Description

betel nut non-collision receiving device Technical Field

[0001] This utility model relates to the field of areca nut harvesting, and in particular to an areca nut receiving device that prevents collisions. Background Technology

[0002] Areca nut is an evergreen tree belonging to the class Magnoliopsida, order Elementary order, family Arecaceae, and genus Areca. It has an erect, tree-like stem, reaching heights of over 10 meters, sometimes up to 30 meters, with distinct annular leaf scars. It is monoecious, with multi-branched inflorescences. The ovary is oblong, the fruit is oblong or ovoid, and the seeds are ovoid. Flowering and fruiting occur from March to April. Areca trees are 5-12 meters tall, with areca nuts only growing at the top. Due to their height, harvesting is inconvenient. Conventional methods include climbing the tree, tying the areca nuts with ropes, and slowly lowering them down (a dangerous and inefficient method); or standing on the ground and directly cutting the areca nuts with a long-handled cutter, causing them to fall directly to the ground and easily break, resulting in economic losses; or having two people holding sheets or other tools to catch them at the base of the tree, requiring three people and increasing labor costs.

[0003] Therefore, it is necessary to provide a new betel nut receiving device that avoids collisions to solve the above-mentioned technical problems. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a betel nut receiving device that is free from impact.

[0005] The betel nut receiving device provided by this utility model includes: a support handle and a lifting column. The lifting column is placed on top of the support handle. A slot is provided at the top of the lifting column, and a buffer column is slidably connected inside the slot. A fixing frame is fixedly connected to the top of the buffer column. A circular base with a diameter of 40 cm is fixedly connected to the side of the fixing frame away from the lifting column. Five sets of support columns, each 34 cm long, are equidistantly fixed to the side of the circular base away from the lifting column. A connecting rod is fixedly connected to the other end of each support column, and the surface of the connecting rod is covered with a sponge edging. The connecting pole has a diameter of 60 centimeters. When harvesting areca nuts, two people are required to work together. One person uses a 5-10 meter long-handled cutter to cut the connection between the fruit and the tree, while the other person holds the areca nut receiving device and stands 1.5-2 meters under the tree to avoid being injured by falling fruit. The angle and position of the receiving device are adjusted at the base of the tree. The broken branch with the areca nut falls freely from the tree for 5-6 meters and then accurately lands inside the net. The connecting pole is lined with a sponge to reduce the impact of the areca nut hitting the connecting pole during free fall, thus preventing damage to the areca nut and economic losses.

[0006] Preferably, support rods are fixedly connected around the lifting column towards the circular base, and the other end of the support rods is fixedly connected to the bottom of the circular base. The length of the support rods is 23 cm. The installation of support rods facilitates the support of the circular base and ensures the stability of the circular base.

[0007] Preferably, a support notch with a diameter of 20 centimeters is provided on one side of the connecting rod. By providing the support notch, it is convenient to lean against the tree for leverage, reducing the impact force on the support handle when the areca nuts fall, and also making it convenient to stand upright against the tree to carry out other work when not receiving fruit.

[0008] Preferably, a net is fixedly connected to the inside of the connecting rod, and an elastic rope is fixedly connected to the bottom of the net. The other end of the elastic rope is fixedly connected to the support column. The fixed position of the elastic rope is higher than the bottom of the net. By installing the elastic rope, the areca nuts can play a good cushioning role when they fall into the device, preventing damage to the fruit.

[0009] Preferably, a worm gear is rotatably connected to the bottom rear side of the support handle. A worm wheel is meshed with the left side of the worm gear, and a second threaded rod is fixedly connected to the top center of the worm wheel. A lifting column is threadedly connected above the second threaded rod. A rotating shaft is fixedly connected to the right side of the worm gear, and a rocker arm is fixedly connected to the front right side of the rotating shaft. Harvesting areca nuts requires two people working together. One person uses a 5-10 meter long-handled cutter to cut the connection between the fruit and the tree, while the other person holds the areca nut receiving device, stands 1.5-2 meters below the tree, and manually cranks the rocker arm, driving the rotating shaft to rotate, which in turn drives the worm gear, the worm wheel, and the second threaded rod. Because the second threaded rod and the lifting column are threaded together, the lifting column moves upward, increasing the height of the areca nut receiving device. Furthermore, the worm gear and worm wheel form a worm gear-worm structure with a self-locking function. Once the desired height is reached, the support notch is placed against the tree. Depending on the location selected by the cutter, the angle and position of the areca nut receiving device are adjusted at the base of the tree. A branch with areca nuts falls freely from the tree for 5-6 meters before accurately landing inside the net. When not in use, the lifting column can be moved inward by manually cranking the lever, reducing the overall height of the areca nut receiving device, minimizing its footprint, and facilitating storage.

