Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and horticultural tools, and in particular to a handheld portable fruit tree pruning device. Background Technology

[0002] A handheld portable fruit tree pruning device is a lightweight tool specifically designed for fruit tree pruning. It typically integrates a power system such as electric or lithium battery drive, a sharp cutting blade, and an ergonomic handle structure, allowing for flexible pruning of branches of varying thicknesses. Its portability is reflected in its compact size and light weight, making it easy for operators to hold and move quickly among the trees. It also features safety features such as an automatic locking function and a non-slip grip, improving pruning efficiency while ensuring safety during use. Suitable for daily branch pruning and shaping in orchards, it effectively reduces manual labor intensity.

[0003] This handheld portable fruit tree pruning device is driven by a power system. Electric or lithium-ion models convert electrical energy into mechanical energy via a motor, while fuel-powered models utilize an internal combustion engine. This power is transmitted through a transmission mechanism to the sharp cutting components. When the operator grips the handle to start the device and aligns the cutting edge with the fruit tree branch, the power drives the blade to close rapidly. With its powerful shearing force and sharp edge, it instantly cuts the branch. Simultaneously, the device's built-in control system adjusts the power output to accommodate branches of varying thicknesses.

[0004] However, some existing handheld portable fruit tree pruning devices suffer from insufficient protection for the blades during use. Some devices lack a stable blade storage structure after operation, leaving the sharp blades exposed. This not only makes them prone to wear and tear from collisions with other objects during transport, shortening their lifespan, but also poses a safety hazard, as they could easily injure the user or those nearby. Other pruning devices, while equipped with simple storage slots, suffer from poor sealing and insecure fixing, allowing the blades to loosen and fall off in bumpy conditions, failing to provide effective protection. This affects the tool's safety and durability and causes considerable inconvenience to the user. Therefore, a handheld portable fruit tree pruning device is proposed to address these issues.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1 to 3 This utility model provides an embodiment of a handheld portable fruit tree pruning device, comprising a power chamber 1. Two connecting shafts 2 are fixedly connected to the bottom of the power chamber 1. The two connecting shafts 2 are made of alloy steel, and their hardness and wear resistance are enhanced through high-precision machining and heat treatment processes, ensuring efficient and reliable operation of the pruning device. Protective plates 3 are fixedly connected to the front and rear sides of the power chamber 1 to protect the power components inside the power chamber 1 and the safety of the operator. At the same time, the protective plates 3 also enhance the structural strength of the power chamber 1, providing cushioning and protection in the event of accidental collisions, thus extending the service life of the pruning device. Two contraction columns 4 are fixedly connected to the inner walls of the bottom of each of the two protective plates 3. When subjected to external force, the contraction columns 4 can be compressed or extended.

[0027] Limiting strips 5 are fixedly connected to the opposite sides of the two contraction columns 4. During the extension and retraction of the contraction columns 4, the limiting strips 5, in conjunction with relevant components, ensure that the contraction columns 4 move within a safe stroke range, guaranteeing the stability and reliability of the device structure. Slider blocks 6 are fixedly connected to the opposite sides of multiple limiting strips 5. During device operation, the sliders 6, guided by the limiting strips 5, drive the control strip 7 to slide along a predetermined direction. The sliders 6 make the sliding of the control strip 7 smoother and more precise, improving the operator's control over the device. Control strips 7 are fixedly connected to the opposite sides of multiple sliders 6. The operator can control the sliding of the limiting strips 5 by pushing or rotating the control strips 7, thereby adjusting the extension and retraction degree of the contraction columns 4. Springs 8 are fitted around the exterior of multiple contraction columns 4. The main function of the springs 8 is to provide elastic restoring force and buffering effect for the contraction columns 4. When the contraction columns 4 are compressed by external force, the springs 8 compress and store elastic potential energy; when the external force disappears, the springs 8 release the elastic potential energy, pushing the contraction columns 4 to return to their original position.

[0028] Both ends of the two connecting shafts 2 are fixedly connected to a fixing plate 9. The stable installation of the fixing plate 9 ensures the reliability of power transmission, enabling the transmission components to stably receive and transmit power, and ensuring the normal operation of the pruning device. A handle 10 is fixedly connected to the bottom of the power chamber 1. The handle 10 is made of ergonomically designed engineering plastic or rubber and is fixedly connected to the bottom of the power chamber 1 by injection molding or bonding. A connecting block 11 is fixedly connected to the bottom of the handle 10. The shape and size of the connecting block 11 are designed according to the interface of the battery compartment 12, and it is used to connect and fix with the battery compartment 12. The bottom of the connecting block 11 is fixedly connected to the battery compartment 12, providing power to the motor and other components inside the power chamber 1. Its detachable design facilitates battery replacement by the user, ensuring continuous power supply during long-term operation. A replacement assembly is fixedly connected to the top of the power chamber 1.

