As the electric telescopic rod 41 is started, the output end of the electric telescopic rod 41 will perform a telescopic movement, thereby pushing or pulling the water pipe 14 to move synchronously. Through the above structure, on the one hand, the water pipe 14 can be limited and fixed, which reduces the loosening of the water pipe 14 caused by the long-term operation of the water pump. At the same time, by starting the electric telescopic rod 41, the water pipe 14 can be driven to move synchronously, thereby adjusting the position of the water pipe 14.

At this time, by setting the second brush 6, the magnetic ball 22 can simultaneously brush the inner wall of the feed barrel 12 when it hits the inner wall of the feed barrel 12. Through the above structure, the cleaning effect of the magnetic ball 22 on the inner wall of the feed barrel 12 is further enhanced.
[0029] like Figure 3As shown, the second brush 6 is made of a flexible material. Through the above configuration, compared with a hard material, the soft second brush 6 can fit more closely to the inner wall of the feed bucket 12 , thereby achieving cleaning and scrubbing of the inner wall of the feed bucket 12 .

At this time, with the rotation of the auger 17, the cleaning liquid carried in the middle of the auger 17 can be synchronously thrown away, so that the cleaning liquid is diffused. At the same time, the remaining cleaning liquid will drip onto the top of the arc plate 18 and then be smashed open. With the rotation of the auger 17, the arc plate 18 will be synchronously driven to rotate. At this time, with the rotation of the arc plate 18, the rotating rod 2 at the bottom of the arc plate 18 will be driven to rotate synchronously. At this time, with the rotation of the rotating rod 2, the multiple first elastic bands 21 at the bottom of the rotating rod 2 will rotate synchronously. At this time, the rotating first elastic band 21 will drive the magnetic ball 22 to rotate. At this time, the rotating magnetic ball 22 will be attracted by the magnetic block 23, and gradually approach the magnetic block 23.

When the magnetic ball 22 and the magnetic block 23 are attracted, the magnetic ball 22 will continuously contact the inner wall of the feeding barrel 12. As the rotating rod 2 rotates, the fixed ring 3 in the middle of the rotating rod 2 will also rotate. At this time, as the fixed ring 3 rotates, the sliding ring 32 can be driven to rotate synchronously. At this time, as the sliding ring 32 rotates, the pull rope 33 and the counterweight block 34 in the middle of the sliding ring 32 will rotate synchronously. At this time, as the pull rope 33 and the counterweight block 34 rotate, and as the counterweight block 34 generates gravity, the second elastic band 31 will be continuously pulled, thereby driving the sliding ring 32 to continuously slide in the middle of the rotating rod 2. At this time, the sliding sliding ring 32 will drive the first brush 35 to continuously move the middle of the rotating rod 2 During scrubbing, as the water pump inside the water tank 13 is started, the water pump will shake to a certain extent. At this time, as time goes by, the vibration generated by the water pump will cause the water pipe 14 to loosen. At this time, a fiber ring 42 is installed in the middle of the water pipe 14, and then the fiber ring 42 is connected by the connecting rod 4 and the electric telescopic rod 41, so as to fix and limit the water pipe 14. At the same time, when the position of the water pipe 14 needs to be adjusted, the electric telescopic rod 41 is started. As the electric telescopic rod 41 is started, the output end of the electric telescopic rod 41 will perform telescopic movement, thereby pushing or pulling the water pipe 14 to move synchronously, and the magnetic ball 22 will be adsorbed by the magnetic block 23. At this time, as the magnetic ball 22 is adsorbed by the magnetic block 23, the magnetic block 23 will also be synchronously adsorbed by the magnetic ball 22.At this time, as time goes by, the position of the magnetic block 23 will shift. At this time, the baffle 5 and the baffle rod 51 cooperate to limit and fix the magnetic block 23. As the rotating rod 2 rotates, the magnetic ball 22 will rotate synchronously. At the same time, as the magnetic block 23 is adsorbed, the magnetic ball 22 will continuously contact the inner wall of the feed barrel 12. At this time, by setting the second brush 6, the magnetic ball 22 can knock on the inner wall of the feed barrel 12 and brush the inner wall of the feed barrel 12 synchronously.
