Description

Technical Field

[0001] This application relates to the field of coffee harvesting technology, and more particularly to a coffee manual harvesting device. Background Technology

[0002] Coffee is typically grown in mountainous areas, some of which are steep enough to prevent the use of large machinery for harvesting. Furthermore, because the cherries don't all ripen at once, large machinery would mix in many unripe cherries, resulting in inconsistent quality. Therefore, high-quality coffee requires manual harvesting, which demands a significant workforce. The flavor of coffee also varies depending on when it's harvested. Generally, it can be categorized as semi-ripe (yellow-red), ripe (fully red), and overripe (purple-black). If harvested too early, semi-ripe coffee beans will taste more acidic; if harvested too late, the beans will be overripe and taste more bitter.

[0003] Chinese patent application No. CN 209897656 U, entitled "A Coffee Cherry Picker," discloses a coffee picking tool. Based on the different connection forces between immature and mature cherries and their stems, it uses vibration to separate mature cherries from their stems, enabling selective picking of mature coffee cherries. However, it can only pick coffee cherries with a high degree of ripeness, which are usually overripe and have a slightly lower taste compared to fully ripe coffee. Therefore, this tool is not suitable for picking fully ripe coffee. Utility Model Content

[0004] This application provides a coffee harvesting device to at least solve the problems of coffee harvesting technology in the prior art.

[0005] According to this application, a coffee manual picking device is provided, including a drive shaft and picking modules. The picking modules are provided in multiple ways and have hinge holes at both ends, which can be hinged to adjacent picking modules through the hinge shaft. At least two of the outermost picking modules are provided with drive shafts. By moving or rotating the drive shafts, the multiple picking modules that are hinged together can be moved or rotated to close into a closed ring or open into a straight line or arc. The picking modules are provided with multiple elastic picking fingers that extend inward. The elastic picking fingers have a certain elasticity or are connected to elastic components, so that the elastic picking fingers can bend or bend under the action of an external force in the axial direction of a certain hinge shaft.

[0006] Compared with existing technologies, the coffee manual harvesting device of this application has the following advantages:

[0007] First, use the drive shaft to open the articulated picking module into a straight line or arc and place it under the branch with coffee berries. Then, use the drive shaft to rotate the articulated picking module into a ring shape, wrapping the branch with coffee berries inside the articulated picking module. Move the articulated picking module along the axis of rotation, which is the direction in which the coffee branch extends. The elastic picking finger touches the coffee berries and uses friction or elasticity to scrape the ripe berries off the branch. Repeat the above steps as needed. The elasticity of the elastic picking finger can be adjusted, or different elastic picking fingers may have different elasticity values. Choose the appropriate one according to your picking needs.

[0008] In one embodiment, the hinge shaft is provided with multiple picking modules along its axial direction, and the multiple picking modules use the same hinge shaft. This design can complete the picking more fully. Since different coffee beans grow in different positions, the multiple picking modules can be staggered with each other by a certain position.

[0009] In one embodiment, the picking module is provided with a spring hole, the central axis of the spring hole is at a certain angle to the hinge axis, and a control spring is provided in the spring hole. The upper end of the control spring is connected to the elastic picking finger, and the lower end is fixed to the adjusting cylinder. The adjusting cylinder is provided with an adjusting screw so that the length of the control spring can be changed by adjusting the screw. The longer the spring is, the greater the contraction elasticity, which can pick coffee of different ripeness.

[0010] In one embodiment, the picking module has two spring holes, and a sleeve extending a certain length is provided at the upper end of the spring holes. The elastic picking fingers are installed above the sleeve. This design can increase the number and density of elastic picking fingers.

[0011] In one embodiment, the coffee manual harvesting device also includes a waist belt and a support frame. The waist belt is equipped with multiple magnets, the ends of which are spherical. The rear end of the support frame is made of ferromagnetic material and has a telescopic rod. The harvesting module is directly or indirectly fixed to the telescopic rod. This design reduces the strain on the arms and utilizes waist support to reduce labor intensity.

