Description

Technical Field

[0001] This invention relates to the field of blueberry cultivation, and more particularly to a blueberry harvesting auxiliary planting frame with a fruit-preventing net. Background Technology

[0002] Blueberries, a berry crop rich in nutrients, are experiencing a continuous rise in market demand due to their high content of anthocyanins and other nutrients. Small-scale blueberry plantations, with their flexible planting and management models and low initial investment threshold, have secured a certain market share in the blueberry cultivation sector.

[0003] Small-scale blueberry plantations often lack the equipment for large-scale mechanized harvesting, making manual picking the primary method. During manual picking, workers must manually pull the blueberries off their stems. This process is difficult to control precisely, easily causing some ripe berries to fall off. These fallen berries become soiled and lose their commercial value. Furthermore, the labor cost of collecting each fallen berry is high, and growers typically don't collect them, resulting in significant fruit waste and a substantial reduction in the plantation's overall economic benefits.

[0004] Currently, most blueberry growing racks on the market only have basic functions such as supporting plant growth and assisting in shaping, and lack supporting structures for collecting fallen fruit, making it impossible to effectively receive and recycle fallen fruit during the harvesting process.

[0005] To address this technical challenge, there is an urgent need to develop a blueberry planting rack that can be adapted to manual harvesting operations in small-scale plantations and also has the function of preventing fruit drop and collecting the fruit, so as to solve the problem of fruit waste during manual harvesting. Summary of the Invention

[0006] To address the issue that most commercially available blueberry planting racks only provide basic support for plant growth and shaping, lacking a supporting fruit-collecting and anti-drop structure, this invention provides a blueberry harvesting aid planting rack with a fruit-collecting and anti-drop net. This rack offers two working modes: planting rack support and harvesting / collecting, adaptable to both the growth and cultivation stages of blueberry trees and the harvesting stage. Its core design aims to improve the equipment's versatility and practicality, reducing equipment investment costs for small-scale plantations. The planting rack support mode provides stable growth support for the blueberry trees, ensuring robust plant development; the harvesting / collecting mode efficiently catches fallen fruit during manual harvesting, preventing the fruit from becoming soiled and losing its commercial value. Furthermore, the shaking mechanism assists in harvesting, further improving harvesting efficiency.

[0007] The present invention is achieved by the following technical solution: a blueberry picking auxiliary planting frame with a fruit anti-fall net, comprising a planting frame as a whole, the planting frame as a whole including an adaptive adjustment component for adjusting height, a disassembly and assembly separation component installed on the outside of the adaptive adjustment component and used for disassembly and assembly with a multi-functional panel component, an anti-fall net component for receiving fallen blueberries, a support component for supporting the blueberry tree, and a spacing adjustment component for adjusting the distance between the two sets of adaptive adjustment components.

[0008] As a further optimization of the present invention, the adaptive adjustment component includes a base platform, with movable wheels movably connected to the bottom end of the base platform, a connecting column fixedly connected to the outer side of the base platform, and a movable column fixedly connected to the top end of the base platform. A movable boss is slidably connected to the outer wall of the movable column, and an extension block is fixedly connected to the outer wall of the connecting column. A connecting screw is threaded through the surface of the extension block, and a positioning block is fixedly connected to the outer wall of the movable boss. A cylindrical boss is fixedly fixed to the top end of the connecting screw, and the cylindrical boss is movably engaged within the positioning block. A return spring is fixedly connected between the base platform and the movable boss. This structure allows the connecting screw to rotate and move up and down within the threaded hole of the extension block, while the cylindrical boss at its top rotates synchronously within the positioning block, causing the movable boss to move up and down along the movable column. This adapts to blueberry trees of different growth heights. The return spring helps maintain the stability of the movable boss, and the movable wheels at the bottom of the base platform facilitate the overall movement of the planting frame, making it easy to adjust the frame's placement according to the planting location of the blueberry trees, thus improving flexibility.

[0009] As a further optimization of the present invention, the disassembly and assembly assembly includes an upper fixing plate and a lower fixing plate. The upper fixing plate has an upper threaded hole on its side and an upper connecting rod is fixedly installed thereon. The lower fixing plate has a lower connecting hole on its side and a lower threaded rod is fixedly installed thereon. The upper connecting rod slides through the lower connecting hole, and the lower threaded rod is threaded through the upper threaded hole. An upper clamping plate is fixedly connected to the bottom surface of the upper fixing plate, and a lower clamping plate is fixedly connected to the upper surface of the lower fixing plate. Both the upper and lower clamping plates have trapezoidal anti-slip serrations on their clamping surfaces. This design enables quick assembly and disassembly of the multi-functional plate assembly. The trapezoidal anti-slip serrations enhance the connection stability with the positioning plate in the multi-functional plate assembly, preventing loosening and detachment during harvesting operations.

