Problems solved by technology

The above-mentioned technical solution improves the utilization rate of land, but the automatic roll-up mechanism is set outside the room temperature shed, the heat preservation effect is not good, and the load-bearing of the greenhouse skeleton is increased, which is easy to cause the risk of collapse; the east and west side walls occupy a lot of land and have serious shading

Embodiment Construction

[0018] see figure 1 , the present embodiment is a three-span energy-saving solar greenhouse, which is formed by connecting three single-slope greenhouses with different spans, different heights, and different horizontal planting surfaces, and the interior is a connected whole. It includes a rear wall 1, a column 5, a ridge wall 9, and an arc-shaped skeleton 2 supported and fixed by the back wall 1, the column 5, and the ridge wall 9. The lower end of the arc-shaped skeleton 2 is provided with a support frame 8, An electric thermal insulation quilt 3 is provided on the support frame 8; a plastic shed film is covered on the arc-shaped frame 2 and the east and west sides of the solar greenhouse; an electric air outlet is provided on the front roof or the rear roof 4 of the solar greenhouse 7.

[0019] The planting surfaces 10 of the first building and the second solar greenhouse are respectively lower than the ground level, which is not only beneficial for heat preservation, but...

Abstract

The invention discloses a multi-span energy-saving sunlight greenhouse, which is formed by more than two greenhouses in a connecting way and consists of a rear wall, stand columns, a sleeper wall and arc-shaped skeletons which are jointly and fixedly supported by the rear wall, the stand columns and the sleeper wall. A supporting frame is arranged at the lower end of the arc-shaped skeleton. An electric heat preserving quilt is arranged on the supporting frame. The arc-shaped skeleton and the east side and the west side of the sunlight greenhouse are covered by plastic greenhouse films. Electric air vents are arranged on the front roof and/or the rear roof of the sunlight greenhouse. The multi-span energy-saving sunlight greenhouse overcomes the defect that the multi-span plastic single-film greenhouse or the multi-span greenhouse cannot be covered by nontransparent heat-preserving materials at present. Compared with the multi-span greenhouse, the interior temperature in low-temperature seasons is obviously improved, the annual service cycle is increased by two to three months and the greenhouse is a novel and unique multi-span energy-saving sunlight greenhouse.

Description

technical field [0001] The invention belongs to the technical field of agricultural facilities, in particular to a multi-span energy-saving solar greenhouse, which is suitable for large-scale planting of various vegetables. Background technique [0002] At present, most of the greenhouses in the main vegetable producing areas in northern my country are single-span solar greenhouses with small planting scales, mostly 400m 2 ~600m 2 , and the back wall and the east and west gables occupy a lot of land and the shading is serious, the land between the greenhouses is seriously wasted, the land utilization rate is low, and the degree of indoor equipment is low, the space is small, the environmental control ability is poor, the output is low, the quality is poor, and the production low efficiency. The traditional single-span solar greenhouse is covered with heavy straw curtains, which is labor-intensive; during long-term use of the straw curtain blanket, the dust affects the ligh...
