[0027] The working principle of the above embodiment is:

[0028] (1) When using the sewage pipe 5 to discharge the sewage inside the sewage tank 4, start the motor 601, the motor 601 drives the transmission rod 602 to rotate counterclockwise, and the transmission rod 602 drives the transmission cylinder 603 to rotate counterclockwise. Further, the transmission cylinder 603 drives the stirring shaft 605 to rotate through the main bevel gear 606 and the secondary bevel gear 607, and then drives the multiple stirring rods 608 to stir the sewage, thereby preventing sediment from settling and facilitating the discharge of sediment from the sewage pipe 5 for cleaning;

[0029] (2) When it is necessary to dismantle the sewage tank 4 to clean its interior, start the motor 601 in reverse, so that it drives the transmission rod 602 to rotate clockwise, further drives the missing gear 710 to rotate clockwise, and the missing gear 710 drives the tooth plate 709 to move to the left, and the tooth plate 709 drives the movable plate 704 to move to the left along the guide rod 703, further making the movable plate 704 drive the limit block 705 to disengage from the limit hole 706, and then the sewage tank 4 can be slid forward to drive the plug block 701 to disengage from the socket 702 and the transmission cylinder 603 to disengage from the transmission rod 602 to complete the dismantling of the sewage tank 4. Unloading, when the movable plate 704 moves to the left, it will cooperate with the limit plate 708 to stretch the spring 707. When installing the sewage tank 4, the plug-in block 701 is inserted into the socket 702, and the motor 601 is controlled to rotate counterclockwise. At this time, the spring 707 cooperates to move the tooth plate 709 to the right, and the limit block 705 is inserted into the limit hole 706 for limiting. When the spring 707 is restored, the tooth plate 709 is close to the left and engages with the missing gear 710. At this time, continuing the counterclockwise rotation of the motor 601 will not always push the tooth plate 709 to move right, thereby facilitating the cleaning mechanism to stir.
