[0053] Specifically, the first rack 310 is a support structure to ensure that other components can work stably, the first driving mechanism 320 preferably adopts a motor, the rotating speed of the motor can be adjusted, so that the vibration frequency can be adjusted, and when the rotating speed of the motor increases, the vibration frequency of the eccentric vibration assembly 340 will also increase accordingly; the eccentric vibration assembly 340 is a key component for generating vibration, and when it rotates, it will generate unbalanced centrifugal force, thereby generating vibration.

[0054] Work flow: 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 assembly 340 through the transmission assembly 330, the eccentric vibration assembly 340 starts to rotate under the action of the driving force, generates unbalanced centrifugal force, drives the rope connected thereto to generate a tension and relaxation force, and the mature fruit will be separated from the branches due to inertia, thereby achieving the purpose of shaking off the fruit.

[0055] As a preferred embodiment, the eccentric vibration assembly 340 comprises a first rotating disc 350, a second rotating disc 360, a third rotating disc 370, a connecting piece (not marked in the figure) and an eccentric shaft sleeve 380; wherein,

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

[0057] The second rotating disc 360 is connected with the first rotating disc 350 through the connecting member and rotates synchronously with the first rotating disc 350, the third rotating disc 370 moves synchronously with the second rotating disc 360, and an eccentric block 390 is arranged on the end face of the third rotating disc 370;

[0058] The eccentric shaft sleeve 380 is arranged eccentrically with the first rotating disc 350, 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 shaft sleeve 380.

The eccentric shaft sleeve 380 is arranged eccentrically with the first rotating disc 350 and is 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 disc 350, the first rotating disc 350 drives the second rotating disc 360 to rotate synchronously through the connecting member, and in turn drives the third rotating disc 370 to move synchronously, and the eccentric block 390 on the third rotating disc 370 generates an unbalanced centrifugal force with the rotation of the third rotating disc 370. At the same time, since the eccentric shaft sleeve 380 is arranged eccentrically with the first rotating disc 350, the eccentric shaft sleeve 380 is similar to a tension pulley of a rope, and when the first rotating disc 350 rotates, the eccentric shaft sleeve 380 will generate a force with different tightness degrees on the rope, so as to drive the rope to generate a tight and loose tension force, and mature fruits will be separated from the branches due to inertia, so as to achieve the purpose of shaking off the fruits.

[0061] As a preferred embodiment, the transmission assembly 330 comprises a first bevel gear 331 and two second bevel gears 332 arranged oppositely 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 one by one in correspondence.

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

[0063] Specifically, since the transmission assembly 330 is provided with two second bevel gears 332 oppositely arranged on both sides of the first bevel gear 331, and the two second bevel gears 332 are engaged with the first bevel gear 331 and rotate in opposite directions, the two eccentric vibration assemblies 340 can be driven to work in opposite rotating directions, respectively. Further, the two second bevel gears 332 have the same number of teeth, so that the vibration mechanism 30 can produce opposite motions with equal frequency and equal amplitude, thereby improving the harvesting efficiency. The transmission assembly 330 adopts the bevel gear transmission mode, so that the whole transmission system has compact structure and small volume. This helps to reduce the volume and weight of the whole fruit harvesting machine.

[0064] Further, the eccentric shaft sleeve 380 comprises a shaft sleeve (not shown) and a bearing (not shown) mounted on the outer peripheral wall of the connecting piece, and the shaft sleeve is connected to the outer peripheral wall of the bearing, so that the shaft sleeve is rotatably arranged.

[0069] Specifically, the second rack 210 serves as a support structure to ensure stable operation of other components, and the second driving mechanism 220 preferably adopts a speed-reducing motor. The winding drum assembly 230 is used to wind and release the rope and is rotatably connected to the second rack 210 to realize winding and releasing of the rope through rotation. The brake assembly 234 is used to lock the rotation of the winding drum assembly 230 and has two working modes, i.e., a braking state and a separation state. When the winding mechanism 20 needs to work, the second driving mechanism 220 is started, and when the brake assembly 234 is in the separation state, the brake mechanism does not generate resistance to the winding drum assembly 230, so that the second driving mechanism 220 can drive the winding drum assembly 230 to rotate freely. With the operation of the second driving mechanism 220, the winding drum assembly 230 starts to rotate, and according to actual needs, the rope can be wound or released. When the rotation of the winding drum assembly 230 needs to be stopped, the brake assembly 234 is switched to the braking state to lock the rotation of the winding drum assembly 230 through friction or mechanical locking, so as to ensure that the rope does not continue to move due to inertia. The design of the brake assembly 234 enables the winding drum assembly 230 to be quickly and accurately locked when it needs to be stopped, avoiding loosening or accidental release of the rope due to inertia, and improving the stability and safety of work.

[0070] As a preferred embodiment, the winding drum assembly 230 comprises a drum body 231, a rotating shaft 232, and a brake friction disc 233.

The brake friction disc 233 is arranged outside the second rack 210 and is matched with the brake assembly 234. When the brake assembly 234 brakes the brake friction disc 233, the drum body 231 is in the locked state.

[0071] Specifically, the drum body 231 is used to wind and release the rope and is the main part of the winding drum assembly 230. The rotating shaft 232 is connected to the drum body 231 and enables it to rotate, for example, by being rotatably connected to the second rack 210 through a bearing. 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 to realize the locking function in cooperation with the brake assembly 234.

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

[0073] The end face of the upper brake pad 2343 away from the second rack 210 is provided with a first protruding column 2344, and the end face of the lower brake pad 2345 away from the second rack 210 is provided with a second protruding column 2346.

[0074] The mounting frame 2341 is fixedly connected with the second rack 210, and is provided with a first through hole 23411 matched with the first protruding column 2344, a second through hole 23412 matched with the second protruding column 2346, and a third through hole 23413 through which the rotating shaft 232 penetrates, the first through hole 23411 and the second through hole 23412 are oppositely arranged on the two sides of the third through hole 23413, the mounting frame 2341 is formed with a limiting groove 23414 for vertical movement of the upper brake pad 2343 and the lower brake pad 2345, 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 is provided with a through hole 23421 through which the rotating shaft 232 penetrates, a first arc-shaped hole 23422 matched with the first protruding column 2344, and a second arc-shaped hole 23423 matched with the second protruding column 2346, and the hole diameter of the second through hole 23412 is greater than the outer diameter of the rotating shaft 232.

[0076] When the brake gear 2342 rotates in a first direction, the upper brake pad 2343 and the lower brake pad 2345 are driven to move towards the brake friction disc 233 until the brake friction disc 233 is tightened, so that the cylinder 231 is in the locked state; when the brake gear 2342 rotates in a second direction, the upper brake pad 2343 and the lower brake pad 2345 are driven to move 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 tightened, the brake gear 2342 rotates in a first direction, and due to the design of the first arc-shaped hole 23422 and the second arc-shaped 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 towards the brake friction disc 233. With the continuous rotation of the brake gear 2342, the upper brake pad 2343 and the lower brake pad 2345 gradually contact and generate friction with the brake friction disc 233, until the brake friction disc 233 is tightened, so that the cylinder 231 is in the 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-shaped hole 23422 and the second arc-shaped 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 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 the mounting frame 2341, the structure is compact, which is beneficial to save space and reduce cost; by rotating the brake gear 2342, the brake can be tightened and released, without the need for complex mechanical structure or additional power source, which is simple and 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 arc-shaped and matched with the brake friction disc 233.
