Description

Technical Field

[0001] The utility model relates to the technical field of mechanical picking, and more specifically, to a walnut harvesting energy storage and shaking device. Background Art

[0002] Currently, walnut cultivation can be roughly divided into two categories: dwarfed, densely planted walnut orchards and traditionally cultivated walnut trees. While dwarfed, densely planted walnut orchards can utilize large harvesting equipment, traditionally cultivated walnut trees in Yunnan's mountainous regions, due to their complex growing environment and tall trees, are difficult to access with large equipment. Harvesting relies on lightweight handheld equipment or manual tree climbing.

[0003] Due to the complex growing environment and towering size of walnut trees in Yunnan's mountains, existing harvesting techniques face numerous challenges. First, the unpruned, towering walnut trees in Yunnan's mountains make it difficult for existing lightweight harvesting equipment to fully reach the trees, often requiring climbing the trees to harvest, which poses a significant safety risk. Furthermore, existing harvesting methods primarily rely on manual tree climbing, which is not only inefficient but also highly dangerous. Harvesting operations are particularly difficult in mountainous environments, and as the labor force shrinks, fewer and fewer people are willing to undertake this high-intensity, high-risk harvesting task.

[0004] Furthermore, the complex mountainous environment makes access difficult for large machinery, and lightweight equipment lacks the power and structural design to effectively handle the complex terrain. Rope-hanging operations often require manual climbing, further increasing operational risks. Existing lightweight equipment lacks sufficient energy during the shaking process, making it difficult to effectively shake the thick branches of tall trees, resulting in low harvesting efficiency and increased labor and time requirements.

In the specification and claims of the present invention and the above-mentioned drawings, when an element is referred to as being "fixed on" or "mounted on" or "disposed on" or "connected to" another element, it may be directly or indirectly located on the other element. For example, when an element is referred to as being "connected to" another element, it may be directly or indirectly connected to the other element.

[0035] In addition, references to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0036] It is understood explicitly and implicitly by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] See Figure 1 As shown, the utility model also provides a walnut harvesting energy storage shaking device, including a split power unit 1, an energy storage shaking mechanism 2, a fixed support mechanism 3 and a hanging rope mechanism 4, and a shaking unit 5, and the split power unit 1, the energy storage shaking mechanism 2 and the hanging rope mechanism 4 are respectively provided on the fixed support mechanism 3.

[0038] The hanging rope mechanism 4 drives the shaking unit 5 to be hung on a high branch, and the shaking unit 5 is connected to the energy storage shaking mechanism 2; the split power unit 1 drives the energy storage shaking mechanism 2 to move, driving the shaking unit 5 to shake the high branches of the walnut tree, causing the fruits to fall off.

[0039] Specifically, the shaking device adopts a modular design as a whole, that is, the split power unit 1, the energy storage shaking mechanism 2, the fixed support mechanism 3 and the hanging rope mechanism 4 are independent mechanisms respectively, which are suitable for complex mountain terrain and can be quickly assembled and disassembled, greatly improving the walnut harvesting efficiency.

[0040] As attached Figure 2 As shown, the fixed support mechanism 3 includes a fixed drill bit 31, a drill bit slide 32, a frame body 34, and support assemblies (35, 36). The drill bit slide 32 is provided on the side of the frame body 34. The fixed drill bit 31 is arranged longitudinally and slides with the drill bit slide 32 to serve as a fixing device during shaking operation. The bottom end of the frame body 34 is provided with a support assembly to support the frame body 34 and facilitate the movement and positioning of the entire device.

[0041] In some embodiments, the support assembly includes support columns 35 and support wheels 36, which are disposed on opposite sides of the bottom end of the frame body 34. The support wheels 36 drive the entire device to move, and after the device is moved to a suitable position, the support columns 35 support the entire device to prevent the device from moving due to uneven terrain during operation, which could affect the device's reliability.

[0042] Specifically, based on the forward direction of the device, the support wheels 36 are located at the front end of the frame body 34, and the support posts 35 are located at the rear end of the frame body 34. The diameter of the support wheels 36 is greater than the height of the support posts 35, causing the frame body 34 to tilt from the front end to the rear end. The fixed drill bit 31 and the drill rail 32 are both located at the rear end of the frame body 34 to prevent interference with the support wheels 34. The axial direction of the fixed drill bit 31 is perpendicular to the forward direction. It is understood that the support posts 35 and support wheels 36 are arranged in two symmetrical groups, and their number and installation position can be adjusted according to actual needs.

