Description

Technical Field

[0001] The invention relates to the technical field of soilless vegetable cultivation, in particular to an agricultural soilless vegetable cultivation device. Background Art

[0002] Soilless vegetable cultivation refers to a new type of cultivation method that does not use natural soil, but uses substrates (such as rock wool, coconut bran, vermiculite, etc.), water or other media as growth carriers for plant roots, and uses artificially prepared nutrient solutions to provide vegetables with the moisture, nutrients, oxygen and other conditions required for growth. In a soilless cultivation system, vegetable roots are in direct contact with the nutrient solution, or grow in a substrate rich in nutrient solution, which can absorb nutrients and water more efficiently, thereby promoting vegetable growth. This cultivation method is free from the constraints of soil, and can flexibly adjust the nutrient solution formula and environmental conditions according to the needs of different growth stages of vegetables, so as to achieve high-quality, high-yield and efficient production of vegetables.

[0003] Vegetables grown without soil need to be observed regularly to prevent plant nutrition imbalance, root diseases, water shortage or excessive light. Existing agricultural soilless vegetable cultivation generally uses manual regular observation and adjustment of the growth environment to ensure the normal growth of the plants. However, due to the high density of agricultural planting, on the one hand, manual observation is difficult and the large number of observations makes the adjustment of the cultivation device time-consuming, and it is easy for manual observation to affect the growth process of the plants, which is not conducive to the growth of the plants. On the other hand, there is a lag in manual observation of the plants, which makes it impossible for the growth environment of some plants to be adjusted in time and damaged. Therefore, it is necessary to develop an agricultural soilless vegetable cultivation device that is easy to observe the growth status of plants and can be adjusted in time. Summary of the invention

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0045] See also Figure 1 and Figure 2 , which shows a schematic structural diagram of an agricultural soilless vegetable cultivation device provided in an embodiment of the present application, wherein the cultivation device includes a cultivation box 100, a carrier frame 200, an observation mechanism 300, a nutrient supply mechanism 400 and a control console.

[0046] Specifically, the cultivation box 100 is provided with a cultivation cavity 110, and the same type of plants with the same required growth environment are cultivated in the cultivation cavity 110 of the same cultivation box 100, so that each cultivation box 100 can provide the same type of plants with the appropriate lighting conditions and nutritional adjustments, reduce interference from other types of plants, and also facilitate management. The top of the cultivation box 100 is provided with a light receiving port 120 connected to the cultivation cavity 110, and the light receiving port 120 is connected to the outside world, so as to introduce natural light into the cultivation cavity 110, provide the required lighting conditions for the plants, and promote the healthy growth of the plants.

[0047] The support frame 200 is arranged in the cultivation chamber 110, and a plurality of plant cultivation plates 210 and a driving mechanism 220 are arranged on the support frame 200; the plurality of plant cultivation plates 210 are slidably connected to the support frame 200 in sequence, so that the plant cultivation plates can change their positions on the support frame 200 so as to be more fully exposed to sunlight, improve photosynthesis efficiency, and promote plant growth and development. Improve photosynthesis efficiency and promote plant growth and development. Preferably, the plant cultivation plates 210 are arranged at intervals from each other, and the driving mechanism 220 is drivingly connected to the multiple plant cultivation plates 210. The driving mechanism 220 is used to drive the plant cultivation plates 210 to cyclically pass through the lighting area 230, the observation area 240 and the nutrition supplement area 250 on the carrier 200. The continuously moving plant cultivation plates overcome the characteristics of insufficient plant light and difficulty in observation faced by dense planting, greatly improving the space utilization rate of the cultivation chamber 110, and the automated circulation design reduces the workload of moving plants during manual observation, reduces labor costs, and makes the entire cultivation process efficient and convenient.

[0048] The nutrient supply mechanism 400 is arranged in the nutrient supplement area 250, and the nutrient supply mechanism 400 is used to provide a nutrient mixture to the plants passing through the nutrient supplement area 250; the driving mechanism 220, the observation mechanism 300 and the nutrient supply mechanism 400 are respectively electrically connected to the control console, and the control console is used to receive image information and to control the nutrient supply mechanism 400 to adjust the concentration of the nutrient mixture.

