Description

Technical Field

[0001] This invention relates to the field of forestry seedling technology, and in particular, to a protective cover for cultivating forestry seedlings. Background Technology

[0002] Seedlings, also known simply as saplings, are a general term for various fruit tree seedlings, arbor seedlings, and shrub seedlings. A seedling is a sapling with roots and a trunk. All seedlings cultivated in a nursery, regardless of age, before being released from the nursery, are called seedlings. Forestry protection, in addition to protecting existing trees, also involves planting new trees on barren land. Before this, the cultivation and protection of seedlings is necessary. During the seedling cultivation process, protective clamps, using adhesive strips, expand outwards synchronously with the growing seedlings within the rings, thus... The protective cover serves to support and protect the sapling. As the sapling grows thicker and longer inside the protective cover, it gradually rises and pushes the inner rubber strip, causing it to roll up in the same direction as the back of the protective cover. This causes the protective cover to press against the curved back of the protective cover, locking and stopping the sapling's tendency to sway in the direction of its growth. The cover then fastens to the outside of the sapling at a certain angle with the rubber strip, or even inserts into the outside of the sapling, thus inhibiting the sapling's growth and reducing the protective effect of the cover on the cultivation of forestry saplings. Summary of the Invention

[0003] To address the above problems, the present invention provides a protective cover for forestry seedling cultivation, the structure of which includes a main insert frame, a fixed frame, a cover body, an outer ring, and a lifting platform. The main insert frame is connected to the lower part of the outer ring, the fixed frame is connected inside the outer ring, the lifting platform is sleeved at the bottom of the fixed frame, and the cover body is installed inside the fixed frame. The cover includes an assembly clamp, a protective clamp, a docking sleeve, an assisting element, and an adhesive strip. The docking sleeve is connected to the inside of the fixing frame through the assembly clamp, and the protective clamp is connected inside it. An assisting element is provided between the protective clamp and the adhesive strip.

[0004] As a further improvement of the present invention, the assistive body includes a surrounding strip, a folded tube, a supporting structure, a slack ring, and a swing rod. The surrounding strip and the slack ring are connected to one end of the swing rod, and both ends of the swing rod are connected to the folded tube. A supporting structure is provided between the folded tube and the surrounding strip.

[0005] As a further improvement of the present invention, the folded tube is movably engaged under the protective clamp by a swing rod, and its folded structure will roll outward synchronously with the adhesive strip, which helps to expand the frame to limit the adhesive strip while merging into a ring.

[0006] As a further improvement of the present invention, the receiving structure includes a fixed base, a docking component, an opening and closing clamp, a swing handle, and a connecting rod. The fixed base is connected between the folding tube and the connecting rod. The bottom of the connecting rod is connected to the swing handle and is connected to the outside of the surrounding strip. The opening and closing clamp is connected inside the swing handle, and the docking component is installed between the opening and closing clamps.

[0007] As a further improvement of the present invention, the docking component includes a sleeve frame, a pressure block, an arch bar, a gripper, and a push handle. The pressure block is connected inside the sleeve frame, and the gripper is connected outside the sleeve frame. The gripper and the push handle are slidably engaged inside the opening and closing clamp. The pressure block is connected to the arch bar, and the arch bar is interference-fitted above the connecting rod.

[0008] As a further improvement of the present invention, the hysteresis ring includes a roller, an arc frame, an adjusting member, a bracket, and a support rod. The roller is slidably fitted inside the surrounding strip through the support rod. The support rod and the swing rod are connected to the outside of the arc frame. The adjusting member is installed between the arc frames through the bracket.

[0009] As a further improvement of the present invention, the insert is connected to one end of the arc frame, and through the interference fit between the arc frame and the rubber strip, it can rotate the adjusting component towards the inside of the arc frame while the arc frame is pulled together by the swing rod.

[0010] As a further improvement of the present invention, the adjusting component includes a through rod, a strap, an abutment plate, and a retaining plate. The through rod and the retaining plate are connected inside the abutment plate by the strap. The strap is interference-fitted above the abutment plate. The abutment plate is rotatably fitted inside the arc frame and the insert. Beneficial effects

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention features an assistive element inside the cover. This assistive element works in conjunction with the protective clamp and the rubber strip. When the sapling grows inside the connecting sleeve, it first pushes and grinds the rubber strip, causing the rubber strip to roll and arch upwards from the inside out under the assistance element. This allows the assistive element to be pushed together and layered in the same direction, preventing the rubber strip from excessively rolling and adhering to the back of the protective clamp. It also pries the protective clamp in the opposite direction to smoothly expand and swing outwards, making it suitable for continuously growing saplings. During the cultivation period, it achieves a highly efficient support and protection function, ensuring the protective effect of the protective cover on the cultivation of forestry saplings.