[0029] Reference Figures 4 to 6 The replacement components include two fixed disks 26, whose bottom ends are externally fixedly connected to the top of the power chamber 1. The rotational power generated by the motor inside the power chamber 1 can be efficiently transmitted to the fixed disks 26, thereby driving the connected power column 18 and other components to work, providing reliable power support for the pruning operation. One of the two fixed disks 26 is rotatably connected to the rear side of the power column 18. The power column 18 has a hollow internal structure and is designed with threads that fit the nut 19. Its bottom end is connected to the output shaft of the motor inside the power chamber 1 via a coupling. The top inner wall of the power column 18 is threaded with a nut 19. The operator can adjust the position of the pressure plate 20 by rotating the nut 19, thereby controlling the degree of pressure of the limit block 21 on the rotating cutter head 24, realizing the locking and unlocking of the rotating cutter head 24, facilitating the replacement and adjustment of the cutter.

[0030] A pressure plate 20 is rotatably connected to the bottom end of the nut 19. When the nut 19 moves axially along the power column 18, the pressure plate 20 moves up and down accordingly. However, due to the action of the thrust bearing, the pressure plate 20 does not rotate with the nut 19. Two limiting blocks 21 are fixedly connected to the bottom end of the pressure plate 20. When the pressure plate 20 is pressed down, the protrusions of the limiting blocks 21 will engage in the grooves of the rotating cutter head 24, thereby limiting the circumferential movement of the rotating cutter head 24. Two retractable columns 22 are fixedly connected to the inner front wall of the power column 18. When the retractable columns 22 extend or retract, they can drive the limiting columns 23 to adjust the distance between the rotating cutter heads 24. The precise control of the retractable columns 22 ensures that the position adjustment of the rotating cutter head 24 is accurate and reliable. Limiting columns 23 are fixedly connected to the rear side of both retractable columns 22. When the retractable columns 22 drive the limiting columns 23 to move, the limiting columns 23 can accurately transmit power to the rotating cutter head 24, so that the rotating cutter head 24 moves synchronously with the limiting columns 23.

[0031] Two limiting posts 23 are externally fixedly connected to rotating cutter heads 24. When the power post 18 rotates, the rotating cutter head 24 rotates around the axis of the power post 18 through the transmission of components such as the nut 19, pressure plate 20, and limiting block 21. Two retracting posts 22 are each externally fitted with springs 25. When the retracting post 22 is compressed by an external force, the springs 25 are compressed and store elastic potential energy; when the external force disappears, the springs 25 release the elastic potential energy, pushing the retracting post 22 back to its original position. Two fixed discs 26 are fixedly connected to the other front side with fixed cutter heads 27. The blade design of the fixed cutter head 27 is adapted to match the blade of the rotating cutter head 24, forming a shearing pair. During pruning operations, the fixed cutter head 27 remains stationary, while the rotating cutter head 24 rotates around the axis of the power post 18; the two work together to prune the branches.

[0032] Reference Figures 1 to 3 Multiple retractable columns 13 are fixedly connected to the outer inner wall of the battery compartment 12. Each retractable column 13 has a limiting column 14 fixedly connected to its opposite side. When the retractable columns 13 extend or retract, the limiting column 14 moves accordingly. A baffle 15 is fixedly connected to the rear side of one of the two protective plates 3. The baffle 15 is made of high-strength engineering plastic injection molding and can buffer external forces and protect internal components from damage in the event of an accidental collision. A limiting plate 16 is slidably connected to the inner wall of the baffle 15. This sliding connection design allows the limiting plate 16 to be flexibly adjusted to adapt to different usage conditions. A second baffle 17 is fixedly connected to the rear side of the limiting plate 16. When the limiting plate 16 slides, the second baffle 17 moves accordingly, always cooperating with the baffle 15 to form a closed protective area. The top ends of multiple limiting strips 5 are fixedly connected to the bottom ends of the two connecting shafts 2 on both sides. The limiting strips 5 fixedly connected to the bottom ends of the connecting shafts 2 can evenly distribute the force on the connecting shafts 2 to the protective plates 3.

[0033] Multiple fixed discs 9 are fixedly connected on their adjacent sides to the opposite sides of two protective plates 3. The fixed discs 9, fixed to the protective plates 3, reduce shaking during transmission through the support of the protective plates 3. Simultaneously, the protective plates 3 shield the transmission components, preventing operators from contacting rotating parts and improving the safety of the device. Multiple limiting strips 5 are externally slidably connected to the inner walls of the two protective plates 3. The inner walls of the protective plates 3 are provided with grooves or guide rails adapted to the limiting strips 5. The limiting strips 5 are slidably connected to the inner walls of the protective plates 3 via sliders 6. The bottom inner walls of the two protective plates 3 are fixedly connected to the outer sides of the two connecting shafts 2. This fixed connection between the bottom inner walls of the protective plates 3 and the connecting shafts 2 improves the stability of the device's operation. Limiting grooves are formed at the top of the two protective plates 3. These grooves constrain the limiting posts 14, ensuring accurate docking and installation of the battery compartment 12 with the protective plates 3. Multiple limiting posts 14 are fixedly connected to the inner top of the two protective plates 3 on opposite sides. The limiting posts 14 are inserted into the limiting grooves of the protective plates 3, which protects the battery compartment 12 and enhances the safety of the overall structure of the device.

