Description

Technical Field

[0001] This invention relates to the field of forestry technology, and in particular to a grafting rootstock seedling cutting device. Background Technology

[0002] In grafting propagation, the rootstock is the plant or part of the plant that receives the scion. The rootstock has a well-developed root system that anchors the plant, absorbs water and nutrients from the soil, and provides the necessary material basis for the scion's growth. When grafting solanaceous vegetables, both the rootstock and the solanaceous branch need to be cut at an angle, and the two angled surfaces need to fit together perfectly. However, existing rootstock cutting devices require cutting the rootstock and the solanaceous branch sequentially, which makes it impossible to maintain a consistent angle after the cut. This results in the two cut surfaces not fitting together perfectly, making it difficult for the cambium layers to align, hindering healing, affecting nutrient and water transport, and thus reducing the survival rate of the grafted seedlings. Furthermore, after cutting, the two cut surfaces cannot fit together immediately, leading to water loss and contamination, reducing cell activity, and preventing better alignment and healing of the cambium layers of the two branches, ultimately affecting the grafting success rate.

Detailed Implementation

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1

[0035] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a grafting rootstock seedling cutting device. The grafting rootstock seedling cutting device includes a fixing component 100, including a fixing frame 101. The fixing frame 101 is U-shaped and is used to support the entire device. Clamping plates 102 are provided on the inner side of the fixing frame 101. The clamping plates 102 are arc-shaped and there are four of them. They are arranged in pairs, located above and below the inner side of the fixing frame 101. In the initial state, the two clamping plates 102 are in an outward-opening state. The clamping plates 102 are used to clamp and fix the rootstock and solanaceous vegetable branches that need to be cut, so as to prevent them from moving during cutting and to keep them in a coaxial state.

[0036] A stabilizing frame 103 is provided on one side of the clamping plate 102. There are two stabilizing frames 103, located above and below the inside of the fixed frame 101, respectively. The two clamping plates 102 are set as a group on the stabilizing frame 103. The stabilizing frame 103 can move up and down inside the fixed frame 101. A positioning shaft 104 is fixed inside the clamping plate 102. The positioning shaft 104 is movably connected to the inside of the stabilizing frame 103 and is used to support and position the clamping plate 102.

[0037] When cutting, place the rootstock and the stem of the solanaceous vegetable between the two clamps 102 in the upper and lower sets respectively, and make the ends of the two stems contact each other. At this time, the clamps 102 can be rotated inward and the stems are clamped and fixed by the clamps 102. This prevents the stems from moving during the cutting process, which would cause the ends of the two stems to be misaligned, resulting in misalignment when the cut surfaces of the two stems are joined, and thus prevents them from being joined perfectly.

[0038] A first torsion spring 104-1 is fixed to the outside of the positioning shaft 104. The other end of the first torsion spring 104-1 is fixed to the stabilizing frame 103. When the two branches are cut off and fixed, the positioning shaft 104 and the clamping plate 102 can be rotated in opposite directions by the first torsion spring 104-1, and the clamping plate 102 can be separated from the branches.

[0039] The cutting component 200 is located inside the fixed frame 101 and includes two cutting blades 201. The cutting blades 201 are inclined and there are two of them. A connecting plate 202 is fixed to one side of the cutting blade 201. The two cutting blades 201 are fixed above and below one side of the connecting plate 202, respectively. When the connecting plate 202 moves, it will drive the cutting blades 201 to approach the fixed rootstock and the solanaceous vegetable branch, and cut them with the cutting blades 201. The inclination angle of the cut surfaces of the two is kept consistent, so that the two can fit together perfectly when they are grafted and the cambium layers can be aligned, so that the two can heal quickly and improve the survival rate of the grafted seedling.

[0040] A fixed post 203 is fixed on one side of the connecting plate 202. A rotating sleeve 204 is rotatably connected inside the fixed frame 101. The fixed post 203 has a spiral groove 203-1 and a sliding groove 203-2. There are two spiral grooves 203-1 and two sliding grooves 203-2, both located outside the fixed post 203. The sliding groove 203-2 is straight and its two ends are connected to the spiral groove 203-1 respectively. A fixed shaft 205 is inserted into the rotating sleeve 204.

