[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] Example 1

[0031] like Figures 1 to 8 As shown, a portable eggplant harvester includes a harvesting pole 1;

[0032] The harvesting rod 1 has a first groove 24 and a second groove 23. A rack plate 1 and a rack plate 23 are slidably connected in the first groove 24 and the second groove 23, respectively. The rack plate 1 and the rack plate 23 are arranged opposite to each other, and a gear 4 is meshed on the surface of the rack plate 1 and the gear 4 is rotatably connected in the harvesting rod 1. A harvesting hook 5 is fixedly installed at one end of the rack plate 23, and a slot 6 is opened at one end of the rack plate 23. A cutting blade 7 is engaged in the slot 6.

[0033] The first groove 24 and the second groove 23 inside the picking rod 1 provide a stable sliding track for the rack plate 1 2 and the rack plate 2 3, ensuring the accuracy and smoothness of their sliding. The meshing structure of the rack plate 1 2, the rack plate 2 3 and the gear 4 realizes the efficient transmission of power. The rack plate 2 3 can be driven to move synchronously by driving the rack plate 1 2, so that the picking hook 5 and the cutting blade 7 can work together to complete the picking operation, simplifying the operation process. The picking hook 5 can accurately hook the eggplant stem, while the cutting blade 7 in the slot 6 can quickly cut the eggplant stem. The integrated design improves the continuity and efficiency of picking.

[0034] Furthermore, the cutting edge of the cutting blade 7 is set at an angle, and the cutting blade 7 is made of stainless steel.

[0035] The cutting blade 7 has an angled cutting edge. This special shape design increases the contact area and shearing force with the eggplant stem, making it easier to cut the stem and reducing resistance during cutting. This prevents the eggplant from shaking and falling due to excessive force. At the same time, the cutting blade 7 is made of stainless steel, which has good corrosion resistance and wear resistance, extending the service life of the blade and reducing the frequency and cost of replacing the blade.

[0036] Furthermore, a fixing screw 8 is threaded onto one end of the rack plate 2 3, and the cutting blade 7 is inserted into the slot 6 opened at one end of the rack plate 2 3 and fixed by the fixing screw 8.

[0037] The fixing screw 8 on the rack plate 2 3 provides a firm fixation for the cutting blade 7, ensuring that the blade will not loosen or fall off during the cutting process, thus guaranteeing the safety and stability of the cutting operation. When the cutting blade 7 becomes worn or damaged, simply unscrew the fixing screw 8 to remove the blade from the slot 6 for replacement. The operation is simple and convenient, facilitating later maintenance and upkeep.

[0038] Furthermore, a strip groove 18 is formed on the surface of the picking rod 1, and an operating handle 17 is slidably connected in the strip groove 18. The operating handle 17 is fixedly connected to one end of the rack plate 2.

[0039] The strip groove 18 on the surface of the picking rod 1 provides sliding space for the operating handle 17, allowing the operating handle 17 to slide smoothly along the strip groove 18. The fixed connection between the operating handle 17 and the rack plate 2 allows the user to directly drive the rack plate 2 to move by operating the operating handle 17. The operation method is intuitive and easy to understand, reducing the user's learning cost, and even first-time users can quickly get started.

[0040] Example 2

[0041] Improvements based on Example 1:

[0042] Furthermore, a fixing block 9 is fixedly installed on the outer surface of the end of the picking rod 1 near the picking hook 5, and an auxiliary fixing clip 10 is fixedly installed on one side of the fixing block 9. When picking, the picking hook 5 slides to one side of the auxiliary fixing clip 10 and clamps the stem of the eggplant being picked.

[0043] The fixing block 9 on the picking rod 1 provides a stable installation base for the auxiliary fixing clamp 10, ensuring the positional stability of the auxiliary fixing clamp 10 during the picking process. When picking, the picking hook 5 slides towards the auxiliary fixing clamp 10, and the two work together to firmly clamp the eggplant stem, preventing the eggplant from shifting during the cutting process, improving the picking accuracy, and avoiding the eggplant from falling or being damaged due to shaking.

[0044] Furthermore, a fixed guide block 11 is fixedly installed on the surface of the fixed block 9, and the rack plate 2 3 is slidably connected to the surface of the fixed guide block 11.

[0045] The fixed guide block 11 on the fixed block 9 guides and limits the sliding of the rack plate 2 3, further ensuring the straightness of the rack plate 2 3 when sliding, preventing it from deviating or shaking during the sliding process, ensuring the accuracy of the action of the picking hook 5 and the cutting blade 7, and improving the reliability of the picking operation.

[0046] Furthermore, a fixing rod 19 is slidably connected in the through hole opened on the surface of the operating handle 17. The fixing rod 19 is fixedly installed in the strip groove 18 opened on the surface of the picking rod 1. A return spring 20 is sleeved on the surface of the fixing rod 19. One end of the return spring 20 abuts against one side surface of the operating handle 17, and the other end of the return spring 20 abuts against the strip groove 18 opened on the surface of the picking rod 1.

