[0047] Further,

[0048] In an optional embodiment, a disinfection assembly 5 is installed on the water tank 417, and the disinfection assembly 5 includes a disinfection box 501 fixed on the surface of the water tank 417, a connecting pipe 2 503 fixed on the surface of the connecting pipe 1 419, and a control valve 1 502 installed inside the connecting pipe 1 419. The other end of the connecting pipe 2 503 is fixedly connected to the disinfection box 501, and a control valve 2 504 is installed inside the connecting pipe 2 503.

[0049] In this embodiment: after the cleaning is completed, the control valve 1 502 is closed and the control valve 2 504 is opened. The disinfectant (not shown in the figure) inside the disinfection box 501 is pumped out by starting the water pump 418 and discharged into the connecting pipe 2 503. The connecting pipe 2 503 is discharged along the connecting pipe 1 419 to the inside of the delivery pipe 420 and discharged through the nozzle of the delivery pipe 420, thereby performing a disinfection operation on the cleaned feeding trough body 3.

[0051] Working principle and use process of the utility model: when the feeding device for animal husbandry is in use, when it is necessary to clean the feeding trough body 3, the threaded rod 414 is first rotated to drive the rack 413 to move. Since the rack 413 and the gear 415 are meshed and connected, the gear 415 is driven to rotate. During the movement of the rack 413, it slides on the surface of the square rod 416. The square rod 416 is provided to support the rack 413, increase the stability of the rack 413, and drive the feeding trough body 3 to rotate synchronously with the rotation of the gear 415 until the feeding trough body 3 rotates to 90°. Through this operation, it is convenient to better discharge the cleaned debris during the cleaning process of the feeding trough body 3. , improve the cleaning efficiency. In this process, by pushing the moving plate 405, the rectangular plate 407 is driven to move, and the cleaning head 409 is driven to move synchronously by the rectangular plate 407, so that the cleaning head 409 can be moved to the inside of the feeding trough body 3 and fit with its surface, which can improve the cleaning effect according to actual use needs, and then the locking bolt 406 is rotated, and the moving plate 405 is squeezed by the locking bolt 406, so that the moving plate 405 can be squeezed and locked, and then the servo motor 401 is started, thereby driving the threaded screw 402 to rotate. Since the threaded screw 402 and the moving block 404 are meshed and connected, the moving block 404 is driven to move, and the moving block 404 slides on the surface of the limit rod 403. The moving block 404 can be limited by the limiting rod 403, so that the moving block 404 is more stable during movement. The moving block 404 is moved to drive the rectangular plate 407, the servo motor 408 and the cleaning head 409 to move synchronously. At the same time, the servo motor 408 is started to drive the cleaning head 409 to rotate, so that the inside of the feeding trough body 3 can be cleaned. Regular cleaning of the feeding trough body 3 can remove residual feed and food to prevent bacteria from growing in the trough, thereby keeping the animal's food environment clean and hygienic. A clean feeding trough body 3 not only makes it easier for animals to eat, but also avoids the situation where animals refuse to eat due to uncleanliness, thereby improving the feeding efficiency. At the same time, the water pump 418 is started to pump water. The water inside the box 417 is extracted and transported to the delivery pipe 420 through the connecting pipe 1 419, and discharged through the nozzle on the delivery pipe 420, so that the water spray and the cleaning head 409 cooperate to more effectively remove stains and improve the cleaning effect. After the cleaning is completed, the control valve 1 502 is then closed, and the control valve 2 504 is opened. By starting the water pump 418, the disinfectant (not shown in the figure) inside the disinfection box 501 is extracted and discharged into the connecting pipe 2 503. The connecting pipe 2 503 is discharged into the delivery pipe 420 along the connecting pipe 1 419, and discharged through the nozzle of the delivery pipe 420, thereby performing a disinfection operation on the cleaned feeding trough body 3. Through regular disinfection, the bacteria and viruses in the feeding trough body 3 can be eliminated.To reduce the risk of animals contracting diseases, after use, the feeding trough body 3 is reset, and the adjusting bolt 410 is rotated at the same time, thereby driving the connecting plate 411 to move, and the plug 412 is driven to move through the connecting plate 411, so that the plug 412 is moved out of the limiting hole provided in the rectangular plate 407, and then the position lock of the rectangular plate 407 is released, and the rectangular plate 407 is rotated to drive the servo motor 2 408 and the cleaning head 409 to rotate to 180°, and then the adjusting bolt 410 is rotated in the opposite direction, thereby driving the plug 412 to be inserted into the limiting hole again to lock the position of the rectangular plate 407. At this time, the cleaning head 409 and the servo motor 2 408 are located below the feeding trough body 3, thereby avoiding obstruction to the feeding trough body 3 and affecting the livestock feeding operation, and further improving the use effect of the device.
