Description

Technical Field

[0001] This invention relates to the field of forest cultivation and water-saving irrigation technology, specifically to water-saving, drought-resistant, and rain-harvesting planting holes for forest cultivation projects and their usage methods. Background Technology

[0002] In current forest cultivation, water conservation and drought resistance in planting pits mainly rely on "artificial watering", "simple mulching to retain moisture" or "natural rainwater harvesting", lacking a dedicated integrated structure for rainwater harvesting and retention: artificial watering is costly and inefficient, and difficult to cover large-scale afforestation areas; simple mulching is easily damaged and cannot be adapted to tree growth.

[0003] Poor rainwater harvesting and low rainwater utilization: Without a directional rainwater harvesting structure, rainwater falls randomly into the planting hole, and some is lost along the surface, resulting in insufficient rainwater harvesting and utilization; lack of rainwater diversion design makes it impossible to accurately guide scattered rainwater into the core area of ​​the planting hole, resulting in limited water-saving effect; rapid water evaporation and weak moisture retention: The planting hole has no cover or a simple cover structure, and the soil surface is directly exposed to the air, resulting in a rapid rate of water evaporation, which is difficult to meet the growth needs of tree roots. Summary of the Invention

[0004] The purpose of this invention is to provide water-saving, drought-resistant, and rain-harvesting planting pits for forest cultivation projects and their usage methods, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water-saving, drought-resistant, and rain-harvesting planting hole for forest cultivation projects and its usage method, comprising a planting hole and a placement plate. The placement plates are symmetrically placed on both sides of the upper part of the planting hole. Two sets of first rotating grooves are formed on the inner side of the placement plate. A rotating shaft is rotatably connected inside the first rotating groove. A first rotating block is fixedly connected to the outer side of the rotating shaft. A torsion spring is fixedly connected between the first rotating block and the inner wall of the first rotating groove. The torsion spring is sleeved on the outer side of the rotating shaft. An outer shielding frame is fixedly connected to the outer side of the first rotating block. An inner shielding frame is slidably connected inside the outer shielding frame. Four sets of embedding grooves are formed at the lower part of the placement plate. An embedding plate is sleeved inside the embedding groove. An installation plate is fixedly connected to the lower part of the inner side of the embedding plate. An installation ring is fixedly connected to the lower part between two sets of installation plates. Two sets of second rotating grooves are formed inside the installation ring. A second rotating block is rotatably connected inside the second rotating groove. An intercepting plate is fixedly connected to the outer side of the second rotating block. The intercepting plate and the outer shielding frame are staggered.

[0006] Preferably, a connecting plate is fixedly connected to the inner middle of the inner shielding frame, and a guide rod is fixedly connected to the inner side of the outer shielding frame. The guide rod is slidably connected to the inside of the connecting plate, and a spring is fixedly connected between the connecting plate and the inner wall of the outer shielding frame. The spring is sleeved on the outside of the guide rod.

[0007] Preferably, a limiting piece is fixedly connected to the other end of the guide rod.

[0008] Preferably, two sets of rotating rods are fixedly connected to the inner sides of the inner shielding frame, and a shielding plate is rotatably connected to the outer side of the rotating rods. Positioning grooves are opened on both sides of the outer shielding frame, and a positioning plate is fixedly connected to one end of the shielding plate. The positioning plate is slidably connected to the inside of the positioning groove.

[0009] Preferably, the inner shield and the interceptor plate are fixedly connected to a mounting bracket, and the mounting bracket is rotatably connected to a roller.

[0010] Preferably, a guardrail is fixedly connected to the outer upper part of the interceptor plate.

[0011] Preferably, an upper limit frame is fixedly connected to the upper side of the placement plate, the upper limit frame is disposed on the upper part of the two sets of outer shielding frames, and a lower limit ring is fixedly connected to the lower part of the mounting ring, the lower limit ring is disposed on the lower part of the two sets of intercepting plates.

[0012] Preferably, the two sets of placement plates are fixedly connected to each other on both sides, and the placement plates have a number of mounting holes inside, while the embedding plate and the placement plates have mutually cooperating connecting holes inside.