[0034] Multiple limiting posts 14 are externally slidably connected to the inner wall of the bottom end of the battery compartment 12. The inner wall of the bottom end of the battery compartment 12 is provided with sliding holes or guide rails adapted to the limiting posts 14. The limiting posts 14 are slidably connected to the battery compartment 12 through linear bearings or sliding bushings. The rear side of the baffle 2 17 is fixedly connected to the front side of the other of the two protective plates 3. The baffle 2 17 is fixed to the front side of the other protective plate 3 by bolts or buckles, forming a left-right symmetrical protective structure with the baffle 1 15. The exterior of the baffle 2 17 is slidably connected to the inner wall of the baffle 15. The inner wall of the baffle 15 is provided with a vertical sliding groove adapted to the baffle 2 17. The baffle 2 17 is slidably connected to the baffle 15 through a slider 6. The exterior of the pressure plate 20 is fixedly connected to the interior of the power column 18. The pressure plate 20 is fixed to the inner wall of the power column 18 by welding or bolts, forming a partition of the internal space of the power column 18. The edge of the pressure plate 20 fits tightly against the inner wall of the power column 18 to ensure that it does not loosen when the power column 18 rotates.

[0035] The rear sides of the two limiting blocks 21 are slidably connected to the front sides of the two limiting posts 23. The sliding connection design allows the limiting blocks 21 to move synchronously with the rotating cutter head 24, ensuring reliable circumferential limiting of the rotating cutter head 24 at any position. The exterior of the two limiting blocks 21 is slidably connected to the interior of the power column 18. The sliding connection allows the limiting blocks 21 to tightly adhere to the rotating cutter head 24 under the pressure of the pressure plate 20 while rotating with the power column 18, ensuring the stability of power transmission. The exterior of the two limiting posts 23 is fixedly connected to the inner wall of the power column 18. The limiting posts 23 fixed to the inner wall of the power column 18 can convert the extension and retraction motion of the retraction column 22 into the linear movement of the rotating cutter head 24, while providing reliable circumferential support and improving the stability of the pruning operation when the rotating cutter head 24 rotates. The bottom end of the rotating cutter head 24 is fixedly connected to the inside of the power column 18. This fixed connection enhances the support strength of the rotating cutter head 24, allowing it to withstand greater shearing force when pruning thicker branches. The rear side of the rotating cutter head 24 is slidably connected to the front side of the fixed cutter head 27. When the rotating cutter head 24 rotates, its rear side slides along the front side of the fixed cutter head 27, forming a shearing pair. The two work together to prune the branches.

[0036] Working principle: After the device is used, the operator pulls the control bar 7, which moves the slider 6 and the limit bar 5. The limit bar 5 pulls the retraction column 4 to compress the spring 8, which in turn moves the protective plate 3 to be fixed with the connecting shaft 2 as the support point, thus protecting the power compartment 1. When needed, the control bar 7 is released, the spring 8 returns to its original position and pushes the limit bar 5, causing the protective plate 3 to detach from the power compartment 1 and move to the outside of the battery compartment 12. Then, the protective plate 3 is rotated so that its limit groove engages with the limit column 14, thus completing the protection of the battery compartment 12. This achieves targeted protection for the power compartment 1 and the battery compartment 12 under different usage conditions, which not only reduces the risk of damage to key components but also extends the service life of the device and improves the safety and convenience of use.

[0037] When the rotating cutter head 24 needs to be replaced, the operator rotates the nut 19. The nut 19 rises along the threaded inner wall of the power column 18, driving the pressure plate 20, which is rotatably connected to it, and the limiting block 21 fixed at the bottom of the pressure plate 20 to rise synchronously. This causes the limiting block 21 to disengage from the limiting post 23. The limiting post 23, which has lost its limiting position, resets under the elastic action of the spring 25, causing the rotating cutter head 24 to separate from the power column 18. This allows for easy disassembly of the rotating cutter head 24. During installation, the new rotating cutter head 24 is aligned with the power column 18 and pressed down. The limiting post 23 compresses the spring 3, causing the rotating cutter head 24 to reset. The nut 19 is rotated in the opposite direction, causing the pressure plate 20 and the limiting block 21 to descend and re-lock the limiting post 23, thus achieving the effect of quick disassembly and installation of the rotating cutter head 24 without the need for additional tools. This significantly improves the efficiency of cutter head replacement, reduces maintenance costs, and enhances the applicability and practicality of the pruning device.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
