Description

Technical Field

[0001] This invention relates to the field of facility vegetable horticulture technology, specifically to a dynamic response facility for vegetable cultivation. Background Technology

[0002] Currently, vegetable cultivation facilities (such as greenhouses, plastic tunnels, and plant factories) are widely used in agricultural production, providing crops with a controllable growth environment, effectively resisting adverse weather conditions, and increasing yields. However, the structural design of existing facilities is usually static, making it impossible to dynamically adjust the height of the space according to the crop's growth needs, leading to the following problems:

[0003] 1. Unable to adapt to the needs of crops at different growth stages

[0004] Seedling stage: The plants are small and require less space. However, the existing fixed-height facilities have too large an internal space, which leads to increased air circulation, reduced temperature and humidity control efficiency, and increased energy consumption (such as the need to handle a larger volume of air for heating in winter or cooling in summer).

[0005] Maturity stage: For vining crops such as tomatoes and cucumbers, plant height increases significantly, but fixed-height facilities may restrict the extension of stems and leaves, leading to overcrowding, poor ventilation, and increased risk of pests and diseases.

[0006] 2. Inaccurate light management

[0007] In facilities that use artificial lighting (such as plant factories or multi-layer cultivation systems), the light source (such as LEDs) is usually fixed in place. As the plant grows taller, the top leaves may get too close to the light source, causing photoscalding or photoinhibition, while the middle and lower leaves may be shaded and receive insufficient light, affecting the overall photosynthetic efficiency.

[0008] In natural light greenhouses, the fixed height of the roof cannot be adjusted according to the solar altitude angle, which may cause some crops to be damaged by ultraviolet rays during the strong sunlight period in summer, or insufficient light in winter due to the low angle of light incidence. Summary of the Invention

[0009] To address the technical problems existing in the background art, this invention proposes a dynamic response facility for vegetable cultivation.

[0010] The present invention proposes a dynamic response facility for vegetable cultivation, comprising: a frame, a lifting rod, a roof, and a curtain roll;

[0011] The enclosure is made up of multiple panels joined end to end, and is used to enclose the outer perimeter of the vegetable growing area;

[0012] The lifting rods are installed vertically on the enclosure frame, and there are multiple lifting rods arranged at circumferential intervals along the enclosure frame.

[0013] The canopy is set above the enclosure and supported by lifting rods;

[0014] The curtain roll includes a core tube and a curtain wound on the core tube; there are multiple curtain rolls arranged sequentially along the circumference of the frame, and the core tube of each curtain roll is rotatably installed on the frame, and the free end of the curtain of each curtain roll is connected to the ceiling.

[0015] Preferably, the curtain is made of a light-transmitting film and is divided into multiple light-transmitting zones along its length, with each zone having a different light transmittance; the ceiling has multiple rotatable rollers installed around its circumference, and the free ends of each curtain are wound onto the corresponding rollers.

[0016] Preferably, it further includes a first drive mechanism for driving the core cylinder to rotate and a second drive mechanism for driving the drum to rotate.

[0017] Preferably, the curtain roll is divided into inner and outer layers, wherein there is a corresponding outer curtain roll on the outside of any two adjacent curtain rolls in the inner layer, and the curtain of the outer curtain roll overlaps with the curtains in the two adjacent curtain rolls in the inner layer.

[0018] Preferably, the overlapping areas of the outer and inner curtains are connected to each other by connecting accessories.

[0019] Preferably, the connecting accessories include a soft magnetic adsorption strip made of soft magnetic material and a flexible strip containing magnetic material; the soft magnetic adsorption strip is disposed on the inner side of the outer curtain along the length direction of the outer curtain; the flexible strip is disposed on the outer side of the inner curtain along the length direction of the inner curtain.

[0020] Preferably, the connecting accessories include the fleece side of the hook and loop fastener and the hook and loop fastener; the fleece side is disposed on the inner side of the outer curtain along the length of the outer curtain; the hook and loop fastener is disposed on the outer side of the inner curtain along the length of the inner curtain.

[0021] Preferably, the inner side of the overlapping area is provided with a third drive mechanism installed on the frame, and an arc-shaped bent rod connected to the third drive mechanism for being driven by the third drive mechanism to extend and retract to the outside of the frame.

[0022] Preferably, a spherical bearing is installed in the middle of the curved rod, and the spherical bearing is connected to the third drive mechanism.

[0023] Preferably, the curved rod is a rubber roller or roller shaft with a rubber layer wrapped around its surface.

[0024] Preferably, it also includes a distance sensor and a controller. The distance sensor is used to monitor the distance between the top of the vegetables and the roof in real time. The controller controls the lifting rod to rise and fall according to the monitoring data of the distance sensor so that the distance between the top of the vegetables and the roof is within a preset range.

