[0030] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as described in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] Please refer to the attached Figures 1 to 6 In one embodiment of the present invention, a binding type walnut picker includes a driving component 10, a vibration component 20 and a binding component 30 for binding a tree trunk; wherein the binding component 30 includes a connecting seat 310 and a clamping hoop component (not shown in the figure), the connecting seat 310 is connected to the vibration component 20, the clamping hoop component is connected to the connecting seat 310 and is used to bind the tree trunk, and the driving component 10 drives the vibration component 20 to vibrate to shake the walnuts off the walnut tree.

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

[0036] As a preferred embodiment, the driving 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 as a power source can provide stable and strong power output; the mechanical flexible shaft 120 can effectively transmit the power generated by the gasoline engine assembly 110 to the vibration assembly 20, so that the vibration assembly 20 can continuously and stably generate vibrations, thereby effectively shaking the walnuts off the walnut tree. The mechanical flexible shaft 120 is flexible and elastic, can adapt to the force transmission requirements of different angles and distances, and has good applicability.

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

[0039] The main frame assembly 40 of this embodiment adopts a frame-type 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 the present invention connects the gasoline engine assembly 110 and the vibration assembly 20 together through the mechanical flexible shaft 120. The gasoline engine assembly 110 and the vibration assembly 20 can be fixed on the main frame for use, or the gasoline engine assembly 110 and the vibration assembly 20 can be removed 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. The gasoline engine assembly 110 can also be started to achieve the picking operation.

[0041] As a preferred embodiment, the vibration assembly 20 includes a vibration head 210, a flip base 220 and a rotating shaft 230, wherein the vibration head 210 is connected to the bottom of the flip base 220, the flip base 220 is arranged at 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 method between the flip 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 picking effect.

[0043] It is worth noting that the vibration head 210 of the present application can adopt mature devices such as flexible shaft insertion vibrators and planetary insertion vibrators in the prior art. Figure 5-6As shown, the vibration head 210 includes an input end of the vibration 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 arranged 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 generate vibration; further, two third gears 215 are arranged, and two second gears 214 are arranged. The two second gears 214 are meshed, thereby realizing the synchronous movement of the two first gears 213. Each third gear 215 is provided with an eccentric block 216, and the position of the eccentric block is adaptively set to generate corresponding vibration, which will not be elaborated here.

[0044] As a preferred embodiment, the bottom of the vibration head 210 is provided with a first connecting plate 211, the first connecting plate 211 is provided with a first connecting hole 212 for bolts to pass through, and the flip base 220 is provided with second connecting holes 221 arranged at intervals along its own extension direction. The vibration head 210 is connected to the flip base 220 by bolts passing through the first connecting hole 212 and the second connecting hole 221.

[0045] The bolts penetrate the connection holes on the first connection plate 211 and the flip chassis 220 , thereby achieving a stable connection between the vibration head 210 and the flip chassis 220 .

[0046] like Figure 2 As shown, the first connecting plate 211 is provided with a first connecting hole 212, and the flip chassis 220 is provided with a plurality of second connecting holes 221 arranged at intervals along its own extension direction. This design allows the position of the vibration head 210 on the flip chassis 220 to be adjusted, and the height of the vibration head 210 can be adjusted according to the clampable height of the tree trunk. With the rotation of the flip chassis 220, the picking height and picking angle can be adjusted to improve adaptability. At the same time, the bolt connection method also makes the installation and disassembly process simpler and faster.

[0047] As a preferred embodiment, it also includes a tree-matching assembly 50 connected to the front end of the main frame assembly 40, and the tree-matching 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, 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 rope holes 530 for ropes to pass through are respectively provided at both ends of the arc-shaped docking plate 520.

[0048] Specifically, the arc-shaped docking plate 520 of the tree assembly 50 is designed to fit the shape of the tree trunk. This design not only increases the contact area between the picker and the tree trunk, improves the stability during the picking process, but also can more effectively transmit vibration energy. The arc-shaped docking plate 520 is connected to the front end of the main frame assembly 40 through the second connecting plate 510 to form a stable support structure. The arc-shaped docking plate 520 is aligned with the tree trunk, and the structure of the present application is tied to the tree trunk through the rope threading hole 530 with a rope to prevent the main frame assembly 40 from slipping.

[0049] As a preferred embodiment, the clamp assembly includes two clamp units 320 arranged at intervals along the length direction of the vibration head 210, and the 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, and the first arc plate 321 is provided with a first through hole for the screw 323 to pass through, and the second arc plate 322 is provided with a second through hole arranged one-to-one with the first through hole. The screw 323 is screwed with a first nut 324 on the outer side of the first arc plate 321, and the screw 323 is screwed with a second nut 325 on the outer side of the second arc plate 322.

[0050] Specifically, the hoop assembly is composed of two hoop units 320 arranged at intervals along the length direction of the vibration head 210, and each hoop unit 320 is arranged relatively by a first arc plate 321 and a second arc plate 322 and fixed by a screw 323, a first nut 324 and a second nut 325. The hoop assembly can be tightly fixed on the trunk, preventing the picking machine from shaking and falling off during the vibration process, and improving the stability and safety of picking. Since the hoop unit 320 is composed of two arc plates, they can adapt to 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 hoop unit 320 can be easily adjusted to make it fit closely to trunks of different sizes, thereby enhancing the adaptability and flexibility of the picking machine. The installation and removal process of the hoop assembly is relatively simple. It is only necessary to place the first arc plate 321 and the second arc plate 322 around the 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 necessary. The arc plate, screw 323 and nut design of the clamp assembly can reduce the pressure point on the tree trunk to a certain extent, avoiding direct damage to the tree trunk. This design helps to protect the health of the tree trunk and reduce potential damage to the tree caused by picking operations.

[0051] Furthermore, a universal wheel 410 is provided at the bottom of the main frame assembly 40. The design of the universal wheel 410 enables the entire harvester to move easily on the ground, greatly improving the use range of the harvester and enabling it to adapt to various complex working environments.

[0052] Furthermore, the main frame assembly 40 is connected to a push frame 60 at one end away from the tree assembly 50. The design of the push frame 60 enables the operator to easily push or pull the picker to move and position it. This design greatly reduces the physical burden of the operator and improves the efficiency of the picking operation.

[0053] Furthermore, it also includes a first bearing seat 420 and a second bearing seat 430 which are relatively arranged on both sides of the main frame assembly 40, and the rotating shaft 230 is 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 are relatively arranged on both sides of the main frame assembly 40, providing stable support for the rotating shaft 230. This design ensures that the rotating shaft 230 can remain stable during the rotation process, reducing the shaking and deviation caused by vibration or external force.

[0054] Workflow: pull or push the walnut picker to the front of the tree trunk, align the tree assembly 50 with the tree trunk, and use a rope to pass through the rope hole 530 to tie the walnut picker and the tree trunk to prevent the walnut picker from slipping. Then, lift the vibration head 210 by flipping the chassis 220, align the vibration head 210 with the tree trunk or branch, and tie the vibration head 210 to the tree trunk through the clamp unit 320. Then start the gasoline engine assembly 110 to increase the speed of the gasoline engine assembly 110 to complete the vibration operation. Preferably, there is a friction V-belt pulley on the gasoline engine assembly 110, and the belt will only be driven to rotate when the speed reaches a certain level.
