Abstract
Description
Technical Field
[0001] This utility model relates to a pruning device, and more particularly to a pruning device for the care of camphor tree seedlings. Background Technology
[0002] Camphor tree, also known as camphor tree, is a common tree species used in landscaping and street greening. It has good ornamental and economic value, and is also used for medicinal and spice production. Pruning is a very important part of the care of camphor tree seedlings, because pruning not only helps to maintain the tree's beautiful shape, but also promotes healthy growth, improves disease resistance, and ensures the long-term stable development of the tree.
[0003] Patent CN218789236U discloses a pruning device for planting seedlings on mountain slopes during high-speed construction. This patent involves two shearing components arranged vertically and rotatably connected to each other. The pruning personnel manually operate these components to prune the seedlings. Simultaneously, by incorporating air pumps, air delivery pipes, and a pesticide storage tank, the pruning personnel can spray pesticides on the seedlings while pruning, thereby improving the survival rate of the pruned seedlings. However, this patent still has shortcomings in practical use: the pruning device still requires the operator to manually drive the shearing components to prune the seedlings. This pruning method easily causes hand pain for the pruning personnel, thus significantly reducing the efficiency of pruning the seedlings.
[0004] Therefore, it is necessary to design a pruning device for the care of camphor tree seedlings to solve the above-mentioned technical problems. Utility Model Content
[0005] In order to overcome the shortcomings of the above-mentioned background technology, the technical problem to be solved is: to provide a pruning device for the care of camphor tree seedlings.
[0006] The technical solution of this utility model is as follows: A pruning device for the care of camphor tree seedlings, comprising a hand handle, a motor, a rotor, a spur gear, a fixed plate, a first shearing component, bolts, a limiting shell, a pressing handle, a limiting rod, a torsion spring, a helical gear, and a second shearing component. The motor is fixedly connected inside the hand handle, and the output shaft of the motor is fixedly connected to the rotor. An electromagnetic coil is located inside the rotor. A spur gear is fixedly connected to one side of the rotor, and a fixed plate is rotatably connected to the other side of the rotor. The bottom of the fixed plate is fixedly connected to the inner wall of the hand handle, and the upper part of the fixed plate extends beyond the top of the hand handle. A first shearing component is fixedly connected to one side of the fixed plate, and a bolt is threadedly connected between the first shearing component and the fixed plate. A limiting shell is fixedly connected to the other side of the fixed plate, and a pressing handle is rotatably connected to the inner wall of the limiting shell. A limiting rod is rotatably connected to one side of the limiting shell, and the limiting rod is fixedly connected to the pressing handle. A torsion spring is fixed between the limiting rod and the pressing handle. A helical gear is fixedly connected to one side of the limiting rod, and a second shearing component is fixedly connected to one side of the helical gear. The helical gear and the spur gear mesh with each other, and the first and second shearing components work together.
[0007] In one embodiment, the device further includes a battery, a controller, and a display screen. The battery is threadedly connected to the lower part of the handle, and the battery insert is inserted into the bottom of the motor. The controller and the display screen are fixed to one side of the battery. The controller is located to the left of the display screen and is electrically connected to the battery and the display screen.
[0008] In one embodiment, the device also includes a protective cover and a magnet. The protective cover is symmetrically fixed to the upper part of the handle, and a magnet is fixed to the top of each protective cover. The two magnets are magnetically attracted to each other.
[0009] In one embodiment, the device further includes a light bulb and a controller 2. The light bulb is fixedly attached to the top of the handle, and the controller 2 is fixedly attached to one side of the handle. The controller 2 is electrically connected to the light bulb.
[0010] In one embodiment, it also includes anti-slip strips, with at least one anti-slip strip fixed to the center of the handle along the perimeter, and each anti-slip strip is distributed in a linear array.
[0011] In one embodiment, the protective cover is made of thermoplastic polyurethane.
[0012] Beneficial effects: 1. By pressing the handle to the left, the starting mechanism of the device is opened. The battery powers the motor. When the motor output shaft rotates, it drives the rotor and spur gear to rotate. The rotation of the spur gear drives the helical gear to move along the arc, thereby driving the two shearing parts to approach and overlap, realizing the reciprocating shearing motion, and achieving the effect of automatic and continuous pruning of seedlings.
[0013] 2. This utility model allows operators to activate the light by pressing and holding the button on the second controller, enabling them to carry out pruning work smoothly even in dimly lit environments, effectively breaking the environmental limitations on pruning.

Detailed Implementation
[0023] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0024] Example: A pruning device for the care of camphor tree seedlings, such as Figures 1-6As shown, the device includes a handle 1, a motor 2, a rotor 3, a spur gear 4, a fixing plate 5, a shearing component 1 6, a bolt 7, a limiting shell 8, a pressing handle 9, a limiting rod 10, a torsion spring 11, a helical gear 12, and a shearing component 2 13. The motor 2 is connected to the inside of the handle 1 by screws. The output shaft of the motor 2 is keyed to the rotor 3. The rotor 3 contains an electromagnetic coil. When the rotor 3 is energized and rotates, it generates a magnetic field. A spur gear 4 is keyed to the front of the rotor 3. The fixing plate 5 is rotatably connected to the rear of the rotor 3, and its lower bottom is connected to the inner wall of the handle 1 by screws. The upper part of the fixing plate 5 extends beyond the top of the handle 1, and its front is connected by screws. A shearing component 6 is attached, and a bolt 7 is threadedly connected between shearing component 6 and fixed plate 5. A limit shell 8 is connected to the right side of fixed plate 5 by screws. A pressing handle 9 is rotatably connected to the top inner wall of limit shell 8. A limit rod 10 is rotatably connected to the front side of limit shell 8. A support rod is welded to the rear side of limit rod 10. The rear side of support rod is connected to pressing handle 9 by screws. A torsion spring 11 is welded between limit rod 10 and pressing handle 9. A helical gear 12 is connected to the front side of limit rod 10 by screws. A shearing component 13 is connected to the rear side of helical gear 12 by screws. Helical gear 12 meshes with spur gear 4. Shearing component 6 and shearing component 13 work together.
