Description

Technical Field

[0001] This invention relates to the field of seedling technology, specifically to a seedling raising device for forestry. Background Technology

[0002] Forestry seedling raising devices are specialized equipment that integrate seedling containers and environmental control components. They are used to cultivate forest seedlings in an artificially controlled environment. They are the core equipment connecting forest seedlings, scions, and other propagation materials with transplantable seedlings. By simulating suitable light, water, and temperature conditions, they overcome the drawbacks of long seedling cycles, low survival rates, and seasonal limitations in natural environments. They are widely used in forestry production scenarios such as nursery seedling raising, rare tree species cultivation, and off-season seedling raising.

[0003] Current forestry seedling cultivation devices typically employ a unified lighting mode when using plant growth lamps for supplemental lighting. This mode uniformly illuminates all seedlings within the box. However, due to differences in light tolerance among seedlings of different tree species, even seedlings of the same species can exhibit varying growth patterns due to differences in genetics, substrate nutrients, and germination time. Some weaker seedlings are highly susceptible to physiological damage symptoms such as leaf curling, yellowing, and scorching edges due to excessive light exposure. This makes it difficult to implement timely dynamic shading control, thereby reducing the quality of seedling cultivation.

[0004] To address the above problems, a seedling raising device for forestry is proposed. Summary of the Invention

[0013] Furthermore, the drive assembly includes a dual-axis motor installed inside the seedling box.

[0019] 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.

[0020] To address the technical challenge of addressing the differences in light tolerance among seedlings of different tree species, which can lead to varying growth patterns even among seedlings of the same species due to variations in genetics, substrate nutrients, and germination time, and the susceptibility of weaker seedlings to physiological damage such as leaf curling, yellowing, and scorching from excessive sunlight, and the difficulty in timely dynamic shading control, thus reducing seedling quality, [further details needed]. Figures 1-12 As shown, the following preferred technical solutions are provided: like Figures 1-3 As shown, a forestry seedling raising device includes a seedling box 1, which can support and fix various components and cultivate seedlings. A controller is installed inside the seedling box 1 to control various electrical components. The controller is existing technology and is not shown in the figure. Several plant growth lights 2 are evenly arranged inside the seedling box 1. The plant growth lights 2 can provide suitable photosynthetic light sources for the forest seedlings in the seedling box 1 to meet the light requirements of different growth stages of the seedlings. A detection component 3 is installed inside the seedling box 1 to detect the growth status of the seedlings in real time. At the same time, it can detect the temperature and humidity inside the seedling box 1 to facilitate the judgment of whether the seedlings are experiencing unsuitable light conditions.

[0021] Several seedling components 4 are rotatably connected inside the seedling box 1. These components are used to hold tree seedlings. Several supporting rotating components 5 are also installed inside the seedling box 1. Several reflectors 6, made of highly reflective material, are installed at the bottom of each supporting rotating component 5 to reflect the light from the plant growth lamp 2, improving the uniformity of light within the seedling box 1 and supplementing the light requirements of the lower leaves of the seedlings. Several shading components 7 are installed at the top of each supporting rotating component 5. These shading components 7 can precisely shade individual seedlings that are not adequately exposed to light, preventing seedlings from developing eczema due to excessive light. The seedlings exhibit physiological damage such as leaf curling and yellowing. An adjustment component 8 is slidably installed on one side of the shading component 7. The adjustment component 8 can adjust the shading effect according to the condition of the seedlings. Several drive components 9 are installed inside the seedling box 1. A push component 10 is installed on one side of the drive component 9. The drive component 9 can drive the push component 10 to rise and fall, thereby causing the push component 10 to drive the reflector 6 and the shading component 7 to rotate respectively. This achieves precise and dynamic control of the light conditions of each tree seedling in the seedling box 1, and completes the supplemental lighting or shading operation as needed to adapt to the differentiated growth needs of the seedlings.

[0022] During use, the temperature and humidity inside the seedling box 1, as well as the growth status of each tree seedling, are monitored in real time through the cooperation between the detection component 3 and the controller.

