Film greenhouse

 

The invention relates to agriculture and can be used to shelter the plants when they are growing. Film greenhouse contains a skeleton made of sections, each of which is formed by two curved pipes stretched film surface, means for fixing between the pipes, supports and face the floor. Film coating is made in the form of a continuous sleeve, with the formation of two-layer coating. Inside the cover are curved pipe and a self-expanding struts, made in the form of spring-loaded tubular locking tension. The means for fixing is made in the form of removable tubes that are installed on the curved pipe, and attached to them self-expanding struts. Section of the frame is formed by alternating at least two modules, the first of which is made with a radius smaller diameter arcuate tube relative to the second module, the set overlap relative to the first. This implementation provides constant tension film coating when the temperature drops. When heated to a second module with a large corner radius increases the overlap by the amount of stretching of the cover. When the provides reduced labor costs, improving the durability of the greenhouse, simplifying and reducing the cost of its installation, dismantling and operation. 2 C.p. f-crystals, 4 Il.

The invention relates to agriculture and can be used to shelter the plants when they are growing.

Famous film greenhouse, containing a skeleton made of sections formed with two bent tubes with strained on them bag a film covering, support, made of rods with pointed ends, end cover and cords located between the films of the sleeve and see.with. The USSR 1344283, CL IPC7A 01 G 9/14, publ. 15.10.87).

The disadvantages of this design are a multi-stage Assembly, the complexity of manufacturing, low life, the need for special film coating.

Closest to the claimed technical solution is film greenhouse, containing a skeleton made of sections, each of which is formed by two curved pipes stretched film surface, means for fixing between the pipes, supports and end cover (see RF patent 2012196, IPC7A 01 G 9/14, publ. 15.05.94).

The disadvantages of the prototype is a multi-stage installation, the complexity, there is predlagaemogo of the invention is to reduce labor costs, improving the durability of the greenhouse, simplifying and reducing the cost of installation, dismantling and operation.

The technical result is to reduce mnogostadiinost Assembly and disassembly, ease of schema ventilation and simplifying operation.

This technical result is achieved by the fact that known in the polytunnel, containing a skeleton made of sections, each of which is formed by two curved pipes stretched film surface, means for fixing between the pipes, supports and end coating film according to the invention the coating is performed in the form of a continuous sleeve, with the formation of two-layer coating, inside of which are curved pipe and a self-expanding struts, made in the form of spring-loaded tubular locking tension, and means for fixing is made in the form of removable tubes that are installed on the curved pipe and attached to them self-expanding struts, moreover, the partition frame formed by alternating at least two modules, the first of which is made with a radius smaller diameter arcuate tube relative to the second module, the set overlap relative to the first is UCAV. End coating can be deaf and/or with doors, mounted in a solid film sleeve. Plug in modules placed with a shift relative to the axis of curved pipes, and in the first module, they offset set inside the greenhouse, and the second out.

This design greenhouses can reduce labor intensity, labor costs, improve durability by a two-layer coating and the absence of acute friction fasteners.

The essence of the design of the greenhouse is illustrated by drawings, where Fig.1 shows a General view of the greenhouse of Fig.2 is a fragment of connection modules in a checkerboard pattern of Fig. 3 - fragment tension film coating of one module relative to another, in Fig.4 - design of self-expanding struts.

The construction of the film greenhouses consists of a frame made of at least two alternating modules 1 and 2, each of which is formed by two curved pipes 3 and self-expanding struts 4 and the film coating is made in the form of a continuous sleeve 5, inside of which are curved pipe 3 and the self-expanding struts 4.

The frame is provided with end cover 6 made in the form of a continuous sleeve, inside the cat to be muted and/or provided with a door 8, located in a continuous film sleeve 6 (see Fig.1).

Means for fixing between a pipe consists of a removable tube 9 mounted on the curved pipe 3, and fixed on her self-expanding struts 4 (see Fig.2).

Self-expanding strut 4 is a split tube, inside which is located the locking tube 10, with one end rigidly fixed mounting element 11 and the other end of the tube abuts against the spring 12, rigidly fixed on the opposite end to the split pipe 4 (see Fig.4).

Detachable pipe 4 is equipped with a fixed latch 13, a movable detent 14 and the hole 15 for the rolling retainer 14.

Film greenhouse is assembled as follows.

The Assembly and installation of greenhouses produce on-site maintenance. First, collect the solid module 1 frame. Restilt solid film sleeve 5 along the length of 10-15% greater than the length of the curved pipe 3 and introduce two pipes inside the sleeve 5, there also introduce self-expanding struts 4 spring loaded retainer 14 condition. Then the latch 14 is removed from the holes 15 and self-expanding strut 4 comes in a stretched state, pulling in this great film sleeve 5 with education is the EPR curved pipe 3.

In module 1 fixed end cover 6, which is made hollow and/or door 8, and is fixed to the ground, for example, pegs or sprinkled earth.

Modules 1 and 2 have interleaved in a checkerboard pattern, and module 2 set overlap on the module 1 with smaller radii of curvature of curved pipes 3.

When heated film coating module 2 increases the overlap on the amount of stretch film coating 5 that it eliminates sagging, but at a lower temperature film coating 5 is shortened to a fixed value using the tabs 13, 14 and spring 12.

For ventilation module 2 is moved relative to the modules 1 (right or left) or raise the land above the ground and fix it, for example, props.

Tube 9 is made with an offset from the axes of the curved pipe 3 in modules 1 inside the greenhouse, and in modules 2 to the outside. Installing modules 1 and 2 with an offset in the tubes 9 centres achieved the tight pressing of the film coating 5 and eliminates the gap between the modules 1, 2 (see Fig.2).

The use of the proposed film greenhouses compared to the prototype will reduce the complexity of Assembly, installation and operation, labor costs, and increase n the e cost of the greenhouse.
