Description

Technical Field

[0001] The present invention relates to the technical field of sunflower cultivation, in particular to a sunflower cultivation device and a cultivation method. Background Art

[0002] Sunflower flowers are not only suitable for ornamental purposes, but their seeds are also of greater economic value. They can be made into popular sunflower seeds and can also be used to produce high-quality edible sunflower oil that is low in cholesterol. In sunflower cultivation technology, the usability of the sunflower cultivation equipment is one of the key factors affecting the quality of the final sunflower product.

[0003] The existing Chinese patent application with publication number CN116784224A discloses a sunflower soilless cultivation device and method, including a sunflower soilless cultivation box, a card slot is reserved inside the sunflower soilless cultivation box, and the inside of the card slot is snap-connected with a first dividing plate, and the top of the first dividing plate is snap-connected with a second dividing plate, the side of the second dividing plate is provided with a latch, and the inside of the latch is snap-connected with the latch, the side of the sunflower soilless cultivation box is fixedly connected with a side connecting plate, and the top of the side connecting plate is integrally provided with a top connecting plate, and the top of the top connecting plate is provided with a motor control mechanism; the invention facilitates the separation of sunflowers according to their growth conditions, prevents the roots of sunflowers from entangled with each other or the intervals between sunflowers are too small to result in insufficient sunlight exposure for photosynthesis, and facilitates the protection of sunflowers and their cultivation devices, preventing heavy rain from washing away the sunflowers and culture solution.

[0004] However, the sunflower soilless cultivation device and method have the following defects when used: 1. When the device is in use, in order to protect the sunflowers from the impact of rain, a structure such as a canopy is used to block the sunflowers. However, the canopy is only used to block the rain and does not collect the rainwater. Since sunflowers also need water during the cultivation process, the cultivation device in the prior art is difficult to achieve effective recycling and reuse of rainwater, which wastes water resources to a certain extent and is difficult to respond to the current call for resource conservation. 2. Although sunflowers are plants that require sufficient sunlight, they also need an appropriate amount of sunlight during the seedling stage. The seedlings are relatively fragile and have limited tolerance to sunlight. Therefore, they need to avoid strong direct sunlight. At the same time, during the high temperature period in summer, sunflowers also need to avoid exposure to the sun. However, existing sunflower cultivation devices are difficult to perform adaptive shading according to the angle of sunlight and the intensity of direct sunlight, resulting in the roots of sunflowers or some leaves of sunflowers being exposed to strong sunlight, which is not conducive to improving the overall cultivation quality of sunflowers.

[0015] In addition, the present invention also provides a sunflower cultivation method, which adopts the sunflower cultivation device in the above scheme and specifically includes the following steps: S1: Cultivation: The interior of the inner box is partitioned or not partitioned according to the size of the sunflower plants to be planted, and then sunflowers are planted inside the inner box; S2: Liquid injection: A certain amount of nutrient solution or water is injected into the cavity through the liquid inlet, and then the nutrient solution or water flows into the interior of the outer box through the through-holes at the joint between the outer box and the liquid storage box, and supplies nutrients or water to the roots of the sunflowers in the inner box through the holes at the bottom of the inner box; S3: Sunshade: When sunshade is required, the third driving assembly is first used to flip the sunshade to a suitable position for sunshade, and then the second driving assembly is used to drive the baffle to move, thereby changing the position state of the first branch hole and the second branch hole being misaligned with each other, thereby completing the sunshade operation; S4: Rain shelter: When rain shelter is needed, first use the third driving component to flip the sunshade to a suitable position to shield the top of the sunflower from rain, and then use the second driving component to drive the baffle to move, so as to change the position state of the first branch hole and the second branch hole to complete the rainwater collection operation.

