Description

Technical Field

[0001] This invention relates to the field of seedling cultivation devices, and more specifically, to an integrated device for seedling cultivation and testing for forest planting based on intelligent control. Background Technology

[0002] Large-scale seedling cultivation of forest trees generally adopts the greenhouse container seedling cultivation model, but the supporting cultivation equipment and management system still have serious technical shortcomings. Existing functional modules related to forest seedling cultivation, such as irrigation, environmental monitoring, soil loosening, and oxygenation, are all independently and decentralized. Irrigation often uses a fixed sprinkler system in a greenhouse, which can only achieve large-area uniform spraying and cannot achieve precise irrigation according to the actual growth needs of individual seedlings. For the detection of soil moisture and oxygen content in the root zone, it mostly relies on manual sampling and offline testing with handheld testing equipment at regular intervals. This is not only cumbersome and costly, but also cannot achieve real-time and continuous online monitoring of root zone parameters for individual seedlings, and the test data has serious lag. For loosening soil compaction, it mostly relies on manual assistance or the use of small rotary tillage equipment on the surface, which can only act on the soil surface and cannot penetrate into the seedling root zone to achieve non-destructive loosening. The operation process is very likely to damage the tender roots of seedlings. As for the problem of root zone hypoxia, most existing technologies can only achieve passive aeration by loosening the soil, and cannot actively and precisely supply oxygen to the root zone soil.

[0003] The most significant problem with existing technologies is their inability to achieve integrated and coordinated control of seedling sprinkler irrigation, real-time root zone environment monitoring, soil loosening and improvement, and precise water and oxygen replenishment. This results in fragmented cultivation processes and a severe disconnect between environmental management and maintenance. This core issue directly prevents existing cultivation devices from forming a closed-loop management system of "real-time monitoring - intelligent analysis - coordinated control." They cannot simultaneously match irrigation, oxygenation, and soil loosening operations based on real-time soil moisture and oxygen content data in the root zone. This not only leads to extremely low operational efficiency and high labor and resource costs in large-scale seedling cultivation but also easily results in problems such as root zone moisture imbalance, soil compaction and oxygen deficiency, low water and fertilizer utilization, and poor root development. This causes industry pain points such as low seedling vigor, poor batch growth consistency, and insufficient afforestation survival rates. Furthermore, it fails to meet the refined environmental management requirements of rare native tree species and fast-growing, high-yield forest species, hindering the development of the forestry seedling industry towards intelligence, standardization, and large-scale production.

[0011] In a preferred embodiment of the present invention, the driving component includes a motor, a reducer, a first rack, a second rack, a gear ring, a driving half gear, and a rotating gear; the power output end of the motor is connected to the reducer, the driving half gear is fixed to the power output end of the reducer, the driving half gear is located between the two inserts, and a gear ring is fitted on each insert; the first rack and the second rack are slidably connected inside the incubation box, the first rack and the second rack are respectively located at the front and rear ends of the driving half gear, and the first rack and the second rack are both meshed with the gear rings on both sides; the rotating gear is located between the driving half gear and the second rack, and the rotating gear meshes with the second rack; the driving half gear meshes with the first rack and the rotating gear by rotation.

[0013] In a preferred embodiment of the present invention, the diameters of the first output port and the second output port increase sequentially from bottom to top.

[0014] In a preferred embodiment of the present invention, the two sides of the stirring rod are wedge-shaped.

[0015] The beneficial effects of this invention are as follows: This invention provides an integrated device for the cultivation and testing of forest tree seedlings based on intelligent regulation. It integrates four core functions into one device: foliar atomized irrigation, real-time online monitoring of root zone soil environment, non-destructive soil loosening and improvement in the root zone, and precise targeted water and oxygen supply. This solves the core technical problems of fragmented cultivation processes and serious disconnect between environmental control and maintenance operations in existing technologies. It constructs a complete closed-loop management system of "real-time monitoring - intelligent analysis - coordinated regulation", which greatly improves the automation and intelligence level of forest tree seedling cultivation, effectively reduces the manual operation costs and operational difficulties of large-scale seedling cultivation, and meets the standardized and large-scale cultivation needs of modern forestry seedling cultivation.

