A vibrating seabuckthorn harvesting device

Abstract

This invention relates to a vibratory seabuckthorn harvesting device. Its harvesting mechanism uses a mounting plate movably mounted on a frame to move a harvesting plate and harvesting arm, allowing the harvesting arm to clamp seabuckthorn branches. The vibration of the harvesting plate and arm directly applies excitation force to the clamped branches, causing the fruit to fall. This method avoids the dispersion of excitation force, significantly improving the harvesting rate and efficiency, and reducing damage to the fruit and trees. The collection mechanism releases an elastic cloth via an electric roller, and the automatic opening action of the tensioning component unfolds and tensions the first elastic cloth, which in turn causes a second elastic cloth to adhere to and wrap around the branches, forming a sealed collection area. This design eliminates the need for complex transmission mechanisms and additional baffle assemblies, simplifying the overall structure and reducing manufacturing costs and failure rates. This invention achieves efficient, low-damage, and mechanized seabuckthorn harvesting, solving the problems of low efficiency, significant fruit damage, and complex collection structures in existing devices.

Description

Technical Field

[0001] This invention relates to the field of sea buckthorn harvesting technology, and in particular to a vibrating sea buckthorn harvesting device. Background Technology

[0002] Sea buckthorn, a deciduous shrub belonging to the Elaeagnaceae family, is widely distributed across Eurasia. Also known as vinegar willow or sour thorn, it is mainly distributed in more than twenty provinces and regions in China, including Hebei, Shanxi, and Qinghai. Sea buckthorn possesses a well-developed root system and strong sprouting and suckering abilities, thus playing an important role in windbreak and sand fixation, as well as soil and water conservation. Furthermore, sea buckthorn berries are rich in various vitamins, proteins, flavonoids, carotene, and other nutrients, possessing high medicinal and edible value. Cultivating sea buckthorn can bring significant economic benefits.

[0003] Sea buckthorn berries typically grow in dense clusters. The berries are small, with thin skin and short stalks. The strong bond between the stalk and the branch, coupled with the numerous thorns on the branches, makes manual harvesting inefficient and labor-intensive. Currently, there are two main traditional methods of manual harvesting: one is to harvest directly after the berries have frozen solid when winter temperatures drop below -20°C; the other is to prune the entire fruiting branch for harvesting. While the former reduces damage during fresh berry harvesting, the gap between berry ripening and the suitable low temperature for harvesting is several months, easily leading to nutrient loss and bird pecking problems. Furthermore, working in low-temperature environments requires a high level of tolerance from the harvesters. The latter method, while allowing for fresh berry harvesting, severely impacts the sea buckthorn tree's fruiting capacity for the following year, harming the tree's growth. In addition, manual harvesting generally suffers from low efficiency, high cost, high labor intensity, and susceptibility to thorn damage.

[0004] To improve harvesting efficiency and reduce labor intensity, some mechanized harvesting devices have been developed. For example, Chinese patent application CN118592206A, published on September 6, 2024, discloses a seabuckthorn harvesting device that uses a striking mechanism to strike branches, causing the fruits to fall through random vibration, and then collects them through a collection mechanism. While this device achieves a certain degree of mechanization, its striking method involves a single striking rod acting on multiple branches simultaneously, resulting in dispersed vibration force, low harvesting rate, and unstable harvesting results. Furthermore, the striking process can easily cause direct impact on the fruits, resulting in mechanical damage and affecting fruit quality.

[0005] Another Chinese patent application, CN109699299A, published on May 3, 2019, discloses a multi-point clamping and opposing vibration device for harvesting wolfberries and its PLC control method. This device can also be used for harvesting sea buckthorn. It directly clamps and vibrates the fruit branches using multiple clamping rods, concentrating the vibration force on a single branch, avoiding energy dispersion, significantly improving the harvesting rate and efficiency, while reducing mechanical damage to the fruit and branches. However, this device lacks a collection mechanism; the shaken-off fruit falls directly to the ground and still needs to be picked up manually, increasing labor intensity and easily causing fruit contamination and damage.

[0006] Although CN118592206A includes a collection mechanism, its structure is quite complex. The main component of this mechanism is a collection umbrella consisting of two semi-umbrella assemblies, whose opening and closing action relies on a complex drive system. Specifically, each semi-umbrella assembly includes a fixed umbrella pole and multiple rotating umbrella poles, with a collection umbrella drive gear coaxially fixed at the base of each rotating umbrella pole. Multiple drive gears of varying sizes, located on the same side of the collection frame, mesh simultaneously with a collection umbrella drive rack. This rack is driven linearly by a telescopic cylinder, and the rack's movement causes all gears to rotate synchronously. Due to the different gear sizes, with the same rack displacement, each gear drives its connected rotating umbrella pole to rotate through different angles, thus achieving the unfolding and closing of the collection umbrella. While this drive method achieves the opening and closing function of the umbrella, it involves the coordination of multiple sets of gears, racks, and telescopic cylinders, resulting in a long transmission chain, complex structure, and high requirements for manufacturing and assembly precision, increasing manufacturing costs and failure rates.

