Description

Technical Field

[0001] This utility model relates to the field of forestry planting technology, and in particular to a seedling straightening and reinforcement device for forestry planting. Background Technology

[0002] In forest cultivation, the growth of seedlings is affected by environmental factors such as wind force, soil looseness, and rainfall, which often cause seedlings to tilt or fall over during their growth. The uprightness of seedlings is crucial for their healthy growth, especially in the seedling stage. Tilting or falling over not only affects their photosynthesis but may also lead to poor root development, ultimately affecting their survival rate. Therefore, timely and effective seedling straightening is an important link to ensure seedling growth and improve the success rate of forest cultivation.

[0003] Patent application number CN202420696192.3 discloses a novel seedling straightening device, comprising: a base, on which a scissor lifting mechanism is provided, the scissor lifting mechanism including at least one set of scissor arms, each set of scissor arms including two rotatably connected moving arms that cross each other, the moving arms including a lower arm body located below the intersection point and an upper arm body located above the intersection point; and a clamping straightening component, the clamping straightening component including a first clamping arm and a second clamping arm, the two lower arms respectively equipped with the first clamping arm and the second clamping arm, and the two upper arms respectively equipped with the first clamping arm and the second clamping arm. This straightening device can more flexibly adapt to seedlings of different diameters and shapes, and ensures that the clamping force is evenly and stably distributed. Operating the scissor lifting mechanism allows the clamping straightening component to rise and fall freely, and ensures that the first and second clamping arms can directly clamp the seedlings while rising and falling, which can better straighten seedlings of different heights and thicknesses and ensure the straightening effect. These types of straightening devices mostly use rigid clamps, such as clamps, to fix the seedlings. Because the stress is concentrated in one place, the rigid mechanical clamps can cause the seedling bark to wear down or even die. In addition, when the seedlings are subjected to external impact, the wear between the clamps and the seedlings will also be aggravated, so improvements are needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a seedling straightening and reinforcement device for forestry planting, which overcomes the shortcomings of existing devices.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a seedling straightening and reinforcement device for forestry planting, comprising:

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a seedling straightening and reinforcement device for forestry planting, including:

[0031] Two sleeves 1 are placed one above the other, with their axes coinciding;

[0032] Two arc-shaped sleeves 4 are set inside the sleeve 1 to protect the main trunk of the seedling;

[0033] Multiple elastic support members 5 are arranged in an array between the sleeve 1 and the arc-shaped clamp 4 to support the arc-shaped clamp 4 so that the arc-shaped clamp 4 can compress the main trunk of the seedling.

[0034] The hoop 1 is fitted on the outside of the seedling. The arc-shaped clamp 4 is pushed by the elastic support 5 to squeeze the seedling. With the help of the adjusting support leg 3 on the connecting plate 2, the seedling is straightened and supported. When the seedling is affected by external force and causes an overload impact on the arc-shaped clamp 4, the elastic support 5 will disperse the impact force on the arc-shaped clamp 4 through deformation, so as to avoid excessive local pressure on the arc-shaped clamp 4 and damage to the seedling and equipment. Moreover, the two hoop 1 are placed one above the other, which can make the seedling more evenly stressed when supported, and the structural strength is higher.

[0035] At least three connecting plates 2 are arranged in an array between two sleeves 1, and the upper and lower ends of the connecting plates 2 are fixedly connected to the two sleeves 1 respectively.

[0036] Adjustable support leg 3, the upper end of adjustable support leg 3 is hinged to connecting plate 2, and the lower end of adjustable support leg 3 is provided with anti-slip part.

[0037] The connecting plate 2 is fixedly installed between the two sleeves 1 to connect the two sleeves 1 into a whole. Each connecting plate 2 has an adjustable support leg 3 on its outer side. By setting at least three adjustable support legs 3, the sleeves 1 are stably supported. The height of the sleeves 1 can be adjusted by using the adjustable support legs 3, thereby meeting the support needs of seedlings of different heights and having wide applicability.

[0038] Specifically, the sleeve 1 includes two arc-shaped clamp plates 11. One end of the arc-shaped clamp plate 11 is hinged to one end of the other arc-shaped clamp plate 11 by a cylindrical pin 12. The other end of the arc-shaped clamp plate 11 is provided with a bolt seat 13. The bolt seat 13 is fixedly connected to the arc-shaped clamp plate 11. A fixing bolt 14 is mounted on the bolt seat 13. The fixing bolt 14 is threadedly connected to the bolt hole opened on the bolt seat 13.

[0039] The upper and lower ends of the connecting plate 2 are respectively fixed to two sets of arc-shaped hoop plates 11. During installation, the fixing bolts 14 mounted on the bolt seat 13 are unscrewed from the bolt holes. After the fixing between the two arc-shaped hoop plates 11 is released, the arc-shaped hoop plates 11 can be opened and placed on the outside of the seedling. After the installation is completed, the bolt seat 13 can be fixed again.

