[0039] The present invention provides a three-dimensional trapezoidal green planting device, which has the following advantages compared with the prior art:

[0040] 1. The device of the present invention is ingenious and has two major advantages: space utilization and multi-functional integration. On the one hand, the trapezoidal structure is used to cleverly improve the utilization efficiency of land space and maximize the planting benefits in a limited area; on the other hand, the functions of electric drive, supplementary lighting, and water replenishment are integrated, and intelligent automatic control is achieved through technical means. In this planting mode, the planting process such as lighting duration and humidity adjustment does not require frequent manual operation, which significantly reduces labor costs. This model has revolutionized the traditional planting method and improved efficiency and sustainability. Based on nutrient blocks and covered with homemade organic soil, soil fertility can be guaranteed without fertilization, and hydroponics is carried out on both sides of the machine, thereby realizing the diversification of planting methods. The three-dimensional trapezoidal green planting device of the present invention has significant advantages, and has the characteristics of energy saving and environmental protection, and reduces floor space. It can effectively improve the growth efficiency of plants and optimize planting results, and has good practical value and application prospects.

[0041] 2. Equipped with an advanced controller, using PLC control technology, it can receive and analyze the data transmitted by temperature sensors, humidity sensors, and light sensors in real time, accurately adjust the rotation duration of the device, the opening time of the supplementary lighting device, and the startup of the water replenishment device to meet the needs of different growth stages of plants.

[0042] 3. The supplementary lighting device is equipped with wire solar panels, which generate electricity when there is sufficient sunlight, and are powered by wires on cloudy days. The battery stores the electricity converted from solar energy during the day for the supplementary lighting device, reducing power consumption. Only one set of supplementary lighting device and water replenishment device are equipped. By rotating the device, it can fully cover all planting columns in all directions, ensuring uniform distribution of light and water, avoiding waste of resources, and achieving efficient utilization of water resources. The soil in the planting columns uses organic matter, without chemical substances such as chemical fertilizers, pesticides, and herbicides, reducing environmental pollution and ensuring food safety.

[0043] 4. The nutrient block is made of a mixture of seaweed powders, which has a wide source and is beneficial to resource recycling and environmental protection.

Detailed implementation manners

[0054] To make the technical problems solved by the present invention, the technical solutions adopted and the achieved technical effects clearer, the present invention will be further described in detail below with reference to the drawings and embodiments.

[0055] As Figures 1-3 shown, a three-dimensional trapezoidal green planting device provided by an embodiment of the present invention includes a base 4, a support frame 1, a motor 9, a plurality of rotating shafts 22 and two chains 17.

[0056] On both sides of the base 4, support frames 1 are respectively fixed; the base 4 and the support frames 1 on both sides form a fixed support device, providing a solid support foundation for the entire device. The base 4 is provided with feet.

A plurality of walking wheels 5 are installed below the base 4, making the device easy to move. Fixing bolts 2 are precisely installed on the upper and lower sides of the support frame 1, and these fixing bolts 2 can effectively suppress the vibration generated by the rotating shaft 22 during operation. Through the action of the fixing bolts 2, the device can maintain stable operation.

[0057] A plurality of rotating shafts 22 are arranged between two support frames 1; a motor 9 is arranged on one of the support frames 1; the motor 9 is in transmission connection with one of the rotating shafts 22; gears 15 are equipped at both ends of each rotating shaft 22; the gears 15 on each side are meshed with a chain 17; a plurality of fixed connectors 18 are symmetrically arranged on the two chains 17; a planting column 16 is fixed on each pair of fixed connectors 18. Specifically, as Figure 4 shown, connecting plates 20 are respectively arranged at both ends of the planting column 16, and the connecting plates 20 are connected with the corresponding fixed connectors 18. Gears 15 are assembled on the rotating shafts 22, and the gears 15 are tightly meshed with the chains 17, forming a reliable transmission system. The chains 17 are connected with the fixed connectors 18, ensuring the stability of the transmission structure. The planting column 16 is firmly fixed through the connecting plates 20 and the fixed connectors 18, providing a safe carrier for plant cultivation. The motor 6 is the power core of the device, responsible for driving the whole machine to operate stably; the motor 6 is used to drive the normal operation of the gears 15 for the convenience of work, and the chains 17 drive the operation of the planting column 16.