[0012] This invention incorporates a receiving structure and a stagnation ring within the assisted body. The receiving structure and stagnation ring work together on the surrounding strip. As the growing sapling gradually expands and pushes against the rubber strip, the middle of the strip begins to bend and roll outwards. This causes the swing rod to pull the surrounding strip and folded tube together into a circular shape. The stagnation ring can then be pushed outwards to lock the further rolling of the rubber strip. Furthermore, the receiving structure is evenly distributed between the surrounding strip and folded tube, allowing it to overlap the outside of the sapling and the inside of the protective clamp. This allows for multi-point prying of the protective clamp, directional outward expansion and swaying, making it better suited for protecting saplings during their cultivation period.

[0013] Because the docking parts move up and down between the swing handles, the present invention can push the swing handles to flatten and fix them to the outside of the slats, which can maintain the rigidity of the circular structure of the slats when they are stretched and closed, and facilitate the connection of the connecting rods from the inside out and the prying into the protective clamp.

[0014] This invention allows the arc frame to swing in sync with the closing of the swing arm and retract synchronously. It can work with the insert to drive the adjustment piece at the other end of the frame to rotate inward. The swinging adjustment piece vertically stores force and bends, which can resist the further curling and arching of the middle of the rubber strip. Attached Figure Description

Detailed Implementation

[0023] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0024] like Figures 1-3 As shown, this invention provides a protective cover for forestry seedling cultivation. Its structure includes a main insert 3, a fixing frame 1, a cover body 2, an outer ring 4, and a lifting platform 5. The insert 3 is fixedly connected to the lower part of the outer ring 4. The fixing frame 1 is welded to the inside of the outer ring 4. The lifting platform 5 is fitted onto the bottom of the fixing frame 1, and the cover body 2 is installed inside it. The cover body 2 includes an assembly clamp 2a, a protective clamp 2s, a connecting sleeve 2d, an assisting body 2f, and a rubber strip 2g. The connecting sleeve 2d is threadedly connected to the inside of the fixing frame 1 via the assembly clamp 2a, and the protective clamp 2s is hinged to its inside. An assisting body is provided between the protective clamp 2s and the rubber strip 2g. The body 2f includes a surrounding strip 2f1, a folded tube 2f2, a supporting structure 2f3, a delay ring 2f5, and a swing rod 2f4. The surrounding strip 2f1 and the delay ring 2f5 are fixedly connected to one end of the swing rod 2f4. Both ends of the swing rod 2f4 are welded to the folded tube 2f2. Two or more supporting structures 2f3 are provided between the folded tube 2f2 and the surrounding strip 2f1. The folded tube 2f2 is movably engaged below the protective clamp 2s by the swing rod 2f4, and its folded structure will roll outward synchronously with the adhesive strip 2g, which helps to expand the frame and limit the adhesive strip 2g while merging into a ring. The cover 2 has an assistive body 2f inside, which utilizes the assistive body 2f to... The force body 2f works in conjunction with the protective clamp 2s and the rubber strip 2g. When the sapling grows within the connecting sleeve 2d, it will first push and grind against the rubber strip 2g, causing the rubber strip 2g to roll and arch upwards from the inside out under the assistance body 2f. This allows the assistance body 2f to be pushed together and layered in the same direction, not only preventing the rubber strip 2g from excessively rolling and adhering to the back of the protective clamp 2s, but also prying the protective clamp 2s in the opposite direction to smoothly expand and swing outwards. This is convenient for the continuously growing saplings and achieves a highly efficient supporting and protective function during the cultivation period, ensuring the protective cover's protective effect on forestry sapling cultivation. A supporting structure 2f3 and a buffer ring 2f5 are installed inside the assistance body 2f. By utilizing the supporting structure 2f3 and the retardant ring 2f5 in conjunction with the surrounding strip 2f1, as the growing sapling gradually expands outward and pushes against the running-in strip 2g, the middle of the running-in strip 2g will begin to bend and roll outward. This will cause the swing rod 2f4 to pull the surrounding strip 2f1 and the folded tube 2f2 to stretch and converge into a circular shape. It can also push the retardant ring 2f5 outward to further roll the strip 2g, and cause the supporting structure 2f3 to be evenly distributed between the surrounding strip 2f1 and the folded tube 2f2. It can then overlap to the outside of the sapling and the inside of the protective clamp 2s. It can pry the protective clamp 2s at multiple points to expand and swing outward in a directional manner, making it more suitable for protecting saplings during the cultivation period. Example 2

