Description

Technical Field

[0001] This invention relates to the field of strawberry cultivation technology, and more particularly to a soilless strawberry cultivation device. Background Technology

[0002] Soilless cultivation of strawberries has been widely used in modern agriculture due to its advantages, such as avoiding continuous cropping obstacles, improving fruit quality, and reducing pests and diseases. Existing soilless strawberry cultivation devices typically use planting baskets to fix the plants and utilize circulating liquid fertilizer to provide nutrients.

[0003] In the prior art, there exists a solution such as the planting device for hydroponics of strawberries described in patent announcement number CN213939217U. Although this type of device achieves hydroponics of strawberries, it still has obvious drawbacks in practical applications: 1. The liquid fertilizer in the planting basket remains stagnant for extended periods, which can lead to prolonged soaking of the strawberry roots, increasing the risk of root rot. Furthermore, the lack of regular root drying hinders the stimulation of the plants to develop robust aquatic root systems.

[0004] 2. Liquid fertilizer is prone to sedimentation in the bottom tank. If it is used directly without stirring, it will not only cause uneven nutrient supply, but may also cause blockage of the delivery pipeline, affecting the stable operation of the system.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] This invention provides a hydroponic strawberry cultivation device, such as... Figure 1-13 As shown, the hydroponic strawberry planting device includes: a bottom box 1 for holding liquid fertilizer required for hydroponic strawberry cultivation, the top of the bottom box 1 is provided with a feeding port 19 for adding liquid fertilizer, and a top cover 20 is threaded onto the feeding port 19; a rotating mounting cylinder 2 is located directly above the bottom box 1, the mounting cylinder 2 is provided with multiple mounting ports 21 for mounting multiple planting baskets 22 for planting strawberries, the planting baskets 22 are installed at an angle and are adapted to the mounting ports 21.

[0026] In this embodiment, a hydroponic strawberry cultivation device includes a base box 1 for holding liquid fertilizer required for hydroponic strawberry cultivation. The base box has a feeding port 19 and a threaded top cover 20 for easy addition of liquid fertilizer. A rotatable mounting cylinder 2, positioned directly above the base box 1, has multiple planting baskets 22 for planting strawberries installed at an angle through multiple mounting ports 21. This angled structure facilitates the extension of the strawberry plants and the hanging of the fruits. A drive mechanism periodically rotates the mounting cylinder 2, adjusting the orientation of the planting baskets 22 to ensure that all strawberry plants in the baskets receive uniform sunlight, thereby effectively improving photosynthetic efficiency, promoting uniform fruit coloring and sugar accumulation, and ultimately improving the overall yield and quality of the strawberries.

[0027] In a further preferred embodiment of the present invention, a cylindrical tube 10 is fixedly installed on the bottom box 1, and a cylindrical box 11 with an open top is rotatably installed inside the cylindrical tube 10 via a ring bearing. The mounting tube 2 is fixedly installed on the inner side wall of the cylindrical box 11 by multiple screws, and the inner side wall of the cylindrical box 11 is in complete contact with the outer wall of the mounting tube 2. The cylindrical tube 10 is equipped with a drive mechanism for driving the cylindrical box 11 to rotate, thereby driving the mounting tube 2 to rotate. By rotating the mounting tube 2 at a set angle, the planting baskets 22 in different positions on the mounting tube 2 are made to face the sunlight, so that all the strawberry seedlings in the planting baskets 22 have the opportunity to face the sunlight.

[0028] In this embodiment, a stable and highly coaxial rotating support body is formed. The drive mechanism mounted on the cylindrical tube 10 can reliably drive the cylindrical box 11 to rotate, thereby causing the mounting tube 2 and all the planting baskets 22 fixed thereto to rotate together. By setting the rotation program of the stepper motor 18 by the controller, the mounting tube 2 can be rotated periodically by a specific angle, thereby ensuring that the planting baskets 22 in different positions on the mounting tube 2 have the opportunity to face the sunlight, effectively solving the problem of uneven lighting caused by fixed orientation, so that the strawberry seedlings in all planting baskets 22 can get a balanced opportunity for photosynthesis, significantly improving the overall quality and uniformity of the strawberry fruit.