[0058] A water replenishing device 12 and a light supplementing device 13 are arranged in the space between the two support frames 1; specifically, as Figure 6 shown, two central shafts 19 are installed between the two support frames 1; the water replenishing device 12 is suspended below one central shaft 19 through a suspension rod 14, and the light supplementing device 13 is suspended below the other central shaft 19. Sleeves can be arranged on the central shafts 19 to fix the suspension rods 14. The light supplementing device 13 is equipped with electric wire solar panels, which generate electricity when the sun is sufficient, and are powered by electric wires on cloudy days, saving power resources; the storage battery 6 stores the electricity converted from solar energy during the day and supplies power to the light supplementing device 13. It can be replenished with electricity through electric wires on rainy and cloudy days to ensure the normal use of the light supplementing device 13. There is a lampshade at the upper end of the light supplementing device 13 to prevent water from entering and damaging the lamp tubes. The light supplementing device 13 is connected with the solar panels and the storage battery 6. The solar panels are arranged outside, and the storage battery 6 is arranged on the side of the support frame 1. The pipes of the water replenishing device 12 use plastic pipes or rubber pipes.

[0059] Hydroponic trays 10 are arranged on the outer sides of each support frame 1. The hydroponic trays 10 are connected with a water pump through water pipes 8. Specifically, as Figure 5 shown, water culture tray bottoms 21 and fixed support plates 11 are respectively arranged at both ends of the hydroponic trays 10; the inner fixed support plates 11 are connected with the support frames 1. The present invention is equipped with two hydroponic trays 10 on the outer sides of the two support frames 1. Only water source, nutrient blocks and organic matter soil are needed for plant cultivation. Water resources are input into the hydroponic trays 10 through the water pump 8, and the operation is simple, which is suitable for cultivating some plant varieties suitable for hydroponics.

[0060] The planting device of the present invention is in a three-dimensional trapezoidal shape, with both sides in a staircase shape. In terms of lighting design, compared with traditional vertically-up-and-down planting equipment, the present invention has a trapezoidal structure, which cleverly solves the problem of light occlusion. Whether the sun rises or sets, plants can be fully bathed in sunlight, greatly extending the photosynthesis duration of the planted crops. The plants can efficiently absorb light energy continuously from morning to night, solving the problem of plant phototropism. The top area of the device is spacious, which provides more lighting space for the planted crops, facilitating their robust growth and enhancing photosynthetic efficiency. The present invention effectively avoids the drawback that the upper layer blocks the lower layer and affects sunlight absorption; enables plants to fully receive sunlight from morning to night, extends the photosynthesis duration, has a large top area, provides more lighting space for the planted crops, allows the plants to efficiently carry out photosynthesis at any time, and improves photosynthetic efficiency.

[0061] The planting device of the present invention adopts a reasonable planning of the machine size, with a length of 490 CM, a width of 150 CM, and a height of 455 CM. While meeting the planting requirements, it greatly saves the floor area and reduces the input of site costs. For example, 53 machines can be installed in a 716-square-meter greenhouse, and the economic benefits are remarkable. The compact and reasonable size planning greatly saves the floor area and reduces the input of site costs while meeting the planting requirements. First, convert the units of the length and width of the bottom rectangle of the equipment from centimeters to meters. Since 1 meter = 100 centimeters, 490 centimeters is converted to 4.9 meters after conversion, and 150 centimeters is converted to 1.5 meters after conversion. The calculation is as follows:

[0062] S 面积 =a 长 xb 宽

[0063] 4.9x1.5=7.35

[0064] The present invention saves capital costs, further reduces the floor area, and with the improvement of planting efficiency, the yield of the planted crops increases accordingly, and the economic benefits are quite considerable. In addition, due to the rotation design, with a set of water replenishing device 12 and light supplementing device 13, all planting columns can be covered comprehensively, ensuring the uniform distribution of light and water, avoiding the dispersion and waste of resources, reducing unnecessary power consumption, and achieving the dual goals of energy conservation and environmental protection, which has great practical value and popularization significance.

[0065] In the three-dimensional trapezoidal green planting device of the present invention, a temperature sensor, a humidity sensor, a light sensor, a controller 3 and a storage battery 6 are arranged on one of the support frames 1; the temperature sensor, the humidity sensor and the light sensor are respectively electrically connected to the controller 3; the controller 3 is electrically connected to the motor 9. Specifically, the motor 6 and the controller 3 are installed on different support frames 1, and the layout design on both sides of the support frame 1 aims to optimize the space utilization.