[0047] The fixing rod 19 on the operating handle 17 restricts the sliding direction of the operating handle 17, allowing it to slide only along the fixing rod 19 within the strip groove 18, thus ensuring operational stability. The return spring 20 on the surface of the fixing rod 19 accumulates elastic potential energy after the operating handle 17 is pushed. When the operating handle 17 is released, the return spring 20 releases this potential energy, causing the operating handle 17 to automatically reset. This, in turn, returns components such as rack plate 2 and rack plate 3 to their initial positions, preparing them for the next harvest. This eliminates the need for manual reset and improves harvesting efficiency.

[0048] Furthermore, the picking hook 5 is provided with an anti-slip clip 13, and both ends of the anti-slip clip 13 are equipped with connecting slide plates 16. A fixed slide rod 14 is slidably connected to the surface of the connecting slide plate 16. A spring 15 is sleeved on the surface of the fixed slide rod 14. The fixed slide rod 14 is fixedly installed in the strip-shaped clearance groove 12 opened in the inner side wall of the picking hook 5. One end of the spring 15 abuts against one side surface of the connecting slide plate 16, and the other end of the spring 15 abuts against the strip-shaped clearance groove 12 opened in the inner side wall of the picking hook 5.

[0049] The anti-slip clip 13 inside the picking hook 5 increases the friction between the clip and the eggplant stem when they come into contact. The cooperation of the connecting slide plate 16, the fixed slide bar 14, and the spring 15 gives the anti-slip clip 13 a certain elastic buffering capacity. When the eggplant stems are of different sizes, the extension and contraction of the spring 15 allows the anti-slip clip 13 to adaptively fit the eggplant stem, ensuring a firm grip. The fixed slide bar 14 is installed in the strip-shaped relief groove 12, providing a stable track for the sliding of the connecting slide plate 16, ensuring the smooth operation of the anti-slip clip 13, and effectively preventing the eggplant stem from slipping off during picking.

[0050] Furthermore, the anti-slip clip 13 has toothed raised particles on the side surface that contacts the eggplant stem.

[0051] The toothed protrusions on the surface of the anti-slip clip 13 further increase the friction between the clip and the eggplant stem. Especially when the eggplant stem surface is relatively smooth or has a small amount of moisture, it can significantly improve the anti-slip effect, ensure that the eggplant stem is firmly clamped, and prevent the eggplant from falling and being damaged due to loose clamping, thus ensuring the quality of harvesting.

[0052] Furthermore, the surface of the picking rod 1 is sequentially fixed with an anti-slip hand grip 22 and a shoulder strap 21.

[0053] The non-slip handle 22 on the surface of the picking pole 1 increases the friction between the user's hand and the picking pole 1, preventing the picking pole 1 from slipping from the hand during picking, thus improving the safety of operation. It also makes the user more comfortable to hold and reduces hand fatigue. The shoulder strap 21 allows the picking pole 1 to be slung diagonally over the user's shoulder, distributing the weight of the picking pole 1 and making it easy to carry. It also reduces the burden on the hand, allowing the user to carry out picking work for a long time without feeling tired, thus improving the comfort and endurance of the operation.

[0054] Working principle: When the user operates the non-slip hand grip 22 of the picking rod 1, first align the picking hook 5 with the stem of the target eggplant, so that the stem is between the picking hook 5 and the auxiliary fixing clip 10. At this time, push the operating handle 17 in the strip groove 18. Since the operating handle 17 is fixedly connected to the rack plate 2, the rack plate 2 will slide along the first slide groove 24, thereby driving the gear 4 meshing with it to rotate. The gear 4 simultaneously drives the rack plate 3 to slide along the second slide groove 23 and the fixing guide block 11, so that the picking hook 5 at the end of the rack plate 3 moves closer to the auxiliary fixing clip 10.

[0055] During the movement of the picking hook 5, the anti-slip clip 13 on its inner side will first contact the eggplant stem. As the picking hook 5 continues to move, the eggplant stem squeezes the anti-slip clip 13, causing the connecting slide plate 16 to compress the spring 15 along the fixed slide rod 14. The spring 15's rebound force makes the anti-slip clip 13 tightly clamp the eggplant stem. The toothed protrusions further enhance the anti-slip effect and prevent the eggplant stem from slipping off. When the picking hook 5 and the auxiliary fixed clip 10 clamp the eggplant stem together, the cutting blade 7 in the slot 6 at the end of the toothed plate 2 3 moves synchronously with the toothed plate 2 3. The inclined cutting blade contacts the eggplant stem and applies shearing force to cut the eggplant stem, completing the picking action.

[0056] After the operating handle 17 is released, the return spring 20, which is sleeved on the surface of the fixed rod 19, releases its elastic potential energy and pushes the operating handle 17 to return to its original position. Through the rack plate 1 2 and the gear 4, the rack plate 2 3 slides in the opposite direction, so that the picking hook 5 and the cutting blade 7 return to their initial positions for the next picking. Throughout the process, the shoulder strap 21 can help fix the picking rod 1 and reduce the burden on the hand. The stainless steel cutting blade 7 is securely installed by the fixing screw 8 to ensure the reliability of the cutting process.