[0012] In one embodiment, a collecting net is provided below the telescopic pole, and the collecting net has multiple parts to collect coffee at different ripeness levels, making it more convenient to collect coffee at different ripeness levels.

[0013] In one embodiment, the telescopic rod includes a left rod and a right rod, with a front crossbar and a rear crossbar at both ends of the left rod and the right rod. A first sliding rod and a second sliding rod are provided between the front and rear crossbars. A first collecting net is provided between the left rod and the first sliding rod, a second collecting net is provided between the first and second sliding rods, and a third collecting net is provided between the second sliding rod and the right rod, thus facilitating the switching between different collecting nets.

[0014] In one embodiment, the coffee manual harvesting device also includes a spray tank and a spray pipe. The spray tank is equipped with a water pump so that the spray pipe can spray water onto the coffee branches, thus wetting the stems and making it easier to collect overripe coffee.

[0015] In one embodiment, the coffee harvesting device also includes an air pump and an air pipe. The air pipe, under the action of the air pump, can spray a high-speed airflow onto the coffee branches, which facilitates the collection of overripe coffee.

[0016] In one embodiment, the coffee harvesting device also includes a vibrating rod with a hook at the front so that the hook can be hung on a branch, thus facilitating the collection of overripe coffee.

[0031] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Example 1:

[0033] like Figure 1 and Figure 4 As shown, a coffee manual harvesting device includes a drive shaft 1 and harvesting modules 2. Each harvesting module 2 has multiple modules, each with hinge holes 20 at both ends, allowing them to be hinged to adjacent modules via hinge shafts 3 to form a chain structure. At least two of the outermost harvesting modules 2 are equipped with drive shafts 1. The drive shafts 1 can be relatively long for easy control. By moving or rotating the drive shafts 1, the multiple hinged harvesting modules 2 can be moved or rotated to close into a closed loop or open into a straight line or arc. Each harvesting module 2 has multiple inwardly extending, protruding elastic harvesting fingers 21. These elastic fingers 21 have a certain elasticity or are connected to elastic components, allowing them to bend or fold under the action of an external force along the axial direction of the hinge shaft 3. The drive shaft 1 can be equipped with a handle for convenient two-handed control of its movement or rotation.

[0034] like Figure 2 As shown, at this time, multiple harvesting modules 2 are in the closed position, with the coffee branch 9 at the center. Harvesting can be achieved by axial movement. Figure 3 As shown, at this time, multiple picking modules 2 are in the open state, and can be moved to the target coffee branch 9 and then closed to continue picking.

[0035] In one embodiment, the hinge shaft 3 is axially provided with multiple picking modules 2, and the multiple picking modules 2 use the same hinge shaft 3. Different picking modules 2 can be staggered by a certain position or the hinge shaft 3 can be tilted. The staggered position can be achieved by changing the position of the hinge hole 20.

[0036] Example 2:

[0037] like Figure 5 and Figure 6 As shown, in one embodiment, the picking module 2 is provided with a spring hole 22, the central axis of which forms a 45° angle with the hinge axis 3. A control spring 23 is provided inside the spring hole 22. The upper end of the control spring 23 is connected to the elastic picking finger 21, and the lower end is fixed to the adjusting cylinder 24. The adjusting cylinder 24 is partially inserted into the spring hole 22, and the adjusting cylinder 24 is provided with an adjusting screw 25 so that the length of the control spring 23 can be changed by adjusting the screw 25. When the elastic picking finger 21 is subjected to external force, it can stretch the control spring 23.

[0038] In one embodiment, the picking module 2 is provided with different numbers of spring holes 22 as needed. The figure shows two spring holes 22. The upper end of the spring hole 22 is provided with a sleeve 26 extending a certain length, and the elastic picking finger 21 is installed above the sleeve 26.

[0039] Example 3:

[0040] like Figure 7 , Figure 8 and Figure 9 As shown, in one embodiment, the coffee manual harvesting device also includes a belt 5 and a support frame 7. The belt 5 is equipped with multiple magnets 6 at different heights. The ends of the magnets 6 are spherical to facilitate the rotation of the contact parts. The rear end of the support frame 7 is made of ferromagnetic material and can be attracted by the magnets 6. The support frame 7 is equipped with a telescopic rod 8, and the harvesting module 2 is fixed to the telescopic rod 8 by an arched frame 4. In the figure, up, down, left, right, front, and back are relative positions, which can be changed according to specific circumstances in actual use.