[0066] The controller 3 includes: The controller 3 is electrically connected to the motor 9, the water replenishing device 12, and the light supplementing device 13 respectively. The controller 3 adopts advanced PLC technology and can collect the data of temperature sensors, humidity sensors, and light sensors in real time. Through data collection, processing, and recording, the controller 3 can conveniently adjust the rotation duration of the motor 9, the light supplementing device 13, and the water replenishing device 12, which can improve the growth efficiency of the planted crops. The controller 3 can flexibly and accurately adjust the rotation duration of the motor 6 and the opening timing of the light supplementing device 13. It can also start the water replenishing device 12 in a timely manner according to the change of environmental humidity to meet the needs of the plants at different growth stages. The device of the present invention can be applied in a greenhouse where the temperature change is small, judged according to the constant temperature in the greenhouse; the indoor temperature can be collected by a temperature sensor and can be connected to a display device for display. The specific control process is as follows:

[0067] In this embodiment, the control process of the motor 9:

[0068] For the growth periods of different crops, in the seedling stage, the crops are relatively weak and require light and water in a certain pattern. At this time, less light is needed, and the rotation period of the equipment should be set longer. At this time, regardless of the weather, the daytime working mode is set to rotate one circle per hour. At the same time, on the basis of supplementing light and water, create a mild and stable growth environment for the seedlings.

[0069] During the growth process, during this period, the plants need a large amount of light and water. It is necessary to shorten the rotation time. During this period, regardless of the weather, set the rotation speed to rotate once every forty minutes, and turn on both the light supplementing device 13 and the water supplementing device 12 to allow all parts of the plant to receive sufficient light and water, accelerating photosynthesis and metabolism to meet the substances and energy required for its rapid growth.

[0070] In the mature period, the growth rate of the plants slows down, and the demand for light and water also tends to be stable. The rotation cycle can be adjusted to rotate once per hour, reducing the supplementary light and supplementary water, reasonably controlling the supply of light and water, preventing the plants from growing too vigorously, which is beneficial to the nutrient accumulation of the plants and improves the quality.

[0071] In summary:

[0072] 1. In the seedling stage of the crops, set the rotation cycle of the motor 9 during the day to rotate one circle per hour;

[0073] 2. In the growth stage of the crops, set the rotation cycle of the motor 9 during the day to rotate one circle every forty minutes;

[0074] 3. In the mature stage of the crops, set the rotation cycle of the motor 9 during the day to rotate one circle per hour;

[0075] During the seedling stage, growth stage, and maturity stage of crops, set the rotation period of the night motor 9 to one revolution per hour, and the running time to 4 hours.

[0076] In this embodiment, the control process of the supplementary lighting device 13:

[0077] First, through the investigation of vegetables, it is found that the light intensity that ordinary vegetables can absorb is between 5000 - 15000 lux. Therefore, we can set corresponding thresholds according to the lighting requirements of different plants during the growth process.

[0078] During the seedling stage, its requirement for light intensity is relatively small. We can set 5000 lux as the minimum illuminance threshold for turning on the supplementary light. If the light intensity is less than this threshold, the photosynthetic efficiency of the plants will be significantly reduced, unable to meet the growth needs of the seedlings. At this time, it is necessary to control the automatic opening of the supplementary lighting device 13. When the lighting intensity exceeds 12000 lux, the upper limit threshold for turning off the supplementary lighting device 13 can be set to 12000 lux. This is because continuously increasing the light intensity will not improve the photosynthesis effect of vegetables much, and it will also cause damage such as light inhibition to the seedlings.

[0079] To ensure the light supply during the growth stage of vegetables and increase their light demand, adjust its minimum light intensity threshold to 7000 lux to ensure the normal growth of crops. When the light intensity is higher than 15000 lux, the upper limit threshold for turning off the supplementary lighting device 13 is set to 15000 lux to avoid damage to the plants caused by excessive light.

[0080] During the maturity stage of vegetables, the lighting requirements change. The lower limit threshold for turning on the supplementary lighting device 13 can be set to 6000 lux, which helps the development of fruits and the accumulation of sugars. The upper limit threshold for turning off the supplementary lighting device 13 is set to 13000 lux, which can prevent excessive light from affecting the fruit quality while ensuring the light required for fruit growth.

[0081] When the light intensity is lower than the set lower limit threshold, the controller 3 automatically turns on the supplementary lighting device 13 to supplement light for the plants; when the light intensity is higher than the upper limit threshold, the controller 3 turns off the supplementary lighting device 13 to prevent damage to the plants caused by excessive light. The data of the light sensor can be combined with the data of the temperature sensor, humidity sensor, etc. to comprehensively judge the plant growth environment.

