Description

Technical Field

[0001] The present invention relates to the technical field of garden planting, and particularly relates to an assembled seedling support device. Background Art

[0002] With the continuous advancement of cities and the increasing improvement of urban living quality, the refined construction of road greening and pocket parks has received more and more attention. At present, in newly built and renovated greening projects, not only the greening landscape effect during the day is pursued, but also the night lighting and beautification functions are emphasized. However, traditional seedling support devices still generally use building materials such as Chinese fir poles and steel pipes and the method of earth heap cofferdams for support and fixation. Its main function is to help trees resist external forces such as wind before the roots are fully rooted and stable through external rigid support. Currently, the more common forms include triangular support, quadrilateral support, etc. By fixing one end of the support pole at an appropriate height of the tree trunk and inserting the other end obliquely into the ground, a stable support system is formed. At the same time, to enhance the support effect and facilitate watering, soil is usually piled up at the base of the tree trunk to form a cofferdam, which is both auxiliary for fixation and convenient for irrigation and water storage.

[0003] However, the existing support devices have obvious technical defects. The traditional Chinese fir pole support system has problems such as poor material durability and low repeated utilization rate. The steel pipe support faces the problems of heavy weight, inconvenient transportation and installation. Moreover, the traditional fixing method mostly uses wire direct bundling, which not only easily damages the bark to form a pathogen invasion channel, but also cannot adapt to the diameter change caused by the growth of the tree trunk. The simple integrated support structure is difficult to disassemble and assemble and cannot be reused. In addition, the existing support devices only consider structural requirements, mostly lack landscape adaptability, and ignore the coordination with the urban landscape lighting project. Such a support structure not only appears rough and simple during the day, but also affects the night view effect, and directly affects the quality and efficiency of urban greening construction.

[0004] Based on this, it is necessary to research an assembled seedling support device that is easy to assemble, beautiful and delicate, and can adapt to different tree trunk diameters to ensure the healthy growth of seedlings. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an assembled seedling support device, which effectively solves the problems existing in the existing support devices, such as inability to achieve standardized construction, inability to meet the requirements of lighting and beauty, low construction efficiency, poor resource utilization rate, and inconvenient construction.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: an assembled seedling support device, including a positioning piece, a support rod and a ring sleeve, at least two groups of positioning pieces are buckled together to form a positioning sleeve, and a accommodating space is formed in the middle of the positioning sleeve; multiple groups of support rods are distributed on the outside of the positioning sleeve, the top of each group of support rods is hinged to the outer end of the positioning sleeve, the lower part of the support rod extends obliquely outward, and the bottom is hinged with a vertical rod; the ring sleeve is arranged below the positioning sleeve and is coaxial with it; the top of the ring sleeve is provided with an installation groove and a card slot along the circumference, and a sub-buckle is adapted to be mounted in the card slot, and the sub-buckle is used to connect with the protective layer to protect the roots of the seedlings.

[0007] Furthermore, it also includes a irrigation assembly, which includes a water tank, an irrigation pipe, an outer sleeve and a irrigation head; the water tank is fixed on the outer side wall of the ring sleeve, and the ring sleeve is provided with an overflow channel connected to the water tank; the outer sleeve is evenly fixed to the bottom of the water tank along the circumference, the irrigation pipes are sleeved in the outer sleeve at intervals, a top spring is fixed between the bottom of the irrigation pipe and the outer sleeve, irrigation heads are evenly arranged on the side walls of the irrigation pipes, and the outer sleeve is provided with overflow holes corresponding to the irrigation heads, and the top of the irrigation pipe extends upward into the water tank; a plug rod is slidably sleeved in the irrigation pipe, and the top of the plug rod extends upward to the outside of the water tank, and a water inlet hole is opened on the side wall of the irrigation pipe, and the water inlet hole is connected to the water tank, and the plug rod can be slid up and down to block or open the water inlet hole.