[0007] Furthermore, since the canopy of the collecting umbrella cannot tightly wrap around the sea buckthorn trunk, an additional baffle assembly is installed to seal the gap between the trunk and the umbrella, preventing the fruit from falling through. This assembly consists of multiple blades hinged to the collecting frame by pins and a return spring. When the harvesting device approaches the trunk, the trunk pushes the blades to rotate around the pins, and the multiple blades together wrap around the trunk, forming a seal. After the operation is completed, the blades return to their original position under the action of the return spring. The introduction of the baffle assembly further increases the complexity of the collecting mechanism and affects the practicality of the harvesting device. Summary of the Invention

[0008] The purpose of this invention is to provide a vibratory seabuckthorn harvesting device to solve the technical problem of complex structure caused by the use of multiple gears, racks, telescopic cylinders and additional baffle components in the collection mechanism of existing seabuckthorn harvesting devices.

[0009] The technical problem solved by this invention can be achieved by the following solutions:

[0010] A vibratory seabuckthorn harvesting device includes a frame, comprising:

[0011] The harvesting mechanism includes a harvesting board and multiple harvesting arms fixed on the harvesting board. The harvesting board is movably mounted on the frame via a mounting plate. The harvesting board and harvesting arms can vibrate relative to the mounting plate. The harvesting arms are used to clamp and vibrate the sea buckthorn branches.

[0012] A collection mechanism for collecting shaken-down sea buckthorn berries includes a collection frame, an electric roller rotatably mounted thereon, a first elastic cloth with one end wound around the electric roller and the other end fixed to a support rod, a second elastic cloth fixed to the support rod, and a tensioning assembly for tensioning the first elastic cloth. The tensioning assembly includes a first tensioning arm with one end rotatably connected to the support rod and the other end rotatably connected to one end of a second tensioning arm. The other end of the second tensioning arm is rotatably mounted on the collection frame. A tensioning spring is provided on the first tensioning arm with one end fixed to the first tensioning arm and the other end fixed to the second tensioning arm via a spring connecting rope.

[0013] When the electric roller releases the first elastic cloth, the first tension arm and the second tension arm, which are set at an angle, can open under the action of the tension spring. During the opening process, the first elastic cloth is unfolded and tensioned, so as to drive the second elastic cloth to contact and wrap the sea buckthorn branches.

[0014] Furthermore: the harvesting arm includes a harvesting rod that is detachably and fixedly mounted on the harvesting plate. A U-shaped harvesting head is fixedly mounted at the end of the harvesting rod. Multiple harvesting head rollers that can contact the sea buckthorn branches are rotatably mounted on the U-shaped harvesting head. The sea buckthorn branches can be clamped between the multiple harvesting head rollers.

[0015] Furthermore: when the electric roller releases the first elastic cloth, the first tension arm and the second tension arm are set at an angle, the tension spring is in a stretched state, and under the restoring force of the tension spring, the angle between the first tension arm and the second tension arm increases, thereby opening.

[0016] Furthermore: a lower rail and an upper rail are fixedly installed on the frame, and an installation plate is provided on the upper and lower sides of the picking plate. A sliding pin is fixed on the installation plate. The sliding pin of the installation plate located on the lower side of the picking plate is slidably installed in the lower rail, and the sliding pin of the installation plate located on the upper side of the picking plate is slidably installed in the upper rail.

[0017] A drive motor is fixed on the mounting plate located on the lower side of the picking plate. A drive gear is fixed on the output shaft of the drive motor. The drive gear meshes with a rack fixed on the frame. When the drive motor starts, it drives the drive gear to rotate, thereby moving the mounting plate along the frame.

[0018] Furthermore: the picking board is provided with a vibration drive mechanism, the vibration drive mechanism includes a rotating shaft base fixedly installed on the picking board and a rotating shaft rotatably installed on the rotating shaft base, and an eccentrically set base block is fixedly installed on the rotating shaft; the picking board is also equipped with a vibration drive motor for driving the rotating shaft to rotate.

[0019] When the eccentric base block rotates with the shaft, it can drive the picking plate to vibrate relative to the mounting plate.

[0020] Furthermore: an installation plate is provided on the upper and lower sides of the picking board, and guide posts are fixed on the upper and lower sides of the picking board. A connecting sleeve is fixedly installed on the installation plate. The guide post located on the lower side of the picking board can be slidably inserted into the connecting sleeve of the lower installation plate, and the guide post located on the upper side of the picking board can be slidably inserted into the connecting sleeve of the upper installation plate.

[0021] The connecting sleeve is equipped with a buffer spring, which is sleeved on the outside of the corresponding guide post and is located between the picking plate and the mounting plate.

[0022] Furthermore: a first connecting seat is fixedly installed at the end of the first tensioning arm, and a second connecting seat is fixedly installed at the end of the second tensioning arm; the second connecting seat is rotatably connected to the first connecting seat by bolts, so that the second tensioning arm can rotate relative to the first tensioning arm about the axis of the bolts.