[0010] As a further optimization of the present invention, the multifunctional plate assembly includes a rectangular strip-shaped mounting plate. Positioning plates are integrally forged at both ends of the mounting plate. A groove is formed on the surface of the mounting plate, and a sliding handle is slidably connected within the groove. A boss is fixedly connected to the bottom end of the sliding handle, and the boss slides and engages with the groove. By pushing the sliding handle, the boss at the bottom of the handle slides back and forth along the groove. The sliding handle, through the connecting frame, causes the blueberry bush to shake slightly, prompting ripe blueberries to fall. The fallen berries fall directly into a net bag, achieving efficient fruit collection and preventing the berries from falling to the ground, getting soiled, and losing their commercial value.

[0011] As a further optimization of the present invention, the anti-drop net assembly includes a net frame, a net bag fixedly connected to the inner side of the net frame, a connecting spring frame fixedly connected to the edge of the net frame, and a connecting frame fixedly connected to the outer side of the connecting spring frame. The connecting frame is formed by two sets of arc-shaped frames joined together, and the connecting frame is fixed to the outer wall of the translation handle and the main trunk surface of the blueberry tree, respectively. The connecting spring frame can adjust the unfolding angle of the net frame according to the canopy width of the blueberry tree to ensure that the net bag covers all areas without dead corners, efficiently catches fallen fruit, and at the same time buffers the impact force when the blueberry tree shakes, protecting the plant and the net structure.

[0012] As a further optimization of the present invention, the support assembly is fixedly installed at the top of the movable column. The support assembly includes a connecting seat, a connecting shaft rotatably connected above the connecting seat, one end of a support rod fixedly connected to the outer side of the connecting shaft, and a support frame fixedly connected to the other end of the support rod. The inner surface of the support frame has an arc-shaped structure adapted to the blueberry tree branch. The connecting shaft has a built-in damping structure, and the inner surface of the support frame is bonded with a silicone anti-slip buffer pad with an arc-shaped anti-slip texture. Using the support assembly to support the blueberry tree, the connecting seat is fixed to the top of the movable column. Rotating the support rod allows the damping structure built into the connecting shaft to suspend the support rod at any angle. The operator can adjust the position of the support rod according to the angle of the blueberry tree branch, and then attach the support frame to the main trunk or main branch of the blueberry tree. The silicone anti-slip buffer pad on the inner side of the support frame increases the friction with the branch, preventing the blueberry tree from tipping over, and also provides cushioning protection to prevent the branch from being crushed and damaged.

[0013] As a further optimization of the present invention, the spacing adjustment component includes a first fixed base, a first deflection shaft rotatably connected to the outer side of the first fixed base, one end of a first deflection rod fixedly connected to the outer side of the first deflection shaft, the other end of the first deflection rod rotatably connected to a receiving shaft, one end of a second deflection rod rotatably connected to the outer side of the receiving shaft, and the other end of the second deflection rod rotatably connected to a second deflection shaft, which is fixedly mounted on the second fixed base. The spacing adjustment component is used to connect two sets of adaptive adjustment components, with the first and second fixed bases respectively fixedly mounted on the outer walls of the two sets of base platforms. By adjusting the included angle of the two sets of deflection rods, the spacing between the two sets of adaptive adjustment components can be flexibly changed to adapt to the growth and harvesting needs of blueberry trees with different canopy widths.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention employs a dual-mode design for both planting rack support and harvesting, effectively integrating blueberry tree cultivation and harvesting functions, significantly reducing equipment investment costs for small-scale plantations. In support mode, the equipment can provide stable support to the plants through component adjustments, ensuring robust blueberry tree development; in harvesting mode, it can efficiently collect fruits that fall during manual harvesting, preventing the fruits from becoming soiled and losing their commercial value. The dual-mode switching is convenient, eliminating the need for additional purchases of dedicated support racks and harvesting equipment, greatly saving growers' production costs and site space.

