The disinfection component 6 and the disinfection chamber 1 are equipped with nozzles on the inner walls of both sides for rinsing the sides of the robot. The nozzles are connected to the water tank 7 via a pump to facilitate spraying disinfection onto the side walls of the robot. A water tank 7 is provided on the back side of the disinfection chamber 1 to provide rinsing water for the disinfection component 6. A filter box for filtering rinsing wastewater is provided inside the disinfection chamber 1 and outside the disinfection component 6. An ultraviolet lamp 8 is fixedly installed in the center of the top wall of the disinfection chamber 1. An ozone generator 9 is fixedly installed on the top of the disinfection chamber 1. The outlet of the ozone generator 9 is connected to the disinfection chamber 1 through a pipe.

[0019] See Figure 1-2 The top two sides of the disinfection chamber 1 are equipped with exhaust components, including exhaust fans 24 fixedly installed on the top two sides of the disinfection chamber 1. The other side of the exhaust fan 24 is connected to an exhaust pipe 25, and the exhaust pipe 25 leads into the purification equipment. The ozone inside the disinfection chamber 1 can be extracted through the exhaust fan 24 and introduced into the purification equipment along the exhaust pipe 25.

[0020] See Figure 3-4The cleaning and disinfection component 6 includes a rotating seat 10 rotatably connected to the center of the filter box. Six sets of guide channels 20 are arranged on the outer side of the rotating seat 10, and the guide channels 20 are set at an inclination of 15°. The guide channels 20 facilitate the flow of flushing wastewater into the filter box. Brushes 11 are installed on the top side of the rotating seat 10, and six sets of high-pressure rotating nozzles 12 are arranged on the outer side of the rotating seat 10. An ultraviolet disinfection lamp 13 is installed between every two adjacent sets of high-pressure rotating nozzles 12. A transmission component is provided on the bottom side of the filter box to drive the rotating seat 10 to rotate back and forth. The transmission component can drive the rotating seat 10 to rotate back and forth, which will brush the robot chassis and scraper through the brushes 11. Then, the high-pressure rotating nozzles 12 spray chlorine-containing disinfectant to rinse the chassis and scraper, improving the cleaning effect. After cleaning, the robot chassis and scraper can be disinfected and sterilized by ultraviolet disinfection lamps 13.

[0021] See Figure 3-4 The transmission component includes a support 14 fixedly installed on the bottom side of the filter box, a guide rod 15 fixedly installed between the supports 14, a rack plate 16 sleeved on the outer side of the guide rod 15, a gear 17 fixedly installed at the center of the bottom side of the rotating seat 10, and the gear 17 and the rack plate 16 meshing with each other. The rack plate 16 has a support edge 18 at its front end, and a reciprocating cylinder 19 centrally symmetrically arranged is fixedly installed on the outer side of the rack plate 16. The telescopic end of the reciprocating cylinder 19 is fixedly installed at the end of the support edge 18. By starting the reciprocating cylinder 19, the rack plate 16 can be driven to slide along the outer side of the guide rod 15, which in turn will drive the rotating seat 10 to rotate back and forth through the gear 17 meshing with the rack plate 16.

[0022] See Figure 3-4 The filter box includes a liquid storage tank 21 fixedly installed inside the disinfection chamber 1. A filter screen 22 is fixedly installed inside the liquid storage tank 21. Drain pipes 23 are fixedly installed on both sides of the bottom of the liquid storage tank 21. The wastewater is filtered through the filter screen 22 to separate solids and liquids, and the separated liquid can be discharged to the outside through the drain pipes 23 to achieve harmless discharge.

[0023] In use, the manure cleaning robot travels to the inclined platform 4, opens the sensor door 2, and then moves along the inclined platform 4 into the disinfection chamber 1, landing on the support plate 5 with its chassis exposed to the cleaning and disinfection components 6. Then, closing the sensor door 2 activates the reciprocating cylinder 19, which drives the rack plate 16 to slide along the outside of the guide rod 15. This, in turn, drives the rotating seat 10 to rotate back and forth via the gear 17 meshing with the rack plate 16. The brushes 11 then scrub the robot's chassis and scraper. A high-pressure rotating nozzle 12 sprays chlorine-containing disinfectant to rinse the chassis and scraper, improving the cleaning effect. After cleaning, the robot's chassis and scraper are irradiated with ultraviolet disinfection lamp 13 for 30 minutes for ultraviolet disinfection and sterilization. Simultaneously, ultraviolet lamp 8 irradiates... The robot's outer surface is disinfected and sterilized, and then ozone generator 9 is used to disinfect the disinfection chamber 1 with ozone for 30 minutes. After disinfection, the ozone inside the disinfection chamber 1 is extracted by starting the exhaust fan 24 and introduced into the purification equipment through the exhaust pipe 25. Then, the sensor door 2 can be opened to move the robot out. At this time, the robot can enter the next pigsty to clean the manure. After the work is completed, it enters the disinfection chamber 1 again for disinfection and sterilization. Finally, it returns to the charging area of ​​the pigsty to charge and standby. At the same time, the flushing wastewater is conveniently guided by the guide channel 20, so that the wastewater flows into the filter box, and then the wastewater is filtered by the filter screen 22 to separate solids and liquids. Then, the separated liquid is discharged to the outside through the drain pipe 23 to achieve harmless discharge.

[0024] In summary, the cleaning and disinfection equipment for the pig farm's cross-pen manure cleaning robot uses brushes 11 to scrub the robot's chassis and scrapers by rotating back and forth. Then, a high-pressure rotating nozzle 12 sprays chlorine-containing disinfectant to rinse the chassis and scrapers. After cleaning, the robot is disinfected and sterilized by ultraviolet lamps 8 and 13, and ozone is generated by an ozone generator 9. After disinfection and sterilization, the robot can enter the next pig pen for manure cleaning, thereby reducing the operating cost of the manure cleaning robot and avoiding cross-infection.