[0023] Scenario 1: When the detection component 3 detects that the lower leaves of the seedling are weak due to insufficient light and require supplemental lighting, the controller causes the drive component 9 to move the push component 10 until the position of the push structure in several push components 10 corresponds to the position of the bottom of several reflectors 6. At this time, the controller causes several push components 10 to push several reflectors 6 respectively. During the pushing process, the drive component 9 rises synchronously, causing several reflectors 6 to rotate on the support rotation component 5, so that the bottom of several reflectors 6 gradually moves closer, thereby increasing the tilt angle of the reflectors 6. This makes the light from the plant growth lamp 2 more concentrated and reflects it to the lower leaves of the seedling, quickly supplementing the light required by the lower leaves. Compared with the existing technology that lacks precise supplemental lighting methods and relies on adjusting the light intensity or duration as a whole, it can specifically supplement the light of the lower leaves of seedlings with insufficient light, avoiding the energy waste caused by overall supplemental lighting, while ensuring that the upper and lower leaves of the seedling receive light evenly and promoting the healthy growth of the seedling.

[0024] Scenario 2: When the detection component 3 detects physiological damage such as leaf curling and yellowing in the seedlings, the controller resets several pushing components 10. At the same time, several reflectors 6 are reset simultaneously. Then, the controller extends several pushing components 10 a short distance and stops, so that the pushing structure in the pushing component 10 is directly below the driven structure in the adjusting component 8. At this time, the controller causes the driving component 9 to rise, and simultaneously pushes the adjusting component 8 to rise slowly until the snap-fit ​​structure in the adjusting component 8 snaps into the appropriate position. During this process, the shading structure in the adjusting component 8 and the shading structure in the shading component 7 gradually misalign, which can accurately adjust the shading area above the corresponding damaged seedling, and achieve on-demand shading to block the continuous damage of excessive light to the seedlings. Compared with the existing technology that relies on the overall shading net and cannot adjust the shading degree for individual seedlings, this technology can dynamically match the light needs of the damaged seedling, improve the overall quality of seedling cultivation and the survival rate of seedlings.

[0025] Then, the controller resets several pushing components 10, and the controller again drives the driving component 9 to drive the pushing components 10 to rise synchronously, so that the position of the pushing structure in the pushing component 10 corresponds to the position of the shading component 7. Then, the controller drives several pushing components 10 to push several shading components 7 respectively. During the pushing process, the driving component 9 descends synchronously, so that several shading components 7 rotate on the supporting rotating component 5, so that the tops of several shading components 7 gradually approach each other, which can achieve all-round and precise coverage of damaged seedlings, isolate excessive light, create a suitable low light environment for the recovery of physiological damage to leaves, and can specifically enhance the shading protection effect of individual damaged seedlings.

[0026] A rotating component 20 is provided on one side of the drive component 9. The rotating component 20 is fixedly connected to the seedling component 4. When the lower leaves are supplemented with light by several reflectors 6 and the damaged seedlings are precisely covered by several shading components 7, there will be some gaps between the reflectors 6 and the shading components 7. Therefore, before using the reflectors 6 and the shading components 7, the drive component 9 drives the rotating component 20 to rotate by the detection component 3 in conjunction with the controller. This makes the seedling component 4 and the seedlings inside rotate synchronously until they are adjusted to a suitable position. This allows the target light-receiving part of the seedling to be precisely aligned with the reflected light area of ​​the reflector 6, or the damaged leaves to correspond to the shading range of the shading component 7. This effectively avoids the problem of light leakage or poor shading effect caused by the gap between the reflectors 6 and the shading components 7. This can further improve the accuracy of light control, ensure that the lower leaves receive sufficient light when supplementing light, and protect the damaged parts when shading, thereby better protecting the growth status of the seedlings and improving the overall effectiveness of seedling cultivation.

