Technical Field
[0001] This utility model belongs to the field of wolfberry harvesting devices, and in particular relates to a biomimetic hand-grip portable wolfberry harvesting device. Background Technology
[0002] Goji berries, belonging to the Solanaceae family, are red fruits renowned for their rich nutritional and medicinal value. With increasing health awareness, market demand for goji berries is constantly growing, leading to increased planting and sales, and making a significant contribution to the agricultural economy of planting areas. Goji berries have become an important pillar of the agricultural economy in planting areas such as Ningxia. However, current goji berry harvesting techniques have many shortcomings, severely restricting the further development of the goji berry industry. Traditional harvesting methods mostly rely on manual picking, which is inefficient, costly, and labor-intensive. While mechanized harvesting technology has developed, existing mechanical harvesting equipment suffers from inconvenience, low efficiency, and high loss rates.
[0003] A search revealed that Chinese utility model patent CN223094270U discloses a goji berry harvesting device. While its vibration-type harvesting improves efficiency, it causes a higher damage rate to the goji berries. Although the comb-type harvesting has a lower damage rate, it is less efficient than the vibration-type. While intelligent harvesting machines can harvest precisely, they are costly and difficult to popularize. In addition, the special growing environment and harvesting methods of goji berries result in high manufacturing and maintenance costs for mechanical harvesting equipment, which limits its large-scale application. Utility Model Content
[0004] The purpose of this utility model is to provide a biomimetic hand-grabbing portable goji berry harvesting device to solve the technical problems of low efficiency, high cost and high labor intensity of manual harvesting, as well as the inconvenience, low harvesting efficiency and high loss rate of existing mechanical harvesting equipment.
[0005] To achieve the above objectives, the specific technical solution of this utility model for a biomimetic hand-grip portable goji berry harvesting device is as follows:
[0006] A biomimetic hand-grip portable goji berry harvesting device includes two opposing housings; a handle is fixedly mounted on one side of each housing; a motor is installed inside each housing; a first bevel gear is fixedly connected to the motor shaft; a second bevel gear is rotatably mounted on one side of the housing opposite the first bevel gear; the first and second bevel gears are meshed together; a drive gear is attached to the second bevel gear extending towards the opposing housing and connected via a spline; an eccentric wheel is rotatably mounted on one side of the housing opposite the drive gear; the drive gear and the eccentric wheel are meshed together; a harvesting claw is rotatably mounted vertically and vertically at the end of the housing away from the handle; a transmission link is rotatably connected to one end of the harvesting claw inside the housing; one transmission link is rotatably connected to the middle of another transmission link, and the other transmission link is rotatably connected to the eccentric shaft of the eccentric wheel; a collection device is bolted to one side of the housing opposite the harvesting claw.
[0007] Furthermore, the two sides of the housing are provided with multiple guide posts; the two sides of the housing are connected at the positions of the multiple guide posts by bolts.
[0008] Furthermore, the housing is provided with multiple reinforcing ribs; each of the multiple reinforcing ribs is provided with a mounting groove relative to the motor; the motor is disposed in the mounting groove.
[0009] Furthermore, an arc-shaped support plate is provided at the end of the handle away from the housing.
[0010] Furthermore, a limiting sleeve is provided at the connection position between the motor shaft and the bevel gear.
[0011] Furthermore, a soft rubber sleeve is provided around the outer side of the claw portion at the end furthest from the shell of the picking claw.
[0012] Furthermore, the collection device is equipped with a filter screen with holes at its opening.
[0013] Furthermore, the housing is provided with a slot relative to the handle; the handle is provided with a buckle extending into the housing relative to the slot.
[0014] This utility model discloses a biomimetic hand-grip portable goji berry harvesting device with the following advantages: Through the coordinated arrangement of multiple structures, a motor drives a second bevel gear via a first bevel gear, which in turn drives an eccentric wheel via a drive gear. Simultaneously, the eccentric wheel's rotation causes two transmission linkages to actuate the connected harvesting claws, which reciprocate a certain distance on the casing. Driven by the motor, the two harvesting claws create a biomimetic slapping motion. By adjusting the motor power, the slapping frequency of the harvesting claws is made close to the modal frequency of the goji berry branches, causing the goji berries to resonate and fall into the collection device. This achieves efficient harvesting of goji berries with minimal damage. The device has a simple structure and is easy to manufacture and maintain. The design is low-cost and lightweight, allowing for handheld use and facilitating large-scale application. A soft rubber sleeve surrounds the outer side of the picking claw, effectively reducing damage to the branches and fruits during harvesting by tapping the branches, achieving low-loss harvesting and improving fruit quality. A collection device with a perforated filter screen is located on one side of the casing opposite the picking claw. When workers tap and vibrate the fruit during harvesting, the filter screen removes branches and leaves that fall along with the goji berries, allowing only the berries to pass through the screen into the collection device. This prevents debris from entering the collection device and increasing the workload for subsequent sorting. Attached Figure Description

[0022] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a biomimetic hand-grip portable goji berry harvesting device.
