Description

A kind of vegetable growing plastic tunnel

Technical field

The utility model relates to a kind of vegetable growing plastic tunnel.

Background technology

China is vast in territory, and the weather complexity utilizes plastic tunnel to carry out the facility cultivations of vegetables, flowers etc., and the disparities between supply and demand of alleviating vegetables dull seasons have been played special important function, has the huge economic benefit of remarkable social benefit and reality.Plastic tunnel makes full use of solar energy, heat up obviously, wall after the thickening, reduce cultivation face, heat-insulation and heat-preservation and situation that measure such as manually heat is complete under, can utilize plastic tunnel to cultivate in the northern area of China throughout the year.

Coating steel pipe assembled booth is comparatively advanced at present booth version.The big-canopy framework of this modular construction, its arch bar, longitudinal tie, termination column are thin-wall steel tube, and be connected to form integral body with special mould clamp, all rod members and jig all adopt the antirust processing of galvanizing, be the industrial products that batch production is produced, formed the multiple series of products of standard, standard, and had special use to roll up the film ventilation with accessory film-coiling device or volume film machine.

The flat-top shading shed is the special facilities of cultivation of shading, the southern area (comprising the middle and lower reach of Yangtze River and South China) of China's autumn in summer long term high light, high temperature use more.Constitute by drag-line skeleton and sunshade net draw curtain system.Can be according to the requirement of the climatic condition of locality and institute raise crop, the sunshade net that select suitable specification, the rate of shading is suitable to illumination.Manual or the electronic curtain-drawing device that the draw curtain system adopts specialized factory to produce, closed or unlatching sunshade net that can be quick and easy.It highly is a 3-4 rice, and 7 meters * 6 meters of elementary cells are a unit with 28 meters * 24 meters generally, can be in flakes wider, and its effect is better.Holder film distance between centers of tracks 0.5-0.6 rice, film-pressing line spacing 1-1.2 rice.

Being used in combination of coating steel pipe assembled booth and flat-top shading shed can realize the bidirectional temp regulation function preferably, but at China's southern area, particularly Hunan area, the overcast and rainy low temperature of winter-spring season, no sunlight,

Can not heat in the material booth; Summer and autumn are hot and humid, and sick worm harm is serious, the plant growth difficulty.The booth that area such as domestic northeast, North China, northwest, Hainan is suitable for, in south particularly under the special climate condition of Hunan area availability low, applicable surface is little; Though external green house automaticity height, cost and operation cost costliness, and the actual conditions of domestic agricultural production require cultivating facility to have lower construction cost and operation cost.So existing apparatus is difficult to satisfy the particularly requirement of Hunan area of south, cause the booth vegetable cultivation phase short, production efficiency is low, and vegetable supply is light, the busy season has a long way to go.

The utility model content

In order to solve above-mentioned drawback, technical problem to be solved in the utility model is, a kind of vegetable growing plastic tunnel that Hunan area is used that is suitable for is provided, and has stronger two-way adjustment ability, has lower construction cost and operation cost simultaneously.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is, a kind of vegetable growing plastic tunnel, comprise coating steel pipe assembled booth and the flat-top shading shed that is installed on booth ceiling top, it is characterized in that, described booth ceiling is the Continuous building type structure that is formed by connecting by a plurality of arc frames, and the two ends of described arc frame are towards North and South direction, and low north, south, arc frame top is high; Two arc frame junctions are provided with rain-harvesting trough, and rain-harvesting trough one end is provided with downpipe, and each arc frame is installed at least one skylight and switching device thereof; But described booth body of wall is by insect protected yarn internal layer and the outer double-decker of forming of rolling film, and film-coiling device is located at the booth outside corner of wall; Described booth east wall device cooling cascade and water circle device thereof, western wall device negative-pressure air fan; Described booth Nan Qiang and the some vent windows of north wall device, Nan Qiang also are provided with door and insect protected Gauze portiere thereof; Described flat-top shading shed is made up of several sunshade net splicings, and each described arc frame correspondence is provided with a width of cloth sunshade net, and every width of cloth sunshade net draws in or expansion along east-west direction, and its curling position is at the middle position of each arc frame; Ground in the described booth is provided with some hot water circuit pipelines that have radiating fin.

The utility model is described in further detail below in conjunction with embodiment.

Description of drawings

Fig. 1 is the main TV structure figure of the utility model specific embodiment, has embodied simultaneously manually and the skylight gear of electronic two kinds of structures;

Fig. 2 is the plan structure figure of the utility model specific embodiment;

Fig. 3 is the left TV structure figure of the utility model specific embodiment.

Embodiment

Referring to accompanying drawing, reflect a kind of concrete structure of the present utility model, 30 meters long from south to north of described vegetable growing plastic tunnel, long 40 meters of thing.Comprise coating steel pipe assembled booth and the flat-top shading shed that is installed on booth ceiling top, described booth ceiling is the Continuous building type structure that is formed by connecting by a plurality of arc frames 5, two arc frames, 5 junctions are provided with rain-harvesting trough 14, as a kind of preferred, described rain-harvesting trough 14 adopts detachable structure, when summer high temperature, pull down rain-harvesting trough 14, can play aeration-cooling effect.Rain-harvesting trough 14 1 ends are provided with downpipe 36, each arc frame skylight 12 of 5 installings and switching device thereof.

Because hot-air can rise, for the climbing power of utilizing this kind to form naturally forms air exhaust passage, to realize the aeration-cooling of no operation cost, the booth ceiling should have the hot-air that certain gradient is convenient to rise to escape into outside the canopy; Need to consider many south winds in summer of cooling simultaneously, hot-air is discharged direction should select the north, so the two ends of described arc frame are towards North and South direction, and low north, south, arc frame top is high, as the more excellent a kind of selection of its gradient design, its gradient is between 0.7-1.4%.
