Description

Technical Field

[0001] This invention relates to the field of grafting equipment technology, specifically to an apple grafting fixation and maintenance device based on a two-step grafting process. Background Technology

[0002] Apple trees are typically improved through grafting. Grafting involves cutting a branch or leaf from one plant and grafting it onto another, creating a new plant. After grafting, the graft union needs to be cared for to improve the survival rate and prevent the graft from detaching. Secondary grafting involves using the same branch as rootstock for a second graft, primarily used for dwarfing fruit trees.

[0003] When performing secondary grafting, wedge grafting is often used. Specifically, during cleft grafting or insert grafting, the base of the branch is cut into a wedge shape and inserted into a fan-shaped cut on the rootstock. Then, plastic film is used to wrap the rootstock and branch for maintenance and fixation. This process is done manually and requires a lot of experience to ensure that the shape of the lower end of the branch matches the shape of the cut on the rootstock. This places additional demands on the skill level of the personnel and has a low degree of automation, resulting in low actual grafting efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an apple grafting fixation and maintenance device based on two grafting processes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An apple grafting fixation and maintenance device based on a two-step grafting process includes a notched ring frame, a weight-reducing frame fixedly connected to the notched ring frame, a handle fixedly mounted on the weight-reducing frame, a control panel fixedly connected to the handle, and an independent power supply fixedly connected to the weight-reducing frame. It also includes: A grafting and cutting structure connected to a weight-reducing frame includes two sets of uprights fixedly connected to the weight-reducing frame. Each set of uprights is fixedly connected to a first electric telescopic rod. The moving end of the first electric telescopic rod is fixedly connected to a connector. The connector is connected to a T-groove head via a double-ended screw. The connector and the T-groove head are movably connected. Nuts are installed at both ends of the double-ended screw. A connecting plate is fixedly connected to the T-groove head. A first V-shaped bevel cutter is fixedly connected to both sets of connecting plates. An impact plate is fixedly connected to the first V-shaped bevel cutter. A second V-shaped bevel cutter is fixedly connected to both sets of connecting plates. The first V-shaped bevel cutter and the second V-shaped bevel cutter have the same inclination angle. The blade angle of the first V-shaped bevel cutter and the blade angle of the second V-shaped bevel cutter are the same. The second V-shaped bevel cutter is positioned above the first V-shaped bevel cutter. A branch limiting structure that is fixedly connected to the weight-reducing frame; A membrane curing structure connected to the notched ring frame; A material-shifting structure connected to a weight-reducing frame, wherein the material-shifting structure is connected to the weight-reducing frame and is movably connected to an impact plate.

[0006] As a further improvement of the present invention: the branch limiting structure includes a circular hole frame fixedly connected to the weight reduction frame, the circular hole frame having a circular hole, the circular hole being positioned above the second V-shaped oblique cutter, and an oblique tube coaxially arranged with the circular hole being fixedly installed at the lower end of the circular hole frame.

[0007] As a further improvement of the present invention: the membrane curing structure includes two sets of first motors fixedly installed on the notched ring frame. The output shaft of each set of first motors is fixedly connected to a gear. The two sets of gears mesh together to connect to a notched gear ring. The notched gear ring is rotatably installed inside the notched ring frame. The notched gear ring is coaxially fixedly connected to a notched ring plate. The notched ring plate is rotatably connected to the notched ring frame. The notched ring plate is fixedly connected to an anti-slip shaft. A membrane wheel is rotatably installed on the anti-slip shaft. A brake ring is coaxially fixedly connected to the anti-slip shaft. The brake ring is rotatably connected to the membrane wheel. A curing membrane layer is provided on the membrane wheel.

[0008] As a further improvement of the present invention: the material feeding structure includes a support frame fixedly connected to the weight reduction frame, a hydraulic cylinder fixedly connected to the support frame, a first piston slidably connected to the hydraulic cylinder, a spring fixedly connected to the first piston and the hydraulic cylinder, the spring being disposed inside the hydraulic cylinder, a guide pipe being connected to the hydraulic cylinder, a support ring being fixedly installed on the outer wall of the guide pipe, the support ring being fixedly connected to two sets of uprights, a second piston slidably connected to the guide pipe, one end of the second piston being disposed outside the guide pipe being movably connected to an impact plate, a hinge plate being hinged to the end of the first piston away from the hydraulic cylinder, and a feeding block hinged to the hinge plate being hinged to the two sets of uprights.

