Description

Technical Field

[0001] This utility model relates to the technical field of lychee picking equipment, and in particular to a portable lychee picking device. Background Technology

[0002] my country is the country of origin for lychees and the world's largest producer. In 2008, my country accounted for 81% of the world's total lychee planting area and 70% of its total output, with an annual output value of 12.8 billion yuan. Lychee has become my country's fourth largest fruit tree. In the planting industries of Guangdong, Guangxi, Fujian, and Hainan provinces (regions), lychee is one of the pillar industries, employing nearly 3 million people and playing an important role in rural employment and harmonious social development. In some parts of my country, the level of agricultural mechanization is very low, and agricultural operations still require a large workforce.

[0003] With the development of science and technology in my country, a number of lychee harvesting equipment technologies have emerged. One existing technology discloses a lychee harvesting pole, with publication number CN210610359U. This pole uses a motor II2 to drive a gear 1, which in turn drives a screw 4 in linear motion, thus moving a slider 6. The slider 6, in conjunction with a hook 8, grips and unloads the fruit stem. By controlling the rotation of motor I1, the blade 7 rotates to cut the lychee stem, simultaneously clamping and cutting. This ensures that when fully clamped, the lychee stem is also severed, increasing harvesting speed. However, this method has drawbacks. Cutting before the lychee stem is clamped causes violent shaking, leading to the lychee falling and breaking. Furthermore, in actual use, the lychee stem may be cut but not yet clamped, causing the entire section to fall and break, affecting fruit quality. Additionally, the hook 8 has a side opening, making it difficult for operators to accurately locate the lychee stem when harvesting from a low position, hindering proper clamping and cutting.

[0016] The beneficial effects of this utility model are as follows: When the opening of the clamping piece is aligned with the lychee stem, the first motor is started, driving the slider upwards. This causes the connecting plate to rise, pushing the spring and lifting rod upwards, thereby causing the left and right clamping pieces to grip the lychee stem inwards. The second motor is then started, driving the cutting blade to rotate. The second motor continues to rotate, driving the slider upwards until the cutting blade cuts the lychee stem and stops. After harvesting, the lychee is placed in the frame. The first motor reverses direction, releasing the lychee. The spring provides cushioning, preventing the left and right clamping pieces, which have already clamped the lychee stem, from continuing to feed and clamp, which could lead to breakage or motor overload. This achieves clamping and cutting while protecting the motor from overload. The upward-facing clamping openings facilitate easy clamping of the lychee stem by technicians operating in the air, improving harvesting efficiency. Attached Figure Description

[0028] Example 1

[0029] See attached document Figure 1-7This application provides a portable lychee picking device, including an execution component, a telescopic rod assembly, and a control component. The execution component is located at one end of the telescopic rod assembly, and the control component is located at the other end of the telescopic rod assembly. The control component is connected to the execution component via a wire. The execution component is used for direct picking of lychees. The telescopic rod assembly acts as a retractable support rod, allowing lychees of different heights to be picked. The control component controls the execution component to perform the lychee picking action. The execution component includes a support 1, a first motor 2, a second motor 3, a cutting blade 4, a slider 5, a lead screw 6, a nut 7, a left clamp 8, a right clamp 9, a connecting rod 10, a lifting rod 11, a spring 12, and a connecting plate 13. The support 1 is fixed to one end of the telescopic rod assembly. The slider 5 is movably connected to the support 1. Sliding can be achieved through a guide rail and a matching slide block, or through a groove and a slide rod. The first motor 2 is mounted on the support 1. The lead screw 6 is rotatably connected to the support 1. The slider 5 has a nut 7 that mates with the lead screw 6; the nut 7 is a lead screw nut. The first motor 2 is driven by the lead screw 6 and electrically connected to the control assembly. The control assembly controls the first motor 2 to start and drive the lead screw 6 to rotate, thereby causing the slider 5 to move linearly. The cutting blade 4 is fixedly connected to the output end of the second motor 3. Mounted on the slider 5, the second motor 3 is electrically connected to the control component. The second motor 3 drives the cutting blade 4 to rotate and cut the branches. The left clamping plate 8 and the right clamping plate 9 are hinged to the support 1 to form a clamp shape. When closed, they clamp the lychee stalk 34. The tail ends of the left clamping plate 8 and the right clamping plate 9 are each hinged to one end of the connecting rod 10. The other end of the connecting rod 10 is hinged to the lifting rod 11. The lifting rod 11 moves forward, driving the connecting rod 10 to move, thereby causing the left clamping plate 8 and the right clamping plate 9 to clamp the lychee stalk 34 inward. Conversely, it releases them, thus achieving the clamping and unloading of the lychee stalk 34. The spring 12 is sleeved on the lifting rod 11. The spring 12 acts as a buffer, so that when the clamping plate (i.e., the left clamping plate 8) is closed, the spring 12 can be used to clamp the lychee stalk 34. When the right clamping piece 9) clamps the lychee stem 34 and the slider 5 continues to rise to cut, the clamping piece remains clamped and does not continue to feed inward, causing the lychee stem 34 to be clamped off. This achieves clamping before cutting, preventing the lychee fruit from shaking and falling off. The lifting rod 11 passes through the connecting plate 13 and is fixed to the slider 5. The lifting rod 11 has limit rings 15 at both the top and bottom. One end of the spring 12 is connected to the connecting plate 13, and the other end is fixed to the limit ring 15 at the upper end of the lifting rod 11. The limit ring 15 at the lower end serves to limit the spring 12 and prevent it from rising and disengaging. During operation, hold the control assembly and the telescopic rod assembly, align the opening of the clamping piece with the lychee stem 34, and start the first motor 2 to drive the slider 5 to move upward.The connecting plate 13 rises, pushing the spring 12 and the lifting rod 11 upwards. This causes the left clamping plate 8 and the right clamping plate 9 to clamp the lychee stalk 34 inwards. The second motor 3 is then activated, driving the cutting blade 4 to rotate. The second motor 3 continues to rotate, driving the slider 5 upwards until the cutting blade 4 cuts the lychee stalk 34 and stops. After harvesting, the lychee is placed in the frame. The first motor 2 moves in the opposite direction, releasing the lychee. During this process, the spring 12 provides cushioning, preventing the left clamping plate 8 and the right clamping plate 9, which have already clamped the lychee stalk 34, from continuing to feed and clamp, which could cause breakage or motor overload. This achieves clamping and cutting while protecting the motor from overload. The upward-facing opening of the clamping plates allows technicians operating in the air to easily align and clamp the lychee stalk 34, improving harvesting efficiency.

