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.

[0045] Please refer to the attached Figures 1 to 7 In one embodiment of the present invention, a fruit harvester includes a machine body 10, a hoisting mechanism 20, a vibration mechanism 30 and a rope (not shown), wherein the hoisting mechanism 20 and the vibration mechanism 30 are both connected to the machine body 10, wherein:

[0046] The rope includes a first section (not shown in the figure), a second section (not shown in the figure) and a third section (not shown in the figure) arranged in sequence along its extension direction, the first section is used to connect to a fruit tree (for example, to a branch of a walnut tree), the second section is wound around the vibration mechanism 30, and the third section is connected to the hoisting mechanism 20;

[0047] The hoisting mechanism 20 has a rotating state and a locking state. When the hoisting mechanism 20 is in the rotating state, the hoisting mechanism 20 drives the third section to be wound around the hoisting mechanism 20 to gradually tighten the rope; when the hoisting mechanism 20 is in the locking state, the vibration mechanism 30 drives the rope to generate a pulling force to shake the fruits off.

[0048] Specifically, the winch mechanism 20 is used to control the length of the rope. For fruit trees at different heights and distances, the rope can be wound around the winch mechanism 20 by starting the winch mechanism 20 in a rotating state, thereby changing the suspended length of the rope. The vibration mechanism 30 generates vibration to drive the rope to generate a pulling force to shake the fruits off the forest. The rope is divided into three sections. The first section is connected to the fruit tree, the second section is wound around the vibration mechanism 30, and the third section is connected to the winch mechanism 20.

[0049] Working process: The first section of rope is connected to the fruit tree to be harvested. When the hoisting mechanism 20 is in a rotating state, it will drive the third section of rope to be wound around the hoisting mechanism 20, thereby gradually tightening the rope. When the rope is pulled to a certain extent, the hoisting mechanism 20 switches to a locked state. At this time, the vibration mechanism 30 starts to work, and by vibrating the second section of rope, this vibration will be transmitted to the first section of rope, and then to the fruit tree, pulling the fruit tree (such as walnut tree) or branches, thereby shaking off the mature fruits.

[0050] The present application can improve the harvesting efficiency. Traditional forest fruit harvesting requires a lot of manpower to climb and shake branches, while the present application can greatly reduce the labor intensity of people and save manpower. Since the rope can be connected to different fruit trees, the present application can adapt to fruit trees of different types and sizes and has strong versatility. Using the present application for harvesting can avoid the safety risks brought by people directly climbing fruit trees and improve the safety of harvesting operations.

[0051] As a preferred embodiment, the vibration mechanism 30 includes a first frame 310, a first driving mechanism 320, a transmission assembly 330 and an eccentric vibration assembly 340, wherein:

[0052] The first driving mechanism 320 is installed on the first frame 310, the transmission assembly 330 is connected to the driving end of the first driving mechanism 320, the transmission assembly 330 is connected to the eccentric vibration assembly 340, the eccentric vibration assembly 340 is rotatably connected to the first frame 310, the second section is wound around the eccentric vibration assembly 340, the first driving mechanism 320 drives the transmission assembly 330 to move and drive the eccentric vibration assembly 340 to rotate, so as to drive the rope to generate a pulling force to shake the fruits off.

[0053] Specifically, the first frame 310 is a supporting structure to ensure that other components can work stably. The first driving mechanism 320 preferably uses a motor whose speed is adjustable, so that the vibration frequency can be adjusted. When the speed of the motor increases, the vibration frequency of the eccentric vibration component 340 will also increase accordingly; the eccentric vibration component 340 is a key component for generating vibration. When rotating, it will generate unbalanced centrifugal force, thereby generating vibration.

[0054] Working process: when the vibration mechanism 30 needs to work, first start the first driving mechanism 320, the first driving mechanism 320 transmits the driving force to the eccentric vibration component 340 through the transmission component 330, the eccentric vibration component 340 starts to rotate under the action of the driving force, generates an unbalanced centrifugal force, drives the rope connected to it to generate tension and relaxation, and the mature fruits will be separated from the branches due to inertia, thereby achieving the purpose of shaking off the fruits.

[0055] As a preferred embodiment, the eccentric vibration assembly 340 includes a first rotating disk 350, a second rotating disk 360, a third rotating disk 370, a connecting member (not shown) and an eccentric sleeve 380; wherein,

[0056] The first rotating disk 350, the second rotating disk 360, and the third rotating disk 370 are all rotatably connected to the first frame 310, and the first rotating disk 350, the second rotating disk 360, and the third rotating disk 370 are arranged coaxially;

[0057] The second rotating disk 360 is connected to the first rotating disk 350 through the connecting member and rotates synchronously with the first rotating disk 350. The third rotating disk 370 moves synchronously with the second rotating disk 360. An eccentric block 390 is provided on the end surface of the third rotating disk 370.