[0029] In a further preferred embodiment of the present invention, the driving mechanism includes a first mounting plate 14 fixedly mounted on one side of the cylindrical tube 10. A vertically arranged connecting shaft 15 is rotatably mounted on the first mounting plate 14 via a bearing. A spur gear 16 is fixedly sleeved at the bottom end of the connecting shaft 15. The spur gear 16 meshes with a ring gear 17 fixedly sleeved on the cylindrical box 11. A stepper motor 18 is fixedly mounted on the top of the first mounting plate 14. The output shaft of the stepper motor 18 is fixedly connected to the top end of the connecting shaft 15 via a coupling.

[0030] In this embodiment, the drive mechanism is stably supported by a first mounting plate 14 fixedly mounted on one side of the cylindrical tube 10. A vertical connecting shaft 15 rotatably mounted on the first mounting plate 14 via bearings ensures smooth transmission. A spur gear 16 at the bottom of the connecting shaft 15 meshes with a ring gear 17 fixedly sleeved on the cylindrical box 11 to form a transmission system for speed reduction and torque increase. A stepper motor 18 fixedly mounted on the top of the first mounting plate 14 is fixedly connected to the top of the connecting shaft 15 via a coupling to provide precise rotational power. When the stepper motor 18 starts according to the controller command, it drives the spur gear 16 to rotate through the connecting shaft 15, and the spur gear 16 drives... The ring gear 17 drives the cylindrical box 11 to rotate slowly under the support of the ring bearing. Then, through the screw connection, it drives the installation cylinder 2 and all the planting baskets 22 to rotate synchronously. This gear transmission method has the advantages of precise transmission and smooth operation. By precisely controlling the rotation angle of the stepper motor 18, the installation cylinder 2 can rotate at a fixed angle at set intervals, thereby ensuring that the planting baskets 22 in each position can obtain the best light position in turn. This solves the problem of light dead angle in traditional fixed cultivation, allows all strawberry plants to receive sunlight evenly, improves photosynthetic efficiency, and provides a reliable guarantee for the uniform growth and high yield and quality of strawberries.

[0031] In a further preferred embodiment of the present invention, the top of the bottom box 1 and the bottom of the cylindrical box 11 are both provided with the same annular raceway groove 12, and the annular raceway groove 12 is provided with a plurality of balls 13 that can roll within the annular raceway groove 12.

[0032] In this embodiment, the annular raceway grooves 12 corresponding to the top of the bottom box 1 and the bottom of the cylindrical box 11 together form a raceway, in which a plurality of balls 13 are arranged to form smooth rolling support within the annular raceway grooves 12; when the drive mechanism drives the cylindrical box 11 and the mounting cylinder 2 on it to rotate, the balls 13 roll efficiently between the upper and lower annular raceway grooves 12, transforming the traditional sliding friction into low-resistance rolling friction. This structure significantly reduces the frictional resistance and operating noise when the cylindrical box 11 rotates, enabling the stepper motor 18 to achieve smooth rotation with less driving force, while simultaneously supporting the cylindrical box 11 and the mounting cylinder 2.

[0033] In a further preferred embodiment of the present invention, a rubber sleeve 23 is fixedly fitted on the planting basket 22, the rubber sleeve 23 is in contact with the outer wall of the mounting cylinder 2, and a support plate 24 fixedly connected to the outer wall of the mounting cylinder 2 is provided below the rubber sleeve 23 for supporting the suspended strawberries.

[0034] In this embodiment, the rubber sleeve 23 fixedly fitted on the planting basket 22 fits tightly against the outer wall of the mounting cylinder 2, effectively achieving relative fixation between the planting basket 22 and the mounting cylinder 2. The support plate 24 fixedly connected to the outer wall of the mounting cylinder 2 below the rubber sleeve 23 provides reliable support for the strawberry fruits that grow from the planting basket 22 and hang naturally, preventing the fruit stems from breaking due to their own weight or excessive stretching of the plant. This design not only protects the complete growth of the fruit and reduces the rate of mechanical damage, but also makes the strawberry fruit shape more beautiful and regular. Combined with the rotation function of the mounting cylinder 2, it ensures that all suspended fruits can receive light evenly, further improving the quality and economic benefits of the strawberries.

