Description

Technical Field

[0001] This invention relates to the field of fruit harvesting machine technology, specifically a dual-purpose lithium-ion portable fruit harvester. Background Technology

[0002] Portable harvesting equipment has been widely used in various orchard settings due to its ability to effectively reduce the labor intensity of operators and improve harvesting efficiency. Currently, most portable harvesters on the market use a single telescopic structure combined with a power unit to achieve the harvesting function. However, in actual use, due to structural design limitations, there are still many shortcomings that need to be addressed, which seriously affect the convenience and efficiency of harvesting operations and make it difficult to meet the needs of harvesting in multiple scenarios and for extended periods.

[0003] Among these, two drawbacks stand out most prominently: First, the telescopic adjustment structure is unreasonable. Existing equipment often uses a simple sleeve connection and bolt fastening method for the telescopic sleeve, which is cumbersome to adjust and has poor fastening effect, easily leading to loosening and wobbling of the telescopic sleeve. Some equipment even lacks an effective limiting structure, causing the inner tube to easily detach from the outer tube, which not only affects harvesting efficiency but also poses certain safety hazards. At the same time, it cannot accurately adapt to the harvesting needs of fruit trees of different heights. Second, it is difficult to balance battery life and portability. Existing portable harvesters mostly use a single handheld lithium battery for power, which has a limited battery life. Operators are prone to battery anxiety during long harvesting operations. Using a large-capacity power supply would increase the overall weight of the equipment, making it bulky and inconvenient to carry. Moreover, most equipment lacks a user-friendly carrying design, requiring manual operation throughout the process, which is labor-intensive, does not meet ergonomic requirements, and easily causes operator fatigue.

[0004] The shortcomings of the existing equipment mentioned above restrict the practical application effect of portable harvesters and cannot fully meet the orchard's needs for efficient, convenient and safe harvesting. Therefore, developing a portable harvester that can solve the above pain points and take into account the ease of adjustment, battery stability and user-friendly operation has become an urgent need in the industry.

[0018] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0019] Please see Figure 1 , Figure 2 and Figure 3 A dual-purpose lithium-ion portable fruit picker includes a handle 1, with a telescopic rod 2 fixedly connected to the front end of the handle 1. The telescopic rod 2 can be flexibly adjusted in length according to the picking height, solving the problem of traditional fruit pickers having a fixed length and being unable to adapt to fruit trees of different heights. A fastening component 6 is provided at the telescopic adjustment point of the telescopic rod 2 to achieve a stable lock after adjustment, preventing accidental extension or retraction during picking and improving the stability of the equipment. A drive component 3 is fixedly connected to the other end of the telescopic rod 2, providing stable power for the picking action. A reciprocating transmission rod 4 is provided on the drive component 3 to transmit the power of the drive component 3. A hook 5 is fixedly connected to the transmission rod 4, which is used to engage branches and complete the shaking picking action. The various components work together to initially achieve the portability of the equipment and the continuity of the picking action, taking into account both ease of operation and picking efficiency. The telescopic sleeve 2 includes an outer tube 21 and an inner tube 22. The outer tube 21 serves as the telescopic base and provides sliding support for the inner tube 22. The inner tube 22 can flexibly extend and retract within the outer tube 21 to adjust the overall length. A fastener 61 is fixed on the outer tube 21. The fastener 61 is used to install and fix other components of the fastening assembly 6 to prevent the fastening assembly 6 from falling off. An adjusting member 62 is provided at the left end of the outer tube 21. The adjusting member 62 is sleeved on the inner tube 22. Through cooperation with the pressure member 66, the inner tube 22 is fastened to prevent it from loosening during harvesting. The design of the cooperation between the outer tube 21 and the inner tube 22 not only ensures the flexibility of telescopic movement but also improves the structural stability through the fastening effect of the adjusting member 62, solving the problems of loosening and shaking in traditional telescopic structures. The drive assembly 3 includes a housing to protect internal components, preventing dust and debris from entering and accidental damage to components, thus extending the equipment's lifespan. A motor 31 is fixed inside the housing. The motor 31 is lithium-ion driven, which is more environmentally friendly, quieter, and more portable than traditional fuel-powered machines, solving the problems of high noise, environmental pollution, and inconvenience associated with traditional harvesters. The output of the motor 31 is connected to the input of a reducer 33. The reducer 33 converts the high-speed rotation of the motor 31 into a low-speed power suitable for harvesting, preventing damage to fruits and branches from excessive speed and improving the stability of power output. The output of the reducer 33... An eccentric wheel 34 is connected to the transmission, and a transmission link 35 is eccentrically connected to the eccentric wheel 34. The transmission link 35 is connected to a reciprocating slider 36, which is fixedly connected to the transmission rod 4. The eccentric wheel 34 replaces the traditional drive link structure, greatly increasing the strength and offsetting some of the unwanted vibrations, making the operation more reasonable. It overcomes the problems of insufficient strength, unreasonable force distribution, and obvious vibration of the traditional drive link. The coordinated operation of the motor 31, reducer 33, eccentric wheel 34, transmission link 35, and reciprocating slider 36 converts the rotational motion of the motor 31 into the reciprocating linear motion of the transmission rod 4, providing stable and efficient power transmission for the picking action.

