Description
Technical field
The utility model relates to cultivation field, refers in particular to a kind of automatic mosquito-proof vent of piggery.
Background technology
First wild boar is tamed in China, and the history that China raises pigs can trace back to morning at the Neolithic Age, mid-term.The inscriptions on bones or tortoise shells that Qin period is unearthed according to Yin Dynasty ruins is recorded, and business, Zhou Shidai have the drylot feeding of pig.Then along with the development of producing, create the requirement distinguished different pigs gradually, in business, Zhou Shidai pig raising technology one large creation has invented hog technology.Han dynasty, along with the development of agricultural production, is raised pigs not only in order to edible, is also collected manure.This situation facilitates the change of the mode of raising pigs.Though existing drylot feeding before Han dynasty, until during Han dynasty only, herd and be still main mode of raising pigs.The physiological function of known pig and the relation of external form in the qualification of pig kind at that time, this plays great role early Medieval China this period in period to the excellent pig kind of Han dynasty seed selection, and drylot feeding is main feeding manner with herding that the feeding manner combined instead of to herd gradually.Along with the development of pig industry and the continuous progress of economic civilization, the experience of raising pigs becomes increasingly abundant.Raise pigs when Tang and Song Dynasty time Sui, Tang and become a kind of important means of peasant's additional income.There is a lot of creation in the Yuan Ming Yuan Dynasty in period in expansion pig feed source.Ming Dynasty mid-term, pig industry once suffered seriously to wreck, positive moral 14 years (1519), and because of " pig " and Ming Dynasty emperor Zhu surname unisonance, prohibited by order and support, between the ten days, distance is killed to the greatest extent, have then reduce the price low-priced sell or buried abandon.But the thing duration of prohibiting pig is not long, in pig raising technology as obtained some breakthrough achievements in pig variety discriminating and raising method etc.; Pig has become one of maximum meat product source, the whole world, simultaneously also for the mankind provide important medicinal industry resource, and such as other heparin of pharmaceutical grade and the cardiac valves etc. for heteroplastic transplantation.In addition, also can there is the common complex inheritance disease of some mankind with it in family pig, thus become the excellent model of research human diseases fundamental biological knowledge.The vent window of existing pig house is all Manual structure, and open and need an artificial fan fan to go to open, labour intensity is large, and speed is slow again, and easily grows mosquito summer.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the automatic mosquito-proof vent that a kind of structure of pig farm is simple, easy to operate, practical.
For achieving the above object, technical scheme provided by the utility model is: a kind of automatic mosquito-proof vent of piggery, it includes several ventilation windows be provided with on pig house exterior wall, each vent oral pore hole place all orders is equipped with Anti-mosquito mesh, ventilation window side walls is provided with vertical track, orbit altitude is the twice of vent open height, article two, between track, activity is equipped with casement, casement top is provided with stay cord, wall above ventilation window is provided with ventilation pulley, ventilation pulley is provided with the pull rope be connected with pull rope mechanism, stay cord one end is connected with pull rope after upwards walking around ventilation pulley, rail base is provided with spacing support block or positive stop strip.
Described track top is provided with deflecting roller, and stay cord is walked around deflecting roller successively and is connected with pull rope with after ventilation pulley.
The utility model, after employing such scheme, drives the fan window of a whole fan wall to carry out synchronization lifting and locking by a winch and several ventilation pulleys; The structure of this programme is simple, easy to operate, without the need to manual operation, practical.
Accompanying drawing is described
Fig. 1 is overall structure schematic diagram of the present utility model.