[0023] Furthermore: a collection conveyor belt is installed on the collection rack, and the collection conveyor belt is located below the first elastic cloth; conveyor belt baffles fixed to the collection rack are provided on both sides of the collection conveyor belt; a conveyor belt motor for driving the collection conveyor belt is fixedly installed on the collection rack; and a collection box is provided below the end of the collection conveyor belt.

[0024] Furthermore: the cross-section of the picking board is semi-circular, and the mounting plate adopts a semi-circular structure that matches the picking board;

[0025] The harvesting mechanism is provided in two sets, which are symmetrically arranged on the frame, and the semi-circular openings of the harvesting plates of the two sets of harvesting mechanisms are arranged opposite each other.

[0026] Furthermore: the collection mechanism is provided in two sets, which are symmetrically arranged on the frame and located directly below the two harvesting mechanisms; when the first elastic cloth of the two collection mechanisms is unfolded, it can respectively drive the second elastic cloth connected to it to contact and wrap the sea buckthorn branches.

[0027] The vibrating seabuckthorn harvesting device of the present invention effectively solves the technical problems of complex structure of collection mechanism, low harvesting efficiency and easy damage to fruit in the prior art by cooperating the collection mechanism and the picking mechanism.

[0028] During collection, the collecting mechanism releases a first elastic cloth via an electric roller. A tensioning assembly, including a first tensioning arm, a second tensioning arm, and a tensioning spring, automatically unfolds and tensions the first elastic cloth. This, in turn, causes a second elastic cloth to adhere to and wrap around the seabuckthorn branches, forming a tight enclosure and reducing the likelihood of seabuckthorn berries falling through gaps between the branches and the collecting cloth. This collecting mechanism features a simple structure, simplifying the drive and transmission systems of existing fruit collecting mechanisms. It eliminates the need for complex multi-gear and rack-and-pinion transmission mechanisms, reducing manufacturing costs and failure rates. By directly contacting and wrapping the seabuckthorn branches with the collecting cloth, there is no need for additional baffle assemblies to enclose the trunk, further simplifying the structure and improving the reliability and practicality of the device.

[0029] During harvesting, the mounting plate moves the entire harvesting mechanism, allowing multiple harvesting arms to approach and clamp the target branch. The harvesting plate and the harvesting arms fixed to it then vibrate relative to the mounting plate, directly transmitting the vibrational force to the clamped branch. This vibration breaks the bond between the seabuckthorn berry stalk and the branch, effectively shaking the fruit off. By directly clamping and vibrating the seabuckthorn branch with the harvesting arms, the vibrational force can be precisely and concentrated on a single branch, effectively avoiding the dispersion of vibrational energy, thus significantly improving the fruit removal rate and harvesting efficiency. Simultaneously, this harvesting method, through clamping and vibration rather than striking, avoids direct impact on the fruit and branch, reducing damage to both the fruit and the tree.

[0063] To make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0064] Figure 1 This is a schematic diagram of the structure of the vibrating seabuckthorn harvesting device according to this embodiment, as shown below. Figure 1 As shown, the vibratory seabuckthorn harvesting device includes a frame 1 (the structure of which is also shown in...) Figure 2 (middle) and the picking mechanism 2, which is slidably installed inside the frame 1. For example... Figure 3 , 4 As shown, the harvesting mechanism 2 includes a harvesting plate 21 and multiple harvesting arms 22 fixedly mounted on the harvesting plate 21. The harvesting plate 21 is connected to the frame 1 via a mounting plate 231, which is slidably disposed inside the frame 1. This allows the mounting plate 231 to move the entire harvesting mechanism 2 along the frame 1 during sliding. When the harvesting mechanism 2 moves, the harvesting arms 22 can clamp sea buckthorn branches. The harvesting plate 21 can vibrate relative to the mounting plate 231 and the frame 1, causing the harvesting arms 22 mounted on it to vibrate synchronously. Figure 4 , 5 As shown, a buffer spring 232 is installed between the picking plate 21 and the mounting plate 231 (shown in...). Figure 4 The mechanism 22 (in the middle) buffers and protects the harvesting plate 21 during vibration. After the harvesting arm 22 clamps the sea buckthorn branch, the sea buckthorn fruit on the branch falls off under the action of vibration, thus realizing the harvesting of the sea buckthorn fruit.

[0065] like Figure 1 As shown, a collecting mechanism 3 is also installed on the frame 1, located below the harvesting mechanism 2, for collecting the sea buckthorn berries that have fallen due to vibration. Figure 6 , 7As shown, the collection mechanism 3 includes a collection frame 31 fixed below the frame 1. An electric roller 32 is rotatably mounted on the collection frame 31. One end of a first elastic cloth 331 is wound around the electric roller 32, and the other end is fixedly connected to a support rod 341 (shown in the diagram). Figure 7 (In the middle); support rod 341 is located below the first elastic cloth 331, and a second elastic cloth 332 is fixedly installed on it. The end of the second elastic cloth 332 away from the support rod 341 can contact the sea buckthorn branch. In this embodiment, the electric roller 32 is driven by a motor, and driving the electric roller to rotate by a motor is a conventional technical means.