[0058] The eccentric sleeve 380 and the first rotating disk 350 are eccentrically arranged. The eccentric sleeve 380 is rotatably sleeved on the outer peripheral wall of the connecting member, and the second section is wound on the outer peripheral wall of the eccentric sleeve 380 .

[0059] Specifically, the first rotating disk 350 is a starting rotating component of the eccentric vibration assembly 340, rotatably connected to the first frame 310, and receives the driving force from the transmission assembly 330. The second rotating disk 360 is connected to the first rotating disk 350 through a connecting member, and the two can rotate synchronously. The third rotating disk 370 moves synchronously with the second rotating disk 360. An eccentric block 390 is provided on the end surface of the third rotating disk 370 to generate unbalanced centrifugal force. The eccentric shaft sleeve 380 is eccentrically arranged with the first rotating disk 350 and rotatably sleeved on the outer peripheral wall of the connecting member.

[0060] The transmission assembly 330 transmits the driving force of the first driving mechanism 320 to the first rotating disk 350. The first rotating disk 350 drives the second rotating disk 360 to rotate synchronously through the connecting member, and then drives the third rotating disk 370 to move synchronously. The eccentric block 390 on the third rotating disk 370 generates an unbalanced centrifugal force as the third rotating disk 370 rotates. At the same time, since the eccentric sleeve 380 is eccentrically arranged with the first rotating disk 350, the eccentric sleeve 380 is similar to the tension wheel of the rope. When the first rotating disk 350 rotates, the eccentric sleeve 380 will generate forces of different degrees of tightness on the rope, thereby driving the rope to generate tension and relaxation forces. The mature fruits will be separated from the branches due to inertia, thereby achieving the purpose of shaking off the fruits.

[0061] As a preferred embodiment, the transmission assembly 330 includes a first bevel gear 331 and two second bevel gears 332 relatively arranged on both sides of the first bevel gear 331, the number of the eccentric vibration assemblies 340 is two, and the eccentric vibration assemblies 340 and the second bevel gears 332 are arranged in a one-to-one correspondence;

[0062] The first bevel gear 331 is connected to the driving end of the first driving mechanism 320, each of the second bevel gears 332 is meshed with the first bevel gear 331, the two second bevel gears 332 rotate in opposite directions, and each of the second bevel gears 332 drives the first rotating disk 350 of the corresponding eccentric vibration assembly 340 to rotate.

[0063] Specifically, since two second bevel gears 332 are relatively arranged on both sides of the first bevel gear 331 in the transmission assembly 330, and the two second bevel gears 332 are meshed with the first bevel gear 331 and rotate in opposite directions, the two eccentric vibration assemblies 340 can be driven to work in opposite directions of rotation. Furthermore, the two second bevel gears 332 have the same number of teeth, which can make the vibration mechanism 30 produce opposite movements of equal frequency and amplitude, thereby improving the harvesting efficiency. The transmission assembly 330 adopts a bevel gear transmission method, so that the entire transmission system has a compact structure and a small size. This helps to reduce the volume and weight of the entire fruit harvester.

[0064] Furthermore, the eccentric sleeve 380 includes a sleeve (not shown) and a bearing (not shown), the bearing is mounted on the outer peripheral wall of the connecting member, and the sleeve is connected to the outer peripheral wall of the bearing so that the sleeve can be rotatably arranged.

[0065] In this embodiment, the bearing is mounted on the outer peripheral wall of the connecting member (for example, by means of interference fit or transition fit), and the bushing is connected to the outer peripheral wall of the bearing, so as to accommodate the rotation of the first rotating disk 350 .

[0066] As a preferred embodiment, the hoisting mechanism 20 includes a second frame 210, a second driving mechanism 220, a hoisting drum assembly 230 and a brake assembly 234; wherein,

[0067] The second driving mechanism 220 is connected to the second frame 210;

[0068] The hoisting drum assembly 230 is rotatably connected to the second frame 210, and the brake assembly 234 has a braking state and a separation state. When in the braking state, the hoisting drum assembly 230 is in the locking state, and when in the separation state, the second driving mechanism 220 drives the hoisting drum assembly 230 to be in the rotating state.

[0069] Specifically, the second frame 210 is used as a supporting structure to ensure that other components can work stably. The second driving mechanism 220 preferably adopts a reduction motor. The hoisting drum assembly 230 is used to wind and release the rope, and is rotatably connected to the second frame 210, and the rope is retracted and released by rotation. The brake assembly 234 is used to lock the rotation of the hoisting drum assembly 230, and has two working modes: a brake state and a separation state. When the hoisting mechanism 20 needs to work, the second driving mechanism 220 is started. When the brake assembly 234 is in a separation state, the brake mechanism will not generate resistance to the hoisting drum assembly 230. At this time, the second driving mechanism 220 can drive the hoisting drum assembly 230 to rotate freely. With the operation of the second driving mechanism 220, the hoisting drum assembly 230 starts to rotate, and the rope can be wound or released according to actual needs. When the rotation of the hoisting drum assembly 230 needs to be stopped, the brake assembly 234 switches to a brake state, and the rotation of the hoisting drum assembly 230 is locked by friction or mechanical locking, etc., to ensure that the rope will not continue to move due to inertia. The design of the brake assembly 234 enables the winch drum assembly 230 to be locked quickly and accurately when it needs to stop, avoiding the loosening or accidental release of the rope due to inertia, and improving the stability and safety of the work.