[0016] Compared with the existing technology, one or more of the above technical solutions have the following beneficial effects: 1. In this sunflower cultivation device and method, when the electric telescopic rod in the active component drives the second connecting block and the second piston to rise or fall, the first piston in the passive component can drive the first connecting block and the inner box to rise or fall, thereby creating a height difference between the bottom of the inner box and the nutrient solution level inside the outer box. This adjusts the nutrient solution infiltration conditions for the sunflower roots in the inner box, allowing adaptive adjustment according to the growth status of the sunflower at different stages. The provision of the electric telescopic rod makes the height adjustment of the inner box more precise, and facilitates the use of the entire cultivation device. 2. In the sunflower cultivation device and cultivation method, the sunshade in the sunshade and rain collection structure can not only serve as a sunshade, but also can shelter from rain and collect rain. After the baffle is arranged inside the central cavity, due to the cooperation between the first branch hole and the second branch hole, when shading is needed, the arrangement of the first branch hole and the second branch hole allows most of the light to be blocked, which not only prevents the sunflower from not being able to shine on the sunlight above it, but also can block most of the light when the sunlight is strong, ensuring the daily sunflower's need to face the sun. When it rains, the first branch hole allows rainwater to enter the second branch hole in the baffle, and each row of second branch holes is connected by a slit, so that rainwater can flow into the interior of the second chamber through the slit and enter the cavity through the hose, thereby realizing the collection of rainwater. Moreover, the first branch hole, the second branch hole and the slit are all small, and the three can all act as filtering structures, so that there are no large impurities in the rainwater that finally enters the cavity, which is convenient for subsequent mixing with nutrient solution. This responds to the current call for saving resources and is more conducive to the long-term lightweight use of the entire device. 3. In the sunflower cultivation device and cultivation method, the second driving component is provided to drive the baffle to move, so that the first branch hole and the second branch hole are aligned or offset with each other. When the sunlight is not strong or a large amount of rainwater needs to be collected, the first branch hole and the second branch hole are aligned to achieve a small degree of sunshade or a large amount of water collection. When the sunlight is strong or a large amount of rainwater does not need to be collected, the first branch hole and the second branch hole are offset to achieve a large degree of sunshade or a small amount of water collection. The entire structure is simple, easy to operate, and can be quickly adapted to different needs, resulting in a better overall use effect. 4. In the sunflower cultivation device and cultivation method, the first worm wheel and the first worm in the third drive assembly have a self-locking effect, so that the movement of the baffle is constrained by the rotation of the first worm, ensuring the stability of the baffle after it is moved. At the same time, the second worm wheel and the second worm in the fourth drive assembly also have a self-locking effect. Similarly, the adjustment of the overall angle of the sun visor is constrained by the rotation of the second worm, ensuring the stability of the sun visor after it is rotated. The combination of the two is conducive to the long-term use of the entire sunshade and rainwater collecting structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0021] See also Figures 1-17 A sunflower cultivation device includes a liquid storage tank 1, a cultivation structure 2, a sunshade and rain collection structure 3, and a third drive component 4, wherein: There are at least two cultivation structures 2 and they are symmetrically arranged on both sides of the liquid storage tank 1. The number of sunshade and rain-collecting structures 3 is the same as that of the cultivation structures 2 and they are arranged one by one directly above the cultivation structures 2. The number of third drive components 4 is the same as that of sunshade and rain-collecting structures 3 and they are matched one by one with the sunshade and rain-collecting structures 3. The third drive component 4 is arranged at the top of the liquid storage tank 1 and is used to drive the sunshade and rain-collecting structures 3 to rotate.

[0022] Furthermore, the liquid storage tank 1 is provided with cavities 11 having the same number as the cultivation structures 2, and the side of the liquid storage tank 1 is provided with liquid inlets 12 that are in one-to-one communication with the cavities 11; The cultivation structure 2 includes an outer box 21, an inner box 22 and a first drive assembly 23. The side of the outer box 21 is fixed to the side of the liquid storage tank 1. The inner box 22 penetrates the interior of the outer box 21 from top to bottom, and a plurality of holes 24 are opened on the inner bottom of the inner box 22. The first drive assembly 23 is used to drive the inner box 22 to rise or fall inside the outer box 21. In addition, the joints of the outer box 21 and the liquid storage tank 1 are both opened with through holes, which are used to connect the interior of the outer box 21 with the interior of the cavity 11. That is, when in use: The cultivation operation is as follows: the interior of the inner box 22 is partitioned or not partitioned according to the size of the sunflower plants to be planted, and then the sunflowers are planted inside the inner box 22; The liquid injection operation is specifically as follows: a certain amount of nutrient solution or water is injected into the interior of the cavity 11 through the liquid inlet 12, and then the nutrient solution or water flows to the interior of the outer box 21 through the through-holes at the joint between the outer box 21 and the liquid storage tank 1, and the nutrients or water are supplied to the sunflower roots inside the inner box 22 through the holes 24 at the bottom of the inner box 22, and the supply liquid level is not higher than the middle position of the inner box 22. Therefore, in this embodiment, the rear surface of the liquid storage tank 1 is also provided with a liquid outlet flush with the middle of the inner box 22, so that the supply liquid level is always not higher than the middle position of the inner box 22. Of course, correspondingly, the liquid inlet 12 can also be set at a position flush with the middle of the inner box 22, so that the liquid inlet 12 serves as both liquid inlet and liquid outlet functions.

