Technical Field
[0001] This utility model relates to the field of fruit harvesting technology, and in particular to a fruit harvester for fruit trees. Background Technology
[0002] Fruit harvesters, as an important component of modern agricultural mechanization, have a development history closely linked to the actual needs of the fruit tree planting industry. With the rapid development of the global fruit industry, especially in my country, a major fruit-producing country with a leading position in both planting area and yield, the demand for efficient and high-quality fruit harvesting is increasing daily.
[0003] Existing fruit harvesters are mainly mechanical harvesters based on vibration principles. These harvesters struggle to ensure uniformity and integrity when harvesting fruits of varying shapes and sizes. Vibration harvesting can also easily damage the fruit, and many harvesters are unsuitable for environments with varying heights. Furthermore, fruit collection carries the risk of fruit damage. Therefore, a fruit harvester specifically designed for fruit trees is proposed. Utility Model Content
[0004] The present invention aims to solve the technical problem of how to simultaneously collect and prevent drop when picking fruits from fruit trees at different heights, and provides a fruit picker for fruit trees.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A fruit harvester for fruit trees includes a telescopic rod, a connecting rod, a harvesting device, a storage device, a shock absorption device, and a controller.
[0007] The connecting rod is horizontally positioned on the upper side of the telescopic rod, and one end of the connecting rod is fixedly connected to the upper end of the telescopic rod.
[0008] The harvesting device is located on the side of the connecting rod away from the telescopic rod, and the side of the harvesting device is fixedly connected to the other end of the connecting rod.
[0009] The storage device is located below the harvesting device and to the side of the telescopic rod, with the top of the storage device fixedly connected to the bottom of the harvesting device.
[0010] The shock-absorbing device is located below the storage device and to the side of the telescopic rod, and is connected to the storage device.
[0011] The controller is located on the side of the telescopic pole, and its back is fixedly connected to the side of the telescopic pole. The controller is electrically connected to the telescopic pole and the harvesting device, respectively.
[0012] When fruit needs to be harvested, staff members approach the fruit tree, hold the lower end of the telescopic pole, and use the controller to extend the pole. The extension of the pole raises the connecting rod, which in turn raises the harvesting device. The harvesting device then raises the collecting device, which in turn raises the shock-absorbing device. This continues until the appropriate height is reached. The controller is then used to stop the extension of the telescopic pole. The staff member then moves the harvesting device to the outside of the fruit, places the fruit inside the collecting device, and uses the controller to activate the harvesting device. The harvesting device cuts the fruit stem, and the fruit falls into the collecting device, where it is cushioned and protected by the shock-absorbing device.
[0013] Furthermore, the harvesting device includes a fixed frame, two slides, a forward and reverse motor, a double threaded rod, two slide bars, and two blades.
[0014] The fixing frame is horizontally positioned on the side of the connecting rod, and the side of the fixing frame is fixedly connected to the connecting rod.
[0015] Two sliding grooves are arranged horizontally and parallel to the connecting rod, and the two sliding grooves are located on both sides of the fixed frame.
[0016] The forward and reverse motor is located on the outside of the fixed frame and on the side of the fixed frame closer to the connecting rod. The side of the forward and reverse motor is closer to the side of the fixed frame with the sliding groove, and the side of the forward and reverse motor is fixedly connected to the side of the fixed frame.
[0017] The double threaded rod is arranged horizontally and parallel to the connecting rod. The double threaded rod is located inside the fixed frame and on the side of the forward and reverse motor away from the telescopic rod. The double threaded rod is fixedly connected to the forward and reverse motor.
[0018] Two sliding rods are arranged horizontally and perpendicular to the connecting rod. The two sliding rods are set inside the two sliding grooves and are located on the side of the forward and reverse motor away from the telescopic rod. The two sliding rods are slidably connected to the double threaded rod, and the sliding direction is parallel to the axis of the double threaded rod. The bottom of the two ends of the two sliding rods are in close contact with the top surface of the two sliding grooves.
[0019] Two blades are arranged horizontally and parallel to two slide bars. The two blades are located inside two slide grooves and on the side of the slide bars away from the forward and reverse motors. One end of each blade is fixedly connected to the side of the two slide bars, and the bottom of each blade is in close contact with the top surface of the two slide grooves.
