[0015] Compared with the prior art, this utility model provides an adjustable-height walnut harvesting aid tool, which has the following beneficial effects:

[0016] 1. The harvesting pole features a main grip at its base, designed with a main grip component, hand sleeve, mounting sleeve, support plate, mounting holes, grooves, fixing holes, telescopic rod, sliding groove, and pins. This provides a comfortable and stable grip, facilitating control of the tool's direction. The hand sleeve at the bottom of the outer rod further enhances grip convenience. Different operators can choose to grip either the main grip component or the hand sleeve based on their habits and needs, improving the tool's flexibility and adaptability. The support plates arranged in an array inside the outer rod strengthen its structure, preventing deformation under external forces. The support plates connect to the mounting holes... The fixing holes in the grooves at the top of the handheld sleeve and the bottom of the mounting sleeve are bolted together. This connection method not only makes the connection between the outer rod, the handheld sleeve, and the mounting sleeve more stable and reliable, but also makes disassembly and installation relatively simple when maintenance or replacement of parts is required, which is conducive to the maintenance and upkeep of the tool. The inner rod has a telescopic rod in the middle, and the upper and lower sides are slidably connected to the slide groove through pins, so that the length of the inner rod can be flexibly adjusted. This design allows the harvesting pole to be easily adjusted according to the actual harvesting height requirements without the need for additional climbing equipment, which greatly improves harvesting efficiency, expands the scope of tool use, and can adapt to walnut harvesting in different growing environments.

[0017] 2. Through the design of the outer cutter head, support frame, inner cutter head, meshing gears, drive motor, transmission gears, and branch slots, the outer cutter head is fixed to the mounting sleeve at the top of the outer rod via the support frame. This structure ensures the stability of the outer cutter head installation. A stable installation prevents the outer cutter head from shaking or loosening during harvesting, making the cutting action more precise, increasing the success rate of cutting branches, extending the service life of the outer cutter head, and enhancing the safety of the entire harvesting tool during operation. The inner cutter head at the top of the inner rod works in conjunction with the outer cutter head to form a cutting structure. Working together, they effectively cut walnut branches, improving harvesting efficiency. The integrated design of the inner cutter head and inner rod ensures direct and stable power transmission during the cutting process, contributing to efficient and reliable cutting operations. The meshing gear at the bottom of the inner rod engages with the transmission gear at the top of the drive motor inside the main grip. The drive motor drives the inner and outer rods to rotate relative to each other. This ingenious transmission structure design ensures stable and efficient power transmission. Operators can easily achieve relative rotation between the inner and outer cutter discs by controlling the drive motor, thus completing the branch cutting. This greatly reduces labor intensity and improves the automation of harvesting operations. The branch slots arranged in the array inside the outer and inner cutter discs can better hold the walnut branches during harvesting. The branch slots can position and fix the branches, preventing them from sliding or shifting during cutting, making the cutting position more accurate and ensuring the cutting effect. At the same time, it also helps to improve the quality and efficiency of harvesting and reduce operational errors and tool damage caused by branch shaking. Attached Figure Description

[0033] A control button 4 is located on the outer side of the main gripper 3. The outer cutter head 2 and the inner cutter head 13 are made of tungsten steel alloy.

[0034] In this embodiment, the specific implementation steps of an adjustable-height walnut harvesting auxiliary tool are as follows: The support plate 6 is confirmed to be securely connected to the handheld sleeve 10 and the fixing holes 11 on the mounting sleeve 9 via the mounting hole 7; the pin 20 on the telescopic rod 15 is installed in the slide groove 16; the outer cutter disc 2 is firmly connected to the support frame 8 and the mounting sleeve 9; the inner cutter disc 13 is stably installed on the top of the inner rod 14; the meshing gear 17 and the transmission gear 19 mesh normally; the control button 4 functions normally; the outer cutter disc 2 and the inner cutter disc 13 are checked for damage; the tungsten carbide alloy blades are ensured to function normally; the height of the harvesting rod is adjusted according to the height of the branch where the walnuts to be harvested are located; during operation, the pin 20 is positioned in the slide groove 16 by pulling or pushing the telescopic rod 15. The inner rod 14 extends inward, thus changing its length and adjusting the height of the entire harvesting rod body 1. After adjusting the harvesting rod to a suitable height, the telescopic rod 15 is fixed and stable to prevent changes in height during harvesting. The operator holds the main grip 3 and aligns the outer blade 2 and inner blade 13 at the top of the harvesting rod with the walnut branch. The branch is secured by the branch slot 21, positioning it between the outer blade 2 and inner blade 13. The operator presses the control button 4 on the outside of the main grip 3 to start the drive motor 18. The drive gear 19 at the top of the drive motor 18 drives the meshing gear 17 at the bottom of the inner rod 14, causing the inner rod 14 and outer rod 5 to rotate relative to each other. The outer blade 2 and inner blade 13 rotate relative to each other, thereby cutting the walnut branch and harvesting the walnuts.