[0020] Please see Figure 1The handle 1 is equipped with a drive button 12 for controlling the start and stop of the motor 31. The drive button 12 is installed in a convenient operating position on the handle 1, allowing the operator to control the start and stop of the motor 31 at any time without adjusting the grip posture, thus improving the ease of operation and reducing the difficulty of operation. A counterweight 13 is fixed on the handle 1, and an anti-slip sleeve 11 is provided at one end of the outer tube 21 near the handle 1. The anti-slip sleeve 11 can increase the friction between the hand and the equipment, prevent the equipment from accidentally slipping during the harvesting process, improve the safety of use, and enhance the grip comfort, reducing fatigue from holding it for a long time. A shoulder strap 14 is fixed on the handle 1, and the other end of the shoulder strap 14 is connected to the outer tube 21. The operator can carry the equipment on their shoulder through the shoulder strap 14, reducing the burden on the hand and overcoming the problem of traditional harvesters being held by hand the whole time and having high labor intensity. It is suitable for long-term harvesting operations and further improves the portability of the equipment.

[0021] Please see Figure 2 and Figure 4 The fastener 61 has two symmetrically arranged through slots 611. Fastening ears 612, which are fixedly connected to the fastener 61, are respectively provided on the upper and lower sides of the through slots 611. Two adjacent fastening ears 612 are connected by bolts. Tightening the bolts securely fixes the fastener 61 to the outer tube 21, preventing the fastener 61 from detaching from the outer tube 21. This solves the problem of traditional adjustment components being unstable and prone to falling off, improving the overall stability of the fastening component 6. Pressing blocks 63 are rotatably connected to the upper and lower sides of the fastener 61. The pressing blocks 63 can rotate flexibly, allowing operators to press with one or both hands, achieving quick unlocking of the inner tube 22. Compared to the traditional manual unlocking method, this saves adjustment time and improves harvesting efficiency.