[0082] In summary:

[0083] 1. During the seedling stage of crops, during the day, when the light intensity is lower than 5000 lux, turn on the supplementary lighting device 13; when the light intensity is higher than 12000 lux, turn off the supplementary lighting device 13;

[0084] 2. During the growth stage of the crops, during the day, when the light intensity is lower than 7000 lux, turn on the supplementary lighting device 13; when the light intensity is higher than 12000 lux, turn off the supplementary lighting device 13;

[0085] 3. During the maturity stage of the crops, during the day, when the light intensity is lower than 6000 lux, turn on the supplementary lighting device 13; when the light intensity is higher than 13000 lux, turn off the supplementary lighting device 13;

[0086] During the seedling stage, growth stage, and maturity stage of the crops, at night, the operating time of the supplementary lighting device 13 is 3 hours after nightfall.

[0087] In this embodiment, the control process of the water supply device 12:

[0088] According to the water requirements of different plant growth periods, set the corresponding humidity thresholds. When the suitable humidity for the seedling stage is 70% - 80%, when starting the water supply equipment, the lowest humidity threshold can be set to 70%; as the plants grow, in the maturity stage, the suitable humidity range can be adjusted to 60% - 70%.

[0089] The humidity sensor monitors the air humidity in the greenhouse in real time and transmits it to the controller 3, and the controller 3 processes these data. When the humidity is lower than the set lowest humidity threshold, automatically turn on the water supply equipment 12 to supply water to the plants; when the humidity exceeds the highest humidity threshold, automatically cut off the water supply equipment 12 to avoid diseases caused by excessive humidity. At the same time, analyze the data collected by the humidity sensor.

[0090] When the light intensity is high, the plants need a large amount of water. At this time, if the humidity is very low, the water supply can be increased; in the case of insufficient light, the water demand of the plants decreases, and the high humidity condition can be appropriately extended.

[0091] In this embodiment, after running at night, to turn off the three-dimensional trapezoidal green planting device, the following steps can be taken:

[0092] According to the investigation, turning on the lights at night in the greenhouse can promote plant growth, slow down the consumption of plant organic matter by respiration, and enable the plants to grow rapidly. However, when using the supplementary lighting device 13, it should also be noted that the supplementary lighting device 13 cannot be used for 12 hours throughout the night. Supplementary lighting can be carried out within 3 hours after 18:00 at night, and then the lights should be turned off to give the plants a rest time, otherwise it will also cause the death of the plants.

[0093] First, reduce the rotation period of the device. Set the rotation period to one revolution per hour and set the device to stop running after 4 hours. After stopping, in the PLC, stop the control program of motor 9 to cut off the power supply of motor 9 and stop the drive device from running to avoid unnecessary energy consumption. Then, set the shutdown time for the supplementary lighting device 13 to turn it off after a certain time to prevent continuous operation and waste of electric energy. The water replenishing device 12 usually includes a water pump, water pipes, etc. Operate on the control interface to turn off the water pump and temporarily disable the humidity sensor data acquisition in the system to ensure that the water replenishing device stops running. Finally, after turning off the device, check whether each component stops running normally, check whether the planting column 16 returns to its position, and whether there is abnormal vibration or heating of any component. If any problem is found, record it in time and troubleshoot the fault. Regularly clean the device, such as cleaning the dust on the lampshade of the supplementary lighting device 13, dredging the blockage of the water pipes of the water replenishing device 12, checking the wear of motor 9 and transmission components, etc., to ensure the normal operation of the device next time and extend its service life.

[0094] Taking advantage of the above advantages, this equipment breaks through the seasonal restrictions and can cultivate crops in different seasons, providing strong support for realizing diversified year-round planting.

[0095] The nutrient blocks added in the planting column 16 are formed by extruding a powder mixture of cattle and sheep manure, straw and seaweed through a nutrient block pressing device and then processed by heating and sterilization. They have various shapes and the pressing plate molds can be replaced according to requirements.

[0096] On the basis of the above solution, the three-dimensional trapezoidal green planting device of the present invention is equipped with a nutrient block pressing device. As Figure 7As shown, the nutrient block briquetting device includes: an oil cylinder 23, a box body 24, a high-pressure oil pipe 25, an oil tank 26, a briquetting machine motor 27, a box body door 28, a safety lock 29, and a pressing plate mold 30. When the nutrient block briquetting device operates, the briquetting machine motor 27 and the gear pump start, suck oil from the oil tank 26, and the oil enters the oil cylinder 23 through the high-pressure oil pipe 25, and the oil cylinder 23 provides the extrusion force. According to different types of pressing plate molds 30, the powder in the box body 24 is extruded and formed. After forming, open the box body door 28, and the formed nutrient block can be taken out. The working principle is as follows: First, prepare the raw materials. The powder used by the nutrient block briquetting device is composed of cattle and sheep manure, straw, and seaweed. These raw materials are widely sourced and are beneficial to resource recycling and environmental protection. First, mix these raw materials evenly to make a powder material suitable for processing. Then, for extrusion and forming, operate the briquetting machine motor 27 to generate power to drive the equipment to operate. Under the action of pressure, the powder is extruded through a specific pressing plate mold 30. Since the shape of the pressing plate mold 30 can be replaced, various shapes of nutrient blocks can be molded to meet different planting requirements, such as the adaptability requirements of different plant varieties for the shape of the nutrient block. Finally, for sterilization treatment: The formed nutrient block needs to be sterilized by means of a heating device. This step can effectively kill harmful microorganisms, bacteria, etc. in the nutrient block, avoid their adverse effects on plant growth during subsequent plant planting, ensure that plants grow in a healthy environment, and finally obtain a finished nutrient block for planting use.