[0013] A method for using water-saving, drought-resistant, and rain-harvesting planting holes in forest cultivation projects includes the following steps: S1: Equipment installation and fixing: First, dig planting holes in the afforestation area. Place the two placement plates on both sides symmetrically on the upper side of the planting hole through the installation holes. Then, insert the embedding plate into the embedding groove of the placement plate and fix it with bolts through the connecting holes. Rotate the second rotating block to make the interception plate have a slope structure with a high middle and low four sides. S2: Tree planting and adaptation adjustment: Plant the tree seedling in the center of the planting hole, ensuring that the trunk is inside the four sets of inner shielding frames and intercepting plates. The inner shielding frames are pressed tightly against the trunk under the action of springs, and the rollers are in contact with the surface of the trunk. S3: Rainwater harvesting and moisture retention: During rainfall, rainwater hits the surfaces of the outer and inner shielding frames, causing the torsion springs to deform and tilt the shielding frames downwards. Rainwater is then guided along the surface of the shielding frames into the planting holes. The intercepting plate intercepts the soil washed away by the rainwater, and the guardrail collects the loose surface soil. After the rainfall ends, the torsion springs reset and the shielding frames return to a horizontal position. The shielding frames and the shielding plates work together to cover the upper part of the planting holes, reducing soil moisture evaporation. S4: Tree growth adaptation: During the tree growth process, when the trunk thickens, the inner shielding frame extends and retracts outward along the guide rod under the elastic action of the spring, and the outer shielding frame and the intercepting plate naturally increase the tilt angle to adapt to the change in trunk diameter; S5: Equipment disassembly: When the equipment needs to be removed, first remove the bolts of the connecting plate, separate the two side placement plates, then remove the bolts of the connecting hole between the embedded plate and the placement plate, disconnect the equipment into upper and lower sections, and finally pull the outer shield outward to make the inner shield retract and detach from the tree trunk. Remove each component in turn to avoid damaging the tree.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves precise collection and diversion of rainwater through the synergistic action of an outer shielding frame, an inner shielding frame, and an interception plate: When rainwater hits the surfaces of the outer and inner shielding frames, the torsion springs deform under force, causing the shielding frames to tilt downwards, and the rainwater is smoothly diverted along the arc-shaped surface of the shielding frame into the planting hole, preventing rainwater from flowing away randomly along the ground surface; the inner shielding frame can extend and retract inward along the guide rod of the outer shielding frame, which not only does not obstruct the flow of rainwater due to structural fixation, but also ensures that the diversion path is always aligned with the core area of ​​the planting hole, significantly improving the utilization rate of limited rainwater in arid areas and reducing reliance on artificial watering; 2. This invention utilizes a multi-layered shielding structure to form a complete moisture-retaining system. The outer and inner shielding frames cover the upper part of the planting hole. After rainfall, the torsion spring resets, causing the shielding frames to return to a horizontal position, continuously shielding the soil surface of the planting hole and preventing the soil from being directly exposed to the air. The shielding plate can rotate synchronously with the shielding frame as it tilts, and the positioning plate is embedded in the positioning groove of the outer shielding frame, precisely blocking the gaps on both sides of the shielding frame and preventing external airflow from directly contacting the soil surface. This all-round shielding design can effectively slow down the rate of soil moisture evaporation, prolong the moist time of the soil in the planting hole, and provide a continuous water supply for the tree roots, making it particularly suitable for cultivation scenarios in arid regions where water resources are scarce.