[0035] In a further preferred embodiment of the present invention, the lower section of the planting basket 22 has no perforations, so that liquid fertilizer can be stored inside the planting basket 22, thereby allowing the strawberry seedling roots inside the planting basket 22 to extend into the liquid fertilizer; the planting basket 22 is provided with a liquid fertilizer inlet 25 for adding liquid fertilizer; the cylindrical tube 10 is equipped with a liquid fertilizer adding mechanism for adding liquid fertilizer into the planting basket 22, the liquid fertilizer adding mechanism including: a second mounting plate 30 fixedly installed on one side of the cylindrical tube 10, a liquid pump 31 fixedly installed at the bottom of the second mounting plate 30, and the inlet end and outlet end of the liquid pump 31 are respectively connected to an inlet pipe 32 and an outlet pipe 33. Pipe 34; a filter cartridge 33 installed at the bottom end of the liquid inlet pipe 32 and located inside the bottom box 1, the filter cartridge 33 prevents particulate matter from being sucked into the liquid inlet pipe 32; a central tube 35 set inside the mounting cylinder 2 and extending to the outside of the cylindrical box 11, the top end of the central tube 35 being sealed by an installed plug; a plurality of spray pipes 36 connected to the outer wall of the central tube 35 and all communicating with the central tube 35, the other end of the spray pipes 36 being equipped with a nozzle 37 for adding liquid fertilizer into the planting basket 22 through the liquid inlet 25; wherein, the bottom end of the central tube 35 is connected to one end of the liquid outlet pipe 34 via a telescopic rotating assembly and a liquid passing assembly.

[0036] In this embodiment, by setting the lower section of the planting basket 22 to a non-perforated structure, it can store liquid fertilizer, ensuring that part of the strawberry seedling roots can be directly immersed in the liquid fertilizer to absorb nutrients. The liquid inlet 25 on the planting basket 22 cooperates with the liquid fertilizer addition mechanism. This mechanism uses a liquid pump 31 fixed on the second mounting plate 30 on one side of the cylindrical tube 10 to draw liquid fertilizer from the bottom box 1 through the inlet pipe 32 with a filter cartridge 33. The filter cartridge 33 can effectively filter large particles of impurities to prevent pipe blockage. The liquid fertilizer is then transported through the outlet pipe 34, through the telescopic rotating assembly and the liquid conveying assembly to the central tube 35 in the mounting tube 2. Finally, it is injected into each planting basket 22 through the liquid inlet 25 by multiple spray pipes 36 and nozzles 37 connected to the central tube 35. At the same time, the telescopic rotating assembly ensures the continuity and sealing of the liquid fertilizer delivery during the rotation of the mounting tube 2, providing reliable nutritional support for the healthy growth of strawberries.

[0037] In a further preferred embodiment of the present invention, the telescopic rotating assembly includes: a telescopic tube 38 fixedly sleeved at the bottom end of the central shaft tube 35, and a rotating tube 39 fixedly connected to the bottom end of the telescopic tube 38; a first fixing plate 40 fixedly installed at the bottom of the cylindrical box 11, the first fixing plate 40 being fixedly connected to the rotating tube 39; and a connecting pipe 41 rotatably connected to the bottom end of the rotating tube 39 via a sealed bearing, a second fixing plate 42 fixedly connected to the connecting pipe 41, and the second fixing plate 42 being fixedly connected to the inner wall of the top of the bottom box 1.

