Efficient sludge cleaning mechanism

The invention provides an efficient sludge cleaning mechanism. The problems that the cost is high, and the efficiency is low in a dry-method sludge cleaning operation are effectively solved. The technical scheme is that the efficient sludge cleaning mechanism comprises a base plate, two vertical stand plates are respectively arranged on the two sides of the base plate, rotary shafts are arranged between the two stand plates, coaxial small gears are respectively fixed to the two ends of the rotary shafts, and four large gears engaged with the small gears are arranged on the peripheries of the small gears; a sludge digging plate is arranged in the front of the stand plate, longitudinal rods are respectively arranged on the rear sides of the left end and the right end of the sludge digging plate, and the small gears rotates to drive the large gears arranged on the peripheries of the small gears to rotate synchronously; a spline shaft is arranged between the stand plates, a spline tube isarranged on the spline sh