[0027] like Figure 1 and Figure 3 As shown, a door 11 is rotatably connected to one side of the seedling box 1. The door 11 can close the seedling box 1 to maintain the stability of the seedling environment such as temperature, humidity and light inside the box. At the same time, it is convenient for operators to take out and put in the seedling components 4 and to inspect the internal parts of the box. A drain pipe 12 is connected to one side of the seedling box 1. A drain chamber is set inside the seedling box 1. The drain pipe 12 is connected to the drain chamber. The drain pipe 12 is used to drain excess water seeping out of the seedling components 4 to avoid water accumulation in the box and affecting the root growth of the seedlings.

[0028] like Figure 2 As shown, the detection component 3 includes two vision sensors 31 installed opposite each other on the inner wall of the seedling box 1. The vision sensors 31 can collect images of the growth status of each tree seedling in real time, such as abnormal conditions such as leaf curling and yellowing. At the same time, its lens is equipped with a filter structure to avoid the light from the plant growth lamp 2 from interfering with the detection accuracy. A temperature and humidity sensor 32 is installed in the seedling box 1. The temperature and humidity sensor 32 can collect the temperature and humidity data in the seedling box 1 in real time and transmit the data to the controller to provide environmental parameter basis for the control operations such as light, supplemental light and shading.

[0029] like Figure 4 and Figure 7As shown, the seedling component 4 includes a rotating cylinder 41 rotatably connected to the seedling box 1. The top of the rotating cylinder 41 has several positioning grooves 42. A seedling tube 44 is slidably connected inside the rotating cylinder 41. Several positioning blocks 43 are fixedly connected to the bottom of the upper opening edge of the seedling tube 44. The positioning blocks 43 are connected to the positioning grooves 42. A drainage hole 45 is opened through the bottom of the seedling tube 44. The drainage hole 45 can drain excess water in the seedling tube 44 in time, avoid water accumulation in the substrate which will cause the seedling roots to rot, and at the same time ensure the permeability of the substrate, creating a humid and breathable suitable environment for the growth of seedling roots, so as to promote the healthy development of seedling roots.

[0030] like Figures 8-9 and Figures 11-12 As shown, the supporting rotation assembly 5 includes several support rods 51 fixedly connected inside the seedling box 1. Each support rod 51 has an arc-shaped rod 52 fixedly connected to its top. Both ends of the arc-shaped rod 52 are fixedly connected to a rotating shaft 53. The outer walls of two adjacent rotating shafts 53 are rotatably connected to an arc-shaped rotating rod 54. One end of each of the two rotating shafts 53 is fixedly connected to a torsion spring 55, and the other end of the torsion spring 55 is fixedly connected to a connecting post 56. After the pushing assembly 10 releases the push on the arc-shaped rotating rod 54, the torsion spring 55 can automatically reset the arc-shaped rotating rod 54 and the connected reflector 6 and shading assembly 7 to their initial state. The connecting post 56 is fixedly connected to the inner wall of the arc-shaped rotating rod 54, and the reflector 6 is fixedly connected to the bottom of the arc-shaped rotating rod 54.

[0031] like Figures 4-6 and Figures 8-12 As shown, the light-shielding component 7 includes a rotating plate 71 fixedly connected to the top of the arc-shaped rotating rod 54. A first conical light-shielding plate 72 is fixedly connected to the top of the rotating plate 71. The first conical light-shielding plate 72 has several first through holes 73. A rubber block 74 is fixedly connected to the outer wall of the first conical light-shielding plate 72. The rubber block 74 can buffer the light-shielding component 7 when the pushing component 10 contacts it, avoiding damage to the component due to hard collision. It can also enable the pushing component 10 to smoothly push the light-shielding component 7 to complete the rotation adjustment, ensuring the stable operation of the light-shielding control.

