Description

Technical Field

[0001] This utility model relates to the field of plant grafting technology, and in particular to a gun-shaped electric grafting device. Background Technology

[0002] Grafting technology is widely used in the variety improvement and high-yield cultivation of fruit trees, vegetables, flowers and other crops. With the expansion of planting scale and the enrichment of crop varieties, there are significant differences in the thickness, hardness and grafting requirements of branches of different crops. For example, citrus branches are thinner and softer, while apple branches are thicker and more lignified, and the corresponding grafting cut shapes (flat cut, wedge cut, tongue cut, etc.) and cutting depth requirements are quite different. In traditional grafting operations, operators need to carry multiple different types of manual grafting knives, frequently changing knives for different branches. This is not only cumbersome and time-consuming, but also prone to blade damage due to collisions during transport, affecting cutting accuracy. Even though some semi-automatic grafting equipment has an electric cutting function, its knives are mostly fixed-mounted, meaning one machine can only perform a single type of cut and cannot adapt to the grafting needs of various branches. To meet the grafting needs of different crops, growers need to purchase multiple grafting machines with different functions, significantly increasing production costs, and the storage and transportation of the equipment are also inconvenient. Therefore, this project studies a gun-shaped electric grafting device that allows for flexible replacement of blades according to branch requirements, is highly adaptable, and easy to operate, so as to flexibly adapt to technician operation and improve operational efficiency.

[0027] The following will refer to the appendix in the embodiments of this utility model. Figure 1-9 The technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0028] Example 1: In order to perform grafting operations on various types of plants, such as roses and tomatoes, this example provides a gun-shaped electric grafting device that integrates multiple cutting blades 6, which can be used for grafting operations on various non-hardwood plants.

[0029] Specifically, it includes: a handheld gun body 1. (See attached document.) Figure 3 As shown, the gun body 1 is equipped with a grip for easy hand operation; the grip has an anti-slip texture design to improve grip stability. The gun body 1 is not a one-piece structure, but rather two outer shells joined together and locked with screws to form a whole. The whole can be disassembled for the assembly of internal components.

[0030] See attached document Figure 4 As shown, the gun body 1 has an insertion plate 2 at its end, and the insertion plate 2 has a blade outlet hole 3. The gun body 1 has an internal mounting chamber, in which a blade disc 4 is rotatably mounted close to the insertion plate 2. The blade disc 4 is driven to rotate by a rotation drive structure. The blade disc 4 has multiple mounting holes 5 arranged in a ring array. Each mounting hole 5 has an axial groove on its inner wall, within which a blade holder 7 is slidably mounted. A blade 6 is mounted on the blade holder 7, allowing the blade 6 to slide axially along the mounting hole 5; the blade 6 is also used to cut branches. The blade 6 is driven by a reciprocating drive structure to move axially back and forth within the mounting hole 5 to achieve the cutting purpose. Furthermore, each blade 6 has a different shape, allowing selection of the appropriate blade 6 to match the branch to be cut.

[0031] In this embodiment, the rotation drive structure mainly includes a rotation motor 9 fixedly installed in the mounting chamber inside the gun body 1. The rotation motor 9 can be a 5840-42BY type micro stepper motor. The output shaft of the rotation motor 9 is connected to a drive shaft via a coupling. The drive shaft is fixedly connected to the shaft of the cutter head 4, thereby driving the cutter head 4 to rotate via the rotation motor 9. Furthermore, the encoder of the rotation motor 9 is electrically connected to a switching button located on the handle of the gun body 1. Each time the switching button is pressed, the rotation motor 9 starts and stops once, and the rotation angle causes the next cutter 6 to move to the position of the cutter outlet 3, realizing the replacement of the cutter 6.

[0032] In this embodiment, the reciprocating drive structure can have two drive forms: The first type is one tool 6 corresponding to one drive: that is, the back side of the tool 4 is provided with a driver 10 corresponding to each tool 6. The driver 10 generates a reciprocating movement drive, so that each tool 6 has an independent drive source.

[0033] As for the driver 10: it can be a miniature electric push rod, which generates reciprocating drive by extending or retracting. It has its own controller and can be electrically connected and controlled independently. It can be a drive motor (refer to the setting of the rotating motor 9). A gear is fixedly installed on the output shaft of the drive motor. The gear meshes with a rack. The rack is fixedly connected to the tool holder 7. The motor can rotate back and forth, thereby generating reciprocating drive force in conjunction with the gear and rack.

[0034] The second method involves multiple cutting tools 6 corresponding to one drive: a mounting base is installed in the mounting chamber inside the gun body 1, and a driver 10 is installed on the mounting base. After the required cutting tool 6 is moved to the position of the cutting hole 3, it is driven by the driver 10.

