Description

Technical Field

[0001] This invention relates to the field of seedling equipment technology, and in particular to an intelligent temperature-controlled and moisture-retaining seedling cultivation device for desert ecological restoration. Background Technology

[0002] One important method for desert ecological restoration is vegetation planting. Before planting, the seedlings need to be artificially cultivated and transplanted into the desert to survive once they have reached the required conditions.

[0003] Unlike ordinary seedling cultivation, desert restoration plant seedlings need to be cultivated to have longer and less branched root systems in order to survive successfully after being transplanted into the desert. To achieve this cultivation goal, existing technologies cultivate seedlings in a relatively deep incubator at a fixed depth. By regularly watering the bottom of the incubator, the soil moisture content in the upper part of the seedling cultivation environment is low while the soil moisture content in the lower part is high, thereby inducing the plant roots to actively grow downwards.

[0004] The depth and water supply position of existing incubators are fixed and cannot be adjusted. The soil at the bottom of the incubator is often saturated with moisture because it is difficult to dissipate upwards. When the seedling roots grow downwards to a position near the bottom of the incubator, they will spread and grow in the water-rich soil, making it difficult to cultivate ideal seedlings with deep roots and very few branches. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent temperature- and humidity-controlled seedling cultivation device for desert ecological restoration, in order to solve the problem that the depth and water supply position of traditional desert vegetation seedling cultivation devices cannot be flexibly adjusted.

[0006] To achieve the above objectives, the present invention provides an intelligent temperature-controlled and moisture-retaining seedling cultivation device for desert ecological restoration, comprising a cultivation cylinder filled with sand, a lifting sleeve rod extending through the bottom of the cultivation cylinder, and a retractable and expandable water-proof component installed on the top of the lifting sleeve rod; The retractable waterproofing assembly includes a support chamber disposed outside the lifting sleeve rod. The support chamber has a support ring groove, and a fixed extension rod and a rotating rod are disposed within the support ring groove. The rotating rod pulls out the waterproofing ring plate that is wound inside the fixed extension rod. The lifting sleeve is equipped with a water inlet pipe inside, and the bottom end of the lifting sleeve is open so that the water inlet pipe is connected to the outside of the cultivation cylinder.

[0007] Further description of the intelligent temperature- and moisture-controlled seedling cultivation equipment for desert ecological restoration as described above: The inner wall of the cultivation cylinder is provided with several toothed protrusions arranged vertically at equal intervals. An outer protective sleeve is installed at the bottom of the cultivation cylinder, and the lifting sleeve passes through the cultivation cylinder and is located inside the outer protective sleeve.

[0008] Further description of the intelligent temperature- and moisture-controlled seedling cultivation equipment for desert ecological restoration as described above: The fixed extension rod extends horizontally to the inner wall of the cultivation cylinder. Each toothed ring has a groove, and the grooves of each toothed ring are opened in the same position. The thickness of the fixed extension rod is the same as the width of the groove of the toothed ring. The height of the fixed extension rod is greater than the distance between two adjacent toothed rings, so that the grooves of each toothed ring are arranged to form a guide groove for guiding the vertical movement of the fixed extension rod.

[0009] Further description of the intelligent temperature- and moisture-controlled seedling cultivation equipment for desert ecological restoration as described above: The distance between two adjacent toothed rings is the same as the height of the rotating rod. A toothed wheel is installed at the end of the rotating rod and inserted between the toothed rings. The toothed rings are arranged with teeth that cooperate with the toothed wheel.

[0010] Further description of the intelligent temperature- and moisture-controlled seedling cultivation equipment for desert ecological restoration as described above: The fixed extension rod has a radial cavity inside, and a conical roller is provided inside the radial cavity. The water-proof ring is wound around the conical roller, and a radially extending docking groove and a guide groove are provided above the radial cavity.

[0011] Further description of the intelligent temperature- and moisture-controlled seedling cultivation equipment for desert ecological restoration as described above: The docking groove and the guide groove extend horizontally outward to the outside of the fixed extension rod. The outward direction of the docking groove and the guide groove is opposite. The guide groove connects to the radial cavity. The size of the docking groove matches the rotating rod.

