The implementation principle of a feed conveying system in the embodiment of the application is as follows:

when the aseptic chickens in the henhouse 100 need to be raised, the feeding module, the water supply module, the air circulation module and the luminosity adjusting module are powered on at the same time, and then the first main control module, the second main control module, the third main control module and the fourth main control module are powered on; the first main control module controls the lighting lamp 610 to be turned on, and simultaneously the first timing module and the fourth timing module start timing, at the moment, the first quality sensor 340 measures the quality of the feed in the trough 330 in real time and sends a signal to the second main control module, when the second main control module monitors that the first quality sensor 340 reaches a set minimum value, the sterilized feed in the trough 330 is just consumed, at the moment, the first judgment module judges the lighting time of the lighting lamp 610 through the fourth timing module, if the lighting time of the lighting lamp 610 is smaller than or equal to the set time of the first judgment module, at the moment, the judgment is in the morning, the output end of the first judgment module is connected with the input end of the second timing module, at the moment, the second timing module starts timing, and at the same time, the second timing module controls the screw conveyor 320 to run by power, so that the feed in the feed box 310 is automatically conveyed into the trough 330; when the second main control module monitors that the first quality sensor 340 reaches the maximum set value, the feed in the trough 330 reaches the maximum volume value at this time, and the second main control module controls the screw conveyor 320 to stop running; when the second main control module detects that the first quality sensor 340 reaches the minimum value and the second timing module reaches the set time, the second timing module resets, the second timing module enables the spiral conveyor 320 to run electrically again, and the feed in the feed box 310 is automatically conveyed into the trough 330 again; the feed in the trough 330 is automatically fed according to the set time interval of the second timing module by circulating the steps.

If the on-time of the illuminating lamp 610 is longer than the set time of the first judging module, the afternoon is judged, the output end of the first judging module is connected with the input end of the third timing module, the third timing module starts timing, and meanwhile the third timing module controls the spiral conveyor 320 to be powered on to operate, so that the feed in the feed box 310 is automatically conveyed into the feed groove 330; when the second main control module detects that the first quality sensor 340 reaches the maximum set value, the feed in the trough 330 reaches the maximum capacity value at this time, and the second main control module controls the spiral conveyor 320 to stop running; when the second main control module detects that the first quality sensor 340 reaches the minimum set value and the third timing module reaches the set time, the third timing module resets and controls the screw conveyor 320 to run by electrifying again, so that the feed in the feed box 310 is automatically conveyed to the trough 330. The feed in the trough 330 is automatically fed according to the set time interval of the third timing module by the circulation. When the first timing module reaches the first set value, the first main control module controls the illuminating lamp 610 to be turned off, the first timing module continues timing at the moment, and when the first timing module reaches the second set value, the illuminating lamp 610 is turned on again at the moment, and meanwhile, the first timing module is reset to perform the next cycle. The material box 310 is automatically fed to the material groove 330 by reciprocating.

By arranging the first timing module, the lighting lamp 610 can be automatically and accurately controlled to be turned on and off; the setting of second timing module and third timing module realizes the feed law when according to the activity of sterilization chicken, selects different feeding frequency, and the setting of fourth timing module and first judgement module realizes automatically that the feed frequency in silo 330 adjusts according to the feed law when aseptic animal moves about, and the food intake when can guaranteeing aseptic chicken activity like this also can reduce the dwell time of fodder in silo 330 to reduce the probability of fodder infecting in silo 330. By the operation, the feed in the feed box 310 can be automatically conveyed to the feed groove 330, so that the feed in the feed groove 330 can be automatically fed, the probability that the sterile feed and the sterile animals are infected by people is reduced, the probability that the people are infected by the sterile animals is reduced, and the safety of the people and the sterile animals in the sterile breeding process is ensured.