[0009] As a further improvement of the present invention: the actuating block is provided with a cam surface, and the actuating block is symmetrically provided with inclined surfaces that are adapted to the shape of the first V-shaped oblique cutter.

[0010] As a further improvement of the present invention: the weight-reducing frame is provided with two sets of symmetrically arranged weight-reducing through slots.

[0011] As a further improvement of the present invention: the weight-reducing frame is fixedly connected to a bracket that is slidably connected to the first V-shaped oblique cutter, and the weight-reducing frame is fixedly connected to a V-shaped indicator frame, the lower end face of the V-shaped indicator frame being flush with the lower end face of the weight-reducing frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are: In use, place the weight-reducing frame onto the rootstock using the handle, and place the branch to be processed into the branch limiting structure. Then, the first electric telescopic rod drives the connecting head to move, which in turn moves the T-groove head, thereby moving the connecting plate. The connecting plate then moves the first V-shaped oblique cutter and the second V-shaped oblique cutter diagonally downwards, causing the first V-shaped oblique cutter to make a cut on the rootstock, while the second V-shaped oblique cutter makes an oblique cut on the lower end of the branch. Since the first and second V-shaped oblique cutters have the same inclination angle, the included angle of the blade of the first V-shaped oblique cutter and the second V-shaped oblique cutter are the same. The two V-shaped oblique cutting blades have the same blade angle, creating a cut surface at the lower end of the branch that matches the shape of the rootstock cut. The branch is then removed from the branch-limiting structure. As the first electric telescopic rod drives the connector to rise, the first V-shaped oblique cutting blade rises and detaches from the rootstock. When the material-dispensing structure is pressed by the impact plate moving with the first V-shaped oblique cutting blade, it dispenses any remaining material from the blade. The lower end of the processed branch is then aligned with the rootstock cut. Finally, the film-wrapping structure performs a wrapping film operation around the rootstock to secure the branch. This invention, through the coordinated use of the grafting cutting structure, branch-limiting structure, film-wrapping structure, and material-dispensing structure, replaces manual grafting and cutting of rootstocks and branches, reducing the need for skilled personnel, improving cutting accuracy, and increasing grafting speed and overall efficiency through automated wrapping film operation, while also reducing the technical requirements for personnel.

[0023] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0024] Example 1, see Figures 1-10 As shown, an apple grafting fixation and maintenance device based on a two-grafting process includes a notched ring frame 1, a weight-reducing frame 2 fixedly connected to the notched ring frame 1, a handle 3 fixedly installed on the weight-reducing frame 2, a control panel 4 fixedly connected to the handle 3, and an independent power supply 5 fixedly connected to the weight-reducing frame 2. It also includes: The grafting and cutting structure 6 is connected to the weight-reducing frame 2. The grafting and cutting structure 6 includes two sets of uprights 7 fixedly connected to the weight-reducing frame 2. Each set of uprights 7 is fixedly connected to a first electric telescopic rod 8. The moving end of the first electric telescopic rod 8 is fixedly connected to a connector 9. The connector 9 is connected to a T-groove head 11 through a double-ended screw 10. The connector 9 and the T-groove head 11 are movably connected. Nuts 12 are installed at both ends of the double-ended screw 10. The T-groove head 11 and the connector 9 can be disassembled by removing the nuts 12 and the double-ended screw 10. The T-groove head 11 is fixedly connected to a connecting plate 13. Two sets of connecting plates 13 are jointly fixedly connected to a first V-shaped oblique cutter 14. The first V-shaped oblique cutter 14 is fixedly connected to an impact plate 15. Two sets of connecting plates 13 are jointly fixedly connected to a second V-shaped oblique cutter 16. The first V-shaped oblique cutter 14 and the second V-shaped oblique cutter 16 have the same inclination angle. The blade angle of the first V-shaped oblique cutter 14 and the blade angle of the second V-shaped oblique cutter 16 are the same. The second V-shaped oblique cutter 16 is positioned above the first V-shaped oblique cutter 14. Branch limiting structure 17 is fixedly connected to the weight reduction frame 2; The membrane curing structure 18 is connected to the notched ring frame 1; The material-pushing structure 19 is connected to the weight-reducing frame 2 and is movably connected to the impact plate 15.