[0016] 2. This invention addresses the industry pain point of easy fruit drop and waste during manual blueberry harvesting through the scientific design of the anti-drop net component. The connecting frame of the anti-drop net component can be fixed to the main trunk of the blueberry tree, and the net bag can completely cover the area under the plant. With the addition of a sliding handle, the plant is gently shaken, which encourages mature fruits to fall into the net bag. Workers can pick the fruits freely, and the fallen fruits naturally fall into the net bag. The net bag can be removed by disassembling the connecting frame to collect the fruits. At the same time, the connecting spring frame effectively buffers the impact of shaking, preventing damage to the blueberry tree branches and trunk, and preventing the net from tearing due to excessive force. This improves the fruit collection rate while protecting the normal growth of the plant.

[0017] 3. This invention possesses excellent adaptability, flexibly meeting the needs of blueberry trees at different growth stages and of different sizes. The adaptive adjustment component allows for precise adjustment of the frame height via rotating a screw, adapting to the height changes of blueberry trees from seedlings to mature plants; the spacing adjustment component allows for flexible adjustment of the spacing between two sets of adaptive adjustment components to match plants with different canopy widths. The damping structure of the support component allows the support rod to be suspended at any angle, and the silicone anti-slip buffer pad conforms to the branches, ensuring support stability while preventing damage to the branches from compression, significantly improving the versatility and service life of the equipment.

[0018] 4. The components of this invention are easy to assemble and disassemble, and the operation is simple, requiring no professional technicians to complete the work, making it suitable for the manpower configuration of small-scale plantations. The upper and lower clamping plates of the disassembly and separation components adopt a trapezoidal anti-slip toothed design, which can quickly achieve disassembly and fixation with the multi-functional plate components, effectively preventing the components from loosening and falling off during operation. The entire equipment is equipped with casters, which makes it easy to flexibly adjust the placement position according to the planting area. During harvesting, pushing the horizontal handle can complete the auxiliary harvesting operation, greatly reducing the difficulty of operation and labor intensity, and improving the overall harvesting efficiency.

[0037] The present invention will now be further described in conjunction with 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.

[0038] Example 1:

[0039] Please combine Figures 1-9 This embodiment proposes a blueberry harvesting auxiliary planting frame with a fruit-preventing net, including a planting frame assembly 1. The planting frame assembly 1 includes an adaptive adjustment component 2 for adjusting the height, a disassembly and assembly separation component 3 installed on the outside of the adaptive adjustment component 2 for disassembly and assembly with the multi-functional board assembly 4, a fruit-preventing net assembly 5 for catching fallen blueberries, a support component 6 for supporting the blueberry tree 8, and a spacing adjustment component 7 for adjusting the distance between the two sets of adaptive adjustment components 2.

[0040] The adaptive adjustment component 2 includes a base platform 21, with a movable wheel 22 movably connected to the bottom end of the base platform 21. A connecting column 23 is fixedly installed on the outer side of the base platform 21, and a movable column 24 is fixedly installed on the top end of the base platform 21. A movable boss 25 is movably installed on the surface of the movable column 24. An extension block 26 is fixedly installed on the surface of the connecting column 23. A positioning block 28 is fixedly installed on the surface of the movable boss 25. A connecting screw 27 is threaded through the surface of the extension block 26. A cylindrical boss is installed at the top end of the connecting screw 27 and is movably engaged inside the positioning block 28. A return spring 29 is fixedly connected between the base platform 21 and the movable boss 25.

[0041] The disassembly and assembly assembly 3 includes an upper fixing plate 31 and a lower fixing plate 32. The upper fixing plate 31 has an upper threaded hole 33 and an upper connecting rod 34 installed on its side. The lower fixing plate 32 has a lower connecting hole 35 and a lower threaded rod 36 installed on its side. The upper connecting rod 34 slides through into the lower connecting hole 35, and the lower threaded rod 36 is threaded through into the upper threaded hole 33. An upper clamping plate 37 is fixedly installed on the bottom surface of the upper fixing plate 31, and a lower clamping plate 38 is fixedly installed on the upper surface of the lower fixing plate 32.

[0042] It should be noted that the clamping surfaces of the upper clamping plate 37 and the lower clamping plate 38 are provided with anti-slip teeth. The teeth have a trapezoidal structure and are used to improve the connection stability between the clamping assembly and the positioning plate 42 in the multi-functional plate assembly 4.