[0066] The collecting mechanism 3 also includes a tensioning component 35 capable of causing the first elastic fabric 331 to unfold and maintain tension, such as Figure 7 As shown, the tensioning assembly 35 includes a first tensioning arm 351 and a second tensioning arm 352. One end of the first tensioning arm 351 is rotatably connected to the support rod 341, and the other end is rotatably connected to one end of the second tensioning arm 352 (the structure after the first tensioning arm 351 and the second tensioning arm 352 are connected is shown in...). Figure 8 , Figure 9 (In the middle), the other end of the second tensioning arm 352 is rotatably mounted on the collection rack 31. For example... Figure 10 , 11 As shown, a tension spring 353 is provided inside the first tensioning arm 351. One end of the tension spring 353 is fixed inside the first tensioning arm 351, and the other end is fixed to the second tensioning arm 352 through a spring connecting rope 354. When the first tensioning arm 351 and the second tensioning arm 352 are set at an angle (i.e., there is an angle between the first tensioning arm 351 and the second tensioning arm 352, and the angle is less than 180 degrees), the tension spring 353 is in a stretched state, so that the first tensioning arm 351 and the second tensioning arm 352 have an outward opening (i.e., the angle between the first tensioning arm 351 and the second tensioning arm 352 increases) and tend to straighten. When the tension spring 353 is in a stretched state, under the restoring force of the tension spring 353, the second tension arm 352 can be pulled through the spring connecting rope 354, causing the first tension arm 351 and the second tension arm 352 to rotate relative to each other, thereby causing the first tension arm 351 and the second tension arm 352 to open, and the included angle between them to increase.

[0067] At the start of the collection operation, the first elastic cloth 331 is initially wound onto the electric roller 32. At this time, the first tensioning arm 351 and the second tensioning arm 352 maintain a certain angle, and the tension spring 353 is in a stretched state. The electric roller 32 starts and releases the first elastic cloth 331. Under the restoring force of the tension spring 353, the first tensioning arm 351 and the second tensioning arm 352 gradually open, and the angle between the two arms gradually increases. During this process, the first tensioning arm 351 moves towards the sea buckthorn branch, pushing the support rod 341, which is rotatably connected to it, to move towards the sea buckthorn branch, thereby pulling the first elastic cloth 331, which is fixed to the support rod 341, to unfold, tension, and extend towards the sea buckthorn branch. As the first elastic cloth 331 unfolds, the second elastic cloth 332 connected to it also moves towards the sea buckthorn branch until it contacts the surface of the branch. During the continuous movement, as... Figure 12 As shown, the second elastic cloth 332 undergoes elastic deformation when blocked by the branches, allowing it to bend and partially wrap around the branches, forming a wrapping receiving surface. The sea buckthorn fruits that have fallen off due to vibration land on the surfaces of the second elastic cloth 332 and the first elastic cloth 331, thus collecting the sea buckthorn fruits.

[0068] In this embodiment, the vibratory seabuckthorn harvesting device moves to the side of a seabuckthorn tree and allows the tree to enter the frame 1 through an opening. After the tree is in place, the collecting mechanism 3 begins operation. The electric roller 32 starts, releasing the first elastic cloth 331 wound around it. At this time, the tension spring 353, which is in a stretched state, pulls the second tension arm 352 through the spring connecting rope 354, causing the angle between the first tension arm 351 and the second tension arm 352 to gradually increase, and the two arms open outward and tend to straighten. During this process, the first tension arm 351 pushes the support rod 341 to move towards the seabuckthorn branch, thereby pulling the first elastic cloth 331 to unfold and gradually tighten. As the first elastic cloth 331 unfolds, the second elastic cloth 332, which is fixedly connected to it through the support rod 341, also moves towards the seabuckthorn branch until it contacts the surface of the branch. The second elastic cloth 332 undergoes elastic deformation under the obstruction of the branches, bends to conform to the shape of the branches and partially wraps around them, forming a tightly fitting wrapping receiving surface, which is ready to collect the shaken-down fruits.

[0069] After the collecting mechanism 3 is in place, the harvesting mechanism 2 begins the harvesting operation. The mounting plate 231 moves along the frame 1, bringing the entire harvesting mechanism 2 closer to the sea buckthorn canopy, so that multiple harvesting arms 22 clamp the sea buckthorn branches to be harvested. In this embodiment, each harvesting arm 22 clamps a single sea buckthorn branch. After clamping, the harvesting plate 21 begins to vibrate relative to the mounting plate 231, causing all harvesting arms 22 to vibrate synchronously. The vibration energy acts directly on the branches clamped by the harvesting arms 22, breaking the bonding force between the fruit stalk and the branch, causing the sea buckthorn fruit to be continuously shaken off. The shaken-off fruit falls onto the surface of the unfolded second elastic cloth 332 and the first elastic cloth 331, thus collecting the sea buckthorn fruit.