[0008] Furthermore, drainage holes are vertically spaced apart on the side walls of the irrigation pipe, and the outer sleeve is provided with seepage holes corresponding to the positions of the drainage holes. A drainage pipe is sealed and installed in the drainage hole, and a irrigation head is slidably connected to the drainage pipe, and the side of the irrigation head adjacent to the outer sleeve is in an arc-shaped structure; and a micro spring is mounted on the drainage pipe between the irrigation head and the irrigation pipe, and an arc-shaped holder adapted to the irrigation head is fixed on the inner wall of the seepage hole of the outer sleeve, and when the irrigation head is adapted to correspond to the groove on the arc-shaped holder, the water flow in the irrigation pipe can synchronously seep out from the seepage hole through the arc-shaped nozzles of different heights.

[0009] Furthermore, a top plate is provided on the top of the insertion rod extending out of the outer sleeve, and an auxiliary spring is sleeved on the insertion rod between the top plate and the water tank. A locking assembly is provided on the top of the water tank for locking, limiting or releasing the top plate.

[0010] Furthermore, the locking assembly includes a rotating shaft and a pressure plate, the rotating shaft is rotatably installed on the top wall of the water tank, and the pressure plate is fixed on the rotating shaft by a locking sleeve. When the insertion rod drives the pressure plate to move downward until the auxiliary spring is compressed to the top surface of the water tank, the pressure plate is moved above the top plate of the insertion rod to limit the top plate.

[0011] Further, the loop sleeve includes two sets of arc-shaped bases. One end of each of the two sets of bases is provided with a jack, and the other end is provided with a plug adapted thereto. The plugs on the two sets of arc-shaped bases are adaptively inserted into the jacks to jointly form a loop sleeve with a circular structure.

[0012] Further, a rubber pad adapted to its shape is provided on the inner wall of the positioning member; the installation groove is used to place the lighting fixture; the protective layer is a sunscreen net or a PE film, and the sub-button is connected to the sunscreen net or the PU film to protect the roots of the seedlings from sun exposure or keep them warm.

[0014] Further, a hinge seat is provided at the top of the vertical rod to be hinged to the end of the support rod, and the bottom of the vertical rod is in a conical structure.

[0015] The beneficial effects of the above technical solutions are as follows: For the assembled seedling support device provided by the present invention, all components can be standardized for production, reducing on-site processing. The present invention uses positioning members such as Ω-shaped ones to be combined by buckling, forms a positioning sleeve through the fixation of screws and nuts, and is internally provided with a rubber pad adapted to the shape of the tree trunk. The rubber pad is fixed by screws to buffer the clamping force, avoiding rigid friction from damaging the tree trunk epidermis, reducing the risk of restricted growth of seedlings. At the same time, the size adjustment of the buckling combination enables it to adapt to tree trunks of different diameters, improving the construction efficiency, and providing an adjustable clamping force in cooperation with the locking of screws and nuts to adapt to the growth changes of seedlings.

[0016] In the present invention, the number of segmented support rods is adjustable to match the height of the seedlings, and each inclined support rod and the vertical rod form a triangular support, and the universal sleeve enhances the lateral stability, significantly improving the wind resistance. The lamp holder is embedded with a lighting fixture to realize the integration of landscape lighting and support. In addition, the loop sleeve integrates a cofferdam structure, and the irrigation assembly realizes layered synchronous irrigation through a water storage tank, a liftable irrigation pipe and water seepage holes. The cofferdam stores water and the layered water seepage are carried out simultaneously, ensuring uniform settlement of the soil, avoiding uneven layered compaction, and the overflow water is temporarily stored in the water storage tank for recycling to reduce water resource waste. The C-shaped card slot quickly connects the sunscreen or heat preservation layer to adapt to different environmental requirements.

[0017] In the present invention, the irrigation pipe is internally provided with a linkage structure of a top spring and a plug rod. The opening and closing of the water inlet hole are controlled by the lifting of the plug rod. The irrigation head cooperates with the arc-shaped clamping seat to realize the automatic on-off of the water seepage hole. The plug rod blocks or opens to control the water flow, avoiding root rot caused by over-irrigation. The multi-stage water seepage holes inject water into the soil at different depths synchronously, improving the root absorption efficiency. Through systematic design, the present invention breaks through the single-function limitation of traditional seedling support, realizes the technical upgrade from "passive fixation" to "active maintenance", significantly improves the seedling survival rate and the urban greening quality, reduces resource consumption, and meets the green construction standards.