[0016] It achieves high-precision real-time detection and intelligent adaptive control of the root zone growth environment. Through the humidity and oxygen sensors integrated on the insertion tube that extends into the seedling root zone, it can continuously acquire the humidity and oxygen content data of the soil in the root zone of a single seedling in real time. There is no need for manual sampling and testing. This not only completely avoids the mechanical damage to the tender roots of seedlings caused by manual testing operations, but also allows the real-time detection data to be used as a direct basis for the control of irrigation, loosening of soil, and water and oxygen supply operations. It achieves dynamic and precise adaptation of the root zone growth environment, ensuring that the seedling roots are always in the optimal humidity and oxygen content environment, thereby avoiding problems such as drought, waterlogging and root rot, and poor development due to lack of oxygen from the root, and significantly improving the robustness of the seedling root system.

[0017] It achieves efficient and non-destructive loosening and improvement of root zone soil. By driving the rotation of the insert through the cultivation unit, and coordinating the opening and closing action of the stirring rod on the insert, the soil around the root zone can be evenly and gently stirred, effectively breaking up the soil compaction caused by long-term irrigation, greatly improving soil permeability, and providing a loose soil environment for root respiration and deep growth. At the same time, the soil loosening operation can be carried out simultaneously with water and oxygen replenishment operations, which can further improve the diffusion efficiency and uniformity of water and oxygen in soil pores, enhance the improvement effect of root zone environment, and achieve synergistic effect of soil loosening, water replenishment, and oxygen replenishment.

[0018] It achieves precise and directional replenishment of water and oxygen in the root zone. By controlling the alignment and switching of the first output port on the insert and the second output port on the drive cylinder, it can work with the second and third pipes to directly deliver water and oxygen to the root zone. This precisely delivers water and oxygen to the soil layer where the seedling roots are located. Compared with traditional surface spraying irrigation, it significantly improves the utilization rate of water, fertilizer and oxygen, effectively avoiding problems such as water and fertilizer evaporation loss, surface soil compaction and water waste caused by surface spraying. At the same time, it can specifically solve the problems of root rot and growth stagnation caused by deep soil hypoxia, and comprehensively improve the cultivation quality of seedlings.

[0019] The arc-shaped hinged irrigation frame, combined with the atomizing nozzles that correspond one-to-one with the cultivation troughs, enables uniform atomized spray irrigation of the seedling leaves. This not only meets the water needs of the above-ground parts of the seedlings but also regulates the local humidity of the cultivation environment. It complements the precise water and oxygen supply to the root zone, taking into account the synchronous growth needs of the above-ground stems and leaves and the underground roots of the seedlings, effectively improving the overall robustness of the forest seedlings and the survival rate after afforestation.

Detailed Implementation

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-6 As shown, this embodiment provides an integrated device for cultivating and detecting seedlings for forest planting based on intelligent control. The core structure includes a cultivation box 1, an irrigation structure, a cultivation net box, and cultivation units. The cultivation box 1 is a horizontal rectangular box structure with a hollow mounting cavity 12 inside. Multiple cylindrical cultivation grooves 11 are evenly spaced along the length of the top of the cultivation box 1. The bottom of the cultivation grooves 11 is connected to the mounting cavity 12. Each cultivation groove 11 is provided with a set of cultivation units. The cultivation net box can be detachably inserted into the cultivation groove 11. The cultivation units extend through the bottom of the cultivation net box into the internal cavity of the cultivation net box.

[0024] The cultivation cage is used for planting tree seedlings and supporting the substrate. It includes a first half 31 and a second half 32. The first half 31 and the second half 32 are semi-hollow cylindrical structures with identical and symmetrical designs. The vertical sides of the first half 31 and the second half 32 are hinged together. The other set of vertical sides of the first half 31 and the second half 32 are equipped with corresponding snap-fit ​​structures, which can realize the snap-fit ​​fixation of the two halves and quick opening and closing. The bottom of the first half 31 and the bottom center of the second half 32 are both provided with semi-circular openings. When the first half 31 and the second half 32 are snapped together, the two semi-circular openings are spliced ​​to form a complete circular through hole for the cultivation unit to pass through. The outer diameter of the cultivation net box after being snapped together is compatible with the inner diameter of the cultivation trough 11, and it can be stably inserted into the cultivation trough 11. Its internal cavity is used to fill the seedling substrate and the seedlings to be planted. When transplanting, the cultivation net box can be pulled out directly and the two halves opened to completely remove the seedlings with soil balls, avoiding root damage.