[0012] Further description of the intelligent temperature- and moisture-controlled seedling cultivation equipment for desert ecological restoration as described above: The water inlet pipe is integrally connected to the lifting sleeve rod. At least one fixed motor is installed inside the outer sleeve to drive the threaded rod to rotate axially. The outer peripheral wall of the lifting sleeve rod is provided with a threaded insertion channel, and the threaded rod is threadedly engaged with the threaded insertion channel.

[0013] Further description of the intelligent temperature- and moisture-controlled seedling cultivation equipment for desert ecological restoration as described above: The cultivation cylinder is equipped with an external control component. The main control unit of the control component can pump external water to the connecting pipe. The main control unit is electrically connected to the control cover covering the top of the cultivation cylinder.

[0014] Further description of the intelligent temperature- and moisture-controlled seedling cultivation equipment for desert ecological restoration as described above: The control cover includes a transparent housing with an exhaust fan mounted on top. A ventilation window is mounted above the exhaust fan, connecting the inner and outer spaces of the transparent housing. The exhaust fan is driven by a direct-controlled motor at the top of the ventilation window, which is electrically connected to the main control chassis via a detachable cable. Temperature and humidity probes are also installed around the exhaust fan, and both are electrically connected to the main control chassis.

[0015] Further description of the intelligent temperature- and moisture-controlled seedling cultivation equipment for desert ecological restoration as described above: The bottom of the water inlet pipe is provided with a threaded groove, and the top of the connecting pipe has a thread that matches the threaded groove.

[0016] In summary, due to the adoption of the above-mentioned technology, the beneficial effects of this invention—an intelligent temperature-controlled and moisture-retaining seedling cultivation device for desert ecological restoration—are as follows: 1. This invention provides a water-retaining and expanding component that can move vertically in sand within a cultivation cylinder. When water is supplied to the water-retaining and expanding component, the water is blocked by the water-retaining ring and cannot seep downwards. Instead, it spreads upwards due to soil capillary action, causing the soil moisture in the cultivation cylinder to decrease from bottom to top, effectively guiding the seedling roots to grow downwards. Since the water in the water-retaining and expanding component spreads upwards mainly due to capillary action, and a moisture probe is inserted in the soil, adjusting the water supply of the water-retaining and expanding component according to the soil moisture can achieve the effect of quickly adjusting the soil moisture.

[0017] 2. The water-retaining and expanding component of this invention can dynamically adjust the water supply position and the depth of the cultivation cylinder according to the seedling growth progress. In the early stage of seedling development, the water-retaining and expanding component supplies water at a high position, and the water quickly spreads to the top of the water-retaining ring. The sand below the water-retaining ring will not become saturated due to the downward flow of water. Thus, after the water-retaining and expanding component is adjusted according to the position of the seedling root system and water is supplied, the sand in the cultivation cylinder can still achieve a state of decreasing humidity from bottom to top. The seedling roots always grow in a growth environment of dry top and moist bottom, which enables them to grow quickly and effectively downwards and reduces branching. Attached Figure Description

[0020] 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.

[0021] like Figures 1-8 As shown, the present invention provides an intelligent temperature and humidity controlled seedling cultivation device for desert ecological restoration, including at least one cultivation cylinder 1, a placement rack 2 and a control component 3. When cultivating seedlings, the cultivation cylinder 1 is filled with sand 700. The cultivation cylinder 1 is placed on the placement rack 2. The control component 3 is connected to the cultivation cylinder 1 to supply water to the cultivation cylinder 1 and control the temperature and humidity for seedling growth.

[0022] Reference Figure 1-3 The placement rack 2 includes legs 21 and a placement plate 22. The placement plate 22 is horizontally supported by at least three legs 21. The placement plate 22 has a guide rail 201. The top periphery of the cultivation cylinder 1 has an expansion ring 11 with a diameter greater than the cylinder diameter. The width of the guide rail 201 is greater than the cylinder diameter of the cultivation cylinder 1 but smaller than the diameter of the expansion ring 11, so that multiple cultivation cylinders 1 can be placed on the guide rail 201 and arranged along the guide rail 201. The guide rail 201 has an outlet extending outward from the edge of the placement plate 22, so that each cultivation cylinder 1 can be removed from the placement plate 22 and scanned by the scanner 600 after several days of seedling cultivation. This allows the user to promptly monitor the root growth length of the plants in each cultivation cylinder 1, thereby making technical adjustments to the cultivation operation.

