Description

Technical Field

[0001] This invention belongs to the field of agricultural equipment technology, and in particular relates to a shading system that facilitates the adjustment of light levels within agricultural facilities. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Shade nets are protective covering materials used in agricultural production, especially within agricultural facilities. They provide shade, moisture retention, and cooling. However, traditional shade nets cannot adjust the shading location, shading rate, and shading intensity according to the actual conditions of the plants (including edible fungi). When plants require high light intensity, they are still in low light, resulting in weak and leggy plants. Conversely, when plants or edible fungi require low light, the light intensity cannot be reduced in time, potentially scorching the plants or fungi.

[0004] Traditional shade nets have relatively fixed shading positions and angles, and cannot be adjusted according to the growth of plants or edible fungi. Plants or edible fungi may bend due to unidirectional light exposure. Traditional shade nets cannot simultaneously meet the needs of light source position, light source angle and shading. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a shading system that facilitates the adjustment of light levels within agricultural facilities.

[0006] To achieve the above objectives, one or more embodiments of the present invention provide the following technical solutions:

[0007] This invention provides a shading system for easily adjusting light levels in agricultural facilities, characterized by comprising:

[0008] The sunshade assembly is a double-layer sunshade structure, including an upper sunshade curtain and a lower sunshade curtain. Both the upper and lower sunshade curtains include multiple spaced sunshade curtain panels, and the horizontal distance between two adjacent sunshade curtain panels is the width of one sunshade curtain panel.

[0009] A fixed frame is located at the left and right ends of the sunshade assembly. It has a built-in suspended fixed shaft and a rotating shaft. The rotating shaft is equipped with a transmission component. The two ends of the upper sunshade curtain are respectively wound on the rotating shaft, and the two ends of the lower sunshade curtain are respectively wound on the fixed shaft. The transmission component drives the rotating shaft to rotate, thereby driving the upper sunshade curtain to move, so that the upper and lower sunshade curtains overlap or stagger. With the help of the flipping component, the shading area, shading intensity and light transmission angle can be adjusted.

[0010] The above one or more technical solutions have the following beneficial effects:

[0011] (1) The adjustable shading system provided by the present invention breaks the inherent pattern of traditional shading nets. The shading position and light transmission intensity of the shading curtain can be adjusted by pulling the rope, so as to change the shading degree from 0 to 100%. At the same time, the shading position can be changed according to specific needs. That is, by rotating the rotating shaft, the upper shading curtain can be moved to the left or right to achieve different degrees of overlap between the upper and lower curtains, thereby changing the shading position and light transmission. At the same time, the upper and lower curtain panels can be rotated at a certain angle to achieve the required greater light transmission. This solves the problem that the angle of the existing shading structure cannot be changed, and it cannot meet the needs of lighting and shading at the same time.

[0012] (2) The shading curtain of the present invention has a perforated structure or is semi-transparent. Different types of shading curtains with different light leakage densities can be replaced according to different seasons and different growth stages of crops to create an optimal environment conducive to plant growth and development.

[0013] (3) The sunshade curtain of the present invention uses low-cost, environmentally friendly and durable materials such as polyethylene propylene, nylon and stainless steel, which reduces the production cost, increases the service life of the sunshade curtain, and is easy to operate, thus increasing the cost-effectiveness of the adjustable sunshade net.

[0014] Advantages of additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0027] Example 1

[0028] like Figure 1 As shown, this invention discloses a shading system that facilitates the adjustment of light in agricultural facilities. The shading system is shaped like a cuboid at both ends with a double-layered strip-shaped shading curtain in the middle. Its purpose is to adjust the shading position, shading degree, and shading time at any time to meet the light requirements of plants and prevent adverse phenomena such as excessive growth, scorching, and phototropism.

[0029] like Figure 2 , Figure 3 As shown, the sunshade system includes: a double-layer sunshade curtain structure and a fixed frame 1. The fixed frame 1 is located at the left and right ends of the double-layer sunshade curtain structure. The fixed frame 1 is equipped with a rotating shaft 7 and a support shaft 9. The fixed shaft 10 is located below the rotating shaft 7. There are two support shafts 9 in each fixed frame 1, which are symmetrically fixed on the fixed frame 1. The two ends of the rotating shaft 7 are connected to the support shaft through a rotating gear 8.

[0030] A traction rope 3 is wound around the rotating gear 8, and the winding length of the traction rope 3 is the width of two sunshade panels. A traction rope fixing device 11 is installed on the support shaft 9, which is compatible with the rotating gear 8. The traction rope 3 is made of nylon rope and is connected to the rotating shaft 7 through the traction rope fixing device 11. The rotating shaft 7 can be rotated by adjusting the traction rope 3.

[0031] One end of the traction rope 3 passes through the small hole of the traction tension fixing device 11 and is clamped by the slot therein. There is a clamping bar on the slot, which makes the traction rope 3 firmly clamped into the slot to prevent it from falling off.