[0025] The irrigation structure is used for foliar atomized spray irrigation of tree seedlings, including an irrigation frame 21 and atomizing nozzles 22. The irrigation frame 21 is an arc-shaped frame, the curvature of which is adapted to the width of the cultivation box 1. One end of the irrigation frame 21 is hinged to the top end of the cultivation box 1 through a hinge seat. The irrigation frame 21 can be flipped up when loading or removing seedlings, making operation convenient. Multiple atomizing nozzles 22 are fixedly installed at equal intervals at the bottom of the irrigation frame 21. The number of atomizing nozzles 22 is exactly the same as the number of cultivation troughs 11, and the atomizing nozzles 22 and cultivation troughs 11 correspond one-to-one. The spray direction of each atomizing nozzle 22 is directly facing the seedling canopy in the cultivation trough 11 below. The water inlet end of the atomizing nozzle 22 is connected to an external water supply tank or water and fertilizer tank through a flexible water supply pipe.

[0026] The cultivation unit is the core functional component of this device, used to realize root zone environmental monitoring, soil loosening, and precise water and oxygen replenishment. It includes a drive unit, a plug 41, and a pusher unit. Each cultivation trough 11 is equipped with two symmetrically distributed inserts 41. The insert 41 is a hollow cylindrical structure with a closed upper end and an open lower end. The top of the insert 41 is conical to facilitate smooth insertion into the seedling substrate inside the cultivation net box. The insert 41 extends upward from the mounting cavity 12 through the through hole at the bottom of the cultivation trough 11 into the cultivation trough 11. The lower end of the insert 41 is connected to the drive component, which can drive the insert 41 to rotate around its own axis in both directions. The upper end of the insert 41 extends through the circular through hole at the bottom of the cultivation net box into the seedling substrate inside the cultivation net box. An oxygen sensor 52 and a humidity sensor 51 are installed on the outer wall of the conical top of the insert 41. Both the oxygen sensor 52 and the humidity sensor 51 are electrically connected to an external PLC controller, which can collect the humidity and oxygen content data of the core soil layer in the root zone of the seedling in real time, realizing online monitoring of the root zone growth environment.

[0027] The side wall of the insert 41 has multiple rectangular notches 42 at equal intervals from top to bottom. Each notch 42 is provided with a stirring rod 43. One end of the stirring rod 43 is fixedly connected to a drive wheel 44. The drive wheel 44 is rotatably connected to the inner walls of both sides of the notch 42 through a rotating shaft, and the toothed part of the drive wheel 44 extends through the notch 42 into the internal cavity of the insert 41. A drive cylinder 46 is coaxially inserted into the inside of the insert 41. The drive cylinder 46 is a hollow cylindrical structure with a closed upper end and an open lower end. The outer wall of the drive cylinder 46 is provided with multiple drive teeth 47 along the axial direction. The number of drive teeth 47 is the same as the number of drive wheels 44. The drive teeth 47 correspond one-to-one with the drive wheels 44, and the drive teeth 47 mesh with the corresponding drive wheels 44. When the drive cylinder 46 moves up and down along the axis of the insertion cylinder 41, it can drive the drive wheel 44 to rotate through the drive tooth 47, thereby driving the stirring rod 43 to swing around the axis, realizing the opening and retraction of the stirring rod 43. Both sides of the stirring rod 43 are wedge-shaped. When the stirring rod 43 opens outward, the wedge-shaped sidewalls can smoothly push away the surrounding seedling substrate, reducing the insertion and swing resistance. When the stirring rod 43 retracts inward, the wedge-shaped sidewalls can push away the substrate remaining in the notch 42, preventing the substrate from getting stuck in the notch 42 and affecting the opening and closing action of the stirring rod 43, thus ensuring the stability of the structure.