[0023] Preferably, the bottom of the expansion ring 11 has an annular groove for a plurality of balls 12 to be disposed therein. The balls 12 can roll freely in the annular groove. The balls 12 partially move out of the annular groove but cannot leave the annular groove, so that the bottom of the expansion ring 11 and the placement plate 22 can make rolling contact with each other by means of the balls 12, so that the cultivation cylinder 1 can move smoothly along the guide track 201.

[0024] The control component 3 includes a main control box 31, a water supply tank 32, and a control cover 33. The bottom of the cultivation tube 1 located on the placement rack 2 is connected to the water supply tank 32 via a connecting pipe 34, while the upper part is connected to the main control box 31 via the control cover 33. The root growth length data of the plants in each cultivation tube 1 obtained by the scanner 600 can be transmitted to the computer control assembly in the main control box 31 for comparison, recording, and processing, so that the computer control assembly in the main control box 31 can input appropriate control commands to different cultivation tubes 1, so that the plants in the cultivation tube 1 can be cultivated under ideal conditions.

[0025] The control cover 33 includes a transparent cover 331, a ventilation window 332, an exhaust fan 333, a temperature probe 334, and a humidity probe 335. Seedlings with pre-cultivated germinating roots are planted on top of a cultivation cylinder 1 filled with sand 700. The transparent cover 331 can cover the top of the cultivation cylinder 1, allowing light to pass through while protecting the newly sprouted buds of the seedlings. Preferably, the surface of the transparent cover 331 has a heat-insulating coating to further prevent sunlight from scorching the seedlings.

[0026] An exhaust fan 333 is installed at the top of the transparent cover 331, and a ventilation window 332 is installed above the exhaust fan 333. The ventilation window 332 connects the inner and outer spaces of the transparent cover 331 to ensure air circulation and dehumidification and heat dissipation inside the transparent cover 331. The exhaust fan 333 is driven by a direct-controlled motor 336 at the top of the ventilation window 332. The direct-controlled motor 336 is electrically connected to the main control chassis 31 through a detachable cable so that the operation of the exhaust fan 333 can be directly controlled by the main control chassis 31.

[0027] Temperature probe 334 and humidity probe 335 are also installed around the exhaust fan 333. Both temperature probe 334 and humidity probe 335 are electrically connected to the main control box 31. Temperature probe 334 can monitor the temperature inside the transparent cover 331 in real time. Humidity probe 335 has multiple detection points and can monitor the soil moisture at different depths after being inserted into the sand 700 in the cultivation tube 1. The data obtained by temperature probe 334 and humidity probe 335 will be received and processed by the main control box 31 to guide the operation of exhaust fan 333. The operation of exhaust fan 333 can change the heat dissipation rate inside the transparent cover 331 and the moisture evaporation rate on the surface of sand 700, thereby realizing the intelligent temperature and humidity control seedling cultivation function.

[0028] refer to Figure 4 and Figure 5 Preferably, before filling the cultivation cylinder 1 with sand 700, a pre-placed hopper 4 is placed inside. The pre-placed hopper 4 includes a top pull ring 41, a connecting beam 42, and a bottom ring 43. Multiple connecting beams 42 are symmetrically arranged around the circumference. The upper and lower ends of each connecting beam 42 are connected to the top pull ring 41 and the bottom ring 43, respectively, to form a stable cylinder. The perimeter and bottom of the pre-placed hopper 4 are surrounded by a mesh cloth 44. The mesh cloth 44 can isolate the sand 700 inside and outside the pre-placed hopper 4 but cannot isolate water, so that the soil inside and outside the pre-placed hopper 4 can exchange water and maintain a consistent humidity.

[0029] Each connecting beam 42 is hollow inside, forming a channel that extends upward to the outside. The top pull ring 41 has an insertion port 401 that connects to the inside of the connecting beam 42 and extends upward to the outside. The side wall of the connecting beam 42 has a window that connects to the internal channel, so that the humidity probe 335 can be inserted vertically into the connecting beam 42 and contact the soil through the window to monitor humidity. When the pre-set bucket 4 is set, after the seedling roots have grown to the required length, the top pull ring 41 can be pulled directly to remove the seedling along with the sand 700 from the cultivation cylinder 1 for transplanting. Preferably, the top pull ring 41, connecting beam 42, bottom ring 43 and mesh cloth 44 are all made of biodegradable materials so that they can degrade naturally after the seedlings are transplanted.