[0020] When the harvesting device is needed to pick the fruit, the staff first moves the fixed frame to the outside of the fruit. The fruit is then placed inside the receiving device, with only the fruit stem exposed inside the fixed frame. Then, the controller is used to turn on the forward and reverse motors. The forward and reverse motors drive the double threaded rod to rotate. The rotation of the double threaded rod causes the two sliding rods to slide into the middle of the two sliding grooves. The sliding of the two sliding rods into the middle of the two sliding grooves causes the two blades to slide into the middle of the two sliding grooves. Finally, the two blades contact the fruit stem and cut it off, and the fruit harvesting is completed.
[0021] Furthermore, the storage device includes a support frame, four guide pillars, a storage bag, and a support plate.
[0022] The support frame is horizontally positioned below the fixed frame, and the top of the support frame is fixedly connected to the bottom of the fixed frame.
[0023] Four guide posts are vertically spaced below the fixed frame, located at the four corners of the fixed frame, with the tops of the four guide posts fixedly connected to the bottom of the fixed frame.
[0024] The storage bag is positioned below the support frame and between the four guide pillars, with the top of the storage bag fixedly connected to the bottom of the support frame.
[0025] The support plate is horizontally positioned below the storage bag and is fitted over the four guide posts. The support plate is slidably connected to the four guide posts, and its sliding direction is vertical.
[0026] When the fruit is harvested and needs to be stored, it falls into the storage bag. The support plate supports the bottom of the storage bag, cushioning and reducing the impact of the falling fruit to prevent damage. The guide post guides the movement of the support plate to prevent it from tilting, and the support frame fixes the top of the storage bag to maintain its shape and prevent the fruit from falling.
[0027] Furthermore, the shock absorption device includes four fixed blocks and four springs.
[0028] Four fixing blocks are respectively set at the bottom of the four guide posts, and the top of the four fixing blocks is fixedly connected to the bottom of the four guide posts.
[0029] Four springs are respectively positioned above the four fixed blocks and below the support plate. The four springs are respectively sleeved on the outside of the four guide posts, and the bottoms of the four springs are respectively fixedly connected to the four fixed blocks.
[0030] When the fruit falls into the storage bag, the support plate moves downward due to the impact of the fruit. The downward movement of the support plate compresses the spring, which in turn compresses the fixing block. The fixing block provides support to the spring, and the spring provides cushioning and shock absorption for the support plate.
[0031] Furthermore, the telescopic pole is made of fiberglass material.
[0032] Fiberglass materials have high strength, which can meet the strength requirements of equipment, and are relatively lightweight, which helps to reduce the burden on workers. Fiberglass also has good insulation properties, which improves the safety of equipment.
[0033] Furthermore, the blades are made of ceramic.
[0034] Ceramic blades have extremely high hardness, allowing the blade to maintain its sharpness for a long time. They also have good chemical stability, meaning they will not react with acidic substances in fruits or cause metal contamination. In addition, ceramic blades are very lightweight, which helps reduce the burden on workers.
[0035] The beneficial effects of this utility model are:
[0036] 1. This utility model achieves height adjustment of the equipment by setting up a telescopic rod, a picking device, a storage device, and a shock absorption device, which is suitable for picking fruits of different heights. At the same time, it completes the storage, and the storage device can effectively prevent the fruits from falling. The shock absorption device can buffer and protect the falling fruits to prevent them from being damaged. Attached Figure Description

[0040] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model.
[0041] like Figure 1-2 As shown, the technical solution adopted by this utility model to solve its technical problem is:
[0042] A fruit harvester for fruit trees includes a telescopic rod 1, a connecting rod 3, a harvesting device, a storage device, a shock absorption device, and a controller 2.
[0043] The connecting rod 3 is horizontally positioned on the upper side of the telescopic rod 1, and one end of the connecting rod 3 is fixedly connected to the upper end of the telescopic rod 1.
[0044] The picking device is located on the side of the connecting rod 3 away from the telescopic rod 1, and the side of the picking device is fixedly connected to the other end of the connecting rod 3.