[0015] 3. This invention features adjustable components that adapt to tree growth: The inner shielding frame's inner spring normally pushes it against the trunk; as the trunk thickens, the inner shielding frame extends outward along the guide rod, adapting to changes in trunk diameter through spring elastic deformation, maintaining a sealing effect without compressing the trunk; the rollers on the inner shielding frame and interceptor plate are in contact with the trunk surface, rolling along the trunk as the tree grows taller, significantly reducing friction between the tree and the equipment, ensuring smooth longitudinal growth; the upper limit frame and lower limit ring limit excessive tilting of the outer shielding frame and interceptor plate, respectively. As the tree crown expands, the shielding frame and interceptor plate naturally adjust their tilt angle, always adapting to the tree's growth state, with no structural constraints from seedling cultivation to mature tree growth. 4. This invention features a segmented, modular design for easy installation, adjustment, and removal: the two placement plates are detachably connected by connecting plates; removing the connecting plate bolts allows the two placement plates to be separated, preventing damage to the trees; the embedding plate is inserted into the embedding slot of the placement plate and fixed by connecting hole bolts; removing the bolts allows the equipment to be disassembled into upper and lower sections, facilitating adjustment of the equipment position or complete removal based on tree growth height; maintenance only requires cleaning fallen leaves and soil from the shielding frame and intercepting plate surface, checking the elasticity of the torsion springs and springs, and the rotation status of the rollers, requiring no complex tools, thus adapting to the standardized installation and post-maintenance needs of large-scale afforestation scenarios.

[0018] 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.

