The first motor 510 and the second motor 515 start to rotate reversely to drive the first slider 514 and the second slider 519 to move leftwards respectively, when the first motor 510 and the second motor 515 move leftwards, the first travel switch 531 and the second travel switch 532 sense the distance between the raking rod 541 and the first travel switch 531 and the second travel switch 532 in real time, when the raking rod 541 approaches the first travel switch 531 and the second travel switch 532, the first travel switch 531 and the second travel switch 532 send stop signals to the controller 530, the controller 530 transmits the stop signals to the first motor 510 and the second motor 515 respectively and simultaneously, the first motor 510 and the second motor 515 stop running, the raking rod 541 stops moving, the raking teeth 544 on the raking rod 541 rake sludge to a discharge port at the left end, rake sludge to the discharge port in one reciprocating motion cycle, and achieve the purpose of quickly raking sludge.

The first motor 510 and the second motor 515 are utilized to respectively drive the first sliding block 514 and the second sliding block 519 to drive the raking rod 541 to do reciprocating motion on the guide rail mechanism 52, so that the sludge is raked out to the discharge hole. The second controller 530 controls the switching groove 542 to switch the position of the rake teeth, so that the purpose of raking the sludge at one time is achieved, the time for raking the sludge is saved, and the working efficiency is improved.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the present invention.