[0043] The specific technical solution involves assembling the components before blueberry harvesting. The positioning plate 42 of the multi-functional board assembly 4 is inserted between the upper clamping plate 37 and the lower clamping plate 38 of the disassembly and reassembly assembly 3. The lower threaded rod 36 is rotated in the opposite direction to tighten it with the upper threaded hole 33, causing the upper connecting rod 34 to slide downwards along the lower connecting hole 35. The upper clamping plate 37 and the lower clamping plate 38 simultaneously clamp the positioning plate 42. The trapezoidal anti-slip teeth on the upper clamping plate 37 and the lower clamping plate 38 enhance the connection stability with the positioning plate 42, preventing the multi-functional board assembly 4 from shaking or falling off during harvesting.

[0044] The multi-functional plate assembly 4 includes a mounting plate 41, which is a rectangular strip plate. The mounting plate 41 has positioning plates 42 integrally forged at both ends. The surface of the mounting plate 41 is provided with a groove 43. A translation handle 44 is slidably installed inside the groove 43. The bottom end of the translation handle 44 is slidably engaged with a boss 45 for sliding inside the groove 43.

[0045] More specifically, during harvesting, the operator pushes the translation handle 44, and the protrusion 45 at the bottom of the translation handle 44 slides back and forth along the groove 43. The translation handle 44, through the connecting frame 54, causes the blueberry bush 8 to shake slightly, causing the ripe blueberries to fall off. The fallen berries fall directly into the net bag 52, achieving efficient collection of the berries and preventing them from falling to the ground and getting dirty, thus losing their commercial value. After the net bag is in place, the staff can carry out the harvesting operation. The fallen berries will fall directly into the net bag 52. The net bag 52 can be removed by disassembling and detaching the connecting frame 54 to collect the berries. The connecting spring frame 53 can buffer the impact of the blueberry bush 8 shaking, preventing damage to the blueberry bush 8, while protecting the structural stability of the anti-fall net assembly 5 and preventing the net from tearing due to excessive shaking.

[0046] The anti-fall net assembly 5 includes a net frame 51, a net bag 52 connected inside the net frame 51, a connecting spring frame 53 fixedly installed on the edge of the net frame 51, and a connecting frame 54 fixedly installed on the outside of the connecting spring frame 53.

[0047] It should be noted that the connecting frame 54 is composed of two sets of arc-shaped frames joined together, and the connecting frame 54 is fixed to the outer wall of the translation handle 44 and the main trunk surface of the blueberry tree 8 respectively.

[0048] The specific technical solution involves connecting the anti-fall net assembly 5 with the multi-functional board assembly 4 and the blueberry tree 8. The two sets of arc-shaped frames of the connecting frame 54 are then closed and fixed to the surface of the sliding handle 44 and the main trunk of the blueberry tree 8, respectively. At this point, the net frame 51 drives the net bag 52 to unfold, completely covering the area below the blueberry tree 8. The connecting spring frame 53 can adjust the unfolding angle of the net frame 51 according to the canopy width of the blueberry tree 8, ensuring that the coverage area of ​​the net bag 52 has no blind spots, facilitating the collection of fallen fruit.

[0049] The spacing adjustment assembly 7 includes a first fixed base 71, a first deflection shaft 72 rotatably connected to the outer side of the first fixed base 71, one end of a first deflection rod 73 connected to the outer side of the first deflection shaft 72, the other end of the first deflection rod 73 connected to a receiving shaft 74, one end of a second deflection rod 75 connected to the outer side of the receiving shaft 74, the other end of the second deflection rod 75 connected to a second deflection shaft 76, and the second deflection shaft 76 mounted on a second fixed base 77.

[0050] Furthermore, the spacing adjustment component 7 is used to connect two sets of adaptive adjustment components 2, with the first fixing seat 71 and the second fixing seat 77 respectively fixedly installed on the surface sidewalls of the two sets of base platforms 21.

[0051] A more specific technical solution involves readjusting the spacing between the two sets of adaptive adjustment components 2 using the spacing adjustment component 7. The operator pushes the two sets of base platforms 21 and adjusts the angles of the first deflection rod 73 and the second deflection rod 75 to change the spacing between the two sets of adaptive adjustment components 2, ensuring that the coverage of the net bag 52 matches the canopy width of the blueberry tree 8 and avoiding collection dead zones.

[0052] Example 2:

[0053] Please see Figure 10 Example 2, based on Example 1, further proposes another type of planting rack support, which can provide stable growth support for blueberry trees and ensure the healthy development of the plants.