[0025] In use, the weight-reducing frame 2 is placed on the rootstock using handle 3, and the branch to be processed is placed into the branch limiting structure 17. Then, the first electric telescopic rod 8 drives the connecting head 9 to move, which in turn drives the T-groove head 11 to move, thereby driving the connecting plate 13 to move. The connecting plate 13 drives the first V-shaped oblique cutter 14 and the second V-shaped oblique cutter 16 to move obliquely downward, so that the first V-shaped oblique cutter 14 cuts a notch on the rootstock, while the second V-shaped oblique cutter 16 performs oblique cutting on the lower end of the branch. Since the first V-shaped oblique cutter 14 and the second V-shaped oblique cutter 16 have the same inclination angle, the blade of the first V-shaped oblique cutter 14 is clamped. The angle between the blades of the first V-shaped oblique cutter 14 and the second V-shaped oblique cutter 16 is the same, so that the lower end of the branch forms a cut surface that matches the shape of the rootstock cut. Then the branch is taken out from the branch limiting structure 17. As the first electric telescopic rod 8 drives the connecting head 9 to rise, the first V-shaped oblique cutter 14 rises and separates from the rootstock. When the material-pushing structure 19 is pressed by the impact plate 15 that moves with the first V-shaped oblique cutter 14, the material-pushing structure 19 pushes the residual material in the first V-shaped oblique cutter 14. Then the lower end of the processed branch is connected to the cut of the rootstock. After that, the film-wrapping maintenance structure 18 performs a wrapping film operation on the rootstock to fix the branch. This invention utilizes a combination of grafting and cutting structure 6, branch limiting structure 17, film wrapping and maintenance structure 18, and material feeding structure 19 to replace manual grafting and cutting operations on rootstocks and branches. This reduces the need for skilled personnel, improves cutting accuracy, and increases grafting speed and overall grafting efficiency by automatically performing a wrapping operation, while also reducing the technical requirements for personnel.

[0026] In one embodiment, the branch limiting structure 17 includes a circular hole frame 20 fixedly connected to the weight-reducing frame 2. The circular hole frame 20 provides space for manual branch insertion by bending away from the weight-reducing frame 2. A circular hole 21 is provided on the circular hole frame 20, positioned above the second V-shaped oblique cutter 16. A slanted tube 22, coaxial with the circular hole 21, is fixedly installed at the lower end of the circular hole frame 20. Under normal circumstances, the slanted tube 22 is located on the outside of the suspended section, away from the rootstock. Both the circular hole 21 and the slanted tube 22 restrict branch movement, thereby facilitating stable and accurate cutting of the branches by the second V-shaped oblique cutter 16.

[0027] In one embodiment, the membrane curing structure 18 includes two sets of first motors 23 fixedly mounted on the notched ring frame 1. The output shaft of each set of first motors 23 is fixedly connected to a gear 24. The circumferential distribution angle of the two sets of gears 24 is greater than the central angle of the notch on the notched gear ring 25. The two sets of gears 24 mesh together with a notched gear ring 25. The notched gear ring 25 is rotatably mounted inside the notched ring frame 1. The notched gear ring 25 is coaxially fixedly connected to a notched ring plate 26. The notched ring plate 26 is rotatably connected to the notched ring frame 1. The notched ring plate 26 is fixedly connected to an anti-slip shaft 27. A membrane wheel 28 is rotatably mounted on the anti-slip shaft 27. A brake ring 29 is coaxially fixedly connected to the anti-slip shaft 27. The brake ring 29 is rotatably connected to the membrane wheel 28. A curing membrane layer 30 is provided on the membrane wheel 28. The first motor 23 drives the gear 24 to rotate, the gear 24 drives the notched gear ring 25 to rotate, and the notched gear ring 25 drives the notched ring plate 26 to rotate. During this period, at least one set of gears 24 and the notched gear ring 25 are engaged to ensure that the notched ring plate 26 can rotate continuously and stably. The rotation of the notched ring plate 26 drives the anti-slip shaft 27 to rotate, and the anti-slip shaft 27 further drives the film wheel 28 to perform a wrapping operation. Due to the friction between the brake ring 29 and the film wheel 28, the brake ring 29 can effectively prevent the film wheel 28 from rotating excessively due to inertia during the rotation of the film wheel 28, thereby ensuring that the curing film layer 30 is tightly attached to the rootstock surface under the drive of the film wheel 28, completing the fixation and curing operation of the grafting part.

