Description
Technical field
The present invention relates to greenhouse film dedusting technology field, be specifically related to a kind of daylight film for greenhouse dust collection method and device.
Background technology
Along with the continuous adjustment of China's structure of rural undertaking, the cultivated area that the cultivated area of facilities horticulture presents burgeoning trend, particularly facilities vegetable has in recent years accounted for more than 80% of the facilities horticulture gross area.The facility form that heliogreenhouse is created as China, its apply that area will account for all installations area 60 ~ 70%, the victual wherein produced, for the vegetable supply meeting people, plays a part very important.
At present, heliogreenhouse has good heat-insulating property because of it, and at agricultural planting, particularly the field such as growing vegetables and nursery is widely used, especially at spring, autumn, northern area that winter temperature is on the low side.The Surgery therapy of heliogreenhouse has been effectively prevented the loss of warm indoor night heat, for plant growth provides suitable temperature simultaneously.Plastic sheeting is the main non-transparent covering material of heliogreenhouse, size and the change of its light transmittance are very large on the impact of heliogreenhouse light heat environment, good film printing opacity can improve greatlyr the growth of crop in heliogreenhouse, provides sufficient luminous energy to the photosynthesis of crop.But, lighting surface canopy film be subject to the pollution of dust after transmitance can significantly reduce, have a strong impact on indoor photoenvironment, even affect the growth of crop, reduce yield and quality.Heliogreenhouse light heat environment is formed, and depends on the permeable solar radiation of lighting surface, and therefore the light transmittance of lighting surface canopy film is one of key parameter weighing sunlight greenhouse structure quality.The climatic characteristic of northern area is: spring, autumn, winter easily blow, often there is dust storm even airborne dust weather, the sandy soil that the lighting surface of heliogreenhouse is often come by wind or floating dust pollution, lighting surface thickens, unintelligible, reduce the light transmittance of lighting surface, plant in greenhouse is because can not get sufficient sunlight, and growth is restricted.At present, solve the pollution problem of heliogreenhouse film dust and have two methods: change film and adopt manual type to carry out dedusting to heliogreenhouse surface.Frequent replacing film cost is high, adopts manual type dedusting technology difficulty large and wastes time and energy.
Summary of the invention
Technical problem to be solved by this invention is: carry out dedusting and the frequent defect changed existing for canopy film for above-mentioned employing manual type to the surface of daylight film for greenhouse, providing a kind of does not need artificial, can carry out dedusting by heliogreenhouse original insulation quilt shutter power daylight film for greenhouse dust collection method and device.
For solving the problems of the technologies described above, technical scheme of the present invention is as follows:
Daylight film for greenhouse carries out a method for dedusting, comprising:
By shutter power, roll along with shutter or put down insulation quilt, completing the dedusting to greenhouse film.
A kind of daylight film for greenhouse dust arrester, with shutter with the use of, comprise connector, dust-removing rod, cylinder, sleeve, dust removing cloth, support roller; Wherein dust-removing rod is fixed in shutter rotating shaft by connector, and with shutter shaft parallel; On dust-removing rod, interval arranges multiple cylinder and sleeve successively, and dust-removing rod two ends are fixed with support roller, and dust removing cloth is fixed on sleeve.
Described connector makes dust-removing rod move up and down with shutter rotating shaft.
Described support roller is separately positioned on east, greenhouse, Western Hills wall.
Described cylinder is fixed on dust-removing rod, and its spacing designs according to Sunlight greenhouse frame distance, rolls on Keelof green house with dust-removing rod.
Described sleeve empty set, on dust-removing rod, moves up and down with the rolling of dust-removing rod but does not rotate.
Described daylight film for greenhouse dust arrester also comprises spacing preiection, makes connector fixing in shutter rotating shaft and dust-removing rod, prevents it from moving along its length.
Described daylight film for greenhouse dust arrester also comprises protective device at night.
Described night, protective device was the box of an opening, and be located at the front room Jiao Chu of heliogreenhouse, opening, towards greenhouse, tilts 20 ° ~ 40 ° with horizontal line.
Described dust removing cloth, according to heliogreenhouse surface profile vandyked, guarantees that dust removing cloth touches daylight film for greenhouse.
Beneficial effect of the present invention
1, method and apparatus of the present invention is by the power of heliogreenhouse insulation quilt structure of rolling, and every day carries out 2 dedustings to greenhouse film, without the need to additionaling power and energy consumption, and environmental protection and energy saving.
2, device of the present invention solves the amount of deflection problem of dust arrester by the mode of the branched point of cylinder, solves the restriction of dust arrester length, can be used for the heliogreenhouse of various length specification.
3, apparatus structure of the present invention is simple, and installation and debugging are convenient, dismountable at any time, and cost is low, easily promote.
4, the dedusting cloth of apparatus of the present invention can adopt the material that antistatic adsorbs to make, absorption and erasing dust successful.
