Description

Technical Field

[0001] This invention relates to the field of forestry seedling cultivation technology, specifically to methods for cultivating forestry seedlings. Background Technology

[0002] Currently, indoor seedling raising equipment mostly involves placing the seedlings directly in seedling trays. Staff then need to regularly spray water, nutrient solution, and pesticide solution using a watering can. For small-scale seedling raising, the pesticide solution can be mixed in a watering can before spraying. However, when raising a large number of seedlings, the solution is mixed manually and then sprayed using a watering can. Furthermore, some seedlings grow faster than others, requiring targeted mixing of the solution, which involves a significant amount of work.

[0003] In the prior art, patent document CN114208554B discloses a seedling raising device and method for afforestation in forestry engineering, including a cultivation frame, a turntable rotatably connected inside the cultivation frame, multiple liquid storage cylinders fixedly connected to the turntable, a ring mesh frame fixedly connected to the liquid storage cylinders, a movable plug slidably and sealingly connected to the liquid storage cylinders, a partition plate fixedly connected inside the liquid storage cylinders, the partition plate dividing the liquid storage cylinders into a nutrient solution chamber and a water chamber, and a movable culture dish placed on the movable plug, the movable culture dish containing... The aforementioned device contains nutrient soil, and the liquid medicine membrane ball can hold different liquid medicines. As the seedlings grow, the liquid medicines are automatically added to facilitate seedling cultivation. However, the aforementioned seedling cultivation device cannot adjust the seedling growth space and cultivation space according to the growth rate of the seedlings. At the same time, the existing device is not convenient for automatic ventilation, nutrient solution replenishment, and pest control of forestry seedlings. Furthermore, the existing device is not convenient for monitoring the growth rate and disease incidence of forestry seedlings. Based on this, the present invention provides a forestry seedling cultivation method to solve the problems mentioned in the background art. Summary of the Invention

[0004] This invention addresses the technical problems existing in the prior art by providing a method for cultivating forestry seedlings. It solves the problems that existing seedling raising devices cannot adjust the growth space and cultivation space of seedlings according to their growth rate, and that existing devices are not convenient for automatic ventilation, nutrient solution replenishment and pest control of forestry seedlings, and are also not convenient for monitoring the growth rate and disease status of forestry seedlings.

[0005] The technical solution of this invention to solve the above-mentioned technical problems is as follows: a method for cultivating forestry seedlings, comprising the following steps:

[0006] SS01, Planting seedlings: Regularly install the forestry seedlings to be cultivated onto the forestry planting and seedling cultivation device;

[0007] After steps SS02 and SS01, the forestry planting and seedling cultivation device drives the placed seedlings to rotate and revolve periodically, so that the forestry seedlings can receive supplemental light and ventilation and liquid in a cyclical manner.

[0008] SS03. Growth detection: During the cultivation of forestry seedlings, the visual detection probe built into the forestry seedling cultivation device performs image recognition on the forestry seedlings to measure the growth degree and disease severity of the forestry seedlings.

[0009] The forestry planting and seedling raising device includes a frame and a circulating frame. The circulating frame is rotatably connected to the frame and driven by a motor. A set of regularly distributed seedling raising mechanisms are installed on the circulating frame.

[0010] The seedling raising mechanism includes a hinge tube, which is rotatably connected to a circulation frame. A balancing frame is fixedly installed on the hinge tube. A pumping module, a spacing adjustment module, and a balancing block are fixedly installed on the balancing frame. A set of seedling-carrying modules are slidably connected on the balancing frame at positions corresponding to the pumping module and the spacing adjustment module. The spacing between two seedling-carrying modules is adjusted by the spacing adjustment module.

[0011] Corrugated connecting pipes are installed between each pair of seedling modules and between the pumping module and adjacent seedling modules;

[0012] The liquid supply component is used to deliver high-pressure gas-liquid mixture to the pump module;

[0013] Growth space adjustment component, used to control the gas pressure within the spacing module;

[0014] The image detection module is used for image recognition and detection of forestry seedlings.

[0015] Based on the above technical solution, the present invention can be further improved as follows.