[0032] like Figures 5-6 , Figure 8 and Figures 11-12As shown, the adjustment assembly 8 includes a slider 82 slidably connected to one side of the first conical light-shielding plate 72. A second conical light-shielding plate 81 is fixedly connected to one side of the slider 82. The second conical light-shielding plate 81 has several second through holes 83. The diameter of the second through holes 83 is the same as that of the first through holes 73. When no light-shielding operation is performed, the positions of the second through holes 83 and the first through holes 73 correspond. A fixing post 84 is fixedly connected to the top of the rotating plate 71. A sliding post 85 is slidably connected inside the fixing post 84. 5 is fixedly connected to the bottom of the second conical light shield 81. The inner wall of the fixed column 84 is provided with several arc-shaped slots 86. The sliding column 85 has two arc-shaped blocks 88 that are slidably connected to each other. The arc-shaped blocks 88 and the arc-shaped slots 86 are matched in shape. A spring 87 is fixedly connected to one side of each of the two arc-shaped blocks 88, and the other end of the spring 87 is fixedly connected to the sliding column 85. A driven plate 89 is fixedly connected to one side of the second conical light shield 81. The driven structure in the above-mentioned adjustment assembly 8 is the driven plate 89.

[0033] like Figure 4 and Figure 8 As shown, the drive assembly 9 includes a dual-axis motor 91 installed inside the seedling box 1. A protective cover 92 is fixedly connected inside the seedling box 1, covering the outside of the dual-axis motor 91. A threaded rod 93 is fixedly connected to the upper output end of the dual-axis motor 91, and the threaded rod 93 is rotatably connected to the seedling box 1. A threaded block 94 is threadedly connected to the outer wall of the threaded rod 93. A limit rod 95 is fixedly connected inside the seedling box 1, and the threaded block 94 is slidably connected to the limit rod 95. A connecting seat 97 is fixedly connected to the top of the limit rod 95. The threaded rod 93 is rotatably connected to the connecting seat 97. Both sides of the threaded block 94 are fixedly connected to bellows 96. The bellows 96 can protect the threaded rod 93 and prevent dust from entering and affecting the transmission. One end of each of the two bellows 96 is fixedly connected to the inner wall of the seedling box 1 and the connecting seat 97, respectively. A support frame 98 is fixedly connected to one side of the threaded block 94. The dual-axis motor 91 is a dual independent axis motor. It drives the threaded rod 93 to drive the push assembly 10 to move through two independent output shafts, and drives the rotating assembly 20 to rotate.

[0034] like Figures 8-10As shown, the pushing component 10 includes an oil storage box 101 fixedly connected to the seedling box 1. An electric push rod 102 is installed on one side of the oil storage box 101. A first piston 103 is slidably connected inside the oil storage box 101. The movable end of the electric push rod 102 is fixedly connected to the first piston 103. A hose 104 is connected to one side of the oil storage box 101. The hose 104 is a lightweight metal hose 104, which has good flexibility and structural stability. It can prevent bending when the pushing component 10 moves up and down, and provide reliable hydraulic power for the smooth extension and retraction of the pushing structure in the pushing component 10. One end of the hose 104 is connected to a branch pipe 105. The branch pipe 105 is fixedly connected to the bottom of the support frame 98. Several oil outlet pipes 106 are evenly connected to one side of the branch pipe 105. Several connecting pipes 107 are fixedly connected to the outer wall of the support frame 98. The oil outlet pipes 106 are connected to the connecting pipes 107. A second piston 108 is slidably connected inside the connecting pipes 107.

[0035] The second piston 108 is fixedly connected to a push rod 109 at one end. The push rod 109 is slidably connected to the connecting pipe 107 and the support frame 98 respectively. When no supplementary lighting or shading operation is performed, the oil reservoir 101, hose 104 and branch pipe 105 are filled with hydraulic oil to ensure the sealing and pressure transmission stability of the hydraulic system. This allows the push assembly 10 to quickly transmit hydraulic power to drive the push rod 109 when supplementary lighting or shading adjustment is needed, avoiding response lag due to air or lack of oil in the system. This ensures the timeliness and accuracy of lighting control. The support frame 98, connecting pipe 107 and oil outlet pipe 106 are all made of lightweight materials, which can reduce the load when the drive assembly 9 drives the push assembly 10 to rise and fall, alleviate the imbalance of torque on both sides, and thus extend the service life of the device. Both the first piston 103 and the second piston 108 are equipped with sealing rings to seal and prevent leakage. The sealing rings are existing technology and are not shown in the figure.

