[0027] The two second fixed plates 16 are respectively fixedly connected to the inner side of the ventilation frame 1 and the left blocking frame 12. The two second fixed plates 16 are respectively provided with two fan groups 17. The two fan groups 17 are symmetrically arranged and connected to each other through a transmission belt. The hot air inside the greenhouse can enter the right side area of ​​the dividing plate 19 in the ventilation frame 1 through the two exhaust frames 4 and be transported upward, so that the hot air flow drives the right fan group 17 to rotate. The right fan group 17 drives the left fan group 17 through the transmission belt to transport the air entering the ventilation frame 1 through the partition net 6 downward. In this way, the air transported by the left fan group 17 can be transported to the two air outlet frames 5 and diffused to the left, thereby replacing and ventilating the air inside the greenhouse, and increasing the sufficient air oxygen content required for mushroom cultivation.

[0028] The left blocking frame 12 is fixedly connected to the first fixed plate 15, and the two blocking frames 12 are respectively fixedly connected to the first connecting plate 13 and the second connecting plate 18, and the opposite sides of the first connecting plate 13 and the first fixed plate 15 and the opposite sides of the second connecting plate 18 and the second fixed plate 16 are fixedly connected with two elastic members 14.

[0029] The front and rear sides of the ventilation frame 1 are fixedly connected with an exhaust frame 4 and an outlet frame 5. The two exhaust frames 4 are arranged in a right-angled U-shape with an opening at the bottom. The two exhaust frames 4 are communicated with the right side of the partition plate 19 on the ventilation frame 1. The two outlet frames 5 are arranged in a right-angled U-shape with an opening on the left side. The two outlet frames 5 are communicated with the left side of the partition plate 19 on the ventilation frame 1.

[0030] The outer peripheral side of the ventilation frame 1 is fixedly connected to the mounting frame 7, and the outer periphery of the ventilation frame 1 is sleeved with the film frame 8, so that the mounting frame 7 can be located above the film, so that the film frame 8 can be slid up to clamp the film with the mounting frame 7 and be fastened with screws.

[0031] The support assembly 2 includes two sliding plates 21, both of which are fixedly connected to the bottom surface of the ventilation frame 1, and the two sliding plates 21 are fixedly connected to the lifting plate 22.

The lower end of the first screw rod 23 is fixedly connected to a first hand wheel. By rotating the first hand wheel, the first hand wheel drives the first screw rod 23 on the support assembly 2 to rotate, so that the first screw rod 23 pushes the lifting plate 22 upward under the support of the stabilizing plate 24. At the same time, the lifting plate 22 drives the two sliding plates 21 to synchronously push the ventilation frame 1 upward and insert and socket into the opening opened on the top surface of the greenhouse film for fixation.

[0032] The stabilizing plate 24 is fixedly connected to the upper ends between the two hole plates 25, the two hole plates 25 are respectively connected to the two sliding plates 21, the bottom surfaces of the two hole plates 25 are respectively fixedly connected to the two bottom plates 26, a reinforcing plate 27 is fixedly connected between the two bottom plates 26, and two sockets are provided on the two bottom plates 26, which can be connected to the bottom surface of the greenhouse through pins, thereby improving the supporting and stabilizing effect of the supporting assembly 2.

[0033] The adjusting component 3 includes a first push-pull plate 31, which is set to an N-shape. The first push-pull plate 31 is fixedly connected to a second push-pull plate 32 which is set to an L-shape. The second push-pull plate 32 is threadedly connected to a second screw rod 33. The upper end of the second screw rod 33 is rotatably connected to the bottom surface of the ventilation frame 1 through a bearing. The lower end of the second screw rod 33 is fixedly connected to a second hand wheel. By rotating the second hand wheel, the second hand wheel drives the second screw rod 33 on the adjusting component 3 to rotate. The second screw rod 33 pulls the second push-pull plate 32 downward under the support of the bottom surface of the ventilation frame 1. At the same time, the second push-pull plate 32 drives the first push-pull plate 31 to move downward synchronously. In this way, the first push-pull plate 31 and the second push-pull plate 32 can drive the two blocking frames 12 to slide downward along the card frame plate 11. In this way, the two blocking frames 12 can slide down to expand the ventilation area of ​​the partition net 6, which is convenient for automatic air output and suction replacement.

[0034] The two side plates of the first pushing plate 31 and the vertical side plates of the second pushing plate 32 are respectively socketed with the three rectangular holes opened on the bottom surface of the ventilation frame 1, the two side plates of the first pushing plate 31 are respectively fixedly connected to the front and rear ends of the bottom of the right blocking frame 12, and the vertical side plates of the second pushing plate 32 are fixedly connected to the second connecting plate 18.

[0035] The two side plates of the first push-pull plate 31 are vertically distributed with the second fixed plate 16 on the right side and staggered with the fan group 17 on the right side, so that when the first push-pull plate 31 pulls the blocking frame 12 up and down to move, it will not be blocked or restricted by the second fixed plate 16 and the fan group 17 on the right side, thereby facilitating the adjustment of the air volume.

[0036] The operating steps of the utility model are:

[0037] By rotating the first hand wheel, the first hand wheel drives the first screw rod 23 on the support assembly 2 to rotate, so that the first screw rod 23 pushes the lifting plate 22 to move up under the support of the stabilizing plate 24, and at the same time, the lifting plate 22 drives the two sliding plates 21 to synchronously push the ventilation frame 1 to move up and insert and sleeve into the opening opened on the top surface of the greenhouse film, and make the installation frame 7 located above the film, so that the slidable film frame 8 slides up and clamps the film with the installation frame 7 and is fastened with screws;

[0038] The second hand wheel is then turned, and the second hand wheel drives the second screw rod 33 on the adjusting assembly 3 to rotate. The second screw rod 33 pulls the second push-pull plate 32 downward under the support of the bottom surface of the ventilation frame 1, and at the same time, the second push-pull plate 32 drives the first push-pull plate 31 to move downward synchronously, so that the first push-pull plate 31 and the second push-pull plate 32 can drive the two blocking frames 12 to slide downward along the card frame plate 11, so that the two blocking frames 12 can slide down to expand the ventilation area of ​​the partition net 6, so that the hot air inside the greenhouse can enter the right side area of ​​the dividing plate 19 in the ventilation frame 1 through the two exhaust frames 4 and be transported upward, so that the hot air flow drives the right fan group 17 to rotate, and the right fan group 17 drives the left fan group 17 through the transmission belt to transport the air entering the ventilation frame 1 through the partition net 6 downward, so that the air transported by the left fan group 17 can be transported to the two air outlet frames 5 and diffused to the left, thereby replacing and ventilating the air inside the greenhouse, and increasing the sufficient air oxygen content required for mushroom cultivation.