[0010] Preferably, a retainer is fixedly connected to the bottom of the second threaded rod, and a ball bearing is rotatably connected inside the retainer. A lower support frame is placed below the retainer, and an upper support frame is fixedly connected to the top of the lower support frame. When the second threaded rod rotates, it drives the retainer to rotate, causing the ball bearing to rotate inside the lower support frame. This increases the load capacity and rigidity of the second threaded rod and the lifting column, preventing excessive impact from the falling betel nut and damage to the second threaded rod and the lifting column.

[0011] Preferably, a spring is fixedly connected to the bottom of the buffer column, and the bottom end of the spring is fixedly connected to the inside of the slot. When the areca nut falls into the net bag, it will generate a large impact force. The impact force is transmitted to the buffer column through the fixing frame. The buffer column is subjected to downward pressure, which compresses the spring. The elastic potential energy of the spring will absorb part of the impact force, preventing the impact force from being directly transmitted to the frame structure of the entire device, and reducing the risk of vibration and damage to the device.

[0012] Compared with related technologies, the betel nut receiving device without impact provided by this utility model has the following beneficial effects:

[0013] 1. This utility model provides a betel nut receiving device that avoids impact. By installing a net bag, connecting rod and elastic rope, it reduces the impact force of the betel nut falling freely, so as to prevent damage to the betel nut and economic loss. It also saves labor, is safe to operate, and is convenient to carry and use.

[0014] 2. This utility model provides a betel nut receiving device that prevents collisions. By installing a rocker arm, a threaded rod, a lifting rod, and a worm gear, the height of the device can be manually adjusted when picking betel nuts to facilitate receiving them. When not in use, the overall height of the device can be lowered to reduce the floor space occupied and make it easy to store.

[0015] 3. This utility model provides a betel nut impact-free receiving device. By installing a buffer structure, it absorbs part of the impact force generated by the falling betel nut, preventing the impact force from being directly transmitted to the frame structure of the entire device, thus reducing the risk of vibration and damage to the device.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please refer to Figures 1 to 5. This utility model embodiment provides a betel nut receiving device that prevents impact. The device includes a support handle 1 and a lifting column 2. The lifting column 2 is placed on top of the support handle 1. A slot 21 is provided at the top of the lifting column 2. A buffer column 20 is slidably connected inside the slot 21. A fixing frame 11 is fixedly connected to the top of the buffer column 20. A circular base 4 with a diameter of 40 cm is fixedly connected to the side of the fixing frame 11 away from the lifting column 2. Five sets of support columns 10 with a length of 34 cm are equidistantly fixed to the side of the circular base 4 away from the lifting column 2. A connecting rod 5 is fixedly connected to the end. The surface of the connecting rod 5 is covered with a sponge edging. The diameter of the connecting rod 5 is 60 cm. When harvesting areca nuts, two people are required to work together. One person uses a 5-10 meter long-handled cutter to cut the connection between the fruit and the tree, while the other person holds the areca nut receiving device and stands 1.5-2 meters under the tree to avoid being injured by falling objects. The angle and position of the areca nut receiving device are adjusted at the bottom of the tree. The broken branch with the areca nut falls freely from the tree for 5-6 meters and then falls accurately into the net bag 6. The sponge edging on the surface of the connecting rod 5 reduces the impact force when the areca nut hits the connecting rod 5 during free fall, so as to avoid damage to the areca nut and economic loss.

[0025] In the embodiments of this utility model, please refer to Figures 1 and 2. Support rods 3 are fixedly connected around the lifting column 2 in the direction of the circular base 4. The other end of the support rods 3 is fixedly connected to the bottom of the circular base 4. The length of the support rods 3 is 23 cm. By installing the support rods 3, the circular base 4 can be easily supported, ensuring the stability of the circular base 4.

[0026] In the embodiments of this utility model, please refer to Figures 1 and 2. A support notch 7 is provided on one side of the connecting rod 5. The diameter of the support notch 7 is 20 cm. By providing the support notch 7, it is convenient to lean against the tree for leverage, reducing the impact force on the support handle 1 when the areca nuts fall. It is also convenient to stand upright against the tree to carry out other work when not receiving fruit.