[0022] Please see Figure 2 and Figure 4The left end of the fastener 61 is fixedly connected to a pressure-bearing component 66. Multiple grooves are formed along the circumference of the pressure-bearing component 66. The groove design enhances the contraction performance of the pressure-bearing component 66, allowing the adjusting component 62 to tightly wrap around the inner tube 22 after compression, thus improving the clamping effect. The adjusting component 62 is threadedly connected to the pressure-bearing component 66, making it easy for the operator to tighten or loosen the clamp by turning the adjusting component 62. The adjusting component 62 has a conical internal shape with a larger diameter at the end near the handle 1. This conical structure allows the adjusting component 62 to gradually compress the pressure-bearing component 66 when tightened, causing the pressure-bearing component 66 to contract evenly and firmly clamp the inner tube 22, preventing the inner tube 22 from expanding or contracting. This solves the problems of insufficient clamping force and easy loosening of the inner tube 22 in traditional fastening structures. The outer surface of the adjusting component 62... The circumference of the device is provided with anti-slip texture, which increases the friction between the hand and the adjusting part 62, preventing slippage during twisting and improving ease of operation. One end of the pressing block 63 is connected to a limit pin 64, and a spring 65 is provided below the other end of the pressing block 63. The spring 65 provides the reset power for the pressing block 63. Limiting holes 7 are respectively provided on the outer tube 21 and the inner tube 22, and the limiting holes 7 correspond to the limiting pins 64. The cooperation of the spring 65, the pressing block 63, the limiting pins 64 and the limiting holes 7 can realize the limiting and fixing of the inner tube 22, preventing the inner tube 22 from completely detaching from the outer tube 21. This solves the problem of traditional telescopic structures having no effective limiting and the inner tube 22 being easy to fall off. At the same time, the appropriate limiting hole 7 can be selected according to the picking height to achieve precise adjustment of the length of the inner tube 22.

[0023] Please see Figure 1 , Figure 3 and Figure 5 The motor 31 has a protective cover 32 fixedly connected to the housing at its rear end. The protective cover 32 can effectively shield the transmission structure at the rear end of the motor 31, preventing dust and debris from entering the motor 31 and the reducer 33, protecting the internal components from damage, and preventing operators from contacting the rotating parts, thus improving safety and extending the service life of the equipment. The reducer 33 is fixedly connected to the housing of the drive assembly 3, ensuring that the reducer 33 is firmly installed and preventing shaking or displacement during power transmission. The output end of the reducer 33 is connected to the center of the eccentric wheel 34, ensuring that the eccentric wheel 34 rotates smoothly, the power transmission is accurate, and the power loss is reduced. The transmission connecting rod 35 is rotatably connected to the reciprocating slider 36, which can reduce the friction during transmission, making the reciprocating slider 36 move more smoothly, preventing the transmission components from wearing out too quickly, and further extending the service life of the equipment.

[0024] Please see Figure 1 , Figure 3 and Figure 5The reciprocating slider 36 has two pulleys 38 at its upper and lower ends, respectively. The pulleys 38 on the same side are located on the same straight line, and the pulleys 38 on both sides are arranged in parallel. The symmetrical arrangement of the pulleys 38 can ensure that the reciprocating slider 36 moves smoothly along the guide direction and avoids the problems of deviation and jamming during the movement. At the same time, the pulleys 38 convert the sliding friction between the reciprocating slider 36 and the guide rod 37 into rolling friction, which greatly reduces the friction force, reduces power loss, and reduces component wear. This solves the problems of easy wear of components and poor transmission caused by traditional sliding friction, and improves the durability and transmission efficiency of the equipment.

[0025] Please see Figure 1 , Figure 3 and Figure 5 The reciprocating slider 36 has guide rods 37 fixedly connected to the outer casing at its upper and lower ends. These guide rods 37, in conjunction with the pulley 38, guide the slider, ensuring it moves only in a straight line along the guide rods 37, preventing deviation and ensuring precise reciprocating motion of the transmission rod 4. This, in turn, ensures uniform swaying of the hook 5, improving harvesting efficiency. The outer casing contains several linear bearings 39 slidably connected to the transmission rod 4. These bearings reduce friction during the transmission rod 4's movement, making it slide more smoothly, and also provide support to prevent bending. The design solves the problems of traditional transmission rod 4 being unsupported, easily bent, and having uneven movement. The transmission rod 4 is connected to the hook 5, transmitting the reciprocating motion to the hook 5. The hook 5 is U-shaped, and its U-shaped structure can easily attach to branches of different thicknesses, making it suitable for harvesting various fruit trees. This solves the problem of poor adaptability and difficulty in attaching branches with traditional hook 5. A rubber part 51 is fixed to the inner side of the hook 5. The rubber part 51 is soft and can effectively buffer the impact between the hook 5 and the branch when the hook 5 shakes the branch back and forth, protecting the branch from scratches and breakage. This solves the problem of high hardness and easy damage to fruit trees with traditional hook 5, balancing harvesting efficiency and fruit tree protection.