[0025] Preferably, the distance sensor is mounted on the top of the canopy.

[0026] Preferably, it also includes a wind speed sensor for monitoring wind speed. The wind speed sensor is connected to the controller and sends a command signal to the controller when the data it measures reaches a threshold. After receiving the command signal, the controller controls each lifting rod to descend synchronously to a preset height.

[0027] Preferably, the wind speed sensor is mounted on the top of the canopy.

[0028] This invention comprises a frame, lifting rods, and a roof forming a lifting skeleton. A curtain roll, working in conjunction with this skeleton, creates a height-adjustable closed space above the vegetable planting area. This dynamically matches the crop's growth needs, providing lower space during the seedling stage to reduce energy consumption and provide a stable microclimate, while offering higher space for mature plants (such as tomatoes and cucumbers) to support stem and leaf extension. This invention upgrades traditional static agricultural facilities into a dynamic response system, trading flexibility for higher resource efficiency and resilience, making it suitable for planting scenarios with limited resources or variable environments.

[0030] Figure 2 This is a schematic diagram of the curtain roll structure in a vegetable planting dynamic response facility proposed in this invention;

[0031] Figure 3 This is a schematic diagram showing the distribution of the inner and outer curtain rolls in a vegetable planting dynamic response facility proposed in this invention. Detailed Implementation

[0032] Reference Figure 1 The present invention proposes a dynamic response facility for vegetable cultivation, comprising: a frame 1, a lifting rod 2, a roof 3, and a curtain roll 4, wherein:

[0033] The enclosure 1 is formed by connecting multiple panels end to end, and is used to enclose the outer perimeter of the vegetable planting area. Specifically, the included angle between two adjacent panels is an obtuse angle.

[0034] The lifting rod 2 is vertically installed on the frame 1, and there are multiple lifting rods 2, which are arranged at circumferential intervals along the frame 1. Specifically, the lifting rod 2 is an electric lifting rod or a pneumatic lifting rod.

[0035] The canopy 3 is positioned above the frame 1 and supported by the lifting rod 2, so that the canopy 3 can rise and fall with the lifting rod 2.

[0036] The curtain roll 4 includes a core tube 41 and a curtain 42 wound around the core tube 41. Multiple curtain rolls 4 are arranged sequentially around the perimeter of the frame 1, with the core tube 41 of each curtain roll 4 rotatably mounted on the frame 1. The free end of the curtain 42 of each curtain roll 4 is connected to the roof 3. This creates a closed space around the vegetable planting area. When the roof 3 rises, the curtain 41 automatically unrolls, increasing the height of the planting area. When the roof 3 falls, the curtain 41 is unrolled again, decreasing the height of the planting area.

[0037] Reference Figure 2 In a further embodiment, the curtain 42 is made of a light-transmitting film and is divided into multiple light-transmitting areas 421 along its length. Each light-transmitting area 421 has a different color depth so that the light transmittance of each light-transmitting area is different. The canopy 3 has multiple rotatable rollers 5 installed around its circumference. The free ends of each curtain 42 are wound onto the corresponding rollers 5. By rotating the rollers 5 to wind the curtain 42, the corresponding light-transmitting areas 421 in the curtain 42 are opened. The color depth difference of different light-transmitting areas 421 means that each area can transmit light of specific wavelengths, such as red and blue light areas to promote photosynthesis, and green light areas to reduce light pressure. Then, during operation, the curtain 42 can be unrolled or rolled up to open the corresponding light-transmitting areas 421, so as to match the best spectrum for different growth stages of vegetables, such as the seedling stage which requires weak light and the fruiting stage which requires strong light, or different vegetable varieties such as leafy vegetables and fruit vegetables, to optimize the growth cycle and nutrient accumulation. At the same time, the amount of light can be flexibly adjusted according to the weather or season, avoiding the problems of over-shading or under-shading of traditional fixed shade nets. Furthermore, the zoned design with varying light transmittance creates a continuous light gradient within the planting area, suitable for intercropping vegetables with different light sensitivities, such as light-loving tomatoes and shade-tolerant spinach, improving space utilization. Specific colors, such as yellow to attract aphids and silver to repel thrips, can be used in conjunction with biological control, reducing the use of chemical pesticides. Therefore, the zoned design with varying light transmittance along the length of the curtain 42 enables dynamic spectral management and precise control of the physical environment, significantly improving light energy utilization efficiency and vegetable quality while reducing environmental control energy consumption. This makes it particularly suitable for multi-variety, intensive, or organic vegetable cultivation scenarios.

