Description

Technical Field

[0001] The utility model belongs to the technical field of planting greenhouses, and in particular relates to a rolling curtain mechanism of a planting greenhouse. Background Art

[0002] Greenhouse cultivation refers to building a closed planting system and using modern scientific and technological means to control the internal environment, including temperature, humidity, light and other factors, to create conditions suitable for plant growth. Compared with traditional open-air cultivation, greenhouse cultivation has the characteristics of strong environmental control ability, short production cycle, and stable high yield. Tibetan Fritillaria, Tibetan Angelica, and Tibetan Peach require a relatively warm environment in the breeding stage. In a planting environment with a large temperature difference between day and night, it is necessary to lay a shade curtain in the planting greenhouse at night and remove the shade curtain when the temperature is high during the day. When the shade curtain is used, it needs to be manually rolled and rolled up after being removed from the planting greenhouse. Not only is the rolling efficiency low and time-consuming, but the rolled-up shade curtain is not regular enough. During subsequent disassembly, it is easy to get tangled, affecting the efficiency of laying again. Therefore, the inventor proposed a rolling curtain mechanism for a planting greenhouse.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] This specific implementation is a rolling shutter mechanism for a planting greenhouse, and its structural schematic diagram is as follows Figure 1 As shown, it includes a frame 1, a support plate 3, a winding shaft 4, a fixed disk 6 and a clamping plate 5. The support plate 3 is vertically mounted on the frame 1. A plurality of groups of rotating disks 2 are vertically spaced and distributed on the support plate 3. The plurality of groups of rotating disks 2 are rotatably connected to the support plate 3. The winding shaft 4 is fixedly mounted on a side of the rotating disk 2 away from the support plate 3, and the rotating disk 2 and the winding shaft 4 are cocentrically distributed. The end of the winding shaft 4 away from the rotating disk 2 is fixedly connected to the fixed disk 6.

[0024] Reference Figure 2 A driving disk 8 is rotatably mounted on one side of the support plate 3 away from the rotating disk 2. The driving disk 8 is connected to the rotating disk 2 and is cocentrically distributed. An operating rod 7 is fixed to the outer surface of the driving disk 8 near the side. A groove 9 is provided on the outer circumferential surface of the driving disk 8. A limiting screw 10 is inserted into the groove 9. A fixing block 11 is provided on the outer thread sleeve of the limiting screw 10, and the fixing block 11 is fixed to the outer wall of the support plate 3.

[0025] Reference Figure 3 , Figure 4 The inner side of the fixed disk 6 is concave, the clamping plate 5 and the fixed disk 6 are adapted to fit each other, and the clamping plate 5 is slidably sleeved on the outside of the winding shaft 4. The central part of the clamping plate 5 has a through hole 17 for the winding shaft 4 to pass through, and a vertical rod 16 is vertically fixed inside the through hole 17, and a connecting ring 15 is fixed at the end of the vertical rod 16. The internal thread of the connecting ring 15 passes through a driving screw 14, and the driving screw 14 is rotatably installed at the center of the fixed disk 6.

[0026] A moving groove 13 is horizontally opened on the surface of the winding shaft 4 , and the vertical rod 16 and the connecting ring 15 are inserted into the moving groove 13 to slide, and the driving screw 14 is rotatably arranged in the moving groove 13 .

[0027] Working principle: When in use, first move the frame 1 to the planting greenhouse. When the shade curtain outside the planting greenhouse needs to be removed, fit the side of the shade curtain with the winding shaft 4, and turn the operating lever 7, the operating lever 7 drives the driving disk 8 to rotate, and then the rotating disk 2 and the winding shaft 4 rotate synchronously. As the winding shaft 4 continues to rotate, the shade curtain is wound around the winding shaft 4 layer by layer. After the winding is completed, turn the driving screw 14, the driving screw 14 rotates to drive the connecting ring 15 to move along the external spiral, and the vertical rod 16 is forced to move along the moving groove 13 slides horizontally, and then the clamping plate 5 slides along the driving shaft under force, and the clamping plate 5 moves out from the inner side of the fixed disk 6 and approaches the rotating disk 2 to clamp the end of the shielding curtain to prevent the shielding curtain from falling. The shielding curtain is wound and rolled up on the reel 4, and the regularity is high. In subsequent use, the end of the shielding curtain is pulled, and the reel 4 rotates to release the shielding curtain. The moving distance of the clamping plate 5 is adjustable, and it can be adjusted according to the width of the shielding curtain. It is suitable for shielding curtains of different sizes at different positions in the planting greenhouse, and has a good fixing effect on the shielding curtain;

[0028] In order to further improve the fixing effect of the blackout curtain and prevent it from scattering during the movement of the frame 1, the rolled-up winding shaft 4 can be limited to prevent it from rotating. The limiting screw 10 is rotated to make it move spirally along the fixing block 11 and enter the groove 9. The driving disk 8 can be fixed. After the driving disk 8 is limited, the rotating disk 2 can no longer rotate, thereby limiting the blackout curtain.
