Double-layer type intelligent siamese plastic arched greenhouse for agricultural production

Abstract

The invention relates to a double-layer type intelligent siamese plastic arched greenhouse for agricultural production. The plastic arched greenhouse comprises an outer-layer arched shed, an inner-layer arched shed, a door wall, a skeleton, an access door, cross beams, longitudinal beams, a plurality of skeleton supporting columns, eye splices, plugging bolts, a coating plastic film, stabilizing frames, a light transmission layer, heat insulating cotton, a heat insulating layer, a heating furnace, firm columns and a ventilating duct, wherein the outer-layer arched shed consists of the skeleton and the coating plastic film covering the outside surface of the skeleton, the plurality of skeleton supporting columns which are upright in a spaced manner are separately arranged at the two ends of the side face of the skeleton, the longitudinal beams are arranged at top ends of the skeleton supporting columns, the cross beams corresponding to the skeleton supporting columns are arranged at middle areas of the longitudinal beams, the door wall is arranged at one side of the outer-layer arched shed, the access door is arranged at the bottom end of the door wall, the inner-layer arched shed is arranged inside the outer-layer arched shed, a ventilating device is arranged at the top of the plastic arched greenhouse, an automated humidity control system is arranged at the rear side of the internal part of the plastic arched greenhouse, the heating furnace is arranged at the middle side of the internal part of the plastic arched greenhouse, and seedling-raising seedling beds and vegetable seedling raising cabinets are separately arranged at the left and right sides of the internal part of the plastic arched greenhouse. The double-layer type intelligent siamese plastic arched greenhouse for agricultural production has the advantages that the service time of the arched greenhouse can be prolonged, the internal humidity of the greenhouse is effectively controlled, the disassembly and assembly are quick, and the structural strength is high.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a double-layer intelligent conjoined plastic shed used in agricultural production. Background technique [0002] With the emergence of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. In the early 1950s, Japan, European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small sheds and greenhouses with good results. my country introduced polyvinyl chloride agricultural film in the autumn of 1955. It was first used to cover vegetables in small sheds in Beijing, and achieved the effect of early maturity and increased production. The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. At present, greenhouses have been used for potted flower and cut fl...

Problems solved by technology

However, after analysis, it is found that the existing heating furnaces used for greenhouses in the low temperature period have the following deficiencies; one: the heat loss of soil heating furnaces is relatively slow, and it is difficult to dissipate heat into the greenhouses in a short period of time; second: it cannot be controlled The heating time of the heating furnace; third: it is troublesome to add fuel

[0005] After searching, it is found that the invention of application number 201410324745.3 discloses a greenhouse shed. After analysis, it is found that the existing one-piece plastic shed has the following deficiencies; first: high humidity and high turbidity after long-term use; Limitations; Third: It takes time and effort to build and disassemble, and the structure is not stable enough

[0006] After retrieval, it was found that the utility model patent No. 201620791991.4 disclosed a vegetable greenhouse automation system. After analysis, it was found that the existing vegetable greenhouse humidity automation control system had the following deficiencies; Two: The light transmission in the shed cannot be guaranteed

[0007] After searching, it is found that the utility model of patent No. CN205912521U discloses a kind of seedling bed. After analysis, it is found that the existing seedling bed has the following deficiencies; one: the hole tray is directly placed on the surface of the land, which increases the probability of soil disease transmission of vegetable seedlings , brought diseases to vegetable growers and seedling factories; second: the materials used are relatively expensive, which strengthens the burden on small and medium seedling factories; third: and the existing seedbeds are a waste of water resources, which cannot meet the requirements of water saving

[0008] After searching, it is found that the utility model of patent No. CN201919422U discloses a vegetable seedling cabinet. After analysis, it is found that the existing vegetable seedling cabinet has the following deficiencies; one: lack of heating and heat preservation devices; Carry out multi-layer cultivation; third: lack of red and blue light needed for plant growth; fourth: unable to understand the temperature and humidity in the nursery cabinet