[0016] Furthermore, the pumping module includes a pump cylinder with a hinged tube for fixed connection. A pump shaft is rotatably connected inside the pump cylinder. A set of pump blades arranged in a circular array are installed on the pump shaft at a position corresponding to the inner side of the pump cylinder. The pump cylinder is connected to the liquid supply component and the corrugated connecting pipe at the adjacent position. A transmission guide shaft is rotatably connected to the bottom of the pump cylinder. Both the transmission guide shaft and the bottom end of the pump shaft are equipped with linkage bevel teeth. The two linkage bevel teeth mesh with each other. Limiting springs are sleeved on the transmission guide shaft at positions corresponding to the pumping module and the adjacent seedling module, as well as at positions between two seedling modules.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, before use, the high pressure in the pump cylinder enters the gas-liquid mixture. After the gas-liquid mixture enters the pump cylinder, it drives the pump shaft to rotate through the pump blades. After the pump shaft rotates, it drives the transmission guide shaft to rotate. After the transmission guide shaft rotates, it drives the seedling module to work.

[0018] During operation, the spacing between two seedling modules and the spacing between the pump cylinder and adjacent seedling modules can be changed by adjusting the spacing module.

[0019] By changing the aforementioned spacing, this device can adjust the cultivation space for forestry seedlings according to their growth rate.

[0020] By adjusting the space for cultivating forestry seedlings, the cultivation cycle of this device can be extended to improve its functionality and the applicable cycle and scope of forestry seedling cultivation.

[0021] Furthermore, each seedling nursery has three seedling-carrying modules.

[0022] Furthermore, the seedling loading module includes a seedling cylinder, which is slidably connected to the balancing frame. The seedling cylinder has a fixedly opened ventilation outer cavity, and each ventilation outer cavity is connected to an adjacent corrugated connecting pipe. The inner wall of the ventilation outer cavity is rotatably connected to a loading cylinder. The loading cylinder has a fixedly opened ventilation inner cavity that communicates with the ventilation outer cavity. The top surface of the loading cylinder has a set of regularly distributed spray holes that communicate with the ventilation inner cavity. The loading cylinder has a fixedly opened top-opening cavity for placing forestry cultivation seedlings. The bottom surface of the loading cylinder is connected to the transmission guide shaft through a linkage component.

[0023] Furthermore, the linkage component includes a bottom shaft fixed to the bottom surface of the carrier cylinder, the bottom shaft being rotatably connected to the seedling cylinder, and a driven bushing being rotatably connected to the bottom of the carrier cylinder. The driven bushing has a guide shaft groove with openings at both ends and slidably connected to the transmission guide shaft. The cross-sections of the transmission guide shaft and the guide shaft groove are both regular polygons, and the axial direction of the spray hole is the same as the axial direction of the carrier cylinder.

[0024] Furthermore, the axial direction of the transmission guide shaft is the same as that of the hinge tube, the driven bushing is coaxial with the transmission guide shaft, and the axial direction of the bottom shaft is perpendicular to that of the transmission guide shaft.

[0025] The beneficial effect of adopting the above-mentioned further solution is that, during use, the setting of the balancing frame, hinge tube and balancing block enables the balancing frame to remain parallel to the horizontal plane during the rotation of the circulating frame and the movement of the balancing frame.

[0026] When the seedling module changes position, the transmission guide shaft and the guide shaft groove are set with regular polygonal cross sections, so that the transmission guide shaft can continuously drive the seedling cylinder.

[0027] During forestry seedling cultivation, the carrier tube rotates at a set speed. The rotation of the carrier tube ensures that the forestry seedlings receive light evenly, thereby improving the uniformity of their growth.

[0028] During seedling cultivation, the nozzle sprays out ventilation airflow or culture solution to supplement the cultivated forestry seedlings with ventilation and nutrient solution.

[0029] Furthermore, the liquid supply component includes a receiving tank and a storage tank fixed to the bottom of the frame. A ventilator is installed on the side of the storage tank. The storage tank contains culture medium and has a built-in aspiration pump. The outlet port of the aspiration pump is fixedly connected to a pumping pipe, and the outlet port of the ventilator is connected to a pumping air pipe. Both the pumping air pipe and the pumping liquid pipe are equipped with one-way valves. The other end of the pumping air pipe is connected to the pumping liquid pipe, and the other end of the pumping liquid pipe is connected to a fixed ring pipe. The inner wall of the fixed ring pipe is rotatably connected to a driven ring pipe. Both the fixed ring pipe and the driven ring pipe have annular cavities inside, and the two annular cavities are interconnected. High-pressure gas and liquid are supplied to the annular cavities through the pumping liquid pipe. The tail end of the hinged tube is rotatably connected to the annular cavity at the driven ring pipe through a rotary joint.