[0041] In one embodiment, a collection net 10 is provided below the telescopic rod 8, and the collection net 10 is provided with multiple collection nets for collecting coffee at different ripeness levels.

[0042] In one embodiment, the telescopic rod 8 includes a left rod 81 and a right rod. A front crossbar 83 and a rear crossbar 84 are provided at both ends of the left rod 81 and the right rod 82. A first sliding rod 85 and a second sliding rod 86 are provided between the front crossbar 83 and the rear crossbar 84. The first sliding rod 85 and the second sliding rod 86 can slide on the front crossbar 83 and the rear crossbar 84. A first collecting net 101 is provided between the left rod 81 and the first sliding rod 85. A second collecting net 102 is provided between the first sliding rod 85 and the second sliding rod 86. A third collecting net 103 is provided between the second sliding rod 86 and the right rod 82. The arched frame 4 has two mounting holes for fitting or fixing onto the left rod 81 and the right rod 82.

[0043] In one embodiment, the coffee hand-picking device also includes a spray tank 11 and a spray pipe 12, wherein the spray tank 11 is equipped with a water pump so that the spray pipe 12 can spray water onto the coffee branches 9.

[0044] In one embodiment, the coffee hand-picking device further includes an air pump and an air pipe 13, which, under the action of the air pump, can spray a high-speed airflow onto the coffee branches 9. The air pipe 13 can be fixed together with the spray pipe 12.

[0045] In one embodiment, the coffee hand-picking device also includes a vibrating rod 14, with a hook 15 in front of the vibrating rod 14 so that the hook 15 can be hung on the branch.

[0046] This device can harvest coffee cherries at different ripeness levels. For overripe coffee cherries, which are usually purplish-black, the collection net 10 can be placed underneath, the spray pipe 12 can be used to moisten the stalks, the air pipe 13 can be used to blow air, and the vibrator can be used to shake the coffee branches 9. If not all the cherries can be shaken off, the harvesting comb can be used to gently scrape them off. For ripe coffee cherries, which are usually red, the bending force of the harvesting comb can be increased by adjusting the spring while the stalks are still somewhat moist, and controlled to about 1 Newton. If a large number of coffee cherries remain after a single scraping, the angle can be changed and scraped again. As needed, semi-ripe cherries can be harvested, and the force of the harvesting comb can be adjusted to about 2 Newtons. The telescopic rod 8 can be set to pneumatic telescopic, that is, the movement of the telescopic rod 8 is controlled by an air valve, which makes harvesting more labor-saving.

[0047] Example 4:

[0048] like Figure 10 As shown, the drive shaft 1 and / or hinge shaft 3 are both equipped with gears 16. Each row of picking modules 2 is equipped with two or four gears 16. Each gear 16 meshes with the adjacent gear 16, and at least one gear 16 is linked with the reduction motor 17 so that one reduction motor 17 can drive all the gears 16 to rotate. In this way, the chain structure formed by the picking modules 2 can be opened and closed by electric drive.

[0049] Example 5:

[0050] like Figure 10 As shown, the picking module 2 has two hinge holes 20 and one elastic picking finger 21. The elastic picking finger 21 includes an elastic section 27 and a fixed section 28. The elastic section 27 is made of silicone or rubber material and its length can be set to about 30 mm. The elastic modulus of soft rubber is about 7.8 MPa. For picking semi-ripe coffee with a picking force F=2N, the diameter of the elastic section 27 is d≈8.1 mm. For picking ripe coffee with a picking force F=1N, the diameter of the elastic section 27 is d≈6.8 mm. For picking overripe coffee with a picking force F=0.5 N, the diameter of the elastic section 27 is d≈5.7 mm. Rubber is prone to aging and needs to be replaced regularly to ensure that the picking force meets the standard.
