The working principle is as follows: the floor of the pigsty 5 is the elevated net bed 23, pigs live on the net bed, the environment is comfortable, the pig excrement can directly fall into the excrement collecting chamber from the leak, the pig excrement can be cleaned without water in the whole process, the cleaning is convenient, and the labor force is saved. Open aluminium window 21 ventilation summer in the pig house, close aluminium window 21 cold-proof winter, start negative pressure fan 4, the air flows downwards through the leaks of overhead net bed 23 via the upper strata, and pig house foul smell, dust are in time taken away from the underground, reach ventilation deodorization effect, simultaneously, air-dry excrement and urine, concentrated urine reaches the excrement and piles the solidification, and the clear excrement of manual work of being convenient for is flowed to no sewage. Go into as required in the pressurization bin 14 disinfectant, deodorant or water, work as solenoid valve 16 and switch on with the power, disinfectant, deodorant or water in the pressurization bin 14 just can be followed spout 8 blowout to it is right the pig house is disinfected, is washd and multiple operations such as deodorization, saves labour, simultaneously the water economy resource. When the pigs are driven into the cage 17, the ascending or descending switch on the lifting mechanism is started, the rope is automatically wound on the driving motor 20 or released, so that the cage 17 is driven to ascend and descend between the first floor excrement collecting chamber 2 and the second floor raising chamber 1 through the lifting channel, the pigs are carried upstairs and downstairs, and labor force is saved. The feed delivery pump 25 is started, feed is delivered to the automatic pig feeding device 12 through the feed main pipe 10 and the discharge pipeline 11, automatic feeding is achieved through mechanical feeding, unmanned feeding is achieved, the working strength of feeding personnel is reduced, and labor cost is saved.

The working principle of the automatic pig feeding and feeding device 12 is as follows: through manual rotation the screw rod 126, make the screw rod 126 along vertical direction motion to drive go out the feed cylinder 122 and reciprocate, thereby adjust go out the feed cylinder 122 with the size of the clearance 1222 between the charging tray 125, thereby control the discharge capacity, prevent that the fodder from flowing out too much and being polluted and extravagant. Because the feed has certain gravity and is accumulated in the gap, the feed is firm and difficult to flow out, when the pig pushes the iron rings 1219 on the discharging barrel 122, the discharging barrel 122 is rotated, the feed is loosened and flows out, and the purpose of automatically taking the feed by the pig is realized. The discharging barrel 122 is connected to the connecting rod 128, so that the connecting rod 128 is rotated by the rotation of the discharging barrel 122, so that the stirring member 1210 on the connecting rod 128 is rotated, thereby scraping the fodder adhered to the inner wall of the discharging pipe 124, preventing the discharging pipe 124 from being blocked, and facilitating the smooth outflow of the fodder. The water economizer 1212 can control the free outflow of water, so as to save water, that is, when the main switch 1214 on the water inlet pipe 1211 and the water-saving switch 1215 on the water economizer 1212 are opened, water flows from the water outlet 1221 into the water tank 1218 until the water outlet 1221 contacts with the water in the water tank 1218, and the outflow of water is stopped; when the pig drinks the water in the water tank 1218, the water outlet 1221 can not contact the water, and the water flows out again to fill the water tank 1218, so as to realize the purpose of automatic water supply, prevent the water from being polluted and save water resources. The inner wall of the storage barrel 121 is provided with a pressure sensor 1217, the pressure sensor 1217 is electrically connected with the controller 24, and when the pressure sensor 1217 detects that the weight of the feed in the storage barrel 121 reaches a set value, a signal is transmitted to the controller 24, so that the power supply of the feed delivery pump 25 is cut off, and the feed is prevented from overflowing to cause waste.

The above description is intended to describe in detail the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the claims of the present invention, and all equivalent changes and modifications made within the technical spirit of the present invention should fall within the scope of the claims of the present invention.