[0027] In the embodiments of this utility model, please refer to Figures 1 and 2. A net bag 6 is fixedly connected to the inner side of the connecting rod 5. An elastic rope 19 is fixedly connected to the bottom of the net bag 6. The other end of the elastic rope 19 is fixedly connected to the support column 10. The fixed position of the elastic rope 19 is higher than the bottom of the net bag 6. By installing the elastic rope 19, the areca nut can play a good buffering role when it hits the device, preventing damage to the fruit.

[0028] In this embodiment of the invention, please refer to Figures 2 and 3. A worm gear 12 is rotatably connected to the rear bottom of the support handle 1. A worm wheel 13 is meshed with the left side of the worm gear 12. A second threaded rod 14 is fixedly connected to the top center of the worm wheel 13. A lifting column 2 is threadedly connected above the second threaded rod 14. A rotating shaft 9 is fixedly connected to the right side of the worm gear 12. A rocker arm 8 is fixedly connected to the front right side of the rotating shaft 9. When harvesting areca nuts, two people are required to work together. One person uses a 5-10 meter long-handled cutter to cut the connection between the fruit and the tree, while the other person holds the areca nut receiving device, standing 1.5-2 meters below the tree to avoid being injured by falling debris. Then, they manually crank the rocker arm 8, driving the rotating shaft 9 to rotate, which in turn drives the worm gear 12 to rotate. The worm gear 13 and the second threaded rod 14 rotate. Since the second threaded rod 14 is threadedly connected to the lifting column 2, the lifting column 2 moves upward, raising the height of the areca nut receiving device. Because the worm gear 12 and the worm wheel 13 form a worm gear 13-worm gear 12 structure, it has a self-locking function. After reaching the required height, the support notch 7 is placed against the tree. According to the selected position of the cutter, the angle and position of the areca nut receiving device are adjusted at the bottom of the tree. The broken branch with areca nuts falls freely from the tree for 5-6 meters and then accurately falls into the net bag 6. When not in use, the rocker arm 8 can be manually turned in reverse, causing the lifting column 2 to move into the support handle 1, reducing the overall height of the areca nut receiving device, reducing the footprint, and making it easier to store.

[0029] In the embodiments of this utility model, please refer to Figures 3 and 4. A retainer 16 is fixedly connected to the bottom of the second threaded rod 14. A ball bearing 17 is rotatably connected inside the retainer 16. A lower support frame 18 is placed below the retainer 16. An upper support frame 15 is fixedly connected to the top of the lower support frame 18. When the second threaded rod 14 rotates, it drives the retainer 16 to rotate, causing the ball bearing 17 to rotate inside the lower support frame 18. This increases the load capacity and rigidity of the second threaded rod 14 and the lifting column 2, preventing the impact force from the betel nut from falling too large and causing damage to the second threaded rod 14 and the lifting column 2.

[0030] In the embodiments of this utility model, please refer to Figures 2 and 5. A spring 22 is fixedly connected to the bottom of the buffer column 20. The bottom end of the spring 22 is fixedly connected to the inside of the slot 21. When the areca nut falls into the net bag 6, it will generate a large impact force. The impact force is transmitted to the buffer column 20 through the fixing frame 11. The buffer column 20 is subjected to downward pressure, which compresses the spring 22. The elastic potential energy of the spring 22 will absorb part of the impact force, preventing the impact force from being directly transmitted to the frame structure of the entire device, and reducing the risk of vibration and damage to the device.

[0031] The working principle of the betel nut anti-collision receiving device provided by this utility model is as follows: Two people are needed to cooperate when harvesting betel nuts. One person uses a 5-10 meter long-handled cutter to cut the connection between the fruit and the tree, while the other person holds the betel nut receiving device and stands 1.5-2 meters under the tree to avoid being hit. Then, the person manually cranks the crank lever 8, driving the rotating shaft 9 to rotate, which in turn drives the worm gear 12 to rotate, which in turn drives the worm wheel 13 and the second threaded rod 14 to rotate. Because the second threaded rod 14 is threadedly connected to the lifting column 2, the lifting column 2 moves upward, raising the height of the betel nut receiving device. Furthermore, because the worm gear 14... 2 and worm gear 13 form a worm gear 13 and worm 12 structure, which has a self-locking function. After reaching the required height, the support notch 7 is placed against the tree for easy leverage and to reduce the impact of the falling areca nuts on the support handle 1. The angle and position of the areca nut receiving device are adjusted at the bottom of the tree according to the location selected by the cutter. The broken branch with areca nuts will fall 5-6 meters from the tree and accurately land inside the net bag 6. When not in use, the rocker arm 8 can be manually turned in reverse to move the lifting column 2 into the support handle 1, reducing the overall height of the areca nut receiving device, reducing the floor space, and making it easy to store.