[0025] like Figures 4-7As shown, based on Embodiment 1, the present invention incorporates the following structural components in cooperation: the receiving structure 2f3 includes a fixed base f32, a docking piece f33, an opening and closing clamp f34, a swing handle f35, and a connecting rod f31. The fixed base f32 is fixedly connected between the folding tube 2f2 and the connecting rod f31. The bottom of the connecting rod f31 is hinged to the swing handle f35 and inserted into the outside of the surrounding strip 2f1. The opening and closing clamp f34 is sleeved inside the swing handle f35. The docking piece f33 is installed between the opening and closing clamps f34. The docking piece f33 includes a sleeve frame 33z, a pressure block 33x, an arch 33c, a gripper 33v, and a push handle. 33b, a pressure block 33x is internally connected to the sleeve frame 33z, and a gripper 33v is fixedly connected to its exterior. The gripper 33v and the push handle 33b are slidably engaged inside the opening and closing clamp f34. The pressure block 33x is welded to the arch strip 33c, and the arch strip 33c is interference-fitted above the connecting rod f31. The slack ring 2f5 includes a roller f51, an arc frame f53, an adjusting component f54, a bracket f52, and a support rod f55. The roller f51 is slidably engaged inside the surrounding strip 2f1 through the support rod f55. The support rod f55 and the swing rod 2f4 are fixedly connected to the exterior of the arc frame f53. The arc frames f53 are connected by the bracket f52. An adjusting component f54 is installed. The insert f52 consists of two triangular structures of different sizes, which are sleeved and connected to one end of the arc frame f53. The arc frame f53 is press-fitted with the rubber strip 2g. When the arc frame f53 is pulled together by the swing rod 2f4, the insert f52 can rotate the adjusting component f54 towards the inside of the arc frame f53. The adjusting component f54 includes a through rod 54m, a strap 54n, a contact plate 54b, and a locking plate 54v. The through rod 54m and the locking plate 54v are fixedly connected to the inside of the contact plate 54b by the strap 54n. The strap 54n is press-fitted above the contact plate 54b. The contact plate 54b... The rotating fit is inside the arc frame f53 and the insert f52. As the connecting piece f33 moves up and down between the swing handle f35, it can push the swing handle f35 to flatten and fix it to the outside of the wrap strip 2f1. This can maintain the rigidity of the circular structure of the wrap strip 2f1 when it is stretched and closed, making it easy to push the connecting rod f31 from the inside out to overlap and pry it into the protective clamp 2s. The arc frame f53 can swing and close synchronously with the swing rod 2f4. It can cooperate with the insert f52 to drive the adjusting piece f54 at the other end to rotate into the arc frame f53. The swinging adjusting piece f54 is vertically bent by stored force, which can resist the further rolling and arching of the middle of the rubber strip 2g.

[0026] The working principle of one of the protective covers for forestry seedling cultivation in the above technical solution is explained below: During use, as the sapling grows thicker and longer inside the protective clamp 2s, it gradually rises and pushes the inner rubber strip 2g, causing it to roll up in the same direction as the back of the protective clamp 2s. This causes the protective clamp 2s to press against the arc-shaped back of the protective clamp 2s, thus locking and stopping the process of the protective clamp 2s swinging in the direction of the sapling's growth. Therefore, an assistive body 2f is provided inside the cover 2. During the sapling's growth, it will wear against the rubber strip 2g, allowing the rubber strip 2g to roll outward along the swing rod 2f4, thus allowing the swing rod 2f4 to... 4. Gradually merging, it can pull the folded tube 2f2 to synchronously close into a circular structure, initially confining the rolled-up adhesive strip 2g, and the top of the swing rod 2f4 will drive the bottom of the arc frame f53 to push the roller f51 to roll inside the wrapping strip 2f1 through the support rod f55, so that it pushes the wrapping strip 2f1 to stretch and merge synchronously, and wrap the edge of the contact plate 54b. Then, it will push the contact plate 54b to rotate between the arc frames f53 through the insert bracket f52, effectively swinging the through rod 54m and the card plate 54v in conjunction with the strap 54n towards the arc frame f53. The central arch provides better outward support to the curved frame f53, helping the surrounding strip 2f1 to expand outward and rigidly resisting further curling of the rubber strip 2g in the middle. Simultaneously, as the folding tube 2f2 closes into a circular structure, the connecting rod f31 expands outward via the fixing seat f32. The swing handle f35 at the bottom of the connecting rod f31 swings and flattens outward along with the stretching of the surrounding strip 2f1, causing the opening and closing clamp f34 inside the swing handle f35 to open as the swing handle f35 opens, releasing the resistance to the sleeve frame 33z. The clamping mechanism allows the frame 33z to slide towards the center of gravity of the connecting rod f31 between the gripper 33v and the handle 33b. Then, through the force traction of the pressure block 33x and the arch 33c, the swing handle f35 can be tilted and overlapped to the outside of the seedling, and directionally moved into the protective clamp 2s. This allows the protective clamp 2s to be pried open and swing smoothly outward, making it more suitable for protecting seedlings during the cultivation period. It also achieves a highly efficient support and protection function during the cultivation period, ensuring the protective cover's protective effect on forestry seedling cultivation.
