For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] The following will describe the present utility model in detail with reference to the drawings.

[0022] Refer to Figures 1-5 , a greenhouse which is convenient for ventilation, includes a greenhouse main body 1. A plurality of ventilation openings 2 are provided on both sides of the greenhouse main body 1 along the length direction. A frame 3 is fixedly enclosed around the outer edge of each ventilation opening 2 of the greenhouse main body 1. A rotating shaft 4 is rotatably connected inside each frame 3. A cover plate 5 for covering the frame 3 is fixedly sleeved on the rotating shaft 4. Two adjacent rotating shafts 4 penetrate through the frame 3 and are concentrically fixed with a linkage shaft 6. A support seat 7 is fixedly provided on the front side of the greenhouse main body 1. One side of the support seat 7 is rotatably connected with a transmission shaft 8. The transmission shaft 8 is concentrically fixed with the rotating shaft 4 at the forefront. A worm gear 9 is fixedly provided on the transmission shaft 8. The other side of the support seat 7 is rotatably connected with a worm 10 meshing with the worm gear 9. The lower end of the worm 10 is fixedly connected with a driving motor 11.

[0023] An expansion link 12 is arranged inside the frame 3. The fixed end of the expansion link 12 is rotationally matched with the inner wall of the frame 3, and the telescopic end of the expansion link 12 is rotationally matched with the inner side of the cover plate 5. The expansion link 12 expands and contracts in cooperation with the rotation of the cover plate 5 to maintain the connection with the cover plate 5, and can provide more stable support for the cover plate 5 after it is unfolded.

[0024] A limiting block 13 is fixedly provided on the inner wall of the frame 3. The limiting block 13 is used to abut against the inner side of the cover plate 5 to limit the rotation amplitude of the cover plate 5. When the cover plate 5 rotates and abuts against the limiting block 13, the cover plate 5 is in a vertical state and just covers the ventilation opening 2 at this time and cannot continue to rotate, making the position of the cover plate 5 after rotation more accurate.

[0025] A first magnetic strip 14 is embedded in the limit block 13, and a second magnetic strip 15 is embedded at the corresponding position of the cover plate 5. The second magnetic strip 15 is magnetically adsorbed to the first magnetic strip 14. By providing the first magnetic strip 14 and the second magnetic strip 15, the stability after the cover plate 5 is closed is increased.

[0026] A housing is fixedly provided on the support base 7. The worm gear 9, the worm 10, and the drive motor 11 are all located inside the housing, which is used to protect the worm gear 9, the worm 10, and the drive motor 11 components, maintain their good transmission effect, reduce the loss caused by the external environment, and extend the service life.

[0027] Working principle: When the greenhouse needs to be opened for ventilation, the drive motor 11 is started. The drive motor 11 drives the worm 10 to rotate. The worm 10 drives the transmission shaft 8 to rotate through the meshing worm gear 9, and then drives the rotating shaft 4 to rotate. The rotating shaft 4 rotates synchronously as a whole through the linkage shaft 6, and then drives a plurality of cover plates 5 to rotate synchronously. When the cover plates 5 are unfolded outward, the ventilation openings 2 are opened, and the greenhouse can be ventilated quickly, greatly reducing the labor intensity of manual film rolling and improving the efficiency of operating the ventilation of the greenhouse.

[0028] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. Any technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