[0070] Regarding the specific structure of the harvesting arm 22, further details are as follows: Figure 13 , 14 As shown, the harvesting arm 22 includes a harvesting rod 221 detachably and fixedly mounted on the harvesting plate 21. A U-shaped harvesting head 222 is fixedly mounted at the end of the harvesting rod 221. Multiple harvesting head rollers 223 that can contact the sea buckthorn branches are rotatably mounted on the U-shaped harvesting head 222. The sea buckthorn branches can be clamped between the multiple harvesting head rollers 223. Figure 15 The diagram illustrates the working state of the harvesting arm 22 clamping a single sea buckthorn branch using its U-shaped harvesting head 222. Since the harvesting head roller 223 is rotatably mounted on the U-shaped harvesting head 222, the contact between the harvesting head roller 223 and the sea buckthorn branch is a rolling contact, which reduces wear and tear on the sea buckthorn branch during harvesting. In this embodiment, the harvesting rod 221, U-shaped harvesting head 222, and harvesting head roller 223 are all made of elastic silicone material, allowing the harvesting arm 22 to adapt to the distribution of the branches and branches when entering the sea buckthorn clump, thereby reducing collisions and friction with the branches and effectively minimizing mechanical damage to the sea buckthorn branches and fruit.

[0071] like Figure 3 As shown, regarding the specific installation method between the picking plate 21 and the mounting plate 231, two mounting plates 231 are symmetrically arranged on the upper and lower sides of the picking plate 21, with the picking plate 21 sandwiched between them. Figure 16 As shown, to further improve the stability of vibration transmission and provide a buffering effect, guide posts 211 are fixed on the upper and lower sides of the picking plate 21, respectively. Correspondingly, as... Figure 17-19 As shown, connecting sleeves 233 are fixedly installed on the mounting plates 231 on both the upper and lower sides. Figure 5As shown, the guide post 211 located on the lower side of the picking plate 21 is slidably inserted into the connecting sleeve 233 of the lower mounting plate 231, and the guide post 211 located on the upper side of the picking plate 21 is slidably inserted into the connecting sleeve 233 of the upper mounting plate 231. A buffer spring 232 is provided inside each connecting sleeve 233, and this buffer spring 232 is sleeved on the outside of the corresponding guide post 211. One end of the buffer spring 232 is connected to the picking plate 21, and the other end is connected to the mounting plate 231. When the harvesting device operates, and the picking plate 21 vibrates relative to the mounting plate 231 and then relative to the frame 1, the guide post 211 moves axially within the connecting sleeve 233 to guide and limit the vibration displacement; simultaneously, the buffer spring 232 undergoes elastic deformation, absorbing vibration energy and effectively reducing impact, thereby achieving a buffering and protective effect on the harvesting mechanism 2.

[0072] In order to enable the mounting plate 231 to slide along the frame 1, such as Figure 2 As shown, a lower rail 11 and an upper rail 12, which are parallel to each other, are fixedly installed on the frame 1, as follows: Figure 18 , 19 As shown, a sliding pin 234 is fixedly installed on the mounting plate 231. The sliding pin 234 of the mounting plate 231 located on the lower side of the picking plate 21 is slidably installed in the lower rail 11, and the sliding pin 234 of the mounting plate 231 located on the upper side of the picking plate 21 is slidably installed in the upper rail 12. Through the dual guiding effect of the upper and lower rails, the mounting plate 231 is ensured to slide smoothly along the straight line of the frame 1, avoiding deviation.

[0073] like Figure 17-19 As shown, a drive motor 235 is fixedly mounted on the mounting plate 231 located below the picking plate 21, and a drive gear 236 is fixedly mounted on the output shaft of the drive motor 235, as shown. Figure 2 , 20 As shown, a rack 13 is fixed on the frame 1, such as Figure 18 As shown, the drive gear 236 can mesh with the rack 13 fixedly mounted on the frame 1. The rack 13 is parallel to the lower rail 11 and the upper rail 12. When the drive motor 235 starts, it drives the drive gear 236 to rotate. Since the rack 13 is fixed on the frame 1, the rotational motion of the drive gear 236 is converted into the linear movement of the lower mounting plate 231 along the lower rail 11, thereby pushing the picking plate 21 and its picking arm 22 to slide along the frame 1. When the picking plate 21 and the picking arm 22 move, they drive the upper mounting plate 231 to slide along the upper rail 12, ensuring the stability of the entire picking mechanism 2 moving along the frame 1. Of course, the mounting plate 231 can also be driven to slide along the lower rail 11 and the upper rail 12 by other conventional linear motion drive mechanisms.

[0074] like Figure 3As shown, in order to drive the picking plate 21 to vibrate relative to the mounting plate 231, a vibration driving mechanism 24 is provided on the picking plate 21, such as... Figure 4 As shown, the vibration drive mechanism 24 includes a protective shell 247 fixedly mounted on the picking plate 21, such as... Figure 21 As shown, a rotating shaft base 241 is fixedly installed on the picking plate 21 inside the protective shell 247. A rotating shaft 242 is rotatably mounted on the rotating shaft base 241. The rotating shaft 242 can rotate around its own central axis. An eccentric base block 243 is fixedly installed on the rotating shaft 242, and its center of mass does not coincide with the central axis of the rotating shaft 242, that is, the eccentric base block 243 is eccentrically set relative to the rotating shaft 242. The rotating shaft 242 is driven to rotate by a vibration drive motor 244 installed on the picking plate 21. In this embodiment, a transmission belt 245 is sleeved on the output end of the vibration drive motor 244 and the rotating shaft 242. When the vibration drive motor 244 starts, it drives the rotating shaft 242 to rotate through the transmission belt 245, thereby driving the eccentric base block 243 to rotate. It should be understood that, in addition to belt drive, the vibration drive motor 244 can also drive the rotating shaft 242 to rotate through conventional drive methods such as gear drive or direct connection with a coupling. In this embodiment, a motor base 246 is fixedly installed on the picking plate 21, and a vibration drive motor 244 is fixedly installed on the motor base 246.

