Description

Technical Field

[0001] The invention relates to the field of livestock and poultry breeding equipment, and in particular to an automatic feeding system for a rotary circular livestock house. Background Art

[0002] The traditional manual feeding method has problems such as cumbersome operation, low efficiency, and incomplete equipment cleaning. For example, when the breeder needs to manually carry feed, whether it is bagged feed or bulk feed, it requires a lot of physical labor. And the speed of manual feed addition is relatively slow, especially in large livestock houses, it takes a long time to complete a feed addition, which affects the overall efficiency of the feeding work. At the same time, after the livestock finish eating, if the troughs and feeding equipment are not cleaned in time or thoroughly, it is easy to breed bacteria, posing a threat to the health of the livestock.

[0003] With the continuous development of science and technology, modern animal husbandry has adopted automated feeding systems to improve the quality, management efficiency and economic benefits of feeding. For example, CN 221807708 U invention discloses "a pig house feed supply mechanism", in which the gear in the equipment drives the feed bucket to rotate through the mounting shaft, so that the feed in the feed bucket is introduced into the pig feeding bucket through the inverting hopper for feeding; CN 220422733 U invention discloses "a box-type pig house quantitative feed feeding device", firstly, the feed and water are mixed to form nutrients, and after the mixing is completed, the controller controls the switch of the solenoid valve to feed the pigs at a fixed time.

[0014] The specific implementation method is: when the pigs only need to eat, a signal is transmitted to the controller 25 through the computer 27, and the controller 25 outputs a signal to control the feed self-priming pump 2 and the water pump 16. The feed self-priming pump 2 sends the feed in the feed grinder 1 into the feed mixing box 3, and the water pump 16 sends the tap water tank 15 into the feed mixing box 3 through the water supply pipe 17, and the feed mixing work is performed in the feed mixing box 3. At this time, the controller 25 counts until the feed mixing is finished, the feed self-priming pump 2 and the water pump 16 are turned off, the motor 10 is started, the feed pump 4 and the second-layer feed pipe control valve 61 are opened, the motor drives the pinion 11 to operate, and the pinion 11 drives the slewing bearing rotating disk 13 on the slewing bearing fixed disk 14 to rotate. As the slewing bearing rotating disk 13 rotates, the rotating bearing I 81, the rotating bearing II 82, and the rotating bearing III 83 also rotate, the second-layer feed pipe 6 rotates with the rotating bearing II 82, and the third-layer feed pipe 7 rotates with the rotating bearing III 83. At this time, the feed pump 4 delivers the feed to the second-layer feed pipe 6 through the feeding mother pipe 5, the second-layer feed pipe control valve 61 is opened, and the second-layer feed pipe 6 rotates and sequentially delivers the feed to each food trough 23 of the second layer. If the feed of the second layer is added, after the second-layer feed pipe control valve 61 is closed, the third-layer feed pipe control valve 71 is opened, and the feed is delivered to each food trough 23 of the third layer through the third-layer feed pipe 7 rotation in sequence until the feed of the third layer is also added.

[0015] When all the pigs have finished eating, all the level meters 26 detect that the feed height has not changed. The level meters 26 transmit signals to the controller 25. The controller 25 controls the water pump 16, the second-layer feeding pipe control valve 61, and the second-layer drainage control valve 19 to open. The tap water tank 15 supplies water to the feed mixing box 3 to clean the feed mixing box 3. Then the tap water is sequentially supplied to the main feeding pipe 5, the second-layer feeding pipe 6 to the second-layer trough 23. The main feeding pipe 5, the second-layer feeding pipe 6, and each trough 23 on the second layer are flushed while the pigs are also fed with water. The flushed water and the residual food enter the residual food recovery box 22 through the second-layer drainage pipe 18 for recycling. After the second-layer trough 18 is cleaned, the second-layer drainage control valve 19 and the second-layer feeding pipe control valve 61 are closed, and the third-layer drainage control valve 21 and the third-layer feeding pipe control valve 71 are opened to flush each trough 23 and related pipes on the third layer and feed water to the pigs on the third layer. The working principle is the same as that of the second layer. Finally, the tap water and leftover food enter the leftover food recovery box 22 for recycling. When the cleaning and watering work of the three layers is completed, the three-layer drainage control valve 21 and the three-layer feed pipe control valve 71 are closed, thus completing the automatic feeding and feeding system cleaning work of the entire pig house. The heater 28 and sterilization equipment 29 in the leftover food recovery box 22 heat and sterilize the leftover food respectively, so that the leftover food can be recycled to avoid feed waste.