[0043] When the device needs to move forward, the rear end of the frame body 34 can be lifted to lift the support column 35 off the ground. The support wheel 36 at the front end of the frame body 34 can then drive the entire device to move. Move to the appropriate position, lower the rear end of the frame body 34, and adjust the fixed drill bit 31 so that it slides up and down along the drill bit slide rail 32 and drills into the ground. The fixed drill bit 31 can drill into the ground up to 50 cm. Drilling into the ground ensures that the device remains stable during the shaking operation, avoids equipment shaking and vibration force dispersion caused by uneven terrain, and ensures that the vibration force is effectively transmitted to the tree branches. It also solves the problem of self-vibration caused by insufficient dead weight of small devices. Small devices usually vibrate themselves rather than the target when shaking, which reduces the energy transfer efficiency. This embodiment ensures that the vibration force is effectively transmitted to the target tree branches through sufficient dead weight and a fixed drill bit 31.

[0044] In one embodiment, a handrail 33 is provided on the frame body 34 to facilitate the movement of the entire device by dragging the device with the handrail 33 when the device needs to be moved a short distance. Specifically, the handrail 33 is provided on the side of the rear end of the frame body 34 and on the outer periphery of the drill slide 32, making it convenient to lift the rear end of the frame body 34 and push the frame body 34 to move.

[0045] In one embodiment, the frame body 34 is made of lightweight aluminum material, which has the advantage of being light in weight and convenient for mountain transportation.

[0046] It can be understood that the fixed drill bit 31 is connected to the power source, and the fixed drill bit 31 can be translated along the drill bit slide rail 32 under the action of the power source. In order to reduce the overall weight of the device, the fixed drill bit 31 is also connected to the split power mechanism 1.

[0047] As attached Figure 3 As shown, the split power mechanism 1 includes a power unit 11 , a transmission connection plate 13 and a frame slide rail 15 respectively arranged on the fixed support mechanism 3 , and a power connection plate 12 and a power unit slide rail 14 are provided on the power unit 11 .

[0048] The power unit 11 can use a 5.5kw diesel engine to provide power for the entire device. The power unit 11 is connected via a power connection plate 12 and a transmission connection plate 13, and can transmit power to the frame body 34 of the fixed support mechanism 3, and then to the energy storage and shaking mechanism 2, thereby achieving efficient power transmission. A power unit slide rail 14 is also provided on the power unit 11, and a frame slide rail 15 is connected to the frame body 34 of the fixed support mechanism 3. The power unit 11 is quickly connected to the frame slide rail 15 via the power unit slide rail 14, ensuring that the split power mechanism 1 can be securely connected and quickly assembled. The power unit slide rail 14 can also cooperate with the frame slide rail 15 to achieve fine-tuning of the split power mechanism 1 on the frame body 34.

[0049] Specifically, the transmission connecting plate 13 and the drill slide 32 are located on opposite sides of the frame body 34. The power unit 11 is connected and matched with the transmission connecting plate 13, which can save installation space and transmit power from the front end to the rear end of the device, ensuring the reliability of the overall operation of the device.

[0050] As attached Figure 4 As shown, the energy storage shaking mechanism 2 includes a half-tooth transmission wheel 21, a shaking rack 22, an angle adjustment slide rail 23, an energy storage spring 24, and a rope connector 25;

[0051] The semi-toothed transmission wheel 21 is arranged on the frame body 34, and power transmission is realized between the semi-toothed transmission wheel 21 and the transmission connecting plate 13 through a connecting piece (not shown in the figure). The angle adjustment slide rail 23 is arranged on the frame body 34 and is located on one side of the semi-toothed transmission wheel 21. The shaking rack 22 is arranged on the angle adjustment slide rail 23, and the shaking rack 22 slides with the angle adjustment slide rail 23. The semi-toothed transmission wheel 21 and the shaking rack 22 are respectively partially provided with mutually meshing serrations, and the two cooperate to store energy and release it to drive the shaking action. The shaking rack 22 is also provided with an energy storage spring 24 for realizing shaking, and the end of the shaking rack 22 is provided with a rope connector 25, and the rope connector 25 is used to be connected to the hanging rope mechanism 4 for transmitting shaking energy.

