Description

Technical Field

[0001] This utility model relates to the technical field of coffee bean harvesting devices, specifically to a portable harvesting device. Background Technology

[0002] Coffee beans refer to the fruit of the plant used to make coffee. Broadly speaking, there are two types of coffee beans in the world: Arabica and Robusta. The coffee fruit consists of two oval seeds facing each other. The side that connects them is flat and is called the flat bean.

[0003] Coffee beans need to be harvested after they ripen. The conventional harvesting methods are manual harvesting and mechanical harvesting. Mechanical harvesting is mostly carried out by portable vibrating devices, that is, the harvester drives the tree to vibrate, causing the fully ripe coffee beans to fall down under the vibration. Although this method is very convenient, firstly, the large vibration can loosen the tree root system, and secondly, a single harvesting method may not be suitable for some situations. Therefore, a portable harvesting device is proposed to solve the above-mentioned problems. Utility Model Content

[0004] Based on the above description, this utility model provides a portable harvesting device to solve the problem of the limited harvesting methods of existing vibrating harvesters when harvesting coffee beans.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A portable harvesting device includes: a hinge rod and a harvesting mechanism. The harvesting mechanism is hinged to the hinge rod by tightening screws and includes a mounting housing, a motor, a power gear, a transmission component, a displacement component, and a vibration hook. The power gear is disposed inside the mounting housing and is axially connected to the output of the motor disposed on the outer surface of the mounting housing. The transmission component is disposed inside the mounting housing and meshes with the power gear. It includes a driven gear, a first eccentric disk, a second eccentric disk, and a guide groove. The guide groove is disposed on the opposite side of the first and second eccentric disks. The displacement component is disposed inside the mounting housing and extends into the guide groove. The vibration hook is threadedly connected to the displacement component. A pulsating roller is disposed on the outer surface of the transmission component.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the mounting housing includes a first outer shell and a second outer shell, which are connected to each other by screws.

[0008] Furthermore, each of the first and second outer shells has a movable groove on its opposite side, a guide hole is provided on the upper surface inside the movable groove, and each of the first and second outer shells has a threaded blind hole on its opposite side. The power gear is located inside the movable groove.

[0009] Furthermore, the transmission component includes a rotating rod, which is connected to the first housing via a bearing and extends into the interior of the movable groove.

[0010] Furthermore, a driven gear is provided at one end of the rotating rod near the second housing, the driven gear meshing with the power gear, and a first eccentric disk is provided at one end of the driven gear near the second housing, the first eccentric disk being connected to the second eccentric disk by screws.

[0011] Furthermore, the guide groove is an annular groove, the depth of the inner ring of the guide groove is greater than the depth of the outer ring, the actuating roller includes a roller body, the roller body is connected to the rotating rod by screws, and a Y-shaped actuating piece is provided on the outer surface of the roller body.

[0012] Furthermore, the displacement component includes a guide block disposed inside the guide hole. The guide block has a threaded hole on the side away from the transmission component, and a cylindrical rod and a fixing plate are sequentially disposed on the side of the guide block close to the transmission component.

[0013] Furthermore, the fixing plate extends into the interior of the guide groove, and rollers are provided on both sides of the fixing plate, with the rollers contacting the inner wall of the guide groove.

[0014] Furthermore, the vibration hook includes a hook, which is a C-shaped hook, and the bottom end of the hook is provided with a threaded post, which is adapted to the threaded hole.

[0015] Furthermore, the interior of the movable groove is provided with a guide wheel, the guide wheel including a main wheel, the outer surface of the main wheel is provided with a limiting groove, and the cylindrical rod is in contact with the inner wall of the limiting groove.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0017] 1. This utility model, by setting up components such as a hinge rod, a tightening screw, and a picking mechanism, allows the angle between the hinge rod and the picking mechanism to be adjusted through the cooperation of the hinge rod and the tightening screw. Furthermore, by energizing the picking mechanism, the agitator roller can rotate around the rotating rod as the center. During the rotation, the roller can agitate the coffee bean fruits in a targeted manner, thereby achieving the effect of picking the coffee bean fruits from the tree branches.

[0018] 2. By designing the transmission rod, displacement component, and vibrating hook, a different fruit-picking effect is achieved. When the transmission rod rotates under the drive of the power gear and motor, the first and second eccentric discs rotate around the rotating rod. At this time, the displacement component moves vertically back and forth under the drive of the two eccentric discs, thus achieving the effect of the vibrating hook moving back and forth. During this process, the branches hooked by the vibrating hook vibrate, causing the coffee beans to fall off under the action of vibration. Attached Figure Description

[0035] Example 1

[0036] Please see Figures 1-7 as well as Figure 11 A portable harvesting device, characterized in that it comprises:

[0037] Hinge rod 1; and

[0038] The harvesting mechanism is hinged to the hinge rod 1 by tightening screws 2, and includes a mounting housing 3, a motor 4, a power gear 5, a transmission component 6, a displacement component 7, and a vibration hook 8.