[0036] During use, the temperature and humidity conditions inside the seedling box 1, as well as the growth status of each tree seedling, are monitored in real time through the cooperation of two vision sensors 31, temperature and humidity sensor 32 and controller.

[0037] Scenario 1: When two vision sensors 31, in conjunction with temperature and humidity sensor 32, detect that the lower leaves of the seedlings are weak due to insufficient light and require supplemental lighting, the controller activates the dual-axis motor 91 to rotate the threaded rod 93. This causes the threaded block 94, limited by the limit rod 95, to move the support frame 98 and the pushing assembly 10 until the positions of several push rods 109 correspond to the bottom positions of several reflectors 6. At this point, the controller activates the electric push rod 102 to move the first piston 103. The first piston 103 then forces the hydraulic oil in the oil reservoir 101 through the branch pipe 105 into several oil outlet pipes 106, and drives the second piston 108 to push the push rods 109 gradually out of the connecting pipe 107, thereby pushing several reflectors 6. During this pushing process, the dual-axis motor 91... 1. This allows the threaded block 94 and the support frame 98 to rise synchronously, adapting to the height changes of the reflector 6 as it rotates with the arc-shaped rotating rod 54. This ensures that the push rod 109 maintains stable contact with the reflector 6 and continuously applies thrust, causing several reflectors 6 to drive the arc-shaped rotating rod 54 to rotate on the rotating shaft 53. Simultaneously, this stores energy for the torsion spring 55, causing the bottoms of several reflectors 6 to gradually approach each other, thereby increasing the tilt angle of the reflectors 6. This allows the light from the plant growth lamp 2 to be reflected more concentratedly onto the lower leaves of the seedlings, quickly supplementing the light required by the lower leaves. Compared to existing technologies that lack precise supplemental lighting, this method, which relies on adjusting the overall light intensity or duration, can specifically supplement the light to the lower leaves of seedlings that are lacking sufficient light, avoiding the energy waste caused by overall supplemental lighting. At the same time, it ensures that the upper and lower leaves of the seedlings receive light evenly, promoting the healthy growth of the seedlings.

[0038] Meanwhile, the extension length of the push rod 109 can be dynamically adjusted to a suitable length according to needs, thereby driving the reflector 6 to rotate to different angles. It can precisely match the reflection angle of the reflector 6 to adjust the supplementary light intensity according to the specific degree of insufficient light on the lower leaves of the seedling. Compared with the extensive overall light adjustment method in the existing technology, it can realize personalized supplementary light control for single or local seedlings, further improving the accuracy and flexibility of supplementary light, avoiding energy waste, and better adapting to the differentiated light needs of seedlings with different growth stages.

[0039] Scenario 2: When the two visual sensors 31, in conjunction with the temperature and humidity sensor 32, detect physiological damage such as leaf curling and yellowing in the seedlings, the controller resets several push components 10. During the reset process, the electric push rod 102 retracts, gradually drawing the hydraulic oil squeezed into the connecting pipe 107 back into the oil storage box 101. At this time, the second piston 108 drives the push rod 109 to gradually retract into the connecting pipe 107. Then, through the reset of the torsion spring 55, several reflectors 6 are reset synchronously. Subsequently, the controller causes several electric push rods 102 to extend a short distance, driving the push rod 109 to extend a short distance synchronously before stopping, so that the position of the push rod 109 is directly below the driven plate 89. At this time, the controller causes the drive component 9 to rise, which in turn pushes the driven plate 89 to rise slowly and synchronously. This causes the arc-shaped locking block 88 to gradually overcome the resistance of the spring 87 and engage with the arc-shaped locking slot 86 at the bottom until it is engaged in the appropriate position. During this process, the second through hole 83 and the first through hole 73 gradually misalign, which can precisely adjust the shading area above the corresponding damaged seedling. This allows for on-demand shading to block the continuous damage of excessive light to the seedling. Compared with the existing technology that relies on the overall shading net and cannot adjust the shading degree for individual seedlings, this technology can dynamically match the light requirements of the damaged seedling, improving the overall quality of seedling cultivation and the survival rate of seedlings.

