Description
Technical Field
[0001] This invention relates to the field of sapling protection technology, specifically to a cold-resistant and frost-resistant protection device for saplings in densely planted Camellia oleifera afforestation. Background Technology
[0002] Camellia oleifera, an important woody oil crop in my country, is particularly vulnerable to damage during the dense planting and afforestation process. Young trees are especially susceptible to frost damage under harsh weather conditions such as low temperatures and cold waves in winter, which can lead to frost damage to branches and roots, and in severe cases, even plant death. This greatly affects the survival rate and subsequent yield of Camellia oleifera afforestation.
[0003] Currently, existing technologies for protecting young camellia trees from cold and frost mostly involve simple methods such as wrapping them with straw, plastic film, or installing single protective boards. However, these methods have several drawbacks: First, wrapping is cumbersome to operate and does not effectively secure the young trees, easily falling off under wind and failing to provide long-term stable protection. Second, traditional protective boards are mostly monolithic structures, inconvenient for transportation and installation, and cannot be flexibly adjusted according to the growth stage of the young trees (such as trunk thickness and height), resulting in poor versatility. Third, existing protective devices lack stability and are prone to tipping over in complex terrain or strong winds, making it difficult to effectively resist the impact of the external environment on young trees. Fourth, the fit between the protective device and the young tree is difficult to control; if it is too loose, it will not provide effective cold protection and insulation, while if it is too tight, it may restrict the growth of the young trees or even cause damage to the trunk.
[0004] To address these issues, the present invention provides a cold-resistant and frost-resistant protection device for young trees in densely planted Camellia oleifera afforestation. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a cold-resistant and frost-resistant protection device for young trees in densely planted Camellia oleifera afforestation, solving the problems mentioned in the background section.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a cold-resistant and frost-resistant protection device for young trees in densely planted Camellia oleifera afforestation, comprising a stable base, a support plate, and a protective baffle. The support plate is located inside the protective baffle. The protective baffle includes a first protective baffle and a second protective baffle. There are two stable bases and four support plates. There are two first protective baffles and two second protective baffles, which are spaced apart and interlocked. The protective baffle is detachably located on top of the stable base. A connecting frame is fixedly installed on the outside of the support plate. The connecting frame passes through the protective baffle and slides along its inner surface, allowing the support plate to move relative to the protective baffle to accommodate young trees of different thicknesses.
[0007] The bottom of the first protective baffle is fixedly provided with a first snap-fit block, and the bottom of the second protective baffle is fixedly provided with a second snap-fit block. The stabilizing base is provided with a first snap-fit groove and a second snap-fit groove. The outer surface of the first snap-fit block engages with the inner surface of the first snap-fit groove to achieve quick positioning and fixation of the first protective baffle and the stabilizing base. The second snap-fit block is slidably disposed inside the second snap-fit groove to provide space for the installation and adjustment of the second protective baffle.
[0008] Preferably, limit strips are fixedly provided on both sides of the second protective baffle, and limit grooves are provided on both sides of the first protective baffle. The outer surface of the limit strip is engaged with the inner surface of the limit groove. Through the cooperation of the limit strip and the limit groove, the connection stability of the first protective baffle and the second protective baffle after insertion is ensured, the relative displacement between the two is avoided, and the integrity of the outer protective structure is improved.
[0009] Preferably, an L-shaped connecting block is fixedly installed at the bottom edge of the second protective baffle, a sliding groove is provided at the top of the stabilizing base, an insert is fixedly installed on the first protective baffle near the bottom edge of the connecting block, and a slot is provided at the top of the stabilizing base. After inserting the connecting block into the sliding groove, rotating the second protective baffle causes the end of the connecting block to insert into the slot, and then inserting the insert, so that the insert is located in the slot, passes through the connecting block, and engages with its inner surface. Through the synergistic action of the L-shaped connecting block, sliding groove, slot, and insert, the second protective baffle and the stabilizing base are detachably fixed, and the connection structure is stable, preventing the protective baffle from falling off during use.
