The utility model provides an automatic ventilation
greenhouse, and belongs to the technical field of planting greenhouses. Comprising a supporting frame, a
greenhouse is arranged outside the supporting frame, a double-end motor is fixedly installed inside the supporting frame, a winding
assembly is arranged at one output end of the double-end motor, the winding
assembly comprises a winding wheel, a winding
rope is arranged on the surface of the winding wheel, a film winding
assembly is connected to one end of the winding
rope, and the other end of the winding
rope is connected with a film storage assembly. A rolling film is arranged on the surface of the
greenhouse, and one side of the rolling film is connected with the film rolling assembly. The device has the advantages that the abutting wheel extrudes the first
swash plate and the second
swash plate to
complete linkage, the first
swash plate rotates to drive the abutting wheel to rotate so as to drive the second swash plate to rotate, collision is not prone to occurring during connection in the mode that the abutting wheel extrudes the first swash plate and the second swash plate, abrasion can be greatly reduced, and the situation that the service life of the winding assembly is shortened is avoided; frequent maintenance is not needed, and the practicability is high.