[0045] The storage device is located below the picking device and to the side of the telescopic rod 1. The top of the storage device is fixedly connected to the bottom of the picking device.
[0046] The shock-absorbing device is located below the storage device and to the side of the telescopic rod 1, and is connected to the storage device.
[0047] The controller 2 is located on the side of the telescopic rod 1. The back of the controller 2 is fixedly connected to the side of the telescopic rod 1. The controller 2 is electrically connected to the telescopic rod 1 and the harvesting device respectively.
[0048] When fruit needs to be picked, the staff comes to the foot of the fruit tree, holds the lower end of the telescopic pole 1, and uses the controller 2 to extend the telescopic pole 1. The extension of the telescopic pole 1 causes the connecting rod 3 to rise, which in turn raises the picking device. The rising of the picking device then raises the storage device, which in turn raises the shock-absorbing device until the appropriate height is reached. The staff then uses the controller 2 to stop the extension of the telescopic pole 1. The staff then moves the picking device to the outside of the fruit, puts the fruit into the storage device, and uses the controller 2 to activate the picking device. The picking device cuts the fruit stem, and the fruit falls into the storage device, where it is cushioned and protected by the shock-absorbing device.
[0049] The harvesting device includes a fixed frame 8, two sliding grooves 9, a forward and reverse motor 4, a double threaded rod 7, two sliding rods 5, and two blades 6.
[0050] The fixing frame 8 is horizontally arranged on the side of the connecting rod 3, and the side of the fixing frame 8 is fixedly connected to the connecting rod 3.
[0051] Two sliding grooves 9 are arranged horizontally and parallel to the connecting rod 3. The two sliding grooves 9 are located on both sides of the fixed frame 8.
[0052] The forward and reverse motor 4 is located on the outside of the fixed frame 8 and on the side of the fixed frame 8 closer to the connecting rod 3. The side of the forward and reverse motor 4 is close to the side of the fixed frame 8 with the sliding groove 9. The side of the forward and reverse motor 4 is fixedly connected to the side of the fixed frame 8.
[0053] The double threaded rod 7 is arranged horizontally and parallel to the connecting rod 3. The double threaded rod 7 is located inside the fixed frame 8 and is on the side of the forward and reverse motor 4 away from the telescopic rod 1. The double threaded rod 7 is fixedly connected to the forward and reverse motor 4.
[0054] Two sliding rods 5 are arranged horizontally and perpendicular to the connecting rod 3. The two sliding rods 5 are located inside the two sliding grooves 9 and are on the side of the forward and reverse motor 4 away from the telescopic rod 1. The two sliding rods 5 are slidably connected to the double threaded rod 7 respectively. The sliding direction is parallel to the axis of the double threaded rod 7. The bottom of both ends of the two sliding rods 5 are in close contact with the top surface of the two sliding grooves 9 respectively.
[0055] Two blades 6 are arranged horizontally and parallel to the two slide rods 5. The two blades 6 are located inside the two slide grooves 9 and are on the side of the slide rods 5 away from the forward and reverse motors 4. One end of the two blades 6 is fixedly connected to the side of the two slide rods 5 respectively, and the bottom of the two blades 6 is in close contact with the top surface of the two slide grooves 9 respectively.
[0056] When the harvesting device is needed to harvest the fruit, the staff first moves the fixed frame 8 to the outside of the fruit. The fruit is placed inside the storage device, with only the fruit stem exposed inside the fixed frame 8. Then, the controller 2 is used to turn on the forward and reverse motor 4. The forward and reverse motor 4 drives the double threaded rod 7 to rotate. The rotation of the double threaded rod 7 drives the two slide rods 5 to slide between the two slide grooves 9. The sliding of the two slide rods 5 to the two slide grooves 9 drives the two blades 6 to slide between the two slide grooves 9. Finally, the two blades 6 contact the fruit stem and cut it off, and the fruit harvesting is completed.
[0057] The storage device includes a support frame 10, four guide pillars 11, a storage bag 12, and a support plate 13.
[0058] The support frame 10 is horizontally positioned below the fixed frame 8, and the top of the support frame 10 is fixedly connected to the bottom of the fixed frame 8.