[0030] The beneficial effects of adopting the above-mentioned further scheme are that, during operation, the ventilator and the liquid suction pump work independently. After the ventilator starts working, ventilation operations are carried out on the forestry seedlings. Furthermore, through the realization of the ventilation function, the residual rate of pests on the forestry seedlings can be effectively reduced, thereby reducing the pest infestation of the forestry seedlings.

[0031] After the suction pump starts working, it then replenishes the culture medium for the forestry seedlings.

[0032] Furthermore, the distance adjustment module includes a corrugated airbag fixed on the balancing frame. The other end of the corrugated airbag is rotatably connected to a pump cylinder at an adjacent position. An air chamber is fixedly opened inside the corrugated airbag. The tail end of the air chamber is rotatably connected to an air guide pipe. The other end of the air guide pipe is connected to a growth space adjustment component.

[0033] Furthermore, the growth space adjustment component includes a pressure-controlled pump fixed on the liquid receiving tank, a pressure-controlled tube connected to the port of the pressure-controlled pump, a pressure-dividing cylinder installed on the pressure-dividing cylinder, a driven rotating cylinder rotatably connected to the pressure-dividing cylinder, a set of vent holes on the pressure-dividing cylinder, a pressure probe fixedly installed on the pressure-controlled tube, and the driven rotating cylinder fixedly connected to the air guide tube.

[0034] The beneficial effect of adopting the above-mentioned further solution is that, by setting the growth space adjustment component, the spacing between two seedling modules and the spacing between the pump cylinder and adjacent seedling modules can be precisely controlled, thereby precisely controlling the growth space and cultivation space of forestry seedlings.

[0035] Furthermore, the image detection module includes a detection frame slidably connected to the frame, a vertically arranged lifting push rod installed between the detection frame and the opposite surface of the frame, a screw drive module installed on the detection frame, a detection table connected to the screw drive module, a vision detection probe installed on the detection table, a PC host installed on the frame, an image recognition module built into the PC host, and the data terminal of the vision detection probe connected to the image recognition module.

[0036] The beneficial effect of adopting the above-mentioned further solution is that, when in use, by setting up the image detection module, the cultivation level, growth level and disease status of forestry seedlings can be identified through visual imaging detection.

[0037] The beneficial effects of this invention are:

[0038] 1. When the present invention is working, the spacing between two seedling modules and the spacing between the pump cylinder and the adjacent seedling module are changed by setting the spacing adjustment module. By changing the above spacing, the device can adjust the cultivation space of forestry seedlings according to the growth rate of forestry seedlings. By adjusting the cultivation space of forestry seedlings, the cultivation cycle of the cultivation device for forestry seedlings is improved, thereby improving the functionality of the device and the applicable cycle and scope of forestry seedling cultivation.

[0039] 2. In use, the balancing frame, hinge tube, and balancing block ensure that the balancing frame remains parallel to the horizontal plane during the rotation and movement of the circulating frame. During forestry seedling cultivation, the carrier cylinder rotates at a set speed, ensuring uniform light exposure for the seedlings and improving their growth uniformity. During seedling cultivation, the nozzles spray ventilation air or nutrient solution to supplement the airflow and nutrient solution for the cultivated seedlings. Furthermore, the ventilation function effectively reduces the residual rate of pests on the seedlings, thereby reducing the pest infestation level.

[0040] 3. When using this invention, the image detection module is set up to identify the cultivation level, growth level and disease status of forestry seedlings through visual imaging detection. The growth space adjustment component is set up to precisely control the spacing between two seedling modules and the spacing between the pump cylinder and adjacent seedling modules, thereby precisely controlling the growth space and cultivation space of forestry seedlings.

[0054] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0055] The present invention provides the following preferred embodiments.

