Abstract

The utility model discloses a double-layer vegetable shed, which comprises supporting pillars, an upper shed frame, a lower shed frame, an upper-layer covering, a power-driven rolling-tape shaft, a rolling-tape wheel, a rolling tape, a lower-layer covering and a lower-layer covering rolling stick. The double-layer vegetable shed adopts the upper-layer covering for fixing, enables the lower-layer covering to be in a replaceable type and a power-driven rolling type, is simple and convenient in replacement, and high in power-driven rolling efficiency. In use, the power-driven rolling-tape shaft lays down the rolling tape, and the curly lower-layer covering rolls downwards under the effect of gravity along an arc-shaped framework of a lower-layer shed frame and covers the whole lower shed frame. When not in use, the power-driven rolling-tape shaft collects the rolling tape and rolls up the lower-layer covering. In winter, the lower-layer covering which adopts anti-freezing thermal-insulating fabrics is laid down at night to form two-layer thermal insulation so as to prevent vegetables from being frozen. In summer, the lower-layer covering which adopts thermal-insulating shading fabrics can be laid down in the daytime when the sun shines violently so as to shade the vegetables from the sunlight and control the light.

Description

Double-deck green house of vegetables

Technical field

The utility model relates to agriculture green house of vegetables technical field, specifically is meant a kind of double-deck green house of vegetables that is used for planting vegetable and melon and fruit.

Background technology

The most single layer plastics films structures that adopt of present agriculture green house of vegetables, the defective of this structure is: winter, thermal property was poor, summer is heat insulation and shaded effect is poor, and external environmental factor is big to the shed vegetable growth effect, and the output of vegetables, quality and production cycle can not get guaranteeing.

The utility model content

For remedying above-mentioned defective, it is a kind of reasonable in design, easy to use that the utility model provides, and can be used for the warming heat insulation double-deck green house of vegetables of shading in summer that can be used for again in winter, is used to solve the warming and heat insulation problem of shading in summer in winter of green house of vegetables.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: design a kind of green house of vegetables that uses double-deck overcover, comprise support column, go up frame, frame, upper strata overcover, electronic take-up spool, tape feed roller, winding, lower floor's overcover and lower floor's overcover rolling rod down, described support column, go up frame, frame is a centrosymmetric structure down;

Described upper strata overcover is a transparent plastic film;

Described electronic take-up spool with bearing fixing between last frame and following frame, the center of two support columns;

Described electronic take-up spool and green house of vegetables are isometric;

On the described electronic take-up spool tape feed roller is housed;

On the described tape feed roller winding is housed;

The center of the tape feed roller that described winding one end is fixing and on tape feed roller;

The described winding other end is walked around the intersection point next door that web-like lower floor overcover is fixed on down frame and support column;

On overcover coiling lower floor of the described lower floor overcover rolling rod;

Described lower floor overcover adopts the two volume symmetrical structures of both sides to middle rolling;

Described lower floor overcover places down the top of frame;

The symmetrical centre edge of described lower floor overcover is fixed on the top of frame down;

Described lower floor overcover is an anti-freezing and heat-insulating cloth;

Described lower floor overcover is heat insulation gobo.

Owing to adopted above-mentioned structure, the utility model adopts the upper strata overcover to fix, and lower floor's overcover is a changeable type and electronic wrap-up, change simple and convenient, electronic rolling efficient height.During use, electronic take-up spool puts down winding, and lower floor's overcover of web-like rolls downwards along the arc skeleton of lower floor's frame under the effect of gravity, covers whole frame down.When not needing to use, electronic spool of tape is packed up winding, and lower floor's overcover rolling rod arc skeleton along lower floor's frame under the effect of winding scrolls up, and rolls lower floor's overcover and stops when contacting support column.During winter, lower floor's overcover uses anti-freezing and heat-insulating cloth, and pack up daytime, allows sunlight inject and makes intensification in the canopy, and in order to vegetable growth, put down evening, forms double-layer heat insulation, prevents the vegetables frostbite.During summer, lower floor's overcover uses heat insulation gobo, puts down when daytime, the sun was fierce, covers sunlight, control illumination, and pack up evening, allows space enlargement in the canopy, is convenient to heat radiation.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 rolls frame partial top view at present for lower floor of the present utility model overcover;

Fig. 3 is a web-like of the present utility model lower floor overcover sectional view.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail, as depicted in figs. 1 and 2, double-deck green house of vegetables described in the utility model, comprise support column 1, go up frame 2, frame 3 down, between last frame 2 and following frame 3, the center of two support columns 1 is with the electronic take-up spool 4 of bearing fixing.Two tape feed rollers 5 are equipped with at the two ends of electronic take-up spool 4 respectively, and tape feed roller 5 of every end is responsible for respectively lower floor's overcover 7 is on one side carried out rolling.Center, the other end that one end of winding 6 is fixed on tape feed roller 5 are fixed on down by the intersection point of frame 3 and support column 1, and length is rolled near till the ground with the arc skeleton that can partly embrace down frame 3 under layer overcover 7 edges.Lower floor's overcover 7 be cut into earlier than the whole arc skeleton of following frame 4 long slightly after, two ends are separately fixed on lower floor's overcover rolling rod 8, another side is counterclockwise clockwise on one side then rolls respectively to middle rolling, the center is fixed on down the top of frame 3, it is fixed that the web-like part is drawn by 6 half armfuls of shapes of two winding, spreads upper strata overcover 9 at last.The gate of the connection of electronic take-up spool and transmission, frame both sides and the part that does not relate to are used technique known, repeat no more.

When being used for the preventing freeze in winter insulation, lower floor's overcover 7 uses anti-freezing and heat-insulating cloth, start electronic take-up spool 4 evening and loosen winding 6, web-like lower floor overcover 7 is rolled into downwards near ending on ground along the arc skeleton of following frame 3 under the effect of gravity, the weight tension lower floor overcover 7 of lower floor's overcover rolling rod 8 is close to the arc skeleton of frame 3 down, form heat-insulation layer, prevent the vegetables frostbite.The electronic take-up spool 4 that reverses daytime is packed up winding 6, and lower floor's overcover rolling rod 8 arc skeleton along lower floor's frame 3 under the effect of winding 6 scrolls up, and stops when rolling lower floor's overcover 7 to contact support column 1, allows sunlight inject, in order to vegetable growth.

When being used for summer heat insulation shading, lower floor's overcover 7 is replaced by heat insulation gobo, puts down when daytime, the sun was fierce, covers sunlight, and the gate of opening the frame both sides in case of necessity ventilates, and pack up evening, allows space enlargement in the canopy, is convenient to heat radiation.

Be to increase the sealing property of junction, lower floor's overcover 7 adopts the overlapping formulas to hide, and a top that is placed on down frame 3 in after the rolling is as Fig. 2.
