Abstract
Description
Technical Field
[0001] This utility model relates to the field of fruit picking technology, and in particular to a lemon picker. Background Technology
[0002] Lemons are woody plants belonging to the Rutaceae family and the Citrus genus. Their fruits are oval or egg-shaped with a thick, lemon-yellow peel. Lemons are not only edible but also have high medicinal value. Specialized harvesting equipment is needed to pick lemons after they ripen.
[0003] Chinese utility model patent CN222655796U discloses an organic fruit harvesting device. This device uses a dual-axis motor to rotate two unidirectional threaded rods. During rotation, these rods push two L-shaped blocks closer together, which in turn pull two cutting blades closer together. When the cutting blades approach and contact each other, they sever the fruit stem connecting the fruit to the branch, allowing the fruit to fall into a collection assembly, thus completing the harvesting of individual fruits. Regarding the aforementioned technology, the inventors believe the following drawbacks exist: In actual use, as the number of fruits in the collection components increases, the overall weight of the device also increases, making it more difficult for the user to hold. To solve this problem, the user needs to put the device down, remove the collected fruits, and then lift the device up to continue using it. This is not only troublesome but also reduces the efficiency of fruit picking. Therefore, we provide a lemon picker. Utility Model Content
[0004] To address the inconvenience caused by the need for users to frequently put down the device to remove fruit and then pick it up again to continue using it in order to reduce the weight of the device, this utility model provides a lemon picker.
[0005] This utility model is achieved using the following technical solution: a lemon picker, comprising a vertical rod, a tubular handle end movably connected to the lower outer side of the vertical rod, a first ring fixedly connected to the top of the vertical rod, a fixed blade fixedly connected to one side of the top of the first ring, an electric push rod fixedly connected to the other side of the top of the first ring, a movable blade fixedly connected to the telescopic end of the electric push rod, a second ring fixedly sleeved on the outside of the vertical rod, a net fixedly connected to the bottom of the second ring, and a first spring sleeved on the outside of the vertical rod.
[0006] As a further improvement to the above solution, a pin hole 1 is provided at the upper and lower parts of the vertical rod, and a pin hole 2 is provided at the end of the tubular handle. The same pin shaft is inserted into the pin hole 1 and pin hole 2 on the same side. A connecting plate is fixedly connected to the end of the pin shaft. A spring 2 is sleeved on the outside of the pin shaft, and the two ends of the spring 2 are fixedly connected to the end of the tubular handle and the connecting plate, respectively.
[0007] As a further improvement to the above solution, two sets of limiting protrusions are symmetrically fixedly connected to the outside of the vertical rod, and two sets of limiting grooves are symmetrically opened on the inner side of the tubular handle end, and the limiting grooves are slidably connected to the limiting protrusions on the same side.
[0008] As a further improvement to the above solution, the two ends of the spring one are fixedly connected to the ring two and the tubular handle end, respectively.
[0009] As a further improvement to the above solution, both the fixed blade and the movable blade are fixedly connected to a baffle by a bracket.
[0010] As a further improvement to the above solution, a flexible pad is fixedly connected to the top of the baffle.
[0011] As a further improvement to the above solution, a storage battery is also fixedly connected to the ring, and a control switch is fixedly connected to the outside of the tubular handle end. The storage battery, the control switch, and the electric push rod are all electrically connected by wires.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. After the lemons are collected in the net bag, the connecting plate is released, and the pin automatically pops out of the pin hole due to the rebound of the second spring. The net bag automatically descends and compresses the first spring by utilizing the movable cooperation between the vertical rod and the tubular handle end, making it easy to quickly retrieve the lemons inside. Once all the lemons have been removed, the net bag automatically rises back to its original position due to the rebound of the first spring. This effectively avoids the inconvenience of existing devices that require users to frequently lower and remove the device and then lift it again to continue using it in order to reduce the device's weight. This invention is highly practical.