[0075] When the eccentric block 243 rotates with the shaft 242, the periodic centrifugal force generated by the eccentric mass acts on the harvesting plate 21, thereby driving the harvesting plate 21 to vibrate continuously in the vertical direction. This vibration is further transmitted to the harvesting arm 22 connected to the harvesting plate 21, driving the harvesting arm 22 to carry out vibration harvesting operations on the sea buckthorn branches.

[0076] To reduce the overall weight of the harvesting device while maintaining structural strength, the harvesting plate 21 in this embodiment adopts a perforated design. To further ensure that sea buckthorn berries that have fallen off during vibration harvesting do not splash and scatter from the perforated area, such as... Figure 16 As shown, a solid harvesting baffle 25 is fixedly installed on the inner side of the harvesting board 21 (i.e., the side facing the sea buckthorn canopy). This harvesting baffle 25 can effectively prevent the fruit from splashing outward and guide it to the collection area below, thereby ensuring the fruit harvesting rate while achieving lightweighting.

[0077] To effectively cover the harvesting area of ​​the sea buckthorn canopy and adapt to its natural contours, the harvesting board 21 is designed with a semi-circular cross-section. Accordingly, as... Figure 17 As shown, the mounting plate 231 used to install and support the picking board 21 also adopts a matching semi-circular structure. The semi-circular design allows the picking board 21 to be close to the tree canopy with a larger wrapping surface, thereby expanding the effective range of vibration picking and ensuring that the fruiting branches are fully covered.

[0078] like Figure 1As shown, this embodiment includes two sets of harvesting mechanisms 2, which are symmetrically arranged about the central longitudinal axis of the frame 1, with the semi-circular openings of their respective harvesting plates 21 facing each other. This symmetrical layout design aims to simultaneously cover the sea buckthorn canopy from both sides, thereby expanding the operating range of a single harvest and ensuring that vibration energy can act on the branches on both sides of the canopy, effectively improving the fruit drop rate and harvesting efficiency.

[0079] To achieve relative rotation between the first tensioning arm 351 and the second tensioning arm 352, such as Figure 8 , 9 As shown in Figures 22 and 23, a first connecting seat 355 is fixedly installed at the end of the first tensioning arm 351, as follows: Figure 8 , 9 As shown in Figure 24, a second connecting seat 356 is fixedly installed at the corresponding end of the second tensioning arm 352. The second connecting seat 356 is rotatably mounted on the first connecting seat 355. Specifically, the second connecting seat 356 is rotatably fitted onto a bolt 357 fixed on the first connecting seat 355, so that the second tensioning arm 352 can rotate relative to the first tensioning arm 351 about the axis of the bolt 357, thereby realizing the opening or closing action between the two arms.

[0080] Furthermore, to enhance the structural stability of the rotating joint and limit unintended displacements, such as Figure 9 , 25 As shown, the first connecting seat 355 is provided with two first limiting blocks 3551 arranged parallel to each other, and a gap is formed between the two first limiting blocks 3551. Figure 9 , 26 As shown, the second connecting seat 356 is provided with a second limiting block 3561, which is inserted into the gap formed by the two first limiting blocks 3551, and forms an interlocking limiting structure with the two first limiting blocks 3551. Figure 9 As shown, the bolt 357 passes through both first limiting blocks 3551 and the second limiting block 3561 located between them, and is fixed to the first limiting block 3551. This limiting structure allows the second connecting seat 356 to rotate around the bolt 357 while effectively constraining its movement in other directions, ensuring transmission accuracy and reliability.

[0081] like Figure 10As shown, to secure the tension spring 353, a spring fixing bolt 358 is fixed to the first tension arm 351. The spring fixing bolt 358 passes through the interior of the first tension arm 351, and one end of the tension spring 353 is fixed to the spring fixing bolt 358 located inside the first tension arm 351, thereby achieving its installation and positioning at that end. One end of the spring connecting rope 354 is connected to the other end of the tension spring 353, and the other end of the spring connecting rope 354 passes through a rope hole 3552 opened on the first connecting seat 355 (shown in...). Figure 9 , 22 After passing through (23, 25), it is fixed on the second connecting seat 356 of the second tensioning arm 352, thereby realizing the power transmission and connection between the tensioning spring 353 and the second tensioning arm 352.