[0039] The mounting housing 3 includes a first outer shell 31 and a second outer shell 32, which are connected to each other by screws. Each of the first outer shell 31 and the second outer shell 32 has a movable groove 34 on its opposite side. A guide hole 35 is provided on the upper surface inside the movable groove 34. Each of the first outer shell 31 and the second outer shell 32 has a threaded blind hole 33 on its opposite side. The power gear 5 is disposed inside the movable groove 34.

[0040] The power gear 5 is disposed inside the mounting housing 3 and is axially connected to the output of the motor 4 disposed on the outer surface of the mounting housing 3;

[0041] The transmission component 6 is disposed inside the mounting housing 3 and meshes with the power gear 5. It includes a driven gear 62, a first eccentric disk 63, a second eccentric disk 64, and a guide groove 65. The transmission component 6 includes a rotating rod 61, which is connected to the first housing 31 via a bearing and extends into the interior of the movable groove 34. A driven gear 62 is disposed at one end of the rotating rod 61 near the second housing 32, and the driven gear 62 meshes with the power gear 5.

[0042] A toggle roller 10 is disposed on the outer surface of the transmission member 6. The toggle roller 10 includes a roller body 101, which is connected to the rotating rod 61 by screws. A Y-shaped toggle piece 102 is disposed on the outer surface of the roller body 101.

[0043] Based on the above, the hinge rod 1 and the mounting housing 3 are hinged to each other. By loosening the tightening screw 2, the angle between the hinge rod 1 and the mounting housing 3 can be adjusted. After adjustment, the tightening screw 2 is tightened again to fix the angle between the hinge rod 1 and the mounting housing 3, which is convenient for users to use.

[0044] When the motor 4 is powered on, it drives the power gear 5 to rotate. At this time, the driven gear 62 drives the rotating rod 61 and the agitator roller 10 to rotate together under the transmission of the power gear 5. When the agitator roller 10 rotates, the Y-shaped agitator 102 makes circular motion. At this time, the agitator roller 10 can come into contact with the coffee bean fruit. The Y-shaped agitator 102 agitates the coffee bean fruit, causing the coffee bean fruit to be separated from the branch by force, thus achieving the effect of picking the fruit.

[0045] Example 2

[0046] Based on Example 1, such as Figures 8-10 As shown, a first eccentric disk 63 is provided at one end of the driven gear 62 near the second housing 32. The first eccentric disk 63 is connected to the second eccentric disk 64 by screws. The guide groove 65 is an annular groove, and the groove depth of the inner ring of the guide groove 65 is greater than the groove depth of its outer ring.

[0047] The displacement member 7 is disposed inside the mounting housing 3 and extends into the guide groove 65. The displacement member 7 includes a guide block 71, which is disposed inside the guide hole 35. A threaded hole 72 is provided on the side of the guide block 71 away from the transmission member 6. A cylindrical rod 73 and a fixing plate 74 are sequentially disposed on the side of the guide block 71 close to the transmission member 6. The fixing plate 74 extends into the guide groove 65. Rollers 75 are provided on both sides of the fixing plate 74, and the rollers 75 are in contact with the inner wall of the guide groove 65.

[0048] Vibration hook 8 is threadedly connected to displacement member 7. Vibration hook 8 includes hook 81, hook 81 is C-shaped hook, and the bottom end of hook 81 is provided with threaded post 82, which is adapted to threaded hole 72.

[0049] The movable groove 34 is provided with a guide wheel 9. The guide wheel 9 includes a main wheel 91. The outer surface of the main wheel 91 is provided with a limiting groove 92. The cylindrical rod 73 is in contact with the inner wall of the limiting groove 92.

[0050] Based on the above, the arrangement of the first eccentric disk 63, the second eccentric disk 64 and the guide groove 65 enables the transmission component 6 to drive the displacement component 7 to make vertical reciprocating motion along the direction of the guide groove 65 when the transmission component 6 rotates. During this process, the roller 75 makes the movement smoother, while the guide wheel 9 increases the smoothness of the displacement component 7 during displacement and also plays a limiting role, so that the displacement component 7 can only move along the direction of the guide groove 65.

[0051] The vibration hook 8 is threadedly connected to the displacement member 7. When the displacement member 7 makes a vertical reciprocating motion, it drives the vibration hook 8 to move together. When the vibration hook 8 is sleeved on the outside of the branch, the rapid reciprocating motion of the vibration hook 8 will cause the branch to vibrate, and the coffee bean fruit will fall off under the action of vibration.

[0052] In both of the above embodiments, the coffee bean fruit is harvested by letting it fall. There are two harvesting methods to meet practical needs, and the fruit can be removed when the vibrating hook 8 is not needed. Since the economic value of the coffee bean fruit is its internal seed, the coffee bean is the main part to be harvested, and the pulp on the surface of the coffee bean is not the part to be used. Therefore, although the above methods, especially the method in embodiment one, may damage the pulp, they will not affect the coffee bean.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
