[0020] The door panel at the front end of the box body 1 is opened, and the live pig is hung inside the box body 1 through the hook 6, and then the driving motor 2 is started. The driving motor 2 drives the rotating block 4 to rotate, and the rotating block 4 then drives the live pig hanging below to rotate forward. While the rotating block 4 rotates, it drives the driving gear 5 fixed on its surface to rotate. The rotation of the driving gear 5 drives the driven gear 8 meshing with the surface of the driven gear 8 to reverse, and the driven gear 8 is meshed with the inner ring of the annular rack 7 at the same time. The driven gear 8 then drives the connecting rod 11 to slide along the annular grooves at the upper and lower ends of the box body 1.

[0021] A square hair outlet pipe 12 is fixedly connected to the lower end of the box body 1, and the square hair outlet pipe 12 extends to the interior of the box body 1. A water tank 13 is arranged below the square hair outlet pipe 12. A through hole is opened on the surface of the square hair outlet pipe 12. A filter screen 14 is fixedly connected to the inside of the square hair outlet pipe 12. The filter screen 14 is inclined and extends to the outside of the square hair outlet pipe 12 through the through hole. A collecting box 15 is arranged below the extended part of the filter screen 14. The scraped pig hair slides into the interior of the collecting box 15 through the filter screen 14. A water pump 16 is fixedly connected to the rear of the box body 1. The water outlet end and the water inlet end of the water pump 16 are respectively fixedly connected with a water outlet pipe 17 and a water inlet pipe 18. The water inlet pipe 18 extends to the interior of the water tank 13 and is fixedly connected. The water outlet pipe 17 extends to the interior of the box body 1 and is fixedly connected with a nozzle 19.

[0022] Start the water pump 16, and the water pump 16 pumps out the clean water in the water tank 13 through the water inlet pipe 18, and then sprays it out through the water outlet pipe 17 and the nozzle 19 to clean the pig hair scraped off the surface of the pig. The pig hair flows out through the square hair outlet pipe 12 along the water flow, and is filtered by the filter screen 14. The filtered pig hair slides down the filter screen 14 to the inside of the collection box 15, and the filtered clean water passes through the filter screen 14 and falls into the water tank 13, thereby achieving water circulation. By arranging the water pump 16 and the water tank 13, water circulation can be achieved, and the water used to rinse the pigs can be rinsed multiple times, thereby reducing the consumption of fresh water resources, which is beneficial to saving water resources, reducing the use of fresh water, reducing the cost expenditure of water resources, and helping to reduce production costs. At the same time, it reduces the discharge of wastewater from farms or slaughterhouses, reduces pollution to the environment, and meets environmental protection requirements.

[0023] Usage: First, open the door panel at the front end of the box 1, hang the live pig inside the box 1 through the hook 6, and then start the driving motor 2. The driving motor 2 drives the rotating block 4 to rotate, and the rotating block 4 then drives the live pig hanging below to rotate forward. The rotating block 4 drives the driving gear 5 fixed on its surface to rotate while rotating. The rotation of the driving gear 5 drives the driven gear 8 meshing on its surface to reverse, and the driven gear 8 is meshed with the inner ring of the annular rack 7 at the same time. The driven gear 8 then drives the connecting rod 11 to slide along the annular grooves at the upper and lower ends of the inside of the box 1. The rotation and sliding of the connecting rod 11 drives the dehairing roller 10 to move together with the connecting rod 11. The forward rotation of the live pig and the reverse rotation of the dehairing roller 10 can make the dehairing efficiency faster.

[0024] Then the water pump 16 is started, and the water pump 16 pumps out the clean water in the water tank 13 through the water inlet pipe 18, and then sprays it out through the water outlet pipe 17 and the nozzle 19 to clean the pig hair scraped off the surface of the live pig. The pig hair flows out through the square hair outlet pipe 12 along the water flow, and is filtered by the filter screen 14. The filtered pig hair slides down the filter screen 14 to the inside of the collection box 15, and the filtered clean water passes through the filter screen 14 and falls into the water tank 13, thus achieving water circulation.
