[0056] Working principle: When the sewage suction truck uses the sewage discharge device to discharge sewage, first open the water valve set on the surface of the sewage discharge pipe 413, and then the sewage flows out of the sewage discharge pipe 413 through the square funnel 411. In this process, most of the small debris is left on the surface of the filter screen 412, and a small part of the debris is left on the inner bottom surface of the vehicle body 1. At this time, the motor 32 is started, and the output shaft of the motor 32 rotates to drive the rotating shaft 33 to rotate, and the rotating shaft 33 rotates to drive the output gear 34 to rotate. The output gear 34 is meshed with the gear plate 35, so that the output gear 34 rotates and drives the block 31 to move forward. In this process, the slider 37 and the gear plate 33 are connected. 5 slides, the block 31 moves through the connecting plate 36 to push the frame 41 to move, and the scraper 45 arranged in the frame 41 is used to clean up the debris. When the scraper 45 moves to the square funnel 411, the elastic potential energy generated by the spring 48 makes the tooth plate 2 46 move upward to drive the transmission gear 43 to rotate. The transmission gear 43 rotates to make the tooth plate 1 44 move downward, so as to achieve the effect of always fitting with the bottom surface of the vehicle body 1. In this process, the limit rod 47 slides with the tooth plate 2 46. When the output gear 34 moves to the other end of the tooth plate 3 35, the debris is discharged by opening the gate installed on the surface of the vehicle body 1.
