Description

Technical Field

[0001] This utility model relates to the field of hazelnut harvesting technology, specifically to a hazelnut harvesting device. Background Technology

[0002] Hazelnuts are a nutritious nut that needs to be harvested after they mature. Currently, hazelnuts are mostly harvested manually. For hazelnuts at lower elevations, people can pick them directly by hand, but for those at higher elevations, ladders and other tools are often needed. This is not only inconvenient to operate but also poses certain safety hazards and has low harvesting efficiency. In addition, it is impossible to fix the hazelnut branches during the harvesting process, which means that the entire branch is picked along with the hazelnut. This will affect the subsequent growth of the hazelnut and increase the workload later. Utility Model Content

[0021] Example 1:

[0022] Please see Figure 1 As shown, this utility model provides a hazelnut harvesting device, including a fixed frame 1. A threaded telescopic rod 2 is installed inside the fixed frame 1. A drive screw 3 is threaded inside the threaded telescopic rod 2. The lower end of the drive screw 3 extends to the outside of the fixed frame 1 and is equipped with a turntable 18. A drop tube 5 is installed at the upper end of the threaded telescopic rod 2. A discharge pipe 6 is inclinedly connected to the bottom of the front of the drop tube 5. A collection hopper 7 is connected to the upper end of the drop tube 5. A fixed inclined plate 8 is installed on the left side of the inner cavity of the collection hopper 7. A movable inclined plate 9 is fitted to the top of the fixed inclined plate 8. A pulling block 11 is installed at the right end of the movable inclined plate 9 through the collection hopper 7. A positioning plate 12 is rotatably installed in the middle of the pulling block 11 through the cooperation of a torsion spring and a shaft. The left end of the positioning plate 12 is connected to the surface of the collection hopper 7. A pull rope 13 is installed on the right side of the bottom of the pulling block 11. A pulling rod 14 is installed at the lower end of the pull rope 13. A limit spring 16 is sleeved on the surface of the pulling rod 14.

[0023] This technical solution, through the cooperation of the threaded telescopic rod 2 and the drive screw 3, can flexibly adjust the height to easily handle hazelnuts of different growth heights. It solves the inconvenience and safety hazards of using ladders and other tools for high-altitude harvesting. The staggered design of the fixed inclined plate 8 and the movable inclined plate 9 inside the collection bucket 7, together with components such as the pull rope 13 and the pull rod 14, enables convenient harvesting. Moreover, the harvested hazelnuts can be discharged in an orderly manner through the drop pipe 5 and the discharge pipe 6, achieving simultaneous harvesting and collection, reducing the workload of subsequent sorting, and greatly improving harvesting efficiency.

[0024] Example 2:

[0025] Based on Embodiment 1, this utility model is as follows: Figure 4 As shown, support springs 10 are installed on both the front and rear sides of the top of the movable inclined plate 9. The right end of the support spring 10 is connected to the inner wall of the collection hopper 7. The movable inclined plate 9 and the fixed inclined plate 8 are both provided with staggered limiting grooves.

[0026] Adopting such Figure 1 The technical solution shown allows the installation of the support spring 10 to provide a stable restoring force after the movable inclined plate 9 is pulled, ensuring that it quickly returns to its initial state of contact with the fixed inclined plate 8, preparing for the next harvest and reducing the hassle of manual reset. The misaligned limiting grooves on the movable inclined plate 9 and the fixed inclined plate 8 can prevent hazelnuts from falling prematurely under normal conditions. When the movable inclined plate 9 is pulled to align the limiting grooves, the harvested hazelnuts can pass smoothly into the collection structure, precisely controlling the timing of the hazelnuts' fall and improving the continuity and reliability of the harvesting and collection process.

[0027] Secondly, in the technical solution, a limiting frame 15 is fixedly installed on the right side of the fixed frame 1, one end of the pull rod 14 is located inside the limiting frame 15, the limiting spring 16 is located inside the limiting frame 15, and its end is connected to the inner wall of the limiting frame 15; a fixed handle 4 is fixedly installed on the left side of the fixed frame 1, and a pull ring 17 is installed at the lower end of the pull rod 14.

[0028] Its adoption is as follows Figure 1 The technical solution shown provides a stable installation space and motion guide for the pull rod 14 and the limit spring 16, effectively limiting the movement trajectory of the pull rod 14 and preventing it from deviating or shaking during the pulling process, ensuring the precise transmission of the pull rope 13, and also making the extension and retraction of the limit spring 16 more stable, ensuring the reliability of the reset function; the fixed handle 4 makes it easy for the user to hold the device stably and improves the control force during operation, while the pull ring 17 at the lower end of the pull rod 14 makes it easy for the hand to apply force, making the pulling action more effortless and convenient. The overall structure makes the picking operation smoother and more efficient.

[0029] Example 3:

[0030] This utility model is as follows Figures 1-5As shown, the threaded telescopic rod 2 is fixedly installed on both sides of one end inside the fixed frame 1 with limiting slide rods 19. The limiting slide rod 19 is embedded with a sliding limiting block 20, and the outer side of the limiting block 20 is connected to the inner wall of the fixed frame 1. The bottom of the inner cavity of the drop pipe 5 is inclinedly installed with a guide plate, and the guide plate is provided with a guide groove inside, which corresponds to the pipe opening of the discharge pipe 6.

[0031] By adopting the above technical solution, the cooperation between the limiting slide bar 19 and the limiting block 20 provides precise guidance for the lifting and lowering movement of the threaded telescopic rod 2, which can effectively prevent it from rotating or deviating during the height adjustment process, ensuring that the threaded telescopic rod 2 always moves stably along a fixed trajectory, making the height adjustment more stable and reliable; the inclined guide plate in the drop tube 5 and the corresponding discharge pipe 6 opening can efficiently guide the falling hazelnuts, preventing the hazelnuts from accumulating in the drop tube 5, and allowing them to smoothly enter the discharge pipe 6 along the guide path, ensuring the continuity of the collection process and improving the overall harvesting efficiency.

[0032] The working principle of this utility model is as follows: When harvesting is required, the pull ring 17 pulls the pull rod 14, which moves within the limiting frame 15 and compresses the limiting spring 16. The pull rod 14 drives the pull block 11 to rotate around the shaft via the pull rope 13. The pull block 11 drives the movable inclined plate 9 to rotate to the right, compressing the support spring 10. At this time, the movable inclined plate 9 separates from the limiting groove on the fixed inclined plate 8. Holding the fixed frame 1, the collecting bucket 7 is aligned with the hazelnuts and placed inside. The hazelnuts are then secured in the collecting bucket by the limiting groove. Inside the collection hopper 7, the limit on the pull rod 14 is released, and the support spring 10 presses against the movable inclined plate 9 and locks it to the outside of the upper end of the hazelnut branch. By pulling the collection hopper 7, the hazelnuts can be picked off and discharged from the discharge pipe 6 under the action of the guide plate and guide groove for easy collection. In addition, by holding the fixed handle 4 with one hand and rotating the drive screw 3 through the turntable 18 with the other hand, the length of the threaded telescopic rod 2 can be adjusted, and the length of the drop pipe 5 and the collection hopper 7 can be adjusted simultaneously to pick hazelnuts at high positions.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