[0056] like Figure 1-11 As shown, the forestry seedling cultivation method includes the following steps:

[0057] SS01, Planting seedlings: Regularly install the forestry seedlings to be cultivated onto the forestry planting and seedling cultivation device 1;

[0058] After steps SS02 and SS01, the forestry seedling cultivation device 1 drives the placed seedlings to rotate and revolve periodically, so that the forestry seedlings can receive supplemental light and ventilation and liquid in a cyclical manner.

[0059] SS03, Growth detection: During the cultivation of forestry seedlings, the visual detection probe 41 built into the forestry seedling cultivation device 1 performs image recognition on the forestry seedlings to measure the growth degree and disease severity of the forestry seedlings.

[0060] The forestry planting and seedling raising device 1 includes a frame 2 and a circulating frame 3. The circulating frame 3 is rotatably connected to the frame 2 and driven by a motor. A set of regularly distributed seedling raising mechanisms are installed on the circulating frame 3.

[0061] During operation, the circulation rack 3 rotates at a set cycle, thereby cyclically changing the placement and light-receiving position of each seedling unit.

[0062] This allows for cyclical light exposure across multiple seedling nurseries, thereby improving the uniformity of forestry seedling cultivation within each nursery.

[0063] The seedling raising mechanism includes a hinge tube 4, which is a hollow tubular structure with openings at both ends;

[0064] The hinge tube 4 is rotatably connected to the circulation frame 3. A balancing frame 5 is fixedly installed on the hinge tube 4. A pump-driven module, a spacing adjustment module, and a balancing block 43 are fixedly installed on the balancing frame 5. A set of seedling modules connected in series are slidably connected on the balancing frame 5 at the positions corresponding to the pump-driven module and the spacing adjustment module. The spacing between two seedling modules is adjusted by the spacing adjustment module.

[0065] Corrugated connecting pipes 6 are provided between each pair of seedling modules and between the pumping module and the adjacent seedling module;

[0066] The liquid supply component is used to deliver high-pressure gas-liquid mixture to the pump module;

[0067] Growth space adjustment component, used to control the gas pressure within the spacing module;

[0068] The image detection module is used for image recognition and detection of forestry seedlings.

[0069] The pumping module includes a pump cylinder 7 fixedly connected to a hinge tube 4. A pump shaft 8 is rotatably connected inside the pump cylinder 7. A set of pump blades 9 arranged in a circular array are installed on the pump shaft 8 at a position corresponding to the inner side of the pump cylinder 7. The pump cylinder 7 is connected to the liquid supply component and the corrugated connecting pipe 6 at the adjacent position. A transmission guide shaft 10 is rotatably connected to the bottom of the pump cylinder 7. Both the transmission guide shaft 10 and the bottom end of the pump shaft 8 are equipped with linkage bevel teeth. The two linkage bevel teeth mesh with each other. Limiting springs 11 are sleeved on the transmission guide shaft 10 at the positions corresponding to the pumping module and the adjacent seedling module, as well as at the positions between two seedling modules.

[0070] Before use, the high pressure in the pump cylinder 7 introduces gas and liquid. After the gas and liquid enter the pump cylinder 7, they drive the pump shaft 8 to rotate through the pump blade 9. After the pump shaft 8 rotates, it drives the transmission guide shaft 10 to rotate. After the transmission guide shaft 10 rotates, it drives the seedling module to work.

[0071] During operation, the spacing between two seedling modules and the spacing between the pump cylinder 7 and the adjacent seedling module can be changed by adjusting the spacing module.

[0072] By changing the aforementioned spacing, this device can adjust the cultivation space for forestry seedlings according to their growth rate.

[0073] By adjusting the space for cultivating forestry seedlings, the cultivation cycle of this device can be extended to improve its functionality and the applicable cycle and scope of forestry seedling cultivation.

[0074] Each seedling nursery has three seedling modules.

[0075] The seedling loading module includes a seedling cylinder 12, which is slidably connected to the balancing frame 5. A ventilation outer cavity 13 is fixedly opened inside the seedling cylinder 12. Each ventilation outer cavity 13 is connected to a corrugated connecting pipe 6 at an adjacent position. A loading cylinder 14 is rotatably connected to the inner wall of the ventilation outer cavity 13. A ventilation inner cavity 15 is fixedly opened inside the loading cylinder 14 and is connected to the ventilation outer cavity 13. A set of regularly distributed spray holes 16 are opened on the top surface of the loading cylinder 14 and are connected to the ventilation inner cavity 15. A cavity with a top opening for placing forestry cultivation seedlings is fixedly opened inside the loading cylinder 14. The bottom surface of the loading cylinder 14 is connected to the transmission guide shaft 10 through a linkage component.