[0038] In this embodiment, the telescopic rotating assembly realizes the axial extension and retraction freedom of the central shaft tube 35 through the telescopic tube 38 fixedly sleeved on the bottom end of the central shaft tube 35 and the rotating tube 39 fixedly connected to its bottom end; the rotating tube 39 achieves synchronous rotation through the first fixing plate 40 fixedly installed at the bottom of the cylindrical box 11, and its bottom end is rotatably connected to the connecting tube 41 through the sealing bearing, and the connecting tube 41 is fixedly connected to the top inner wall of the bottom box 1 through the second fixing plate 42; this ingenious design allows the central shaft tube 35 and its spray pipe 36 and nozzle 37 to rotate synchronously when the drive mechanism drives the cylindrical box 11 and the mounting cylinder 2 to rotate. At the same time, the extension and retraction characteristics of the telescopic tube 38 are coordinated with the lifting and lowering of the central shaft tube 35, while the sealing bearing ensures the dynamic sealing at the connection between the rotating tube 39 and the connecting tube 41, preventing liquid fertilizer leakage. Thus, while realizing the all-round rotation adjustment of the mounting cylinder 2 to adjust the light, it ensures that the liquid fertilizer adding mechanism continuously and stably delivers liquid fertilizer to each planting basket 22.

[0039] In a further preferred embodiment of the present invention, the liquid transfer assembly includes a cylindrical box 43. The top of the cylindrical box 43 is fixedly connected to the bottom of the second fixed plate 42 by a plurality of fixing rods 46. The side wall of the cylindrical box 43 is provided with a liquid inlet 44 and a liquid outlet 45. The liquid inlet 44 is fixedly connected to one end of the liquid outlet pipe 34, and the liquid outlet 45 is fixedly connected to one end of the connecting pipe 41. A linkage stirring assembly is installed on the cylindrical box 43.

[0040] In this embodiment, the liquid transfer assembly is kept stationary by being fixed to the bottom of the second fixed plate 42 via multiple fixed rods 46 at the top of its cylindrical box 43. The liquid inlet 44 on the side wall of the cylindrical box 43 is fixedly connected to the liquid outlet pipe 34 to introduce liquid fertilizer, while the liquid outlet 45 is fixedly connected to the connecting pipe 41 to output liquid fertilizer. A stable fluid transfer station is established between the liquid pump 31 and the rotating mounting cylinder 2, ensuring the continuity and sealing reliability of the liquid fertilizer transmission between the static pipeline and the dynamic rotating component. At the same time, the linkage stirring assembly installed on the cylindrical box 43 converts the kinetic energy of the liquid fertilizer flow into mechanical stirring power. When the liquid fertilizer flows through the cylindrical box 43, it drives the linkage stirring assembly to run, thereby continuously stirring the liquid fertilizer in the bottom tank 1. This integrated design achieves anti-sedimentation treatment of liquid fertilizer without additional power, ensuring nutrient uniformity and effectively preventing pipeline blockage.

[0041] In another embodiment of the present invention, the linkage stirring assembly includes: a vertical shaft 50 rotatably mounted inside a cylindrical box 43 via a sealed bearing and vertically arranged, with one section of the vertical shaft 50 extending below the cylindrical box 43; a connecting sleeve 53 fixedly sleeved on the vertical shaft 50, on which multiple water impellers 54 are fixedly installed, both the connecting sleeve 53 and the water impellers 54 being located inside the cylindrical box 43; and a horizontal rod 51 fixedly sleeved on the vertical shaft 50, on which multiple vertically arranged stirring rods 52 are fixedly installed. By driving the water impellers 54 to rotate through the liquid fertilizer inside the cylindrical box 43, the horizontal rod 51 and the stirring rods 52 thereon are ultimately driven to rotate, thus stirring the liquid fertilizer in the bottom tank 1 to prevent sedimentation and blockage of the pipes.