[0023] like Figure 1-6 As shown, this utility model discloses a biomimetic hand-grip portable goji berry harvesting device, comprising two opposing housings 1; a handle 2 is fixedly mounted on one side of each housing 1; a motor 3 is installed inside each housing 1; a first bevel gear 4 is fixedly connected to the shaft of the motor 3; a second bevel gear 5 is rotatably mounted on one side of the housing 1 opposite to the first bevel gear 4; the first bevel gear 4 and the second bevel gear 5 are meshed together; the second bevel gear 5 extends towards the opposite housing 1 and is connected to a drive gear 6 via a spline; an eccentric part is rotatably mounted on the housing 1 opposite to the drive gear 6. Wheel 7; drive gear 6 and eccentric wheel 7 are meshed; a picking claw 8 is provided at the end of housing 1 away from handle 2, rotating vertically; a transmission link 9 is rotatably connected to one end of the picking claw 8 inside housing 1; one transmission link 9 is rotatably connected to the middle of another transmission link 9, and the other transmission link 9 is rotatably connected to the eccentric shaft of eccentric wheel 7; a collecting device 10 is provided on one side of housing 1 opposite to the picking claw 8 by bolts; a slot 18 is provided on housing 1 opposite to handle 2; a buckle 19 is provided on handle 2 opposite to slot 18, extending into housing 1.
[0024] Combination Figure 1-6As shown, during use, the operator holds the handle 2 of the device and positions the picking claws 8 opposite the goji berry branches to be picked. Simultaneously, the collecting device 10 is positioned opposite the goji berry branches. The motor 3 is then started, and its shaft drives the first bevel gear 4 to rotate. Simultaneously, the motor 3 drives the second bevel gear 5 through the first bevel gear 4. The second bevel gear 5 drives the drive gear 6, which is splined to drive the eccentric wheel 7 to rotate. The rotation of the eccentric wheel 7 simultaneously drives the two transmission rods 9, causing the picking claws 8 to reciprocate a certain distance on the housing 1. Driven by the motor 3, the two picking claws 8 form a biomimetic striking motion. By adjusting the power of the motor 3, the striking frequency of the picking claws 8 is made close to the modal frequency of the goji berry branches, causing the goji berries on the branches to resonate and fall into the collecting device 10. This achieves efficient harvesting of goji berries with minimal damage. The device has a simple structure, low manufacturing and maintenance costs, and is lightweight and handheld, making it suitable for large-scale application.
[0025] Combination Figure 2-5 As shown, multiple guide posts 11 are arranged opposite each other on both sides of the housing 1. The two sides of the housing 1 are connected by bolts at the positions of the multiple guide posts 11. Multiple reinforcing ribs 12 are provided inside the housing 1. The multiple reinforcing ribs 12 are provided with mounting grooves 13 opposite to the motor 3. The motor 3 is set in the mounting groove 13. A limiting sleeve 15 is provided at the connection position between the motor 3 shaft and the bevel gear. The guide posts 11 arranged opposite each other on the two housing 1 can play a guiding role when the housing 1 is installed. At the same time, during use, the multiple guide posts 11 can provide support for the side walls of the two housing 1. Together with the multiple reinforcing ribs 12 provided inside the housing 1, the overall strength of the housing 1 is increased. Through the setting of the mounting grooves 13 on the reinforcing ribs 12, the two sides of the housing 1 form a limiting and fixed position of the motor 3 through the mounting grooves 13, which increases the stability of the motor 3 during use. At the same time, together with the limiting sleeve 15 provided on the outside of the motor 3 shaft, the rotation state of the motor 3 shaft is stabilized during operation.
[0026] Combination Figure 1-4 As shown, an arc-shaped support plate 14 is provided at the end of the handle 2 away from the housing 1. When the worker needs to hold this device to harvest goji berries, the worker holds the handle 2, and the arc-shaped support plate 14 at the end of the handle 2 away from the housing 1 fits against the worker's forearm and elbow. The arc-shaped support plate 14 forms a lever support effect for this device, distributing the weight of the worker's hand. During long-term use, it can significantly reduce the fatigue of the worker's arm, reduce the shaking of the worker's hand, increase the stability and accuracy of operation, and effectively prevent occupational injuries from long-term work.
[0027] Combination Figure 1As shown, a soft rubber sleeve 16 is provided around the outer side of the claw part away from the shell 1 of the picking claw 8. By providing a soft rubber sleeve 16 around the outer side of the picking claw 8, the relatively soft rubber sleeve 16 can effectively reduce damage to the wolfberry branches and fruits when the picking claw 8 is patting the wolfberry branches for picking, so as to achieve the purpose of low-damage picking and improve the quality of the fruit.
[0028] Combination Figure 1 As shown, the collection device 10 is equipped with a perforated filter screen 17 at its opening. By using the perforated filter screen 17 on one side of the housing 1 opposite to the picking claw 8, when the staff uses this device to tap and vibrate to pick the goji berries, the filter screen 17 filters out the branches and leaves that fall down along with the goji berries when the picking claw 8 is tapped, allowing only the goji berries to pass through the holes of the filter screen 17 into the collection device 10, preventing debris from entering the collection device 10 and increasing the workload of subsequent sorting.
[0029] When workers use this device to harvest goji berries, if they operate with one hand, they can collect the fallen goji berries by fixing the collection device 10 to the outside of the housing 1 relative to the harvesting claw 8. If workers are harvesting with both hands, they can remove the collection device 10 from the outside of the housing 1, operate the device with one hand to beat the goji berry branches, and hold the collection device 10 with the other hand to collect the fallen goji berries. This makes the operation more flexible and adaptable to a variety of different harvesting scenarios.