[0010] Preferably, the bottom of the stabilizing base is fixedly provided with several stabilizing piles. The stabilizing piles can be inserted into the soil to enhance the connection strength between the stabilizing base and the ground, improve the stability of the entire device in complex terrain and strong wind environments, and prevent the device from tipping over.
[0011] Preferably, a connecting spring is fixedly installed between the connecting frame and the outer wall of the protective baffle, and an adjustment component is installed on the protective baffle to move the connecting frame and thus adjust the position of the supporting protective plate. The spacing of the supporting protective plates can be flexibly changed by the adjustment component to accommodate saplings of different thicknesses, improving the versatility of the device.
[0012] Preferably, the adjusting assembly includes an adjusting protrusion fixedly mounted on the inner wall of the connecting frame, and a wedge-shaped block slidably mounted on the outer surface of the protective baffle, wherein the end of the adjusting protrusion abuts against the outer surface of the wedge-shaped block. By sliding the wedge-shaped block, the adjusting protrusion is compressed, thereby driving the connecting frame and the supporting guard plate to move, achieving precise adjustment of the position of the supporting guard plate. The adjustment method is simple and efficient.
[0013] Preferably, both the first and second protective baffles have arc-shaped grooves on their outer surfaces. Adjusting rods are slidably mounted inside these arc-shaped grooves, with the ends of two adjacent adjusting rods interlocked and locked in place by positioning bolts. The wedge blocks are fixedly mounted on the outer surfaces of the adjusting rods. By sliding the adjusting rods, the wedge blocks can be moved synchronously, enabling synchronized adjustment of multiple connecting frames and improving adjustment efficiency.
[0014] Preferably, a positioning rod is slidably disposed through one of the adjusting rods, and several positioning grooves are formed on the outer surface of the protective baffle. The end of the positioning rod is inserted into the positioning groove and engaged with its inner surface. By engaging the positioning rod with different positioning grooves, the position of the adjusting rod can be fixed, thereby locking the adjustment state of the support plate and ensuring the stable support of the support plate for the sapling.
[0015] Beneficial effects
[0016] This invention provides a cold-resistant and frost-resistant protection device for young trees in densely planted Camellia oleifera afforestation. Compared with the prior art, it has the following advantages:
[0017] (1) The cold and frost protection device for densely planted Camellia oleifera afforestation saplings has a stable protective structure and strong resistance: it adopts a combination design of "stable base + double-layer protective baffle + inner support plate". The conical stable pile at the bottom of the stable base can penetrate into the soil, which greatly improves the device's anti-tipping ability in complex terrains such as mountains and slopes and strong wind environments; the first protective baffle and the second protective baffle are connected by limiting strips and limiting grooves. The bottom is fixed to the stable base by means of snap-fit blocks, L-shaped connecting blocks and insert blocks. After splicing, a complete and solid outer protective barrier is formed, which can effectively resist low temperature invasion, wind impact and debris collision, and avoid direct damage to saplings from the external environment; the four inner support plates are evenly wrapped around the trunk. With the elastic force of the connecting spring, the trunk is supported in all directions, preventing the trunk from being blown down by the wind after freezing brittle due to low temperature. The double protective structure significantly improves the cold and frost resistance and impact resistance of saplings.
[0018] (2) The cold and frost protection device for densely planted Camellia oleifera saplings is flexible, convenient and versatile: the spacing between the support plates can be precisely adjusted by adjusting the components. The wedge block is slid by the adjusting rod, which squeezes the adjusting convex column and pushes the connecting frame and support plates to move. With the positioning rod and the multi-position positioning groove locking, it can be flexibly adapted to Camellia oleifera saplings of different thicknesses. At the same time, as the saplings grow, there is no need to replace the device. The spacing between the support plates can be adjusted again by loosening the positioning rod, which meets the protection needs of the saplings throughout their growth cycle. It effectively solves the problems of traditional protection devices being inflexible and having poor versatility, and reduces the cost of afforestation protection.