[0023] Furthermore, in this embodiment, the first driving assembly 23 includes a passive component 231 and an active component 232, wherein: The passive component 231 includes a first fixed box 2311, a first piston 2312, a first connecting rod 2313 and a first connecting tube 2314. There are at least two first fixed boxes 2311. The first connecting tube 2314 is arranged between the two first fixed boxes 2311 and is used to connect the interiors of the two first fixed boxes 2311. The first piston 2312 is arranged inside the first fixed box 2311 to slide up and down. The bottom of the first connecting rod 2313 is fixed to the top of the first piston 2312, and the top of the first connecting rod 2313 passes through the outer top of the first fixed box 2311 and is fixed to the bottom of the inner box 22. In addition, the active component 232 is used to drive the first piston 2312 to rise or fall.

[0024] The active part 232 includes a second fixed box 2321, a second piston 2322, a second connecting rod 2323, a second connecting tube 2324 and an electric telescopic rod 2325. The second fixed box 2321 is fixed to the inside of the cavity 11, and the second piston 2322 is slidably arranged inside the second fixed box 2321. The bottom of the second connecting rod 2323 is fixed to the top of the second piston 2322, and the top of the second connecting rod 2323 passes through the outer top of the second fixed box 2321 and is connected to the output end of the electric telescopic rod 2325. The fixed end of the electric telescopic rod 2325 is fixed to the inside of the cavity 11, and one end of the second connecting tube 2324 is connected to the inside of the second fixed box 2321, and the other end of the second connecting tube 2324 is connected to the inside of one of the first fixed boxes 2311.

[0025] That is, when in use, after the electric telescopic rod 2325 is activated by the external controller, the electric telescopic rod 2325 can drive the second connecting rod 2323 and the second piston 2322 to rise or fall, and the space below the second piston 2322 and the space below the first piston 2312 are interconnected by the second connecting pipe 2324. Therefore, when the second piston 2322 falls, the first piston 2312 will rise, and when the second piston 2322 rises, the first piston 2312 will fall. When the second connecting block 44 and the second piston 2322 are driven to rise or fall, the first piston 2312 in the passive component 231 can drive the first connecting block 44 and the inner box 22 to rise or fall, thereby creating a height difference between the bottom of the inner box 22 and the level of the nutrient solution inside the outer box 21. This adjusts the nutrient solution infiltration conditions of the sunflower roots in the inner box 22, and can be adaptively adjusted according to the growth status of the sunflower at different stages. The provision of the electric telescopic rod 2325 makes the height adjustment of the inner box 22 more precise, making the entire cultivation device more convenient to use.

[0026] Furthermore, in this embodiment, a chute 211 is provided on the side of the outer box 21, and a slider 222 is fixed to the side of the inner box 22, which slidably engages with the chute 211. Furthermore, a scale line 212 is provided on the side of the outer box 21 facing the chute 211, and a reference line 223 is provided in the middle of the side of the slider 222, which mates with the scale line 212. When the height of the inner box 22 is adjusted, the slider 222 rises or falls and slides within the chute 211. At this time, the reference line 223 on the slider 222 can be compared with the scale line 212, allowing for a more intuitive observation of the raising or lowering of the inner box 22, thereby improving the overall usability.