[0028] In one embodiment, the material feeding structure 19 includes a support frame 31 fixedly connected to the weight reduction frame 2. A hydraulic cylinder 32 is fixedly connected to the support frame 31. A first piston 33 is slidably connected to the hydraulic cylinder 32. A spring 34 is fixedly connected to both the first piston 33 and the hydraulic cylinder 32. The spring 34 is disposed inside the hydraulic cylinder 32. A guide pipe 35 is connected to the hydraulic cylinder 32. A support ring 44 is fixedly installed on the outer wall of the guide pipe 35. The support ring 44 is fixedly connected to two sets of uprights 7. The guide pipe 35 is filled with hydraulic oil. The chamber connecting the hydraulic cylinder 32 and the guide pipe 35 is filled with hydraulic oil. A second piston 36 is slidably connected to the guide pipe 35. One end of the second piston 36 located outside the guide pipe 35 is movably connected to an impact plate 15. A hinge plate 43 is hinged to the end of the first piston 33 away from the hydraulic cylinder 32. A feeding block 37 hinged to the hinge plate 43 is hinged to the two sets of uprights 7. When the impact plate 15 moves upward, it applies pressure to the second piston 36 in the feeding structure 19. The second piston 36 transmits the pressure to the first piston 33 in the hydraulic cylinder 32 through the hydraulic oil in the guide pipe 35. Under the pressure, the first piston 33 overcomes the elastic force of the spring 34 and moves away from the hinge plate 43, while pulling the hinge plate 43 to rotate. The rotation of the hinge plate 43 further drives the agitator block 37 to swing. The agitator block 37 removes the residual material from the first V-shaped oblique cutter 14, effectively avoiding the accumulation of residual material that affects the cutting accuracy, and also improving the automation level of the equipment and reducing manual intervention.

[0029] In one embodiment, the actuating block 37 is provided with a cam surface 38, and the actuating block 37 is symmetrically provided with inclined surfaces 39 that are adapted to the shape of the first V-shaped oblique cutter 14. By providing the cam surface 38 on the actuating block 37, the residual material is actuated away from the first V-shaped oblique cutter 14, and the inclined surfaces 39 on the actuating block 37 are provided so that the shape of the actuating block 37 is adapted to the shape of the first V-shaped oblique cutter 14.

[0030] In one embodiment, the weight-reducing frame 2 has two sets of symmetrically arranged weight-reducing slots 40. By providing the weight-reducing slots 40, the overall weight of the device is reduced.

[0031] Example 2, based on Example 1, see [link / reference] Figure 1The weight-reducing frame 2 is fixedly connected to a bracket 41 that is slidably connected to the first V-shaped oblique cutter 14. The weight-reducing frame 2 is also fixedly connected to a V-shaped indicator 42, the lower end face of which is flush with the lower end face of the weight-reducing frame 2. By attaching the V-shaped indicator 42 to the anvil, it indicates the portion of the anvil to be cut by the first V-shaped oblique cutter 14. The flush design of the V-shaped indicator 42 provides the operator with a visual reference for the cutting position, ensuring that the cutting depth and angle of the first V-shaped oblique cutter 14 meet expectations. This design not only simplifies the operation process but also significantly improves cutting accuracy, making it particularly suitable for scenarios with high cutting requirements. Furthermore, the bracket 41 supports the first V-shaped oblique cutter 14 through a sliding connection, effectively reducing vibration and offset during cutter movement, thereby further ensuring cutting stability.

[0032] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