When the first timing module runs to the first set value, at the same time when the illuminating lamp 610 is turned on, the second quality sensor 350 starts to read the initial quality a of the feed in the feed box 310, and records the data a in the second main control module; the second quality sensor 350 then reads the real-time quality b of the feed in the bin 310 and records the data b in the second main control module, wherein the data a is a fixed value and the data b is a real-time transformed value during one cycle of turning on and off the illumination lamp 610; assuming that the feed consumption of the aseptic chicken required to be fed every day is a fixed value c, inputting the fixed value c into the second main control module, reading data a and data b recorded in the second main control module in real time by the second judging module, judging the size between a-b and the fixed value c, when the value a-b is smaller than the fixed value c, continuously feeding the feed tank 310 to the feed tank 330 until the value a-b is equal to the fixed value c, operating the third judging module, reading the data of the first mass sensor 340 by the third judging module through the second main control module, judging whether the feed is still in the feed tank 330, when the first mass sensor 340 reaches the minimum set value, indicating that no feed is in the feed tank 330, controlling the illuminating lamp 610 to be turned off by the third judging module, controlling the feed sucking machine 362 to be electrically operated, and recovering the residual feed into the collecting box 363 if the feed in the feed tank 330 is residual; or when the first timing module runs to the second set value, the illuminating lamp 610 is automatically turned off, and the suction machine 362 is controlled to be powered on to run, at this time, if the feed in the trough 330 is remained, the remained feed is recovered to the collection box 363.

Since the weight change of the aseptic chickens is particularly taken care of during the breeding of the aseptic chickens in order to enable the aseptic chickens to grow better and maintain good egg production, the daily feed amount in the henhouse needs to be strictly controlled within a set value. However, in the process of eating the aseptic chicken, a certain error occurs in the daily food intake within the specified lighting time; when the light is turned on, the feeding speed of the aseptic chicken is too fast, the feed consumption reaches the feed supply amount in the current day in advance, and at the moment, in order to reduce the activity of the aseptic chicken after feeding, the aseptic chicken keeps good weight growth, the illuminating lamp 610 needs to be turned off, so that the aseptic chicken can take a rest in the morning. If in the period of turning on the light, aseptic chicken feed speed has been too slow, when first timing module arrived the time of turning off the light, when the feed consumption of current day had not reached the supply volume of current day's fodder, in order to guarantee the normal food of aseptic chicken the next day this moment, also need close light 610 this moment, take away the remaining fodder in silo 330 through fodder recovery unit 360 simultaneously, reduce aseptic chicken and eat the volume at night, so that make aseptic chicken quiet rest at night, and the second day can be better eat daytime, and then make aseptic chicken raise better.

By arranging the second judging module and the third judging module, the feeding speed of the aseptic chicken is too high, the feed consumption reaches the feed supply amount on the same day in advance, the lighting lamp 610 is turned off in time, the activity of the aseptic chicken after feeding is reduced, the aseptic chicken keeps good weight increase, and the feeding is better; by arranging the feed recovery device 360, when the feeding speed of the aseptic chickens is too slow in the period of turning on the light, the timing time of the first timing module is reached, and the illuminating lamp 610 is turned off, at the moment, the feed recovery device 360 can pump away the residual feed in the trough 330 in time, so that the feeding amount of the aseptic chickens at night is reduced, the aseptic chickens can rest quietly at night, and the aseptic chickens can feed better in the daytime in the next day, so that the aseptic chickens are better fed; meanwhile, the recycled feed can enter the collecting box 363 and can be used by the sterile chickens again after sterilization, so that the time for storing the residual feed in the trough 330 at night is reduced, the degree of feed pollution is reduced, and the waste of the feed is reduced.

When the illuminating lamp 610 is turned on, the aseptic chicken needs to drink water, the third main control module receives an illuminating lamp 610 turning-on signal fed back by the first main control module, and then the third main control module controls the water inlet valve 420 to be turned on, so that water in the water supply pipeline 410 is conveyed into the drinking water pipeline 430 to be drunk by the aseptic chicken; when the lighting lamp 610 is turned off, the aseptic chicken does not need to drink water, at the moment, the third main control module receives a lighting lamp 610 turning-off signal fed back by the first main control module, the third main control module controls the water inlet valve 420 to be turned off, so that water in the water supply pipeline 410 stops being conveyed into the drinking water pipeline 430, and meanwhile, the third main control module controls the fifth timing module to start recording the turning-on and turning-off times of the lighting lamp 610 once, which represents that the drinking water pipeline 430 is used for one day; so set up for aseptic chicken at night when having a rest, water supply pipe 410 no longer supplies water to drinking water pipe 430, has reduced the water storage volume at night among the drinking water pipe 430, makes drinking water pipe 430 can flow into more fresh water the next day, and then makes aseptic chicken can drink more fresh water the next day, improves aseptic chicken's drinking water safety.