[0030] refer to Figure 4-8The inner wall of the cultivation cylinder 1 is vertically and equidistantly arranged with several toothed protrusions 15. An outer protective sleeve 13 is installed at the center of the bottom of the cultivation cylinder 1. A lifting sleeve 14 penetrating the bottom plate is installed on the outer protective sleeve 13. A water-blocking assembly 5 is installed on the top of the lifting sleeve 14.

[0031] The expansion and contraction waterproofing assembly 5 includes a liner chamber 51, a fixed extension rod 52, a rotating rod 53, and a waterproofing ring 54. The liner chamber 51 is spindle-shaped and coaxially disposed outside the top end of the lifting sleeve rod 14 to reduce the resistance of the sand 700 when the liner chamber 51 moves vertically with the lifting sleeve rod 14. A liner ring groove 501 is provided at the maximum outer diameter of the liner chamber 51. The ends of the fixed extension rod 52 and the rotating rod 53 are disposed in the liner ring groove 501. The fixed extension rod 52 has pointed ends on both the upper and lower sides so that the fixed extension rod 52 moves with the lifting sleeve rod 14. When moving vertically, it can push the sand 700 to better overcome resistance. The fixed extension rod 52 extends horizontally to the inner wall of the cultivation cylinder 1. Each toothed protrusion 15 has a slot that allows the end of the fixed extension rod 52 to be inserted. The slots of each toothed protrusion 15 are opened in the same position, and the thickness of the fixed extension rod 52 is the same as the width of the slot of the toothed protrusion 15. The height of the fixed extension rod 52 is greater than the distance between two adjacent toothed protrusions 15, so that the slots of each toothed protrusion 15 are arranged to form a guide groove for guiding the fixed extension rod 52 to move vertically.

[0032] The spacing between two adjacent toothed protrusions 15 is the same as the height of the rotating rod 53, forming a guide groove for guiding the rotating rod 53 to rotate axially around the lifting sleeve rod 14. The rotating rod 53 has a rhomboid cross-section and pointed ends at all four corners, so that the rotating rod 53 can push the sand 700 and better overcome resistance when it moves vertically with the lifting sleeve rod 14 and rotates axially around the lifting sleeve rod 14.

[0033] The fixed extension rod 52 has a radial cavity 502 inside, and a conical roller 55 is provided inside the radial cavity 502. The diameter of the conical roller 55 gradually increases from the end near the lifting sleeve rod 14 to the end near the inner wall of the cultivation cylinder 1. The water-proof ring plate 54 is wound around the conical roller 55. A radially extending docking groove 503 is provided above the radial cavity 502. The docking groove 503 extends horizontally outward toward the outside of the fixed extension rod 52. The size of the docking groove 503 matches the rotating rod 53 so that the rotating rod 53 can be completely moved into the docking groove 503.

[0034] The fixed extension rod 52 is also provided with a guide groove 504, which is connected to the radial cavity 502 and extends horizontally to the outside of the fixed extension rod 52. The opening height of the guide groove 504 is the same as that of the docking groove 503, but the opening direction is opposite to that of the docking groove 503. One side of the water-proof ring plate 54 is connected to the conical roller 55, and the other side of the water-proof ring plate 54 is pulled out of the fixed extension rod 52 along the guide groove 504 and connected to the side rib of the rotating rod 53. The guide groove 504 allows the rotating rod 53 to... The side ribs of the rotating rod 53 are inserted into the opening leading to the outside of the fixed extension rod 52. When the side ribs of the rotating rod 53 are inserted into the guide groove 504, the water-proof ring plate 54 is completely retracted and wound around the conical roller 55. The rotating rod 53 moves away from the fixed extension rod 52 and rotates around the lifting sleeve rod 14 for one revolution before being placed into the docking groove 503. The water-proof ring plate 54 that is pulled out will also be wrapped around and unfolded into a ring. The water-proof ring plate 54 is made of waterproof and soft materials such as plastic and silicone so that it can block the exchange of moisture between the sand 700 above and below the water-proof ring plate 54 after unfolding.

