Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a tying-type walnut harvesting machine. Background Technology

[0002] Walnuts are widely cultivated in my country. Yunnan Province ranks first in the country in terms of walnut planting area, output, and output value. As of the end of 2021, the walnut planting area in Yunnan Province reached 43 million mu, which remained basically stable. The output was 1.6 million tons and the comprehensive output value was 45.1 billion yuan, making a positive contribution to the economic development of the province.

[0003] The following problems currently exist in walnut production: First, walnut production costs are increasing, with labor costs rising year by year; harvesting costs alone account for more than 50% of the total production cost. Second, the comparative benefits of walnut production are declining; in recent years, compared to some cash crops, the comparative benefits of walnut cultivation have been relatively poor, affecting farmers' enthusiasm for planting, managing, and harvesting walnuts. Third, the aging workforce leads to labor shortages during the walnut production and harvesting seasons, hindering the stable and efficient development of Yunnan's walnut industry. Promoting mechanization in walnut harvesting and reducing production costs is of great significance for promoting the development of the walnut industry and increasing farmers' income.

[0004] Currently, walnut production faces several key constraints. Walnut prices remain low, leading many farmers to adopt extensive management methods, or even abandon harvesting altogether due to high costs. Walnut cultivation conditions are complex; most walnuts grow in steep mountainous areas lacking basic access roads, making it difficult for large machinery to enter. Scattered planting areas with low levels of centralization make unified and scientific management difficult. The complex tree structure, with its height and large trunk diameter, makes harvesting challenging, hindering the application and promotion of traditional agricultural machinery in walnut orchards, while manual harvesting presents safety concerns. Therefore, the research and development and promotion of lightweight, compact, reliable, and easy-to-operate portable walnut harvesting equipment is urgently needed.

[0005] In view of this, it is necessary to propose a tying walnut harvesting machine to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0034] Please see the appendix Figures 1 to 6 A walnut harvesting machine with binding mechanism provided in one embodiment of the present invention includes a drive component 10, a vibration component 20, and a binding component 30 for binding the tree trunk; wherein, the binding component 30 includes a connecting seat 310 and a clamp component (not shown in the figure), the connecting seat 310 is connected to the vibration component 20, the clamp component is connected to the connecting seat 310 and is used to bind the tree trunk, and the drive component 10 drives the vibration component 20 to vibrate, so as to shake the walnuts off the walnut tree.

[0035] Specifically, this application uses the drive component 10 to drive the vibration component 20 to generate vibration, which can efficiently shake the walnuts off the walnut tree. Compared with manual harvesting, this method can significantly improve harvesting efficiency and save labor and time costs. The binding component 30 can be stably fixed to the trunk, ensuring the stability of the machine during harvesting, preventing the walnuts from falling off or shifting due to vibration, and also allowing the vibration energy to be more concentratedly transmitted to the walnut tree, improving the harvesting effect. Since the clamp component can be flexibly adjusted to adapt to trunks of different diameters, it has high applicability. The operator only needs to fix the binding component 30 to the trunk and start the drive component 10 to begin the harvesting work, greatly reducing the difficulty and complexity of operation.

[0036] In a preferred embodiment, the drive assembly 10 includes a gasoline engine assembly 110 and a mechanical flexible shaft 120. One end of the mechanical flexible shaft 120 is connected to the output end of the gasoline engine assembly 110, and the other end is connected to the input end 240 of the vibration assembly.

[0037] Specifically, the gasoline engine assembly 110 serves as a power source, providing stable and robust power output; the mechanical flexible shaft 120 effectively transmits the power generated by the gasoline engine assembly 110 to the vibration assembly 20, enabling the vibration assembly 20 to continuously and stably generate vibration, thereby effectively shaking the walnuts off the walnut tree. The mechanical flexible shaft 120 is flexible and elastic, adaptable to force transmission requirements at different angles and distances, and has good applicability.

[0038] Furthermore, it also includes a frame-type main frame assembly 40, on which both the gasoline engine assembly 110 and the vibration assembly 20 are mounted.

