 4 、 Figure 5 and Figure 6The leather picking device includes a mounting block 16, and wing plates 17 are symmetrically fixed on both sides of the mounting block 16. The symmetry planes of the two wing plates 17 coincide with the symmetry planes of the mounting block 16. The two wing plates 17 are slidably sleeved with slide rails 18 fixedly connected to the mounting plate 14. The ends of the two wing plates 17 away from the mounting block 16 are fixed with connecting seats 19, and the connecting seats 19 are rotatably connected with connecting rods 20. The ends of the connecting rods 20 away from the connecting seats 19 are rotatably connected to the slider 7. A rotating shaft 21 is rotated through the middle of the mounting block 16, and a V-shaped frame 22 is fixed to the end of the rotating shaft 21 close to the mounting plate 14. The ends of the V-shaped frame 22 are fixed with columns 23, and the two columns 23 are distributed up and down, that is, the V-shaped frame 2 2 is facing the slide rail 18 on the side, and a swing rod 24 is fixed to the end of the rotating shaft 21 away from the mounting plate 14. Two limit blocks 25 are symmetrically fixed on the mounting block 16, and the swing rod 24 is in contact with the limit block 25. A stirring assembly for driving the second blade 5 to rotate is provided in the arc groove 15. The movement of the slider 7 drives the connecting rod 20 to move, and then pushes the wing plate 17 to slide in the slide rail 18, so that the mounting block 16 moves up and down, and then drives the stirring assembly through the column 23 on the V-shaped frame 22, driving the second blade 5 to rotate, so that the cambium of the branch is separated from the wood part, and there is no need to make an incision and then manually separate the two separately. The operation is simpler and more convenient, and the efficiency of making incisions for multiple grafting is improved.

[0026] For details, please refer to Figure 3 、 Figure 4 and Figure 5 , the stirring assembly includes an arc block 26 slidably arranged in the arc groove 15, and a protrusion 27 is fixed on one end of the arc block 26 close to the mounting block 16, and two arc surfaces are symmetrically provided on the protrusion 27, and the two arc surfaces are adapted to the column 23. An end of the arc block 26 away from the mounting plate 14 is fixed with an insertion rod 28 that is slidably inserted with the second blade 5, and a slot 29 that is adapted to the insertion rod 28 is provided on the second blade 5. A steering assembly for rotating the V-shaped block is provided 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 surface and squeezes the protrusion 27, so that the protrusion 27 drives the arc block 26 to slide in the arc groove 15, thereby driving the insertion rod The rod 28 rotates, causing the second blade 5 to rotate, completing the separation of the cambium and the wood at the end of the branch, which is convenient for the subsequent insertion of the grafted branch. Moreover, when the second incision is made, the mounting block 16 is reset, and the V-block is rotated 180 degrees through the steering assembly, so that after the second incision is made, the direction of rotation of the second blade 5 is opposite to the previous rotation direction, thereby achieving a better separation of the cambium and the wood at the branch cortex at the two incisions. At the same time, since a certain gap has been formed in the first incision, when the second incision is formed, the first blade 4 and the second blade 5 will squeeze the epidermis to help the cambium and the wood to be initially separated, so that when the second blade 5 rotates later, the cambium and the wood at the end are separated, and the effect is better.

[0027] For details, please refer to Figure 2 and Figure 5 The steering assembly includes a slide 30 slidably connected to the mounting plate 14, a boss 31 is provided in the upper frame of the slide 30, the boss 31 is in the shape of an inverted triangle, and a notch 32 is provided on the lower frame of the slide 30. The end of the rocker arm 24 away from the rotating shaft 21 is fixedly connected to a first boss 33, and the mounting block 16 is fixedly connected to a second boss 34 located below the rotating shaft 21. A second spring 35 is provided between the first boss 33 and the second boss 34, and the two ends of the second spring 35 are respectively socketed with the first boss 33 and the second boss 34. The ends of the slide formed between the slide 30 and the mounting plate 14 are fixed with magnets 36, which can effectively prevent the slide 30 from shaking at will.

[0028] For details, please refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 There is a certain gap between the end of the tool holder 3 and the mounting plate 14, which is convenient for the rotation of the tool holder 3. At the same time, the upper surface of the tool holder 3 close to the end of the mounting plate 14 is horizontal and parallel to the slide groove 6. A slope 37 is provided in the middle of the upper surface of the tool holder 3. The slope 37 gradually tilts downward from the second blade 5 to the first blade 4. When it is on the middle slope 37, it is convenient for the roller 12 to press the tool holder 3 to rotate. When it moves to the horizontal surface, the tool holder 3 no longer rotates relative to the scabbard 1, thereby facilitating the cooperation of various components to drive the second blade 5 to rotate.

[0029] In this solution, the steering method of the steering assembly in the leather picking device is as follows: when the mounting block 16 drives the V-shaped frame 22 to move upward, the column 23 enters the slide 30 through the notch 32, and then squeezes the boss 31, driving the boss 31 to slide on the mounting plate 14, so that the slide 30 is adsorbed with the magnet 36 on the corresponding side, and then the V-shaped frame 22 moves downward, and the column 23 located below first contacts the frame of the slide 30 at the notch 32. At this time, the V-shaped frame 22 rotates, and under the action of the second spring 35, the V-shaped frame 22 is flipped 180 degrees. At this time, the column 23 moves to the other side, which is convenient for cutting the second incision. The column 23 contacts and squeezes the arc surface on the other side of the protrusion 27, driving the protrusion 27 to rotate to the other side, thereby realizing the rotation of the second blade 5 to the other side.
