A scion cutting device for tea tree grafting

Abstract

This invention relates to the field of tea tree grafting technology and discloses a scion cutting device for tea tree grafting, including a base, a cutting structure, a feeding assembly, and a cutting assembly. An electric push rod drives a limiting plate to move, thereby moving the cutting blades to cut the branch. Simultaneously, a magnetic plate limits the cutting, causing the two sets of cutting blades to cut at an angle, facilitating the wedge-shaped cutting of the branch's front end for easier subsequent scion insertion. By using two sets of cutting blades to cut simultaneously on both sides, this method effectively avoids the problems of insufficient support on the cutting surface caused by the thinning of the branch after the first cut in conventional cutting processes. This can lead to incomplete cutting, bending of the wedge-shaped front end during the cutting process, resulting in incomplete cutting, scion peeling, fiber tearing, and an uneven cut surface, ultimately leading to low survival rates.

Description

Technical Field

[0001] This invention relates to the field of tea tree grafting technology, specifically to a scion cutting device for tea tree grafting. Background Technology

[0002] The tea tree belongs to the Theaceae family and the Camellia genus. It is a shrub or small tree with hairless young branches. The leaves are leathery, oblong or elliptical. The leaves of the tea tree can be used to make tea (unlike the oil tea tree), the seeds can be pressed for oil, and the wood of the tea tree is fine-grained and can be used for carving. Its life cycle is divided into seedling stage, juvenile stage, adult stage, and senescent stage. The lifespan of a tree can reach one to two hundred years, but its economic lifespan is generally 40 to 50 years.

[0003] Replacing old varieties with improved clonal varieties and low-yield tea gardens is an inevitable path to the improvement of tea tree varieties. However, when replacing low-yield old tea gardens with improved clonal varieties, the old tea trees must first be dug up, the roots removed, the soil deeply tilled, and small tea seedlings replanted. The newly planted tea gardens will not be able to start producing anything for at least 3 years. The complete transformation and replacement of old tea gardens requires a large investment of financial and material resources. Tea tree grafting is one method to transform and improve the productivity of low-yield old tea gardens, and the cleft grafting method is generally used.

[0004] Chinese Patent Publication No. CN115349363A discloses a "scion cutting device," comprising a base and a cutting plate and scion cutting mechanism mounted on the base. The cutting plate has a V-shaped groove. The scion cutting mechanism includes a cutter, a support base, and a pressure plate hinged to the support base. The cutter is vertically mounted on the pressure plate and used to cut the scion within the V-shaped groove. The cutter includes a straight section and a curved section connected sequentially along the cutting direction. The cutting plate has a clearance notch for accommodating the curved section. In this invention, by setting a V-shaped groove on the cutting plate and a clearance notch for accommodating the curved section, the scion is positioned within the V-shaped groove. The cutter with both straight and curved sections completes the one-time cutting of the scion, ensuring the accuracy of the straight section and the angle of the inclined surface of the grafted portion. This avoids the problem of inaccurate cutting angles caused by the scion rolling on the cutting plate. Furthermore, this invention replaces scion cutting performed on a person's finger, making it safer to use.