[0039] The main frame assembly 40 in this embodiment adopts a frame design, which has good structural stability and load-bearing capacity, and is conducive to improving the working efficiency and stability of the equipment.

[0040] It should be noted that this utility model connects the gasoline engine assembly 110 and the vibration assembly 20 together via a mechanical flexible shaft 120. The gasoline engine assembly 110 and the vibration assembly 20 can be fixed to the main frame for use, or they can be detached from the main frame assembly 40 for use. When used alone, the vibration assembly 20 is tied to the trunk or branch of the tree, and then the mechanical flexible shaft 120 is connected. Starting the gasoline engine assembly 110 can also achieve harvesting operations.

[0041] In a preferred embodiment, the vibration assembly 20 includes a vibration head 210, a flip base 220, and a rotating shaft 230. The vibration head 210 is connected to the bottom of the flip base 220, the flip base 220 is located on the top of the main frame assembly 40, the flip base 220 is connected to the rotating shaft 230 and moves synchronously with the rotating shaft 230, and the rotating shaft 230 is rotatably connected to the top of the main frame assembly 40.

[0042] Specifically, the connection between the flip-up base 220 and the rotating shaft 230 allows the vibration component 20 to adjust its vibration angle within a certain range. The position and angle of the vibration head 210 can be adjusted according to the actual conditions of different walnut trees to ensure the harvesting effect.

[0043] It is worth noting that the vibrating head 210 of this application can employ mature devices such as flexible shaft insertion vibrators and planetary insertion vibrators from the prior art. In a preferred embodiment, the vibrating head 210 is as follows: Figure 5-6As shown, the vibrating head 210 includes an input end of the vibrating head adapted to the mechanical flexible shaft 120, a first gear 213, a second gear 214, and a third gear 215. An eccentric block 216 is provided on the end face of the third gear 215. The mechanical flexible shaft 120 drives the first gear 213 to rotate, and the first gear 213 drives the third gear 215 to rotate, thereby driving the eccentric block 216 to rotate and generating vibration. Furthermore, there are two third gears 215 and two second gears 214. The two second gears 214 mesh, which can realize the synchronous movement of the two first gears 213. Each third gear 215 is provided with an eccentric block 216. The position of the eccentric block is adaptively set to generate the corresponding vibration, which will not be elaborated here.

[0044] In a preferred embodiment, the bottom of the vibrating head 210 is provided with a first connecting plate 211, the first connecting plate 211 having a first connecting hole 212 for bolts to pass through, and the flipping base 220 having second connecting holes 221 spaced apart along its own extension direction. The vibrating head 210 is connected to the flipping base 220 by bolts passing through the first connecting hole 212 and the second connecting hole 221.

[0045] By bolting through the connection holes on the first connecting plate 211 and the flipping base 220, a stable connection between the vibrating head 210 and the flipping base 220 is achieved.

[0046] like Figure 2 As shown, the first connecting plate 211 has a first connecting hole 212, while the flipping base 220 has multiple second connecting holes 221 spaced apart along its own extension direction. This design allows the position of the vibrating head 210 on the flipping base 220 to be adjusted, and the height of the vibrating head 210 can be adjusted according to the height at which the tree trunk can be clamped. Combined with the rotation of the flipping base 220, the harvesting height and harvesting angle can be adjusted, improving adaptability. At the same time, the bolted connection method makes the installation and disassembly process simpler and faster.

[0047] In a preferred embodiment, the system further includes a tree-pairing assembly 50 connected to the front end of the main frame assembly 40. The tree-pairing assembly 50 includes a second connecting plate 510 and an arc-shaped docking plate 520 with an opening away from the main frame assembly 40. The second connecting plate 510 is connected to the front end of the main frame assembly 40, and the arc-shaped docking plate 520 is connected to the second connecting plate 510. The arc-shaped docking plate 520 matches the shape of the tree trunk, and each end of the arc-shaped docking plate 520 has a rope hole 530 for ropes to pass through.