[0028] The pusher is used to drive the drive cylinder 46 to move axially, thereby controlling the opening and closing of the stirring rod 43 and the on / off control of the water-oxygen delivery channel. It includes a pusher rod 81, a synchronization plate 83, and a spring 82. The lower end of the drive cylinder 46 extends through the lower opening of the insert 41 to the bottom of the insert 41. The pusher rod 81 is vertically installed in the mounting cavity 12 of the incubation box 1. The upper end of the pusher rod 81 extends through the bottom of the incubation tank 11 to the inside of the incubation tank 11. The lower end of the pusher rod 81 is fixedly connected to the horizontally installed synchronization plate 83. The lower end of the drive cylinder 46 passes through the synchronization plate 83, and the drive cylinder 46 is rotatably connected to the synchronization plate 83 through a bearing, so that the drive cylinder 46 can rotate synchronously with the insert 41 and move up and down synchronously with the synchronization plate 83. The spring 82 is sleeved on the outside of the pusher rod 81, and the upper end of the spring 82 abuts against the inner top wall of the mounting box, and the lower end of the spring 82 abuts against the lower surface of the synchronization plate 83. When the cultivation net box is inserted into the cultivation tank 11, the bottom of the cultivation net box presses down against the upper end of the support rod 81, causing the synchronization plate 83 to move downward and compress the spring 82. The synchronization plate 83 drives the drive cylinder 46 to move downward synchronously, causing the stirring rod 43 to open outward. When the cultivation net box is pulled out, the spring 82 rebounds and resets, causing the synchronization plate 83 and the drive cylinder 46 to move upward, causing the stirring rod 43 to retract into the notch 42 and fit against the outer wall of the insertion cylinder 41.

[0029] Multiple first output ports 45 are provided on the inner wall of the notch 42 of the insert 41, and multiple second output ports 48 are provided on the wall of the drive cylinder 46. The number and opening height of the first output ports 45 and the second output ports 48 correspond one-to-one. The diameter of the first output ports 45 and the second output ports 48 increases from bottom to top to ensure that the soil layers at different depths in the root zone can obtain a uniform water and oxygen supply. When the drive cylinder 46 moves down to the fully open state of the stirring rod 43, the first output ports 45 and the second output ports 48 are fully aligned and connected to form a water and oxygen delivery channel. When the drive cylinder 46 moves up, the first output ports 45 and the second output ports 48 are misaligned, and the delivery channel is closed.

[0030] The lower end of the drive cylinder 46 is connected to the first pipe 62 via a rotary joint 61. The first pipe 62 is the main water and oxygen supply pipe. The two ends of the first pipe 62 are respectively connected to the lower ends of the two drive cylinders 46 corresponding to the same cultivation tank 11. The middle part of the main water and oxygen supply pipe is connected to the second pipe 63 (oxygen supply branch pipe) and the third pipe 64 (water and fertilizer supply branch pipe). Valves 65 are installed on both the oxygen supply branch pipe and the water and fertilizer supply branch pipe. In this embodiment, the valve 65 is a solenoid valve. The end of the oxygen supply branch pipe is connected to the external oxygen generation equipment for supplying oxygen. The end of the water and fertilizer supply branch pipe is connected to the external water and fertilizer supply equipment for supplying water or nutrient solution.

[0031] The driving component is used to drive the insert 41 to rotate in both directions to achieve soil loosening operation. It includes a motor, a reducer, a first rack 72, a second rack 75, a gear ring 71, a drive half gear 73, and a central rotating gear 74. The motor is fixedly installed in the mounting cavity 12 of the incubator 1. The power output end of the motor is fixedly connected to the input end of the reducer. The drive half gear 73 is fixedly installed in the power output end of the reducer. The drive half gear 73 is located between two corresponding inserts 41 in the same incubation tank 11. A gear ring 71 is fixedly sleeved on the lower outer wall of each insert 41. The first rack 72 and the second rack 75 are horizontally slidably connected to the inner wall of the mounting cavity 12 through a slide rail. The first rack 72 and the second rack 75 are located on the front and rear sides of the drive half gear 73, and the first rack 72 and the second rack 75 are respectively meshed with the gear ring 71 on the two inserts 41. The intermediate gear 74 is rotatably connected to the mounting cavity 12 through a rotating shaft. The intermediate gear 74 is located between the drive half gear 73 and the second rack 75. The intermediate gear 74 meshes with the second rack 75. The drive half gear 73 can alternately mesh with the first rack 72 and the intermediate gear 74 by rotating.