[0019] (3) The cold-resistant and frost-resistant protection device for young trees in densely planted Camellia oleifera afforestation is easy to install and disassemble and has strong practicality: each component of the device adopts a modular design, and the protective baffle and the stable base are connected by snap-fit, plug-in and rotation locking, etc., and can be assembled and disassembled without complicated tools; the disassembled components are small in size and light in weight, which is convenient for transportation and storage, and is especially suitable for batch operations in large-scale dense Camellia oleifera afforestation scenarios; at the same time, the detachable design allows the device to be stored in non-cold-resistant seasons (such as summer), reducing space occupation, extending the service life of the device, and improving the convenience and economy in practical applications.

Detailed Implementation
[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.
[0030] Please see Figures 1-8 This invention provides a technical solution: a cold-resistant and frost-resistant protection device for young trees in densely planted Camellia oleifera afforestation, comprising a stable base 1, a support plate 2, and a protective baffle 3. The support plate 2 is made of elastic rubber material, which is soft and has good toughness. It can fit tightly against the trunk of the young tree, avoiding physical damage such as scratching and squeezing caused by hard materials. It can also reduce heat loss from the trunk by utilizing the heat insulation properties of the material itself, providing basic heat insulation protection for the young tree. The protective baffle 3 is made of hard plastic or lightweight metal material. Its hardness allows it to resist the impact of external wind and collisions with debris, forming a solid outer protective barrier. At the same time, the selected material also has certain heat insulation properties, which can further block the invasion of low temperature on the young tree. The lightweight design facilitates manual operation during transportation, installation, and disassembly.
[0031] The support plate 2 is located inside the protective baffle 3, forming a dual protective structure of "inner layer support + outer layer protection and barrier" to protect the sapling from all angles. The protective baffle 3 includes protective baffle one 301 and protective baffle two 302. There are two stabilizing bases 1, which are symmetrically distributed. This symmetrical design can make the overall force of the device balanced, ensuring more stable protection for the sapling and facilitating quick positioning during installation. There are four support plates 2, which are evenly distributed around the sapling. The distribution of the four support plates can ensure that the sapling trunk receives uniform support and protection in all directions, avoiding excessive local stress that could cause trunk deformation and preventing blind spots in protection. Two protective baffles, 301 and 302, are provided, spaced apart. This spaced arrangement ensures the integrity of the outer protective layer while providing operational space for assembly and disassembly. The protective baffles 301 and 302 are interlocked, allowing for quick assembly without complex fixing structures, thus improving installation efficiency. The protective baffle 3 is detachably mounted on top of the stabilizing base 1, allowing the device to be disassembled and stored during off-seasons (such as summer), reducing space occupation and facilitating subsequent maintenance and parts replacement. A connecting frame 4 is fixedly mounted on the outer side of the supporting protective plate 2. The connecting frame 4 passes through the protective baffle 3 and slides along its inner surface. Serving as the connection medium between the supporting protective plate 2 and the protective baffle 3, the sliding feature of the connecting frame 4 provides a basis for adjusting the position of the supporting protective plate 2, allowing it to move flexibly according to the thickness of the sapling trunk.
[0032] A snap-fit block 5 is fixedly installed at the bottom of the first protective baffle 301, and a snap-fit block 6 is fixedly installed at the bottom of the second protective baffle 302. The stabilizing base 1 has a snap-fit groove 101 and a snap-fit groove 102. The outer surface of the snap-fit block 5 is engaged with the inner surface of the snap-fit groove 101. The snap-fit engagement method can quickly achieve the positioning and fixation of the first protective baffle 301 and the stabilizing base 1, and the connection is stable and not easy to loosen. The snap-fit block 6 is slidably installed inside the snap-fit groove 102.
[0033] Both sides of the second protective baffle 302 are fixedly equipped with limiting strips 7, and both sides of the first protective baffle 301 are provided with limiting grooves 8. The outer surface of the limiting strip 7 is engaged with the inner surface of the limiting groove 8. The engagement of the limiting strip 7 and the limiting groove 8 can limit the relative displacement of the first protective baffle 301 and the second protective baffle 302 in the horizontal direction, so that the two are spliced together to form a whole, enhancing the stability of the outer protective structure, avoiding gaps or misalignment under the action of external forces such as wind, and ensuring the protective effect.