[0032] The double-layer sunshade structure includes an upper sunshade 4 and a lower sunshade 5, with the vertical spacing between the upper sunshade 4 and the lower sunshade 5 being the width of a sunshade panel. The two ends of the upper sunshade 4 are respectively wound around a rotating shaft 7 inside a fixed frame 1, and the two ends of the lower sunshade 5 are respectively fixed to a fixed shaft 10 inside a fixed frame 1. The rotating shaft 7 and the fixed shaft 10 are stacked one on top of the other inside the fixed frame 1. The rotating shaft 7 is driven to rotate by pulling the traction rope 3, and the rotation of the rotating shaft 7 drives the upper sunshade wound on the rotating shaft 1 to move, thereby adjusting the sunshade position and sunshade area.

[0033] like Figure 4 , Figure 5 As shown, the double-layer sunshade structure consists of an upper sunshade 4 and a lower sunshade 5. Each layer of sunshade consists of an array of multiple sunshade slats 16 spaced at equal intervals. The sunshade slats 16 are used to hold the sunshade slats. The sunshade system is flipped by the slat fastener 25 and the flipping belt 19 forming an integrated structure. The length and width of each sunshade slat are slightly larger than the length and width of each sunshade slat. The spacing between two adjacent sunshade slats 16 is equal to the width of the sunshade slat 16, and the vertical spacing between the upper and lower layers of sunshade is the width of one sunshade slat.

[0034] Each sunshade panel is supported by two steel wires 6, which run along the length of the sunshade panel 16 and are integral with it, ensuring the stability between the panel and the panel. The sunshade is made of high-density polyethylene and polypropylene, which are characterized by high tensile strength, aging resistance, corrosion resistance, radiation resistance, and lightweight. The length, width, and number of panels between the fixed frames of the sunshade of this invention can be adjusted according to specific production applications.

[0035] When the double-layer sunshade structure is in its initial position, it is in a full-shade state. One end of the upper sunshade 4 is wound around the left-hand rotating shaft in the horizontal direction, and the other end is fixedly connected to the right-hand rotating shaft in the horizontal direction. When the pull cord 3 on the right-hand rotating shaft is pulled, the rotating shaft rotates to the right, causing the right end of the upper sunshade 4 to be wound around the right-hand rotating shaft. At the same time, the end of the upper sunshade 4 wound around the left-hand rotating shaft unfolds, thus moving the upper sunshade 4 horizontally to the right until the sunshade panels of the upper and lower layers of sunshade completely overlap, which is a half-shade state. When the pull cord 3 on the right-hand rotating shaft is pulled further, the overlapping part of the upper and lower layers of sunshade panels gradually decreases until there is no overlap, which is a full-shade state.

[0036] When the upper and lower sunshade curtain panels overlap, pulling the traction rope 3 on the left rotating shaft will rotate the shaft to the left, causing the upper sunshade curtain 4 to move horizontally to the left, allowing for flexible adjustment of the sunshade level at any time.

[0037] Because the upper shading curtain 4 moves horizontally while the lower shading curtain 5 does not move, the upper and lower shading curtains achieve full overlap → partial overlap → no overlap, thus adjusting the shading rate from 50% to 100%. Furthermore, when the upper and lower shading curtains fully overlap, the shading rate is 50%. When the upper and lower shading curtains partially overlap, the shading rate is greater than 50% but less than 100%. When the upper and lower shading curtains do not overlap, the shading rate can reach 100%.

[0038] In this embodiment, the traction rope is fixed by a traction rope fixer, and the winding length of the traction rope 3 and the length of the upper sunshade curtain rolled on the rotating shaft are the width of two sunshade curtain panels, so as to limit the movement distance of the upper sunshade curtain, so that its maximum movement distance to the left or right is the width of one sunshade curtain panel, thereby avoiding the rolling of the upper sunshade curtain panel.

[0039] The traction rope 3 is made of nylon rope. Nylon rope has high wear resistance, is not easy to age, is corrosion-resistant, and is resistant to sunlight. At the same time, it has a low density and can withstand greater tensile force, which further ensures the normal operation of the sunshade system.

[0040] Further, such as Figure 6 As shown, a flipping component 2 is also provided on one side of the fixed frame 1. The flipping component 2 is connected to the transmission device 21, which is fixed at both ends of each sunshade slat. By rotating the flipping component 2, the flipping belt 19 and the transmission device 21 are rotated to achieve the flipping of the sunshade slats. The transmission device 21 is provided with a first movable fixing hole 17. After the flipping belt 19 passes through the first movable fixing hole 17, it is connected to the sunshade slats in sequence through the adjusting support arm 22.