[0032] When the motor is working, it drives the drive half gear 73 to rotate continuously. When the drive half gear 73 meshes with the first rack 72, it drives the first rack 72 to move horizontally, and then drives the two inserts 41 to rotate synchronously in the forward direction through the gear ring 71. When the drive half gear 73 rotates to mesh with the intermediate gear 74, it drives the second rack 75 to move horizontally through the intermediate gear 74, and then drives the two inserts 41 to rotate synchronously in the opposite direction through the gear ring 71. This achieves the alternating forward and reverse rotation of the inserts 41, which drives the stirring rod 43 to evenly stir the substrate in the root zone and complete the soil loosening operation.

[0033] The specific working process of this invention is as follows: Seedling preparation stage: Flip up the irrigation frame 21, fasten the first half 31 and the second half 32 of the cultivation net box together, and fix them together to form a complete cavity. Fill the cultivation net box with seedling substrate, plant the forest seedlings in the substrate of the cultivation net box, and then insert the cultivation net box into the cultivation trough 11. The conical top of the insertion tube 41 smoothly passes through the through hole at the bottom of the cultivation net box and extends into the substrate. At the same time, the bottom of the cultivation net box presses down against the push rod 81, which drives the synchronous plate 83 and the drive cylinder 46 to move down. Through the meshing transmission of the drive tooth 47 and the drive wheel 44, the stirring rod 43 is driven to swing outward and open and insert into the substrate. At this time, the first output port 45 and the second output port 48 are completely aligned and connected, and the device enters the standby state.

[0034] Real-time monitoring stage: The humidity sensor 51 and oxygen sensor 52 at the conical top of the insert 41 collect the humidity and oxygen content data of the core soil layer in the root zone of the seedling in real time, and transmit the data to the external PLC controller to realize continuous online monitoring of the root zone growth environment.

[0035] Irrigation Operation Stage: When the controller detects that the substrate moisture is lower than the preset threshold, two irrigation modes can be activated: one is the foliar spray mode, where the atomizing nozzles 22 on the irrigation rack 21 are activated to uniformly atomize and spray the seedling leaves, meeting the water replenishment needs of the above-ground parts of the seedlings, while adjusting the humidity of the cultivation environment; the other is the root zone precision irrigation mode, where the controller opens the solenoid valve on the water and fertilizer delivery branch pipe, and water and fertilizer enter the drive cylinder 46 through the water and fertilizer delivery branch pipe and the water and oxygen delivery main pipe, and then are directly delivered to the substrate at different depths in the root zone through the aligned first output port 45 and second output port 48, realizing direct supply of water and fertilizer to the root zone and greatly improving the utilization rate of water and fertilizer.

[0036] During the soil loosening and oxygenation stage: When the controller detects that the substrate oxygen content is lower than the preset threshold, the controller activates the drive unit. The motor drives the drive half gear 73 to rotate. Through the transmission cooperation between the rack and pinion and the gear ring 71, the two inserts 41 rotate alternately in opposite directions. The inserts 41 drive the opened stirring rod 43 to rotate synchronously, which gently and evenly agitates the substrate in the root zone, effectively breaking up soil compaction and improving substrate permeability. At the same time, the solenoid valve on the oxygen delivery branch pipe can be opened, and oxygen is delivered through the pipeline to the drive cylinder 46 and directly delivered to the interior of the substrate through the output port to achieve active oxygenation in the root zone. Combined with the soil loosening operation, this further improves oxygen diffusion efficiency and quickly improves the hypoxic environment in the root zone.

[0037] Seedling transplanting stage: After the seedlings are cultivated, the irrigation frame 21 is opened and the cultivation net box is pulled directly out of the cultivation trough 11. At this time, the abutment rod 81 loses downward pressure, the spring 82 rebounds and resets, driving the synchronous plate 83 and the drive cylinder 46 to move upward, and the stirring rod 43 is retracted into the notch 42. Then, the buckle of the cultivation net box is opened, the first half 31 and the second half 32 are separated, and the seedling with the soil ball can be completely taken out. There is no need to forcibly remove the cup, which avoids root damage during the transplanting process from the root and can be used directly for afforestation transplanting.

[0038] Other techniques in this embodiment are based on existing technologies.