[0082] like Figure 6 , 7 As shown, the collection mechanism 3 also includes a collection conveyor belt 361, which is mounted on the collection frame 31 and located below the first elastic cloth 331. In this embodiment, both the first elastic cloth 331 and the second elastic cloth 332 are inclined, so that the collection conveyor belt 361 can receive and transport the sea buckthorn fruits that slide off the surfaces of the second elastic cloth 332 and the first elastic cloth 331. Conveyor belt baffles 362, fixed to the collection frame 31, are provided on both sides of the collection conveyor belt 361 to prevent the fruits from falling off the sides of the conveyor belt during transport. A conveyor belt motor 363 (shown in the figure) is fixed on the collection frame 31. Figure 7 The motor (in the middle) is connected to the collection conveyor belt 361 at its output end, driving the collection conveyor belt 361 to operate continuously and transport the collected sea buckthorn berries. Connecting the motor to the collection conveyor belt to drive its operation is a conventional technique. A collection box 364 is located below the end of the collection conveyor belt 361 to collect and temporarily store the sea buckthorn berries transported by the collection conveyor belt 361.

[0083] Regarding the specific fixing method between the second elastic fabric 332 and the support rod 341, such as Figure 7 , 27 As shown, a support plate 342 is fixedly installed at each end of the support rod 341, and the second elastic cloth 332 is fixedly installed between the two support plates 342.

[0084] In this embodiment, the second elastic cloth 332 has higher elasticity than the first elastic cloth 331, exhibiting superior deformation capability. The second elastic cloth 332, with its higher elasticity (relative to the first elastic cloth 331), is positioned at the front end of the collecting mechanism 3 (i.e., the end closest to the sea buckthorn tree), allowing it to adapt and deform upon contact with the lower branches of the sea buckthorn tree. This effectively avoids interference with the branches and reduces disturbance to the tree. By employing a combination of fabrics with different elastic properties, the first elastic cloth 331 and the second elastic cloth 332 together form a buffer collecting surface, significantly reducing impact damage from falling sea buckthorn berries. The second elastic cloth 332, positioned at the front end, is responsible for wrapping and receiving the berries, while the first elastic cloth 331 connects to it, expanding the collecting area and ensuring the structural stability and smooth operation of the entire collecting cloth system even when a large number of berries fall. Furthermore, the higher elasticity of the second elastic cloth 332 allows it to wrap the sea buckthorn branches through elastic deformation without significantly affecting the original spatial position of the lower branches of the sea buckthorn tree, thus achieving efficient collection while minimizing disturbance to the tree.

[0085] like Figure 1 As shown, this embodiment includes two sets of collection mechanisms 3, symmetrically arranged about the central longitudinal axis of the frame 1 and located directly below the two sets of harvesting mechanisms 2. The two sets of collection mechanisms 3 are structurally identical, each including an independent collection frame 31, a first elastic cloth 331, a second elastic cloth 332, and a tensioning component 35. Driven by the tensioning component 35, the second elastic cloths 332 on both sides extend synchronously towards the sea buckthorn canopy, eventually bringing their front edges together or in contact, thus forming a continuous and complete annular wrapping structure around the lower branches of the sea buckthorn tree. The design of the two sets of collection mechanisms 3 completely encloses the fruiting branches of the sea buckthorn tree, ensuring that the sea buckthorn fruits that fall due to vibration can be effectively collected by the collection mechanisms 3, significantly improving the fruit collection efficiency.

[0086] To adapt the harvesting equipment to harvesting sea buckthorn trees of different heights, such as... Figure 1 As shown, the harvesting device also includes a lifting mechanism 4 located below the collecting mechanism 3. The lifting mechanism 4 includes a lifting frame 41 that can be placed on a working surface (such as the ground). A hydraulic cylinder 42 is fixedly installed on the lifting frame 41. The telescopic end of the hydraulic cylinder 42 is fixedly connected to the bottom of the collecting frame 31 of the collecting mechanism 3. A guide sleeve 411 is fixedly installed on the lifting frame 41. Figure 6 , 7As shown, a guide rod 311 is fixed to the bottom of the collection frame 31, and the guide rod 311 is slidably inserted into the guide sleeve 411. When the harvesting height needs to be adjusted, the hydraulic cylinder 42 is activated, and its telescopic end pushes or pulls the collection frame 31 to move vertically. During this process, the guide rod 311 moves synchronously with the collection frame 31 and slides within the guide sleeve 411. This guiding structure can prevent the harvesting device from deflecting during the lifting and lowering process, ensuring the linearity and stability of the lifting and lowering movement. By controlling the telescopic stroke of the hydraulic cylinder 42, the working height of the overall harvesting device can be adjusted, thereby adapting to sea buckthorn trees of different heights due to differences in planting environment, significantly expanding the applicability and harvesting flexibility of the device.

[0087] Furthermore, such as Figure 1 As shown, two sea buckthorn branch gathering plates 14 are fixedly installed on the frame 1. These two plates 14 are symmetrically arranged and form an opening on the side facing the sea buckthorn tree. As the frame 1 moves towards the sea buckthorn tree and gradually enters the harvesting device, the sea buckthorn branch gathering plates 14 guide and gather the branches, concentrating them in the harvesting area and preventing them from scattering outside the device. When the frame 1 moves to the side of the sea buckthorn tree, its position needs to be adjusted so that the opening formed by the two plates 14 aligns with the branches to be harvested, ensuring that most of the branches are effectively gathered and guided into the device, providing favorable conditions for subsequent vibratory harvesting operations.