[0048] Specifically, the arc-shaped connecting plate 520 of the tree assembly 50 is designed to fit closely to the shape of the tree trunk. This design not only increases the contact area between the harvester and the tree trunk, improving stability during harvesting, but also more effectively transmits vibration energy. The arc-shaped connecting plate 520 is connected to the front end of the main frame assembly 40 via the second connecting plate 510, forming a stable support structure. The arc-shaped connecting plate 520 is aligned with the tree trunk, and the structure is secured to the trunk with ropes through the rope holes 530 to prevent the main frame assembly 40 from slipping.

[0049] In a preferred embodiment, the clamp assembly includes two clamp units 320 spaced apart along the length of the vibrating head 210. Each clamp unit 320 includes a first arc plate 321, a second arc plate 322, and a screw 323. The first arc plate 321 and the second arc plate 322 are arranged opposite to each other. The first arc plate 321 has a first through hole through which the screw 323 passes. The second arc plate 322 has a second through hole corresponding to the first through hole. The screw 323 has a first nut 324 screwed on the outside of the first arc plate 321 and a second nut 325 screwed on the outside of the second arc plate 322.

[0050] Specifically, the clamp assembly consists of two clamp units 320 spaced apart along the length of the vibrating head 210. Each clamp unit 320 is further composed of a first arc-shaped plate 321 and a second arc-shaped plate 322 positioned opposite each other and secured by a screw 323, a first nut 324, and a second nut 325. The clamp assembly can be tightly fixed to the tree trunk, preventing the harvester from shaking or falling off during vibration, thus improving the stability and safety of harvesting. Since the clamp unit 320 consists of two arc-shaped plates, it can adapt to tree trunks or parts of different diameters. By adjusting the position of the first nut 324 and the second nut 325 on the screw 323, the tightness of the clamp unit 320 can be easily adjusted to ensure a tight fit to tree trunks of different sizes, enhancing the adaptability and flexibility of the harvester. The installation and disassembly of the clamp assembly is relatively simple. Simply place the first arc-shaped plate 321 and the second arc-shaped plate 322 around the tree trunk, then pass the screw 323 through the corresponding through hole and screw the nut on the outside. This design not only saves installation time but also facilitates disassembly and maintenance when needed. The curved plate, screw 323, and nut design of the clamp assembly can reduce the pressure points on the trunk to a certain extent, avoiding direct damage to the trunk. This design helps protect the health of the trunk and reduces potential damage to trees caused by harvesting operations.

[0051] Furthermore, the bottom of the main frame assembly 40 is provided with casters 410. The design of the casters 410 allows the entire harvester to move easily on the ground, greatly increasing the harvester's range of use and enabling it to adapt to various complex working environments.

[0052] Furthermore, the main frame assembly 40 is connected to a pusher 60 at the end away from the tree-pairing assembly 50. The pusher 60 is designed to allow the operator to easily push or pull the harvester for movement and positioning. This design greatly reduces the operator's physical burden and improves the efficiency of harvesting operations.

[0053] Furthermore, the assembly also includes a first bearing seat 420 and a second bearing seat 430 disposed opposite to each other on both sides of the main frame assembly 40, with the rotating shaft 230 rotatably connected between the first bearing seat 420 and the second bearing seat 430. The first bearing seat 420 and the second bearing seat 430, disposed opposite to each other on both sides of the main frame assembly 40, provide stable support for the rotating shaft 230. This design ensures that the rotating shaft 230 remains smooth during rotation, reducing swaying and offset caused by vibration or external forces.

[0054] Workflow: Pull or push the walnut harvester to the tree trunk, align the tree alignment component 50 with the trunk, and secure the harvester to the trunk with a rope through the rope hole 530 to prevent the harvester from slipping. Next, raise the vibrating head 210 by flipping the base frame 220, align the vibrating head 210 with the trunk or branch, and secure it tightly to the trunk using the clamp unit 320. Then, start the gasoline engine assembly 110 to increase its speed to complete the vibration operation. Preferably, the gasoline engine assembly 110 has a friction V-belt pulley; the belt will only rotate when the speed reaches a certain level.