[0052] In one embodiment, the outer circumference of the semi-toothed transmission wheel 21 is provided with first serrations 211, while the remaining outer circumference is a smooth surface 212. The rocking rack 22 is provided with second serrations 221 along its length. Rotation of the semi-toothed transmission wheel 21 causes the first serrations 211 and the second serrations 221 to mesh and transmit power, thereby causing the rocking rack 22 to translate along its axial direction.

[0053] In one embodiment, the energy storage spring 24 and the second serration 221 are arranged in sequence along the axial direction of the rocking rack 22. The energy storage spring 24 is sleeved on the outer periphery of the rocking rack 22 and is located between the end of the rocking rack 22 and the corresponding side of the angle adjustment slide rail 23. The rope connector 25 is arranged on the end of the rocking rack 22 away from the second serration 221.

[0054] To facilitate the coordination between the semi-toothed transmission wheel 21 and the rocking rack 22, and to ensure the reliable operation of the energy storage spring 24, the outer half of the semi-toothed transmission wheel 21 is provided with a first serration 211, while the remaining half is a smooth surface 212. The middle portion of the rocking rack 22 is located on the angle adjustment rail 23, with the second serration 221 and the energy storage spring 24 respectively located on either side of the angle adjustment rail 23.

[0055] Specifically, the power of the split power unit 1 is transmitted to the energy storage and shaking mechanism 2 through the connecting piece on the frame body 34, driving the half-tooth transmission wheel 21 to rotate, and the first sawtooth 211 and the second sawtooth 221 are meshed and transmitted, driving the shaking rack 22 to translate along the axial direction. After the meshing stroke of the first sawtooth 211 and the second sawtooth 221 is completed, since the two ends of the energy storage spring 24 are respectively connected to the shaking rack 22 and the angle adjustment slide rail 23, the energy storage spring 24 is in a compressed state to store energy, such as Figure 5 As shown in (a), the half-toothed transmission wheel 21 continues to rotate, the energy storage spring 24 releases energy, and the smooth surface 212 of the half-toothed transmission wheel 21 and the shaking rack 22 slide together. Figure 5 As shown in (b), the tree branches are shaken. The energy storage spring 24 accumulates energy when the half-toothed transmission wheel 21 and the shaking rack 22 are engaged, and quickly releases the energy to enhance the shaking force when the half-toothed transmission wheel 21 and the shaking rack 22 are slidably matched.

[0056] In one embodiment, the end of the angle-adjustable slide rail 23 slides on the shaking rack 22 to achieve deflection movement. The adjustment angle range of the angle-adjustable slide rail 23 is between 30° and 90°, and the specific value can be 30°, 45°, 60°, 75°, 90° or any value within the range. It can be adjusted according to the different heights and angles of the branches to ensure that the energy of the shaking device can be efficiently transferred to the branches.

[0057] In one embodiment, a buffer spring 26 is provided on the rocking rack 22 to reduce damage to the energy storage rocking device caused by the hard impact of the energy storage spring 24 when the energy storage spring 24 releases energy. As will be appreciated, one end of the buffer spring 26 is disposed on the rocking rack 22, and the other end of the buffer spring 26 is disposed on the frame body 34, thereby reliably providing a buffering effect and ensuring the overall operational reliability of the device.

[0058] Specifically, the half-tooth transmission wheel 21 and the shaking rack 22 cooperate with each other to store energy and release it to drive the shaking action. Every time the half-tooth transmission wheel 21 rotates one circle, the shaking rack 22 completes a forward and backward translation and compresses the energy storage spring to complete an energy storage and release cycle. The maximum operating frequency of the energy storage shaking mechanism 2 can reach 10Hz to adapt to the common frequency of tree picking.

[0059] As attached Figure 6 and Figure 7 As shown, the hanging rope mechanism 4 includes a base 41, a protective shell 42, a signal receiver 43, a drone 44, and a rope buckle 45; the shaking unit 5 includes a rope buckle connector 51, a traction rope 52, and a shaking bag 53.

[0060] A base 41 is mounted on the frame body 34 of the fixed support mechanism 3. A protective shell 42 is movably mounted on the base 41. A drone 44 is mounted on the base 41 and positioned within the protective shell 42. A rope-clip 45 is provided on the drone 44, which connects to a rope-clip connector 51. The release of the rope-clip connector 51 is accomplished via wireless signals. The rope-clip connector 51 is connected to a traction rope 52, which in turn is connected to a vibration bag 53. The vibration bag 53 is then mounted and connected to the rope connector 25.

