Technical Field

[0001] The invention relates to the technical field of agricultural cultivation, in particular to a multifunctional three-dimensional cultivation system. Background Art

[0002] In the existing agricultural cultivation technology, traditional planting methods such as substrate cultivation, soil cultivation and hydroponics each have their own advantages and limitations. For example, soil cultivation is suitable for a variety of plants, but it is easily affected by environmental factors such as soil quality, pests and diseases; hydroponics can avoid soil problems and promote faster plant growth, but it requires high equipment and technical investment. In addition, most of the existing cultivation equipment is specifically designed for a certain cultivation method, and it is difficult to flexibly adapt to the needs of different crops, causing growers to need to replace equipment or make additional investments when switching between multiple cultivation modes. In addition, existing seedling equipment is often used separately from the cultivation system, which not only increases the cost of equipment procurement and operation, but also limits the efficient integration of seedling cultivation and cultivation processes. In the hydroponic system, the irradiation of plant growth lights can cause the growth of green algae, affect the quality of the nutrient solution, and increase maintenance costs, but most current hydroponic systems do not provide effective solutions to avoid the growth of green algae.

[0003] Therefore, the existing technology has the technical bottlenecks of single cultivation mode, high equipment investment, inefficient integration of cultivation and seedling raising process, and failure to effectively solve the problem of green algae growth in hydroponic system. Therefore, those skilled in the art have proposed a multifunctional three-dimensional cultivation system to solve the above problems. Summary of the invention

When cleaning the substrate or soil culture system, the movable surface buckle plate can be opened for cleaning. In the hydroponic mode, the movable surface buckle plate is always kept in a closed state, and the nutrient solution inside the liquid storage tank is sprayed out through the water spray port outside the liquid spray pipe by starting the pump body, and the opening and closing of the overflow port are coordinated to form two sets of planting systems.

[0010] Preferably, an electronic valve is installed on the outside of the spray pipe, and a liquid level meter is installed inside the planting rack. The liquid level meter is used for detection. When the set water level is reached, the electronic valve opens the nutrient solution to flow into the next planting trough. When multiple planting troughs reach the set height of the nutrient solution, the liquid supply is automatically stopped.

The outer surface of the cover plate is detachably connected with a valve. The cover plate and the valve are used to cover the nutrient solution in the planting trough during hydroponics for plant planting, to prevent the nutrient solution from turning green when exposed to light, affecting the appearance and consuming the nutrients in the nutrient solution. During substrate culture and hydroponics, the cover plate is removed and the spray system is turned on for irrigation of water and fertilizer. After the plants are harvested, when cleaning is required, the movable surface buckle plate is opened to clean the planting trough.

[0014] The present invention provides a multifunctional three-dimensional cultivation system. It has the following beneficial effects: 1. The present invention can simultaneously support different cultivation modes such as substrate culture, hydroponics and soil culture by designing a multifunctional cultivation trough, thereby realizing an integrated solution to multiple needs of different crop cultivation. This compatibility greatly improves the versatility of the equipment and reduces the investment cost of growers. Growers can freely choose the appropriate cultivation method according to the needs or growth cycles of different crops, thereby improving the flexibility and efficiency of production. In addition, the present invention integrates the seedling raising and cultivation processes into the same cultivation trough through the design of a hydroponic cover plate that can be used for both seedling raising and growth, thereby reducing the demand for additional seedling raising equipment and reducing equipment procurement and operating costs. In addition, the six-petal openable and closable valve design on the hydroponic cover plate can effectively avoid the growth of green algae caused by direct radiation from plant growth lamps, thereby reducing the waste and pollution of nutrient solution caused by green algae. Its self-adhesive design allows the diaphragm to be replaced regularly, ensuring high efficiency and hygiene in long-term use, while saving the cost of frequent replacement of the cover plate.

[0015] 2. The present invention adopts an adjustable plant growth lamp lifting mode, which can automatically adjust the light intensity and irradiation range according to the growth stage of the plant, ensuring that the plants can obtain the most suitable lighting conditions at each growth stage. At the same time, combined with the automatic control of the electronic valve and the liquid level meter, the system can avoid excessive liquid supply or overflow while ensuring sufficient supply of water and fertilizer, thereby saving water resources and improving the utilization efficiency of fertilizers.