[0035] For the actuator 10: it can be a miniature electric push rod, which generates reciprocating drive by extending or retracting. It can be a symmetrically arranged dual-set drive motor (refer to the configuration of the rotary motor 9), with half-gears fixedly mounted on the output shafts of both motors. A matching rack is provided between the two sets of half-gears, and the rack slides along the moving direction of the cutter 6 on the tool holder 7. Magnets 101 are provided at both the rack end and the extended end of the push rod, and corresponding iron blocks 103 are provided on the tool holder 7. During forward cutting, the magnet 101 pushes the cutter 6 against the iron block 103 to cut; during pull-back reset, the magnet 101 attracts the iron block 103 and pulls the cutter 6 back to its original position. To further enhance the tightness of the connection between the magnet 101 and the iron block 103, and to prevent the cutter 6 from being jammed by branches during reset and causing the connection to disengage, a rubber sleeve 102 can be provided outside the magnet 101. The rubber sleeve 102 is made of wear-resistant rubber, such as polyurethane rubber, which has excellent wear resistance, corrosion resistance, and good elasticity and tear resistance. (See attached diagram) Figure 8 As shown, the rubber sleeve 102 has a corrugated tube shape, and the iron block 103 on the tool holder 7 also has a groove, with a corresponding annular groove on the inner wall of the groove. When driven in this way, the rubber sleeve 102 is inserted into the groove along with the magnet 101, and the corrugated structure of the rubber sleeve 102 is embedded in the sliding groove, thereby enhancing the tightness of the connection between the push end and the tool 6. During reset, when the tool holder 7 moves to the end point, the rubber sleeve 102 is further pulled and disengaged.

[0036] For a single driver 10, a friction layer is added between the tool holder 7 corresponding to the tool 6 and the contact surface of the slide groove to prevent self-deviation under non-active driving conditions. A top spring can be installed in the slide groove, with the top spring pressing against the side of the tool holder 7 facing the tool outlet 3. In this way, the tool 6 will not move easily due to the restriction of the top spring; and the top spring can also assist the tool 6 in returning to its position in conjunction with the reset of the driver 10.

[0037] The attached diagram shows a single driver 10 structure. However, both of the above reciprocating drive structures can be used as design options, with the specific choice depending on actual production and customer requirements.

[0038] Based on the above technical solution: During operation, the operator presses the switching button according to the branch type, rotating the drive structure to rotate the cutter head 4 and switch the corresponding cutter 6 to the working position. Then, the gun body 1 is adjusted so that the branch is positioned beside the blade outlet 3 of the insert plate 2, perpendicular to the outlet 3. During cutting, the operator holds the branch, and the reciprocating drive structure drives the cutter 6 to move back and forth once, cutting the branch. After cutting, the cutter 6 automatically resets, and the branch is ready for subsequent grafting operations. This equipment allows for flexible replacement of the cutter 6 according to branch requirements, offering strong adaptability. Furthermore, its integrated design combines aesthetics and ease of operation, flexibly adapting to technician operations and improving operational efficiency.

[0039] Example 2: To avoid excessive equipment buildup inside the gun body 1, which could affect installation, maintenance, or even wiring, after comprehensive consideration, referencing the attached... Figure 9 As shown, the cutter head 4 has only three mounting holes 5, corresponding to three types of cutters 6: flat, triangular, and Ω-shaped. Depending on the requirements, the flat cutter 6 can be used to cut flat edges, the triangular cutter 6 to cut wedge-shaped edges, and the Ω-shaped cutter 6 to cut tongue-shaped edges. The three sets of cutters 6 are arranged in a concentrated manner, which not only makes the internal layout of the gun body 1 more reasonable, but also makes it suitable for common grafting cut operations.

[0040] In this embodiment, the rotating motor 9 rotates 120° each time it is turned on and off, which enables the replacement of the next tool 6.

[0041] In Example 3, the insert plate 2, as an external component, is prone to direct contact with branches, leading to deformation and other problems. Furthermore, during cutting, branch debris can easily remain inside the gun body 1 port as the cutter returns to its original position. Therefore, in this example, the insert plate 2 is detachably installed at the end of the gun body 1: the outer edge of the insert plate 2 is provided with external threads, while the inner side of the end of the gun body 1 is provided with internal threads. Through the cooperation of the external and internal threads, the insert plate 2 is screwed onto the end of the gun body 1, thus achieving detachable installation of the insert plate 2 and the gun body 1. This facilitates maintenance and replacement, as well as daily opening and cleaning. It is important to note that the design of the screw-in point and thread length of the insert plate 2 ensures that the cutter hole 3 is located directly above, corresponding to the initial position of the cutter 6. Furthermore, the screwing direction is the same as the direction of rotation of the cutter head 4, so the movement of the cutter head 4 does not affect the tightness of the screwing of the insert plate 2.

[0042] Of course, the insert plate 2 can also be equipped with flange edges and multiple flange holes around it, while the gun body 1 port is equipped with corresponding screw holes. In this way, the insert plate 2 can be locked directly with screws, which can also achieve detachable installation.

[0043] In Example 4, to provide rotational stability for the cutter head 4, multiple single-sided grooved wheels 8 are rotatably mounted around the cutter head 4 inside the gun body 1. The convex edge of one side of each single-sided grooved wheel 8 abuts against the end face of the cutter head 4. Using the single-sided grooved wheels 8 to assist in lifting and limiting the cutter head 4 improves the stability of the cutter head 4's mounting axis positioning and prevents the cutter head 4 from loosening.