[0042] In this embodiment, the linkage stirring assembly transmits power through a vertical shaft 50 rotatably mounted inside a cylindrical box 43 via a sealed bearing. A connecting sleeve 53 is fixedly fitted onto the upper part of the vertical shaft 50 within the cylindrical box 43. Multiple water turbine blades 54 mounted on the connecting sleeve 53 rotate due to fluid impact as the liquid fertilizer flows through the cylindrical box 43. A horizontal bar 51 is fixedly mounted below the cylindrical box 43 at the lower end of the vertical shaft 50. Multiple vertical stirring rods 52 mounted on the horizontal bar 51 rotate synchronously with it. This design cleverly converts the fluid kinetic energy during the liquid fertilizer transport process into mechanical energy. Yes, when the liquid pump 31 supplies liquid fertilizer to the planting basket 22, the liquid fertilizer flowing through the cylindrical box 43 automatically drives the water wheel blade 54 to rotate the vertical shaft 50, which in turn continuously stirs the liquid fertilizer in the bottom box 1 through the crossbar 51 and the stirring rod 52. This stirring method, which does not require additional power, effectively prevents the precipitation of solid particles in the liquid fertilizer, ensuring the uniformity of nutrient distribution and avoiding the clogging of components such as the filter cartridge 33, the liquid inlet pipe 32, and the nozzle 37 by sediment, thereby improving the stability and reliability of the entire liquid fertilizer supply system and reducing the maintenance frequency and operating costs.

[0043] In a further preferred embodiment of the present invention, the bottom of the planting basket 22 is provided with a drainage hole for draining water and fertilizer from the planting basket 22, allowing the strawberry seedlings to dry their roots to prevent root rot and promote the growth of aquatic roots. The central tube 35 is equipped with multiple sealing components, including an installation rod 60 fixedly installed on the outer wall of the central tube 35. The other end of the installation rod 60 is detachably fitted with a sealing plug 61, which is located inside the planting basket 22 and seals the drainage hole.

[0044] In this embodiment, by setting a drainage hole at the bottom of the planting basket 22 and using a sealing component installed on the central tube 35, scientific management of the strawberry root system is achieved. The sealing component consists of an installation rod 60 fixed to the outer wall of the central tube 35 and a sealing plug 61 that can be detachably installed at its end. Under normal conditions, the sealing plug 61 tightly seals the drainage hole of the planting basket 22, allowing the planting basket 22 to store an appropriate amount of liquid fertilizer for the strawberry roots to absorb. When the roots need to be dried, the sealing plug 61 is removed from the drainage hole by lifting the central tube 35, and the liquid fertilizer accumulated in the planting basket 22 can be discharged smoothly. This periodic drainage process can effectively avoid long-term soaking of the roots, reduce the risk of root rot, and at the same time, the alternating wet and dry environment stimulates the growth of aquatic roots, thereby enhancing the plant's nutrient absorption capacity, improving the strawberry's growth vitality and disease resistance, and achieving a breakthrough in root health management from passive control to active prevention.

[0045] In another embodiment of the present invention, a top plate 62 is fixedly installed at the top end of the mounting cylinder 2. A lifting assembly is provided on the top plate 62 for raising the central tube 35 so that the sealing plug 61 rises and disengages from the drainage hole of the planting basket 22, thereby allowing the water and fertilizer in the planting basket 22 to be discharged through the drainage hole for root drying. The lifting assembly includes: a fixing frame 63 fixedly installed at the bottom of the top plate 62, with two vertically arranged limiting rods 64 fixedly held inside the fixing frame 63; and a lifting plate 65 fixedly sleeved on the central tube 35, the lifting plate 65 sliding sleeve An electric push rod 67 is fixedly installed on the inner wall of the bottom of the fixed frame 63, and is provided on two limiting rods 64. When the output rod is extended, it contacts the bottom of the lifting plate 65 and pushes the lifting plate 65 upward to provide the driving force for the sealing plug 61 to move upward. A compression spring 66 is installed between the top of the lifting plate 65 and the bottom of the top plate 62. When the output rod of the electric push rod 67 is retracted to its shortest position, the compression spring 66 exerts a downward force on the lifting plate 65, causing the sealing plug 61 to press against the drainage hole of the planting basket 22 to seal it, so that the planting basket 22 can store water and fertilizer.