[0038] In a further embodiment, the curtain 42 also includes a ventilation zone 422, which is densely covered with several through holes. When it is necessary to increase the ventilation effect in the planting area, the roller 5 is rotated so that the ventilation zone 422 of the curtain 42 enters the unfolded state, thereby ensuring the ventilation effect.

[0039] In a further embodiment, a first drive mechanism for driving the core cylinder 41 to rotate and a second drive mechanism for driving the roll 5 to rotate are also included. The first drive mechanism and the second drive mechanism automatically control the winding / unwinding of the curtain 42, which is more efficient than manual adjustment and is suitable for large-scale planting.

[0040] Reference Figure 3 In a further embodiment, the curtain roll 4 is divided into inner and outer layers. Each pair of adjacent inner curtain rolls 4 has a corresponding outer curtain roll 4 on its outer side, and the curtain 42 of the outer curtain roll 4 overlaps with the curtains 42 of its two adjacent inner curtain rolls 4 in an area 6. This allows the outer curtain 42 to cover the gap between two adjacent inner curtain rolls 42, ensuring a closed space around the vegetable planting area.

[0041] In a further embodiment, the overlapping area 6 of the outer curtain 42 and the inner curtain 42 is connected to each other by connecting accessories. The connecting accessories include a soft magnetic adsorption tape made of soft magnetic material and a flexible tape containing magnetic material; the soft magnetic adsorption tape is disposed on the inner side of the outer curtain 42 along the length direction of the outer curtain 42; the flexible tape is disposed on the outer side of the inner curtain 42 along the length direction of the inner curtain 42; or the connecting accessories include a fleece tape and a hook tape of hook and loop fasteners; the fleece tape is disposed on the inner side of the outer curtain 42 along the length direction of the outer curtain 42; the hook tape is disposed on the outer side of the inner curtain 42 along the length direction of the inner curtain 42; this allows the inner curtain 42 and the outer curtain 42 to be connected together at the contact surface by magnetic adsorption or hook and loop fasteners when unfolded, and to automatically separate when rolled up.

[0042] In a further embodiment, a third drive mechanism mounted on the frame 1 is provided inside the overlapping area 6, and an arc-shaped curved rod 7 with its axis facing inward and connected to the third drive mechanism for telescopic movement outward by the third drive mechanism. Specifically, a spherical bearing is installed in the middle of the arc-shaped curved rod 7, and the spherical bearing is connected to the third drive mechanism. The surface of the arc-shaped curved rod 7 is covered with a rubber layer. During operation, the arc-shaped curved rod 7 can be driven outward by the third drive mechanism to laterally expand the internal space.

[0043] In a further embodiment, the canopy 3 is equipped with vents, sprinkler heads, and LED plant growth lights. The vents provide ventilation, the sprinkler heads provide water and pesticides, and the LED plant growth lights provide the light required for plant photosynthesis in cases of insufficient sunlight or indoor conditions.

[0044] In a further embodiment, a distance sensor and a controller are also included. The distance sensor is installed on the top of the canopy 3 to monitor the distance between the highest point of the vegetables and the canopy 3 in real time. The controller controls the lifting rod 2 to rise and fall according to the data monitored by the distance sensor to keep the distance between the highest point of the vegetables and the canopy 3 within a preset range. This enables adaptive adjustment of the height of the canopy 3, ensuring consistency of the distance between the plants and the light source, ensuring uniform light exposure for the plants, and avoiding scorching caused by the plants being too close to the light source. Furthermore, in practice, the preset range of the distance between the highest point of the vegetables and the canopy 3 can be adjusted and modified according to different growth stages of the vegetables.

[0045] In a further embodiment, a wind speed sensor is also included for monitoring wind speed. The wind speed sensor is installed on the top of the canopy 3 and connected to the controller. When the measured data reaches a threshold, the wind speed sensor sends a command signal to the controller. Upon receiving the command signal, the controller controls each lifting rod 2 to descend synchronously to a preset height. This structural design can automatically lower the height of the canopy 3 in the event of heavy snow or strong winds, thereby reducing structural stress and preventing collapse.

[0046] As can be seen from the above, this invention utilizes the frame 1, lifting rod 2, roof 3, and curtain roll 4 in cooperation to form a closed space above the vegetable planting area that can be adjusted in height. This achieves the purpose of dynamically matching the needs of crop growth, providing lower space during the seedling stage to reduce energy consumption and provide a stable microclimate, while providing higher space for mature plants such as tomatoes and cucumbers to support stem and leaf extension. This invention upgrades traditional static agricultural facilities into a dynamic response system, trading flexibility for higher resource efficiency and risk resistance, making it suitable for planting scenarios with limited resources or variable environments.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
