Film greenhouse for a bed

The utility model relates to agriculture, namely to growing plants in sheltered soil under a transparent film.

Known film tunnel type greenhouses containing a frame installed in the supports made of arcuate pipes with a film coating stretched over them according to the patents of the Russian Federation No. 20112196 (publ. 15.05.94), No. 20133933 (publ. 15.06.94) and autosvid. USSR No. 1344282 (publ. 15.10.87).

These greenhouses can be manufactured in a modification where the worker is located inside the greenhouse, as in the greenhouses described in utility models of the Russian Federation No. 8208, publ. 11.16.98 and No. 8207, publ. 11/16/98.

With a decrease in size, these tunnel greenhouses can be used to shelter individual beds, while the worker is located outside the greenhouse.

The main disadvantage when using the above structures for sheltering the beds is the excessive complexity and excessive metal consumption of the structure. When reducing the size of the greenhouse, it becomes important to ventilate a small volume of the greenhouse, and in these structures it is either not provided or is imperfect.

Known protective device according to the utility model of the Russian Federation No. 21126 (publ. 04/05/2001), containing a conical shape of a transparent shell and elements of thermoregulation and humidification. This device can be transported assembled and quickly installed on the ground. : The purpose of creating the proposed utility model is to optimize the design so that the greenhouse for beds is easy to carry, quickly installed in place, with ventilation and humidification elements using a minimum of materials, with a low manufacturing cost. This goal is achieved by the fact that in a greenhouse containing a translucent film coating, supporting arches, thermoregulation and humidification elements, the power frame consists of a convex arched closed from the ends of the tunnel. wire arcs that are installed outside or inside the film frame and along the entire length of the arcs are attached to the film, while the ends of the arcs are stuck into the ground and have a limit stop, and the upper part of the two end arcs is connected by stretch marks to the rings driven in in the ground, the end parts of the film coating have ventilation holes, and a vessel with water, having capillary holes, is dug in the soil of the beds. The advantage of the proposed model over the well-known tunnel-type greenhouses is due to the fact that in it the supporting arches provide stability only in the transverse direction, and therefore can have a smaller cross section. In the longitudinal direction, the stability of the greenhouse is ensured by two extensions stretching the film frame. In the prototype there are no stretch marks, and the film does not form a power frame, it only hangs on arcs. In the proposed design, only wire and film are used, there are no fasteners. This makes the design easier and cheaper. If a thin film is used, then to strengthen the structure, the upper points of all arcs are connected by a cord. The film frame is non-separable, can be made by welding pieces of film, it easily folds into a bag along with "

At a distance of, for example, 15 cm from the ends of the arcs, there is a restrictive stop on them. If D5ta is made of wire, then the emphasis can be formed, for example, by local rotation of it around the rod. This ring de-energizes equally the height of the installation of all arcs above the bed, since the ends of all arcs are plunged into the ground to the same depth. The same ring is used when attaching the ends of the arcs to the fence of the garden, if any.

The connection of the arc and the film coating can be achieved by making a chain of holes in the surface and pulling the wire arc through the holes, while the wire sequentially enters and leaves the greenhouse. In this case, one of the support rings is made after connecting the arc to the film. In another embodiment, strips of film (fabric) are welded (glued) to the film at the edges, which are loops by which the film is attracted to the arc. In the loops between the film and

the wire has heat-insulating spacers to protect the film from stretching when the film is heated by sunlight.

For arcs, other flexible arched elements can be used, for example, rods made of plastic or tubes of small diameters made of plastic or metal.

In the end parts of the tunnel film coating of the greenhouse there are ventilation holes, at one end in the upper part, at the other in the lower part of the end. When the air overheats in the greenhouse, light hot air can escape through the upper small openings if there is a flow of colder air into the greenhouse, which is ensured by the presence of openings in

bottom of the butt. The upper holes are covered from the outside of the greenhouse

squares from the film, welded to the film coating with two edges. A valve is formed that can release air in the gap between the coating film and the welded edge of the square, and the wind cannot

penetrate these holes. This protects the film from rupture at the holes and from blowing cold wind into the greenhouse.

The bottom vent is designed to represent

It is a long slotted channel that externally approaches the end of the greenhouse, the lower wall of which forms the surface of the earth, and the upper wall is formed by a film horizontally stretched above the surface of the earth. This design provides cooling in the gap near the ground of the air entering the greenhouse during hot weather and provides heating from the ground entering the greenhouse: the air is 0-time-freeze & - because the frost is warmer than atmospheric air. These effects are amplified if the slot channel is buried in the ground.

A vessel with water is dug into the soil along the greenhouse beds, which is a hose with capillary holes connected to a vessel by a water tank. Both the hose and the vessels can, for example, be made of two halves of welded film preforms, and are filled with, for example, nylon washcloths to give a three-dimensional shape.

A vessel filled with water, returning water through capillary holes, for several days provides the necessary soil moisture in the garden. When freezing, cold air, passing in the slotted channel above the vessel with water, is heated. If there is no water in the vessel, then air goes into the greenhouse through the vessel and the vessel performs the function of a slot channel.

The drawing shows a diagram of the proposed film greenhouses for beds. By means of welded strips of film 2, wire arcs 3 are fastened to the translucent film coating 1, stuck into the ground to the restrictive ring 4. The end support arcs are connected by braces 5 to the rings 6, stuck into the ground. There is a ventilating inlet slot channel 7 and outlet vents 8. A vessel 9 with water is dug in the soil of the bed.

The proposed greenhouse contains the minimum number of structural elements and materials, can be compactly packed, quickly installed on the garden bed, provides ventilation in the heat and protects plants from small (-3 ° С) short-term (several hours) frosts, increases the temperature in the greenhouse several degrees higher outdoor, which allows you to use the bed a month earlier than in open ground.