[0041] Each sunshade panel is connected to a flipping belt 19 on both sides through flipping holes 20. The flipping belt 19 extends along the length of the sunshade panel and includes a transmission device 21. By rotating the flipping component 2, the flipping belt 19 is rotated, and the transmission device 21 then flips each sunshade panel 16, achieving different tilt angles for the sunshade panels.

[0042] In this invention, the flipping component 2 is integrated with the sunshade slat 16 and the flipping belt 19. The flipping component 2 is installed on both sides of the sunshade. The flipping component includes a manual knob 201 and a connecting cylinder 202. Each sunshade slat has flipping holes at both ends. Each flipping hole is integrated with the adjusting arm 22 through the slat fastener 25, so as to cooperate with the transmission device 21 and the flipping belt 19. Rotating the manual knob 201 in the flipping component 2 drives the connecting cylinder 202 to rotate, thereby driving the sunshade slat to flip.

[0043] The position of the light and the intensity of the light transmission can be adjusted by flipping the sunshade curtain by flipping the flipping component 2. The flipping of the sunshade curtain panel can achieve the tilt of the sunshade curtain panel from 0 to 90°. The flipping component 2 is set on the horizontal right side of the sunshade component, which can realize the flipping of the upper and lower sunshade curtain panels in the same direction and at the same angle from top to bottom.

[0044] The transmission device 21 is integrated with the connecting cylinder 202 via blades. The blade fixing hole 24 ensures the firmness of the transmission device. The rotation of the connecting cylinder 202 drives the transmission device 21 to rotate together. The transmission device 21 is provided with a first movable fixing hole 17. While fixing the flipping belt 19, it works with the second movable fixing hole 18 and the curtain slat fixer 25 to change the tilt angle of the sunshade slat, thereby realizing the angle change of the sunshade slat.

[0045] Furthermore, the adjustment arm is located on the two flip-up belts. By adjusting the arm and the second and first movable fixing holes, the flip-up belts can be tilted, causing the sunshade curtain panel to tilt. The adjustment arm can fix the tilt angle, allowing the sunshade curtain panel to tilt at different angles, ensuring flexible adjustment of its sunshade area.

[0046] It should be noted that the flip-up belt is connected and fixed via the adjusting arm 22. The fixing hole connecting the adjusting arm to the flip-up belt is movable, so the adjusting arm is not fixed and has a certain angle of inclination. The blade fixing hole 24 on the transmission device 21 is a fixed hole and cannot be moved, while the first movable fixing hole 17 is a movable fixing hole and also has a certain angle of inclination. Therefore, the tilt angle of the flip-up belt is fixed by the adjusting arm, while the first movable fixing hole 17 allows the flip-up belt to tilt. Simultaneously, the manual knob 201 is rotated to achieve the flip-up. The curtain slat fastener 25 on the adjusting arm 22 connects to the sunshade curtain slats. As the height of the two flip-up belts 19 changes, the tilt angle of the adjusting arm 22 also changes, achieving the tilt of the sunshade curtain slats.

[0047] like Figure 7 , Figure 8 As shown, blade 23 is a transition device, mainly used to connect the transmission device 21 and the connecting cylinder 202. The transmission device 21 is fixed to the blade through the blade fixing hole 24, which cannot be rotated. The first movable fixing hole and the second movable fixing hole have the same structure, but their positions are different. The first movable fixing hole is located on the transmission device and connected to the flipping belt, while the second movable fixing hole is located on the adjusting support arm and connected to the flipping belt.

[0048] By combining the flip mechanism with different tilt angles, the shading rate can be adjusted from 0% to 50%. When the upper and lower shading curtains are flipped, they tilt at the same angle. When both are parallel to the sun's direction at a certain angle, the shading rate is 0% (excluding the shading effect of the curtain thickness itself). When the flip angle is at a certain angle to the sun's direction, the shading rate is between 0% and 50%. The flip function can only be used when the upper and lower shading curtains are completely overlapped.

[0049] By moving the upper shading curtain to the left or right, partial overlap of the upper and lower curtain slats can be achieved at different positions. Alternatively, by tilting the upper and lower curtain slats at different angles, different shading rates and shading positions can be changed in real time. The upper shading curtain can also be moved horizontally left or right according to the season, sun position, and shading needs, so that the shading position changes horizontally.

[0050] like Figure 9 , Figure 10 As shown, a movable lifting device 12 is also installed on the fixed frame. The principle of the movable lifting device 12 is similar to that of the clothes drying rack. The movable lifting device 12 is connected to the greenhouse frame 13 and the fixed frame 1 through pulleys. The movable device 12 is installed on the front of the two fixed frames 1 at the first and last ends, which can drive the movement of the entire shading system and play the role of fixing and moving.

[0051] This system can be installed inside agricultural facilities to provide internal shading, or it can be installed above the outside of agricultural facilities to provide external shading.

[0052] Although the above describes the specific embodiments of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without any creative work are still within the scope of protection of the present invention.
