Description

Technical Field

[0001] This utility model relates to the field of shade frame technology, and in particular to a shade frame for Dendrobium cultivation. Background Technology

[0002] Dendrobium, also known as Wanzhangxu, Jinchaishi, Bianjinchai, Bianhuangcao, and Biancao, is a perennial herb named for its resemblance to an ancient hairpin. Its stems grow in clusters, with the upper part slightly flattened and curved upwards, reaching a height of 10-60 cm and a diameter of up to 1.4 cm. During the cultivation of Dendrobium, it is necessary to provide shade according to the needs of Dendrobium cultivation.

[0003] Existing shade frame greenhouses for Dendrobium cultivation are mostly simple in structure, consisting of a frame and shade cloth. However, Dendrobium needs sunlight during this process, and traditional shade frames require manual pulling of the shade net, which is time-consuming, labor-intensive, and poses safety hazards. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to propose a shading frame for Dendrobium cultivation that enables the automatic opening and closing of the shading cloth without manual intervention, significantly reducing labor intensity and operation time, while eliminating the safety hazards of manual operation.

[0005] The Dendrobium officinale planting shade frame proposed in this utility model includes four support legs, a top cover fixed to the top of the four support legs, a winding shaft rotatably connected between two of the support legs, a worm gear fixed to one end of each support leg, a first motor fixed to one side of one of the support legs, a worm gear meshing with the worm gear fixed to the rotating end of the first motor, a helical gear fixed to the other end of the winding shaft, and helical gears fixed to both ends of a pair of winding shafts away from the worm gear, while helical gears fixed to the other ends of a pair of winding shafts adjacent to the worm gear, and the helical gears meshing in pairs to form a closed-loop transmission chain, and a shade cloth fixed to the outer surface of the winding shaft;

[0006] The top cover has windows at both the left and right ends, and a pair of rotating shafts are rotatably connected inside the windows. A shading plate is fixed to the outer surface of the rotating shafts.

[0007] Preferably, a counterweight is fixed to the bottom of the sunshade cloth.

[0008] Preferably, one side of the support leg is provided with a guide groove that cooperates with the counterweight rod.

[0009] Preferably, a pulley is fitted on the outer surface of the rotating shaft, a belt is fitted between the two pulleys, a second motor is fixed on one side of the top cover, and the rotating end of the second motor is fixed to the rotating shaft.

[0010] Preferably, a connecting plate for interconnection is fixed between the four support legs.

[0011] Preferably, the width of the sunshade cloth is adapted to the distance between the two supporting legs.

[0012] The beneficial effects of this utility model are:

[0013] 1. The automatic unfolding and retraction of the sunshade cloth is achieved by driving a worm gear transmission and helical gear linkage mechanism through a first motor. The self-locking characteristic design of the worm gear transmission mechanism ensures that the sunshade cloth will not accidentally slip due to wind or gravity when stationary, improving safety. No manual intervention is required, significantly reducing labor intensity and operation time, while eliminating the safety hazards of manual operation. Multiple take-up shafts form a synchronous transmission chain through helical gear meshing, ensuring that the sunshade cloth is evenly stressed when unfolded, avoiding deformation or damage caused by localized pulling, and extending the service life of the sunshade cloth.

[0014] 2. The second motor drives the shading plate rotation shaft and pulley belt mechanism, which can flexibly adjust the tilt angle of the shading plate to achieve precise control of light transmittance, which can not only meet the photosynthetic needs of Dendrobium, but also adapt to environments with different light intensities.

[0022] Reference Figure 1-6 The shading frame for Dendrobium cultivation includes four support legs 1, which serve as the main support structure. A top cover 2 is fixed to the top of each support leg 1. A winding shaft 3 is rotatably connected between two support legs 1. A worm gear 4 is fixed to one end of each support leg 1. A first motor 5 is fixed to one side of one of the support legs 1. A worm 6, meshing with the worm gear 4, is fixed to the rotating end of the first motor 5. A helical gear 7 is fixed to the other end of the winding shaft 3. Helical gears 7 are fixed to both ends of a pair of winding shafts 3 furthest from the worm gear 4, and helical gears 7 are fixed to the other ends of a pair of winding shafts 3 adjacent to the worm gear 4. The helical gears 7 mesh in pairs to form a closed-loop transmission chain. A shading cloth 8 is fixed to the outer surface of the winding shaft 3. When the first motor 5 starts, the worm 6 drives the worm gear 4 to rotate, which in turn drives the winding shaft 3 to rotate. The helical gear 7 is fixed to the other end of the winding shaft 3 and meshes with the helical gear 7 on the adjacent winding shaft 3, forming a linkage transmission chain. This design enables multiple take-up shafts 3 to move synchronously, ensuring that the sunshade cloth 8 is evenly stressed when it is unfolded. When the sunshade cloth 8 needs to be retracted, the first motor 5 drives the take-up shaft 3 to rotate, wrapping the sunshade cloth 8 around the surface of the take-up shaft 3. The counterweight rod 15 rises along the guide groove 14 to the bottom of the top cover 2 to avoid blocking the sunlight, thus realizing the unfolding and retraction of the sunshade cloth 8.

[0023] The top cover 2 has windows on both the left and right sides for installing the shade plate 10 and the rotating shaft 9. A pair of rotating shafts 9 are rotatably connected inside the windows. The shade plate 10 is fixed on the outer surface of the rotating shaft 9. The outer surface of the rotating shaft 9 is fitted with pulleys 11. A belt 12 is fitted between the two pulleys 11. A second motor 13 is fixed on one side of the top cover 2. The rotating end of the second motor 13 is fixed to the rotating shaft 9. When the second motor 13 is started, the belt 12 drives the rotating shaft 9 to rotate, causing the shade plate 10 to rotate around the rotating shaft 9, adjusting the tilt angle of the shade plate 10, thereby precisely controlling the light transmittance.

[0024] A counterweight rod 15 is fixed to the bottom of the sunshade cloth 8. A guide groove 14 that cooperates with the counterweight rod 15 is opened on one side of the support leg 1. The counterweight rod 15 is embedded in the guide groove 14 on the side of the support leg 1, and the sunshade cloth 8 is kept vertically unfolded by gravity.

[0025] Connecting plates 16 are fixed between the four supporting legs 1 for interconnection. The connecting plates 16 are fixed to the supporting legs 1 to form a rectangular frame.

[0026] The width of the sunshade 8 is matched with the distance between the two support legs 1.

[0027] When using this device, to unfold the shade cloth 8, the first motor 5 is activated, causing the worm gear 6 to drive the worm wheel 4 to rotate, which in turn drives the take-up shaft 3 to rotate counterclockwise. The shade cloth 8 is released from the surface of the take-up shaft 3, and the counterweight rod 15 moves down along the guide groove 14 until the shade cloth 8 is fully unfolded. To retract the shade cloth 8, the first motor 5 is activated again, driving the take-up shaft 3 to rotate clockwise, wrapping the shade cloth 8 around the surface of the take-up shaft 3 until the shade cloth 8 is fully retracted. The linkage helical gear 7 ensures that all take-up shafts 3 operate synchronously, and the shade cloth 8 flatly covers the planting area. Depending on the light intensity, the second motor 13 can be activated to drive the rotating shaft 9 to rotate. The shade plate 10 is then adjusted to the required angle, at which point some sunlight is projected onto the Dendrobium plants through the gaps in the shade plate 10, meeting their photosynthetic needs. If full shading is required, the shade plate 10 is adjusted to a horizontal position; if increased light is required, it is adjusted to a vertical position.
