Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] See also Figure 1-3 In this embodiment, an automatic circulation cleaning device for a train feces collection pipeline includes a flushing box 2, a discharge port 7, a filtering mechanism and a stirring assembly 16. The discharge port 7 is fixedly installed at the center position inside the flushing box 2, the filtering mechanism is arranged at the inner upper part of the flushing box 2, and the stirring assembly 16 is arranged at the inner lower part of the flushing box 2. A circulation pipe 5 is fixedly passed through the left side of the top of the flushing box 2, and a feed pipe 10 and a water inlet pipe 11 are fixedly passed through the left side of the flushing box 2, and a first solenoid valve is installed on the water inlet pipe 11.

[0032] The external thread of the feed pipe 10 is connected with a pipe cover, and the feed pipe 10 is used to add disinfectant or cleaning agent into the flushing box 2, and clean water can be added into the flushing box 2 after the water inlet pipe 11 is connected to the water pipe.

[0033] The filtering mechanism includes a filter screen 6, a push plate 12, a fixed plate 17, a servo motor 20, a guide roller 18, and a support block 19. The filter screen 6 is fixedly installed on the inner wall of the flushing box 2, the push plate 12 extends through one side of the flushing box 2 to the outside, the fixed plate 17 is fixedly installed on the side wall of the flushing box 2, the servo motor 20 is installed on the back of the fixed plate 17, the guide roller 18 is fixed on the output shaft of the servo motor 20 and pressed on the surface of the push plate 12, the support block 19 is fixed on one side of the fixed plate 17 and is located at the bottom of the push plate 12, the support plate 1 is fixedly installed at the bottom of the flushing box 2, the water pump 13 is fixedly installed on the top of the support plate 1, the stirring assembly 16 includes a driving motor, a rotating shaft and a stirring rod, the driving motor is fixedly installed at the bottom of the support plate 1, the rotating shaft is fixed on the output shaft of the driving motor, the rotating shaft extends through the bottom of the flushing box 2 to the inside, and the stirring rod is fixed on the side wall of the rotating shaft.

[0034] The push plate 12 has an L-shaped structure, and one bent end of the push plate 12 is attached to the surface of the filter screen 6 , so that the moving push plate 12 can push the impurities from the surface of the filter screen 6 to the discharge port 7 .

[0035] The stirring component 16 can speed up the mixing of clean water and cleaning agent or disinfectant and mixed water, and adding disinfectant to the mixed water flowing back can achieve the effect of disinfection and sterilization.

[0036] It can be understood that a resistance increasing sleeve is fixed to the outer wall of the guide roller 18, and the resistance increasing sleeve is made of rubber. The friction between the guide roller 18 and the surface of the push plate 12 is increased by the resistance increasing sleeve, so that the rotating guide roller 18 can drive the push plate 12 to move.