[0061] Specifically, during the movement and transportation of the entire device, the protective shell 42 is in a closed state to prevent the drone 44 from being bumped by the external environment or accidentally falling, ensuring that the drone 44 is in good condition before use.

[0062] As can be understood, the head of the traction rope 52 is provided with a light counterweight to ensure that the traction rope 52 can fall vertically to the ground under the weight of the light counterweight when the drone 44 releases the traction rope 52. The head counterweight is connected to the rope buckle 45 at the bottom of the drone 44 and can release the traction rope 47 after receiving a wireless signal. Since the tail end of the traction rope 47 is connected to the shaking bag 48, after the traction rope 47 falls to the ground, the shaking bag 48 can be hung on the target branch of the walnut tree, and the shaking bag 48 is connected to the energy storage shaking mechanism 2 to achieve the effect of energy storage shaking of the walnut tree.

[0063] As can be understood, the split power mechanism 1, the energy storage and vibration mechanism 2, and the fixed support mechanism 3 are mechanically connected via quick-connect buckles to improve connection speed and reliability in mountainous environments. Power transmission between the power unit 11 and the energy storage and vibration mechanism 2 is achieved through a coupling for rapid engagement. The hanging rope mechanism 4 can be magnetically attached to the front end of the fixed support mechanism 3, facilitating overall movement and quick disassembly.

[0064] See Figure 8As shown, the walnut harvesting energy storage shaking device provided by the utility model is actually used in the process of harvesting walnuts on high branches as follows:

[0065] S1. According to different mountain angles, tree heights, and ground space, the walnut harvesting energy storage and shaking device is reasonably placed, and the split power mechanism 1, energy storage and shaking mechanism 2, fixed support mechanism 3 and drone hanging rope mechanism 4 are installed into one body. The angle of the fixed support mechanism 3 is adjusted so that it is facing the branch to be picked.

[0066] S2. After the position of the frame body 34 is stabilized, the split power unit 1 is started to transmit power to the fixed drill bit 31, driving the fixed drill bit 31 to drill into the mountain soil, thereby completing the fixing of the entire device.

[0067] S3. Adjust the angle of the angle-adjusting slide rail 23 in the energy storage shaking mechanism 2 so that the rope connector 25 at the end of the shaking rack 22 is facing the branch to be shaken, completing the preparation action of the device.

[0068] S4. The opening signal is transmitted to the signal receiver 43, the protective shell 42 is controlled to open, the UAV 44 is ready for take-off, and the rope clip 45 is connected to the rope clip connector 51.

[0069] S5. After receiving the take-off command, the drone 44 carries the rope connector 51 and the traction rope 52 and flies to the top of the target branch. During this process, the flight position of the drone 44 is precisely controlled to ensure that the traction rope 52 can pass through the target branch smoothly.

[0070] S6. After arriving at the designated location, the drone 44 is triggered by a wireless signal to release the rope clip 45. At this time, the rope clip connector 46 naturally falls to the ground under the action of gravity. When the rope clip connector 51 lands, the drone 44 returns to the base 41 and waits for the next take-off command.

[0071] S7. After the rope connector 51 is lowered, the tail of the traction rope 52 is connected to the shaking bag 53. By pulling the traction rope 52, the shaking bag 53 passes over the target branch and is successfully mounted.

[0072] S8, the power unit 11 drives the half-tooth transmission wheel 21 to rotate through the power connecting plate 12 and the transmission connecting plate 13 in turn, and the half-tooth transmission wheel 21 and the rocking rack 22 are engaged and transmitted, and the rocking rack 22 translates to compress the energy storage spring 24 to store energy.

[0073] S9, after the meshing stroke between the half-tooth transmission wheel 21 and the shaking rack 22 is completed, the half-tooth transmission wheel 21 and the shaking rack 22 slide together, the energy storage spring 24 releases energy to shake, and drives the high branches to shake through the shaking bag 53, completing a shaking picking operation.

[0074] The above harvesting process completes the high-altitude rope hanging task through the precise operation of the drone, avoiding the risks of traditional manual tree climbing and greatly improving the safety and efficiency of the harvesting process.

[0075] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