[0016] 3. The present invention is designed with an adjustable height of the cultivation rack, which can flexibly adjust the height of the cultivation trough according to the growth characteristics and needs of different crops. This function is particularly suitable for planting crops of various sizes and growth cycles, ensuring that the crop roots can fully contact the nutrient solution. At the same time, the present invention can reciprocate the spray pipe to ensure that the water or nutrient solution is evenly covered in all parts of the cultivation area. Through the repeated swinging of the water flow, the water droplets can be more widely distributed around the root system of the plant, avoiding the problem of excessive or insufficient irrigation in some areas caused by a single fixed nozzle.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions 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 of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Please refer to the attached Figure 1 -Attached Figure 8The embodiment of the present invention provides a multifunctional three-dimensional cultivation system, including a liquid storage tank 1, two fixed frames 2 are fixedly connected to the left and right sides of the top of the liquid storage tank 1, a pump body 18 is installed on the inner side of the liquid storage tank 1, the input end of the pump body 18 is fixedly connected to the second connecting pipe 20, the output end of the pump body 18 is fixedly connected to the first connecting pipe 8, the outer side of the first connecting pipe 8 is connected to the spray pipe 11 through a plurality of connectors 10, the outer side of the spray pipe 11 is connected to a plurality of water spray ports, a plurality of planting frames 3 are installed on the inner side of the fixed frame 2, a plurality of planting grooves 12 are opened on the outer surface of the planting frame 3, and the planting grooves 12 are used for planting crops, The bottom of the planting trough 12 is connected to an overflow port 13, and a movable buckle plate 14 is arranged inside the overflow port 13. The movable buckle plate 14 is in a closed state in the working state to prevent excess water from overflowing. When the movable buckle plate 14 is lifted upward, the overflow port 13 can be automatically opened to discharge excess water. When cleaning the substrate or soil culture system, the movable buckle plate 14 can be opened for cleaning. In the hydroponic mode, the movable buckle plate 14 always remains in a closed state, and the nutrient solution in the liquid storage tank 1 is sprayed out through the water spray port outside the spray pipe 11 by starting the pump body 18, and the opening and closing of the overflow port 13 are coordinated to form two planting systems.

[0021] Specifically, the movable surface buckle plate 14 inside each layer of planting trough 12 is moved downward until the movable surface buckle plate 14 blocks the overflow port 13. Start the pump body 18 to transport the nutrient solution in the liquid storage tank 1 to each spray pipe 11 through the second connecting pipe 20 and the first connecting pipe 8. The electronic valve 9 of the first layer will automatically open to allow the nutrient solution to enter the first layer of planting racks 3. When the liquid level meter 4 on the inside of the first layer of planting racks 3 detects the set water level, the electronic valve 9 of the first layer will automatically close. As the electronic valve 9 of the first layer closes, the electronic valve 9 of the second layer automatically opens to start supplying liquid to the second layer. This process is repeated in sequence, and when the liquid level meter 4 of each layer detects the set water level, the corresponding electronic valve 9 is closed, and then the electronic valve 9 of the next layer is opened. When all planting racks 3 have reached the set nutrient solution height, all electronic valves 9 will automatically close, and the system stops supplying liquid. The left and right sides of the top of the planting frame 3 are fixedly connected with the second electric telescopic rod 5, the output end of one of the second electric telescopic rods 5 is rotatably mounted with a support frame 601, the top of the support frame 601 is provided with a mounting cavity 606, the interior of the mounting cavity 606 is slidably connected with a rack plate 603, the outer side of the support frame 601 is mounted with a first electric telescopic rod 602, the top of the other second electric telescopic rod 5 is rotatably connected with a mounting plate 605, and one side of the mounting plate 605 is fixedly connected with a driving gear 604. The driving gear 604 is mounted on the top of the support frame 601, the outer side of the driving gear 604 is meshed and connected with the outer side of the rack plate 603, and the driving end of the first electric telescopic rod 602 is fixedly connected with one end of the rack plate 603.