[0044] Example 5: After cutting the branches or grafting scions, diluted indoleacetic acid or gibberellin is often sprayed to promote faster healing of the graft union. Therefore, the limited space of the spraying device 1 can be utilized to integrate the spraying structure into a single design: Most of the aforementioned branch cut structures are concentrated at the port of the mounting chamber inside the gun body 1, as shown in the attached diagram. Figure 5As shown, the components are concentrated on the right side, so the left side provides installation space for the spraying structure (the power supply for the rotating motor 9 and other supporting electronic components can be set in the built-in space of the handle, which is also hollow). A partition can also be built in to isolate the cutting structure from the spraying structure, and the partition can also serve as the mounting base surface.

[0045] See attached document Figure 5 Appendix Figure 6 As shown, the gun body 1 also includes a reservoir 11. The upper left end of the reservoir 11 has an injection valve 19 extending out of the gun body 1, through which the drug is injected. A pressure tube 12 is located to the right of the injection valve 19 within the reservoir 11 to prevent injection interference; the pressure tube 12 is open on the right to prevent localized negative pressure and facilitate the insertion and installation of the piston 13. The piston 13 is embedded within the pressure tube 12, and a pull rod 14 extends through the pressure tube 12 and out of the gun body 1, forming the needle piston 13 injector structure; a rubber seal is provided at the through-hole of the pull rod 14 to prevent leakage. A guide tube 18 and a suction tube 17 are respectively located on the upper and lower walls of the left end of the pressure tube 12. The guide tube 18 extends within the gun body 1 and protrudes from the end of the gun body 1 above the insertion plate 2, serving as the drug spray outlet. Both the guide tube 18 and the suction tube 17 are equipped with one-way valves. The one-way valve in the suction tube 17 ensures that the medicine in the reservoir 11 can only be drawn into the pressurization tube 12 from this point and cannot be sprayed out from this point. The one-way valve in the guide tube 18 ensures that the medicine in the reservoir 11 can only be sprayed out from this point and cannot be drawn into the outside air.

[0046] Based on the above technical solution: Pushing lever 14 to the right moves piston 13 to the right, creating negative pressure in pressurization tube 12. The one-way valve of guide tube 18 closes, and the one-way valve of suction tube 17 opens, allowing the liquid to be drawn from reservoir 11 into pressurization tube 12. Pulling lever 14 to the left moves piston 13 to the left, increasing pressure in pressurization tube 12. The one-way valve of suction tube 17 closes, and the one-way valve of guide tube 18 opens, allowing the liquid to flow out and achieving drug injection.

[0047] In this embodiment, the end of the guide tube 18 is set at an angle downward, which also facilitates spraying.

[0048] In this embodiment, the end of the guide pipe 18 is provided with an atomizing nozzle to achieve atomized spraying of the agent and improve the spraying effect.

[0049] In this embodiment, the lever 14 can be pulled by the hook buckle 16, which makes it easier to push and pull the lever 14.

[0050] In this embodiment, a pressure handle 15 can be rotatably mounted on the grip of the gun body 1. Two sets of latches 16 are provided on the extended end of the lever 14, and a straight groove is provided on the upper end of the pressure handle 15. The two latches 16 are located on both sides of the straight groove and have a movable gap. In this way, by holding the grip of the gun body 1, the pressure handle 15 can be pressed, thereby realizing the reciprocating movement of the lever 14.

[0051] Although the lever 14 is restricted by the hydraulic pressure inside the pressure tube 12 and will not move easily, a torsion spring can still be provided between the pressure handle 15 and the rotating part of the gun body 1 for further restriction.

[0052] In this embodiment, refer to the appendix Figure 7 As shown. The pull rod 14 can be a hollow tube, allowing for the addition of medicine to the reservoir 11 without the need for a dedicated injection valve 19. The pull rod 14 is equipped with a threaded cap for closure.

[0053] In Example 6, the branches are placed outside for hand support, which not only easily scratches the hands but also provides insufficient restraint. Therefore, in this example, the insert plate 2 is further improved: See attached document Figure 10 As shown, a cutting tube 20 is provided at the outer end of the cutting tray 2, and the knife outlet 3 on the cutting tray 2 extends through the cutting tube 20. The lower end of the cutting tube 20 has an insertion hole 21, which corresponds vertically to the knife outlet 3 on the cutting tray 2. This allows the cutting to be inserted into the cutting tube through the insertion hole 21, enabling precise cutting, reducing the need for manual handling, and avoiding direct contact with the knife, thus improving safety. The upper end of the cutting tube 20 has a notch that cooperates with the guide tube 18, allowing the pesticide to be sprayed into the cutting tube 20 along the notch, thereby reducing interference with the pesticide spraying at the cutting point of the branch.

[0054] In this solution, the threaded fit is self-locking, or a self-locking nut is provided to prevent the connection from easily coming loose.