[0005] During the scion preparation process, it is usually necessary to prepare both sides. This results in a situation where, after the first side is cut, the thickness of the cut surface of the branch decreases, leading to insufficient support. This makes it easy for the wedge-shaped tip to bend during the cutting process, resulting in incomplete cutting, scion bark peeling, fiber bundle tearing, and an uneven surface, ultimately causing problems such as low survival rate. Therefore, a scion preparation device for tea tree grafting is proposed to solve the above-mentioned problems. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides a scion cutting device for tea tree grafting, which solves the problems of scion bark bursting, fiber bundle tearing, and uneven cut surfaces during cutting, resulting in low survival rates.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: a scion shaving device for tea tree grafting, comprising a base, a cutting structure, a feeding assembly, and a cutting assembly. The cutting structure is disposed on the front of the base for shaving the scion. The feeding assembly is disposed on the top of the base for feeding the scion. The cutting assembly is disposed on both sides of the base for cutting the scion. The cutting structure includes a mounting plate, an electric push rod, a support rod, a magnetic suction plate, a limiting plate, a cutting blade, and a sliding buckle. The mounting plate is connected to both sides of the base. The electric push rod is respectively connected to the top and bottom of the front of the mounting plate. The magnetic suction plate is respectively disposed above and below the base. The support rod is connected to... On both sides of the base, the two ends of the support rod are respectively connected to the corresponding magnetic plates. The limiting plate is at the output end of the electric push rod. The cutting blades are respectively set above and below the base. The cutting blades are slidably connected to the corresponding limiting plates through the sliding buckles on both sides. The cutting blades are magnetically attracted and attached to the magnetic plates. A first telescopic rod is connected to one side of the sliding buckle. Cutting blades are respectively set above and below the front of the base, and one side of the cutting blades is connected to the corresponding first telescopic rod through the connecting block. T-shaped rods are connected to both sides of the base. The inner wall of the T-shaped rod has a limiting groove, and the limiting groove is slidably connected to the corresponding connecting block. The design uses a magnetic plate, causing the cutting blades to gradually rise as they retract, following the magnetic attraction of the plate to facilitate further cutting. An electric push rod moves a limiting plate, which is relatively positioned via a sliding latch. This movement of the cutting blades simultaneously cuts the branch. The magnetic plate's positioning causes both sets of cutting blades to cut at an angle, creating a wedge shape at the branch's tip for easier grafting. This simultaneous cutting from both sides effectively avoids the problem of insufficient support on the cut surface after the first cut, which is common in conventional cutting methods. During the cutting process, the cutting blade bends the front end of the wedge, leading to incomplete cutting, which can cause the scion to peel, the fiber bundles to tear, and the cut surface to become uneven, resulting in a low survival rate. Furthermore, this method of cutting from both sides simultaneously creates a clamping force on the branch to ensure its stability and the quality of the cut surface. While the two sets of cutting blades are making inclined cuts, the first telescopic rod, connected by a sliding buckle, pulls the connecting block and the pruning blade to move together. When the cutting blade finishes cutting, the pruning blade also cuts off the sharp part of the wedge's front end to prevent the sharp part of the scion's front end from becoming too thin, which could easily damage the wedge during grafting and affect the survival rate.

[0010] Preferably, the inclined surfaces of the base at the top and bottom are tilted to the left, and the angles of the two inclined surfaces are consistent with the angles of the corresponding magnetic suction plate and cutting blade. This makes the thickness of the two wedge-shaped sides of the branch inconsistent when the cutting blade cuts the surface. Since the rootstock diameter is usually larger than the scion during grafting, the cut surface on one side of the scion should be slightly thicker than the other side. In this way, after the scion is inserted and the rootstock is split, the clamping force of the rootstock will make the cambium layer on one side of the scion and the cambium layer of the rootstock in close contact.

[0011] Preferably, the top of the base has a placement groove, which is V-shaped. The base has notches on both sides of the placement groove. By setting the placement groove to a V-shape, the branches can be automatically positioned and centered to facilitate cutting.

[0012] Preferably, a positioning plate is provided at one end of the limiting plate. The positioning plate is attached to the sliding buckle and is connected to the limiting plate by bolts. By setting the positioning plate, the cutting tool can be limited to prevent it from falling off the limiting plate. The positioning plate can be removed by turning the bolts to take out the cutting tool for replacement.

[0013] Preferably, the pusher assembly includes a connecting rod, a pull rod, and an arc-shaped push block. The connecting rods are respectively disposed on both sides of the base, and the two ends of the connecting rods are respectively connected to the limiting plates at corresponding positions. By setting the connecting rods to connect the upper and lower limiting plates to make them a whole, the upper and lower cutting blades move synchronously when they move.

[0014] Preferably, the pull rod is connected to the back of the connecting rod, and one end of the pull rod is hinged to an arc-shaped push block. A torsion spring is provided at the hinge of the arc-shaped push block. After the branch is cut, the electric push rod can drive the cutting blade to retract, and at the same time drive the arc-shaped push block on the pull rod on the connecting rod to retract. The elasticity of the torsion spring ensures that the arc-shaped push block is always in contact with the surface of the branch.