[0041] When the rotating sleeve 204 rotates, it will drive the fixed shaft 205 to slide in the spiral groove 203-1. Through the cooperation of the two, the fixed column 203 can drive the connecting plate 202 and the cutting blade 201 to move, so that the cutting blade 201 can cut the branch. After the branch is cut off, the fixed shaft 205 will enter the sliding groove 203-2. At this time, the connecting plate 202 will drive the cutting blade 201 to move in the opposite direction, so that the cutting blade 201 separates from the cut surface of the branch.

[0042] At the same time, the fixed column 203 moves in the opposite direction, and the fixed shaft 205 slides in the slide groove 203-2, so as not to hinder the reset of the connecting plate 202 and the cutting blade 201. At this time, the fixed shaft 205 will re-enter the spiral groove 203-1. When the rotating sleeve 204 rotates again, the connecting plate 202 and the cutting blade 201 can move again.

[0043] When the fixed shaft 205 enters the slide groove 203-2 from the spiral groove 203-1, a stop bar 203-3 is fixed on the path where the two come into contact. The stop bar 203-3 is inclined on one side inside the spiral groove 203-1, so that it will not hinder the movement of the fixed shaft 205 into the slide groove 203-2. The other side of the stop bar 203-3 is vertical. When the fixed column 203 moves in the opposite direction and causes the fixed shaft 205 to move in the slide groove 203-2, the movement trajectory of the fixed shaft 205 can be limited, so that it can only move in the slide groove 203-2, and avoid it from returning to the spiral groove 203-1.

[0044] The pulling component 300 is located inside the fixed frame 101 and includes two connecting rods 301 located on one side of the stable frame 103. Each connecting rod 301 is connected to one of the two stable frames 103. The ends of the connecting rods 301 are hinged to the stable frames 103 via hinge plates. Both connecting rods 301 are inclined. A connecting post 302 is rotatably connected to the end of the connecting rod 301. The connecting rods 301 are used to connect the ends of the two connecting rods 301. A positioning groove 101-1 is provided inside the fixed frame 101. The connecting post 302 slides in the positioning groove 101-1. The positioning groove 101-1 is used to limit the movement trajectory of the connecting post 302.

[0045] When the cutting blade 201 cuts the branch and moves back to its original position, the connecting post 302 will drive the two connecting rods 301 to move, and the ends of the two connecting rods 301 will bring the upper and lower stabilizing frames 103 closer together. This allows the clamping plate 102 to bring the cut surfaces of the two branches closer together and make the two cut surfaces fit together. At this time, the staff can directly fix the two branches together with tape, which can minimize the time the cut surfaces are exposed to air, reduce the possibility of moisture loss and contamination, maintain cell activity, and allow the cambium layers of the two branches to better align and heal, thereby improving the success rate of grafting.

[0046] It should be noted that since the rootstock is fixed in the ground, it cannot be moved by the clamps 102. Therefore, when the two clamps 102 move the branches, the user needs to adjust the fixing frame 101 downwards as a whole to ensure that the cut surfaces of the two branches can fit together.

[0047] Example 2

[0048] Reference Figures 2-10 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0049] Specifically, the fixing component 100 also includes a pressing component 105. The pressing component 105 includes a force-bearing block 105a fixed to one side of the clamping plate 102. The number of force-bearing blocks 105a corresponds to the number of clamping plates 102. A pressing block 105b is provided on one side of the force-bearing block 105a. One side of the pressing block 105b is arc-shaped and contacts the two force-bearing blocks 105a. A through groove is provided on one side of the stabilizing frame 103. When the stabilizing frame 103 moves up and down, the pressing block 105b can slide relative to each other in the through groove. There are two pressing blocks 105b, which are located in the through grooves of the upper and lower stabilizing frames 103 respectively.

