[0002] Coffee harvesting is a core part of the coffee cultivation industry, and its efficiency and quality directly affect the quality of coffee beans and the economic benefits of cultivation. The harvesting process is widely used in agricultural settings such as tropical plantations and mountain farms. Current coffee harvesting methods primarily rely on traditional manual picking and coffee harvesting equipment.

[0003] However, manual harvesting requires a large workforce for fruit sorting and harvesting, resulting in high labor costs and low harvesting efficiency. Furthermore, existing coffee harvesting equipment is complex to operate, heavy, difficult to carry, and labor-intensive, easily leading to damage and omission of coffee cherries. Therefore, a coffee harvesting device is proposed to address these problems. Utility Model Content

[0004] The purpose of this invention is to provide a vibrating coffee harvester that solves the technical problems of low coffee fruit harvesting efficiency and the fact that existing coffee harvesting equipment is complicated to operate, heavy and difficult to carry, and difficult, complicated and labor-intensive to operate, which easily leads to damage and omission of coffee fruits.

[0005] To achieve the above objectives, this utility model provides a vibrating coffee harvester, comprising:

[0006] handle;

[0007] A fixing tube is provided at one end of the handle, and the end of the fixing tube is connected to the assembly shell through an elastic member. A hook assembly is provided on the side of the assembly shell opposite to the handle.

[0008] A transmission rod is rotatably disposed on the circumferential inner side of the fixed tube, and an eccentric member is provided at the first end of the transmission rod, the eccentric member being located inside the assembly housing;

[0009] The transmission rod can be driven to rotate, thereby causing the eccentric component to rotate, which in turn causes the assembly shell and the claw assembly to vibrate.

[0010] Preferably, the claw assembly includes: a vibrating rod disposed on the side of the mounting housing away from the handle, the end of the vibrating rod being provided with a U-shaped claw and an L-shaped claw, the U-shaped claw having a first opening on the side facing the handle, and the L-shaped claw cooperating with the U-shaped claw to form a second opening away from the handle.

[0011] Preferably, the elastic member includes: a first assembly block disposed at the end of the fixed tube, the first assembly block being connected to a second assembly block via a vibration spring.

[0012] Preferably, the eccentric component includes: an eccentric wheel disposed at the first end of the transmission rod, the eccentric wheel being located inside the assembly housing, and the transmission rod being rotatably connected to the side of the assembly housing facing the handle.

[0013] Preferably, the mounting shell has a mounting hole on the side facing the handle, and a rolling bearing is installed in the mounting hole. The rolling bearing is sleeved on the outer peripheral side of the transmission rod.

[0020] (1) This utility model drives the transmission rod to rotate, thereby driving the eccentric component to rotate synchronously. While the eccentric component rotates, it drives the assembly shell to vibrate. The assembly shell drives the hook assembly to vibrate at a certain frequency. After the hook assembly is attached to the coffee tree branch, the vibration of the hook assembly is transmitted through the tree branch to the connection between the coffee fruit and the stem, so that the mature coffee fruit can quickly detach from the stem, effectively improving the coffee picking efficiency.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1 and Figure 2 As shown, to achieve the above objectives, this utility model provides a vibratory coffee harvester, including: a handle 1, a fixed tube 2 and a transmission rod 3 disposed on the handle 1. The fixed tube 2 is disposed at one end of the handle 1, specifically at the upper end of the handle 1. The upper end of the fixed tube 2 is connected to an assembly shell 7 via an elastic member 6. A hook assembly 4 is disposed on the left side of the assembly shell 7. The transmission rod 3 is rotatably disposed on the inner circumferential side of the fixed tube 2, meaning the rotating rod can rotate freely relative to the fixed tube 2. An eccentric member 5 is disposed at the upper end of the transmission rod 3. Driving the transmission rod 3 to rotate the eccentric member 5 synchronously causes it to rotate. The eccentric member 5 is located inside the assembly shell 7. Simultaneously, the rotation of the eccentric member 5 causes the assembly shell 7 to vibrate. The assembly shell 7 synchronously drives the hook assembly 4 to vibrate at a certain frequency. After the hook assembly 4 abuts against the coffee branch, the vibration of the hook assembly 4 is transmitted through the branch to the connection between the coffee fruit and the stem, causing the mature coffee fruit to quickly detach from the stem, effectively improving coffee harvesting efficiency.