[0097] The production of nutrient blocks is achieved by operating the briquetting machine motor 27 to quickly extrude and form the powder through the pressing plate mold 30. After placing the nutrient block on the planting column 16, directly lay organic soil on it to provide the nutrients required for plant growth. When the nutrient content of the nutrient block gradually decreases, only spraying nutrient solution can restore its nutrients, eliminating the need for fertilization, thereby reducing damage to plants and achieving green environmental protection. Moreover, the pressing plate mold 30 can be replaced with different shapes to meet different needs. Using the nutrient block briquetting device to quickly press the powder into blocks effectively saves time.

[0098] The nutrient blocks placed on the planting column 16 are formed by extruding the powder through the nutrient block briquetting device and then undergoing heating and sterilization treatment. They have various shapes and the pressing plate mold 30 can be replaced according to needs. The powder is made from seaweed, which is not only beneficial to resource recycling but also plays a positive role in environmental protection. Its production process is to first use the nutrient block briquetting device for extrusion and forming. Different shapes can be molded due to different pressing plate molds 30 used. After forming, it is then sterilized by means of a heating device to finally obtain the finished product.

[0099] When the present invention is used for planting, the formed nutrient blocks are placed in the planting column 16. After adding organic soil into the nutrient blocks, the planting operation is carried out. When the nutrient loss occurs in the nutrient blocks after half a year, nutrient solution is sprayed to restore the nutrients, so as to continuously support the growth of plants and ensure the normal growth of plants. The nutrient solution contains calcium nitrate tetrahydrate, potassium nitrate, potassium dihydrogen phosphate, and magnesium sulfate heptahydrate, reducing the damage of fertilization to plants and realizing green and environment-friendly planting.

[0100] The soil in the planting column 16 of the present device uses organic matter, without chemical substances such as chemical fertilizers, pesticides, and herbicides. It consists of 10% additives, 60% organic matter, and 30% minerals. The 10% additives are biological bacteria agents, the 60% organic matter is seaweed residues, and the 30% minerals are perlite. It has the advantages of recycling residual substances to protect the environment and can supplement nutrients without using chemical fertilizers, thus achieving green organic matter planting. Specifically, a shredder is used to stir the seaweeds into fragments, and then the 10% additives, 60% organic matter, and 30% minerals are mixed together. The 10% additives are biological bacteria agents, the 60% organic matter is seaweed residues, and the 30% minerals are perlite. The additives and organic matter can increase the soil fertility, and the minerals can increase the soil stability, achieving the goal of not using chemical fertilizers, being green and environment-friendly, and making people feel more at ease when eating.

[0101] Aiming at the disadvantages of the traditional planting method, the three-dimensional trapezoidal green planting device of the present invention is innovated in terms of structural design, function realization, planting mode, and data management. By using advanced PLC control technology and combining humidity and light, it accurately adjusts the operation of the device to meet the needs of different growth stages of plants and realizes automatic management. The supplementary lighting device uses solar panels and storage batteries, which is energy-saving and environment-friendly; the unique trapezoidal structure solves the problem of light occlusion, improves the photosynthetic efficiency, and the device has a reasonable size design, saving land space; the planting method combining nutrient blocks and organic matter soil reduces the use of chemical fertilizers and pesticides and ensures food safety; the hydroponic column is easy to operate and meets the planting needs of different plants. The nutrient block pressing device can produce nutrient blocks with various shapes, further enriching the planting options; the device has the functions of data collection, processing, and recording, providing data support for optimizing the planting process and improving the yield and quality, helping to deeply study the growth law of plants, promoting the innovation of planting technology. The device has remarkable effects in improving land utilization rate, reducing costs, and enhancing planting benefits, meets the development needs of modern facility agriculture, has good practical value and popularization significance, and is expected to promote the development of agricultural planting towards the direction of intelligence and greenness.