[0015] Preferably, the arc-shaped push block bends forward, and the contact surface between the arc-shaped push block and the branch is connected with rubber teeth, which are inclined forward. Since both the arc-shaped push block and the rubber teeth are inclined forward, the friction at the contact point between the arc-shaped push block and the branch is insufficient when retracting, so the branch will not be moved backward. When the electric push rod moves the cutting blade forward again, the pull rod on the connecting rod will move the arc-shaped push block forward. Since the rubber teeth are inclined forward, a large friction force will be generated between the rubber teeth and the branch at this time, so that the arc-shaped push blocks on both sides move forward at the same time, and the branch moves forward through friction.

[0016] Preferably, the cutting assembly includes a second telescopic rod, a limiting buckle, and a cutting blade. The second telescopic rod is connected to both sides of the back of the upper cutting blade. The cutting blade is located at one end of the back of the second telescopic rod. By connecting the cutting blade to the second telescopic rod, the cutting blade descends under the limiting action of the magnetic suction plate, thereby cutting the branch. When the cutting blade has finished cutting the surface, it will also cut off the branch to form a scion for grafting.

[0017] Preferably, the limiting buckle is connected to one side of the second telescopic rod, and the limiting buckle is slidably connected to the support rod at the corresponding position. By setting the limiting buckle to cooperate with the second telescopic rod, the cutting blade is consistent each time, so as to facilitate batch processing.

[0018] Preferably, the cutting blade is connected to the second telescopic rod by bolts. The cutting blade is fixed by bolts to facilitate the replacement of damaged or worn cutting blades in the future. The top of the base has a shallow groove corresponding to the position of the cutting blade to cooperate with the cutting blade for cutting, so as to facilitate the complete severing of branches.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the present invention provides a scion cutting device for tea tree grafting, which has the following beneficial effects:

[0021] 1. This scion-cutting device for tea tree grafting uses an electric pusher to move a limiting plate. A sliding buckle connects to the limiting plate for relative positioning, driving the cutting blades to cut the branch. Simultaneously, a magnetic plate causes the two sets of cutting blades to cut at an angle, facilitating the wedge-shaped cutting of the branch's tip for easier grafting. This simultaneous cutting from both sides effectively avoids the thinning of the cut surface after the first cut, which is a common problem in conventional cutting methods. Insufficient support can easily cause the wedge-shaped tip to bend during the cutting process, resulting in incomplete cutting, peeling of the scion, tearing of fiber bundles, and an uneven cut surface, leading to problems such as low survival rate. Furthermore, while the two sets of cutting blades are making inclined cuts, the first telescopic rod is connected to the connecting block and the pruning blade to move together via a sliding buckle. When the cutting blade finishes cutting, the pruning blade will also cut off the sharp part of the wedge-shaped tip of the branch to prevent the sharp part of the scion's wedge-shaped tip from being too thin, which would easily damage the wedge shape during grafting and affect the survival rate.

[0022] 2. In this scion cutting device used for tea tree grafting, since both the arc-shaped push block and the rubber teeth are tilted forward, the friction between the arc-shaped push block and the branch is insufficient when the branch is retracted, so the branch will not be moved backward. When the electric push rod moves the cutting blade forward again, the pull rod on the connecting rod will move the arc-shaped push block forward. Since the rubber teeth are tilted forward, a large friction force will be generated between the rubber teeth and the branch. This causes the arc-shaped push blocks on both sides to move forward, and the friction force drives the branch forward, thereby pushing the branch to achieve the purpose of automatic feeding.

