Abstract
Description
Technical Field
[0001] This invention relates to the field of fruit harvesting technology, specifically to a vibrating harvester for goji berries. Background Technology
[0002] With the improvement of people's living standards and the enhancement of health awareness, goji berries, as a crop with excellent food and medicinal properties, are increasingly favored by people. The demand and planting volume are constantly expanding. However, due to the characteristics of goji berries, such as thin skin, small size, large quantity and dense growth, goji berry harvesting has become a highly seasonal and labor-intensive task. The harvesting cost is high, the efficiency is low, and it is easy to prick hands when picking by hand. It is a time-consuming and labor-intensive part of the entire production process.
[0003] Currently, goji berry harvesting is mainly done manually or by machines. Manual harvesting is labor-intensive and inefficient, making it unsuitable for large-scale goji berry cultivation. With the expansion of goji berry planting, mechanized harvesting has become an inevitable choice to improve production efficiency. Currently, mechanized goji berry harvesting mainly consists of a motor, a high-frequency generator, a drive shaft, and a branch grabber. Its working principle involves placing the goji berry branch into the grabber, which in turn drives the drive shaft to rotate, causing the grabber to rotate. This rotation vibrates the goji berry branch, separating the fruit from the stalk for harvesting. However, in practical application, the rotation of the grabber generates a significant impact, resulting in damage or breakage of some goji berry branches each year. This leads to the death of some branches the following year, causing irreversible damage to the goji berry tree and affecting yield. Furthermore, the excessive impact also damages the peel and compresses the pulp of some harvested fruits, increasing fruit loss.
[0004] Therefore, there is a need for a vibrating goji berry harvester that avoids causing significant impact to goji berry branches and fruits when harvesting goji berries. Summary of the Invention

[0019] The following detailed description of a specific embodiment of the present invention is provided in conjunction with the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0022] Furthermore, in the description of this invention, "a plurality of" refers to two or more. The terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
[0023] Example 1 This invention provides a vibrating harvester for goji berries, such as... Figure 1As shown, it includes: a drive structure, a flexible shaft 5, and a picking structure. The drive structure has an output end; one end of the flexible shaft 5 is connected to the output end of the drive structure. The drive structure is used to drive the flexible shaft 5 to rotate, and the flexible shaft 5 is used to transmit the rotational motion of the drive structure. The flexible shaft 5 is made of a special elastic alloy material, such as 7075 aluminum alloy or 304 stainless steel, and has high torque transmission capacity (≥3 N·m) and good flexibility. It has an inner diameter of 6 mm, an outer diameter of 16 mm, and an effective length of up to 1.2 m, which can mitigate impact. The picking structure is used to mitigate impact when picking goji berries. In this embodiment, the picking structure includes a first outer shell 6, a reciprocating swing assembly, and a vibration rod 22. The reciprocating swing assembly is disposed inside the first outer shell 6, and the end of the flexible shaft 5 facing away from the drive structure passes through one end of the first outer shell 6. The reciprocating swing assembly has… The device has an input and an output end. The flexible shaft 5 is connected to the input end of the reciprocating oscillation assembly, which transmits the rotational motion to the assembly. The vibrating rod 22 is located at the other end of the first housing 6. A buffer is provided around the vibrating rod 22. The vibrating rod 22 acts directly on the goji berry branches, vibrating the goji berries down. The buffer further cushions the impact. The vibrating rod 22 is connected to the output end of the reciprocating oscillation assembly, which converts the rotational motion of the flexible shaft 5 into the reciprocating oscillation motion of the vibrating rod 22, thus vibrating the goji berries down for harvesting. Compared to continuous rotation, reciprocating oscillation is gentler on the fruit, reducing the damage rate from 30%-40% to below 10%. Furthermore, reciprocating motion is more energy-efficient than continuous rotation. In use, the drive structure rotates the flexible shaft 5, which transmits the motion to the reciprocating oscillation assembly, which then drives the vibrating rod 22 in its reciprocating oscillation motion. First, the flexible shaft 5 provides initial transmission, mitigating the impact force. Second, the reciprocating oscillating assembly causes the vibrating rod 22 to oscillate back and forth, preventing damage to the branches from entanglement and converting rotational motion into reciprocating motion, thus reducing the direct impact on the branches and preventing damage or breakage. Finally, the vibrating rod 22 directly impacts the goji berry branches, and a buffer is added to it for further cushioning. In summary, this structure reduces the direct impact of the drive structure, preventing damage or breakage of branches and fruits, as well as damage to the peel and compression of the fruit pulp caused by excessive impact during harvesting. A handle 8 is attached to the outer wall of the first outer shell 6, facilitating gripping the entire harvesting structure. The overall structure is lightweight, allowing the drive structure to be carried on the worker's back or waist for easy hand-held harvesting.