[0025] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, it also includes a battery 14, a controller 15, a display screen 16, a protective cover 17, a magnet 18, a light 19, a controller 20, and an anti-slip strip 21. The lower part of the handle 1 is threadedly connected to the battery 14, with the battery 14 inserting into the bottom of the motor 2. The top of the battery 14 is screwed onto the controller 15 and the display screen 16, with the controller 15 located to the left of the display screen 16. The controller 15 is electrically connected to the battery 14 and the display screen 16. The upper part of the handle 1 is symmetrically attached to the protective cover 17 with adhesive. The material is thermoplastic polyurethane, which has good flexibility, allowing the protective cover to fold upward when not in use and bend to both sides when in use to fit the hand tightly. Magnets 18 are glued to the top of both protective covers 17, and the two magnets 18 are magnetically attracted to each other. A light 19 is installed on the top of the handle 1 by screws. A controller 20 is installed on the front side of the middle of the handle 1 by screws. The controller 20 is electrically connected to the light 19. Ten anti-slip strips 21 are glued to the middle of the handle 1 along the whole body, and the ten anti-slip strips 21 are distributed in a straight array.
[0026] When pruning camphor tree seedlings, the operator first grips the device firmly with one hand, according to personal preference, ensuring a secure hold. Then, with the other hand, release the two magnets 18 from their magnetic attraction and bend the two protective covers 17 sequentially: the left cover 17 counter-clockwise and the right cover 17 clockwise. This exposes the inner walls of both covers 17 while their outer walls contact and partially cover the operator's hand. This is because the pruned branches... The branch becomes sharp and detaches from the main branch, then falls downwards. However, the operator's hand may be below the branch, and the sharp branch could scratch the operator's hand. Protected by the guard 17, the operator will not be scratched by the sharp branch while pruning the sapling, thus protecting the operator's hand. Next, the operator manually presses and holds the button on controller 15 to activate battery 14, which powers the motor 2 and other components. The operator then moves the device, bringing the shearing piece 6 and shearing piece 13 close to the sapling branch to be pruned. The sapling is placed between shearing piece 6 and shearing piece 13. Simultaneously, the pressing handle 9 is moved to the left to activate the device's starting mechanism. As the pressing handle 9 moves to the left, it moves the limiting rod 10 to the left, causing the torsion spring 11 to deform. The limiting rod 10 then moves the helical gear 12, causing it to move along an arc. Simultaneously, the spur gear 4 rotates counterclockwise, driving the rotor 3 to rotate. At this point, the internal circuit of the device is connected, and the motor 2 receives power and begins to work, meaning the output shaft of the motor 2 also drives the rotor. When rotor 3 rotates, the electromagnetic coil inside it generates a magnetic field through the current, causing rotor 3 to rotate continuously counterclockwise, which drives spur gear 4 to rotate counterclockwise. At this time, helical gear 12 meshing with spur gear 4 obtains electric driving force, that is, the rotation of motor 2 is converted into rotational motion of helical gear 12 with higher torque, so as to drive the second shearing piece 13 to move quickly and effectively. At this time, the second shearing piece 13 also moves along the arc, and at the same time, the blade of the second shearing piece 13 moves closer to the blade of the first shearing piece 6. Finally, the second shearing piece 13 overlaps with the first shearing piece 6, and at this time the sapling branches are quickly cut.When the operator does not apply pressure to the pressing handle 9, the pressing handle 9 resets under the action of the torsion spring 11, that is, the pressing handle 9 moves to the right, and drives the limiting rod 10 to move to the right. At this time, the helical gear 12 is subjected to a rightward pulling force and a meshing force with the spur gear 4, which causes the magnetic field direction to change, thereby causing the rotor 3 and the spur gear 4 to reverse. That is, the rotor 3 is energized and rotates, driving the spur gear 4 to rotate clockwise. Thus, the rotation of the motor 2 is converted into a higher torque reverse rotation motion of the helical gear 12. At this time, the second shearing piece 13 still moves along the arc, and its blade moves away from the blade of the first shearing piece 6, so that there is space for another sapling branch to be pruned to be placed between the second shearing piece 13 and the first shearing piece 6. When the sapling branch is located between the second shearing piece 13 and the first shearing piece 6, the operator moves the pressing handle 9 to the left again to indirectly start the motor 2 and repeat the above operation to achieve the pruning of the sapling branch.
[0027] With the anti-slip strip 21 in place, the operator's hand is less likely to slip when holding the device, effectively preventing the device from falling and thus protecting it. When the operator needs to prune saplings and the surrounding environment is dim, a light is required. In this case, the operator can press and hold the button on controller 20 to activate light 19. Light 19 is then in illumination mode, providing light to the operator's surroundings and facilitating the pruning of sapling branches. To increase the lighting intensity, the operator can briefly press the button on controller 20 to adjust the light. The lighting intensity of light 19 is such that when light 19 is no longer needed, pressing and holding the button on controller 20 again will turn off light 19. When the pruning of the sapling branches is finished and the device is in a stopped state, the operator bends the two protective covers 17 in sequence, that is, bends the left protective cover 17 clockwise and the right protective cover 17 counterclockwise, so that the two protective covers 17 return to their original positions and remain upright. At this time, the two magnets 18 re-attract each other, and the two protective covers 17 work together to wrap the shearing part 6 and the shearing part 2 13, thus protecting the shearing part 6 and the shearing part 2 13.
