When the ultrasonic detector 21 detects that the sludge has reached a suitable position, the rotating motor 11 is controlled to reverse. When the two first slide plates 13 are reattached to one piece, the two electric telescopic rods 15 respectively drive the two squeezing plates 16 to move to the middle. When the two squeezing plates 16 repeatedly squeeze the sludge between them, the water inlet of the water pump 22 is pushed through The pipeline is connected to the water hole 23. When the two squeezing plates 16 repeatedly squeeze the sludge between them, the water pump 22 sucks the water in the box 4, and a filter is provided on the inner wall of the water hole 23 to prevent the sludge from flowing out of the water hole 23.

When moving the desludging machine, release the fixation of the fixing mechanism 7 on the moving mechanism 8, so that the moving mechanism 8 contacts the ground again, and then pull the first L-shaped plate while lifting the support block 9 upwards. When the support block 9 returns to its original position, release the pulling of the first L-shaped plate. Finally, move the four support blocks 9 to their original positions. In the fixing mechanism 7, one end of the second L-shaped plate is slidably set on the inner wall of the support plate 801, so that the second L-shaped plate and the support plate 801 are fixed together in the vertical direction. By setting the moving mechanism 8 and the fixing mechanism 7, it is more convenient to change the position of the desludging machine.

[0037] The lower end surface of the storage box 2 is fixedly arranged on the upper end surface of the base 1, and the lower end surface of the box body 4 is fixedly arranged on the upper end surface of the storage box 2.

When the four support blocks 9 are put down, turn on the second bidirectional motor 701. The second bidirectional motor 701 drives the two second L-shaped plates to leave the inner wall of the base 1 through the third screw rod 702 and the sleeve column 703. At this time, lift the support plate 801 upward. When the support plate 801 cannot be lifted further, control the second bidirectional motor 701 to reverse, so that the second L-shaped plate Into the inner wall of the support plate 801.