[0019] Please see Figure 1-5This invention provides a technical solution: a water-saving, drought-resistant, and rain-collecting planting pit for forest cultivation projects, comprising a planting pit 1 and a placement plate 2. The placement plates 2 are symmetrically placed on the upper sides of the planting pit 1. Two sets of first rotating grooves 3 are formed on the inner side of the placement plates 2. A rotating shaft 15 is rotatably connected inside the first rotating groove 3 via a deep groove ball bearing. A first rotating block 4 is fixedly connected to the outer side of the rotating shaft 15 by welding. A torsion spring 16 is fixedly connected between the first rotating block 4 and the inner wall of the first rotating groove 3 by spot welding. The torsion spring 16 is sleeved on the outer side of the rotating shaft 15, keeping the outer shielding frame 5 horizontal under normal conditions. After rain, it can tilt downwards to collect rainwater. The outer shielding frame 5 is fixedly connected to the outer side of the first rotating block 4 by welding. The outer shielding frame 5 is internally connected by a clearance fit. The device has an inner shielding frame 6 that can extend and retract inward along the outer shielding frame 5 to accommodate tree growth. The lower part of the placement plate 2 has four sets of embedding grooves 19. An embedding plate 20 is fitted inside the embedding groove 19 with a gap fit. An installation plate 21 is fixedly connected to the lower part of the inner side of the embedding plate 20 by welding. An installation ring 22 is fixedly connected to the lower part of the two sets of installation plates 21 by welding. The installation ring 22 has two sets of second rotating grooves 23. A second rotating block 24 is rotatably connected inside the second rotating groove 23 by a deep groove ball bearing. An interception plate 25 is fixedly connected to the outer side of the second rotating block 24 by welding. The interception plate 25 has a sloping structure that is high in the middle and low on all four sides to prevent soil erosion. The interception plate 25 and the outer shielding frame 5 are staggered to form a rainwater collection and interception synergistic structure. A connecting plate 9 is fixedly connected to the inner middle of the inner shielding frame 6 by welding. A guide rod 10 is fixedly connected to the inner side of the outer shielding frame 5 by welding. The guide rod 10 is slidably connected to the inside of the connecting plate 9 by clearance fit. A spring 11 is fixedly connected between the connecting plate 9 and the inner wall of the outer shielding frame 5 by spot welding. The spring 11 is sleeved on the outside of the guide rod 10. Under normal conditions, it pushes the inner shielding frame 6 to stick tightly to the tree to ensure the shielding and sealing effect, and at the same time adapts to the thickening of the tree trunk. The other end of the guide rod 10 is fixedly connected to the limiting piece 12 by welding. The limiting piece 12 prevents the connecting plate 9 from detaching from the guide rod 10, ensuring the stability of the inner shielding frame 6 during the extension and retraction process and preventing it from falling off. The inner shielding frame 6 has two sets of rotating rods 7 fixedly connected to its inner sides by welding. The outer side of the rotating rods 7 is rotatably connected to the shielding plate 8 by a deep groove ball bearing. The outer shielding frame 5 has positioning grooves 13 on both sides. One end of the shielding plate 8 is fixedly connected to the positioning plate 14 by welding. The positioning plate 14 is slidably connected to the positioning groove 13 by clearance fit. The shielding plate 8 can rotate synchronously with the shielding frame as it tilts, blocking the gaps on both sides and reducing water evaporation and rainwater loss. An installation frame 17 is fixedly connected to the inner side of the inner shielding frame 6 and the intercepting plate 25 by welding. Inside the installation frame 17, a roller 18 is rotatably connected by a deep groove ball bearing. The roller 18 fits in close contact with the tree trunk, reducing the frictional resistance between the tree and the shielding frame and the intercepting plate 25 during tree growth, ensuring smooth growth of the tree, and at the same time not affecting the adjustment of the tilt angle of the shielding frame. A guardrail 26 is fixedly connected to the upper outer side of the interception plate 25 by welding. The guardrail 26 is set around the interception plate 25 to facilitate the collection of surface loose soil washed by rainwater, prevent soil loss, and store a small amount of loose soil to protect the tree root system. An upper limit frame 28 is fixedly connected to the upper side of the placement plate 2 by welding. The upper limit frame 28 is set on the upper part of the two sets of outer shielding frames 5, which restricts the outer shielding frames 5 from tilting upward. A lower limit ring 27 is fixedly connected to the lower part of the mounting ring 22 by welding. The lower limit ring 27 is set on the lower part of the two sets of intercepting plates 25, which restricts the intercepting plates 25 from tilting downward. Two sets of placement plates 2 are detachably connected to each other on opposite sides by bolts with connecting plates 29. The connecting plates 29 are used to fix the two side placement plates 2. After disassembly, the two side structures can be separated. The placement plates 2 have several sets of mounting holes 30 inside, which are fixed to the ground by expansion bolts to ensure structural stability. The embedded plate 20 and the placement plates 2 have mutually matching connecting holes 31 inside, which are fixed by bolts. After disassembly, the equipment can be separated into upper and lower sections for easy removal. A method for using water-saving, drought-resistant, and rain-harvesting planting holes in forest cultivation projects includes the following steps: S1: Equipment installation and fixing: First, dig planting holes 1 in the afforestation area, place the two side placement plates 2 symmetrically on the upper two sides of the planting hole 1, and insert expansion bolts through the mounting holes 30 to fix the placement plates 2 to the ground; then insert the embedding plate 20 into the embedding groove 19 of the placement plate 2, and fix it with bolts through the connecting holes 31. Unfold the outer shielding frame 5 and the inner shielding frame 6. The torsion spring 16 drives the outer shielding frame 5 to keep it horizontal. Adjust the shielding plate 8 so that the positioning plate 14 is embedded in the positioning groove 13 to block the gap on both sides; rotate the second rotating block 24 so that the intercepting plate 25 has a slope structure of "high in the middle and low on all four sides", and the lower limit ring 27 restricts its lowest tilt position; S2: Tree planting and adaptation adjustment: Plant the tree seedling in the center of the planting hole 1, ensuring that the trunk is inside the four sets of inner shielding frames 6 and intercepting plates 25; the inner shielding frame 6 is pressed tightly against the trunk under the action of spring 11, and the roller 18 is in contact with the surface of the trunk; according to the thickness of the trunk, the inner shielding frame 6 extends and retracts along the guide rod 10 of the outer shielding frame 5 to adjust the fit, so as to ensure the sealing without squeezing the trunk; S3: Rainwater harvesting and moisture retention: During rainfall, rainwater hits the surfaces of the outer shielding frame 5 and the inner shielding frame 6, causing the torsion spring 16 to deform under stress, tilting the shielding frame downwards. Rainwater is then guided along the surface of the shielding frame into the planting hole 1. The slope structure of the interception plate 25 guides the rainwater to converge and intercepts the soil washed away by the rainwater. The guardrail 26 collects the loose surface soil. After the rainfall ends, the torsion spring 16 resets, causing the shielding frame to return to a horizontal position. The shielding frame and the shielding plate 8 work together to cover the upper part of the planting hole 1, reducing soil moisture evaporation. S4: Tree growth adaptation: During tree growth, as the trunk thickens, the inner shielding frame 6 extends and retracts outward along the guide rod 10 under the elastic action of the spring 11 to adapt to changes in trunk diameter; as the tree grows taller, the roller 18 rolls along the trunk surface to reduce frictional resistance; as the tree crown expands, the outer shielding frame 5 and the intercepting plate 25 naturally increase their tilt angle, while the upper limit frame 28 and the lower limit ring 27 limit excessive tilting to avoid structural damage; S5: Equipment disassembly: Regularly clean the soil and fallen leaves from the surfaces of the outer shield 5, inner shield 6, and interceptor plate 25, and check the elasticity of the torsion spring 16 and spring 11 and the smoothness of the rotation of the roller 18; when the equipment needs to be removed, first remove the bolts of the connecting piece 29 and separate the two side placement plates 2; then remove the bolts of the connecting hole 31 between the embedded plate 20 and the placement plate 2, and disconnect the equipment in sections; finally, pull the outer shield 5 outward to retract the inner shield 6 and detach it from the tree trunk, and remove each component in turn to avoid damaging the tree.