[0049] The use process of the agricultural soilless vegetable cultivation device provided in the embodiment of the present application is as follows:

[0050] Before the equipment is started, the operator first precisely controls the first flow control valve 421 and the second flow control valve 431 through the console. According to the preset proportional parameters, the console sends instructions to the first flow control valve 421 and the second flow control valve 431 to make them work together to precisely mix the nutrient solution output by the nutrient solution supplier 420 and the water output by the water source supplier 430 in the supply tank 410, thereby preparing a nutrient mixture that meets the needs of the plant's specific growth stage.

[0051] Next, the operator places the soilless vegetable plants in order on the plant cultivation plates 210 on the carrier 200 to ensure that the plants are stable and in a suitable cultivation position. After the plants are placed, the operator again issues a command to the drive mechanism 220 through the console to start the drive mechanism 220. The drive mechanism 220 then drives the plant cultivation plates 210 to start a circular motion according to the preset program, passing through the illumination area 230, the observation area 240 and the nutrition supplement area 250 in turn.

[0052] When the plant cultivation plate 210 moves to the observation area 240, the observation equipment installed in the observation area 240 captures real-time image information of each plant passing by, and sends it to the control console through wired or wireless transmission. The control console processes the received image information and presents it clearly to the observer. The observer carefully observes these images to analyze and judge whether the plant has abnormal growth conditions such as malnutrition and water shortage. Once the observer finds that the plant has the above problems, the nutrient supply mechanism 400 and the drive mechanism 220 can be adjusted through the control console. On the one hand, the control console sends instructions to the nutrient supply mechanism 400 to adjust the mixing ratio of the nutrient mixture, thereby changing the concentration of the nutrient mixture to meet the plant's demand for nutrients and improve the nutritional supplement effect on the plant; on the other hand, the control console regulates the speed of the drive mechanism 220, and by increasing or decreasing the residence time of a single plant cultivation plate 210 in the nutritional supplement area 250, the precise control of the plant's nutrient absorption is achieved, ensuring that the plant can grow healthily in a suitable environment.

[0053] The beneficial effects of the agricultural soilless vegetable cultivation device provided in the embodiment of the present application are as follows:

[0054] On the one hand, the movable plant cultivation plate 210 enables the plants to be in a suitable environment at different growth stages. By moving between the various areas, it is ensured that the plants make full use of the light resources, meet the photosynthesis requirements, and provide sufficient energy for growth. At the same time, it also enables the observation of all plants to be completed at one angle, which helps to detect the growth of the plants in a timely manner and improves the convenience of observation. On the other hand, the observation equipment in the observation area 240 captures image information in real time and transmits it to the control console, which facilitates the observers to timely detect the nutrition, water and pest problems of the plants, thereby ensuring the health of the plants. The observers can also change the concentration of the nutrient mixture through the control console according to the actual situation, adjust the speed of the driving mechanism 220, flexibly control the length of time the plants stay in the nutrient supplement area 250, realize the precise regulation of nutrient absorption, and improve the efficiency of nutrient utilization. In addition, the entire operation is completed by relying on the control console, which greatly reduces the tedious manual work and reduces the labor intensity. At the same time, the driving mechanism 220 drives the cultivation plate to circulate, realizes automated and efficient cultivation management, and significantly improves production efficiency.

[0055] Preferably, if Figure 3 As shown, the nutrient supply mechanism 400 provided in the present application includes a supply tank 410 , a nutrient solution supplier 420 and a water source supplier 430 .

[0056] Specifically, the supply tank 410 is arranged at the bottom of the support frame 200, and the output end of the nutrient solution supplier 420 is located in the supply tank 410 to facilitate the direct delivery of the nutrient solution to the supply tank 410 for use. The nutrient solution supplier 420 is provided with a first flow control valve 421 to control the flow of the nutrient solution; the output end of the water source supplier 430 is located in the supply tank 410 so that the nutrient solution and water can be quickly mixed. The water source supplier 430 is provided with a second flow control valve 431, and the second flow valve is used to control the flow of water. The first flow control valve 421 and the second flow control valve 431 are respectively electrically connected to the control console.