[0030] In use, the drive transmission rod 3 is rotated to drive the eccentric component 5 to rotate synchronously. Simultaneously, the rotation of the eccentric component 5 causes the assembly shell 7 to vibrate. The assembly shell 7 then synchronously drives the hook assembly 4 to vibrate at a certain frequency. By holding the handle 1, the hook assembly 4 is controlled to abut against the coffee tree branch. The vibration of the hook assembly 4 is transmitted through the branch to the connection between the coffee fruit and the stem, until the coffee fruit detaches from the stem. By controlling the hook assembly to vibrate at a certain frequency, the optimal force for manual harvesting is precisely simulated. This allows for efficient harvesting of ripe fruit while avoiding damage to the coffee tree. It ensures harvesting efficiency while reducing damage and omissions of coffee fruit, preventing the harvesting of unripe coffee fruit along with the ripe fruit, and effectively improving raw material quality and subsequent processing efficiency.

[0031] like Figure 3 As shown, in one embodiment of this utility model, the claw assembly 4 includes: a vibrating rod 401 disposed on the side of the assembly housing 7 away from the handle 1, and a U-shaped claw 402 and an L-shaped claw 403 disposed at the end of the vibrating rod 401, as shown. Figure 3 As shown, a U-shaped hook 402 is provided at the upper end of the vibrating rod 401. The U-shaped hook 402 has a first opening 404 on the side facing the handle 1. When the branch is located at the first opening 404, the handle 1 is pulled and the U-shaped hook 402 can pull the branch, so that the U-shaped hook 402 presses against the branch to ensure that the vibration of the hook assembly 4 can be transmitted through the branch to the connection between the coffee fruit and the stem as much as possible, thereby improving the vibration effect on the connection between the coffee fruit and the stem.

[0032] In addition, an L-shaped hook 403 is provided at the upper end of the vibrating rod 401. The upper end of the L-shaped hook 403 is straight. The L-shaped hook 403 cooperates with the U-shaped hook 402 to form a second opening 405 facing away from the handle 1. When the branch is located at the second opening 405, the handle 1 is pushed, and the L-shaped hook 403 can hold the branch, so that the L-shaped hook 403 presses firmly against the branch. This ensures that the vibration of the hook assembly 4 can be transmitted through the branch to the connection between the coffee fruit and the stem as much as possible, improving the vibration effect on the connection between the coffee fruit and the stem. The setting of the U-shaped hook 402 and the L-shaped hook 403 allows the entire hook assembly to fit against the branch at multiple angles, achieving efficient harvesting of coffee fruits.

[0033] In one embodiment of this utility model, the elastic member 6 includes: a first assembly block 601 disposed at the end of the fixed tube 2, the first assembly block 601 being connected to a second assembly block 603 via a vibration spring 602, and both the first assembly block 601 and the second assembly block 603 having through holes on one side for the transmission rod 3 to pass through, so as to accommodate the assembly of the transmission rod 3. Specifically, the first assembly block 601 is fixedly connected to the upper end of the fixed tube 2, and the first assembly block 601 and the second assembly block 603 are connected via the vibration spring 602. The vibration spring 602 plays a certain role in vibration isolation. While the second assembly block 603 vibrates with the assembly hole, the vibration of the second assembly block 603 will not be transmitted to the first assembly block 601, so as to ensure that the worker can always hold the handle 1 stably, reduce the gripping force required when the worker holds the handle 1, and increase the comfort of the worker when holding the handle 1.

