Description

Double-layer four-season greenhouse

Technical Field

The utility model relates to the technical field of agriculture, concretely relates to double-deck four seasons greenhouse.

Background

The greenhouse is a major breakthrough in agricultural technology, improves the growth environment of crops, accelerates the growth of crops, and shortens the growth cycle. The method is widely applied to various crops such as seedling breeding, vegetable planting, fruit tree cultivation, bud seedling cultivation and the like.

The common greenhouse is simple in structure, applicable to regions which are not too cold, such as the regions south of the North China, but the northeast and the inner Mongolia are difficult to produce in the greenhouse in cold periods, and the greenhouse can be started after severe cold, so that vegetables can only enter the greenhouse in the local area during the period, and the greenhouse is high in cost and high in price. In northeast China, especially in Heilongjiang and northern inner Mongolia, if agricultural production is required all year round, a greenhouse which can ensure normal agricultural production in winter especially in cold is required.

In order to solve the problems, a plurality of double-film double-arch greenhouses exist at present, and the specific structures of the double-film double-arch greenhouses mainly comprise two types: one is a double-layer greenhouse with walls. The structure is that the east-west wall and the rear wall are built by hard wall buildings such as masonry, rammed earth, polystyrene board and the like and heat insulation materials, and a small ventilation window is left in the rear wall, and some rear walls do not exist; the front roof adopts a heat preservation mode of double films, double arches (frameworks) and double quilts; the back roofing can not lift and roll up for the vast majority. The other is a wall-free and ground-inserting type double-layer greenhouse. The structure is that the east-west wall and the rear wall are built by a profile steel framework, a heat preservation quilt, a soft wall building and heat preservation materials, and the rear wall is not provided with a ventilation window; the front roof adopts a heat preservation mode of double membranes, double arches (frameworks) and double quilts, and the rear roof cannot be lifted and rolled up.

The common disadvantages of the two double-layer greenhouses are as follows:

firstly, the air release opening is not windproof. The orientation of the greenhouse is generally 5-8 degrees in the south and the west, and is the direction towards the air opening, and particularly in areas with more early spring and strong wind weather, the contradiction between 'air release' and 'wind prevention' cannot be solved. The air is not discharged, and the temperature in the greenhouse is high; and (5) releasing air, and tearing the plastic greenhouse film at the air opening by strong wind. In order to prevent strong wind from entering the shed from the 'wind release port', the 'release of a heat preservation quilt' is realized by film pressing instead of the prior art.

Secondly, the air outlet is not rainproof. The 'air release openings' of the two air release modes are not tightly closed, rain is leaked in heavy rain weather, a 'water pocket' is easily formed at the 'air release opening' position, a shed film is damaged by pressure, and three contradictions of 'air release', 'wind prevention' and 'rain prevention' cannot be solved in case of weather intermission of wind and rain.

Thirdly, after the heat preservation is rolled up to the roof, the heat preservation is parked in front of the ridge of the greenhouse, the front roof of the greenhouse is occupied, and the lighting area of the front roof is reduced.

Fourthly, the heat preservation quilt is parked in front of the shed ridge, a groove is formed between the shed ridge and the quilt roll, and although the rain-proof cloth is arranged below the heat preservation quilt roll, the problem of rain covering and water filling is serious. Particularly, the problem that the heat preservation quilt in the early winter and the early spring cannot be used for keeping rain and filling water in the rain or in the weather of rain and snow is solved; even if the difficulty of rain prevention is too large when the quilt is not used for heat preservation in summer, the labor and the time are wasted and the cost is high.

Fifthly, most of the heat preservation quilts on the rear slope of the greenhouse cannot be rolled up to lift, so that wind cannot be released in summer, and the growth of crops cannot be influenced when the temperature in the greenhouse is high; before and after summer, the sun reaches the return line of north, the rear roof of the greenhouse blocks light, and the requirement of crop growth at the horizontal projection position of the rear roof cannot be met. Although individual double-layer greenhouse back slope heat preservation quilts with walls can be rolled up and lifted, the quilt is not provided with an outer layer framework and a shed film to protect rain, and the heat preservation quilt is seriously filled with rain and filled with water.

Sixth, the protection of the outer layer framework of the back slope and the shed membrane is lacked, even if the front roof is a double-membrane double-arch (framework) double quilt, in a high-latitude cold area, the through-flow heat release of the roof in winter behind the greenhouse is more, the heat preservation effect is not ideal, and the temperature required by the growth of fruits and vegetables can not be met easily without heating.

Seventhly, because the two layers of frameworks of the existing double-layer greenhouse are provided with the greenhouse films, the sunlight penetrates through the two layers of greenhouse films to cause insufficient illumination intensity on plants in the greenhouse in winter, and the plants cannot obtain sufficient sunlight, which is also a problem discovered by the applicant after the two layers of greenhouse films are used.