[0046] In this embodiment, the top plate 62 fixedly installed at the top of the mounting cylinder 2 and the lifting assembly thereon together constitute the root drying control mechanism. Two vertically arranged limiting rods 64 inside the fixed frame 63 provide stable vertical guidance for the lifting plate 65 fixedly sleeved on the central tube 35, ensuring no deflection during its lifting process. Upon receiving a controller command, the electric push rod 67 fixed to the inner wall of the bottom of the fixed frame 63 extends its output rod to lift the lifting plate 65, thereby pushing the central tube 35 upwards as a whole, causing the sealing plug 61 to rise synchronously and disengage from the drainage hole of the planting basket 22, thus achieving smooth drainage of the liquid fertilizer. When the electric push rod 67... When rod 67 retracts, the compression spring 66 installed between the top of lifting plate 65 and the bottom of top plate 62 provides a continuous downward elastic force, driving lifting plate 65, along with central tube 35 and sealing plug 61, to reset, ensuring that sealing plug 61 re-tightens the drainage hole and restores the sealing state. This automated lifting component realizes the precise and controllable circulation of liquid storage and drainage in planting basket 22. By programmably controlling the start and stop of electric push rod 67, it can simulate the root environment of alternating dry and wet conditions under natural conditions, which not only effectively prevents the occurrence of root rot, but also significantly promotes the development of strawberry aquatic roots, thereby improving the plant's nutrient absorption efficiency and overall health level.

[0047] In a further preferred embodiment of the present invention, a photovoltaic power generation module 70 is installed on the top of the top plate 62, and a battery mounting bracket 71 is fixedly installed on the bottom of the bottom box 1, and a lithium battery 72 is provided thereon. The photovoltaic power generation module 70 uses sunlight to generate electricity to charge the lithium battery 72, thereby providing power to the electrical equipment. The connection method between the lithium battery 72, the photovoltaic power generation module 70, and the electrical equipment is a mature existing technology and is well known to those skilled in the art, and will not be described in detail here.

[0048] In this embodiment, a complete energy self-sufficiency system is constructed by installing a photovoltaic power generation module 70 on the top of the top plate 62 and setting a lithium battery 72 at the bottom of the base box 1 via a battery mounting bracket 71. The photovoltaic power generation module 70 efficiently converts solar energy into electrical energy during the day and stores it in the lithium battery 72. This electrical energy stably powers core electrical equipment such as the stepper motor 18, liquid pump 31, and electric actuator 67. Simultaneously, the device is also equipped with a charging port for charging the lithium battery 72 during prolonged cloudy or rainy weather. This is easily implemented by those skilled in the art and will not be elaborated upon here.

[0049] In a further preferred embodiment of the present invention, a liquid level sensor 8 is installed on the bottom tank 1 to monitor the liquid fertilizer level inside the bottom tank 1.

[0050] In this embodiment, by installing a liquid level sensor 8 on the bottom tank 1, real-time monitoring of the liquid fertilizer level in the bottom tank 1 is realized. The liquid level sensor 8 continuously feeds back the liquid level data to the controller. When the liquid fertilizer level is lower than the set threshold, an alarm can be automatically triggered to ensure that the liquid fertilizer in the bottom tank 1 can be replenished in time, effectively avoiding the situation of insufficient liquid fertilizer.

[0051] It is worth noting that the circuits, electronic components, and modules involved in this invention are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this invention does not involve improvements to the software and methods. This solution also includes a controller, which is installed on the equipment. During use, the controller can automatically start the operation of each electrical device. The power connection method of each electrical device is a mature existing technology and is well known to those skilled in the art, so it will not be described in detail here. The control circuit of the controller can be implemented by those skilled in the art through simple programming.

[0052] In summary, compared with related technologies, the hydroponic strawberry cultivation device provided by this invention, through its rotatable mounting cylinder 2 and planting basket 22 design, coupled with a precisely controlled drive mechanism, effectively solves the core problem of uneven light exposure for strawberry plants in traditional fixed cultivation, thereby improving photosynthetic efficiency and fruit quality. Its innovative liquid fertilizer addition and automatic root drying system, through the synergistic action of the sealing plug 61 and the lifting component, achieves periodic irrigation and drainage of liquid fertilizer within the planting basket 22, preventing root rot and promoting the development of aquatic roots. Simultaneously, the linked stirring component utilizes the kinetic energy of the liquid fertilizer flow to automatically prevent sedimentation, ensuring uniform nutrient supply.
