Description

A kind of greenhouse rolling blind device

Technical field

The present invention relates to field of agricultural production technologies, be specifically related to the roller blind device of a kind of booth.

Background technology

Warmhouse booth, also known as greenhouse, printing opacity, insulation, is used to the facility of cultivated plant.In the season being not suitable for plant growing Joint, is provided that greenhouse period of duration and increases yield, be used for the plant cultures such as low temperature season warm season vegetable, flowers, forest or educate Seedling etc..For sunshade on daytime, being incubated night, more advanced warmhouse booth is typically provided roller blind device for hiding to plastic house Screened postive or heat-insulation layer.Existing roller blind device is normally located at the top of booth, covers material and is crimped onto on a roll shaft, logical Cross the rotation folding and unfolding cover layer of roll shaft.The roller blind device of this structure requires that covering material to have stronger stretch-proof and coiling-resistant energy Power, and because there is extruding and the reason such as scratching and can not be answered in some intensity differences but good heat insulating and cheap light material With, which greatly enhances production cost.Simultaneously as the defect in structure, the roller blind device of existing structure can not be at same volume Laying the insulation material of wider amplitude on axle, many set spools use, and the seam between heat-insulation layer can affect the effect of insulation.

Summary of the invention

The technical problem to be solved is: for the problems referred to above, it is provided that the greenhouse rolling blind of a kind of more reasonable structure Device.

The technical solution of the present invention is: a kind of greenhouse rolling blind device, including cover layer, roll shaft, roller and rope, roller Axle is arranged on described cover layer place of process in lifting process, and roll shaft two ends are fixed on the periphery of booth by support, rolling Rope that wheel forms a circle for stretching also limits rope along the axial displacement of roller, and rope is wound on roll shaft and roller and surrounds one Circle, and "the" shape bending is formed in the southern side of booth, it is peripheral that some circle ropes are trapped among booth by roll shaft and roller, described Cover layer wraps in outside booth and is fixed on rope, is rotated by drive roller shaft and rope can be driven to lift cover layer.

The solution have the advantages that: it has that reasonable in design, cost be low, easy to use and economy and durability excellent Point.With rope as carrier, cover layer pulls lifting, centre not to contact with miscellaneous part by rope, the problem that there is not scratch. Cover layer all the time will not be by rope and roll shaft extrusion damage in the outside of rope.Pulling force does not act directly on cover layer, to covering The not requirement of cap rock intensity, cover layer can be lighter, more cheap.Cover layer can be combined into one, and centre does not has seam, protects Temp effect is more preferable.The application on roll shaft of the prestressing force rope, the spanning length that can make roll shaft is bigger, it is possible to reduce use or not Use intermediate support, to the simplification of structure advantageously.

Accompanying drawing explanation

Fig. 1 is the structural representation of the present invention；

Fig. 2 is the structural representation of roll shaft of the present invention.

Detailed description of the invention

As illustrated in fig. 1 and 2, a kind of greenhouse rolling blind device, including cover layer 1, roll shaft 2, roller 3 and rope 4, roll shaft 2 sets Putting in described cover layer 1 place of process in lifting process, roll shaft 2 two ends are fixed on the periphery of booth 6, rolling by support 5 Ropes 4 that wheel 3 forms a circle for stretching also limit rope 4 along the axial displacement of roller 3, and rope 4 is wound on roll shaft 2 and roller 3 On form a circle, and form "the" shape bending in the southern side of booth 6, some circle ropes 4 are trapped among by roll shaft 2 and roller 3 Booth 6 is peripheral, and described cover layer 1 wraps in outside booth 6 and is fixed on rope 4, is rotated by drive roller shaft 2 and can drive rope 4 lifting cover layers 1.

Described booth 6 is provided with the underground pore 7 of its south and north flanks through in ground, and the two ends of underground pore 7 are provided with roller 3, described rope 4 through underground pore 7 and is wound on roll shaft 2 and roller 3.

Described roll shaft 2 is made up of prestressed cable 8, central siphon 9 and bearing 10, and the two ends of prestressed cable 8 are separately fixed at support 5 On, central siphon 9 is enclosed within prestressed cable 8, and the end of central siphon 9 is provided with bearing 10, and the bearing 10 wherein contacted with support 5 uses thrust Bearing, is strained by prestressed cable 8 and is clamped between two stands 5 by central siphon 9.

Described central siphon 9 is multistage.

General booth length is longer, and roll shaft length then can add support, waist phenomenon of collapsing in order to prevent roll shaft from occurring in centre. And the gap location that can never contact with cover layer at the position that "the" shape is overlapping adds " L " shape support so that it is not with covering Layer directly contact.Use prestressed cable can reduce as shaft core or the most do not use the support of centre, being greatly simplified structure, subtract Few production cost.Can suitably increase some reinforcement structures as netted bottom cover layer to be connected with the rope being trapped among on booth. Heat preservation greenhouse typically uses in the south and end face is transparent, and arranges thermal-insulation masonry wall on north, and cover layer only need to cover the south at booth Face and end face.The not used time, cover layer is moved booth north to by rope and is deposited in the position that the "the" shape of rope is overlapping. Underground pore can be preset in Foundation Part, can use the material pipe being difficult to corrosion.Roller shutter power can use manpower or driven by power, The roll shaft being wherein positioned at bottom is relatively big with rope contact face, can add driving wheel and use as drive shaft on pipe.Can also It is separately provided drive shaft, drives with the winding of rope large area by arranging driving wheel thereon.