[0034] It should be noted that several vibration springs 602 can be set at equal angles on the outer circumference of the transmission rod 3, with the two ends of the vibration springs 602 connected to the first assembly block 601 and the second assembly block 603 respectively; alternatively, a vibration spring 602 with an inner diameter larger than the outer diameter of the transmission rod 3 can be directly fitted on the outer circumference of the transmission rod 3, with the two ends of the vibration spring 602 connected to the first assembly block 601 and the second assembly block 603 respectively. The specific number and arrangement of the vibration springs 602 are not limited; the purpose is to ensure that the fixed tube 2 is stably connected to the hook assembly while minimizing the transmission of vibration force from the hook assembly to the handle 1.

[0035] In one embodiment of this utility model, the eccentric component 5 includes an eccentric wheel 501 disposed at the first end of the transmission rod 3. Specifically, the eccentric wheel 501 is disposed at the upper end of the transmission rod 3 and is located inside the assembly housing 7. Under the drive of the transmission rod 3, the eccentric wheel 501 can rotate freely within the assembly housing 7. When the eccentric wheel 501 rotates, it will cause the upper end of the transmission rod 3 to swing to a certain extent. In addition, the side of the assembly housing 7 facing the handle 1 is rotatably connected to the transmission rod 3. When the transmission rod 3 swings, it will cause the assembly housing 7 to vibrate, forming a certain vibration effect.

[0036] Preferably, an assembly hole is provided on the side of the assembly shell 7 facing the handle 1, and a rolling bearing 701 is provided in the assembly hole. The rolling bearing 701 is sleeved on the outer peripheral side of the transmission rod 3. The rolling bearing 701 enables the transmission rod 3 to rotate stably relative to the assembly shell 7, reduces the friction between the transmission rod 3 and the assembly shell 7, and effectively improves the service life of the transmission rod 3 and the assembly shell 7.

[0037] Furthermore, a counterweight 502 is sleeved at the first end of the transmission rod 3, that is, the counterweight 502 is sleeved at the upper end of the transmission rod 3. The counterweight 502 is located on the lower side of the eccentric wheel 501 and is located inside the assembly shell 7. Preferably, the assembly block is cylindrical and the counterweight 502 is coaxially arranged with the transmission rod 3. The main function of the counterweight 502 is to increase the inertial force of the left end of the transmission rod 3 when it swings, thereby increasing the inertial force when the transmission rod 3 drives the assembly shell 7 to vibrate, so that the vibration force transmitted by the assembly shell 7 to the hook assembly is sufficient to make the mature coffee fruit quickly detach from the stem. It should be noted that by replacing the counterweights 502 with different masses and sizes and adjusting the position of the counterweights 502 on the axis of the transmission rod 3, the overall center of gravity distribution of the eccentric component 5 is optimized, and the unbalanced force when the transmission rod 3 is running is balanced. The counterweights 502 and the eccentric wheel 501 work together to make the hook assembly produce stable and appropriate vibration, which ensures that the ripe coffee cherries are shaken off while improving the stability of the hook assembly during vibration.

[0038] In one embodiment of this utility model, a driving mechanism is also provided, which includes a driving motor 8 disposed in the handle 1, an output end of the driving motor 8 being provided with a drive shaft 801, the axis of the drive shaft 801 being consistent with the length direction of the handle 1, and the drive shaft 801 being connected to the second end of the transmission rod 3 through a gear set 9. Specifically, the drive shaft 801 is connected to the lower end of the transmission rod 3 through the gear set 9, controlling the driving motor 8 to drive the drive shaft 801 to rotate in the forward direction, and the drive shaft 801 driving the transmission rod 3 to rotate through the gear set 9.

[0039] Preferably, the gear set 9 includes: a first spur gear sleeved on the drive shaft 801, the first spur gear meshing with a second spur gear, the second spur gear meshing with a third spur gear, and the third spur gear being coaxially arranged with the transmission rod 3. The radius and number of teeth of the first spur gear are smaller than those of the second spur gear, and the radius and number of teeth of the second spur gear are smaller than those of the third spur gear. By setting the transmission ratio between the first and second spur gears and between the second and third spur gears, the rotational speed of the transmission rod 3 is made smaller than the rotational speed of the drive shaft 801, increasing the torque of the transmission rod 3 and providing sufficient power support for the swing amplitude of the upper end of the subsequent transmission rod 3, that is, providing sufficient power support for the vibration of the hook assembly.