[0050] A fixing rod 105c is fixed on one side of the extrusion block 105b. A connecting frame 105d is sleeved on the outside of the fixing rod 105c. A first spring 105e is fixed at one end of the fixing rod 105c. A positioning rod 105f is fixed at the bottom of the connecting frame 105d. The positioning rod 105f connects and fixes the upper and lower connecting frames 105d.

[0051] When the positioning rod 105f moves, it will drive the connecting frame 105d to move. The connecting frame 105d pushes the fixing rod 105c and the pressing block 105b to move through the first spring 105e, and causes the pressing block 105b to press against the two force blocks 105a. In this way, the force blocks 105a can drive the clamping plate 102 to rotate, thereby allowing the clamping plate 102 to clamp and fix the branches.

[0052] When the clamping plate 102 has finished clamping the branch and can no longer rotate, the positioning rod 105f and the connecting frame 105d are still moving, which will compress the first spring 105e without hindering the normal movement of the positioning rod 105f.

[0053] Specifically, the cutting assembly 200 includes a pusher 206, which includes a rotating rod 206a sleeved on the outside of the rotating sleeve 204. The rotating rod 206a is movably connected to the outside of the rotating sleeve 204. A locking block 206b is inserted into the rotating rod 206a, with one side of the locking block 206b being inclined. The rotating sleeve 204 has multiple locking slots 204-1, which are evenly distributed in a ring on the outside of the rotating sleeve 204. By setting multiple locking slots 204-1, the rotating rod 206a can be rotated to any angle, and the locking block 206b can be engaged with the locking slot 204-1. The two work together to connect the rotating rod 206a and the rotating sleeve 204. When the rotating rod 206a rotates initially, it will drive the rotating sleeve 204 to rotate. When the rotating rod 206a rotates in the opposite direction to reset, it will not drive the rotating sleeve 204 to rotate.

[0054] A mounting frame is fixed to one side of the rotating rod 206a, and the locking block 206b is movably connected to the mounting frame. A seventh spring is fixed to one side of the locking block 206b. The seventh spring is used to apply a pushing force to the locking block 206b, so that the locking block 206b and the locking groove 204-1 are engaged more securely.

[0055] A movable sleeve 206c is fitted on the outer side of the rotating rod 206a. The movable sleeve 206c is movably connected to the outer side of the rotating rod 206a. A moving rod 206d is provided on one side of the movable sleeve 206c. The moving rod 206d is hinged to the movable sleeve 206c through a hinge plate. The other end of the moving rod 206d extends through to the outer side of the fixed frame 101 and is fixed with a force-bearing rod 206e. A push post 206f is fixed on one side of the positioning rod 105f. The push post 206f is relatively short and does not contact the force-bearing rod 206e in the initial state.

[0056] When the positioning rod 105f moves a certain distance and the clamping plate 102 completes the clamping of the branch, the pusher 206f will come into contact with the force rod 206e and push the force rod 206e to move. This causes the force rod 206e to drive the positioning rod 105f to move, thereby causing the positioning rod 105f to drive the rotating rod 206a to rotate, and the rotating rod 206a to drive the rotating sleeve 204 to rotate.

[0057] Specifically, the pulling assembly 300 also includes a pulling member 303, which includes a support rod 303a fixed to one side of the connecting plate 202. A push block 303b is provided at the end of the support rod 303a. The push block 303b is hollow, and a stabilizing shaft is fixed to its lower inner side. The stabilizing shaft is movably connected to the support rod 303a to support and position the push block 303b. A second torsion spring is fixed to the outside of the stabilizing shaft. The other end of the second torsion spring is fixed to the support rod 303a. A stop block 303c is provided on one side of the push block 303b. The stop block 303c contacts the push block 303b to limit the rotation of the push block 303b.

[0058] When the connecting plate 202 drives the cutting blade 201 to cut the anvil, it will simultaneously drive the push block 303b to approach the connecting post 302 via the support rod 303a. When the push block 303b contacts the connecting post 302, it will rotate due to the reverse thrust of the connecting post 302. As the support rod 303a continues to move, the push block 303b will move to the other side of the connecting post 302 and rotate to a vertical state via the second torsion spring.

