[0031] Working principle: Before flushing the delivery pipe 7, it is necessary to use a cleaning liquid to clean the inside of the delivery pipe 7. First, start the motor 81. When the motor 81 is started, the threaded rod 83 on the output shaft of the motor 81 rotates clockwise. When the threaded rod 83 rotates clockwise, the threaded sleeve 85 on the threaded rod 83 moves horizontally to the right. When the threaded sleeve 85 moves horizontally to the right, the baffle 86 on the threaded sleeve 85 moves horizontally to the right, so that the cleaning pipe 811 is connected to the inside of the delivery pipe 7. When the cleaning pipe 811 is connected to the inside of the delivery pipe 7, the cleaning liquid in the cleaning box 88 enters the cleaning pipe 811 through the liquid outlet 810. 811 enters the interior of the delivery pipe 7 to clean the interior of the delivery pipe 7. When the cleaning liquid in the cleaning box 88 is insufficient, the float plate 814 touches the trigger button 816 due to the buoyancy. When the trigger button 816 is triggered, the sound 815 sounds an alarm to remind the staff that the cleaning liquid in the cleaning box 88 is insufficient. When the threaded rod 83 rotates counterclockwise, the threaded sleeve 85 on the threaded rod 83 moves horizontally to the left. When the threaded sleeve 85 moves horizontally to the left, the baffle 86 on the threaded sleeve 85 moves horizontally to the left, blocking the cleaning pipe 811 from the delivery pipe 7. At this time, the cleaning liquid in the cleaning box 88 cannot enter the interior of the delivery pipe 7 after entering the cleaning pipe 811.

[0032] After the cleaning liquid cleans the inside of the delivery pipe 7, it is necessary to rinse the inside of the delivery pipe 7. First, slide the water baffle 917 to open the water outlet 911 at the bottom of the water tank 99, and then start the motor 81. When the motor 81 is started, the threaded rod 83 on the output shaft of the motor 81 rotates clockwise. When the threaded rod 83 rotates clockwise, the first collision rod 97 on the threaded rod 83 collides with the force plate 95 on the hydraulic cylinder 92. When the force plate 95 of the hydraulic cylinder 92 is collided, the hydraulic rod 94 moves left and right. When the hydraulic rod 94 moves to the left, the push plate 96 on the hydraulic rod 94 pushes the water inside the water tank 99 through the water outlet 91 1 is squeezed into the water pipe 913. When the hydraulic rod 94 moves to the left, the second collision rod 921 on the hydraulic rod 94 hits the U-shaped iron block 920 inside the water pipe 913, so that the U-shaped rubber block 919 is deformed, and the flow of water inside the water pipe 913 is controlled. The water in the water pipe 913 flows into the flushing pipe 914, and the water in the flushing pipe 914 flushes the inside of the delivery pipe 7 through the nozzle 915. When the threaded rod 83 rotates counterclockwise, the first collision rod 97 on the threaded rod 83 hits the force plate 95 on the hydraulic cylinder 92. When the force plate 95 of the hydraulic cylinder 92 is hit, the hydraulic rod 94 moves left and right. When the hydraulic rod 9 When the hydraulic rod 94 moves to the left, the push plate 96 on the hydraulic rod 94 squeezes the water in the water tank 99 into the water pipe 913 through the water outlet 911. When the hydraulic rod 94 moves to the left, the second collision rod 921 on the hydraulic rod 94 collides with the U-shaped iron block 920 in the water pipe 913, so that the U-shaped rubber block 919 is deformed, and the flow of water in the water pipe 913 is controlled. The water in the water pipe 913 flows into the flushing pipe 914, and the water in the flushing pipe 914 flushes the inside of the delivery pipe 7 through the nozzle 915. In order to prevent the flushing from being unclean, the nozzle 915 needs to be adjusted. First, the motor 81 is started. When the motor 81 is started, , the threaded rod 83 on the output shaft of the motor 81 rotates clockwise. When the threaded rod 83 rotates clockwise, the third collision rod 102 on the threaded rod 83 collides with the collision plate 101. When the collision plate 101 is collided, the collision nozzle 915 slides inward to change the flushing angle of the nozzle 915. When the threaded rod 83 rotates counterclockwise, the third collision rod 102 on the threaded rod 83 collides with the collision plate 101. When the collision plate 101 is collided, the collision nozzle 915 slides inward to change the flushing angle of the nozzle 915. When the angle does not need to be adjusted, the nozzle 915 is reset by pushing the reset plate 105.