[0024] This embodiment provides a specific structure for a reciprocating oscillating component, such as... Figure 2As shown, the reciprocating oscillating assembly further includes: an eccentric shaft 11, a guide block 13, and a first rotating shaft 14. One end of the eccentric shaft 11 is fixed to the end of the flexible shaft 5 that is away from the drive structure. The rotation of the flexible shaft 5 drives the eccentric shaft 11 to rotate synchronously. The eccentric shaft 11 is rotatably connected to the inner wall of the first housing 6 through the first bearing 18. The rotation of the eccentric shaft 11 does not affect the first housing 6. A guide groove is provided on the guide block 13. The guide groove is opened along the length direction of the guide block 13. The end of the eccentric shaft 11 that is away from the flexible shaft 5 is slidably connected in the guide groove. When the eccentric shaft 11 rotates, one end slides back and forth in the guide groove, while driving the guide block 13 to oscillate. Both ends of the first rotating shaft 14 are rotatably connected to the first housing 6, specifically through the second bearing 19. One end of the guide block 13 is fixed to the circumference of the first rotating shaft 14. When the guide block 13 oscillates, it can drive the first rotating shaft 14 to oscillate. One end of the vibration rod 22 is connected to the first rotating shaft 14. The working principle of the reciprocating oscillating component in this embodiment is as follows: the driving structure drives the flexible shaft 5 to rotate, thereby driving the eccentric shaft 11 to rotate synchronously. When the eccentric shaft 11 rotates, one end slides back and forth in the guide groove, thereby driving the guide block 13 to oscillate, driving the first rotating shaft 14 to oscillate, so that the vibrating rod 22 connected to the first rotating shaft 14 oscillates back and forth to harvest goji berries. The length of the guide groove can be set according to the actual harvesting needs to realize the oscillation of the vibrating rod 22 within a reasonable angle range. In this embodiment, the oscillation range is selected from 0° to 180°.
[0025] Furthermore, the buffer is a flexible tube, which is fitted around the circumference of the vibrating rod 22. In this embodiment, the flexible tube is made of medical-grade silicone material with a Shore A hardness of 60 to 70 degrees and a wall thickness of 2-3 mm. The vibrating rod 22 is rigid and can vibrate the goji berries down. At the same time, the silicone flexible tube fitted around the circumference of the vibrating rod 22 has both sufficient strength and appropriate flexibility. The diameter of the flexible tube is slightly larger than the diameter of the vibrating rod 22, which can produce slight deformation when it comes into contact with the branches, avoiding direct impact on the branches and reducing the impact on the branches to prevent damage and breakage of the goji berry branches.
[0026] This embodiment provides a specific method for a driving structure, such as... Figure 2As shown, the drive structure further includes: a housing 1, a controller 3, and a drive component 2. The controller 3 is housed inside the housing 1; the drive component 2 is located inside the housing 1, which protects its internal structure. The drive component 2 has an output shaft, which is connected to one end of a flexible shaft 5. The drive component 2 is electrically connected to the controller 3. In this embodiment, the drive component 2 is a drive motor (895 motor). The controller 3 can control the start / stop and speed of the drive motor, adjusting the appropriate speed as needed to avoid large impacts. It can also adapt to the harvesting of fruits at different maturity levels. By controlling the vibration frequency and amplitude, only mature fruits are shaken off, and the retention rate of immature fruits reaches 95%. In this embodiment, the controller 3 adjusts the speed of the drive motor through a 40A stepless speed regulator. The vibration frequency can be precisely adjusted within the range of 300-600 times / minute, and the amplitude can be controlled within 5mm-10mm. The output shaft of the drive motor is connected to one end of the flexible shaft 5 through a coupling 4. The coupling 4 uses a special locking mechanism to ensure stable and reliable power transmission between the flexible shaft 5 and the drive motor, with a speed loss of less than 3%.