[0026] Please see Figure 3 , Figure 5 and Figure 6The reducer 33 includes two teardrop-shaped protective shells 331. Compared with traditional rectangular gearboxes, the teardrop-shaped protective shells 331 can significantly reduce the internal clearance, making the meshing between the driving gear 333 and the driven gear 332 more compact. This avoids the problem of excessive clearance between the pinion and the gearbox wall and easy lubrication oil being thrown off the pinion in traditional rectangular gearboxes. It facilitates lubrication oil retention, maintains proper lubrication, reduces gear wear, extends the service life of the reducer 33, and improves power transmission efficiency. The driven gear 332 and the driving gear 333 are rotatably connected inside the protective shell 331. The driven gear 332 and the driving gear 333 are drivenly connected to achieve power reduction transmission. The driven gear 332 is drivenly connected to the eccentric wheel 34, and the driving gear 333 is drivenly connected to the output end of the motor 31. The cooperation between the driving gear 333, the driven gear 332, and the teardrop-shaped protective shells 331 ensures the stability and efficiency of power transmission, and solves the problems of poor lubrication and easy wear of components in traditional reducers, thus providing a guarantee for the stable operation of the equipment.

[0027] In summary, the coordinated operation of all components achieves three core effects: First, the telescopic sleeve 2 and the fastening assembly 6 allow for flexible adjustment of the equipment length to accommodate different harvesting heights, ensuring stability and reliability after adjustment and preventing loosening or detachment. Second, the optimized design of each component in the drive assembly 3 enables smooth and efficient power transmission with minimal vibration and convenient operation, while protecting the fruit trees from damage. Third, the user-friendly design of components such as the hand grip 1 and the shoulder strap 14, combined with the portability of lithium batteries, reduces the labor intensity of operators and solves problems such as the head-heavy design, insufficient battery life, and high labor intensity of traditional harvesters. Ultimately, this achieves portable, efficient, safe, and environmentally friendly fruit harvesting, adapting to the needs of long-term, multi-scenario harvesting operations.

[0028] When using this invention: The first step is to check that all parts of the equipment are intact, paying particular attention to whether the rubber part 51 inside the hook 5 is intact and not detached, ensuring that it can effectively protect the branches when shaking them; check that the outer shell and protective cover 32 of the drive component 3 are tightly closed to prevent internal parts from loosening or dust from entering; check that the pressing block 63, limit pin 64, and spring 65 of the fastening component 6 are flexible, and that the threads of the adjusting part 62 are smooth and the anti-slip texture is unworn. At the same time, select the power supply method according to the harvesting time requirements. For short-term harvesting, a handheld lithium battery can be used; for longer-term operation, switch to a backpack lithium battery. Connect the lithium battery correctly to the equipment's power supply interface and confirm a stable power supply to avoid power outages during use.

[0029] The second step involves the operator hanging the shoulder straps 14 over their shoulders, adjusting the length to a comfortable position, and then carrying the main body of the device securely on their shoulders via the shoulder straps 14. Simultaneously, the external backpack lithium battery is carried on the back, ensuring it is firmly secured and the power supply lines are not pulled. Next, the operator holds the anti-slip sleeve 11 near the handle 1 of the outer tube 21. The anti-slip sleeve 11 increases friction between the hand and the device, preventing slippage during handling. The operator adjusts their grip to a comfortable position, ensuring convenient operation when pressing the drive button 12 or adjusting the device length. Based on their own feel, the operator can adjust the weights 13 on the handle 1 as needed to prevent the device from becoming top-heavy and reduce fatigue during prolonged use.