[0088] In this embodiment, the vibrating seabuckthorn harvesting device moves to the front of the seabuckthorn tree and slowly advances until the opening on the frame 1 is aligned with the tree. The seabuckthorn branch gathering plate 14, located at the front of the frame 1, guides and gathers the branches as the canopy enters, concentrating them into the harvesting area. When the frame 1 is positioned directly above the seabuckthorn tree, the device brakes and stops. At this point, both the collecting mechanism 3 and the picking mechanism 2 are in their initial gathered state, located on the outermost side of the overall device.

[0089] After the device comes to a complete stop, the collecting mechanism 3 begins to operate. The electric roller 32 starts, releasing the first elastic cloth 331 wound around it. At this time, the tension spring 353, which is in a stretched state, pulls the second tension arm 352 through the spring connecting rope 354, causing the angle between the first tension arm 351 and the second tension arm 352 to gradually increase, and the two arms open outward and tend to straighten. During this process, the first tension arm 351 pushes the support rod 341 to move towards the sea buckthorn branch, thereby pulling the first elastic cloth 331 to unfold and gradually tighten. As the first elastic cloth 331 unfolds, the second elastic cloth 332, which is fixedly connected to it through the support rod 341, also moves towards the sea buckthorn branch until it contacts the surface of the branch. The second elastic cloth 332 undergoes elastic deformation under the obstruction of the branch, bending and wrapping around the branch to form a tightly fitting wrapping receiving surface. When the second elastic cloths 332 on both sides completely wrap the lower branches of the sea buckthorn tree, forming a continuous and complete ring-shaped wrapping structure, the electric roller 32 stops rotating, the conveyor belt motor 363 starts, and drives the collection conveyor belt 361 to start running.

[0090] After the collecting mechanism 3 is in place, the harvesting mechanism 2 begins the harvesting operation. The drive motor 235 starts, and through the meshing transmission of the drive gear 236 and the rack 13, it drives the mounting plate 231 to slide along the lower track 11 and the upper track 12, thereby moving the entire harvesting mechanism 2 towards the sea buckthorn canopy. The multiple harvesting arms 22 located on the harvesting plate 21 then move closer to the center. During the movement, the U-shaped harvesting heads 222 at the front end of the harvesting arms 22 begin to contact the sea buckthorn branches, and the harvesting head rollers 223 rotatably mounted on the U-shaped harvesting heads 222 clamp the sea buckthorn branches.

[0091] Once the picking arm 22 clamps the branch, the vibration drive mechanism 24 begins to operate. The vibration drive motor 244 drives the rotating shaft 242 to rotate via the transmission belt 245. The eccentric block 243 fixed on the rotating shaft 242 generates a periodic centrifugal force due to its eccentric mass. This centrifugal force acts directly on the picking plate 21, driving the picking plate 21 to vibrate continuously in the vertical direction relative to the mounting plate 231. The vibration of the picking plate 21 is directly transmitted to the picking arm 22 fixed on it, which in turn drives the clamped seabuckthorn branch to vibrate synchronously. When the inertial force generated by the vibration is greater than the binding force between the fruit stalk and the branch, the seabuckthorn fruit is continuously shaken off. When the picking plate 21 vibrates relative to the mounting plate 231, the guide column 211 moves axially within the connecting sleeve 233 to guide and limit the vibration displacement; at the same time, the buffer spring 232 undergoes elastic deformation to absorb vibration energy, effectively reducing impact and achieving buffering and protection for the picking mechanism 2.

[0092] The shaken-off fruits fall onto the surfaces of the unfolded second elastic cloth 332 and the first elastic cloth 331, and slide downwards along the inclined cloth surface. The collection conveyor belt 361 catches the fruits that slide off the cloth surface and, under the protection of the conveyor belt baffle 362, transports the fruits to the collection box 364 at the end, completing the collection and storage of the fruits.

[0093] During the vibratory harvesting process, as the fruits near the U-shaped picking head 222 are shaken off, the drive motor 235 can be restarted to drive the picking mechanism 2 to continue moving. Since both the picking arm 22 and the branch have a certain degree of elasticity, the picking arm 22 can slide along the branch to the area of ​​the unshaken fruits during the movement, and continue to carry out vibratory harvesting to ensure a high harvest rate.

[0094] For sea buckthorn branches at higher positions, the harvesting height can be adjusted via the lifting mechanism 4 after a single harvesting operation. The hydraulic cylinder 42 is activated, pushing the collection frame 31 vertically, thereby raising the overall height of the harvesting device. During the lifting process, the guide rod 311 slides within the guide sleeve 411 to ensure stability. After adjusting to a suitable height, the harvesting process is repeated to achieve adaptive harvesting for sea buckthorn trees of different heights.

[0095] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
