Abstract
The utility model relates to a ground heating system for a vegetable greenhouse, in particular to a solar hot air soil heating vegetable greenhouse. The solar hot air soil heating vegetable greenhouse comprises a greenhouse, air conveying pipes, a heating coil pipe and an induced draft fan, wherein the heating coil pipe is buried in soil, and two ends of the heating coil pipe are connected with the air conveying pipes respectively; heat-preserving films are arranged on two sides of a ridge of soil; the induced draft fan is connected on one air conveying pipe; an induced air opening and an air outlet which are communicated with the air conveying pipes are formed in the greenhouse; and the heating coil pipe is a polyethylene (PEX) crosslinking pipe which is arranged in a shape like a Chinese character 'hui'. According to the solar hot air soil heating vegetable greenhouse, hot air flows in the heating coil pipe by a circulating system, so that heat is transferred in modes of radiation and heat conduction to fulfill the aim of heating the soil; and the heat-preserving films are arranged on two sides of a ridge of soil to prevent the heat loss of the soil, so that the yield of vegetables is improved. The solar hot air soil heating vegetable greenhouse is reasonable in structural design, wide in application range and low in cost.
Description
Technical field
The utility model relates to the green house of vegetables ground heating system, particularly relates to a kind of solar energy hot blast soil heating vegetable greenhouse.
Background technology
China's most area winter severe cold and very long in the Winter-Spring cold season that crops can't grow, is greatly developed booth vegetable production and is the inevitable course.By building all kinds of green houses, solved the vegetables consumption problem of part Winter-Spring cold season.Along with improving constantly of people's living standard, annual winter vegetable quantity is very large.The analysis of causes is, mainly is that sunlight is not enough because winter climate is cold, and facilities horticulture production is very restricted.Wherein, the problem that soil temperature is lower fails effectively to be solved always.No matter be greenhouse by solar heat or traditional greenhouse of heating, soil temperature is by after the raising room temperature, indirectly improve ground temperature, because soil heat conductivity is little, therefore soil temperature improves few, effectively to the short leaf vegetables of rhizome like this, but bad to the long melon-fruit-like vegetable effect of rhizome.Present winter greenhouse booth, the majority leaf vegetables of also can only growing is produced fruit and vegetable and also must be improved soil temperature and could realize.Room temperature in the booth is to heat by sunshine, the thermal source additional heat such as recycling stove or radiator will be heated in the canopy, although take above measure, also can only make in the greenhouse temperature reach (cloudy day) about 12 ℃ daytime, about 6 ℃ of nights, (10～20cm) generally only have about 9 ℃ soil temperature in the canopy, canopy is interior under such environmental temperature, only can satisfy the growth needs of some leaf vegetabless, can't reach the temperature requirement that the fruit vegetables normal growth is grown, winter, temperature of irrigation water generally only had about 4 ℃, so the excessively low problem of rear indoor ground temperature of watering, become the bottleneck that restriction fruit vegetables in winter is grown.The root system degree of depth of various crops is different with the requirement to temperature and soil temperature, generally has between 11-40 ℃.
Based on this, the utility model is proposed.
The utility model content
For solving the above-mentioned technical problem of prior art, the utility model provides a kind of solar energy hot blast soil heating vegetable greenhouse, its reasonable in design, applied widely, cost is low, by the circulatory system hot-air is flowed in heat(ing) coil, heat with radiation and heat-conducting mode transmission, is reached the purpose that soil is heated, in the both sides of a ridge soil insulation film is arranged, prevent that soil heat runs off, thereby improve yield of vegetables.
For achieving the above object, solar energy hot blast soil heating vegetable greenhouse of the present utility model is achieved through the following technical solutions:
A kind of solar energy hot blast soil heating vegetable greenhouse, comprise booth, also comprise air-introduced machine, heat(ing) coil, the first wind conveying pipe and the second wind conveying pipe, described booth is provided with air-vent and air outlet, be connected with air-introduced machine on the first wind conveying pipe, and its two ends are communicated with air-vent and heat(ing) coil input respectively, the second wind conveying pipe two ends are communicated with air outlet and heat(ing) coil output respectively, described heat(ing) coil is embedded under the soil, and the both sides of a ridge soil are provided with insulation film.
Described heat(ing) coil is the heat(ing) coil that hollow is arranged.
Described heat(ing) coil is the PEX cross-linking tube.
The beneficial effects of the utility model are as follows:
Solar energy hot blast soil heating vegetable greenhouse of the present utility model flows hot-air by the circulatory system in heat(ing) coil, with heat with radiation and heat-conducting mode transmission, reach the purpose that soil is heated, there is insulation film both sides at a ridge soil, prevent that soil heat runs off, thereby the raising yield of vegetables, its reasonable in design, applied widely and cost is low.
Description of drawings