[0059] When the connecting plate 202 moves in the reverse direction to reset, the push block 303b will contact the connecting post 302 again. At this time, the push block 303b is restricted by the stop block 303c, so that the push block 303b cannot rotate, which will drive the connecting post 302 to move. This allows the connecting post 302 to drive the connecting rod 301 to move, and the clamping plate 102 to drive the two branches closer together.

[0060] A movable column 303d is fixed on one side of the stop block 303c. One end of the movable column 303d extends through to the outside of the fixed frame 101 and is movably connected to the fixed frame 101. A fixed ring is fixed on the top of the support rod 303a. The movable column 303d is movably connected to the fixed ring and the two fit tightly together. This ensures that when the push block 303b is pushed, the stop block 303c will not move due to the push of the push block 303b, but can continuously limit the push block 303b.

[0061] Once the branches are secured, the user can push the movable column 303d to move the stop block 303c, causing the stop block 303c to separate from the push block 303b. This releases the restriction on the push block 303b and allows the push block 303b to release the restriction on the connecting column 302, enabling the connecting column 302 to move in the opposite direction and reset, and also resetting the upper and lower stabilizing frames 103.

[0062] Specifically, a connecting sleeve 106 is fixed to one side of the fixed frame 101. Both ends of the positioning rod 105f pass through the connecting sleeve 106 and are movably connected to it. A handle 107 is fixed to the bottom of the connecting sleeve 106. The handle 107 is convenient for the user to hold and use. A movable column 108 is inserted into the connecting sleeve 106. One end of the movable column 108 is fixed to the positioning rod 105f. During use, the user holds the handle 107 and pushes the movable column 108 to move the positioning rod 105f. As the positioning rod 105f moves, the clamping and fixing of the branches, cutting, and joining the cut surfaces of the branches together can be completed. The operation is convenient and can improve the efficiency of grafting.

[0063] The movable column 108 is tightly connected to the connecting sleeve 106. After use, the movable column 108 can be pulled outward.

[0064] Specifically, four mounting rods 202-1 are fixed to one side of the connecting plate 202, respectively fixed above and below both sides of the connecting plate 202. Two elastic ropes 202-2 are fixed to the ends of the mounting rods 202-1, respectively fixed to the two mounting rods 202-1 on both sides. The elastic ropes 202-2 are elastic. When the cutting blade 201 cuts the branch, the elastic ropes 202-2 will come into contact with the branch and bend due to the reverse thrust of the branch. After the branch is cut, the elastic force of the elastic ropes 202-2 can push the cut branch to move and fall downwards, thereby exposing the cut surfaces of the rootstock and the solanaceous vegetable branches and allowing them to fit together. With the setting of two elastic ropes 202-2, the cut branches of the rootstock and the solanaceous vegetable branches can be pushed away respectively.

[0065] Example 3

[0066] Reference Figures 1-11 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0067] Specifically, a fixed sleeve 205-1 is fixed on one side of the rotating sleeve 204, and the fixed shaft 205 is movably connected to the fixed sleeve 205-1. When the fixed shaft 205 is in contact with the inclined surface of the stop bar, it can move into the fixed sleeve 205-1 and pass over the stop bar. A second spring 205-2 is fixed on one side of the fixed shaft 205, and the other end of the second spring 205-2 is fixed to the inner wall of the fixed sleeve 205-1. The second spring 205-2 is used to apply a thrust to the fixed shaft 205, so that the fixed shaft 205 fits more tightly with the spiral groove 203-1 or the sliding groove 203-2.

[0068] Specifically, a stabilizing column 103-1 is fixed on the stabilizing frame 103, and a stabilizing sleeve 103-2 is fixed inside the stabilizing frame 101. The stabilizing column 103-1 and the stabilizing sleeve 103-2 are movably connected inside the stabilizing frame 103. The two cooperate to support and position the stabilizing frame 103. A third spring 103-3 is fixed at the end of the stabilizing column 103-1. The other end of the third spring 103-3 is fixed to the inner wall of the stabilizing sleeve 103-2. The third spring 103-3 is used to apply tension to the stabilizing column 103-1, so that the stabilizing frame 103 can be reset after movement. There are four of the above structures, which are located on both sides of the two stabilizing frames 103.