[0040] In one embodiment of this utility model, a power switch 10 and a controller 11 are provided inside the handle 1. The power switch 10 is connected to the controller 11 through a circuit. The controller 11 is connected to the power supply and the drive motor 8 through a circuit. The controller 11 is the core of the electronic control. When the power switch 10 is pressed, an electrical signal is transmitted to the controller 11 to trigger the start and stop of the drive motor 8. The controller 11 further controls the circuit between the power supply and the drive motor 8 to be connected or disconnected. The controller 11 can control the drive motor 8 to output power stably.

[0041] In addition, the controller 11 stably controls the speed of the drive motor 8, so that the rotating rod can drive the eccentric component 5 to rotate at a specific speed, thereby enabling the hook assembly 4 to reach a specific vibration frequency, thus accurately simulating the optimal force for manual picking, efficiently harvesting coffee fruits, avoiding damage to coffee trees, and greatly reducing the cost of manual picking.

[0042] It should be noted that, for medium-sized coffee beans, preferably, a 12V lithium battery is used for power supply, and the drive motor 8 is a low-power motor with a rated voltage of 12V and a power of 600W. The fixed vibration frequency of the vibrating rod 401 is set to 75Hz, ensuring efficient single-bean separation without manual adjustment. Compared with traditional multi-speed equipment, this reduces parameter adjustment steps and lowers the overall weight of the coffee harvester by reducing the adjustment mechanism, thus supporting longer continuous handheld operation. In addition, the controller 11 stably controls the speed of the drive motor 8 to replace the traditional adjustment mechanism, integrating parameters such as vibration frequency into the hardware design, achieving ready-to-use zero-adjustment operation, and significantly reducing operational complexity and equipment maintenance costs.

[0043] In one embodiment of this utility model, a support frame 12 is provided inside the handle 1. The support frame 12 has a cylindrical structure. By mounting the drive mechanism on the support frame 12, the drive mechanism is not directly mounted on the handle 1, making it easier to disassemble and assemble the drive mechanism and facilitating future maintenance or replacement of the drive mechanism.

[0044] Preferably, a buffer pad 13 is provided on the inner side wall of the handle 1. The buffer pad 13 can be made of rubber. The inner side wall of the buffer pad 13 is attached to the outer side wall of the support frame 12, and the outer side wall of the buffer pad 13 is attached to the inner side wall of the handle 1. The buffer pad 13 can reduce the vibration force transmitted to the handle 1 by the drive mechanism, and further increase the comfort of the worker when holding the handle 1.

[0045] When using this invention, pressing the power switch 10 sends an electrical signal to the controller 11, triggering the drive motor 8 to start. The drive motor 8 drives the drive shaft 801 to rotate, which in turn drives the transmission rod 3 to rotate via the gear set 9. The transmission rod 3 rotates, causing the eccentric wheel 501 and the counterweight 502 to rotate synchronously. Simultaneously, the rotation of the eccentric wheel 501 and the counterweight 502 causes the assembly shell 7 to vibrate. The assembly shell 7 then synchronously drives the hook assembly 4 to vibrate at a certain frequency. The handle 1 controls the hook assembly 4 to contact the coffee branch. The vibration of the hook assembly 4 is transmitted through the branch to the connection between the coffee fruit and the stem, until the coffee fruit detaches from the stem. When harvesting is no longer needed, pressing the power switch 10 again sends an electrical signal to the controller 11, triggering the drive motor 8 to stop operating.

[0046] In summary, by controlling the hook assembly to vibrate at a certain frequency, ripe coffee cherries are quickly detached from the stem, effectively improving coffee harvesting efficiency. This also reduces damage and loss of coffee cherries, preventing unripe cherries from being harvested along with them, thus improving raw material quality and subsequent processing efficiency. Furthermore, the single-handed operation of the handle 1 provides good convenience, meeting the needs of small-scale, precise harvesting, and enhancing its practicality.

[0047] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0048] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