[0035] The lifting sleeve 14 is equipped with a water inlet pipe 56. The top of the water inlet pipe 56 is covered by a blocking top set at the top of the lifting sleeve 14, so that the water supply for plant growth can flow smoothly out of the upper outlet of the water inlet pipe 56 without being blocked by sand 700. The water inlet pipe 56 is integrally connected to the lifting sleeve 14 and can move up and down synchronously with the lifting sleeve 14. The lower end of the lifting sleeve 14 extends out of the cultivation cylinder 1 and is surrounded by the outer protective cylinder 13. At least one fixed motor 16 is installed inside the outer protective cylinder 13. The motor 16 is electrically connected to the main control box 31 to drive the threaded rod 17 to rotate axially. The outer peripheral wall of the lifting sleeve 14 is provided with a threaded insertion channel 101. The threaded rod 17 is threadedly engaged with the threaded insertion channel 101, thereby driving the lifting sleeve 14 to move vertically when the threaded rod 17 is driven to rotate axially. Preferably, multiple sets of fixed motors 16 and threaded rods 17 are provided. The number and position of the threaded insertion channels 101 correspond to the threaded rods 17 so that the lifting sleeve 14 can rise and fall stably.

[0036] It is understandable that, since the sand 700 is isolated from the top and bottom by the water-proof ring 54, the water supplied by the water inlet pipe 56 will mainly spread upward through soil capillary action. Adjusting the water supply according to the soil moisture can achieve the effect of maintaining and quickly adjusting the soil moisture. In the early stage of seedling development, the water-proof component 5 is set to supply water at a high position, and the water spreads upward to the water-proof ring 54. The sand 700 below the water-proof ring 54 will not become saturated due to the downward flow of water. Thus, after the water-proof component 5 is adjusted according to the position of the seedling root system and water is supplied, the sand 700 in the cultivation cylinder 1 can still achieve a state of decreasing moisture from bottom to top. The seedling roots always grow in a growth environment of dry top and moist bottom, which can quickly and effectively grow downward and reduce root branching.

[0037] refer to Figure 1 , Figures 4 to 8 The connecting pipe 34 includes a water supply pipe 341 that is connected to the water supply tank 32 and can be freely bent and extended, and a docking sleeve 342 for rigid connection with the water inlet pipe 56. The upper end of the water supply pipe 341 is inseparably installed on the docking sleeve 342. The docking sleeve 342 can rotate freely axially relative to the water supply pipe 341. The opening at the upper end of the water supply pipe 341 is connected to the inner cavity of the docking sleeve 342. Each connecting pipe 34 in the water supply tank 32 is equipped with a water pump that is independently controlled by the main control box 31. The water supply pipe 341 is connected to the water pump.

[0038] The bottom end of the lifting sleeve 14 has an opening that allows the water inlet pipe 56 to extend. The bottom of the water inlet pipe 56 is provided with a threaded groove 505. The top end of the docking sleeve 342 has a thread that matches the threaded groove 505. After the threaded groove 505 is screwed into the top end of the docking sleeve 342, the water supply pipe 341 can be connected to the water inlet pipe 56, thereby injecting external water into the cultivation cylinder 1.

[0039] refer to Figure 4 and Figure 7 The fixed extension rod 52 and the rotating rod 53 are respectively provided with a first waterproof motor 57 and a second waterproof motor 58 at the ends near the lifting sleeve rod 14. The first waterproof motor 57 is used to drive the conical roller 55 to rotate to release or rewind the water-proof ring 54. The rotating rod 53 is equipped with a toothed wheel 59 driven to rotate by the second waterproof motor 58 at the end away from the lifting sleeve rod 14. The toothed ring 15 has teeth arranged in a ring. The toothed wheel 59 can cooperate with the teeth of the toothed ring 15 to drive the rotating rod 53 to rotate around the lifting sleeve rod 14 axially during rotation.

[0040] The first waterproof motor 57 and the second waterproof motor 58 are electrically connected by wires installed in the lining groove 501. The first waterproof motor 57 is connected to the computer control assembly wires in the main control box 31 by wires embedded in the outer wall of the lifting sleeve rod 14, so that the retractable waterproof assembly 5 can be directly controlled by the main control box 31.

Any person skilled in the art who makes equivalent substitutions or changes to the intelligent temperature-controlled and moisture-retaining seedling cultivation device for desert ecological restoration and its inventive concept based on the present invention within the scope of the technology disclosed in the present invention should be covered within the scope of protection of the present invention.
