Abstract
The utility model discloses a film rolling device used for plastic greenhouse for ventilating. In the utility model, a speed reducer is fixed on the front end of a cantilever arm, a film rolling shaft is connected with the output shaft of the speed reducer by a shaft connecting joint, and a positioning rod is connected with the shaft of the cantilever arm by a shaft hole on the back end of the cantilever arm. The utility model can conveniently and synchronously roll up the lap of a greenhouse film and roll a vent opening above a greenhouse ground foot skirt film, the ventilating opening is canonical and regular, and the greenhouse film is not easy to damage. The utility model has the advantages of simple structure and flexible and convenient use, the utility model realizes hand operating device opening ventilation and is favorable to control temperature in a greenhouse, and the utility model is a novel and special appliance for greenhouses for ventilating.
Description
The utility model relates to a kind of retracting device, and the film rolling device of a kind of plastic greenhouse ventilation usefulness of saying so more specifically is applicable to the cool-down dehumidification of plastic greenhouse.
Plastic greenhouse has obtained in the rural area using widely, has greatly promoted development of rural economy, and for adapting to the growth of crops in plastic greenhouse, the temperature and humidity in the booth must be done frequent adjusting.And at present, the ventilation of green house, people all directly scroll up with the hand bottom with the canopy film piecemeal, volume exposes the opening of a ventilation above the booth foundation skirt film, be beneficial to flowing of the interior air of canopy, reach the purpose of cooling, dehumidifying, but its labour intensity ventilation orifice big, that the canopy film bottom exposes is lack of standardization neatly, the canopy film is fragile, makes people feel very inconvenience.
The purpose of this utility model provides a kind of film rolling device of plastic greenhouse ventilation usefulness, it not only can be rolled the canopy film bottom easily synchronously, volume exposes the opening of a ventilation above the green house foundation skirt film, and the ventilation orifice standard is neat, the canopy film is not fragile.
The purpose of this utility model is achieved in that it comprises the reductor that is made of worm gear, worm screw, it is characterized in that reductor is fixed on the front end of cantilever, and film rolling rob is connected with the output shaft of reductor by shaft coupling; Locating shaft is coupling by the axis hole and the cantilever of cantilever rear end.
The utility model not only can be rolled the canopy film bottom easily synchronously, and volume exposes the opening of a ventilation above the green house foundation skirt film, and the ventilation orifice standard is neat, make the canopy film not fragile.Having characteristics simple in structure, flexible and convenient to use, realized that the armstrong's patent opening ventilates, help the control of temperature and humidity in the green house, is a kind of novelty and the green house ventilation unit that shows unique characteristics.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a concrete structure schematic diagram of the present utility model.
Fig. 2 is to use state diagram.
In Fig. 1-2, cantilever 2 usefulness have the steel plate of certain intensity to make, and worm reduction gear 3 is screwed the front end at cantilever 2, and the output shaft 4 of reductor 3 is vertical mutually with cantilever 2.Film rolling rob 6 is that a kind of diameter is four minutes steel pipe, grows 90 meters, and the left end of film rolling rob 6 is connected with the output shaft 4 of reductor 3 by shaft coupling.Rear end at cantilever 2 also is provided with axis hole; Locating shaft 1 is a kind of threaded shank, and locating shaft 1 is coupling by the axis hole and the cantilever 2 of cantilever 2 rear ends.
During use, cantilever 2 is fixed on the hard gable 7 in green house left side by locating shaft 1 or is fixed on the bracing frame on ground, the base of canopy film 10 bottoms cements on the film rolling rob 6, above canopy film 10, also be provided with the head-rope 11 of tractive film rolling rob 6, the upper end of head-rope 11 is directly tied up solid on film-pressing line, and head-rope 11 is fixed on the film rolling rob 6 simultaneously on the base of the lower end and canopy film 10 bottoms.When the greenhouse must lower the temperature, shake the handle 5 on reductor 3 power shafts, the output shaft 4 of reductor 3 rotates synchronously, output shaft 4 drives film rolling rob 6 and rotates, head-rope 11 and furling on the film rolling rob 6 that canopy film 10 bottoms blow slowly simultaneously, film rolling rob 6 winding volume film 10 is that radius, locating shaft 1 are to move on the arc of the center of circle along head-rope 11 with cantilever 2 simultaneously, under the effect of reductor 3 auto-lock functions, canopy film 10 bottoms are rolled up above green house foundation skirt film 8 expose that a straight ventilation orifice 9 is used for ventilating, dehumidifying.When need were closed ventilation orifice 9, back rotated the wind 5 on reductor 3 power shafts, ventilation orifice 9 can be closed to close.