[0040] Then, the controller resets several electric push rods 102, and the controller again drives the drive assembly 9 to synchronously raise the push rods 109, so that the position of the push rods 109 corresponds to the position of the rubber block 74. Subsequently, the controller drives several electric push rods 102 to push the rubber block 74 respectively. During the pushing process, the dual-axis motor 91 causes the threaded block 94 and the support frame 98 to descend synchronously, which can adapt to the height change of the first conical light-shielding plate 72 as the rotating plate 71 and the arc-shaped rotating rod 54 rotate, ensuring that the push rods 109 stably push the first conical light-shielding plate 72 to rotate through the rubber block 74, so that several rotating plates 71 and arc-shaped rotating rods 54 rotate on the rotating shaft 53, so that the tops of several first conical light-shielding plates 72 gradually approach each other, which can achieve all-round and precise coverage of damaged seedlings, isolate excessive light, create a suitable low-light environment for the recovery of physiological damage to leaves, and can specifically enhance the light-shielding protection effect of individual damaged seedlings.

[0041] After the seedlings are shaded by the first conical shade plate 72 for a period of time, the controller will reset the push component 10 and detect it again through the two vision sensors 31, the temperature and humidity sensor 32 and the controller. If no further shading is needed, the drive component 9 will drive the push component 10 to reset, in preparation for subsequent supplemental lighting and shading operations.

[0042] When the positions of the second through hole 83 and the first through hole 73 need to be reset, the controller causes the push rod 109 to move above the driven plate 89. At this time, the controller causes several electric push rods 102 to extend a short distance, driving the push rod 109 to extend a short distance simultaneously and then stop, so that the position of the push rod 109 is directly above the driven plate 89. At this time, the controller causes the drive assembly 9 to descend, and at the same time pushes the driven plate 89 to descend slowly and synchronously, so that the positions of the second through hole 83 and the first through hole 73 are re-aligned, which facilitates the reset of the second conical light shield 81.

[0043] To address the technical problem of gaps existing during supplemental lighting and shading, which affect cultivation results, such as... Figures 3-4 and Figure 7 As shown, the following preferred technical solutions are provided: like Figure 4 and Figure 7 As shown, the rotating assembly 20 includes a rotating shaft 201 fixedly connected to the lower output end of the dual-axis motor 91. A first gear 202 is fixedly connected to one end of the rotating shaft 201, and a second gear 203 is fixedly connected to the outer wall of the rotating drum 41. The second gear 203 meshes with the first gear 202.

[0044] When supplementing the lower leaves with light using several reflectors 6 and precisely covering damaged seedlings with several first conical shading plates 72, there will be gaps between the reflectors 6 and the first conical shading plates 72. Therefore, before using the reflectors 6 and the first conical shading plates 72, two vision sensors 31 and a temperature and humidity sensor 32, in conjunction with a controller, cause the dual-axis motor 91 to drive the rotating shaft 201 and the first gear 202 to rotate. The second gear 203 meshes with the first gear 202, driving the second gear 203 and the rotating drum 41 to rotate, thus causing the rotating drum... 41 rotates inside the seedling box 1, causing the seedling tube 44 and the seedlings inside to rotate synchronously until they are adjusted to a suitable position. This allows the target light-receiving part of the seedling to be precisely aligned with the reflected light area of ​​the reflector 6, or to align the damaged leaves with the shading range of the first conical shading plate 72. This effectively avoids the problem of light leakage or poor shading effect caused by the gap between the reflector 6 and the first conical shading plate 72, and can further improve the accuracy of light control. This ensures that the lower leaves receive sufficient light when supplementing light, and that the damaged parts are properly protected when shading, thereby better protecting the growth status of the seedlings and improving the overall effectiveness of seedling cultivation.