When the number of times recorded by the fifth timing module reaches a set value, namely the drinking water pipeline 430 reaches a set number of days of use, the fifth timing module feeds back a signal to the third main control module, the third main control module controls the water outlet valve 440 to be opened, so that water in the water supply pipeline 410 directly flows out of the drinking water pipeline 430, the fifth timing module resets at this time, next round of timing is started, and meanwhile, the sixth timing module starts timing; when the sixth timing module reaches the set time, the sixth timing module feeds back a signal to the third main control module, and the third main control module controls the water outlet valve 440 to close, thereby completing the automatic cleaning of the drinking water pipeline 430.

When the henhouse 100 automatically supplies and supplies water, the fourth main control module controls the first fan 511, the bypass fan 520, the second fan 531 and the air conditioning system 540 to be powered on and operated at the same time, the temperature sensor 550 monitors the temperature in the henhouse 100 in real time and feeds the temperature back to the air conditioning system 540, when the temperature in the henhouse 100 cannot meet a set value, the air conditioning system 540 operates, and when the temperature in the henhouse 100 reaches the set value again, the air conditioning system 540 stops operating; so set up, can be so that the fresh air that gets into in the chicken coop 100 be the constant temperature air, can adjust the temperature in the chicken coop 100, and then make the constancy of temperature in the chicken coop 100, more do benefit to the growth of aseptic chicken. Meanwhile, constant-temperature air blown out of an air outlet of the air conditioning system 540 enters the first fan 511 through the first air inlet pipeline 512, enters the first air outlet pipeline 513 from an air outlet end of the first fan 511, and is conveyed into the henhouse 100 from an air inlet end of the henhouse 100; then the circulating fan 520 accelerates the circulation of the conveyed constant-temperature air in the henhouse 100, so that the new and old air in the henhouse 100 can be replaced fully; the turbid air in the henhouse 100 is then introduced into the second fan 531 through the second air inlet duct 532, and then discharged out of the henhouse 100 through the second air outlet duct 533. Through from 100 top air intakes of chicken coop, exhaust from 100 lateral wall lower extremes of chicken coop, the impurity of this kind of setting suspension in can 100 air of chicken coop is blown the lower extreme through blowing from the top, then together with subaerial fine hair etc. float and sink from 100 air outlets of chicken coop discharge, make the air in the chicken coop 100 can also play clear effect to 100 environment of chicken coop at the circulating in-process, the improvement chicken coop 100's that can be better air quality, improve the sanitary environment of chicken coop 100, and then reduce the morbidity and the mortality of chicken coop.

The turbid air discharged from the second air outlet pipe 533 enters the air inlet pipe 563 through the draft tube 561 and further enters the filtering tank 562, impurities such as fluff in the turbid air can be filtered in water through the filtering of the filtering tank 562, and meanwhile, the filtered clean air can be discharged to the atmosphere from the air outlet pipe 567; by the operation, the henhouse 100 does not pollute the atmospheric environment in the air circulation process, the environmental protection requirement is met, the possibility that external germs in the henhouse 100 enter the henhouse 100 through the air outlet mechanism 530 is reduced, and the air quality in the henhouse 100 is improved; when the impurities in the water in the filtering tank 562 are more, the turbidity sensor 566 will feed back a signal to the fourth main control module, and the fourth main control module controls the outlet valve 565 of the filtering tank to open, so that the sewage in the filtering tank 562 is discharged from the drain pipe 569, and then the fourth main control module controls the inlet valve 564 of the filtering tank to open, so that the clean water is delivered into the filtering tank 562 from the inlet pipe 568, and the filtering tank 562 is changed. Through changing water for the filter tank 562, the cleaning of the filter tank 562 by workers is facilitated, the cleaning efficiency of the filter tank 562 is improved, and the possibility that bacteria and viruses are bred in the reservoir is reduced.