[0035] like Figure 1-3 As shown, a main gripper 3 is provided at the bottom of the main body 1 of the harvesting pole, a hand sleeve 10 is provided at the bottom of the outer pole 5, an installation sleeve 9 is provided at the top of the main body 1 of the harvesting pole, a support plate 6 is arranged in an array inside the outer pole 5, and mounting holes 7 are provided on the upper and lower sides of the support plate 6, respectively. A groove 12 is provided at the top of the hand sleeve 10 and the bottom of the installation sleeve 9, and a fixing hole 11 is provided inside the groove 12. The support plate 6 is nested and connected to the groove 12 at both ends. The support plate 6 is bolted to the fixing hole 11 through the mounting hole 7. A telescopic rod 15 is provided in the middle of the inner pole 14, and sliding grooves 16 are provided on the upper and lower sides of the inner pole 14, respectively. Pins 20 are provided on the upper and lower sides of the telescopic rod 15, and the telescopic rod 15 is slidably connected to the sliding groove 16 through the pins 20.

[0036] Preferably, the main grip 3 is provided at the bottom of the main body 1 of the harvesting pole, which is convenient for the operator to hold and provides a comfortable and stable grip experience, making it easy to control the operation direction of the entire harvesting tool. The hand sleeve 10 at the bottom of the outer pole 5 further enhances the convenience of gripping. Different operators can choose to hold the main grip 3 or the hand sleeve 10 according to their own habits and needs, which improves the flexibility and adaptability of the tool. The support plates 6 arranged in an array inside the outer pole 5 play a role in strengthening the structural strength of the outer pole 5, making it less prone to deformation when subjected to external forces. The support plates 6 are fixed to the top of the hand sleeve 10 and the bottom groove 12 of the mounting sleeve 9 through the mounting holes 7. The 11 bolt connection not only makes the connection between the outer rod 5, the hand sleeve 10 and the installation sleeve 9 more stable and reliable, but also makes disassembly and installation relatively simple when maintenance or replacement of parts is required, which is conducive to the maintenance and upkeep of the tool. The inner rod 14 has a telescopic rod 15 in the middle inside, and the upper and lower sides are slidably connected to the slide groove 16 through the pins 20, so that the length of the inner rod 14 can be flexibly adjusted. This design allows the picking pole to be easily adjusted according to the actual picking height requirements without the need for additional climbing equipment, which greatly improves the picking efficiency, expands the scope of use of the tool, and can adapt to the picking of walnuts in different growing environments.

[0037] like Figure 1-4 As shown, an outer cutter disc 2 is provided at the top of the outer rod 5. The outer cutter disc 2 and the mounting sleeve 9 are fixed together by a support frame 8. An inner cutter disc 13 is provided at the top of the inner rod 14. A meshing gear 17 is provided at the bottom of the inner rod 14. A drive motor 18 is provided inside the main gripper 3. A drive gear 19 is provided at the top of the drive motor 18. The inner rod 14 is driven by the drive motor 18 to rotate relative to the outer rod 5. Branch slots 21 are arranged in an array inside the outer cutter disc 2 and the inner cutter disc 13.

[0038] Preferably, the outer blade disc 2 and the mounting sleeve 9 are fixed to the top of the outer rod 5 via a support frame 8. This structure ensures the stability of the outer blade disc 2 installation. A stable installation ensures that the outer blade disc 2 will not shake or loosen during harvesting, making the cutting action more precise, increasing the success rate of cutting branches, extending the service life of the outer blade disc 2, and also enhancing the safety of the entire harvesting tool during operation. The inner blade disc 13 at the top of the inner rod 14 cooperates with the outer blade disc 2 to form a cutting structure. Working together, they can effectively cut walnut branches, improving harvesting efficiency. The integrated design of the inner blade disc 13 and the inner rod 14 ensures direct and stable power transmission during the cutting process, contributing to efficient and reliable cutting operations. The meshing gear 17 at the bottom of the inner rod 14 engages with the main gripper 3. The transmission gear 19 on the top of the transmission motor 18 engages with the transmission motor 18 to drive the inner rod 14 and the outer rod 5 to rotate relative to each other. This transmission structure is ingeniously designed, and the power transmission is stable and efficient. The operator only needs to control the transmission motor 18 to easily achieve the relative rotation of the inner cutter disc 13 and the outer cutter disc 2, thereby completing the branch cutting. This greatly reduces the labor intensity and improves the automation of the harvesting operation. The branch slots 21 arranged in the array inside the outer cutter disc 2 and the inner cutter disc 13 can better hold the walnut branches during the harvesting process. The branch slots 21 can position and fix the branches, prevent the branches from sliding or shifting during the cutting process, make the cutting position more accurate, ensure the cutting effect, and at the same time help improve the quality and efficiency of harvesting, and reduce operational errors and tool damage caused by branch shaking.

[0039] like Figure 1-4 As shown, a control button 4 is provided on the outer side of the main gripper 3, and the outer cutter head 2 and the inner cutter head 13 are made of tungsten steel alloy.

[0040] Optionally, the main grip 3 is the main part where the operator holds the harvesting tool. Placing the control button 4 here greatly facilitates the operator's operation and control of the tool. During actual harvesting operations, the operator can easily reach the control button 4 without deliberately searching for or significantly changing hand movements. This allows for timely activation, deactivation, or adjustment of the operating status of related components such as the transmission motor 18, achieving precise control of the harvesting tool, improving the convenience and efficiency of operation, and thus enhancing the smoothness of the entire harvesting work. The use of tungsten steel alloy for the outer blade 2 and inner blade 13 brings many advantages. Tungsten steel alloy has extremely high hardness and wear resistance, which allows the outer blade 2 and inner blade 13 to maintain a sharp cutting edge and good cutting performance for a long time during frequent cutting of walnut branches, greatly extending the service life of the blades and reducing the frequency of replacement due to blade wear.

[0041] 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.