[0070] As a preferred embodiment, the winch drum assembly 230 includes a cylinder body 231, a rotating shaft 232 and a brake friction disc 233; wherein the rotating shaft 232 is rotatably connected to the second frame 210, the cylinder body 231 and the rotating shaft 232 are connected and move synchronously with the rotating shaft 232; the brake friction disc 233 is connected to the outer peripheral wall of the rotating shaft 232 and moves synchronously with the rotating shaft 232, the brake friction disc 233 is arranged on the outer side of the second frame 210, and the brake friction disc 233 matches the brake assembly 234; wherein, when the brake assembly 234 brakes the brake friction disc 233, the cylinder body 231 is in the locked state.

[0071] Specifically, the cylinder 231 is used to wind and release the rope, and is the main part of the winch cylinder assembly 230. The rotating shaft 232 is connected to the cylinder 231 and enables it to rotate, for example, it is rotatably connected to the second frame 210 through a bearing; the brake friction disc 233 is connected to the outer peripheral wall of the rotating shaft 232, moves synchronously with the rotating shaft 232, and is used to cooperate with the brake assembly 234 to realize the locking function.

[0072] As a preferred embodiment, the brake assembly 234 includes a mounting frame 2341, a brake gear 2342, an upper brake pad 2343 and a lower brake pad 2345;

[0073] The end surface of the upper brake pad 2343 away from the second frame 210 is provided with a first convex column 2344, and the end surface of the lower brake pad 2345 away from the second frame 210 is provided with a second convex column 2346;

[0074] The mounting frame 2341 is fixedly connected to the second frame 210, and the mounting frame 2341 is provided with a first through hole 23411 matching the first convex column 2344, a second through hole 23412 matching the second convex column 2346, and a third through hole 23413 for the rotation shaft 232 to pass through, the first through hole 23411 and the second through hole 23412 are oppositely arranged on both sides of the third through hole 23413, and the mounting frame 2341 is formed with a limiting groove 23414 for the upper brake pad 2343 and the lower brake pad 2345 to move vertically, and the upper brake pad 2343 and the lower brake pad 2345 are movably arranged along the limiting groove 23414;

[0075] The brake gear 2342 is rotatably arranged relative to the mounting frame 2341, and the brake gear 2342 is provided with a through hole 23421 for the rotation shaft 232 to pass through, the brake gear 2342 is provided with a first arc-shaped hole 23422 matching the first convex column 2344, and a second arc-shaped hole 23423 matching the second convex column 2346, and the aperture of the second through hole 23412 is larger than the outer diameter of the rotation shaft 232;

[0076] When the brake gear 2342 rotates in a first direction, it drives the upper brake pad 2343 and the lower brake pad 2345 to move in a direction close to the brake friction disc 233 until the brake friction disc 233 is braked, so that the cylinder 231 is in the locked state; when the brake gear 2342 rotates in a second direction, it drives the upper brake pad 2343 and the lower brake pad 2345 to move in a direction away from the brake friction disc 233; the first direction and the second direction are opposite.

[0077] Specifically, when the brake friction disc 233 needs to be braked, the brake gear 2342 will rotate in the first direction. Due to the design of the first arc hole 23422 and the second arc hole 23423, the rotation of the brake gear 2342 will drive the upper brake pad 2343 and the lower brake pad 2345 to move along the limiting groove 23414 toward the direction close to the brake friction disc 233. As the brake gear 2342 continues to rotate, the upper brake pad 2343 and the lower brake pad 2345 will gradually contact the brake friction disc 233 and generate friction until the brake friction disc 233 is braked, so that the cylinder 231 is in a locked state.

[0078] When the brake needs to be released, the brake gear 2342 rotates in a second direction opposite to the first direction. Similarly, due to the design of the first arc hole 23422 and the second arc hole 23423, the rotation of the brake gear 2342 drives the upper brake pad 2343 and the lower brake pad 2345 to move along the limiting groove 23414 in a direction away from the brake friction disc 233, thereby releasing the brake.

[0079] By integrating the brake gear 2342, the upper brake pad 2343 and the lower brake pad 2345 on a mounting frame 2341, a compact structure is achieved, which is beneficial to saving space and reducing costs; the brake can be tightened and released by rotating the brake gear 2342, without the need for a complex mechanical structure or additional power source, and is easy to operate and maintain.

[0080] Preferably, the inner wall of the upper brake pad 2343 and the inner wall of the lower brake pad 2345 are in an arc shape matching the brake friction disc 233 .

[0081] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
