Abstract
The utility model relates to a fast ventilating device for hothouse greenhouses. The utility model comprises a moving greenhouse film, a bracket is under the moving greenhouse film, the bracket is provided with a rolling cylinder which is provided with a main pull rope, the main pull rope bypasses a pulley forming a closed loop, the main pull rope is provided with a plurality of positioning rings and a plurality of auxiliary pull ropes which penetrates through the positioning rings, the both ends of the utility model are fixed on the main pull rope, and the middle of the utility model is fixed on a rope on the edge of the moving greenhouse film. The utility model has the advantages that the ventilating speed of the utility model is high, every ventilating operation only needs several seconds, the utility model reduces the labor strength of vegetable growers and prevent the greenhouse films from being damaged by manual ventilation, and the opening width of a ventilating belt can be adjusted at any time for satisfying different requirements of greenhouse ventilation.
Description
The green house that the utility model the relates to a kind of agricultural cultivation device that leaks informaton fast.
Along with the continuous development of China's rural economy, the range of application of greenhouse plastic tunnel constantly enlarges, and it is more and more general that the canopy colza is implanted in the northern area of China, has become the pillar industry of northern area rural economy.
Because the greenhouse plastic tunnel is subject to the influence of ambient temperature, and, the planting density height in the canopy, the dispensing concentration of agricultural chemicals and fertilizer is big, therefore, and stuffy in the plastic tunnel, temperature and humidity changes greatly, in order to guarantee the normal growth of plant, just must carry out ventilation at any time.In the prior art, the normally ventilation band with the booth equal length of device that leaks informaton of greenhouse plastic tunnel, be that the booth covering plastic thin film arrives from about chi of cob wall, form one one opening that how wide chi is on the cob wall limit, on this opening, re-lay a mobile canopy film, and,, prevent to damage to increase its intensity at rope of the edge of booth plastic film and mobile canopy film parcel.This device that leaks informaton can only adopt manual operations, when leaking informaton, need fasten with rope again with manually with sectional the pushing aside of mobile canopy film, when closing, need earlier rope to be untied, more mobile canopy film is covered piecemeal, operating is numerous rope, time-consuming again, in the ordinary course of things, the operation of leaking informaton of each greenhouse plastic tunnel approximately needs about 1.5 hours every day, has taken a large amount of time of people.In addition, the labour intensity of the operation of leaking informaton is also very big, not easy to operate, because the cob wall of green house is very narrow, also is placed with above and covers curtain with mat, will lie prone during operation and carry out covering with mat on the curtain, runs out of space.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the plastic tunnel band that leaks informaton in existing greenhouse is improved, and a kind of green house device that leaks informaton fast is provided.
The utility model is achieved in that
It has a mobile canopy film, a support is arranged below mobile canopy film, reel is housed on the support, main stay cord is housed on the reel, main stay cord is walked around pulley, form closed circuit, several locating rings and some secondary stay cords are housed on main stay cord, and secondary stay cord passes locating ring, and its two ends are fixed on the main stay cord, center fixed drives mobile canopy film motion on the rope of mobile canopy film edge.
The utility model compared with prior art has following advantage:
1, the speed of leaking informaton is fast, and the operation of at every turn leaking informaton only needs several seconds, can save about 1.5 hours of the operating time of leaking informaton every day, uses eight months in 1 year, then can save the 360 hours time of leaking informaton every year, and the vegetable grower is freed from the operation of leaking informaton.
2, simple in structure, with low cost, easy to use, processing ease when reducing vegetable grower's labour intensity significantly, has also been avoided manual and has been leaked informaton to the damage of canopy film, and the width that the band that leaks informaton is opened can be adjusted at any time, has satisfied the different requirements that booth leaks informaton.
3, secondary stay cord is horizontal is pulled on the mobile canopy film, and mobile canopy film can not be blown up, and has avoided the damage of mobile canopy film, has prolonged the service life of mobile canopy film.
The drawing explanation:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is that the B of Fig. 1 is to view.
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in drawings, the utility model has a mobile canopy film 12, mobile canopy film 12 is with by leaking informaton between cob wall and booth plastic film 11, a limit of mobile canopy film 12 is enclosed on the cob wall, another edge lap is on the booth plastic film, and scalable moving, in order to strengthen resistance to tension, also wrap up a rope at its edge; A support 6 is arranged below mobile canopy film 12, two symmetrically arranged bearing blocks 7 are arranged on the support 6, on the bearing block 7 of support 6 reel 10 is housed, reel 10 usefulness bearing glands 9 are installed on the bearing block 7, in bearing block 7 and bearing gland 9, sliding bearing 8 is housed also, to reduce mechanical wear; Also rolling bearing can be installed at this place, its effect is identical; Handwheel 5 is equipped with at two ends at reel 10 respectively, rotates so that drive reel 10; Reel 10 also can be connected with speed reduction gearing with electromotor, adopts electronic mode to realize forward and reverse rotation of reel 10; Main stay cord 2 is housed on reel 10, and the two ends of main stay cord 2 are separately fixed on the reel 10, and twine a few according to different directions on reel 10; Main stay cord 2 is walked around 4 pulleys 1, forms the loop of a closure; Several locating rings 3 are housed on main stay cord 2, and 3 two of locating rings are one group, and are staggered relatively, and are fixed on the skeleton of booth, and main stay cord 2 passes through in locating ring 3; Some secondary stay cords 4 also are housed on main stay cord 2, and secondary stay cord 4 is provided with one every about 3 meters, and secondary stay cord 4 passes locating ring 3, and its two ends are fixed on the main stay cord 2, and center fixed is on the rope at mobile canopy film 12 edges
When reel 10 rotates, main stay cord 2 one ends on the reel 10 twine, one end is decontroled, main stay cord 2 moves on pulley 1, and secondary stay cord 4 movement therewith when main stay cord 2 moves must be walked around locating ring 3 when secondary stay cord 4 moves, because the position of locating ring 3 is fixed, therefore, secondary stay cord 4 just can drive mobile canopy film 12 motions when moving, reach the purpose that opens and closes the band that leaks informaton.