[0027] Furthermore, the sunshade and rain collecting structure 3 includes a sun visor 31 and a baffle 32, wherein a first chamber 311 and a second chamber 313 are respectively provided at the left and right ends inside the sun visor 31, and a central chamber 312 for connecting the first chamber 311 and the second chamber 313 is provided at the center of the sun visor 31, and the baffle 32 is slidably arranged inside the central chamber 312, and a plurality of first branch holes 314 connected to the central chamber 312 are evenly provided on the top of the sun visor 31, and a plurality of second branch holes 321 matching the first branch holes 314 are evenly provided on the top of the baffle 32, and a slit 322 for connecting every two adjacent second branch holes 321 is also provided on the top of the baffle 32, and the end of the slit 322 is connected to the interior of the second chamber 313, and a hose 33 is connected to one end of the bottom of the sun visor 31 facing the second chamber 313, and one end of the hose 33 is connected to the interior of the second chamber 313, and the other end of the hose 33 is connected to the interior of the cavity 11.

[0028] In this embodiment, the sunshade 31 in the sunshade and rain collecting structure 3 can not only be used for sunshade, but also for rain shelter and rain collecting. After the baffle 32 is set inside the central cavity 312, due to the cooperation between the first branch hole 314 and the second branch hole 321, when sunshade is needed, the setting of the first branch hole 314 and the second branch hole 321 blocks most of the light, which not only avoids the sunflower from not being able to shine on the sunlight above it, but also blocks most of the light when the sunlight is strong, ensuring the sunflower's daily need to face the sun. When it rains, the first branch hole 314 can allow rainwater to enter. The second branch holes 321 in the baffle 32 are connected by slits 322 between each row of second branch holes 321, so that rainwater can flow to the inside of the second chamber 313 through the slits 322, and enter the cavity 11 through the hose 33, thereby realizing the collection of rainwater. Moreover, the first branch holes 314, the second branch holes 321 and the slits 322 are arranged as a whole and are small. All three can act as filtering structures, so that there are no large impurities in the rainwater that finally enters the cavity 11, which is convenient for subsequent mixing with nutrient solution, responding to the current call for saving resources and being more conducive to the long-term lightweight use of the entire device.

[0029] In addition, it is worth mentioning that in order to further facilitate the collection of rainwater, since the liquid storage tank 1 mentioned above is provided with a liquid outlet, an outlet pipe can be connected to the liquid outlet. When the rainwater is collected to a certain liquid level, the excess rainwater will flow out through the outlet pipe on the liquid outlet and be collected by an external rainwater collection box for subsequent recycling and reuse.

[0030] Furthermore, a biconcave lens 34 is disposed within the second branch hole 321, with a notch 35 defined on its side. The diameter of the first branch hole 314 decreases from top to bottom, while the diameter of the second branch hole 321 increases from top to bottom. Furthermore, a second drive assembly 36 is disposed within the first chamber 311 for driving the baffle 32. When the second drive assembly 36 drives the baffle 32, it can cause the first branch hole 314 and the second branch hole 321 to align or offset with each other. When sunlight is low or a large amount of rainwater needs to be collected, aligning the first branch hole 314 and the second branch hole 321 can achieve a small degree of sunshade or a large amount of water collection. When sunlight is high or a large amount of rainwater needs not to be collected, offsetting the first branch hole 314 and the second branch hole 321 can achieve a large degree of sunshade or a small amount of water collection. The overall structure is simple, easy to operate, and can be quickly adapted to meet different needs, resulting in a better overall user experience.

[0031] In the further optimization of this embodiment, the material of the bottom of the sun visor 31 is a light-uniforming material, which specifically refers to the light-uniforming plate material in the prior art. Since the overall structure of the first branch hole 314 and the second branch hole 321 is a conical structure, and a double concave lens 34 is provided inside the second branch hole 321, the double concave lens 34 has a divergent effect on light. Combined with the structure of the first branch hole 314, the structure of the second branch hole 321 and the material of the bottom of the sun visor 31, while providing sunshade, it also has the function of providing a certain amount of light to the top of the sunflower, and the notch 35 on the side of the double concave lens 34 facilitates the subsequent flow and collection of rainwater.