[0059] Four guide posts 11 are vertically spaced below the fixed frame 8, located at the four corners of the fixed frame 8, and the tops of the four guide posts 11 are fixedly connected to the bottom of the fixed frame 8.
[0060] The storage bag 12 is located below the support frame 10 and in the middle of the four guide posts 11. The top of the storage bag 12 is fixedly connected to the bottom of the support frame 10.
[0061] The support plate 13 is horizontally positioned below the storage bag 12 and is fitted over the four guide posts 11. The support plate 13 is slidably connected to the four guide posts 11, and its sliding direction is vertical.
[0062] When the fruit harvest is complete and needs to be stored, the fruit falls into the storage bag 12. The support plate 13 supports the bottom of the storage bag 12, cushioning and damping the falling fruit to prevent damage. The guide post 11 guides the movement of the support plate 13 to prevent it from tilting. The support frame 10 fixes the top of the storage bag 12 to maintain its shape and prevent the fruit from falling.
[0063] The shock absorption device includes four fixed blocks 15 and four springs 14.
[0064] Four fixing blocks 15 are respectively set at the bottom of the four guide posts 11, and the top of the four fixing blocks 15 is fixedly connected to the bottom of the four guide posts 11.
[0065] Four springs 14 are respectively positioned above the four fixed blocks 15 and below the support plate 13. The four springs 14 are respectively sleeved on the outside of the four guide posts 11, and the bottom of the four springs 14 are respectively fixedly connected to the four fixed blocks 15.
[0066] When the fruit falls into the storage bag 12, the support plate 13 moves downward due to the impact of the fruit. The downward movement of the support plate 13 compresses the spring 14, and the spring 14 is compressed and squeezed by the fixing block 15. The fixing block 15 provides support for the spring 14, and the spring 14 buffers and reduces shock on the support plate 13.
[0067] Telescopic pole 1 is made of fiberglass material.
[0068] Fiberglass materials have high strength, which can meet the strength requirements of equipment, and are relatively lightweight, which helps to reduce the burden on workers. Fiberglass also has good insulation properties, which improves the safety of equipment.
[0069] Both blades are made of ceramic.
[0070] Ceramic blades have extremely high hardness, allowing the blade to maintain its sharpness for a long time. They also have good chemical stability, meaning they will not react with acidic substances in fruits or cause metal contamination. In addition, ceramic blades are very lightweight, which helps reduce the burden on workers.
[0071] Working principle: When fruit needs to be harvested, the worker comes to the foot of the fruit tree, holds the lower end of the telescopic pole 1, and uses the controller 2 to extend the telescopic pole 1. The extension of the telescopic pole 1 causes the connecting rod 3 to rise, and the rising of the connecting rod 3 causes the fixed frame 8 to rise until the appropriate height is reached. The worker then uses the controller 2 to stop the extension of the telescopic pole 1. The worker then moves the fixed frame 8 to the outside of the fruit, puts the fruit into the storage bag 12, leaving only the fruit stem exposed inside the fixed frame 8. The worker uses the controller 2 to turn on the forward and reverse motor 4, which drives the double threaded rod 7 to rotate. The rotation of the double threaded rod 7 causes the two sliding rods 5 to slide into the middle of the two sliding grooves 9. The sliding of the two sliding rods 5 into the middle of the two sliding grooves 9 causes the two blades 6 to slide into the middle of the two sliding grooves 9. Finally, the two blades 6 contact the fruit stem and cut it off, and the fruit harvesting is completed.
[0072] When the fruit is harvested and stored, it falls into the storage bag 12. The support plate 13 supports the bottom of the storage bag 12. The spring under the compression support plate 13 cushions and dampens the falling fruit to prevent damage. The guide post 11 guides the movement of the support plate 13 to prevent it from tilting. The support frame 10 fixes the top of the storage bag 12 to maintain its shape and prevent the fruit from falling.
[0073] When the fruit falls into the storage bag 12, the support plate 13 moves downward due to the impact of the fruit. The downward movement of the support plate 13 compresses the spring 14, and the spring 14 is compressed and squeezed by the fixing block 15. The fixing block 15 provides support for the spring 14, and the spring 14 buffers and reduces shock on the support plate 13.
[0074] The above embodiments are only some embodiments of this utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the protection scope of this utility model.
