The left end of one of the rotating rods 125 is connected to the drive shaft of the third motor 129, and the third motor 129 is installed on the outside of the box body 2.

[0050] Furthermore, the pulley assembly 128 includes a pulley installed at the end of the rotating shaft 125, and the pulleys are connected and transmitted through a belt.

[0051] After the fruits and vegetables are cleaned, the drainage cleaning hole assembly 12 can be controlled to operate. The third motor 129 is controlled to start and drive the rotating rod 125 to rotate. The multiple rotating rods 125 are transmitted through the pulley assembly 128, so that the multiple rotating rods 125 can rotate at the same time, and the worm 126 and the worm wheel 127 are driven to engage and transmit during rotation. When the worm wheel 127 rotates, the corresponding vertical screw rod 124 can be driven to rotate. The vertical screw rod 124 is threadedly installed with the end of the horizontal strip plate of the frame 121, so the entire frame 121 can be controlled to slide vertically relative to the vertical guide rail 123 and the inner wall of the box body 2. When moving downward, the sealing plug 122 can leave the drainage hole 15. At this time, the cleaning liquid in the cleaning cavity of the box body 2 can be discharged from the drainage hole 15 into the sewage cavity, and then discharged from the main sewage pipe 13. When discharging sewage (contaminated cleaning liquid), clean water can be flushed into the sewage discharge chamber from the flushing pipe in conjunction with an external flushing pump. At the same time, clean water can also be flushed into the box body 2 through the pipe 8 and the nozzle 9 with the cooperation of the water pump, thereby speeding up the cleaning efficiency inside the box body 2, maintaining the cleanliness of the inside of the box body 2, and facilitating subsequent reuse.
