Description

Novel greenhouse, insulating quilt for greenhouse

One, affiliated technical field

The utility model relates to the outer covering and heat insulating product of a kind of agricultural greenhouse by solar heat, booth, and this product has good, easy to operate, the widely used characteristics of heat insulation effect.

Two, background technology

The quality of heat-insulating property directly influences the production status and the benefit of greenhouse, booth.At present, the masses generally adopt the straw screen or mat insulation in greenhouse by solar heat production, also there are indivedual areas to adopt multi-ply paper quilt, nonwoven and cotton-wadded quilt to be incubated, these products mostly Keep away from rain, be afraid of snow, be afraid of wind, heat-insulating property is not good, and quality heaviness, operation inconvenience, the investment that has is too big, and service life is shorter, so need a kind of easy to operate, good heat insulating, investment is less, service life is long again insulating product on the market badly.

In recent years, some insulating products (thermal insulation quilt) have also successively been manufactured experimently on ground such as Beijing, Shandong, and its properties of product have bigger improvement than straw screen or mat etc., but still exist heavy, the too big shortcomings such as (every square metre of 10-15 units) of operation inconvenience, investment.

Three, summary of the invention

(1) technical problem to be solved is in order to overcome the existing ubiquitous quality heaviness of outer covering and heat insulating product of greenhouse by solar heat, operation inconvenience, be afraid of wind, Keep away from rain, be afraid of snow, heat insulation effect is not ideal enough, investment is big, the shortcoming that service life is short, now the novel heat insulation of my invention is by just on the basis of using for reference forefathers' experience, select heat insulating material for use according to heat preservation principle, adopt advanced production technology to produce, it has wind resistance, anti-rain, anti-snow, good heat insulating, light weight, easy to operate, invest little, plurality of advantages such as service life is long, not only be suitable for the insulation of greenhouse by solar heat, but also may be used on the plastic tunnel, can greatly improve the greenhouse, the temperature condition that booth is produced.

(2) adopt the technical scheme of this product of technical scheme to be: this thermal insulation quilt has three layers of composition, covers to press by thermal contraction machine to form.The upper strata is agricultural plastic film (will have good anti-aging, freeze proof, crease-resistant folding endurance energy), the middle level is the plate foam (structure is loose more, the more little heat-insulating property of density good more) of 3-4 millimeters thick, and lower floor is that one deck has aluminizing of good reflective function or tinfoil paper film.For convenient retracted, cover film-pressing line of pressure every a segment distance (about 2 meters) at last, middle interlayer.Area size according to greenhouse, booth generally produces wide cut (10-16 rice), overlength (60-70 rice) specification, carries out whole the covering.

The heat preservation principle of this technical scheme institute foundation is: because this thermal insulation quilt is whole the covering, be difficult for being swept by wind, can prevent greenhouse, the inside and outside heat convection current of booth; Because interlayer structure is soft loose, can store in a large number not moving air, can prevent the outside conduction of heat; Because lower floor is silvery white reflective membrane, can stop canopy, indoor heat to external radiation, (according to the small size test, its heat insulation effect is than the high 5-8 of straw screen or mat ℃ so heat insulation effect is good.

In the product actual production, operation for convenience, and enhancing wind resistance, cover film-pressing line of pressure at last, middle interlayer every 2 meters, line length is 2-3 a times of thermal insulation quilt width, covers except that the centre and presses the part, and the two ends remainder can be used as the operation stay cord and uses, evening is when covering, thermal insulation quilt is stretched, and two ends are fixed on the iron wire ring that sets in advance, take off daytime by the time, one end of stay cord is unclamped, thermal insulation quilt is left behind along the slope, and withering naturally gets final product before being put into canopy on the ground, is light heat insulation material owing to what select for use, so 1-2 people can finish lid, take off task, and is easy to operate.

Above-mentionedly adopt that to take off by mode be to pull down the formula of putting of withering naturally that is put on the ground,, also can raise labour efficiency with machinery shop volume in the place that volume shop machine is being arranged.

In this production, can suitably increase and decrease the thickness of plate foam according to various places temperature difference, to adapt to the needs of production.Because the selected material of the design is plastic products, so Keep away from rain, snow invasion and attack, under bad weather, heat-insulating property is good especially, produces material and easily buys on market, so invest less (every square metre about 3-4.5 unit), and grow (8-10) service life.

On plastic tunnel was produced in the past, because the outer covering insulation material that the canopy film is not fit to outward, so heat-insulating property is bad, it is shorter to produce the service time of lasting, generally only limits to early spring, makes to shift to an earlier date, delay the usefulness of cultivation after autumn, productivity effect is not high, the novel heat insulation quilt that I invent is owing to light weight, and the whole covering of energy, so except that being suitable for greenhouse by solar heat, can also cover on the booth, improve the productivity effect of plastic tunnel greatly.

(3) the beneficial effect the beneficial effects of the utility model are: simple in structure, heat insulation effect is good, not only can be applied on the greenhouse by solar heat, can also be used as the outer covering insulation material of plastic tunnel, and easy to operate.

Four, description of drawings

Five, embodiment

This product structure is simple, and production technology is also uncomplicated, and agricultural plastic film, film-pressing line can be buied on market, the wide cut plate foam, and the wide cut reflective membrane can be tailor-made by specialized factory, only needs a wide cut far infrared thermal shrinking package machine (laminating machine) to get final product.

Laminating machine wide cut on the open market only is a 2-4 rice, only needs and the contact of package packing machine producer, and a tailor-made specially wide cut (general 10-16 rice) machine gets final product.

When this product tool is not produced, plate foam (2) is spread out, earlier place film-pressing lines (4) every 2 meters thereon, cover compression molding material film (1) and reflective membrane at upper and lower faces simultaneously by laminating machine then and (3).
