[0002] Greenhouses, also known as hothouses, are facilities that can transmit light, keep warm (or heat), and are used to grow plants. In seasons that are not suitable for plant growth, they can provide a greenhouse growth period and increase production. They are mostly used to grow or raise seedlings of warm-loving vegetables, flowers, trees, and other plants in low-temperature seasons. There are many types of greenhouses, which can be divided into many categories according to different roof frame materials, lighting materials, shapes, and heating conditions.

[0003] A greenhouse full-window ventilation system disclosed in Chinese utility model CN212279110U solves the problem of insufficient window opening angle, but the greenhouse full-window ventilation system still has the following disadvantages: First, when the top window is opened for ventilation and the wind force is strong, leaves, garbage, dust, etc. on the surrounding trees will enter the greenhouse through the top window, making the internal environment of the greenhouse less beautiful, and workers are required to clean up the debris inside the greenhouse frequently; Second, although the above-mentioned greenhouse full-window ventilation system improves the ventilation effect by increasing the window opening angle, the window opening angle of the greenhouse full-window ventilation system is still at an acute angle, which will cause the internal hot air to be discharged more slowly, thereby slowing down the rate at which the internal temperature drops.

The front of the first sliding rod 7 is fixedly connected to the second rack 22. The first sliding rod 7 is located in the middle of the second rack 22. The inner wall of the groove 3 is fixedly connected to the fixed rod 6. The fixed rod 6 is cylindrical. The fixed rod 6 is located between the first slide groove 5 and the second slide groove 4. The front of the fixed rod 6 is rotatably connected to the third gear 20. The third gear 20 is located directly above the second rack 22 and meshes with the second rack 22. The third gear 20 is located in the middle of the groove 3. The second rack 22 is located inside the shed body 1. The diameter of the third gear 20 is greater than the thickness of the shed body 1.

[0026] When in use, when the top window is opened for ventilation with a strong wind force, leaves, garbage, dust, etc. on the surrounding trees will enter the greenhouse through the top window, making the internal environment of the greenhouse not beautiful enough, and workers are required to clean up the debris inside the greenhouse frequently. When the top window needs to be opened, the motor 15 is started, the first rotating rod 13 starts to rotate, and the second sliding rod 8 slides to the left along the second sliding groove 4 as the windshield cloth 10 is rolled up by the first rotating rod 13. At this time, the first gear 14 rotates with the first rotating rod 13. Through the setting of the meshing of the first gear 14 and the second gear 19, the second rotating rod 18 can rotate in the opposite direction while the first rotating rod 13 rotates, so that the gauze 9 The first rack 21 is released by the second rotating rod 18, and when the second slide bar 8 moves to the left, the first rack 21 moves to the left together with the second slide bar 8. Through the setting of the first rack 21 meshing with the third gear 20, the third gear 20 can be rotated counterclockwise. Through the setting of the third gear 20 meshing with the second rack 22, the second rack 22 can drive the first slide bar 7 to slide to the right along the direction of the first slide groove 5, so that the gauze 9 can be unfolded following the first slide bar 7. Through the setting of the gauze 9 fixedly connected to the left side of the first slide bar 7, the top window opening structure of the greenhouse has the effect of preventing leaves and debris from entering the interior of the shed body 1 when the top window is opened.

[0027] Embodiment 2:

[0028] See also Figures 1 to 4 The utility model provides a technical solution: a top window opening structure of a greenhouse, the inner wall of the second slide groove 4 is slidably connected with a second slide bar 8, the left side of the second slide bar 8 is fixedly connected with a windshield cloth 10, the front of the second slide bar 8 is fixedly connected with a first rack 21, the first rack 21 is located on the outside of the shed body 1, the first rack 21 is located directly above the third gear 20 and meshes with the third gear 20, the first rack 21 and the second rack 22 are both arc-shaped, the first rack 21 is located at the top of the second slide bar 8, the second rack 22 is located at the bottom of the first slide bar 7, a first rotating rod 13 is provided on the left side of the windshield cloth 10, the first rotating rod 13 and the second rotating rod 18 are consistent in size and shape, the windshield cloth 10 and the gauze 9 are consistent in length and width, the shed body 1 is fixedly connected with a first fixed block 11 and a second fixed block 12 at the outer end thereof, the back of the first fixed block 11 is rotatably connected with the front of the first rotating rod 13, the front of the second fixed block 12 is rotatably connected with the back of the first rotating rod 13, the first rotating rod 13 and the second rotating rod 18 are symmetrical inside and outside the shed body 1, the first fixed block 11 is located on the back of the first rack 21, the outer end of the first rotating rod 13 is fixedly connected with a first gear 14, the first gear 14 and the second gear 19 are consistent in size and shape, the back of the first gear 14 is flush with the back of the first rotating rod 13, the first gear 14 is meshed with the second gear 19, the back of the second fixed block 12 is fixedly installed with a motor 15, and the motor 15 is transmission-connected with the first rotating rod 13.