[0054] The support assembly 6 is fixedly installed on the top of the movable column 24. The support assembly 6 includes a connecting seat 61, a connecting shaft 62 is rotatably connected to the top of the connecting seat 61, one end of a support rod 63 is fixedly connected to the outside of the connecting shaft 62, and the other end of the support rod 63 is fixedly connected to a support frame 64. The inner surface of the support frame 64 has an arc-shaped structure adapted to the branches of the blueberry tree 8. The connecting shaft 62 has a built-in damping structure, which allows the support rod 63 to rotate around the connecting shaft 62 to any angle and remain suspended.

[0055] It should be noted that the inner side of the support frame 64 is bonded with an anti-slip cushioning pad, which is made of silicone and has an arc-shaped anti-slip texture on the surface.

[0056] Specifically, when the blueberry tree support function is required, the disassembly and assembly separation component 3 needs to be separated from the multi-functional board component 4. The operator can rotate the lower threaded rod 36 to loosen its threaded connection with the upper threaded hole 33. At this time, the upper connecting rod 34 slides upward along the lower connecting hole 35, causing the upper clamping plate 37 to move upward synchronously, creating a gap between the upper clamping plate 37 and the lower clamping plate 38. The positioning plate 42 of the multi-functional board component 4 can then be removed from the gap. After the disassembly is completed, only the disassembly and assembly separation component 3 remains on the adaptive adjustment component 2.

[0057] After disassembly, the height of the planting rack is adjusted using the adaptive adjustment component 2 to accommodate blueberry bushes 8 at different growth heights. The operator rotates the connecting screw 27, which rotates and rises / falls within the threaded hole of the extension block 26. The cylindrical boss at its top rotates synchronously within the positioning block 28, causing the moving boss 25 to rise and fall along the moving column 24. The return spring 29 helps maintain the stability of the moving boss 25, preventing loosening and slippage. The casters 22 at the bottom of the base platform 21 facilitate the overall movement of the planting rack, allowing for easy adjustment of the rack's placement according to the planting location of the blueberry bushes 8.

[0058] The blueberry bush 8 is then supported using the support assembly 6. The connecting seat 61 is fixed to the top of the moving column 24. The support rod 63 is rotated, and the damping structure built into the connecting shaft 62 allows the support rod 63 to be suspended at any angle. The operator can adjust the position of the support rod 63 according to the angle of the branches of the blueberry bush 8. Then, the support frame 64 is fitted against the trunk or main branch of the blueberry bush 8. The silicone anti-slip buffer pad on the inside of the support frame 64 increases the friction with the branches, preventing the blueberry bush 8 from tipping over, and also provides cushioning protection to prevent the branches from being squeezed and damaged.

[0059] Finally, the spacing between the two sets of adaptive adjustment components 2 is adjusted using the spacing adjustment component 7 to accommodate blueberry trees 8 with different canopy widths. The operator can push the two sets of base platforms 21, causing the first deflection rod 73 to rotate around the first deflection axis 72 and the second deflection rod 75 to rotate around the second deflection axis 76. The receiving axis 74 links the two sets of deflection rods to adjust the included angle, thereby changing the spacing between the two sets of adaptive adjustment components 2. This ensures that the support component 6 provides reasonable support for the blueberry tree 8 and improves support stability.

[0060] The working principle of the overall technical solution of this invention:

[0061] This invention features two working modes: a planting rack support mode and a harvesting and collection mode. These modes are adaptable to the growth and cultivation stages of blueberry bushes and the harvesting stages, respectively. The core design objective is to improve the equipment's versatility and practicality, reducing equipment investment costs for small-scale plantations. The planting rack support mode provides stable support for the blueberry bushes, ensuring robust plant development. The harvesting and collection mode efficiently catches fallen fruit during manual harvesting, preventing the fruit from becoming soiled and losing its commercial value. Furthermore, the shaking mechanism assists in harvesting, further improving efficiency.

[0062] I. Working Principle of Planting Rack Support

[0063] When only the blueberry tree support function is required, the disassembly and assembly separation component 3 and the multi-functional board component 4 need to be separated. The operator can rotate the lower threaded rod 36 to loosen its threaded connection with the upper threaded hole 33. At this time, the upper connecting rod 34 slides upward along the lower connecting hole 35, causing the upper clamping plate 37 to move upward synchronously, creating a gap between the upper clamping plate 37 and the lower clamping plate 38. The positioning plate 42 of the multi-functional board component 4 can then be removed from the gap. After the disassembly is completed, only the disassembly and assembly separation component 3 remains on the adaptive adjustment component 2.