[0022] Specifically, after the second electric telescopic rod 5 is started, the support frame 601 and the mounting plate 605 move in the vertical direction. This can control the up and down position of the spraying equipment to ensure that different areas are evenly supplied with nutrients. When the first electric telescopic rod 602 is started, it drives the rack plate 603 to slide along the inner wall of the mounting cavity 606. The movement of the rack plate 603 causes the driving gear 604 to swing forward and backward, thereby driving the mounting plate 605 to swing left and right, further expanding the spraying range. Due to the meshing of the driving gear 604 and the rack plate 603, the sliding of the rack plate 603 enables the liquid spraying device to swing left and right and move up and down synchronously, thereby achieving precise control of the area and range of the liquid spraying.

[0023] The device uses the second electric telescopic rod 5 and the first electric telescopic rod 602 in cooperation, so that the spraying device can flexibly adjust the spraying range and angle, avoiding the problem of uneven irrigation that may be caused by a single fixed nozzle. The water droplets cover the surrounding of the plant roots through repeated swinging, ensuring that the water or nutrient solution can be evenly distributed to all parts of the cultivation area.

[0024] The outer side of the fixing frame 2 is slidably connected with a slider 706, the inner side of the slider 706 is fixedly connected with a connecting plate 701, the interior of the connecting plate 701 is provided with a mounting groove 703, the inner wall of the mounting groove 703 is provided with a limiting groove 704, the outer through hole of the connecting plate 701 is threadedly connected with a driving screw 702, one side of the driving screw 702 is rotatably connected with a fixing plate, the outer side of the fixing plate is rotatably connected with two connecting rods 708, one end of the connecting rod 708 is rotatably connected with a clamping column 705, and the interior of the slider 706 is provided with a clamping groove 707. The longitudinal section of the clamping column 705 is set to be square, and one end of the clamping column 705 is plugged into and matched with the interior of the clamping groove 707.

[0025] Specifically, by rotating the driving screw 702, the fixed disk starts to rotate. The rotation of the fixed disk will drive one end of the external connecting rod 708 to swing. The swing of the connecting rod 708 can generate traction through its structural design. The traction force of the connecting rod 708 causes the clamping column 705 to move along the inner wall of the limiting groove 704 in the connecting plate 701. Since one end of the clamping column 705 cooperates with the clamping groove 707, the clamping column 705 will gradually disengage from one end of the clamping groove 707 during this process, causing the slider 706 to move along the outer surface of the fixed frame 2. The height adjustment of the planting rack 3 can be achieved by the movement of the slider 706. After adjusting to the appropriate height, the operation can be stopped. When the adjustment is completed, the movement direction of the fixed disk, the connecting rod 708 and other components is reversed by rotating the driving screw 702 in the opposite direction, and the clamping column 705 is reinserted into the clamping groove 707 to fix the slider 706, so that the planting rack 3 is restored to a fixed state. The square longitudinal section of the clamping column 705 is closely matched with the internal structure of the clamping slot 707, ensuring that the slider 706 operates stably during the adjustment process. The limit slot 704 ensures that the clamping column 705 can only move in one direction, preventing it from deviating from the designed trajectory, and providing a precise adjustment function. An electronic valve 9 is installed on the outside of the spray pipe 11, and a liquid level meter 4 is installed inside the planting rack 3. The liquid level meter 4 is used for detection. When the set water level is reached, the electronic valve 9 opens the nutrient solution to flow into the next planting trough 12. When multiple planting troughs 12 reach the set height of the nutrient solution, the liquid supply is automatically stopped. In the hydroponic mode, the liquid level meter 4 and the electronic valve 9 work together to ensure that the liquid flow does not affect the position and function of the cover 15 and the valve 16.