[0027] Example 2 As a further improvement on Example 1, in order to further mitigate the impact, such as Figure 3As shown, the connection structure between one end of the vibrating rod 22 and the first rotating shaft 14 includes: a first gear 16, a second rotating shaft 15, and a second gear 17. The first gear 16 is fixedly mounted on the circumference of the first rotating shaft 14, and the swinging of the first rotating shaft 14 can drive the first gear 16 to swing synchronously. The two ends of the second rotating shaft 15 are rotatably connected to the first housing 6, and the second rotating shaft 15 is rotatably connected to the first housing 6 through a third bearing 20. One end of the vibrating rod 22 is connected to one end of the second rotating shaft 15. The second gear 17 is fixedly mounted on the circumference of the second rotating shaft 15, and the second gear 17 meshes with the first gear 16. The first gear 16 can drive the second gear 17 to swing synchronously, thereby driving the second rotating shaft 15 to swing. In use, the swinging of the first rotating shaft 14 synchronously drives the first gear 16 to swing, and the second gear 17 meshes with the first gear 16. Because the swinging of the first gear 16 can drive the swinging of the second gear 17 synchronously, thereby driving the second rotating shaft 15 to swing, the vibrating rod 22 connected to the second rotating shaft 15 swings, thus realizing the harvesting of goji berries. This embodiment is equivalent to setting a gear set for transmission between the vibrating rod 22 and the first rotating shaft 14. While enabling the vibrating rod 22 to swing and harvest the fruit, it also has the following functions: 1. Vibration frequency increase function: The first gear 16 can be set to 30 teeth and the second gear 17 to 15 teeth, forming a 2:1 speed-up transmission ratio. When the reciprocating oscillation frequency of the first rotating shaft 14 is 200 times / minute, through gear speed-up transmission, the reciprocating oscillation frequency of the second rotating shaft 15 and the vibrating rod 22 is increased to 400 times / minute. High-frequency vibration (400-600 times / minute) is more in line with the natural frequency of goji berry fruit, improving harvesting efficiency. 2. Mechanical optimization design: Lowering the input requirements, the eccentric shaft 11 only needs to generate a lower frequency (200-300 times / minute) reciprocating motion, reducing wear on the eccentric shaft 11. Furthermore, the low-speed operation of the eccentric shaft 11 and the guide groove structure results in a longer lifespan and extended maintenance cycle. 3. Precise Vibration Characteristic Control: A 2:1 speed-increasing ratio converts the 150-300 reciprocating motion of the eccentric shaft 11 into a high-frequency vibration of 300-600 times per minute for the vibrating rod 22. This high-frequency, small-amplitude vibration (5-8mm) is optimal for goji berry harvesting, effectively shaking off mature fruits while protecting immature fruits and branches. 4. Energy Transfer Efficiency: The larger first gear 16 has greater rotational inertia, storing and releasing vibrational energy for smoother vibration. The gear transmission system itself possesses elasticity and damping, buffering vibration impacts and reducing stress on branches. 5. Structural Layout Advantages: The speed-increasing transmission allows for a smaller second shaft 15, reducing the overall weight of the harvesting structure and facilitating operation by staff.
[0028] like Figure 3As shown, furthermore, multiple vibrating rods 22 are provided. The use of multiple vibrating rods 22 can improve harvesting efficiency. It also includes: a fixed disk 21 disposed at one end of the first housing 6; one end of a second rotating shaft 15 fixed to one side of the fixed disk 21; the second rotating shaft 15 drives the fixed disk 21 to reciprocate; and multiple vibrating rods 22 are evenly distributed on the other side of the fixed disk 21, with the axial direction of the vibrating rods 22 aligned with the axial direction of the second rotating shaft 15. The second rotating shaft 15 drives the fixed disk 21 to reciprocate, thereby driving the multiple vibrating rods 22 to rotate reciprocally within a certain angle range, thus realizing the harvesting of goji berries. Furthermore, as... Figure 3 As shown, the fixed plate 21 and the second rotating shaft 15 adopt a special boss-groove connection structure to ensure accurate and lossless vibration transmission, while ensuring that the vibration direction is consistent with the branch growth direction and reducing lateral impact. Through experimental verification, the design of the picking structure in this embodiment can reduce the fruit damage rate to below 10%, which is 60%-75% lower than that of traditional equipment, while increasing the picking efficiency by more than 40%.
[0029] In this embodiment, the other structures are the same as in embodiment 1, except that optimizations have been made to embodiment 1.