[0064] After disassembly, the height of the planting rack is adjusted using the adaptive adjustment component 2 to accommodate blueberry bushes 8 at different growth heights. The operator rotates the connecting screw 27, which rotates and rises / falls within the threaded hole of the extension block 26. The cylindrical boss at its top rotates synchronously within the positioning block 28, causing the moving boss 25 to rise and fall along the moving column 24. The return spring 29 helps maintain the stability of the moving boss 25, preventing loosening and slippage. The casters 22 at the bottom of the base platform 21 facilitate the overall movement of the planting rack, allowing for easy adjustment of the rack's placement according to the planting location of the blueberry bushes 8.

[0065] The blueberry bush 8 is then supported using the support assembly 6. The connecting seat 61 is fixed to the top of the moving column 24. The support rod 63 is rotated, and the damping structure built into the connecting shaft 62 allows the support rod 63 to be suspended at any angle. The operator can adjust the position of the support rod 63 according to the angle of the branches of the blueberry bush 8. Then, the support frame 64 is fitted against the trunk or main branch of the blueberry bush 8. The silicone anti-slip buffer pad on the inside of the support frame 64 increases the friction with the branches, preventing the blueberry bush 8 from tipping over, and also provides cushioning protection to prevent the branches from being squeezed and damaged.

[0066] Finally, the spacing between the two sets of adaptive adjustment components 2 is adjusted using the spacing adjustment component 7 to accommodate blueberry trees 8 with different canopy widths. The operator can push the two sets of base platforms 21, causing the first deflection rod 73 to rotate around the first deflection axis 72 and the second deflection rod 75 to rotate around the second deflection axis 76. The receiving axis 74 links the two sets of deflection rods to adjust the included angle, thereby changing the spacing between the two sets of adaptive adjustment components 2. This ensures that the support component 6 provides reasonable support for the blueberry tree 8 and improves support stability.

[0067] II. Working Principle of Harvesting and Collection

[0068] Before blueberry harvesting, the components must be assembled. The positioning plate 42 of the multi-functional board assembly 4 is inserted between the upper clamping plate 37 and the lower clamping plate 38 of the disassembly and reassembly assembly 3. The lower threaded rod 36 is rotated in the opposite direction to tighten it with the upper threaded hole 33, causing the upper connecting rod 34 to slide downwards along the lower connecting hole 35. The upper clamping plate 37 and the lower clamping plate 38 simultaneously clamp the positioning plate 42. The trapezoidal anti-slip teeth on the upper clamping plate 37 and the lower clamping plate 38 enhance the connection stability with the positioning plate 42, preventing the multi-functional board assembly 4 from shaking or falling off during harvesting.

[0069] Connect the anti-fall net assembly 5 to the multi-functional board assembly 4 and the blueberry tree 8. Close the two sets of arc-shaped frames of the connecting frame 54 and fix them to the surface of the sliding handle 44 and the main trunk of the blueberry tree 8, respectively. At this time, the net frame 51 drives the net bag 52 to unfold, completely covering the area under the blueberry tree 8. The connecting spring frame 53 can adjust the unfolding angle of the net frame 51 according to the canopy width of the blueberry tree 8 to ensure that the coverage area of ​​the net bag 52 has no blind spots, making it easy to catch fallen fruits.

[0070] The distance between the two sets of adaptive adjustment components 2 is adjusted again by the distance adjustment component 7. The operator pushes the two sets of base platforms 21 and adjusts the angle of the first deflection rod 73 and the second deflection rod 75 to change the distance between the two sets of adaptive adjustment components 2, so as to ensure that the coverage of the net bag 52 matches the canopy of the blueberry tree 8 and avoid the occurrence of collection dead corners.

[0071] During harvesting, the operator pushes the translation handle 44, and the protrusion 45 at the bottom of the translation handle 44 slides back and forth along the groove 43. The translation handle 44, through the connecting frame 54, causes the blueberry bush 8 to shake slightly, causing the ripe blueberries to fall off. The fallen berries fall directly into the net bag 52, achieving efficient collection of the berries and preventing them from falling to the ground and getting dirty, thus losing their commercial value. After the net bag is in place, the staff can carry out the harvesting operation. The fallen berries will fall directly into the net bag 52. The net bag 52 can be removed by disassembling and detaching the connecting frame 54 to collect the berries. The connecting spring frame 53 can buffer the impact of the blueberry bush 8 shaking, preventing damage to the blueberry bush 8, and at the same time protect the structural stability of the anti-fall net assembly 5, preventing the net from tearing due to excessive shaking.