[0032] The second drive assembly 36 specifically includes a fixed plate 361, a first rotating shaft 362, a first worm 363, a second rotating shaft 364, a first worm gear 365, a first gear 366, a rack 367 and a guide rod 368, wherein the fixed plate 361 is fixed to the inside of the first chamber 311, the guide rod 368 and the rack 367 are both fixed to the end of the baffle 32 facing the first chamber 311, and the guide rod 368 passes through the fixed plate 361 and slides with the fixed plate 361. A rotating shaft 362 is rotatably connected to the fixed plate 361, and a second rotating shaft 364 is rotatably connected to the inside of the first chamber 311. The first worm 363 is sleeved on the outside of the first rotating shaft 362. The first worm wheel 365 and the first gear 366 are both sleeved on the outside of the second rotating shaft 364. The first worm wheel 365 is meshed with the first worm 363, and the first gear 366 is meshed with the rack 367. One end of the first rotating shaft 362 passes through the outside of the sun visor 31 and is connected to the first handle 369.

[0033] When the above-mentioned second drive assembly 36 is used, when the first shaft 362 is rotated by the first handle 369, the first worm 363 rotates accordingly, thereby causing the first worm wheel 365 to drive the second shaft 364 and the first gear 366 to rotate. When the first gear 366 rotates, the rack 367 moves, and under the action of the guide rod 368, the baffle 32 can be moved to adjust the relative position between the first branch hole 314 and the second branch hole 321. In addition, since there is a self-locking effect between the first worm wheel 365 and the first worm 363, the movement of the baffle 32 is constrained by the rotation of the first worm 363, and it cannot move alone, thereby making the baffle 32 have a good overall stability after being moved, which is beneficial to the long-term use of the entire sunshade and rain collection structure 3.

[0034] In addition, in order to improve the rain collection capacity of the entire sun visor 31, a drain slit 315 is opened on the side of the top of the sun visor 31 facing the second chamber 313, and a blocking plate 37 is also provided on the top of the sun visor 31 to cooperate with the drain slit 315. Through the setting of the blocking plate 37, the inclined sun visor 31 has a rainwater collection function, and the rainwater flows from the drain slit 315 to the inside of the second chamber 313 for subsequent collection.

[0035] Furthermore, in this embodiment, the third drive assembly 4 includes a mounting box 41, an opening 411, a first rotating rod 42, a second rotating rod 43, a connecting block 44, a flexible plate 45 and a control member 46, wherein the mounting box 41 is fixed to the top of the liquid storage tank 1, and the opening 411 is opened on the side of the mounting box 41 facing the sun visor 31, the first rotating rod 42 and the second rotating rod 43 are both rotatably connected to the inside of the mounting box 41, the connecting block 44 is sleeved on the outside of the first rotating rod 42, and the end of the connecting block 44 is fixed to the end face of the sun visor 31, one end of the flexible plate 45 is connected to the opening 411, and the other end of the flexible plate 45 is connected to the connecting block 44, and the control member 46 is used to control the rotation of the first rotating rod 42. The control member 46 includes a third rotating rod 461, a second worm 462, a second worm wheel 463 and a second gear 464, wherein the third rotating rod 461 is rotatably connected to the inside of the installation box 41, and the top of the third rotating rod 461 passes through the outer top of the installation box 41 and is connected to the second handle 465, the second worm 462 is sleeved on the outside of the third rotating rod 461, the second worm wheel 463 is sleeved on the outside of the second rotating rod 43 and meshes with the second worm 462, the outside of the second rotating rod 43 and the first rotating rod 42 are both sleeved with the second gear 464, and the second gear 464 on the outside of the second rotating rod 43 is meshed with the second gear 464 on the outside of the first rotating rod 42.

[0036] That is, when the third drive assembly 4 is used, after the third rotating rod 461 is rotated by the second handle 465, the second worm 462 rotates accordingly, causing the second worm gear 463 to drive the second rotating rod 43 and the second gear 464 on the second rotating rod 43 to rotate, thereby causing the first rotating rod 42 and the second gear 464 on the first rotating rod 42 to rotate, and the first rotating rod 42 drives the connecting block 44 to rotate, thereby causing the sun visor 31 to rotate accordingly, thereby completing the angle adjustment of the sun visor 31. Moreover, due to the self-locking effect between the second worm gear 463 and the second worm 462, the adjustment of the overall angle of the sun visor 31 is constrained by the rotation of the second worm 462, and the second worm 462 cannot rotate independently, thereby ensuring the stability of the sun visor 31 and facilitating the long-term use of the entire sunshade and rain-collecting structure 3.

[0037] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