[0040] Each arc-shaped clamp 11 is equipped with a corresponding arc-shaped sleeve 4, which includes a silicone sleeve 42. An arc-shaped sleeve 41 is fitted on the outside of the silicone sleeve 42 and is fixedly connected to the silicone sleeve 42. Multiple vertical ribs 43 are provided on the opposite sides of the two arc-shaped sleeves 41 and are fixedly connected to the arc-shaped sleeves 41. The arc-shaped sleeve 4 is connected to the arc-shaped clamp 11 through an elastic support 5. The silicone sleeve 42 can unfold as the arc-shaped clamp 11 unfolds. When the arc-shaped clamp 11 is locked, the arc-shaped sleeves 41 on the silicone sleeve 42 will reinforce the seedling from both sides under the support of the elastic support 5. The silicone sleeve 42 can play a buffering role, and the vertical ribs 43 fixed on the outside of the arc-shaped sleeves 41 can increase the friction between the arc-shaped sleeves 41 and the seedling, resulting in a higher tightening effect.

[0041] The elastic support 5 is used in conjunction with the arc-shaped sleeve 4. Specifically, the elastic support 5 includes a spring rod 51, a spring 52, and a limiting nut 53. The spring rod 51 is fixedly connected to the side of the silicone sleeve 42 away from the vertical rib 43. The end of the spring rod 51 away from the silicone sleeve 42 passes through the arc-shaped hoop 11. The arc-shaped hoop 11 is slidably connected to the spring rod 51. The spring 52 is sleeved on the outside of the spring rod 51. The left and right ends of the spring 52 are fixedly connected to the silicone sleeve 42 and the arc-shaped hoop 11, respectively. The arc-shaped hoop 11 has a through groove that works with the spring rod 51. When the arc-shaped sleeve 41 is compressed, the spring rod 51 will slide outward along the through groove on the arc-shaped hoop 11 under the push of the arc-shaped sleeve 41. The spring 52 between the silicone sleeve 42 and the arc-shaped hoop 11 will contract and rebound after the compression ends. The spring rod 51, through frictional contact with the arc-shaped hoop 11, works with the spring 52 to absorb the impact force on the arc-shaped sleeve 41, thus protecting the seedlings and the arc-shaped sleeve 41.

[0042] To prevent the spring rod 51 from separating from the arc-shaped clamp plate 11, a limiting nut 53 is provided at the end of the spring rod 51 away from the spring 52, and the limiting nut 53 is fixedly connected to the spring rod 51. By providing the limiting nut 53 at the end of the spring rod 51, the spring rod 51 can be prevented from falling off the arc-shaped clamp plate 11.

[0043] The adjustable support leg 3 is the supporting part of the reinforcement device. Specifically, the adjustable support leg 3 includes a sleeve 31 and an adjusting rod 32. The upper end of the sleeve 31 is hinged to the connecting plate 2, and the upper end of the adjusting rod 32 is inserted into the inside of the sleeve 31. The sleeve 31 and the adjusting rod 32 are slidably connected. A fastening mechanism for locking the adjusting rod 32 is provided on the outside of the sleeve 31. By controlling the locking between the sleeve 31 and the adjusting rod 32 through the fastening mechanism, the adjusting rod 32 can be slid to adjust the overall height of the sleeve 31 and the adjusting rod 32, thereby meeting the straightening and reinforcement needs of seedlings of different heights.

[0044] The fastening mechanism uses bolt positioning to lock the adjusting rod 32. Specifically, the fastening mechanism includes an adjusting bolt 35, which is mounted on the outside of the sleeve 31. The adjusting bolt 35 is screwed into the sleeve 31 and threadedly connected to the positioning hole 34 on the outside of the adjusting rod 32. The adjusting rod 32 has multiple positioning holes 34 on its outside, which are evenly distributed along the length of the adjusting rod 32. By rotating the adjusting bolt 35, the adjusting bolt 35 is unscrewed from the positioning hole 34, allowing the adjusting rod 32 to slide up and down. After adjustment, the adjusting bolt 35 is rotated in the opposite direction to screw it into the corresponding positioning hole 34, completing the secondary locking of the adjusting rod 32.

[0045] An anti-slip part is located at the bottom of the adjustable outrigger 3 to ensure that the adjustable outrigger 3 will not slip when supported, thus improving stability. In a preferred embodiment, the anti-slip part includes a puncture cone 33, which is fixedly connected to the lower end of the adjusting rod 32. The puncture cone 33 is an inverted Y-shaped fork. The two branches on the Y-shaped fork can provide support in different directions, forming a more stable three-point support structure, reducing the risk of swaying or tipping due to uneven ground, and better adapting to uneven ground.

[0046] How this application works:

[0047] The clamp 1 is fitted onto the outside of the seedling. The arc-shaped sleeve 4, pushed by the elastic support 5, compresses the seedling. Together with the adjusting legs 3 on the connecting plate 2, it straightens and supports the seedling. When the seedling is subjected to external force, causing an overload impact on the arc-shaped sleeve 4, the elastic support 5 will disperse the impact force through deformation, preventing excessive local pressure on the arc-shaped sleeve 4 and damage to the seedling and equipment. Furthermore, the two clamps 1 are placed vertically, ensuring more even force distribution on the seedling during support. The connecting plate 2 is fixedly positioned between the two clamps 1. Each connecting plate 2 has an adjusting leg 3 on its outer side. By setting at least three adjusting legs 3, the clamps 1 are stably supported. The height of the clamps 1 can be adjusted using the adjusting legs 3, thus meeting the support needs of seedlings of different heights, making it widely applicable.
