[0032] In order to make the purpose, technical solutions and advantages of the present invention more clear, the implementation methods of the present invention will be further described in detail below with reference to the accompanying drawings. Example

[0033] The utility model provides a ventilation device for vegetable planting greenhouses. Figure 1-3 , comprising a greenhouse main body 1, the greenhouse main body 1 is staggeredly covered with plastic film segments, and the plastic film segments are provided with through holes.

[0034] The greenhouse body 1 is staggeredly covered with a first plastic film segment 104 and a second plastic film segment 204, the first plastic film segment 104 is provided with first through holes 105 at equal intervals, and the second plastic film segment 204 is provided with second through holes 205 at equal intervals, and the first through holes 105 and the second through holes 205 on the adjacent first plastic film segments 104 and the second plastic film segments 204 are distributed on both sides of the greenhouse body 1, so that when one end of the first plastic film segment 104 having the first through hole 105 is released on the corresponding first rotating shaft 101, the other first rotating shaft 101 rolls up the first plastic film segment 104 (ensuring that the first plastic film segment 104 is taut), so that the first through hole 105 is located on the greenhouse body (i.e., the greenhouse steel frame), so that ventilation can be achieved by using the first through hole 105;

[0035] The first rotating shaft 101 , the first supporting column 102 , the first rotating disk 103 , the first plastic film segment 104 , and the first through hole 105 constitute a first covering assembly.

[0036] Both ends of the first plastic film segment 104 are respectively wrapped around the first rotating shaft 101, and both ends of the first rotating shaft 101 are rotatably connected to the first support column 102 through bearings. One end of the first rotating shaft 101 is fixedly connected to the first turntable 103, and the first turntable 103 must be heavy enough to avoid the influence of wind force causing the first plastic film segment 104 to drive the first rotating shaft 101 to rotate; the two first rotating shafts 101 are respectively located on both sides of the greenhouse body 1.

[0037] Both ends of the second plastic film segment 204 are respectively wound around the second rotating shaft 201, and both ends of the second rotating shaft 201 are rotatably connected to the second support column 202 through bearings. One end of the second rotating shaft 201 is fixedly connected to the second turntable 203. The second turntable 203 must be heavy enough to avoid the influence of wind and cause the second plastic film segment 204 to drive the second rotating shaft 201 to rotate. The two second rotating shafts 201 are respectively located on both sides of the greenhouse body 1; the second rotating shaft 201, the second support column 202, the second turntable 203, the second plastic film segment 204, and the second through hole 205 constitute a second covering component.

[0038] There is an overlap between the adjacent first plastic film segments 104 and second plastic film segments 204 , thereby ensuring sealing.

[0039] In specific use, when ventilation is needed, the first rotating shaft 101 close to the first plastic film segment 104 is driven to rotate, and the first plastic film segment 104 is released, and the other first rotating shaft 101 rolls up the first plastic film segment 104, so that the first plastic film segment 104 with the first through hole 105 partially covers the greenhouse body 1;

[0040] The second rotating shaft 201 close to the second plastic film segment 204 is driven to rotate, and the second plastic film segment 204 is released, and the other second rotating shaft 201 reels the second plastic film segment 204, so that the second plastic film segment 204 with the second through hole 205 partially covers the greenhouse body 1;

[0041] The first through hole 105 and the second through hole 205 are used to ventilate the interior of the greenhouse. Example

The first limiting rod 106 is pressed on the first plastic film segment 104 and is located close to the bottom of the greenhouse body 1, so as to ensure that the first plastic film segment 104 is in contact with the greenhouse body 1;

[0043] A first support connection seat 109 is welded on the first support column 102, and the first support rod 107 is inserted into the inner wall of the first support connection seat 109, and the first support rod 107 and the first support connection seat 109 are fixed by bolts;

[0044] A third support connection seat 108 is welded on the first limiting rod 106, and the inner wall of the third support connection seat 108 is inserted into the first support rod 107 and fixed to the first support rod 107 by bolts;

[0045] The second support columns 202 are each equipped with a second support rod 207, and a second limiting rod 206 is installed between the two second support rods 207; the second limiting rod 206 is pressed on the second plastic film segment 204 and is located close to the bottom of the greenhouse body 1, thereby ensuring that the second plastic film segment 204 fits the greenhouse body 1;

[0046] A second support connection seat 209 is welded on the second support column 202, and the second support rod 207 is inserted into the inner wall of the second support connection seat 209, and the second support rod 207 and the second support connection seat 209 are fixed by bolts;