[0030] Third, adjust the length of the telescopic sleeve 2 according to the height of the fruit to be picked: Press the pressing blocks 63 on both sides of the fastener 61 with your fingers. At this time, the spring 65 under the pressing block 63 is compressed. The pressing block 63 drives the limiting pin 64 connected at one end to move out of the corresponding limiting hole 7 of the outer tube 21 and the inner tube 22, releasing the limiting fixation of the inner tube 22. After releasing the limit, use both hands to slowly pull the inner tube 22 out of the outer tube 21. When it is pulled out to near the picking height, slowly release the pressing block 63. Under the action of the deformation restoring force, the spring 65 pushes the pressing block 63 to reset. The pressing block 63 drives the limiting pin 64 to re-insert into the corresponding limiting hole 7, temporarily limiting the inner tube 22 to prevent the inner tube 22 from continuing to slide or completely coming out of the outer tube 21. Then, turn the adjusting part 62 by hand. Since the inside of the adjusting part 62 is conical and the diameter of the end near the handle 1 is larger, the adjusting part 62 will gradually squeeze the inner pressure part 66 during the turning process. The pressure part 66 shrinks along the circumferential groove, firmly clamping the inner tube 22, thereby fixing the length of the telescopic sleeve 2, preventing the inner tube 22 from stretching and shaking during the picking process, and ensuring that the length after adjustment is stable and adapted to the picking height.

[0031] Fourth step: After length adjustment, harvesting begins. The operator holds the device and slowly engages the U-shaped hook 5 connected to the end of the inner tube 22 onto the branch with fruit. Ensure that the rubber part 51 inside the hook 5 fits tightly against the branch. The rubber part 51 is soft and can cushion the impact on the branch during subsequent shaking, preventing scratches and breakage. After secure engagement, press the drive button 12 on the handle 1 with your thumb to start the motor 31. The output of the motor 31 drives the drive wheel 333 inside the reducer 33 to rotate. The drive wheel 333 is connected to the driven wheel 332, causing the driven wheel 332 to rotate synchronously. The driven wheel 332 then drives the eccentric wheel 34 connected to the output to rotate. Because the eccentric wheel 34 is eccentrically connected to the transmission rod 35, and the other end of the transmission rod 35 is rotatably connected to the reciprocating slider 36, and the reciprocating slider 36 is guided and limited by the guide rod 37 and the pulley 38, the rotational motion of the eccentric wheel 34 is converted into the linear reciprocating motion of the reciprocating slider 36 along the guide rod 37. The reciprocating slider 36 drives the connected transmission rod 4 to reciprocate synchronously, and the transmission rod 4 drives the hook 5 to reciprocate and shake the branches. The pulley 38 converts the sliding friction between the reciprocating slider 36 and the guide rod 37 into rolling friction, and the linear bearing 39 reduces the friction force when the transmission rod 4 moves, ensuring that the shaking action is smooth and stable. During the reciprocating shaking process, the fruit falls off due to inertia, realizing fruit harvesting. During the harvesting process, the position of the hook 5 can be adjusted according to the distribution of the fruit. Press the drive button 12 continuously to shake and harvest. Release the drive button 12, and the motor 31 will stop running, pausing the harvesting action. If the harvesting height needs to be adjusted, the telescopic adjustment steps in step three can be repeated to flexibly adjust the length of the equipment.

[0032] Fifth, after harvesting, store the equipment as follows: First, release the drive button 12, turn off the motor 31, disconnect the lithium battery from the power supply of the equipment, and remove the lithium battery for safe storage. Then, loosen the adjusting piece 62 to release the clamping of the pressure piece 66 on the inner tube 22, press the pressing block 63 to move the limiting pin 64 out of the limiting hole 7, and slowly push the inner tube 22 into the outer tube 21 until it is fully retracted and reset. Release the pressing block 63 to allow the limiting pin 64 to be inserted and fixed, completing the reset of the telescopic sleeve 2. Finally, remove the shoulder strap 14, wipe the equipment clean, clean the debris on the hook 5, and check whether any parts are worn or loose. If any abnormalities are found, deal with them promptly. Then, store the equipment, lithium battery, and related accessories properly in a dry and ventilated environment to avoid damage caused by moisture or collisions, making it convenient for the next use.