[0013] 2. In this invention, when the electric push rod pushes the movable blade closer to the fixed blade to harvest lemons, the movement of the movable blade also moves the baffle fixedly connected to it via the bracket. When the movable blade contacts the fixed blade and cuts the lemon branch, the baffle contacts another baffle to catch the lemon and provide cushioning. When the electric push rod drives the movable blade to reset, the lemon will automatically fall into the net bag, thus preventing damage from the lemon falling directly onto the previously collected lemons after harvesting. The flexible pad improves the protection of the lemons, and the closed baffle covers the top opening of the net bag, preventing lemons from falling when the net bag descends, further improving the practicality of the device.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example
[0017] Please combine Figure 1-3This embodiment of a lemon picker includes a vertical rod 1. A tubular handle end 2 is movably connected to the lower outer side of the vertical rod 1. A ring 3 is fixedly connected to the top of the vertical rod 1. A fixed blade 4 is fixedly connected to one side of the top of the ring 3. An electric push rod 5 is fixedly connected to the other side of the top of the ring 3. A movable blade 6 is fixedly connected to the telescopic end of the electric push rod 5. A ring 7 is fixedly fitted on the outside of the vertical rod 1. A net bag 8 is fixedly connected to the bottom of the ring 7. A spring 9 is fitted on the outside of the vertical rod 1. The two ends of the spring 9 are fixedly connected to the ring 7 and the tubular handle end 2, respectively. Pin holes 10 are opened at the upper and lower parts of the vertical rod 1. A pin hole 2 is opened on the tubular handle end 2. A pin is inserted into the pin hole 10 and the pin hole 2 on the same side. There is a common pin 11, and a connecting plate 12 is fixedly connected to the end of the pin 11. A spring 13 is sleeved on the outside of the pin 11, and the two ends of the spring 13 are fixedly connected to the tubular handle end 2 and the connecting plate 12 respectively. Two sets of limiting protrusions 14 are symmetrically fixedly connected to the outside of the vertical rod 1. Two sets of limiting grooves are symmetrically opened on the inner side of the tubular handle end 2, and the limiting grooves are slidably connected to the limiting protrusions 14 on the same side, which can play a certain guiding role for the vertical movement of the vertical rod 1. Baffles 15 are fixedly connected to the fixed blade 4 and the movable blade 6 through brackets. A storage battery is also fixedly connected to the ring 3. A control switch is fixedly connected to the outside of the tubular handle end 2. The storage battery, the control switch and the electric push rod 5 are all electrically connected through wires.
[0018] The implementation principle of a lemon harvester in this embodiment is as follows: When in use, the device is lifted so that the lemon branch is positioned between the fixed blade 4 and the movable blade 6. The electric push rod 5 is activated via a control switch. The electric push rod 5 pushes the movable blade 6 closer to the fixed blade 4 to harvest the lemon. The movement of the movable blade 6 also moves the baffle 15, which is fixedly connected to the support, along with the movable blade 6. When the movable blade 6 contacts the fixed blade 4 and cuts the lemon branch, the baffle 15 contacts another baffle 15 to cushion the lemon. When the electric push rod 5 drives the movable blade 6 to reset, the lemons will automatically fall into the net bag 8. This prevents the lemons from being damaged by falling directly onto the previously collected lemons after harvesting. Because the gap between the baffle 15 and the ring 3 is small enough, the lemons will not fall outside the net bag 8 through the gap. When the net bag 8 has collected a certain number of lemons and the device becomes difficult to operate, by grasping the bottom of the vertical rod 1 and releasing the connecting plate 12, the spring 13 will rebound, causing the lemons to fall back into the net bag 8. The pin 11 automatically pops out of the pin hole, and through the movable cooperation between the vertical rod 1 and the tubular handle end 2, the net bag 8 automatically and stably descends and compresses the spring 9, making it easy to quickly retrieve the lemons inside. When the net bag 8 descends to its lowest point, pressing the connecting plate 12 presses the pin 11 into the pin hole, thus fixing the net bag 8 and preventing it from rising automatically to facilitate retrieving the lemons. By placing the bottom end of the vertical rod 1 on the ground for support, the user's hand fatigue can be reduced. If the weight of the lemon is insufficient to lower the net bag 8 to its lowest point... When in the low position, the vertical rod 1 can be manually pulled down to continue moving the net bag 8 downwards. After all the lemons inside the net bag 8 have been removed, the connecting plate 12 is released again. The spring 9's own rebound action causes the net bag 8 to automatically rise and reset. This effectively avoids the inconvenience caused by the existing device requiring users to frequently lower and remove the device and then lift it up again to continue using it in order to reduce the weight of the device. When the net bag 8 rises to the highest position, simply press the connecting plate 12 again to fix the net bag 8 for continued harvesting. Example
[0019] This embodiment is an improvement on embodiment 1, in that a flexible pad 16 is fixedly connected to the top of the baffle 15, which can improve the protection of the lemon.
[0020] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
