Description

Technical Field

[0001] This utility model relates to the technical field of areca nut plantation, and more specifically, it relates to a tool for harvesting areca nuts. Background Technology

[0002] In areca nut plantations, harvesting areca nuts is a laborious and time-intensive task. Existing technology usually relies on manual harvesting, which is not only inefficient, but also prone to uneven or missed harvesting. Especially when dealing with areca nut trees of different heights, manual harvesting often requires frequent climbing up and down ladders, increasing labor intensity and time consumption. At the same time, since traditional tools do not have automation functions, workers need to spend a lot of time adjusting the harvesting tools at each harvesting point, which directly affects the efficiency and safety of the harvesting work.

[0003] In addition, the height of areca trees varies, and existing tools have certain difficulties in adjusting the height and stability. Especially when facing tall areca trees, traditional tools often cannot be quickly adjusted to the appropriate height, which makes it very inconvenient or even dangerous for workers to harvest at height. The height adjustment and fixing process of the tools is complicated and cannot meet the needs of quick and accurate adjustment, thus affecting the overall harvesting efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a tool for harvesting areca nuts to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: A harvesting tool for areca nuts, comprising a support sleeve, on which a lifting mechanism is provided. The lifting mechanism includes an adjusting rod, a movable groove, a fixed sleeve, a clearance groove, a rotating plate, a rotating rod, a threaded sleeve, and an abutment sleeve. The adjusting rod slides within the support sleeve. Multiple sets of movable grooves are distributed on the outer wall of the adjusting rod. The fixed sleeve is installed at the top of the support sleeve. Multiple sets of clearance grooves are distributed on the outer side of the fixed sleeve. Multiple sets of rotating plates are distributed within multiple clearance grooves. The rotating rod is installed on both sides of the multiple sets of rotating plates and rotatably connected to the fixed sleeve. The threaded sleeve is threadedly connected to the outer wall of the fixed sleeve. The abutment sleeve is fixed at the bottom end of the threaded sleeve. A shearing mechanism is provided at the top of the adjusting rod. The shearing mechanism includes a mounting frame, a linkage gear, a slider, a rack, a cutter, and a drive mechanism. The mounting frame is fixed at the top of the adjusting rod. Two sets of linkage gears rotate within the mounting frame. Two sets of sliders slide within the mounting frame. The rack is installed on the bottom surface of the two sets of sliders and meshes with the linkage gears respectively. The cutter is installed on the top surface of the two sets of sliders.

[0008] The present invention is further configured such that the driving mechanism includes a micro motor, a driving gear and a transmission gear. The micro motor is fixed on the top surface of the mounting frame, the driving gear rotates within the mounting frame and is connected to the output end of the micro motor, the driving gear meshes with a set of linkage gears, and the transmission gear is rotatably mounted within the mounting frame and meshes with the driving gear and the linkage gear respectively.

[0009] This invention is further configured such that a connecting frame is installed on the outer wall of the adjusting rod, and a collection bag is connected to the outer wall of the connecting frame. This design allows the areca nuts to directly enter the collection bag, preventing them from falling out, reducing manual handling, and improving efficiency.

[0010] This invention is further configured such that the top ends of the multiple sets of rotating rods are arc-shaped and abut against the inner wall of the movable groove. The arc design reduces friction, ensures smooth rotation, and improves the durability and stability of the device.

[0011] This invention is further configured such that each of the multiple sets of movable slots is provided with an arc-shaped annular groove. The arc-shaped groove, in conjunction with the top of the rotating rod, reduces friction, allowing the adjusting rod to slide smoothly and ensuring precise adjustment.

[0012] The present invention is further configured such that a push spring is connected to the outer wall of the fixing sleeve, and a push sleeve is connected to the bottom end of the push spring. The push spring and the push sleeve provide elasticity, ensuring that the fixing sleeve can be smoothly adjusted and securely locked during adjustment, preventing loosening.

[0013] This invention further includes an anti-slip strip on the outer wall of the threaded sleeve, with multiple sets of anti-slip strips distributed on the outer wall of the threaded sleeve. The anti-slip strips increase friction, ensure stable rotation, and improve operational convenience and safety.