[0030] Example 3 As a further improvement on Embodiment 1, the eccentric shaft 11 is further provided with a bearing housing 10 circumferentially mounted thereon. The bearing housing 10 supports the first bearing 18, which is housed within the bearing housing 10. The eccentric shaft 11 is rotatably connected to the inner wall of the first housing 6 via the bearing housing 10. Figure 4 As shown, it also includes a damping structure 12 disposed on the bearing housing 10. The damping structure 12 can further reduce the impact transmitted to the vibrating rod 22, such as... Figure 5As shown, the damping structure 12 in this embodiment includes: a first connecting ring 23, a second connecting ring 27, and a damping assembly. The first connecting ring 23 is fitted around the bearing housing 10. The inner ring sidewall of the first connecting ring 23 is connected to the bearing housing 10 around the bearing housing 10 by multiple connecting rods 28. That is, the bearing housing 10 has multiple connecting rods 28 around its circumference. The ends of the multiple connecting rods 28 away from the bearing housing 10 are fixed to the inner ring sidewall of the first connecting ring 23. The multiple connecting rods 28 are evenly distributed to ensure that the force transmitted to the first connecting ring 23 is uniform. The first connecting ring 23 and the connecting rods 28 are made of a material with micro-elastic deformation, such as iron sheet. The second connecting ring 27 is fitted around the first connecting ring 23. The connecting ring 23 is circumferentially connected, and the outer ring sidewall of the second connecting ring 27 is fixed to the inner wall of the first housing 6. The first housing 6 supports the second connecting ring 27. The second connecting ring 27 can be made of a material with a certain rigidity. Multiple sets of shock-absorbing components are set between the outer ring sidewall of the first connecting ring 23 and the inner ring sidewall of the second connecting ring 27. This can reduce the impact force transmitted to the first connecting ring 23 and the bearing seat 10, and also reduce the impact force transmitted to the handle 8. This reduces the fatigue of the workers' hand muscles and greatly improves the comfort of operation and the health of the workers.
[0031] This embodiment provides a specific method for providing a shock absorption component, such as... Figure 6 As shown, the shock absorption assembly further includes: multiple balls 24, multiple sliders 26, and multiple connectors. A first groove is formed on the outer sidewall of the first connecting ring 23, extending circumferentially, and multiple balls 24 are slidably connected within the first groove. A second groove is formed on the inner sidewall of the second connecting ring 27, extending circumferentially, and multiple sliders 26 are slidably connected within the second groove. Multiple sets of connectors correspond one-to-one with the multiple balls 24. Each set of connectors includes two first steel plates 25, each disposed on the sidewall of a ball 24. The ends of the two first steel plates 25 facing away from the ball 24 are disposed on the sidewalls of two adjacent sliders 26. The two first steel plates 25 connect each ball 24 to its corresponding two adjacent sliders 26, dispersing the impact force to both sides. The first steel plates 25 have the function of generating micro-elastic deformation. When the shock-absorbing structure 12 in this embodiment is subjected to force, the force is transmitted to all sides, which will cause the shock-absorbing structure 12 to deform. The ball 24 in the shock-absorbing structure 12 slides in the first groove. During the sliding process, the ball 24 and the slider 26 are connected by the first steel plate 25. The first steel plate 25 moves to both sides of the two connected sliders 26 with the ball 24 as the point, so that the slider 26 slides in the second groove, thereby achieving deformation and thus achieving the effect of shock absorption.
[0032] like Figure 6As shown in the figure, there are three sets of damping components. Furthermore, two second steel plates 29 are respectively provided on the two sliders 26 between two adjacent sets of damping components, and the two second steel plates 29 are adjacent at the ends away from the sliders 26. That is to say, the two outermost sliders 26 of each set of damping components are provided with second steel plates 29. The second steel plates 29 have a certain rigidity and micro-elastic deformation function. By setting the second steel plates 29, the sliders 26 are prevented from excessive displacement during deformation, which would cause multiple sets of damping components to be concentrated and stuck together, thus failing to achieve the effect of deformation damping. The gap between the two second steel plates 29 in two adjacent sets of damping components is the amount of displacement left for deformation.
[0033] In this embodiment, the other structures are the same as in embodiment 1, except that optimizations have been made to embodiment 1.
[0034] The advantages of this invention are that, in use, the drive structure rotates the flexible shaft, which transmits the motion to the reciprocating oscillating assembly, which in turn drives the vibrating rod to reciprocate. Firstly, the flexible shaft transmission initially reduces the impact force. Secondly, the reciprocating oscillating assembly causes the vibrating rod to vibrate, which, on the one hand, prevents damage to the branches from entanglement, and on the other hand, converting rotational motion into reciprocating motion reduces the direct impact force on the branches, preventing damage or breakage. Finally, the vibrating rod directly acts on the goji berry branches, and the inclusion of a buffer on the vibrating rod further enhances the cushioning effect. In summary, this structure reduces the direct impact force of the drive structure, preventing damage or breakage of the branches and fruits, as well as damage to the peel and compression of the fruit pulp, caused by significant impact during goji berry harvesting.
[0035] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