[0069] Specifically, a limiting post 202-3 is fixed on one side of the connecting plate 202, and the other end of the limiting post 202-3 extends through to the outside of the fixed frame 101 and is movably connected to the fixed frame 101. There are two limiting posts 202-3, which are fixed at both ends of one side of the connecting plate 202 to limit the movement of the connecting plate 202 and prevent it from deviating during movement.

[0070] A fourth spring 202-4 is fixed on one side of the connecting plate 202, and the other end of the fourth spring 202-4 is fixed to the connecting plate 202. When the cutting blade 201 cuts the rootstock and the branches of the solanaceous vegetables, and the fixed shaft 205 enters the slide groove 203-2, the connecting plate 202 can be pulled in the opposite direction and reset by the fourth spring 202-4.

[0071] The fourth spring 202-4 has a greater elastic force than the third spring 103-3, which ensures that when the connecting plate 202 moves in the reverse direction to reset, the push block 303b can drive the connecting post 302 to move and bring the two branches closer together.

[0072] Specifically, a support column 206e-1 is fixed on one side of the fixed frame 101. The support column 206e-1 is movably connected to the force-bearing rod 206e. There are multiple support columns 206e-1, which are evenly distributed in a straight line on one side of the fixed frame 101 to support and position the force-bearing rod 206e and prevent it from tilting when moving.

[0073] A fifth spring 206e-2 is fixed on one side of the force-bearing rod 206e, and the other end of the fifth spring 206e-2 is fixed to the fixed frame 101. When the push column 206f separates from the force-bearing rod 206e, the fifth spring 206e-2 can push the force-bearing rod 206e and the moving rod 206d to reset, and cause the rotating rod 206a to rotate in the opposite direction to reset.

[0074] In use, the rootstock and the stem of the solanaceous vegetable are placed between the two clamps 102 of the upper and lower sets, respectively, and the ends of the two stems are brought into contact. At this time, the movable column 108 is pushed to move the positioning rod 105f. When the positioning rod 105f moves, it will drive the connecting frame 105d to move. The connecting frame 105d pushes the fixing rod 105c and the squeezing block 105b to move through the first spring 105e, and the squeezing block 105b squeezes the two force blocks 105a. In this way, the clamps 102 can be rotated through the force blocks 105a, and the stems are clamped and fixed by the clamps 102. This prevents the stems from moving during the cutting process, which would cause the ends of the two stems to be misaligned, resulting in misalignment when the cut surfaces of the two stems are joined, and thus prevents them from being perfectly joined.

[0075] As the positioning rod 105f continues to move, it will cause the push rod 206f to contact the force rod 206e and push the force rod 206e to move. This will cause the force rod 206e to move the positioning rod 105f, which in turn will cause the positioning rod 105f to rotate the rotating rod 206a. The rotating rod 206a will then drive the rotating sleeve 204 to rotate. When the rotating sleeve 204 rotates, it will cause the fixed shaft 205 to slide in the spiral groove 203-1. Through the cooperation of the two, the fixed rod 203 can drive the connecting plate 202 and the cutting blade 201 to move, so that the cutting blade 201 can cut the branch. After the branch is cut off, the fixed shaft 205 will enter the sliding groove 203-2. At this time, the connecting plate 202 will drive the cutting blade 201 to move in the opposite direction, so that the cutting blade 201 separates from the cut surface of the branch.

[0076] When the cutting blade 201 cuts the branch and moves back to its original position, the connecting post 302 will drive the two connecting rods 301 to move, and the ends of the two connecting rods 301 will bring the upper and lower stabilizing frames 103 closer together. This allows the clamping plate 102 to bring the cut surfaces of the two branches closer together and make the two cut surfaces fit together. At this time, the staff can directly fix the two branches together with tape, which can minimize the time the cut surfaces are exposed to air, reduce the possibility of moisture loss and contamination, maintain cell activity, and allow the cambium layers of the two branches to better align and heal, thereby improving the success rate of grafting.