[0014] This invention is further configured such that the mounting bracket is provided with guide strips, and multiple sets of sliders are provided with guide grooves, all of which are slidably connected to the guide strips. The guide strips and guide grooves ensure smooth slider movement, improve cutting accuracy, and increase work efficiency.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a tool for harvesting areca nuts, which has the following characteristics:

[0017] Beneficial effects:

[0018] 1. The lifting mechanism slides within the support sleeve via an adjusting rod, allowing the harvesting tool to adapt to areca palm trees of different heights. When the adjusting rod moves to the appropriate height, the movable groove engages with the fixed sleeve for limiting. After rotating the threaded sleeve, the abutment sleeve pushes the rotating plate to rotate along the rotating rod, causing the outer wall of the rotating plate to abut against the fixed sleeve and press against the movable groove, thereby fixing the height of the adjusting rod. This mechanism allows the tool to quickly adapt to different working heights, improving harvesting efficiency and reducing labor intensity.

[0019] 2. The shearing mechanism is fixed to the top of the adjusting rod by the mounting bracket. The linkage gears mesh with the rack at the bottom of the slider. The cutter is installed on the slider. When the motor starts, the drive gear drives the linkage gear to rotate synchronously, so that the slider slides along the guide bar, thereby driving the cutter to move inward and complete the shearing operation. This mechanism can quickly complete the shearing of areca nuts, while ensuring uniform shearing force, improving the accuracy and efficiency of harvesting, and avoiding the instability of manual operation.

[0020] 3. The quick fixing of the lifting mechanism is achieved through the threaded connection between the threaded sleeve and the fixed sleeve. When the threaded sleeve is tightened, the abutment sleeve applies pressure to the rotating plate, making it fit tightly against the outer wall of the fixed sleeve, and the stability of the adjusting rod is ensured by the limiting of the rotating rod. When the height needs to be adjusted again, the threaded sleeve is rotated to release the limiting of the rotating plate. At the same time, the push spring pushes the push sleeve to act on the rotating plate, making it rotate along the rotating rod and enter the relief groove, thereby releasing the limiting of the movable groove, so that the adjusting rod can slide freely and be adjusted to a new height. This mechanism realizes the quick unlocking and locking of the lifting function, improving the convenience of the harvesting process and the continuity of operation. Attached Figure Description

[0030] Please see Figures 1-5 A tool for harvesting areca nuts includes a support sleeve 1 with a lifting mechanism. The lifting mechanism includes an adjusting rod 2, a movable groove 3, a fixed sleeve 4, a clearance groove 5, a rotating plate 6, a rotating rod 7, a threaded sleeve 8, and an abutment sleeve 9. The adjusting rod 2 slides inside the support sleeve 1. Multiple sets of movable grooves 3 are distributed on the outer wall of the adjusting rod 2. The fixed sleeve 4 is installed at the top of the support sleeve 1. Multiple sets of clearance grooves 5 are distributed on the outer side of the fixed sleeve 4. Multiple sets of rotating plates 6 are distributed within the clearance grooves 5. The rotating rod 7 is installed on both sides of the multiple sets of rotating plates 6 and is rotatably connected to the fixed sleeve 4. The threaded sleeve 8 is threadedly connected to the outer wall of the fixed sleeve 4, and the abutment sleeve 9 is fixed to the bottom end of the threaded sleeve 8. The top end of the adjusting rod 2 is provided with a shearing mechanism, which includes a mounting frame 10, a linkage gear 11, a slider 12, a rack 13, a cutter 14, and a drive mechanism. The mounting frame 10 is fixed to the top end of the adjusting rod 2. The linkage gear 11 has two sets of rotating parts that rotate within the mounting frame 10. The slider 12 has two sets of sliding parts that slide within the mounting frame 10. The rack 13 is installed on the bottom surface of the two sets of sliders 12 and meshes with the linkage gear 11 respectively. The cutter 14 is installed on the top surface of the two sets of sliders 12.

[0031] The drive mechanism includes a micro motor 15, a drive gear 16, and a transmission gear 17. The micro motor 15 is fixed on the top surface of the mounting frame 10. The drive gear 16 rotates within the mounting frame 10 and is connected to the output end of the micro motor 15. The drive gear 16 meshes with a set of linkage gears 11. The transmission gear 17 is rotatably mounted within the mounting frame 10 and meshes with the drive gear 16 and the linkage gears 11 respectively.

[0032] A connecting frame 18 is installed on the outer wall of the adjusting rod 2, and a collection bag 19 is connected to the outer wall of the connecting frame 18. This design allows the areca nuts to go directly into the collection bag, preventing them from falling and improving efficiency.

[0033] The tops of the multiple rotating rods 7 are rounded and abut against the inner wall of the movable groove 3. The rounded design reduces friction, ensures smooth rotation, and improves stability.

[0034] Each of the multiple movable grooves 3 is equipped with an arc-shaped annular groove. The arc-shaped groove design allows the adjusting rod 2 to slide smoothly, ensuring precise adjustment.

