Manual curtain-drawing device

Technical field

The utility model relates to a kind of manual curtain-drawing device, mainly is applicable to the inside and outside draw curtain of small size agricultural facility.

Background technology

Along with greatly developing of China's efficient industrial agricultural, the promotion efficiency of agricultural facility also strengthens year by year again.The various corollary systems of agricultural facility are also perfect day by day, and draw curtain (sunshade) system is one of supporting as agricultural facility, has been widely used in each production greenhouse, thinks that crop provides rational illumination and temperature, ensure the growing environment that crop is suitable.Be exactly specifically, play the effect of insulation winter, play the effect of sunshading and temperature reducing summer.At present, domestic greenhouse main form that adopts in the draw curtain system has: steel wire rope draw curtain system, rack-and-pinion draw curtain system, wherein rack-and-pinion draw curtain system divides two kinds of " A " type draw curtain and " B " type draw curtains again.Above-mentioned several draw curtain mode be present conventional attached-greenhouse the draw curtain form that generally adopts, they all are applicable to large-area type of production or commercial type greenhouse, the general area that is suitable for is all more than 2000 square metres, and need to be equipped with special-purpose reducing motor (2000～3000 yuan/platform), adopt 380 volts of power drives.Also to be equipped with other auxiliary equipment that matches with reductor simultaneously.And along with the raising of Chinese economic development and people's living standard, land resources is in short supply day by day, and urban land is particularly nervous.Limited soil space will be utilized more fully.People begin more and more to advocate small size, leisure type, family type greenhouse, and general design is on roof, balcony, villa side or the like.The area in this leisure type greenhouse is generally at tens square meters or tens square meters, and maximum also is no more than 100 square meters.In the face of this leisure type small size greenhouse,, must cause the waste of resource and the inharmonious increase of cost if we still take traditional draw curtain (sunshade) mode.

Summary of the invention

The purpose of this utility model provide a kind of simple, economical, with manually operated small size agricultural facility curtain-drawing device, by this device, people can easily realize the unlatching of curtain materials such as sunshade net, nonwoven, fly net like a cork and cover, reach the purpose of sunshade, insulation and the insect protected of agricultural facility.

Comprise in order to reach the technical scheme that the purpose of this utility model takes, the curtain that has fixed edge and active edges, driving shaft 4, be provided with assembly pulley 7 on the both sides of curtain, stride across the steel wire rope 6 of assembly pulley 7, the two ends of steel wire rope 6 oppositely are wrapped on the driving shaft 4, and the active edges of curtain and steel wire rope 6 are connected, it is characterized in that, the film-coiling device 2 of a band handle has been installed at an end of driving shaft 4.

In the above-mentioned manual curtain-drawing device, one or more screen driving sheets 12 are housed on the active edges of curtain, this screen driving sheet is forked, and its prong is towards curtain.

In the above-mentioned manual curtain-drawing device, junction in steel wire rope 6 and the active edges of curtain is provided with a guide card 15 and two fixing cards 14, the bottom of guide card 15 is with the active edges that is horizontally through, its top is with 6, two 14 on the fixing cards of steel wire rope that vertically pass and is fixed on the steel wire rope 6 at guide card 15 two ends.

In the above-mentioned manual curtain-drawing device, film-coiling device 2 inside comprise one group of intermeshing change-speed gearing.

The utility model has overcome the defective that traditional draw curtain must rely on electric reducer, only needs simple manual operation on some minor installations, can finish the unlatching of curtain and covers.Owing to do not need electric reducer and electric energy, significantly reduced cost of investment, also saved the energy.This device using method is flexible, easy for installation, is a kind of very economical, effective curtain-drawing device.

Description of drawings

Fig. 1 is the stereochemical structure assembling schematic diagram of the manual curtain-drawing device of the utility model.

Specific embodiment

The utility model is elaborated by embodiment below in conjunction with accompanying drawing.

As shown in Figure 1,1 is the film-coiling device handle, artificial moment inlet, 2 is film-coiling device, and 3 is the connector of film-coiling device and driving shaft, and 4 is driving shaft, being used for lay winding

wire ropes

6,5 is the driving shaft bearing, is used for fixing driving shaft 4, it is fixing to carry out 360 degree rotations around the axle center, and 6 is steel wire rope, transmits pulling force, 7 is assembly pulley, in the present embodiment, 3 pulleys is arranged, be used for orientation and turn to, 8 is shade supporting wire, and 9 is the little black folders of plastics, be used for fixing curtain, 10 are the fixing stainless steel wire of curtain fixed edge, are used with little black folder, and 11 is curtain, in the present embodiment, this curtain is for sewing aluminium platinum internal sunshade net, and in actual production, it can also be the thermal-insulating type curtain, fly net etc., 12 is screen driving sheet, be used to draw in the curtain after closing, 13 is the curtain active edges, is used for fixing curtain and by steel wire rope 6 pulling motions, 14 is wire rope clamps, be used for fixing steel wire rope 6 and guide card, 15 is guide card, is used for curtain active edges and steel wire rope 6 are coupled together.

Manual moment passes to film-coiling device 2 by film-coiling device handle 1, film-coiling device 2 links to each other with driving shaft 4 by connector 3, in film-coiling device 2, moment is increased the back and pass to steel wire rope 6 by driving shaft by gear graduation, moment transfers pulling force to after by assembly pulley 7 break-ins and affects active edges 13, and active edges 13 will be sewed aluminium platinum internal sunshade net 11 by guide card 15 and wire rope clamps 14 and be drawn and open.Otherwise already, curtain is closed.