Specific embodiments

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments: Embodiment 1. This embodiment aims to provide an assembled seedling support device, which is mainly used for supporting newly transplanted seedlings. In the prior art, simple materials such as Chinese fir poles and steel pipes are generally used for support and fixation, which are difficult to standardize, have low construction efficiency, and cannot meet the requirements of lighting and aesthetics. The assembled seedling support device provided in this embodiment is manufactured by the factory to form each part, and assembled and constructed on site, so as to achieve the effects of rapid and efficient, green and environmental protection, durable and beautiful, etc.

[0021] As Figures 1-5 shown, the assembled seedling support device provided in this embodiment includes a positioning member 11, a support rod 3 and a ring sleeve 2. At least two groups of positioning members 11 are combined by buckling to jointly form a positioning sleeve 1, and an accommodating space 15 is formed in the middle of the positioning sleeve 1. In the specific structure, as Figure 2As shown, in this embodiment, the positioning member 11 has an Ω-shaped structure. The front and rear sections form connecting ears, and screw holes are provided on the connecting ears. The screw holes of the two groups of positioning members 11 correspond to each other, and a screw rod 12 is threadedly connected in the screw holes. A nut is screwed on the screw rod 12, so as to combine the positioning members 11 together to form a positioning sleeve 1. The positioning sleeve 1 is fixedly sleeved on the trunk of the nursery stock. Further, mounting holes 13 are evenly formed in the positioning member 11, and rubber pads 16 adapted to its shape are provided on the inner walls of adjacent positioning members 11. Screws are screwed into the mounting holes 13 to fix the rubber pads 16. Thus, the rubber pads 16 are in contact with the trunk, avoiding that the rigid positioning sleeve structure directly clamps on the trunk and easily forms wounds, which affects the growth of the nursery stock.

[0022] As Figure 1 and 3 shown, multiple groups of support rods 3 are distributed on the outer side of the positioning sleeve 1. The tops of each group of support rods 3 are hinged to the outer end of the positioning sleeve. The lower part of the support rod 3 extends outward obliquely, and a vertical rod is hinged to its bottom; in a specific structure, the support rod 3 includes a rotating sleeve 31, a support rod 32, a connecting sleeve 34, a universal sleeve 35, etc. Among them, the upper part of the rotating sleeve 31 is a flattened structure. A connecting plate 14 is threadedly connected to the screw rod 12 of the positioning sleeve 1. The lower part of the connecting plate 14 extends outward obliquely (the inclination angle of the connecting plate 14 can be adaptively adjusted according to the actual diameter of the transplanted nursery stock and the installation position of the support during production). The lower part of the connecting plate 14 is hinged to the top of the rotating sleeve 31, so as to adjust the support position of the support rod 3.

[0023] Threads are cut on the inner wall of the rotating sleeve 31, and threads are also cut on the outer walls of the upper and lower ends of the support rod 32, so that the support rod 32 is threadedly connected to the rotating sleeve 31. Multiple groups of support rods 32 are butt-jointed end to end and are screwed and fixed by the connecting sleeve 34. During actual application, different numbers of support rods 32 are adaptively selected according to the height of the sapling, and their upper and lower ends are correspondingly connected together. The end of the lowermost support rod 32 is provided with a hinge seat to be hinged to the vertical rod. The vertical rod is used to be buried below the ground as the foundation of the overall support device. In addition, a U-shaped lamp holder 33 is fixed on the side wall of each support rod 32, and the inner cavities of the lamp holders 33 communicate correspondingly for installing lighting fixtures.

[0024] A reinforcing rod is also provided horizontally between the left and right adjacent support rods 3. The reinforcing rod is also composed of multiple support rods 32 butt-jointed together. The end of the reinforcing rod is connected to the main support rod 3 through a universal sleeve 35. Specifically, as Figure 4As shown in the figure, in this embodiment, the universal joint sleeve 35 includes a main shaft tube 351. A partition ring 356 is fixedly sleeved in the middle of the main shaft tube 351. Sleeve tubes 352 are respectively rotatably sleeved on the main shaft tube 351 on the upper and lower sides of the partition ring 356. Connecting blocks 353 are fixed on the side walls of the sleeve tubes 352. Universal joints 354 are fixedly connected to the outsides of the connecting blocks 353. Docking tubes 355 are fixed to the outsides of the universal joints 354. Threads adapted to the ends of the support rods 32 are machined on the inner walls of the docking tubes 355 for threaded connection with the support rods 32.