[0057] When the console receives the flow control parameters input by the operator, it will send the command to the first flow control valve 421 and the second flow control valve 431. The nutrient solution supplier 420 delivers the nutrient solution of the corresponding flow rate to the supply tank 410 according to the command received by the first flow control valve 421. At the same time, the water source supplier 430 also injects an appropriate amount of water into the supply tank 410 under the control of the second flow control valve 431; the first flow control valve 421 and the second flow control valve 431 accurately adjust the flow of the nutrient solution and water so that the two are mixed in the supply tank 410 according to a preset ratio. In this process, the nutrient solution and water continuously flow into the supply tank 410 to mix and form a new nutrient mixture. Preferably, the nutrient supply mechanism 400 can also be provided with a stirring mechanism (not shown in the figure) to make the nutrient solution and water more fully mixed, improve the uniform distribution of the nutrient solution, ensure that there is no obvious deviation in the nutrient absorption of the plant roots, and help the healthy growth of the plant.

[0058] Plant roots grow in the nutrient solution and require sufficient oxygen for respiration to maintain normal metabolism. Preferably, the nutrient supply mechanism 400 also includes an oxygen supplier 440, which can be a small air pump or a bubble generator. The output port of the oxygen supplier 440 is located in the supply tank 410. The oxygen supplier 440 can ensure that there is enough dissolved oxygen in the nutrient solution, promote the absorption of nutrients by the roots, prevent the roots from rotting due to lack of oxygen, and improve the survival rate and yield of the plants; the oxygen supplier 440 is electrically connected to the console, and the operator can input instructions in the console according to the real-time state of plant growth and various monitoring data, and then adjust the operating state of the oxygen supplier 440. Whether it is the flow rate of oxygen output or the time interval of supply, precise control can be achieved. For example, during the high temperature period in summer, the respiration of plant roots is enhanced and the demand for oxygen increases. At this time, the oxygen output flow of the oxygen supplier 440 is increased through the control console to ensure that the plant roots obtain sufficient oxygen, effectively maintain a high dissolved oxygen content in the nutrient solution, ensure normal respiratory and metabolic activities of the roots, promote healthy root growth, and enable plants to better absorb nutrients from the nutrient solution, laying a solid foundation for the healthy growth of the plants.

[0059] See also Figure 4A mounting groove 260 is provided on the carrier 200, and the mounting groove 260 is ring-shaped. The driving mechanism 220 includes a first motor 221, a first synchronous belt 222, a plurality of sliders 223 and a plurality of plug shafts. The first motor 221 is electrically connected to the control console to receive control instructions from the control console; the output end of the first motor 221 is drivingly connected to the first synchronous belt 222, the first synchronous belt 222 is wound in the mounting groove 260, and the first synchronous belt 222 is slidably connected to the mounting groove 260, and a plurality of sliders 223 are sequentially arranged on the first synchronous belt 222 at intervals, and each slider 223 is respectively rotatably connected to one end of the plurality of plug shafts in a one-to-one correspondence, and the other end of each plug shaft is respectively rotatably connected to the plant cultivation plate 210 in a one-to-one correspondence. During the operation of the entire system, the driving motor drives the first synchronous belt 222 to rotate around the installation groove 260 in the installation groove 260, thereby driving the slider 223 to rotate cyclically. The slider 223 transmits power to the plant cultivation plate 210 through the plug shaft, so that the plant cultivation plate 210 circulates on the carrier 200 and passes through the illumination area 230, the observation area 240 and the nutrition supplement area 250 in sequence. At the same time, due to the sliding connection relationship between the plug shaft and the plant cultivation plate 210, the plant cultivation plate 210 can maintain its own balance and is not easy to tip over during the movement of the slider 223. It can be understood that the driving mechanism 220 can also be a chain transmission driving mechanism 220 or a ring track roller driving mechanism 220.

[0060] See also Figure 5a and Figure 5b The agricultural soilless vegetable cultivation device also includes a light transmission control mechanism 130, which is installed at the light receiving port 120. The light transmission control mechanism 130 is electrically connected to the control console to receive control instructions from the control console to control the amount of light supplemented by the natural light source.

[0061] Preferably, the light transmission control mechanism 130 includes a second motor, a second synchronous belt, a plurality of driven wheels and a plurality of shading plates 131, and the second motor is electrically connected to the control console; when in use, the operator sets the parameters on the control console according to the light requirements of plant growth, and when the light intensity needs to be adjusted, the operator modifies the parameters and sends a control command to the second motor, and the second motor starts after receiving the command, and its output end rotates to drive the second synchronous belt connected to it to operate, and the second synchronous belt transmits power to the driven wheel, so that the driven wheel rotates, thereby driving the shading plates 131 connected to it to rotate, thereby realizing the precise regulation of the amount of supplementary light from the natural light source to meet the light intensity requirements of plants at different growth stages. For example, when it is necessary to reduce light intensity, the shading plate 131 rotates to reduce the light channel between two adjacent shading plates 131, thereby reducing the entry of light.