[0035] A push spring 20 is connected to the outer wall of the fixed sleeve 4, and a push sleeve 21 is connected to the bottom end of the push spring 20. The push spring and the push sleeve ensure smooth movement and stable locking of the fixed sleeve.

[0036] The outer wall of the threaded sleeve 8 is provided with anti-slip strips 22, and multiple sets of anti-slip strips 22 are distributed on the outer wall of the threaded sleeve 8. The anti-slip strips increase friction and ensure stable rotation.

[0037] The mounting bracket 10 is equipped with guide bars 23, and multiple sets of sliders 12 are provided with guide grooves 24, which are slidably connected to the guide bars 23. The guide bars 23 and guide grooves 24 ensure smooth sliding of the sliders 12 and improve the accuracy of the cutter 14.

[0038] In this embodiment, when it is necessary to harvest areca nuts, the height of the adjusting rod 2 is first adjusted. When the adjusting rod 2 slides to a suitable positioning height within the support sleeve 1, it is positioned by multiple sets of movable grooves 3. The rotating threaded sleeve 8 is threadedly connected to the outer wall of the fixed sleeve 4, thereby driving the abutting sleeve 9 to push multiple sets of rotating plates 6 to rotate along the rotating rod 7 within the relief groove 5. When the outer walls of the multiple rotating plates abut against the inner wall of the fixed sleeve 4, their top ends abut against the outer wall of the movable groove 3. Tightening the threaded sleeve 8 makes the abutting sleeve 9 press against the outer wall of the rotating plate 6 for securing. Then, the cutter 14 is aligned with the areca nut branch, and the motor is started to drive the drive gear 16 to rotate. The drive gear 16 meshes with the transmission gear 17 and a set of linkage gears 11 respectively. At the same time, the transmission gear 17 meshes with another set of linkage gears 11, so that the two sets of linkage gears 11 mesh with the transmission gear ring respectively. The gear ring drives the slider 12 to slide along the guide bar 23 through the guide groove 24, thereby driving the cutter 14 to slide inward at the same time to cut the areca nut branch. Then the areca nut falls into the collection bag 19, and the areca nut can be harvested.

[0039] More specifically, when the height needs to be adjusted again, the rotating threaded sleeve 8 is threadedly connected to the fixed sleeve 4, thereby causing the abutment sleeve 9 to release its contact with the multiple sets of rotating plates 6. Then, the push spring 20 pushes the plate 6 to slide along the fixed sleeve 4, and the push sleeve 21 pushes the multiple sets of rotating plates 6 to rotate along the rotating rod 7 into the relief groove 5, releasing its contact with the movable groove 3. Then, the adjusting rod 2 can slide along the support sleeve 1 to adjust the height again.

[0040] In summary, when using or operating the entire equipment: First, adjust the height of the adjusting rod 2. When the adjusting rod 2 slides within the support sleeve 1 to the appropriate positioning height, it is positioned via multiple sets of movable grooves 3. The rotating threaded sleeve 8 is threadedly connected to the outer wall of the fixed sleeve 4, thereby driving the abutting sleeve 9 to push multiple sets of rotating plates 6 to rotate along the rotating rod 7 within the clearance groove 5. When the outer walls of the multiple rotating plates abut against the inner wall of the fixed sleeve 4, their tops abut against the outer wall of the movable groove 3. Tightening the threaded sleeve 8 ensures that the abutting sleeve 9 is pressed tightly against the outer wall of the rotating plate 6. After securing the branch, align the cutter 14 with the areca branch and start the motor to drive the drive gear 16 to rotate. The drive gear 16 meshes with the transmission gear 17 and a set of linkage gears 11. At the same time, the transmission gear 17 meshes with another set of linkage gears 11, so that the two sets of linkage gears 11 mesh with the transmission gear rings. The gear rings drive the slider 12 to slide along the guide bar 23 through the guide groove 24, thereby driving the cutter 14 to slide inward to cut the areca branch. The areca nuts then fall into the collection bag 19, and the areca nuts can be harvested.

[0041] When the height needs to be adjusted again, the rotating threaded sleeve 8 is threadedly connected to the fixed sleeve 4, thereby causing the abutment sleeve 9 to release its contact with the multiple sets of rotating plates 6. Then, the push spring 20 pushes the plate 6 to slide along the fixed sleeve 4, and the push sleeve 21 pushes the multiple sets of rotating plates 6 to rotate along the rotating rod 7 into the relief groove 5, releasing its contact with the movable groove 3. Then, the adjusting rod 2 can slide along the support sleeve 1 to adjust the height again.

[0042] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
