When the telescopic end of the fourth electric telescopic assembly is extended to touch the limit switch 38, the limit switch 38 sends a signal to the control box 6, and the control box 6 controls the fourth electric telescopic assembly to stop, so that the loading and storage bucket 31 reaches the position;

[0071] After the automatic cleaning device travels a certain distance, the cleaning motor 27 of the sludge cleaning mechanism is first controlled by the control box 6 to start, and the cleaning motor 27 drives the spiral cleaning component 26 to rotate, and then the third electric telescopic component 19 of the sludge cleaning mechanism is controlled by the control box 6 to start, and the third electric telescopic component 19 adjusts the spiral cleaning component 26 to fall to the bottom of the ditch. The descending height of the spiral cleaning component 26 is controlled by the distance sensor 39. When the spiral cleaning component 26 reaches the position, the distance sensor 39 sends a signal to the control box 6, and the control box 6 controls the third electric telescopic component 19 to stop; after the spiral cleaning component 26 descends, it rotates to throw the loose sludge at the bottom of the ditch to the rear of the center of the ditch and load it into the loading and storage bucket 31 of the sludge loading and unloading mechanism.

[0072] Step 6), when the automatic cleaning device moves a certain distance along the ditch, the sludge in the loading and storage bucket 31 is filled, and the fourth electric telescopic component is controlled to start through the control box 6. The fourth electric telescopic component adjusts the loading and storage bucket 31 to rise and extend out of the ditch and then stops. A moving trolley is set up above the ditch, and then the fifth electric telescopic component 35 is controlled to start through the control box 6. The fifth electric telescopic component 35 telescopes and adjusts the loading and storage bucket 31 to flip over the trolley to unload the sludge, thereby completing the cleaning of a section of the ditch.

[0073] Step 7), the fourth electric telescopic assembly is started again by controlling the control box 6, and the fourth electric telescopic assembly adjusts the loading storage bucket 31 to descend and extend into the bottom of the ditch again to continue cleaning the ditch.

[0074] Step 8), repeat step 6) to step 7) until the automatic cleaning device reaches the end position of the ditch, completing the cleaning of the entire ditch.

[0075] Step 9), when the sludge is cleaned, the first rotary tillage component 13, the second rotary tillage component 14 and the spiral cleaning component 26 are controlled by the control box 6 to return to their original positions and stop running, and the positioning wheel 29 is adjusted to move and separate from the two side walls of the ditch.

[0076] Step 10), take out the entire automatic cleaning device from the end of the ditch.

[0077] In the cleaning method of the present invention, the control box 6 controls the actions of all moving parts, which belongs to the automatic control of the prior art, and the present invention will not be described in detail here. The cleaning method of the present invention can realize automatic cleaning of the ditch through the control box programming program.