[0034] An L-shaped connecting block 9 is fixedly installed at the bottom edge of the second protective baffle 302. A sliding groove 103 is provided on the top of the stable base 1. An insert block 10 is fixedly installed on the first protective baffle 301 near the bottom edge of the connecting block 9. A slot 104 is provided on the top of the stable base 1. During installation, the connecting block 9 is first inserted into the sliding groove 103, which provides guidance and space for the insertion and rotation of the connecting block 9. Then, the second protective baffle 302 is rotated, causing the end of the connecting block 9 to be inserted into the slot 104. After rotation, the L-shaped connecting block can form a snap-fit connection with the slot 104, initially fixing the position of the second protective baffle 302. Then, the insert block 10 is inserted into the slot 104, so that the insert block 10 passes through the connecting block 9 and engages with its inner surface. The setting of the insert block 10 further locks the position of the connecting block 9, preventing it from rotating or falling off during use. This achieves multiple stable connections between the second protective baffle 302 and the stable base 1, ensuring the reliability of the overall structure of the device.
[0035] The bottom of the stabilizing base 1 is fixed with several stabilizing piles 11. The stabilizing piles 11 have a conical structure. The conical design allows them to be easily inserted into the soil, increasing the contact depth and friction with the soil. This effectively improves the device's resistance to tipping in complex terrain (such as mountains and slopes) and strong wind environments, providing solid bottom support for the entire protective device and preventing it from losing its protective function for the saplings due to tipping over.
[0036] A connecting spring 12 is fixedly installed between the connecting frame 4 and the outer wall of the protective baffle 3. The connecting spring 12 is always in a stretched state, providing a continuous centripetal elastic force to the supporting baffle 2. This elastic force ensures that the supporting baffle 2 always fits tightly against the trunk of the sapling, ensuring heat preservation and support effects. At the same time, the elastic design has a buffering effect. When the sapling shakes slightly or is impacted by external forces, the connecting spring 12 can absorb part of the impact force through expansion and contraction, preventing the supporting baffle 2 from causing hard compression damage to the trunk. The protective baffle 3 is equipped with an adjustment component 13 that drives the connecting frame 4 to move, thereby adjusting the position of the supporting baffle 2. The adjustment component 13 provides a convenient way to adjust the spacing of the supporting baffle 2, allowing the device to adapt to saplings of different thicknesses.
[0037] The adjustment assembly 13 includes an adjustment protrusion 1301 fixedly mounted on the inner wall of the connecting frame 4, and a wedge block 1302 slidably mounted on the outer surface of the protective baffle 3. The end of the adjustment protrusion 1301 abuts against the outer surface of the wedge block 1302, and the inclined surface of the wedge block 1302 is adapted to the end of the adjustment protrusion 1301, so that the wedge block 1302 can squeeze the adjustment protrusion 1301 to move laterally when it slides. When the wedge block 1302 slides, its inclined surface will generate a lateral thrust on the adjustment protrusion 1301. Since the adjustment protrusion 1301 is fixedly connected to the connecting frame 4, the thrust will be transmitted to the connecting frame 4, thereby driving the support guard plate 2 to move synchronously, realizing precise adjustment of the position of the support guard plate 2.
[0038] Both protective baffle 1 (301) and protective baffle 2 (302) have arc-shaped grooves 1303 on their outer surfaces. An adjusting rod 1304 is slidably mounted inside the arc-shaped groove 1303. The arc-shaped design of the groove 1303 matches the arc-shaped structure of the protective baffle, ensuring smooth sliding of the adjusting rod 1304 and limiting its sliding direction. The ends of adjacent adjusting rods 1304 are interlocked and locked with positioning bolts 1305. This interlocking method allows for flexible adjustment of the splicing length of the adjusting rods 1304 according to the assembly length of the protective baffle 3, ensuring that the adjusting assembly 13 covers the entire outer circumference of the protective baffle. The positioning bolts 1305 lock the spliced adjusting rods 1304 in place, preventing sliding or separation. The wedge block 1302 is fixedly installed on the outer surface of the adjusting rod 1304, so that when the adjusting rod 1304 slides, it can drive the wedge block 1302 to move synchronously, realize the linkage adjustment of multiple wedge blocks 1302, and then drive multiple support plates 2 to move synchronously, ensuring that the fit between the support plate 2 and the trunk of the sapling is uniform.
