Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of greenhouse curtain equipment, specifically to a side-rolling cotton quilt system. Background Technology
[0002] The side-rolling quilt system is an important piece of equipment for achieving automated management of greenhouses. Its main functions are temperature regulation, light management, and optimization of the crop growth environment. For example, in cold weather or when it is necessary to reduce the amount of sunlight for crops, the quilt is rolled up to cover the sides of the greenhouse, reducing heat loss from inside the greenhouse or blocking sunlight; in hot weather or when it is necessary to ensure that crops receive sunlight, the quilt can be rolled up.
[0003] However, the peripheral surfaces of the greenhouse sides are usually curved, such as... Figure 3 As shown, existing side-rolling quilt systems use straight quilt-rolling rods. When directly applied to curved surfaces, these rods are prone to mismatch due to structural issues, resulting in the quilt being unable to conform to the surface. This causes the quilt to be partially suspended or overstretched, leading to problems such as uneven quilt unfolding and retracting, poor covering effect, and even potential overload damage to system equipment such as the roller shutter motor. Therefore, a side-rolling quilt system suitable for curved greenhouses is needed. Utility Model Content
[0004] To address the problems in the background art, this utility model proposes a side-rolling quilt system, including a first roller rod, a second roller rod, a side-mounted electric roller shutter machine, and a support rod. There are two second roller rods. The two ends of the first roller rod are respectively hinged to one end of the two second roller rods. The other end of one second roller rod is connected to the output end of the side-mounted electric roller shutter machine. One side of the side-mounted electric roller shutter machine is hinged to one end of the support rod, and the other end of the support rod is rotatably connected to the ground. Preferably, the first reel is connected to the two second reels via a universal coupling.
[0005] Preferably, the output end of the side-mounted electric roller shutter is provided with a first flange, and one end of the second roller rod connected to the side-mounted electric roller shutter is fixed with a second flange that matches the first flange. The first flange and the second flange are connected by bolts.
[0006] Preferably, a connecting rod is fixed on one side of the side-mounted electric roller shutter, and a first ear plate is provided at the end of the connecting rod away from the side-mounted electric roller shutter; One end of the support rod is rotatably connected to a second ear plate, and the first ear plate is rotatably connected to the second ear plate. The rotation axis of the first ear plate is perpendicular to the rotation axis of the second ear plate.
[0007] Preferably, the first ear plate and the second ear plate are connected by a rotating rod, which passes through the first ear plate and the second ear plate, and the two ends of the rotating rod extend out of the second ear plate. The extended ends of the rotating rod are threaded with limit nuts.
[0008] Preferably, it also includes a base, which is fixed to the ground. The end of the support rod away from the side-mounted electric roller shutter is provided with a third ear plate, and a fourth ear plate is fixed on the base. The third ear plate and the fourth ear plate are rotatably connected.
[0009] The beneficial effects of this utility model are as follows: The quilt-rolling rod of this utility model includes a first and a second rod hinged together. The two rods can rotate relative to each other at the curved surface, improving adaptability to the outer side of the greenhouse. Furthermore, during the unfolding and retraction process, because the side-mounted electric quilt-rolling machine is hinged to the support rod and the support rod is rotatably connected to the ground, the side-mounted electric quilt-rolling machine can follow the position of the quilt and perform rotation and tilting movements while driving the quilt-rolling and retraction. This prevents the quilt from getting stuck during unfolding and retraction, improves the smoothness of quilt unfolding and retraction, and greatly reduces the possibility of overload damage to the side-mounted electric quilt-rolling machine due to quilt unfolding and retraction jamming.
[0010] This invention is applicable to the unfolding and retraction of cotton quilts in curved greenhouses, improving the matching degree between the cotton quilt and the greenhouse surface, thereby ensuring the smoothness of the unfolding and retraction process, improving the covering effect of the cotton quilt, and at the same time avoiding overload damage to the system equipment and ensuring the service life of the equipment.

There are two second roller rods 2. The two ends of the first roller rod 1 are respectively hinged to one end of the two second roller rods 2. The other end of one second roller rod 2 is connected to the output end of the side-mounted electric roller shutter machine 5. One side of the side-mounted electric roller shutter machine 5 is hinged to one end of the support rod 3, and the other end of the support rod 3 is rotatably connected to the ground. Specifically, the first winding rod 1 is connected to the two second winding rods 2 via a universal coupling 4.
[0016] Specifically, the output end of the side-mounted electric roller shutter 5 is provided with a first flange 15, and one end of the second roller rod 2 connected to the side-mounted electric roller shutter 5 is fixed with a second flange 12 that matches the first flange 15. The first flange 15 and the second flange 12 are connected by bolts 14. The structure of using bolts 14 to connect the flanges facilitates the assembly and disassembly of the second roller rod 2 and the side-mounted electric roller shutter 5.
[0017] Specifically, a connecting rod 6 is fixed on one side of the side-mounted electric roller shutter 5, and a first ear plate 7 is provided at the end of the connecting rod 6 away from the side-mounted electric roller shutter 5. One end of the support rod 3 is rotatably connected to a second ear plate 8. The first ear plate 7 and the second ear plate 8 are rotatably connected, and the rotation axis of the first ear plate 7 is perpendicular to the rotation axis of the second ear plate 8. The rotation axis of the first ear plate 7 is the rotation axis at the rotatable connection between the first ear plate 7 and the second ear plate 8, and the rotation axis of the second ear plate 8 is the rotation axis at the rotatable connection between the second ear plate 8 and the support rod 3. The side-mounted electric roller shutter 5 can perform rotation and tilting movements.
[0018] Specifically, the first ear plate 7 and the second ear plate 8 are connected by a rotating rod 9, which passes through the first ear plate 7 and the second ear plate 8, and the two ends of the rotating rod 9 extend out of the second ear plate 8. The extended ends of the rotating rod 9 are threadedly connected to a limit nut 10.
[0019] Specifically, it also includes a base, which is fixed to the ground. A third ear plate 11 is provided at the end of the support rod 3 away from the side-mounted electric roller shutter 5. A fourth ear plate is fixed on the base, and the third ear plate 11 and the fourth ear plate are rotatably connected. The rotation axis of the support rod 3 relative to the ground is parallel to the axes of the first roller rod 1 and the second roller rod 2, allowing the support rod 3 to swing along the direction of quilt operation during quilt raising and lowering. This enables the side-mounted electric roller shutter 5 to move accordingly and adapt to different ceiling heights, improving the smoothness of quilt raising and lowering.
[0020] More specifically, the base can be made of steel or alloy material and is connected to the ground by anchor bolts.
[0021] During setup, the support rod 3 and the side-mounted electric roller shutter 5 are located on one side of the greenhouse side 13.