[0023] 3. The scion cutting device for tea tree grafting is connected to a cutting blade by a second telescopic rod. The cutting blade descends under the limit of the magnetic suction plate, which in turn drives the cutting blade to cut the branch. When the cutting blade finishes cutting, it will also cut off the branch to form a scion for grafting. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a scion-cutting device for tea tree grafting includes a base 1, a cutting structure 2, a feeding assembly 3, and a cutting assembly 4. The cutting structure 2 is located on the front of the base 1 and is used to cut the scion. The feeding assembly 3 is located on the top of the base 1 and is used to push the scion for feeding. The cutting assembly 4 is located on both sides of the base 1 and is used to cut the scion. The cutting structure 2 includes a mounting plate 21, an electric push rod 22, a support rod 23, a magnetic suction plate 24, a limiting plate 25, a cutting blade 26, and a sliding buckle 261. The mounting plate 21 is connected to both sides of the base 1. The electric push rod 22 is connected to the top and bottom of the front of the mounting plate 21, respectively. The magnetic suction plate 24 is located above and below the base 1, respectively, to support the scion. Rod 23 is connected to both sides of base 1, and both ends of support rod 23 are connected to corresponding magnetic plates 24. Limiting plate 25 is at the output end of electric push rod 22. Cutting blades 26 are respectively set above and below base 1. Cutting blades 26 are slidably connected to corresponding limiting plates 25 through sliding buckles 261 on both sides. Cutting blades 26 and magnetic plates 24 are magnetically attracted and attached. By setting magnetic plates 24, the cutting blades 26 will gradually rise with the magnetic attraction of magnetic plates 24 when retracting, so as to facilitate cutting again. The upper and lower slopes of the front of base 1 are inclined to the left, and the two slopes are connected to the corresponding magnetic plates 24 and cutting blades. The consistent angle of inclination of the cutting blade 26 ensures that the thickness of the two wedge-shaped sides of the branch is inconsistent when the cutting blade 26 is used for cutting. Since the rootstock diameter is usually larger than the scion during grafting, the cut surface on one side of the scion should be slightly thicker than the other side. This way, after the scion is inserted and the rootstock is split, the clamping force of the rootstock will cause the cambium layer on one side of the scion to be in close contact with the cambium layer of the rootstock. The top of the base 1 has a placement groove 11, which is V-shaped. The base 1 has notches 12 on both sides of the placement groove 11. By setting the placement groove 11 in a V-shape, the branch can be automatically positioned and centered to facilitate cutting. One end of the limiting plate 25 is provided with a positioning plate 251, which is attached to the sliding buckle 261. The positioning plate 251 is connected to the limiting plate 25 by bolts. The positioning plate 251 can limit the cutting blade 26 to prevent it from falling off the limiting plate 25. The positioning plate 251 can be removed by loosening the bolts to take out the cutting blade 26 for replacement. A first telescopic rod 271 is connected to one side of the sliding buckle 261. Cutting blades 27 are respectively provided on the upper and lower sides of the front of the base 1. One side of the cutting blade 27 is connected to the first telescopic rod 271 at the corresponding position through the connecting block 272. T-shaped rods 273 are connected to both sides of the base 1. The inner wall of the T-shaped rod 273 is provided with a limiting groove 274, and the limiting groove 274 is slidably connected to the connecting block 272 at the corresponding position.

[0036] In this embodiment, by placing the branch in the placement slot 11, the V-shaped structure can automatically position and center the branch for easy cutting. An electric push rod 22 moves the limiting plate 25, and the sliding buckle 261 relative to the limiting plate 25 provides relative positioning. This moves the cutting blade 26 to cut the branch simultaneously. Due to the limiting effect of the magnetic suction plate 24, the two sets of cutting blades 26 perform inclined cutting, facilitating the wedge-shaped cutting of the branch's front end for subsequent grafting. By having two sets of cutting blades 26 cut simultaneously on both sides, the thickness of the branch's cutting surface decreases after the first cut, preventing insufficient support and excessive pressure from the cutting blade during the cutting process. The process involves bending the front end of the wedge, which can lead to incomplete cutting, resulting in issues such as scion bark peeling, fiber bundle tearing, and uneven cut surfaces, leading to low survival rates. Furthermore, this method of cutting from both sides simultaneously creates a clamping force on the branch to ensure stability and quality. While the two sets of cutting blades 26 are making inclined cuts, the first telescopic rod 271, connected by a sliding buckle 261, pulls the connecting block 272 and the cutting blade 27 together. The connection relationship of the connecting block 272 is relatively limited by the limiting groove 274. When the cutting blade 26 finishes cutting, the cutting blade 27 also cuts off the sharp part of the wedge-shaped front end of the branch to prevent the sharp part of the scion's wedge-shaped front end from being too thin, which could easily damage the wedge shape during grafting and affect the survival rate.