[0076] The linkage assembly includes a bottom shaft 17 fixed to the bottom surface of the carrier cylinder 14. The bottom shaft 17 is rotatably connected to the seedling cylinder 12. A driven shaft sleeve 18 is rotatably connected to the bottom of the carrier cylinder 14. A guide shaft groove with open ends and slidably connected to the transmission guide shaft 10 is fixedly opened inside the driven shaft sleeve 18. The cross-section of the transmission guide shaft 10 and the guide shaft groove are both regular polygons. The axial direction of the transmission guide shaft 10 is the same as the axial direction of the hinge tube 4.

[0077] The axial direction of the nozzle 16 is the same as that of the carrier cylinder 14.

[0078] Driven bushing 18 is coaxially arranged with drive shaft 10, and the axial direction of bottom shaft 17 is perpendicular to the axial direction of drive shaft 10.

[0079] In use, the balancing frame 5, hinge tube 4 and balancing block 43 are set up so that the balancing frame 5 can remain parallel to the horizontal plane during the rotation of the circulating frame 3 and the movement of the balancing frame 5.

[0080] When the seedling module changes position, the transmission guide shaft 10 and the guide shaft groove are set with regular polygonal cross sections, so that the transmission guide shaft 10 can continuously drive the seedling cylinder 14.

[0081] During the cultivation of forestry seedlings, the carrier cylinder 14 rotates at a set speed. The rotation of the carrier cylinder 14 ensures that the forestry seedlings receive light evenly, thereby improving the uniformity of their growth.

[0082] During seedling cultivation, the nozzle 16 sprays out ventilation airflow or culture solution to supplement the cultivated forestry seedlings with ventilation and nutrient solution.

[0083] The liquid supply component includes a receiving tank 19 and a storage tank 20 fixed to the bottom of the frame 2. A ventilator 21 is installed on the side of the storage tank 20.

The other end of the pumping pipe 24 is connected to the pumping pipe 23. The other end of the pumping pipe 23 is connected to a fixed ring pipe 26. The inner wall of the fixed ring pipe 26 is rotatably connected to a driven ring pipe 27. Both the fixed ring pipe 26 and the driven ring pipe 27 have annular cavities 28 inside. The two annular cavities 28 are interconnected. High-pressure gas and liquid are sent into the annular cavity 28 through the pumping pipe 23. The tail end of the hinge tube 4 is rotatably connected to the annular cavity 28 at the driven ring pipe 27 through a rotary joint.

[0084] During operation, the ventilation fan 21 and the liquid suction pump 22 work independently. After the ventilation fan 21 starts working, it will then ventilate the forestry seedlings. Furthermore, through the ventilation function, it can effectively reduce the residual rate of pests on the forestry seedlings, thereby reducing the pest infestation of the forestry seedlings.

[0085] After the suction pump 22 starts working, it then replenishes the culture medium for the forestry seedlings.

[0086] The distance adjustment module includes a corrugated airbag 29 fixed on the balancing frame 5. The other end of the corrugated airbag 29 is rotatably connected to the pump cylinder 7 at the adjacent position. An air chamber is fixedly opened inside the corrugated airbag 29. The tail end of the air chamber is rotatably connected to the air guide pipe 30. The other end of the air guide pipe 30 is connected to the growth space adjustment component.

[0087] The growth space adjustment component includes a pressure-controlled pump 31 fixed on the liquid receiving tank 19.

A pressure probe 36 is fixedly installed on the pressure-controlled pipe 32. The driven rotating cylinder 34 is fixedly connected to the air guide pipe 30.

[0088] By adjusting the growth space components, the spacing between two seedling modules and the spacing between the pump cylinder 7 and the adjacent seedling module can be precisely controlled.

[0089] The image detection module includes a detection frame 37 slidably connected to the frame 2. A vertically arranged lifting push rod 38 is installed between the detection frame 37 and the opposite surface of the frame 2. A screw drive module 39 is installed on the detection frame 37.