[0062] It can be understood that the light transmission control mechanism 130 can also be a liquid crystal dimming glass control mechanism. Liquid crystal dimming glass is a material that combines a liquid crystal film between two layers of glass and controls the arrangement direction of liquid crystal molecules by applying an electric field, thereby achieving changes in the light transmittance of the glass. When no electric field is applied, the liquid crystal molecules are arranged in disorder, the light is scattered in the liquid crystal layer, and the glass is opaque; when the electric field is applied, the liquid crystal molecules are arranged in order along the direction of the electric field, the light can pass smoothly, and the glass becomes transparent. Install it at the light receiving port 120, and control the electric field intensity applied to the liquid crystal dimming glass through the console to achieve precise adjustment of the light amount.

[0063] Preferably, the cultivation box 100 is also provided with a plurality of fill lights 140, which are arranged at intervals in sequence at the light receiving port 120 and are located in the cultivation cavity 110. When natural light is insufficient, the fill lights 140 can supplement the light for the plants in the cultivation cavity 110 to provide a stable light source for the cultivation box 100, thereby ensuring uninterrupted photosynthesis of the plants, maintaining the growth rhythm, and avoiding problems such as slow growth and poor development due to lack of light. At the same time, the fill lights 140 can more flexibly adjust the duration and intensity of light to meet the growth needs of different plants and improve the yield and quality of soilless cultivation.

[0064] See also Figure 6a and Figure 6b Preferably, the plant cultivation plate 210 is provided with a plurality of planting tubes 211, the top of the planting tubes 211 is provided with an opening, and the side walls of the planting tubes 211 are provided with a plurality of air holes 212 to ensure smooth air circulation and provide sufficient oxygen supply for the plant roots; the bottom of the planting tubes 211 is provided with a plurality of drainage holes 213 to ensure that excess water can be discharged in time to prevent the roots from rotting due to water accumulation. The planting tubes 211 are used to place plants; the plant cultivation plate 210 is provided with a plurality of planting through holes 214, and the plurality of planting through holes 214 are arranged in sequence and spaced apart, and the openings of each planting tube 211 are axially connected to the plurality of planting through holes 214 in a one-to-one correspondence, respectively, to provide an independent and suitable growth environment for the plants, avoid mutual interference between the plants, facilitate the individual management and observation of the plants, and also help to improve the growth efficiency and quality of the plants.

[0065] As the plants grow, the weight distribution on the plant cultivation board 210 may change due to factors such as differences in plant growth and nutrient solution adhesion. Once the weight is unevenly distributed, it is easy to cause the cultivation board to tilt or even tip over, which will not only cause physical damage to plant growth, but may also affect the normal operation of the entire soilless cultivation system. Preferably, the plant cultivation board 210 is also provided with a balance adjustment block 215, which can balance the weight borne by the cultivation board by adjusting its own position or weight, ensuring that the cultivation board is always in a stable horizontal state, effectively ensuring the stability and reliability of the soilless cultivation process, reducing the losses caused by the tipping of the cultivation board, and providing a solid foundation for the thriving growth of plants.

[0066] See also Figure 6c and Figure 6d In the agricultural soilless vegetable cultivation device provided in another embodiment of the present application, the plant cultivation plate 210 and the planting tube 211 are detachably connected, the planting tube 211 is plugged into the planting through hole 214, and an anti-falling ring is provided on the top. As the plant grows, impurities may accumulate and bacteria may breed in the planting tube 211. The detachable connection method allows the operator to easily remove the planting tube 211 for thorough cleaning and disinfection, thereby creating a cleaner growth environment for the plant roots and reducing the probability of disease and insect pests. At the same time, when part of the planting tube 211 is damaged, there is no need to replace the entire plant cultivation plate 210, only the damaged planting tube 211 needs to be replaced, which greatly saves costs. In addition, since different plants have different requirements for growth space and specifications of the planting tube 211, the detachably connected planting tube 211 allows the operator to easily replace the planting tube 211 of different sizes and structures according to the plant species and growth stage to meet the diverse growth needs of the plants, thereby optimizing the plant growth environment and improving cultivation efficiency and plant yield.