[0025] As Figure 1 and 5 As shown in the figure, the ring sleeve 2 is arranged below the positioning sleeve 1 and is coaxial with it. The ring sleeve 2 is used to wrap around the position near the root of the seedling above the ground to form a cofferdam structure, which is convenient for watering the seedling and connecting with the protective layer to protect the root of the seedling. Further, in this embodiment, mounting grooves 21 and C-shaped clamping grooves 22 are spaced apart along the circumference at the top of the ring sleeve 2. The mounting grooves 21 are used to place lighting fixtures. Sub-buttons are fitted and clamped in the C-shaped clamping grooves 22. The sub-buttons are used to connect with an external protective layer. The protective layer can be a sunscreen net or a PU film. One end is fixedly connected to the sub-button, and the other end is tied together by a self-adhesive binding band and sleeved above the root of the seedling to protect the root of the seedling from sunburn or keep it warm (the connection between the C-shaped sub-button and the protective layer is prior art and will not be elaborated here).

[0026] Principle description: For the assembled seedling support device provided in this embodiment, in actual application, two groups of positioning parts are buckled on the tree trunk, aligning the screw holes of the connecting ears, inserting the screw rod and fastening it with a nut to form an adjustable positioning sleeve. A rubber pad is installed on the inner wall of the positioning sleeve and fixed by screws to avoid damaging the tree bark with a rigid structure. Select an appropriate number of support rods according to the height of the seedling, and connect them through the connecting sleeve by threads to form a main support rod structure. Connect the top of the support rod to the positioning sleeve through a hinge structure and the bottom to the vertical rod through a hinge seat. After adjusting the support angle, bury the vertical rod and fix it. Install a strengthening rod between adjacent support rods and connect them through a universal joint sleeve to enhance the overall stability. Install a ring sleeve at the base of the tree trunk to form a cofferdam structure for convenient irrigation and water storage. Snap a sub-button into the C-shaped clamping groove of the ring sleeve, connect a sunscreen net or a heat preservation film, and cover the root area of the seedling to protect the root of the seedling. If it is during the sunny period in summer, connect one end of the sunshade net to the sub-button and connect the other three ends with self-adhesive binding bands in turn to achieve the effect of shading in summer and reducing water evaporation from the roots. In winter, replace the sunshade net with a PE film to achieve the effect of keeping the roots of the seedlings warm in winter. Finally, install an LED light strip or a small string of colored lights in the U-shaped lamp holder of the support rod to achieve the night lighting effect. At the same time, it is convenient to reasonably match the colors of the assembled seedling support, the cofferdam and the surrounding environment. Different colors can be sprayed on the surface of the support device. During subsequent maintenance, as the seedling grows, adjust the nut on the positioning sleeve in time according to the growth rate to achieve the effect of quickly loosening the binding on the seedling.

[0027] The prefabricated seedling support device provided by this embodiment adopts factory prefabricated components, which can be quickly assembled on site, reducing the dependence on labor, being easy to operate, enabling standardized construction, thus greatly reducing costs and improving construction efficiency, meeting the requirements of green construction and carbon emission construction. The modular design enables the components to be reused, reducing material waste and meeting the requirements of green construction.

[0028] Embodiment 2: On the basis of Embodiment 1, the same parts between this embodiment and Embodiment 1 will not be elaborated. The difference lies in that the prefabricated seedling support device provided by this embodiment further includes an irrigation assembly 4. After the seedlings are transplanted, it is necessary to water the seedlings every day in the early stage. In the prior art, the irrigation of seedlings is directly carried out into the cofferdam structure formed by the soil pile. The water penetrates into the roots of the seedlings through the soil. However, since the soil will settle to some extent during the slow downward penetration of the water, the amount of soil in contact with water above is more than that below, resulting in a larger settlement amount of the soil above than that below. This will cause the soil to be stratified due to uneven settlement, making the soil compaction uneven, thus affecting the growth of the seedlings. Therefore, the irrigation assembly 4 provided by this embodiment can not only simultaneously carry out synchronous irrigation operations on the soil at different depths underground, but also store the excess water in the cofferdam. Thus, the water can be simultaneously poured into the soil at different depths, maximizing the guarantee of uniform soil settlement and the irrigation uniformity of the soil at different depths, making the soil more compacted, and greatly improving the survival rate and growth quality of the seedlings.