[0037] Example 2

[0038] like Figure 1 , Figure 7 , Figure 8As shown, the pusher assembly 3 includes a connecting rod 31, a pull rod 32, and an arc-shaped push block 33. The connecting rod 31 is respectively located on both sides of the base 1, and both ends of the connecting rod 31 are connected to the corresponding limiting plates 25. By connecting the upper and lower limiting plates 25 with the connecting rod 31, they become a whole, so that the upper and lower cutting blades 26 move synchronously. The pull rod 32 is connected to the back of the connecting rod 31, and one end of the pull rod 32 is hinged to the arc-shaped push block 33. A torsion spring is provided at the hinge of the arc-shaped push block 33. By setting the elasticity of the torsion spring, the arc-shaped push block 33 is always in contact with the surface of the branch. After the branch is cut, the electric push rod 22 can drive the cutting blade 26 to retract, and at the same time drive the pull rod 32 on the connecting rod 31 to move the arc-shaped push block 33. When block 33 retracts, the arc-shaped push block 33 bends forward. The contact surface between the arc-shaped push block 33 and the branch is connected by rubber teeth 331, and the rubber teeth 331 are tilted forward. Since both the arc-shaped push block 33 and the rubber teeth 331 are tilted forward, the friction at the contact point between the arc-shaped push block 33 and the branch is insufficient during retraction, so the branch will not be moved backward. When the electric push rod 22 moves the cutting blade 26 forward again, the pull rod 32 on the connecting rod 31 will move the arc-shaped push block 33 forward. Since the rubber teeth 331 are tilted forward, a large friction force will be generated between the rubber teeth 331 and the branch. This causes the arc-shaped push blocks 33 on both sides to move forward, and the branch is moved forward by friction, thereby pushing the branch to achieve the purpose of automatic feeding.

[0039] In this embodiment, after the branch is trimmed, the electric push rod 22 can drive the cutting blade 26 to retract, and at the same time, drive the arc-shaped push block 33 on the pull rod 32 on the connecting rod 31 to retract. Since both the arc-shaped push block 33 and the rubber teeth 331 are tilted forward, the friction between the arc-shaped push block 33 and the branch is insufficient during retraction, so the branch will not be moved backward. When the electric push rod 22 drives the cutting blade 26 forward again, the pull rod 32 on the connecting rod 31 will drive the arc-shaped push block 33 to move forward. Since the rubber teeth 331 are tilted forward, a large friction force will be generated between the rubber teeth 331 and the branch at this time, so that the arc-shaped push blocks 33 on both sides move forward, and the branch moves forward through friction.

[0040] Example 3

[0041] like Figure 6As shown, the cutting assembly 4 includes a second telescopic rod 41, a limiting buckle 42, and a cutting blade 43. The second telescopic rod 41 is connected to both sides of the back of the upper cutting blade 26. The cutting blade 43 is located at one end of the back of the second telescopic rod 41. By connecting the cutting blade 43 to the second telescopic rod 41, the cutting blade 26 descends under the limiting action of the magnetic suction plate 24, while simultaneously driving the cutting blade 43 to descend and cut the branch. When the cutting blade 26 has finished cutting, the cutting blade 43 will also cut off the branch to form a scion for grafting. The limiting buckle 42... The second telescopic rod 41 is connected to one side, and the limiting buckle 42 is slidably connected to the support rod 23 at the corresponding position. By setting the limiting buckle 42 to cooperate with the second telescopic rod 41, the cutting blade 43 is consistent each time, which facilitates batch processing. The cutting blade 43 is connected to the second telescopic rod 41 by bolts. The cutting blade 43 is fixed by bolts to facilitate the replacement of damaged or worn cutting blades 43 in the future. The top of the base 1 has a shallow groove 13 corresponding to the position of the cutting blade 43, which is used to cooperate with the cutting blade 43 to cut, so as to facilitate the complete cutting of branches.