[0039] A positioning rod 1306 is slidably mounted on one of the adjusting rods 1304. Several positioning grooves 1307 are formed on the outer surface of the protective baffle 3. The end of the positioning rod 1306 is inserted into the positioning groove 1307 and engaged with its inner surface. Through the cooperation of the positioning rod 1306 with different positioning grooves 1307, the position of the adjusting rod 1304 is fixed, thereby locking the spacing of the support plate 2. After the support plate 2 is adjusted to the appropriate position, the positioning rod 1306 is inserted into the corresponding positioning groove 1307 to fix the position of the adjusting rod 1304, thereby locking the state of the wedge block 1302 and the support plate 2. This prevents the adjusting rod 1304 from sliding due to external forces during use, ensuring stable support and protection of the sapling by the support plate 2. The multiple positioning grooves 1307 provide multiple fixed positions for the adjusting rod 1304, meeting the adjustment needs of saplings of different thicknesses and improving the versatility of the device.
[0040] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0041] During operation, firstly, two stabilizing bases 1 are symmetrically placed on both sides of the sapling and fixed to the ground by stabilizing stakes 11. Then, the snap-fit block 6 at the bottom of the second protective baffle 302 is inserted into the snap-fit groove 102 of the stabilizing base 1, while the connecting block 9 at the bottom of the second protective baffle 302 is inserted into the sliding groove 103. The second protective baffle 302 is rotated until the connecting block 9 is rotated into the slot 104. Next, the snap-fit block 5 at the bottom of the first protective baffle 301 is aligned with the snap-fit groove 101 of the stabilizing base 1. At the same time, the limiting groove 8 of the first protective baffle 301 is engaged with the outer surface of the limiting strips 7 on both sides of the second protective baffle 302. The first protective baffle 301 is pressed down until the snap-fit block 5 is engaged into the snap-fit groove 101, and the insert block 10 is inserted into the connecting block 9, thus achieving a stable connection between the first protective baffle 301 and the stabilizing base 1 and the second protective baffle 302. The first protective baffle 301 and the second protective baffle 302 are assembled to form a complete outer protective structure.
[0042] Then, adjust the spacing of the support plates 2 according to the thickness of the sapling. First, pull out the positioning rod 1306 to release the fixing of the adjusting rod 1304. Push the adjusting rod 1304 to slide along the arc groove 1303. The adjusting rod 1304 drives the wedge block 1302 to move. The wedge block 1302 presses the adjusting protrusion 1301 through the inclined surface, so that the adjusting protrusion 1301 drives the connecting frame 4 and the support plates 2 to move away from or closer to the sapling. When the support plates 2 fit the sapling trunk and the pressure is moderate, stop pushing the adjusting rod 1304. Insert the positioning rod 1306 into the corresponding positioning groove 1307 to fix the position of the adjusting rod 1304, thereby locking the state of the support plates 2 and ensuring that the support plates 2 fit the trunk tightly without causing excessive pressure on the trunk.
[0043] During use, the connecting spring 12 always provides elastic support for the support plate 2, maintaining the fit between the support plate 2 and the tree trunk, while buffering external impacts. The outer protective baffle 3 effectively resists low-temperature invasion and wind impact, reducing direct contact between cold air and the sapling. The inner support plate 2 further enhances the heat preservation effect and provides support for the tree trunk, preventing it from being broken by the wind after freezing. The two work together to achieve cold and frost protection for the sapling. When the sapling grows thicker, the spacing of the support plate 2 can be adjusted again by adjusting the component 13. Loosening the positioning rod 1306 and pushing the adjusting rod 1304 will move the support plate 2 outward to adapt to the growth needs of the sapling. There is no need to replace the entire device, extending the service life of the device.
