The invention belongs to the technical field of excavator crawler cleaning devices, and especially relates to an excavator crawler soil cleaning device, which comprises a rack, an end surface washing device and a side washing device. The rack can be fixedly connected to the bottom of the driving cab of an excavator through bolts. The end surface washing device is installed below the rack. The side washing device is installed below the rack. The end surface washing device comprises a first screw, a first sliding base, a first polished pole, a first motor, a rodless cylinder and a cleaning unit. The side washing device comprises moving units, a mounting bracket and side washing units. Each of the moving units comprises a gear, a rack and a second motor. The cleaning unit comprises a cleaning brush rod, a connecting rod, a first cylinder, a sliding column, a blade and a first wire brush. The excavator crawler soil cleaning device can clean soil deposited on the surface and sides of a crawler, thereby reducing the load of the excavator so as to increase the moving speed of the excavator, improving the working efficiency, and reducing the fuel consumption of the excavator to save energy resources.