[0026] Specifically, the liquid level meter 4 is installed inside the planting rack 3, and is mainly used to detect the water level of the nutrient solution in each planting trough 12 in real time. When the liquid level in a certain layer of planting troughs 12 reaches the preset water level, the liquid level meter 4 will send a signal to the electronic valve 9 to trigger it to open, thereby allowing the nutrient solution to flow into the lower planting trough 12, ensuring that the nutrient solution can be evenly supplied to the plants on each layer. This design effectively avoids the situation of uneven supply or excessive inflow of nutrient solution, and ensures the healthy growth of plants. When the liquid levels of multiple planting troughs 12 reach the set water level, the liquid level meter 4 will continue to monitor the changes in the liquid levels of each layer, and after the water levels of all planting troughs 12 reach the predetermined standard, it will automatically send a closing signal to the electronic valve 9 to stop the inflow of nutrient solution. This automatic liquid stop function not only effectively saves the use of nutrient solution and avoids waste, but also ensures the efficient operation of the entire cultivation system.

[0027] The inside of the liquid storage tank 1 is detachably connected with a filter screen 19, and the inside of the liquid storage tank 1 is fixedly connected with a plurality of immersion sterilization lamps 21, which are used to disinfect the germs in the nutrient solution. Several planting lamps 17 are installed at the bottom of the mounting plate 605, and the spray pipe 11 is fixedly connected to the bottom of the mounting plate 605. The inner wall of the planting trough 12 is equipped with a cover plate 15, and a bend is set in the middle of the planting trough 12 for placing the cover plate 15. The outer surface of the cover plate 15 is detachably connected with a valve 16. The cover plate 15 and the valve 16 are used to cover the nutrient solution in the planting trough 12 during hydroponics, and are used for plant planting to prevent the nutrient solution from turning green in the light, affecting the appearance and consuming the nutrients in the nutrient solution. When substrate culture and hydroponics are carried out, the cover plate 15 is removed, the spray system is turned on, and water and fertilizer are irrigated. After the plants are harvested, when cleaning is required, the movable surface buckle plate 14 is opened to clean the planting trough 12.

[0028] Specifically, the liquid storage tank 1 is a container for storing and providing nutrient solution. In order to ensure that the nutrient solution is clean and not contaminated by impurities, a detachable filter 19 is arranged inside the liquid storage tank 1, which can be regularly disassembled and cleaned to prevent impurities from entering the nutrient solution. Inside the liquid storage tank 1, a plurality of immersion sterilization lamps 21 are arranged. These sterilization lamps are designed to be directly immersed in the nutrient solution, and their purpose is to kill the germs and microorganisms in the nutrient solution, ensure the cleanliness and health of the hydroponic environment, reduce the risk of bacterial infection, and ensure the healthy growth of plants. The mounting plate 605 is a fixed platform, and a plurality of planting lamps 17 are fixedly connected to its bottom. These lamps provide the light required by the plants, which helps the photosynthesis and growth of the plants.

[0029] The cover plate 15 can be used for both hydroponics and growth. The row spacing of the planting holes is set according to the row spacing of the crop seedling stage. After the seedlings grow up, thinning can be carried out, and the seedlings are retained according to the row spacing during the crop growth period, and the thinned seedlings are moved into other planting grooves 12. During the process of seedling thinning and moving in, the valve 16 on the cover plate 15 opens and closes with the process of pulling out and inserting. In the process of pulling out the seedlings, the valve 16 on the planting plate is closed by force, and in the process of planting, the valve 16 on the planting plate is opened by force to form a closure, so as to prevent the light source from directly irradiating the nutrient solution, forming green algae, and consuming nutrients in the nutrient solution; the valve 16 is a self-adhesive valve 16, which can be replaced regularly or according to the degree of use.

[0030] Working principle: S1: Preparation First, prepare the nutrient solution or aqueous solution suitable for plant growth and place it in the liquid storage tank 1. An immersion sterilization lamp 21 is installed in the liquid storage tank 1 to disinfect the germs in the nutrient solution to ensure the hygiene and safety of the liquid. The pump body 18 in the liquid storage tank 1 connects and drives the two circulation planting systems to transport the nutrient solution to each planting tank through the pipeline.