[0029] As Figure 5 and 6 shown, in this embodiment, the irrigation assembly 4 includes a water storage tank 41, an irrigation pipe 43, an outer sleeve 42, an irrigation head 46, etc. The water storage tank 41 is fixed on the outer side wall of the collar 2. An overflow channel 23 communicating with the water storage tank 41 is opened on the collar 2. The excess water in the collar 2 can flow into the water storage tank 41 through the overflow channel 23 for temporary storage. As Figure 6 shown, the outer sleeve 42 is uniformly fixed at the bottom of the water storage tank 41 along the circumference. The irrigation pipe 43 is sleeved in the outer sleeve 42 at intervals. A top spring 47 is fixed between the bottom of the irrigation pipe 43 and the outer sleeve 42. Specifically, a telescopic rod is provided at the bottom of the irrigation pipe 43, and the top spring 47 is sleeved outside the telescopic rod. The upper and lower ends of the top spring 47 are respectively fixed to the irrigation pipe 43 and the outer sleeve 42.

[0030] A plug rod 48 is slidably sleeved inside the irrigation pipe 43. The top of the plug rod 48 extends upward outside the water storage tank 41, and there is a sealed connection between the plug rod 48 and the water storage tank 41. The top of the irrigation pipe 43 extends upward into the water storage tank 41, and a water inlet hole 49 is formed in the side wall of the irrigation pipe 43. The water inlet hole 49 communicates with the water storage tank 41. Sliding the plug rod 48 up and down can block or open the water inlet hole 49 with the plug rod 48. Further, in this embodiment, the plug rod 48 is a solid structure. A top plate 481 is fixed to the top of the plug rod 48. An auxiliary spring 482 is provided between the top plate 481 and the water storage tank 41. Under the action of the auxiliary spring 482, the plug rod 48 can move upward, so that the water inlet hole 49 on the irrigation pipe 43 is opened, and the water in the water storage tank 41 flows into the irrigation pipe 43 through the water inlet hole 49 and flows out through the irrigation head 46 on the side wall of the irrigation pipe. Press the top plate 481 downward to compress the auxiliary spring 482, and the plug rod 48 moves downward, so that the water inlet hole 49 can be blocked, and then under the action of the locking assembly 5 on the top of the water storage tank 41, the plug rod 48 can be restricted in this position.

[0031] With such a setting, when it is necessary to water the seedlings, the locking assembly 5 is opened. Under the action of the auxiliary spring 482, the plug rod 48 resets upward, and the water inlet hole 49 is opened to realize the water flow path. After watering, the top plate 481 is pressed tightly on the top of the water storage tank 41 by using the locking assembly 5, so as to block the water inlet hole 49. When the water level in the irrigation pipe 43 drops below the warning line, under the action of the top spring 47 at the bottom of the irrigation pipe 43, the irrigation pipe 43 and the irrigation head on its side wall move upward and reset, and the irrigation operation on the soil is stopped.

[0032] As Figure 6 shown, in this embodiment, drainage holes are vertically spaced apart on the side wall of the irrigation pipe 43. Water seepage holes 44 corresponding to the positions of the drainage holes are provided on the outer sleeve pipe 42. A drainage pipe is hermetically connected to the drainage hole in the direction facing the outer sleeve pipe 42. The outer end of the drainage pipe is slidably connected with an irrigation head, and the outer ends of the irrigation heads are in an arc structure. A micro spring is provided between the irrigation head and the irrigation pipe 43. The micro spring is sleeved on the drainage pipe, and its outer end is fixed to the irrigation head, so as to drive the irrigation head to slide in and out on the drainage pipe. An arc-shaped clamping seat 45 is fixed on the inner wall of the outer sleeve pipe 42. The middle of the arc-shaped clamping seat 45 corresponds to the connection hole, and a groove adapted to the irrigation head is provided in the middle of the arc-shaped clamping seat 45.