[0030] Specifically, the support 1 is provided with a sliding groove 14, and the slider 5 is provided with a slide rail that cooperates with the sliding groove 14. The slider 5 can slide on the support 1 through the cooperation of the sliding groove 14 and the slide rail.

[0031] Specifically, the first motor 2 is connected to a first gear 16, which meshes with a second gear 17. The second gear 17 is fixed to the lead screw 6. The first motor 2 drives the first gear 16 to rotate. The lead screw 6 rotates through the cooperation of the first gear 16 and the second gear 17. The cooperation of the first gear 16 and the second gear 17 achieves speed reduction and torque increase, avoids motor overload, and improves the service life of the motor.

[0032] Example 2

[0033] See attached document Figure 1-7 The difference between this embodiment and embodiment 1 is that the clamping ends of the left clamping piece 8 and the right clamping piece 9 are provided with a number of serrations 18. The serrations 18 are conical. The design of the serrations 18 increases the friction and makes the clamping more stable.

[0034] Specifically, the support 1 is provided with a mounting base 19, and a sensor 20 is installed on the mounting base 19. The sensor 20 is electrically connected to the control component. When the first motor 2 rotates, it drives the slider 5 to move upward until the sensor 20 senses the nut 7. At this time, the sensor 20 feeds back a signal to the control component. After receiving the signal, the control component starts the second motor 3 to drive the cutting blade 4 to rotate and cut, realizing automatic control of the start of the second motor 3. When the first motor 2 stops, the second motor 3 also stops working. The structure is simple and easy to operate.

[0035] Specifically, the support 1 has guide ramps 21 on both inner sides, which are used to guide the lychee stalk 34. The support 1 has a support position 22, which is semi-circular. The guide ramps 21 are connected to the support position 22, so that the lychee stalk 34, after being guided by the guide ramps 21, slides down to the support position 22, thereby achieving the initial positioning of the lychee stalk 34. The structure is simple.

[0036] Specifically, the telescopic rod assembly includes a first support rod 23, a connecting sleeve 24, and a second support rod 25. The outer side of the first support rod 23 is provided with a long thread, and the first support rod 23 is threadedly connected to the connecting sleeve 24. One end of the first support rod 23 is fitted inside the second support rod 25, allowing for free adjustment of the telescopic rod length via a knob. The telescopic rod assembly also includes a hinge rod 32, one end of which is fixed to the support 1, and the other end is hinged to one end of the first support rod 23. This hinge rod is used to adjust the angle of the actuating component and is equipped with an adjusting bolt 33 for locking and adjustment, resulting in a reasonable structure.

[0037] Specifically, the control component includes a grip 26 and a switch button 27. The switch button 27 is located on the outside of the grip 26, and the grip 26 contains a power supply or control circuit board, etc. The first motor 2 is started by controlling the switch button 27.

[0038] Specifically, the grip 26 is equipped with an indicator light 28, which is electrically connected to the power supply and is used to indicate the power level. The structure is simple.

[0039] Specifically, the execution component also includes a first protective cover 29 and a second protective cover 30. The first protective cover 29 is installed on one side of the support 1 to protect the motor, etc. The second protective cover 30 is installed on the other side of the support 1. The second protective cover 30 is provided with an extension plate 31, which supports the lychee fruit to protect it. The structure is simple.

[0040] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