[0031] S2: Hydroponic mode In the hydroponic mode, the movable surface gusset plate 14 of each layer of planting trough 12 is in a closed state to ensure that the overflow port 13 is not blocked. At this time, the liquid level meter 4 starts to work and monitors the water level. Start the pump body 18, and the nutrient solution is transported to each spray pipe 11 through the second connecting pipe 20 and the first connecting pipe 8. When the first-layer liquid level meter 4 detects the set water level, the first-layer electronic valve 9 is closed and the second-layer electronic valve 9 is automatically opened. In this way, each planting rack 3 stops supplying liquid at the set water level. When the water level of all planting racks 3 reaches the set height, all electronic valves 9 will be closed, and the system will automatically stop supplying liquid.

[0032] S3: Soil culture and substrate culture mode Adjustment of the active face gusset plate 14: Under the soil culture and substrate culture modes, in order to carry out root irrigation and cleaning work, the active face gusset plate 14 needs to be opened. At this time, the active face gusset plate 14 is in an open state, which is convenient for cleaning and drainage.

[0033] Control of the spray device: During soil culture or substrate culture, the open state of the movable surface buckle plate 14 cooperates with the spray system. The spray pipe 11 sprays the nutrient solution evenly to the planting area. The first electric telescopic rod 602 and the second electric telescopic rod 5 drive the swing of the spray device through the rack plate 603 and the driving gear 604 to ensure the uniform distribution of water or nutrient solution and avoid excessive or insufficient irrigation in some areas caused by fixed nozzles. The overflow port 13 is used to collect excess nutrient solution to prevent water accumulation. The overflow port 13 discharges excess nutrient solution to ensure that the liquid supply in the system is quantitative and stable. In the soil culture and substrate culture modes, the liquid level meter 4 does not participate in the liquid level monitoring, so the electronic valve 9 will not be affected by the liquid level changes.

[0034] Function of the overflow port 13: Different from the overflow port 13 in the hydroponic mode, the overflow port 13 in the soil culture and substrate culture modes is mainly used to remove excess nutrient solution or water to prevent excessive water loss, but does not rely on the control of the liquid level meter 4. The overflow port 13 recovers excess nutrient solution and guides it back to the liquid storage tank for reuse.

[0035] S4: Cover and valve working mode Cover and valve design: In hydroponic mode, a bend is set at 7 cm in the middle of each planting trough 12 for placing the cover 15. An appropriate nutrient solution height is set below the cover 15 to ensure that the plant roots can fully contact the nutrient solution, while maintaining a distance between the leaf surface and the cover to facilitate the breathing of the roots. A valve 16 is installed on the cover 15, and as the seedlings are moved in or pulled out, the valve 16 will automatically open and close according to the force. When pulling out the seedlings, the valve 16 is closed under the action of force; when planting the seedlings, the valve 16 will open with force to ensure that the nutrient solution is not exposed to light, avoid the formation of green algae, and ensure that the nutrients in the nutrient solution will not be consumed.

[0036] S5: Height adjustment of planting rack 3 By rotating the driving screw 702, the fixing plate can drive the connecting rod 708 to swing, thereby realizing the movement of the clamping column 705, and then controlling the height adjustment of the planting rack 3. After the adjustment is completed, by rotating the driving screw 702 in the opposite direction, one end of the clamping column 705 is clamped into the clamping groove 707 to ensure that the planting rack 3 is fixed at the correct height position. The height adjustment function of the planting rack 3 ensures that each layer of the planting groove 12 can maintain a suitable height according to the growth needs of different plants, ensuring sufficient supply of water and nutrients.

[0037] S6: Water recovery and nutrient solution management In soil culture and substrate culture modes, the overflow port 13 is used to recover excess nutrient solution to prevent excessive water loss. The recovered nutrient solution is transported back to the liquid storage tank 1 through a pipeline for reuse to maintain the recycling of the liquid. When the nutrient solution in the system reaches a certain use cycle, the liquid storage tank 1 can be manually emptied to replace new nutrient solution. This operation can be performed through manual adjustment or system prompts to ensure that the quality of the nutrient solution in the system always meets the growth requirements of plants.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