[0033] As the amount of water injected into the irrigation pipe increases, the irrigation pipe can be driven to move downward under the action of the gravity of the water, causing the top spring to be compressed. When the irrigation pipe 43 moves downward, it can synchronously drive each irrigation head to move downward. Thus, when the irrigation head moves into the groove of the arc-shaped clamping seat 45, the irrigation pipe 43 is communicated with the water seepage holes 44 on the outer sleeve pipe 42 through the drain pipe and the irrigation head, and the water in the irrigation pipe 43 flows into the outer soil synchronously through the water seepage holes 44. At this time, the gravity of the water in the irrigation pipe 43 is greater than the elastic force of the top spring 47. After irrigation is completed, the insertion rod 48 blocks the water inlet hole 49. When the water level in the irrigation pipe 43 drops below the warning line (the warning line is set on the irrigation pipe, that is, when the total weight of the water contained in the irrigation pipe is compared with the elastic force of the top spring, above the warning line, the top spring is compressed to water out through the water seepage holes, and below the warning line, the end of the irrigation head is pressed by the arc-shaped clamping seat and blocked without watering), the elastic force of the top spring 47 is greater than the gravity of the water in the pipe body. Thus, the irrigation pipe 43 drives each irrigation head to reset upward, and the micro spring on the drain pipe is compressed. At this time, each irrigation head moves out of the arc-shaped clamping seat 45 and is blocked, and no longer flows water out through the water seepage holes 44.

[0034] For the assembled seedling support device provided in this embodiment, when there is continuous rainfall in bad weather, the water accumulated in the ring sleeve cofferdam flows from the overflow channel 23 and is stored in the water storage tank 41, which can be used for watering operations on sunny days. It can also directly inject full tank of water into the water storage tank 41 by connecting an external water pump and water pipe (open the sealing plug on the water storage tank 41 before connecting the water pump to balance the pressure change in the tank body). During use, just adjust the insertion rod 48 up and down, which meets diverse needs and can also avoid the problem of uneven soil settlement caused by excessive water accumulation in the ring sleeve 2.

[0035] Embodiment 3, on the basis of Embodiment 2, this embodiment introduces the structure of the locking assembly 5, as Figure 6 shown, in this embodiment, the locking assembly 5 includes a rotating shaft 51, a locking sleeve 52, a pressing plate 53 and a locking seat 54. The rotating shaft 51 is rotatably installed on the top of the water storage tank 41 through the locking seat 54. A locking sleeve 52 is fixedly sleeved on the rotating shaft 51, and a pressing plate 53 is fixed on the side wall of the locking sleeve 52. When the insertion rod 48 drives the top plate 481 to move downward until the auxiliary spring 482 is compressed to the top surface of the water storage tank 41, the pressing plate 53 is toggled above the top plate 481 of the insertion rod 48 to lock and limit the top plate 481, which is convenient and fast.

[0036] Example 4. Based on Examples 1 - 3, this example further introduces the structure of the collar. The collar includes two semi-circular bases. One end of each of the two bases is provided with a socket, and the other end is provided with a plug adapted thereto. The water storage tank is also of a semi-circular structure and is respectively fixed on the outer side of the base. After the plugs on the two bases are inserted and fixed to the corresponding sockets, they are further locked and fixed with bolts, so that the water storage tank and the base can be butt-jointed and combined to form a ring structure. A gasket is arranged on the adjacent surfaces of the two bases to prevent water leakage from the water storage tank. To further strengthen the stability of the collar formed by the connection of the two bases, ear plates can also be welded on the side wall of the water storage tank. After the two semi-circular structures are butt-jointed and combined together, they are tightly fixed together by bolts threadedly connected to the ear plates, which is convenient for disassembly and assembly.

[0037] Example 5, as Figure 7 shown, this example provides another structure of the positioning sleeve, which includes a rectangular plate-like structure and an Ω-shaped positioning member. Rubber pads adapted to their shapes are fixed on their inner walls. They are locked and fixed together by bolts and screws and are jointly sleeved on the outer side of the tree trunk to facilitate clamping the tree trunk of the seedlings. The rectangular plate provides planar support, and the Ω-shaped member bears the curved surface stress. A mechanical balance is formed by multi-point locking with bolts, which can effectively resist lateral forces in different directions.