[0042] It is worth noting that after the cutting blade 43 is used, the top of the scion is usually flat. However, in rainy weather, scions with a flat top are prone to water accumulation, which can lead to rot. Therefore, an alternative solution is to use a blade with an angled cut. This way, the top of the scion will be cut with a slanted cut, and the slant should be angled away from the bud. This will allow raindrops to drain away along the slant after falling on the top of the scion, thus effectively preventing water accumulation and rot at the top of the scion.

[0043] In this embodiment, the cutting blade 26 descends under the limiting action of the magnetic suction plate 24, while simultaneously driving the cutting blade 43 to descend and cut the branch. When the cutting blade 26 finishes cutting, the cutting blade 43 also cuts off the branch to form a scion for grafting. Furthermore, by setting the limiting buckle 42 and cooperating with the second telescopic rod 41, the cutting blade 43 is consistent each time, which facilitates batch processing. During this process, the resistance generated when the cutting blade 43 first contacts the branch is greater than the friction force of the rubber teeth 331 contacting the branch, causing the branch to stop moving to ensure that the cutting distance is consistent each time.

[0044] Working principle

[0045] In summary, when using this scion-cutting device for tea tree grafting, the branch is placed in the placement groove 11, and the V-shaped mechanism automatically positions and centers the branch for easy cutting. An electric push rod 22 moves the limiting plate 25, and the sliding buckle 261 relative to the limiting plate 25 provides relative positioning. This allows the cutting blades 26 to move and cut the branch simultaneously. The magnetic suction plate 24 also causes the two sets of cutting blades 26 to cut at an angle, facilitating the wedge-shaped cutting of the branch's tip for subsequent scion insertion. By using two sets of cutting blades 26 to cut simultaneously on both sides, this effectively avoids the uneven cutting surface caused by the first cutting in conventional cutting processes. The reduced thickness results in insufficient support on the branch cutting surface, making it prone to bending the wedge-shaped tip during the cutting process. This leads to incomplete cutting, causing issues like twig peeling, fiber tearing, and an uneven surface. Simultaneous cutting from both sides creates a clamping force on the branch to ensure stability and surface quality. While the two sets of cutting blades 26 are performing inclined cutting, the first telescopic rod 271, connected by a sliding buckle 261, pulls the connecting block 272, which in turn moves with the severing blade 27. The connection of the connecting block 272 is relatively limited by the limiting groove 274. When the cutting blade 26 completes its cutting, the severing blade 27 also cuts off the sharp tip of the branch wedge to prevent... The thinness of the sharp tip of the scion's wedge shape makes it prone to damage during grafting, affecting the survival rate. Furthermore, while the cutting blade 26 descends under the limiting action of the magnetic suction plate 24, it also lowers the cutting blade 43 to cut the branch. When the cutting blade 26 has finished cutting, the cutting blade 43 will also sever the branch to form a scion for grafting. The limiting buckle 42, in conjunction with the second telescopic rod 41, ensures that the cutting blade 43 is consistent each time, facilitating batch processing. After the branch has been cut, the electric push rod 22 can retract the cutting blade 26, simultaneously retracting the arc-shaped push block 33 on the pull rod 32 connected to the connecting rod 31. Since both the arc-shaped push block 33 and the rubber teeth 331 are tilted forward, the retraction is controlled by... If the friction at the contact point between the arc-shaped push block 33 and the branch is insufficient, the branch will not be moved backward. Furthermore, due to the magnetic suction plate 24, the cutting blade 26 gradually rises following the magnetic attraction of the plate 24 during retraction, facilitating further cutting. When the electric push rod 22 moves the cutting blade 26 forward again, the pull rod 32 on the connecting rod 31 moves the arc-shaped push block 33 forward. Since the rubber teeth 331 are tilted forward, a large frictional force is generated between the rubber teeth 331 and the branch. This causes the arc-shaped push blocks 33 on both sides to move forward, simultaneously propelling the branch forward through friction. During this process…The resistance generated when the descending cutting blade 43 first contacts the branch is greater than the frictional force of the rubber teeth 331 contacting the branch, causing the branch to stop moving and ensuring a consistent cutting distance each time. This, combined with the reciprocating motion of the electric push rod 22, drives the various components to perform continuous cutting, thereby improving the efficiency of scion production and ensuring its quality.