[0020] Working principle: When using this invention: dig planting pit 1 in the afforestation area according to the preset specifications, level the ground surface above the planting pit 1, place the two placement plates 2 symmetrically on the upper sides of the planting pit 1, insert expansion bolts through the mounting holes 30 to fix the placement plates 2 to the ground and ensure horizontal stability; insert the embedding plate 20 into the embedding groove 19 of the placement plate 2, and fix it with bolts through the connecting holes 31, so that the mounting plate 21 and the mounting ring 22 are directly above the planting pit 1; Unfold the outer shield 5 and the inner shield 6, and use the torsion spring 16 to keep the outer shield 5 horizontal; adjust the shield 8 so that the positioning plate 14 is embedded in the positioning groove 13 to block the gap on both sides; rotate the second rotating block 24 so that the intercepting plate 25 has a sloping structure with a high middle and low four sides, and the lower limit ring 27 restricts its lowest tilt position; install the guardrail 26 to ensure that it surrounds the upper part of the intercepting plate 25. The sapling is planted in the center of the planting hole 1, ensuring that the trunk is inside the four sets of inner shielding frames 6 and intercepting plates 25; the inner shielding frame 6 is pressed tightly against the trunk under the action of spring 11, and the roller 18 is in contact with the surface of the trunk; according to the thickness of the trunk, the inner shielding frame 6 extends and retracts along the guide rod 10 of the outer shielding frame 5 to adjust the fit, so as to ensure both the sealing and the trunk is not squeezed. During rainfall, rainwater strikes the surfaces of the outer shielding frame 5 and the inner shielding frame 6, causing the torsion spring 16 to deform under stress, tilting the shielding frame downwards. Rainwater is then guided along the surface of the shielding frame into the planting hole 1. The intercepting plate 25 intercepts the soil washed away by the rainwater, and the guardrail 26 collects the loose surface soil to prevent soil loss. After the rainfall ends, the torsion spring 16 returns to its original position, causing the shielding frame to return to a horizontal position. The shielding frame and the shielding plate 8 work together to cover the upper part of the planting hole 1, reducing soil moisture evaporation and prolonging the moist time. During the tree's growth, as the trunk thickens, the inner shielding frame 6 extends and retracts outward along the guide rod 10 under the elastic action of the spring 11 to adapt to changes in the trunk diameter; the intercepting plate 25 adjusts its tilt angle synchronously with the tree's growth, always maintaining a soil collection structure that is high in the middle and low on all four sides, without affecting the development of the tree's root system. When the equipment needs to be removed, first remove the bolts of the connecting piece 29 and separate the two side placement plates 2; remove the bolts of the connecting hole 31 between the embedded plate 20 and the placement plate 2, separate the equipment into upper and lower sections, pull the outer shield 5 outward, the inner shield 6 retracts and detaches from the tree trunk, and remove each component in turn to avoid damaging the tree.
